Description

Technical Field

[0001] The present invention relates to the field of drones, and in particular to a drone image intelligent recognition device and a method for using the device. Background Art

[0002] To address collision risks in complex operating environments, some current inspection drones add fixed protective structures (such as annular guards or mesh covers) to the periphery of the rotors. This design reduces the probability of direct contact between the rotors and obstacles through physical isolation, while also improving the safety of personnel operating at close range. However, the introduction of protective structures significantly increases the overall size and weight of the drone, resulting in reduced aerodynamic efficiency, shortened flight time, and limiting its maneuverability in confined spaces (such as gaps between photovoltaic panels and in booster station equipment areas). Therefore, another type of drone chooses to eliminate rotor protection and optimize flight performance through a lightweight and compact design, but this also sacrifices the active protection capabilities of the rotors.

[0003] For drones without rotor protection structures, when the rotor continues to rotate due to inertia after landing, the high-speed rotating exposed blades can easily cause accidental injury to personnel or surrounding equipment. Even if the rotor is stationary, the exposed fragile blades may still be damaged by scratches, falls or collisions with foreign objects in complex terrain, affecting the execution of subsequent missions. In addition, the rotor acceleration process during takeoff also poses safety hazards.

[0004] Therefore, there is an urgent need to develop an inspection drone with dynamic protection capabilities, which can automatically deploy the rotor protection device during takeoff and landing, and retract it during flight to eliminate interference with aerodynamic efficiency, thereby achieving a dynamic balance between safety protection and flight performance.

[0024] like Figures 8-10 As shown, in order to accelerate the stopping of the rotor 4 when landing, the lower end of the motor shaft 26 is also set to protrude from the end of the rotor motor 11, and a brake groove 25 corresponding to the motor shaft 26 is provided at one end of the sliding rod 10. The lower end of the motor shaft 26 extends to the inner side of the brake groove 25, and the side wall of the inner cavity of the brake groove 25 is provided with a recess 27.

A second elastic member 29 is provided between one side of the brake strip 28 and the inner wall of the recess 27. The second elastic member 29 is preferably a spring. The brake strip 28 is provided with an inclined surface 30 at one end close to the second protective plate 6. The setting of the inclined surface 30 facilitates the motor shaft 26 to enter the side of the brake strip 28.

[0025] like Figure 12 As shown, as an embodiment of the present application, the telescopic rod 34 is set as a damping rod, and the outer sleeve of the damping rod is provided with a buffer spring 36, which can buffer the damage caused by rigid impact when landing, and the damping rod and the buffer spring 36 are configured as follows: when the rotor 4 is completely stopped, one end of the pressure sensor 35 is in contact with the side of the drone body 1.

[0026] The present application also includes an embodiment, specifically a method for using a drone image intelligent recognition device, comprising the following steps: Step 1: When the drone body 1 is in the air, the telescopic rod 34 is in an extended state, the landing gear 2 is at the farthest distance from the drone body 1, and there is a gap between the pressure sensor 35 and the side of the landing gear 2. At this time, the drive mechanism controls the extension component to be hidden in the side wall of the arm 3; Step 2: When the drone body 1 falls back to the ground, the landing gear 2 first contacts the ground and is pressurized, so that the telescopic rod 34 contracts, and the pressure sensor 35 contacts the side of the drone body 1. The pressure sensor 35 transmits a signal to the drive mechanism, and then the drive mechanism controls the extension component to extend and open to protect the rotor 4.

[0027] The detailed working principle of the optimal embodiment of the present application is as follows: when the drone body 1 is in the air, under the deadweight of the landing gear 2 and the reverse force of the buffer spring 36, the telescopic rod 34 is in an extended state. At this time, the distance between the landing gear 2 and the drone body 1 is the largest, and the pressure sensor 35 is separated from the side of the drone body 1. At this time, the third protective plate 38 is hidden in the first protective plate 5, and the first protective plate 5 and the second protective plate 6 are both fitted and hidden in the side of the arm 3. When landing, the landing gear 2 first contacts the ground, and then the landing gear 2 is pressurized, the telescopic rod 34 contracts, and the buffer spring 36 is compressed, which can play a buffering role and reduce the damage and vibration caused by rigid contact when landing. One end of the pressure sensor 35 is in contact with the drone The side distance of the machine body 1 is reduced until contact occurs, and then the pressure sensor 35 transmits a signal to the driving source 31, and the driving source 31 drives the turntable 37 to rotate, and the turntable 37 drives the traction arm 12 to move outward through the cooperation of the second guide groove 33 and the second guide block 32, and then the traction arm 12 drives the sliding rod 10 to move outward, and the sliding rod 10 drives the sliding rack 15 and the gear 16 to move synchronously, and because one side of the gear 16 is engaged with the fixed rack 17, the sliding rack 15 will drive the connecting seat 14 and the sliding rod 10 to move relative to each other while the sliding rod 10 pushes the second protective plate 6 to move outward, and the connecting seat 14 drives the first protective plate 5 to gradually move through the support rod 9. The first and second protective plates 5 and 6 are unfolded until the first and second protective plates 5 and 6 are displaced to the periphery of the rotor 4. When the sliding rod 10 is displaced, the motor shaft 26 will gradually pass through the inclined surface 30 and enter the side of the brake strip 28. The brake strip 28 is compressed and compresses the second elastic member 29, so that the brake strip 28 generates resistance to the motor shaft 26, thereby accelerating the stopping of the motor shaft 26. In addition, when the first protective plate 5 is gradually stretched and opened, the roller 23 at one end of the driving arm 18 will come into contact with the extrusion sheet 24. As the first protective plate 5 is flipped open, the driving arm 18 is displaced. The driving arm 18 drives the third protective plate 38 to rise through the cooperation of the first guide block 19 and the first guide groove 20. The first elastic member 22 contracts, and the third protective plate 38 rises to a position higher than the rotor. Wing 4, thereby further increasing the protection effect and safety; when taking off again, the landing gear 2 gradually separates from the ground, and can actively control the operation of the drive source 31 through the terminal, or can use the signal when the pressure sensor 35 is separated from the side of the drone body 1 to automatically realize the operation of the drive source 31, and then under the operation of the drive source 31, the traction arm 12 drives the sliding rod 10 to retract, the sliding rod 10 drives the second protective plate 6 to retract, and the sliding rack 15 is reset. Under the action of the first elastic member 22, the third protective plate 38 falls into the first protective plate 5 and is hidden. Then the first protective plate 5, the second protective plate 6, and the strut 9 are gradually recovered and hidden on the side of the arm 3, and then the inspection and video operation is carried out through the intelligent camera device 7.
