On the lower surface of the buoy 112, a shaft guide portion 118 extending downward in the water direction is provided. The shaft guide portion

As shown in Fig. 13, the shaft 118 is formed in a wired shape in cross section, and a flexible shaft 119 is installed inside

have. As shown in Fig. 12, the upper end of the flexible shaft 119 is connected to the drive pulley 117,

And the drive shaft 117 is rotated by the shaft 119. In addition, the upper portion of the flexible shaft 119 is supported by a device ship

And is rotatably supported by bearings 121 provided on the teeth 113. [ As the flexible shaft 119, for example,

For example, a combination of a steel wire and a soft steel wire may be rolled up or a spring material may be rolled up. On the flexible shaft 119

The strength may be increased by inserting a wire into the center.

14, the lower portion of the flexible shaft 119 is provided with a bearing 120 provided at a lower portion of the shaft guide portion 118,

And an intermediate connecting member 47.

According to the water power generation device 110, at the water depth close to the relatively water surface, the underwater rotating body 32 swings along the water stream 11

And rotate the generator 114 via the flexible shaft 119 to generate electric power. In this embodiment

, It is employed when a water flow 11 of sufficient velocity is obtained at a position relatively close to the water surface.

15 is an enlarged partial side view showing another example of an underwater rotating body in the water-current generator of the present invention. In addition,

The same components as those in the second embodiment are denoted by the same reference numerals. The underwater rotating body (130)

The case where the body 130 is removed from the vertical member 31 and the case where the underwater rotating body 130 is quickly lifted is suitable.

As shown in the figure, a carbon dioxide cylinder 132 is installed inside the hollow body 131 of the submerged rotating body 130.

The carbon dioxide bomb 132 is provided with a spray lever 133. The spray lever 133 and the pump 133 of the drive-

And a flange 134 fixed to the connection shaft 48 is connected by a wire 135.

According to such an underwater rotating body 130, the underwater rotating body 130 is moved away from the portion of the universal joint mechanism 45,

The wire 135 is automatically cut off and the carbon dioxide gas is injected into the body part 131

The underwater rotating body 130 can be floated automatically by gas. Therefore, when the underwater rotating body 130 is rotated by the vertical member 31,

The underwater rotating body 130 drifts on the water surface 9, so that the water can be collected quickly.

When the injection lever 133 of the carbon dioxide cylinder 132 is remotely operated,

The gas within the body part 131 can be injected into the body part 131 so that the underwater rotating body 130 can float quickly. In this example

Although the carbon dioxide bomb 132 is provided in the body part 131, other gas bombs may be provided.

16 is a side view showing another example of an underwater rotating body in the water-current generator of the present invention, and Fig. 17 is a cross-

Fig. 18 is a sectional view of the wing of the underwater rotating body shown in Fig. 16. Fig. As shown in Fig. 16,

The shape of the wing 141 of the underwater rotating body 140 is different from the above example. The wing (141) is provided with a wedge

And extends to wind the outer circumference of the trunk section 142 inclined rearward at a gentle angle from the front end of the joint base section

. In this example, as shown in Fig. 17, three wings 141 are provided, and the rear end of each wing 141 is adjacent

Is extended to a position close to the engagement base portion of the wing 141. When the wing 141 is viewed from the front side

A wide wing surface 143 is formed around the trunk portion 142. The wing surface 143 is formed in the shape of a triangle. The number and shape of the vanes 141

The diameter of the body portion 142, and the like. In this example, the wings 141 are formed

So that the wing surface 143 generates a large resistance against the water stream 11. The wing surface 143 is formed by the wing surface 143, this

Even in the case where the water flow 11 is slowed down, it is possible to keep the posture of the water underwater rotating body 140 and rotate stably

All. In the underwater rotating body 140 as well, the blade 141 is fixed to the body 142 only at its front end, and between the rear body and the body 142,

So that even if the floating matter in the water adheres to the wing 141, it flows easily backward.

18, the sectional shape of the wing 141 according to the present example is such that the front surface is substantially flat and the rear surface is a streamlined

And is formed as a merchant wing section. By forming the wings 141 in such a cross-sectional shape, at the front of the wings 141

A drag force is generated and a lift force is generated at the rear surface, and the resultant combined force causes the underwater rotating body 140 to rotate in the water flow 11

And can be stably rotated.

A hollow portion 144 is formed in each wing 141. Each hollow portion 144 is short-circuited to the inside of the body portion 142

Thereby forming an independent space. A gas capable of floating the underwater rotating body 14 is inserted into each of the hollow portions 144

have. Air or the like is used as the floating gas. As described above, the hollow portion 144 is provided inside the blade 141,

(FIG. 15) by inserting air into the water rotator 144, the water rotator 140 automatically floats with water

Thereby enabling quick collection.

Fig. 19 is a perspective view showing an example of an underwater rotating body having a wing shape different from that of the underwater rotating body shown in Fig. 16. Fig. According to this example

The underwater rotating body 150 is different from the shape of the wing 141 in the underwater rotating body 140 shown in FIG. As shown

The wing 151 of the underwater rotating body 150 is located rearward at a large angle from the front end of the coupling base portion in the body portion 152

So as to extend around the outer periphery of the trunk section 152. As shown in Fig. The underwater rotating body 150 is also rotated three days

And a rear end of each wing 151 is extended to a position close to the engagement base portion of the adjacent wing 151,

And a wide blade surface 153 is formed around the trunk section 152 when viewed from the front by the wings 151. example

The wings 151 according to the exemplary embodiment are formed such that the area of the wing surface 153 is narrower than that of the wings 141,

The inclination angle at the rear is large. Even when the water flow 11 is fast due to the shape of the wings 151,

So that the entire body 150 can be stably held and rotated in a stable manner. In addition, the underwater rotating body 150 can also be mounted on the wing 151

Only the front end is fixed to the trunk section 152 and the gap between the rear section and the trunk section 152 is formed,

So that it is easy to flow backward. It is possible to use a wing surface 153 having a narrow area as in this example,

It is preferable to make the wings 143 having a wider width as the wings 141 are determined according to the conditions of use such as the speed of the water flow 11

All.
