Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles, and in particular relates to a coaxial double-rotor unmanned aerial vehicle based on laser counter-radiation. Background Art

[0002] After a traffic accident occurs, it often takes some time for ground police to arrive at the scene, during which time it is easy to attract onlookers and traffic jams, which will bring a series of negative effects, such as causing secondary accidents, hindering medical rescue, destroying the accident scene, etc., and causing trouble for police investigation. Therefore, rapid isolation and warning of the accident scene is very important.

[0003] Existing traffic warning and isolation equipment include traffic cones, warning isolation lines, alarm lights, warning signs, night lighting equipment, etc. The limitation is that they all need to be arranged manually. Since it takes a certain amount of time for ground police to arrive at the scene, there is a certain lag. More importantly, the life safety of police officers is easily threatened during the arrangement of warning and isolation equipment. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1:

[0028] See also Figure 1-Figure 7 As shown, a coaxial dual-rotor UAV based on laser beaming includes:

[0029] Coaxial twin-rotor mechanism 1;

[0030] A rotating shaft 2, which is arranged at the bottom end of the coaxial twin-rotor mechanism 1;

[0031] The fuselage 3 is sleeved on the outside of the rotating shaft 2;

[0032] A foldable landing gear 4 is mounted on the outer side wall of the fuselage 3 .

[0033] An upper rotor 5 is installed at the top of the coaxial twin-rotor mechanism 1, a lower rotor 6 is installed at the bottom of the coaxial twin-rotor mechanism 1, an internal power mechanism 7 is arranged inside the coaxial twin-rotor mechanism 1, a laser shooting mechanism 8 is arranged outside the fuselage 3, a transmitting end 9 is installed inside the fuselage 3, a receiving end 10 is installed on the outer wall of the fuselage 3, a camera 11 is fixedly installed on the outer wall of the fuselage 3, an alarm light 12 is installed inside the foldable landing gear 4, and a ground projection mechanism is installed on the outer wall of the bottom end of the fuselage 3 13, an infrared sensor detector 14 is arranged on one side of the ground projection mechanism 13, the fuselage 3 is in the shape of a regular triangular prism, three foldable landing gears 4 are arranged, the three foldable landing gears 4 are all connected to the bottom end of the fuselage 3 through a rotating shaft, and an alarm light 12 is installed inside the three foldable landing gears 4, the laser shooting mechanism 8 and the camera 11 are both installed on the outer side wall of the fuselage 3, and the camera 11 is installed on one side of the fuselage 3, and the angle formed by the two laser shooting mechanisms 8 and the rotating shaft 2 is 120°.

[0034] Specifically, the upper rotor 5 and the lower rotor 6 can be folded for daily transportation and storage. The ground projection mechanism 13 projects a landing circle to the ground when the drone arrives and hovers to warn pedestrians and vehicles to stay away. The infrared sensing detector 14 can only transmit the landing signal after detecting that there is no one in the landing circle below the drone.

[0035] As can be seen from the above, driven by the coaxial twin-rotor mechanism 1, the drone group flies to the accident site. After arriving at the designated location, the drone hovers in the air, and the ground projection mechanism 13 projects a landing circle to the ground to warn others to leave. At the same time, the infrared sensor detector 14 detects whether there are pedestrians under the drone. If so, it continues to wait until there are no pedestrians under each drone of the crew, and transmits a landing signal. The coaxial twin-rotor mechanism 1 controls the drone to descend, and the foldable landing gear 4 slowly opens. At this time, the transmitting end 9 in the laser shooting mechanism 8 emits a laser, which is received by the receiving end 10. The drones are connected in pairs by lasers, and a laser warning circle can be formed by up to six drones. The laser shooting mechanism 8 adopts dual laser coupling technology, and each invisible warning laser corresponds to a visible debugging laser, thereby warning pedestrians not to cross the line. Once a pedestrian or vehicle breaks into the warning circle, the laser is blocked, triggering the alarm light 12 to flash, and the scene is recorded by the camera 11 throughout the process. When the drone is stored, the foldable landing gear 4 is retracted, and the upper rotor 5 and the lower rotor 6 are folded toward the fuselage 3.
