Remote-control sampling device for water quality detection

Abstract

The invention discloses a remote-control sampling device for water quality detection. The device comprises a remote control ship, wherein a sampling mechanism is mounted on the remote control ship andcomprises a mounting plate and a plurality of sampling tubes fixed on the bottom surface of the mounting plate, the sampling tubes are annularly and uniformly distributed around the center of the mounting plate, a water inlet is formed in the wall of the upper end of each sampling tube, each sampling tube outside the water inlet is sleeved with a rotary sealing sleeve, and a water inlet slot matched with the water inlet of each sampling tube is formed in each rotary sealing sleeve; support lugs are formed on the outer walls of the rotary sealing sleeves, rotating rods are fixed on the supportlugs, the upper ends of the rotating rods penetrate through circular arc slots formed in the mounting plate, a first compressed spring is connected between each rotating rod and the side wall of oneend of the corresponding circular arc slot, a second compressed spring is connected between each rotating rod and the side wall of the other end of the corresponding circular arc slot, a push cylinderwith a piston rod matched with one rotating rod is arranged on one side of one rotating rod and fixed at one end of a rocker arm. The device is conveniently applied to water sampling at each site ofa reservoir.

Description

Technical field: [0001] The invention relates to the technical field of detection auxiliary devices, in particular to a remote-controlled water quality detection and sampling device. 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 monitor...

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
