The operation is simple, time-saving and labor-saving, and the work efficiency is improved, and the safety is high.

[0026] When the water washing well sampling is completed and the manhole cover needs to be closed, the first fixed rod 7 is controlled to release the limit on the sliding wheel 3, and then the pull rod 5 is pushed to the right, so that the electric telescopic rod 4 drives its upper part to move to the right and reset, and then the first fixed rod 7 is controlled to limit the sliding wheel 3, the electric telescopic rod 4 and its upper part to the mobile bracket 1 on the right side, and then the second fixed rod 10 is controlled to release the limit on the telescopic end of the electric telescopic rod 4, and then the electric telescopic rod 4 is controlled to extend until the manhole cover contacts and closes with the wellhead, and then the handle 162 is pulled downward to make the n-type rod 16 slide downward, and the n-type rod 16 drives the n-type push rod 161 to move downward, and the inclined surface of the n-type push rod 161 and the The contact effect of the inclined surface of the wedge 14 squeezes the wedge 14 on the same side to move toward the side close to each other, and the first elastic member 15 is stretched until the top of the wedge 14 releases the limit on the bottom of the manhole cover, and then the electric telescopic rod 4 is controlled to shorten until the n-type frame 41 is out of contact with the through hole of the manhole cover, and the handle 162 is pulled upward until the n-type rod 16 drives the n-type push rod 161 to reset upward, and the n-type push rod 161 is out of contact with the wedge 14. Under the elastic force of the first elastic member 15, the two wedges 14 on the same side are driven to move and reset to the side away from each other.
