[0002] Hydropower generation is a renewable energy generation method that converts the kinetic energy of water flow into electrical energy. Its basic principle is to use the gravitational potential energy or kinetic energy of water to drive a water turbine, which in turn drives a generator to generate electricity.

Specific implementation manner

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] The present invention provides a precise control system for electromagnetic high-pressure water hammer pulse electromagnetic energy in a hydropower station as Figure 1-8 shown, which includes a main pipeline 1. A pump body mechanism with a water hammer effect is provided at one end of the main pipeline 1, and a water inlet pipeline 4 is provided at the other end of the main pipeline 1.

[0038] Specifically, the pump body structure includes:

[0039] A one-way drainage valve 2, which is arranged at the end of the main pipeline 1 far from the water inlet pipeline 4;

[0040] An impact valve 3, which is arranged in the middle of the main pipeline 1.

[0041] Furthermore, a connecting elbow 101 is arranged between the main pipeline 1 and the one-way drainage valve 2. A drain pipe 201 is arranged at the bottom of the one-way drainage valve 2, and fixing seats 102 are arranged at the bottom ends of the main pipeline 1 and the connecting elbow 101.

[0042] It should be noted that this solution consists of the main pipeline 1, the one-way drainage valve 2, the impact valve 3, and the water inlet pipeline 4 to jointly form a water hammer pump structure. This pump body can pump water to a high place through the water hammer effect;

[0043] The water hammer effect refers to the phenomenon that when a fluid passes through a pipeline, due to a sudden change in flow velocity (such as the rapid closing of a valve or the start and stop of a pump), the pressure in the pipeline fluctuates violently instantaneously. This phenomenon will generate shock waves, resulting in an instantaneous increase in the pressure in the pipeline. By utilizing the change in water pressure and through the cooperation of the one-way drainage valve 2 and the impact valve 3, the water body is pumped to a high place.

[0044] It further includes:

[0045] An electromagnetic control mechanism is provided on the outer wall of the water inlet pipe 4. The electromagnetic control mechanism includes an electromagnetic component, a monitoring component, and a control component. The electromagnetic component is sleeved on the outer wall of the water inlet pipe 4. The monitoring component is provided on the outer wall of the water inlet pipe 4 and is located at one end close to the main pipe 1. The control component is provided on one side of the electromagnetic component. The control component is used to assist in controlling the electromagnetic energy of the electromagnetic component through the data of the monitoring component.

[0046] Specifically, the electromagnetic component includes:

[0047] A bearing pipe, which is sleeved on the outer wall of the water inlet pipe 4;

[0048] An electromagnetic induction coil 10, which is wound around and sleeved in the middle of the bearing pipe. Both ends of the electromagnetic induction coil 10 are used to connect to the control component.

[0049] Further, the bearing pipe includes:

[0050] A sleeve pipe 7, which is sleeved on the outer wall of the water inlet pipe 4;

[0051] A closed pipe 8, which is sleeved on the outer wall of the sleeve pipe 7. The electromagnetic induction coil 10 is sleeved between the outer wall of the sleeve pipe 7 and the inner wall of the closed pipe 8.

[0052] Circular grooves 801 are symmetrically formed on the outer wall of the sleeve pipe 7 and the inner wall of the closed pipe 8. The circular grooves 801 are used for winding the electromagnetic induction coil 10. Both ends of the joint between the sleeve pipe 7 and the closed pipe 8 are fixedly connected with closed rings 701.

[0053] It should be noted that the sleeve pipe 7 is fixedly sleeved with the water inlet pipe 4. Through the formation of the circular grooves 801, the electromagnetic induction coil 10 can be stably wound and sleeved. Through the setting of the electromagnetic induction coil 10, after it is powered on, an electromagnetic field is formed. By using the electromagnetic field to generate a driving force on the water flow, the effect of accelerating the water flow can be achieved. This method requires a power source and the electromagnetic induction coil 10. When powered on, a magnetic field will be generated around the electromagnetic induction coil 10, and the magnetic field will exert a force on the charged particles in the water flow, thereby promoting the accelerated flow of the water flow.

[0054] Specifically, the control component includes a control box 9. A control board 11 is arranged inside the control box 9. The electromagnetic induction coil 10 is electrically connected to the output end of the control board 11. The input end of the control board 11 is used to connect to the monitoring component.

[0055] Specifically, the monitoring components include a pressure transmitter 5 and a flowmeter 6. The detection ends of the pressure transmitter 5 and the flowmeter 6 are both inserted and connected into the water inlet pipe 4. The communication ends of the pressure transmitter 5 and the flowmeter 6 are electrically connected to the input end of the control board 11. An electromagnetic control unit is arranged in the control board 11. The pressure transmitter 5 and the flowmeter 6 respectively transmit pressure and flow data for the electromagnetic control unit to adjust the output power of the electromagnetic induction coil 10.

[0056] It should be noted that the pressure transmitter 5 and the flowmeter 6 are commonly used measuring instruments in industrial automation and process control. Among them, the pressure transmitter 5 is used to measure the pressure of liquids or gases and convert it into a standard electrical signal (usually 4 - 20 mA or 0 - 10 V) for subsequent monitoring and control; the flowmeter 6 is used to measure the flow rate of fluids (volume flow rate or mass flow rate) and convert its data into a readable signal.

[0057] Furthermore, the electromagnetic control unit consists of a control module 1101, a water pressure receiving module 1102, a water flow receiving module 1103, a power calculation module 1104, a pressure setting module 1105, and a power output module 1106;

[0058] The input end of the water pressure receiving module 1102 is electrically connected to the communication end of the pressure transmitter 5. The water pressure receiving module 1102 is used to receive the detection data of the pressure transmitter 5;

[0059] The input end of the water flow receiving module 1103 is electrically connected to the communication end of the flowmeter 6. The water flow receiving module 1103 is used to receive the detection data of the flowmeter 6;

[0060] The output end of the power output module 1106 is electrically connected to both ends of the electromagnetic induction coil 10. The power output module 1106 is used to output power to the electromagnetic induction coil 10.

[0061] The output ends of the water pressure receiving module 1102 and the water flow receiving module 1103 are electrically connected to the receiving end of the control module 1101. The pressure setting module 1105 is electrically connected to the control end of the control module 1101. The power output module 1106 is electrically connected to the output end of the control module 1101. The communication end of the power calculation module 1104 is electrically connected to the communication end of the control module 1101. The control module 1101 uses the data provided by the water pressure receiving module 1102 and the water flow receiving module 1103 to control the power calculation module 1104 to perform power calculation.

[0062] It should be noted that when controlling the power output of the electromagnetic induction coil 10, first, the water pressure receiving module 1102 and the water flow receiving module 1103 receive the water pressure and water flow data from the pressure transmitter 5 and the flow meter 6 respectively. This data is sent by the control module 1101 to the power calculation module 1104. After the power calculation module 1104 calculates the power data, it is transmitted back to the control module 1101. At this time, the control module 1101 controls the power of the electromagnetic induction coil 10 through the power output module 1106.

[0063] Among them, the calculation formula for the pressure change of the water flow in the water inlet pipe is expressed as:

[0064]

[0065] Among them, P 1 represents the pressure value set by the pressure setting module 1105, P 2 represents the pressure value detected by the pressure transmitter 5, v 1 represents the water flow velocity at the position where the control board 11 is located, v 2 represents the water flow velocity detected by the flow meter 6, h 1 represents the water height at the position where the control board 11 is located, h 2 represents the water height detected by the flow meter 6.

[0066] The relationship between the change in water pressure and current is expressed as:

[0067] I = k(P 2 - P 1 ) (2);

[0068] Among them, I represents the current, P 1 represents the pressure value set by the pressure setting module 1105, P 2 represents the pressure value detected by the pressure transmitter 5, and k represents the proportional relationship between the current and the change in water pressure.

[0069] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
