Description

Technical Field

[0001] The present invention relates to the technical field of clean energy power generation, and particularly to a hydrostatic power generation device for reuse. Background Art

[0002] The existing power generation modes are nuclear power, natural reservoir water storage, thermal power, wind power, and solar power generation. By using these energy sources, the generator is driven to rotate, cutting the magnetic field lines to generate electric energy. However, there are defects in using these methods for power generation. For example, nuclear power generation is restricted by policies, technologies, and conditions; hydropower is affected by natural resources and environmental control and is unable to expand; thermal power generation consumes a large amount of coal, oil, or biomass and causes environmental pollution; wind power generation is affected by the size of natural wind, resulting in poor power generation capacity and voltage stability; solar power generation has a short effective illumination time and cannot generate electricity all day long. When the direct current generated by solar energy is to be connected to the grid, it needs to be converted into alternating current through an inverter. In particular, the direct current needs to be stored and then converted into alternating current through an inverter to be connected to the grid, requiring a huge energy storage device, with too high investment costs and low economic benefits. Therefore, it is extremely urgent to develop a hydrostatic power generation device for reuse that is not affected by any natural environment and can generate electricity all day long.

[0003] For example, in the invention application with the inventor's application number 202510396568.8, a multi-functional gearbox system for power generation using mechanical energy, and the invention application with the application number 202510237132.4, a mechanical energy device for power generation, disclose a mechanical energy device for power generation, which has played a very good role in solving China's energy problems and laid a foundation for the technology of reusing clean water for power generation. Summary of the Invention

[0004] The object of the present invention is to provide a hydrostatic power generation device for reuse to generate electricity. By using a centrifugal water pump, the static water is lifted to the top of the hydraulic mechanical wheel and discharged into a semi-closed water energy tank. Under the action of the kinetic energy and potential energy of the discharged water in the water energy tank, mechanical energy is formed. The water wheel rotates under the action of the external force of mechanical energy, making a uniform circular motion to generate huge inertial energy storage. The potential energy of the large-mass water wheel is the height of the fixed diameter of the water wheel, and its kinetic energy speed is uniform, forming huge fixed mechanical energy. The wheel shaft of the hydraulic mechanical wheel is transmitted to the input port of the multi-functional gearbox. After changing the torque and speed through the gearbox, the speed and power required for power generation are provided for the generator. The generated electric energy is incorporated into the power supply network through the mechanical and electrical control system. It effectively solves the problem that the power energy of the generator is restricted by policies, energy, and natural environmental conditions, optimizes the power source of the existing power generation, and overcomes a series of defects of the existing new energy power generation restricted by natural environmental conditions. To solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A hydrostatic power generation device for reuse according to the present invention is characterized in that the hydrostatic power generation device for reuse is composed of a high-lift water pump, a water storage tank, a hydraulic mechanical wheel, a semi-closed water energy tank, a gearbox, a generator and an electromechanical control; the high-lift water pump is a motor-driven large-flow centrifugal pump; the water storage tank is arranged at the bottom end of the hydraulic mechanical wheel and has the function of replacing static water; the hydraulic mechanical wheel includes a water wheel shaft, a water wheel steel ring body support frame, a water wheel steel ring body and water wheel blades; an annular positioning water stop ring is arranged inside the outer surface edge of the water wheel steel ring body; the water wheel blades are made of steel plates and welded on the outer surface of the water wheel steel ring body, and the water wheel blades and the outer surface of the water wheel steel ring body form a water-containing angle of <75 degrees; the semi-closed water energy tank is a vertical water energy tank; an arc-shaped groove is formed at the lower part of the vertical water energy tank; the arc-shaped groove is arc-shapedly matched with the joint section of the hydraulic mechanical wheel; the gearbox is a gearbox; the gearbox is connected to the water wheel shaft, and after changing the torque and speed in the gearbox, it provides the required matching speed and power for the generator; the generator is a 50Hz AC generator; the water wheel shaft box, the gearbox and the generator are assembled on the same reinforced concrete foundation platform.

[0006] Further, the speed of the water power mechanical wheel is controlled by a multi-functional gearbox; the multi-functional gearbox inputs synchronous energy; the synchronous energy motor is speed-regulated by an inverter.

[0007] Further, the speed of the water power mechanical wheel is controlled by an inverter-regulated water pump motor to control the water flow.

[0008] Further, the water wheel blades on the hydraulic mechanical wheel rotate in the semi-closed water energy tank along with the hydraulic mechanical wheel.

[0009] Further, the vertical arc-shaped water energy tank starts to be semi-closed when the hydraulic mechanical wheel rotates clockwise to 0 degrees, and starts to form an arc matching the hydraulic mechanical wheel when it rotates to <60 degrees.

[0010] Further, the high-voltage generator is 10050 volts or mains electricity.

[0011] Further, the electromechanical control includes an electromechanical protection device, a power transformation, distribution and power transmission system, an online and metering detection device.

[0012] Further, a rubber plate is installed on the water energy tank to block the leakage at the arc joint section of the hydraulic mechanical wheel.

[0013] In the technical solution of the present invention, the water wheel shaft is parallel to the ground and higher than the ground; the involved power generation equipment is arranged on the same reinforced concrete foundation platform; the high-lift water pump is a centrifugal pump driven by a water pump motor, the best lift ≥25m, and the water flow is about 5000m 3 / h; the water storage tank is arranged at the lower end of the water wheel blades of the hydraulic mechanical wheel, and its water storage capacity ≥200m3 ; Embedded fixing devices and water turbine shaft bearing housings on the platform; Bearings or bearing bushes are installed on the water turbine shaft in the bearing box; Under the action of mechanical energy on the shaft of the hydraulic machinery wheel, the hydraulic machinery wheel and the water turbine blades rotate in the semi-closed water energy tank. The water turbine blades and the water turbine steel ring body form a water-receiving angle of less than 75 degrees upward; To ensure the accurate relative position between the semi-closed water energy tank and the water turbine, an annular positioning water stop ring is installed inside the outer surface edge of the water turbine steel ring; Considering the self-load and water-receiving load of the semi-closed water energy tank, when a large-diameter water turbine is selected, with a weight of up to hundreds of tons, an independent reinforced concrete or steel section support frame should be adopted. The large-mass hydraulic machinery wheel has a fixed radius height and load mass to form potential energy, and makes a uniform circular motion to generate kinetic energy, forming huge mechanical energy and inertia; To ensure the maximum and stability of mechanical energy, the key is that when the water turbine blades on the hydraulic machinery wheel rotate clockwise to 0 degrees, there should be sufficient potential energy. When rotating to less than 60 degrees, the water turbine blades instantaneously prevent water from discharging, allowing water to do work and drive the water turbine to fall and then discharge; The best angle for the water turbine blades to instantaneously prevent water from discharging is less than 60 degrees; When the semi-closed water energy tank is at 0 degrees to 60 degrees, the contact section between the water energy tank and the hydraulic machinery wheel is arc-shaped, the outer side is a vertical plate, and the two sides are arc-shaped side plates to form a funnel-shaped water-receiving tank; When the water energy tank is at 60 degrees to less than 180 degrees, it is arc-shaped to match the hydraulic machinery wheel; In the section of 60 degrees to less than 180 degrees, several water turbine blades actually prevent the freely falling water in the flowing state from discharging at different angles. Utilizing the fluid characteristics, the water turbine blades hinder the acceleration of the water falling body. When the water falls and discharges in the semi-closed water energy tank, it will surely drive several water turbine blades in the water energy tank to fall together. The water turbine blades are welded on the outer surface of the water turbine steel ring, which will surely drive the hydraulic machinery wheel to rotate; The large-mass hydraulic machinery wheel has a fixed radius height and load mass to form potential energy, and makes a uniform circular motion to generate kinetic energy, forming huge mechanical energy and inertia to maintain the state of the mechanical wheel making a uniform circular motion, helping to store and convert energy; To achieve the purpose of driving the rotation of the shaft of the hydraulic machinery wheel.

[0014] In order to ensure the relative sealing between the water energy tank and the outer ring of the mechanical wheel and prevent water leakage, a rubber plate is installed on the edge of the outer ring of the mechanical wheel at the joint to block the leakage of the arc joint section with the hydraulic mechanical wheel; when the high-lift water pump continuously injects water into the semi-closed water energy tank to keep the hydraulic mechanical wheel rotating repeatedly, huge inertia and mechanical energy are formed; this mechanical energy is transmitted to the input port of the multi-functional gearbox, and the required power is provided for the operation of the generator by changing the torque and speed; the generated power is incorporated into the power supply network after passing through the electromechanical control system. The power energy problem of the generator is completely solved, providing a power source that is not affected by any natural environment and can generate power all day and at low cost. When a high-voltage generator is used to generate 10050 volt 50 Hz AC or 50 Hz AC from the city power grid, the system power generation is controlled by the electromechanical intelligent control and power generation metering control including the power generation system device, and the protection device; when the high-lift centrifugal pump continuously injects water into the semi-enclosed water energy tank, the motor power of the centrifugal pump can also be switched to the self-powered system to maintain the centrifugal pump, forming a repetitive cycle system of the static water power generation device. The static water power generation device provided by the invention of this application can be widely used in the generator sets of newly built megawatt-class small and medium-sized power stations to provide large power energy; it can also provide self-operated power for self-operated megawatt-class power units, ocean-going loan ships, smelters, high-energy-consuming factories, and town docks.
