Description

technical field

[0001] The invention relates to a collection device, in particular to a suction-type membrane filter suspended particle collector for marine environment monitoring for sampling suspended particles in seawater. Background technique

[0002] Suspended particles are an important manifestation of the nutritional structure of water ecosystems, and can reflect the potential change trend of water quality in a system, which mainly include suspended sediment, phytoplankton, zooplankton, and humus (organic debris). The suspended particulate matter in the water body of the aquaculture area is an important medium for various pollutants in the water body, and plays an important role in the migration and distribution of various pollutants in the aquatic ecosystem, and plays an important role in the bioavailability and Final destination has an important impact. With the deepening of people's research on suspended particulates in water bodies in aquaculture sea areas, sampl...

Embodiment Construction

[0043] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0044] Such as figure 1 As shown, a suction-type membrane filter suspended particle extractor for marine environment monitoring includes a frame, a water pump 37, a traction rope 39, a counterweight 41, a water pumping pipeline 38, and the first fixed on the frame A guide tube 1 and a second guide tube 15 can rotate a rotating shaft 18 arranged on the frame and two installation sleeves 8 uniformly distributed around the rotating shaft in the circumferential direction. The suction pipe is a metal hose or a rubber hose. One end of the suction pipe is connected with the water inlet of the water pump. The other end of the suction pipe is fixedly provided with a connecting ring 40 . The counterweight is connected with the connecting ring through the connecting rope. One end of the traction rope is connected with the connecting ring. One of the t...
