[0002] In recent years, my country's photovoltaic power generation industry and wind power generation industry have developed rapidly. As an important part of the power generation system, the substation plays an important role in boosting the generated electric energy and feeding it back to the power grid. In the substation, the cable trench connects various power distribution equipment like "blood vessels", so the importance of the cable trench is self-evident.

[0003] The traditional cable trench waterproofing design method usually designs the side walls of the cable trench to be higher than the ground, and then lays a prefabricated cover on top. However, this design method cannot completely solve the waterproofing problem of the cable trench, and there is still the problem of water accumulation inside the cable trench. At the same time, the cable trench above the ground also poses certain safety hazards to operation and maintenance personnel. Summary of the invention

[0004] The utility model aims to solve the problem of water accumulation in the existing cable trench and provides a cable trench anti-drainage device which can reduce the influence of rainfall on the cable trench.

[0005] The utility model of cable trench drainage device is arranged above the main body of the cable trench in the substation plant area, and is characterized in that the drainage device comprises a waterproof mechanism, a drainage pipe and a water accumulation well, the waterproof mechanism is arranged horizontally, and the interior of the main body of the cable trench is divided into an upper part and a lower part, the upper part is a waterproof trough, and the lower part is a cable trough; the tail end of the waterproof mechanism is connected to the drainage pipe, and the tail end of the drainage pipe is connected to the water accumulation well; wherein:

[0006] The waterproof mechanism includes an outer limiting plate, an inner limiting plate, a connecting piece and a waterproof bottom plate. The waterproof bottom plate is arranged horizontally, two inner limiting plates are arranged vertically on both sides of the waterproof bottom plate, and two outer limiting plates are arranged vertically on the outside of the inner limiting plate. The inner limiting plate is fixedly connected to the outer limiting plate on the same side by a connecting piece.

[0007] The waterproof mechanism is an integrated, convenient, detachable plastic or stainless steel structure. The array of waterproof mechanisms is practical to connect. The length of each group of waterproof mechanisms is 1000 to 2000 mm. The height of the outer limiting plate is not less than 20 cm, and the height of the inner limiting plate is not more than 10 cm. The width of the waterproof bottom plate is the same as the net width of the cable trench body, the width of the connecting piece is the same as the thickness of the cable trench wall, the inner limiting plate is attached to the inner wall of the cable trench, and the outer limiting plate is wrapped around the outer wall of the cable trench.

[0008] A waterproof baffle is also provided at the end of the last group of waterproof mechanisms, and a drainage port is provided on the waterproof baffle. The drainage port is connected to a drainage pipe, and rainwater collected by the waterproof mechanism enters the water well through the drainage pipe.

[0009] The waterproof mechanism has the same slope as the cable trench body, and the slope of the waterproof mechanism is not less than 5‰.

[0010] The cable trench drainage device of the utility model has a simple structure, convenient drainage and easy installation. The seepage water entering the cable trench can be effectively collected in time by arranging a waterproof mechanism, and uniformly discharged into the water collection well, thereby reducing the impact of rainfall on the cable trench. The recovered seepage water can be used for watering the green area of ​​the substation site after simple treatment. BRIEF DESCRIPTION OF THE DRAWINGS
