Combined multifunctional water quality sampler

Abstract

The invention relates to a combined multifunctional water quality sampler. The combined type multifunctional water quality sampler comprises a sample suction device, a capstan type lifter and an adjustable supporting seat, wherein the sample suction device comprises a pull rope cable, a limiting disc, a fixing plate, a base and a plurality of sampling assemblies; the capstan type lifter comprises a control panel, a cylindrical connecting piece, a relay switch, a magnetic control switch, a telescopic rod, a capstan and a waterproof cover; and the adjustable supporting seat comprises a supporting base and a supporting frame hinged to the supporting base. According to different sampling conditions, the sample suction device and the capstan type lifter are combined or the sample suction device, the capstan type lifter and the sample suction device are combined, multiple samples can be obtained through one-time sampling, and the sampling device is convenient to carry and operate, high in sampling efficiency and stable in performance.

Description

technical field [0001] The invention relates to a combined multifunctional water quality sampler, which belongs to surface water quality detection instruments such as rivers and lakes. Background technique [0002] The water quality of surface water bodies such as rivers and lakes is directly related to the national economy and human health, and its sampling and testing is one of the main contents of the national environmental protection supervision work. In the process of monitoring and sampling, unfavorable conditions such as long distances, sparsely populated, harsh environments, and changing climates are often encountered. These unfavorable conditions often bring great difficulties to sampling work, increase labor intensity, reduce work efficiency, and even Affect the reliability of sampling results. Therefore, a sampler that is easy to carry, has multiple functions, is quick to disassemble, has stable performance, and can adapt to various adverse environments can not o...

AI Technical Summary

Problems solved by technology

[0003] At present, the widely used sampler is equipped with various sensors, micro-pumps, and connected to the suction pipe. This structure has high efficiency, but there are certain disadvantages. For example, the patent application number CN201610572414.0 discloses a layered sampling system. Provide a layered sampler with simple structure and precise control, but its sampling system adopts the sampling method of sampling tube combined with sampling pump. Sampling is affected by the residual sample liquid in the sampling tube, the accuracy of the sample is affected, and it cannot really meet the requirements of the national water quality sampling specification

Another example is the patent application number CN201810578721.9, which discloses a multifunctional water quality sampler with fixed water level and depth, which can collect water samples at a predetermined water depth and has various functions, but the electronic components such as water depth sensors and small animal sensors must be Working underwater is not only expensive, but also easy to damage and has a high failure rate
