The device consists of a main part, an actuator and a mounting unit. The main part is made in the form of a housing, an actuator and a tool tray are fixed in its cavity. The actuator includes a servo mechanism and a locking mechanism. On the shaft of the servomechanism there is a roller with a cable fixed on it, passing through the bypass roller of the locking mechanism, forming a flexible inextensible connection with the rocking mechanism of the locking mechanism. The mount is made in the form of a bracket fixed by a lock of the locking and clamping mechanism. The clamp is fixed by means of a second cable passing through it on one side with a rocker of the locking mechanism, and the other end of the second cable is designed to secure the payload. EFFECT: high reliability of fixing payload during transportation. 5 ill.

Description

Application area

The utility model relates to the equipment of unmanned aerial vehicles for dropping payload in flight.

State of the art

A known system of mechanical load shedding for a quadrocopter [https://www.youtube.com/watch?v=ZsfJ1dzJ-1k, 03/05/2014], which contains a payload shedding mechanism and a servo drive.

A device for fixing or dumping volumetric bodies for ultralight aircraft [patent RU No. 2587318, 06/20/2016], selected for the prototype, which contains the main part, the actuator and the mount for the actuator. The main part is a p-shaped profile that is bolted to the aircraft body. The actuator consists of a rotating shaft with a lever mounted on it and an electric motor.

The disadvantage of these devices is the unreliability of securing the payload during transportation.

Utility Model Essence

The technical task of the proposed solution is to create a device that provides the ejection or retention of the payload during transportation.

The technical result is the high reliability of securing the payload during transportation.

The technical result is achieved by the fact that in the device for fastening and dumping the payload containing the main part, the actuator and the mount, according to the proposed solution, the main part is made in the form of a container, in the cavity of which the actuator and lodgement are rigidly fixed, the actuator includes a servomechanism and the locking mechanism, a roller with a cable fixed to it passing through the bypass roller of the locking mechanism is located on the shaft of the servomechanism, forming a flexible inextensible I have a connection with the rocker of the locking mechanism, the attachment unit is made in the form of a bracket fixed by the bolt of the locking mechanism and the clamp, fixed with a second cable passing through it, on the one hand with the rocking mechanism of the locking mechanism, and the other end of the second cable is designed to secure the payload.

Utility Model Implementation

The device consists of a main part 1, made in the form of a container, in the cavity of which the actuator and lodgement 2 are rigidly fixed. The actuator consists of servo-mechanism 3 and the locking mechanism 4 connected in series. The locking mechanism 4 consists of a roller 5, a first cable 6, a bypass roller 7, the shutter 8, the spring 9 and the rocker 10. The rocking chair 10 includes an axis 11, a cracker 12, a pin 13. The attachment point of the payload 14 consists of a second cable 15, a clamp 16 and a bracket 17. The payload 14 has a protection battening pin 18 with the ring.

A roller 5 is fixed at the output end of the servomechanism shaft 3, on which a first cable 6 is sealed, connecting the bypass roller 7 and the rocker pin 13. Clamp 16 is connected via the second cable 15 to the rocker pin 13 on one side and the loop girth on the other with the ring of the safety check 18 of the payload 14. The axis 11 of the rocker 10 is fixed between the shutter 8 and the spring 9. The payload 14 is laid on the lodgement 2 and secured by a bracket 17, which is fixed by the shutter 8.

The device operates as follows

The command signal enters the servo mechanism 3, in which the drive starts to rotate the output shaft, on the end of which the roller 5 is fixed. The roller 5 wraps the first cable 6, which drives the rocker 10 through the bypass roller 7. The rocker 10 has two motion paths, which are determined by the movement fixed on it with a cracker 12, along the grooves molded on the mating surfaces of the main part 1. The first path corresponds to the rotational movement of the rocker 10 relative to the axis 11 rigidly fixed between the shutter 8 and the spring 9. This is This allows pulling out the ring with the safety pin 18 from the payload 14, thereby leading to the use of the product. The second trajectory corresponds to the linear movement of the rocker 10 along the spring 9, which brings the shutter 8 to its extreme position, triggering the dumping mechanism of the payload 14. After the first trajectory of the rocking 10, motion can stop, which ensures the self-liquidation effect of the UAV.

Thus, the proposed solution provides high reliability of fixing, throwing out or holding the payload during transportation. Also, the device allows using UAVs to quickly deliver payloads to hard-to-reach places.
