[0002] With the widespread application of drones in surveying, inspection, logistics and other fields, drone recovery technology has become a key link to ensure their efficient operation. Existing drone capture and recovery devices have the following shortcomings: Poor interception adaptability: Traditional interception nets are mostly set at fixed angles, which are difficult to adapt to the complex flight trajectories and multi-angle impacts of drones, resulting in a low interception success rate.

DETAILED DESCRIPTION

[0021] See also Figures 1 to 5As shown, an embodiment of the present application provides an automatic interception, capture and recovery device for drones, comprising: a connecting disk 7, an interception mechanism, a capture mechanism 5 and a buffer mechanism 6. A hinged bracket is provided at the rear end of the connecting disk 7. The interception mechanism comprises an annular frame 11 provided in front of the connecting disk 7. An interception net 4 is provided at the edge of the annular frame 11. The interception net 4 is connected to the connecting disk 7 by an elastic rope to form a hemispherical interception area. The capture mechanism 5 is provided at the front side of the connecting disk 7, and the capture mechanism 5 at least partially extends into the hemispherical interception area for clamping the intercepted drone. The buffer mechanism 6 is provided at the front side of the connecting disk 7, and the front end of the buffer mechanism 6 is fitted with the back of the hemispherical interception area for buffering drones entering the hemispherical interception area.

[0022] In the above scheme, the center of the back of the interception net 4 is pulled by the set elastic rope, and the interception net 4 is installed by the set annular frame 11, so that the interception net 4 forms a hemispherical interception area, and the connecting disk 7 is hinged on the bracket, so that the interception mechanism can rotate a certain angle with the connecting disk 7, which is convenient for adjusting the angle of the interception net 4 according to the impact angle and flight trajectory of the drone, so that the drone falls into the center of the hemispherical interception area, thereby improving the interception success rate; the drone intercepted by the interception net 4 can be captured by the set capture mechanism 5. During the capture process, the buffer mechanism 6 is used to reduce the impact force of the drone on the capture mechanism 5, thereby avoiding damage to the capture mechanism 5 and the drone.

[0023] In some possible implementations, see Figures 1 to 5 As shown, a plurality of support rods 14 are evenly arranged in the circumferential direction of the annular frame 11 near the connecting plate 7. The end of the support rod 14 facing away from the annular frame 11 is fixed on the connecting plate 7. The support rod 14 is tilted inward from front to back, thereby improving the impact resistance and support stability of the annular frame 11.

[0024] In some possible implementations, see Figure 4 and Figure 5 As shown, the capture mechanism 5 includes a plurality of jaws 54 arranged along the circumferential direction, a gear 53 is provided at the lower end of the jaw 54, the gear 53 is mounted on the connecting plate 7 through a hinged mounting plate 56, and a meshing rack 52 is provided on one side of the gear 53. The plurality of racks 52 are connected by a cross connecting rod 51, and the cross connecting rod 51 is driven by a first hydraulic rod 55.

[0025] In the above scheme, when capturing the drone, the first hydraulic rod 55 is controlled to start, so that the output end of the first hydraulic rod 55 contracts. The contraction of the output end of the first hydraulic rod 55 drives the multiple racks 52 to move downward synchronously through the cross connecting rod 51. The multiple racks 52 move downward and drive the multiple gears 53 to rotate clockwise. The clockwise rotation of the multiple gears 53 drives the multiple clamps 54 to rotate clockwise around the hinge point of the gear 53, thereby clamping the drone.

[0026] In some possible implementations, see Figure 4 and Figure 5 As shown, a flexible cushion 57 is provided on the inner side of the clamping jaw 54 so that the drone will not be damaged when it is clamped.

[0027] In some possible implementations, see Figures 3 to 5 As shown, the buffer mechanism 6 includes an annular frame 61 that fits the back of the hemispherical interception area, and a plurality of flexible buffer pads 62 are evenly arranged along the circumferential direction of the annular frame 61 close to the hemispherical interception area. A plurality of elastic telescopic rods 63 are evenly arranged along the circumferential direction of the annular frame 61 on the side away from the flexible buffer pad 62, and the end of the elastic telescopic rod 63 away from the annular frame 61 is fixedly set on the connecting plate 7.

[0028] In the above scheme, when the drone collides with the interception net 4, the impact force is simultaneously transmitted to the multiple flexible buffer pads 62, causing the multiple elastic telescopic rods 63 to contract. Under the action of the multiple elastic telescopic rods 63, the impact force is absorbed, and at the same time, the multiple clamps 54 complete the clamping of the drone, reducing the impact of the drone on the capture mechanism 5 as a whole and on the drone.

[0029] In some possible implementations, see Figure 1 and Figure 2 As shown, the automatic interception, capture and recovery device for drones provided in the embodiment of the present application also includes a recovery plate 2, and the bracket is vertically arranged on the recovery plate 2. The bracket includes a vertical rod 8 arranged on the recovery plate 2, and a horizontal rod 13 is arranged on the upper end of the vertical rod 8 near the connecting plate 7. The end of the horizontal rod 13 facing away from the vertical rod 8 is hinged to the back of the connecting plate 7, and a second hydraulic rod 12 is hinged on the vertical rod 8 below the horizontal rod 13, and the output end of the second hydraulic rod 12 is hinged to the back of the connecting plate 7.

[0030] In the above scheme, when intercepting a drone, the second hydraulic rod 12 is first controlled to start, so that the output end of the second hydraulic rod 12 drives the connecting plate 7 to rotate around the hinge point between the upper end and the horizontal rod 13, so that the opening direction of the interception net 4 is toward the direction of the drone, so that the drone can fall into the center position of the hemispherical interception area, which is convenient for adjusting the opening direction of the interception net 4 according to the flight trajectory and flight angle of the drone, thereby improving the success rate of intercepting the drone.

[0031] In some possible implementations, see Figure 1 and Figure 2 As shown, a recovery frame 9 is further provided on the recovery plate 2 . The recovery frame 9 is located below the hemispherical interception area, and a recovery net bag 10 is provided at the edge of the recovery frame 9 .

[0032] In the above scheme, after the multiple clamps 54 complete the clamping of the drone, the second hydraulic rod 12 controls the connecting plate 7 to rotate around the hinge point between the upper end and the horizontal rod 13, so that the opening direction of the interception net 4 is toward the recovery net bag 10, and then the first hydraulic rod 55 is controlled to start, so that the output end of the first hydraulic rod 55 is extended, so that the output end of the first hydraulic rod 55 is extended and drives the multiple racks 52 to move upward synchronously through the cross connecting rod 51. The multiple racks 52 move upward and drive the multiple gears 53 to rotate counterclockwise. The multiple gears 53 rotate counterclockwise and drive the multiple clamps 54 to rotate counterclockwise around the hinge point of the gear 53, thereby releasing the drone and causing the drone to fall into the recovery net bag 10.

[0033] In some possible implementations, see Figure 1 and Figure 2 As shown, a base 1 is provided below the recovery plate 2 , and electric push rods 3 are provided around the base 1 and the recovery plate 2 .

[0034] In the above solution, in order to ensure that the drone is stably placed during the recovery process and avoid collision and damage, the electric push rod 3 can adjust the height as needed to adapt to different recovery scenarios and recovery equipment.

After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as they are within the scope of protection of the invention, they are protected by patent law.
