A push-pull fire door

Abstract

The invention provides a push-pull fire door, which includes a fire door panel, a telescopic rod, a door handle, a pressure sensor, a smoke control switch, an LED guide device, a battery, an electromagnet, a current controller, a pulley, and a guide rail. The characteristic of horizontal opening is that it will not open or close at will due to the pressure change caused by the high-speed operation of the vehicle. At the same time, in order to prevent the push-pull fire door from opening horizontally at will, a telescopic rod and an electromagnet are installed, relying on the inner spring of the telescopic rod. Due to the elasticity and the attraction of the electromagnets in the fire door panels on the left and right sides, the push-pull fire door is tightly closed. In the event of a fire, it can guide people to evacuate to the communication channel. At the same time, it can assist people in opening the fire door. After the people pass through the fire door Automatically close the fire door to evacuate people and prevent the spread of fire and smoke.

Description

technical field [0001] The invention relates to a push-pull fire door, in particular to a fire door applied to a tunnel communication passage. Background technique [0002] In tunnel engineering, the communication channel is a safe evacuation channel. The two ends of the communication channel are respectively connected to the traffic tunnel. The traffic tunnel at the other end of the passage, so the communication passage is often set in long tunnels, super long tunnels and super long tunnels to ensure that people can evacuate in time and safely when emergencies occur, and the main disaster that threatens people's safety is the tunnel fire. One, when a fire breaks out in a tunnel, the communication channel not only ensures the safe evacuation of personnel, but also becomes a channel for the spread of smoke and fire. Fire doors must be installed in the tunnel, because the high-speed operation of the vehicles in the tunnel causes drastic pressure changes in the tunnel. If ordi...

[0002] In tunnel engineering, the communication channel is a safe evacuation channel. The two ends of the communication channel are respectively connected to the traffic tunnel. The traffic tunnel at the other end of the passage, so the communication passage is often set in long tunnels, super long tunnels and super long tunnels to ensure that people can evacuate in time and safely when emergencies occur, and the main disaster that threatens people's safety is the tunnel fire. One, when a fire breaks out in a tunnel, the communication channel not only ensures the safe evacuation of personnel, but also becomes a channel for the spread of smoke and fire. Fire doors must be installed in the tunnel, because the high-speed operation of the vehicles in the tunnel causes drastic pressure changes in the tunnel. If ordinary fire doors are used, the drastic pressure changes will easily cause frequent longitudinal opening of the fire doors, which will seriously affect driving safety and shorten fire protection. service life of the door
