Repeatedly implementing SP 3 and SP 4 until the water supplementing of the water storage tank is completed;
SP 5 the water tank moisturizing is accomplished, utilizes control panel to close the water pump, first blowback control valve and second blowback control valve will the water suction tap takes out from the river and fixes to on the watering lorry.
6. The anti-blocking control method according to claim 5, characterized in that: the water pump is in a stop state in the initial state of the flushing and spraying back-flushing emptying mode, the water outlet control valves, the first back-flushing control valve, the second back-flushing control valve and the back-flushing pipe control valve are all in a cut-off state,
The flushing and spraying back-flushing emptying mode comprises the following steps,
SP 1 ,, utilizing the control panel to open each water outlet control valve and starting the water pump, so that water in the water storage tank is sprayed out through the water inlet and outlet pipe, the water outlet main pipe, each water outlet branch pipe, each water outlet control valve, each front flushing nozzle and each rear spraying nozzle in sequence, and flushing and spraying tasks are implemented;
After SP 2 , and the flushing and spraying tasks are completed, the water pump is turned off by using the control panel;
SP 3 ,, utilize control panel open first blowback control valve with blowback pipe control valve makes the interior high-pressure gas of high-pressure gas storage jar passes through the high-pressure blowback pipe, the water suction pipe gets into in the water outlet header pipe, and through in the water outlet header pipe to each water outlet branch pipe distributes, finally through each preceding washing mouth and each back spray nozzle blowout, in this process will water outlet header pipe with each water outlet branch pipe is carried out, empties above-mentioned pipeline to the phenomenon of icing the jam in the pipe appears in low temperature environment.
7. The anti-blocking control method according to claim 5 or 6, characterized in that: the high-pressure air storage tank is provided with a pressure sensor, the pressure sensor is connected to a vehicle-mounted computer of the sprinkler, the high-pressure air storage tank is communicated with a supplementary air pump through a pipeline, and a control end of the supplementary air pump is arranged on the control panel.
8. The anti-blocking control method according to claim 7, characterized in that: also comprises a gas supplementing mode for supplementing high-pressure gas into the high-pressure gas storage tank, comprising the following steps,
SP 1 ,,, presetting a lowest pressure value and a highest pressure value of the high-pressure air storage tank in the vehicle-mounted computer;
SP 2 ,,, the pressure sensor detects the actual pressure value of the high-pressure air storage tank in real time and transmits the actual pressure value into the vehicle-mounted computer, and the vehicle-mounted computer compares the actual pressure value with the lowest pressure value and the highest pressure value;
SP 3 ,,, when the actual pressure value is smaller than the lowest pressure value, the vehicle-mounted computer controls the air supplementing pump to be started, high-pressure air is supplemented into the high-pressure air storage tank until the actual pressure value is larger than the highest pressure value, and the vehicle-mounted computer controls the air supplementing pump to stop supplementing air.
