Marine environment monitoring device

Abstract

The invention discloses a marine environment monitoring device. The device comprises a take-up and pay-off mechanism and a sampling mechanism, wherein the take-up and pay-off mechanism comprises a support plate, a wire wheel and a mooring rope, the sampling mechanism comprises a shell, a sampling barrel and a floating seat, the sampling barrel is slidably connected into the shell, and a sampling hole is formed in a side plate of the sampling barrel. in the using process, when the sampling mechanism reaches the target depth, the shell descends under the action of gravity, so the sampling barrel performs sampling operation after reaching the target depth, and after sampling is completed, the floating seat ascends to close the sampling opening, and then the sampling mechanism ascends through the retracting and releasing mechanism, so water sample collection is accurately performed on a water body at the target depth; the collected water sample is accurate, so the water quality of the water body at the target depth can be accurately analyzed.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a marine environment monitoring device. Background technique [0002] The ocean is the general term for the most extensive water body on the earth. It refers to the vast waters on the surface of the earth separated by the continents. The central part of the ocean is called the ocean, and the edge part is called the sea. They communicate with each other to form a unified water body. [0003] Ocean water quality affects the reproduction and growth of marine organisms, thereby affecting the diversity of marine organisms. In recent years, ocean waters have been continuously damaged by human activities. Therefore, water quality needs to be controlled, and water quality monitoring is a prerequisite for ocean governance. and necessary conditions. [0004] For water quality monitoring, it is first necessary to sample water bodies at different depths in the ocean. The sa...

Problems solved by technology

[0004] For water quality monitoring, it is first necessary to sample water bodies at different depths in the ocean. The sampling device in the prior art is easy to collect water samples other than the water body at the target depth when sampling, so that the water body at the predetermined depth cannot be accurately sampled.
