[0003] [Patent Document 1] JP 2007-82386 A 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 arranged in close proximity to the coil, a rotating shaft fixed to the center of the coil, and a driving means for rotating the rotating shaft, and obtains electrical energy by electromagnetic induction between the coil and the magnet. The rotating shaft attached to the magnet is connected to the driving means, and a current generated by electromagnetic induction between the coil and the magnet rotated by the driving means flows through a conductor connected to the coil to, for example, a storage battery and is stored therein. Conventionally, it is important for such generators to rotate the magnet efficiently. The present invention has been made in view of the above circumstances, and provides a generator having a novel structure that utilizes the force of water (hydraulic force) to generate electricity efficiently underwater. [Means for solving the problem]

[0005] The generator of the present invention is a generator that obtains electrical energy by electromagnetic induction between a coil and a magnet, and is equipped with a rotating shaft that drives the coil or the magnet, and further equipped with a rotating shaft drive unit consisting of a pair of bellows pump chambers and a pair of piston chambers, each of the pair of piston chambers is provided with a piston, and each piston is connected to the rotating shaft by a crankshaft so that when one rises the other falls, the pair of piston chambers are conductive at their lower ends, the lower part of one of the bellows pump chambers is connected to the upper end of the one piston chamber via a pipe or the like, and the lower part of the other bellows pump chamber is connected to the upper end of the other piston chamber via a pipe or the like, and the upper ends of the pair of bellows pump chambers are each provided with a drainage tower and a sliding door, and the sliding door is configured so that when one is open, the other is closed. In a generator having such a configuration, the rotary shaft drive unit is placed underwater together with the generator. At this time, 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, and the water pressure compresses the air, pushing down the piston of one piston chamber and pushing up the piston of the other piston chamber. The piston of the other piston chamber that has been pushed up pushes the air against the upper end of the other bellows pump chamber, discharging it from this chamber into a drain tower. Next, when the sliding door is switched between opening and closing to open the other bellows pump chamber and close the sliding door of one of the bellows pump chambers, water enters the other bellows pump chamber through the opening, and the water pressure compresses the air, pushing down the piston of the other adjacent piston chamber and pushing up the piston of one of the piston chambers. The piston of the one piston chamber that has been pushed up pushes the air against the upper end of the one of the adjacent bellows pump chambers and discharges it into the discharge tower. In this way, by opening and closing the pair of sliding doors, the pair of pistons can be raised and lowered to rotate the rotary shaft. Effect of the Invention

[0006] The generator of the present invention has a rotating shaft drive section with a novel structure in which the rotating shaft is rotated by the force of water (hydraulic force), and generates electricity efficiently. [Brief description of the drawings]

[0008] Hereinafter, the embodiment of the present invention will be described with reference to the examples. EXAMPLES

[0009] A first embodiment will be described with reference to FIGS. A generator is a machine that obtains electrical energy through the electromagnetic induction effect of a coil and 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 generators such as those used on 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, where the rotating shaft is an important element.

[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 consisting of a pair of bellows pump chambers 21, 22 and a pair of piston chambers 31, 32. Pistons 33, 34 are provided in the pair of piston chambers 31, 32, respectively. Each piston 33, 34 is connected to the rotating shaft 1 by crankshafts 35, 36 so that when one piston rises, the other falls. The pair of piston chambers 31, 32 are electrically connected at their lower ends. The lower part of one bellows pump chamber 21 is connected to the upper end of one piston chamber 31 via a connecting part 4 such as a pipe, and the lower part of the other bellows pump chamber 22 is connected to the upper end of the other piston chamber 3 via a connecting part 42 such as a pipe. Drainage towers 23, 24 and electrically operated sliding doors 25, 26 are provided at the upper ends of the pair of bellows pump chambers 21, 22, respectively, and the sliding doors 25 are configured so that when one of the doors is open, the other closes.

[0011] In a generator configured as described above, the rotating shaft drive unit, together with the generator body 10 and the rotating shaft 1, is installed underwater below the water surface 12. At this time, the sliding door 25 of one bellows pump chamber 21 is open, and the sliding door of the other bellows pump chamber is closed. Therefore, water 11 enters one bellows pump chamber 31 through the opening 27, and the water pressure causes the air in the bellows 29 to push down the piston 33 in one piston chamber 31 and push up the piston 34 in the other piston chamber 32. The pushed-up piston 34 in the other piston chamber 32 pushes the air against the upper end of the other bellows pump chamber 22, discharging it from this chamber into the atmosphere via the drain tower 24. Next, when the sliding doors are switched between open and closed, and the sliding door 26 of the other bellows pump chamber 22 is opened and the sliding door 25 of one bellows pump chamber 21 is closed, water 11 enters the other bellows pump chamber 22 from the opening 28, and the water pressure compresses the air in the bellows 30, pushing down the piston 34 of the other adjacent piston chamber 32 and pushing up the piston 33 of one piston chamber 31. The piston 33 of the one piston chamber 31 that has been pushed up pushes up the air to the upper end of the one adjacent bellows pump chamber 21, and the water 11 that entered the chamber from the opening in the previous operation is discharged to the outside from the discharge tower 23 (see FIG. 1).

[0012] Next, in the same manner as when the rotating shaft drive unit is placed underwater together with the generator body 10 and the rotating shaft 1, the slide door 25 of one bellows pump chamber 21 is opened and the slide door 26 of the other bellows pump chamber 22 is closed. As a result, water 11 enters one bellows pump chamber 31 through the opening 27, and the air in the bellows 29 presses down the piston 33 of one piston chamber 31 due to the water pressure, and presses up the piston 34 of the other piston chamber 32. The piston 34 of the other piston chamber 32 that has been pressed up presses up the water to the upper end of the other bellows pump chamber 22, and then flushes it out of this chamber into the atmosphere via the drain tower 24 (see FIG. 2).

[0013] In this way, by repeatedly opening and closing the pair of sliding doors, the pair of pistons are raised and lowered, thereby rotating the rotating shaft and generating electricity. The generator of the present invention has a rotating shaft drive section with a novel structure in which the rotating shaft is rotated by the force of water (hydraulic force), and generates electricity efficiently. FIG. 5 shows another example of this embodiment, where drainage towers 23, 24 are configured to connect to underground drainage pipes 19, 20. [Explanation of symbols]
