Abstract

The invention relates to a multifunctional protector of an underground probe of a hole drilling television image maker. The multifunctional protector comprises a sediment tube, a sealing ring, an upper joint, a disk-shaped clamping ring, a lower joint, a transparent casing tube, a bottom fixing head, and a probe sediment tube with a clamping groove. The multifunctional protector is characterized in that the sediment tube is connected with the upper joint together, the disk-shaped clamping ring is arranged between the upper joint and the lower joint, the lower joint is connected with the transparent casing tube together, the other end of the transparent casing tube is fixed with the bottom fixing head together, the probe sediment tube with the clamping groove is placed in a structure, the structure is formed by connecting the sediment tube, the upper joint, the lower joint, the transparent casing tube and the bottom fixing head, the clamping groove is clamped by the disk-shaped clamping ring, and the probe sediment tube and the lower end of the sediment tube are sealed by using the sealing ring. The multifunctional protector has the characteristics of low manufacture cost, high economic benefit, convenience for use, convenience for carrying and the like, can ensure the safety of the underground probe, and has the functions of improving the accuracy and the definition of probe imaging, and the like.

Description

technical field [0001] The invention belongs to the field of engineering geological survey and relates to a multifunctional protector for downhole probes of a borehole television imager. Background technique [0002] In the process of engineering geological survey, borehole TV imager logging, as an auxiliary survey method, has been paid more and more attention. It collects the panoramic image of the borehole wall through the camera in the downhole probe, which makes up for the fact that the geologists cannot accurately obtain the lithology, dissolution degree, and fracture development of the formation due to the poor coring during the drilling process of the drilling rig. , Structural development and other information is insufficient. During the logging process of the borehole TV imager, due to the complex geological conditions of the rock strata, rocks and gravels often fall off the hole wall. huge loss. Contents of the invention [0003] The purpose of the present inv...
