Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1~2, in the utility model embodiment, a kind of vertical multi-point sampling device of ballast water, including some phases
Water storage cylinder 2 that is same, arranging and be welded and fixed up and down, the water storage cylinder 2 is cylindrical tube, and its bottom sets thief hatch 21, institute
Thief hatch 21 is stated with being connected in cylinder, hemispherical groove is set in thief hatch 21, the side relative with groove sets valve ball 8, institute
State and the first stage clip 9 is fixedly connected between valve ball 8 and the inwall of water storage cylinder 2, the coefficient of elasticity k of the first stage clip 9 meets k ＜ pgh π r2(its
In, p：Density of sea water, g=9.8kg/N, h：Ballast water is apart from the depth of the water surface, r：The radius of valve ball), i.e. the bullet of the first stage clip 9
Power is less than residing for the thief hatch 21 that valve ball 8 can backward be pushed up and opened to the pressure of valve ball 8, then hydraulic pressure by hydraulic pressure at the depth of water, makes thief hatch
21 open, and such ballast water just pours into water storage cylinder 2 automatically, after device is entirely put into ballast tank, due to different storages
