Furthermore, left side elevating gear and right side elevating gear independent motion respectively can drive left side elevating gear and right side elevating gear independent lift, when the synchronous lift of left side elevating gear and right side elevating gear of both sides, is used for adjusting the high position of adjusting plate 13 in first frame 36, when left side elevating gear stops motionless right side elevating gear up-and-down motion, is used for adjusting plate 13's inclination and incline direction.

In this embodiment, as shown in fig. 3, the number of the parking plates 29 is not less than 1, adjacent parking plates 29 are parallel to each other, the surface of each layer of parking plate 29 is provided with a fixed gripper 31 and a rotary gripper 30, the fixed gripper 31 and the rotary gripper 30 are located on the same axis, the axis of the fixed gripper 31 and the rotary gripper 30 is the same as the telescopic direction of the telescopic transmission device, the fixed gripper 31 is located on the side away from the first frame 36, the rotary gripper 30 is located on the side close to the first frame 36, the fixed gripper 31 is used for limiting one side of the unmanned aerial vehicle and determining the stroke end point of the unmanned aerial vehicle, and the rotary gripper 30 is in transmission connection with the overturning motor and used for limiting the other side of the unmanned aerial vehicle.

A plurality of layers of shutdown plates 29 are arranged in the second frame 37 from top to bottom, the edge of each layer of shutdown plate 29 is also provided with a limit sensor 32, each limit sensor 32 is used for providing an alignment signal for aligning the adjusting plate 13 and the limit sensor 32, and a plurality of shutdown plates 29 in the second frame 37 can provide a field for shutdown of a plurality of unmanned aerial vehicles.

When the unmanned aerial vehicle is recycled, the working mode of the multi-unmanned aerial vehicle three-dimensional hangar is as follows:

step 1, the unmanned aerial vehicle attitude adjusting device is in a static state and receives an unmanned aerial vehicle recovery instruction, and the left lifting device and the right lifting device synchronously lift and drive the adjusting plate 13 to move to a preset height;

step 2, acquiring the inclination angle between the adjusting plate 13 and the horizontal plane by an inclination angle sensor fixedly installed on the adjusting plate 13, driving the right support assembly 28 to move upwards or downwards through the right lifting device, and adjusting the adjusting plate 13 to be in a state parallel to the horizontal plane;

step 3, the unmanned aerial vehicle takes the centering mark as a target point and lands on the upper surface of the adjusting plate 13;

step 4, the unmanned aerial vehicle falls into the upper surface of the adjusting plate 13 and then is positioned between the left clamping arm and the right clamping arm, the central gear 1 is driven by the centering motor to rotate, and the first rack 3 and the second rack 4 are driven to respectively drive the left clamping arm and the right clamping arm to move oppositely;

step 5, after the left clamping arm and the right clamping arm are both contacted with the unmanned aerial vehicle frame, centering of the unmanned aerial vehicle in the X-axis direction is completed, and a centering motor is stopped;

step 6, the front gripper 22 and the rear gripper 17 of the left clamping arm move relatively under the drive of the second conveyor belt 21, the front gripper 22 and the rear gripper 17 of the left clamping arm move relatively under the drive of the first conveyor belt 20, the two groups of front grippers 22 and the rear gripper 17 move synchronously under the drive of the motor, and when pressure sensors arranged on the contact surfaces of the two groups of front grippers 22 and the rear gripper 17 acquire pressure signals, the centering of the unmanned aerial vehicle in the Y-axis direction is completed;

step 7, stopping the gripper driving motors for driving the first conveyor belt 20 and the second conveyor belt 21 to complete the centering of the unmanned aerial vehicle on the upper surface of the adjusting plate 13 and lock the unmanned aerial vehicle;

step 8, after the unmanned aerial vehicle is locked, the unmanned aerial vehicle posture adjusting device realizes that the adjusting plate 13 is parallel to the shutdown plate 29 under the control of the left lifting device and the right lifting device;

step 9, the left lifting device and the right lifting device synchronously drive the adjusting plate 13 to lift, drive the adjusting plate 13 to align with the idle stop plate 29, and limit the adjusting plate 13 through the limit sensor 32 on the idle stop plate 29;

step 10, the fixed unmanned aerial vehicle is pushed to the shutdown plate 29 through the telescopic transmission device, at the moment, when one side of the outer frame of the unmanned aerial vehicle is clamped into the fixing hand grip 31, the rotating hand grip 30 is driven by the motor to be turned upwards, and the other side of the outer frame of the unmanned aerial vehicle can be fixed.

And 11, loosening and resetting the left clamping arm, the right clamping arm, the two groups of front grippers 22 and the two groups of rear grippers 17.

The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention.
