A safety monitoring equipment for coal mine

Abstract

The invention relates to safety monitoring equipment for coal mines, comprising an intrinsically safe monitoring camera and an outer casing of a device. The intrinsically safe monitoring camera can be lifted and lowered in the outer casing of the device, and a lifting support is arranged below the intrinsically safe monitoring camera. The upper part of the lifting support plate is provided with a monitoring and adjustment device; the inner bottom of the device shell is provided with a lifting cylinder, the piston rod end of the lifting cylinder is connected to the center of the bottom of the lifting support plate, and the left and right sides of the lifting cylinder are respectively provided with follow-up baffle devices The upper end of the follow-up baffle device is provided with an overturned protective baffle, and the top of the outer casing of the device is provided with a lifting and exiting inlet, and the protective baffle can switch the lifting and lowering inlet and outlet with the expansion and contraction of the lifting cylinder. The present application overcomes the problems of the prior art, the camera device is flexibly adjusted and controlled from multiple angles, has hidden protection, and provides high-strength protection when it is not working.

Description

technical field [0001] The present application relates to monitoring for coal mines, and in particular, to a safety monitoring device for coal mines. Background technique [0002] With the improvement of the degree of mechanization of coal mines, the production capacity and production efficiency of mines have generally increased, and the coal output has increased year by year, but at the same time, the safety situation of coal mines is not optimistic. In recent years, gas explosions, coal and gas outbursts and other disasters have seriously threatened the safety of coal mines and the lives of millions of coal miners. [0003] The coal mine monitoring device can obtain monitoring images of the coal mine site for the back-end staff to view. Due to the limited monitoring range, it is necessary to set up multiple and evenly distributed in the coal mine roadway, so that the entire coal mine can be observed for safety monitoring. [0004] The existing patent publication number is...

Problems solved by technology

However, for this device, when gravel debris hits and falls on the protective shell, it will also cause shock damage to the monitoring device, and the flexibility of the monitoring equipment is not enough to provide a sufficient monitoring range, so it is urgently needed make improvements
