Problems solved by technology

In such a fully enclosed environment, the heat generated by the cable is not easy to dissipate in time, causing the temperature in the pipe channel to gradually increase, resulting in a gradual decrease in the current carrying capacity of the cable, and ultimately directly affecting the quality and safety of power supply.

Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0016] exist Figure 1~3 Among them, two or more row pipe groups extend into the working well 4 through the well wall from two or more directions, and the above-mentioned row pipe groups communicate with each other through the working well 4; Tube 5 constitutes. A well cover 1 is arranged at the wellhead of the airtight working well 4, and an air inlet pipe 2 and an exhaust pipe 3 communicating with the outside are fixed in the working well 4. In order to improve the efficiency of heat exchange, one end of the intake pipe 2 is erected in the working well 4, and the other end passes through the well wall of the working well 4 to stretch out to the outside; one end of the exhaust pipe 3 is horizontally fixed in the working well 4 and as far as possible Close to the back of the well cover 1, to ensure that the entrance of the exhaust pipe 3 is at the ...

Abstract

The disclosed underground comb channel includes working well, well cover, and comb group. Being composed of multiple underground combs, the comb group is connected to the well. Being connected to outside, a piece of air inlet pipe and a piece of air outlet pipe are fixed in the working well. Features are: simple structure, convenience of construction, and maintenance, no power, no noise, and no pollution, low running cost, well timed adjusting temperature automatically, no need of manual monitoring and managing, and good cooling effect. The invention is widely applicable to build or reconstruct underground comb channel for city distribution network.

Description

Technical field: [0001] The invention relates to an underground pipe-distributing channel, in particular to an underground cable-pipe-distributing channel used in an urban power distribution network. Background technique: [0002] At present, in the reconstruction and construction of the city, it is generally required to use the underground pipe channel to run the cables of the power grid into the ground. The traditional underground pipeline channel is mainly composed of a pipeline group formed by a plurality of pipelines buried below 0.5-0.7 meters underground, a working well connecting each section of the pipeline group, and a manhole cover; in order to waterproof, it is generally required to use Concrete is wrapped around the piping, and a double-layer manhole cover is used, so the entire underground piping channel forms a fully enclosed structure. In such a fully enclosed environment, the heat generated by the cable is not easy to dissipate in time, causing the temperat...
