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

Abstract

The invention discloses a hydrological water quality one-time automatic sub-package sampling bag, which can meet requirements of water quality monitoring on water sample storage, and effectively blockthe pollution caused by a water sample storage container to a water sample, is convenient to carry, saves space, and can reduce the labor intensity of sampling personnel and improve the working efficiency. The hydrological water quality one-time automatic sub-package sampling bag comprises water sample collecting bag bodies, wherein the top end of each water sample collecting bag body is providedwith a liquid inlet check valve and an exhaust valve; the water sample collecting bag bodies have different volumes; the water inlet of the liquid inlet check valve is connected with a water separator through a single water supply pipe respectively; the water inlet of the water separator is sequentially connected with a tee pipe, a peristaltic pump hose, a medical transition hose and a sampling head; the end of the tee pipe, connected with the water separator, is provided with a connecting chamber with a pressure valve, and the other end of the tee pipe is connected with the peristaltic pumphose; a side port of the tee pipe is connected with a buoyancy type exhaust valve; the top end of the sampling head is provided with a counterweight steel ball, and the other end of the sampling headis connected with the medical transition hose; and the periphery of the sampling head is provided with four radial water inlets distributed in a crossed shape.

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
