Description

[Technical field]

[0001] The present invention relates to a generator having a drive mechanism for driving a rotating shaft of the generator. [Background technology]

[0002] The inventor of the present application has previously proposed a generator in which the rotating shaft of the generator is driven by water pressure (Patent Document 1 below). As shown in FIG. 5, the drive mechanism of this generator includes a pair of bellows pump chambers 221, 231 in which bellows pumps 222, 232 are arranged, a pair of piston chambers 226, 236 in which pistons 227, 237 are arranged, and crankshafts 228, 238 that convert the reciprocating motion of the pistons 227, 237 into the rotational force of a rotating shaft 241 of a generator 240. The generator 240 and the piston chambers 226, 236 are disposed underwater, and the bellows pump chambers 221, 231, too, are submerged except for the tips of the drainage towers 224, 234 which protrude above the water surface 300.

[0003] An electrically operated sliding door 223, 233 is provided at the upper end of the main body of the bellows pump chamber 221, 231, and these sliding doors 223, 233 are controlled so that when one of them is opened, the other is closed. The pair of piston chambers 226, 236 are mutually connected at their lower ends. In addition, the lower part of the bellows pump chamber 221 and the upper part of the piston chamber 226 are connected by a pipe 225 through which air can flow, and similarly, the lower part of the bellows pump chamber 231 and the upper part of the piston chamber 236 are connected by a pipe 235 through which air can flow.

[0004] 5, in this drive mechanism, when the slide door 233 of one bellows pump chamber 231 is closed, the slide door 223 of the other bellows pump chamber 221 is open, so that water enters the bellows pump chamber 221, and the water pressure presses down the bellows pump 222 of the bellows pump chamber 221. As a result, part of the air that had accumulated in the bellows pump 222 is sent through the pipe 225 to the piston chamber 226, and the piston 227 of the piston chamber 226 descends.

[0005] When the piston 227 in the piston chamber 226 descends, the air below the piston 227 flows into the adjacent piston chamber 236 and pushes up the piston 237 in the piston chamber 236. As a result, the air above the piston 237 is sent to the bellows pump chamber 231 through the pipe 235, and the upper end of the bellows pump 232 in the bellows pump chamber 231 is pushed up. Therefore, the water present at the upper end of the bellows pump chamber 231 is discharged from the drain tower 234 into the atmosphere. In this process, the movement of the descending piston 227 in the piston chamber 226 and the ascending piston 237 in the piston chamber 236 causes the crankshafts 228, 238 to rotate, which in turn causes the rotating shaft 241 of the generator 240 to rotate, generating electricity.

[0006] Next, when the sliding door 233 of the bellows pump chamber 231 opens and the sliding door 223 of the bellows pump chamber 221 closes, water enters the bellows pump chamber 231, and the water pressure pushes down the bellows pump 232 in the bellows pump chamber 231, the piston 237 in the piston chamber 236 descends, and the piston 227 in the piston chamber 226 rises, the upper end of the bellows pump 222 in the bellows pump chamber 221 is pushed up, and the water present at the upper end of the bellows pump chamber 221 is discharged into the atmosphere from the drain tower 224. During this process, the crankshafts 238, 228 rotate in accordance with the movement of the descending piston 237 in the piston chamber 236 and the ascending piston 227 in the piston chamber 226, and the rotating shaft 241 of the generator 240 continues to rotate in the same direction, thereby continuously generating electricity.

[0007] [Patent Document 1] Patent No. 7627408 (issued February 6, 2025) Summary of the Invention [Problem to be solved by the invention]

[0008] However, in the configuration of Figure 1, because the generator 240 operates underwater, it is difficult to safely extract the generated electricity, and maintenance work on the generator 240 is also difficult, etc., which hinders the construction of a large-scale power generation system. The present invention is devised to solve these problems, and has an object to provide a generator that can be used to build a large-scale power generation system. [Means for solving the problem]

[0009] The present invention provides a generator having a drive mechanism for driving a rotating shaft of the generator, This drive mechanism comprises a pair of bellows pump chambers in which a bellows pump is disposed, a pair of piston chambers in which pistons that are linked to the expansion and contraction of the bellows pump are disposed, and a crankshaft that converts the reciprocating motion of the pistons into rotational force of the rotating shaft of the generator, and the pair of bellows pump chambers are disposed below the water surface, and the pair of piston chambers, the crankshaft and the generator are disposed above the water surface. Each of the pair of bellows pump chambers has a sliding door that opens and closes the water inflow path to the bellows pump chamber, and a drain tower that serves as a drain path for water from within the bellows pump chamber when the sliding door is closed, and each of the sliding doors is controlled so that water flows alternately into the pair of bellows pump chambers. In addition, a pipe through which air flows is installed between the bellows pump chamber and the piston chamber, and as the bellows pump or the piston moves, air moves between the bellows pump chamber and the piston chamber through the pipe. In addition, a communication passage is provided between the pair of piston chambers, through which air compressed by the movement of the piston in one of the piston chambers flows into the other piston chamber.

[0010] In this configuration, the generator is positioned above the water surface together with a pair of piston chambers and the crankshaft, making it easy to draw out the electricity generated by the generator and also making it easy to perform maintenance work on the generator.

[0011] In addition, in the present invention, two buildings housing the bellows pump chambers are installed underwater at a distance from each other on foundations at the bottom of the water, a tower-like structure is installed on the roof of each of the buildings, and a building housing the pair of piston chambers, the crankshaft and the generator is installed so as to straddle the two ends of the structures protruding above the water surface, and the pipes and the drainage pipe protruding from each of the buildings installed underwater are connected to each other. tower and are arranged inside the structure of the tower structure.

[0012] This configuration allows the piston chamber, crankshaft and generator to be stably mounted above the water surface. Effect of the Invention

[0013] The generator of the present invention allows easy maintenance and enables the construction of a large-scale power generation system. [Brief description of the drawings]

[Figure 4] A diagram showing a bellows pump chamber installed underwater, a tower-like structure constructed on top of it, and a piston chamber installed at the tip of the structure above the water. [Diagram 5] FIG. 1 is a cross-sectional view showing a generator and its drive mechanism disclosed in Patent Document 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described.

[0016] As shown in FIG. 1, the driving mechanism of the generator of the present invention has a bellows pump chamber 102 equipped with a bellows pump 101, a bellows pump chamber 112 equipped with a bellows pump 111, a piston chamber 122 equipped with a piston 121, a piston chamber 132 equipped with a piston 131, and crankshafts 123, 133 that convert the reciprocating motion of the pistons 121, 131 into rotational force of a rotating shaft 142 of a generator 141.

[0017] Of these, the bellows pump chambers 102, 112 are disposed underwater, and the piston chambers 122, 132 and the crankshafts 123, 133, together with the generator 141, are disposed above water.

[0018] The bellows pump chamber 102 is provided with an electric sliding door 103 that opens and closes the inflow path of water into the pump chamber, and the bellows pump chamber 112 is provided with an electric sliding door 113 that opens and closes the inflow path of water into the pump chamber. The sliding doors 103 and 113 are controlled so that they alternate between "opening" and "closing" the inflow passages, and when one of them is "open," the other is "closed."

[0019] In addition, a pipe 104 through which air flows is provided between the bellows pump chamber 102 and the piston chamber 122, and similarly, a pipe 114 through which air flows is provided between the bellows pump chamber 112 and the piston chamber 132. The pipe 104 connects the lower end of the bellows pump chamber 102 to the upper end of the piston chamber 122 , and the pipe 114 connects the lower end of the bellows pump chamber 112 to the upper end of the piston chamber 132 .

[0020] Furthermore, the lower portion of the piston chamber 122 is in electrical communication with the lower portion of the piston chamber 132 via a conductive passage 150 .

[0021] In addition, the bellows pump chamber 102 has a drain tower 105 which serves as a drainage path for water in the bellows pump chamber 102 when the sliding door 103 is closed, and the bellows pump chamber 112 has a drain tower 115 which serves as a drainage path for water in the bellows pump chamber 112 when the sliding door 113 is closed. The drainage tower 105 extends upward from the upper end of the bellows pump chamber 102, and the tip of the drainage tower 105 is exposed above the water surface 300. Similarly, the drainage tower 115 extends upward from the upper end of the bellows pump chamber 112, and the tip of the drainage tower 115 is exposed above the water surface 300. Therefore, the water discharged from the drain towers 105, 115 mixes with the water surrounding the bellows pump chambers 102, 112 after being discharged into the air.

[0022] 1, when the sliding door 113 of the bellows pump chamber 112 is closed and the sliding door 103 of the bellows pump chamber 102 is opened, the water around the bellows pump chamber 102 flows into the bellows pump chamber 102. Therefore, the bellows pump 101 is compressed by the water pressure of the flowing water, and the air in the bellows pump 101 is sent to the piston chamber 122 through the pipe 104, and as a result, the piston 121 in the piston chamber 122 descends.

[0023] When the piston 121 descends, the air below the piston 121 is pushed out into the piston chamber 132 through the conducting passage 150 between the piston 121 and the piston chamber 132, causing the piston 131 to rise. When the piston 131 rises, the air above the piston 131 is sent to the bellows pump chamber 112 through the pipe 114, and the bellows pump 111 in the bellows pump chamber 112 expands. Therefore, the water inside the bellows pump chamber 112 with the sliding door 113 closed is discharged into the air through the drain tower 115.

[0024] During this process, the crankshafts 123, 133 rotate with the movement of the piston 121 descending in the piston chamber 122 and the piston 131 ascending in the piston chamber 132, thereby rotating the rotating shaft 142 of the generator 141, and generating electricity in the generator 141.

[0025] FIG. 3 shows the relationship between the generator 141 and the pistons 121, 131 and crankshafts 123, 133 that drive the generator 141.

[0026] On the other hand, as shown in FIG. 2, when the sliding door 113 of the bellows pump chamber 112 opens and the sliding door 103 of the bellows pump chamber 102 closes, the operations reverse to those in FIG. 1 are performed in the bellows pump chambers 121, 122 and the piston chambers 132, 133. That is, the water around the bellows pump chamber 112 flows into the bellows pump chamber 112, compressing the bellows pump 111, and the air in the bellows pump 111 is sent to the piston chamber 132, causing the piston 131 to descend and the piston 121 to ascend. Therefore, the air above the piston 121 is sent to the bellows pump chamber 102, causing the bellows pump 101 to expand, and the water inside the bellows pump chamber 102 with the sliding door 103 closed is discharged from the drain tower 105 into the air.

[0027] During this process, with the movement of the descending piston 131 and the ascending piston 121, the crankshafts 123, 133 rotate in the same direction as in Figure 1, thereby causing the rotating shaft 142 of the generator 141 to rotate in the same direction as in Figure 1, and power generation by the generator 141 continues.

[0028] FIG. 4 illustrates an example of an installation form of the generator and the drive mechanism according to the present invention. Here, a rectangular parallelepiped first building 151 that houses the bellows pump room 102 and a rectangular parallelepiped second building 152 that houses the bellows pump room 112 are placed at a distance underwater on foundations at the bottom of the water, and tower-structured structures 161, 162 are installed on the roofs of the first building 151 and the second building 152, respectively.

[0029] A third building 153 is constructed so as to straddle the two tips of these structures 161, 162 protruding above the water surface, and the piston chambers 122, 132, crankshafts 123, 133 and generator 141 are housed inside this third building 153.

[0030] In addition, the pipe 104 connecting the bellows pump room 102 and the piston room 122, and the drainage tower 105 extending from the bellows pump room 102 to above the water surface are arranged inside a tower-structured structure 161 installed on the roof of the first building 151, and the pipe 114 connecting the bellows pump room 112 and the piston room 132, and the drainage tower 115 extending from the bellows pump room 112 to above the water surface are arranged inside a tower-structured structure 162 installed on the roof of the second building 152.

[0031] This structure makes it possible to stabilize the piston chamber, the crankshaft, and the generator, which are arranged above the water surface. [Industrial Applicability]

[0032] The generator of the present invention is capable of generating electricity by utilizing changes in water pressure, and can be widely used as a clean means of generating electricity. [Explanation of symbols]
