Description

TECHNICAL FIELD

[0001] The utility model belongs to coal mine safety monitoring technical field, concretely relates to a coal mine safety monitoring device. BACKGROUND

[0002] In the coal mine transportation process, the transportation belt in the coal mine is used for transporting coal to the designated place, in order to monitor the deviation of the belt and the damage of the belt surface in real time during use, it is usually necessary to set a monitoring device in the mine, such as a high-definition camera, which monitors the deviation of the belt and the damage of the belt surface through intelligent analysis technology to ensure the safe and stable conveying of the belt to the coal.

[0003] In the monitoring device, a high-definition camera is currently mainly used for real-time monitoring, in order to protect the camera, a protective device is often arranged outside the camera, such as the dustproof coal mine safety monitoring device disclosed in the utility model with the authorized announcement number CN215819015U, which realizes the protection of the camera by setting a dustproof box, a box door, a transparent window and a sealing strip attached to the front end of the dustproof box, thereby blocking the dust from adhering to the camera, thereby ensuring the service life of the camera; However, the above-mentioned device can monitor the safety of the transportation belt in the mine, however, due to the humid environment in the mine and the sealing strip being arranged outside the dustproof box, the moisture in the air is in constant contact with the sealing strip, which can accelerate the aging of the sealing strip, thereby affecting the dustproof effect of the monitoring device; At the same time, due to the large amount of dust in the mine, the outer surface of the transparent window is easy to accumulate dust when used for a long time, which affects the camera's view and leads to poor use effect of the whole monitoring device.

[0004] Based on this, the utility model provides a coal mine safety monitoring device to solve the problems existing in the prior art. UTILITY MODEL CONTENTS
