Fireproof door system special for cable tunnel

Abstract

The invention relates to a fireproof door system special for a cable tunnel. The fireproof door system comprises a plurality of fireproof walls which are mounted in the tunnel at intervals; fireproofdoors are mounted on the fireproof walls through hinges; driving blocks driven by a motor are slidably mounted on the fireproof walls and connected with the bottoms of the fireproof doors through multi-connecting-rod mechanisms; fire behavior detecting devices are mounted on the fireproof walls, and the signal output end of each fire behavior detecting device is electrically connected with a control circuit; the control circuit is connected with a motor controller which is electrically connected with the control end of the motor; and all the control circuits are in communication connection with a remote-end control room in a wired or wireless mode. The fireproof door system has the advantages and effects that the structure is stable and reliable, control is convenient, and ventilation andfire prevention can both be achieved.

Description

technical field [0001] The invention relates to the field of safety protection of cable tunnels, in particular to a special fire door system for cable tunnels. Background technique [0002] With the sharp increase in power demand, the number of cable tunnels has gradually increased, but the potential safety hazards have also increased. In order to ensure the normal operation of the cable tunnel and to protect the safety of the cable property, a fire door must be installed at intervals inside the tunnel. [0003] Common fire doors include normally open fire doors and normally closed fire doors. For normally open fire doors, if a fire breaks out in the tunnel, it will be difficult for the staff to arrive in time and close the fire door, and the flame will pass through the fire door and enter the other section of the cable tunnel, which will expand the loss of the accident. The role of fire prevention. For normally closed fire doors, it will cause poor ventilation in the tun...

AI Technical Summary

Problems solved by technology

For normally open fire doors, if a fire breaks out in the tunnel, it will be difficult for the staff to arrive in time and close the fire door, and the flame will pass through the fire door and enter the other section of the cable tunnel, which will expand the loss of the accident. The role of fire prevention

For normally closed fire doors, it will cause poor ventilation in the tunnel, increase the ambient temperature, and more prone to cable fire accidents
