Description

Technical Field

[0001] The present invention belongs to the technical field of hole exploration, and particularly relates to a peeping instrument probe fixing device with an adaptive drilling shape and a using method thereof. Background Technique

[0002] Field observation is an important means to obtain internal information of the surrounding rock of the working face, and borehole peeping is a commonly used and effective method among them. By drilling holes in the area to be detected and peeping, the attitude of the rock discontinuity surface, the development of internal fractures, geological structures such as faults, etc. can be obtained, which helps researchers understand important information such as the geological structure inside the borehole and the stability of the surrounding rock.

[0003] The camera of the borehole peeping instrument is usually located directly in front of the peeping probe, and records images and videos within its visible range. For the borehole peeping video, in essence, it is the video saved by the camera of the borehole peeping instrument probe during the entire process of the borehole peeping probe advancing in the borehole. Therefore, each frame in the video contains the information of the borehole wall that can be captured at the position where the borehole peeping instrument peeping probe is located at that time. However, when the surrounding rock of the borehole is broken or passes through geological structures such as faults and folds, resulting in borehole deformation, the borehole peeping probe cannot remain stable, and it is impossible to effectively obtain the borehole wall image, which affects the borehole peeping effect. In severe cases, the probe may be damaged, delaying the progress of the borehole peeping operation.

[0004] To solve the above problems, in the prior art, the application number 202311780836.3 discloses a bendable borehole peeping instrument probe fixing device and a using method thereof. In this design, one end of the camera rod of the peeping instrument is connected to the probe stabilizing mechanism, and sliding holes are arranged on the probe stabilizing mechanism. The advancement of the probe is controlled by the compression spring between the inner shell and the outer shell of the probe stabilizing mechanism and the rubber wheels on the outer shell, realizing the detection of non-straight boreholes. However, since the peeping instrument probe is fixed at the center of the probe fixing device by locking screws, when the shape of the borehole changes, the distance between the probe and the borehole wall will be changed, resulting in the inability to effectively obtain the borehole wall image and affecting the borehole peeping effect.
