Mining intrinsically safe pan-tilt camera

Abstract

The invention discloses a mining intrinsically safe pan-tilt camera, which comprises a main machine body, a pan-tilt mechanism and a windscreen wiper mechanism; the windscreen wiper mechanism comprises a mounting seat, a brush arm and a rubber doctor blade, the mounting seat is arranged on the outer edge of the lower side of the mainboard shell, the brush arm is hinged to the mounting seat, the rubber doctor blade is arranged on the brush arm, and the outer side of the rubber doctor blade is in an arc shape matched with the side wall of the lens spherical shell; and an elastic component is arranged between the brush arm and the mounting seat, so that the rubber doctor blade is tightly pressed and attached to the side wall of the lens spherical shell, and when the holder mechanism rotates, the rubber doctor blade can scrape coal ash on the surface of the lens. The pan-tilt camera has the advantages that the pan-tilt lens part can be kept clean through the windscreen wiper mechanism, the pan-tilt mechanism and the mainboard shell are designed in a double-bearing mode, the spherical sealing cover in the pan-tilt mechanism is exquisite in structural design, the connection and transmission effects are achieved, meanwhile, the good sealing performance is achieved, and disassembly and maintenance are easy.

Description

technical field [0001] The invention relates to the field of monitoring camera equipment, in particular to a mining intrinsically safe pan-tilt camera. Background technique [0002] At present, the mode of setting monitoring camera equipment is usually adopted to realize real-time monitoring under the mine, but there are many deficiencies in the existing mine camera monitoring equipment. First of all, it is impossible to effectively overcome the problem of coal dust covering the lens. Due to the harsh environment in coal mines, large coal dust, and insufficient light, the lens is easily covered by coal dust accumulation when the camera is used in the working surface, reducing the image quality or even completely losing it. The monitoring screen, so it needs to be cleaned in time, and the camera is often installed at a high place, which is difficult to clean. The convenient cleaning method is to manually flush it with water, but it is very easy to damage the equipment, and th...

Problems solved by technology

First of all, it is impossible to effectively overcome the problem of coal dust covering the lens. Due to the harsh environment in coal mines, large coal dust, and insufficient light, the lens is easily covered by coal dust accumulation when the camera is used in the working surface, reducing the image quality or even completely losing it. The monitoring screen, so it needs to be cleaned in time, and the camera is often installed at a high place, which is difficult to clean. The convenient cleaning method is to manually flush it with water, but it is very easy to damage the equipment, and the workers are not motivated to clean the camera equipment in time; In some existing cameras with self-cleaning function, a brush is installed next to the pan / tilt. When the pan / tilt rotates, the brush scrapes off the soot on the lens. The degree of cooperation between the brush and the lens is poor, and the cleaning effect is not ideal.

Secondly, the pan / tilt structure of the existing camera has insufficient airtightness, it is difficult to disassemble and maintain, and it is difficult to replace some parts if there is a failure. Generally, it can only be replaced as a whole, which is expensive
