Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a digital safety monitoring device for coal mines. Background Art

[0002] Before mining, coal mines need to use monitoring devices to detect the conditions inside the coal mines, thereby improving the safety of mining. Traditional coal mine safety monitoring devices generally use handheld gas content monitors to detect the gas content in the coal mines. When using traditional coal mine safety monitoring devices, workers are required to enter the coal mines with handheld monitoring, which will still have a certain impact on the safety of the workers. At the same time, some locations with relatively narrow terrain are not conducive to workers entering and exploring the conditions in narrow locations, which can easily leave safety hazards.

[0003] In response to the above problems, the existing patent publication number CN220626305U, entitled A Coal Mine Safety Monitoring Device, proposes a technical solution. By setting up an auxiliary mechanism, when it is necessary to monitor the coal mine, the automatic mobile frame can be started by remote control, and the camera and other devices can be driven into the coal mine by the automatic mobile frame. Then, the camera and detection unit are remotely turned on, and the conditions in the mine are monitored through the camera and detection unit. The monitoring data is remotely fed back through the transmission unit, so that when the monitoring device monitors the coal mine, there is no need for workers to enter handheld, and it can automatically enter for monitoring, thereby improving the safety of the monitoring process.

[0004] However, when the coal mine safety monitoring device disclosed in the appealed patent is used, if it encounters relatively uneven road conditions, the coal mine safety monitoring device is prone to tipping over, thereby affecting the monitoring progress. Therefore, it is necessary to propose a coal mine digital safety monitoring device to solve the above problem. Utility Model Content
