means for providing a runoff recycling injection mechanism as claimed in claim 1;
step 1: if a mud water pump (14) is installed on the device of the runoff circulation injection mechanism, the control system module controls the mud water pump (14) to pump runoff liquid, controls the electric switch valve (21) and the electric cylinder (22) to be not actuated, keeps the second drainage pipeline (20) and the first drainage pipeline (23) closed, and pumps the runoff liquid into the water receiving funnel (25) through the mud water pump water pipeline (24); if the device of the runoff circulation injection mechanism is not provided with the mud pump (14), the control system module controls to close the electric switch valve (21), shut off the second drainage pipeline (20), control the electric cylinder (22) not to act and keep the first drainage pipeline (23) shut off;
step 2: when runoff sampling is started, the vertical servo motor (1) controls the vertical sliding module (3) to move on the vertical truss track (2) so as to drive the sliding module supporting rod (10) to move, the sliding module supporting rod (10) is connected with the annular calipers (4) and the photoelectric sensor (5), the annular calipers (4) are arranged on the telescopic pipe (27), the water injector (6) is arranged at the tail end of the telescopic pipe (27), the annular calipers (4) move downwards along with the downward movement of the sliding module supporting rod (10), so that the telescopic pipe (27) is extended, and the water injector (6) moves downwards to the bottom of the sampling cup (7) along with the extension of the telescopic pipe (27); after the photoelectric sensor (5) detects that the water reaches the bottom of the sampling cup (7), a signal is sent to the control system module, the control system module controls the vertical sliding module (3) to stop moving downwards and controls the water injector (6) to be opened for injecting water;
and step 3: the water injection time value is preset according to the actual situation, after the water injection time reaches the preset water injection time, the control system module controls the water injector (6) to be closed, and the vertical servo motor (1) controls the water injector (6) to be lifted to the initial position; meanwhile, the control system module controls the horizontal servo motor (18) to enable the horizontal sliding module (19) to move on the horizontal truss track (17), so that the liquid receiving frame (16) is driven to move to the position below the tail end of the water injector (6), and residual dripping runoff liquid existing at the tail end of the water injector (6) is collected; a collection time value is preset according to actual conditions, and after collection reaches the preset collection time, the controller controls the horizontal servo motor (18) to drive the liquid receiving frame (16) to return to an initial position;
and 4, step 4: when the water injector (6) returns to the initial position, the control system module controls the electric cylinder (22) to act, the first drainage pipeline (23) is conducted to discharge runoff liquid accumulated in the horizontal pipeline (11), and meanwhile, the control system module opens the electric switch valve (21) and conducts the second drainage pipeline (20) to discharge the residual runoff liquid; if the mud pump (14) is in work, the mud pump (14) is closed firstly, and after accumulated liquid in the water injection pipeline (11) is discharged, the electric switch valve (21) is closed, and the second water discharge pipeline (20) is closed; the controller controls the electric cylinder (22) to act to cut off the first drainage pipeline (23), if the muddy water pump (14) does not work, the electric switch valve (21) is kept open, so that the second drainage pipeline (20) is kept conducted, but the electric cylinder (22) still acts to cut off the first drainage pipeline (23);
and 5: after the photoelectric sensor (5) detects that the liquid level in the sampling cup (7) reaches a preset value and a preset standing time is passed, the photoelectric sensor (5) on the sliding module support frame (10) measures the liquid level height for multiple times, the final runoff liquid height is obtained by an averaging method preset by the control system module, and meanwhile, the electronic scale (8) works to measure the weight of the runoff liquid; then the electronic scale (8) transmits the volume and mass information of the runoff liquid collected this time to the control system, and the control system starts to calculate the silt content in the runoff liquid;
