Description
Technical Field
[0001] The utility model relates to the technical field of fire protection engineering, in particular to a fire protection temperature sensing cable alarm detection tool. Background Art
[0002] In the modern building fire safety system, fire-fighting temperature-sensing cables are used as an important early warning device for fires in various places, such as warehouses, tunnels, cable trenches, etc., to monitor abnormal changes in ambient temperature, issue alarms in time, and prevent fire accidents. Such cables usually have built-in temperature-sensitive components. When the ambient temperature exceeds the preset threshold, the alarm system will be triggered, thereby achieving rapid response and fire control.
[0003] However, in practical applications, regular inspection and maintenance of fire-fighting temperature-sensing cables are key links to ensure their normal function. Traditional detection methods often rely on manual operation, which is not only inefficient, but also more difficult for temperature-sensing cables installed in complex or difficult-to-reach locations, which can easily lead to inaccurate or missed detections, increasing safety hazards. In addition, due to the different cable diameters and the need to simulate the heating state of the cables in a real fire environment to verify their temperature sensing performance, the detection process is complicated and has high technical requirements for operators, which also increases the labor burden of operators. Therefore, we propose a fire-fighting temperature-sensing cable alarm detection tool. Utility Model Content
