Water sampling device used for water reservoir

Abstract

The invention discloses a water sampling device used for a water reservoir. The water sampling device comprises a remote control boat, wherein a sampling mechanism is arranged on the remote control boat and comprises a mounting plate and a plurality of sampling pipes fixedly arranged on the bottom surface of the mounting plate; a water inlet is molded on the pipe wall of the upper end of each sampling pipe; each sampling pipe located outside a water inlet is sleeved by a rotary sealing sleeve in an insertion manner; a water inlet groove opening matching with the water inlet of a sampling pipeis molded on each rotary sealing sleeve; a support lug is molded on the outer wall of each rotary sealing sleeve; a rotating rod is fixedly arranged on each support lug; the upper end of each rotatingrod penetrates through a circular arc groove molded on the mounting plate; a first compression spring is connected with and arranged between a rotating rod and the side wall of one end of a circulararc groove; a second compression spring is connected with and arranged between a rotating rod and the side wall of the other end of a circular arc groove; one side of each rotating rod is provided with a pushing cylinder with a piston rod matching with a rotating rod; each push plate is provided with a proximity switch matching with a rotating rod; and pushing cylinders are fixedly arranged on therotating plate. The water sampling device provided by the invention adopts a manner of remote control, and is convenient to be applied to water sample collection at various sites of the water reservoir.

Description

Technical field: [0001] The invention relates to the technical field of detection auxiliary devices, in particular to a water sample collection device used in 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 and test...

AI Technical Summary

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
