Method for laying optical cable inside fire protection vent pipe

Abstract

The invention discloses a method for laying an optical cable inside a fire protection vent pipe. The method comprises the following steps that 1, a lubricant is prepared, the lubricant is injected into the fire protection vent pipe through a hopper, and then the optical cable is laid inside the fire protection vent pipe gradually; 2, while the optical cable is laid, compressed air is blown into the fire protection vent pipe in the optical cable laying direction; 3, after the optical cable is laid, compressed air continues to be blown into the fire protection vent pipe in the optical cable laying direction so as to remove the lubricant inside the fire protection vent pipe. The method has the advantages that the method is simple, convenient and easy to implement, no professional is needed, and laying of the optical cable inside the vent pipe can be completed by one person.

Description

technical field [0001] The invention relates to a method for laying an optical cable in a fire-fighting ventilation pipe. Background technique [0002] With the deepening of the development of the Internet in social life, the requirements for digitalization of fire-fighting vehicles are becoming increasingly strong; therefore, firefighters and command centers need to timely grasp the information of the fire scene and carry out scientific and reasonable fire-fighting work. The use of optical fiber cables can perfectly solve the problem Communication of fire scene information; optical cables for firefighting can be laid in gas pipes dedicated to fire fighting, but the outer sheath of the optical cable and the inner wall of the air pipe are made of polymer materials such as PVC, which causes great friction between the optical cable and the inside of the air pipe, and the optical cable is laid in the air pipe very difficult. Contents of the invention [0003] In order to solv...
