Down-pressing water sample collecting device for water reservoir

Abstract

The invention discloses a down-pressing water sample collecting device for a water reservoir, the down-pressing water sample collecting device comprises a remote control ship. The remote control shipis fixedly provided with a horizontal support plate. The support plate is fixedly provided with a plurality of collection units, and each collection unit comprises an upper sleeve tube and a lower sleeve tube which are fixed on the upper and lower end surfaces of the support plate, a collecting tube inserted in the lower sleeve tube, and a lifting rod inserted in the upper sleeve tube; the upper end of the collecting tube is provided with a collecting slot, and the lower end of the lifting rod penetrates through the supporting plate and is fixed to the top end of the collecting tube, the upperend of the lifting rod is fixedly provided with a top block; a driving unit is arranged above the collecting unit, the driving unit comprises a driving cylinder, a pressing plate fixed on a piston rod of the driving cylinder, and a plurality of down pressing units in one-to-one correspondence to the collecting units, the down pressing units are arranged on the pressing plate, and each down pressing unit includes a pressing rod inserted on the pressing plate, a rack formed on the side wall of the pressing rod, a gear meshing with the rack, and a motor for driving the gear to rotate. The down-pressing water sample collecting device is convenient to be applied to water sample collection at various points in the water reservoir.

Description

Technical field: [0001] The invention relates to the technical field of detection auxiliary devices, in particular to a press-down water sample collection device for reservoirs. Background technique: [0002] Environmental monitoring is to track the changes in environmental quality and determine the level of environmental quality through the detection of the content and emission of various substances that have an impact on humans and the environment, providing the basis and guarantee for environmental management and pollution control. Simply put, knowing the level of the environment and conducting environmental monitoring are the prerequisites for carrying out all environmental work. Environmental monitoring usually includes processes such as background investigation, plan determination, site optimization, on-site sampling, sample delivery, experimental analysis, data collection, and analysis and synthesis. On-site sampling is an important part of environmental monitoring a...

Problems solved by technology

On-site sampling is an important part of environmental monitoring and testing. For example, in reservoir environmental monitoring, the data source comes from the collected water samples, and the collected water samples come from various points in the reservoir. The existing method is manual collection by personnel by boat , its labor intensity is relatively high, especially for some seasick staff, manual collection is difficult
