SAMPLING INSTRUMENT Russian patent published in 2009 - IPC G01N1/10 

FIELD: mechanics.

SUBSTANCE: proposed sampling instrument comprises components of control and discharge and a system of intake pipes. The length of pipes is selected subject to sampling levels, while their amount is defined by the number of sampling points. Aforesaid intake pipes are fixed in the bracket vertically and in parallel to each other. There are flexible pipes tightly connected, by their one ends, with the lower ends of the aforesaid pipes and, by their other ends, connected to appropriate unions fitted in holes. Note that the holes are arranged in a passage element representing a disk. The proposed sampling instrument incorporates additionally a positioning shaft furnished with a bend arranged eccentrically at right angle to the shaft rotation axis. The shaft bend features a ledge representing truncated cone arranged at the bend end and at right angle to it. The shaft has a though inner bore with its outlet connected to the drain pipe. Note that the shaft ledge truncated cone features the shape and sizes corresponding to those of their receiving seats arranged on the passage element opening outlet. Aforesaid passage element is arranged in the reservoir hatch furnished with a hole through which the positioning shaft cylindrical part is passed. The shaft circular part tightly abuts upon the hatch inner side and is connected to aforesaid disk along its edges to form a rigid frame. The shaft horizontal part located in the said frame accommodates a spring to lock the ledge truncated cone in its seat.

EFFECT: higher reliability, ease of sampling.
