Pipe gallery flame retardant device and method

Abstract

The invention provides a pipe gallery flame retardant device. The pipe gallery flame retardant device comprises a smoke sensing device, a pipe gallery air outlet, an exhaust pipe, an exhaust device and a control unit, wherein the smoke sensing device is arranged in a pipe gallery and used for detecting smoke generated in the pipe gallery and sending a flame retardant signal to a control unit whendetecting the existence of smoke; the pipe gallery air outlet communicates with the outside through a gate; the exhaust pipe is arranged on the top of the pipe gallery; the exhaust device is connectedwith the exhaust pipe; and after receiving the flame retardant signal, the control unit controls the gate to be closed to isolate the pipe gallery air outlet from the outside, the exhaust device is started to run and quickly exhaust air in the pipe gallery, and therefore, the fire extinguishing purpose is achieved. When a line in the pipe gallery self-ignites, generated smoke triggers the smoke sensing device, portions communicating with the outside like the pipe gallery air outlet in a fire prevention subarea are blocked after the sensing device sends the signal to the control unit, then theexhaust device is started to quickly exhaust air in the pipe gallery so that the inside of the pipe gallery is lack of oxygen, and then the purpose of fire extinguishing is achieved.

Description

technical field [0001] The invention relates to the field of flame-retardant pipe gallery, in particular to a pipe gallery flame-retardant device and a flame-retardant method. Background technique [0002] With the acceleration of urban construction, the comprehensive pipe gallery continues to develop. It effectively solves the bad phenomena such as road zippers, but the comprehensive pipe gallery itself also has some risks, such as the flame retardancy of the pipe gallery itself. If there are high-voltage lines in the pipe gallery When waiting for the line, when the line spontaneously ignites, it will seriously threaten the use of the utility tunnel itself and the safety of surrounding facilities and personnel. Since traditional methods such as water cannot be used to extinguish fires, a flame-retardant scheme for utility tunnels urgently needs to be proposed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fl...
