[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-82386 Summary of the Invention [Problem to be solved by the invention]

[0004] A typical structure of a conventional generator includes a coil formed by winding a conductor, a magnet placed close to the coil, a rotating shaft fixed to the center of the coil, and a drive means for rotating the rotating shaft, and generates electrical energy through electromagnetic induction between the coil and the magnet. The rotating shaft attached to the magnet is connected to the drive means, and the current generated by electromagnetic induction between the magnet rotated between the coil and the coil by the drive means flows through the conductor connected to the coil to, for example, a storage battery and is stored there. Conventionally, it is important for such generators to ensure that the rotation of the magnets is efficient. The present invention has been made in light of the above circumstances, and provides a hydraulic generator with a novel structure that uses the force of water (water pressure) to turn a wind turbine and generate electricity efficiently underwater. [Means for solving the problem]

[0005] The hydraulic generator with a wind turbine of the present invention is a generator that obtains electrical energy through electromagnetic induction between a coil and a magnet, and includes a rotating shaft that drives the coil or the magnet, and further includes a rotating shaft drive unit consisting of a pair of bellows pump chambers and a wind turbine that is disposed between the pair of bellows pump chambers and installed inside the wind turbine chamber to which the rotating shaft is connected, a lower part of one of the bellows pump chambers is connected to an upper end of one of the wind turbine chambers via a connector such as a pipe, and the other upper end of the wind turbine chamber is connected to the lower part of the other bellows pump chamber by a connector such as a pipe, and a drain tower and a sliding door are provided at the upper ends of the pair of bellows pump chambers, respectively, and one of the sliding doors is configured so that when the other is open the other closes, and the wind turbine chamber is further provided with a pair of switching point plates that have switching points that change the air flow inside the chamber. In a generator configured as described above, the rotary shaft drive unit is placed underwater together with the generator. The sliding door of one bellows pump chamber is open, and the sliding door of the other bellows pump chamber is closed. Water enters one of the bellows pump chambers through the opening, compressing the air with its water pressure, generating an air flow. For example, as shown in FIG. 1, if the switching point plate is tilted upward and the air flows from right to left below the wind turbine, the wind turbine rotates as indicated by the thick arrow in the figure, and the rotary shaft connected to the wind turbine also rotates in the same manner. For example, if the switching point plate is tilted downward and the air flows from left to right above the wind turbine, as shown in FIG. 2, the wind turbine also rotates as indicated by the thick arrow in the figure, and the rotary shaft connected to the wind turbine also rotates in the same manner. In this way, by correctly matching the opening and closing timing of the sliding door with the switching timing of the switching point plate, the wind turbine rotates in a fixed direction, and the rotating shaft connected to the wind turbine rotates in accordance with the rotation of the wind turbine, so that the water pressure generator using this wind turbine functions effectively. [Effects of the Invention]

[0006] The hydraulic generator using the wind turbine of the present invention has a rotating shaft drive unit with a novel structure in which the rotating shaft is rotated by the force of water (water pressure), and has good power generation efficiency. [Brief explanation of the drawings]

[0008] Hereinafter, the mode for carrying out the invention will be described with reference to examples. [Example]

[0009] The first embodiment will be described with reference to FIGS. A generator is a device that obtains electrical energy through the electromagnetic induction effect between a coil and a magnet. Electromagnetic induction is the phenomenon in which an electric current is generated in a conductor by moving the conductor in a magnetic field. There are various types of generators, such as those used in bicycles, which generate electricity continuously through electromagnetic induction by rotating a magnet inside a coil (conductor), and those in which a coil rotates in a magnetic field, and the rotating shaft is an important element of these generators.

[0010] The generator of this embodiment has a part of the rotating shaft 1 that drives the coil or magnet inside the generator 10 (generator body), and further has a rotating shaft drive unit that has a pair of bellows pump chambers 21, 22, a wind turbine 3 housed in a wind turbine chamber 100, and a pair of switching point plates 31, 32 that are arranged inside the wind turbine chamber 100 and change the air flow (wind current) generated by water pressure (see Figures 1 to 3). In the pair of bellows pump chambers 21, 22, the lower part of one of the bellows pump chambers 22 is connected to one upper end of the wind turbine chamber 100 via a connecting part 42 such as a pipe, and the other upper end of the wind turbine chamber 100 is connected to the lower part of the other bellows pump chamber 21 by a connecting part 41 such as a pipe. Inside the wind turbine chamber 100, a wind turbine 3 is arranged, with multiple blades attached around a wind turbine rotation shaft (not shown), which is connected to a rotation shaft 1 of a generator 10. Therefore, as the wind turbine 3 rotates, the rotation shaft 1 rotates, and accordingly the generator 10 generates electricity (see Figures 4 and 5).

[0011] In a generator configured as described above, the rotary shaft drive unit is placed underwater together with the generator. At this time, the sliding door 26 of one bellows pump chamber 22 is open, and the sliding door 25 of the other bellows pump chamber 21 is closed. Water enters one bellows pump chamber 22 through the opening 27, and the water pressure compresses the air, generating an air flow (see FIG. 1). At this time, as shown in FIG. 1, for example, the switching point plates 31 and 32 are tilted upward so that this air flow (wind current) flows from right to left below the wind turbine. With this arrangement, the wind turbine 3 rotates as indicated by the thick arrow in the figure, and therefore the rotating shaft 1 of the generator connected to the wind turbine 3 also rotates in the same manner. Next, as shown in Figure 2, the switching point plates 31 and 32 are tilted downward so that the current flows from left to right above the wind turbine 3. Even when this is done, the wind turbine 3 still rotates as indicated by the thick arrow in the figure, and ultimately the rotating shaft 1 connected to the wind turbine 3 also rotates in the same way.

[0012] By correctly matching the opening and closing timing of the sliding doors 25, 26 configured in this manner with the switching timing of the switching point plates 31, 32, the wind turbine 3 rotates in a fixed direction, and the rotating shaft 1 connected to the wind turbine 3 rotates in accordance with the rotation of the wind turbine 3, so that the water pressure generator 10 using this wind turbine 3 functions effectively (generates electricity). Figure 3 is a perspective view of a hydraulic generator having a wind turbine of an embodiment installed underwater. The generator 1 is adjacent to a wind turbine chamber 100, which is installed between a pair of bellows pump chambers 21 and 22. In the figure, drainage towers 23 and 24 are configured to be exposed above the water surface 12 and discharge water pushed out by water pressure to the outside. [Explanation of symbols]
