Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a warning device for a UAV hovering bracket. Background Art

[0002] In contemporary society, drone technology is increasingly being used in police work, including aerial surveillance, traffic management, search and rescue, and on-site investigations. Police departments utilize drone hovering platforms to conduct long-term surveillance of specific areas, improving law enforcement efficiency and safety. However, when drones are performing missions, particularly in crowded or complex environments, their hovering state can pose a potential safety risk to personnel on the ground.

[0003] Existing drones usually use alarms to alert ground personnel. However, this method makes it difficult for ground personnel to detect drones flying in the air and avoid them in the first place, which can easily cause injuries to ground personnel. In addition, when the drone falls, the ground will generate a reaction force to damage the drone, so it is necessary to add a shock-absorbing device to the bottom bracket of the drone.

[0005] The utility model proposes a warning device for a hovering bracket of an unmanned aerial vehicle, comprising a unmanned aerial vehicle, wherein a control system is fixedly installed inside the unmanned aerial vehicle, and a connecting bracket is detachably fixed to the middle part of the bottom of the unmanned aerial vehicle, connecting pipes are fixedly installed on both sides of the two bottoms of the connecting bracket, and a support seat is fixedly installed on the end of each connecting pipe, an alarm is installed on one side of the connecting bracket at the bottom of the unmanned aerial vehicle, and a sensor is installed on the other side of the connecting bracket at the bottom of the unmanned aerial vehicle.

[0006] Preferably, a reflective groove is provided at the bottom of each connecting tube, and a bidirectional screw is rotatably fixed in the middle of each connecting tube, and a first annular movable plate is threadedly fixed to one end of the bidirectional screw, and a second annular movable plate is threadedly fixed to the other end of the bidirectional screw, a first annular baffle adapted to the inner wall of the connecting tube is fixed to the bottom of the first annular movable plate, a second annular baffle adapted to the inner wall of the connecting tube is fixed to the bottom of the second annular movable plate, and a reflective plate is fixed to the upper part of the first annular baffle at the lower part of the bidirectional screw inside the connecting tube.

[0007] Through the above technical solution, the setting of the first annular baffle and the second annular baffle can block the reflector when it is not in use, thereby facilitating operation and not affecting operation due to reflection from the reflector. When encountering people during descent, the reflector opens, making it easier for people to observe the drone and preventing the drone from causing damage to people when it falls.

[0008] Preferably, a first mounting groove is provided at the bottom of the support seat, and a telescopic column is fixedly provided on the top wall of the first mounting groove, and a spring is sleeved on the outer wall of the telescopic column inside the first mounting groove, and a support plate adapted to the first mounting groove is fixedly installed at the bottom of the telescopic column, and shock-absorbing rubber is installed at the bottom of the support plate.

[0009] Through the above technical solution, the spring and the shock-absorbing rubber cooperate with each other to create a buffer when the drone lands, thereby preventing the reaction force of the ground from causing damage to the drone.

[0010] Preferably, a second mounting slot is provided inside the support seat above the first mounting slot, a micro motor is fixed on the top of the second mounting slot, and the drive shaft of the micro motor rotates through the support seat and is coaxially fixed with the bidirectional screw through a coupling; a battery box is installed at the bottom of the micro motor inside the second mounting slot, and a battery slot is provided on the side of the battery box away from the connecting tube.

[0011] Through the above technical solution, the motor and the battery box cooperate with each other, so that the battery can drive the motor to move, thereby enabling the motor to drive the first annular baffle and the second annular baffle to overlap or separate with each other.

[0012] Preferably, the support seat is provided with a first movable groove on the side away from the connecting pipe, and a second movable groove is provided on the outside of the first movable groove, a threaded groove is provided in the middle of the outside of the second movable groove, a baffle is fixed inside the second movable groove, and a box support plate adapted to the first movable groove is fixed to the bottom of the baffle, and an annular groove is provided in the middle of the baffle, and a fastening bolt adapted to the threaded groove is rotatably fixed in the middle of the annular groove.

[0013] Through the above technical solution, the function of tightening the bolts can conveniently fix the baffle inside the second movable groove, thereby achieving sealing of the support seat.

[0014] Preferably, a sealing rubber is fixedly provided on the bottom of the baffle around the box abutment plate.

[0015] Through the above technical solution, the role of the sealing rubber makes the sealing effect better and can play a waterproof role.

[0016] The beneficial effects of the present invention are:

[0017] 1. By setting up a control system, an alarm, a sensor, a reflector, a bidirectional screw, a first annular baffle, a second annular baffle, a micro motor and a battery box, the sensor can detect the state of the ground when the drone is falling. When a person is detected on the ground, the sensor transmits the information to the control system, so that the control system controls the micro motor to operate, thereby separating the first annular baffle and the second annular baffle, exposing the reflector, and the control system controls the alarm to sound an alarm in the first time, so that ground personnel can discover the drone in the first time and respond in the first time to prevent the drone from harming ground personnel.

[0018] 2. By setting up the coordination between the spring, telescopic column, support plate and shock-absorbing rubber, when the drone falls to the ground, the shock-absorbing rubber and spring act as a buffer to prevent the reaction force of the ground from causing damage to the drone.

[0019] 3. By setting the interaction between the fastening bolts, baffles, threaded grooves, and sealing rubber, the fastening bolts can drive the baffles to form a detachable seal on the support seat, and the sealing rubber can make the sealing effect better, thereby achieving a waterproof effect.

[0034] Working principle: when in use, when the drone is falling, the sensor 7 detects the situation on the ground. When someone is found on the ground, the sensor 7 transmits the detected information to the control system 2, so that the control system 2 controls the alarm 6 to alarm, and at the same time the control system 2 controls the micro motor 507 to operate, so that the first annular baffle 405 and the second annular baffle 406 are separated from each other, thereby exposing the reflector 8, making it easier for ground personnel to observe the drone and thus facilitate avoidance. When falling to the ground, due to the action of the spring 503 and the shock-absorbing rubber 506, the reaction force of the ground on the drone can be absorbed, thereby reducing the damage to the drone by the ground.
