Drainage system applied to electric cable well

Abstract

The invention discloses a drainage system applied to an electric cable well. The bottom surface of the electric cable well is lower than the ground, a plane in which an electric cable in the electric cable well is positioned is higher than the bottom surface, the drainage system comprises a submerged pump arranged in the electric cable well and used for discharging ponding water in the electric cable well, and a driving part for driving the submerged pump to work by monitoring the water level of the ponding water, the submerged pump is provided with a water inlet pipe axially adhered to the bottom surface and a drain pipe used for leading the ponding water out of the electric cable well, and the water level of the ponding water is lower than the plane in which the cable well is positioned. The drainage system provided by the invention adopts the driving part to monitor the water level of the ponding water so as to drive the submerged pump to drain away water, unmanned and automatic water drainage is achieved, manual duty water drainage is not required, and a floating ball structure has a simple structure, and is low in cost and strong in applicability.

Description

technical field [0001] The invention relates to a drainage system, in particular to a drainage system applied to a cable well. Background technique [0002] Cables are often laid in low-lying areas, and the cable position is below the ground. When external rainfall occurs, water seepage often occurs, causing the water level to be higher than the cable laying position. When the water level is higher than the cable, the cable will be immersed in water, which will reduce the insulation performance of the cable sheath, affect the work of the electrical circuit, and cause the equipment and facilities of the steel structure to rust and corrode, and even lead to circuit paralysis and endanger personal safety . In the prior art, the cable wells are generally laid in the dark, and the cable trenches are located below the ground, so natural drainage cannot be realized, and artificial drainage is used, which requires a large amount of labor and a high cost. SUMMARY OF THE INVENTION ...

AI Technical Summary

Problems solved by technology

When the water level is higher than the cable, the cable will be submerged in water, which will reduce the insulation performance of the cable sheath, affect the work of the electrical circuit, and cause corrosion and corrosion of the equipment and facilities of the steel structure. In severe cases, it will even lead to paralysis of the circuit and endanger personal safety.

In the prior art, the cable wells are generally laid in the dark, and the cable trench is located below the ground, so natural drainage cannot be realized. However, artificial drainage requires a large amount of labor and high costs.
