Description

Technical Field

[0001] The utility model relates to the technical field of flame detection, in particular to a flame detector probe structure. Background Art

[0002] Flame detectors are devices used to detect and monitor flames and are widely used in various industrial and commercial locations to ensure safety and prevent fires. Flame detectors determine the presence of flames by detecting the characteristics of flames, such as spectrum, flicker frequency, and infrared / ultraviolet radiation; flame detectors are an important part of fire prevention and safety management. By detecting flames in a timely manner and activating the alarm system, the hazards of fire to people and property can be greatly reduced.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figures 1 to 3The utility model provides a technical solution: a flame detector probe structure, including a probe body 1, a detection end 101 fixed to one end of the probe body 1, a guide ring 4 is fixedly sleeved on the surface of the probe body 1, a circle of guide grooves 401 are arranged on the surface of the guide ring 4, a rotatable ring 2 is movably sleeved in the guide groove 401, a support plate 9 is fixedly connected to the surface of the ring 2, an air pump 7 is fixedly installed on the support plate 9, a nozzle 8 is fixedly connected to the gas delivery end of the air pump 7, and the outlet of the nozzle 8 is arranged toward the detection end 101.

[0023] Start the air pump 7, and the high-pressure gas generated is sprayed toward the surface of the detection end 101 through the nozzle 8, blowing off the dust on the surface of the detection end 101, thereby cleaning the detection end 101; at this time, since the ring 2 can rotate and make a circular motion, the nozzle 8 makes a circular motion synchronously, which can fully clean the detection end 101, thereby ensuring that the detection end 101 can accurately identify and detect the flame, thereby improving the detection accuracy of the probe body 1.

[0024] In order to drive the ring 2 to rotate, a motor 5 is fixedly installed on the circumferential side wall of the probe body 1, and a gear 6 is fixedly connected to the output end of the motor 5. A plurality of transmission teeth 3 equidistantly distributed around the circumference are fixedly connected to the circumferential side wall of the ring 2, and the transmission teeth 3 are meshed with the gear 6.

[0025] The tooth top circle diameter of the gear 6 is smaller than the distance between the tooth top of the transmission tooth 3 and the center of the ring 2, thus achieving the purpose of speed reduction, allowing the ring 2 to rotate slowly and steadily, and finally allowing the nozzle 8 to clean the detection end 101 steadily and fully.

[0026] The motor 5 is started to drive the gear 6 to rotate. The gear 6 is meshed with the transmission tooth 3 to drive the ring 2 to rotate. The ring 2 drives the support plate 9, the air pump 7 and the nozzle 8 to make a circular motion.

[0027] There is a clearance fit between the circular ring 2 and the guide ring 4 to reduce the friction resistance between them, so that it is convenient for the circular ring 2 to rotate on the surface of the guide ring 4.
