に関する。[Detailed Description of the Invention] <<Industrial Application Field>> The present invention can be installed on the bottom of a river, sea, etc.
The present invention relates to a power generation device that uses the fluid energy to operate a generator and thereby obtain electrical energy.
≪従来の技術≫
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
機ｃを内装固設したものがあり、これは海底ｄな
どに載置して用いられている。≪Conventional technology≫ Already, the 5th technology uses ocean currents to generate electricity.
As shown in the figure, there is a system in which a generator c with a propeller b is fixed inside a frame a, and this is used by being placed on the seabed d or the like.
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流を得ること
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、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つた。 However, when the ocean current e is oriented perpendicular to the front of the propeller b as shown by the arrow, the propeller b can rotate sufficiently to obtain the desired current, but the direction of the ocean current e is If this happens, the output of the generator will drop rapidly, which not only makes it impossible to obtain a sufficient amount of electricity, but also limits its use.
そこで、第５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

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
出力が零となつてしまう欠陥がある。 Therefore, as shown in FIG. 5, the rudder f is attached to the frame a.
It is conceivable that the rotary base g could be attached to a rotary base g and rotatably supported on a shaft so that it could follow changes in the direction of the ocean current e. Due to the load, the swinging motion for changing direction becomes unsmooth, and the direction may not be changed in low-speed ocean currents.Not only is there a problem with the durability of the rotating parts, but propeller b is Since it is a rotating mechanism, basically, if the current speed of the ocean current e is low, the propeller c will not rotate and the electric output will become zero.

A lower end of the flexible rope is connected to the lower end of the flexible rope, and a float is connected to the upper end of the flexible rope, which is the free end side extending from the base body, so that the flexible rope can be suspended in the liquid flow. However, due to the Karman vortex that occurs downstream,
An attempt is made to provide a power generation device that is installed in a liquid and is characterized by being able to reciprocate in a direction perpendicular to the axial direction.

In the embodiment shown in FIG. 1, the flexible rope 3 is connected to a A connecting rod 5a is connected to the lower end of the rope 3, and the rod 5a is used to configure a suitable universal joint 5, and the flexible rope 3 and the rotating shaft are connected via the universal joint 5, that is, the universal joint. 2a are connected.
そして、さらに当該実施例では前記の浮子４と

The karma vortex allows the flexible rope 3 to be efficiently reciprocated in a direction perpendicular to its axial direction, which not only makes it possible to generate a considerable amount of power even with a minute flow velocity, but also allows the flexible rope 3 to sex rope 3
is movable to follow the change in the direction of the liquid flow, so it can follow any change in the flow direction and always obtain the maximum power generation output, and the generator can be fixed at a suitable location on the base 1. Since the load does not affect the reciprocating motion of the flexible rope 3, the power generation efficiency and durability are also excellent. Furthermore, according to the invention, the flexible rope 3
is connected between the float 4 and the rotating part of the generator 2, so the power generation capacity can be freely adjusted by extremely easy operations such as adjusting the length of the flexible rope 3 as appropriate. You can also do that.
