Embodiment Construction

[0041] Such as Figure 1 to Figure 15 As shown, the inspection system of the present invention mainly includes a guide rail 2, an inspection box 3, a drive unit, a battery 4, a first locking mechanism, a second locking mechanism, a loading and unloading unit, and a monitoring unit. A detailed description.

[0042] Such as figure 1 As shown, the cable 11 is usually arranged in the middle and lower part of the cable tunnel 1, and the cable is relatively fixed to the side wall of the cable tunnel. A guide rail 2 is fixed on the top of the cable tunnel, and the guide rail is laid along the direction of the cable tunnel. A track groove 21 is arranged at the bottom of the guide rail, and a rack 22 is fixed at the bottom of the guide rail between the two track grooves.

[0043] There is an inspection box 3 under the guide rail, such as figure 2 As shown, the inspection box is a square structure, and four wheel frames 31 are fixed on the top of the inspection box. It is arranged...

Abstract

The invention provides a cable tunnel fire prevention and early warning inspection system and inspection method. The system includes a guide rail fixed on the top of the cable tunnel, an inspection box slidably arranged along the guide rail, and the top of the inspection box is used to drive the inspection box along the guide rail. Mobile drive unit, removable battery, first locking mechanism in the inspection box to lock the fixed battery and inspection box, loading and unloading unit on the side wall of the cable tunnel, second locking mechanism on top of the battery, inspection The monitoring unit at the bottom of the box. During the inspection, the inspection box moves at a constant speed along the guide rail, and the monitoring unit at the bottom of the inspection box works to monitor the fire situation. The battery in the inspection box is detected in real time and moved to the nearest charging unit for charging. The invention can be used to realize the real-time monitoring of the cable tunnel, and discover the fire situation in the cable tunnel in time.

Description

technical field [0001] The invention relates to the technical field of cable tunnel fire monitoring, in particular to a cable tunnel fire prevention early warning inspection system and inspection method. Background technique [0002] 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. [0003] Therefore, it is necessary to monitor the cable tunnel in real time, so as to discover the fire in the cable tunnel in time. Contents of the invention [0004] The object of the present invention is to provide a cable tunnel fire prevention...
