High-precision seabed geothermal gradient detection device

Abstract

The invention provides a high-precision seabed geothermal gradient detection device used for detecting seabed surface-layer geotherm parameters. The high-precision seabed geothermal gradient detection device comprises a pressure protection pipe, a thermal insulation rod, an insulator, a two-color LED, an electronic instrument cabin shell, a charging induction coil and a plurality of thermistors, wherein a cavity of the electronic instrument cabin shell is an electronic instrument cabin. The insulator is installed on one side of the electronic instrument cabin, the pressure protection pipe is supported by the insulator, the thermal insulation rod is installed in the pressure protection pipe, and the thermistors are installed on the thermal insulation rod. A three-axis acceleration sensor is installed in the electronic instrument cabin, the two-color LED and the charging induction coil are installed outside the electronic instrument cabin, a transparent protection cover is installed outside the two-color LED and the charging induction coil, and the two-color LED, the charging induction coil, the thermistors and the three-axis acceleration sensor are connected with a control device through conducting wires, wherein the control device is installed in the electronic instrument cabin. Variation of the angle of inclination of the device is indicated through the two-color LED, operation is facilitated, and data acquisition efficiency is improved.

Description

technical field [0001] The invention is a detection device capable of carrying out high-precision seabed geothermal gradient measurement, which belongs to the innovative technology of high-precision seabed geothermal gradient detection equipment. Background technique [0002] In marine geological surveying, it is often necessary to obtain high-precision geothermal gradient data in the vertical direction of the seabed to form relevant high-precision geothermal field data, so as to cooperate with other physical parameters to carry out the mineralization mechanism, mineralization characteristics, accumulation dynamics, and enrichment of related minerals. Regularity and reserve estimation and other research work. [0003] Conventional seabed heat flow detection equipment (including geothermal gradient detection equipment and geothermal probes) is used to detect seafloor heat flow in deep sea areas through survey ships and ship-borne winches. This method of in-situ detection of s...

Problems solved by technology

Due to the impossibility of high-pressure watertight test at the work site, problems are prone to occur, resulting in damage to the equipment during use

When the equipment is used in the deep seabed environment, it is generally controlled by a remote control manipulator or an underwater robot. If the equipment does not have a corresponding indicator mark, it is difficult to judge whether the equipment is in the vertical direction. The data is corrected and corrected, which affects the quality of the collected data and cannot well meet the requirements of scientific research work
