Description

Technical Field

[0001] The present invention relates to an unmanned aerial vehicle device with a surface water sampling function, belonging to the technical field of unmanned aerial vehicles. Background Technique

[0002] An unmanned aerial vehicle device with a surface water sampling function is a professional device integrating advanced aviation technology and intelligent control systems, aiming to efficiently and safely collect water samples from the water surface. The device is usually composed of core components such as an unmanned aerial vehicle body, a support structure, a suspension component, and a dedicated water intake device. The unmanned aerial vehicle body, as the framework and support platform of the device, is made of lightweight and high-strength materials to ensure good aerodynamic performance and flight stability. The support structure is used to fix and connect various components to ensure the stability of the entire device during flight. The suspension component is designed to keep the unmanned aerial vehicle at a certain height above the water surface during water sampling, reducing direct contact with the water surface, thereby extending the endurance and protecting the airframe, and being able to quickly and accurately cut into the water surface and collect water samples. The entire water intake process is highly automated and easy to operate, greatly improving the efficiency and safety of water sample collection, and is an important tool in modern environmental monitoring, water resource management and other fields.

[0003] As disclosed in the publication number (CN207540822U), a surface water quality sampler carried on a multi-rotor unmanned aerial vehicle includes a sampling bottle and a core shaft. The core shaft is arranged at the top of the sampling bottle, and the sampling bottle is externally connected to the multi-rotor unmanned aerial vehicle through the core shaft; the sampling bottle includes a connected conical upper part and a cylindrical lower part. A water intake is provided on the side wall of the cylindrical lower part. The side wall of the conical upper part above the water intake is a thick-wall side, and the side wall of the conical upper part above the opposite side of the water intake is a thin-wall side. The thickness of the thick-wall side is greater than that of the thin-wall side. This surface water quality sampler has a simple structure and is easy to use, and can effectively solve the funds and time spent on boat sampling, saving research costs; setting the side wall of the conical upper part above the water intake as a thick-wall side can make the center of gravity of the sampling bottle body consistent with the direction of the water intake, which is beneficial to flexibly controlling the sampling direction and angle, and facilitating the water flow as a sample to enter the sampling bottle from the water intake. However, when the sampling bottle of this technical solution takes water, it takes water by the way of water flow entering the water intake, and can only collect the uppermost water flow. The water entry depth is uncontrollable, and it is difficult to sample from different positions of the surface water.

[0004] As the publication number (CN105571905B), a surface seawater multi-point sampling device is disclosed, which is a surface seawater multi-point sampling device capable of performing multiple fixed-point water sample collections on the surface seawater in different waters. It includes a drone, a ranging device arranged on the drone for detecting the distance between the drone and the water surface, a cabin with an open lower end arranged on the drone, a support frame arranged in the cabin, a number of automatic water sampling devices arranged side by side on the support frame, and a lifting device for lifting the automatic water sampling device. Although this technical solution can achieve sampling at different positions in the surface water, when this solution is used, it is impossible to stop the machine to take water, and when landing, it is prone to problems such as tipping over and excessive impact force when contacting the ground, and the safety of use is not good, and there are certain drawbacks in the use process.

As the winding roller 1101 rotates, the winding and unwinding rope 1104 fixedly installed on the winding roller 1101 starts to be wound or released. One end of the winding and unwinding rope 1104 is connected to the U-shaped mounting seat 12. By winding and releasing the winding and unwinding rope 1104, the position of the U-shaped mounting seat 12 can be adjusted.

During use, start the micro motor 1501, and its output shaft will drive the bidirectional lead screw 1502 fixedly connected thereto to start rotating. Since the bidirectional lead screw 1502 is designed with reverse threads, when the lead screw rotates, the clamping sliders 1504 at both ends thereof will move in opposite directions respectively. The first clamping head 1505 and the second clamping head 1506 are respectively fixed on the two clamping sliders 1504. As the sliders move, the first clamping head 1505 and the second clamping head 1506 will gradually approach or move away from each other, so as to realize the clamping or release of the object to be clamped. The combination of the clamping and positioning grooves formed on the first clamping head 1505 and the second clamping head 1506 and the soft friction pads 1508 not only ensures the stability of clamping, but also can effectively protect the water intake head 17 from being damaged.
