Description

Technical Field

[0001] The utility model belongs to the field of environmental monitoring unmanned aerial vehicle sampling and relates to an unmanned aerial vehicle sampler. Background Art

[0002] Environmental monitoring is a process of intermittently or continuously observing, measuring, and analyzing the changes and environmental impact of one or more environmental elements or indicators for a specific purpose, in a pre-designed time and space, using comparable environmental information and data collection methods. Among them, water quality testing is a relatively important item in environmental testing. Water quality testing refers to the measurement and evaluation of the content, nature, quantity, type, and change trend of various pollutants in the water body to determine the water quality status and environmental health level of the water body. For outdoor water quality testing, with the rapid development of drones, the use of drones for outdoor water quality testing can monitor large areas of water such as rivers and lakes. At the same time, drones can also cross some areas with complex terrain and difficult to reach, and realize water quality monitoring in remote areas, expanding the coverage of water quality monitoring. In addition, when using drones for sampling, monitoring personnel do not need to take a boat to the sampling site. They only need to operate drones on the shore to complete water sample collection, which reduces the risk during the sampling process and improves the safety of monitoring personnel. However, most existing drone samplers can only take water samples at one point. After taking the samples, the sampler is suspended back to the shore by the drone, and after replacing the new sampling bottle, the water quality of other locations is sampled again. This kind of sampler is relatively time-consuming when used.

[0003] Therefore, the utility model provides a drone sampler to solve the above problems. Utility Model Content

[0018] The lower end of the U-shaped bracket 4 is fixedly connected to the two side edges of the circular floating plate 5, and 6 groups of magnetic rings 51 are installed in a circular array on the circumferential edge of the circular floating plate 5. A pin 41 is fixedly installed at the center of the lower surface of the middle beam of the U-shaped bracket 4, and a counterweight 42 is installed on the left side of the upper surface of the middle beam of the U-shaped bracket 4. The first gear 6 is rotatably mounted on the pin 41, and the right edge of the first gear 6 is meshed with the teeth of the second gear 7. The second gear 7 is fixedly mounted on the output shaft of the second motor 8. The second motor 8 body is installed on the right side of the upper surface of the middle beam of the U-shaped bracket 4. A micro water pump 9 is fixedly installed on the lower surface of the first gear 6, and the lower side pipe mouth of the micro water pump 9 is fixedly connected to the water pump 91. The lower end of the water pump 91 passes through the center of the circular floating plate 5, and the drainage pipe mouth of the micro water pump 9 is fixedly connected to the L-shaped drainage pipe 92.
