Description

Technical Field

[0001] The utility model belongs to the technical field of mining equipment, and in particular relates to a flameproof and intrinsically safe camera for mining. Background Art

[0002] Mine cameras are used in safety monitoring systems in underground production environments of coal mines, and play a very important role in production safety activities. Through real-time monitoring of the working conditions, operating status, and abnormal conditions of electromechanical equipment by cameras, the construction behavior of workers can be standardized, and the safety hazards existing at the construction site can be discovered and resolved in a timely manner. It can also help relevant regulatory authorities to conduct real-time detection of the production work of coal mining enterprises to avoid illegal operations by production enterprises. At present, when the location of the mine camera is dusty, after a period of use, the camera end cover and the lighting end cover will be attached with a lot of dust, blocking the camera and affecting the lighting brightness.
