A detachable and easy-to-combine water quality sampling bucket

Abstract

The invention discloses a detachable water sampling bucket easy to assemble. The detachable water sampling bucket easy to assemble comprises an upper water-body sealing assembly, a bucket body, a lower water-body sealing assembly and a lifting handle. The upper water-body sealing assembly comprises an upper cover, an upper water sealing piece, an upper stainless steel circular ring, four Z-shaped limiting pieces, two L-shaped lifting lugs and four supporting rods; the lower water-body sealing assembly comprises a lower cover, a lower water sealing piece and a lower stainless steel circular ring. Sewage precipitating annular grooves and lower annular bucket inserting grooves are formed in the upper end face of the lower cover respectively, and upper annular bucket inserting grooves are formed in the lower end face of a cylinder of the upper cover. The upper stainless steel circular ring, the upper cover, the bucket body, the lower cover and the lower stainless steel circular ring are integrally connected with nuts in a fastened mode through the four supporting rods. The detachable water sampling bucket easy to assemble is simple in structure, rapidly convenient to assemble and disassemble, convenient to use and easy to clean.

Description

technical field [0001] The invention relates to a water quality sampler, in particular to a detachable and easily combined water quality sampling barrel. Background technique [0002] The material that generally uses water quality sampling bucket now is plexiglass, stainless steel and polypropylene resin material etc. Because its structure is bonded or welded, the upper and lower openings of the sampling barrel are very small, which is extremely difficult to scrub, and acid solution cannot be used for cleaning. The impurities accumulated in the barrel will directly pollute the collected samples after long-term reproduction. [0003] Although plexiglass has a good temperature application range (-50~60°C), strong hardness, good weather resistance, aging resistance and relatively stable chemical properties. However, a large amount of organic solvents such as acetone and chloroform are used in the manufacture of sampling barrels made of plexiglass. Under the influence of the co...

AI Technical Summary

Problems solved by technology

However, a large amount of organic solvents such as acetone and chloroform are used in the manufacture of sampling barrels made of plexiglass. Under the influence of the collected complex water bodies, a small amount of organic substances will dissolve into the collected water from the bonding part of the barrel. In the sample, it affects the analysis and detection of organic substances

[0004] The samples collected by the stainless steel sampler will be affected by the material of the container, resulting in the increase of metal substances in the sample, and it is not easy to scrub or soak in acid solution. After long-term use, the sample will oxidize and corrode the welding part of the cylinder. can also contaminate the sample quality

Although some samplers use a combination of screw buckles, rubber rings are used as seals on the screw buckle parts, and there is also the problem that the dissolution of organic substances affects the quality of samples.
