A Multifunctional Auxiliary Device Suitable for Panoramic Borehole Camera

Abstract

The invention discloses a multifunctional auxiliary device suitable for panoramic borehole photography, which includes a probe protective shell, rollers, springs, auxiliary cables, and a probe advance protection device; the curvature of the inner wall of the probe protective shell fits the panoramic probe, The outer wall of the probe protection shell is connected with the roller through the spring, and the roller shell is provided with a triangular prism-shaped roller shell. The probe advance protection device includes a long spring, a short spring, a one-way roller, a spring clamp, a spring steel sheet, and a shell; the invention can help The operator of the panoramic drilling camera equipment judges in advance the dangers such as the smaller aperture in front of the panoramic probe and the stone stuck in the hole, assists in identifying whether there is water in the hole and the height of the water surface in the borehole, cleans up the debris on the hole wall, and ensures that the panoramic probe is centered in the hole Stable detection, avoiding the fall and damage of the panoramic probe, ensuring safe and efficient drilling camera work.

Description

technical field [0001] The invention relates to a multifunctional auxiliary device suitable for panoramic drilling camera. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In recent years, the panoramic borehole camera technology, which puts the 360-degree panoramic probe into the engineering borehole to capture the image of the engineering borehole wall, has been widely used in engineering geological surveys in recent years. The panoramic borehole camera system includes a 360-degree conical mirror , in-hole light source, magnetic compass, and micro-camera, etc., through post-processing of the camera data, the expanded map of the borehole wall can be obtained, so as to obtain information such as stratum lithology, fracture distribution, and structural development. [0004] In the actual application of drilling panoramic drilling camera, especially ...

AI Technical Summary

Problems solved by technology

[0004] In the actual application of drilling panoramic drilling camera, especially when the geological conditions of the formation are poor, the quality of engineering drilling is not good, and the debris adhering to the hole wall affects the observation of the hole wall, and because the detection personnel It is impossible to judge in advance the shrinkage of the drilled hole in front of the probe and the stone stuck in the hole, which will cause the panoramic probe to be stuck in the hole and cannot be retracted or the instrument will be damaged;

[0005] Secondly, due to the heavy weight of the panoramic probe, it is easy to cause the probe to fall, causing huge economic losses and directly affecting the progress of the engineering survey;

[0006] In addition, the currently used panoramic probe cannot effectively identify the water content in the hole, and cannot ensure that the probe is centered and stable in the borehole without rotation (especially when detecting oblique boreholes), which affects the detection effect
