Description

Technical Field

[0001] The utility model belongs to the field of underground mine cameras, in particular to a self-cleaning structure for an explosion-proof camera window. Background Art

[0002] In order to remove dust from the camera in the prior art, the first method is to set up a wiper-like device, which uses a motor to drive a swing arm in a fan-shaped motion to clean the glass. The swing arm is equipped with a wiper rubber and a water spraying device, which sprays water while the wiper moves. The second method is to stick a waterproof film on the glass and set up a water spraying device to wash away dust, coal slag and other foreign matter with the water flow. The third method is to manually confirm the degree of contamination of the glass and wipe the glass manually to ensure the cleanliness of the glass. When the camera is used in the mine, it is affected by the dust in the mine, and its window is more easily contaminated by dust and dirt, resulting in unclear camera observation. It is not convenient to clean it manually when used in the mine. In addition, due to the complex gas in the mine, electrical components cannot be exposed to the outside to avoid safety hazards in the mine. It is difficult to use a motor to achieve the above-mentioned first wiper-like cleaning method. Summary of the Invention
