Fire extinguishing equipment with alarm for electric power tunnel

Abstract

The invention relates to fire extinguishing equipment with an alarm for an electric power tunnel. The fire extinguishing equipment comprises a plurality of fireproof devices arranged in the electric power tunnel, and each fireproof device comprises a roller shutter type fireproof door and an access controller for controlling the opening and closing of the roller shutter type fireproof door; the roller shutter type fireproof doors divide the electric power tunnel into a plurality of fire-fighting sections, and each fire-fighting section is internally provided with an electric power tunnel sensor network unit, and an audible and visual alarm, a spraying fire extinguishing device, a plurality of smoke detectors and a plurality of cable temperature sensors which are connected with the electricpower tunnel sensor network unit; and each access controller is connected with each electric power tunnel sensor network unit in adjacent fire-fighting sections, the fire extinguishing device comprises a water source and a plurality of spray heads communicating with the water source, and a control valve for controlling a main branch pipeline to be opened or closed is arranged on the main branch pipeline. According to the fire extinguishing equipment with the alarm for the electric power tunnel, and on-line monitoring and instant fire extinguishing of fire in the electric power tunnel can be realized.

Description

technical field [0001] The invention relates to the field of electric tunnel construction, in particular to an alarm-equipped fire-fighting equipment for electric tunnels. Background technique [0002] A power tunnel is a corridor or tunnel structure used to accommodate a large number of cables laid on cable supports. In addition to allowing the tunnel to better protect the cables, the cable tunnel can also make it easy for people to inspect and repair the cables. Due to the flammability of cables, there are many potential fire sources in power tunnels, which makes the fire prevention and fire prevention problems of power tunnels more prominent. Once a fire occurs in power tunnels, it will spread rapidly and cause damage to electrical equipment, threatening personal lives. Safety, leading to power outages, and even more serious consequences, it is very difficult to repair. Therefore, it is necessary to pay more attention to the fire prevention of power tunnels, raise fire ...
