A miniature automatic fire door for a cable tunnel

Abstract

The invention discloses a miniature automatic fire door for a cable tunnel. A door frame is arranged on the outside of the fire door body, grooves are arranged on both sides of the top middle of the door frame, the inside of the groove is filled with fire extinguishing agent, and a glass cover is installed on the outside of the groove , the upper and lower ends of both sides of the door frame are equipped with fixing plates, the two sides of the inside of the door frame are provided with a storage chamber, the top of the storage chamber is provided with a chute, the inside of the storage chamber is installed with a door leaf, and the lower left corner of the inside of the door frame is installed with an R280 motor. One end of the R280 motor is fixedly connected with a rotating shaft, and one end of the rotating shaft is installed with a driving gear. Connection, simple operation, convenient installation and disassembly, when the glass cover is damaged after a fire, it can also be replaced, simple and practical, and reduces the later maintenance cost of the fire door body.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a miniature automatic fire door of a cable tunnel. Background technique [0002] Cable tunnel refers to a corridor or tunnel structure used to accommodate a large number of cables laid on cable supports. For the convenience of construction, maintenance and inspection, there are generally pedestrian maintenance roads in the tunnel, and a fire door is set tens of meters apart. In the event of a fire, it is used to prevent the penetration and spread of flames and reduce property losses. The space of the cable tunnel is narrow and long, usually about 1.8 m high and 1.5 m wide. In some places where cables are less replaced, the width and height are less than 1 m In these places, due to the small space, human inspection is very dangerous and inconvenient, so robots will be used instead of manual inspections. Most of the existing fire doors for robots are simple and have single funct...

[0002] Cable tunnel refers to a corridor or tunnel-like structure used to accommodate a large number of cables laid on cable supports. For the convenience of construction, maintenance and inspection, there are generally pedestrian maintenance roads in the tunnel, and a fire door is set tens of meters apart. In the event of a fire, it is used to prevent the penetration and spread of flames and reduce property losses. The space of the cable tunnel is narrow and long, usually about 1.8 m high and 1.5 m wide. In some places where the cable replacement is less, the width and height are less than 1 m In these places, due to the small space, human inspection is very dangerous and inconvenient, so robots will be used instead of manual inspections. Most of the existing fire doors for robots are simple and have single functions. It has the effect of further extinguishing the fire, and the practicability is poor. In addition, most fire doors are only equipped with a single sensor, which is prone to misjudgment when alarming, which leads to unnecessary losses and increases the cost of fire extinguishing.
