Equipment for sampling water bodies above seabed at fixed distance

Abstract

The invention discloses equipment for sampling water bodies above the seabed at a fixed distance, aiming to provide equipment for sampling water bodies above the seabed at a fixed distance, which can be used for conveniently and accurately collecting water samples in specific distances above the seabed. The equipment comprises a triggering device, a settling balance weight, a triggering balance weight, a plurality of water sample collectors and a winch, wherein the winch is arranged on a hull; the triggering device comprises a vertical triggering cylinder, an upper piston body, a lower piston body, a first connecting rod, a second connecting rod and buoyancy devices; the upper and lower piston bodies are arranged in the triggering cylinder in a sliding manner; the first connecting rod is used for connecting the upper and lower piston bodies; the second connecting rod is arranged in the middle of the lower end face of the lower piston body; the buoyancy devices are arranged at the outer sides of the triggering cylinder.

Description

technical field [0001] The invention relates to a water sampling device, in particular to a fixed-distance sampling device for seabed water body. Background technique [0002] Water sample collection is an important part of water environment scientific research and water environment protection and management. The collection of water samples at different depths is the premise and basis for the smooth development of various research work. The water body in the water area is affected by factors such as material, water flow, and temperature, and there will be a stratification effect. The hydrological, physical, chemical, and biological information of different water layers is different. Collecting and analyzing the differences in water bodies at different layers is a key step in environmental science and marine science. It is widely used in practical fields such as water ecological environment assessment and pollution accident investigation. [0003] Most of the current water c...
