Abstract

The invention discloses a well lid automatic lock structure and a using method thereof, and relates to the technical field of well lid locks. The well lid automatic lock structure comprises a mountingseat, a well lid, a supporting mechanism and a locking mechanism, the mounting seat is fixedly mounted on the side wall of the top of a well mouth, meanwhile, the end, away from a lock rod, of the well lid is rotatably installed at the top of the a mounting seat through a fixed rotating shaft, the lock rod at the bottom of the well lid is buckled in the locking mechanism in the mounting seat at the moment, locking of the well lid is completed, when someone is trapped in a sewer, the trapped person pulls the rotating shaft to move horizontally, so that a gear meshes with the outer wall of a rack, a rocker is rotated to drive an auxiliary block to move downwards so as to drive a locking sleeve to move downwards, thus the well lid is opened, the trapped person can go out of the sewer conveniently, the rotating shaft is pressed into a cavity after getting rid of trapping, the gear is separated from the surface of the rack, and the well lid can be locked by pressing the well lid on the surface of the mounting seat at the moment, so that the use of the well lid is safer.

Description

technical field

[0001] The invention relates to the technical field of manhole cover locks, in particular to an automatic manhole cover lock structure and its application method. Background technique

[0002] With the development of modern cities, many electric power, communication, gas, rainwater and other inspection wells are equipped with electronically controlled smart manhole covers, which have functions such as underground environmental information monitoring, information uploading, and electronic locks. The advantages of electronic smart manhole covers over traditional manhole covers are obvious, but their potential safety hazards cannot be ignored. When the well cover is opened for underground inspection and maintenance, due to personnel negligence or irregular management, pedestrians enter the underground by mistake, or the maintenance personnel go down to the well for inspection but the ground staff do not find it. Locked, the end of maintenance work. Due to the ...
