A piezoelectric element basically has a structure in which a piezoelectric body is sandwiched between two electrodes, and a voltage is generated when pressure is applied to the piezoelectric body. Conventionally, various power generation devices using this piezoelectric element are known. For example, in Patent Document 1, one end of a piezoelectric element is fixed to a fixed portion and the other end is a free end. A power generation device having a weight attached thereto is disclosed. In this power generation device, the piezoelectric element is bent so that the free end moves up and down around one end, and power is generated by this deformation.

However, in the power generation apparatus as described above, there is a demand for a power generation apparatus that can generate power more efficiently because the voltage obtained from the piezoelectric element is sufficient, but sufficient current cannot be obtained, so that the power that can be extracted is small. . Then, this invention makes it a subject to provide the electric power generating apparatus which can generate electric power efficiently, and an electric power generation system using the same.

The first, second, and third power generation devices according to the present invention include a support body connected to a holding means via an elastic member and held in a hollow state, and one end supported by the support body on the other side. A diaphragm having a free end is provided, and power generation means for generating electricity by vibrating the diaphragm. In the first power generation device, the power generation means is a piezoelectric element attached to at least one surface of the diaphragm.

According to the first power generation device, when vibration is applied to the support, the vibration is transmitted to the diaphragm, and the diaphragm is elastically vibrated with the other end bent up and down around one end, and pressure is applied to the piezoelectric element. Join and generate electricity. Since the support is held in a hollow state by the holding means via the elastic member, the applied vibration is amplified, the amplitude is increased, and the vibration is continued for a longer time, so that the support is more efficient. Power generation is possible. The holding means is not particularly limited as long as the support can be held in a hollow state via an elastic member, and is a concept including, for example, a frame-shaped member or a building. Further, the support need not be held by the holding means only by the elastic member, and it is sufficient that at least one elastic member is interposed between the support and the holding means. Furthermore, the elastic member may be connected to other members such as a string, and it is sufficient that the elastic member is interposed between at least the support and the holding means.

In the first power generation device, the support body includes a frame body and a column body, and the frame body is connected to the holding means via the elastic member and is held in a hollow state. The body and the diaphragm are disposed inside the frame body, one end of the diaphragm is supported by the column body, a third magnet is attached to the other end of the diaphragm, and the frame A fourth magnet is attached to the body at a position facing the third magnet. According to this configuration, when vibration is applied to the frame, the diaphragm is forcibly vibrated by the action of the third and fourth magnets. For this reason, it is possible to greatly improve the power generation amount.

A fifth coil attached to the other and a first coil attached to the other, and the diaphragm vibrates with respect to the opposing plate, whereby the fifth magnet faces the first coil. Pass through the position to be. According to this configuration, the positional relationship between the fifth magnet and the first coil changes due to the fifth magnet passing through the position facing the first coil due to the vibration of the diaphragm. As a result, the lines of magnetic force passing through the first coil change, so that power is generated by the first coil.

According to this configuration, when vibration is applied to the frame, the diaphragm is forcibly vibrated by the action of the third and fourth magnets. For this reason, as compared with the case where the third and fourth magnets are not provided, the diaphragm generates vibration with a larger displacement. For this reason, the lines of magnetic force passing through the first coil change greatly, so that the amount of power generation can be significantly improved.

A third power generation device according to the present invention includes: a counter plate that is supported at one end by the support and faces the diaphragm; and an interlocking member disposed between the diaphragm and the counter plate. The power generation means further includes a sixth magnet attached to one of the interlocking member and the counter plate, and a second coil attached to the other, and the interlocking is accompanied by vibration of the diaphragm. As the member vibrates with respect to the counter plate, the sixth magnet passes through a position facing the second coil. According to this configuration, as the interlocking member vibrates with the vibration of the diaphragm, the sixth magnet passes through the position facing the second coil, and the position of the sixth magnet and the second coil. The relationship changes. As a result, the lines of magnetic force passing through the second coil change, so that power is generated by the second coil.

In the third power generation device, the support includes a frame and a column, and the frame is connected to the holding unit via the elastic member and held in a hollow state, and the column A body, the diaphragm, the interlocking member, and the counter plate are disposed inside the frame, and one end of the diaphragm and the counter plate is supported by the column body, and the other end of the diaphragm A third magnet is attached to the frame body, and a fourth magnet is attached to the frame body at a position facing the third magnet. According to this configuration, when vibration is applied to the frame, the diaphragm is forcibly vibrated by the action of the third and fourth magnets. For this reason, as compared with the case where the third and fourth magnets are not attached, the vibration plate and the interlocking member generate vibration with a larger displacement. Therefore, it is possible to greatly improve the power generation amount.

In the first, second, and third power generators, the support is connected to the holding means via at least two elastic members, and each elastic member is disposed at a position facing each other via the support. It can also be configured as described. According to this configuration, since the elastic members are alternately expanded and contracted, vibrations by the elastic members can be continuously applied to the support for a longer time.

It should be noted that the elastic member is preferably a member such as a tension spring or rubber that causes a tensile force to act on the support when the support is stationary.

Also, it is preferable that a weight is attached to the other end of the diaphragm in order to vibrate more efficiently.

And a moving body that moves so as to cross the power generation unit.

According to the second power generation system, when the moving body crosses the power generation unit, each second magnet approaches each corresponding first magnet, and the support body to which each first magnet is attached can be shaken. As a result, as described above, the piezoelectric element efficiently generates power.

In the second power generation system, each first magnet and each second magnet are arranged so that each second magnet sequentially crosses each corresponding first magnet when the moving body crosses the power generation unit. It is preferable that they are arranged. According to this structure, since each 1st magnet and each 2nd magnet do not exert magnetic force simultaneously, the driving force required to move a moving body can be made small.

A third power generation system according to the present invention includes the second and third power generation apparatuses, and a moment applying unit that applies a moment for rotating the frame to the frame. According to the third power generation system, the moment is applied from the moment applying means to the frame so that the frame rotates. Therefore, the diaphragm can be vibrated, and power generation is performed by the power generation means.

A link mechanism; and a drive mechanism for applying a moment about the second shaft member to the link mechanism, wherein the frame and the link mechanism are a third shaft member parallel to the first and second shaft members The link mechanism transmits the applied moment to the frame body via the third shaft member, thereby giving the frame body a moment around the first shaft member. According to this configuration, a moment for rotating the frame body is transmitted from the drive mechanism to the frame body via the link mechanism. Thereby, the frame can be rotated to vibrate the diaphragm, and power generation is performed by the power generation means.

In the third power generation system, the link mechanism is connected to the frame body at one end via the third shaft member, and a force is applied from the drive mechanism to the other end to rotate around the second shaft member. A moment is applied, and the length from the second shaft member to one end of the link mechanism is shorter than the length from the second shaft member to the other end of the link mechanism. According to this configuration, the driving force required to rotate the support body can be greatly reduced due to the lever principle.

In the third power generation system, a plurality of the power generation devices are arranged side by side in a predetermined direction, and the frame body of each of the power generation devices is rotatable about the first shaft member, and a plurality of the power generation devices The frame body of the power generation device at one end (hereinafter referred to as a frame body at one end) is connected to the link mechanism via the third shaft member, and the two power generation devices adjacent to each other. The frame body is connected via a fourth shaft member parallel to the first, second, and third shaft members, and the link mechanism transmits the applied moment to the one end via the third shaft member. By transmitting to the frame body, a moment around the first shaft member is applied to the frame body at the one end, and the frame body of the power generation apparatus on one side of the two adjacent power generation apparatuses is The applied moment is transferred to the other side via the fourth shaft member. Serial By transferred to the frame of the power generator, to impart the first shaft member about the moment the frame of the power generator said other side. According to this configuration, in the plurality of power generation devices arranged in the predetermined direction, from the power generation device on one side to the power generation device on the other side via the fourth shaft member in response to the drive mechanism being driven. Then, the moment for rotating the frame is sequentially transmitted. Therefore, each of the plurality of power generation devices can vibrate the diaphragm and generate power. For this reason, since many power generators can generate electric power by one drive of a drive mechanism, it is possible to improve a power generation amount significantly.

Moreover, it is preferable that the moving body or the drive mechanism in the first, second, and third power generation systems is a rotation shaft that is rotatably installed. In this case, the rotating shaft has a plurality of blades at one end, and the power generation system is connected to the casing that covers one end of the rotating shaft and includes an intake portion and an exhaust portion, and the exhaust portion. And an exhaust tower extending upward.

In such a configuration, since the exhaust tower is connected to the exhaust part of the casing, an air flow flowing from the intake part to the exhaust part and the exhaust tower is generated. By the generation of this air flow, air collides with a plurality of blades at one end of the rotation shaft, and the rotation shaft can be rotated.

In addition, a plurality of power generation units having a power generation device and the rotating shaft, wind pressure detection means for detecting the wind pressure of air sucked into the casing, and operation of each power generation unit by the wind pressure detected by the wind pressure detection means. And a control means for controlling. Instead of the wind pressure detection means, a rotation speed detection means for detecting the rotation speed of the rotating shaft is provided, and the control means operates each power generation unit according to the rotation speed detected by the rotation speed detection means instead of the wind pressure. It can also be configured to control. According to this configuration, the number of power generating units that can be sufficiently operated is determined from the wind pressure detected by the wind pressure detecting means (or the rotational speed detected by the rotational speed detecting means), and the control means Only the power generating unit that can be operated rotates the rotating shaft, and the other power generating units stop operating by stopping the rotation of the rotating shaft.

In addition, the exhaust unit is further provided with a damper, and a rotation number detection unit that detects the rotation number of the rotation shaft, and a control unit that controls the opening degree of the damper based on the rotation number detected by the rotation number detection unit. It can also be configured. In place of the rotation speed detection means for detecting the rotation speed of the rotation shaft, a wind pressure detection means for detecting the wind pressure of the air sucked into the casing is provided, and the control means is detected by the wind pressure detection means instead of the rotation speed. It is good also as a structure which controls the opening degree of a damper with the made wind pressure. According to this configuration, the control means adjusts the amount of intake air from the intake portion by adjusting the opening of the damper based on the rotational speed of the rotating shaft (or the wind pressure of air sucked into the casing). The rotational speed of the rotary shaft can be controlled to an appropriate rotational speed.

Moreover, it can also be set as the structure further equipped with the condensing lens which condenses sunlight, and the heat receiving plate provided in the exhaust part heated by the sunlight condensed by the condensing lens. According to this configuration, the temperature in the exhaust part can be increased, and as a result, the air permeability of the air flowing in the order of the intake part, the exhaust part, and the exhaust tower can be increased.

Hereinafter, embodiments of a power generation apparatus according to the present invention and a power generation system using the power generation apparatus will be described with reference to the drawings.

As shown in FIG. 1, the power generator 1 includes a holding frame (holding means) 2, a support frame (support) 3 held in a hollow state in the holding frame 2, and two supported by the support frame 3. The main components are a diaphragm 4, a plurality of piezoelectric elements 5 attached on each diaphragm 4, and a tension spring 6 interposed between the holding frame 2 and the support frame 3.

The holding frame 2 is a rectangular frame in plan view, and includes a pair of long side walls 21 and a pair of short side walls 22. At both ends of the inner wall surface of each long side wall 21, a fixture 23 for attaching one end of the tension spring 6 is provided. The holding frame 2 can be made of various materials and is not particularly limited. For example, the holding frame 2 can be formed of plastic or light metal. In the present embodiment, the portable holding frame 2 is illustrated as a holding means for holding the support frame 3, but the holding means is not particularly limited to this, for example, a wall of a building Such a thing that is not portable can be used as the holding means.

The support frame 3 held by the holding frame 2 is an annular frame formed slightly smaller than the holding frame 2. Specifically, the support frame 3 is a rectangular frame in plan view, and includes a pair of long side walls 31 and a pair of short side walls 32. At both end portions of the inner wall surface of each long side wall 31 (positions facing the mounting portion 23 of the holding frame 2), mounting tools 33 for mounting the other end of the tension spring 6 are provided. By attaching the tension spring 6 to the fixture 33 of the support frame 3 and the fixture 23 of the holding frame 2, the support frame 3 is held in a hollow state with respect to the holding frame 2 inside the holding frame 2. Yes. That is, as shown in FIG. 2, since the height of the support frame 3 is formed lower than the height of the holding frame 2, when the holding frame 2 is placed on or attached to a horizontal plane, the support frame 3 is It is held in a state of floating from the horizontal plane.

The support frame 3 has two diaphragms 4 attached thereto. Each diaphragm 4 is a rectangular plate in plan view, and as shown in detail in FIG. 2, one end is fixed to each short side wall 32 of the support frame 3, and the other end is a free end. It has become. Further, since the diaphragm 4 is formed of a material that elastically vibrates, when vibration or the like is applied to the support frame 3, the diaphragm 4 moves so that the free end moves up and down, and the entire diaphragm 4 vibrates elastically. It has become. In addition, since the weight 7 is attached to the free end of the diaphragm 4, it is easier to elastically vibrate. The material of the diaphragm 4 is not particularly limited as long as it can elastically vibrate, and examples thereof include plastic, FRP (Fiber Reinforced Plastics), carbon fiber, stainless steel, spring steel, and the like. be able to.

A plurality of piezoelectric elements 5 are attached to the upper surface of each diaphragm 4. As the piezoelectric element 5, a known piezoelectric element can be used, and when the diaphragm 4 is bent by vibration, the piezoelectric element 5 generates pressure by applying pressure. Various methods can be used for attaching the piezoelectric element 5 to the diaphragm 4. For example, the piezoelectric element 5 can be attached by baking, an adhesive, a pressure-sensitive adhesive, a rivet, a screw, or the like. Although the number and arrangement of the piezoelectric elements 5 are not particularly limited, in this embodiment, a total of eight piezoelectric elements 5 of 2 × 4 are installed on one diaphragm 4.

The power generation apparatus 1 configured as described above is elastic so that the vibration is transmitted to the diaphragm 4 when the support frame 3 is subjected to vibration and the like so that the diaphragm 4 is bent up and down around the fixed end. As a result, a pressure is applied to the piezoelectric element 5 mounted on the diaphragm 4 to generate electricity. Since the support frame 3 is held in the holding frame 2 in a hollow state by the tension spring 6, vibration applied to the support frame 3 is amplified by the tension spring 6 to have a larger amplitude and for a longer time. Since it is possible to vibrate, the piezoelectric element 5 can generate power more efficiently.

The power generation apparatus 1 configured as described above can be installed in various places. For example, by installing it under a bridge or on a road, the power generation apparatus 1 generates power using vibration generated when a car or the like passes. can do.

Next, a power generation system 10 using a part of the power generation apparatus 1 described above will be described.

As shown in FIG. 3, the power generation system 10 is configured such that the rotary shaft 8 is rotatably installed, and a plurality of power generation units 20 are arranged radially around the rotary shaft 8.

First, the power generation unit 20 used in the system 10 is composed of a plurality of power generation devices 1 '. This power generation device 1 ′ has the same basic configuration as that of the above-described power generation device 1, but there are portions that are partially different from the power generation device 1. Hereinafter, description of the same part as the power generation device 1 is omitted, and only different parts will be described.

First, the holding frame 2 ′ of each power generation device 1 ′ is shared by each power generation unit 20. The holding frame 2 ′ is composed of a main column 22 ′ extending along the rotation axis 8, and a plurality of long side walls 21 extending laterally from the main column 22 ′ toward the rotation axis 8. Between the long side walls 21, the support frame 3 is held in a hollow state. Note that the power generation unit 20 may be configured by simply combining the above-described power generation devices 1 in the vertical direction and removing the short side wall 22 on the rotating shaft 8 side.

The first magnet M1 is attached to the short side wall 32 located on the rotating shaft 8 side of each support frame 3. Three diaphragms 4 extend from the inner wall surface of each short side wall 32, and a total of six diaphragms 4 are attached to one support frame 3. A plurality of power generation units 20 configured in this way are arranged radially about the rotation shaft 8. In FIG. 3, only one power generation unit 20 is shown in detail, and the remaining power generation units 20 are omitted or only the holding frame 2 'is shown.

The rotary shaft 8 has four second magnets M2 attached to the outer peripheral surface thereof, and is disposed at a position facing the first magnets M1 attached to the support frames 3 arranged in the vertical direction. These are arranged in the axial direction of the rotary shaft 8 at the same intervals as the first magnet M1. The first magnet M1 and the second magnet M2 are attached so that the opposite poles face each other so as to repel each other. Further, each of the four second magnets M2 is arranged so as to be displaced in the circumferential direction of the rotating shaft 8, and only one is arranged on the same straight line extending in the axial direction of the rotating shaft 8. . For this reason, when the rotating shaft 8 is rotated, each of the second magnets M2 sequentially repels the corresponding first magnet M1 and does not repel at the same time. The required driving force can be reduced. The four second magnets M2 vibrate each support frame 3 of the power generation unit 20 that is adjacent to the power generation unit 20 in a clockwise direction after all the support frames 3 of the one power generation unit 20 are vibrated. It is arranged like this.

The power generation method by the power generation system 10 configured as described above will be described. First, when the rotating shaft 8 is rotated manually or clockwise by some drive source, The second magnet M2 positioned at the position approaches the corresponding uppermost first magnet M1, and the uppermost support frame 3 is vibrated by a repulsive force. Due to this vibration, in the uppermost power generator 1 ′, the diaphragm 4 is bent, and pressure is applied to the piezoelectric element 5 on the diaphragm 4 to generate power. Further, since the support frame 3 is held on the holding frame 2 ′ by the tension spring 6, the vibration is amplified and has a larger amplitude and vibrates for a longer time. When the rotating shaft 8 further rotates, the second magnet M2 that is the second from the top approaches the first magnet M1 that is attached to the second support frame 3 from the top, and the second power generation from the top. In the apparatus 1 ′, power generation is performed in the same manner. Then, when the rotating shaft 8 further rotates, similarly, the third support frame 3 from the top vibrates, and then the bottom support frame 3 vibrates, so that power generation is performed in order from top to bottom. Is called. Next, power generation is sequentially performed from the top in the same manner also in the power generation unit 20 adjacent to the clockwise side.

When the second magnet M2 corresponding to the first magnet M1 of the support frame 3 approaches while the support frame 3 is swinging due to the expansion and contraction of the tension spring 6, the swing of the support frame 3 is reversed by the magnetic force. Therefore, after the support frame 3 is shaken once, it is preferable to set the rotation speed so that the second magnet M2 approaches the first magnet M1 when the support frame 3 has stopped shaking. For example, the rotational speed of the rotary shaft 8 can be about 1 to 500 rpm, and preferably about 30 to 200 rpm. Moreover, in the said embodiment, although the 1st and 2nd magnets M1 and M2 faced the same poles so that it might mutually repel, you may face different poles so that it may mutually attract. Moreover, an electromagnet may be used instead of the permanent magnet as described above.

Further, the power generation unit 20 used in the power generation system 10 may include a plurality of power generation devices 200 shown in FIG. 4 instead of the power generation device 1 ′ (FIG. 3).

In the power generation device 200, the support frame 3 includes an annular frame 3a and a column 3b. The frame 3a is a rectangular frame. The column 3b is arranged at the center inside the frame 3a.

The holding frame 2 'is provided with a first shaft member 45 penetrating the frame body 3a and the column body 3b. The frame 3a is rotatable around the first shaft member 45. The column 3b is joined to the first shaft member 45 and does not rotate. In addition, the 1st shaft member 45 and the column 3b may be comprised from the same member instead of a separate member.

A cylindrical bearing 60 is attached to the first shaft member 45. The bearing 60 is disposed between the upper end of the frame 3a and the holding frame 2 ', or between the lower end of the frame 3a and the holding frame 2'. The bearing 60 holds the frame 3a in a hollow state.

Each corner of the frame 3a is connected to the holding frame 2 'via a tension spring 6.

1st magnet M1 is attached to the short side wall 90 by the side of the rotating shaft 8 in the frame 3a. The first magnet M1 faces the second magnet M2 of the rotating shaft 8.

The diaphragm 4 is disposed inside the frame 3a. One end of the diaphragm 4 is supported by the column 3b.

A third magnet M3 is attached to the other end of the diaphragm 4. A fourth magnet M4 is attached to the frame 3a at a position facing the third magnet M3. The third magnet M3 and the fourth magnet M4 are attached so that the opposite poles face each other so as to repel each other.

In the example of FIG. 4, three diaphragms 4 are attached to the left and right side surfaces of the column 3b. A total of six piezoelectric elements 5 of 2 × 3 are installed on the upper surface of each diaphragm 4. The number of diaphragms 4 and piezoelectric elements 5 is not limited to the above and can be arbitrarily set. Moreover, the diaphragm 4 may be attached only to one side surface of the column 3b.

In the power generation system 10 configured as described above, when the rotating shaft 8 is rotated to bring the second magnet M2 closer to the first magnet M1, the repulsive force of the first and second magnets M1 and M2 The frame 3a rotates around the first shaft member 45. As a result, as shown in FIG. 5, the fourth magnet M4 approaches the third magnet M3, and the repulsive forces of the third and fourth magnets M3 and M4 act on the diaphragm 4. As a result, the vibration plate 4 vibrates and bends, whereby pressure is applied to the piezoelectric element 5 on the vibration plate 4 and power generation is performed.

According to the above modification, the diaphragm 4 is forcibly vibrated by the action of the third and fourth magnets M3 and M4. For this reason, it is possible to greatly improve the power generation amount.

Further, after the frame 3a is turned by the action of the first and second magnets M1 and M2, the frame 3a is turned to one side and to the other side by the action of the tension spring 6. The rotation is repeated. For this reason, the 4th magnet M4 and the 3rd magnet M3 approach many times, and power generation continues for a long time.

Further, the power generation unit 20 may include a plurality of power generation apparatuses 201 shown in FIG. The power generation apparatus 201 includes a later-described fifth magnet M5 (FIG. 7) and coils 65, 66, and 67 as power generation means.

In the power generation apparatus 201, the support frame 3 includes an annular frame 3a and a column 3b, as in the power generation apparatus 200 of FIG. The frame 3 a is held in a hollow state by the bearing 60. Each corner of the frame 3a is connected to the holding frame 2 'via a tension spring 6. The frame body 3 a is rotatable about the first shaft member 45, and the column body 3 b is joined to the first shaft member 45. In addition, the 1st shaft member 45 and the column 3b may be comprised from the same member instead of a separate member. A second magnet M2 is attached to the frame 3a.

Inside the frame 3a, a diaphragm 46 and a counter plate 50 are arranged to face each other in the vertical direction. In the example of FIG. 6, the diaphragms 46 and the counter plates 50 are alternately attached to the side surfaces on both the left and right sides of the column 3b. The number of diaphragms 46 and counter plates 50 is not limited to the above and can be arbitrarily set. Further, the diaphragm 46 and the counter plate 50 may be attached only to one side surface of the column body 3b.

Each diaphragm 46 includes a magnet case 47, a case support 48, and a leaf spring 49. One end of the plate spring 49 is supported by the column 3b. The case support 48 is attached to the other end of the leaf spring 49. The magnet case 47 is attached to the lower surface of the case support 48.

A third magnet M3 is attached to the other end of the diaphragm 46 (case support 48). A fourth magnet M4 is attached to the frame 3a at a position facing the third magnet M3.

The counter plate 50 is a plate material having higher rigidity than the plate spring 49, for example. One end of each counter plate 50 is supported by the column 3b.

As shown in FIG. 7, in each diaphragm 46, a fifth magnet M <b> 5 is attached to the lower surface of the magnet case 47 via a back yoke 51. The fifth magnet M <b> 5 includes an S pole 52, an N pole 53, and an S pole 54 arranged in the vibration direction of the diaphragm 46.

65, 66, and 67 are arranged in the vibration direction of the diaphragm 46 below the fifth magnet M5. FIG. 7A shows the initial position before vibration. In this initial position, the central coil 66 faces the N pole 53, and the

outer coils

65 and 67 face the

S poles

52 and 54.

In the power generation system 10 configured as described above, when the rotary shaft 8 is rotated, the frame body 3a of the support frame 3 causes the first shaft member 45 to move by the repulsive force of the first and second magnets M1 and M2. Rotate to the center. As a result, as shown in FIG. 8, the fourth magnet M4 approaches the third magnet M3, and the repulsive forces of the third and fourth magnets M3 and M4 act on the diaphragm 46. As a result, as shown in FIG. 9, the diaphragm 46 vibrates with respect to the counter plate 50. As a result, the fifth magnet M5 attached to the magnet case 47 reciprocates above the

coils

65, 66, and 67 and passes through a position facing the

coils

65, 66, and 67. By this reciprocation, the positional relationship between the fifth magnet M5 (the S pole 52, the N pole 53, and the S pole 54) and the

coils

65, 66, and 67 changes, and the magnetic lines of force that pass through the

coils

65, 66, and 67 change. Change. Specifically, as shown in FIG. 7A, when the S pole 52, the N pole 53, and the S pole 54 face the

coils

65, 66, and 67, the S pole 52 and the N pole 53 are The magnetic field lines passing through the

coils

65 and 66 are formed, and the N pole 53 and the S pole 54 form magnetic field lines passing through the

coils

66 and 67. Then, as shown in FIG. 7B, in the state where the diaphragm 46 is displaced to one side with respect to the counter plate 50 and the N pole 53 and the S pole 54 face the

coils

65 and 66, the N pole 53 and the S pole 54 form magnetic lines of force that pass through the

coils

65 and 66, and the S pole 52 does not form magnetic lines of force that pass through the coils. 7C, when the diaphragm 46 is displaced to the other side with respect to the opposing plate 50, and the S pole 52 and the N pole 53 are opposed to the

coils

66 and 67, the S pole. 52 and N pole 53 form a magnetic field line passing through the

coils

66 and 67, and the S pole 54 does not form a magnetic field line passing through the coil. As described above, according to the present modification, the lines of magnetic force passing through the

coils

65, 66, and 67 change according to the positional relationship between the fifth magnet M5 and the

coils

65, 66, and 67. Power generation is performed at 65, 66 and 67.

Also in the above modification, the diaphragm 46 is forcibly vibrated by the action of the third and fourth magnets M3 and M4. For this reason, as compared with the case where the third and fourth magnets M3 and M4 are not attached, the diaphragm 46 generates a vibration with a larger displacement. For this reason, it is possible to greatly improve the power generation amount.

In the modified example, the fifth magnet M5 is attached to the diaphragm 46, and the

coils

65, 66, and 67 are attached to the opposing plate 50. On the contrary, the

coils

65, 66, and 67 are attached to the diaphragm 46. 66 and 67 may be attached, and the fifth magnet M5 may be attached to the opposing plate 50. Even in this case, the vibration plate 46 vibrates with respect to the counter plate 50, whereby the positional relationship between the fifth magnet M5 (the S pole 52, the N pole 53, and the S pole 54) and the

coils

65, 66, and 67 is obtained. Therefore, power is generated by the

coils

65, 66, and 67.

In addition, the power generation device of the above modification is an axial type in which the magnetic lines of force are parallel to the axial direction of the support body (column body 3b) of the diaphragm 46. A radial type power generator that is perpendicular to the axial direction of the support (column 3b) may be used.

When the power generation device is a radial type, for example, a diaphragm 500 and a counter plate 600 shown in FIG. 10 are provided instead of the diaphragm 46 and the counter plate 50 shown in FIG. The diaphragm 500 and the counter plate 600 are disposed inside the frame 3a (FIG. 6) and face each other in the vertical direction.

65, 66, and 67 (first coil) are attached to one side surface of the coil support member 610. As the

coils

65, 66, and 67, those having a core can be used.

The

coils

65, 66, and 67 are arranged in the vibration direction (arrow A) of the diaphragm 500. The

coils

65, 66, 67 and the fifth magnet M5 (S pole 52, N pole 53, S pole 54) face each other in a direction perpendicular to the axial direction (vertical direction) of the column 3b.

In the above modification, the magnetic lines of force generated by the fifth magnet M5 in the

coils

65, 66, and 67 are directed in a direction perpendicular to the axial direction (vertical direction) of the column 3b.

And if the rotating shaft 8 (FIG. 6) is rotated and the repulsive force of the 3rd and 4th magnet M3 and M4 is produced, the diaphragm 500 will vibrate with respect to the opposing board 600. FIG. As a result, the fifth magnet M5 reciprocates in front of the

coils

65, 66, and 67 and passes through a position facing the

coils

65, 66, and 67 changes, and the magnetic lines of force that pass through the

coils

65, 66, and 67 change. Change. Therefore, power generation is performed.

Further, when the power generation device is a radial type, for example, the diaphragm 700, the interlocking member 800, or the counter plate 900 shown in FIG. 11 may be provided instead of the diaphragm 46 and the counter plate 50 shown in FIG.

The diaphragm 700, the interlocking member 800, and the counter plate 900 are disposed inside the frame 3a (FIG. 6). The diaphragm 700 and the counter plate 900 face each other in the vertical direction. The interlocking member 800 is disposed between the diaphragm 700 and the counter plate 900.

The diaphragm 700 includes a leaf spring 710, a shaft support portion 720, and a drive shaft 730.

One end of the plate spring 710 is supported by the column 3b.

The shaft support portion 720 includes a base portion 721 and an arm portion 722.

The other end of the leaf spring 710 is connected to one side surface of the base 721.

The arm portion 722 extends from the upper end of the base portion 721 to the other side. A third magnet M3 is attached to the other end of the arm portion 722. The third magnet M3 faces the fourth magnet M4 attached to the frame 3a (FIG. 6).

The drive shaft 730 is supported by the arm portion 722 and extends downward from the lower surface of the arm portion 722.

The interlocking member 800 includes a stay 810, a magnet case 820, and a protrusion 830.

The stay 810 extends from one side to the other side along the upper surface of the counter plate 900. On one side of the stay 810, a connecting portion 811 that is rotatably connected to the counter plate 900 is provided.

The magnet case 820 is attached to the other end of the stay 810. The magnet case 820 extends vertically between the arm portion 722 and the counter plate 900. The lower end of the magnet case 820 is slidably supported by the counter plate 900.

The protrusion 830 extends from the upper end of the magnet case 820 to one side. A through hole 831 is formed in the protrusion 830. By passing the drive shaft 730 through the through-hole 831, the interlocking member 800 can vibrate with the vibration of the diaphragm 700.

The sixth magnet M6 is attached to the other side surface of the magnet case 820. The sixth magnet M6 includes an S pole 74, an N pole 75, and an S pole 76. The S pole 74, the N pole 75, and the S pole 76 are arranged in the vibration direction (arrow A) of the interlocking member 800.

One end of the counter plate 900 is supported by the column 3b. A coil support member 910 is attached to the other end of the counter plate 900.

The coil support member 910 is located on the other side of the magnet case 820 and extends vertically.

Coils

93, 94, and 95 (second coil) are attached to one side surface of the coil support member 910. As the

coils

93, 94, and 95, those having a core can be used.

The

coils

93, 94, 95 are arranged in the vibration direction (arrow A) of the interlocking member 800. The

coils

93, 94, 95 and the sixth magnet M6 (S pole 74, N pole 75, S pole 76) face each other in a direction perpendicular to the axial direction (vertical direction) of the column 3b.

In the above modification, the magnetic lines of force generated by the sixth magnet M6 in the

coils

93, 94, 95 are directed in a direction perpendicular to the axial direction (vertical direction) of the column.

And if the rotating shaft 8 (FIG. 6) is rotated and the repulsive force of the 3rd and 4th magnets M3 and M4 is produced, the diaphragm 700 will vibrate. Accordingly, the drive shaft 730 presses the inner surface of the through hole 831 in the vibration direction (arrow B) of the diaphragm 700. By this pressing, the interlocking member 800 vibrates with respect to the opposing plate 50 with the connecting portion 811 as a fulcrum (arrow A). As a result, the sixth magnet M6 (S pole 74, N pole 75, and S pole 76) reciprocates in front of the

coils

93, 94, 95, and passes through the position facing the

coils

93, 94, 95. To do. By this reciprocation, the positional relationship between the sixth magnet M6 and the

coils

93, 94, 95 changes, and the lines of magnetic force passing through the

coils

93, 94, 95 change. Therefore, power generation is performed.

Further, the diaphragm 700 is forcibly vibrated by the action of the third and fourth magnets M3 and M4. For this reason, as compared with the case where the third and fourth magnets M3 and M4 are not attached, the vibration plate 700 and the interlocking member 800 generate vibration with a larger displacement. Therefore, it is possible to greatly improve the power generation amount.

In the above modification, the sixth magnet M6 is attached to the interlocking member 800, and the

coils

93, 94, 95 are attached to the counter plate 900. Conversely, the

coils

93, 94, 95 are attached to the interlocking member 800. And the sixth magnet M6 may be attached to the counter plate 900.

Further, the power generation system of the present invention can be modified as shown in FIG. A power generation system 300 illustrated in FIG. 12 includes a power generation device 202 and a moment application unit 400.

A plurality of power generation devices 202 are arranged in the vertical direction. Each power generation device 202 has the same basic configuration as the power generation device 200 shown in FIG. 4, but is partly different from the power generation device 200. That is, in the power generation device 202, the projection 71 is provided on the frame 3a instead of the first magnet M1 (FIG. 4). A through hole 72 is formed in the protrusion 71.

The moment applying means 400 includes a link mechanism 81 and a rotating shaft 8 (drive mechanism).

The link mechanism 81 is provided for each power generator 202. The link mechanism 81 is connected to the frame body 3a of the power generator 202, and applies a moment around the first shaft member 45 to the frame body 3a.

The link mechanism 81 includes a pair of upper and

lower plate members

82, 82. The

plate members

82 and 82 are supported by the second shaft member 83. The link mechanism 81 (plate members 82, 82) can rotate around the second shaft member 83. The second shaft member 83 is a member integrated with the holding frame 2 ′ and is parallel to the first shaft member 45. A length L1 from the second shaft member 83 to one end of the link mechanism 81 is shorter than a length L2 from the second shaft member 83 to the other end of the link mechanism 81.

One end of each of the

plate members

82 and 82 is connected by a connecting member 84. A cylindrical roller 85 is attached to the connection member 84.

The other ends of the

plate members

82 and 82 are connected by the third shaft member 86. The third shaft member 86 is parallel to the first and

second shaft members

45 and 83. Since the third shaft member 86 is passed through the through hole 72 of the protrusion 71, the link mechanism 81 is connected to the frame body 3 a via the third shaft member 86.

Rotating shaft 8 applies a moment to second link member 83 to link mechanism 81 by applying a force to roller 85.

The rotating shaft 8 has a plurality of protrusions 87 attached to the outer peripheral surface. The protrusion 87 is disposed at a position facing the roller 85 of each link mechanism 81. That is, the protrusions 87 are arranged in the axial direction of the rotary shaft 8 at the same interval as the rollers 85. Further, each of the protrusions 87 is arranged so as to be displaced in the circumferential direction of the rotating shaft 8, and only one protrusion 87 is arranged on the same straight line extending in the axial direction of the rotating shaft 8. Thus, when the rotary shaft 8 rotates, the protrusions 87 sequentially contact the corresponding rollers 85 and do not contact at the same time.

The power generation system 300 is a unit in which a pair of a power generation device 202 and a link mechanism 81 is vertically arranged as one power generation unit. Although not shown, the power generation units described above are installed radially around the rotating shaft 8. Each protrusion 87 of the rotating shaft 8 contacts each roller 85 of one power generation unit, and then contacts each roller 85 of the second power generation unit adjacent to the one power generation unit in the clockwise direction.

In the power generation system 300 described above, when the rotary shaft 8 is rotated, first, in one power generation unit, the projection 87 located at the top comes into contact with the roller 85 attached to the top link mechanism 81. Apply power. As a result, a moment around the second shaft member 83 is applied to the link mechanism 81, and the link mechanism 81 rotates about the second shaft member 83. The link mechanism 81 transmits the moment applied from the rotary shaft 8 to the frame body 3a via the third shaft member 86. Thereby, a moment around the first shaft member 45 is given to the frame 3a. As a result, the frame 3a rotates around the first shaft member 45, whereby the fourth magnet M4 approaches the third magnet M3, and the repulsive force of the third and fourth magnets M3 and M4 is generated. . Therefore, the vibration plate 4 vibrates and bends, and pressure is applied to the piezoelectric element 5 on the vibration plate 4 to generate power.

Then, when the rotating shaft 8 further rotates, the second projection 87 from the top comes into contact with the roller 85 attached to the second link mechanism 81 from the top, and the second power generator 202 from the top similarly Power generation is performed.

Then, when the rotating shaft 8 further rotates, power generation is performed in order from top to bottom, such that power generation is performed by the third power generation device 202 (not shown) from the top.

And next, power generation is performed sequentially from the top in the same manner in the power generation unit adjacent to the clockwise side.

According to the power generation system 300 described above, the moment applying means 400 applies a moment for rotating the frame 3a to the frame 3a. Specifically, a moment for rotating the frame 3 a is transmitted from the rotating shaft 8 to the frame 3 a via the link mechanism 81. Thereby, since the frame 3a rotates, the diaphragm 4 can be vibrated and bent, and power generation is performed.

Further, since the length L1 of the link mechanism 81 is shorter than the length L2, the driving force required for the rotation of the frame 3a can be greatly reduced by the lever principle.

In the power generation system 300, the link mechanism 81 may be omitted, and the frame body 3a may be rotated by bringing the protrusion 87 of the rotating shaft 8 into direct contact with the frame body 3a. Further, instead of the power generation device 202, the power generation device 22 ′ shown in FIG. 3, the power generation device 201 shown in FIG. 6, and the power generation device having the same basic configuration as the modification of the power generation device 201 shown in FIGS. May be provided.

Further, the power generation system 300 can be changed as shown in FIG. In the modification of FIG. 13, a plurality of power generation devices 202 are arranged in the horizontal direction. The frame body 3a of each power generation device 202 is rotatable about the first shaft member 45.

In the frame body 3a of each power generation device 202, a projection 71 is provided on the short side wall 90 on one side (link mechanism 81 side). A through hole 72 is formed in the protrusion 71.

In the frame body 3a of the power generation device 202 at one end (hereinafter referred to as the frame body 3a at one end), the third shaft member 86 of the link mechanism 81 is passed through the through hole 72. Thereby, the frame body 3 a at one end and the link mechanism 81 are connected via the third shaft member 86.

Further, in the frame 3a of each power generator 202, a pair of upper and

lower plate members

89, 89 are provided on the short side wall 91 on the other side (the side opposite to the link mechanism 81).

The other ends of the

plate members

89 and 89 are connected by the fourth shaft member 88. The fourth shaft member 88 is parallel to the first, second, and

third shaft members

45, 83, 86.

In the two adjacent power generation devices 202, the fourth shaft member 88 of the power generation device 202 on one side is passed through the through hole 72 of the power generation device 202 on the other side. Thereby, two adjacent power generators 202 are connected via the fourth shaft member 88.

According to the power generation system 300 described above, when the rotation shaft 8 is rotated and a moment is applied to the link mechanism 81, the link mechanism 81 transmits the applied moment to the one end frame via the third shaft member 86. Transmitted to the body 3a. As a result, a moment around the first shaft member 45 is applied to the frame 3a at one end. As a result, in the power generation device 202 at one end, the frame 3a rotates about the first shaft member 45, and the repulsive force of the third and fourth magnets M3 and M4 is generated. Therefore, the diaphragm 4 vibrates and bends, and pressure is applied to the piezoelectric element 5 to generate power.

Then, the power generation device 202 at one end transmits the moment applied from the rotary shaft 8 to the frame 3 a of the power generation device 202 on the other side via the fourth shaft member 88. Accordingly, in the power generator 202 on the other side, a moment around the first shaft member 45 is applied to the frame body 3a, and the frame body 3a rotates. As a result, also in the power generator 202 on the other side, the diaphragm 4 vibrates by the repulsive force of the third and fourth magnets M3 and M4, and power generation is performed.

Of the two adjacent power generation devices 202, the frame 3a of the power generation device 202 on one side applies the applied moment to the frame 3a of the power generation device 202 on the other side via the fourth shaft member 88. introduce. Accordingly, in the power generator 202 on the other side, a moment around the first shaft member 45 is applied to the frame body 3a, and the frame body 3a rotates. Thereby, the diaphragm 4 vibrates and power generation is performed.

According to the power generation system 300 described above, the frame 3a is moved from the power generation device 202 on one side to the power generation device 202 on the other side via the fourth shaft member 88 according to the rotation of the rotary shaft 8. The rotating moment is transmitted sequentially. As a result, the diaphragm 4 can be vibrated and bent by the respective power generation devices 202 arranged in the horizontal direction, and power generation is performed. Therefore, one rotation of the rotating shaft 8 can cause many power generators to generate power, and the power generation amount can be greatly improved.

In the power generation system 300 described above, the number of power generation devices 202 arranged in the horizontal direction can be arbitrarily set. A plurality of power generators 202 may be arranged in a direction inclined with respect to the horizontal direction.

In the

power generation systems

10 and 300 described above, the rotational drive source of the rotary shaft 8 can be various. For example, as shown in FIG. 14, the rotary shaft 8 is rotated using wind power as the drive source. can do. Reference numeral 100 denotes a power generation unit, which schematically illustrates the above-described rotary shaft 8 and a plurality of power generation units 20 arranged radially around the rotary shaft 8.

More specifically, the lower end portion of the rotating shaft 8 has a plurality of blades (not shown) attached directly or indirectly to constitute a turbine, and the lower end portion of the rotating shaft 8 provided with the blades is the casing 11. Covered by. The casing 11 is connected to an intake duct (intake section) 12 having an intake port 121 and an exhaust duct (exhaust section) 13 that discharges air flowing into the casing 11 from the casing 11. An exhaust tower 14 extending upward is connected to the tip of the exhaust duct 13. According to the

power generation systems

10 and 300, the exhaust tower 14 extending upward is provided, so that air flows in from the intake duct 12 and passes through the casing 11 and the exhaust duct 13, and the upper end of the exhaust tower 14. Discharged from. As described above, since an air flow is generated in the casing 11, air collides with a plurality of blades attached to the lower end portion of the rotating shaft 8, and as a result, the rotating shaft 8 rotates to generate power as described above. Done.

As mentioned above, although embodiment of this invention was described, this invention is not limited to these, A various change is possible unless it deviates from the meaning of this invention.

For example, in the above-described embodiment, the support frame 3 is held on the holding frame 2 by the tension spring 6. However, the present invention is not limited to this, and a stretchable member such as rubber is used instead of the tension spring 6. You can also.

In the above embodiment, the support frame 3 is held by the holding frame 2 by the four tension springs 6, but the number of the tension springs 6 is not particularly limited. Moreover, in the said embodiment, although the support frame 3 was hold | maintained at the holding frame 2 only by the tension spring 6, it is not limited to this in particular. For example, as shown in FIG. 15, a pair of tension springs 6 are arranged to face each other via the support frame 3, and an O-shaped anchor 61 is attached to the short side wall 32 of the support frame 3, and the ring portion 611 is attached. A configuration in which the U-shaped anchor 62 penetrating through is attached to the short side wall 22 of the holding frame 2 can be employed.

Further, it is not necessary that the tension spring 6 is connected to the holding frame 2 and the support frame 3 via the

fixtures

23 and 33, and the tension spring 6 is omitted from the holding frame 2 and the support frame by omitting the

fixtures

23 and 33. 3 can also be connected directly. The tension spring 6 is attached to the

long side walls

21 and 31 of the holding frame 2 and the support frame 3, but can also be attached to the

short side walls

22 and 32.

In the above embodiment, the piezoelectric element 5 is attached only to the upper surface of the diaphragm 4, but can also be attached to the lower surface. In the above embodiment, the plurality of piezoelectric elements 5 are attached to the upper surface of the diaphragm 4, but the number of piezoelectric elements 5 may be only one.

In the above embodiment shown in FIG. 1, one diaphragm 4 is attached to each short side wall 32 of the support frame 3, but a plurality of diaphragms 4 can be attached, It can also be mounted side by side in the horizontal or vertical direction.

Further, in the power generation system 10 (FIG. 3) in the above embodiment, each support frame 3 is vibrated by a repulsive force by bringing the second magnet M2 closer to the first magnet M1 as the rotating shaft 8 rotates. For example, the second magnet M2 may be attached to a moving body that moves in a horizontal direction or a vertical direction so as to cross each power generation device 1 ′ instead of the rotating shaft 8 as a member for attaching the second magnet M2. . Also by this, when the moving body approaches, the second magnet M2 approaches the first magnet M1, and each support frame 3 can be vibrated by a repulsive force. In this case, each power generation unit 20 is preferably arranged along the moving direction of the moving body.

Further, in the power generation system 10 according to the above-described embodiment, the second magnet M2 is shifted in the circumferential direction of the rotating shaft 8 in order from the top, but the second magnet M2 is shifted in the circumferential direction of the rotating shaft 8. As long as it is present, the support frames 3 are not vibrated at the same time. Therefore, the second magnet M2 does not have to be displaced as in the arrangement of the above embodiment. If there is no problem with the driving force for rotationally driving the rotary shaft 8, the second magnet M2 may be arranged in a straight line in the axial direction of the rotary shaft 8 and the four support frames 3 may be vibrated at a time.

Further, in the power generation system 300 (FIGS. 12 and 13) in the above embodiment, the protrusions 87 are sequentially shifted from the top in the circumferential direction of the rotating shaft 8. Since the support frames 3 do not vibrate at the same time as long as they are present, the projections 87 do not have to be displaced as in the arrangement of the above embodiment. If there is no problem with the driving force for rotationally driving the rotary shaft 8, the protrusions 87 may be arranged in a straight line in the axial direction of the rotary shaft 8 and the plurality of support frames 3 may be vibrated at a time.

In the above embodiment, the

power generation systems

10 and 300 are arranged with a plurality of power generation units (power generation units 20 in the power generation system 10) in a radial manner, but there may be only one power generation unit.

In addition, the

power generation systems

10 and 300 can also have two power generation units 100 as shown in FIG. In this case, the wind pressure is detected by a sensor (pressure sensor) (not shown) that detects the wind pressure flowing in the casing 11, and if it is equal to or higher than a predetermined wind pressure, both are operated, and if less than the predetermined wind pressure, One of the electromagnetic clutches 15 can be disconnected by a control means (not shown), and only one power generation unit 100 can be operated. Instead of the sensor for detecting the wind pressure, a sensor for detecting the rotational speed of each rotating shaft 8 may be provided, and the operating number of the power generation unit 100 that operates can be controlled by this rotational speed.

In addition, as shown in FIG. 17, when a damper 16 is installed in the exhaust duct 13 of the

power generation systems

10 and 300 and the rotational speed of the rotary shaft 8 becomes too high, the damper 16 is opened and air from the intake port 121 is opened. It can also be set as the structure which reduces the inflow amount.
