Rapid smoke spectrum detection device

Abstract

The invention belongs to the technical field of smoke detection equipment, and discloses a rapid smoke spectrum detection device, which comprises a detection box, the bottom surface of the detection box is fixedly connected with a connecting block, the bottom surface of the connecting block is fixedly provided with a guide pipe, and the bottom surface of the detection box is fixedly provided with a sensor assembly. The cleaning mechanism is pushed to move through gas, dirt on the inner surface of the guide pipe is scraped away through a scraping ring of the cleaning mechanism, meanwhile, after the cleaning mechanism moves to the limiting position, air is continuously introduced, the air is introduced into a through hole in a mounting base, a sleeve rod in an air spraying mechanism is pushed up, and the dirt on the inner surface of the guide pipe is removed along with upward movement of the sleeve rod and a movable plate. According to the sensor assembly, air enters the air spraying mechanism through the through hole and is sprayed upwards through the air spraying hole of the air spraying mechanism, surface cleaning of the sensor assembly is achieved through the sprayed high-speed air, smoke particles and dust attached to the sensor assembly are effectively cleaned through the wind power effect, and the detection quality of the sensor assembly is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of smoke detection equipment, in particular to a rapid smoke spectrum detection device. Background technique [0002] Fire is a catastrophic burning phenomenon that is out of control in time or space. Among all kinds of disasters, fire is one of the main disasters that most frequently and commonly threatens public safety and social development. Fires are divided into six categories: A, B, C, D, E, and F according to the type and combustion characteristics of combustibles, specifically solid matter fires, liquid or meltable solid matter fires, gas fires, metal fires, and live fires. , Cooking fire in cooking utensils. Different fire causes require different rescue methods. If the wrong rescue method is adopted, it will lead to greater disasters. In order to determine the type of fire in time, a variety of sensors are usually used for smoke detection, and the camera can quickly determine the main combustion ...

Problems solved by technology

[0003] The rapid smoke spectrum detection device in the prior art, in the process of use, in order to enhance the detection efficiency, a guide pipe is usually added to cooperate with the built-in fan to suck air from the environment, so that when a fire occurs and smoke is generated, the smoke flows quickly However, for the detection device actually installed in public places, with the continuous suction for air detection, a large amount of dust adheres to the outer surface of the sensor component of the detection device, which affects the actual and smoke in the air. The contact effect reduces the detection efficiency, and when there is fire smoke, the particles in the dense smoke flow into the guide pipe, and some of them adhere to the sensor assembly, and the actual detection process takes a certain time. When the detection starts, the surface of the sensor assembly adheres A layer of smoky black film affects the quality of continuous detection, cannot quickly complete accurate detection, and the use effect is not good

[0004] In addition, in the rapid smoke spectrum detection device in the prior art, the camera mechanism is installed in the guide tube when it is practical, and the guide tube is made of transparent material, so as to ensure that the camera mechanism installed in the guide tube is protected against the smoke in the guide tube. When testing, there is good lighting, but with continuous suction testing, a large amount of dust in the environment adheres to the inner wall of the transparent guide tube, which gradually reduces the transparency of the guide tube, reduces the brightness in the guide tube, and makes the interior The quality of the image information collected by the camera mechanism decreases, thereby reducing the smoke detection effect and the judgment efficiency of the fire type, and the use effect is not good
