River water quality detection device

Abstract

The invention discloses a riverway water quality detection device which comprises a bracket, a detection device and a sampling device; the bracket comprises a base and a supporting rod vertically arranged on the base; the sampling device comprises a sampling outer pipe and a sampling inner pipe; the sampling outer pipe comprises a sampling transverse pipe and a sampling vertical pipe; the detection device comprises a shell; the shell is internally provided with a detection unit and a sample placement groove; the detection unit comprises a testing electrode, a rotation mechanism used for driving the testing electrode to rotate and a lifting mechanism used for driving the testing electrode to move up and down; and a first lifting mechanism used for driving the detection device to move up anddown is also provided. For the riverway water quality detection device provided by the invention, by combining sampling and detection, detection can be performed directly in the sampling process, thedetection step is saved, and the detection accuracy is high; and in addition, the riverway water quality detection device performs sampling by enabling the sampling outer pipe to directly extend intoa riverway, avoids that the detection accuracy is influenced by movement due to water flow impact and is high in detection precision.

Description

technical field [0001] The invention belongs to the field of experimental instruments, and in particular relates to a river water quality detection device. Background technique [0002] River water quality detection includes sampling, inspection and other steps. When sampling, there are requirements for the water intake position and water intake depth of the river. At present, sampling is usually done by placing a sampling bottle with a rope into the water. It may be displaced by the impact of the water flow, which will affect the detection accuracy; moreover, the common sampling method is to take samples manually to the river, and then bring the samples to the laboratory for testing. The testing process is complicated, and due to various External factors can easily affect the accuracy of water quality testing. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a river channel water quality detection device, which...
