This flexible adjustment capability improves monitoring efficiency and reduces monitoring blind spots.

[0031] Working principle: When using the monitoring and alarm device for the safety of sand and gravel mines, the monitoring and alarm device fixing plate 14 is fixedly installed as needed, and it is determined whether to be installed on the top surface or the wall according to actual conditions, and the fixing plate 14 is firmly installed in the selected position through the fixing block 18 using the fastening bolts 19. After real-time monitoring, the third motor 15 can be started, and the third motor 15 drives the second threaded rod 16 to rotate, and the second threaded rod 16 drives the connecting block 1 to move, and at the same time, the connecting block 1 is limited by the slide groove 17, so that the connecting block 1 moves horizontally on the fixing plate 14, thereby adjusting the monitoring and alarm device to a suitable position. In cases of insufficient light, dynamic scenes, occlusion, etc., when the pitch angle of the infrared monitoring camera 24 needs to be adjusted, the first motor 4 is started to drive the first threaded rod 5 to rotate, and the threaded block 6 on the first threaded rod 5 moves up and down accordingly, and the third connecting rod 8 is driven up and down by the connecting strip 7, thereby changing the angle between the third connecting rod 8 and the vertical line, realizing the infrared monitoring camera 2 4 can also be used to adjust the pitch angle of the camera 24, and the second motor 11 can also be started. The second motor 11 drives the driven worm gear 13 to rotate through the active worm gear 12, and the driven worm gear 13 drives the rotating rod 9 to rotate. The infrared monitoring camera 24 rotates together with the rotating rod 9, thereby realizing the horizontal angle adjustment of the infrared monitoring camera 24. When the position and angle of the monitoring alarm device are adjusted, the infrared monitoring camera 24 starts to work. The infrared transmitting module 21 built into the infrared monitoring camera 24 continuously emits infrared rays. These infrared rays will be reflected when encountering objects, and the reflected infrared rays are received by the infrared receiving module 22. When a person or object enters the sensing range of the infrared ray, the reflection of the infrared ray will change, and this change will be detected by the infrared receiving module 22, thereby triggering the alarm module 23 to sound an alarm. After receiving the abnormal signal from the infrared receiving module 22, the alarm module 23 will immediately trigger an alarm, which may be a sound alarm or a flashing light alarm. Be careful not to block the infrared alarm component 20 during installation.
