[0030] Example 2

[0031] like Figure 2 As shown, this embodiment provides a new 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 hydraulic system 2 7, a rotating component 2 8 and a generator 2 9. The hydraulic system 2 7 is connected to the mains, and the hydraulic motor 2 in the hydraulic system 2 7 is connected to the input end of the rotating component 2 8. The power of the hydraulic pump in the hydraulic system 2 7 is less than the power of the hydraulic pump in the hydraulic system 1; the output end of the rotating component 2 8 is connected to the generator 2 9 to drive the generator 2 9 to generate electricity; the generator 2 9 is connected to the hydraulic system 1 to provide power for the hydraulic system 1.

[0032] The hydraulic motor 1 in the hydraulic system 1 is connected to the gravity generator set, which includes a rotating component 21, a water pool 22, a water tank 23 and a generator 24. The main shaft of the rotating component 21 is meshed with the hydraulic motor 1 through gears.

The generated electrical energy provides power for the hydraulic system 1. Since the power of the hydraulic pump in the hydraulic system 1 is less than the power of the hydraulic pump in the hydraulic system 27, the power consumption per unit time of the hydraulic system 27 is less than the power consumption per unit time of the hydraulic system 1, thereby achieving energy saving effect.

[0034] Specifically, the hydraulic motor 1 in the hydraulic system 1 provides the main power to the rotating component 21, the water pump 4 and the compressor 12 are connected to the external power supply, the water pump 4 pumps the water in the pool 22 into the water tank 23, and a water outlet is provided at the bottom of the water tank 23. The water in the water tank 23 falls and impacts the rotating component 21, providing auxiliary power. In order to increase the impact force of the water, a branch pipe is provided on the pipeline from the water pump 4 to the water tank 23, and a compressor 12 is provided on the branch pipe. The compressor 12 transports compressed gas into the pipeline 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, and the mechanical energy is converted into electrical energy. Finally, the substation 3 connects the electrical energy generated by the generator 24 to the grid and finally transports it back to the city power.

[0035] In order to control the movement speed of the rotating component 21, a reducer 5 is arranged between the hydraulic motor 1 and the rotating component 21; the reducer 5 converts the high speed output by the hydraulic motor 1 into the low speed required by the equipment; while reducing the speed, the output torque is increased to meet the equipment's demand for greater power; through deceleration adjustment, the inertia of the hydraulic motor 1 is matched with that of the load to improve the stability of the system; the impact and vibration of the hydraulic motor 1 are reduced to extend the life of the equipment.

[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 impact of water flow generates impact force on the blades 6, driving the rotating component 21 to rotate and providing auxiliary power.

[0037] In order to further increase the impact force, a stamping impeller can be arranged on the side of the rotating component 21.

[0038] In one of the embodiments, a pressurized tank 11 is further provided between the water pump 4 and the compressor 12; the pressurized tank 11 can compress the gas to a pressure higher than normal pressure and store the gas in the tank body, 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 pressurized tank 11 can stabilize the pressure of the gas to 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 2 8, a reducer 5 is arranged between the hydraulic motor 2 and the rotating component 2 8; the reducer 5 converts the high speed output by the hydraulic motor 2 into the low speed required by the equipment; while reducing the speed, the output torque is increased to meet the equipment's demand for greater power; through deceleration adjustment, the inertia of the hydraulic motor 2 is matched with that of the load to improve the stability of the system; the impact and vibration of the hydraulic motor 2 are reduced to extend the life of the equipment.

Specifically, the water pump 4 and the compressor 12 are driven by the excess electric energy in the generator 2 9, avoiding the connection of an external power supply to cause a waste of electric energy.

[0042] In addition, the novel hybrid power generation device of the present invention can also be provided with a remote monitoring system to remotely monitor and manage the device through a network.

[0043] It should be noted that the hydraulic system in this embodiment includes power elements, actuators, control elements, auxiliary elements, working media, monitoring and protection elements, etc., wherein, in the present invention, the power element is a hydraulic pump, which converts mechanical energy into hydraulic energy and provides the pressure and flow required by the system; the actuator is a hydraulic motor, which converts hydraulic energy into rotational motion and outputs torque and speed; the control element includes a directional control valve, which controls the flow direction of the oil and determines the movement direction of the actuator; the pressure control valve adjusts the system pressure to prevent overload; the flow control valve adjusts the oil flow and controls the speed of the actuator; the auxiliary elements include an oil tank, an oil filter, an accumulator, pipes and joints, a cooler and a heater, etc.; the working medium is hydraulic oil; the monitoring and protection elements include a pressure gauge, a thermometer, a level gauge and a safety valve, etc.

[0044] Hydraulic energy transmission has higher energy density than electric energy transmission, flexible transmission, high power, high speed power density, impact and environmental resistance, long life. The power density of hydraulic motor is 10 times higher, and the response base power ratio is 20 times higher. It also has great freedom in shape and space, and the adjustable transmission system is not restricted by structural mechanics and structure.

[0045] A new hybrid power generation device of the present invention follows the law of conservation of energy, collects hydraulic energy, water energy, and compressed air on a rotating component 21, converts various forms of energy into mechanical energy, and then converts mechanical energy into electrical energy through a generator 29; Energy superposition The law of conservation of energy is a basic physical principle, which states that in a closed system, energy cannot be created or destroyed, but can only be converted from one form to another, while the total energy remains unchanged. If we assume that all 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 should be noted that in practical applications, energy often does not exist in an isolated form, but interacts and interweaves 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 general, although energy superposition is an interesting mathematical concept, in the actual physical world, we are more concerned with the conversion and conservation of energy, and how to verify these principles through experiments and measurements.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
