Drill hole imager probe wiping device

Abstract

The invention discloses a drill hole imager probe wiping device which comprises a probe body, wherein a support plate is arranged on the probe body; an air cylinder parallel to the probe body is mounted on the support plate; the end part of an air cylinder rod of the air cylinder is fixedly connected with a wiping ring; and the wiping ring is made of a water-absorbing elastic material, and the inner side clings to the outer side surface of a transparent part of the probe body. In the invention, the extension / retraction of the air cylinder is controlled to drive the wiping ring of water-absorbing elastic material to wipe the transparent part of the probe, remote control of probe wiping is realized, time and labor are saved in the operation, the operation is more convenient, the image collection efficiency is increased, the image collection effect is greatly improved, and the problems of bad image collection effect, inconvenience in wiping, time and labor waste, bad image collection effect and low efficiency of the prior art are effectively solved; and the device disclosed by the invention also has the characteristics of simple structure, low cost and convenience and quickness in assembly / disassembly and use.

Description

technical field [0001] The invention relates to a probe wiping device of a borehole imager, and belongs to the technical field of borehole imagers. Background technique [0002] At present, the borehole imager is widely used in engineering geology, hydrogeology, geological prospecting, geotechnical engineering, mining and other departments; it is suitable for vertical holes, horizontal holes and inclined holes (depression angle, elevation angle). The core part of the borehole imager is the borehole probe to collect panoramic high-definition images. However, in engineering practice, when the imager collects deep hole images, it is often due to the large temperature difference between the outside and the inside of the hole, and the glass of the borehole probe shell is prone to water mist. The probe is blurred, which seriously affects the image acquisition and makes the acquired image blurred. Since the probe is in the deep hole and the water mist cannot be wiped off, it will ...

AI Technical Summary

Problems solved by technology

The core part of the borehole imager is the borehole probe to collect panoramic high-definition images. However, in engineering practice, when the imager collects deep-hole images, the glass of the borehole probe shell is prone to water mist due to the large temperature difference between the outside and inside of the hole. The probe is blurred, which seriously affects the image acquisition, making the acquired image blurred

Since the probe is in the deep hole, and the water mist cannot be wiped off, it will affect the image acquisition results of the lens. If it is taken out and wiped and then put in, it will be time-consuming and laborious, and the image acquisition efficiency will be greatly reduced.
