Abstract

The invention discloses an automatic safety monitoring device for urban subway tunnels, which relates to the technical field of subway tunnel monitoring and includes a monitoring device main body, a driving chamber, a working chamber, a signal transmission device, a laser scanner, a side baffle, and a first arc slot, the first fixed bearing and the front movable baffle, the top of the main body of the monitoring equipment is provided with a drive chamber, the bottom of the drive chamber is provided with a working chamber, and the inner wall of the working chamber is provided with a signal transmission device , the bottom of the main body of the monitoring equipment is provided with a laser scanner. The invention avoids the situation that flying insects and particles collide with the laser scanner under the relative force, and at the same time, it can clean the dust on the surface of the laser scanner, improve the accuracy of the laser scanner, and reduce the impact of the collision on the laser scanner. The resulting impact has a protective effect on the laser scanner, improves the stability of the device when it is working, and also improves the service life of the device.

Description

technical field [0001] The invention relates to the technical field of subway tunnel monitoring, in particular to an automatic safety monitoring device for urban subway tunnels. Background technique [0002] The subway is a fast, large-capacity, electric traction rail transit built in the city. The trains run on fully enclosed lines. The lines located in the central urban area are basically set up in underground tunnels, and the lines outside the central urban area are generally set up on viaducts or on the ground. The subway covers all kinds of underground and above-ground road rights in urban areas. , high-density, high-capacity urban rail transit system. The structure of the tunnel includes two parts, the main building and the auxiliary equipment. The main building is composed of the tunnel body and the tunnel door. The auxiliary equipment includes car avoidance tunnels, fire-fighting facilities, emergency communication and waterproof and drainage facilities. The long t...
