Abstract

The invention discloses urban subway tunnel automatic safety monitoring equipment, and relates to the technical field of subway tunnel monitoring. The equipment comprises a monitoring equipment body, a driving chamber, a working chamber, a signal transmission device, a laser scanner, a side baffle plate, a first arc-shaped groove, a first fixed bearing and a front movable baffle plate. The driving chamber is formed in the top of the monitoring equipment body, the working chamber is formed in the bottom of the driving chamber, the signal transmission device is arranged on the inner wall of the working chamber, and the laser scanner is arranged at the bottom of the monitoring equipment body. The situation that winged insects and particulate matter collide with the laser scanner under the relative acting force is avoided, meanwhile, dust on the surface of the laser scanner can be cleaned, the precision of the laser scanner is improved, the influence of collision on the laser scanner can be reduced, the laser scanner is protected, the working stability of the equipment is improved, and the service life of the equipment is also prolonged.

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. Trains run on fully enclosed lines. The lines located in the central urban area are basically set up in underground tunnels. 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 tunnel al...
