Description

Technical Field

[0001] The present invention relates to the technical field of UAV inspection, and particularly relates to a UAV inspection device. Background Art

[0002] A UAV is an unpiloted aircraft mainly controlled by radio remote control or its own program. With the advancement of the intelligent construction of the power system, UAV inspection has become an important means to ensure the safe operation of transmission lines. In traditional UAV inspection devices, detection devices such as cameras are fixed to the UAV fuselage by bolts. However, during inspection in complex terrains, when different detections such as wide-angle shooting are required, since the camera is usually installed below the UAV fuselage, the UAV fuselage is likely to block the shooting angle of the camera. Secondly, when the exposed camera takes off or lands on the ground, it is prone to be contaminated by water stains, dust, or even bumped. Summary of the Invention

[0003] The main purpose of the present invention is to provide a UAV inspection device, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0005] A UAV inspection device includes a UAV main body. A control mechanism is arranged at the lower end of the UAV main body. A shooting pan-tilt is installed inside the control mechanism. A inspection camera is installed on the shooting pan-tilt. The control mechanism includes a storage box fixedly arranged at the lower end of the UAV main body. An air vent is formed on one side of the storage box. A right-angle partition is fixedly arranged inside the storage box. A driving motor is fixedly installed on the upper inner wall of the storage box. One end of the rotating shaft of the driving motor is fixedly provided with a threaded rod. An activity frame is sleeved on one side of the threaded rod close to the air vent. A moving frame is fixedly arranged at the lower end of the activity frame. Two groups of racks are fixedly arranged at the lower end of the moving frame. Sliding grooves are formed at the upper and lower ends of the moving frame near the front and rear sides. Two groups of activity openings are formed at the position corresponding to the activity frame on the lower side of the air vent. A plurality of groups of fixed shafts are fixedly arranged on the inner walls of the front and rear sides of the storage box. Rollers are rotatably arranged on the outer sides of the plurality of groups of fixed shafts.

[0006] Preferably, a connecting shaft is rotatably arranged on the lower side of the storage box. A right-angle baffle is fixedly arranged on the outer side of the connecting shaft. Two sets of round wheels are fixedly arranged on the outer side of the connecting shaft. A plurality of sets of tooth grooves are arranged on the inner sides of the two sets of round wheels. Notches are arranged at the positions corresponding to the two sets of round wheels on the lower side of the storage box. The position where the upper end of one side of the right-angle baffle is in contact with the storage box is provided with an inclined surface. A groove is arranged at the position corresponding to the right-angle partition on the lower side of the storage box. A positioning elastic piece is fixedly arranged at a position close to one side edge of the lower end of the storage box. A positioning card strip is fixedly arranged on the lower side of the positioning elastic piece. A positioning card slot is arranged at a position close to the lower side of one end of the right-angle baffle. Two ventilation components are arranged inside the right-angle baffle.

[0007] Preferably, each ventilation component includes a round tube fixedly arranged inside the right-angle baffle. A grille is fixedly arranged at the bottom of the round tube. A sleeve is fixedly arranged on the inner wall of the round tube. A first fan head is rotatably arranged inside the sleeve. A large bevel gear is fixedly arranged at one end of the first fan head close to the inner side of the round tube. A cross is fixedly arranged inside the upper part of the round tube. A second fan head is rotatably arranged inside the cross. A small bevel gear is fixedly arranged at the lower end of the second fan head.

[0008] Preferably, the right-angle partition separates the shooting cloud platform from the driving motor. The movable frame is in threaded connection with the threaded rod. The movable frame slides through the inside of the movable opening.

[0009] Preferably, the movable frame is arranged at the lower side position of the air vent. The sliding grooves formed at the upper and lower ends of the movable frame correspond to the rollers on the front and rear inner walls of the storage box. The rollers roll in the sliding grooves formed at the upper and lower sides respectively.

[0010] Preferably, the right-angle baffle is arranged at a corner on the lower side of the storage box. The two sets of round wheels respectively correspond to the two sets of racks. The upper sides of the round wheels partially pass through the inside of the notches.

[0011] Preferably, the round wheels and the racks are in a meshed state in the initial state through the tooth grooves. The groove is adapted to allow the ventilation component to enter driven by the rotation of the right-angle baffle. The positioning card strip is adapted to the positioning card slot.

[0012] Preferably, the round tube is communicated with the inside of the storage box. The large bevel gear and the small bevel gear are in a meshed state.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By starting the drive motor to drive the threaded rod to rotate, the movable frame and the moving frame connected by the thread are driven to move towards the right-angle baffle. The movable frame and the moving frame slide respectively between the movable opening and several groups of rollers, and the inspection camera installed at the upper end of the moving frame extends outwards from the storage box. At the same time, the two racks respectively drive the two sets of round wheels engaged with them to rotate, and the inspection camera is moved outwards and extended, avoiding the situation that the body blocks the camera and affects the shooting of the camera, thereby improving the practicability of the drone and expanding the applicable range of the drone.

[0015] 2. When the two racks drive the two sets of round wheels to rotate, the two sets of round wheels will drive the fixedly connected connecting shaft and the right-angle baffle to rotate 180 degrees towards the air vent. After the inspection camera moves out, the purpose of automatically opening the outlet is realized. At this time, the positioning card slot on the right-angle baffle contacts the positioning card strip, and under the elastic action of the positioning elastic piece, they are clamped together to position the right-angle baffle, avoiding the two racks from disengaging from the two sets of round wheels under the continuous movement of the moving frame, and the right-angle baffle automatically falls under its own weight and swings under the influence of air flow during flight, resulting in unstable flight of the drone body. After driving the inspection camera to retract, the rack will drive the round wheel to rotate again, driving the right-angle baffle to disengage from the positioning card strip, closing one side of the storage box, avoiding rain during flight, and preventing the inspection camera lens from being contaminated by blown-up dirt or dust when taking off or stopping on the ground, improving the cleanliness and safety of the inspection camera itself.

[0016] 3. When the inspection camera gets wet with rain, the closed right-angle baffle will drive the two round tubes towards the air flow direction. The air flow during flight will blow the two first fan heads to rotate, driving the engaged small bevel gear to rotate through the connected large bevel gear, so that the second fan head rotates, extracting air from the lower side and blowing it towards the internal inspection camera, accelerating the drying of the inspection camera and the interior, avoiding the formation of water droplets or water mist on the lens surface, resulting in blurred, halo or refraction of the shooting image, and improving the protection of the equipment.

Detailed implementation manners

[0026] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0027] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is the relative orientation or positional relationship, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0028] Please refer to Figures 1-8, an embodiment provided by the present invention: an unmanned aerial vehicle inspection device, including an unmanned aerial vehicle main body 1, a control mechanism 2 is arranged at the lower end of the unmanned aerial vehicle main body 1, a shooting pan-tilt 3 is installed inside the control mechanism 2, and an inspection camera 4 is installed on the shooting pan-tilt 3. The control mechanism 2 includes a storage box 21 fixedly arranged at the lower end of the unmanned aerial vehicle main body 1, a ventilation opening 22 is arranged on one side of the storage box 21, a right-angle partition 23 is fixedly arranged inside the storage box 21, a driving motor 24 is fixedly installed on the upper inner wall of the storage box 21, one end of the rotating shaft of the driving motor 24 is fixedly provided with a threaded rod 25, a movable frame 26 is sleeved on the side of the threaded rod 25 close to the ventilation opening 22, a movable frame 27 is fixedly arranged at the lower end of the movable frame 26, two groups of racks 28 are fixedly arranged at the lower end of the movable frame 27, sliding grooves 29 are arranged at the upper and lower ends of the movable frame 27 near the front and rear sides, and two groups of movable openings 210 are arranged at the position corresponding to the movable frame 26 on the lower side of the ventilation opening 22. Fixed shafts 211 are fixedly arranged on the front and rear inner walls of the storage box 21, and rollers 212 are rotatably arranged on the outer sides of the plurality of fixed shafts 211.

[0029] The right-angle partition 23 separates the shooting pan-tilt 3 from the driving motor 24. The movable frame 26 is in threaded connection with the threaded rod 25. The movable frame 26 slides through the inside of the movable opening 210. The movable frame 27 is arranged at the lower side position of the ventilation opening 22. The sliding grooves 29 opened at the upper and lower ends of the movable frame 27 correspond to the rollers 212 on the front and rear inner walls of the storage box 21, and the rollers 212 roll in the upper and lower sliding grooves 29 respectively.

[0030] By starting the driving motor 24 to drive the threaded rod 25 to rotate, the movable frame 26 and the movable frame 27 in threaded connection are driven to move towards the right-angle baffle 214. The movable frame 26 and the movable frame 27 slide between the movable opening 210 and the plurality of rollers 212 respectively, and the inspection camera 4 installed at the upper end of the movable frame 27 is extended out of the storage box 21. At the same time, the two groups of racks 28 respectively drive the two groups of round wheels 215 engaged therewith to rotate, and the inspection camera 4 is moved and extended outwards, avoiding the situation that the body blocks the camera and affects the camera shooting, thereby improving the practicability of the unmanned aerial vehicle and expanding the applicable range of the unmanned aerial vehicle.

[0031] A connecting shaft 213 is rotatably arranged on the lower side of the storage box 21. A right-angle baffle 214 is fixedly arranged on the outer side of the connecting shaft 213. Two sets of round wheels 215 are fixedly arranged on the outer side of the connecting shaft 213. A number of tooth grooves 216 are formed on the inner sides of the two sets of round wheels 215. Notches 217 are formed at the positions corresponding to the two sets of round wheels 215 on the lower side of the storage box 21. The position where the upper end of one side of the right-angle baffle 214 is in contact with the storage box 21 is set as an inclined surface 218. A groove 219 is formed at the position corresponding to the right-angle partition 23 on the lower side of the storage box 21. A positioning elastic piece 220 is fixedly arranged at a position close to one side edge at the lower end of the storage box 21. A positioning card strip 221 is fixedly arranged on the lower side of the positioning elastic piece 220. A positioning card slot 222 is formed at a position close to the lower side at one end of the right-angle baffle 214. Two ventilation components 223 are arranged inside the right-angle baffle 214.

[0032] The right-angle baffle 214 is arranged at a corner on the lower side of the storage box 21. The two sets of round wheels 215 respectively correspond to the two sets of rack bars 28. The upper sides of the round wheels 215 partially pass through the interiors of the notches 217. The round wheels 215 and the rack bars 28 are initially meshed through the tooth grooves 216. The groove 219 is adapted to drive the ventilation components 223 to enter when the right-angle baffle 214 rotates. The positioning card strip 221 is adapted to the positioning card slot 222.

[0033] When the two sets of rack bars 28 drive the two sets of round wheels 215 to rotate, the two sets of round wheels 215 will drive the fixedly connected connecting shaft 213 and right-angle baffle 214 to rotate 180 degrees towards the air vent 22. After the inspection camera 4 moves out, the purpose of automatically opening the outlet is achieved. At this time, the positioning card slot 222 arranged on the right-angle baffle 214 contacts the positioning card strip 221. Under the elastic action of the positioning elastic piece 220, they are clamped together to position the right-angle baffle 214, avoiding the two sets of rack bars 28 from disengaging from the two sets of round wheels 215 under the continuous movement of the moving frame 27. The right-angle baffle 214 automatically falls under its own weight and swings under the influence of air flow during flight, resulting in unstable flight of the UAV body 1. After driving the inspection camera 4 to retract, the rack bar 28 will drive the round wheel 215 to rotate again, driving the right-angle baffle 214 to disengage from the positioning card strip 221, closing one side of the storage box 21, avoiding rain during flight, and preventing the lens of the inspection camera 4 from being contaminated by blown-up dirt or dust when taking off or stopping on the ground, improving the cleanliness and safety of the inspection camera 4 itself.

[0034] The ventilation component 223 includes a circular tube 2231 fixedly arranged inside the right-angled baffle 214. A grille 2232 is fixedly arranged at the bottom of the circular tube 2231. A sleeve 2233 is fixedly arranged on the inner wall of the circular tube 2231. A first fan head 2234 is rotatably arranged inside the sleeve 2233. A large bevel gear 2235 is fixedly arranged at one end of the first fan head 2234 close to the inner side of the circular tube 2231. A cross 2236 is fixedly arranged inside the upper side of the circular tube 2231. A second fan head 2237 is rotatably arranged inside the cross 2236. A small bevel gear 2238 is fixedly arranged at the lower end of the second fan head 2237.

[0035] The circular tube 2231 communicates with the inside of the storage box 21, and the large bevel gear 2235 and the small bevel gear 2238 are meshed.

[0036] When the inspection camera 4 gets stuck with rain, the closed right-angled baffle 214 will drive the two circular tubes 2231 towards the airflow direction. The airflow during flight will blow the two first fan heads 2234 to rotate. The connected large bevel gear 2235 drives the meshed small bevel gear 2238 to rotate, so that the second fan head 2237 rotates, extracts air from the lower side position and blows it towards the internal inspection camera 4, accelerating the drying of the inspection camera 4 and the inside, avoiding the formation of water droplets or water mist on the lens surface, resulting in blurred, halo or refraction of the captured image, and improving the protection of the device.

[0037] Working principle: When in use, start the driving motor 24 to drive the threaded rod 25 to rotate, driving the movable frame 26 and the moving frame 27 connected by threads to move towards the right-angle baffle 214. The movable frame 26 and the moving frame 27 slide along the movable opening 210 and between several groups of rollers 212 respectively, extending the inspection camera 4 installed at the upper end of the moving frame 27 out of the storage box 21. At the same time, two racks 28 respectively drive two sets of round wheels 215 arranged in meshing to rotate, and move the inspection camera 4 outwards and extend it, avoiding the situation that the body blocks the camera and affects the camera shooting, thereby improving the practicality of the drone and expanding the application range of the drone. In addition, when the two racks 28 drive the two sets of round wheels 215 to rotate, the two sets of round wheels 215 will drive the fixedly connected connecting shaft 213 and the right-angle baffle 214 to rotate 180 degrees towards the air vent 22. After the inspection camera 4 moves out, the purpose of automatically opening the outlet is achieved. At this time, the positioning card slot 222 provided on the right-angle baffle 214 contacts the positioning card strip 221, and under the elastic action of the positioning elastic piece 220, they are engaged with each other to position the right-angle baffle 214, avoiding the two racks 28 from disengaging from the two sets of round wheels 215 under the continuous movement of the moving frame 27, and the right-angle baffle 214 automatically falling under its own weight and swinging under the influence of air flow during flight, resulting in unstable flight of the drone body 1. After driving the inspection camera 4 to retract, the rack 28 will drive the round wheel 215 to rotate again, driving the right-angle baffle 214 to disengage from the positioning card strip 221, closing one side of the storage box 21, avoiding rain during flight, and preventing the inspection camera 4 from being contaminated by blown dirt or dust when taking off or stopping on the ground, improving the cleanliness and safety of the inspection camera 4 itself. Finally, when the inspection camera 4 gets wet with rain, the closed right-angle baffle 214 will drive the two round tubes 2231 towards the air flow direction, and the air flow during flight will blow the two first fan heads 2234 to rotate, driving the engaged small bevel gear 2238 to rotate through the connected large bevel gear 2235, so that the second fan head 2237 rotates, extracting air from the lower side and blowing it towards the internal inspection camera 4, accelerating the drying of the inspection camera 4 and the interior, avoiding the formation of water droplets or water mist on the lens surface, resulting in blurred, haloed or refracted shooting images, and improving the protection of the equipment.

[0038] The drone body 1, driving motor 24, shooting pan-tilt 3, and inspection camera 4 electrical components in the present invention are existing structures in the art, and the usage methods and connection methods between them belong to the common knowledge in this field. Their working principles are already well-known technologies, and the models are selected according to actual use. Therefore, no detailed explanation will be given.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
