Dustproof mining camera

Abstract

The invention discloses a dustproof mining camera. The dustproof mining camera comprises an inner layer sleeve arranged outside a camera body in a sleeved mode, an outer layer sleeve is arranged outside the inner layer sleeve in a sleeved mode, and a gas cavity is formed between the inner layer sleeve and the outer layer sleeve. A front end cover covers the front end of the gas cavity, and a rear end cover covers the tail end of the gas cavity. A gas outlet hole is formed in the front end cover, and a gas inlet hole is formed in the wall of the outer layer sleeve. According to the dustproof mining camera, gas for cleaning enters a cavity defined by the inner layer sleeve, the outer layer sleeve, the front end cover and the rear end cover in an enclosing mode through the gas inlet hole and is blown out through the gas outlet hole, the blown out gas flow generates a gas field in front of a lens to form a dust separation area, thus, dust in the environment can be prevented from falling onto the lens, the lens is kept clean, and it can be guaranteed that pictures can be shot normally and clearly by the camera.

Description

technical field [0001] The invention relates to a camera, in particular to a mine dustproof camera. Background technique [0002] With the application and popularization of roadway intelligent technology, the technology of installing cameras in mines and underground working equipment and other mining machinery to carry out remote visual monitoring of roadway operations has also developed rapidly. Due to the dust in the working environment of mining machinery, the camera lens used for monitoring is easily polluted by dust, which will affect the monitoring image effect. [0003] In order to solve the above-mentioned problem that the camera lens is polluted, the following two methods are mainly used in the prior art: one is to install a nozzle in front of the lens, and to clean the lens by automatically spraying water regularly by the system to keep the lens clean, but this method Additional cleaning water is required, and watermarks are likely to remain on the lens, and the c...

Due to the dust in the working environment of mining machinery, the camera lens used for monitoring is easily polluted by dust, which will affect the monitoring image effect

[0003] In order to solve the above-mentioned problem that the camera lens is polluted, the following two methods are mainly used in the prior art: one is to install a nozzle in front of the lens, and to clean the lens by automatically spraying water regularly by the system to keep the lens clean, but this method Additional cleaning water is required, and watermarks are likely to remain on the lens, and the cleaning effect is not good; in order to solve the problem of washing the lens with water, another method is to set a ring-shaped dustproof cover on the camera, and a ring-shaped dust-proof cover is set on it. The air hole and the air outlet hole, the air enters the annular dust cover from the air inlet hole and is ejected from the air outlet hole. The ejected airflow prevents the dust from approaching the camera lens, forming a dust-proof area in front of the lens, which keeps the lens clean However, the connection between the annular dustproof cover and the camera in this kind of gas dustproof device is unstable and reliable, and it is prone to fall off and damage, resulting in dustproof failure
