Automatic fire extinguishing system and method for cable tunnel

Abstract

The invention provides an automatic fire extinguishing system and method for a cable tunnel. The system comprises an inspection robot, a positioning robot and a guide rail fixed to the top in the tunnel; the inspection robot and the positioning robot are connected with the guide rail, and the positioning robot is arranged in a groove of the inspection robot and can move along the guide rail under the driving of the inspection robot; and the positioning robot can independently enter or exit from the internal space of the inspection robot along the guide rail and is used for controlling a built-in fire extinguishing mechanism to extinguish a fire at a preset position away from the fire source. Through the arrangement of the inspection robot and the positioning robot, both fire-fighting medium butt joint and fire extinguishment are achieved; and through the cooperation of a first locking mechanism and a second locking mechanism, rapid battery taking and placing are achieved, and the cable tunnel fire extinguishment inspection efficiency is improved.

Description

technical field [0001] The present disclosure relates to the technical field of cable tunnel fire protection, in particular to an automatic fire extinguishing system and method for cable tunnels. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] A cable tunnel is a corridor or tunnel structure used to accommodate a large number of cables laid on cable supports. In addition to allowing the tunnel to better protect the cables, the cable tunnel can also make it easy for people to inspect and repair the cables. Due to the long-term operation of the cable, the cable in the cable tunnel is prone to fire due to the damage of the cable insulation layer. Once the cable catches fire, it will seriously affect the normal operation of the power line. [0004] The inventor found that if fire probes or sprinklers are arranged in the cable tunnel, the c...

AI Technical Summary

Problems solved by technology

Due to the long-term operation of the cable, the cable in the cable tunnel is prone to fire due to the damage of the cable insulation layer. Once the cable catches fire, it will seriously affect the normal operation of the power line.

[0004] The inventor found that if fire probes or sprinklers are arranged in the cable tunnel, the cost is high and maintenance is inconvenient; most of the existing inspection robots for cable tunnels adopt an integrated design, and the built-in fire extinguisher is used to extinguish the fire. The fire extinguishing effect is small and the fire extinguishing effect is poor; most of the existing cable tunnel robots adopt the configuration of one robot, which cannot realize the balance between fire extinguishing and fire fighting medium docking; most of the existing cable tunnel robots are powered by batteries, and the patrol inspection of cable tunnels The route is long, the battery cannot be charged in time, and the inspection efficiency is low
