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

Embodiment 1
[0061] Embodiment 1 of the present disclosure provides an automatic fire extinguishing system for a cable tunnel, which includes:
[0062] guide rail, which is fixed on top of the cable tunnel;
[0063] An inspection robot is arranged to move along the guide rail, and a first driving mechanism is arranged on the inspection robot, and the inspection robot walks along the guide rail under the action of the first driving mechanism;
[0064] The battery is arranged in the battery slot on the inspection robot, and the inspection robot is provided with a first locking mechanism for locking the battery;
[0065] A charging unit, which is arranged on the side wall of the cable tunnel, is used to charge the battery;
[0066] A positioning robot, which is arranged on the inner side of the inspection robot, is provided with a second driving mechanism on the mobile robot, and the positioning robot moves along the guide rail under the action of the second driving mechanism, and is provide...
Embodiment 2
[0093] Embodiment 2 of the present disclosure provides an automatic fire extinguishing method for a cable tunnel, including the following steps:
[0094] Step 1: Monitor the fire in the cable tunnel through the inspection robot installed in the cable tunnel;
[0095] Step 2: When a fire is found, the inspection robot quickly moves to the fire source and moves to the nearest docking pipe;
[0096] Step 3: The fire extinguishing mechanism is connected with the docking pipe to realize the connection between the fire extinguishing pipeline and the fire extinguishing mechanism;
[0097] Step 4: The positioning robot moves out of the inspection robot until it moves to the place closest to the fire source;
[0098] Step 5: Extinguish the fire source through the fire extinguishing mechanism.

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...
