Problems solved by technology

[0003] Therefore, in order to reduce the harm caused by fire, people will use fire shutters to reduce the speed of slowing down the spread of fire. However, the existing fire shutters are often electrically controlled to be lowered and unfolded. When a fire occurs, the circuit is prone to disconnection. , so that the fire shutter cannot be used normally. Therefore, a fire shutter self-triggering system is proposed

Abstract

The invention discloses a fireproof roller shutter self-triggering system. The fireproof roller shutter self-triggering system comprises a shell and a rotatable winding and unwinding roller arranged in the shell, wherein a fireproof roller shutter body is arranged on the winding and unwinding roller; a balance weight plate is embedded in the end, away from the winding and unwinding roller, of thefireproof roller shutter body; the right end of the winding and unwinding roller extends to the outer portion of the shell; a limiting mechanism for limiting rotation of the winding and unwinding roller is arranged on the outer side of the shell and comprises an inner cavity formed in the side wall of the shell; memory metal is fixedly connected to the inner top of the inner cavity; a rack is arranged at the lower end of the memory metal; the side wall of the rack is in sliding connection to the inner side of the inner cavity; a rotation shaft is rotationally connected to the inner side of theinner cavity; and the outer side of the rotation shaft is sleeved with a magnetic block and a gear. According to the fireproof roller shutter self-triggering system, when a fire disaster happens, a fireproof roller shutter can be automatically unfolded under the action of the balance weight plate and the gravity of the fireproof roller shutter, carbon dioxide in a carbon dioxide storage cavity can be sucked out, and the fireproof effect is achieved.

Description

technical field [0001] The invention relates to the technical field of fire shutters, in particular to a self-triggering system for fire shutters. Background technique [0002] In daily life, fires occur from time to time, and the occurrence of fires often catches people off guard. Fires can cause great harm to people's personal safety and property safety, and can destroy many families. Usually, firefighters are called for rescue by calling the fire alarm, but it will take some time for firefighters to arrive at the scene of the fire, and the fire will not wait for anyone. [0003] Therefore, in order to reduce the harm caused by fire, people will use fire shutters to reduce the speed of slowing down the spread of fire. However, the existing fire shutters are often electrically controlled to be lowered and unfolded. When a fire occurs, the circuit is prone to disconnection. , so that the fire shutter cannot be used normally. Therefore, a fire shutter self-triggering system ...
