Background

Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into miners and opencast mines. When the coal layer is far away from the ground surface, a tunnel is usually dug to the underground to mine the coal, which is a mineworker coal mine. When the coal seam is very close to the earth surface, the coal is generally excavated by directly stripping the earth surface, which is an open pit coal mine. Most coal mines in China belong to underground coal mines. Coal mines encompass a large area above ground and below ground as well as associated facilities. Coal mines are reasonable spaces excavated by humans when excavating geological formations rich in coal and generally include roadways, wells, and mining surfaces, among others. In the acquisition in colliery, need monitor the inside construction, avoid the emergence of potential safety hazard, and current usually directly install the camera and monitor at the mine top, because the environment in the mine is relatively poor, has a large amount of coal ashes, and current camera lacks the protection, leads to coal ash can enter into the inside damage that causes the camera of camera, and the lens department that the coal ash can be attached to the camera simultaneously influences the monitoring effect, in view of this, we provide a colliery roof monitoring device.

Detailed Description

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides a colliery roof monitoring device, includes roof 1, and guard box 2 is installed to 1 bottom surface of roof, and guard box 2 bottom surfaces are connected with translucent cover 3, and camera 4 is installed to 2 lower extreme inner walls of guard box, and the lateral wall communicates respectively about 2 upper ends of guard box has outlet duct 5 and filter tube 6, and motor 7 is installed to 6 left end inner walls of filter tube, and 6 left end downside inner walls of filter tube run through is connected with pivot 8.

Specifically, the collecting pipe 601 is connected to the bottom of the right end of the filter pipe 6 through threads, an inclined ring groove 602 is formed in the inner wall of the right end of the filter pipe 6, an inclined filter plate 603 is in sliding fit in the inclined ring groove 602, the left wall of the inclined filter plate 603 is connected with a plurality of springs 604 in an annular structure, the left end of each spring 604 is connected and fixed with the inner wall of the left side of the inclined ring groove 602, and the inclined filter plate 603 can be reset through the springs 604.
