【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, the compressed air generator utilizing wave force is a cylinder tube vertically held by a cylinder vertical holding bar 9 fixed at a predetermined position of a support column 19 fixed to the seabed B. 10 and a vertically movable body 1 which has a piston 2 slidable with respect to the cylinder tube 10 in the center and vertically moves with the outer peripheral surface 11 of the cylinder tube 10 as a guide. A permanent magnet plate 3 having a plurality of permanent magnets 4a is attached, and a plurality of permanent magnets 4b is provided above the permanent magnet plate 3 so that the plurality of permanent magnets 4a of the permanent magnet plate 3 can be magnetically attracted. The permanent magnet attracting plate 17 is provided.

The cylinder tube 10 has an inlet 12 for sucking air into the cylinder tube 10 and an air outlet 13 for sending compressed air in the cylinder tube 10 to the compressed air storage tank 21. A check valve 14 composed of a valve body 15 and a spring 16 is attached to the intake port 12 and the air supply port 13 so that when the piston 2 is moved upward, only the intake port 12 is opened. It is set so that only the air supply port 13 is opened when the valve moves downward. Further, a suction pipe 25 having a filter 24 for sucking the atmosphere is connected to the suction port 12, and the air supply port 13 is connected to the compressed air storage tank 21 via the air supply pipe 22.

The vertical moving body 1 is composed of a main body 5 made of a cylindrical foam having a piston 2 in the center, steel covering the peripheral surface 6 thereof, and a weight 8 housed in the main body 5, The lower part thereof is composed of a tapered surface 7 whose diameter becomes smaller as it goes downward, and the permanent magnet plate 3 on which a plurality of permanent magnets 4a are arranged is horizontally mounted on the upper part thereof. As shown in FIG. 5, a plurality of permanent magnets 4a are arranged on the permanent magnet plate 3 with their polarities (N pole, S pole) alternately. Further, the permanent magnet attracting plate 17 provided above the vertical moving body 1 is held at a predetermined position of the column 19 by the permanent magnet attracting plate holding bar 18, and is disposed on the permanent magnet attracting plate 17. As shown in FIG. 6, the plurality of permanent magnets 4b are alternately arranged with their polarities reversed so as to be magnetically attracted to the plurality of permanent magnets 4a arranged on the permanent magnet plate 3. ing.

The cylinder vertical holding bar 9 and the permanent magnet attracting plate holding bar 18 are positioned by the positioning pins 20, and can be positioned arbitrarily according to the sea surface S, wave height, and the like. .. Further, the plurality of permanent magnets 4a and 4b are formed of rare earth magnets and have a sufficient magnetic attraction force.

Next, the operation will be described. After the pillar 19 is driven into the seabed B and fixed, the cylinder vertical holding plate 9 and the permanent magnet attracting plate holding bar 17 are fixed at predetermined positions to set the vertical moving body position of the vertical moving body 1. When the sea surface S rises due to the arrival of waves, the vertical moving body 1 obtains buoyancy, so that the vertical moving body 1 moves upward as the sea surface S rises, and as shown in FIG. The permanent magnet plate 3 attached to the upper part and the plurality of permanent magnets 4a and 4b of the permanent magnet attracting plate 17 provided above the permanent magnet plate 3 magnetically attract. At this time, the check valve 14 provided at the suction port 12 of the cylinder tube 10 is opened and the atmosphere is sucked into the cylinder tube 10 (arrow I in the figure). Furthermore, at this time, even if the rise of the sea surface S is smaller than the predetermined amount, the vertical moving body 1 is attracted by the magnetic attraction force of the plurality of permanent magnets 4a, 4b, and the rise of the sea surface S is larger than the predetermined amount. In this case, since the upward movement is limited by the permanent magnet attraction plate 17 provided above the vertical moving body 1, the vertical moving body 1 is always located at a fixed position.

Next, when the sea surface S descends, in the initial stage, as shown in FIG. 3, the permanent magnet plate 3 of the vertical moving body 1 is attracted to the permanent magnet attracting plate 17 above it. The vertical moving body 1 is once held in the upper moving position. Then, when the sea surface S further descends, the buoyancy acting on the vertical moving body 1 decreases, and the force that the vertical moving body 1 attempts to move downward becomes larger than the magnetic attraction force between the plurality of permanent magnets 4a, 4b, The moving body 1 starts downward movement. Then, as the up-and-down moving body 1 moves downward so as to follow the descent of the sea surface S, the air in the cylinder tube 10 is compressed, the check valve 14 of the air supply port 13 of the cylinder tube 10 is opened, and the compressed air is compressed. Air is supplied to the air storage tank 21 (arrow E in the figure). At this time, since the up-and-down moving body 1 is moving downward so as to follow the sea surface S, it moves downward without being affected by the buoyancy due to the sea surface S, and the stroke of the downward movement is set constant as described above. As a result, compressed air can be constantly and stably generated even when the wave height changes every moment, so that compressed air can be efficiently generated. Then, by repeating the above operation, compressed air is stored in the compressed air storage tank 21 and used as the power or auxiliary power of the compressed air using device 23.

Then, the cylinder vertical holding bar 9 and the permanent magnet attracting plate holding bar 18 are moved up and down in accordance with the change of the sea surface S or the wave height due to the tide or the weather, so that the compression is performed under any conditions. Air can be generated, and the pressure of compressed air can be arbitrarily set by changing the weight of the weight 8 housed in the vertical moving body 1. Further, since the lower part of the vertical moving body 1 is composed of the tapered surface 7 having a smaller diameter as it goes downward, the vertical moving body 1 is less susceptible to wave undulations and the like, and can be moved vertically smoothly.

[0016]

[Effect of the device]

 As described in detail above, the present invention has the following effects. That is, according to claim 1, the upper and lower moving bodies that move up and down due to rising and lowering of the sea surface due to waves are attached to the permanent magnet plate, and the permanent magnet attracting plate provided on the upper portion is magnetically attracted. The vertical stroke of the vertical moving body is always kept constant because the vertical moving body is held in the upper moving position by the above, and when the vertical moving body is moved downward, the vertical moving body is not affected by buoyancy, so compressed air at a constant pressure is stabilized. Can be generated. According to the second aspect of the present invention, since the vertical moving body is formed of foam, and the peripheral surface thereof is covered with the steel, sufficient buoyancy can be obtained, and at the same time, a high strength vertical moving body can be obtained. Since the lower part is composed of a tapered surface, it is not easily affected by wave undulations, etc., and it can move up and down smoothly. Furthermore, by accommodating a weight inside the up and down moving body, it can move up and down in a well-balanced manner. The compressed air of arbitrary pressure can be obtained by changing the weight.

According to the third aspect of the present invention, the vertical cylinder holding bar and the permanent magnet attraction plate holding bar can be arbitrarily moved up and down, so that it is possible to flexibly respond to changes in the sea surface and wave height due to tides and weather. Therefore, it is possible to provide a compressed air generating device using wave force that can be used under various conditions. Further, according to the fourth aspect, by using a rare earth magnet having a strong magnetic force as the permanent magnet, the vertical moving body can be reliably held in the upper moving position, and compressed air can be generated more stably.
