Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire safety engineering, in particular to a fire smoke and temperature detection device for safety engineering. Background Art
[0002] Fire safety engineering refers to the engineering field that protects the safety of life and property of people in buildings, places or facilities by adopting various scientific fire prevention technologies and equipment, as well as organizational management measures. These projects can include the fire protection design of buildings, automatic fire alarm systems, fire extinguishing systems (such as sprinkler systems, fire extinguishers, etc.), evacuation passage design, smoke and exhaust systems, fire elevators and other aspects of engineering design and construction. The core goal of fire safety engineering is to prevent the occurrence of fires, reduce the losses caused by fires, and ensure that people can be evacuated quickly and orderly when fires occur, and provide necessary convenient conditions for fire fighting. This project needs to comprehensively consider factors such as building structure, materials, equipment and facilities, and personnel behavior to maximize fire safety performance.
[0003] Smoke and heat detection devices are needed in fire safety projects. Although the existing technology has met the needs of users to a certain extent, there are still certain defects in the use process. It is inconvenient to clean the dust attached to the surface of the existing smoke and heat detection devices during use. The accumulation of dust may cause the detection device to have a reduced perception of fire signals, increasing the possibility of false alarms, which will cause unnecessary troubles to managers and firefighters, and may also affect the timely handling of real fire situations. At the same time, dust accumulation on the surface of the detector may cause the detector's sensitivity to decrease, making it unable to detect the smoke or temperature changes released by the fire in a timely and correct manner, delaying the detection time of the fire and affecting the timeliness of emergency response. Long-term dust accumulation will affect the normal operation of the detector and even cause equipment failure, thereby causing the entire fire alarm system to fail, seriously threatening the lives of people in the building. How to clean the dust on the smoke and heat detection devices is a problem that needs to be solved. Utility Model Content
