the settled sand cleaning module is configured to obtain a drill chip height value monitored by a settled sand sensor, control an electric control valve at a discharge port of the circulation tank to be opened after the height value exceeds a first preset height, and start a liquid supply pump to supply liquid to the rotary spray gun after the opening time of the electric control valve exceeds a time preset value;
and the sand setting cleaning closing module is configured to continuously monitor the drill chip height value monitored by the sand setting sensor, and close the liquid supply pump and close the electric control valve at the discharge outlet of the circulating tank when the drill chip height value is lower than a second preset height.
6. The recycling tank of claim 5, further comprising:
and the sand setting sensing alarm module is configured to acquire the drilling cutting height value monitored by the sand setting sensor and start the audible and visual alarm to give an alarm after the height value exceeds a preset first height.
7. The recycling tank of claim 5, further comprising:
and the rotary spray gun control module is configured to control a micro servo motor at the head of the rotary spray gun to drive the rotating angle of the gun head of the rotary spray gun.
8. An automatic induction cleaning method for a drilling fluid circulation tank, which is used for the circulation tank of any one of claims 1 to 4, and is characterized by comprising the following steps:
monitoring the height of drill cuttings accumulated at the bottom of the circulating tank by using a sand setting sensor;
an electric control valve at the outlet is opened, and a liquid supply pump is started to supply liquid to the rotary spray gun after the opening time of the electric control valve exceeds a preset time value;
and continuously monitoring the drilling cutting height value monitored by the sand setting sensor, and closing the liquid supply pump and closing the electric control valve at the discharge outlet of the circulating tank when the drilling cutting height value is lower than a second preset height.
9. The method of claim 8, further comprising:
and acquiring the height value of the drill cuttings monitored by the sand setting sensor, and starting an audible and visual alarm to give an alarm after the height value exceeds a preset first height.
10. The method of claim 8, further comprising:
and a miniature servo motor for controlling the head of the rotary spray gun drives the rotating angle of the gun head of the rotary spray gun.
