In a preferred embodiment of the present invention, the sample plastic film bag is separated into filter chamber and seawater by the barrier piece
Chamber, the filter layer are arranged in the filter chamber.
The present invention solves defect present in background technology, and the present invention possesses following beneficial effect：
（1）The main material of sampling apparatus is made by using plastic film material, forms the medical disposable material of sampling material, sampling
Cross pollution can be prevented by not reusing afterwards.The quality of plastic film material is light and handy, in sampling, by sampling plastic film bag connection cable
And counterweight, pump line is connected on the pump housing of cable, is then placed in marine sampling.One is i.e. operable for whole process.
（2）By being provided with the plastic film tube of elastic rubber band, can be acted on the constriction of shape paired samples plastic film bag；Make simultaneously
After being filled with seawater into plastic film tube with the pump housing, plastic film tube be softened it is hard just form helical structure after stretching tight helix tube is made,
So can be so that gradually sample plastic film bag to be strutted by firmly taut plastic film tube, now single-direction balls of the entrance point of sample plastic film bag
Valve is just opened, and seawater just enters progress seawater sampling in sample plastic film bag.
（3）The pump housing after water-filling, is gradually filled with seawater into plastic film tube in sample plastic film bag, then the pump housing is stopped, and makes
Seawater outflow in plastic film tube, plastic film bag lose the support that seawater is tightened, the constriction plus elastic rubber band to sample plastic film bag, made
Seawater passes through the non-return valve of barrier piece and then flowed out from the non-return valve of the port of export.During seawater outflow, consolidating in seawater
Inclusion stays in filter chamber by filter layer.Water-filling and stopping by the pump housing, are repeated, and then make it that sample plastic film bag is continuous
Water inlet and draining, ensure that filter layer can filter the seawater Solid content enough to sampling.
（4）Filter chamber and seawater chamber can preserve seawater Solid content and former state seawater respectively, and separator sheets play compartmentation,
Ensure that same sampler can take two kinds of samples simultaneously.
（5）Check valve is acted on using the elastic deformation of ball, under the appropriate squeezing action of spring, can make ball
It is sealed in mouth of pipe thin portion.When the power of seawater extruding ball is more than the elastic force of spring, ball is not just opened, and seawater can be with
Naturally flow.
（6）Cable is acted on by the sinking of cable laying and counterweight, sample plastic film bag is descended to the depth of needs.
（7）The plastic film tube of spiral spiral structure is wrapped in sample plastic film bag periphery, and helical structure is provided simultaneously with constriction
Along spiral axial line and the constriction power of the both direction of radial direction, similarly the sample plastic film bag expansive force opposite with constriction power is also edge
Spiral axial line and radial direction both direction.So sample plastic film bag just possesses good inner chamber constriction and expansive force.
