[0004] The present invention is achieved through the following technical solutions: A water gravity power generation device, comprising a generator flywheel and a water gravity device for driving the generator flywheel to rotate, wherein the water gravity device comprises a frame, an upper water tank, a movable water tank, a socket group, a latch, a latch switch, a middle water tank counterweight, a lower water tank counterweight, a water lifting tank, a lifting mechanism, a first rack and a first single-speed flywheel; The upper water tank is fixedly arranged on the top of the frame, and the two movable water tanks are slidably arranged on the frame. The two movable water tanks are respectively a middle water tank and a lower water tank. The frame serves as the installation base of each water tank. The bottoms of the upper water tank, the middle water tank and the lower water tank are all provided with valves. After the valves are opened, the water in each water tank can be discharged. The upper water tank is used to store water required for power generation. The middle water tank is located below the upper water tank and can hold the water dropped from the upper water tank. The lower water tank is located below the middle water tank and can hold the water dropped from the middle water tank. The frame is provided with a middle water tank filling level, a middle water tank discharge level, a lower water tank filling level and a lower water tank discharge level spaced from top to bottom. Both the middle water tank and the lower water tank can slide in the vertical direction between the corresponding filling level and discharge level on the frame; A socket group is fixedly arranged at the middle water tank filling level, the middle water tank draining level, the lower water tank filling level and the lower water tank draining level on the frame, and the socket group includes two left and right opposite plug seats, each of which is provided with a socket; The top and bottom of the middle water tank and the top and bottom of the lower water tank are both provided with two opposite latches, which can be correspondingly inserted into the sockets of the two opposite latch seats to fix the movable water tank on the frame; The upper and lower water tanks of the middle water tank are both provided with a latch switch for driving the latch to move in and out of the latch seat; when the middle water tank slides on the rack to the water filling level of the middle water tank, the latch switch on the middle water tank can drive the two latches on the top of the middle water tank to be respectively inserted into the two latch seats on the rack at the water filling level of the middle water tank to fix the middle water tank on the rack, the valve at the bottom of the upper water tank is opened, and water can be discharged into the middle water tank, and the valve at the bottom of the upper water tank is closed to stop the water discharge, and after the latch switch on the middle water tank drives the two latches on the top of the middle water tank to respectively withdraw from the two latch seats on the rack at the water filling level of the middle water tank, the middle water tank can slide downward on the rack to the water discharge level of the middle water tank under the action of gravity, and the two latches at the bottom of the middle water tank are respectively inserted into the two latch seats on the rack at the water discharge level of the middle water tank to discharge the middle water tank The water tank is fixed on the frame, at this time, the lower water tank is fixed at the water filling level of the upper and lower water tanks on the frame, the valve at the bottom of the middle water tank is opened, and water can be discharged into the lower water tank. After the water in the middle water tank is discharged, the latch switch on the lower water tank drives the two latches on the top of the lower water tank to respectively withdraw from the two latch seats of the water filling level of the upper and lower water tanks on the frame, and the lower water tank can slide downward on the frame to the water discharge level of the lower water tank under the action of gravity, and the two latches at the bottom of the lower water tank are respectively inserted into the two latch seats of the water discharge level of the upper and lower water tanks on the frame to fix the lower water tank on the frame; when the middle water tank is filled with water at the middle water tank filling level on the frame, the lower water tank is discharged at the water discharge level of the upper and lower water tanks on the frame, and a cycle is formed in this way; The middle water tank counterweight is connected to the middle water tank by a steel wire rope. The middle water tank counterweight is used to drive the empty middle water tank to rise from the middle water tank discharge level on the frame to the middle water tank filling level. When the middle water tank filled with water at the middle water tank filling level slides downward on the frame, the middle water tank counterweight can be driven to rise. Conversely, after the middle water tank is emptied of water, the middle water tank counterweight descends and drives the middle water tank to slide upward on the frame to reset it. The lower water tank counterweight is connected to the lower water tank by a steel wire rope. The lower water tank counterweight is used to drive the lower water tank to rise from the lower water tank discharge level on the frame to the lower water tank filling level. When the lower water tank filled with water at the lower water tank filling level slides downward on the frame, the lower water tank counterweight can be driven to rise. Conversely, after the lower water tank is emptied of water, the lower water tank counterweight descends and drives the lower water tank to slide upward on the frame to reset it. The lifting mechanism is used to drive the lifting of the water lifting tank. A valve is provided at the bottom of the water lifting tank. A water lifting tank filling level and a water lifting tank discharge level are provided at the bottom and the top of the frame respectively. The lifting mechanism is used to drive the water lifting tank to switch between the water lifting tank filling level and the water lifting tank discharge level. The water lifting tank is used to load the water discharged from the lower water tank at the water lifting tank filling level and then be lifted to the water lifting tank discharge level by the lifting mechanism to discharge the water into the upper water tank. When the lower water tank is located at the lower water tank discharge level on the frame, the water lifting tank is located at the water lifting tank filling level on the lower side of the lower water tank. After the valve at the bottom of the lower water tank is opened, water can be put into the water lifting tank. When the lower water tank rises, the water lifting tank is lifted by the lifting mechanism to the water lifting tank discharge level on the upper side of the upper water tank. After the valve at the bottom of the water lifting tank is opened, water can be put into the upper water tank, thereby forming a recycling of water. The first rack is installed on the middle water tank counterweight, and the first single-speed flywheel is installed on the rotating shaft of the generator flywheel. The first single-speed flywheel is meshed with the first rack. When the middle water tank counterweight rises, the first single-speed flywheel is driven to rotate through the first rack to drive the generator flywheel to rotate. When the middle water tank counterweight descends, the first rack descends accordingly. Under the action of the first single-speed flywheel, the first rack can be prevented from driving the first single-speed flywheel to rotate in the opposite direction.

[0005] Furthermore, the lifting mechanism includes a bracket, a main lever, a lifting lever, a main counterweight, a lever pressing mechanism and a pressing switch; the middle part of the main lever is rotatably installed in the middle part of the bracket, the middle part of the lifting lever is rotatably installed in the left end of the main lever, the main counterweight is fixedly installed in the right end of the main lever, a fixed pulley is installed at the bottom of the bracket, a steel wire rope is wound around the fixed pulley, two ends of the steel wire rope are respectively fixed to the right end of the lifting lever and the left end of the main lever, the left end of the lifting lever is rotatably connected to the top of the water lifting tank, and the lever pressing mechanism is installed on the bracket for The left end of the main lever is pressed down to control the water lifting tank at the water filling level of the water lifting tank. The pressing switch is used to control the lever pressing mechanism to press down the main lever or release it. After the lower water tank discharges all the water into the water lifting tank at the water filling level of the water lifting tank, the pressing switch is opened while the lower water tank rises, and the lever pressing mechanism releases the downward pressure on the left end of the main lever. Under the action of the gravity of the main counterweight, the main counterweight can press down the right end of the main lever, so that the left end of the main lever rotates upward. The wire rope pulls the lifting lever to rotate, thereby lifting the water lifting tank to the water discharge level of the water lifting tank.

[0006] Furthermore, the lever pressing mechanism includes a rocking lever, a rocking counterweight, an inclined platform, a movable counterweight and a reel, and the pressing switch includes a second rack, a second single-speed flywheel and a locking mechanism; the middle part of the rocking lever is rotatably mounted on the upper part of the bracket, the inclined platform is fixed to the left end of the rocking lever, a fixed pulley is mounted on the top of the bracket, and a steel wire rope is wound around the fixed pulley, and the two ends of the steel wire rope are respectively connected to the first movable counterweight and the second movable counterweight, and the first movable counterweight is slidably arranged on the inclined platform, and the inclined platform is provided with a high position and a low position of the stroke of the first movable counterweight, and the first movable counterweight can be The first movable counterweight slides between the high position and the low position of the stroke, and the left end of the swing lever presses down the left end of the main lever when the stroke is low. The drum is fixedly mounted on the bracket, and a steel wire rope is wound on the drum, and the movable end of the steel wire rope is connected to the second movable counterweight. The lower water tank counterweight is slidably mounted on the bracket, and the second rack is fixedly mounted on the lower water tank counterweight. The second single-speed flywheel is mounted on the rotating shaft of the drum, and the second single-speed flywheel is meshed with the second rack. When the lower water tank counterweight descends, it drives the second rack to descend, and the second rack drives the second single-speed flywheel to rotate to drive the drum to wind up the steel wire rope. When the counterweight rises, the second rack rises accordingly. Under the action of the second single-speed flywheel, the second rack is prevented from driving the second single-speed flywheel to rotate in the opposite direction, so that the reel remains stationary. Only when the second rack descends will the reel be driven to reel in the wire rope to drive the first movable counterweight to slide upward on the inclined platform to the high position of the stroke. The locking mechanism is arranged at the high position of the stroke on the inclined platform to fix the first movable counterweight on the inclined platform. When the first movable counterweight slides to the high position of the stroke, it can be fixed on the inclined platform by the locking mechanism. At this time, the swing counterweight presses down the right end of the swing lever to make it rotate, and the left end of the swing lever rotates upward to The downward pressure on the left end of the main lever is released so that the lifting mechanism can lift the water tank. After the water in the water tank is drained to the water discharge level, the locking mechanism opens, and the first movable counterweight can slide downward to the low position of the stroke under the action of its gravity, and drive the second movable counterweight to rise and the drum to unwind the wire rope. Under the action of the gravity of the first movable counterweight, the swing lever can be driven to rotate, and the left end of the swing lever presses down the left end of the main lever, causing the left end of the main lever to rotate downward. While the main lever rotates, the lifting lever is pulled to rotate by the wire rope, and the rotation of the lifting lever can lower the water tank to the water filling level of the water tank.

[0007] Furthermore, a turbine is provided at the valve water outlet at the bottom of the upper water tank, and the rotating shaft of the turbine is transmission-connected to the rotating shaft of the generator flywheel. The water released from the upper water tank can first drive the rotating shaft of the turbine to rotate, so as to assist in driving the generator flywheel to rotate, thereby improving the power generation efficiency. After the water flows out of the turbine, it is discharged into the middle water tank, thereby improving the utilization rate of water.

[0008] Furthermore, water supply pipes are provided below the water discharge levels of the upper and lower water tanks of the frame and at the valve outlet at the bottom of the water lifting tank. The water outlet end of the water supply pipe is connected to an elastic hose. When the water lifting tank descends to the water filling level of the water lifting tank, the water lifting tank can press down the elastic hose at the water outlet end of the water supply pipe on the frame. After the water lifting tank descends into place, the elastic hose rebounds so that its water outlet extends into the water lifting tank, ensuring that water released from the lower water tank can be discharged into the water lifting tank through the water supply pipe. When the water lifting tank rises to the water discharge level of the water lifting tank, the elastic hose at the water outlet end of the water supply pipe at the bottom of the water lifting tank is squeezed by the upper water tank. After the water lifting tank rises into place, the elastic hose rebounds so that its water outlet extends into the upper water tank, ensuring that water released from the water lifting tank can be discharged into the upper water tank through the water supply pipe.

[0009] The present invention also provides a method for generating electricity using a water gravity power generation device, comprising the following steps: S1. Draining water from the upper water tank and filling water from the middle water tank: The middle water tank is located at the water filling level of the middle water tank on the rack, and the two latches on the top of the middle water tank are respectively inserted into the latch sockets at the water filling level of the middle water tank on the rack to fix the middle water tank on the rack. The valve at the bottom of the upper water tank is opened to discharge water into the middle water tank. After the middle water tank is filled with a preset amount of water, the valve at the bottom of the upper water tank is closed, and at the same time, the latch switch on the middle water tank drives the two latches on the top of the middle water tank to withdraw from the latch socket. The middle water tank slides downward on the rack to the water discharge level of the middle water tank under the action of gravity, and the two latches at the bottom of the middle water tank are respectively inserted into the latch sockets at the water discharge level of the middle water tank on the rack to fix the middle water tank on the rack; S2, generator flywheel rotation: In the above step S1, when the middle water tank descends from the middle water tank filling level to the middle water tank discharge level on the frame, the middle water tank drives the middle water tank counterweight to rise through the wire rope, and the first rack rises with the middle water tank counterweight. The first rack drives the first single-speed flywheel to rotate to drive the generator flywheel to rotate, and the generator flywheel rotates to drive the generator to generate electricity; S3, draining water from the middle water tank and filling water from the lower water tank: when the middle water tank slides on the rack to the middle water tank draining position, the lower water tank is located on the rack at the lower water tank filling position, and the two latches on the top of the lower water tank are respectively inserted into the latch seat sockets at the upper and lower water tank filling positions of the rack to fix the lower water tank on the rack, and the valve at the bottom of the middle water tank is opened to drain water into the lower water tank. After the water in the middle water tank is drained, the valve at the bottom of the middle water tank is closed, and at the same time, the latch switch on the lower water tank drives the two latches on the top of the lower water tank to withdraw from the latch seat, and the lower water tank slides downward on the rack to the lower water tank draining position under the action of gravity, and the two latches at the bottom of the lower water tank are respectively inserted into the latch seat sockets at the upper and lower water tank draining positions of the rack to fix the lower water tank on the rack; S4. Reset after draining the water from the middle water tank: After draining the water from the middle water tank at the draining level on the rack, the latch switch on the middle water tank drives the two latches at the bottom of the middle water tank to exit the latch seat, and the middle water tank counterweight descends under the action of its gravity, and drives the drained middle water tank to slide upward on the rack, so that the middle water tank slides on the rack to the filling level of the middle water tank, and the two latches on the top of the middle water tank are respectively inserted into the latch seat sockets at the filling level of the middle water tank on the rack to fix the middle water tank on the rack; S5, draining water from the lower water tank and filling water from the lifting water tank: when the lower water tank slides on the frame to the draining position of the lower water tank, the lifting mechanism controls the lifting water tank to the filling position of the lifting water tank, and the valve at the bottom of the lower water tank is opened to drain water into the lifting water tank. After the water in the lower water tank is drained, the valve at the bottom of the lower water tank is closed, and at the same time, the lifting mechanism lifts the lifting water tank to the draining position of the lifting water tank on the upper side of the upper water tank; S6. Reset the lower water tank after draining: After draining the lower water tank at the lower water tank draining position on the rack, the latch switch on the lower water tank drives the two latches at the bottom of the lower water tank to withdraw from the latch seat, and the lower water tank counterweight descends under the action of its gravity, and drives the drained lower water tank to slide upward on the rack, so that the lower water tank slides on the rack to the lower water tank filling level, and the two latches on the top of the lower water tank are respectively inserted into the latch seat sockets at the upper and lower water tank filling levels of the rack to fix the lower water tank on the rack; S7, draining and resetting the water lifting tank: the valve at the bottom of the water lifting tank is opened at the draining level of the water lifting tank to drain water into the upper water tank. After the water in the water lifting tank is drained, the lifting mechanism lowers the water lifting tank to the filling level of the water lifting tank; S8, continuous cycle power generation: after the water in the middle water tank is drained and reset to the water level of the middle water tank on the frame, repeat steps S1 to S7 to make the generator flywheel rotate continuously to drive the generator to generate electricity. In the above steps S3 to S7, the lower water tank and the lifting water tank return the water discharged from the middle water tank to the upper water tank to realize the recycling of water.

[0010] Furthermore, in the above step S1, the water released from the upper water tank first drives the shaft of the turbine to rotate, and the rotation of the shaft of the turbine drives the shaft of the generator flywheel to rotate, so as to assist in driving the generator flywheel to rotate, which can improve the power generation efficiency. After the water flows out of the turbine, it is discharged into the middle water tank, thereby improving the utilization rate of water.

[0011] Furthermore, in the above step S6, when the counterweight of the lower water tank descends, it drives the second rack to descend, and the second rack drives the second single-speed flywheel to rotate to drive the reel to wind up the wire rope. The wire rope drives the first movable counterweight to slide upward on the inclined platform to the high position of the stroke, and the locking mechanism fixes the first movable counterweight on the inclined platform. The swing counterweight presses down the right end of the swing lever to make it rotate, and the left end of the swing lever rotates upward to release the downward pressure on the left end of the main lever. Under the gravity of the main counterweight, the gravity counterweight presses down the right end of the main lever to make the left end of the main lever rotate upward, and the wire rope pulls the lifting lever to rotate, so that the water lifting tank can be lifted to the water discharge position of the water lifting tank.

[0012] Furthermore, in the above step S7, after the water is drained from the water lifting tank to the water discharge level, the locking mechanism opens, and the first movable counterweight slides downward to the low position of the stroke under the action of its gravity, and drives the second movable counterweight to rise and the drum to unwind the wire rope, and the swing lever rotates, and the left end of the swing lever presses down on the left end of the main lever, and the left end of the main lever rotates downward, and the lifting lever rotates with the main lever to lower the water lifting tank to the water filling level of the water lifting tank.

[0013] Furthermore, the water gravity power generation device is provided with two groups of water gravity devices, and the two groups of water gravity devices are used to alternately drive the generator flywheel to ensure that the generator flywheel can rotate continuously to improve the power generation efficiency.

[0014] It can be seen from the above technical solutions that the water gravity power generation device and power generation method provided by the present invention have the following beneficial effects: After the middle water tank of the water gravity power generation device is filled with water at the middle water tank filling level on the frame, it has a large gravitational potential energy, which can overcome the gravitational potential energy of the middle water tank counterweight. After the latch on the top of the middle water tank exits the latch seat, the middle water tank can slide downward to the middle water tank discharge level under the action of its gravity. During the process of the middle water tank sliding downward on the frame, it can generate tension and stroke and drive the middle water tank counterweight and the first rack to rise through the wire rope. The first rack can drive the generator flywheel to rotate by driving the first single-speed flywheel to rotate, and the generator When the flywheel rotates, it drives the generator to generate electricity; it can transfer water through the lower water tank and the water lifting tank, and transfer the water back to the upper water tank, so as to realize the recycling of water and continuous power generation. Compared with the existing hydroelectric power station, the water gravity power generation device only needs to add a sufficient amount of water in the upper water tank at the beginning for circulating power generation, so that it is not restricted by the site selection of rivers, lakes and reservoirs. The water gravity power generation device can be built on flat terrain, is easy to build, has a smaller scale, and can reduce construction and operation costs; the water gravity power generation device can generate electricity continuously during the circulation operation process.

The water lifting tank 7 can put water into the water distribution tank 24, and a three-way water distribution pipe 21 is arranged at the bottom of the water distribution tank 24. The water released from the water lifting tank 7 enters the water distribution tank 24, and then is diverted to the built-in water tank 19 and the upper water tank 2 through the three-way water distribution pipe 21. The bottom of the built-in water tank 19 is provided with a water distribution pipe for supplying counterweight water to the water distribution tank 24. The water outlet of the counterweight water tank 9.1 is provided at the bottom of the counterweight water tank 9.1. The water in the built-in water tank 19 is put into the counterweight water tank 9.1. After a certain amount of water is put into the counterweight water tank 9.1, its gravity is greater than the gravity of the water tank counterweight 9.2. The counterweight water tank 9.1 swings downward to make the first seesaw 9.4 rotate clockwise. The first seesaw 9.4 pulls the second seesaw 9.5 to rotate counterclockwise through the steel wire 17.

When the middle water tank 3 slides upward, the first valve push rod 28.1 rises with the middle water tank 3. When the middle water tank 3 slides to the water filling level 1.1 of the middle water tank, the first valve push rod 28.1 pushes the first valve seesaw 28.2, so that the first valve seesaw 28.2 rotates, thereby pulling the valve stem 15.3 upward through the steel wire 17 to open the valve plate 15.2, thereby opening the check valve at the bottom of the upper water tank 2, allowing the water in the upper water tank 2 to be discharged to the middle water tank 3. When the middle water tank 3 slides downward, the first valve push rod 28.1 moves downward and disengages from the first valve seesaw 28.2, and the compression spring 15.5 in the valve pushes the valve plate 15.2 back to close the check valve, and the upper water tank 2 stops discharging water; like Figures 2 to 6As shown, the check valve at the bottom of the middle water tank 3 and the check valve at the bottom of the lower water tank 4 are both installed at their outer bottoms, and a movable water tank valve switch 30 is provided on the mounting plate 16 of the middle water tank discharge level 1.2 and the mounting plate 16 of the lower water tank discharge level 1.4 on the frame 1. The movable water tank valve switch 30 includes a joint 30.1 and a second valve top rod 30.2 provided on the inner support of the joint 30.1. When the movable water tank (middle water tank 3 or lower water tank 4) slides downward to the discharge level on the frame 1, The bottom end of the check valve at the bottom is inserted into the joint 30.1 and abuts against the internal support of the joint 30.1 to ensure the transition of water.
