Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that existing water collectors have large volume, low extraction efficiency, easy disturbance of water bodies, inability to ensure in-situ water sample collection, and inability to apply to marsh wetlands with superficial shallow water. In order to solve the problems in deep-water wetlands where dense large emergent plants or submerged plants grow, and then provide an in-situ continuous sampler for wetland water samples

Abstract

In-situ continuous sampling device for water sample in wetland. The invention relates to a tool for acquiring a water sample, which aims to solve the problems that the conventional water sampler has large volume, easily disturbs a water body, cannot be suitable for a wetland water body growing intensive plants or a marsh wetland with surface shallow water, and the like. In the tool, a convex part at the lower end of a water pipe is inserted into an inner ring of a piston; the upper end of a piston carrier is inserted into the inner ring of the piston and is connected with the lower end of the water pipe; an opening is formed in the piston carrier; a piston assembly and a power adjustment spring are arranged in a hollow barrel water storage device; the outer ring of the piston of the piston assembly is attached to an inner wall at the upper end of the hollow barrel water storage device; the lower end of the hollow barrel water storage device is connected with a water inlet pipe; the upper end of the water pipe is connected with a water outlet pressing handle; a first sealing ring is arranged on an inner wall at the upper end of the water pipe; a water outlet sealing ball is arranged on the first sealing ring; a second sealing ring is arranged on an inner wall at the lower end of the hollow barrel water storage device; and a water inlet sealing ball is arranged on the second sealing ring. The tool is used for acquiring the water sample in the wetland.

Description

technical field [0001] The invention relates to a tool for collecting water samples, in particular to an in-situ continuous sampler for wetland water samples. Background technique [0002] Wetland water sample in-situ continuous sampler is a kind of in-situ stratified continuous collector for different wetland water bodies. The equipment needed for water chemical analysis sampling. [0003] In the past, when collecting water samples in wetlands, especially rivers and lakes, general-purpose water sampling devices (such as the SYCSQ-1 layered water quality sampler) were mainly used. Composed of lead weights and rope. When the water sample is collected, the rope is in a loose state, the movable cover is opened, sinks into the water, the water flows through the plexiglass bucket, and when it is placed in the water layer where the water sample needs to be collected, the rope is pulled upwards, the lower movable plate is closed, and the water is extracted. A plexiglass bucket c...
