Laser distance measuring sensor with dustproof mechanism for coal bunker

Abstract

The invention discloses a laser distance measuring sensor with a dustproof mechanism for a coal bunker. The sensor comprises a box body and an isolation body arranged in the box body, the isolation body divides the box body into an airflow channel and an inner cavity, the inner cavity is internally provided with a distance measuring machine, a power supply and a controller, the box body is provided with a display, the upper part of the airflow channel is provided with an air filter, an induced draft fan corresponding to the air filter is arranged in the airflow channel, an opening communicated with the airflow channel is formed in the lower portion of the isolation body, explosion-proof glass is arranged in the opening, a dust exhaust device corresponding to the explosion-proof glass is arranged on the lower portion of the box body, and the dust exhaust device comprises a dust exhaust window. A dustproof cover plate capable of being opened and closed is arranged on the dust exhaust window, the using is safer, the situation of pulverized coal explosion can be prevented, the dustproof cover plate capable of being opened and closed is arranged, when the sensor is not used, the dustproof cover plate can be closed in time, and interference of coal ash when the sensor is not used can be avoided.

Description

technical field [0001] The invention relates to the field of ranging sensors, in particular to a laser ranging sensor for a coal bunker with a dust-proof mechanism. Background technique [0002] With the rapid development of science and technology in modern society, the accuracy and time-varying requirements of coal level detection in coal bunkers are higher, so it is gradually necessary to introduce better and more convenient measures in large quantities for further improvement and improvement , especially in view of the relatively weak development of our country, it is even more necessary to find reliable and feasible measures to gradually improve in order to achieve better results. [0003] Nowadays, laser ranging sensors are usually used to detect coal levels. However, due to the harsh environment of coal bunkers, the existing laser sensors are usually more complicated in equipment, and the detection accuracy is greatly affected by changes in the refractive index of the ...

Problems solved by technology

[0003] Nowadays, laser ranging sensors are usually used to detect coal levels. However, due to the harsh environment of coal bunkers, the existing laser sensors are usually more complicated in equipment, and the detection accuracy is greatly affected by changes in the refractive index of the air. The distance measuring head of the laser head is easily damaged by coal. Covered with ash, the anti-interference ability is poor, and it is prone to explosion after entering a large amount of coal ash dust
