Cable trench cable fire alarm and automatic fire extinguishing device

Abstract

The invention relates to the technical field of cable fire-fighting equipment, and discloses a cable trench cable fire alarm and automatic fire extinguishing device. The device comprises a cable trench, wherein the cable trench is arranged on the ground in a front and back manner. According to the cable trench cable fire alarm and automatic fire extinguishing device, fire extinguishment is automatically started in time when a fire occurs in the cable trench, cable is prevented from being damaged, the range of power failure caused by accidents is narrowed down, and serious consequences such asoverride trip are prevented; a buzzer is arranged, a probe signal receiving device senses signals sent by a smoke sensing and temperature measuring probe and then is electrically connected with the buzzer, an alarm can be given out in time when a power cable is on fire, maintenance personnel can be informed in time to carry out maintenance on the cable, heavy economic losses are avoided, and furthermore, normal electricity utilization of common users and enterprises is indirectly guaranteed; and a sliding rail, a first gear and a threaded rod are arranged, so that a fire extinguishing box canreach any place in the cable trench, and fire extinguishment with dry powder can be conducted on any place in time.

Description

technical field [0001] The invention relates to the technical field of cable fire-fighting equipment, in particular to a cable trench cable fire alarm and automatic fire extinguishing device. Background technique [0002] With the continuous and rapid growth of my country's economy, the demand for domestic electricity and business electricity is increasing. As one of the main ways to transmit electric energy, the reliability of power cables is of great significance. At present, under the influence of various factors such as cable design, production, installation and maintenance, and operating environment, power outage accidents caused by cable damage are in a state of high incidence, which is one of the important hidden dangers for the safe operation of the power grid. [0003] The monitoring of the cables in the cable trench during operation is through the daily inspection of the on-duty staff. The method is single and cannot be directly observed.

AI Technical Summary

Problems solved by technology

At present, under the influence of various factors such as cable design, production, installation and maintenance, and operating environment, power outages caused by cable damage are in a high-incidence state, which is one of the important hidden dangers for the safe operation of the power grid.

[0003] The monitoring of the cables in the cable trench during operation is through the daily inspection of the on-duty staff. The method is single and cannot be directly observed. It is difficult to find out the hidden dangers of fire or unsafety during the operation of the cables in time.

A fire in a cable trench is highly concealed, has a wide range of influence, and takes a long time to repair and recover. Once it occurs, it may cause serious consequences

In addition to causing cable damage, cable fires may also cause serious consequences such as equipment tripping, supply load reduction, and even injury to firefighters.

Not only will it bring serious losses to the economy, but it will also disrupt the normal life and production order of residents and enterprises.
