Description

Technical Field

[0001] The utility model relates to the technical field of measurement auxiliary devices, in particular to an underground borehole peeping auxiliary stabilizing device. Background Technique

[0002] The underground mine borehole imaging trajectory detection device is a high-tech device for comprehensively detecting boreholes. The product integrates functions such as borehole photographing, peeping (recording), imaging, and trajectory measurement. With one test, it can complete the workload of the previous four tests. At the same time, it can obtain dynamic video of the borehole, local high-definition photos, unfolded plan of the whole borehole wall, and borehole space trajectory, which is efficient and fast. The instrument takes a low-power embedded dual-core processor as the core, is equipped with a high-definition and high-line-number camera and military-grade high-precision spatial angle measurement devices, and is supplemented by software systems such as advanced control algorithms and image processing algorithms to synchronously realize all functions. It is used for detecting coal mine roof geological structures, coal seam occurrences, faults in front of the working face, water-conducting fissure zones in overlying strata, etc. It is suitable for detecting boreholes of various shapes and functions, such as horizontal holes, vertical holes, inclined holes, etc.; such as bolt and cable holes, gas drainage holes, drainage holes, and geological exploration holes.

[0003] The borehole imaging trajectory detection device has both the functions of a borehole peeping instrument and an imager, and at the same time has the function of borehole trajectory measurement. It can not only directly observe and record dynamic pictures such as water flow in the borehole in real time, but also image the whole borehole wall in the borehole and unfold it into a plan view. Moreover, it can generate a virtual core three-dimensional columnar diagram, which can vividly and intuitively reproduce the internal structure of the hole and conduct quantitative analysis. It can effectively detect the occurrence, thickness and other occurrence conditions of coal seams, and guide the rational and scientific organization of production; through periodic comparative observation and imaging of the same borehole, it can reveal the development and deformation of joints, faults and fissures in the surrounding rock of the coal seam roadway, predict the development trends of potential disasters such as roof separation and caving, roadway instability, etc. in the roadway, provide reference for taking scientific and effective preventive measures, and reduce mining risks and production costs; it can evaluate the effectiveness of roadway support design, surrounding rock grouting reinforcement and roadway repair, etc. and provide true and effective technical basis to improve the safety of underground coal mine production.

[0004] The borehole is an upward hole underground, and the heights of the holes are uneven. How to smoothly send the detection instrument into the hole and carry out peeping work is one of the difficulties in borehole peeping detection. Usually, the staff manually connects the push rod and sends the push rod into the hole by manpower. As the number of rods increases, the manpower is greatly consumed. Especially when there is water in the hole, it is necessary to hold the push rod by hand, which further exacerbates the physical consumption. Summary of the Invention
