Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a UAV-based device for intercepting floating debris in river channels. Background Technology

[0002] In existing river management, the interception of floating debris is a significant and ongoing problem. Traditional river debris interception devices mostly employ nets or fences at fixed locations. This design proves inadequate when dealing with variations in the amount of floating debris across different river sections, seasons, and water flow conditions. For example, when there is little floating debris, deploying nets at fixed locations may increase water flow resistance, and the overall operation relies on manpower and boats, resulting in low efficiency and poor mobility.

The take-up roller assembly is installed inside the interception seat, and the interception net is wound around the take-up roller assembly; The flipping assembly is installed inside the interceptor seat and located below the take-up roller assembly. The flipping assembly and the take-up roller assembly are connected by a pair of meshing gears. The interceptor mesh is connected to the flipping assembly at the end away from the take-up roller assembly.

[0004] Preferably, the take-up roller assembly includes: The take-up roller is rotatably installed inside the interception seat. The two shaft ends of the take-up roller extend out of the side ends of the interception seat, and the interception net is wound around the take-up roller.

[0011] Compared with the prior art, the present invention has the following advantages: This utility model provides a drone-based river debris interception device.

Detailed Implementation

[0015] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Example: Please refer to the following: Figures 1 to 5 This embodiment provides a drone-based river debris interception device, comprising: The interceptor seat 10 has an open bottom and is installed at the bottom of the UAV body 1. Take-up roller assembly 11 is installed inside interceptor seat 10, and interceptor net 12 is wound around take-up roller assembly 11; The flipping assembly 13 is installed inside the interceptor seat 10 and located below the take-up roller assembly 11. The flipping assembly 13 and the take-up roller assembly 11 are connected by a pair of meshing gears 14. The end of the interceptor net 12 away from the take-up roller assembly 11 is connected to the flipping assembly 13.

[0017] The working principle and beneficial effects of the above technical solution are as follows: This utility model discloses a drone-based river debris interception device. When the drone body 1 hovers above the river, the take-up roller assembly 11 operates, thereby unfolding the interception net 12 wrapped around it. Simultaneously, the take-up roller assembly 11 drives the flipping assembly 13 to rotate synchronously via the gear 14, realizing the complete unfolding of the interception net 12 and forming an interception surface to capture river debris. When retracting, the take-up roller assembly 11 operates in reverse, realizing the rewinding and flipping reset of the interception net 12. The drone-based river debris interception device provided by this utility model realizes the automatic deployment and flipping linkage of the interception net, improving the deployment flexibility and retrieval convenience of the device. Compared with traditional fixed fences, it significantly reduces manpower input and water flow resistance, is suitable for dynamic river environments, and improves overall interception efficiency.

[0018] In this embodiment, the take-up roller assembly 11 includes: The take-up roller 15 is rotatably mounted inside the interceptor seat 10. The two shaft ends of the take-up roller 15 extend out of the side ends of the interceptor seat 10. The interceptor net 12 is wound around the take-up roller 15. The drive motor 16 is mounted on the top of the interceptor seat 10, and the output end of the drive motor 16 is connected to the shaft end of the take-up roller 15 through the pulley assembly 17.

[0019] The working principle of the above technical solution is as follows: The output of the drive motor 16 transmits power to the shaft end of the take-up roller 15 through the pulley assembly 17, thereby enabling the take-up roller 15 to rotate in both directions and thus controlling the unfolding or winding process of the interception net 12.

[0020] In this embodiment, the flipping component 13 includes: The main shaft 18 is rotatably mounted inside the interceptor seat 10. Both ends of the main shaft 18 extend out of the side ends of the interceptor seat 10, and the main shaft 18 is located below the take-up roller 15. Side-tilting arms 19, a pair of side-tilting arms 19 are mounted on the main rotating shaft 18, and the side-tilting arms 19 are against the inner wall of the interceptor seat 10; The sliding rod 20 is located at the end of a pair of side-tilting arms 19 away from the main rotating shaft 18, and the end of the intercepting net 12 away from the take-up roller 15 is connected to the sliding rod 20.

[0021] The working principle and beneficial effects of the above technical solution are as follows: The main rotating shaft 18 is driven by a pair of gears 14 to rotate, causing the side-flipping arm 19 to flip along the inner wall of the interception seat 10. The end of the side-flipping arm 19 pulls the interception net 12 downward through the sliding rod 20 to form an arc-shaped or planar interception surface. When resetting, it rotates in the opposite direction to achieve upward folding. The design of the side-flipping arm 19 close to the inner wall reduces the shaking during the flipping process, improves the uniformity and stability of the unfolding of the interception net 12, is suitable for different river widths, and expands the application range.

[0022] In this embodiment, the side-tilting arm 19 has a groove 21 at the end away from the main rotating shaft 18, and a columnar slider 26 is slidably connected in the groove 21. The columnar slider 26 is mounted on the weight block 22, and the weight block 22 is mounted on the end of the sliding rod 20.

[0023] The working principle and beneficial effects of the above technical solution are as follows: The sliding connection between the chute 21 and the columnar slider 26 allows the sliding rod 20 to automatically adjust its position during the flipping process. The weight 22 provides additional downward force to ensure that the interception net 12 is fully tensioned and fits the water surface when it is deployed, thereby improving the interception coverage and anti-fall-off performance and enhancing the adaptability of the device in turbulent water flow.

[0024] In this embodiment, a counterweight 23 is installed on the side of the interceptor seat 10 away from the winding roller assembly 11.

[0025] The beneficial effects of the above technical solution are as follows: The counterweight 23 balances the overall center of gravity of the interceptor seat 10 by gravity, preventing the device from tilting or shifting when the drone hovers or when impacted by water flow, thus improving the stability of the interceptor seat 10, ensuring the accurate positioning of the interceptor net 12, and reducing operational risks.

[0026] In this embodiment, a locking block 24 is installed on the inner wall of the interceptor seat 10 to limit the rotation angle of the side-flipping arm 19.

[0027] The working principle and beneficial effects of the above technical solution are as follows: The locking block 24 restricts the excessive rotation of the side-tilting arm 19 when it is flipped to the vertical position, thereby improving the safety and positioning accuracy of the flipping assembly 13.

[0028] In this embodiment, a pair of gears 14 includes a large gear and a small gear. The large gear is mounted on the end of the main shaft 18, and the small gear is mounted on the shaft end of the take-up roller 15.

[0029] The working principle and beneficial effects of the above technical solution are as follows: The pinion drives the large gear to rotate as the take-up roller 15 rotates. The gear meshing achieves synchronous linkage with the main shaft 18. Adjusting the gear ratio controls the matching of the flipping speed and the take-up speed. The size difference between the large and small gears provides a speed reduction and torque increase effect, ensuring that the flipping assembly 13 obtains sufficient torque at low speeds, improving transmission efficiency and load resistance, making it suitable for intercepting large floating objects.

[0030] In this embodiment, the top of the interceptor seat 10 is mounted on the bottom of the UAV body 1 via a rotating platform 25.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
