A real-time dust removal and cooling device and method for a camera lens in a high dust environment

Abstract

The invention discloses a real-time dust removal and cooling device and method for a camera lens in a high-dust environment, which belongs to the technical field of dust removal equipment and is set on the camera lens, including an air inlet joint, an air guide wall, an inner air outlet part and an outer air outlet part. The air wall is set on the camera lens. The bottom of the air guide wall is provided with an air inlet joint for connecting to a clean low-temperature compressed air source. The top of the air guide wall is provided with an inner air outlet and an outer air outlet. The guide part of the inner air outlet hole is ejected from the top lens of the camera lens through the compressed air of the air guide wall. Air is ejected from the front of the camera lens. The technical solution provided by the invention can clean the dust on the lens of the camera in real time in the working environment of a large amount of dust during the mining process of the coal mine, and at the same time play the role of cooling the lens to improve the quality of the camera.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a real-time dust removal and cooling device and method for a camera lens in a high dust environment. Background technique [0002] During the coal mining process, a large amount of dust will be generated. Due to the narrow and humid roadway space, the underground mining environment is extremely harsh. With the advancement of intelligent mining in coal mines, a large number of visible light and infrared cameras will be installed in the roadway, especially near the mining face. In the above-mentioned high-dust and humid environment, a large amount of dust or mud will adhere to the camera lens, which will blur the camera lens, resulting in inaccurate or even impossible data collection. At present, the camera lens is usually manually cleaned periodically. This method is not only easy to damage the lens, time-consuming and laborious, but also cannot be cleaned in real ...

AI Technical Summary

Problems solved by technology

Therefore, there will be a white edge around the image collected by the infrared camera, which is caused by the high temperature around the lens of the infrared camera.

The appearance of white edges will have a strong interference effect on the images collected by the infrared camera, reducing the quality of camera collection

At the same time, because the coal mine excavation process is a high gas and dusty environment, some conventional cooling methods cannot be applied
