Abstract

The invention discloses a trigger floating type water sampling device, and aims to provide a water sampling device capable of conveniently and accurately collecting a water sample in a specific distance above the seafloor. The device comprises a trigger device, a sedimentation counterweight, a trigger counterweight and a plurality of water sample collectors, wherein the trigger device comprises a trigger cylinder body which is vertically arranged, an upper piston body and a lower piston body which are arranged in the trigger cylinder body in a sliding manner, a first connecting rod which is connected with the upper and lower piston bodies, a second connecting rod arranged in the middle of the lower end face of the lower piston body, and a buoyancy device which is arranged on the outer face of the trigger cylinder body.

Description

technical field [0001] The invention relates to a water harvesting device, in particular to a triggered floating water harvesting device. 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 collector...
