When the third transmission means is rotationally moved toward the other side in the rotation direction, the third transmission means is pressed by the third tooth portion via the fourth transmission means to rotate and move in the power generation rotation direction. The tooth portion, the second tooth portion, and the third tooth portion were formed.

Further, the power generation system according to claim 2 is a power generation system that converts an external force into electricity via a power generation means, and the external force is a wave force, which is a rotation direction of one direction in which power can be generated. The power generation means having a rotation axis that rotates only in a direction, and a rotational force conversion means that converts the external force into a rotational force in the power generation rotation direction and transmits the converted rotational force to the power generation means.

A second transmission means that can rotate only in the same direction as the power generation rotation direction, and in the plane of a virtual plane orthogonal to the rotation center axis of each of the first transmission means and the second transmission means. When the external force is applied to the pressing means, the first transmitting means, or the second transmitting means, the first transmitting means, the second transmitting means, and the pressing means are relative to each other along the virtual surface. By linearly moving to, the pressing means is formed so that either the first transmitting means or the second transmitting means is pressed and rotationally moved by the pressing means, and the power generating means is relative to the above. When the linear movement is a movement in one of the linear movement directions, the rotation shaft is rotated by the rotational force transmitted by the first transmission means to generate power.

When a connecting portion for connecting the receiving portion is provided and the relative linear movement is a movement in one of the moving directions of the linear movement. In the case where the first transmission means is pressed by the first tooth portion to rotate and move in the power generation rotation direction, and the relative linear movement is a movement toward the other movement direction of the linear movement. The first tooth portion and the second tooth portion are formed so that the second transmission means is pressed by the second tooth portion and rotationally moves in the power generation rotation direction, and the relative linear movement movement is performed. In the case where the direction is an oblique vertical direction, when the horizontal component force is applied to the receiving portion, the pressing means is in one of the relative linear moving directions, that is, the upward oblique direction. By moving linearly toward, either the first tooth portion or the second tooth portion presses either the first transmission means or the second transmission means to rotate and move, and the pressing When the horizontal component force is no longer applied to the receiving portion after the means moves linearly in the upward oblique direction, the pressing means moves linearly as the pressing means lowers its own weight. By linearly moving in the downward oblique direction, which is the other direction of the moving direction, either the first tooth portion or the second tooth portion can be used by either of the first transmission means or the second transmission means. The first transmission means, the second transmission means, and the pressing means are installed so that the other is pressed and rotates.

Further, in the power generation system according to claim 3, in the power generation system according to claim 2, when the pressing means linearly moves in the upward oblique direction, wave water flows into the inside of the receiving portion. The receiving portion is formed so that the inflowing water flows out of the receiving portion when the pressing means linearly moves in the downward oblique direction.

The relative of the pressing means is provided with the accommodating means provided at various positions, and the internal shape of the accommodating means is amplified by the wave flowing into the accommodating means to amplify the internal water level of the accommodating means. It was formed into a shape capable of promoting linear movement.

The power generation system according to claim 5 is a power generation system that converts an external force into electricity via a power generation means, and the external force is a wave force, which is a rotation direction of one direction in which power can be generated. The power generation means having a rotation axis that rotates only in a direction, and a rotational force conversion means that converts the external force into a rotational force in the power generation rotation direction and transmits the converted rotational force to the power generation means. The rotational force conversion means is for pressing the transmission means for transmitting the rotational force to the power generation means and the transmission means so that the transmission means can rotate and move by rotating itself. The transmission means includes a pressing means, and the transmission means is a first transmission means that can rotate only in the same direction as the power generation rotation direction, and a second transmission means that is provided at a distance from the first transmission means. A second transmission means that can rotate only in the same direction as the power generation rotation direction, and the power generation system is a first floating body portion that is at least partially floatable on the water surface and is deformable. The first floating body portion formed of a substantially U-shaped hollow body, the first transmitting means, and the second floating body portion so that the liquid can be accommodated only in a part of the inside of the first floating body portion. A second floating body portion located below the transmitting means and capable of floating on the liquid housed in the first floating body portion, and the first transmitting means and the second transmitting means. A connecting portion for connecting the second floating body portion is further provided, and the first transmitting means and the second transmitting means are inside each of the pair of substantially U-shaped vertical bar portions in the first floating body portion. The pressing means, the pressing means, and the pressing means, which accommodates the second floating body portion and the connecting portion, and in the plane of a virtual surface orthogonal to the rotation center axis of each of the first transmitting means and the second transmitting means. When the external force is applied to the first transmission means or the second transmission means, the first transmission means, the second transmission means, and the pressing means move relatively linearly along the virtual surface. By doing so, the pressing means is formed so that either the first transmitting means or the second transmitting means is pressed and rotationally moved by the pressing means, and the power generating means has the relative straight line. When the movement is a movement in one movement direction of the linear movement, the rotation shaft is rotated by the rotational force transmitted by the first transmission means to generate power, and the relative movement is performed. When the linear movement is a movement in the other movement direction of the linear movement, the rotation is caused by the rotational force transmitted by the second transmission means. Power is generated by rotating the shaft, and the pressing means is a first tooth portion provided along the moving direction of the relative linear movement, and is arranged so as to be in contact with the first transmitting means. A second tooth portion provided along the movement direction of the relative linear movement at a position separated from the first tooth portion and the first tooth portion so as to be in contact with the second transmission means. The first transmission means is pressed by the first tooth portion when the relative linear movement is a movement in one movement direction of the linear movement. Then, the second transmission means is pressed by the second tooth portion when the linear movement is rotationally moved in the power generation rotation direction and the relative linear movement is a movement in the other moving direction of the linear movement. The first tooth portion and the second tooth portion are formed so as to rotate and move in the power generation rotation direction, and when the movement direction of the relative linear movement is the vertical direction, the vertical direction of the wave force. When a component force is applied to one of the pair of vertical bar portions, the first floating body portion is provided so that the levels of the second floating body portions accommodated in each of the pair of vertical bar portions are substantially the same. The first transmission means and the second transmission means housed in one of the pair of vertical bar portions are directed upward, which is one of the relative linear movement directions, while deforming. By moving linearly, either the first tooth portion or the second tooth portion of the pressing means presses either the first transmission means or the second transmission means to rotate and move. After the first transmitting means and the second transmitting means accommodated in one of the pair of vertical bar portions linearly move upward, the vertical component force is no longer applied to one of the pair of vertical rod portions. In this case, the first transmission means and the second floating body portion are deformed so that the levels of the second floating body portions housed in each of the pair of vertical bar portions are substantially the same. As the weight of the transmitting means is lowered, the first transmitting means and the second transmitting means linearly move downward, which is the other direction of the relative linear moving directions, thereby causing the pressing means. The first transmission means, the first, so that either the first transmission means or the second transmission means is pressed and rotationally moved by either the first tooth portion or the second tooth portion. 2 Transmission means and the pressing means were installed.

The power generation system according to claim 6 is a power generation system that converts an external force into electricity via a power generation means, and has a rotation axis that rotates only in the power generation rotation direction, which is a rotation direction in one direction in which power can be generated. The power generation means, the rotational force conversion means for converting the external force into the rotational force in the power generation rotational direction and transmitting the converted rotational force to the power generation means, and the collecting means for collecting waves are provided. The rotational force conversion means presses the transmission means for transmitting the rotational force to the power generation means and the transmission means so that the transmission means can rotate and move by rotating itself. The transmission means is a first transmission means that can rotate only in the same direction as the power generation rotation direction, and a second transmission means that is provided at a distance from the first transmission means. A second transmitting means that can rotate only in the same direction as the power generation rotation direction is provided, and the collecting means has a first reflecting means having a first parabolic surface and a second reflecting means having a second parabolic surface. The pressing means, the first transmitting means, or the second transmitting means, comprising a reflecting means, in a plane of a virtual surface orthogonal to the rotation center axis of each of the first transmitting means and the second transmitting means. When the external force is applied to the body, the first transmission means, the second transmission means, and the pressing means move relatively linearly along the virtual surface, so that the first transmission means is transmitted by the pressing means. The pressing means is formed so that either the means or the second transmitting means is pressed and rotationally moved, and the power generating means directs the relative linear movement toward one of the linear movements. In the case of all movements, the rotation axis is rotated by the rotational force transmitted by the first transmission means to generate power, and the relative linear movement is in the other movement direction of the linear movement. In the case of movement toward, the rotation shaft is rotated by the rotational force transmitted by the second transmission means to generate power, and the opening diameter of the first parabolic surface is set to the second release. The first reflecting means and the second reflecting means are arranged so as to be larger than the opening diameter of the object surface so that the first release surface and the second release surface face each other. Either one of the first transmission means or the second transmission means is pressed by the pressing means by using the wave force of the wave collected between the first release surface and the second release surface. It can be rotated and moved.

The power generation system according to claim 7 is a power generation system that converts an external force into electricity via a power generation means, and has a rotation axis that rotates only in the power generation rotation direction, which is a rotation direction in one direction in which power can be generated. The power generation means and the rotational force conversion means for converting the external force into the rotational force in the power generation rotation direction and transmitting the converted rotational force to the power generation means are provided, and the rotational force conversion means is self-rotating. The transmission is provided with a transmission means for transmitting the rotational force to the power generation means by moving and a pressing means for pressing the transmission means so that the transmission means can rotate and move. The means are a first transmission means that can rotate only in the same direction as the power generation rotation direction and a second transmission means that is provided at intervals from the first transmission means and has the same direction as the power generation rotation direction. The pressing means, the first transmitting means, which comprises a second transmitting means which can only rotate, and in a plane of a virtual surface orthogonal to the rotation center axis of each of the first transmitting means and the second transmitting means. Alternatively, when the external force is applied to the second transmission means, the first transmission means, the second transmission means, and the pressing means move relatively linearly along the virtual surface, whereby the pressing is performed. The pressing means is formed so that either the first transmitting means or the second transmitting means is pressed and rotationally moved by the means, and the power generating means has the relative linear movement of the linear movement. When the movement is in one movement direction, the rotation axis is rotated by the rotational force transmitted by the first transmission means to generate power, and the relative linear movement is the linear movement. When the movement is in the other direction of movement, the rotation shaft is rotated by the rotational force transmitted by the second transmission means to generate power, and the first transmission means or the second transmission means or the second. The first transmission means or the second transmission means is formed so that either one of the transmission means rotates at a lower speed or a higher speed than the other of the first transmission means or the second transmission means.

According to the power generation system according to claim 1, the pressing means, the first transmitting means, or the second transmitting means is provided in a plane of a virtual surface orthogonal to the rotation center axis of each of the first transmitting means and the second transmitting means. When an external force is applied to the transmission means, the first transmission means, the second transmission means, and the pressing means move relatively linearly along the virtual surface, so that the first transmission means causes the first transmission. The pressing means is formed so that either the means or the second transmitting means is pressed and rotationally moved, and the power generating means has the relative linear movement directed to the one moving direction of the linear movement. In the case of movement, the rotation axis is rotated by the rotational force transmitted by the first transmission means to generate power, and the relative linear movement is the movement in the other movement direction of the linear movement. In this case, since the rotating shaft is rotated by the rotational force transmitted by the second transmission means to generate power, the first transmission means and the second transmission means are distributed on the market (for example, ratchet gear, etc.). ), And it is not necessary to configure it with a special structure, so that it is possible to improve the manufacturability of the power generation system and reduce the manufacturing cost.
Further, when the relative linear movement is a movement in one of the linear movement directions, the first transmission means is pressed by the first tooth portion to rotate and move in the power generation rotation direction, and the relative movement is performed. When the linear movement is a movement in the other movement direction of the linear movement, the first tooth is rotated in the power generation rotation direction by pressing the second transmission means by the second tooth portion. Since the portion and the second tooth portion are formed, when the pressing means moves relative linearly, either the first transmitting means or the second transmitting means is used depending on the pressing means regardless of the moving direction of the relative linear movement. Since one of them can be pressed so as to rotate and move in the power generation rotation direction, it is possible to reliably generate power.
Further, when the pressing means rotates and moves toward one of the rotation directions in the in-plane rotation of the virtual surface, the first and second tooth portions press the first transmitting means and the second transmitting means to generate power. When the pressing means rotates and moves in the direction toward the other side of the rotation direction in the in-plane rotation of the virtual surface, the third transmission means is pressed by the third tooth portion via the fourth transmission means to generate power. Since the first tooth portion, the second tooth portion, and the third tooth portion are formed so as to rotate and move in the rotation direction, the pressing means rotates and moves regardless of the rotation direction in the in-plane rotation of the virtual surface. In this case, the pressing means can press the first transmitting means, the second transmitting means, or the third transmitting means so as to rotate and move in the power generation rotation direction. As a result, as compared with the case where the third transmission means, the fourth transmission means, and the third tooth means are not provided, power can be generated regardless of the rotation direction in the in-plane rotation of the virtual surface of the pressing means. The amount can be increased.

According to the power generation system according to claim 2 , the pressing means, the first transmitting means, or the second transmitting means, or the second transmitting means, in the plane of the virtual surface orthogonal to the rotation center axis of each of the first transmitting means and the second transmitting means. When an external force is applied to the transmission means, the first transmission means, the second transmission means, and the pressing means move relatively linearly along the virtual surface, so that the first transmission means causes the first transmission. The pressing means is formed so that either the means or the second transmitting means is pressed and rotationally moved, and the power generating means has the relative linear movement directed to the one moving direction of the linear movement. In the case of movement, the rotation axis is rotated by the rotational force transmitted by the first transmission means to generate power, and the relative linear movement is the movement in the other movement direction of the linear movement. In this case, since the rotating shaft is rotated by the rotational force transmitted by the second transmission means to generate power, the first transmission means and the second transmission means are distributed on the market (for example, ratchet gear, etc.). ), And it is not necessary to configure it with a special structure, so that it is possible to improve the manufacturability of the power generation system and reduce the manufacturing cost.
Further, when the relative linear movement is a movement in one of the linear movement directions, the first transmission means is pressed by the first tooth portion to rotate and move in the power generation rotation direction, and the relative movement is performed. When the linear movement is a movement in the other movement direction of the linear movement, the first tooth is rotated in the power generation rotation direction by pressing the second transmission means by the second tooth portion. Since the portion and the second tooth portion are formed, when the pressing means moves relative linearly, either the first transmitting means or the second transmitting means is used depending on the pressing means regardless of the moving direction of the relative linear movement. Since one of them can be pressed so as to rotate and move in the power generation rotation direction, it is possible to reliably generate power.
Further, when the relative linear movement is in the vertical and diagonal directions, and a horizontal component force is applied to the receiving portion, the pressing means linearly moves in the upward diagonal direction, whereby the main body is moved. When the transmitting means is pressed by the portion and rotates and moves, and the horizontal component force is no longer applied to the receiving portion after the pressing means moves linearly in the upward diagonal direction, the weight of the pressing means drops. Since the transmitting means and the pressing means are installed so that the transmitting means is pressed and rotationally moved by the main body when the pressing means moves linearly in the downward oblique direction, the pressing means is vertically obliquely moved. It is possible to generate power by using the wave force and the weight of the pressing means when moving relatively linearly toward the direction, and the relative moving direction of the linear movement is compared with the case where power is generated using only the wave force. Regardless of this, it is possible to reliably generate power in the power generation system.

Further, according to the power generation system according to claim 3, when the pressing means linearly moves in the upward diagonal direction, wave water flows into the receiving portion and the pressing means straights in the downward diagonal direction. Since the receiving portion is formed so that the water that has flowed in when it moves flows out to the outside of the receiving portion, the pressing means is relatively linearly moved downward by the weight of the water that has flowed into the receiving portion. This makes it possible to reliably perform the relative linear movement of the pressing means as compared with the case where the receiving portion is formed so that the water of the wave does not flow into the receiving portion.

Further, according to the power generation system according to claim 4, the internal shape of the accommodating means is formed into a relative straight line of the accommodating means by amplifying the internal water level of the accommodating means by a wave flowing into the accommodating means. Since it is formed into a shape that can promote movement, the internal water level of the accommodating means is amplified when a wave flows into the accommodating means, as compared with the case where the internal shape of the accommodating means is made uniform. At the same time, when the inflowing wave flows out of the accommodating means, the internal water level of the accommodating means can be rapidly lowered. Therefore, the relative linear movement of the pressing means can be effectively performed, and the amount of power generated by the power generation system can be increased.

According to the power generation system according to claim 5 , the pressing means, the first transmitting means, or the second transmitting means, or the second transmitting means, in the plane of the virtual surface orthogonal to the rotation center axis of each of the first transmitting means and the second transmitting means. When an external force is applied to the transmission means, the first transmission means, the second transmission means, and the pressing means move relatively linearly along the virtual surface, so that the first transmission means causes the first transmission. The pressing means is formed so that either the means or the second transmitting means is pressed and rotationally moved, and the power generating means has the relative linear movement directed to the one moving direction of the linear movement. In the case of movement, the rotation axis is rotated by the rotational force transmitted by the first transmission means to generate power, and the relative linear movement is the movement in the other movement direction of the linear movement. In this case, since the rotating shaft is rotated by the rotational force transmitted by the second transmission means to generate power, the first transmission means and the second transmission means are distributed on the market (for example, ratchet gear, etc.). ), And it is not necessary to configure it with a special structure, so that it is possible to improve the manufacturability of the power generation system and reduce the manufacturing cost.
Further, when the relative linear movement is a movement in one of the linear movement directions, the first transmission means is pressed by the first tooth portion to rotate and move in the power generation rotation direction, and the relative movement is performed. When the linear movement is a movement in the other movement direction of the linear movement, the first tooth is rotated in the power generation rotation direction by pressing the second transmission means by the second tooth portion. Since the portion and the second tooth portion are formed, when the pressing means moves relative linearly, either the first transmitting means or the second transmitting means is used depending on the pressing means regardless of the moving direction of the relative linear movement. Since one of them can be pressed so as to rotate and move in the power generation rotation direction, it is possible to reliably generate power.
Further, when the movement direction of the relative linear movement is the vertical direction and the vertical component force of the wave force is applied to one of the pair of vertical bar portions, each of the pair of vertical bar portions. While deforming the first floating body portion so that the levels of the housed second floating body portion are substantially the same, the first transmitting means and the second transmitting means housed in one of the pair of vertical bar portions are relative to each other. By linearly moving in the upward direction, which is one of the moving directions of the linear movement, the first transmission means or the second transmission is performed by either the first tooth portion or the second tooth portion of the pressing means. One of the means is pressed and rotates, and after the first transmission means and the second transmission means housed in one of the pair of vertical bar portions move linearly upward, the vertical component force is applied to the pair. When it is no longer added to one of the vertical bar portions, the first floating body portion is deformed so that the levels of the second floating body portions accommodated in each of the pair of vertical bar portions are substantially the same. As the weight of the first transmission means and the second transmission means drops, the first transmission means and the second transmission means move linearly downward, which is the other direction of the relative linear movements. By doing so, the first transmission means that either the first tooth portion or the second tooth portion of the pressing means presses and rotates the first transmission means or the second transmission means. Since the means, the second transmission means, and the pressing means are installed, for example, even when the power generation system is installed offshore, the vertical component force required for power generation can be obtained, so that the vertical component force can be obtained. It can be used to generate a desired amount of power.

According to the power generation system according to claim 6 , the pressing means, the first transmitting means, or the second transmitting means, or the second transmitting means, in the plane of the virtual surface orthogonal to the rotation center axis of each of the first transmitting means and the second transmitting means. When an external force is applied to the transmission means, the first transmission means, the second transmission means, and the pressing means move relatively linearly along the virtual surface, so that the first transmission means causes the first transmission. The pressing means is formed so that either the means or the second transmitting means is pressed and rotationally moved, and the power generating means has the relative linear movement directed to the one moving direction of the linear movement. In the case of movement, the rotation axis is rotated by the rotational force transmitted by the first transmission means to generate power, and the relative linear movement is the movement in the other movement direction of the linear movement. In this case, since the rotating shaft is rotated by the rotational force transmitted by the second transmission means to generate power, the first transmission means and the second transmission means are distributed on the market (for example, ratchet gear, etc.). ), And it is not necessary to configure it with a special structure, so that it is possible to improve the manufacturability of the power generation system and reduce the manufacturing cost.
Further, the opening diameter of the first paraboloid is made larger than the opening diameter of the second paraboloid, so that the first paraboloid and the second paraboloid face each other with the first reflecting means. A second paraboloid is arranged, and either the first or second paraboloid is used by the pressing means by using the wave power of the wave collected between the first paraboloid and the second paraboloid. Since one of them is pressed and made rotatable, the first transmission means or the second transmission by the pressing means is performed by amplifying the water level between the two, as compared with the case where a wave other than the waves collected between the two is used. The pressing of the means can be effectively performed, and the amount of power generated by the power generation system can be increased.

According to the power generation system according to claim 7 , the pressing means, the first transmitting means, or the second transmitting means, or the second transmitting means, in the plane of a virtual surface orthogonal to the rotation center axis of each of the first transmitting means and the second transmitting means. When an external force is applied to the transmission means, the first transmission means, the second transmission means, and the pressing means move relatively linearly along the virtual surface, so that the first transmission means causes the first transmission. The pressing means is formed so that either the means or the second transmitting means is pressed and rotationally moved, and the power generating means has the relative linear movement directed to the one moving direction of the linear movement. In the case of movement, the rotation axis is rotated by the rotational force transmitted by the first transmission means to generate power, and the relative linear movement is the movement in the other movement direction of the linear movement. In this case, since the rotating shaft is rotated by the rotational force transmitted by the second transmission means to generate power, the first transmission means and the second transmission means are distributed on the market (for example, ratchet gear, etc.). ), And it is not necessary to configure it with a special structure, so that it is possible to improve the manufacturability of the power generation system and reduce the manufacturing cost.
Further, the first transmission means or the second transmission means is rotated so that either one of the first transmission means or the second transmission means rotates at a lower speed or a higher speed than the other of the first transmission means or the second transmission means. Since the transmitting means is formed, when the moving efficiency of the pressing means differs depending on the moving direction of the relative linear movement in the pressing means, the rotating speed of the first transmitting means or the second transmitting means is changed to cause the pressing means. The movement efficiency can be improved, and the power generation efficiency of the power generation system can be maintained.

(Structure-Details of the configuration of the housing)
Next, the details of the configuration of the accommodating portion 10 will be described. FIG. 4 is a perspective view showing a front side portion of the accommodating portion 10. In the first embodiment, as shown in FIG. 4, the accommodating portion 10 includes a first accommodating portion 11 and a second accommodating portion 12.

The first accommodating portion 11 is a portion accommodating a part of the pressing portion 20 (specifically, a receiving portion 22 or the like described later), and as shown in FIG. 4, at least the first accommodating portion 11 is located offshore. A part of the front part is installed so that it is always located in the water. The second accommodating portion 12 is a portion accommodating another part of the pressing portion 20 (specifically, the main body portion 21 or the like described later), the first transmission unit 30a, the second transmission unit 30b, and the power generation unit 80. Yes, as shown in FIG. 4, it is provided on land (breakwater) and is connected to the first accommodation portion 11. The details of the internal shapes of the first accommodating portion 11 and the second accommodating portion 12 are arbitrary, but in the first embodiment, the inside of the accommodating portion 10 is caused by the wave flowing into the inside of the accommodating portion 10. By amplifying the water level, it is formed in a shape capable of promoting the relative linear movement of the pressing portion 20 described later. Specifically, regarding the internal shape of the first accommodating portion 11, as shown in FIG. 4, the vertical length of the inner diameter does not change from the land side to the offshore side, but the inner diameter It is formed in an annular shape in which the length in the left-right direction becomes longer from the land side to the offshore side (specifically, an annular ring in which the inner diameter of the first accommodating portion 11 becomes longer than the length in the vertical direction). .. Regarding the internal shape of the second accommodating portion 12, the length of the inner diameter in the left-right direction and the length in the up-down direction does not change from the land side to the offshore side (specifically, the first ring). 1 It is formed of an elliptical ring that is substantially the same as the inner diameter of the land-side end of the accommodating portion 11. Due to such a shape, the inside of the accommodating portion 10 when a wave flows into the accommodating portion 10 as compared with the case where the internal shapes of the first accommodating portion 11 and the second accommodating portion 12 are made uniform. The water level can be amplified, and when the inflowing wave flows out of the accommodating portion 10, the internal water level of the accommodating portion 10 can be rapidly lowered. Therefore, the relative linear movement of the pressing portion 20 described later can be effectively performed, and the amount of power generated by the power generation system 1 can be increased. However, the internal shapes of the first accommodating portion 11 and the second accommodating portion 12 are not limited to the above shapes, and for example, the internal shape of the first accommodating portion 11 is substantially the same as the internal shape of the second accommodating portion 12. By forming the shape of the above, it may not be possible to promote the relative linear movement of the pressing portion 20 described later.

(Structure-Details of the configuration of the pressing part)

FIG. 5 is a perspective view showing a state in which the pressing portion 20 moves relative to the first transmission portion 30a and the second transmission portion 30b in a rearward and upward oblique direction, which will be described later. FIG. 6 is a perspective view showing a state in which the pressing portion 20 moves relative to the first transmission portion 30a and the second transmission portion 30b in a diagonal direction forward and downward, which will be described later. FIG. 7 is a perspective view showing a state in which the receiving portion 22 described later moves in a relative linear direction, which will be described later, and FIG. (B) is a diagram showing a state in which the receiving portion 22, which will be described later, moves in a relative linear movement described later in an oblique forward and downward direction. In the first embodiment, as shown in FIG. 1, the pressing portion 20 includes a main body portion 21, a receiving portion 22, and a connecting portion 23.

(Structure-Details of the configuration of the pressing part-Main body part)
The main body 21 is the basic structure of the pressing portion 20. As shown in FIGS. 1 to 3, the main body portion 21 is formed so that the side surface shape becomes a relatively thick substantially annular shape by combining a plurality of long frame portions. Specifically, these plurality of frame portions are arranged so as not to face the first frame portion 21a on the side of the first transmission portion 30a and the second transmission portion 30b. After the frame portion 21b, the third frame portion 21c connecting the front portion of the first frame portion 21a and the front portion of the second frame portion 21b, and the rear portion of the first frame portion 21a and the second frame portion 21b. It is composed of a fourth frame portion 21d that connects to the side portion.

Regarding the details of the shapes of the first frame portion 21a and the second frame portion 21b, in the first embodiment, the rotation center axis (first shaft 50) on which the first transmission portion 30a or the second transmission portion 30b rotates is used. Wave force is applied to the pressing portion 20 in the plane of the orthogonal virtual planes (in FIG. 1, the XZ plane virtually generated in the internal space of the main body portion 21 is referred to as a virtual plane; hereinafter referred to as a “virtual plane”). When a horizontal component force of (external force) is applied, the pressing unit 20 moves linearly with respect to the first transmission unit 30a and the second transmission unit 30b along the virtual surface (specifically, virtual). It is possible to secure a predetermined amount of movement (so-called stroke) when a relative linear movement substantially along the longitudinal direction of the surface (front-back, vertical, vertical, diagonal directions), hereinafter referred to as "relative linear movement"). It is formed in a shape. Here, regarding the setting of the "predetermined movement amount", for example, the movement amount is set so that the dynamo can generate a desired amount of power generation by the relative linear movement of the pressing portion 20. Specifically, the side surface shape of the first frame portion 21a is formed in a substantially inverted U shape, and more specifically, the length of the internal space partially surrounded by the first frame portion 21a. The length in the direction (approximately the front-back direction) is longer than the circumference of the first transmission unit 30a (for example, the length of an integral multiple (or a multiple other than an integral multiple) of the circumference of the first transmission unit 30a, etc.). The length of the internal space partially surrounded by the frame portion 21a in the lateral direction (substantially in the vertical direction) is formed to be substantially the same as the length in the vertical direction of the first transmission portion 30a. Further, the second frame portion 21b is formed so that the side surface shape is substantially U-shaped, and more specifically, the longitudinal direction of the internal space partially surrounded by the second frame portion 21b ( The length in the front-back direction is longer than the length of the circumference of the second transmission unit 30b (for example, the length of an integral multiple (or a multiple other than an integral multiple) of the circumference of the second transmission unit 30b, etc.). The length of the internal space partially surrounded by the two frame portions 21b in the lateral direction (substantially in the vertical direction) is formed to be substantially the same as the length in the vertical direction of the second transmission portion 30b. However, the present invention is not limited to this, and for example, the length of the first frame portion 21a in the longitudinal direction (substantially the front-rear direction) of the internal space is shorter than the circumference of the first transmission portion 30a (however, the first It may be formed so as to be longer than the length of the transmission portion 30a in the front-rear direction (the same applies to the second frame portion 21b).

Further, as shown in FIGS. 2 and 3, the first frame portion 21a is provided with the first tooth portion 24, and the second frame portion 21b is provided with the second tooth portion 25. The first tooth portion 24 is for pressing the first transmission portion 30a, and includes a plurality of protrusions 26. Further, as shown in FIG. 2, the first tooth portion 24 is arranged so as to be in contact with the first transmission portion 30a, and specifically, the first transmission portion in the horizontal bar portion of the first frame portion 21a. At the end portion on the 30a side (that is, the lower end portion of the horizontal bar portion), the pressing portion 20 is arranged along the moving direction of the relative linear movement. The second tooth portion 25 is for pressing the second transmission portion 30b, and includes a plurality of protrusions 26. Further, as shown in FIG. 2, the second tooth portion 25 is arranged so as to be in contact with the second transmission portion 30b. Specifically, the second transmission portion in the horizontal bar portion of the second frame portion 21b. Arranged along the relative linear movement direction of the pressing portion 20 at the end portion on the 30b side (that is, the upper end portion of the horizontal bar portion) (that is, at a position separated from the first tooth portion 24). Has been done.

The shape of the protrusion 26 in each of the first tooth portion 24 and the second tooth portion 25 is arbitrary, but in the first embodiment, the pressing portion 20 is in the upward oblique direction (specifically, rearwardly upward). When the relative linear movement is made toward the diagonal direction), the first transmission portion 30a is pressed by the first tooth portion 24 and rotationally moves in the power generation rotation direction, and the pressing portion 20 is pressed in the downward oblique direction (specifically, specifically). The second transmission portion 30b is pressed by the second tooth portion 25 and is formed so as to rotate in the power generation rotation direction when the relative linear movement is performed toward the front lower diagonal direction). Specifically, regarding the shape of the protrusion 26 of the first tooth portion 24, as shown in FIG. 5, the pressing portion 20 faces the first transmission portion 30a and the second transmission portion 30b in the rear-upward oblique direction. When the protrusion 26 of the first tooth portion 24 and the protrusion 40 of the first transmission portion 30a mesh with each other, the first tooth portion 24 presses the first transmission portion 30a, but FIG. As shown in the above, when the pressing portion 20 moves in the forward and downward oblique direction with respect to the first transmission portion 30a and the second transmission portion 30b, the protrusion 26 and the first transmission portion 30a of the first tooth portion 24 The protrusion 26 of the first tooth portion 24 is inclined and protrudes downward on the rear side so that the first transmission portion 30a is not pressed by the first tooth portion 24 due to the disengagement with the protrusion 40 of the first tooth portion 24. It is formed in. As for the shape of the protrusion 26 of the second tooth portion 25, as shown in FIG. 5, the pressing portion 20 has moved in the rear-upward oblique direction with respect to the first transmission portion 30a and the second transmission portion 30b. In this case, the protrusion 26 of the second tooth portion 25 and the protrusion 40 of the second transmission portion 30b do not mesh with each other, so that the second transmission portion 30b is not pressed by the second tooth portion 25, as shown in FIG. In addition, when the pressing portion 20 moves in the forward and downward oblique direction with respect to the first transmission portion 30a and the second transmission portion 30b, the protrusions 26 of the second tooth portion 25 and the protrusions of the second transmission portion 30b The protrusion 26 of the second tooth portion 25 is formed in a shape that is inclined and protrudes forward and upward so that the second transmission portion 30b is pressed by the second tooth portion 25 by engaging with the 40. There is. Due to such a shape, when the pressing portion 20 moves in a relative linear motion, the pressing portion 20 causes either the first transmission portion 30a or the second transmission portion 30b to move regardless of the moving direction of the relative linear movement. It can be pressed so as to rotate in the direction of power generation rotation. Therefore, as compared with the case where the protrusions 26 of the first tooth portion 24 and the second tooth portion 25 are inclined and protrude toward the front upper side (or the rear side lower side), the relative linear movement is caused. In the case of movement in one of the moving directions, it is possible to avoid the inability to generate electricity because the first transmission portion 30a and the second transmission portion 30b are not pressed by the first tooth portion 24 or the second tooth portion 25. , It is possible to generate electricity reliably.

(Structure-Details of the configuration of the pressing part-Receiving part)
The receiving portion 22 receives the horizontal component of the wave force, and as shown in FIGS. 1 and 7, it is a long block-shaped body (specifically, a rectangular body long in the left-right direction). It is formed by, and is installed so as to be located below the main body portion 21. The specific configuration of the receiving portion 22 is arbitrary, but in the first embodiment, as shown in FIG. 7A, the pressing portion 20 is in the upward oblique direction (specifically, the rearward oblique direction). ), The water of the wave flows into the receiving portion 22 when the relative linear movement is made toward), and as shown in FIG. 7B, the pressing portion 20 is directed in the downward oblique direction (forward and downward oblique direction). The water that has flowed in when the relative linear movement is performed is formed so as to flow out to the outside of the receiving portion 22. Specifically, first, as shown in FIGS. 1 and 7, the front side portion of the receiving portion 22 is formed in a concave shape protruding in the rear direction, as compared with the case where the receiving portion 22 is not formed in the concave shape. Therefore, the amount of water flowing in and out of the wave at the receiving portion 22 can be increased. Further, as shown in FIGS. 1 and 7, the pressing portion 20 is obliquely forward and downward due to the provision of the return portion 22a protruding upward from the lower end portion at the lower end portion of the front side portion of the receiving portion 22. It is possible to prevent a part of the water flowing into the receiving portion 22 from flowing out when the relative linear movement is performed in the direction. With such a receiving portion 22, the pressing portion 20 can be relatively linearly moved downward (specifically, in the front-down oblique direction) by the weight of the water flowing into the receiving portion 22. Compared with the case where the receiving portion 22 is formed so that the water of the wave does not flow into the inside of the portion 22, the relative linear movement of the pressing portion 20 can be surely performed.

Further, as shown in FIGS. 1 and 7, a moving portion 22b is provided at the lower end portion of the receiving portion 22. The moving portion 22b is a moving means for moving the pressing portion 20 by utilizing the horizontal component force of the wave force. The moving portion 22b is configured by using, for example, a known roller member such as a wheel member, and is fixed to the receiving portion 22 by a rotatable fixture or the like.

(Structure-Details of the configuration of the pressing part-Connecting part)
The connecting portion 23 connects the main body portion 21 and the receiving portion 22. As shown in FIG. 1, the connecting portion 23 is formed of a long substantially rod-shaped body, is arranged between the main body portion 21 and the receiving portion 22, and the front end portion of the connecting portion 23 is the receiving portion. It is connected to 22 by welding or the like, and the rear end of the connecting portion 23 is connected to the main body 21 by welding or the like.

(Structure-Details of installation positions of pressing unit, first transmission unit, and second transmission unit)
Next, the installation positions of the pressing unit 20, the first transmission unit 30a, and the second transmission unit 30b will be described. Regarding the details of the installation positions of the pressing unit 20, the first transmission unit 30a, and the second transmission unit 30b, in the first embodiment, as shown in FIG. 5, the horizontal component force of the wave in the plane of the virtual surface Is added to the receiving portion 22, the pressing portion 20 moves relatively linearly in the upward diagonal direction (specifically, the rearward upward diagonal direction), so that the main body portion 21 causes the first transmission portion 30a. Is pressed and rotates, and as shown in FIG. 6, when the horizontal component force is no longer applied to the receiving portion 22 after the pressing portion 20 moves in a relative linear direction in the upward diagonal direction, the pressing portion 22 is pressed. The second transmission portion 30b is pressed by the main body portion 21 by the pressing portion 20 relatively linearly moving in the downward oblique direction (specifically, the forward downward oblique direction) as the weight of the portion 20 drops. The pressing unit 20, the first transmission unit 30a, and the second transmission unit 30b are installed so as to rotate and move. Specifically, as shown in FIG. 2, the protrusions of the first transmission unit 30a are provided in a state where the first transmission unit 30a and the second transmission unit 30b are housed along the virtual surface in the internal space of the main body unit 21. The portion 40 is installed so that the protrusion 26 of the first tooth portion 24 can come into contact with each other, and the protrusion 40 of the second transmission portion 30b and the protrusion 26 of the second tooth portion 25 can come into contact with each other. It is installed so that it becomes. Further, regarding the contact state between the first transmission portion 30a and the first tooth portion 24, the pressing portion 20 moves relatively linearly, so that the first transmission portion 30a is pressed by the first tooth portion 24 and can rotate. As for the contact state between the second transmission portion 30b and the second tooth portion 25, the pressing portion 20 moves relatively linearly, so that the second transmission portion 30b is moved by the second tooth portion 25. It is pressed and touched so that it can rotate and move. With such an installation position, when the pressing portion 20 moves relatively linearly upward and downward, it is possible to generate electricity by using the wave power and the own weight of the pressing portion 20, so that only the wave power is used. Compared with the case of generating power, it is possible to reliably generate power of the power generation system 1 regardless of the moving direction of the relative linear movement. In such an installation position, the first transmission unit 30a and the second transmission unit 30b may fall off from the pressing portion 20 toward the left or right. For example, in order to prevent this dropout. A dropout prevention unit (not shown) may be provided in the first transmission unit 30a and the second transmission unit 30b (or the pressing unit 20).

With the structure of the power generation system 1 as described above, the first transmission unit 30a and the second transmission unit 30b can be composed of parts (for example, ratchet gears) on the market, and thus are configured with a special structure. Since it is not necessary to do so, it is possible to improve the manufacturability of the power generation system 1 and reduce the manufacturing cost. Further, in particular, even when the power generation system 1 is installed on land (breakwater), the horizontal component force required for power generation can be obtained, and the desired amount of power generation can be generated using the horizontal component force. it can. Therefore, as compared with the case where the power generation system 1 is installed offshore, the installation work of the power generation system 1 (for example, the power generation system 1) while avoiding hindering the use of the water area used for the fishing lane, the shipping route, etc. It is possible to reduce the time and effort required for installing an electric cable that connects the power generation unit 80 and an external device (such as a power storage unit) provided on land.

(Configuration-Power generation system function)
The function of the power generation system 1 configured in this way will be described.

First, for example, as shown in FIG. 5, when a horizontal component force of a wave is applied to the receiving portion 22 in the plane of the virtual surface, the pressing portion 20 moves relatively linearly in the rearward upward diagonal direction. To do. In this case, the first transmission unit 30a is pressed by the first tooth portion 24 of the pressing unit 20 and rotationally moves in the power generation rotation direction (clockwise rotation direction), so that the first transmission unit 30a and the first tooth The portion 24 converts the horizontal component force into a rotational force in the power generation rotation direction (clockwise rotation direction). Then, the rotational force in the converted power generation rotation direction (clockwise rotation direction) is transmitted to the rotation shaft of the dynamo in the power generation unit 80 by the first transmission unit 30a via the first shaft 50, the belt 60, and the second shaft 70. When it is transmitted to the dynamo, the rotating shaft of the dynamo is rotated by the transmitted rotational force, so that the dynamo can generate power.

Further, for example, as shown in FIG. 6, when the horizontal component force is no longer applied to the receiving portion 22 after the pressing portion 20 moves relatively linearly in the rearward upward diagonal direction, the pressing portion 20 As the weight drops, the pressing portion 20 moves in a relative linear direction in the forward downward diagonal direction. In this case, the second transmission portion 30b is pressed by the second tooth portion 25 of the pressing portion 20 and rotationally moves in the power generation rotation direction (clockwise rotation direction), so that the second transmission portion 30b and the second tooth The self-gravity of the pressing portion 20 is converted into a rotational force in the power generation rotation direction (clockwise rotation direction) by the portion 25. Then, the rotational force in the converted power generation rotation direction (clockwise rotation direction) is transmitted to the rotation shaft of the dynamo in the power generation unit 80 by the second transmission unit 30b via the first shaft 50, the belt 60, and the second shaft 70. When it is transmitted to the dynamo, the rotating shaft of the dynamo is rotated by the transmitted rotational force, so that the dynamo can generate power.

(Configuration-Other configurations)
In addition to this, the power generation system 1 can be configured with an arbitrary structure as much as possible. Specifically, in the first embodiment, the first transmission unit 30a and the second transmission unit 30b are formed so that the rotation speeds of the first transmission unit 30a and the second transmission unit 30b are substantially the same. I explained that, but it is not limited to this. For example, when the movement efficiency of the pressing unit 20 differs depending on the moving direction of the relative linear movement of the pressing unit 20, either one of the first transmission unit 30a or the second transmission unit 30b is the first transmission unit 30a or The first transmission unit 30a or the second transmission unit 30b may be formed so as to rotate at a lower speed or a higher speed than the other of the second transmission units 30b. As an example, when the movement efficiency when the pressing portion 20 moves relative linearly in the rearward upward diagonal direction is lower than the movement efficiency when the pressing portion 20 moves relative linearly in the forward downward diagonal direction. By making the diameter of the first transmission unit 30a smaller than the diameter of the second transmission unit 30b (or by changing the number of protrusions 40 of the first transmission unit 30a to the number of protrusions 40 of the second transmission unit 30b). The first transmission unit 30a may be formed as a high-speed rotation type ratchet gear, and the second transmission unit 30b may be formed as a low-speed rotation type ratchet gear. With such a configuration, when the movement efficiency of the pressing unit 20 differs depending on the moving direction of the relative linear movement of the pressing unit 20, the pressing is performed by changing the rotation speed of the first transmission unit 30a or the second transmission unit 30b. Since the movement efficiency of the unit 20 can be improved, the power generation efficiency of the power generation system 1 can be maintained.

Further, in the first embodiment, it has been described that the moving direction of the relative linear movement of the pressing portion 20 is the front-back, up-down, and diagonal directions, but the present invention is not limited to this, and may be, for example, the front-back direction along the horizontal direction. .. In this case, if the horizontal component force of the pressing portion 20 moves relatively linearly backward due to the horizontal component force of the wave and then the horizontal component force is no longer applied to the receiving portion 22, for example, the pressing portion 20 is moved to the original position. The pressing portion 20 may be relatively linearly moved forward by a known restoring means (for example, an elastic member such as a spring or rubber) for returning to the position.

Further, in the first embodiment, it has been explained that the pressing unit 20, the first transmission unit 30a, and the second transmission unit 30b are arranged so that the virtual surfaces are orthogonal to each other in the left-right direction (so-called vertical installation state). However, the present invention is not limited to this, and for example, the virtual surface may be arranged so as to be substantially horizontal (so-called horizontal arrangement).

Further, in the first embodiment, one set including the pressing unit 20, the first transmission unit 30a, the second transmission unit 30b, the first shaft 50, the belt 60, the second shaft 70, and the power generation unit 80 is provided. I explained that there is, but it is not limited to this. 8 and 9 are diagrams showing a modified example of the power generation system 1 according to the first embodiment. For example, as shown in FIG. 8, a plurality of the above sets may be provided in order to improve the amount of power generation. In this case, as shown in FIG. 8, each set of pressing portions 20 may include a receiving portion 22 and a connecting portion 23, respectively. The length of these connecting portions 23 in the front-rear direction is arbitrary, but for example, the length may be set according to the height of the water surface (so-called tide level), and as an example, the length corresponding to high tide. Set the height to be shorter than the length corresponding to the low tide. Alternatively, as shown in FIG. 9, a receiving portion 22 in which a plurality of sets of pressing portions 20 are common may be provided. Regarding the accommodating portion 10, in the modified example of FIG. 8, the accommodating portion 10 may be provided for each group, or the accommodating unit 10 common to a plurality of groups may be provided, but in the modified example of FIG. , The accommodating portion 10 common to a plurality of sets will be provided.

Further, in the first embodiment, it has been described that one set including the first transmission unit 30a, the second transmission unit 30b, and the first shaft 50 is provided for one pressing unit 20. Not limited. FIG. 10 is a diagram showing a modified example of the power generation system 1 according to the first embodiment. For example, as shown in FIG. 10, in order to improve the amount of power generation, a plurality of the above sets may be provided for one pressing portion 20. In this case, as shown in FIG. 10, a plurality of sets of the first transmission unit 30a, the second transmission unit 30b, and the first shaft 50 are arranged side by side in the front-rear direction. Further, a belt 60, a second shaft 70, and a power generation unit 80 are provided for each set.

Further, in the first embodiment, it has been described that one set including the first transmission unit 30a and the second transmission unit 30b is provided for one first shaft 50, but the present invention is not limited to this. FIG. 11 is a diagram showing a modified example of the power generation system 1 according to the first embodiment. For example, as shown in FIG. 11, a plurality of the above sets may be provided for one first shaft 50 (in the example of FIG. 11, three sets of the first transmission section 30a and the second transmission section 30b are provided. Has been). In this case, for example, the rotation speeds of the first transmission unit 30a and the second transmission unit 30b of each set are set to be different so that the pressing unit 20 can perform relative linear movement according to the wave condition. (As an example, the rotation speed of the first set is set to the highest speed, the rotation speed of the second set is set to the lowest speed, and the rotation speed of the third set is the rotation speed of the first set and the second set. Set to a speed intermediate to the rotation speed of). As a result, for example, when the wave height is relatively low, only the first transmission unit 30a and the second transmission unit 30b of the first group (or the first and second groups) can be rotated, and a typhoon or the like can be rotated. When the wave height is relatively high due to the influence, the first transmission unit 30a and the second transmission unit 30b of the first group, the second group, and the third group can be rotated, so that regardless of the wave condition. The relative linear movement of the pressing portion 20 can be performed at a constant speed, and the power generation efficiency of the power generation system 1 can be maintained. Alternatively, the rotation speed is not limited to this, and for example, the rotation speeds of the first transmission unit 30a and the second transmission unit 30b of each set may be set to be the same.

Further, in the first embodiment, it has been explained that the first transmission portion 30a and the second transmission portion 30b are provided as the transmission means, and the first tooth portion 24 and the second tooth portion 25 are provided as the tooth portions. However, it is not limited to this. 12 and 13 are diagrams showing a modified example of the power generation system 1 according to the first embodiment. For example, as shown in FIG. 12, as transmission means, in addition to the first transmission unit 30a and the second transmission unit 30b, the third transmission unit 30c (third transmission means) and the fourth transmission unit 30d (fourth transmission means). ) Is provided, and a third tooth portion 27 may be provided as a tooth portion in addition to the first tooth portion 24 and the second tooth portion 25.

The third transmission unit 30c is a transmission means for transmitting the rotational force in the power generation rotation direction, which will be described later, to the dynamo of the power generation unit 80, which will be described later, by rotating itself. Like the first transmission unit 30a, the third transmission unit 30c is configured by using a known ratchet gear or the like that can rotate only in the same direction as the power generation rotation direction, and as shown in FIG. 12, the first transmission unit 30c is configured. They are arranged at intervals from each of the 30a and the second transmission unit 30b (specifically, arranged on the left side of the first transmission unit 30a), and are arranged with respect to the first shaft 50 by a fixture or the like. It is fixed.

The fourth transmission unit 30d is a transmission means for rotating the third transmission unit 30c as the fourth transmission unit 30d rotates. The fourth transmission unit 30d is configured by using, for example, a known spur gear or the like, and is arranged at a position where it can come into contact with the third transmission unit 30c (specifically, on the lower side of the third transmission unit 30c). (Arranged in) and fixed to a shaft (not shown) rotatably fixed to the accommodating portion 10 by a fixture or the like.

The third tooth portion 27 is for pressing the fourth transmission portion 30d, includes a plurality of protrusions 26, and is arranged so as to be in contact with the fourth transmission portion 30d. Regarding the details of the installation method of the third tooth portion 27, for example, as shown in FIG. 12, the main body portion 21 has the fourth transmission portion 30d in addition to the first frame portion 21a to the fourth frame portion 21d. After the fifth frame portion 21e arranged on the side, the sixth frame portion (not shown) connecting the front side portion of the first frame portion 21a and the front side portion of the fifth frame portion 21e, and the rear of the first frame portion 21a. It includes a seventh frame portion (not shown) that connects the side portion and the rear side portion (not shown) of the fifth frame portion 21e. Then, among these frame portions, at the end portion of the horizontal bar portion of the fifth frame portion 21e on the side of the fourth transmission portion 30d, the third tooth portion 27 is aligned with the moving direction of the relative linear movement of the pressing portion 20. It is installed.

Here, regarding the shape of the protrusion 26 in each of the first tooth portion 24, the second tooth portion 25, and the third tooth portion 27, specifically, the receiving portion 22 receives a wave force or the like to press the pressing portion 26. When 20 is rotationally moved toward one of the rotation directions (clockwise rotation direction) in the in-plane rotation of the virtual surface, the first transmission portion 30a and the second transmission are transmitted by the first tooth portion 24 and the second tooth portion 25. When the portion 30b is pressed and rotates in the power generation rotation direction, and the pressing portion 20 rotates in the other direction (counterclockwise rotation direction) in the in-plane rotation of the virtual surface, the third tooth portion The third transmission unit 30c is pressed by the 27 through the fourth transmission unit 30d and is formed so as to rotate and move in the power generation rotation direction. More specifically, the shapes of the protrusions 26 of the first tooth portion 24 and the second tooth portion 25 are formed in the same shape as in the first embodiment. Regarding the shape of the protrusion 26 of the third tooth portion 27, the protrusion 26 of the third tooth portion 27 and the protrusion of the fourth transmission portion 30d are not related to the rotation direction in the in-plane rotation of the virtual surface of the pressing portion 20. By engaging with the portion 40, the third transmission portion 30c is pressed by the third tooth portion 27 via the fourth transmission portion 30d (even if the third transmission portion 30c is pressed, the third transmission portion 30c is pressed). Unless the internal ratchet of the transmission portion 30c meshes with the fourth transmission portion 30d, the third transmission portion 30c does not rotate), and is formed in a substantially regular triangular shape protruding upward.

With such a structure, when the pressing unit 20 rotates and moves regardless of the rotation direction in the in-plane rotation of the virtual surface, the pressing unit 20 causes the first transmission unit 30a, the second transmission unit 30b, or the third transmission unit 20 to rotate. 30c can be pressed so as to rotate and move in the power generation rotation direction. Therefore, as compared with the case where the third transmission unit 30c, the fourth transmission unit 30d, and the third tooth portion 27 are not provided, it is possible to generate power regardless of the rotation direction in the in-plane rotation of the virtual surface of the pressing unit 20. Therefore, the amount of power generation can be increased. Further, according to the shape of the protrusion 26 of the third tooth portion 27, when the pressing portion 20 moves relatively linearly in the rearward upward diagonal direction, the third transmission portion 30c is the third tooth portion 27. Although it is pressed via the fourth transmission unit 30d, the internal ratchet of the third transmission unit 30c and the fourth transmission unit 30d do not mesh with each other, so that the ratchet can idle. On the other hand, when the pressing portion 20 moves relatively linearly in the forward downward oblique direction, the third transmission portion 30c is pressed by the third tooth portion 27 via the fourth transmission portion 30d, and the third transmission portion 30c is pressed. The internal ratchet of the transmission unit 30c and the fourth transmission unit 30d mesh with each other to rotate in the power generation rotation direction.

In the modified example of FIG. 12, it has been explained that one fourth transmission unit 30d that can come into contact with the third transmission unit 30c is provided, but the present invention is not limited to this. For example, a plurality of fourth transmission units 30d may be provided on the periphery of the third transmission unit 30c. As a result, when the angle of in-plane rotation of the virtual surface in the pressing unit 20 is relatively small, the third transmission unit 30c and a part of the plurality of fourth transmission units 30d are brought into contact with each other, and the virtual surface in the pressing unit 20 When the angle of in-plane rotation is relatively large, the third transmission unit 30c can be brought into contact with the other part of the plurality of fourth transmission units 30d. Therefore, regardless of the magnitude of the in-plane rotation angle of the virtual surface in the pressing portion 20, the third transmission portion 30c can be pressed by the third tooth portion 27 via the fourth transmission portion 30d. Further, in the modified example of FIG. 12, it has been explained that one set including the third transmission portion 30c, the fourth transmission portion 30d, and the third tooth portion 27 is provided, but the present invention is not limited to this. For example, a plurality of the above sets may be provided. As an example, as shown in FIG. 13, in the power generation system 1 of FIG. 12, one further set is additionally provided on the right side of the second transmission unit 30b. You may. In this case, in order to stably perform the relative linear movement of the pressing portion 20, the fourth transmission portion 30d of the added set is arranged below the third tooth portion 27 of the added set. At the same time, the third transmission unit 30c of the added set may be arranged below the fourth transmission unit 30d of the added set. Further, the shape of the protrusion 26 of the third tooth portion 27 of the added set may be formed in a substantially regular triangular shape protruding downward.

Further, in the first embodiment, it has been described that the internal shapes of the first accommodating portion 11 and the second accommodating portion 12 of the accommodating portion 10 are formed in an elliptical ring shape, but the present invention is not limited to this, and various shapes can be obtained. May be formed. FIG. 14 is a diagram showing a modified example of the accommodating portion 10 according to the first embodiment. For example, as shown in FIG. 14, the internal shape of the first accommodating portion 11 is a rectangular ring with an open upper surface (specifically, a rectangular annulus longer than the vertical length of the inner diameter of the first accommodating portion 11). Or, the internal shape of the second accommodating portion 12 is formed into a rectangular annulus having an open upper surface (specifically, a rectangular annulus having substantially the same inner diameter as the inner diameter of the land side end of the first accommodating portion 11). May be formed.

(effect)
As described above, according to the first embodiment, the pressing unit 20, the first transmission unit 30a, or the first transmission unit 30a is provided in the plane of the virtual surface orthogonal to the rotation center axis of each of the first transmission unit 30a and the second transmission unit 30b. When a wave force (external force) is applied to the second transmission unit 30b, the first transmission unit 30a, the second transmission unit 30b, and the pressing unit 20 move relatively linearly along the virtual surface. Therefore, the pressing portion 20 is formed so that either the first transmitting portion 30a or the second transmitting portion 30b is pressed and rotationally moved by the pressing portion 20, and the dynamos of the power generation unit 80 are relative to each other. When the target linear movement is a movement in one of the relative linear movements, the rotation axis is rotated by the rotational force transmitted by the first transmission unit 30a to generate power, and the relative movement is performed. When the linear movement is a movement in the other movement direction of the relative linear movement, the rotation axis is rotated by the rotational force transmitted by the second transmission unit 30b to generate power. Since the transmission unit 30a and the second transmission unit 30b can be composed of parts (specifically, a known ratchet gear or the like) on the market, it is not necessary to configure the transmission unit 30a and the second transmission unit 30b with a special structure. It is possible to improve the manufacturability of the system 1 and reduce the manufacturing cost.

Further, when the relative linear movement is a movement in one of the relative linear movement directions, the first transmission portion 30a is pressed by the first tooth portion 24 to rotate and move in the power generation rotation direction. When the relative linear movement is a movement in the other movement direction of the relative linear movement, the second transmission portion 30b is pressed by the second tooth portion 25 to rotate in the power generation rotation direction. Since the first tooth portion 24 and the second tooth portion 25 are formed, it is not necessary to provide an adjusting means for adjusting the rotation direction of the first transmission portion 30a or the second transmission portion 30b so as to coincide with the power generation rotation direction. Therefore, it is possible to reduce the manufacturing cost of the power generation system 1.

Further, the pressing portion 20 is a main body portion 21 having a first tooth portion 24 and a second tooth portion 25 and a receiving portion 22 located below the main body portion 21, and receives a horizontal component of wave force. A receiving portion 22 and a connecting portion 23 connecting the main body portion 21 and the receiving portion 22 are provided, and a horizontal component force is applied to the receiving portion 22 when the relative linear movement is in the vertical and diagonal directions. If this is the case, either the first tooth portion 24 or the second tooth portion 25 is formed by the pressing portion 20 linearly moving in the upward diagonal direction, which is one of the relative linear movement movement directions. Either one of the first transmission section 30a and the second transmission section 30b is pressed by one of them to rotate and move, and after the pressing section 20 moves linearly in the upward oblique direction, a horizontal component force is applied to the receiving section 22. When it disappears, the pressing portion 20 moves linearly in the downward oblique direction, which is the other direction of the relative linear movement, as the pressing portion 20 lowers its own weight, so that the first tooth The first transmission unit 30a and the second transmission unit 30a so that either the first transmission unit 30a or the second transmission unit 30b is pressed and rotationally moved by either the portion 24 or the second tooth portion 25. Since 30b and the pressing portion 20 are installed, when the pressing portion 20 moves in a relative linear direction in the vertical and diagonal directions, power can be generated by utilizing the wave force and the own weight of the pressing portion 20, and the wave force can be generated. Compared with the case where power is generated using only the power generation system 1, it is possible to reliably generate power of the power generation system 1 regardless of the moving direction of the relative linear movement.

Further, when the pressing portion 20 moves relatively linearly in the upward diagonal direction, wave water flows into the inside of the receiving portion 22, and when the pressing portion 20 moves relatively linearly in the downward diagonal direction, it flows in. Since the receiving portion 22 is formed so that the made water flows out to the outside of the receiving portion 22, the pressing portion 20 is relatively linearly moved downward by the weight of the water flowing into the receiving portion 22. The relative linear movement of the pressing portion 20 can be reliably performed as compared with the case where the receiving portion 22 is formed so that the water of the wave does not flow into the receiving portion 22.

Further, the internal shape of the accommodating portion 10 is a shape capable of promoting the relative linear movement of the pressing portion 20 by amplifying the internal water level of the accommodating portion 10 by the wave flowing into the accommodating portion 10. As compared with the case where the internal shape of the accommodating portion 10 is made uniform, the internal water level of the accommodating portion 10 can be amplified when a wave flows into the inside of the accommodating portion 10, and the inflow is described above. The internal water level of the accommodating portion 10 can be rapidly lowered when the generated wave flows out of the accommodating portion 10. Therefore, the relative linear movement of the pressing portion 20 can be effectively performed, and the amount of power generated by the power generation system 1 can be increased.

[Embodiment 2]
Next, the second embodiment will be described. This form is different from the first embodiment, and is a form in which power generation is performed by utilizing the horizontal component of wave power. The components substantially the same as those in the first embodiment will be given the same reference numerals or names as those used in the first embodiment, and the description thereof will be omitted as necessary.

(Constitution)
First, the configuration of the power generation system according to the second embodiment will be described. FIG. 15 is an enlarged right side view showing the power generation system according to the second embodiment, and is a diagram showing a region corresponding to FIG. FIG. 16 is a right side view showing a state in which the pressing portion moves relative to the transmitting portion in an obliquely rearward upward direction. FIG. 17 is a right side view showing a state in which the pressing portion moves relative to the transmitting portion in a diagonally forward and downward direction. As shown in FIG. 15, the power generation system 100 according to the second embodiment includes an accommodating portion (not shown), a pressing portion 20, a transmitting portion 90, a first shaft (not shown), a belt (not shown), and a second shaft. It is equipped with a power generation unit (not shown) and a power generation unit (not shown).

(Structure-Transmission part, 1st shaft)
The transmission unit 90 is configured by using, for example, a known gear or the like having a plurality of protrusions 91, and is fixed to the first shaft by a fixture or the like. Further, the first shaft is for transmitting the rotational force transmitted from the transmission unit 90 to the belt, and as shown in FIG. 15, the first shaft is installed so that the longitudinal direction of the first shaft is along the left-right direction. There is.

(Structure-Pressing part)
The pressing portion 20 includes a main body portion (not shown), a receiving portion (not shown), and a connecting portion (not shown). Of these, the main body portion is formed in a rectangular annular shape having a relatively thick side surface shape (that is, an accommodating hole 28 is formed inside the main body portion). Here, regarding the shape of the accommodating hole 28, in the second embodiment, the transmitting portion 90 can be accommodated in the accommodating hole 28, and the horizontal component force of the wave force is contained in the pressing portion 20 in the plane of the virtual surface. Is added, and when the pressing portion 20 moves relatively linearly, it is formed in a shape capable of securing a predetermined movement amount (so-called stroke). Specifically, as shown in FIG. 15, the length of the accommodation hole 28 in the longitudinal direction (substantially the front-rear direction) is longer than the length of the transmission portion 90 in the front-rear direction (for example, the length of the transmission portion 90 in the front-rear direction). The length of the accommodating hole 28 in the lateral direction (substantially in the vertical direction) is substantially the same as the length in the vertical direction of the transmission portion 90.

Further, a first tooth portion 24 is provided on the upper end side of the accommodating hole 28 in the main body portion, and a second tooth portion 25 is provided on the lower end side of the accommodating hole 28 in the main body portion. Specifically, the first tooth portion 24 and the second tooth portion 25 are in contact with the transmission portion 90 and are arranged so as to follow the moving direction of the relative linear movement. Here, the shape of the protrusion 26 in each of the first tooth portion 24 and the second tooth portion 25 is arbitrary, but in the second embodiment, as shown in FIG. 16, the pressing portion 20 is in the upward oblique direction. (Specifically, when the relative linear movement is performed in the rearward and upward diagonal direction), the transmission portion 90 is pressed by the first tooth portion 24 and rotationally moves in the power generation rotation direction, as shown in FIG. When the pressing portion 20 moves relatively linearly in the downward diagonal direction (specifically, the front downward diagonal direction), the transmission portion 90 is pressed by the second tooth portion 25 and rotationally moves in the power generation rotation direction. It is formed in. Specifically, regarding the shape of the protrusion 26 of the first tooth portion 24, the protrusion 26 of the first tooth portion 24 is rearward and downward, substantially the same as the shape of the first tooth portion 24 according to the first embodiment. It is formed in a shape that inclines and protrudes toward. Further, regarding the shape of the protrusion 26 of the second tooth portion 25, the protrusion 26 of the second tooth portion 25 is inclined toward the front upper side in substantially the same manner as the shape of the second tooth portion 25 according to the first embodiment. It is formed in a protruding shape. Due to such a shape, when the pressing portion 20 moves in a relative linear motion, the transmitting portion 90 can be pressed so as to rotate and move in the power generation rotation direction by the pressing portion 20 regardless of the moving direction of the relative linear movement. Since it is not necessary to provide an adjusting unit for adjusting the rotation direction of the transmission unit 90 so as to coincide with the power generation rotation direction, it is possible to reduce the manufacturing cost of the power generation system 100.

(Structure-Details of installation position of pressing part and transmission part)
Next, the installation positions of the pressing unit 20 and the transmitting unit 90 will be described. Regarding the details of the installation positions of the pressing portion 20 and the transmitting portion 90, in the second embodiment, as shown in FIG. 16, the horizontal component force of the wave is added to the receiving portion (not shown) in the plane of the virtual surface. In this case, the pressing portion 20 moves in a relative linear direction in the upward diagonal direction (specifically, the rearward upward diagonal direction), so that the transmission portion 90 is pressed by the main body portion (not shown) and rotates. After moving and, as shown in FIG. 17, when the horizontal component force is no longer applied to the receiving portion after the pressing portion 20 moves relatively linearly in the upward diagonal direction, the weight of the pressing portion 20 drops. Along with this, the pressing portion 20 moves relatively linearly in the downward diagonal direction (specifically, the front downward diagonal direction) so that the transmitting portion 90 is pressed by the main body portion and rotates. 20 and a transmission unit 90 are arranged. Specifically, as shown in FIG. 15, in a state where the transmission portion 90 is accommodated along the virtual surface inside the accommodation hole 28 of the main body portion, the protrusion 91 and the first tooth portion 24 of the transmission portion 90 are accommodated. And each of the protrusions 26 of the second tooth portion 25 is provided so as to be in contact with each other.

With the structure of the power generation system 100 as described above, the horizontal component force required for power generation can be obtained even when the power generation system 100 is installed on land (breakwater), substantially similar to the power generation system 1 according to the first embodiment. It is possible to generate a desired amount of power using the horizontal component force.

(Configuration-Power generation system function)
The function of the power generation system 100 configured in this way will be described.

First, for example, as shown in FIG. 16, when a horizontal component force of a wave is applied to the receiving portion 22 in the plane of the virtual surface, the pressing portion 20 moves in a relative linear direction in the rearward upward diagonal direction. To do. In this case, the transmission unit 90 is pressed by the first tooth portion 24 of the pressing portion 20 and rotationally moves in the power generation rotation direction (clockwise rotation direction), so that the transmission unit 90 and the first tooth portion 24 describe the above. The horizontal component force is converted into the rotational force in the power generation rotation direction (clockwise rotation direction).

Since the detailed setting of the attenuation constant may differ depending on the weights of the first transmission unit and the second transmission unit 30b and the like, it may be set based on, for example, experimental results.

With the structure of the power generation system 400 as described above, even when the power generation system 400 is installed offshore, the vertical component force required for power generation can be obtained. Therefore, the same as the power generation system according to the third and fourth embodiments. , The desired amount of power generation can be generated by using the vertical component force.

(Configuration-Power generation system function)
The function of the power generation system 400 configured in this way will be described.

First, for example, when a vertical component of wave power is applied to the floating body portion 130, the first transmission portion and the second transmission portion 30b are pulled up by the spring portion 131, so that the first transmission portion and the second transmission portion and the second are The transmission unit 30b moves relatively linearly upward. In this case, the first transmission portion is pressed by the first tooth portion 24 of the pressing portion 20 and rotationally moves in the power generation rotation direction (clockwise rotation direction), whereby the first transmission portion and the first tooth portion 24 The vertical component force is converted into a rotational force in the power generation rotation direction (clockwise rotation direction). Then, the rotational force in the converted power generation rotation direction (clockwise rotation direction) is transmitted to the rotation shaft of the dynamo in the power generation unit by the first transmission unit via the first shaft 50, the belt, and the second shaft. Then, the rotating shaft of the dynamo rotates due to the transmitted rotational force, so that the dynamo can generate power.

Further, for example, when the vertical component force is no longer applied to the floating body portion 130 after the first transmission unit and the second transmission unit 30b move in a relative linear direction upward, the first transmission unit and the first transmission unit and the first transmission unit 30b are not applied. 2 As the weight of the transmission unit 30b drops, the first transmission unit and the second transmission unit 30b move in a relative linear direction downward. In this case, the second transmission portion 30b is pressed by the second tooth portion 25 of the pressing portion 20 and rotationally moves in the power generation rotation direction (clockwise rotation direction), so that the second transmission portion 30b and the second tooth The self-gravity of the pressing portion 20 is converted into a rotational force in the power generation rotation direction (clockwise rotation direction) by the portion 25. Then, the rotational force in the converted power generation rotation direction (clockwise rotation direction) is transmitted to the rotation shaft of the dynamo in the power generation unit by the second transmission unit 30b via the first shaft 50, the belt, and the second shaft. Then, the rotating shaft of the dynamo is rotated by the transmitted rotational force, so that the dynamo can generate power.

(Configuration-Other configurations)
In addition to this, the power generation system 400 can be configured with an arbitrary structure as much as possible. Specifically, in the fifth embodiment, the first transmission portion and the second transmission portion 30b are connected to the upper end portion of the floating body portion 130 via the spring portion 131 and the connecting portion 134, and the pressing portion 20 is the floating body portion. It has been explained that it is connected to the lower end of the 130, but the present invention is not limited to this. 26 to 28 are views showing a modified example of the power generation system 400 according to the fifth embodiment. For example, as shown in FIG. 26, the first transmission portion and the second transmission portion 30b are connected to the lower end portion of the floating body portion 130 via the spring portion 131 and the connection portion 134, and the pressing portion 20 is the upper end portion of the floating body portion 130. May be connected to. Alternatively, as shown in FIG. 27, the first transmission portion and the second transmission portion 30b are connected to the right end portion of the floating body portion 130 via the spring portion 131 and the connection portion 134, and the pressing portion 20 is connected to the left end portion of the floating body portion 130. May be connected to. Alternatively, as shown in FIG. 28, the first transmission portion and the second transmission portion 30b are connected to the right end portion of the floating body portion 130 via the spring portion 131 and the connecting portion 134, and the pressing portion 20 is the lower end portion of the floating body portion 130. May be connected to.

Further, in the fifth embodiment, the floating body portion 130 includes a pressing portion 20, a first transmission portion, a second transmission portion 30b, a first shaft 50, a belt, a second shaft, a power generation portion, and a spring portion 131. I explained that one set is contained, but it is not limited to this. FIG. 29 is a diagram showing a modified example of the power generation system 400 according to the fifth embodiment. For example, as shown in FIG. 29, a plurality of the above sets may be provided. Further, as shown in FIG. 29, the connection positions of the first transmission unit, the second transmission unit 30b, and the pressing unit 20 of each set may be different, or may be the same connection position.

(effect)
As described above, according to the fifth embodiment, when the moving direction of the relative linear movement is the vertical direction and the vertical component force is applied to the floating body portion 130, the spring portion 131 causes the first transmission portion. And by pulling up the second transmission unit 30b, the first transmission unit and the second transmission unit 30b linearly move upward, which is one of the movement directions of the relative linear movement, so that the first transmission unit and the second transmission unit 30b move linearly. Either the first transmission portion or the second transmission portion 30b is pressed by either the tooth portion 24 or the second tooth portion 25 to rotate and move, and the pressing portion 20 linearly moves upward and then vertically. When the directional component force is no longer applied to the floating body portion 130, the first transmission portion and the second transmission portion 30b move in a relative linear line as the weight of the first transmission portion and the second transmission portion 30b drops. By linearly moving downward, which is the other direction of the movement direction, either the first tooth portion 24 or the second tooth portion 25 is used, and either the first transmission portion or the second transmission portion 30b is used. Since the first transmission unit, the second transmission unit 30b, and the pressing unit 20 are installed so that the power generation system 400 is pressed and rotates, even if the power generation system 400 is installed offshore, the vertical direction required for power generation is required. Since the component force can be obtained, it is possible to generate a desired amount of power by using the vertical component force as in the power generation system according to the third and fourth embodiments.

[Embodiment 6]
Next, the sixth embodiment will be described. This form is different from the third to fifth embodiments, and is a form in which power is generated by utilizing the vertical component force of the wave power. The components substantially the same as those in the first embodiment will be given the same reference numerals or names as those used in the first embodiment, and the description thereof will be omitted as necessary.

(Constitution)
First, the configuration of the power generation system according to the sixth embodiment will be described.

(Not shown), a second shaft (not shown), a power generation unit (not shown), a second floating body portion 141, and two sets including a connecting portion 142 are provided.

(Structure-1st floating body part)
The first floating body portion 140 is such that at least a part of the first floating body portion 140 can float on the water surface. The first floating body portion 140 is formed of a substantially U-shaped hollow body, and specifically, as shown in FIG. 30, the first accommodating portion 140a (a substantially U-shaped vertical bar portion). One), a second accommodating portion 140b (the other of the substantially U-shaped vertical bar portions), and a third accommodating portion 140c (a substantially U-shaped horizontal bar portion).

The first accommodating portion 140a receives the vertical component force of the wave force while accommodating one of the above two sets. Further, the second accommodating portion 140b receives the vertical component force of the wave force while accommodating the other pair of the above two sets. As shown in FIG. 30, the first accommodating portion 140a and the second accommodating portion 140b are long hollow bodies formed of, for example, a metal material, a resin material, or the like, and at least a part thereof floats on the water surface. It is formed to do. Further, openings (not shown) are formed at the lower ends of the first accommodating portion 140a and the second accommodating portion 140b. The opening is an opening for taking in the liquid (for example, water or the like) contained in the third accommodating portion 140c into the first accommodating portion 140a or the second accommodating portion 140b.

The third accommodating portion 140c is for connecting the first accommodating portion 140a and the second accommodating portion 140b. As shown in FIG. 30, the third accommodating portion 140c is, for example, a long tubular body formed of a known elastic member (resin material or the like as an example), and specifically, the third accommodating portion 140c. The length in the longitudinal direction of is set to about half of the wavelength of the wave. Further, openings (not shown) are formed at both ends of the third accommodating portion 140c in the longitudinal direction. The opening is an opening for a liquid (for example, water or the like) contained in the third accommodating portion 140c to flow in or out of the first accommodating portion 140a or the second accommodating portion 140b.

The method of forming the first floating body portion 140 is arbitrary, but in the embodiment, one end of the third accommodating portion 140c in the longitudinal direction and the lower end portion of the first accommodating portion 140a are connected by a fixture or the like. At the same time, the other end of the third accommodating portion 140c in the longitudinal direction and the lower end portion of the second accommodating portion 140b are connected by a fixture or the like, and the liquid is accommodated in the first floating body portion 140 before and after these connections. It is formed by.

(Structure-Pressing part)
As shown in FIG. 30, the pressing portion 20 includes a main body portion 21 (however, excluding the third frame portion 21c). As shown in FIG. 30, the main body 21 is arranged so that the longitudinal direction of the first frame 21a (or the second frame 21b) is substantially along the vertical direction, and the upper end of the main body 21 is the first. It is fixed to the upper end of the accommodating portion 140a or the second accommodating portion 140b by a fixture, welding, or the like.

(Structure-2nd floating body part)
The second floating body portion 141 is such that at least a part of the second floating body portion 141 can float on the water surface, and the first transmitting portion, the second transmitting portion 30b, and the first shaft via the connecting portion 142. It supports 50. The second floating body portion 141 is, for example, a substantially box-shaped body (for example, a rectangular parallelepiped) formed of a metal material, a resin material, wood, or the like, is located below the main body portion 21, and is a first floating body portion. It floats on the liquid surface housed in 140 in a state where it can swing in the vertical direction.

(Configuration-Connection)
The connecting portion 142 connects the first transmitting portion and the second transmitting portion 30b to the second floating body portion 141, and is formed of a long substantially rod-shaped body. Here, the method of connecting the first transmission section and the second transmission section 30b by the connection section 142 to the second floating body section 141 is arbitrary, but in the sixth embodiment, first, the first transmission section and the second transmission section are used. After the portions 30b are arranged side by side in the left-right direction at intervals from each other, the first transmission portion and the second transmission portion 30b are fixed to the first shaft 50 by a fixture or the like. Then, one of the longitudinal ends of the connecting portion 142 is connected to the first shaft 50 by a rotatable fixture or the like (for example, a ball bearing or the like), and the longitudinal end portion of the connecting portion 142 is connected. The other of the above is connected to the second floating body portion 141 by a fixture or the like.

With the structure of the power generation system 500 as described above, even when the power generation system 500 is installed offshore, the vertical component force required for power generation can be obtained. Therefore, the same as the power generation system according to the third to fifth embodiments. , The desired amount of power generation can be generated by using the vertical component force.

(Configuration-Power generation system function)
The function of the power generation system 500 configured in this way will be described.

First, for example, when the vertical component of the wave power is applied to either the first accommodating portion 140a or the second accommodating portion 140b of the first floating body portion 140, the first accommodating portion 140a and the second accommodating portion 140a are applied. While the third accommodating portion 140c of the first floating body portion 140 is deformed so that the levels of the second floating body portion 141 accommodated in the portion 140b are substantially the same (note that, with this deformation, the first accommodating portion 140a and The distance between the first accommodating portion 140a and the second accommodating portion 140b is shortened), and the first transmitting portion and the second transmitting portion 30b accommodated in either the first accommodating portion 140a or the second accommodating portion 140b move relatively linearly. Relative linear movement toward the upward direction, which is one of the moving directions of. In this case, the first transmission portion is pressed by the first tooth portion 24 of the pressing portion 20 and rotationally moves in the power generation rotation direction (clockwise rotation direction), whereby the first transmission portion and the first tooth portion 24 The vertical component force is converted into a rotational force in the power generation rotation direction (clockwise rotation direction). Then, the rotational force in the converted power generation rotation direction (clockwise rotation direction) is transmitted to the rotation shaft of the dynamo in the power generation unit by the first transmission unit via the first shaft 50, the belt, and the second shaft. Then, the rotating shaft of the dynamo rotates due to the transmitted rotational force, so that the dynamo can generate power.

Further, for example, after the first transmission unit and the second transmission unit 30b move relatively linearly upward, the vertical component force is applied to either the first accommodation portion 140a or the second accommodation portion 140b. When it disappears, while deforming the first floating body portion 140 so that the levels of the second floating body portions 141 housed in the first accommodating portion 140a and the second accommodating portion 140b are substantially the same (note that this deformation occurs). As a result, the distance between the first accommodating portion 140a and the second accommodating portion 140b returns to the original length), and the first transmitting portion and the second transmitting portion 30b are lowered by their own weight. And the second transmission unit 30b moves relatively linearly downward. In this case, the second transmission portion 30b is pressed by the second tooth portion 25 of the pressing portion 20 and rotationally moves in the power generation rotation direction (clockwise rotation direction), so that the second transmission portion 30b and the second tooth The self-gravity of the pressing portion 20 is converted into a rotational force in the power generation rotation direction (clockwise rotation direction) by the portion 25. Then, the rotational force in the converted power generation rotation direction (clockwise rotation direction) is transmitted to the rotation shaft of the dynamo in the power generation unit by the second transmission unit 30b via the first shaft 50, the belt, and the second shaft. Then, the rotating shaft of the dynamo is rotated by the transmitted rotational force, so that the dynamo can generate power.

(Configuration-Other configurations)
In addition to this, the power generation system 500 can be configured with an arbitrary structure as much as possible. Specifically, in the sixth embodiment, it has been described that the first floating body portion 140 includes a first accommodating portion 140a, a second accommodating portion 140b, and a third accommodating portion 140c, but the present invention is not limited thereto. .. FIG. 31 is a diagram showing a modified example of the power generation system 500 according to the sixth embodiment. For example, as shown in FIG. 31, the first floating body portion 140 may further include a ventilation opening 143. The ventilation opening 143 is an opening for taking in and out air inside and outside the first floating body portion 140, and is formed in each of the first accommodating portion 140a and the second accommodating portion 140b as shown in FIG. There is. In this case, as shown in FIG. 31, as a configuration for suppressing the inflow of water into the first floating body portion 140 through the ventilation opening 143, the ventilation opening 143 is provided in the first accommodation portion 140a. And may be arranged near the upper end of each of the second accommodating portions 140b. Further, a cover portion 144 that covers a part of the ventilation opening 143 from the outside may be provided in the vicinity of the ventilation opening 143 in each of the first accommodation portion 140a and the second accommodation portion 140b. With such a configuration, the relative linear movement of the first transmission unit and the second transmission unit 30b can be smoothly performed, and the power generation efficiency of the power generation system 500 can be improved.

Further, in the sixth embodiment, the first floating body portion 140 is located between the first accommodating portion 140a and the second accommodating portion 140b when the first transmitting portion and the second transmitting portion 30b move relatively linearly. I explained that the distance is configured to fluctuate, but it is not limited to this. 32 and 33 are views showing a modified example of the power generation system 500 according to the sixth embodiment. For example, as shown in FIG. 32, the first floating body portion 140 may further include a communication portion 145 that communicates the first accommodating portion 140a and the second accommodating portion 140b. The communication portion 145 is a long tubular body, and is connected to each of the first accommodating portion 140a and the second accommodating portion 140b so as to communicate with the upper end portion. The specific configuration of the communication portion 145 is arbitrary, but for example, in the communication portion 145, both end portions in the longitudinal direction and their vicinity are formed of a stretchable material (resin material or the like as an example). Or other parts may be formed of a material that cannot be expanded or contracted (for example, a metal material, a resin material, etc.). In this case, the specific configuration of the second accommodating portion 140b is arbitrary, but for example, it may be formed with substantially the same configuration as the communication portion 145. Alternatively, as shown in FIG. 33, the first floating body portion 140 may further include a pair of tension portions 146 in addition to the ventilation opening portion 143 and the cover portion 144 described above. The pair of tension portions 146 are for maintaining a distance between the first accommodating portion 140a and the second accommodating portion 140b. As shown in FIG. 33, the pair of tension portions 146 are arranged side by side with each other at intervals in the vertical direction between the first accommodating portion 140a and the second accommodating portion 140b. Each of the first accommodating portion 140a and the second accommodating portion 140b is connected by a rotatable fixture or the like (for example, a ball bearing or the like). With these configurations, when the first transmission unit and the second transmission unit 30b move relatively linearly, it is possible to prevent the distance between the first accommodation portion 140a and the second accommodation portion 140b from fluctuating. It is possible to adjust the amount of deformation of the third accommodating portion 140c.

Further, in the sixth embodiment, it has been explained that the first floating body portion 140 includes the first accommodating portion 140a and the second accommodating portion 140b as a portion accommodating the above-mentioned set, but the present invention is not limited to this. FIG. 34 is a plan view showing a modified example of the power generation system 500 according to the sixth embodiment. For example, as shown in FIG. 34, the first floating body portion 140 may further include a fourth accommodating portion 140d and an accommodating cover portion 147. The fourth accommodating portion 140d is for accommodating the above set, for example, is formed in substantially the same configuration as the first accommodating portion 140a, and is connected to the third accommodating portion 140c by a fixture or the like. ing. The accommodating cover portion 147 is for covering the first accommodating portion 140a, the second accommodating portion 140b, and the fourth accommodating portion 140d in order to improve the durability and weather resistance of the first floating body portion 140. The first accommodating portion 140a, the second accommodating portion 140b, and the fourth accommodating portion 140d are connected by a fixture or the like. With such a configuration, it is possible to increase the amount of power generated by the power generation system 500 while maintaining the durability and weather resistance of the first floating body portion 140.

Further, in the sixth embodiment, it has been explained that the power generation system 500 is installed offshore, but the present invention is not limited to this. FIG. 35 is a diagram showing a modified example of the power generation system 500 according to the sixth embodiment. For example, as shown in FIG. 35, the power generation system 500 may be installed near the quay of the port, and may further include a collecting unit 150. The collecting unit 150 is a collecting means for collecting waves, and has a first paraboloid 151 (35 in the figure is a first paraboloid having an opening facing offshore). It includes a second paraboloid 152 (second paraboloid) having a second paraboloid (in FIG. 35, a second paraboloid having an opening facing the land side). .. Regarding the details of the configurations of the first reflecting portion 151 and the second reflecting portion 152, specifically, as shown in FIG. 35, the opening diameter of the first paraboloid is the opening of the second paraboloid. It is set larger than the diameter so that the first paraboloid and the second paraboloid face each other (more specifically, the focal point of the first paraboloid and the focal point of the second paraboloid). The first reflecting unit 151 and the second reflecting unit 152 are arranged so as to match with). Further, the details of the installation of the first floating body portion 140 are specifically arranged between the first reflecting portion 151 and the second reflecting portion 152, as shown in FIG. 35, and are more specific. Is arranged at a position where the focal point of the first paraboloid and the focal point of the second paraboloid coincide with each other. With such a configuration, as compared with the case where a wave other than the wave collected between the first reflecting portion 151 and the second reflecting portion 152 is used, the first floating body portion 140 due to the amplification of the water level between the two. Since the first transmission unit or the second transmission unit 30b can be effectively pressed by the pressing unit 20 housed in the power generation system 500, the amount of power generated by the power generation system 500 can be increased. Further, by installing a plurality of collection units 150 for accommodating the first floating body unit 140 near the quay, the waves can be reduced (attenuated) by the collection unit 150, so that the waves around the port can be calmed down. .. The collecting unit 150 is not limited to being provided in the power generation system 500 according to the sixth embodiment, and may be provided in, for example, the power generation system according to the first to fifth embodiments.

(effect)
As described above, according to the sixth embodiment, when the moving direction of the relative linear movement is the vertical direction, the vertical component force of the wave force is applied to either the first accommodating portion 140a or the second accommodating portion 140b. In this case, while deforming the first floating body portion 140 so that the levels of the second floating body portions 141 accommodated in each of the first accommodating portion 140a and the second accommodating portion 140b are substantially the same, the first accommodating portion 140 The first transmission unit and the second transmission unit 30b accommodated in one of the portion 140a or the second accommodation portion 140b linearly move upward, which is one of the movement directions of the relative linear movement. Either the first tooth portion 24 or the second tooth portion 25 of the pressing portion 20 presses either the first transmission portion or the second transmission portion 30b to rotate and move, and the first accommodating portion 140a or After the first transmission unit and the second transmission unit 30b accommodated in one of the second accommodation portions 140b move linearly upward, the vertical component force is applied to either the first accommodation portion 140a or the second accommodation portion 140b. When it is no longer added to, the first floating body portion 140 is deformed so that the levels of the second floating body portions 141 housed in each of the first accommodating portion 140a and the second accommodating portion 140b are substantially the same. As the weight of the first transmission unit and the second transmission unit 30b drops, the first transmission unit and the second transmission unit 30b are directed downward, which is the other direction of the relative linear movement. By moving linearly, either the first tooth portion 24 or the second tooth portion 25 of the pressing portion 20 presses either the first transmission portion or the second transmission portion 30b to rotate and move. As described above, since the first transmission unit, the second transmission unit 30b, and the pressing unit 20 are installed, for example, even when the power generation system 500 is installed offshore, the vertical component force required for power generation can be obtained. Therefore, it is possible to generate a desired amount of power by using the vertical component force as in the power generation system according to the third to fifth embodiments.

(Effect of appendix)
According to the power generation system described in Appendix 1, the pressing means, the first transmitting means, or the second transmitting means in the plane of the virtual surface orthogonal to the rotation center axis of each of the first transmitting means and the second transmitting means. When an external force is applied to the means, the first transmitting means, the second transmitting means, and the pressing means move relatively linearly along the virtual surface, so that the pressing means causes the first transmitting means. Alternatively, the pressing means is formed so that one of the second transmitting means is pressed and rotationally moved, and the power generating means moves the relative linear movement toward one of the linear movements. In the case where the rotation axis is rotated by the rotational force transmitted by the first transmission means to generate power, and the relative linear movement is the movement in the other movement direction of the linear movement. In addition, since the rotating shaft is rotated by the rotational force transmitted by the second transmission means to generate power, the first transmission means and the second transmission means are distributed on the market (for example, ratchet gear, etc.). Since it is not necessary to configure it with a special structure, it is possible to improve the manufacturability of the power generation system and reduce the manufacturing cost.

According to the power generation system described in Appendix 2, when the relative linear movement is a movement in one of the linear movement directions, the first tooth portion presses the first transmission means to generate power. When the rotation moves in the rotation direction and the relative linear movement is the movement in the other movement direction of the linear movement, the second transmission means is pressed by the second tooth portion and rotates in the power generation rotation direction. Since the first tooth portion and the second tooth portion are formed so as to move, when the pressing means moves relatively linearly, the first transmission is performed by the pressing means regardless of the moving direction of the relative linear movement. Since either the means or the second transmission means can be pressed so as to rotate and move in the power generation rotation direction, power generation can be reliably performed.

According to the power generation system described in Appendix 3, when the pressing means rotates and moves in one direction of the rotation direction in the in-plane rotation of the virtual surface, the first tooth portion and the second tooth portion provide the first transmission means and the first transmission means. 2 When the transmission means is pressed and rotationally moves in the power generation rotation direction, and the pressing means rotates and moves toward the other side of the rotation direction in the in-plane rotation of the virtual surface, the third tooth portion passes through the fourth transmission means. Since the first tooth portion, the second tooth portion, and the third tooth portion are formed so that the third transmission means is pressed and rotationally moves in the power generation rotation direction, the rotation direction in the in-plane rotation of the virtual surface. When the pressing means rotates and moves regardless of this, the pressing means can press the first transmitting means, the second transmitting means, or the third transmitting means so as to rotate and move in the power generation rotation direction. As a result, as compared with the case where the third transmission means, the fourth transmission means, and the third tooth means are not provided, power can be generated regardless of the rotation direction in the in-plane rotation of the virtual surface of the pressing means. The amount can be increased.

According to the power generation system described in Appendix 4, when the relative linear movement is in the vertical and diagonal directions and a horizontal component force is applied to the receiving portion, the pressing means is moved in the upward diagonal direction. When the transmission means is pressed by the main body and rotates in a straight line, and the horizontal component force is no longer applied to the receiving part after the pressing means moves linearly in the upward diagonal direction. The transmission means and the pressing means are installed so that the transmitting means is pressed and rotationally moved by the main body when the pressing means moves linearly in a downward oblique direction as the weight of the pressing means drops. Therefore, when the pressing means moves relatively linearly in the vertical and diagonal directions, power can be generated by using the wave force and the weight of the pressing means, as compared with the case where only the wave force is used to generate power. , It is possible to reliably generate power in the power generation system regardless of the movement direction of the relative linear movement.

According to the power generation system described in Appendix 5, when the pressing means moves linearly in the upward diagonal direction, the water of the wave flows into the receiving portion and the pressing means moves linearly in the downward diagonal direction. Since the receiving portion is formed so that the water flowing into the receiving portion flows out to the outside of the receiving portion, the pressing means can be relatively linearly moved downward by the weight of the water flowing into the receiving portion. Therefore, the relative linear movement of the pressing means can be reliably performed as compared with the case where the receiving portion is formed so that the water of the wave does not flow into the receiving portion.

According to the power generation system described in Appendix 6, the internal shape of the accommodating means is amplified by the waves flowing into the accommodating means to amplify the internal water level of the accommodating means, thereby promoting the relative linear movement of the pressing means. Since the shape is formed so that the accommodating means can be made to have a uniform shape, the internal water level of the accommodating means can be amplified when a wave flows into the accommodating means as compared with the case where the internal shape of the accommodating means is made uniform. When the inflowing wave flows out of the accommodating means, the internal water level of the accommodating means can be rapidly lowered. Therefore, the relative linear movement of the pressing means can be effectively performed, and the amount of power generated by the power generation system can be increased.

According to the power generation system described in Appendix 7, when the vertical component force of the wave force is applied to one of the pair of vertical bar portions in the case where the movement direction of the relative linear movement is the vertical direction, The first transmission means housed in one of the pair of vertical bar portions while deforming the first floating body portion so that the levels of the second floating body portions housed in each of the pair of vertical bar portions are substantially the same. And the second transmission means linearly moves upward in one of the relative linear movement directions, so that either the first tooth portion or the second tooth portion of the pressing means is used. Either one of the first transmission means or the second transmission means is pressed and rotates, and the first transmission means and the second transmission means housed in one of the pair of vertical bar portions move linearly upward. If the vertical component force is no longer applied to one of the pair of vertical bar portions, the level of the second floating body portion accommodated in each of the pair of vertical bar portions is substantially the same. 1 While deforming the floating body portion, the first transmission means and the second transmission means move in the other direction of the relative linear movement as the weight of the first transmission means and the second transmission means drops. By moving linearly downward, either the first tooth portion or the second tooth portion of the pressing means presses either the first transmitting means or the second transmitting means and rotates. Since the first transmission means, the second transmission means, and the pressing means are installed so as to move, it is possible to obtain the vertical component force required for power generation even when the power generation system is installed offshore, for example. Therefore, it is possible to generate a desired amount of power by using the vertical component force.

According to the power generation system described in Appendix 8, the opening diameter of the first paraboloid is made larger than the opening diameter of the second paraboloid, and the first paraboloid and the second paraboloid face each other. As such, the first reflecting means and the second reflecting means are arranged, and the wave force of the wave collected between the first paraboloid and the second paraboloid is used, and the first by the pressing means. Since either the transmission means or the second transmission means is pressed to enable rotational movement, the pressing means is amplified by amplifying the water level between the two, as compared with the case where a wave other than the waves collected between the two is used. It is possible to effectively press the first transmission means or the second transmission means by the method, and it is possible to increase the amount of power generated by the power generation system.

According to the power generation system described in Appendix 9, either one of the first transmission means or the second transmission means rotates at a lower speed or a higher speed than the other of the first transmission means or the second transmission means. Since the first transmission means or the second transmission means is formed, when the movement efficiency of the pressing means differs depending on the movement direction of the relative linear movement in the pressing means, the first transmission means or the second transmission means By changing the rotation speed, the moving efficiency of the pressing means can be improved, and the power generation efficiency of the power generation system can be maintained.

The external force is converted into a rotational force in the power generation rotation direction, and the converted rotational force is transmitted to the power generation means.
The rotational force conversion means
A transmission means for transmitting the rotational force to the power generation means by rotating itself, and
A pressing means for pressing the transmitting means is provided so that the transmitting means can rotate and move.
The transmission means
A first transmission means that can rotate only in the same direction as the power generation rotation direction,
A second transmission means provided at a distance from the first transmission means and capable of rotating only in the same direction as the power generation rotation direction.
The external force is applied to the pressing means, the first transmitting means, or the second transmitting means in the plane of the virtual surface orthogonal to the rotation center axis of each of the first transmitting means and the second transmitting means. In some cases, the first transmitting means, the second transmitting means, and the pressing means move relatively linearly along the virtual surface, so that the pressing means causes the first transmitting means or the second transmitting means. The pressing means is formed so that one of the two is pressed and rotates.
In the power generation means, when the relative linear movement is a movement in one movement direction of the linear movement, the rotation shaft is rotated by the rotational force transmitted by the first transmission means. As a result, power is generated, and when the relative linear movement is a movement in the other movement direction of the linear movement, the rotation axis is rotated by the rotational force transmitted by the second transmission means. Generate power by doing
The first transmission means or the first transmission means or the said so that either one of the first transmission means or the second transmission means rotates at a lower speed or a higher speed than the other of the first transmission means or the second transmission means. Formed a second means of communication,
Power generation system.
