The invention solves the defects in the background technology, and has the following beneficial effects:
(1) the main material of the sampling device is made of the plastic film material, so that disposable consumables of the sampling material are formed, and the sampling material is not reused to prevent cross contamination. The quality of the plastic film material is light, when sampling, the sampling plastic film bag is connected with the cable and the counterweight, the pump pipe is connected to the pump body of the cable, and then the sampling plastic film bag is placed in the sea for sampling. The whole process can be operated by one person.
(2) The plastic film tube with the elastic rubber band is arranged, so that a pinch effect on the sample plastic film bag can be formed; and simultaneously, after the pump body is used for filling seawater into the plastic film tube, the plastic film tube is stretched and tightly stretched to form a spiral tube which is made into a spiral structure, so that the sample plastic film bag is gradually stretched through the hard and tightly stretched plastic film tube, the one-way ball valve at the inlet end of the sample plastic film bag is opened, and the seawater enters the sample plastic film bag to be sampled.
(3) After the pump body fills water into the plastic film tube, the sample plastic film bag is gradually filled with seawater, then the pump body stops working, so that the seawater in the plastic film tube flows out, the plastic film bag loses the tight support of the seawater, and the elastic rubber band is added to pinch the sample plastic film bag, so that the seawater passes through the one-way ball valve of the separation blade and then flows out from the one-way ball valve at the outlet end. In the process of flowing out of the seawater, the solid content in the seawater is retained in the filter cavity by the filter layer. The water filling and stopping of the pump body are repeated, so that the sample plastic film bag can continuously feed water and drain water, and the filter layer can filter enough seawater solid content for sampling.
(4) The filter chamber and the seawater chamber can respectively store seawater solid content and original seawater, and the partition plate has a separation effect to ensure that two samples can be taken by the same sampling device at the same time.
(5) The one-way valve uses the elastic deformation function of the rubber ball, and the rubber ball can be sealed on the detail of the pipe orifice under the proper extrusion action of the spring. When the force of seawater squeezing the rubber ball is larger than the elastic force of the spring, the rubber ball is opened, and the seawater can naturally flow.
(6) The cable can be lowered to the required depth through the cable laying and the sinking action of the counterweight.
(7) The plastic film tube with the spiral structure is wound on the periphery of the sample plastic film bag, the spiral structure simultaneously has the pinching force along the spiral axis and the radial two directions when pinching, and the sample plastic film bag expansion force opposite to the pinching force also follows the spiral axis and the radial two directions in the same way. Thus, the sample plastic film bag has good lumen pinching and expanding force.

After the pump body fills water into the plastic film pipe 13, the sample plastic film bag 1 is gradually filled with seawater, then the pump body stops working, so that the seawater in the plastic film pipe 13 flows out, the plastic film bag loses the tight support of the seawater, and the elastic rubber band 14 is added to pinch the sample plastic film bag 1, so that the seawater passes through the one-way ball valve 8 of the separation blade 3 and then flows out from the one-way ball valve 8 of the outlet end 4. During the outflow process of the seawater, the solid content in the seawater is retained in the filter chamber 6 by the filter layer 5. The water filling and stopping of the pump body are repeated, so that the sample plastic film bag 1 can continuously feed water and discharge water, and the filter layer 5 can filter enough seawater solid content for sampling.
