Description

technical field

[0001] The invention relates to an underwater sampling tool, in particular to a water-air mixture and underwater planktonic microorganism sampler suitable for investigation of deep-sea mineral resources and biological resources, deep-sea environmental monitoring and polar exploration. Background technique

[0002] The sampling mechanism of the underwater sampler can be roughly divided into three categories: one is to rely on the gravity of the sampler to rush into the underwater sediment layer. When the sampler is flushed into the sediment layer, the hydrate in the sampler cavity is compressed, and the hydrate flows out from the pressure relief valve of the sampler. When the pressure in the cavity is lower than the threshold of the relief valve, the relief valve closes. Lift the sampler, the sediment in the sampler slides down, and a vacuum appears in the sampler cavity. Use this vacuum to absorb the sediment layer and part of the water-air mixture. [000...
