Creeping-type water quality sampling device for water quality detection and water quality sampling method

Abstract

The invention discloses a creeping-type water quality sampling device for water quality detection and a water quality sampling method. The creeping-type water quality sampling device comprises a shellbody, an adjustable water quality sampling device and a gas driving device, wherein the adjustable water quality sampling device and the gas driving device are both installed on the shell body, the adjustable water quality sampling device is used for sampling water, and the gas driving device is used for driving the whole creeping-type water quality sampling device to creep; the adjustable waterquality sampling device comprises a turntable group, a submersible pump, a first T-shaped three-way valve, a first interface guide pipe, a first metal snakelike hose, a first hard guide pipe, a secondhard guide pipe, a second metal snakelike hose, a second interface guide pipe and a sample water storage disc; and the gas driving device comprises gas distribution plates arranged in side bins, telescopic gas supply devices communicated with the side bins located at the top part of the shell body, and gas guide pipes communicating the adjacent side bins. The creeping-type water quality samplingdevice has the advantages of wide water quality sampling range, high flexibility, adjustable sampling water quantity and accurate sampling.

Description

technical field [0001] The invention belongs to the technical field of sampling tools for water quality detection, and in particular relates to a submerged water quality sampling device and a water quality sampling method for water quality detection. Background technique [0002] The existing water quality sampling equipment has the following defects: [0003] 1. The scope of water quality sampling is limited; [0004] 2. The sample water volume of water quality sampling is not well controlled and the flexibility is poor; [0005] 3. Water quality sampling is easy to mix with water from other locations, resulting in inaccurate sampling and further reducing the accuracy of water quality testing. [0006] Based on the above reasons, the present invention designs a submersible water quality sampling device for water quality detection, which has the advantages of wide range of water quality sampling, high flexibility, adjustable sampling water volume and accurate sampling.
