Description

[Technical field]

[0001] The present invention relates to the field of hydroelectric power generation technology, and more particularly to a new hydroelectric power generation device. [Background technology]

[0002] Hydroelectric power generation is a production process that converts hydraulic energy into electrical energy using a power generating device. Conventional hydroelectric power plants generally build a dam on a river to raise the head of the water, and then open a drainage channel on the side of the dam to convert potential energy into kinetic energy through the difference in water height to rotate a generator. There are many hidden disasters and dangers, high costs, a huge system, high technical requirements, and difficult to spread widely. In addition, storing water in a dam is very inconvenient for boating. In addition, many rivers have fast currents, so embankments should not be built, and the water in the river flows in vain, and the kinetic energy of the flowing water is not utilized, resulting in a waste of valuable hydroelectric resources.

[0003] Also, a more efficient hydroelectric power generating device using a water hammer pump has been disclosed (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2017-166395 A Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention provides a new type of hydroelectric generating device that addresses shortcomings in the prior art. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention proposes the following technology. The present invention provides a new type of hydroelectric power generation device, including a water collecting vessel, a movable vessel, and a turbine generator. The movable vessel is accommodated inside a water collecting vessel with an open top. The movable vessel includes an upper cylinder, a lower cylinder, and a dome, and the upper and lower cylinders are hollow cylindrical structures. The dome adopts a bottom-up funnel-shaped structure that gradually narrows from the bottom periphery inside the lower cylinder. A water gate mechanism installed at the bottom of the side wall of the upper cylinder controls the opening, closing, and stocking of liquid passing between the water collecting vessel and the movable vessel. As the liquid increases, the movable vessel moves downward when the total gravity of itself and the liquid exceeds the buoyancy. As the liquid decreases, the movable vessel begins to float when the buoyancy it can withstand exceeds the total gravity of itself and the liquid. The turbine generator installed at the narrow mouth of the dome operates by receiving the vortex flowing from below the dome during downward movement. The water intake pipe is connected to an external water intake device.

[0007] Furthermore, the aforementioned water gate mechanism is composed of a water gate, a water gate mouth, a pulley, an ejector rod, a buoy, a connecting member and a hook, the water gate mouth provided on the side wall of the moving container matches the contour of the water gate, the water gate moves with the pulley through the connecting member, the lower part of the connecting member is connected to the tip of the ejector rod, the base of the ejector rod extends from the bottom of the water gate mechanism, and when the moving container shifts down to a certain location and the base of the ejector rod comes into contact with the bottom of the water collecting container, the connecting member is held down, so that the connecting member pulls the water gate from the water gate mouth. An opening groove is installed above the connecting member, a hook is inserted into the aforementioned opening groove, the hook is connected to the buoy, and when the buoy is subjected to a certain buoyancy, the connecting member is pulled from above, so that the sluice is left open, and the liquid contained in the upper cylinder flows from the sluice port into the water collection container, the moving container gradually rises, and the supporting force of the ejector rod is relaxed. When the liquid contained in the upper cylinder has almost completely flowed out, the buoyant force applied to the buoy disappears, and when there is no external force, the sluice slides back into the sluice port and the sluice port closes.

[0008] In addition, the expandable and contractible seal is also provided around the bottom of the aforementioned moving container, and the seal is connected to a hydraulic pipe, which is connected to a hydraulic pump, which controls the expansion or contraction of the seal through the hydraulic pipe.

[0009] In addition, the distance between the water collection container and the movable container is 2-3 cm, and the volume of the movable container exceeds the volume of the water collection container. Effect of the Invention

As the amount of liquid added increases, the total gravity of the movable container 2 and the liquid added exceeds the buoyancy, and the movable container 2 moves downward. As the amount of liquid added decreases, the buoyancy that the movable container 2 can receive exceeds the total gravity of the movable container 2 and the liquid added, and the movable container 2 begins to float. The turbine generator 3 installed at the narrow mouth of the dome 23 operates by receiving the vortex flowing from below the dome 23 while moving downward, and the water intake pipe 7 is connected to an external water intake device.

[0014] In this embodiment, as shown in Figures 1 and 2, the water gate mechanism 6 is located at the bottom of the upper cylinder 21, and the water gate mechanism 6 is composed of a water gate 61, a water gate mouth 62, a pulley 63, an ejector rod 64, a buoy 65, a connecting member 66 and a hook 67, the water gate mouth 62 provided on the side wall of the movable container 2 matches the contour of the water gate 61, the water gate 61 moves along with the pulley 63 through the connecting member 66, the lower part of the connecting member 66 is connected to the tip of the ejector rod 64, the base of the ejector rod 64 extends from the bottom of the water gate mechanism 6, and the connecting member 66 is held down when the movable container 2 shifts down to a certain location and the base of the ejector rod 64 comes into contact with the bottom of the water collection container 1. The connecting member 66 pulls the sluice gate 61 out of the sluice gate mouth 62, an opening groove is installed above the connecting member 66, a hook 67 is accommodated in the aforementioned opening groove, the hook 67 connects to the buoy 65, and when the buoy 65 is subjected to a certain buoyancy, the connecting member 66 is pulled from above, so that the sluice gate 61 is left open and the liquid contained in the upper cylindrical body 21 flows from the sluice gate mouth 62 into the water collection container 1, the moving container 2 gradually rises, the supporting force of the ejector rod 64 is loosened, and when the liquid contained in the upper cylindrical body 21 has almost completely flown out, the buoyancy force received by the buoy 65 disappears, and when there is no external force, the sluice gate 61 slides back into the sluice gate mouth 62, and the sluice gate mouth 62 closes.

[0015] In this embodiment, as shown in FIG. 3, the seal 8 that can be expanded and contracted is connected to the bottom of the moving container 2, and the seal 8 is connected to the hydraulic pipe 4, and the hydraulic pump is connected to the hydraulic pipe 4, and the hydraulic pump controls the expansion or contraction of the seal 8 through the hydraulic pipe 4.

[0016] In this embodiment, the distance between the water collection container 1 and the moving container 2 is 2-3 cm, and the volume of the moving container 2 exceeds the volume of the water collection container 1.

[0017] In this embodiment, the turbine generator 3 utilizes an insulating horizontal generator.

[0018] About the operating principle of the hydroelectric generator according to the present invention (1) A certain amount of liquid is placed in the water collection vessel 1, the movable vessel 2 is placed in the water collection vessel 1 and initially floats on the liquid contained in the water collection vessel 1, and the sluice gate mechanism 6 is closed. (2) After the hydraulic pump extends the seal 8 through the hydraulic pipe 4, and while the suction pipe 7 is sucking out the liquid between the water collection container 1 and the movable container 2, the movable container 2 is in an unstable state, the buoyancy force it receives gradually weakens, and it is only subjected to its own gravity and the friction force between the movable container 2 and the fixed bearing 5. (3) The movable container 2 moves downward due to gravity, and due to the principle of action and reaction, the water below the dome 23 is stored in the side walls of the dome 23 and springs out into the turbine generator 3, pulling and powering the turbine generator 3 to generate electricity. (4) When the moving container 2 moves to the lowest position, the water gate mechanism 6 opens, the liquid in the upper cylinder 21 in the moving container 2 flows back into the water collection container 1, and at the same time the sill contracts, the moving container 2 floats again due to buoyancy, and a cycle is completed on the liquid. When the moving container 2 moves to the lowest position, the water gate mechanism 6 opens, the liquid in the upper cylinder 21 in the moving container 2 flows back into the water collection container 1, and at the same time the seal contracts, and the moving container 2 floats again on the liquid due to buoyancy, thus completing one cycle.
