Embodiment Construction
[0018] Such as figure 2 As shown, the device for automatically cleaning the flame detector of the present invention is used to clean the flame detector. The flame detector 1 includes: an infrared filter 11; a sampling, amplification, and frequency selection circuit 12; a central processing control unit 13; and Alarm output, communication unit 14. The device 2 of the automatic cleaning flame detector of the present invention comprises: a stepping motor 21, a belt drive 22, and a cleaning brush 23 installed on the infrared filter 11, and the stepping motor 21 drives the cleaning brush through the belt drive 22 23 moves back and forth, and then the infrared filter 11 is cleaned.
[0019] Further, the stepping motor 21 is driven to rotate by the central processing control unit 13 through the built-in stepping motor driving module, and the cleaning brush 23 is driven to move by the belt and the pulley of the belt transmission device 22 . The central processing control unit 13 ha...

The invention discloses a device for automatically cleaning flame detectors, which comprises a stepping motor, a belt driving device and a cleaning brush installed on an infrared filter, wherein the stepping motor drives the cleaning brush to move back and forth through the belt driving device so as to clean the infrared filter. The invention also discloses a method based on the device for automatically cleaning flame detectors, which comprises the following steps: timing by a central processing and control unit after a flame detector is powered; starting the stepping motor to rotate after reaching the preset time; and further driving the cleaning brush to move back and forth by the belt driving device to clean the infrared filter. The invention avoids the work of manually timed cleaning,is much favorable to the warning accuracy of the flame detector, automatically cleans the surface of a filter at certain times and enhances the warning accuracy of the flame detector by a software algorithm changed by the central processing and control unit.
Description
technical field [0001] The invention relates to a cleaning device for a flame detector, in particular to a device for automatically cleaning a flame detector. The invention also relates to a method for automatically cleaning a flame detector. Background technique [0002] With the rapid development of my country's economic construction, the number of large space buildings and underground buildings is increasing, such as large public entertainment places, large warehouses, large bazaars, hangars, garages, oil depots, waiting halls and waiting halls, underground tunnels , subway station road, underground large parking lot and underground commercial street, etc. Because the interior of this type of building is often elevated and spanned, the smoke diffusion at the initial stage of the fire is greatly affected by the air-conditioning and ventilation systems installed inside the building. The fire spreads rapidly, the smoke generated is highly toxic, and it is difficult to evacu...
