Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles (UAVs), in particular to a bird-repelling mechanism for a UAV. Background Art

[0002] Bird strikes are defined by the International Civil Aviation Organization as a major Class A air disaster hazard. Airports employ various bird-repelling methods, including scarecrows, inflatable figures, automatic laser bird repellents, falcons, vehicles, and bird-detecting radars. However, these methods are susceptible to time and airspace constraints and suffer from poor effectiveness. A new method for bird repelling has emerged, using drones with bird-repelling components.

[0003] However, existing drone bird repellent systems typically use sonication or chemicals. While sonication is effective, it's also expensive and can't guarantee it won't harm other plants and animals. Chemicals are cheaper, but they're less effective in moving air, taking a long time to diffuse, hindering the effectiveness of the repellent. Summary of the Invention

[0004] The purpose of the utility model is to provide a bird-repelling mechanism for a drone, which utilizes the airflow generated when the drone is flying to make a bird-repelling box emit a loud sound to drive away birds. The cost is low and the bird-repelling effect is also good.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: to provide a bird-repelling mechanism for a drone, including a drone component, the drone component including a drone body, a bird-repelling component arranged below the drone body, the bird-repelling component including a bird-repelling box, a wind collecting plate fixedly connected to the side wall of the bird-repelling box, a rolling groove provided inside the bird-repelling box, a ball bearing provided inside the rolling groove, an air inlet groove provided on the side wall of the bird-repelling box, an air outlet groove provided on the upper surface of the bird-repelling box, a flow groove provided on the inner wall of the air outlet groove, a diversion groove provided on the lower surface of the flow groove, and the diversion groove and the air inlet groove are both connected to the rolling groove.

[0007] Optionally, a connecting ring is fixedly connected to the upper surface of the bird-repelling box, a spring groove is provided on the inner surface of the connecting ring, a spring is fixedly connected to the inner wall of the spring groove, and a clamping block is fixedly connected to one end of the spring.

[0008] Optionally, the side walls of the drone body are fixedly connected with arms, and the number of the arms is four.

[0009] Optionally, a motor is fixedly connected to the upper surface of the arm, a rotating shaft is fixedly connected to the output end of the motor, a blade is fixedly connected to the outer surface of the rotating shaft, the blade is located above the wind collecting plate, and a protective shell is fixedly connected to the outer surface of the arm.

[0010] Optionally, a battery slot is provided on the upper surface of the drone body, a battery is fixedly connected to the inner bottom of the battery slot, and a cover is fixedly connected to the inner wall of the battery slot.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The utility model is provided with a motor, a rotating shaft, blades, an air collecting plate, an air inlet groove, a rolling groove, a diverter groove, a flow groove, and a ball bearing. When the drone is started, the output end of the motor drives the rotating shaft and blades to rotate, causing the blades to generate a downward airflow. The airflow is directed to the air inlet groove through the air collecting plate. The airflow enters the rolling groove through the air inlet groove and is divided into two streams by the diverter groove. One stream enters the flow groove upward, and the other stream enters the rolling groove to drive the ball bearing to rotate. The ball bearing continuously cuts the airflow during the rotation process, thereby generating a loud noise to drive away birds. The utility model uses the airflow generated by the drone during flight to make the bird repellent box emit a loud noise to drive away birds. It is low-cost and has a good bird repellent effect.

[0013] The utility model is provided with a bird-repelling box, a connecting ring, an installation groove, a clamping block, a fixed cone ring, a spring, a movable cone ring and a limiting ring. When the bird-repelling box needs to be installed, the connecting ring is aligned with the installation groove, and the bird-repelling box is pressed upward to make the connecting ring move upward, so that the inclined surface of the clamping block is squeezed against the inclined surface of the fixed cone ring, and the clamping block moves in a direction close to the spring, and the spring contracts and continues to move until the clamping block contacts the lower surface of the movable cone ring, driving the movable cone ring to move upward together. At this time, the spring gradually rebounds, and the clamping block gradually moves in a direction away from the spring. The clamping block squeezes the movable cone ring to make it move upward until the spring completely rebounds. At this time, the clamping block is located between the fixed cone ring and the movable cone ring, and the driving ring is pulled downward. The bird box cannot be removed, thus completing the installation of the bird repellent box; when it is necessary to remove the bird repellent box, continue to press the bird repellent box upwards so that the inclined surface of the card block continues to squeeze the movable cone ring, and the limit ring blocks the movable cone ring so that it cannot move. At this time, the card block moves in the direction close to the spring, and the spring contracts until the card block moves to contact the conical surface of the movable cone ring. Slowly pull the bird repellent box downward so that the card block drives the movable cone ring to move downward until the lower surface of the movable cone ring fits into the upper surface of the fixed cone ring. Continue to pull the bird repellent box downward. At this time, the card block continues to squeeze the conical surface of the movable cone ring, so that the bird repellent box can be removed, making the utility model more convenient to transport and carry.
