A mining intrinsically safe camera

Abstract

The invention discloses an intrinsically safe camera head for mining, which comprises a camera tube. A control box is fixedly installed on the outer surface of the camera tube near the bottom end through a throat hoop, and a front fixing ring is welded on the outer surface of the front end of the camera tube. , and the inner center of the front fixing ring is bonded with a lens near the front end. In the mine intrinsically safe camera described in the present invention, each component inside the camera is installed in the component installation box in advance, and a slide rail is installed between the component installation box and the camera at the same time, so that the component installation box can carry All components installed inside slide out together, which is convenient for maintenance personnel to observe and repair, and reduces the difficulty of device repair. The positive and negative copper sheets are respectively installed inside the circuit board, and the magnet sheet is installed between the copper sheet and the pin. , Connect the pins of the LED lamp to the circuit board through the magnet sheet, which is convenient for manual replacement and repair of the damaged LED lamp, which is simple and convenient.

Description

technical field [0001] The invention relates to the field of cameras, in particular to an intrinsically safe camera for mine use. Background technique [0002] With the application and popularization of roadway intelligent technology, the technology of installing cameras in mines and underground working equipment and other mining machinery for remote visual monitoring of roadway operations has also developed rapidly; [0003] There are certain drawbacks in the existing intrinsically safe camera for mine use, (1), when repairing the internal device of the camera, it is necessary to use tools to remove the shell of the camera, and then repair and repair the various parts inside the device. Inspection, because each component is installed inside the camera, and the internal space of the camera is small, it is inconvenient to observe and repair, and secondly, due to the compact installation of each component and the intricate wiring, it further increases the difficulty of repair;...

[0003] There are certain drawbacks in the existing intrinsically safe camera for mine use, (1), when repairing the internal device of the camera, it is necessary to use tools to remove the shell of the camera, and then repair and repair the various parts inside the device. Inspection, because each component is installed inside the camera, and the internal space of the camera is small, it is inconvenient to observe and repair, and secondly, due to the compact installation of each component and the intricate wiring, it further increases the difficulty of repair; (2), Since the mining camera needs to be used in the mine for a long time, and the light in the mine is insufficient, it is necessary to install lighting equipment to supplement the shooting of the camera, and in order to cooperate with the work of the camera, the lighting equipment needs to be illuminated for a long time to reduce the LED light. Second, the installation of LED lamps in existing lighting equipment is fixed with the circuit board by soldering. When one or more LED lamps are damaged, there are two methods. One is to repair the circuit board. Replacement of the board as a whole, because the other LED lights are not damaged, the overall replacement will cause a certain waste of resources; another method is to remove the damaged LED lights first, and then re-solder the new LED lights, this process is too cumbersome, cutting It is easy to cause damage to the circuit board. Therefore, we propose a mining intrinsically safe camera
