Detailed Description
The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.
It will be understood that terms such as "having," "including," and "comprising," when used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
As shown in fig. 1-5, the low-damage capturing device for the unmanned aerial vehicle comprises a launching device 1, a recovery device 2, a capturing net bomb 3 and a traction recovery rope 4, wherein one end of the traction recovery rope is fixed at the tail part of the capturing net bomb, the rest part of the traction recovery rope is wound on the recovery device, and the launching device is used for launching the capturing net bomb; the recovery device is a fishing vessel type take-up and pay-off device and is arranged on or near the transmitting device; the recovery device releases the traction recovery rope without resistance when catching the net bomb to launch, and the motor drives the roller to rapidly wind and recover when recovering the traction recovery rope.
The catching net bullet comprises a cylindrical shell 310, and the shell comprises from the head to the tail: the device comprises a proximity device 5, a catching net 6, a parachute bag 7, a compressed air tank 8 and a controller 9; the proximity device is arranged in the middle of the capturing net, the capturing net is connected with the parachute bag, and the capturing net is connected with the inner wall of the shell case or the compressed air tank through a rope; the proximity device is used for surveying the distance with unmanned aerial vehicle, proximity device and controller electric connection, and the controller is according to the signal that proximity device fed back, and when unmanned aerial vehicle was in the seizure scope of catching the net, control compressed gas jar release compressed gas will catch net and parachute package blowout. The proximity device is low in cost and simple in structure, can detect target information according to changes of physical fields such as a sound field and a magnetic field, and is suitable for capturing the unmanned aerial vehicle flying at low altitude and low speed; the shell can be made of light materials such as engineering plastics. When the catching net is small and is easy to scatter, the proximity device can select a distance sensing device without power (explosive force), and when the catching net is large and is not easy to scatter, the proximity device can select a passive proximity fuse with low explosive force (on the premise of not damaging the winding rope).
The catching net comprises a plurality of winding ropes 610, one ends of all the winding ropes are fixed together, the other ends of all the winding ropes are respectively and fixedly provided with a propeller locking device 620, the propeller locking device is a spring 621, the top and the bottom of the spring are respectively provided with a cross brace 622, the two cross braces are connected through a connecting wire 623, and the connecting wire is an elastic rope or a flexible column. If the weight of the spring is too light, a small lead weight can be additionally arranged at the bottom of the spring to increase the inertia during dispersion.
Catch the net after the transmission, each winding rope is scattered rapidly and is opened, and the screw blade is after touchhing the screw lock device, and the screw blade enters into the gap of the adjacent two screw threads of spring easily, and then touches the connecting wire, and the connecting wire atress is crooked, drives the spring compression and tightens up, and then holds the screw blade tightly, and the winding rope that reachs later further lives rotatory screw winding, and the screw receives the winding and is locked, no longer rotates, and unmanned aerial vehicle is caught. If only with the rope, very having after the high-speed rotatory propeller blade of unmanned aerial vehicle is touch to the rope tip and can be bounced off, be difficult to play the winding constraint effect fast, through the screw lock device, make the propeller blade contact after the screw lock device not bounced off easily, the winding rope of follow-up arrival can further be accomplished the winding. The number of the spiral of the spring is enough, and the distance between every two adjacent spiral (in an unstressed state) is preferably smaller than or slightly larger than the thickness of the propeller blade.
The net is caught to be dynamic and rotatory in the air, and the height of different winding ropes is different, if catch the net release and fail to catch unmanned aerial vehicle in the twinkling of an eye, catch the net and also probably touch winding rope or screw locking device in follow-up removal or whereabouts process, catch the mode of catching for the net is once only spilt to ordinary net, catch the success rate higher.
Unmanned aerial vehicle is caught the back, by ground staff control recovery unit beginning work, and the rope is pull in quick rolling under motor drive, and the unmanned aerial vehicle of catching this moment is in between parachute and the recovery unit, and the lifting power of parachute prevents that unmanned aerial vehicle from falling fast and be close to recovery unit gradually, draws unmanned aerial vehicle near recovery unit, takes off the unmanned aerial vehicle of catching by the staff again and does further processing. The recovery device is provided with a damper, so that the recovery device and the power device can be temporarily disconnected and stalled when the rotating speed is too high and the traction force passes, and the traction recovery rope or the catching net is prevented from being broken due to overlarge traction force. If the proximity device cannot be triggered after the catching net bomb is launched, the catching net bomb can fall down to be dangerous, and therefore the function of manually triggering the proximity device in a remote control mode can be added to prevent accidents.
And a frosting layer is arranged outside the spring. The frosting layer can increase the friction between the spring and the propeller blade, and further reduce the probability that the propeller blade escapes from the spring.
The launching device adopts electromagnetism or compressed air as power to launch and capture net bullets, which are two launching modes with low cost and small pollution in the prior art.
The rotating speed of the capture net bullet after being launched is not less than 2r/s, so that the capture net can be rapidly opened under the action of centrifugal force after being released. The arrangement mode of the plurality of propeller locking devices in the cartridge case is preferably in a horn shape, so that the propeller locking devices are more favorable for quick dispersion after the spray of the propellers, and the capture area is maximized.
The bottom of the shell case is provided with a pull ring, and the traction recovery rope is connected with the pull ring through a hook so as to be convenient for quickly replacing the capture net bullet after the capture net is recovered.
In order to increase the catching success rate, one or more catching net bombs can be launched to increase the covering area of the catching net.
The number of the winding ropes is not less than 40, the length of a single winding rope is not less than 2m, and the lengths of the winding ropes are the same or different. The winding rope quantity is too few, and the clearance of two winding rope front ends is too big, probably causes unmanned aerial vehicle to leak the net from the clearance, consequently should guarantee sufficient winding rope quantity, and winding rope length is big more, and winding rope quantity is also more.
While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields suitable for the invention, and further modifications may be readily made by those skilled in the art, and the invention is therefore not limited to the specific details and embodiments shown and described herein, without departing from the general concept defined by the claims and their equivalents.
