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; a rotation motor is mounted on the support plate; a steel wire winding wheel is mounted on an output shaft of the rotation motor; a flexible steel wire is wound on the steel wire winding wheel; the steel wire is parallel to the axis of the probe body, and a free end of the steel wire is fixedly connected with a wiping ring; 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; and a compression spring is mounted between the upper side surface of the wiping ring and the lower side surface of the support plate. In the invention, the rotation of the rotation motor is controlled to drive the steel wire winding wheel to rotate, the wiping ring of the water-absorbing elastic material is driven by the steel wire and the compression spring to wipe the transparent part of the probe back and forth, 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, and the image collection effect is greatly improved; 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 ...

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.
