The first valve and the second valve are arranged at intervals for two or more buoyancy balls to be stacked between the first valve and the second valve to push the second valve open for the buoyancy balls to enter the main pipe.

[0007] A water cycle and buoyancy ball power generation system as 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 towards the water flow direction.

[0008] A water cycle and buoyancy ball power generation system as described above, an inlet channel for the water flow in the main pipe to flow into the diversion channel is provided between the main pipe and the diversion channel.

[0009] A water cycle and buoyancy ball power generation system as described above, the inlet channel includes a water inlet provided at the upper end of the diversion channel, a drain pipe for the water flow in the main pipe to flow into the diversion channel is provided between the main pipe and the diversion channel, the upper end of the bypass channel is higher than the drain pipe and the water inlet of the diversion channel, the water 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] A water cycle and buoyancy ball power generation system as described above, a plurality of the drain pipes are arranged vertically and protrude in the main pipe, and the lengths of the drain pipes protruding in the main pipe from bottom to top increase from short to long to guide the upward moving buoyancy ball to one side of the bypass channel.

[0011] A water cycle and buoyancy ball power generation system as described above, the total water flow area of the inlet channel is larger than the cross-sectional area of the main pipe.

[0012] A water cycle and buoyancy ball power generation system as described above, multiple systems composed of the main pipe, the bypass channel, the diversion channel and the return pipe are arranged in parallel, a main pipe for supplying water to multiple main pipes is provided on the water pump, and a total return pipe for collecting and returning the water flow of multiple return pipes is provided on the water pump.

[0014] A water cycle and buoyancy ball power generation system as described above, the rotating assembly is installed in the bypass channel through a main shaft. Generators are connected to both the left and right sides of the main shaft where the rotating assembly is located. The rotating assembly includes rotating blades, and a plurality of the rotating blades are arranged circumferentially around the main shaft.

[0015] A water cycle and buoyancy ball power generation system as described above, the water pump includes a main shaft and an impeller that can rotate and is installed on the main shaft. The main shaft is driven to rotate by a power source and then drives the impeller to rotate. Generators are connected to both the left and right sides of the main shaft where the impeller is located.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] 1. The water circulation and buoyancy ball power generation system of the utility model includes a circulation pipeline for the circulating flow of water. The circulation pipeline includes a main pipe for the water flow to flow from a low place to a high place. By arranging a number of buoyancy balls in the main pipe that can move upward following the water flow, when the water pump conveys the upward moving water flow, the buoyancy balls are simultaneously conveyed to a high place, and then the water flow and the buoyancy balls are separated. The separated water flow enters the diversion channel, and the water energy is converted into electric energy through a hydraulic generator. The buoyancy balls conveyed to the high place enter the bypass channel, and during the falling process, they push the rotating assembly to rotate to generate electricity for the generator.

[0018] 2. The bypass channel includes a bypass pipe. The bypass pipe is located below the last rotating assembly. The bypass pipe is provided 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. After the buoyancy ball pushes open the valve and falls, the valve will immediately bounce back to close. The buoyancy ball flows along with the water flow into the main pipe and enters the next cycle of movement. The first valve can prevent the water from flowing upward and avoid affecting the operation of the rotating assembly and the generator above.

[0019] 3. On the bypass pipe, the bypass pipe between the first valve and the second valve is inclined to buffer the falling buoyancy ball. The bypass pipe near the second valve bends towards the water flow direction, facilitating the buoyancy ball to smoothly follow the water flow into the main pipe and enter the next cycle after coming out of the bypass pipe.

[0020] 4. A drain pipe for the water flow in the main pipe to flow into the diversion channel is arranged between the main pipe and the diversion channel. By arranging a plurality of drain pipes in an up-and-down arrangement and protruding in the main pipe, the length of the drain pipes protruding in the main pipe from bottom to top gradually increases to guide the upward moving buoyancy balls to one side of the bypass channel. The drain pipe can not only drain water but also smoothly push the buoyancy balls into the bypass channel. The structure is simple and the design is ingenious.

[0021] 5. In the water circulation and buoyancy ball power generation system of the utility model, generator sets can be arranged on both the left and right sides of the main shaft of the hydraulic generator. The rotating assembly is rotatably installed on the main shaft, and generators can also be connected to both the left and right sides of the main shaft where the rotating assembly is located. Generators can also be connected to both the left and right sides of the main shaft of the water pump where the impeller is located. Arranging generators on both sides can generate electricity in a double way, with a high energy conversion rate. At the same time, it is also convenient to maintain the balance on both sides and simplify the installation structure of the generator set or the generator. The electric energy converted by the generator can be stored in a storage battery, or supplied to the driving motor of the water pump for use or other external devices for use.

[0029] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0030] like Figure 1 The water circulation and buoyancy ball power generation system shown includes a circulation pipeline 1 for circulating water flow, the circulation pipeline 1 includes a main pipe 2 for water flow from a low place to a high place, a plurality of buoyancy balls 3 that can move upward with the water flow are provided in the main pipe 2, the main pipe 2 is connected to a bypass channel 4 for the buoyancy balls 3 moving upward in the main pipe 2 to enter and fall, the main pipe 2 is provided with a water diversion channel 5 connected to the main pipe 2 and used to divert water flowing out of the main pipe 2 to a lower place, a hydroelectric generator 6 is installed on the water diversion 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, and a generator is connected to the rotating component 7, a water pump 8 for transporting water into the main pipe 2 is installed on the circulation pipeline 1, and the circulation pipeline 1 also includes a return pipe 9 that can return the water flowing out of the water diversion channel 5 to the water pump 8. The power generation system of the utility model transports the buoyancy ball to the high place and then diverts the water flow when the water pump pumps water from a low place to a high place. The water energy is converted into electrical energy by the hydroelectric generator when the diverted water flow flows to the low place. At the same time, the buoyancy ball transported to the high place pushes the rotating component to rotate during the falling process, so that the generator generates electricity.

[0031] The water diversion channel can be an enclosed pipeline, such as the water cooling pipeline used in a water cooling system and the water supply pipeline in a water supply system. The water diversion channel can also include an open channel. When water flows from a high place to a low place, the water in the channel can be used for cleaning, and a water collecting device is arranged below the object to be cleaned to collect the water and then continue to flow downward along the water diversion channel.

[0032] Among them, the buoyancy ball 3 can be a buoyancy ball with a hollow interior, or a buoyancy ball with other structures that can move upward with the water flow in water. Preferably, the buoyancy of the buoyancy ball in water is greater than or equal to the gravity of the buoyancy ball.

[0033] The water pump 8 can be a booster pump, or it can be achieved by adding a pressurization device to the pipeline to provide the internal pressure of the main pipe to move the water flow upward.

[0034] The bypass channel 4 includes a bypass pipe 41. The bypass pipe 41 is located below the last rotating assembly 7. A first valve 100 and a second valve 200 that can close the bypass pipe 41 are arranged on the bypass pipe 41. The first valve 100 and the second valve 200 are one-way valves that can be pushed downward by the falling buoyancy ball 3. The first valve 100 and the second valve 200 can automatically close after the buoyancy ball 3 passes through. The bottom end of the bypass pipe 41 is communicated with the main pipe 2. The second valve 200 is arranged at the communication place between the bypass pipe 41 and the main pipe 2. The first valve 100 and the second valve 200 are arranged at intervals to allow two or more buoyancy balls 3 to stack between the first valve 100 and the second valve 200 to push open the second valve 200 for the buoyancy ball 3 to enter the main pipe 2. 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 will immediately bounce back and close. The buoyancy ball flows into the main pipe along with the water flow and enters the next cycle. Further, as Figure 1 shown, the height of the first valve in the bypass pipe 41 is higher than that of the second valve. The first valve can prevent water from flowing upward and avoid affecting the operation of the rotating assembly and the generator above. Among them, the first valve 100 can be designed to be pushed open by the weight of one buoyancy ball. Due to the water pressure in the pipeline, the second valve can be designed to be pushed open by two or more buoyancy balls.

[0035] The bypass pipe 41 located between the first valve 100 and the second valve 200 is inclined to buffer the falling buoyancy ball. The bypass pipe 41 near the second valve 200 bends toward the water flow direction. It is convenient for the buoyancy ball to smoothly follow the water flow into the main pipe after coming out of the bypass channel.

[0036] As Figure 1 shown, the bypass channel 4 can be an enclosed pipeline. The bypass channel can also include an open channel and a segmented pipeline. The rotating assembly 7 is installed on the pipeline.

[0037] As Figure 1 and 3 shown, an inlet channel 10 for the water flow in the main pipe 2 to flow into the diversion channel 5 is provided between the main pipe 2 and the diversion channel 5. Among them, the total water flow area of the inlet channel 10 is larger than the cross-sectional area of the main pipe 2.

[0038] The inlet channel 10 includes a water inlet 101 provided at the upper end of the diversion channel 5. A drain pipe 102 for the water flow in the main pipe 2 to flow into the diversion channel 5 is provided between the main pipe 2 and the diversion channel 5. The upper end of the bypass channel 4 is higher than the drain pipe 102 and the water inlet 101 of the diversion channel 5 to prevent water flow from flowing into the bypass channel. The water 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 diversion channel.

[0039] Of course, the inlet channel can also be set to have only a water inlet or a drain pipe.

[0040] As Figure 3 shown, a plurality of the drain pipes 102 are arranged vertically and protrude in the main pipe 2. The length of the drain pipes 102 protruding in the main pipe 2 from bottom to top increases from short to long 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.

[0041] As Figure 2 shown, a guide rod 21 for pushing the buoyancy ball 3 into one side of the bypass channel 4 is further provided at the upper end of the main pipe 2.

[0042] For the water circulation and buoyancy ball power generation system of the present utility model, the system composed of the main pipe 2, the bypass channel 4, the diversion channel 5 and the return pipe 9 can be set as a single group, or multiple groups can be arranged in parallel, and a main pipe 11 for supplying water to multiple groups of main pipes 2 is provided on the water pump 8, and a total return pipe 12 for collecting and returning the water flow of multiple groups of return pipes 9 is provided on the water pump 8, realizing the recycling of water resources.

[0043] As Figure 5 shown, the hydraulic generator 6 includes a main shaft and a blade assembly 61 rotatably mounted on the main shaft. Generator sets 62 are connected to both the left and right sides of the main shaft where the blade assembly 61 is located. The blade assembly 61 is driven to rotate by the water flow in the diversion channel 5. Generator sets are arranged on both the left and right sides to facilitate maintaining the balance of both sides. Generator sets are provided on both the left and right sides, and the conversion rate of hydraulic power generation is high. Among them, the water flow channel above each hydraulic generator 6 is wider at the top and narrower at the bottom. The water inlet above the hydraulic generator is reduced, which can pressurize the water. As Figure 5 shown, the water flow outlet below the hydraulic generator changes from small to large, which is conducive to the rapid discharge of water flow to prevent water accumulation and hinder the operation of the hydraulic generator.

[0044] like Figure 6 As shown, the rotating assembly 7 is installed in the bypass channel 4 through a main shaft, and generators are connected to the main shaft on both the left and right sides of the rotating assembly 7. Generators are set on both the left and right sides to enable dual power generation, with a high energy conversion rate.

[0045] like Figure 1 As shown, the rotating assembly 7 includes rotating blades 71, which are arranged circumferentially around the main axis. Each blade 71 is provided with a groove 72 into which the falling buoyant balls 3 fall, thereby driving the rotating blades 71. The groove is designed so that the rotating blades catch the buoyant balls, thereby driving the rotating blades. A generator connected to the rotating assembly converts mechanical energy into electrical energy. After the rotating blades rotate downward a certain angle, the buoyant balls in the grooves automatically detach and continue to fall.

[0046] The water pump 8 includes a main shaft and an impeller 81 rotatably mounted on the main shaft. The main shaft is driven by a power source such as a motor to rotate the impeller 81. Generators are connected to the main shaft on both sides of the impeller 81. The generators on both sides of the impeller convert mechanical energy into electrical energy, thereby achieving a certain energy recovery effect on the electrical energy consumed by the drive motor.

[0047] The generator of the present invention can be a magnetic generator, a magnetic generator with an iron core, a permanent magnet coreless magnetic generator, a single magnetic ring magnetic generator, or a magnetic generator with double magnetic rings as described in patent document No. 201921575025.9. The electrical energy converted by the hydroelectric generator or generator can be stored in a battery or supplied to a water pump drive motor or other external equipment.

[0048] A water cycle and buoyancy ball power generation method pumps water through a water pump 8 and sends it to a high place through a main pipe 2. The water flow in the main pipe 2 pushes the buoyancy ball 3 in the main pipe 2 upward and makes it rise to a high place. After the water flow rises to the upper end of the main pipe 2, the buoyancy ball 3 is sent to a bypass pipe 4. At the same time, the water flow flows out of the main pipe 2 and enters a water diversion channel 5, and the water is diverted from a high place to a low place through the water diversion channel 5. During the process of the water flow flowing from a high place to a low place in the water diversion channel 5, a hydraulic generator 6 is driven to generate electricity. After the water flow reaches a low place, the water is returned to a water tank or the water pump 8 through a return pipe 9 to supply the water pump 8 to continue pumping water to a high place. The buoyancy ball 3 falls from top to bottom in the bypass pipe 4 and impacts a rotating assembly 7 during the falling process to push the rotating assembly 7 to rotate. The rotating assembly 7 drives a generator to generate electricity during the rotation process, and after the rotating assembly 7 rotates by an angle, the buoyancy ball 3 continues to fall and impacts the next set of rotating assemblies 7 to generate electricity until the buoyancy ball 3 enters the main pipe 2 again after falling from the last set of rotating assemblies 7, and the buoyancy ball 3 is continuously pumped by the water flow of the water pump 8 and rises from a low place to a high place through the main pipe 2. The upward moving water flow pumped by the water pump is used to simultaneously transport the buoyancy ball to a high place and then the water flow and the buoyancy ball are diverted. The diverted water flow enters the water diversion channel, and the water energy is converted into electrical energy through the hydraulic generator. The buoyancy ball transported to a high place enters the bypass channel and drives the rotating assembly to rotate during the falling process to generate electricity. The water flow and the buoyancy ball circulate and move within a system composed of the main pipe 2, the bypass channel 4, the water diversion channel 5, and the return pipe 9. Multiple sets of hydraulic generators and multiple sets of rotating assemblies 7 are arranged in the water diversion channel 5 and the bypass pipe 4. The rotating assembly 7 drives a generator to generate electricity during the rotation process for energy recovery.
