[0002] The drilling video recording device is a device used to observe the internal conditions of the borehole. It is widely used in geological surveys, engineering inspections and other fields. It can visually observe and analyze the borehole wall structure, such as stratum lithology, rock structure, faults, cracks, interlayers, karst, and concrete pouring quality. It can also observe the exploration of groundwater activities, water well maintenance, pipe piles and pipelines, etc.

[0003] Chinese patent CN220705692U proposes a video recording device for drilling the entire borehole wall. The device includes a video recording probe and a display. The video recording probe and the display are electrically connected via a signal line. The signal line is reeled and conveyed by an external conveyor. The device also includes a casing sleeved over the outer side of the signal line. The casing is provided with a support assembly for supporting and conveying the signal line within the borehole, and an anti-sway protection assembly for preventing sway during conveyance. The support assembly includes a U-shaped frame arranged in an annular array around the casing. Each U-shaped frame is mounted with a support roller. The casing is provided with an adjustment assembly for adjusting the position of the U-shaped frame. The adjustment assembly includes a threaded tube fixed to the outer side of the casing. A threaded rod is threadedly engaged with the threaded tube. One end of the threaded rod is fixed to the U-shaped frame. The anti-sway protection assembly includes multiple mounting slots that are interconnected and evenly distributed around the casing. The anti-sway protection assembly, the support assembly, and the speed reduction assembly cooperate to support and slow down the signal line during conveyance.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent supports and slows down the signal line during the transportation process through the mutual cooperation of the anti-sway protection component, the support component and the speed reduction component. Since the apertures of the various drill holes are different, during continuous operation, the support rollers need to be adjusted multiple times so that the casing can be supported in the hole, which is more cumbersome and cannot continuously clean the camera protective cover.

[0006] Therefore, those skilled in the art provide a drilling video recording device suitable for holes of different sizes to solve the above problems. Utility Model Content
