Pressure type water sampler for ocean detection

Abstract

The invention relates to the technical field of ocean water sampling detection equipment, and discloses a pressure type water sampler for ocean detection, which comprises a water sampling cylinder body, one side of the top end of the water sampling cylinder body is provided with a one-way gas injection valve communicated with the inside of the water sampling cylinder body, and one side of the top of the inner cavity of the water sampling cylinder body is provided with an exhaust pipeline communicated with the outside of the water sampling cylinder body. A pressure-bearing ball I is fixedly mounted at the top end of the exhaust pipeline, and a water inlet pipeline communicated with the outside is arranged on one side of the bottom of the inner cavity of the water sampling barrel. According to the pressure type water sampler for ocean detection, a plugging piston is limited, and the plugging piston is driven to overcome the elastic force of a reset spring to move upwards through the buoyancy of a buoyancy piston and the pulling force of a traction rope; and according to the water sampler, the water inlet pipeline can be effectively blocked, so that the phenomenon that seawater collected in the water sampler leaks or the problem that the seawater is polluted by seawater at other depths is avoided, and the stability and the reliability of the water sampler in the using process are effectively improved.

Description

technical field [0001] The invention relates to the technical field of marine water collection detection equipment, in particular to a pressure type water collection device for marine detection. Background technique [0002] Marine environmental monitoring is an important part of the earth's environmental protection, and the analysis of seawater composition is an important part of marine environmental monitoring. Due to light, pressure and other reasons, the composition and content of plankton and inorganic substances in seawater at different depths are different, so , It is necessary to collect seawater at different depths for experimental analysis, so as to make accurate analysis and judgment on the distribution of plankton and inorganic components in the ocean. [0003] At present, when the existing seawater collector is lowered into the sea, the cover needs to be opened first, and after reaching the specified seawater depth, the lid of the water collection bottle is clos...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides a pressure-type water collector for marine detection, which can be opened at a fixed point according to the depth of collection required, so that the collected seawater will not be affected by seawater at other depths, and is useful for detection and analysis. The results have the advantages of high accuracy, high stability and reliability, which solves the problem that the existing seawater collector needs to open the cover first when it is lowered into the sea, and hit it with a heavy hammer after reaching the specified seawater depth. method to close the lid of the water collection bottle. This type of water collection device will come into contact with seawater at different depths during the lowering process. It is inevitable that plankton or other elements will adhere to the inside of the water collection bottle, resulting in the collection of seawater. It will be affected by seawater at different depths, resulting in large errors and low precision in the analysis results, and it is difficult to make accurate analysis and judgment on the distribution of plankton and inorganic components in the ocean.
