DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the power generation system of the present invention will be described in more detail based on examples. 1 to 4 are diagrams showing an embodiment of a power generation system according to the present invention. FIG. 1 is a front view, FIG. 2 is a plan view, FIG. 3 is an XX sectional view, and FIG. 4 is a YY sectional view. FIG.
[0008]
As shown in FIG. 1, the power generation system of the present embodiment includes a main tower 2 that rotatably holds a rotor 1 (1A to 1C), and an annular coaster belt 3 (3A to 3C) that rotationally drives the rotor 1. And a coaster tower 4 installed.
[0009]
The coaster tower 4 is a structure that is elongated in the vertical direction, and arms 5 and 6 are provided at the upper end portion and the middle portion in the longitudinal direction so as to extend toward the main tower 2 side. Shafts 7 and 8 are horizontally arranged at the distal ends of the arms 5 and 6, respectively. The shaft 7 of the upper arm 5 is an input shaft, and the shaft 8 of the lower arm 6 is a holding shaft. I will call it.
[0010]
The input shaft 7 and the holding shaft 8 are provided with sprocket wheels 9 and 10 through a rolling bearing such as a ball bearing at a plurality of positions in the axial direction so as to correspond to each other. At this time, at least the upper wheel 9 is provided so as to allow only forward rotation (rotation in the counterclockwise direction in FIG. 1). For this, a ratchet mechanism or the like may be used, but it is desirable to use a one-way ball bearing.
[0011]
This one-way ball bearing is such that the outer ring can rotate only in one direction with respect to the inner ring. For example, “Cam Clutch” BB series manufactured by Enomoto Enoson Co., Ltd. can be used. In this embodiment, the upper wheel 9 is provided on the input shaft 7 via a one-way ball bearing, while the lower wheel 10 is provided on the holding shaft 8 via a normal ball bearing.
[0012]
The number of sprocket wheels 9 and 10 provided in each axial direction of the input shaft 7 and the holding shaft 8 is appropriately set. In this embodiment, three sprocket wheels are provided at equal intervals in the axial direction. As a result, three pairs are established between the sprocket wheel 9 of the input shaft 7 and the sprocket wheel 10 of the holding shaft 8 corresponding thereto.
[0013]
Then, between the sprocket wheels 9, 10 corresponding to the input shaft 7 and the holding shaft 8, a conveying rod chain is wound around as a coaster belt 3. As a result, the coaster belt 3 can rotate around the upper and lower sprocket wheels 9 and 10 and can only rotate forward by the action of the one-way ball bearing.
[0014]
The annular coaster belt 3 is provided with an operating material 11 (11A to 11C) that protrudes outward from the coaster belt 3 at least in one circumferential direction. The working material 11 of the present embodiment extends substantially perpendicularly outward with respect to the belt surface of the coaster belt 3, and a roller is rotatably provided at the tip portion thereof. This roller is rotatable on an axis along a direction parallel to the input shaft 7 and the holding shaft 8.
[0015]
The coaster belt 3 is provided with a weight 12 that facilitates movement of the coaster belt 3 when the working material 11 descends from the input shaft 7 side to the holding shaft 8 side in the vicinity of the working material 11. When the working material 11 has a sufficient weight, it can be said that the weight 12 is unnecessary, but it is not preferable to provide a concentrated load at one place of the coaster belt 3, so the coaster belt is adjacent to the working material 11. It is desirable to provide the weight 12 by a desired length along the longitudinal direction of 3. In FIG. 1, only the weight 12 with respect to the working material 11A of the near side coaster belt 3A is shown, and the weights of the other coaster belts 3B and 3C (the working materials 11B and 11C) are not shown. .
[0016]
The weight 12 is provided on either one or both sides of the working material 11. In the present embodiment, as shown in FIG. 1, the working material 11 is provided behind (clockwise). In the illustrated example, each coaster belt 3 is provided with only one working material 11, but a plurality may be provided. For example, the working materials 11 and 11 may be provided before and after the weight 12 so as to sandwich the weight 12 of the coaster belt 3. In some cases, a plurality of working materials 11 having such weights 12 arranged adjacent to each other may be provided at equal intervals in the circumferential direction of the coaster belt 3.
[0017]
As shown in FIGS. 2 and 3, the input shaft 7 includes, in addition to the sprocket wheels 9 for the coaster belt 3, two first and second wheels (sprocket wheels and the like) 13 for rotational driving, 14 is provided. The first wheel 13 is driven by a prime mover 15, and the second wheel 14 is rotationally driven by returning the rotational force of the rotor 1 as described later. These wheels 13 and 14 are provided at one end of the input shaft 7.
[0018]
The first wheel 9 of the input shaft 7 can be rotationally driven by the prime mover 15. In this embodiment, a wheel 15 b is fixed to the output shaft 15 a of the prime mover 15 (FIG. 2), and the wheel 15 b and the first wheel 13 are connected by a rotational drive belt 16. Accordingly, the rotational force of the output shaft 15 a of the prime mover 15 is transmitted to the input shaft 7 via the rotational drive belt 16. A space between the output shaft 15a of the prime mover 15 and the sprocket wheel 15b provided on the output shaft 15 is provided through the one-way ball bearing so that only normal rotation is possible. The rotational drive of the input shaft 7 by the prime mover 15 is not limited to the belt, and may be performed by, for example, a gear train.
[0019]
The main tower 2 is an elongated structure in the vertical direction, and an output shaft 17 is held in a horizontal state at an upper end portion thereof. The output shaft 17 is arranged in parallel with the input shaft 7 and the holding shaft 8. The rotor 1 (1A to 1C) is attached to the output shaft 17. In addition, a generator 30 is connected to the output shaft 17 so that power can be generated as the output shaft 17 rotates. A speed increaser (not shown) or the like may be appropriately interposed between the output shaft 17 and the generator 30.
[0020]
The rotor 1 (1A to 1C) is provided at a plurality of positions in the axial direction of the output shaft 17, and the mounting positions thereof are positions corresponding to the respective coaster belts 3 (3A to 3C). Therefore, in this embodiment, the three rotors 1A to 1C are provided on the output shaft 17 in correspondence with the three coaster belts 3A to 3C. Each rotor 1 is provided with a rod bar 18 extending outward in the radial direction of the output shaft 17. The length of each rod bar 18 is common, and when the working material 11 descends the coaster belt 3, the rod bar 18 needs to be long enough to hit the working material 11. Therefore, the rod bar 18 and thus the rotor 1 can be rotated while being pushed downward by the working material 11.
[0021]
The number of rod bars 18 of each rotor 1 is set as appropriate. When a plurality of rod bars 18 are provided in one rotor 1, the rod bars 18 are preferably provided at equal intervals in the circumferential direction of the rotor 1. Further, in the case where one actuating material 11 that substantially operates is provided on each coaster belt 3, the number of rod bars 18 of each rotor 1 is set so as not to be an integral multiple of the number of coaster belts 3. This is to prevent the rod bar 18 from being pushed down by the working material 11 during the rotation operation in parallel with all the coaster belts 3A to 3C and the rotors 1A to 1C.
[0022]
Therefore, in this embodiment, since the coaster belt 3 has three rows, the number of rod bars 18 of each rotor 1 is preferably set to 2 or 4 or the like. Moreover, the rotor 1 corresponding to each coaster belt 3 is placed on the rod 11 in the corresponding working material 11 of the coaster belt 3 in a state where the working material 11 is shifted in the circumferential direction between the coaster belts 3, 3. It is arranged at a position where it hits and rotates. By doing so, a smooth operation similar to that of hydroelectric power generation can be expected if the balance is maintained.
[0023]
The rotation of the output shaft 17 due to the rotation of the rotor 1 can be transmitted to the input shaft 7. In the present embodiment, as shown in FIG. 1, the first gear 20 connected to the output shaft 17 via the belt 19 and the second gear 22 connected to the input shaft 7 via the belt 21 similarly to this. Are provided so that the presence or absence of mutual engagement can be changed. Thus, if the first gear 20 and the second gear 22 are engaged with each other, the rotation direction of the output shaft 17 is originally opposite to that of the input shaft 7, but the rotation direction is reversed by the engagement of the gears 20 and 22. Can be transmitted to the input shaft 7. That is, the rotation of the first gear 20 that is rotationally driven by the output shaft 17 is reversed in the rotation direction by the second gear 22 meshing with the first gear 20, and the rotation of the second gear 22 is input via the belt 21 and the second wheel 14. The shaft 7 can be rotated forward.
[0024]
In the illustrated example, the engagement of the first gear 20 and the second gear 22 can be released by separating the first gear 20 from the second gear 22. That is, in the present embodiment, the first base 23 including the first gear 20 is movable along the rail 25 with respect to the second base 24 including the second gear 22. The movement is performed by, for example, expansion and contraction of the rod 26a of the cylinder 26 installed on the second base 24.
[0025]
Incidentally, the second base 24 is provided not only with the second gear tower 27 holding the second gear 22 but also with the motor 15 and the coaster tower 4 provided with the coaster belt 3 driven thereby. The second gear 22 may be attached to an arm provided in the coaster tower 4 without providing the second gear tower 27.
[0026]
In addition, the first base 23 is provided with not only the first gear tower 28 that holds the first gear 20 but also the main tower 2 including the rotor 1. Further, a generator 30 may be installed. The first gear 20 may be attached to the arm provided in the main tower 2 without providing the first gear tower 28.
[0027]
By the way, the foundations 23 and 24 are formed with a substantially semicircular digging portion 29 at a position where the tip of the rod bar 18 passes when the rotor 1 rotates. As a result, the height of the main tower 2 can be kept low, and therefore the electricity from the generator 30 can be taken out at a height as close to the ground as possible.
[0028]
Next, the operation of the power generation system of the above embodiment will be described.
At the time of operation, the operation materials 11 of the coaster belts 3 are arranged to be staggered.
[0029]
The rod bars 18 are also arranged at equal intervals in the circumferential direction so as to be alternated between the rotors 1. In the illustrated example, three rotors 1 having two rod bars 18 and 18 at 180 ° intervals are provided, so that the rod bars 18 of the three rotors 1 (1A to 1C) are arranged every 60 °. .
[0030]
In addition, when the operating material 11 of each coaster belt 3 descends from the input shaft 7 to the holding shaft 8 side, both the rotor 1 and the coaster belt 3 contact with the rod bar 18 of the rotor 1 corresponding to the coaster belt 3. Each position is adjusted.
[0031]
First, when the prime mover 15 is driven, the input shaft 7 is rotated accordingly. Since the sprocket wheel 9 is provided on the input shaft 7 via a one-way ball bearing, and the coaster belt 3 made of a chain is wound around the wheel 9, the coaster belt 3 can only rotate forward. Therefore, when the operating material 11 climbs from the holding shaft 8 to the input shaft 7 side, the reverse rotation is prevented by the unidirectional ball bearing, and the working material 11 is wound upward as the input shaft 7 rotates.
[0032]
However, the working material 11 that has gone up to the wheel 9 of the input shaft 7 also has the effect of the weight 12 provided adjacent thereto, and when its center of gravity comes to the downside of the coaster belt 3, it is lowered downward at a stretch by gravity. Will go down. At this time, the one-way ball bearing functions as a mere ball bearing because it rotates on the forward rotation side. Therefore, the coaster belt 3 performs fast forward rotation, and the working material 11 runs down at a stretch. The working material 11 that has run down to the side of the holding shaft 8 rotates around the holding shaft 8 with the momentum, and runs up the coaster belt 3 slightly upward. For example, the height of the coaster belt 3 (the separation distance between the input shaft 7 and the holding shaft 8) is about one third.
[0033]
When the working material 11 falls at a stroke, the working material 11 hits the corresponding rod bar 18 and pushes the rod bar 18 downward. Then, the rotor 1 and consequently the output shaft 17 are rotated, and power is generated by the generator 30 connected to the output shaft 17.
[0034]
In addition, when the working material 11 is lowered, it is preferable that the working material 11 hits the rod bar 18 for as long a distance and time as possible. For this purpose, each member is positioned in consideration of increasing the longitudinal dimension of the rod bar 18 and the working material 11, or taking into consideration the rotating track at the tip of the rod bar 18 and the rotating track at the tip of the working material 11. For example, as shown in FIG. 1, the coaster belt 3 is preferably provided so as to be inclined away from the output shaft 17 as it goes downward. That is, the holding shaft 8 is arranged on the right side in FIG.
[0035]
When the working material 11 falls downward and the rod bar 18 is pushed down and rotated accordingly, the rotor 1 rotates. Then, the rotation rotates the input shaft 7 via the first gear 20 and the second gear 22. Accordingly, as the rod 1 is pushed down by a certain actuating material 11 and the rotor 1 is rotated, the actuating material 11 of the next coaster belt 3 and the rod bar 18 are arranged at corresponding positions. Similarly, the working material 11 pushes down the rod bar 18 downward.
[0036]
In this manner, the rod bars 18 of the rotors 1 are sequentially rotated by the working members 11 of the coaster belts 3. And thereby, the rotor 1 rotates smoothly. The rotational force of the rotor 1 is not only used for power generation by the generator 30 as described above, but can also be reused for driving the input shaft 7 via the first gear 20 and the second gear 22. Yes.
[0037]
Therefore, after the rotor 1 rotates smoothly, the system continues to operate even if the driving of the prime mover 15 is stopped for some time. Therefore, if the motor (temporarily battery-powered direct current 1/20 gear mode speed change motor or inverter) 15 is used and a predetermined rotation is obtained by accelerating slowly from a low speed, the power may be turned off using a sensor or the like. Is possible. That is, for example, the rotational speed (the number of rotations) of the input shaft 7 is measured, and if it becomes a certain value or more, the driving of the prime mover 15 is stopped, and if it becomes a certain value or less, it can be controlled to operate the prime mover 15 again. This is expected to improve power generation efficiency.
[0038]
In order to stop the movement of the system, the prime mover 15 is stopped and the first base 23 is slid with respect to the second base 24 to release the engagement between the first gear 20 and the second gear 22. .
[0039]
The system of the above embodiment comprises a main tower 2 with a rotor 1 and a coaster tower 4 with a coaster belt 3. In other words, it is like integrating a Ferris wheel and a roller coaster, and it can be said to have docked wind power generation and pumped hydropower generation.
[0040]
The principle is that the rod bar 18 is rotationally driven by the working material 11 descending the coaster tower 4. This is an application of Isogo and the use of gravity. Such a principle is made possible by using a one-way ball bearing for the starting portion to suppress the antigravity motion when the actuating member 11 is rolled up.
[0041]
By using unidirectional ball bearings for the rotating parts of the prime mover 15 and the coaster belt 3, even if there is a difference in speed between the prime mover 15, the coaster belt 3, and the rotor 1, it can be absorbed.
[0042]
In addition, compared to other power generation methods, it is possible to realize economic efficiency and extremely low pollution because the location point is close to the consumption area and the size can be reduced.
Furthermore, facilities for adjusting voltage fluctuations, such as those found in wind power generation, are also unnecessary.
[0043]
Note that the power generation system of the present invention is not limited to the configuration of the above embodiment, and can be changed as appropriate.
In particular, the number of coaster belts 3 and rotors 1, the number of operating members 11 installed on each coaster belt 3, and the number of rod bars 18 installed on each rotor 1 can be changed as appropriate. However, at that time, each working material 11 of each coaster belt 3 and each rod bar 18 of each rotor 1 sequentially correspond to each other, and the working material 11 and the rod bar 18 are disposed at a position where the rotor 1 is smoothly rotated.
[0044]
In the above embodiment, a rod chain or the like is used for transmitting the power of each part, but it goes without saying that a gear train, a belt transmission, or the like can be used depending on the place or load. Correspondingly, for example, such a change that the wheel is replaced with a pulley instead of the sprocket wheel is natural.
[0045]
【The invention's effect】
As described above in detail, according to the power generation system of the present invention, it is possible to generate power with somewhat improved power generation efficiency compared to the conventional one.
