An environmentally friendly water quality detection sampler with accurate sampling

Abstract

The invention relates to the technical field of environment-friendly water quality sampling and discloses an environment-friendly water quality detection sampler capable of accurately sampling. The sampler includes a housing, and a sliding groove is formed in the housing. The surface of the sliding groove is slidably connected with a gear. A ratchet wheel is movably connected to the surface of thegear; a screw rod is movably connected into the gear, a meshing wheel is movably connected to the surface of the screw rod, fan blades are movably connected to the surface of the meshing wheel, a drainage groove is movably connected to the end, away from the gear, of the screw rod, a water facing plate is fixedly connected to the surface of the drainage groove, a limiting groove is formed in thedrainage groove, and a torsion spring is movably connected into the limiting groove. Suction wind power is generated through rotation of the fan blades, water can be guided into a water storage bag through the suction wind power, meanwhile, the screw rotates to be meshed with the gear to rotate, the housing moves, the fan blades rotate to guide water of different depths into the water storage bag,and therefore the effect of sucking water samples of different depths through water flow force is achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection water quality sampling, in particular to an environmental protection water quality detection sampler with accurate sampling. Background technique [0002] Environmental quality monitoring is a kind of environmental monitoring content. It mainly monitors the distribution and concentration of pollutants in the environment to determine the state of environmental quality. The historical data of environmental quality monitoring at regular and fixed points is also provided for scientific research on the laws of pollutant migration and transformation. Basic data; among them, the quality inspection of water resources has become the top priority. [0003] The existing technology for testing water resources is sampling testing, and sampling testing equipment mostly detects water samples on the water surface, and the distribution area of ​​water resources is relatively large, and the range i...

AI Technical Summary

Problems solved by technology

[0003] The existing technology for testing water resources is sampling testing, and sampling testing equipment mostly detects water samples on the water surface, and the distribution area of ​​water resources is relatively large, and the range is wide. Only testing water samples on the surface cannot represent a The quality of the whole piece of water resources, so the detection errors are relatively large. In addition, the existing water resources detection equipment needs to rely on electronic components to complete the timing detection work, which has relatively large limitations. Therefore, an environmentally friendly water quality detection method with accurate sampling The sampler came into being
