A combined multifunctional water quality sampler

Abstract

The invention relates to a combined multifunctional water quality sampler. A combined multifunctional water quality sampler includes a sample extractor, a disc lifter and an adjustable support base. The sample extractor includes a pull rope cable, a limit plate, a fixed plate, a base and multiple sets of sampling components; a capstan lift The device includes a control panel, a cylindrical connector, a relay switch, a magnetic control switch, a telescopic rod, a winch and a waterproof cover; the adjustable support base includes a support base and a support frame hinged with the support base; according to different sampling conditions, the sample is sucked It is easy to carry, easy to operate, high sampling efficiency, and stable in performance.

Description

technical field [0001] The invention relates to a combined multifunctional water quality sampler, which belongs to a surface water quality detection device 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. Sampling and testing are one of the main contents of the national environmental protection supervision work. In the process of monitoring and sampling, unfavorable conditions such as long distance, sparsely populated, harsh environment, and changeable climate are often encountered. These unfavorable conditions often bring great difficulties to the sampling work, increase labor intensity, reduce work efficiency, and even Affects 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 only ma...

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
