Abstract

The invention relates to the technical field of fire-fighting equipment, and provides a fire-fighting smoke sensing device which comprises a mounting seat; a sleeve which is arranged on the mounting seat; an alarm main body which is arranged in the sleeve in a sliding manner along the length direction of the sleeve; a sealing mechanism which is arranged at one end of the sleeve and comprises a fixed disc and a plurality of rotating blades, the fixed disc is fixedly arranged on the mounting base, an access hole is formed in the fixed disc and is opposite to a pipe hole of the sleeve, the rotating blades are rotationally arranged on the fixed disc, the rotating blades are arranged in the circumferential direction of the fixed disc, a plurality of rotating blades can close and open the access hole; and a power mechanism which is used for driving the alarm main body and the rotating blade to move. According to the technical scheme, the problem that a smoke alarm in the prior art does not have protection capability and cannot give an alarm continuously when a fire disaster occurs is solved.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a fire-fighting smoke detector. Background technique [0002] Smoke alarms mostly use smoke sensors as the sensing element, and use the smoke emitted by the fire inside the building as the sensing medium to achieve the effect of sounding the alarm. The common smoke alarm has a simple structure and is often installed on the ceiling of the building. Most of the smoke alarms are directly exposed outside. When a fire occurs in the room, the smoke sensor senses the smoke and generates an alarm. However, sometimes when a fire occurs in the room, the high temperature , open flames, etc. will cause damage to the smoke alarm, so that the smoke alarm cannot continue to alarm, so it is necessary to increase the protection ability of the smoke alarm in the event of a fire, so that the smoke alarm can continue to alarm in the event of a fire. Contents of the invention [00...
