Description

technical field [0001] The invention is a high-precision submarine geothermal flow detection device, which belongs to the innovative technology of a high-precision grating ruler fast measuring device and a measuring method thereof. Background technique [0002] In marine geological surveying, it is often necessary to obtain high-precision seabed temperature, geothermal gradient, and thermal conductivity data on the seabed, and calculate them into high-precision terrestrial heat flow data, so as to study the fineness of the geothermal field of special geological bodies on the seabed such as seabed cold springs and hydrothermal vents. Information provides technical support. [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 seafloor heat flow has the disadvantage...

Problems solved by technology

Since the detection equipment of the present invention is in the off-line working environment of the deep seabed, the battery is generally used as the energy supply mode. After a period of use, the instrument compartment needs to be opened to charge or replace the battery. Carry out high-pressure watertight test, which is very prone to problems, resulting in damage to the equipment during use

Another problem brought about by the offline working method is that the data must be read and analyzed after the equipment is recovered, and real-time in-situ measurement and analysis cannot be performed. If a cable connection is used, the range of movement and usage of the equipment are greatly limited; because the use environment is in The pressure of seawater on the bottom of the ocean makes the interface processing of cables very complicated and difficult; when measuring thermal conductivity parameters, it is necessary to use the thermal pulse impact method, and the off-line method is difficult to control the timing of thermal pulse generation, and it is impossible to realize the thermal conductivity parameters of the seabed geothermal flow field The in-situ measurement of the equipment; when using the equipment, it is generally controlled by a remote control manipulator or an underwater robot. The existing equipment does not have a corresponding indicator mark, so it is difficult to judge whether the equipment is in the vertical direction. Correction of gradient data cannot well meet the requirements of scientific research work
