the controller acquires a liquid level signal value of the first detection module 21 and a liquid level signal value of the second detection module 22, and acquires a first drainage indication value, a second drainage indication value, a first drainage threshold value and a second drainage threshold value.

The controller compares the liquid level signal value of the first detection module 21 with a first drainage indication value and a first drainage valve value, and compares the liquid level signal value of the second detection module 22 with a second drainage indication value and a second drainage threshold value;

when the liquid level signal value of the first detection module 21 is greater than the first drainage indication value, the controller sends a first drainage indication signal of the first detection module 21 to the display module;

when the liquid level signal value of the second detection module 22 is greater than the second drainage indication value, the controller sends a second drainage indication signal of the second detection module 22 to the display module;

when the liquid level signal value of the first detection module 21 is smaller than the first drainage threshold value and the liquid level signal of the second detection module 22 is larger than the second drainage threshold value, the controller sends a working signal to the water pump 61 to pump the sewage in the second sewage tank 41 into the first sewage tank 31;

when the liquid level signal value of the first detection module 21 is greater than the drainage threshold value, the controller sends a stop signal to the water pump 61 to stop pumping the sewage in the second sewage tank 41 into the first sewage tank 31.

The first and second discharge indication values are manually input or automatically measured according to the actual capacities of the first and second wastewater tanks 31 and 41. The first wastewater tank 31 mainly serves to store wastewater, and the first preset value may be set to be between two thirds and four fifths of the total volume of the first wastewater tank 31 in order to prevent wastewater from being excessively loaded and affecting the wastewater discharge from the second wastewater tank 41. The second wastewater tank 41 mainly serves to temporarily store wastewater, and the second preset value may be set to be between one third and one half of the total capacity of the second wastewater tank 41 in order to prevent excessive wastewater loading from affecting driving.

when the liquid level signal value of the first detection module 21 is lower than the first drainage threshold value or the liquid level signal value of the third detection module 23 is higher than the threshold value, the air pump 52 can be freely turned on or off.

The critical value is manually inputted or automatically measured according to the actual capacity of the reservoir tank 51 and the amount of water required to complete one time of cleaning of the tank 30. The reservoir 51 is primarily used for cleaning the tank 30, so that the threshold value may be determined as a ratio of the amount of water required to complete a single cleaning to the total volume of the reservoir 51, e.g., one fifth of the reservoir 51 is required to clean the tank 30, and at least one fifth of the threshold value is the reservoir 51 to ensure that the flow of water is sufficient to complete a single cleaning.

The locking signal sent by the controller means that the display module displays after receiving the locking signal, and displays that the air pump 52 is in a locking state, that is, the air pump 52 is in a state of being closed and unable to be opened, so as to avoid opening the air pump 52 when no water exists in the water storage tank 51. The controller is a plc controller, judges the real-time state and position of the liquid level by comparing the potential signal of the current equipotential signal of the detection module with the potential signal of the prompt value, the threshold value and the critical value, feeds the real-time state and position back to the display module (the display module can be a display screen or a display panel) for displaying and prompting, and automatically controls the water pump 61 and the air pump 52 according to the comparison result.

6. The cleaning and decontamination vehicle of claim 1, further comprising a suction pipe, wherein the suction pipe interface is mated with the first connector.

7. The cleaning and dirt extracting garbage truck as claimed in claim 1, further comprising a first filter screen and a second filter screen, wherein the first filter screen is disposed at the bottom of the water storage tank, and the second filter screen is disposed at the bottom of the second sewage tank.

8. The garbage truck for cleaning and pumping sewage as claimed in claim 1, wherein the bottom of the material taking device is arranged obliquely, the gradient is 0.5% -3%, and the sewage outlet is positioned at the bottom of the slope.

9. The liquid level control method for cleaning the sewage pumping garbage truck comprises the steps of any one of claims 1 to 8, and is characterized by comprising the following steps:

the controller acquires a first detection module liquid level signal value and a second detection module liquid level signal value, and acquires a first drainage indication value, a second drainage indication value, a first drainage threshold value and a second drainage threshold value;

the controller compares the liquid level signal value of the first detection module with a first drainage indication value and a first drainage valve value, and compares the liquid level signal value of the second detection module with a second drainage indication value and a second drainage threshold value;

when the liquid level signal value of the first detection module is greater than the first drainage indication value, the controller sends a first drainage indication signal of the first detection module to the display module;

when the liquid level signal value of the second detection module is greater than the second drainage prompt value, the controller sends a second drainage prompt signal of the second detection module to the display module;

when the liquid level signal value of the first detection module is smaller than a first drainage threshold value and the liquid level signal of the second detection module is larger than a second drainage threshold value, the controller sends a working signal to the water pump to pump sewage in the second sewage tank into the first sewage tank;

when the liquid level signal value of the first detection module is larger than the drainage threshold value, the controller sends a stop signal to the water pump to stop pumping the sewage in the second sewage tank into the first sewage tank.

10. The liquid level control method for cleaning the sewage pumping garbage truck according to claim 9, further comprising the following steps of detecting the liquid level signal value of the third detection module:

the controller acquires a liquid level signal value and a critical value of the third detection module;

the controller compares the liquid level signal values of the first detection module, the second detection module and the third detection module with a drainage indication value, a drainage threshold value and a critical value;

when the liquid level signal value of the first detection module is higher than a first drainage threshold value or the liquid level signal value of the third detection module is lower than a critical value, the control module sends a gas pump locking signal, and the gas pump is in a closed state;

when the liquid level signal value of the first detection module is lower than the first drainage threshold value or the liquid level signal value of the third detection module is higher than the critical value, the air pump can be freely opened or closed.
