Example Embodiment

[0033] Example 1

[0034] like Figure 1-5 As shown, the present embodiment provides a cable trench and a cable trench drainage system, including a cable trench body 1, a drainage channel 6 and a water collecting well 3. The cable trench body 1 includes a cable trench 11, several cable supports 5 and a cable trench Cover plate 2, the cable bracket 5 is arranged on the side wall of the cable trench 11, the cable trench cover plate 2 is arranged on the upper part of the cable trench 11, and the drainage channel 6 includes a water inlet section 12 and an elbow section. 14 and the water outlet section 15, one end of the water inlet section 12 is communicated with the bottom of the cable trench 11, the other end of the water inlet section 12 is communicated with one end of the elbow section 14, and the other end of the elbow section 14 is communicated with the One end of the water outlet section 15 is connected, the other end of the water outlet section 15 is communicated with the...

Example Embodiment

[0041] Embodiment 2

[0042] This embodiment is an improvement made on the basis of Embodiment 1. In Embodiment 1, after the accumulated water is discharged into the water collecting well 3, it mainly enters the soil through recharge, generally without human intervention, but when it is in the rainy season or relatively low-lying When the water level in the collecting well 3 is too high, there is a certain degree of safety hazard. A cover plate 4 is set at the wellhead of the collecting well 3 to prevent accidental falling. In addition, a drain pipe 17 and a pumping pump 18 are set at the wellhead of the collecting well 3. The accumulated water in the water collection well 3 is pumped and drained to avoid excessive accumulation of water. If necessary, a water level gauge can be added for observation.

Abstract

The invention provides a cable trench and a cable trench drainage system, and belongs to the technical field of electric power facilities. The cable trench comprises a cable trench body, a drainage channel and a water collecting well, the cable trench body comprises a cable trench, a plurality of cable supports and a cable trench cover plate, the cable supports are arranged on the side wall of the cable trench, the cable trench cover plate is arranged on the upper portion of the cable trench, the drainage channel comprises a water inlet section, a bent pipe section and a water outlet section, one end of the water inlet section is communicated with the bottom of the cable trench, the other end of the water inlet section is communicated with one end of the bent pipe section, the other end of the bent pipe section is communicated with one end of the water outlet section, the other end of the water outlet section is communicated with the side wall of the water collecting well, and an anti-backflow device is arranged at the position where the side wall of the water collecting well is communicated with the water outlet section. The cable trench is good in sealing performance, cables are arranged in a layered and branched mode and can be arranged in order to facilitate laying and overhauling, meanwhile, the anti-backflow drainage system is arranged, accumulated water in the cable trench is reduced, and the cables are prevented from being damped and damaged.

Description

technical field [0001] The invention relates to the technical field of electric power facilities, in particular to a cable trench and a cable trench drainage system. Background technique [0002] With the continuous deepening of the transformation and construction of my country's power grid, power cables have been widely used. The use of power cables can not only effectively reduce the workload of operation and maintenance, but also greatly improve the reliability of power supply and ensure the safety of the national grid operation. At present, the cable trench laying scheme is widely used in substations, which has the advantages of simple building structure, few additional supporting facilities such as technical defense, low engineering investment, and high economic efficiency. However, due to the long-term operation of power cables underground, the operating environment has high humidity, the environment in the ditch is relatively airtight, the moisture cannot be discharg...
