An underground safety monitoring device and monitoring method for gobs based on Beidou satellite

Abstract

The invention discloses a goaf safety monitoring device and monitoring method based on the Beidou satellite, comprising an L-shaped plate, a vertical rod fixedly connected to the top of the L-shaped plate, and a control device fixedly installed on the outer side of the vertical rod. Box, the present invention is compact in structure, simple and convenient in operation, and strong in practicability. By setting up a safety monitoring camera that can be adjusted up and down, it is convenient to adjust and maintain it, and at the same time avoids the staff from climbing, which greatly reduces the safety. Hidden dangers, and by setting the snap-in mechanism, the security monitoring camera can be quickly disassembled and replaced, which greatly improves the efficiency of disassembly and replacement, and does not need to be screwed multiple times, thus avoiding the occurrence of slipping wires, which is extremely The service life of the equipment is greatly extended. In addition, by setting the rotation adjustment mechanism and the angle adjustment mechanism, the orientation angle and inclination angle of the security monitoring camera can be quickly adjusted, which is beneficial to practical use.

Description

technical field [0001] The invention belongs to the field of monitoring devices, in particular to an underground safety monitoring device and monitoring method based on Beidou satellite goaf. Background technique [0002] In the current life, China's Beidou satellite navigation system is a global satellite navigation system developed by China, and it is also the third mature satellite navigation system after GPS and GLONASS. It is a supplier recognized by the United Nations Satellite Navigation Committee, and the goaf is a cavity created by artificial excavation or natural geological movement under the surface. The existence of the goaf makes the safety production of the mine face great safety problems. Equipment may fall into the goaf and be injured, and monitoring the downhole in the goaf is a necessary measure to ensure safety. The application of the Beidou satellite to the downhole monitoring device in the goaf is also an existing technical solution. [0003] However, w...

Problems solved by technology

[0003] However, most of the existing goaf safety monitoring devices based on Beidou satellite are directly installed on the wall of the underground cavity when they are in use. There are certain potential safety hazards in adjustment and maintenance. At the same time, when the existing Beidou satellite-based goaf safety monitoring devices are used, most of them are installed and fixed by screws. When it needs to be disassembled and replaced, many more Only by turning the screw once can it be disassembled and replaced, which not only reduces the efficiency of disassembly and replacement, but also easily causes the phenomenon of wire slipping when the screw is turned many times, which greatly reduces the service life of the equipment. At the same time, the existing Beidou-based When the satellite goaf underground safety monitoring device is in use, its orientation angle and inclination angle are mostly fixed and inconvenient, and cannot be adjusted quickly, which is not conducive to actual use
