Seawater sampling detection device based on ocean thermocline

Abstract

The invention discloses a seawater sampling detection device based on an ocean thermocline, and relates to the technical field of seawater sampling, the seawater sampling detection device comprises a propelling box, a water baffle, a fixing plate and a supporting plate are sequentially and fixedly mounted in the propelling box from top to bottom, and a sampling groove is formed in the bottom of the supporting plate. According to the seawater sampling detection device based on the ocean thermocline, a sampling exchange mechanism is arranged, a driving motor is used for driving a driving rotating shaft to rotate, and a limiting column outside an upper center wheel and a limiting groove of a cross wheel are matched for rotation, so that intermittent rotation of a supporting rotating shaft is driven; meanwhile, clamping connection between a clamping rod and a supporting column is achieved through a first air cylinder, so that in the one-time deep sampling process, sampling at different depths can be achieved, repeated sampling operation can be avoided, meanwhile, position deviation can be avoided in the sampling process, and therefore the efficiency of the sampling process is improved; and the hindrance of length limitation of a rope or a pipeline is abandoned.

Description

technical field [0001] The invention relates to the technical field of seawater sampling, in particular to a seawater sampling detection device based on an ocean thermocline. Background technique [0002] Seawater thermocline refers to a step-like water layer in which seawater temperature changes sharply or discontinuously with depth; thermoclines are ubiquitous in the ocean, ranging from surface water of several meters and tens of meters to hundreds of meters and thousands of meters. Thermoclines exist in deep water. The strength, thickness and distribution of the thermocline are very complex. The seawater chemical elements such as seawater density, temperature, dissolved oxygen, pH value and salinity in the thermocline change drastically, and the thermocline is highly corrosive to equipment. It is easy to cause damage to some offshore work equipment. [0003] With reference to the Chinese patent, the patent name is: a seawater automatic sampling device (patent publicatio...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides a seawater sampling and detection device based on the ocean thermocline, which solves the problem that the existing sampling device cannot go deep into a certain depth during the sampling process, and different depths The sampling needs to be extracted reciprocally. At the same time, it will be easily mixed with seawater of different depths during the extraction process, resulting in slow sampling efficiency and inaccurate numerical accuracy.
