Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a mechanism for setting up lifting points for high-voltage power towers using UAVs. Background Technology

[0002] Currently, drones are widely used in various fields such as power line inspection. Drones come in various types, including those with open flight control systems and those without, and those with and without mounting points. Drone control is achieved through its flight control system. Some drones have open flight control systems with interfaces for connecting external devices, such as payload droppers. The drone and payload dropper can be directly controlled via the drone's remote controller. However, drones with closed flight control systems cannot control payload droppers through their flight control system. The application range of drones without mounting points or with closed flight control systems is severely limited. Existing payload droppers have poor versatility and cannot meet the requirements of various types of drones.

[0003] With the rapid development of science and technology, electricity has been widely used in various industries. After years of catching up and surpassing, my country's power transmission technology has reached the international leading level, and the length of its transmission lines ranks first in the world. Due to my country's vast territory and the different regions where power production and consumption are concentrated, a large number of high-voltage transmission lines are needed to transport electricity, resulting in the construction of many high-voltage power towers. To ensure the normal transmission of electricity, power maintenance personnel often need to climb the towers for maintenance work. Currently, maintenance personnel need to continuously and alternately move the safety rope anchor point upwards to ensure safety when climbing the towers. However, due to the limited reach of a person's arms, the safety rope anchor point can only be hung slightly above the head each time, and the suspension height is far below the safety standard, posing a significant safety hazard.

[0004] With the rapid development of drone technology, utilizing drones to pre-suspend safety hooks and attaching fall-prevention ropes to them for connection with power maintenance personnel can fully meet safety requirements. Specifically, the drone hook enables the lifting and transportation of the drone lifting point setting mechanism, thus facilitating its suspension and dismantling. However, existing drone lifting point setting mechanisms are complex in structure and inconvenient to use, representing a problem that needs to be solved by those in the field. Utility Model Content

[0005] To address the problem that existing lifting point mechanisms are inconvenient to use, this utility model provides a mechanism for setting lifting points on high-voltage power towers using drones.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A mechanism for setting up lifting points on a high-voltage power tower using a drone includes a drone lifting ring and a tilting component. The bottom of the drone lifting ring has an anti-detachment component, and the drone lifting ring is connected to a frame structure via the anti-detachment component. One side of the tilting component is connected to a stainless steel pin, and the tilting component is rotatably connected to one side of the frame structure via the stainless steel pin. The tilting component includes a boom, and one side of the boom is equipped with a connecting seat. One side of the connecting seat is inserted into one end of the stainless steel pin. Bending points are provided on both sides of the boom, and one end of the boom has a notch / slot that engages with the anti-detachment component. The anti-detachment component moves up and down between the frame structures via a sliding groove. After the tilting component closes, the anti-detachment component engages with the notch / slot of the tilting component, locking the tilting component. The tilting component automatically opens under gravity, reaching its maximum opening position after contacting a limit pin.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] Before using the drone hoisting mechanism provided by this utility model, the power grid insulating rope is first hung on the rope hoisting point. The drone then directly hangs the hoisting mechanism on the high-voltage power tower profile. Subsequently, the drone descends until it detaches, and the hoisting mechanism contacts the high-voltage power tower profile under gravity. The flipping component flips to form a closure, and the anti-detachment component falls and locks into the slot of the flipping component, forming a self-locking mechanism. The entire process requires no personnel to assist at high altitudes, reducing the labor intensity of operators and effectively improving the safety of this operation method.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a mechanism for setting up lifting points on high-voltage power towers using drones, including a drone lifting ring 1 and a flipping component 3. The bottom end of the drone lifting ring 1 is provided with an anti-detachment component 6. The drone lifting ring 1 is connected to a frame structure 2 through the anti-detachment component 6. One side of the flipping component 3 is connected to a stainless steel pin 9. The flipping component 3 is rotatably connected to one side of the frame structure 2 through the stainless steel pin 9. The flipping component 3 includes an arm 31. A connecting seat 32 is installed on one side of the arm 31. One side of the connecting seat 32 is inserted and connected to one end of the stainless steel pin 9. Bending points are provided on both sides of the arm 31. One end of the arm 31 has a notch and slot that engages with the anti-detachment component 6. First, the power grid insulation rope is hung on the rope lifting point. The drone directly hangs the lifting point mechanism on the high-voltage power tower profile. Then, the drone descends until it is unhooked. The lifting point mechanism contacts the high-voltage power tower profile under gravity. The flipping component 3 flips to form a closed loop. The anti-detachment component 6 falls and engages in the notch and slot of the flipping component 3, forming a self-locking mechanism.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] As an embodiment of this utility model, the frame structure 2 is further provided with a plurality of frame connectors 4 inside, and the two ends of the plurality of frame connectors 4 are respectively threaded with fixing bolts 5. The frame connectors 4 are connected to the frame structure 2 through the fixing bolts 5, which is used to improve the overall structural strength of the frame structure 2. A hollow groove 8 is provided on one side of the frame structure 2 to reduce local weight.

[0019] As an embodiment of the present invention, the anti-detachment component 6 further includes an insert block 61 and a pair of locking blocks 62. Each of the adjacent sides of the pair of locking blocks 62 is provided with a locking groove that slides against the insert block 61. Each of the two sides of the pair of locking blocks 62 is threaded with a screw 63. The locking blocks 62 are connected to the frame structure 2 by the screws 63. The bottom end of the insert block 61 matches the notch and locking groove.

[0020] As an embodiment of this utility model, the top surface of the plug 61 is provided with an insertion port that matches the drone lifting ring 1, which facilitates the precise docking of the drone lifting ring 1. Secondly, the bottom of the frame structure 2 is equipped with a rope lifting point 7, which facilitates connection with the power grid special insulating rope.

[0021] As an embodiment of this utility model, the frame structure 2 is further provided with a limiting pin 10 on the side near the connecting seat 32. After touching the limiting pin 10, it reaches the maximum opening position. There is a gap between the frame connector 4 and the flipping member 3. After the flipping member 3 is closed, it prevents it from over-flipping.

[0022] Specifically, the working principle of this type of high-voltage power tower using a drone-mounted lifting point mechanism is as follows: In use, the power grid insulation rope is first hung on the rope lifting point 7 at the bottom of the frame structure 2. The operator controls the drone to lift the lifting point mechanism to the high-voltage power tower via the drone lifting point 1, and then hangs the lifting point mechanism on the high-voltage power tower profile. Subsequently, the drone descends, and when the lifting point mechanism contacts the high-voltage power tower profile, under the action of gravity, the flipping component 3 rotates around the stainless steel pin shaft 9, and its arm 31 flips at the bending point to form a closed state. At this time, the insert 61 in the anti-detachment component 6 falls, and because its bottom end matches the notch groove at one end of the arm 31, it engages, achieving self-locking and firmly fixing the lifting point mechanism to the high-voltage power tower profile, providing a reliable connection point for subsequent operations. Inside the frame structure 2, the frame connectors 4 are connected to each other by fixing bolts 5, which enhances the overall structural strength, while the hollow grooves 8 reduce local weight; the pair of locking blocks 62 of the anti-detachment component 6 are connected to the frame structure 2 by screws 63, and the insertion port on the top surface of the insertion block 61 facilitates precise docking with the drone lifting ring 1; the limiting pin 10 on the side of the frame structure 2 near the connecting seat 32 can limit the maximum opening position of the flipping component 3, and the reserved gap between the frame connectors 4 and the flipping component 3 can prevent the flipping component 3 from over-flipping after closing, ensuring that the entire mechanism operates stably, safely and reliably.
