Description

Technical Field

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

[0002] The existing power generation modes are nuclear energy, natural reservoir water storage, thermal power, wind power, and solar power generation. These energy sources are used to drive the generator to rotate and cut the magnetic lines to generate electricity. However, there are defects in these methods of power generation. For example, nuclear power generation is subject to policy, technology, 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, which affects the power generation 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 used, it must be converted into alternating current through an inverter before it can be connected to the Internet. In particular, it is necessary to store the direct current and then convert it into alternating current through an inverter to connect to the Internet, which requires a huge storage device, with high investment costs and low economic benefits. Therefore, it is urgent to develop a double-layer hydraulic mechanical wheel hydrostatic power generation system that is not affected by any natural environment and generates electricity all day long.

[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 double-layer hydraulic mechanical wheel hydrostatic power generation system technology. Summary of the invention

[0004] The purpose of the present invention is to provide a double-layer hydraulic mechanical wheel hydrostatic power generation system to generate electricity; using a centrifugal water pump, the static water is lifted to the top of the hydraulic mechanical wheel and discharged into a semi-enclosed water energy tank, and mechanical energy is formed under the action of the kinetic energy and potential energy of the discharged water in the water energy tank; the water wheel rotates under the action of the external force of mechanical energy, and performs uniform circular motion to generate huge inertia to keep the mechanical wheel in a state of uniform circular motion, helping to store and transform energy; the potential energy of the large-mass water wheel is the fixed diameter height of the water wheel, and its water wheel kinetic energy speed is uniform, forming huge fixed mechanical energy; the static water is lifted to the high level for work and reused, and the static water after work is transported to the low-level hydraulic mechanical wheel, driving the low-level water wheel to rotate and also generate huge mechanical energy. The hydraulic mechanical wheel axle is transmitted to the input port of the multi-functional gearbox, and the torque and speed are changed by the gearbox to provide the generator with the speed and power required for power generation; the power generation 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. To solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A double-layer hydraulic machinery wheel hydrostatic power generation system of the present invention is characterized in that the double-layer hydraulic machinery wheel hydrostatic power generation system is composed of a large-flow water pump, a water storage tank, a double-layer hydraulic machinery wheel, a water energy tank, a water energy tank structure framework, a secondary water storage tank device, an electromechanical system, a high-level and a low-level structural platform; the large-flow water pump is a centrifugal pump driven by an electric motor to inject water into the high-level water energy tank; the water storage tank is arranged at the bottom end of the hydraulic machinery wheel; the hydraulic machinery wheel includes a double-layer arrangement of high-level and low-level; both the double-layer hydraulic machinery wheels include a water wheel shaft, a water wheel steel ring body, a water wheel steel ring body support frame, and water wheel blades; steel plate water wheel blades are welded on the outer surface of the water wheel steel ring body, and the water wheel blades form a water-receiving angle of <75 degrees on the water wheel steel ring body; the water energy tank is a curved vertical water energy tank, the upper end of which is funnel-shaped and the main body is a curved groove; the curved groove is arc-matched with the joint section of the water wheel steel ring body; the water energy tank structure framework is used for the double-layer water energy tank, and the double-layer water wheels are arranged in parallel and offset; the secondary water storage tank device is provided with a discharge port and a funnel-shaped water collecting basin from the front or side of the lower end of the high-level water energy tank, and the bottom of the water collecting basin is connected to a secondary water pipeline leading to the lower-level hydraulic machinery wheel; the secondary water pipeline is connected to the lower-level water energy tank; the water wheel shafts and the electromechanical system of the high-level or low-level are respectively installed on the high-level or low-level structural platforms.

[0006] Furthermore, the large-flow water pump has a switching function of injecting water separately into the low-level water power machinery wheel and uses a hydraulic ram pump for energy replenishment.

[0007] Furthermore, the length of the blades on the hydraulic machinery wheel rotating in the water energy tank is <1000 mm.

[0008] Furthermore, for the curved vertical water energy tank, the water storage capacity of the funnel-shaped part is 4 cubic meters to ensure sufficient mass to generate mechanical energy.

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

[0010] Furthermore, rubber plates are installed on the water energy tank to block the leakage at the arc joint section of the hydraulic machinery wheel.

[0011] Furthermore, the double-layer hydraulic machinery wheels are arranged in parallel and the axial centers are offset by ≤1 / 2 of the water wheel diameter, and the high-level and low-level structural platforms are arranged in the same or opposite directions.

[0012] Furthermore, the discharge port provided on the front or side of the lower end of the high-level water energy tank is located at 150 degrees when the water wheel rotates clockwise.

[0013] In the technical solution of the present invention, the water turbine 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 large-flow water pump is a centrifugal pump driven by a pump motor, with an optimal head ≥ 25m and a water flow rate of about 5000m 3 / h; the water storage tank is arranged at the lower end of the hydraulic mechanical wheel blade, and its water storage capacity ≥ 200m 3 ; fixing devices and water turbine shaft bearing housings are pre-buried on the platform; bearings or bushings are installed on the water turbine shaft in the bearing box; under the action of mechanical energy, the hydraulic mechanical wheel and the water turbine blades rotate in the semi-closed water energy tank, and the water turbine blades and the water turbine steel ring body form a water-receiving angle of < 75 degrees upward; in order to ensure the accurate relative position and water stoppage 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 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 support frame should be adopted. The large-mass hydraulic mechanical 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 uniform circular motion of the mechanical energy, helping to store and convert energy; in order to ensure the maximum and stability of the mechanical energy, the key is that when the water turbine blades on the hydraulic mechanical wheel rotate clockwise to 0 degrees, there should be sufficient potential energy, and when rotating to < 60 degrees, the water turbine blades instantaneously prevent the water from discharging, allowing the water to do work and then discharging after driving the water turbine to fall; the optimal angle for the water turbine blades to instantaneously prevent the water from discharging is < 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 mechanical wheel is arc-shaped, the outer side is a vertical plate, and the two sides are arc-shaped side plates, and the four sides form a funnel-shaped water tank to hold water; when the water energy tank is at 60 degrees to < 150 degrees, it is arc-shaped to match the hydraulic mechanical wheel; in the section from 0 degrees to < 150 degrees, several water turbine blades actually prevent the flowing water from freely falling at different angles. Utilizing the fluid characteristics, the water turbine blades hinder the acceleration of the fluid 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 mechanical wheel to rotate; the large-mass hydraulic mechanical 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 uniform circular motion of the mechanical wheel, helping to store and convert energy; the static water is lifted to a high level to do work and then reused. The static water after doing work is transported to the lower-level hydraulic mechanical wheel to drive the lower-level water turbine to rotate, and the same huge mechanical energy is generated. The purpose of driving the double-layer hydraulic mechanical wheel shaft to rotate for static water power generation is achieved.

[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 a large-flow 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 and inertia keep the mechanical energy in a state of uniform circular motion, help store and convert energy to the input port of the multi-functional gearbox, and provide the required power 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. It completely solves the power energy problem of the generator and provides a power source that is not affected by any natural environment and can generate power all-weather 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-generating system to keep the centrifugal pump working, forming a double-layer hydraulic mechanical wheel hydrostatic power generation system circulation system. The reusable hydrostatic 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-generated power for self-operated megawatt-class power units, ocean-going loan ships, smelters, high-energy-consuming factories, and town docks.

Embodiment 2

[0023] As Figure 2 Figure 3 Figure 4 shown, this embodiment Figure 2 Figure 3 Figure 4 is used to illustrate the structure and function of the outer ring of the water wheel steel ring and the water wheel groove: The hydraulic 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 formed and the work done by using the resistance of the water fluid, 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 water wheel blade 34 forms an upward water-holding angle 36 with the water wheel steel ring body 33, and the best angle is 60 degrees; The water pump lifts the static water to the top of the semi-closed water energy tank 1; The water wheel groove on the working side of the hydraulic mechanical wheel is the part from 0 degrees to 60 degrees at the upper part, and its shape is an arc-shaped funnel-shaped water injection bin 41.

[0024] Considering the self-load of the water energy tank, the water-holding load, and the outward expansion force of the water, when a large-diameter water wheel is selected, the weight reaches hundreds of tons; First, the installation and fixation of the water energy tank should be considered; The hydraulic mechanical wheel makes a uniform circular motion through the water energy tank, and water work needs to be blocked during the motion. The structural frame 44 should have sufficient fatigue resistance rigidity; It is advisable to use an independent reinforced concrete or steel structure frame 44, and fix the water energy tank 4 to the structural frame 44 with the water energy tank fixing rod 45; Although the water energy tank has an annular positioning water stop ring 35 for control, it involves overflow and the hydraulic mechanical wheel cannot bear the load, so the installation accuracy must be ensured; The secondary water storage tank device collects the static water discharged from the water energy tank after doing work at a high level and transports it to the top of the water energy tank 21 of the low-level hydraulic mechanical wheel.
