Coal mine closed roadway unsealing dangerous gas source monitoring device based on automatic mining

Abstract

The invention discloses a coal mine closed roadway unsealing dangerous gas source monitoring device based on automatic mining, and relates to the technical field of coal mine internal gas intelligent monitoring equipment.The coal mine closed roadway unsealing dangerous gas source monitoring device comprises a base and a bearing plate, the bearing plate is located above the base, and a sliding groove plate is welded to the top of the base; a hinge rod is slidably connected to the inner wall of the sliding groove plate, the top of the hinge rod is slidably connected with the left side of the base, and the bearing plate is movably connected with the base through the hinge rod. The electric hydraulic rod is arranged between the base and the bearing plate for combination, the height of the camera recorder can be adjusted according to the underground condition, rotation between the first rotating rod and the second rotating rod is matched, the underground condition can be conveniently recorded in all directions, and the gas detection device, the alarm lamp and the buzzer are arranged in a combined mode, so that the detection efficiency is improved. When the underground gas concentration is detected to reach a certain value, the alarm lamp can be used for reminding.

Description

technical field [0001] The invention relates to a monitoring device, and relates to the technical field of gas intelligent monitoring in an unmanned mining department in a coal mine, in particular to a monitoring device for a dangerous gas source based on unsealing of a closed roadway in an automatic mining coal mine. Background technique [0002] At present, my country's coal mines have shifted from shallow mining to deep mining. The roadway layout system of deep mines is more complicated, and closed roadways are set up according to the purpose. In order to continue mine production, it is necessary to unseal the previously constructed closed roadways. The environment is extremely complex, and the light is insufficient, the distribution and content of hazardous gases are not clear, and it is very easy to be dangerous when affected by mining. [0003] There are following problems at prior art: [0004] 1. In the prior art, for unmanned coal mines, robots are mostly used for d...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a monitoring device for dangerous gas sources based on the unsealing of closed tunnels in automatic mining coal mines. One of the purposes is to improve the effect of prompts and solve the problem of poor sound prompts; the other purpose It is to solve the problem of installing the gas detection device on the car body or the wall of the coal mine, so as to achieve the effect of easy installation of the gas detection device. Another purpose is to have the gas detection device installed on the car body, which is convenient for gas The detection device is moved and detected, which is beneficial to detect the gas concentration in other areas inside the mine, and solves the problem of low applicability of the gas detection device
