Abstract

The invention discloses a trigger-type seabed water sample collection system, aiming to provide a trigger-type seabed water sample collection system capable of conveniently and accurately collecting water samples within a specific distance above the seabed. It includes a release device, a trigger device, a sinking weight and several water sample collectors. The water sample collector includes a third connecting rope, a collection tube with both ends closed, guiding through holes arranged at both ends of the collecting tube, a sliding shaft that can be slidably arranged in the guiding through hole, and a tube connected to the collecting tube through the fourth connecting rope. The limit ball, the unlocking device and the buoyancy body arranged on the collection cylinder, and the buoyancy of the buoyancy body is greater than the gravity of the water sample collector.

Description

technical field [0001] The invention relates to a water sample collection device, in particular to a trigger type seabed water sample collection system. Background technique [0002] Water body sampling 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 wate...
