Multifunctional auxiliary device suitable for panoramic borehole camera

Abstract

The invention discloses a multifunctional auxiliary device suitable for panoramic borehole camera. The multifunctional auxiliary device suitable for panoramic borehole camera comprises a probe protection housing, rolling wheels, springs, auxiliary mooring ropes and a probe advance protection device, wherein the radian of the inner wall of the probe protection housing fits to a panorama probe; theouter wall of the probe protection housing is connected with the rolling wheels through springs; triangular prism-frustum-shaped rolling wheel shells sleeve outside the rolling wheels; and the probe advance protection device comprises a long spring, a short spring, one-way rolling wheels, a spring clamping piece, spring steel sheets and a shell. According to the multifunctional auxiliary device suitable for panoramic borehole camera provided by the invention, a panoramic borehole camera instrument operator can be helped to judge the risks such as panoramic probe front hole diameter decrease and stones stuck in a hole in advance, and is assisted to recognize whether water exists in the hole or not and the water surface elevation in the borehole, the hole wall chippings are cleaned, the panorama probe is ensured to centrally detect stably in the hole and is prevented from falling and being damaged, and the borehole camera work is ensured to be safely and efficiently carried out.

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
