Cable trench with automatic fire extinguishing function for communication base station

Abstract

The invention belongs to the field of communication facilities, and particularly relates to a cable trench with an automatic fire extinguishing function for a communication base station. The cable trench comprises a trench body, a cable rack and a cover plate, wherein a cavity is formed in the trench body; a sliding plate is connected into the cavity in a sealing and sliding manner; the sliding plate is fixedly connected with the bottom surface of the cavity through a memory spring; a closed space formed by the upper surface of the sliding plate and the inner side wall of the cavity is filledwith a fire extinguishing agent; a threaded pipe is fixedly arranged in the sliding plate in a penetrating mode; a fire extinguishing pipe is in threaded connection with the interior of the threaded pipe; a pressure valve is installed in the fire extinguishing pipe; the lower end of the fire extinguishing pipe penetrates through the bottom face of the cavity and extends into the trench body; the fire extinguishing pipe is rotationally connected with the cover plate; and a plurality of spraying pipes are fixedly communicated with the side wall of the fire extinguishing pipe. The cable trench can automatically spray a fire extinguishing agent for rapid and effective fire extinguishing when a fire occurs, the fire extinguishing agent is uniformly sprayed in a large range, fire spreading can be effectively prevented, the fire extinguishing effect is good, and the safety is high.

Description

technical field [0001] The invention belongs to the field of communication facilities, in particular to a cable trench for a communication base station with an automatic fire extinguishing function. Background technique [0002] Cable trench is an underground pipeline for laying and replacing electric power or telecommunication cable facilities. It is also an enclosure structure for cable facilities. There are rectangular, circular, arched and other pipeline structures. Cable trench layout in communication base stations and power plants The type is related to the field equipment and terrain conditions. [0003] Fires often occur in cable trenches due to problems such as high temperature or short circuit of the cable, and it is difficult for the staff to detect the fire in time, which is likely to cause greater damage and loss, and the safety risk is greater. Existing cable trenches are usually painted with fire-resistant paint However, these fire prevention measures have li...

Problems solved by technology

[0003] Fires often occur in cable trenches due to problems such as high temperature or short circuit of the cable, and it is difficult for the staff to detect the fire in time, which is likely to cause greater damage and loss, and the safety risk is greater. Existing cable trenches are usually painted with fire-resistant paint However, these fire prevention measures have limited fire prevention effects and can only alleviate the fire and delay the spread of the fire. They cannot effectively and quickly extinguish the fire, and there are potential safety hazards.
