Description

Technical Field

[0001] The present invention relates to the technical field of clean energy power generation, and in particular to a hydrostatic energy and mechanical wheel combined power generation system. Background Art

[0002] Current power generation methods include nuclear energy, natural reservoir water storage, thermal power, wind power, and solar power. These energy sources drive generators, cutting magnetic lines of force to generate electricity. However, these methods all have drawbacks. For example, nuclear power generation is constrained by policies, technologies, and conditions; hydropower is limited by natural resources and environmental controls, making expansion difficult; thermal power generation consumes large amounts of coal, oil, or biomass, causing environmental pollution; wind power generation is affected by wind speed, affecting power generation and poor voltage stability; solar power generation has a short effective sunlight period and cannot generate power 24 / 7; and the direct current (DC) generated by solar power must be converted to alternating current (AC) through an inverter before it can be connected to the grid. Furthermore, the DC power must be stored and then converted back to AC through an inverter, requiring a large amount of storage equipment, resulting in high investment costs and low economic benefits. Therefore, it is urgent to develop a hydrostatic power generation system that combines hydrostatic power and mechanical wheels to generate power 24 / 7, unaffected by the natural environment.

[0003] For example, the inventor's application number is 202510396568.8, a multifunctional gearbox system using mechanical energy to generate electricity, and the application number is 202510237132.4, a mechanical energy device for generating electricity, which discloses a mechanical energy device for generating electricity, has played a good role in solving my country's energy problems and laid the foundation for the use of a combined hydrostatic energy and mechanical wheel power generation system. Summary of the Invention

[0004] The present invention aims to provide a hydrostatic energy and mechanical wheel combined power generation system for generating electricity. A centrifugal water pump is used to lift the hydrostatic water to the top of the mechanical wheel and discharge it into a semi-enclosed hydropower tank. The kinetic energy and potential energy of the discharged water in the hydropower tank generate mechanical energy. The water wheel rotates under the action of the external force of the mechanical energy, performing uniform circular motion, generating huge inertia to maintain the mechanical energy in a state of uniform circular motion, helping to store and convert energy. The potential energy of the large-mass water wheel is the fixed diameter height of the water wheel, and its kinetic energy speed is uniform, forming huge fixed mechanical energy. In order to control the rotation speed of the mechanical wheel and enhance the rotation of the mechanical wheel, the controlled energy-boosting motor power and speed are input into and synchronized with the multifunctional gearbox. The multifunctional gearbox converts the speed to <30 rpm and then controls the rotation of the mechanical wheel. The mechanical wheel axle is transmitted to the input port of the multifunctional gearbox, and after the torque and speed are changed by the gearbox, it provides the speed and power required for power generation to the generator. The generated energy is incorporated into the power supply network after passing through the electromechanical control system. It effectively solves the problem that the power source of generators is restricted by policies, energy and natural environmental conditions, optimizes the power source of existing power generation, and overcomes a series of defects of existing new energy power generation that is restricted by natural environmental conditions. In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] The present invention provides a combined hydrostatic energy and mechanical wheel power generation system, characterized in that the combined hydrostatic energy and mechanical wheel power generation system consists of a water supply device, a variable frequency speed control device, a mechanical wheel, a hydropower tank, a hydropower tank structural frame, an electromechanical device, and a structural platform; the water supply device is a water pump motor driving a centrifugal pump to lift the static water in the water storage tank to the hydropower tank to start the mechanical wheel; the variable frequency speed control device inputs the controlled energy-boosting motor power and speed into a multifunctional gearbox and synchronizes with it, and the multifunctional gearbox controls the rotation of the mechanical wheel after the speed is converted to <30 rpm: the mechanical wheel includes a water wheel shaft, A water wheel steel ring, a water wheel steel ring support frame, and water wheel blades; steel plate water wheel blades are welded on the outer surface of the water wheel steel ring, and the water wheel blades form a water filling angle of less than 75 degrees on the water wheel steel ring; the water energy trough is an arc-shaped vertical water energy trough, the top of which is funnel-shaped and the main body is an arc-shaped trough; the arc-shaped trough matches the arc of the water wheel steel ring joint section; the water energy trough structural frame is a reinforced concrete structure or a steel structure; the electromechanical device consists of a multifunctional gearbox, a generator, an energy-boosting motor, and a substation and distribution power transmission unit; the water wheel shaft, multifunctional gearbox, energy-boosting motor, and generator are installed on the structural platform.

[0006] Furthermore, the power supply of the water pump motor and the booster motor is switched to self-generation after the generator generates stable power to maintain the still water lifting and the operation of the booster motor.

[0007] Furthermore, the funnel-shaped portion of the arc-shaped vertical water energy tank has a water capacity of 4 cubic meters to ensure sufficient mass to generate mechanical energy.

[0008] Furthermore, the vertical arc-shaped water energy trough begins to be semi-closed when the mechanical wheel rotates clockwise to 0 degrees, and the rotation energizer has a rubber plate to block leakage from the arc-shaped joint section of the mechanical wheel.

[0009] In the technical solution of the present invention, the water wheel shaft is parallel to the ground and higher than the ground; the power generation equipment involved is set on the same reinforced concrete foundation platform; the large flow water pump is a centrifugal pump driven by a water pump motor, with an optimal head of ≥25m and a water flow of 5000m 3 / h; the water storage tank is located at the bottom of the mechanical wheel blade, and its water storage capacity is ≥200m 3; Pre-embedded fixing devices and water wheel shaft bearing housings on the platform; bearings or bushings on the water wheel shaft are placed in bearing boxes; under the action of mechanical energy, the mechanical wheel shaft and the water wheel blades rotate in the semi-enclosed water energy tank, and the water wheel blades and the water wheel steel ring form an upward water-filled angle of less than 75 degrees; in order to ensure the accurate relative position of the semi-enclosed water energy tank and the water wheel and to stop water, an annular positioning water stop ring is placed inside the outer surface edge of the water wheel steel ring; considering the water energy tank's own load and water load, when a large-diameter water wheel is selected, the weight can reach hundreds of tons, and it is appropriate to use an independent reinforced concrete or steel water energy tank support frame. The large-mass mechanical wheel has a fixed radius, height, and load mass to form potential energy, and performs uniform circular motion to generate kinetic energy, forming huge mechanical energy and inertia to keep the mechanical wheel in a state of uniform circular motion, helping to store and convert energy; in order to ensure the maximum and stability of mechanical energy, the key is that the water wheel blades on the mechanical wheel must have sufficient potential energy when they rotate clockwise to 0 degrees. When rotating to less than 60 degrees, the water wheel blades instantly prevent water from discharging, allowing the water to do work and drive the water wheel to fall and then discharge; the optimal angle for the water wheel blades to instantly prevent water from discharging is less than 60 degrees; when the semi-enclosed water energy tank is between 0 degrees and 60 degrees, the contact section between the water energy tank and the mechanical wheel is arc-shaped, with a vertical plate on the outside and arc-shaped side plates on both sides. The four sides form a funnel-shaped water trough to hold water; when the water energy trough is 60 degrees to less than 180 degrees, it is in an arc shape that matches the mechanical wheel; in the section of 0 degrees to less than 180 degrees, several water wheel blades actually prevent the free fall of flowing water at different angles. By utilizing the fluid characteristics, the water wheel blades hinder the acceleration of the falling fluid. When water falls and discharges in the semi-closed water energy trough, it will inevitably fall with several water wheel blades in the water energy trough. The water wheel blades are welded to the outer surface of the water wheel steel ring, which will inevitably drive the mechanical wheel to rotate; the large-mass mechanical wheel has a fixed radius height and load mass to form potential energy, and performs uniform circular motion to generate kinetic energy, forming huge mechanical energy and inertia, so as to achieve the purpose of driving the mechanical wheel axle to rotate. To ensure a seal between the water energy tank and the outer ring of the mechanical wheel and prevent water leakage, a rubber sheet is installed on the edge of the outer ring of the mechanical wheel at this joint to block any leakage at the arc-shaped joint with the mechanical wheel. A high-flow water pump continuously injects water into the semi-enclosed water energy tank to maintain the repetitive rotation of the mechanical wheel, generating mechanical energy. To use external energy to regulate the speed of the mechanical wheel and replenish its energy, the controlled power and speed of the energy-boosting motor are input into and synchronized with the multifunctional transmission. The multifunctional transmission speed is reduced to less than 30 rpm and then controls the speed of the mechanical wheel. The energy of the energy-boosting motor, after being converted into torque and reduced in speed by the transmission, acts on the mechanical wheel rotation, which is equivalent to the hydrostatic energy. The combined effect of the two generates a huge inertia to maintain the mechanical wheel in a state of uniform circular motion, helping to store and convert energy. The low-speed mechanical wheel shaft is transmitted to the input port of the multifunctional transmission, and by converting the low speed into high speed, it provides the power required for the operation of the generator. The generated energy is then integrated into the power supply network through the electromechanical control system.Completely solve the power energy problem of generators and provide a power source that is not affected by any natural environment and can generate electricity around the clock and at low cost. When a high-voltage generator is used to generate 10050V 50Hz AC or 50Hz AC from a mains electricity source, the system power generation is controlled by an electromechanical intelligent control and power generation metering control including a power generation system device, and a protection device; when a high-lift centrifugal pump continuously injects water into a semi-enclosed water energy tank, the motor power and the booster motor power supply that drive the centrifugal pump can be switched to a self-generating system to maintain the operation of the centrifugal pump and the booster motor, forming a cycle of a hydrostatic energy and mechanical wheel combined power generation system. The hydrostatic energy and mechanical wheel combined power generation system provided by the present invention can be widely used in the construction of new megawatt-class small and medium-sized power stations; it can also provide self-operated power for self-operated megawatt-class power units, ocean-going vessels, smelters, high-energy-consuming factories, and town docks.

[0017] like Figure 1 As shown, this embodiment Figure 1 The following is a system diagram of a hydrostatic energy and mechanical wheel combined power generation system: ①. Still water storage tank 1: It is located at the bottom of the area occupied by the mechanical wheel, which is generally halfway underground. The mechanical wheel tank is cast with reinforced concrete to form a mechanical wheel tank. The tank bottom is deep enough to store water and collect the discharged water and leaked water during the dispatching process. Its water storage capacity is ≥200m 3 ; ②. High flow water pump 2: The high flow water pump is a centrifugal pump driven by a water pump motor, with an optimal head of ≥25m and a water flow of 5000m 3 / h or so; ③. Mechanical wheel 3: Consists of the water wheel shaft, water wheel steel ring support frame, water wheel steel ring, and water wheel blades; the upward angle formed by the water wheel blades and the water wheel steel ring is less than 75 degrees; Function 1: When the mechanical wheel rotates clockwise from 0 to nearly 180 degrees, it helps to hold water and prevent water leakage, thereby reducing the resistance of the mechanical wheel to rotation in the water energy tank; air resistance is reduced when the rotation is from 180 to 360 degrees; ④. Water energy tank 4: Encloses the still water, enhances the utilization efficiency of the still water, and provides sufficient water energy to drive the mechanical wheel. ⑤. Multifunctional gearbox 5: It is a gearbox that matches the turbine shaft. After changing the torque and speed in the gearbox, it provides the required matching speed and power for the generator; ⑥. Generator 6: When a high voltage generator is used, it generates 10050V 50Hz AC power or 50Hz AC power; ⑦. Electromechanical control 8: Electromechanical intelligent control and power generation metering control including power generation system devices, and protection devices to control system power generation. ⑧.

Frequency conversion speed control device: In order to use external energy to regulate the speed of the mechanical wheel and supply energy to the mechanical wheel, the controlled power and speed of the energy-boosting motor are input into the multi-function gearbox and synchronized with it. The multi-function gearbox decelerates the speed to <30 rpm and then controls the speed of the mechanical wheel. The energy of the energy-boosting motor is converted into torque and decelerated by the gearbox, and then acts on the mechanical wheel rotation with the same hydrostatic energy, forming a combined effect of the two. Example 2

[0018] like Figure 2 Figure 3 Figure 4 As shown, this embodiment Figure 2 Figure 3 Figure 4 This is a schematic diagram of the structure of the outer ring of the water wheel steel ring and the water wheel groove: the water pump lifts still water to the top 1 of the mechanical wheel; the mechanical wheel is composed of a water wheel shaft 31, a support frame 32, a water wheel steel ring body 33, water wheel blades 34, and an annular positioning water stop ring 35; according to the technical requirements of the megawatt-class water wheel steel ring body 33, the potential energy generated and the work done by utilizing the resistance of the water fluid are used, the diameter of the water wheel steel ring body 33 is between 10m and 20m, and the width of the water wheel steel ring body 33 is between 1.5m and 2.5m; the upward water-filling angle 36 formed by the water wheel blades 34 and the water wheel steel ring body 33 is optimally 60 degrees; the water wheel groove on the working side of the mechanical wheel is the upper portion 0 to 60 degrees, and is shaped like a curved funnel-shaped water filling tank 41, and the portion 60 degrees to less than 180 degrees is a curved water energy tank 42; In order to prevent water from leaking out of the water energy tank, a rubber plate 43 is used to block the water on the side of the water energy tank; flat-top screws are used to fix it from the inside of the tank to the outside; the static water does work in the water energy tank, generating mechanical energy and inertia of the mechanical wheel; in order to control the operating speed of the mechanical wheel and maintain inertia to keep the mechanical wheel in a state of uniform circular motion, it helps to store and convert energy; external energy is used to regulate the speed of the mechanical wheel and supply energy to the mechanical wheel, and the controlled power and speed of the energy-boosting motor are input into the multi-functional gearbox and synchronized with it. The multi-functional gearbox speed is decelerated and converted into <30 rpm to control the speed of the mechanical wheel. The energy of the energy-boosting motor acts on the mechanical wheel rotation with the same speed as the static water energy after the torque is changed and decelerated by the gearbox. The two play a combined role and control the speed of the mechanical wheel at the same time. Taking into account the load of the water tank itself, the water load and the outward expansion force of the water, when a large-diameter water wheel is selected, the weight can reach hundreds of tons; first of all, the installation and fixation of the water tank must be considered; the mechanical wheel performs uniform circular motion through the water tank, and it also needs to seal the water and do work during the motion, so the structural frame 44 must have sufficient fatigue resistance; it is advisable to use an independent reinforced concrete or steel structure frame 44, and use the water tank fixing rod 45 to fasten the water tank to the structural frame 44; although the water tank is controlled by an annular positioning water stop ring 35, it involves overflow and the mechanical wheel cannot bear weight, so the installation accuracy must be ensured.
