[0045] Working principle: First, before the peep lens enters the mine, it is connected to the safety rope through the winding ring 11 and the connecting rod 10 to prevent the peep lens from accidentally falling off or falling rapidly. The searchlight 12 fixed on the top of the main body 1 is turned on to provide lighting for underground work and ensure that the peep lens can clearly capture the situation inside the coal mine.

[0046] Start the camera 18. At this time, the pin 13 at the bottom of the main body 1 is connected to the cable 14. The cable 14 provides power to the camera 18 and transmits the captured data back to the host or controller. There is a driving source inside the main body 1. The driving source provides power to control the rotation of the rotating shaft 15, thereby driving the protective shell 16 to rotate. When the protective shell 16 rotates as a whole, it will drive the rotating shaft 17 and the camera 18 to rotate around the rotating shaft 15. Since a power source is provided between the protective shell 16 and the rotating shaft 17, the rotating shaft 17 can be driven to rotate, thereby driving the camera 18 to rotate, thereby realizing multi-angle shooting of the inner wall of the mine by the camera 18.

[0047] When the peep lens falls, there will be attachments on the surface of the camera 18. The power slider 29 in the slide rail 30 is driven by the power provided by the protective shell 16 to slide (the power slider 29 is an existing technology and will not be described in detail here), thereby driving the brush 27 connected to the connecting rod 28 to slide, removing the debris attached to the surface of the camera 18 to ensure that the lens remains clear. When the camera 18 needs to be cleaned, the water tank 19 on the inner wall of the main body 1 transports water to the water pipe 2 22 through the water pump 21, and the camera 18 will rotate to the appropriate position, so that the straight pipe 25 and the water pipe 2 22 are magnetically connected through the magnetic interface 1 23 and the magnetic interface 2 24 (and the long hose will be wrapped around the outside of the protective shell 16 when the protective shell 16 rotates, affecting the rotation of the camera 18 and the shooting of the camera 18), allowing water to be transported from the water pipe 22 to the straight pipe 25, and finally sprayed through multiple spray heads 26.

[0048] Finally, when the falling speed of the peep lens suddenly increases, the motor 2 drives the telescopic rod 3 to realize telescopic movement, and the hook claw 4 extends under the drive of the telescopic rod 3 and contacts the mine wall, thereby increasing friction, slowing down the falling speed of the peep lens, and preventing it from being subjected to severe impact. The fixed block 5 is connected to the outside of the main body 1 by bolts 6 for easy replacement. At the same time, the elastic rod 7 and spring 8 on the fixed block 5 play a buffering role. When the peep lens is still falling and the falling speed is slowed down, or when the peep lens is about to be placed at the bottom of the mine and the falling speed is slowed down, the collision head 9 will first contact the ground, and the elastic rod 7 and spring 8 absorb part of the impact force to prevent the camera 18 from being damaged.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
