Description

Technical Field

[0001] This utility model relates to the field of surface water sampling technology, specifically to a surface water sampling device based on a drone. Background Technology

[0002] Drone-based surface water sampling equipment is a highly efficient, flexible, and intelligent environmental monitoring tool. By integrating drone technology with an automated sampling system, it enables rapid sampling in complex water bodies. The equipment typically carries lightweight sampling bottles, multi-parameter water quality sensors, and a robotic arm. It hovers precisely at the target location via remote control or a preset flight path, collecting water samples using pump suction or gravity-based mechanisms, and supports stratified sampling at different depths. Traditional drone-based surface water sampling devices require the drone to hover above the water surface. Drones are unstable in windy conditions, leading to reduced accuracy in stratified water sampling and posing a risk of the drone falling into the water. Utility Model Content

[0003] The purpose of this invention is to provide a surface water sampling device based on a drone, in order to solve the problems mentioned in the background art. Traditional drone surface water sampling devices require the drone to hover above the water surface when collecting surface water. When the drone is hovering, it is unstable in the face of high wind speeds, which reduces the accuracy of water stratification sampling and poses a risk of the drone falling into the water.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a surface water sampling device based on an unmanned aerial vehicle (UAV), comprising two portal frames. A crossbeam is provided between the lower ends of the two portal frames, and a connecting seat is provided between the lower ends of the two portal frames and the crossbeam. The portal frames are fixedly connected to the crossbeam through the connecting seat. Protective sleeves are provided at both ends of the crossbeam and on the outside of the portal frames. Floating blocks are provided on the two portal frames and above the connecting seat. A mounting plate is provided between the upper sides of the two portal frames, and the two ends of the two mounting plates are engaged with the portal frames. A mounting groove is provided in the middle of the two mounting plates.

[0005] Preferably, the floating block is a cuboid structure made of rigid polyurethane foam. A through hole is provided on the inner side of the floating block at the position corresponding to the portal frame. The floating block is sleeved with the portal frame through the through hole and reinforced by adhesive bonding. A beveled groove is provided at the outer corner of the floating block.

[0006] Preferably, both ends of the two mounting plates are provided with snap-fit ​​seats, and the upper end of the snap-fit ​​seat is provided with a snap-fit ​​groove at the position corresponding to the portal frame, and the portal frame is snapped into the snap-fit ​​seat through the snap-fit ​​groove.

[0007] Preferably, both ends of the crossbeam extend to the outside of the floating block, and the protective sleeve is disposed on the outer end of the crossbeam.

[0008] Preferably, a fixing bolt is provided on the snap-fit ​​seat and through both sides of the snap-fit ​​groove.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the design of the mounting structure based on the UAV surface water sampling device allows the UAV to float on the water surface via a floating block, avoiding the instability of the UAV hovering on the water surface when facing high wind speeds, resulting in higher accuracy of water stratification sampling and reducing the risk of the UAV falling into the water.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5This utility model provides a surface water sampling device based on a drone, including two portal frames 1. A crossbeam 2 is provided between the lower ends of the two portal frames 1. A connecting seat 3 is provided between the lower ends of the two portal frames 1 and the crossbeam 2. The portal frames 1 are fixedly connected to the crossbeam 2 through the connecting seat 3. Protective sleeves 4 are provided at both ends of the crossbeam 2 and on the outside of the portal frames 1. Floating blocks 5 are provided on the two portal frames 1 and above the connecting seat 3. A mounting plate 6 is provided between the upper sides of the two portal frames 1. The two ends of the two mounting plates 6 are snapped into the portal frames 1. A mounting groove 7 is opened in the middle of the two mounting plates 6.

[0018] In use, the portal frame 1 is mounted on the lower end of the drone via the mounting plate 6. The crossbeam 2 is fixedly connected to the lower end of the portal frame 1 via the connecting seat 3, and protective sleeves 4 are set at both ends of the crossbeam 2 to provide support for the drone's landing. The water quality sampling device is mounted on the lower end of the mounting plate 6 via bolts through the mounting slot 7, ensuring that the water quality sampling device is set inside the portal frame 1, and that the lowest end of the water quality sampling device is located between the lower end of the floating block 5 and the crossbeam 2. The floating block 5 is set on the outside of the portal frame 1. When the drone carries the water quality sampling device to sample the water, the floating block 5 provides buoyancy to the overall structure, making the overall structure float on the water surface. At this time, the lower end of the water quality sampling device is below the water surface to sample the water quality. When the drone completes sampling and lands, the crossbeam 2 rests on the ground, and the lower end of the water quality sampling device is positioned above the crossbeam 2 to prevent damage to the water quality sampling device from the impact during landing.

[0019] The floating block 5 is a cuboid structure made of rigid polyurethane foam. A through hole 8 is provided on the inner side of the floating block 5 at the position corresponding to the portal frame 1. The floating block 5 is sleeved with the portal frame 1 through the through hole 8 and reinforced by adhesive bonding. A beveled groove 9 is provided at the outer corner of the floating block 5. The floating block 5 is sleeved with the lower end of the portal frame 1 through the through hole 8 and reinforced by adhesive bonding. The beveled groove 9 is provided on the outer side of the floating block 5 to prevent damage to the sharp corners of the floating block 5.

[0020] The two mounting plates 6 are provided with snap-fit ​​seats 10 at both ends. The upper end of the snap-fit ​​seat 10 is provided with a snap-fit ​​groove 11 at the position corresponding to the portal frame 1. The portal frame 1 is snapped into the snap-fit ​​seat 10 through the snap-fit ​​groove 11. The mounting plate 6 is connected to the portal frame 1 through the snap-fit ​​seat 10 by the snap-fit ​​groove 11, thereby improving the connection strength between the two portal frames 1.

[0021] Both ends of the crossbeam 2 extend to the outside of the floating block 5, and the protective sleeve 4 is set at the outer end of the crossbeam 2, so that the crossbeam 2 and the protective sleeve 4 extend to the outside of the floating block 5, and the floating block 5 is protected by the crossbeam 2 and the protective sleeve 4.

[0022] Fixing bolts 12 are provided on the mounting base 10 and through both sides of the mounting groove 11. The fixing bolts 12 pass through the mounting base 10 to fix the portal frame 1 to the lower end of the drone.
