Problems solved by technology

Underground cables are often buried underground. After entering the modern society, due to the shortage of urban land, high traffic pressure, and city appearance construction, large cities generally use underground cables for power transmission. Underground cables are easily damaged or corroded due to their underground environment. Most underground cables are installed in pipes, which are used to isolate the external environment, so as to achieve the purpose of protecting the cables. However, multiple cables are placed in one pipe, which is not convenient for cable maintenance, and the heat generated by the cables during use is not enough. It is easy to dissipate and affect the service life of the cable

Abstract

The invention belongs to the technical field of cables, and particularly relates to an underground cable protection device. The device comprises a bottom plate, supporting plates are arranged on the two sides of the bottom plate, a plurality of triangular supporting frames are arranged at the top ends of the supporting plates, upper-layer supporting rods and lower-layer supporting rods are arranged in the middles of the supporting plates in the height direction, a U-shaped pipe is arranged at the top end of the bottom plate and is provided with a plurality of air outlets, and the air inlet endof the U-shaped pipe is connected with a cooling device and a dosing device. The cable protection device is simple in structure, the multiple cables are arranged in the protection device in sequence,maintenance is facilitated when the cables break down, the temperature and humidity in the protection device can be adjusted, deinsectization rodenticide can be sprayed into the protection device atregular time, the cables are prevented from being bitten by insects and mice, and when the water level in the protection device reaches a certain height, the alarm gives out alarm sound, and the cables are prevented from being wetted by water; and when no pressure exists between fixing buckles and the cables, the alarm gives out alarm sound to prevent the cables from being stolen.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to an underground cable protection device. Background technique [0002] A cable is a wire made of one or more mutually insulated conductors surrounded by an insulation and a protective layer, and is used to transfer power or information from one place to another. Underground cables are often buried underground. After entering the modern society, due to the shortage of urban land, high traffic pressure, and city appearance construction, large cities generally use underground cables for power transmission. Underground cables are easily damaged or corroded due to their underground environment. Most underground cables are installed in pipes, which are used to isolate the external environment, so as to achieve the purpose of protecting the cables. However, multiple cables are placed in one pipe, which is not convenient for cable maintenance, and the heat generated by the cables during us...
