Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown in —12, the driving source assembly 39 is installed on the bracket 20 inside the suction cylinder 17 and locked, and the external piston spring compensator assembly 38 communicates with the inside of the DC motor casing 7 through the compensation oil pipe 5 to form a pressure compensation The mechanism protects the DC motor 10 . The suction hose 32 is connected to the through hole 36 on the lower cover plate 23 of the filter element base, and the through hole 37 on the upper cover plate 24 of the filter element base is connected to the suction cylinder cover plate 18; then the whole device is submerged in the water , when reaching the specified sampling position on the deep seabed, start the DC motor 10 through the cable 6, and the paddle 19 at the front end of the motor shaft rotates, and the rotation of the paddle 19 will d...

Abstract

The invention discloses a deep-sea biological suction multi-stage enrichment sampler, which comprises a suction drive source assembly, a suction cylinder assembly, a multi-stage combined filter element assembly and a suction pipe group. The suction cylinder assembly includes a bottom wall and an The upper cover cylinder is provided with a suction driving source through the bracket, and a through hole is opened on the bottom wall, and the closed multi-stage combined filter element assembly is connected through a connecting hose, and the external force acts on the gear on the multi-stage combined filter element assembly. The connecting rod can switch the filter element conveniently, and the lower cover plate of the multi-stage combined filter element assembly has a through hole to connect with the suction hose. There are 4 groups of filter installation diameters, and each stage of filter has different apertures. A large number of microbial samples can be realized in one dive operation; the gear connecting rod is used to drive the gear to realize the rotation of the filter element, the selection of the turntable to close or the switch of the filter diameter; different sampling can be realized Function and effect; simple structure, easy processing and manufacturing, low cost, high work efficiency; and can carry large-scale equipment such as deep-sea manned submersibles and remote-controlled unmanned submersibles.

Description

technical field [0001] The invention relates to a sampling device, especially capable of assisting large-scale deep-sea equipment to enrich and obtain microbial samples, including flocs and proteins, in deep-sea hydrothermal or cold seep areas. Background technique [0002] At present, the sampler specially aimed at obtaining deep-sea microorganisms is developing vigorously in the research of deep-sea equipment technology. In conventional marine survey equipment, gravity columns, visual grabs, and landers cannot meet the needs of obtaining deep-sea microbial samples. However, the conventional sampling devices carried by my country's most advanced deep-sea manned submersible "Jiaolong" include sampling manipulators. , sediment samplers, biological sample baskets, rock sample baskets, etc., although some geological or macrobiological samples with or containing microorganisms can be obtained, they cannot meet the basic needs of scientists for microbial research in terms of sampl...
