Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to an active sealing trolley for using UAVs to hook up overhead power transmission lines. 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] During the operation of power transmission lines, due to the influence of the external environment, problems frequently occur such as broken or loose strands of conductors and ground wires, failure or missing bolts and pins, deformation or damage of auxiliary facilities, displacement or wear of hardware, and loosening or disconnection of connection points. To ensure the safe and stable operation of power transmission lines and uninterrupted power supply, live-line working is usually used to repair the defects in the power transmission lines.

[0004] To change the physically demanding and high-intensity work conditions of power transmission line maintenance, reduce labor intensity, improve maintenance efficiency, and usher in an era of intelligent and lightweight tools for live-line work, this method fully utilizes drones combined with electric lifting devices to further enhance the energy efficiency of electric lifting devices. This method avoids workers climbing rope ladders and towers, minimizing labor intensity, improving maintenance efficiency, shortening maintenance time, reducing power outage time, and improving the economic benefits of the power grid, thus achieving the goals of reducing labor intensity and making tools intelligent and lightweight.

[0005] The drawback of existing attachment point setting mechanisms is their complex structure. When the drone attaches it to the guide wire, it will move relative to the guide wire under the action of the traveling pulley, which is not suitable for situations where the trolley needs to be set at a fixed point. Utility Model Content

[0006] This invention provides an active sealing trolley for using a drone to hook onto an overhead power transmission line, overcoming the shortcomings of existing technologies. Employing a purely mechanical structure, it allows the trolley to actively seal itself by applying a load after the drone reaches the overhead line. This overcomes the uncertainty of other trolley structures that rely on gravity to create a closed space, effectively preventing the lifting point mechanism from accidentally detaching from the overhead power transmission line and ensuring personnel safety. After use, the drone hook hooks the lifting point mechanism via the drone's lifting ring structure, and the flipping component automatically opens under the action of a torsion spring, allowing the overhead power transmission line to detach. No additional operation is required during the process, ensuring high reliability.

[0007] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0008] An active sealing trolley for attaching to overhead power transmission lines using a drone includes a drone lifting ring, a tilting component, and a rope sling. The bottom of the drone lifting ring is rigidly connected to a frame structure. One end of the tilting component is fitted with a shouldered hinge pin, which rotatably connects the tilting component to the bottom of the frame structure. Torsion springs are fitted to both ends of the shouldered hinge pin, with one end of each spring connected to one side of the frame structure. A groove is provided on one side of the tilting component to engage with the two torsion springs. A stainless steel pin is inserted into one side of the rope sling, which connects to one end of the tilting component. After the drone attaches the active sealing trolley to the overhead power transmission line, a certain load is applied via the rope connected to the rope sling, causing the tilting component to close the opening in the frame structure, thus actively sealing the trolley mechanism.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This type of active closure pulley system, which uses a drone to hook onto an overhead power transmission line, first attaches the power grid insulation rope to a suspension point. The drone then directly hooks the pulley mechanism onto the overhead power line. The operator manually applies a load to the rope, causing the tilting mechanism to flip under tension and form a closure with the frame structure. The drone then descends until it detaches. The entire process requires no personnel assistance at height, reducing the labor intensity of workers and avoiding severe rope wear, thus effectively improving the safety of this operation method.

[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] Please see Figures 1-4 This utility model provides a technical solution: an active enclosure trolley for hooking up overhead power transmission lines using a drone, comprising a drone lifting ring 1, a flipping component 3, and a rope lifting point 4. The bottom of the drone lifting ring 1 is rigidly connected to a frame structure 2. One end of the flipping component 3 is equipped with a shoulder hinge pin 7, which rotatably connects the flipping component 3 to the bottom end of the frame structure 2 via the shoulder hinge pin 7. Torsion springs 5 ​​are respectively fitted at both ends of the shoulder hinge pin 7, with one end of each torsion spring 5 connected to one side of the frame structure 2. A groove is provided on one side of the flipping component 3 to engage with the two torsion springs 5. The rope... A stainless steel pin 6 is inserted on one side of the lifting point 4. The rope lifting point 4 is connected to one end of the flipping part 3 through the stainless steel pin 6. The trolley mechanism is suitable for use during live work. The operator uses a drone to hang the trolley mechanism on the overhead power line. The load is manually applied by the special insulated rope of the power grid, so that the flipping part and the frame structure form a closed loop. After the operator completes the designated operation on the overhead power line, the load on the special insulated rope of the power grid is manually unloaded. At this time, the flipping part automatically flips under the action of the torsion spring, opening the frame structure. The operator then uses the drone to retrieve the trolley mechanism.

[0019] 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.

[0020] As an embodiment of this utility model, the rigid connection between the drone lifting ring 1 and the frame structure 2 is set as welding. The frame structure 2 is an integrally formed part with a hollow cavity inside, which reduces the load and increases efficiency. The drone lifting ring 1, the frame structure 2 and the flipping part 3 are all made of aluminum alloy, which is lightweight and portable.

[0021] As an embodiment of this utility model, the two torsion springs 5 ​​are symmetrical about the flipping member 3 to ensure uniform force on the left and right sides. One end of the torsion spring 5 is set as a U-shaped structure, and the U-shaped structure is snapped into the frame structure 2.

[0022] As one embodiment of this utility model, the rope suspension point 4 is further designed as a universal joint structure, which can rotate freely after being connected to the power grid-specific insulating rope.

[0023] Specifically, the working principle of this type of active sealing trolley for using a drone to lift overhead power transmission lines is as follows: During operation, the operator controls the drone to lift the trolley mechanism to the overhead power transmission line via the drone's lifting ring 1, and then hangs it on the line. Subsequently, a load is manually applied using a special insulated rope for the power grid. The tension of the load causes the flipping component 3 to overcome the elasticity of the torsion spring 5 and rotate around the shouldered hinge pin 7, forming a seal with the frame structure 2. This securely hangs the trolley on the overhead power transmission line, facilitating the operator's designated operations. After the operation is completed, the load on the special insulated rope for the power grid is manually removed. At this point, the torsion spring 5 returns to its original deformation and uses its own elasticity to automatically flip the flipping component 3, opening the frame structure 2. Finally, the operator again controls the drone to retrieve the trolley mechanism via the drone's lifting ring 1. Among them, the drone lifting ring 1 is welded to the frame structure 2, and the frame structure 2 is integrally formed and hollow inside. In addition, the drone lifting ring 1, frame structure 2 and flipping part 3 are all made of aluminum alloy, which reduces the overall weight of the trolley and improves the work efficiency. The torsion springs 5 ​​are symmetrically arranged and have a U-shaped structure at one end to ensure that the flipping part 3 is evenly stressed and has stable reset. The universal joint structure of the rope lifting point 4 allows it to rotate freely after being connected to the special insulated rope for the power grid, adapting to complex working environments and ensuring smooth loading and unloading of loads.
