[0024] Please refer to Figure 1 , the embodiment of the present application provides an ROV water and electricity supply system, which can automatically control the power supply and water supply to the underwater cleaning ROV device according to set parameters to ensure the stability of the power supply and water supply.

[0025] Among them, the system includes a power supply module, a PLC control module 4, a human-machine interaction module 5, and a water supply module. The PLC control module 4 consists of a PLC host and its communication module and various electrical components, and can receive data from each sensor and execute program control of the power supply module, the human-machine interaction module 5, the water supply module, etc. The power supply module is respectively connected to the PLC control module 4 and the ROV device 9 to supply power to the ROV device 9.

[0026] Specifically, the power supply module includes a power generation unit 100 and an overvoltage circuit protection unit 200. Among them, the power generation unit 100 is respectively connected to the PLC control module 4 and the ROV device 9. The power generation unit 100 outputs direct current and provides power supply for the ROV device 9.

The water storage unit 300 and the water pumping unit 400 are respectively connected to the PLC control module 4, and the water pumping unit 400 is connected to the water storage unit 300 and the ROV device. The water pumping unit 400 pumps water from an external water source and stores it in the water storage unit 300 so that the water storage unit 300 can supply water to the ROV device 9 according to actual needs.

When the overvoltage circuit protection unit 200 detects an abnormal voltage in the power supply circuit of the power generation unit 100, it can automatically step down the circuit, further improving the stability of the power supply of the system.

[0028] In a specific embodiment, the overvoltage circuit protection unit 200 includes a voltage detection module 6, a relay 7, and a braking resistor 8 connected in sequence. Among them, the current input end of the voltage detection module 6 is connected to the power supply circuit, and the current output end of the braking resistor 8 is connected to the power supply circuit. When the voltage detection module 6 detects an abnormal voltage (i.e., overvoltage) in the power supply circuit, it outputs a signal to the relay 7.

[0031] Here, the PLC control module 4 controls the start or stop of the inverter 12 and the electric pump 13, and adjusts the speed of the electric pump 13 by controlling the output frequency of the inverter 12. The electric pump 13 pumps water from the water storage unit 300 and pressurizes it for supply to the valve group 11. The first pressure sensor 10 is used to detect the outlet pressure of the valve group 11, send the current pressure data to the PLC control module 4, and the PLC control module 4 controls the output frequency of the inverter 12 according to the pressure data to control the motor speed of the electric pump 13, thereby controlling the supply water pressure and flow rate.

[0032] Further, the valve group 11 includes a supply valve and a pressure relief valve. The supply valve is connected to the pipeline between the electric pump 13 and the ROV device 9.

[0033] In a specific embodiment, the water storage unit 300 includes a water pump 18, a water storage tank 15, and a liquid level sensor 14. Among them, the PLC control module 4 is connected to the water pump 18 to control the opening or stopping of the water pump 18.

The self-cleaning unit is connected to the water storage unit 300 and the filter 17, and the self-cleaning unit transmits a signal to the PLC control module 4. When the self-cleaning unit detects that the pressure of the water supply pipeline rises abnormally, it is determined that the self-cleaning unit needs to be drained and cleaned, and water is pumped from the water storage unit 300 for self-cleaning.

[0035] Specifically, the self-cleaning unit includes a high-pressure pump, a filter 17, a filter valve 16, a second pressure sensor 19, and a drain valve 20.

[0036] Here, the water pump 18 pumps seawater into the filter 17 to filter out particulate impurities. When the second pressure sensor 19 detects that the pressure of the water supply pipeline rises abnormally, it is determined that the filter 17 is blocked and needs to be drained and cleaned; at this time, the filter valve 16 is closed to cut off the water supply from the filter 17 to the water storage tank 15. When performing self-cleaning, the drain valve 20 is opened, and the high-pressure pump is started by the PLC control module 4 to pump water from the water storage tank 15 and flush the filter 17, and the sewage is discharged to the external environment through the drain valve 20.
