1. A system for a deep-sea planktonic microorganism in-situ concentration, temperature maintaining and pressure maintaining sampling, comprising:
a sampling cylinder body with double layer structures, wherein a bottom of the sampling cylinder body is provided with a sampling water outlet;
a plug-shaped body, fixedly disposed in the sampling cylinder body, wherein the plug-shaped body is defined with a plug-shaped inner cavity, a top of the plug-shaped body is provided with a transfer water outlet and a water inlet;
a water inlet assembly, connected to the water inlet;
an end cover, fixedly connected to the top of the plug-shaped body, wherein the end cover is provided with two through holes, and the two through holes respectively correspond to the transfer water outlet and the water inlet;
a filter part, fixedly connected to the plug-shaped body;
a pressure maintaining device, connected to the sampling water outlet; and
a water outlet pipe, connected to the sampling water outlet;
wherein a temperature maintaining material layer and a temperature control component are fixedly connected between the double layer structures of the sampling cylinder body, and the temperature control component is electrically connected to a controller.
