The problem of deposit overflows at the top of sampling pipe when sampling；
3）Due to installing a protection ring additional in support rod bottom section, even if it is thus ensured that this sampling apparatus is by stone impact
Also it can guarantee sampling pipe not crack damage, while also strengthening the stability of two sampling pipes；
4）It due to increasing removable cover, can either drain upwards, and can be adsorbed on and adopt during being lifted up
At sample pipe upper port, negative pressure is formed, during guaranteeing that sampler above mentions, deposit does not slide from sampling infratubal port；
5）Due to using stop collar, it can guarantee that the installation site of two probe tubes is in sustained height, guarantee
Parallel sample is more accurate；
6）Due to using clump weight, even if also guaranteeing that probe tube can be inserted perpendicularly into deposit in the water flow of movement
In, guarantee that sampling is more accurate；Meanwhile also clump weight impact protector ring can be driven by traction rope, so that sampling pipe is easier
It is inserted into harder deposit, increases sampling depth；
7）The lower end surface of protection ring uses inverted cone-shaped structure, is conducive to reduce sampling resistance；
8）Due to offering groove compatible with elastic seal ring on the surface of ring flange and/or the bottom surface of positioning sleeve,
It can be limited when elastic seal ring suffers oppression to deform outward, it is made inwardly to fasten sampling pipe, increased elastic seal ring and adopted
Frictional force between sample pipe keeps sampling more solid and reliable to clamp sampling pipe.
