Description

Technical Field

[0001] The utility model relates to the technical field of coal mine equipment, in particular to a lens cleaning device and a drilling peep instrument. Background Art

[0002] During coal mine exploration, workers install a lens at one end of the probe rod and push the lens into the borehole through the probe rod to peer into the borehole. As the lens is pushed into the borehole, the surface of the lens is easily contaminated and blurred by the soil and water in the borehole, affecting the clarity of the lens imaging and making it impossible to accurately peer into the borehole. In addition, as the lens is pulled out to peer, it may still be blurred by the rock debris or running water remaining around the hole wall, affecting the peering effect. Furthermore, if the peering depth is large, a large amount of rock ash is likely to remain in the hole, and the rock ash floating in the hole will also reduce the clarity of the peering and affect the peering effect.

The liquid spraying structure 20 sprays liquid to the surface of the lens 60 to clean the surface of the lens 60, so that the image captured by the lens 60 is clearer. With this solution, the problem of the surface of the lens 60 being contaminated by dirt and water is solved.
