Description

Coal-coiling instrument with automatic dustproof outer cover and lens cleaning function Technical Field The invention relates to the technical field of coal-coiling instruments, in particular to a coal-coiling instrument with an automatic dustproof outer cover and a lens cleaning function and a remote control system thereof, which are used for improving the working stability and maintenance efficiency of the coal-coiling instrument in a dust environment. Background Currently, for coal storage, a coal-coiling instrument based on image processing is mostly adopted, and a large number of coal-coiling instruments are arranged on a working surface. In practical application, larger dust is generated in the coal storing and taking process of the working face, and meanwhile, the working face also contains larger water vapor concentration, so that the glass mirror surface at the front end of the camera lens arranged on the working face can be adhered to water vapor and dust in the air to pollute the mirror surface, the collected image of the camera is blurred, the quality of the collected image data is affected, no better removing method exists at present, the shooting effect of a camera is seriously affected, as shown in fig. 1, the installation position of the camera is limited on the working face, most of the camera is installed at the high position of a coal storage bin and needs to be lifted, and the part of the camera needs to be prone to be cleaned on the working face of a thin coal layer, so that the camera lens is inconvenient to clean, unsafe, not only is the cleaning workload increased, but also the mirror surface of the camera cannot be cleaned in real time, the timeliness and reliability of collected image data analysis are greatly reduced, the remote function of a monitoring center cannot be implemented, and the unmanned technology of the working face is greatly restricted.
