Description

Technical Field

[0001] The utility model relates to the technical field of mining cameras, in particular to a dust-proof structure for a mining camera lens. Background Art

[0002] Mine cameras are video surveillance equipment used for image capture and transmission at important locations underground in coal mines. They are suitable for coal mines containing explosive mixed gases such as methane and hydrogen and with explosion hazards. They can achieve real-time monitoring and transmit the production site conditions underground to the monitoring center in real time, so that managers can understand the production status in a timely manner and discover and deal with safety hazards. In addition, when a safety accident occurs, mine cameras can record the scene of the accident and provide strong evidence for accident investigation.

[0003] Mining cameras are generally composed of an explosion-proof shell and a movement, and the movement is fixed in the explosion-proof shell. The movement consists of some modules such as a power board, an optical terminal, a camera, and an infrared fill light. In order to adapt to the harsh environment of coal mines, mining cameras usually use industrial-grade materials, such as international 304 stainless steel, to meet the safety production needs of coal mines. Since the air in the mine contains a lot of dust, it is easy to block the camera lens. Some mining cameras will set a dust scraping strip in front of the camera lens to scrape off the dust. Keeping the lens clean makes the video clearer.

[0004] However, since the air in the mine contains too much dust, the scraper strip will be attached with more dust after being used for a long time. The longer the use time, the worse the cleaning effect, and the scraper strip needs to be cleaned frequently. In view of this, the present application proposes a dust-proof structure for mining camera lenses. Utility Model Content

[0008] Furthermore, four air outlets are provided on one side of the dust cover, and the four air flow pipes all pass through the air outlets and extend to the interior of the dust cover.
