Description

Technical Field

[0001] The utility model relates to the technical field of safety equipment, in particular to a construction site fire alarm device. Background Art

[0002] There are many flammable items such as wood and many tools needed for construction stored on construction sites. When the tools are working, the high temperature and sparks generated may ignite the wood and other flammable items, causing a fire, so a fire alarm device is needed.

[0003] China's utility model patent publication number CN212750041U discloses a construction site fire prevention device, which senses the ambient temperature through a hot-melt adhesive strip. If the temperature exceeds the melting point of the adhesive strip, the adhesive strip melts, causing the position of the connecting column to change. The change in the position of the connecting column will cause the air inlet to open, thereby allowing external air and smoke to enter. If the smoke concentration reaches the fire index, an alarm will be sounded through an external device connected to the sensor. If only temperature and smoke are used for identification, when there is a large amount of smoke or very high temperature in strong winds or cold weather, serious damage to the site is often caused; China's utility model patent publication number CN219263667U discloses a forest fire alarm device, which uses a camera image to identify the fire starting point for the principle of fire identification. Single identification is prone to misidentification, and in view of the construction site environment, the camera is prone to dust or dirt. As the equipment is installed for a longer time, the fire source identification becomes slower and less sensitive, posing a great safety hazard. Utility Model Content
