Manual simple columnar sediment collection device and method thereof

Abstract

The invention discloses a manual simple columnar sediment collection device and method thereof, comprising a sampling pipe, a gas path control pipe, a first connecting rod and a second connecting rod,wherein the sampling pipe comprises a sampling cylinder, a reducer union, a first connecting pipe, a first external thread movable joint, a gas path steel pipe, a gas hose, a steel pipe plug, a sampling pipe internal thread plug, a sampling pipe smooth plug and an inflator; the gas path control pipe comprises a four-way pipe, a second connecting pipe, a third connecting pipe, a fourth connectingpipe, a fifth connecting pipe, a sixth connecting pipe, a seventh connecting pipe, a check valve, a first ball valve, a second external thread movable joint, a first internal thread movable joint, a gas path control pipe plug and a gas nozzle, wherein the first internal thread movable joint at the lower end of the gas path control pipe is connected with the first external thread movable joint at the upper end of the sampling pipe; and the first connecting rod and the second connecting rod are sequentially connected and fixed at the upper end of the gas path control pipe. The invention can greatly improve the sampling efficiency, improve the carrying convenience of the sampler, reduce the manufacturing cost of the sampler and reduce the sampling risk.

Description

Technical field [0001] The invention belongs to the field of sediment collection, and specifically relates to a manual columnar sediment collection device and a method thereof. Background technique [0002] Sediment mainly refers to the solid matter that enters the water body in various forms and is finally deposited on the bottom of the water body under the action of flocculation and gravity. The study of underwater sediments on rivers and hydrology, biodiversity research, environmental monitoring, water body protection, etc. Has an important role. [0003] Traditional sediment collectors, on the one hand, are of high quality, are not convenient to carry in the field, and have low collection efficiency; on the other hand, they are expensive, cumbersome to operate, and costly to collect, which is not conducive to large-scale promotion. In addition, traditional manual sediment samplers are difficult to collect deep dense sediments, and sample collection is limited by the deposition...
