[0002] In recent years, with the continuous development of the global economy and society, countries have an increasing demand for energy. Traditional energy from fossil fuels can no longer meet the energy needs of various countries. The energy shortage problem has become increasingly prominent, and the global energy crisis has become more and more serious.

[0046] The present invention will be described in further detail below.

[0047] like Figure 1-Figure 3 As shown, a hydrostatic power generation device includes a runner mechanism 1, a high-pressure water pump 2 connected to a water reservoir 4, a plurality of pump body mechanisms 14, a control device and a generator 6;

[0048] The wheel mechanism 1 is provided with a circular wheel frame 13, which is arranged in the water reservoir 4 through the mounting frame 3 and can rotate in a vertical plane;

[0049] A plurality of pump mechanisms 14 are evenly distributed along the circumference of the runner mechanism 1 and are mounted on the runner mechanism 1 through the wheel frame 13. In this embodiment, the number of pump mechanisms 14 is 12, and at least one pump mechanism 14 is located below the water level of the water reservoir 4.

[0050] The high-pressure water pump 2 is respectively connected to a plurality of pump body mechanisms 14, and is used to deliver high-pressure water to the pump body mechanisms 14;

[0051] The control device is connected to the high-pressure water pump 2, and is used to control the timing of the high-pressure water pump 2 delivering high-pressure water to the pump body mechanism 14 so as to drive the pump body mechanism 14 located below the water level of the water reservoir 4 to suck water from the water reservoir 4 and spray water outward after leaving the water reservoir 4;

[0052] The pump body mechanism 14 is used to drive the wheel mechanism 1 to rotate by utilizing the reaction force formed by the outward water spraying;

[0053] The wheel mechanism 1 is connected to the generator 6 and is used to drive the generator 6 to generate electricity.

[0054] The control device controls the timing of the high-pressure water pump 2 delivering high-pressure water to the pump body mechanism 14, which can be set by a timing device. For example, the time when the pump body mechanism 14 enters and leaves the water reservoir 4 is calculated by the rotation speed of the wheel mechanism 1 and the action of the high-pressure water pump 2 is controlled accordingly to achieve water suction and water spraying by the pump body mechanism 14; an automatic sensing device can also be used to trigger the high-pressure water pump 2, such as arranging a pressure sensor on each pump body mechanism 14. When the pump body mechanism 14 enters the water reservoir 4, the pressure on the pressure sensor increases, and when it leaves the water reservoir 4, the pressure on the pressure sensor decreases, thereby triggering the high-pressure water pump 2 to act accordingly, thereby achieving water suction and water spraying by the pump body mechanism 14.

[0055] Preferably, the device of the present invention may further include a starting motor, which is connected to the control device and drivingly connected to the wheel mechanism 1. At the beginning of operation, the starting motor is used to drive the wheel mechanism 1 to rotate, so that the wheel mechanism 1 has an initial rotation speed at the beginning to drive the pump body mechanism 14 to rotate in and out of the water storage tank 4. When the reaction force formed by the pump body mechanism 14 spraying water outward is sufficient to drive the wheel mechanism 1 to rotate, the starting motor is stopped.

[0056] By using the device of the present invention to perform hydrostatic power generation, the power generation of the generator 6 is greater than the power consumption of the power unit of the device of the present invention, that is, more energy output can be obtained with a smaller energy input, thereby achieving low-cost, high-efficiency, and terrain-independent hydrostatic power generation, which has replicability and scalability, and provides a feasible way for clean energy power generation.

[0057] like Figure 4 As shown, the pump body mechanism 14 includes a water suction chamber 141, a double-headed piston 143, a high-pressure chamber 142, a first valve 161, a second valve 162, a water inlet pipe 152 and a first water outlet pipe 153. One end of the water suction chamber 141 and one end of the high-pressure chamber 142 are arranged correspondingly, and the other end of the water suction chamber 141 is provided with a common water inlet and outlet pipe 151, which is located on the outside of the wheel mechanism 1, and two ends of the double-headed piston 143 are respectively located in the water suction chamber 141 and the high-pressure chamber 142, and the double-headed piston 143 is slidably connected to the water suction chamber 141 and the high-pressure chamber 142, one end of the water inlet pipe 152 is connected to the high-pressure water pump 2, and the other end of the water inlet pipe 152 is respectively connected to the two ends of the high-pressure chamber 142 through the first valve 161, and the first water outlet pipe 153 is respectively connected to the two ends of the high-pressure chamber 142 through the second valve 162. The double-headed piston 143 includes a first piston, a second piston and a piston rod. The first piston is slidably connected to the water absorption cavity 141, and the second piston is slidably connected to the high-pressure cavity 142. The two ends of the piston rod are respectively connected to the first piston and the second piston. The diameter of the water absorption cavity 141 is larger than the diameter of the high-pressure cavity 142, and the diameter of the first piston is larger than the diameter of the second piston. A second water outlet pipe 154 is provided at one end of the water absorption cavity 141, and a third valve 163 is provided on the second water outlet pipe 154.

[0058] The water inlet and outlet common pipe 151 forms an angle of 90° with the water absorption cavity 141 and is tangent to the axis of the wheel frame 13. When the water absorption cavity 141 sprays water outward through the water inlet and outlet common pipe 151, the maximum reaction force can be obtained, thereby better driving the wheel mechanism 1 to rotate, and then driving the generator 6 to generate electricity.

[0059] In this embodiment, the water absorption cavity 141 and the high-pressure cavity 142 both include an inner cavity and an outer cavity. The inner cavity of the water absorption cavity 141 is connected to the inner cavity of the high-pressure cavity 142, and the outer cavity of the water absorption cavity 141 and the outer cavity of the high-pressure cavity 142 are respectively located at the two ends of the pump body mechanism 14. By controlling the first valve 161, the water inlet pipe 152 is respectively connected to the inner cavity and the outer cavity of the high-pressure cavity 142, so that the double-headed piston 143 can move toward the outer side and the inner side of the high-pressure cavity 142 respectively. By controlling the second valve 162, the first water outlet pipe 153 is connected to the outer cavity of the high-pressure cavity 142, so that the water in the outer cavity of the high-pressure cavity 142 can be discharged. By controlling the third valve 163, the second water outlet pipe 154 is connected to the inner cavity of the water absorption cavity 141, so that the water in the inner cavity of the water absorption cavity 141 can be discharged.

[0060] Furthermore, the first valve 161 and the second valve 162 are both two-way motorized valves, and the third valve 163 is a single-way motorized valve. Since the pump mechanism 14 enters the water reservoir 4 from top to bottom and leaves the water reservoir 4 from bottom to top in opposite directions, the water resistance of the water reservoir 4 can be used to automatically adjust the connection direction of each valve to achieve automatic water absorption and water spraying.

[0061] Alternatively, the first valve 161, the second valve 162 and the third valve 163 are all electromagnetic valves connected to the control device. When the pump body mechanism 14 enters and leaves the water reservoir 4, the connection direction of each electromagnetic valve is controlled accordingly to achieve automatic water absorption and water spraying.

[0062] like Figure 5 As shown, a diverter disc 11 is provided in the middle of the wheel mechanism 1, and the diverter disc 11 is located at the center of the wheel frame 13. The diverter disc 11 is provided with a plurality of diverter channels connected to the high-pressure water pump 2, and the plurality of diverter channels are respectively connected one-to-one with the water inlet pipes 152 of the plurality of high-pressure cavities 142. An array water inlet 111 is provided in the middle of the diverter disc 11, and an array water outlet 112 is provided on the outside of the diverter disc 11. The array water inlet 111 and the array water outlet 112 are respectively connected one-to-one to form a plurality of diverter channels, and the array water outlet 112 is connected to the water inlet pipe 152 of the high-pressure cavity 142. A universal water inlet pipe 12 is provided in the middle of the diverter disc 11, and the universal water inlet pipe 12 is connected to the array water inlet 111.

[0063] The high-pressure water of the high-pressure water pump 2 enters the array water inlet 111 through the universal water inlet pipe 12 in the middle of the diverter wheel 11, then flows out of the array water outlet 112 through the corresponding diverter channel, and then enters the corresponding pump body mechanism 14 from the array water outlet 112, and enters the high-pressure cavity 142 through the corresponding water inlet pipe 152.

[0064] like Figure 1As shown, it also includes an energy storage device 5 and an automatic circulating water system connected to the water reservoir 4.

[0065] The automatic circulating water system is used to keep the water level of the water reservoir 4 unchanged, which can not only make more efficient use of water resources, but also keep the relative position of the pump mechanism 14 and the water level of the water reservoir 4 unchanged, which is conducive to maintaining a relatively constant rotational driving force of the wheel mechanism 1, thereby achieving stable power generation by the generator 6.

[0066] The energy storage device 5 is connected to the generator 6 and is used to store the electric energy generated by the generator 6 .

[0067] A hydrostatic power generation method comprises the following steps:

[0068] The high-pressure water pump 2 delivers high-pressure water to the pump mechanism 14 located below the water level of the water reservoir 4, driving the pump mechanism 14 to absorb water from the water reservoir 4, and spraying water outward after the pump mechanism 14 rotates out of the water reservoir 4. The pump mechanism 14 sprays water outward to form a reaction force to drive the wheel mechanism 1 to rotate, and the wheel mechanism 1 drives the generator 6 to generate electricity;

[0069] During the rotation of the wheel mechanism 1 , the wheel mechanism 1 drives a plurality of pump mechanisms 14 evenly distributed along the circumference of the wheel mechanism 1 to enter and leave the water reservoir 4 in sequence to form a cycle.

[0070] The present invention drives the pump body mechanism 14 to absorb and spray water through the high-pressure water pump 2, thereby driving the wheel mechanism 1 to rotate and drive the generator 6 to generate electricity, so as to achieve a larger power output with a smaller energy input, thereby achieving the purpose of hydrostatic power generation.

[0071] like Figure 6 As shown, the pump mechanism 14 absorbs water by adjusting the first valve 161 so that the water inlet pipe 152 is connected to the inner cavity of the high-pressure cavity 142, and the high-pressure water pump 2 quickly fills the high-pressure water into the high-pressure cavity 142, pushing the double-headed piston 143 to move to the outside of the high-pressure cavity 142, and during the movement of the double-headed piston 143, negative pressure is formed in the outer cavity of the water absorption cavity 141, and the other end of the water absorption cavity 141 absorbs water from the water reservoir 4 to the outer cavity of the water absorption cavity 141 through the water inlet and outlet common pipe 151;

[0072] like Figure 7 As shown, the method for implementing water spraying by the pump body mechanism 14 is to adjust the first valve 161 so that the water inlet pipe 152 is connected to the outer cavity of the high-pressure cavity 142, and the high-pressure water pump 2 quickly fills the high-pressure water into the high-pressure cavity 142, pushing the double-headed piston 143 to move toward the outside of the water absorption cavity 141. During the movement of the double-headed piston 143, the water in the outer cavity of the water absorption cavity 141 is squeezed to increase its pressure and speed, and then sprayed outward through the inlet and outlet water common pipe 151.

[0073] By adjusting the first valve 161 , the double-headed piston 143 can be driven to move in different directions, thereby facilitating the pump body mechanism 14 to absorb and spray water.

[0074] Due to airtightness issues, water may penetrate into the inner cavity of the water absorption cavity 141 and the outer cavity of the high-pressure cavity 142 .

[0075] In this embodiment, when the pump body mechanism 14 absorbs water, the second valve 162 is adjusted to connect the first water outlet pipe 153 to the outer cavity of the high-pressure cavity 142, and the double-headed piston 143 moves toward the outside of the high-pressure cavity 142 to squeeze the water in the outer cavity of the high-pressure water cavity to spray outward;

[0076] When the pump mechanism 14 sprays water, the third valve 163 is adjusted to connect the second water outlet pipe 154 to the inner cavity of the water absorption cavity 141, and the double-headed piston 143 moves toward the outside of the water absorption cavity 141 to squeeze the water in the inner cavity of the water absorption cavity 141 to spray outward.

[0077] When the water in the outer cavity of the high-pressure cavity 142 and the inner cavity of the water absorption cavity 141 is sprayed outward, an auxiliary reaction force can be formed to assist in driving the wheel mechanism 1 to rotate, so that the wheel mechanism 1 can more easily drive the generator 6 to generate electricity, thereby improving the power generation efficiency.

[0078] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
