Anti-freezing device for water coupling probe in hole in alpine region

Abstract

The invention discloses an anti-freezing device for a water coupling probe in a hole in an alpine region. The anti-freezing device comprises a probe, wherein the probe is arranged in a capsule, and the capsule is connected and sealed with a capsule cover through a capsule fixing ring; an electronic thermometer and an electric heating wire are arranged below the capsule cover, and the electronic thermometer is connected with a ground temperature controller through a cable; and the ground temperature controller monitors the temperature of the upper part of capsule water through the electronic thermometer and heats the electric heating wire. In the cold region, the anti-freezing device for the water coupling probe in the hole is adopted, so that a geophysical prospecting probe is effectivelyprotected from frostbite, and normal work of the probe can be carried out in a cold time period.

Description

technical field [0001] The invention relates to the technical field of geophysical exploration, in particular to an antifreeze device for coupling probes with water in holes in alpine regions. Background technique [0002] There are many projects that use boreholes for testing in engineering surveys, but because many boreholes have leakage and there is no liquid medium such as water in the holes, many boreholes or hole sections are often unable to carry out acoustic testing work due to leakage and lack of water, thus losing Opportunity to obtain borehole acoustic data. [0003] In the prior art, an invention patent (publication number CN106199723A) applied by China Power Construction Group Guiyang Survey and Design Research Institute Co., Ltd. discloses a dry hole acoustic wave water coupling test device, including an acoustic wave transmitting probe and two acoustic wave receiving probes , the sound wave transmitting probe and the two sound wave receiving probes are connec...

AI Technical Summary

Problems solved by technology

[0004] However, the geophysical probe tests used in the above prior art holes do not take into account the antifreeze

In the cold area below 0 ℃, many construction projects cannot be stopped, and the geophysical survey work in the hole cannot be avoided

Geophysical testing is carried out in a water-coupled hole. The water temperature is generally greater than 0°C. When the probe leaves the water surface and enters the air below 0°C, it will quickly cool and freeze, which often causes damage, damage or failure to work for the geophysical probe.
