Description

Technical Field

[0001] The utility model relates to the technical field of water sampling by unmanned aerial vehicles, in particular to an automatic quantitative water sampling device for water quality sampling mounted on an unmanned aerial vehicle. Background Art

[0002] Water quality sampling is one of the key links in water quality monitoring. At present, conventional water quality sampling methods have transitioned from manual sampling to automatic sampling at water quality automatic stations, and from automatic sampling to remote sampling methods such as drones. Conventional water quality sampling methods can meet most water quality sampling scenarios, but if there are sudden environmental events (such as tailings dam breaches and chemical plant explosions), conventional sampling methods are powerless. Remote sampling methods such as drones are a good supplement to traditional sampling methods. It greatly broadens the spatial scope of water quality sampling, breaks through the water surface area that can be reached by normal humans, and quickly and accurately collects the required water samples.

[0003] The Chinese authorized patent document with publication number CN207423589U relates to a device carried by a drone and using a submersible pump to collect water samples. The fixed bracket is fixed directly below the drone, and the sampling controller, automatic hose reel, and sampling bottle are installed on the fixed bracket. The sampling tube is rolled on the rotating wheel of the automatic hose reel, and the end is connected to a micro submersible pump; the water outlet of the automatic hose reel is connected to the water inlet of the sampling bottle. The sampling bottle is equipped with a liquid level detector and an overflow pipe; the drone is equipped with a sampling controller controlled by a remote terminal. The utility model uses a drone as a carrier and power source. The drone is equipped with a micro submersible pump. After reaching the specified height of the specified water area, the remote terminal controls the automatic hose reel to automatically lower the sampling tube to below the water surface, and the water sample is pumped into the sampling bottle to complete the sampling. The sampling bottle is carried by the drone for return. The utility model can adapt to water quality sampling in various complex areas, especially in areas where sampling personnel cannot reach, and can be intelligently and efficiently sampled, and the sampling meets the water quality sampling specifications.

[0004] The above-mentioned existing technologies cannot realize the quantitative and rapid sampling of water quality, and the overall installation and operation of the equipment is relatively complicated and cumbersome. Therefore, it is necessary to develop an automatic quantitative water sampling device for water quality mounted on a drone. Utility Model Content
