Description

[Technical Field]

[0001] This invention relates to a water circulation and buoyancy ball power generation system, and also to a water circulation and buoyancy ball power generation method. [Background Technology]

[0002] In daily life, water pumps are often used to pump water through pipelines to higher elevations for purposes such as water supply for high-rise buildings, water cooling systems for large equipment, and cleaning of the outer surfaces of photovoltaic units. For example, the column-type photovoltaic units in the energy conversion device and its constituent autonomous energy equipment (publication number CN221177656U) require regular cleaning of their outer surfaces. However, during the water transport process, the flow of water from lower to higher elevations and vice versa is not effectively utilized.

[0003] This invention was made based on the above circumstances. [Summary of the Invention]

[0004] The technical problem to be solved by the present invention is to provide a water circulation and buoyancy ball power generation system with a simple structure. It can use water pumped to a high place to simultaneously transport buoyancy balls to a high place and then separate the water flow and buoyancy balls. The water falling from the high place to the low place and the buoyancy balls are used to generate electricity separately, so as to recover energy.

[0005] To solve the above-mentioned technical problems, the present invention provides a water circulation and buoyancy ball power generation system, comprising a circulation pipeline for circulating water flow, the circulation pipeline including a main pipe for water flow from a lower to a higher position, a plurality of buoyancy balls that can move upward with the water flow inside the main pipe, a bypass channel connected to the main pipe for the buoyancy balls moving upward inside the main pipe to enter and fall, a water intake channel connected to the main pipe for guiding water flowing out of the main pipe to a lower position, a water intake channel being installed on the water intake channel, a rotating component that can be driven to rotate by the falling buoyancy balls being installed on the bypass channel, a generator being connected to the rotating component, a water pump installed on the circulation pipeline to transport water flow into the main pipe, and the circulation pipeline further including a return pipe for returning water flow from the water intake channel to the water pump.

[0006] In the water circulation and buoyancy ball power generation system described above, the bypass channel includes a bypass pipe located below the last rotating component. The bypass pipe is equipped with a first valve and a second valve that can close the bypass pipe. The first valve and the second valve are one-way valves that can be pushed open downwards by a falling buoyancy ball. The first valve and the second valve can automatically close after the buoyancy ball passes through. The bottom end of the bypass pipe is connected to the main pipe. The second valve is located at the connection between the bypass pipe and the main pipe. The first valve and the second valve are spaced apart so that two or more buoyancy balls can be stacked between the first valve and the second valve to push open the second valve and allow the buoyancy ball to enter the main pipe.

[0007] In the water circulation and buoyancy ball power generation system described above, the bypass pipe located between the first valve and the second valve is inclined, and the bypass pipe near the second valve bends in the direction of water flow.

[0008] In the water circulation and buoyancy ball power generation system described above, an inlet channel is provided between the main pipe and the water intake channel to allow water from the main pipe to flow into the water intake channel.

[0009] As described above, in a water circulation and buoyancy ball power generation system, the water inlet channel includes an inlet located at the upper end of the water intake channel, a drain pipe is provided between the main pipe and the water intake channel for water to flow from the main pipe into the water intake channel, the upper end of the bypass channel is higher than the drain pipe and the inlet of the water intake channel, the inlet is smaller than the diameter of the buoyancy ball, and the diameter of the drain pipe is smaller than the diameter of the buoyancy ball.

[0010] In the water circulation and buoyancy ball power generation system described above, a plurality of drain pipes are arranged vertically and protrude from the main pipe. The length of the drain pipes protruding from the bottom to the top within the main pipe increases from short to long so as to guide the upward-moving buoyancy ball to one side of the bypass channel.

[0011] In the water circulation and buoyancy ball power generation system described above, the total water flow area of ​​the water inlet channel is greater than the cross-sectional area of ​​the main pipe.

[0012] As described above, a water circulation and buoyancy ball power generation system consists of multiple sets of systems connected in parallel, including main pipes, bypass channels, water intake channels, and return pipes. The water pump is equipped with a main pipe that supplies water to the multiple sets of main pipes, and the water pump is equipped with a main return pipe that collects and returns the water flow from the multiple sets of return pipes.

[0013] As described above, in a water circulation and buoyancy ball power generation system, the hydroelectric generator includes a main shaft and a rotatable blade assembly mounted on the main shaft. Generator sets are connected to both the left and right sides of the blade assembly on the main shaft, and the blade assembly is driven to rotate by the water flow in the water intake channel.

[0014] In the water circulation and buoyancy ball power generation system described above, the rotating component is installed in the bypass channel via a main shaft. Generators are connected to both the left and right sides of the rotating component on the main shaft. The rotating component includes rotating blades, and several rotating blades are arranged circumferentially around the main shaft. The rotating blades are provided with grooves for falling buoyancy balls to enter and drive the rotating blades to rotate.

[0015] As described above, in a water circulation and buoyancy ball power generation system, the water pump includes a main shaft and an impeller mounted on the main shaft that can rotate. The main shaft is driven to rotate by a power source, which in turn drives the impeller to rotate. Generators are connected to both the left and right sides of the impeller on the main shaft.

[0016] Another technical problem to be solved by the present invention is to provide a water circulation and buoyancy ball power generation method with a simple structure. Water is pumped to a high place and buoyancy balls are simultaneously transported to a high place. The water flow and buoyancy balls are then separated. Power is generated by the water falling from the high place to the low place and the buoyancy balls, respectively, thus recovering energy.

[0017] To solve the above-mentioned technical problems, the present invention provides a water circulation and buoyancy ball power generation method, comprising the water circulation and buoyancy ball power generation system described above. Water is pumped through a main pipe to a higher location. The water flow in the main pipe pushes a buoyancy ball upwards, raising it to a higher position. After the water reaches the upper end of the main pipe, the buoyancy ball is sent to a bypass pipe. Simultaneously, water flows out of the main pipe into a water intake channel, which guides the water from a higher location to a lower location. During this downward flow, the water drives a hydroelectric generator to generate electricity. After treatment, the water flows back to the water tank or pump through the return pipe so that the pump can continue to pump water to higher places. Meanwhile, the buoyancy ball falls from top to bottom in the bypass pipe and hits the rotating component during its fall, causing the rotating component to rotate. The rotating component drives the generator to generate electricity. After rotating at a certain angle, the rotating component continues to hit the next set of rotating components to generate electricity as the buoyancy ball falls down. This continues until the buoyancy ball falls from the last set of rotating components and re-enters the main pipe. The water pumped by the water pump continues to rise from the lower place to the higher place through the main pipe.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The water circulation and buoyancy ball power generation system of the present invention includes a circulation pipeline for circulating water flow. The circulation pipeline includes a main pipe for water flow from a low point to a high point. A plurality of buoyancy balls that can move upward with the water flow are provided in the main pipe. During the process of pumping the upward water flow, the buoyancy balls are simultaneously transported to a high point and then the water flow and buoyancy balls are separated. The separated water flow enters the water intake channel and is converted into electrical energy by a hydroelectric generator. The buoyancy balls transported to the high point enter the bypass channel and drive the rotating component to rotate during the falling process, so as to generate electricity.

[0020] 2. The bypass channel includes a bypass pipe located below the last rotating component. The bypass pipe is equipped with a first valve and a second valve that can close the bypass. Both valves are one-way valves; after the buoyancy ball pushes open the valve and falls, the valve immediately springs back to close. The buoyancy ball flows into the main pipe with the water flow, entering the next cycle. The first valve prevents water from flowing upwards, avoiding interference with the rotating component and generator above.

[0021] 3. On the bypass pipe, the bypass pipe located between the first valve and the second valve is inclined to buffer the falling buoyancy ball. The bypass pipe near the second valve bends in the direction of water flow so that the buoyancy ball can smoothly follow the water flow into the main pipe and enter the next cycle after coming out of the bypass pipe.

[0022] 4. A drain pipe is installed between the main pipe and the water intake channel to allow water from the main pipe to flow into the water intake channel. Multiple drain pipes are arranged vertically and protrude from the main pipe, with the length of the protruding drain pipes increasing from bottom to top to guide the upward-moving buoyancy ball to one side of the bypass channel. While draining water, the drain pipes also propel the buoyancy ball smoothly into the bypass channel. The structure is simple and ingeniously designed.

[0023] 5. In the water circulation and buoyancy ball power generation system of the present invention, the hydroelectric generator can be installed on both the left and right sides of the main shaft. The rotating component is rotatably mounted on the main shaft, and generators can also be connected to both the left and right sides of the rotating component on the main shaft. Generators can also be connected to both the left and right sides of the impeller on the main shaft of the water pump. Installing generators on both sides allows for dual power generation, resulting in a high energy conversion rate. Simultaneously, it facilitates maintaining balance on both sides and simplifies the installation structure of the generator set or generator. The electrical energy converted by the generator can be stored in a battery or supplied to the drive motor of the water pump or other external equipment.

[0024] 6. The water circulation and buoyancy ball power generation method of the present invention simultaneously transports buoyancy balls to a higher position while pumping upward-moving water flow. The water flow and buoyancy balls circulate within a system consisting of a main pipe, a bypass channel, a water intake channel, and a return pipe. Multiple sets of hydraulic generators and multiple sets of rotating components are installed in the water intake channel and bypass pipe. The rotating components drive the generators to generate electricity during rotation, thus recovering energy. Water flow from lower to higher positions and from higher to lower positions is effectively utilized. [Image Description]

[0032] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0033] like Figure 1 The illustrated water circulation and buoyancy ball power generation system includes a circulation pipe 1 for circulating water flow. The circulation pipe 1 includes a main pipe 2 for water flow from a lower to a higher position. The main pipe 2 contains a plurality of buoyancy balls 3 that can move upward with the water flow. A bypass channel 4 is connected to the main pipe 2 for the buoyancy balls 3 to enter and fall. The main pipe 2 is provided with a water intake channel 5 connected to the main pipe 2 for guiding the water flowing out of the main pipe 2 to a lower position. A hydroelectric generator 6 is installed on the water intake channel 5. A rotating component 7 that can be driven to rotate by the falling buoyancy balls 3 is installed on the bypass channel 4. A generator is connected to the rotating component 7. A water pump 8 is installed on the circulation pipe 1 to transport water flow into the main pipe 2. The circulation pipe 1 also includes a return pipe 9 for returning the water flow from the water intake channel 5 to the water pump 8. The power generation system of the present invention simultaneously transports a buoyant ball to a higher position while the water pump is pumping water from a lower position to a higher position. The water is then diverted to a higher position. As the diverted water flows to a lower position, it is converted into electrical energy by a hydroelectric generator. At the same time, the buoyant ball transported to a higher position drives a rotating component to rotate during its descent, causing the generator to generate electricity.

[0034] Water intake channels can be closed pipes, such as water-cooling pipes in water-cooling systems or water supply pipes in water supply systems. Water intake channels can also include open channels, where water flowing from high to low can be used for cleaning, and a water collection device is installed below the cleaned object to collect the water before it continues to flow down the water intake channel.

[0035] The buoyancy ball 3 can be a hollow buoyancy ball or a buoyancy ball of other structures that can move upwards with the water flow. Preferably, the buoyancy of the buoyancy ball in the water is greater than or equal to the weight of the buoyancy ball.

[0036] The water pump 8 can be a booster pump, or it can be a booster device added to the pipeline to provide internal pressure to achieve the upward movement of water flow.

[0037] The bypass channel 4 includes a bypass pipe 41 located below the last rotating assembly 7. The bypass pipe 41 is equipped with a first valve 100 and a second valve 200 that can close the bypass pipe 41. The first valve 100 and the second valve 200 are one-way valves that can be pushed open downwards by a falling buoyancy ball 3. The first valve 100 and the second valve 200 automatically close after the buoyancy ball 3 passes through. The bottom end of the bypass pipe 41 is connected to the main pipe 2. The second valve 200 is located at the connection between the bypass pipe 41 and the main pipe 2. The first valve 100 and the second valve 200 are spaced apart so that two or more buoyancy balls 3 can be stacked between them to push open the second valve 200, allowing the buoyancy ball 3 to enter the main pipe 2. Since the first valve 100 and the second valve 200 are one-way valves, after the buoyancy ball pushes open the valve and falls, the valve immediately springs back and closes, allowing the buoyancy ball to flow into the main pipe with the water flow and enter the next cycle. Further, as... Figure 1 As shown, the first valve is positioned higher than the second valve within the bypass pipe 41. The first valve prevents water from flowing upwards, thus avoiding interference with the rotating components and generator above. The first valve 100 can be designed to be opened by the weight of a single buoyant ball. Due to water pressure within the pipe, the second valve can be designed to be opened by two or more buoyant balls.

[0038] The bypass pipe 41 located between the first valve 100 and the second valve 200 is inclined to cushion the falling buoyancy ball. The bypass pipe 41 near the second valve 200 bends in the direction of water flow. This allows the buoyancy ball to smoothly follow the water flow into the main pipe after exiting the bypass channel.

[0039] like Figure 1 As shown, the bypass channel 4 can be a closed pipe. The bypass channel can also include an open channel and a segmented pipe. The rotating assembly 7 is mounted on the pipe.

[0040] like Figure 1 and 3 As shown, a water inlet channel 10 is provided between the main pipe 2 and the water inlet channel 5 to allow water from the main pipe 2 to flow into the water inlet channel 5. The total water flow area of ​​the water inlet channel 10 is larger than the cross-sectional area of ​​the main pipe 2.

[0041] The water inlet channel 10 includes an inlet 101 located at the upper end of the water intake channel 5. A drain pipe 102 is provided between the main pipe 2 and the water intake channel 5 to allow water from the main pipe 2 to flow into the water intake channel 5. The upper end of the bypass channel 4 is higher than the drain pipe 102 and the inlet 101 of the water intake channel 5 to prevent water from flowing into the bypass channel. The inlet 101 is smaller than the diameter of the buoyancy ball 3, and the diameter of the drain pipe 102 is smaller than the diameter of the buoyancy ball 3 to prevent the buoyancy ball from entering the water intake channel.

[0042] Of course, the water inlet channel can also be set to have only a water inlet or a drain pipe.

[0043] like Figure 3 As shown, multiple drain pipes 102 are arranged vertically and protrude from the main pipe 2. The length of the drain pipes 102 protruding from the main pipe 2 from bottom to top increases to guide the upward-moving buoyancy ball 3 to one side of the bypass channel 4, so that the buoyancy ball can enter the bypass channel more smoothly.

[0044] like Figure 2 As shown, the upper end of the main pipe 2 is also provided with a guide rod 21 for pushing the buoyancy ball 3 into one side of the bypass channel 4.

[0045] The water circulation and buoyancy ball power generation system of the present invention consists of a main pipe 2, a bypass channel 4, a water intake channel 5 and a return pipe 9. The system can be set as a single set or multiple sets can be set in parallel. The water pump 8 is provided with a main pipe 11 that supplies water to multiple sets of main pipes 2. The water pump 8 is provided with a main return pipe 12 that collects and returns the water flow from multiple sets of return pipes 9, so as to recycle water resources.

[0046] like Figure 5 As shown, the hydroelectric generator 6 includes a main shaft and rotatable blade assemblies 61 mounted on the main shaft. Generator sets 62 are connected to both the left and right sides of the blade assemblies 61 on the main shaft. The blade assemblies 61 are driven to rotate by the water flow in the water inlet channel 5. The presence of generator sets on both sides facilitates maintaining balance. The presence of generator sets on both sides results in a high conversion rate for hydroelectric power generation. The water flow channel above each hydroelectric generator 6 is wider at the top and narrower at the bottom. The water inlet above the hydroelectric generator is narrowed to pressurize the water. Figure 5 As shown, the water outlet below the hydroelectric generator gradually increases in size to facilitate rapid water discharge and prevent water accumulation that could hinder the operation of the hydroelectric generator.

[0047] like Figure 6 As shown, the rotating component 7 is installed in the bypass channel 4 via a main shaft, and generators are connected to both the left and right sides of the rotating component 7 on the main shaft. Having generators on both sides allows for dual power generation, resulting in a high energy conversion rate.

[0048] like Figure 1 As shown, the rotating assembly 7 includes rotating blades 71, with several rotating blades 71 arranged circumferentially around a main shaft. Each rotating blade 71 has a groove 72 for a buoyant ball 3 to fall into, thus driving the rotating blade 71 to rotate. The groove is designed so that the rotating blade catches the buoyant ball, thereby driving the rotating blade to rotate. A generator connected to the rotating assembly converts mechanical energy into electrical energy. After the rotating blade rotates downwards by a certain angle, the buoyant ball in the groove automatically detaches from the groove and continues to fall.

[0049] The water pump 8 includes a main shaft and an impeller 81 mounted on the main shaft. The main shaft is driven to rotate by a power source such as an electric motor, which in turn drives the impeller 81 to rotate. Generators are connected to both sides of the impeller 81 on the main shaft. The generators on both sides of the impeller convert mechanical energy into electrical energy, achieving a certain degree of energy recovery from the electrical energy consumed by the drive motor.

[0050] The generator of this invention can be a magnetic generator, a magnetic generator with an iron core, a permanent magnet coreless magnetic generator, a single-ring magnetic generator, or a magnetic generator with double magnetic rings as described in patent document No. 201921575025.9, etc. The electrical energy converted by the hydroelectric generator or generator can be stored in a battery or supplied to the drive motor of a water pump or other external equipment.

[0051] A water circulation and buoyancy ball power generation method involves pumping water through a water pump 8 and sending it to a higher location via a main pipe 2. The water flow in the main pipe 2 pushes a buoyancy ball 3 upwards, causing it to rise to the top. Once the water reaches the top of the main pipe 2, the buoyancy ball 3 is sent to a bypass pipe 4. Simultaneously, water flows out of the main pipe 2 and into a water intake channel 5, which guides the water from a higher location to a lower location. During this downward flow, the water drives a hydroelectric generator 6 to generate electricity. After reaching the lower location, the water flows back to the water tank or pump through a return pipe 9. Water pump 8 continues to pump water to higher ground from point 8, while buoyancy ball 3 falls from top to bottom in bypass pipe 4. During its fall, it impacts rotating component 7, causing it to rotate. Rotating component 7 drives a generator to produce electricity. After rotating a certain angle, buoyancy ball 3 falls to the next set of rotating components 7, continuing to generate electricity until it falls from the last set of rotating components 7 and re-enters the main pipe 2. The water pumped by water pump 8 continues to rise from lower to higher ground through main pipe 2. During the upward flow of water using pumps, buoyancy ball 3 is simultaneously transported to higher ground, where the water flow and buoyancy ball are separated. The separated water flow enters the water intake channel, where a hydroelectric generator converts water energy into electrical energy. The buoyancy ball, transported to higher ground, enters the bypass channel and, during its descent, drives the rotating component to rotate, causing the generator to produce electricity. The water flow and buoyancy ball circulate within the system consisting of main pipe 2, bypass channel 4, water intake channel 5, and return pipe 9. Multiple sets of hydraulic generators and multiple sets of rotating components 7 are installed in water intake channel 5 and bypass pipe 4. The rotating components 7 drive the generators to generate electricity during rotation, thereby recovering energy.
