Problems solved by technology

[0003] The dust sensor in the prior art does not have the function of dust prevention, and the wire interface is easy to enter the dust during use, resulting in the accumulation of dust on the guide interface, which is prone to rust and poor contact; the dust photosensor in the prior art is in use. Dust that enters the sensor can easily enter the position of the photosensitive element and adhere to the photosensitive element, reducing the sensitivity of the photosensitive element. Therefore, an optical principle dust sensor with the function of preventing dust from entering is needed to solve the above problems

Abstract

The invention provides an optical-principle based dust sensor with a dust prevention function. The optical-principle based dust sensor comprises an upper shell, a lower shell, a guide line connector,a connector protection component and an internal dust prevention component. The upper shell is mounted at the upper end of the lower shell. The guide line connector is formed in the right end face ofthe upper shell. The connector protection component is provided with a guide line connector position, and is mounted on the right end face of the upper shell. The internal dust prevention component isassembled in the lower shell. The connector protection component comprises a fixing frame, a sleeve, a micro heat-radiating fan, a mounting groove, a connection rod, a push rod, an annular sliding groove and an arc-shaped plate. The internal dust prevention component comprises an air flow channel, a limiting platform, a carrying platform, a positioning rod, a spring piece, a moving rod, a movinggroove, a roller and a cleaning block. Compared with the prior art, the optical-principle based dust sensor has the advantages that dust prevention and heat radiation of the guide line connector are realized, internal dust prevention of the sensor is also realized, and dust is prevented from adhering to photosensitive elements to reduce sensitivity.

Description

technical field [0001] The invention is an optical principle dust sensor with the function of preventing dust from entering, and belongs to the technical field of dust detection. Background technique [0002] The dust concentration sensor is mainly used for continuous monitoring of the total dust concentration in dusty workplaces such as mines and cement plants. It is a high-tech sensor developed by using the principle of laser scattering to meet the needs of existing coal mine monitoring underground dust concentration. , On-site, continuous and uninterrupted monitoring to display the dust concentration in the well, and at the same time output the switching signal of the dust suppression device for water spraying and spraying, to achieve the best effect of dust measurement and dust reduction. [0003] The dust sensor in the prior art does not have the function of dust prevention, and the wire interface is easy to enter the dust during use, resulting in the accumulation of du...
