Empennage-adjustable bottom sediment temperature detection device

Abstract

The invention discloses an empennage-adjustable bottom sediment temperature detection device, which comprises an empennage section, a control section and a probe section, wherein the empennage sectioncomprises an upper end cover, an empennage located outside the upper end cover, an empennage motor located inside the upper end cover to control the motion of the empennage, and an upper communication cable extending out of the top of the upper end cover; the control section comprises a sealed cabin and a floating body located outside the sealed cabin; a control mainboard, a motor driving plate,a communication mainboard and a battery pack are arranged inside the sealed cabin; the probe section comprises a lower end cover, a probe extending out of the lower end cover, and a lower communication cable located inside the probe; and the upper and lower ends of the sealed cabin are respectively connected with the upper end cover and the lower end cover. The temperature detection device disclosed by the invention can effectively correct a sinking posture of the probe by controlling the empennage, and can calculate a pouring point position and motion parameters of the whole pouring process to more effectively measure a deeper geothermal temperature gradient in a seabed.

Description

technical field [0001] The invention relates to the technical field of deep-sea detection, in particular to an adjustable empennage-type seabed sediment temperature detection device. Background technique [0002] The investigation of seabed heat flow is the preliminary work of seabed gas hydrate resource investigation. Seabed heat flow survey technology is usually used to measure seabed temperature and calculate geothermal gradient, so as to analyze the accumulation conditions of gas hydrate and invert the depth of the bottom boundary of gas hydrate stable layer. buried. Modern seabed temperature gradient and heat flow detection usually use probe technology, which has high precision and convenient operation, which is unmatched by other detection technologies. [0003] At present, there are mainly three kinds of temperature gradient and heat flow probe technologies that are widely used, and they are also products in three stages of development. They are Bullard type, Ewing t...
