Description

Technical Field

[0001] The utility model belongs to the technical field of fire detection devices, in particular to a fire detection device for electrical equipment. Background Art

[0002] Fire detectors are devices used in fire alarm systems to detect fires on site. Fire detectors are the "sensory organs" of the system, and their function is to monitor whether there is a fire in the environment. Once there is a fire, the characteristic physical quantities of the fire, such as temperature, smoke, gas, and radiation intensity, are converted into electrical signals, and the fire alarm controller is immediately activated to send an alarm signal.

[0003] The publication number "CN217957502U" and the name "A protective device for fire detectors of electrical equipment" discloses a fire detection device, which mainly increases the support effect between the working outer box and the working inner box through the first support plate, thereby increasing the protective force and improving the protective effect. However, the structure of the device is fixed and cannot fix detectors of different specifications. At the same time, the support plate is large in size and easily blocks the transmission of smoke and temperature, affecting the normal operation of the detector. Utility Model Content
