[0032] Principle and use process of the utility model:

[0033] When it is needed to use, the water flow in the hole flows into the collecting pipeline 1, and then passes through the guide pipeline 2, wherein the filter screen 6 in the guide pipeline 2 filters the passing water flow, and when the filter screen 6 is filtered for a period of time, a large amount of sundries is accumulated on the surface of the filter screen 6, first, the staff member closes the collecting pipeline 1 to prevent the water flow from passing, and at this time, the height sensor 7 plays a role, when the sundries is accumulated to the limited height of the height sensor 7, the height sensor 7 transmits a signal to the control system one 38 and the control system two 45, since the power supply one 37 and the power supply two 44 respectively distribute power supply to the control system one 38 and the control system two 45, at this time, the control system two 45 controls the operation of the telescopic cylinder 43 first, the output end of the telescopic cylinder 43 makes the baffle 48 retract, the baffle 48 moves in the limiting groove 49, at this time, the mounting seat two 41 has a collecting space without the block of the baffle 48, at this time, the control system one 38 controls the operation of the multi-stage electric telescopic rod 32, the output end of the multi-stage electric telescopic rod 32 pushes out the pushing plate 34, and the fixed seat 33 is also driven to move by the output end, since the pushing plate 34 is stably moved under the action of the limiting block 35, and the pushing plate 34 pushes the sundries into the recess two 410 in the mounting seat two 41, and at this time, the cleaning roller 314 on the fixed seat 33 also moves, when the cleaning roller 314 moves to the inclined surface 39, at this time, the spring 312 plays a role, the cleaning roller 314 is not blocked, the sliding block 311 slides on the sliding column 310, and then the cleaning roller 314 is displaced to the filter screen 6, under the rotation of the cleaning roller 314, the clogged silt on the filter screen 6 is further cleaned, to ensure that the next drainage is smoothly performed, when the cleaning is completed, the multi-stage electric telescopic rod 32 makes the pushing plate 34 and the fixed seat 33 retract to the original position, and the telescopic cylinder 43 makes the baffle 48 move to the original position, without affecting the water flow from the guide pipeline 2 to drain out;

[0034] When the water flow in the hole flows into the collecting pipeline 1, the water flow passes through the filter screen 6 by relying on the gravity of the water flow itself, and finally reaches the stilling basin 5, the plurality of stilling blocks 51 in the stilling basin 5 give the water flow to be still, to reduce the impact force, and the pushing and cleaning assembly 3 and the collecting assembly 4 installed on both sides of the guide pipeline 2 are each equipped with an independent channel, so that the staff member can perform later maintenance and open the door two 46 to clean the sundries in the recess two 410, and the later sundry collection is facilitated.
