Hydrological water quality one-time automatic sub-package sampling bag

Abstract

A disposable automatic subpackage sampling bag for hydrology and water quality, which can meet the requirements of water quality monitoring for water sample storage, effectively block the pollution of water samples caused by water sample storage containers, and is easy to carry, saves space, and can reduce the labor intensity of sampling personnel ,Improve work efficiency. Including the body of the water sample collection bag, the top of which is provided with a liquid inlet check valve and an exhaust valve. There are multiple water sample collection bag bodies with different volumes. The pipe is connected to the water separator. The water inlet of the water separator is connected with a three-way pipe, a peristaltic pump hose, a medical transition hose and a sampling head in sequence. One end of the three-way pipe connected to the water separator is provided with a pressure valve inside. Connecting room, the other end of the three-way pipe is connected to the peristaltic pump rubber hose, the side port of the three-way pipe is connected to the buoyancy exhaust valve, the top of the sampling head is equipped with a counterweight steel ball, and the other end is connected to the medical transition hose. There are four radial water inlets distributed in a cross shape on the outer periphery.

Description

technical field [0001] The invention relates to a hydrology and water quality sampling device, in particular to a hydrology and water quality one-time automatic subpackage sampling bag, which is suitable for use in conjunction with a hydrology and water quality automatic subpackage sampler. Background technique [0002] In recent years, the process of industrialization is advancing rapidly. Facing the new situation, the status quo of urban water pollution has also become more serious. In the current state, water resources in many areas are being polluted, which objectively proves the importance of water quality sampling and water quality control. From the perspective of the whole process of water quality monitoring, on-site sampling should belong to the key link, and at the same time, it also constitutes the first step. After on-site sampling, if accurate and comprehensive water quality samples can be obtained, it will help the smooth development of water quality monitorin...

Problems solved by technology

[0005] 2. Since many sampling bottles of different volumes are required for each sampling, the space occupied by the bottles is relatively large, and it is inconvenient to carry, which brings certain troubles to the sampling work

[0006] 3. It takes a lot of time to wash the sampling bottles at the sampling site, and the collection of sewage also requires the sampling personnel to use the water at the sampling site to wash the sampling bottles several times, which brings certain health problems to the sampling personnel. the threat of

[0007] In summary, the current water sample storage containers are not only inconvenient to carry, but also time-consuming and labor-intensive in the process of use, resulting in low work efficiency, poor work safety, high labor intensity for sampling personnel, and insufficient washing before use. Monitoring accuracy has a certain impact
