Portable quantitative water pumping device

Abstract

The invention discloses a portable quantitative water pumping device which is characterized in that rollers are fixedly mounted at four corners of the bottom end of a base, a water storage tank is fixedly mounted at one end of the top of the base, and a water sample quantitative sampling mechanism is arranged at the top of the base. A hydraulic telescopic rod drives a piston plate to move in the water storage tank, the size of a water storage space in the water storage tank is changed, then different sampling capacity requirements are met, a sealing gasket is attached to the inner wall of the water storage tank all the time, the sealing effect is achieved, water cannot permeate to the other side, and the sampling efficiency is improved. Meanwhile, when the piston plate moves, the moving position of the piston plate can be observed through the transparent position observation plate, the moving distance of the piston plate can be known according to the scale marks on the position observation plate, then the size of the provided water storage space is known, and samples with the corresponding capacity are collected according to the provided space during sampling.

Description

technical field [0001] The invention relates to the technical field of water sample collection, in particular to a portable quantitative water pumping device. Background technique [0002] In the process of monitoring environmental and biological indicators of rivers, lakes, reservoirs, ponds, and some experimental water bodies, it is usually necessary to sample, detect and analyze the target water bodies. The sampling volume is often different. In general research, the conventional water sampling device can basically meet the corresponding sample volume requirements. However, for special needs, due to the difference in content, it may be necessary to first collect a large amount of water. The water sample is concentrated, and the concentrated sample is taken for detection and analysis. At this time, the conventional water collector is used to collect the sample, which often cannot meet the sampling requirements; [0003] However, most of the current water collectors are of...

Problems solved by technology

[0002] In the process of monitoring the environmental and biological indicators of rivers, lakes, reservoirs, ponds, and some experimental water bodies, it is usually necessary to sample and detect and analyze the target water body. In the actual operation process, according to the research purpose and the content of various substances in the water body The sampling volume is often different due to the difference. In general research, sampling with a conventional water collector can basically meet the corresponding sample volume requirements. However, for special needs, due to the different content, it may be necessary to collect a large amount of water The water sample is concentrated, and the concentrated sample is taken for detection and analysis. At this time, the conventional water collector is used to collect samples, which often cannot meet the sampling requirements;

[0003] However, most of the current water collectors are fixed-capacity, and it is impossible to take a large number of water samples. The total amount of water in ponds and rivers is too much. Usually, dozens of liters of water samples, or even hundreds of liters of water samples are used for testing. Too little water sample can easily lead to errors in test results, so the present invention provides a portable quantitative pumping device to meet people's needs
