〔産業上の利用分野〕
本発明は河川、海などの底に配設することで、その流体
エネルギーによシ発電機を作動させ、これによシミ気エ
ネルギーを得ようとする発電装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is arranged at the bottom of a river, the sea, etc., and uses the fluid energy to operate a generator, thereby obtaining stain energy. The present invention relates to a power generation device that is intended to
既に、海流などを利用して発電するため、第５図に示す
如く、枠体ａ内にプロペラｂ付きの発電ｉｃを内装固設
したものがあシ、これは海底ｄなどに載設して用いられ
ている。As shown in Figure 5, there is already a system in which a power generating IC with a propeller b is fixed inside a frame body a, as shown in Figure 5, in order to generate electricity using ocean currents. It is used.
ところが海流ｅが矢印のように、プロペラｂに対して正
面から直交状に指向しているときは、充分にプロペラｂ
が回転して所望の電力を得ることができるが、当該海流
ｅの方向が変化してしまうと、発電機の出力は急激に低
減してしまい、このため充分な電力量が得られないだけ
でなく、その用途も自ら限定されてしまう欠陥があった
。However, when the ocean current e is directed perpendicularly to the propeller b, as shown by the arrow, the propeller b is sufficiently
can rotate and obtain the desired electric power, but if the direction of the ocean current e changes, the output of the generator will suddenly decrease, and as a result, sufficient electric power will not be obtained. However, there was a flaw in that its use was limited by itself.
そこで、第６図のように前記枠体ａに方向舵ｆを付し、
これを回転基台ｇ上に回転自在なるよう軸承することで
、海流ｅの方向変化に追随できるようにすることも考え
られるが、回転基台ｇは重い発電機Ｃを含む大きな荷重

久性にも問題があるだけでなく、プロペラｂを流体にて
回転させる機構であるため、基本的に海流ｅ等の流速が
小さいと、当該プロペラＣが回らず、電気出力が零とな
ってしまう欠陥がある。Therefore, as shown in FIG. 6, a rudder f is attached to the frame a,
It may be possible to support this on a rotary base g so that it can rotate freely, so that it can follow changes in the direction of the ocean current e, but since the rotary base g is subject to a large load including the heavy generator C. , The multiple movements of the head to change direction became unsmooth, and the direction could not be changed in low-speed ocean currents.Not only was there a problem with the durability of the rotating parts, but propeller b was rotated by fluid. Since it is a mechanism, it basically has a defect that if the current speed of the ocean current e is low, the propeller C will not rotate and the electrical output will become zero.
本発明は、上記従来のプロペラ式発電装置の難点に鑑み

うな方向からの流体にも、上記カルマン回転部の往復運
動を確保させ、これによって微小流速時。In view of the drawbacks of the conventional propeller-type power generation device, the present invention provides a configuration that can effectively utilize the phenomenon of Karman vortex generation in fluid, thereby reliably converting the energy of low-speed fluid into electrical energy. The Karman rotating section smoothly follows the change in direction of the fluid to ensure reciprocating motion of the Karman rotating section even when the fluid is flowing from any direction, thereby ensuring the reciprocating motion of the Karman rotating section at minute flow velocities.
にも発電し、しかも流体変向に際しても効率のよい発電

の発電容量を大きくしたシ、小さくしたシすることもで
きるようにし、もって需要に対応した適切な発電を可能
にしようとするものである。In addition to making it possible to generate electricity efficiently even when changing fluid direction, we also made it possible to increase or decrease the generation capacity extremely easily, thereby responding to demand. The aim is to enable appropriate power generation.
本発明は上記の目的を達成するため、基体に設けた発電
機には、その回転部に回転力を・伝達可能なるよう可視
性カルマンロープを連結し、当該可読性カルマンロープ
の自由端側には浮子を連結する構成としたものである。In order to achieve the above object, the present invention connects a visible Karman rope to the generator provided on the base so that rotational force can be transmitted to the rotating part of the generator, and the free end side of the readable Karman rope is connected to the generator provided on the base. It has a structure in which floats are connected.

とを連結するようにしている。Furthermore, in the present invention, a visible Karman rope 3 made of wire rope or the like is prepared, and a float 4 and the above-mentioned rotating shaft 2a are connected to the upper and lower ends of the rope 3, respectively. In the embodiment shown in FIG. 1, a connecting rod 5a is connected to the lower end of the rope 3 so that the rope 3 can bend freely and transmit rotational force to the rotating shaft 2a. A suitable universal joint 5 is constructed using the portion 5a, and the rope 3 and the rotating shaft 2a are connected via the joint 6, that is, the universal joint.
I am trying to connect them.

Even if the connecting seat plate 7 is connected and the square column part 2b is fitted into the square hole 7a of the plate 7, the retaining dowel 8 is penetrated and locked into the square hole 7a of the plate 7, and the flexibility described later is not achieved. The movement of the Karmann rope 3 can be transmitted as the rotational force of the rotating shaft 2a, and the rope 3 can also be freely deformed.

ることとなる。When the above-mentioned device is placed in the sea as shown in Figure 1, the flexible Karman rope 3 will be moved vertically due to the buoyancy of the float 4, as shown by the imaginary line in the figure when there is no ocean current. However, when liquid A such as seawater is flowing in the direction of the arrow in Figure 2 of Oni 1, the flexible Karman rope 3 curves toward the downstream side as shown by the solid line. As the rope 3 shifts, a known Karman vortex is generated on the downstream side of the rope 3 at predetermined intervals as shown in FIG. It will reciprocate within the rotation angle range, so the rotating shaft 2a will be rotated left and right by the rotational force of the rope 3.
As a result, the rotating part of the generator 2 is rotated to the left and to the right, so that corresponding electric power is obtained at the output terminal of the generator 2.

If the generator 3 has a built-in electric means (not shown), for example, a phase converter, the above-mentioned left and right reciprocating motion can be converted into continuous rotational power in one direction with respect to the rotating shaft 2a. A transmission mechanism may be provided.

作にて、発電容量を自由に調整することもで′きる。Since the present invention can be realized as in the above-described embodiments and configured as described above, even with the kinetic energy of the liquid at a low flow rate, the flexible Karman rope 3 can be efficiently reciprocated by the Karman vortex. Since it can be moved, it is not only possible to generate a considerable amount of power even with minute flow velocities, but also because it can move freely to follow the change in direction of the liquid flow, it can be easily adjusted to any change in flow direction. Following this, the maximum power generation output can always be obtained, and the generator is fixed at a suitable location on the base 1, so that its load does not affect the reciprocating movement of the Power Le Man Rogue 3. It is excellent in terms of power generation efficiency and durability, and furthermore, according to the present invention, since the flexible Karman rope 3 is connected between the float 4 and the rotating part of the generator 2, the length of the rope 3 is It is also possible to freely adjust the power generation capacity by adjusting the amount as appropriate.
