Reference numeral 13 denotes a control unit that controls the flow of electricity generated by the generator 5.

  The control unit 13 includes a microcomputer, a transformer, a signal input / output device, and the like. The generator 5 and the motor 4a of the device of the present invention are electrically connected to the control unit 13 together with the storage battery 11 and the electric device 12.

Specifically, it is provided on the rear side of the operating body 3 so as to stand higher than the operating body 3.

  The torque reinforcing member 16 is formed of a metal wire material in this embodiment. Specifically, it is formed of a wire having a large diameter. The lower part of the wire as the metal linear material is wound and formed in a wound portion 16a that absorbs an impact when it hits the rod-shaped member 14.

  Therefore, in the case of the present invention of this embodiment, when the torque reinforcing member 16 hits the rod-shaped member 14, the impact is weakened by the elasticity of the coil spring, and the impact at the time of collision is reduced by the contraction and restoration action of the winding portion 16a.

Next, the operation of the device of the present invention will be described.
First, when the motor 4a of the operating device 4 is driven, the operating body 3 moves along with the transmission member 4b in the horizontal direction in the circumferential direction and circulates. Therefore, in the case of the present invention, the water in the flow path 1 is washed away by the operating body 3, the water pressure is increased, and the blade 2a of the water turbine 2 is rotated by this water.

  In this case, since a plurality of the operating bodies 3 are accommodated in the flow path 1, each operating body 3 sequentially applies water pressure to each water turbine 2 while circulating in the flow path 1. As a result, the water turbine 2 rotates with a large force, and the generator 5 connected to the water turbine 2 converts the pressure energy of the water into electrical energy.

  Thus, since the storage battery 11 is normally connected to the apparatus of the present invention, the electricity generated by the generator 5 is charged to the storage battery 11 as shown in FIG. For example, when the electric device 12 is switched on in a state where the charging amount is 100%, the electric device 12 is discharged by receiving a signal from the control unit 13 and is supplied with power.

In this embodiment, the battery 11 is discharged until the remaining amount of the storage battery 11 reaches 30% (see FIG. 9). When the remaining amount reaches 30%, a drive signal is sent from the control unit 13 to the motor 4a. To drive. As a result, the operating body 3 circulates, the water turbine 2 rotates, and the generator 5 generates power. The generated electricity is charged in the storage battery 11.
Such power generation and charging operations are automatically and periodically performed by a program incorporated in the microcomputer of the control unit 13.

  In addition, the apparatus of this invention may be integrated in the middle of the water supply water pipe, for example, and it may be formed so that tap water can be supplied to the flow path 1. In this case, the replacement of water can be omitted, and the water pressure of tap water can be used for the circulation operation of the operating body 3, so that power generation can be performed more efficiently.

  The installation location of the apparatus of the present invention includes, for example, under the eaves, in the garden, or adjacent to electricity demand. The apparatus of the present invention can also be used by being mounted on an electric vehicle, for example, as a power source for the electric vehicle. In this case, it is preferable that a program is set in the control unit 13 to automatically generate and charge when the vehicle is parked and the engine key is removed. According to this, the use as an alternative apparatus of the existing charging equipment stand is attained.

  In the above process, according to the present invention, as shown in FIG. 10 and FIG. 11, the torque reinforcing member 16 is arranged upright in the front-and-rear direction at the position 7 c of the transmission member 4 b disposed in the flow path 1. It may be provided. The same parts as those in the above example are denoted by the same reference numerals, and detailed description thereof is omitted.

In this case, the front torque reinforcing member 16 hits the rod-shaped member 14 first, and then the rear torque reinforcing member 16 hits the rod-shaped member 14 and sequentially applies a rotational force to the blades 2a of the turbine 2.
Therefore, according to this, the rotational force can be further increased. Further, according to this, it is possible to expect an effect that the collision sounds of the front and rear torque reinforcing members 16 interfere with each other and weaken each other.

  Moreover, in the case of this invention, the shape, material, etc. of said torque reinforcement member 16 and rod-shaped member 14 are arbitrary, and are not limited to the above example.
