Description

Technical Field

[0001] This invention belongs to the technical field of drone mounting devices, and particularly relates to a drone safety inspection mounting device. Background Technology

[0002] Currently, drones are widely used in the power industry and play a significant role in line inspection. When a drone discovers that a power tower needs maintenance during line inspection, the existing technology usually involves manual climbing of the tower to carry out maintenance.

[0003] Typically, maintenance and repair of power transmission towers takes a considerable amount of time. Climbing and descending the towers is time-consuming and dangerous, so workers must bring their tools and food with them. Given the height of power transmission towers, climbing them is inherently dangerous, and carrying a large number of maintenance tools further increases their physical exertion. Furthermore, the subsequent work at heights significantly increases the risks associated with climbing and maintaining the towers.

[0004] The emergence of drone mounting devices allows drones to carry mounting devices and ropes to the top of the tower in advance, making it easier for workers to climb up the safety rope, reducing the degree of danger and improving work efficiency.

[0005] However, when using traditional drone mounting devices, the locking position of the latch and the drone camera are set off-center when they are connected and fixed to the tower beam. It is necessary to manually adjust the drone's hovering position based on the image and the deviation between the latch and the camera before locking the mounting device to the tower beam. This method increases the difficulty of operating the drone and reduces the installation efficiency of the mounting device.

[0006] Therefore, there is an urgent need for a drone safety inspection mounting device to solve this problem. Summary of the Invention

[0007] The purpose of this invention is to provide a drone safety inspection mounting device to solve the above-mentioned problems.

[0008] To achieve the above objectives, the present invention provides the following solution: A drone safety inspection mounting device includes: The lower platform has a vertically sliding movable plate, and a camera and a fill light are fixed at the bottom center of the movable plate; the lower platform is connected to the bottom of the drone, and the camera and fill light are coaxially arranged with the drone. The first bracket and the second bracket are fixed to the bottom sides of the lower platform, respectively. The bottom end of the second bracket is rotatably engaged with the middle part of the C-shaped rotating frame. One end of the C-shaped rotating frame is connected to the motor and the output gear, and the other end of the C-shaped rotating frame is in transmission engagement with the movable plate. The first bracket is connected to a rope winding assembly, and the rope winding assembly is connected to one end of a rope; The camera and fill light are connected to the drone via a flexible data cable; After the drone takes off, it aligns with the target beam using the camera and fill light, and descends vertically directly above the target beam. Once the movable plate contacts the top of the target beam, it pushes the C-shaped rotating frame to rotate, causing the motor and output gear to approach the rope winding assembly and engage in transmission. At this time, the first bracket, the C-shaped rotating frame, and the lower platform together form a locking space.

[0009] Optionally, the top of the movable plate is fixed with the bottom end of a sliding rod, the sliding rod is vertically slidably connected to the lower platform, and the top end of the sliding rod is fixed with a second limiting plate, the second limiting plate being in a limiting engagement with the lower platform.

[0010] Optionally, a drone resting platform is fixed to the top of the lower platform by multiple connecting rods, and the drone resting platform is connected and fixed to the drone by a flexible connecting cable; One end of the flexible data cable passes through the drone rest platform and connects to the drone; The drone rest platform is used for the drone to land.

[0011] Optionally, a first limiting plate is fixed to one side of the bottom end of the movable plate, and the first limiting plate is in a limiting engagement with the end of the C-shaped rotating frame away from the motor and the output gear.

[0012] Optionally, the rope winding assembly includes a rotating wheel and a driven gear fixed coaxially, the rotating wheel and the driven gear being rotatably engaged with the first bracket, and one end of the rope being fixed on the rotating wheel; When the motor and output gear are brought close to the rope winding assembly, the driven gear meshes with the output gear of the motor and output gear.

[0013] Optionally, a support wheel is rotatably connected to the bottom of the first bracket, and the end of the rope away from the rope winding assembly is wound around the support wheel.

[0014] Optionally, the C-shaped rotating frame and the second support are rotatably coupled by a torsion spring.

[0015] Optionally, the flexible connecting cable is a steel wire rope.

[0016] Optionally, a groove is formed at the center of the bottom of the movable plate, and the camera and fill light are fixed in the groove. The camera is fixed at the top center of the groove, and the fill light consists of multiple LED beads, which are fixed around the inner wall of the groove. The camera is connected to the bottom end of the flexible data cable; The top of the flexible data cable passes sequentially through the slide bar, the drone rest platform, and the bottom of the drone.

[0017] Optionally, a spring is provided between the movable plate and the lower platform, and the spring is sleeved on the outside of the slide rod.

[0018] Compared with the prior art, the present invention has the following advantages and technical effects: This invention uses a camera and supplementary lighting coaxially mounted with the drone, allowing the drone to directly align with the center of the crossbeam via the camera image during descent. This eliminates the need for manual adjustments to the hovering position based on eccentricity, significantly reducing operational difficulty and positioning time. Upon contact with the crossbeam, the movable plate automatically pushes the C-shaped rotating frame to rotate, engaging the motor and output gear with the rope winding assembly. Simultaneously, the first support, the C-shaped rotating frame, and the lower platform automatically close to form a locking space, achieving rapid and reliable locking of the mounting device to the crossbeam, improving installation efficiency and safety. The entire locking process requires no manual intervention; workers can safely climb using the rope on the rope winding assembly, reducing the burden of carrying tools and food while climbing the tower and lowering the risks of high-altitude operations. The device automatically resets upon unlocking via gravity or spring action, making it easy to operate, highly reusable, and suitable for the rapid operational needs of power tower inspection and maintenance.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1 to 3 This invention discloses a drone safety inspection mounting device, comprising: The lower platform 17 has a vertically sliding movable plate 5, and a camera and a fill light 6 are fixed at the bottom center of the movable plate 5. The lower platform 17 is connected to the bottom of the drone 10, and the camera and fill light 6 are coaxially set with the drone 10. The first bracket 3 and the second bracket 18 are fixed to the bottom sides of the lower platform 17, respectively. The bottom end of the second bracket 18 is rotatably engaged with the middle part of the C-shaped rotating frame 7. One end of the C-shaped rotating frame 7 is connected to the motor and the output gear 14, and the other end of the C-shaped rotating frame 7 is engaged with the movable plate 5 in a transmission manner. A rope winding assembly 15 is connected to the first bracket 3, and one end of a rope 16 is connected to the rope winding assembly 15. The camera and fill light 6 are connected to the drone 10 via a flexible data cable 8; After the drone 10 takes off, it aims at the target beam through the camera and the supplementary light 6, and makes the drone 10 descend vertically directly above the target beam. After the movable plate 5 contacts the top of the target beam, the movable plate 5 pushes the C-shaped rotating frame 7 to rotate, so that the motor and output gear 14 approach the rope winding assembly 15 and engage in transmission. At this time, the first bracket 3, the C-shaped rotating frame 7 and the lower platform 17 enclose and form a locking space 20.

[0023] In use, after the drone 10 takes off carrying the lower platform 17, it aligns the target beam with the camera and supplementary light 6. Since the camera and supplementary light 6 are coaxial with the drone 10, they can be remotely aligned with the top of the beam. When the drone 10 descends vertically, the center of the movable plate 5 contacts the top of the beam. As the movable plate 5 slides vertically with the lower platform 17, the movable plate 5 pushes the C-shaped rotating frame 7 to rotate, causing the first support 3, the C-shaped rotating frame 7, and the lower platform 17 to enclose and form a locking space 20, which encircles the target beam and forms a stable support point. At this time, the worker climbs using the rope 16 on the rope assembly 15. When the work is completed and the device needs to be dismantled, the drone 10 rises vertically. At this time, the movable plate 5 descends relative to the C-shaped rotating frame 7 under the action of gravity. One end of the C-shaped rotating frame 7 is connected to the motor and output gear 14, which allows the C-shaped rotating frame 7 to rotate naturally and return to its initial state. Then the locking space 20 opens, allowing the beam to be removed.

[0024] As an optional implementation, the bottom end of the slide rod 4 is fixed to the top of the movable plate 5. The slide rod 4 is vertically slidably connected to the lower platform 17. The top end of the slide rod 4 is fixed to the second limiting plate 19, and the second limiting plate 19 is in a limiting cooperation with the lower platform 17.

[0025] As the drone descends vertically, the movable plate 5 contacts the crossbeam, pushing the slide bar 4 to slide upward along the lower platform 17. The drone then rises vertically, causing the second limiting plate 19 at the top of the slide bar 4 to be positioned relative to the lower platform 17. Through these settings, the maximum travel of the movable plate 5 is precisely limited, ensuring a stable and reliable locking triggering process and providing stable support for the subsequent rotation of the C-shaped rotating frame 7 and the formation of the locking space 20.

[0026] As an optional implementation, the top of the lower platform 17 is fixed with a drone resting platform 1 by a plurality of connecting rods 2, and the drone resting platform 1 and the drone 10 are connected and fixed by a flexible connecting cable 9; One end of the flexible data cable 8 passes through the drone rest platform 1 and connects to the drone 10; The drone rest platform 1 is used for the landing of drone 10.

[0027] The drone 10 is connected to the drone resting platform 1 via a flexible connecting cable 9. When the drone 10 carrying its equipment is mounted on the crossbeam and supported, the drone 10 can land on the drone resting platform 1 for parking. A flexible data cable 8 passes through the platform and connects to the drone, ensuring smooth data transmission. At the same time, the connecting rod 2 provides a stable connection frame between the drone resting platform 1 and the lower platform 17.

[0028] As an optional implementation, a first limiting plate 12 is fixed to one side of the bottom end of the movable plate 5, and the first limiting plate 12 is matched with the end of the C-shaped rotating frame 7 away from the motor and the output gear 14.

[0029] When the movable plate 5 moves upward due to contact with the crossbeam, the upper surface of the movable plate 5 pushes the end of the C-shaped rotating frame 7 away from the motor and the output gear 14, causing the C-shaped rotating frame 7 to rotate, and the first limiting plate 12 fixed at the bottom of the movable plate 5 restricts the reverse rotation of the C-shaped rotating frame 7.

[0030] As an optional implementation, the rope winding assembly 15 includes a rotating wheel 1501 and a driven gear 1502 that are coaxially fixed. The rotating wheel 1501 and the driven gear 1502 are rotatably engaged with the first bracket 3. One end of the rope 16 is fixed on the rotating wheel 1501. When the motor and output gear 14 approach the rope winding assembly 15, the driven gear 1502 meshes with the output gear of the motor and output gear 14.

[0031] When the drone descends and triggers the lock, the motor and output gear 14 mesh with the driven gear 1502. The motor starts, and the power drives the driven gear 1502 and the coaxial rotating wheel 1501 to rotate through the output gear, thereby controlling the winding and unwinding of the rope 16 wound on it. This design combines the drone's locking action with the rope winding drive into one.

[0032] When items need to be hoisted to the construction position, the motor and output gear 14 can drive the rotating wheel 1501 to rotate and lift the rope 16 to transport the items.

[0033] As an optional implementation, the bottom of the first bracket 3 is rotatably connected to a support wheel 11, and the end of the rope 16 away from the rope winding assembly 15 is wound around the support wheel 11.

[0034] After being led out from the rope winding assembly 15, the rope 16 is wound around the support wheel 11, which is rotatably connected to the bottom of the first bracket 3. The support wheel 11 effectively changes the traction direction of the rope 16 and provides a smooth rolling contact surface for the rope 16. This significantly reduces the frictional resistance and wear of the rope 16 during winding and unwinding, making the movement of the rope 16 smoother.

[0035] As an optional implementation, the C-shaped rotating frame 7 and the second support 18 are rotatably engaged by a torsion spring 13.

[0036] When the C-shaped rotating frame 7 rotates on the second support 18, the torsion spring 13 is twisted to store energy. When the drone 10 rises and detaches from the crossbeam, the torsion spring 13 releases energy, driving the C-shaped rotating frame 7 to automatically return to its initial position, ensuring that the locking space 20 is reliably unlocked.

[0037] As an optional implementation, the flexible connecting cable 9 is a steel wire rope.

[0038] As an optional implementation, a groove is opened at the bottom center of the movable plate 5, and the camera and the fill light 6 are fixed in the groove. The camera is fixed at the top center of the groove, and the fill light consists of multiple LED beads, which are fixed around the inner wall of the groove. The camera is connected to the bottom end of the flexible data cable 8; The top of the flexible data cable 8 passes through the slide bar 4, the drone rest platform 1, and the bottom of the drone 10 in sequence.

[0039] As an alternative implementation, a spring is provided between the movable plate 5 and the lower platform 17, and the spring is sleeved on the outside of the slide rod 4.

[0040] The spring sleeved on the outside of the slide bar 4 is compressed and stores energy when the movable plate 5 contacts the crossbeam and rises, providing power for the automatic reset of the movable plate 5 and the smooth separation of the lower platform 17 when the UAV 10 is withdrawn, thus enhancing the smoothness and reliability of the locking and unlocking actions.
