The structural stability problem of the rock mass engineering during construction and operation is the most concerned problem for rock mechanics workers, and the deformation characteristics and rules of the rock mass are directly reflected by judging whether the surrounding rock is in a safe and stable state. The key parts of rock deformation and damage are mostly located on discontinuous structural surfaces such as cracks, joints, bedding, faults and the like, and the structural surfaces are usually represented by geometrical characteristics of the structural surfaces, so the scientificity, advancement, integrity and accuracy of the acquisition technology, method and means of the geometrical characteristics of the structural surfaces are particularly important.
The drilling shooting technology is popular among field constructors and scientific researchers because the drilling shooting technology can visually reflect the cracking damage degree of the rock, can obtain information such as the cracking position, the occurrence state and the width of the wall surface of the drilled hole, and can calculate the deformation size and the deformation rule of the surrounding rock by analyzing the information of the wall surface of the drilled hole shot at different time.
Along with the increase of the buried depth of rock engineering, high ground stress disasters and high radioactive pollution become more serious, which causes great threat to the life safety of drilling detection workers. The method has great danger in the construction and test of the rock engineering, and the deformation and damage degree of the surrounding rock are observed by utilizing the conventional drilling and shooting in the environment, so the life safety of operators faces great threat. The existing drilling camera can only be suitable for detection of one aperture and cannot be suitable for drilling of multiple apertures. In addition, the current drilling camera shooting needs to continuously push the drilling camera shooting instrument into the drilling hole by using a plurality of connecting rods so as to obtain the information of the surrounding rock of the hole wall in the axis direction of the whole drilling hole, and large physical force and time need to be consumed. The common borehole camera can only be used for observing the geological phenomena in the borehole, and can not accurately calculate and analyze the geological phenomena (such as determining the attitude, the interval, the gap width and the like of a structural plane), and can not carry out deeper statistics and analysis.

Each turbine 63 is mounted on a turbine support base 67 via a turbine shaft 68 and a turbine fastening shaft 69. Turbine adjusting pieces 60 are further arranged on two sides of the turbine 63 on each turbine fastening shaft 69 respectively, so that the turbine 63 can be better installed, and the turbine 63 can be guaranteed to rotate normally. The outer wheel face of each turbine 63 is in contact with the top of the drive shaft 45 and the contact points of the three turbines 63 are on the same circumference. The center of the head vertical plate 61 is sleeved on the neck of the transmission shaft 45 in a penetrating way. The three turbine supporting seats 67 and the three first limiting shafts 74 are uniformly installed and sleeved on the head vertical plate 61 at intervals by taking the transmission shaft 45 as a circle center.
During actual work, the torque of the motor 44 is transmitted to the worm 64 through the transmission shaft 45 and then is transmitted to the driving wheel 41 through the turbine 63 and the gear 65; the driving wheel 41 rotates and generates friction with the inner wall of the drill pipe, which is the power for the walking of the device.

When monitoring is carried out in a drilling hole or a pipeline, corresponding reducing is needed to ensure the advancing of the device. Also contributing to the change is the first spring 76 and the second spring 86. When the device runs and meets an obstacle, after one or more driving wheels 41 contact the obstacle, the driving wheels 41 contract inwards and act on the first strut slide 72 through the driving connecting plate 62 and the first tensioning plate 71; the first spring 76 is extended, and is simultaneously and stably retracted inward by the three driving wheels 45; the above actions can meet the requirements of reducing and obstacle crossing. As the inner wall of the borehole tubing expands, the corresponding first spring 76 expands.
