Seawater sampling and detecting device

Abstract

The invention discloses a seawater sampling and detecting device, comprising a movable base, a main body frame and a sampling unit, wherein the main body frame is fixedly connected with the movable base through an adjustment bracket; a fixed seat is arranged on the surface of the adjustment bracket; the surface of the fixed seat is loaded with a charging barrel; a dual detecting unit is installedon the side surface of the charging barrel; the movable base is fixed by a positioning frame located at the bottom; the main body frame comprises a central column and an electric push rod; one end ofthe electric push rod is mounted on one end of the central column through a metal seat, and the other end of the electric push rod is connected with a sliding seat sleeved on the surface of the central column; a fixed plate is connected with one side of the sliding seat and is fixedly connected with the sampling unit; and the sampling unit is fixed by an anti-shake unit. The whole seawater sampling and detecting device can rapidly sample and detect seawater from different regions and at different depths, is hardly to shake and more stable during sampling, can be quickly cleaned after detectionand avoids generation of residues or corrosion.

Description

technical field [0001] The invention relates to the technical field of seawater detection, in particular to an integrated device for sampling and detecting water body salinity based on ocean osmotic energy. Background technique [0002] Seawater power generation method is mainly "infiltration method". The so-called "infiltration method" is to use pressurization method to accelerate the seawater infiltration process. In the demonstration experiment, after the scientists used a special membrane to separate the seawater from the pure water in the container, the pressure on the seawater side of the membrane would be higher than that of the pure water side. As a result, part of the pure water will flow out of the tank through the membrane, and generate a huge power that can drive the water motor to generate electricity. In osmotic power generation technology, the manufacture of thin film is the most important. A qualified film must have good water permeability, durability, and...

AI Technical Summary

Problems solved by technology

[0005] (1) The traditional seawater salinity detection device cannot sample seawater in different regions and depths at the same time when sampling seawater, which leads to deviations in seawater salinity detection and cannot accurately understand seawater salinity Spend;

[0006] (2) After the general seawater salinity detection device detects different seawater, there will be seawater residues in different degrees inside the container used to store seawater, which will not only affect the next seawater detection, but also have a negative impact on the container itself. Corrosion, affecting service life;

[0007] (3) When sampling and testing seawater, sometimes the wave of seawater will shake the device itself, which will affect the smooth progress of sampling. At the same time, the shaking of the device will easily lead to loose connection of the device structure, which is not conducive to the long-term use of the whole device
