Embodiment 1

[0025] The multi-layer depth sampling device for water environment monitoring described in this embodiment includes a cylindrical body 4 and a plurality of sampling bottles 3. The top of the cylindrical body 4 is connected with an outer sleeve 6 extending downward. An inner sleeve 7 is provided, the outer wall of the inner sleeve 7 is sealed with the inner wall of the outer sleeve 6, and the inner sleeve 7 can slide up and down in the outer sleeve 6, and the lower end of the inner sleeve 7 is a closed structure;

[0026] The bottom of the cylinder body 4 is connected with an air distribution chamber 11, the air distribution chamber 11 is provided with an air conduit 12, the lower end of the air conduit 12 is communicated with the inner wall of the air distribution chamber 11, and the upper end extends into the lower end of the inner sleeve 7, and It is sealingly matched with the inner sleeve 7;

[0027] The bottom of the cylinder body 4 is also connected with a mounting seat 1...

Embodiment 2

[0031] This embodiment will further illustrate the technology. The top surface of the mounting seat 18 is provided with a card slot that communicates with the longitudinal through hole. The outer wall of the bottle bottom of the sampling bottle 3 is provided with a plurality of conducting holes 2 , the sampling bottle 3 is further provided with a floating body 8 , and the outer wall of the floating body 8 is in sealing fit with the inner wall of the sampling bottle 3 . The sampling bottle 3 is set up by way of upside down, the floating body 8 inside is located close to the bottle mouth at the initial position, and the surface of the floating body 8 can be used as a sealing structure between the floating body 8 and the inner wall of the sampling bottle 3 by wrapping a flexible rubber layer, etc. Since the lateral through hole in the mounting seat 18 is in a closed state in the initial state, the bottle mouth of the sampling bottle 3 will also be in a closed state. When the sampl...

Embodiment 3

[0034]This embodiment will further illustrate the technology, the outer wall of the inner sleeve 7 is provided with a first annular groove, the first annular groove is provided with a first expansion belt 13, and the middle of the first expansion belt 13 is convex outward in the initial state The outlet is sealingly matched with the inner wall of the outer sleeve 6 , and the bottom of the first annular groove is provided with a plurality of air holes that communicate with the interior of the inner sleeve 7 . The first expansion belt 13 can be made of elastic material such as rubber, which covers the bottom of the first annular groove and shields the air holes. When the inner sleeve 7 shrinks into the outer sleeve 6, the internal air pressure increases, and some air The air hole will enter the first annular groove, and the first expansion belt 13 will be pushed outward, and the first expansion belt 13 will expand to form a closed air structure with the inner wall of the outer ca...

Abstract

The invention belongs to the technical field of water environment monitoring, and particularly relates to a multi-layer depth sampling device for water environment monitoring. The device comprises a barrel and a plurality of sampling bottles, the top of the barrel is connected with an outer sleeve extending downwards, an inner sleeve is arranged in the outer sleeve, the outer wall of the inner sleeve is in sealing fit with the inner wall of the outer sleeve, the inner sleeve can slide up and down in the outer sleeve, and the lower end of the inner sleeve is of a closed structure; the bottom of the barrel is connected with an air distribution chamber, an air guide pipe is arranged on the air distribution chamber, the lower end of the air guide pipe is communicated with the inner wall of the air distribution chamber, and the upper end of the air guide pipe extends into the lower end of the inner sleeve and is in sealing fit with the inner sleeve; the bottom of the cylinder body is also connected with mounting seats in one-to-one correspondence with the plurality of sampling bottles, transverse through holes and longitudinal through holes are formed in the mounting seats, and one ends of the transverse through holes are used for being connected with inlets of the sampling bottles. A plurality of samples can be taken out in a single sampling process, and the plurality of samples can be water quality samples at different depths.

Description

technical field [0001] The invention belongs to the technical field of water environment monitoring, and in particular relates to a multi-layer depth sampling device for water environment monitoring. Background technique [0002] Environmental monitoring refers to the determination of environmental quality (or pollution degree) and its changing trend through the determination of representative values ​​of factors affecting environmental quality. Water quality monitoring is the process of monitoring and measuring the types of pollutants in the water body, the concentrations and changing trends of various pollutants, and evaluating the water quality. [0003] At present, when the water environment monitoring multi-layer depth sampling device samples the water body, only one sample bottle of water can be taken at a time, and the sample bottle used for storing the sample water body needs to be replaced frequently when sampling the water body multiple times. cumbersome.
