Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) sampling technology, specifically a sampling mechanism for an environmental monitoring UAV. Background Technology

[0002] Environmental monitoring refers to determining environmental quality (or pollution level) and its changing trends by measuring representative values ​​of factors affecting environmental quality. It involves tracking changes in environmental quality and determining the level of environmental quality through the detection of the content and emissions of various substances that affect humans and the environment, providing a foundation and guarantee for environmental management and pollution control. Simply put, understanding the environmental level and conducting environmental monitoring are prerequisites for all environmental work. Environmental monitoring typically includes processes such as background investigation, scheme determination, optimized site selection, on-site sampling, sample transportation, experimental analysis, data collection, and data synthesis. In general, it is a process of obtaining information through planning, sampling, analysis, and synthesis.

[0003] While the existing device makes it convenient for people to take samples from various parts of the water area, it solves the problem that existing water quality monitoring requires water quality sampling, the conditions in each part of the water area are different, and people can only take samples from the water near the shore, which is inconvenient for sampling far from the shore. However, this did not solve the problems of complex device structure, high cost, and difficulty in promotion. In addition, after sampling, the drone will carry a heavy water sample, and the increased pressure of the water sample during landing may damage the device structure. Therefore, a sampling mechanism for environmental monitoring drones is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a sampling mechanism for an environmental monitoring drone, in order to solve the problems mentioned in the background art, such as the complex structure, high cost, and difficulty in promotion of existing devices. At the same time, after sampling, the drone will carry a heavy water sample, and the increased pressure of the water sample during landing may damage the device structure.

[0005] To achieve the above objectives, this utility model provides a sampling mechanism for an environmental monitoring drone.

[0006] The device includes an unmanned aerial vehicle (UAV) body, a sampling mechanism fixedly installed at the bottom of the UAV body, a wire feeding device, a bolt fixedly installed at the bottom of the wire feeding device, a connecting bracket movably installed at the bottom of the bolt, a threaded groove inside the connecting bracket, a nut movably installed at the bottom of the bolt, a water-holding box fixedly installed at the bottom of the connecting bracket, and a buffer mechanism fixedly installed at the bottom of the UAV body. The buffer mechanism includes a splicing shell. Several splicing shells are fixedly installed at the bottom of the drone body. A buffer spring is fixedly installed inside the splicing shell. A damper is movably installed inside the buffer spring. A piston plate is fixedly installed at the bottom of the buffer spring and the damper. A support leg is fixedly installed at the bottom of the piston plate. By welding a splicing shell to each of the four corners at the bottom of the drone body, welding a buffer spring inside the splicing shell, installing a damper on the inner side of the buffer spring, and setting a piston plate at the bottom of the buffer spring and the damper, and welding a support leg to the bottom of the piston plate, the drone can reduce the pressure on the drone body and prevent damage to the device structure when sampling water sources, as the weight it catches is relatively large and the pressure it may experience when landing on the ground on the return trip is relatively large. A camera is fixedly installed on one side of the drone body. By installing a camera on one side of the drone body, it can be ensured that the drone's perspective can be obtained when the staff operates the drone. The drone body has several assembly brackets fixedly installed on both sides, and propellers are fixedly installed at the top of the assembly brackets. By setting four assembly brackets on both sides of the drone body and installing propellers at the top of the assembly brackets, the drone can be guaranteed to fly normally. The unmanned aerial vehicle is equipped with a landing gear at the bottom of its body, and an anti-slip pad is fixedly installed at the bottom of the landing gear. By setting the landing gear at the bottom of the unmanned aerial vehicle body, the landing gear is placed on the ground, and the anti-slip pad is installed at the bottom of the landing gear to prevent the device from sliding. The bottom of the water container is fixedly equipped with a sinker. By welding the sinker to the bottom of the water container, it is ensured that the water container can sink directly into the water when it falls.

[0007] Compared with the prior art, the beneficial effects of this utility model are: This sampling mechanism for an environmental monitoring drone involves installing a wire-laying device at the bottom of the drone body. A bolt is welded to the bottom of the wire-laying device, and a connecting bracket is movably mounted at the bottom of the bolt. The connecting bracket has a threaded groove inside, and the bolt and nut are matched. A water-collecting box is welded to the bottom of the connecting bracket. By starting the drone body, the wire-laying device and the bottom structure fly together. The drone is operated to a designated location on the lake surface, the wire-laying device is activated, and the water-collecting box is lowered. The water-collecting box can collect water from any location on the lake surface. After collection, the wire-laying device retracts the wire, thus facilitating collection and testing. The structure is simple and the cost is low.

[0008] The sampling mechanism of this environmental monitoring drone involves welding a splicing shell to each of the four corners of the drone's bottom. A buffer spring is welded inside the splicing shell, and a damper is installed inside the buffer spring. A piston plate is set at the bottom of the buffer spring and the damper, and a support leg is welded to the bottom of the piston plate. When sampling water sources, the weight that the drone catches is relatively large, and the pressure it may experience when landing on the ground on the return trip is also relatively large. Under the action and reaction forces of the buffer spring and the damper, the pressure on the drone body is reduced, preventing damage to the device structure. Attached Figure Description
