Technical Field

The invention relates to the technical field of unmanned aerial vehicles, in particular to a winding and unwinding device for mooring an unmanned aerial vehicle.

Background

The unmanned aerial vehicle is used as equipment of a load video acquisition and transmission system, and has wide application in occasions such as movie shooting, news interview, field evidence collection, air patrol and the like. The existing unmanned aerial vehicle generally has the following two modes, one mode is an unmanned aerial vehicle with a power battery, and the power battery is used for providing power to drive a motor to rotate a propeller to generate power for flying; the other type is heavy unmanned aerial vehicle, is mooring unmanned aerial vehicle promptly, and its power supply is on ground, connects unmanned aerial vehicle through the power supply cable and provides power for unmanned aerial vehicle. The unmanned aerial vehicle corresponding to the former mode is limited by factors such as load, volume, flight time and the like, and cannot meet the requirement of long-time operation; mooring unmanned aerial vehicle system is by many rotor unmanned aerial vehicle, mooring cable, ground take off and land the platform and constitute, mooring unmanned aerial vehicle uses the long-time stagnation of ground power supply to hang and stop, simultaneously, data such as the high definition video that airborne equipment gathered can pass back to ground through the built-in optic fibre of mooring cable, have aerial long-time operation, the big advantage of data transmission bandwidth, but entire system stand alone type installation also can on-vehicle installation to can automatic synchronization follow the vehicle and remove.

At present, the mode of receiving and releasing of mooring unmanned aerial vehicle mainly has two kinds: one type is a ground lifting type, when a flight task is executed, a tethered unmanned aerial vehicle and ground equipment need to be dismounted from a transport vehicle, when the tethered unmanned aerial vehicle is recovered, the tethered unmanned aerial vehicle and the ground equipment need to be re-loaded, various equipment cannot be placed and reliably fixed according to a uniform fixed position, the operation is extremely complicated, the operation is limited by environmental factors, and the equipment cannot move; the other type of the retractable platform of the mooring unmanned aerial vehicle modified by the pick-up truck is adopted, the ground equipment is installed in the rear carriage of the modified pick-up truck, and the mooring unmanned aerial vehicle is installed on a lifting mechanism in the rear carriage of the pick-up truck; when the tethered unmanned aerial vehicle executes a flight task, the top of the rear carriage of the pick-up truck needs to be opened, the tethered unmanned aerial vehicle is jacked to the top of the rear carriage of the pick-up truck by using a lifting mechanism, a retraction platform is combined, and then the tethered unmanned aerial vehicle can be operated to take off; the retractable platform is positioned at the top of the rear carriage of the modified pick-up truck, the height of the retractable platform exceeds more than 1.7 meters, when the tethered unmanned aerial vehicle is released or recovered, personnel need to climb to the retractable platform on the roof to mount or dismount the blades of the unmanned aerial vehicle so as to take off or recover the tethered unmanned aerial vehicle, and the operation is dangerous and extremely inconvenient; the lifting mechanism has a complex structure and low use reliability.

Disclosure of Invention

The invention provides a retraction device for a mooring unmanned aerial vehicle, aiming at solving the technical problems that the existing mooring unmanned mechanism is complex, complicated to operate and incapable of moving.

The technical scheme adopted by the invention is as follows: the retraction device for the tethered unmanned aerial vehicle comprises a trailer, wherein a generator, a power supply box and a rotating shaft box are arranged on the trailer, and a sealed cabin for storing the tethered unmanned aerial vehicle is arranged on the trailer; the cabin comprises a bottom plate, a cabin body above the bottom plate and a baffle capable of opening and closing the cabin body, the cabin body is connected with the bottom plate in a sliding mode, and the baffle is hinged to the bottom plate. The generator provides electric power for unmanned aerial vehicle, and the power supply box converts the electric power of generator into different voltage electric current and provides with electrical apparatus, and the pivot case is used for receiving and releasing of unmanned aerial vehicle cable. When the mooring unmanned aerial vehicle is in a non-working state, the mooring unmanned aerial vehicle is positioned on the bottom plate in the cabin body, and the cabin body provides a safe, stable, dust-free and rain-proof protection environment for the mooring unmanned aerial vehicle; when mooring unmanned aerial vehicle is in operating condition, open the baffle, the drive cabin body slides for the bottom plate, until mooring unmanned aerial vehicle exposes completely, can carry out mooring unmanned aerial vehicle's taking off. The invention provides a bearing platform with proper height and no potential safety hazard for the tethered unmanned aerial vehicle, and maintenance personnel can maintain the tethered unmanned aerial vehicle by standing on the ground; the structure is simple, blades do not need to be disassembled and assembled when the tethered unmanned aerial vehicle takes off or recovers, and the preparation time is short; the mooring unmanned aerial vehicle can be towed to a place where work is needed along with the trailer, and can fly along with the trailer synchronously in the flying process, so that the universality is greatly improved.

Further, the base plate is provided with a guide rail, the base plate is provided with a roller mechanism matched with the guide rail, the cabin body is arranged on the guide rail, and the cabin body can synchronously slide relative to the base plate along with the guide rail. The cabin body is arranged on the guide rail, the cabin body can move relative to the base plate along with the guide rail, and then the unmanned aerial vehicle is conveniently moored to open or close, and the roller mechanism reduces the friction force between the guide rail and the base plate, so that the guide rail can slide more smoothly relative to the base plate, and the structure is simple and the operation is convenient.

Further, the device also comprises a power mechanism for driving the guide rail to slide relative to the bottom plate; the power mechanism comprises a motor, a first synchronous belt wheel, a first synchronous belt, a second synchronous belt wheel, a rotating shaft, a third synchronous belt wheel, a second synchronous belt and a synchronous belt idler wheel which are sequentially connected.

Further, the roller mechanism comprises a transverse roller and a longitudinal roller. The transverse roller and the longitudinal roller enable the bottom plate and the guide rail to be attached more tightly in the transverse direction and the longitudinal direction, so that the bottom plate and the guide rail are connected more stably, and the derailment phenomenon can be avoided.

Further, the cabin body comprises a first cabin body, a second cabin body and a third cabin body which are connected in sequence, the second cabin body is arranged on the inner side of the first cabin body, the first cabin body is fixedly connected with the guide rail, and the second cabin body and the third cabin body are connected with the guide rail in a sliding manner. The guide rail is provided with a sliding chute matched with the second cabin body and the third cabin body, and the second cabin body and the third cabin body can slide on the guide rail, so that the length of the cabin body is further shortened. Compare in integral cabin body, move to the position that exposes the unmanned aerial vehicle completely at the cabin body from the position that shields the unmanned aerial vehicle of mooring, make the stroke distance of cabin body shorter through the slidable cabin body, reduced corresponding power take off and part quantity, area occupied is littleer, the structure is simpler, improved winding and unwinding devices's overall stability simultaneously.
