A mining intrinsic safety type optical fiber camera

Abstract

The invention discloses a mining intrinsic safety type optical fiber camera. The intrinsic safety type camera comprises an intrinsic safety type camera body, an Illuminating lamp and a mounting bracket;the illuminating lamp comprises a lamp holder, a Shell and a supporting frame, wherein a battery box is arranged on the shell; The bottom of the supporting frame is fixedly connected with a fixing plate. a groove II is formed in the intrinsic safety type camera body; a slot is formed in one end of the groove II; a Pressing plate is hinged to the other end of the groove II, a spring is mounted atthe bottom of one end of the pressing plate; The installation support comprises a stand column, a base and a connecting rod connected between the stand column and the base, one end of the connectingrod is movably connected with the stand column through a universal joint, the other end of the connecting rod is fixedly connected with an inserting block; a long groove and a tensioning screw which correspond to the inserting block are installed on the base, and through holes are formed in the four corners of the base. Compared with the prior art, the mining intrinsic safety type optical fiber camera has the advantages that adjustment, replacement, maintenance and disassembly are convenient, meanwhile, the illumination function is achieved, the workload is greatly reduced, and adaptability ishigh.

Description

Technical field [0001] The invention relates to the technical field of mining camera, in particular to an intrinsically safe optical fiber camera for mining. Background technique [0002] The mine intrinsically safe fiber optic camera is used in the environment containing explosive gas underground in coal mines. It is used for on-site photography and can be connected to the network to complete the image data transmission. Due to the harsh underground environment of the coal mine, the camera is prone to failure, while the current traditional mine Intrinsically safe cameras are generally composed of a front cover, a barrel, a rear cover and a mounting bracket. The camera body is fixed on the surrounding wall through an integral mounting bracket. Therefore, it is troublesome to disassemble during adjustment, replacement and maintenance, which will increase Workload. In addition, there will be occasional power outages in the mine. The brightness in the mine is dark and it is easy to ...

[0002] Intrinsically safe optical fiber camera for mining is used in the environment containing explosive gas underground in coal mines. Intrinsically safe cameras are generally composed of a front cover, a barrel, a rear cover and a mounting bracket. The camera body is fixed on the surrounding wall through the integrally formed mounting bracket. Therefore, it is troublesome to disassemble during adjustment, replacement and maintenance, and it will increase In addition, there will be occasional power outages in the mine, and the brightness in the mine is dark, which is easy to cause personal injury. However, most of the existing intrinsically safe optical fiber cameras only have the functions of video recording and alarm, but do not have special circumstances. The ability to provide lighting needs to be improved
