Shallow water sampling device and using method thereof

Abstract

The invention discloses a shallow water sampling device and a using method thereof, and relates to the technical field of environmental water quality monitoring. The device comprises a supporting rodand a sampling container, wherein the sampling container is provided with a sampling pipe in a matching manner, a spherical bag body is arranged in the sampling container, a water inlet is formed on aside wall of the sampling pipe, a limiting plate is further arranged in the sampling pipe in a matched mode, a piston is further arranged in the sampling pipe located below the limiting plate, a piston rod is fixed to a top side surface of the piston, a front end of the supporting rod is connected with a guide pipe through a plurality of connecting columns, the guide pipe is sleeved with the sampling pipe, a pulley is fixed at an end part of the guide pipe through a bracket, a first traction rope is fixed at an end part of the sampling pipe, the first traction rope is matched with the pulley,a pull ring is fixed at an end part of the first traction rope, and a second traction rope is fixed to a top end of the piston rod. The device is advantaged in that the device can be used for conveniently and quickly sampling for multiple times, accurate positioning and quantitative sampling are realized, moreover, sampling operation is simple, the labor is saved, and labor intensity is low.

Description

technical field [0001] The invention belongs to the technical field of environmental water quality monitoring, and in particular relates to a shallow water sample sampling device and a use method thereof. Background technique [0002] Water sample collection is an important link in the work of water quality monitoring and hydrological measurement for environmental protection. It is not a simple collection of water samples, because the water samples provided for analysis must be representative in order to accurately reflect the concentration and indicators of water quality parameters; and there are many factors that affect water sample collection, such as sampling points, sampling instruments, sampling volume, Changes in any of these factors, such as sampling methods and even storage of water samples, may lead to changes in analysis results. [0003] Chinese patent application number (CN200810148125.3), the application date is 2008-12-31, discloses a kind of shallow water ty...

Problems solved by technology

[0004] The above-mentioned sampler can only take samples according to the telescopic length of the grip rod, and at the same time, it needs to control the grip rod to control the movement of the sampling bottle for sampling during operation. Frequent use of sampling in a short period of time has the disadvantage of high labor intensity.
