Description

[0002] Water quality testing is the process of testing and analyzing the physical, chemical and biological properties of water, aiming to evaluate the quality, safety and suitability of water. Through regular or irregular testing, we can obtain real-time data of various indicators in water and understand the current status of water quality and its changing trends.

[0003] Water quality sampling equipment is a commonly used equipment in the process of water quality testing. Most of the existing technologies use drones to carry collection devices for movement, and change the position of the collection device by drone, so that the collection device is located in a predetermined collection area, and then the collection area collects water samples from the designated water area, and then the collected water samples are subsequently tested to monitor the water quality of the target water area. However, this method still has some problems. The position between the existing collection device on the drone and the drone is fixed. In order to avoid interference with the drone by fish in the water during sampling or to avoid the drone being too close to the water surface, the collection device needs a certain length. If the length is too long, during parking or flying to the collection area, it will cause collision between the ground or trees and the collection device, which will cause damage to the collection device and cause failure of water sample collection.

[0004] Therefore, how to complete the water sample collection is a problem that needs to be solved at present. Utility Model Content
