Summary of the Invention

Problems to be Solved by the Invention

[0004] A general structure in a conventional generator includes a coil formed by winding a wire, a magnet disposed in proximity to the coil, a rotating shaft fixed to the center of the coil, and a driving means for rotationally driving the rotating shaft. Electric energy is obtained by the electromagnetic induction action between the coil and the magnet. The rotating shaft attached to the magnet is connected to the driving means, and by this driving means, the current generated by the electromagnetic induction action between the magnet rotated between the coils and the coil flows through a wire connected to the coil and is stored in, for example, a storage battery. Conventionally, it has been important to rotate the magnet efficiently in such a generator. The present invention has been made under such circumstances, and provides a hydraulic generator having a novel structure in which a windmill is rotated by utilizing the force (water pressure) of water, and efficient power generation is performed underwater.

Means for Solving the Problems

[0005] The hydraulic generator having a windmill according to the present invention is a generator that obtains electrical energy by the electromagnetic induction action of a coil and a magnet, and includes a rotating shaft that drives the coil or the magnet. Further, it includes a pair of bellows pump chambers and a rotating shaft drive unit including a windmill installed in a windmill chamber disposed between the pair of bellows pump chambers and connected to the rotating shaft. The lower part of one bellows pump chamber is connected to one upper end of the windmill chamber Connecting part made of pipe via, and the other upper end of the windmill chamber is connected to the lower part of the other bellows pump chamber Connecting part made of pipe by. Drain towers and slide doors are respectively provided at the upper ends of the pair of bellows pump chambers. The slide doors are configured such that when one is open, the other is closed. Further, the windmill chamber includes a pair of switching point plates having switching points for changing the air flow inside the chamber. In a generator having such a configuration, the rotating shaft drive unit is installed underwater together with the generator. At this time, the slide door of one bellows pump chamber is open, and the slide door of the other bellows pump chamber is closed. Then, water enters one bellows pump chamber from the opening of the open part, compresses air with its water pressure, and generates an air flow. And this air flow (wind flow) is, for example, as shown in FIG. 1, the switching point plate is tilted upward, and the air flow is treated so as to flow from right to left under the windmill. Therefore, the windmill rotates as shown by the thick arrow in the figure, and the rotating shaft connected to the windmill also rotates in the same way. Also, for example, as shown in FIG. 2, when the switching point plate is tilted downward and the air is treated so as to flow from left to right above the windmill, the windmill rotates as shown by the thick arrow in the figure, and the rotating shaft connected to the windmill also rotates in the same way. 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 windmill rotates in a fixed direction, and the rotating shaft connected to the windmill rotates according to the rotation of the windmill. Therefore, the hydraulic generator using this windmill functions effectively.

Modes for Carrying Out the Invention

[0008] Hereinafter, modes for carrying out the invention will be described with reference to embodiments.

Embodiment

[0009] Embodiment 1 will be described with reference to FIGS. 1 to 5. A generator is a device that obtains electrical energy by the electromagnetic induction action of a coil and a magnet. Electromagnetic induction is a phenomenon in which a current is generated in a conductor by moving the conductor in a magnetic field. There are generators that continuously generate electricity by electromagnetic induction when a magnet in a coil (conductor), such as those used in bicycles, rotates, and those in which the coil rotates in a magnetic field. The rotating shaft is an important element.

[0010] The generator of this embodiment includes a part of the rotating shaft 1 that drives the coil or magnet inside the generator 10 (the generator main body). Furthermore, it includes a pair of bellows pump chambers 21 and 22, a windmill 3 housed in the windmill chamber 100, and a pair of switching point plates 31 and 32 disposed inside the windmill chamber 100 for changing the air flow (wind flow) generated by water pressure. (Refer to FIGS. 1 to 3). In the pair of bellows pump chambers 21 and 22, the lower part of one bellows pump chamber 22 is connected to one upper end part of the windmill chamber 100 via a connecting part 42 such as a pipe, and the other upper end part of the windmill 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 windmill chamber 100, a windmill 3 with a plurality of blades attached around a windmill rotating shaft (not shown) is arranged, and the windmill rotating shaft is connected to the rotating shaft 1 of the generator 10. Therefore, as the windmill 3 rotates, the rotating shaft 1 rotates accordingly, and the generator 10 generates electricity accordingly. (Refer to FIGS. 4 and 5).

[0011] In a generator with such a configuration, the rotating shaft driving part is installed underwater together with the generator. At this time, the slide door 26 of one bellows pump chamber 22 is open, and the slide door 25 of the other bellows pump chamber 21 is closed. Then, water enters one bellows pump chamber 22 from the opening 27 of the open part, compresses air with its water pressure, and generates an air flow. (Refer to FIG. 1). At this time, this air flow (wind flow) tilts the switching point plates 31 and 32 upward, for example, as shown in FIG. 1, so that it flows from right to left under the windmill. By taking such measures, the windmill 3 rotates as shown by the thick arrow in the figure, and therefore, the rotating shaft 1 of the generator connected to the windmill 3 also rotates in the same way. Next, as shown in FIG. 2, the switching point plates 31 and 32 are tilted downward so that the upper side of the windmill 3 flows from left to right. Even in this case, the windmill 3 rotates as shown by the thick arrow in the figure, and ultimately the rotating shaft 1 connected to the windmill 3 also rotates in the same way.

[0012] By correctly matching the opening and closing times of the slide doors 25 and 26 configured in this way with the switching times of the switching point plates 31 and 32, the windmill 3 rotates in a fixed direction, and the rotating shaft 1 connected to the windmill 3 rotates according to the rotation of the windmill 3. Therefore, the hydraulic generator 10 using this windmill 3 functions (generates electricity) effectively. FIG. 3 is a perspective view of a hydraulic generator having a windmill of an embodiment installed in water. The generator 1 is adjacent to the windmill chamber 100, and the windmill chamber 100 is installed between a pair of bellows pump chambers 21 and 22. In the figure, the drainage towers 23 and 24 are configured to be exposed from the water surface 12 and discharge the water pushed out by the water pressure to the outside.
