A manhole cover automatic locking structure and its application method

Abstract

The invention discloses a manhole cover automatic lock structure and its use method, and relates to the technical field of manhole cover locks. A manhole cover automatic lock structure includes a mounting seat, a well cover, a support mechanism and a locking mechanism, and the mounting seat is fixedly installed on the wellhead At the same time, the end of the manhole cover away from the locking rod is rotated and installed on the top of the mounting seat through a fixed shaft. At this time, the locking rod at the bottom of the manhole cover is fastened into the locking mechanism inside the mounting seat to complete the locking of the manhole cover. Tight, when someone is trapped in the sewer, the trapped person pulls the rotating shaft to move horizontally, so that the gear meshes on the outer wall of the rack, and turning the rocker drives the auxiliary block to move downward, thereby driving the locking sleeve to move downward, thus Open the well cover to facilitate the escape of the trapped people from the sewer. After the escape is completed, squeeze the rotating shaft into the cavity to make the gear detach from the surface of the rack. At this time, press the well cover on the surface of the mounting seat to complete the lock on the well cover. Tight, the use of manhole covers 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 ...

AI Technical Summary

Problems solved by technology

Due to the generally deep design of the inspection well, coupled with the noise of the surrounding vehicles and construction, when the manhole cover is closed, it is difficult for the people on the ground to notice the shouting of the underground personnel, thus causing the underground personnel to be trapped

Due to the small and dark underground space and the thin air, the trapped people are under enormous physical and psychological pressure. If they do not escape in time, the probability of survival is extremely low. Therefore, it is necessary to design an escape device for the smart manhole cover. Less
