Firstly, an operator pushes the device to move above a well lid through a wheel 1, then pulls a sliding sleeve 17 to move left and right, the sliding sleeve 17 moves left and right to drive a second supporting rod 18 to move left and right, the second supporting rod 18 moves left and right to drive a deep device 19 to move left and right, when the deep device 19 moves left and right to be right above a water leakage hole of the well lid, the sliding sleeve 17 is stopped being pulled, a rod is put into a first groove 9, the rotating rod drives a rotating rod 8 to rotate forward, the rotating rod 8 rotates forward to drive a bevel gear 10 to rotate forward, the bevel gear 10 rotates forward to drive a threaded disc 11 to rotate backward, the threaded disc 11 rotates backward to drive a first screw 12 to rotate backward, a threaded sleeve 13 is driven to move downward by the first screw 12, the threaded sleeve 13 moves downward to drive an inner wall threaded pipe 14 to move downward, the inner wall threaded pipe 14 moves downward to drive a second mounting, the slide bar 16 moves downwards to drive the slide sleeve 17 to move downwards, the slide sleeve 17 moves downwards to be brought into the deep device 19 through the second support bar 18 to move downwards, the deep device 19 moves downwards to penetrate through a water leakage hole of the well cover, when the second installation block 15 moves downwards to be in contact with the installation pipe 5, the rotation of the bar is stopped, and the deep device 19 can be pushed to move downwards to be in an expansion state. In the same way, after going deep into device 19 and expandes completely, the bull stick drives 8 reversals of bull stick again, and then sliding sleeve 17 moves up and drives through second bracing piece 18 and go deep into device 19 and move up, go deep into device 19 and move up and block it with the well lid contact, go deep into device 19 and move up and mention the well lid, mention when suitable position when the well lid, the rotation stopping pole, take out the pole from first recess 9, can drive the well lid through this device of wheel 1 promotion and remove to the next door, the staff can get into and clear up in the sewer. With the same principle, rubbish clean up back in the sewer, and the staff comes out the back, can promote this device and remove the well lid directly over the sewer, put into first recess 9 with the pole once more and drive bull stick 8 corotation, and then go deep into device 19 downstream and drive well lid downstream lid and return to on the sewer, the rotation stopping pole, 19 recovery to the normal position are deepened in the pulling, it loosens the well lid to go deep into device 19, can the rotation pole reversal, and then go deep into device 19 upward movement and resume to the normal position, the rotation stopping pole, take out the pole in first recess 9, promote this device removal and mention next well lid.

When an operator rotates the rod to drive the rotating rod 8 to rotate forwards, the sliding sleeve 17 drives the deep penetration block 199 to move downwards through the second support rod 18, the deep penetration block 199 moves downwards to pass through a water leakage hole of the well cover to move to a proper position, the rotating rod is stopped, the second pull rod 1914 is pushed to move downwards, the second pull rod 1914 moves downwards to drive the first pull rod 1913 to move downwards, the first pull rod 1913 moves downwards to drive the annular plate 1911 to move downwards through the connecting frame 1912, the annular plate 1911 moves downwards to drive the vertical slider 192 to move downwards through the third connecting rod 1910, the vertical slider 192 moves downwards to drive the second connecting rod 195 to move downwards through the first connecting rod 194, the second connecting rod 195 moves downwards to drive the rolling shaft 197 to move downwards, the rolling shaft 197 moves downwards to drive the word hole rod 196 to swing downwards, the word hole rod 196 swings downwards to be in a horizontal state, and when the word hole rod 196 is blocked by the blocking block 198, the second pull rod 1914 stops being pushed, namely, the rotatable rod drives the rotating rod 8 to rotate reversely, and then the penetration block 199 moves upwards to drive the linear hole rod 196 to move upwards, and the linear hole rod 196 moves upwards to contact with the well lid to lift the well lid to be separated from the sewer. After rubbish in the sewer is cleaned up, the well lid can be covered to the sewer, the second pull rod 1914 is pulled to move upwards, the second connecting rod 195 further moves upwards to drive the slotted hole rod 196 to swing upwards through the rolling shaft 197 to return to the original position, the second pull rod 1914 is stopped being pulled, and the rotating rod can rotate reversely with the rotating rod 8, so that the deep block 199 moves upwards to be separated from the water leakage hole of the well lid.

When the sliding sleeve 17 moves left and right and drives the deep block 199 to move right above the water leakage hole of the well cover through the second support rod 18, the second screw 24 can be twisted to rotate reversely, the second screw 24 rotates reversely and moves upwards through the nut 23, the second screw 24 moves upwards and is inserted into the second groove 25, the twisting of the second screw 24 is stopped, the second screw 24 is matched with the second groove 25 to fix the second mounting plate 20, and then the sliding sleeve 17 is fixed. When the well lid is returned to the sewer, the second screw rod 24 can be twisted to rotate forwards, the second screw rod 24 rotates forwards and moves downwards through the nut 23, the second screw rod 24 moves downwards to be separated from the second groove 25, the sliding sleeve 17 is loosened, and the second screw rod 24 stops being twisted. So, can prevent that the sliding sleeve 17 from removing at will and influencing mentioning of well lid.

When the device moves over the well lid, and the deep block 199 moves over the water leakage hole of the well lid, the pressing plate 27 can be pulled to swing downwards, the pressing plate 27 swings downwards to drive the fifth connecting rod 30 to swing downwards through the annular sliding block 29, the fifth connecting rod 30 swings downwards to be clamped into the first groove 9, the holding rod 31 can be pulled to rotate forwards, the holding rod 31 rotates forwards to drive the fifth connecting rod 30 to rotate forwards, the fifth connecting rod 30 rotates forwards to drive the rotating rod 8 to rotate forwards, the deep block 199 is driven to pass through the water leakage hole of the well lid to move to a proper position, the holding rod 31 stops being pulled to rotate forwards, the second holding rod 1914 can be pushed to move downwards to enable the first hole rod 196 to swing downwards to be in a horizontal state, the holding rod 31 is pulled to rotate backwards, the first hole rod 196 moves upwards to lift the well lid, and the holding rod 31 stops being pulled to rotate backwards. After rubbish in the sewer is cleaned up, and when the well lid moves to the position right above the sewer, the well lid can be returned to the sewer according to the above operation, when the rotating rod 8 does not need to be rotated, the pressing plate 27 is pulled to swing upwards, the pressing plate 27 swings upwards to drive the fifth connecting rod 30 to swing upwards through the annular sliding block 29 to be separated from the first groove 9, the retaining ring 32 can be hung on the hook 33, and the retaining ring 32 is hung on the hook 33 to fix the pressing plate 27. Therefore, the rotating rod 8 is more convenient for the operator to rotate.

When the operator pushes the second pulling rod 1914 to move, the hand of the operator contacts the rubber sleeve 34, and the rubber sleeve 34 increases the friction force with the hand, so that the operator can move the second pulling rod 1914 more stably.
