Description

Technical Field

[0001] The present invention relates to the technical field of new energy power generation, in particular to an independent circulation power generation system connecting gravity and buoyancy. Background Art

[0002] While people are dedicated to the research, development, and utilization of various green, pollution-free power generation devices, the technology for converting buoyancy and gravity into mechanical energy for power generation has yet to effectively connect the two; both are only suitable for energy storage, not independent power generation.

[0003] Chinese patent publication number CN117803517A proposes a compact gravity buoyancy power generation device, including a water tank, a pair of main sprockets and slave sprockets arranged in a vertical direction inside the water tank, a chain meshingly connected between the main sprockets and the slave sprockets, a float bucket arranged on the chain, and an opening provided in the float bucket along the direction of chain rotation. The main sprocket is installed on a hollow main shaft, the front end of the main shaft extends from the water tank and is installed with a connecting gear and a starting gear, the connecting gear is connected to the gearbox, the gearbox is connected to the generator, the rear end of the main shaft is connected to an air intake assembly arranged outside the water tank, a fixed valve is installed in the main shaft, the front end of the fixed valve is closed and the rear end is open, a fan-shaped opening is provided on the side wall of the fixed valve, and a number of air supply pipes are arranged on the main shaft corresponding to the installation position of the fixed valve, and the end of the air supply pipe has an air supply port opening facing the float bucket. It can be seen that delivering air under water with water pressure requires a lot of energy to force the gas in, and using bubbles to drive the rotor for buoyancy power generation is an inefficient method. It is difficult to promote and utilize it due to the low input-output ratio. Summary of the Invention

[0017] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0018] like Figures 1-4 As shown, an independent circulation power generation system connecting gravity and buoyancy is suitable for scenes with height differences or closed containers such as oceans, lakes, ship hulls, any open space above or below the ground, hydropower station dams, abandoned mines, etc.

[0019] The independent circulation power generation system includes a device body 1 and several buoyancy balls 25. The left and right sides of the device body 1 are respectively provided with a vertically arranged buoyancy upward channel and a gravity downward channel. The buoyancy ball 25 can move vertically in the buoyancy upward channel and the gravity downward channel, and the buoyancy upward channel and the gravity downward channel are gap-matched with the buoyancy ball 25, allowing only one buoyancy ball 25 to pass, and two buoyancy balls 25 are not allowed to pass in parallel.

[0020] An upper connecting channel connecting the upper end of the buoyancy upward channel and the upper end of the gravity downward channel is opened on the upper side of the interior of the device main body 1, and a lower connecting channel connecting the lower end of the buoyancy upward channel and the lower end of the gravity downward channel is opened on the lower side of the interior of the device main body 1. The buoyancy upward channel includes an outer cabin and a pressure-type self-opening transition cabin located on the lower side of the outer cabin. The lower connecting channel, the pressure-type self-opening transition cabin, the outer cabin and the upper connecting channel are connected in sequence.

[0021] The buoyancy ball 25 can move inside the lower communication channel, the upper communication channel, the buoyancy upward channel and the gravity downward channel; The interior of the buoyancy upward channel is filled with a first liquid, the liquid level of the first liquid being the high liquid level line 17. The interior of the lower communicating channel and the lower portion of the gravity downward channel form a lower water storage area, and the interior of the lower water storage area is filled with a second liquid, the liquid level of the second liquid being the low liquid level line 7. The provision of a pressure-type self-opening transition tank allows the water pressures of the first liquid and the second liquid to be different. Here, the first liquid and the second liquid are preferably water.

[0022] The inner wall of the lower side of the upper connecting channel is a gravity slope 21, which slopes downward from left to right. When the buoyant ball 25 falls on the upper side of the gravity slope 21, the buoyant ball 25 will fall into the interior of the gravity downward channel along the gravity slope 21 under the action of gravity, and then fall inside the gravity downward channel. The inner wall on the upper side of the lower connecting channel is a buoyancy slope 8, which tilts downward from left to right. When the buoyancy ball 25 is located on the lower side of the buoyancy slope 8, the buoyancy ball 25 will rise along the buoyancy slope 8 to the inside of the pressure-type self-opening transition cabin under the action of buoyancy.

[0023] like Figure 1 As shown, the movement of the buoyancy ball 25 in the hollow cavity is explained here. When the buoyancy ball 25 falls on the upper side of the gravity slope 21, multiple buoyancy balls 25 fall into the interior of the gravity downward channel in turn, and then descend in the gravity downward channel until they fall into the interior of the second liquid. Since multiple buoyancy balls 25 fall in turn, when the total weight of multiple buoyancy balls 25 is greater than the buoyancy force applied to the buoyancy ball 25 by the second liquid, the buoyancy ball 25 will fall into the bottom of the hollow cavity. When the height of the buoyancy ball 25 is lower than the buoyancy slope 8, it will move to the pressure-type self-opening transition cabin under the action of buoyancy. At this time, the buoyancy ball 25 is Under the action of buoyancy, pressure is applied to the pressure-type self-opening transition cabin, and the pressure-type self-opening transition cabin is pushed open, so that the buoyancy ball 25 can enter the buoyancy upward channel under the action of buoyancy, and ascend along the buoyancy upward channel until the buoyancy ball 25 rises to the top of the buoyancy upward channel, and then the buoyancy ball 25 located at the top of the buoyancy upward channel is pushed into the upper side of the gravity slope 21 by the remaining buoyancy balls 25 below it. This is repeated to complete the downward movement of the buoyancy ball 25 under the action of gravity and the upward movement under the action of buoyancy, thereby driving the buoyancy ball 25 to perform a cyclic up and down movement alternately by buoyancy and gravity.

[0024] Specifically, the upper end of the outer side of the device body 1 is fixedly connected with a water inlet 18 for taking water into the buoyancy upward channel inside the device body 1, and the lower end of the outer side of the device body 1 is fixedly connected with a water outlet 6 for discharging water.

[0025] At the same time, a mesh isolation plate 5 is fixedly connected to the inner wall of the side of the device body 1 close to the water outlet 6. Through the cooperation of the mesh isolation plate 5 and the inner wall of the gravity downward channel, the buoyancy ball 25 can be guided, and the buoyancy ball 25 coming down from the gravity unit can be effectively stacked vertically to form pressure, and gravity can be effectively used to press the ball below into the bottom of the water to do work along the buoyancy slope 8.

[0026] The pressure-type self-opening transition chamber is one of the core technologies of this technical solution. Figure 1 As shown, the pressure-type self-opening transition cabin includes an A-cabin door 9, a first B-cabin door 11, and a second B-cabin door 13 hinged inside the buoyancy upchannel. The A-cabin door 9, the first B-cabin door 11, and the second B-cabin door 13 are arranged in order from bottom to top. Under the action of the dead weight of the A-cabin door 9, the first B-cabin door 11, and the second B-cabin door 13 and the pressure of the first liquid, the A-cabin door 9, the first B-cabin door 11, and the second B-cabin door 13 are normally closed valves. A water pressure differential balancing valve 14 is fixedly connected to the second B-cabin door 13. The water pressure differential balancing valve 14 can automatically open when the pressure reaches a set value. The space between the A-cabin door 9 and the first B-cabin door 11 is the A-cabin chamber 10, and the space between the first B-cabin door 11 and the second B-cabin door 13 is the B-cabin chamber 12. When the buoyancy ball 25 moves to the bottom of the A cabin door 9, the buoyancy ball 25 pushes open the A cabin door 9 and enters the A cabin chamber 10 under the action of buoyancy. The A cabin door 9 automatically closes. After closing, the buoyancy ball 25 continues to float up, pushes open the first B cabin door 11, and enters the B cabin chamber 12. The first B cabin door 11 is closed. After closing, the buoyancy ball 25 continues to float up, pushes open the water pressure difference balancing valve 14, so that the water pressure in the outer cabin is balanced with the water pressure in the B cabin chamber 12. The first B cabin door 11 has been closed, and the first liquid in the outer cabin will not flow out after entering the B cabin chamber 12. At this time, the buoyancy ball 25 pushes open the second B cabin door 13 under the action of buoyancy and enters the outer cabin to do work.

[0027] like Figure 2As shown, a structure of the water pressure differential balancing valve 14 is disclosed herein. The water pressure differential balancing valve 14 includes a slide rod 35 slidably connected to the second B hatch 13. The second B hatch 13 is provided with a plurality of water outlet holes 26 at positions around the slide rod 35. The upper end of the slide rod 35 is fixedly connected to an upper pressure plate 27. The lower side of the upper pressure plate 27 is fixedly connected to a sealing ring 28. The lower end of the slide rod 35 is fixedly connected to a top plate 29. The outer side of the slide rod 35 is sleeved with a return spring 30 located between the second B hatch 13 and the top plate 29. At this time, when the buoyancy ball 25 pushes the top plate 29 upward under the action of buoyancy, When it is lifted up, the upper pressure plate 27 rises and the water outlet 26 is no longer sealed. At this time, the first liquid inside the outer cabin forms a downward water pressure 31 to press downward, and the downward moving first liquid forms flowing water 32 which enters the interior of the B cabin chamber 12 through the water outlet 26 until the water pressure inside the B cabin chamber 12 and the outer cabin is balanced. The buoyancy ball 25 can be reset under the elasticity of the return spring 30, automatically closing the water pressure difference balancing valve 14, and then the upward water pressure 33 applies an upward force to the buoyancy ball 25, so that the second B cabin door 13 can be pushed open, so that the buoyancy ball 25 inside the B cabin chamber 12 enters the interior of the outer cabin.

[0028] like Figure 1 As shown, another core of this technical solution is that the independent cycle power generation system also includes a generator 23, a buoyancy recovery mechanism and a gravity recovery mechanism; The generator 23 can be fixedly connected to the outside of the device body 1. Due to the different installation positions of the system, the generator 23 can be located at the upper, middle and lower parts of the system; if the system is installed in an underground shaft, the generator 23 is placed at the upper part; if the system is installed on the side of a building, the generator 23 is placed in the middle part; if it is installed on the ground, the generator 23 is placed at the lower part.

[0029] The generator 23 is electrically connected to a power output line 24 , and both the buoyancy recovery mechanism and the gravity recovery mechanism are transmission-connected to the generator 23 . The kinetic energy recovered by the buoyancy recovery mechanism and the gravity recovery mechanism is converted into electrical energy by the generator 23 and the electrical energy is output through the power output line 24 .

[0030] The buoyancy recovery mechanism is installed inside the buoyancy upward channel. When the buoyancy ball 25 moves inside the buoyancy upward channel, it can be transmission-connected with the buoyancy recovery mechanism, so that the buoyancy recovery mechanism can recover the buoyancy of the buoyancy ball 25 when it floats upward.

[0031] like Figure 1As shown, the buoyancy recovery mechanism includes a plurality of second rotating rods rotatably connected to the inside of the buoyancy upward channel, the plurality of second rotating rods are arranged vertically, and the circumferential side of the second rotating rod is equipped with a plurality of buoyancy plates 20. The buoyancy plates 20 are preferably L-shaped structures, so that the buoyancy balls 25 can better exert force on the buoyancy plates 20. When the buoyancy balls 25 contact the buoyancy plates 20, an upward thrust can be exerted on the buoyancy plates 20, thereby driving the second rotating rods to rotate through the buoyancy plates 20. The end of the second rotating rod located on the uppermost side is fixedly connected to the second upper gear 19, and the second upper gear 19 is transmission-connected to the generator 23. The remaining second rotating rod ends are fixedly connected to the second lower gear 15. The second upper gear 19 and the outer sides of the plurality of second lower gears 15 are transmission-connected with the second chain 16. At this time, when one of the second rotating rods rotates, the second upper gear 19 can be driven to rotate through the second chain 16.

[0032] Another structure of the buoyancy recovery mechanism is disclosed herein. The buoyancy recovery mechanism includes a second lower gear 15 and a second upper gear 19 that are rotatably connected inside the buoyancy upward channel. The second upper gear 19 is transmission-connected to the generator 23. The second upper gear 19 is located on the upper side of the second lower gear 15. The outer sides of the second lower gear 15 and the second upper gear 19 are transmission-connected with a second chain 16. A plurality of buoyancy plates 20 are assembled on the outer side of the second chain 16. The assembly method of the buoyancy plates 20 can be fixed connection or hinged connection. When the buoyancy ball 25 floats up, the buoyancy plates 20 will be pushed, so that the buoyancy plates 20 drive the second chain 16 to move on the outer sides of the second lower gear 15 and the second upper gear 19, thereby driving the remaining buoyancy plates 20 to move together.

[0033] The gravity recovery mechanism is installed inside the gravity downward channel. When the buoyancy ball 25 moves inside the gravity downward channel, it can be connected to the gravity recovery mechanism in a transmission manner, so that the gravity recovery mechanism can recover the gravity of the buoyancy ball 25 when it falls.

[0034] like Figure 1 As shown, the gravity recovery mechanism includes a plurality of first rotating rods rotatably connected to the inside of the gravity downward channel, and the plurality of first rotating rods are arranged vertically. The peripheral side of the first rotating rod is equipped with a plurality of gravity support plates 34. The material of the gravity support plates 34 is preferably stainless steel or plastic, and has a long service life in water. The gravity support plates 34 are preferably L-shaped structures, so that the buoyancy ball 25 can better exert force on the gravity support plates 34. When the buoyancy ball 25 contacts the gravity support plates 34, a downward thrust can be exerted on the gravity support plates 34, thereby driving the first rotating rod to rotate through the gravity support plates 34. The end of the first rotating rod located on the uppermost side is fixedly connected to the first upper gear 2, and the first upper gear 2 is transmission-connected to the generator 23. The remaining first rotating rod ends are fixedly connected to the first lower gear 4. The outer sides of the first upper gear 2 and the plurality of first lower gears 4 are transmission-connected with the first chain 3. At this time, when one of the first rotating rods rotates, the second upper gear 19 can be driven to rotate through the first chain 3.

[0035] Different from the buoyancy recovery mechanism, the first rotating rod can be directly rotatably connected inside the gravity downward channel, or a mounting groove can be opened on the side wall of the gravity downward channel close to the buoyancy upward channel, and the first rotating rod is rotatably connected inside the mounting groove.

[0036] Another structure of the gravity recovery mechanism is disclosed here. The gravity recovery mechanism includes a first upper gear 2 and a first lower gear 4 that are rotatably connected inside the gravity downward channel. The first upper gear 2 is located on the upper side of the first lower gear 4. The first upper gear 2 is transmission-connected to the generator 23. The outer sides of the first upper gear 2 and the first lower gear 4 are transmission-connected with a first chain 3. The outer side of the first chain 3 is fixedly connected with a plurality of gravity support plates 34. The gravity support plate 34 is preferably an L-shaped structure. When the buoyancy ball 25 floats up, the gravity support plate 34 will be pushed, so that the gravity support plate 34 drives the first chain 3 to move on the outside of the first upper gear 2 and the first lower gear 4, thereby driving the remaining gravity support plates 34 to move together.

[0037] Specifically, such as Figure 1 As shown, the first upper gear 2, the second upper gear 19 and the generator 23 are connected by a rotating chain 22, so that the buoyancy recovery mechanism, the gravity recovery mechanism and the generator 23 can be operated synchronously.

[0038] At this time, initially, the buoyancy ball 25 is placed on the upper side of the gravity slope 21, so that the buoyancy ball 25 falls and drives the gravity support plate 34 to rotate clockwise. When the gravity support plate 34 rotates, the buoyancy plate 20 can be driven to rotate clockwise through the turntable chain 22 and the second upper gear 19. Since multiple buoyancy balls 25 move continuously in sequence inside the device body 1, the buoyancy plate 20 can be driven to move continuously clockwise. By moving the buoyancy ball 25 located at the bottom of the buoyancy recovery mechanism, the buoyancy ball 25 can be located between the second rotating rod and the inner wall of the buoyancy upward channel away from the gravity downward channel.

[0039] like Figure 3 As shown, the structure of the buoyancy ball 25 is disclosed herein. The buoyancy ball 25 comprises a sealed hollow shell filled with at least one of water, air, and an environmentally friendly load to adjust buoyancy and gravity balance. The water-to-air ratio is preferably 1:1, or an environmentally friendly load of equivalent weight is loaded. The buoyancy ball 25 has adjustable gravity and buoyancy, preferably ranging from 10% to 90% of the A compartment. If the buoyancy ball 25 is moving too fast, more water is added to weaken its buoyancy. If the buoyancy ball 25 is moving too slowly, water is removed and air is added to strengthen its buoyancy.

[0040] The materials of environmentally friendly loads can be waste batteries, construction waste, etc., which can be recycled.

[0041] The buoyancy slope 8 and the gravity slope 21 can be a fixed slope surface. The buoyancy slope 8 and the gravity slope 21 are directly fixedly connected to the device body 1. The slope of the buoyancy slope 8 and the gravity slope 21 is preferably 7°.

[0042] Furthermore, the gradients of the buoyancy slope 8 and the gravity slope 21 can be set according to user needs. When a large amount of power generation is required, the gradient can be increased, and vice versa.

[0043] At the same time, the buoyancy slope 8 and the gravity slope 21 can also be an adjustable structure, such as Figure 4 As shown, one of the adjustable structures is disclosed herein. Two electric telescopic rods 36 are fixedly connected to the device body 1. One of the electric telescopic rods 36 is hinged to the buoyancy slope 8 or the gravity slope 21. A slider 38 is also slidably connected to the buoyancy slope 8 and the gravity slope 21. The slider 38 is hinged to the piston rod of the other electric telescopic rod 36. At this time, by activating the two electric telescopic rods 36 respectively, the slope of the buoyancy slope 8 or the gravity slope 21 can be adjusted. A flexible telescopic isolation piece 37 is fixedly connected between the buoyancy slope 8 and the device body 1, and between the gravity slope 21 and the device body 1. After the buoyancy slope 8 or the gravity slope 21 moves, the gap between the buoyancy slope 8 or the gravity slope 21 and the device body 1 is filled by the flexible telescopic isolation piece 37.

[0044] The working principle of the present invention is: When injecting water or salt water from the water inlet 18, all doors are opened in advance. When the injected water reaches the low liquid level line 7, all doors are closed until the injected water reaches the high liquid level line 17. The buoyancy ball 25 enters the buoyancy power generation cycle after passing through the buoyancy slope 8 and entering the A compartment chamber 10 and the B compartment chamber 12; After the buoyancy ball 25 floats to the top, it enters the gravity support plate 34 in the gravity power generation cycle through the gravity slope 21 and moves downward. The first chain 3 pulls the generator 23 to do work. When it approaches the bottom, the first lower gear 4 rotates the gravity support plate 34 to push the buoyancy ball 25, squeezes the buoyancy ball 25 below, and makes it pass through the mesh isolation plate 5 and enter the buoyancy slope 8 on the bottom of the water, and then floats to the A cabin door 9, pushes open the A cabin door 9 to enter the A cabin chamber 10, and the A cabin door 9 automatically closes. The buoyancy ball 25 continues to float up and pushes open the first lower gear 4. Entering the B-compartment compartment 12, the first B-compartment door 11 closes, and the buoyant ball 25 floats upward, opening the water pressure differential equalization valve 14 to equalize the pressure of the outer compartment water with that of the B-compartment compartment 12. The second B-compartment door 13 then opens, allowing access to the outer compartment. This pushes the buoyant plate 20 upward, initiating the buoyancy power generation cycle. When the buoyant ball 25 floats above the high liquid level line 17, it loses buoyancy and, with the help of the buoyant plate 20, propels it upward onto the gravity slope 21, continuing the gravity power generation cycle. The combined pull of the buoyancy unit and the gravity unit drives the generator 23 through the runner chain 22, generating electricity. This electricity is then output via the power output line 24, and the entire power generation process is silent.

[0045] In summary, this technical solution utilizes a hydraulic pressure balance method to connect the buoyancy of the buoyant sphere 25 half from gravity power generation and half from buoyancy power generation, forming an alternating up-and-down cycle power generation system, achieving continuous and uninterrupted power generation with high power generation efficiency. The system boasts a compact structure and stable operation, making it suitable for green energy deployment in any open space, water body, or enclosed space. This power generation method offers high flexibility and fast response, making it particularly suitable for remote areas without access to the national power grid.

[0046] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
