[0021] Example 1
[0022] like Figure 1 As shown, this embodiment provides a novel hybrid power generation device, including a hydraulic system 1, a gravity generator set, and a substation 3. The hydraulic system 1 is connected to the mains power and is connected to the gravity generator set via a hydraulic motor 1. The gravity generator set includes a rotating component 21, a water tank 22, a water trough 23, and a generator 24. The main shaft of the rotating component 21 meshes with the hydraulic motor 1 via gears. The water tank 22 is located below the rotating component 21, and the water trough 23 is located above the rotating component 21. A water pump 4 is installed in the water tank 22 to pump water from the water tank 22 into the water trough 23. A branch pipe is installed on the pipe from the water pump 4 to the water trough 23, and a compressor 12 is installed on the branch pipe. The generator 24 is connected to both ends of the rotating component 21, and the rotating component 21 drives the generator 24 to generate electricity. The substation 3 connects the electricity generated by the generator 24 to the grid and finally transmits it back to the mains power.
[0023] Specifically, in the hydraulic system 1, the hydraulic motor provides the main force to the rotating component 21. The water pump 4 and the compressor 12 are connected to an external power source. The water pump 4 pumps water from the pool 22 into the tank 23. The tank 23 has an outlet at the bottom. The water in the tank 23 falls and impacts the rotating component 21, providing auxiliary power. To increase the impact force of the water, a branch pipe is provided on the pipe from the water pump 4 to the tank 23. The compressor 12 is installed on the branch pipe. The compressor 12 delivers compressed gas into the pipe to enhance the impact force of the water. The compressor 12 also provides auxiliary power. The water energy is converted into mechanical energy. The rotating component 21 drives the generator 24 to generate electricity, converting mechanical energy into electrical energy. Finally, the substation 3 connects the electrical energy generated by the generator 24 to the grid and transmits it back to the mains power.
[0024] Specifically, in order to control the movement speed of the rotating component 21, a speed reducer 5 is provided between the hydraulic motor 1 and the rotating component 21; the speed reducer 5 converts the high speed output by the hydraulic motor 1 into the low speed required by the equipment; while reducing the speed, it increases the output torque to meet the equipment's demand for greater power; through speed reduction adjustment, the inertia of the hydraulic motor 1 is matched with that of the load, improving system stability; reducing the impact and vibration on the hydraulic motor 1, and extending the equipment's lifespan.
[0025] In this embodiment, blades 6 are evenly distributed around the circumference of the rotating component 21, and blade grooves are provided between adjacent blades 6; the water flow impacts the blades 6 to generate an impact force, which drives the rotating component 21 to rotate and provides auxiliary power.
[0026] To further increase the impact force, a stamping impeller can be installed on the 21st circumference side of the rotating component.
[0027] In one embodiment, a pressure tank 11 is also provided between the water pump 4 and the compressor 12; the pressure tank 11 can compress the gas to a pressure higher than atmospheric pressure, store the gas in the tank, so that the gas can be stored in a smaller volume and released when needed; when the gas needs to be supplied to a certain device, the pressure tank 11 can stabilize the gas pressure and ensure the normal operation of the device; in this embodiment, the normal operation of the water pump 4 can be ensured.
[0028] It should be further explained that the hydraulic system includes power components, actuators, control components, auxiliary components, working medium, monitoring and protection components, etc. In this utility model, the power component is a hydraulic pump, which converts mechanical energy into hydraulic energy to provide the pressure and flow required by the system; the actuator is a hydraulic motor, which converts hydraulic energy into rotary motion, outputting torque and speed; the control components include a directional control valve, which controls the flow direction of the oil and determines the direction of movement of the actuator; a pressure control valve, which regulates the system pressure and prevents overload; and a flow control valve, which regulates the flow rate of the oil and controls the speed of the actuator; auxiliary components include an oil tank, oil filter, accumulator, pipelines and connectors, cooler and heater, etc.; the working medium is hydraulic oil; and the monitoring and protection components include pressure gauges, thermometers, level gauges and safety valves, etc.
[0029] Hydraulic power transmission has higher energy density than electric power transmission, is more flexible, has higher power and speed, is more resistant to impact and environment, and has a longer lifespan. Hydraulic motors have 10 times higher power density and 20 times higher response power ratio. They also have a great degree of freedom in terms of shape and space, and the adjustable transmission system is not limited by structural mechanics and structure.
[0030] Example 2
[0031] like Figure 2 As shown, this embodiment provides a novel hybrid power generation device, including an energy-saving module, a hydraulic system 1, a gravity generator set, and a substation 3. The energy-saving module includes a second hydraulic system 7, a second rotating component 8, and a second generator 9. The second hydraulic system 7 is connected to the mains power supply, and the second hydraulic motor in the second hydraulic system 7 is connected to the input end of the second rotating component 8. The power of the hydraulic pump in the second hydraulic system 7 is less than the power of the hydraulic pump in the first hydraulic system. The output end of the second rotating component 8 is connected to the second generator 9 to drive the second generator 9 to generate electricity. The second generator 9 is connected to the first hydraulic system to provide power to the first hydraulic system.
[0032] Hydraulic motor 1 in hydraulic system 1 is connected to gravity generator set. Gravity generator set includes rotating component 21, water tank 22, water trough 23 and generator 24. The main shaft of rotating component 21 meshes with hydraulic motor 1 through gear. Water tank 22 is located below rotating component 21 and water trough 23 is located above rotating component 21. Water pump 4 is installed in water tank 22 to pump water from water tank 22 to water trough 23. Branch pipe is installed on the pipe from water pump 4 to water trough 23, and compressor 12 is installed on the branch pipe. Generator 24 is connected to both ends of rotating component 21. Rotating component 21 drives generator 24 to generate electricity. Substation 3 connects the power generated by generator 24 to the grid and finally transmits it back to the mains power.
[0033] Specifically, in hydraulic system 27, hydraulic motor 2 drives rotating component 28 to convert hydraulic energy into mechanical energy. Rotating component 28 drives generator 29 to convert mechanical energy into electrical energy. The generated electrical energy provides power to hydraulic system 1. Since the power of the hydraulic pump in hydraulic system 1 is less than that of the hydraulic pump in hydraulic system 27, the power consumption of hydraulic system 27 per unit time is less than that of hydraulic system 1 per unit time, thus achieving the effect of energy saving.
[0034] Specifically, in the hydraulic system 1, the hydraulic motor provides the main force to the rotating component 21. The water pump 4 and the compressor 12 are connected to an external power source. The water pump 4 pumps water from the pool 22 into the tank 23. The tank 23 has an outlet at the bottom. The water in the tank 23 falls and impacts the rotating component 21, providing auxiliary power. To increase the impact force of the water, a branch pipe is provided on the pipe from the water pump 4 to the tank 23. The compressor 12 is installed on the branch pipe. The compressor 12 delivers compressed gas into the pipe to enhance the impact force of the water. The compressor 12 also provides auxiliary power. The water energy is converted into mechanical energy. The rotating component 21 drives the generator 24 to generate electricity, converting mechanical energy into electrical energy. Finally, the substation 3 connects the electrical energy generated by the generator 24 to the grid and transmits it back to the mains power.
[0035] To control the movement speed of the rotating component 21, a speed reducer 5 is provided between the hydraulic motor and the rotating component 21. The speed reducer 5 converts the high speed output by the hydraulic motor into the low speed required by the equipment. While reducing the speed, it increases the output torque to meet the equipment's demand for greater power. Through speed reduction adjustment, the hydraulic motor is matched with the inertia of the load, improving system stability. It also reduces the impact and vibration on the hydraulic motor, extending the equipment's lifespan.
[0036] In this embodiment, blades 6 are evenly distributed around the circumference of the rotating component 21, and blade grooves are provided between adjacent blades 6; the water flow impacts the blades 6 to generate an impact force, which drives the rotating component 21 to rotate and provides auxiliary power.
[0037] To further increase the impact force, a stamping impeller can be installed on the 21st circumference side of the rotating component.
[0038] In one embodiment, a pressure tank 11 is also provided between the water pump 4 and the compressor 12; the pressure tank 11 can compress the gas to a pressure higher than atmospheric pressure, store the gas in the tank, so that the gas can be stored in a smaller volume and released when needed; when the gas needs to be supplied to a certain device, the pressure tank 11 can stabilize the gas pressure and ensure the normal operation of the device; in this embodiment, the normal operation of the water pump 4 can be ensured.
[0039] Furthermore, in order to control the movement speed of the rotating component 8, a reducer 5 is provided between the hydraulic motor 2 and the rotating component 8; the reducer 5 converts the high speed output of the hydraulic motor 2 into the low speed required by the equipment; while reducing the speed, it increases the output torque to meet the equipment's demand for greater power; through speed reduction adjustment, the inertia of the hydraulic motor 2 is matched with that of the load, improving system stability; reducing the impact and vibration on the hydraulic motor 2, and extending the equipment's lifespan.
[0040] In an optional embodiment, the generator 2 9 is connected to the water pump 4 and the compressor 12 respectively, driving the water pump 4 and the compressor 12 to work; specifically, the water pump 4 and the compressor 12 are driven by the excess electrical energy in the generator 2 9, avoiding connection to an external power source and thus avoiding energy waste.
[0041] In an optional embodiment, an electrical cabinet 10 is further provided between the second generator 9 and the first hydraulic system 1, and the electrical cabinet 10 is used for voltage stabilization.
[0042] In addition, the novel hybrid power generation device of this utility model can also be equipped with a remote monitoring system to remotely monitor and manage the device via a network.
[0043] It should be further explained that the hydraulic system in this embodiment includes power components, actuators, control components, auxiliary components, working medium, monitoring and protection components, etc. In this utility model, the power component is a hydraulic pump, which converts mechanical energy into hydraulic energy to provide the pressure and flow required by the system; the actuator is a hydraulic motor, which converts hydraulic energy into rotational motion, outputting torque and speed; the control components include a directional control valve, which controls the flow direction of the oil and determines the direction of movement of the actuator; a pressure control valve, which regulates the system pressure and prevents overload; and a flow control valve, which regulates the flow rate of the oil and controls the speed of the actuator; auxiliary components include an oil tank, an oil filter, an accumulator, pipelines and connectors, a cooler and a heater, etc.; the working medium is hydraulic oil; and the monitoring and protection components include pressure gauges, thermometers, level gauges and safety valves, etc.
[0044] Hydraulic power transmission has higher energy density than electric power transmission, is more flexible, has higher power and speed, is more resistant to impact and environment, and has a longer lifespan. Hydraulic motors have 10 times higher power density and 20 times higher response power ratio. They also have a great degree of freedom in terms of shape and space, and the adjustable transmission system is not limited by structural mechanics and structure.
[0045] This invention discloses a novel hybrid power generation device that follows the law of conservation of energy. It gathers hydraulic energy, water energy, compressed air, and inertial force on a rotating component 21, converting various forms of energy into mechanical energy. This mechanical energy is then converted into electrical energy by a generator 9. The law of conservation of energy is a fundamental physical principle that states that in a closed system, energy cannot be created or destroyed, but can only be transformed from one form to another, while the total energy remains constant. If we assume that all the energy in a system can be superimposed, then at any given point in time, the total energy of the system will be the sum of all individual energy components. In this case, if we can accurately measure and track each individual energy component, and all energy conversions are reversible, then the law of conservation of energy still holds.
[0046] However, it is important to note that in practical applications, energy often does not exist in isolated forms, but rather interacts and intertwines with other physical quantities. Therefore, in practical applications, we usually need more complex physical models and theories to describe and analyze energy conversion and conservation.
[0047] In summary, while energy superposition is an interesting mathematical concept, in the actual physical world, we are more concerned with energy conversion and conservation, and how to verify these principles through experiments and measurements.
[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
