[0063] Working principle of the present invention:

[0064] When in use, under normal weather conditions, the movable cover 3 is closed and flush with the manhole cover 2 to meet daily drainage needs. Water flows into the well body 1 through the manhole cover 2, and is initially filtered through the inclined filter plate 10. Larger particles of impurities are intercepted on the inclined filter plate 10 and introduced into the collecting barrel 4. At this time, the lifting block 8 is located at the upper end of the threaded section 701 and is separated from the threaded section 701. The staff can start the motor 601 as needed. At this time, the crushing blade 602 rotates to crush the garbage, the toothed disc 9 rotates and cooperates with the vibrating part to drive the inclined filter plate 10 to shake so that the garbage is quickly discharged, and the movable cover 3 remains stationary. When in heavy rain, the motor 60 1 drives the rotating rod 7 to reverse, the lifting block 8 enters the threaded section 701 and moves downward along it, and drives the movable cover plate 3 to rotate downward through the support rod 801 and the slide rail 301, that is, the movable cover plate 3 is opened to increase the drainage area. When there is a lot of garbage, the lifting block 8 moves to the lower end of the threaded section 701 and disengages from the threaded section 701, the crushing blade 602 and the toothed disc 9 continue to rotate, the inclined filter plate 10 continues to vibrate and discharge, and the crushing blade 602 continues to crush the garbage, which effectively avoids the occurrence of garbage blockage and improves the drainage efficiency. After the heavy rain, the staff can regularly clean the collecting barrel 4 as needed, and the operation is flexible and convenient.
