Embodiment Construction

[0027] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0028] like figure 1 As shown, a drop-in water collection system includes a trigger device 1, a trigger counterweight 112, a sinking counterweight 4, four water sample collectors 3 and a winch 5 arranged on the hull. The winch comprises a vehicle frame 51 arranged on the hull, a reel 53 which is rotatably arranged on the vehicle frame by an axle rod 52, a traction rope 54 wound on the reel and a drive which is arranged on the hull for driving the rotation of the reel. motor. The axle rod is rotatably arranged on the vehicle frame through bearings. The shaft is set horizontally. A gear reducer is arranged between the drive motor and the shaft.

[0029]The trigger device comprises a vertical trigger cylinder 11, an upper piston body 14 and a lower piston body 16 slidably arranged in the trigger cylinder, and a first connecting rod 12 connectin...

Abstract

The invention discloses a drop-type water body acquisition system and aims at providing a drop-type water body acquisition system capable of conveniently and accurately acquiring water samples in a specific distance above the seabed. The drop-type water body acquisition system comprises a trigger device, a trigger counterweight, a settling counterweight, multiple water sample acquirers, and a winch arranged on a ship body, wherein the trigger device comprises a vertical trigger cylinder body, and an upper piston body and a lower piston body which are glidingly arranged in the trigger cylinder body, and also comprises a first connecting rod connecting the upper and lower piston bodies, a second connecting rod arranged in the middle of the lower end surface of the lower piston body, and a buoyancy device arranged on the outer side surface of the trigger cylinder body.

Description

technical field [0001] The invention relates to a water collection device, in particular to a drop-in water body collection system. 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 collectors are ...
