Description

Technical Field

[0001] The utility model relates to the technical field of power transmission line maintenance, in particular to an auxiliary hanging and dismantling device for unmanned aerial vehicles with high-altitude operation orientation and anti-sway functions. Background Art

[0002] During high-altitude maintenance and emergency rescue operations of ultra-high voltage (UHV) transmission lines, it is generally necessary to install temporary hanging points or other permanent monitoring devices and safety protection devices on the conductors, ground wires, and angle steels at the top of the towers. These devices are generally transfer pulleys, rope hanging points, monitoring devices, etc.

[0003] The traditional installation method mainly uses personnel to carry the equipment to the tower for installation. With the rapid development of drone technology, at this stage, high-altitude maintenance and emergency rescue operations of ultra-high voltage (UHV) transmission lines are gradually using drones to assist in installation to replace the traditional tower-climbing installation method. The advantage of using drones to assist in high-altitude installation is that it can greatly improve work efficiency and reduce labor intensity.

[0004] However, the existing drone-assisted assembly and disassembly technology is still immature, and there are many problems in actual operations: 1. The installation is difficult and risky: Ultra-high voltage (UHV) transmission lines are about 50 meters above the ground, and some are even hundreds of meters above the ground. The lines are numerous and complex, and operations are generally carried out in a live environment. Affected by strong electric field interference, drones must be at least 2 meters away from the wires to operate normally. The closer to the wires, the greater the risk of crashing, which brings great difficulties to high-altitude installation; 2. The drone's mounting weight is limited: At this stage, most of the drones used for high-altitude maintenance of ultra-high voltage (UHV) transmission lines are They are all small four-rotor drones, which are easy to carry and operate in the field. Their load capacity is about 5kg or less. Given their small load capacity, the weight of the auxiliary hanging and disassembly device cannot be too heavy, otherwise it will not be able to support the drone operation; 3. The hanging and disassembly accuracy is low and the operating conditions are complex: Since the drone needs to be a certain distance away from the wire, the structural length of its hanging and disassembly device is about 2 meters or more. Affected by the high-altitude wind and the downward wind force of the drone propeller, the hanging and disassembly device is prone to non-directional swinging and shaking during operation, resulting in low high-altitude assembly and disassembly accuracy and a long time consumption, which brings great difficulties to the drone operator's operation.

[0005] To this end, a UAV auxiliary mounting and dismounting device with high-altitude operation orientation and anti-swaying functions is proposed to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the present invention is to provide an auxiliary mounting and dismounting device for a UAV with high-altitude operation orientation and anti-sway functions, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an auxiliary hanging and dismantling device for unmanned aerial vehicles with high-altitude operation orientation and anti-swaying functions, comprising an unmanned aerial vehicle and a flexible traction rope, wherein the lower side wall of the unmanned aerial vehicle is fixedly provided with symmetrical fixing rods, and the upper ends of the two flexible traction ropes are provided with movable locks, and the upper ends of the flexible traction ropes are fixed to the outside of the fixed rods through the movable locks, and the outsides of the lower ends of the two flexible traction ropes are provided with hanging and dismantling rings, and the lower ends of the hanging and dismantling rings are jointly fixed with hooks, and the lower ends of the hooks are fixed with wind-fixing wing plates.

[0008] Preferably, the hook is in a "V" shape.

[0009] Preferably, the side wall of the wind-fixing wing plate is provided with an air guide hole.

[0010] Preferably, the two flexible traction ropes are slidably connected to the inside of the two hanging and detaching rings.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] (1) This application adopts the method of adding a large-area wind-fixing plate with air holes below the V-shaped hook, which can effectively suppress the device's yaw and misorientation caused by the wind force when the blades are retracted below the drone and the wind force at high altitude. It also has the function of balancing the center of gravity of the device without affecting the use of the device.

[0013] (2) The present application cleverly utilizes a rope adaptive adjustment mechanism to suppress the imbalance caused by the height inconsistency of the device when it is hung. Flexible double rope hooks and movable locks are configured at both ends of the flexible traction rope, which can flexibly adjust the length and tightness of the hook. The overall structure is light and lightweight, making it easy to store. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0020] Example:

[0021] See also Figure 1-3 , the utility model provides a technical solution:

[0022] The auxiliary hanging and dismantling device of a drone with high-altitude operation orientation and anti-sway function includes a drone 1 and a flexible traction rope 2. A symmetrical fixing rod 3 is fixedly provided on the lower side wall of the drone 1. The upper ends of the two flexible traction ropes 2 are provided with movable locks 4. The upper ends of the flexible traction ropes 2 are fixed to the outside of the fixing rod 3 through the movable locks 4. The outsides of the lower ends of the two flexible traction ropes 2 are provided with hanging and dismantling rings 5. The lower ends of the hanging and dismantling rings 5 ​​are fixedly provided with hooks 6. The lower ends of the hooks 6 are fixed with wind-fixing wing plates 7. The wind-fixing wing plates 7 have a large area and an opening in the middle, which is convenient for the hook to be hung without interference. At the same time, the influence of wind force when the drone takes off and at high altitude is reduced, and the sway caused by the drone is suppressed. A large-area thin plate is arranged under the hook, which not only increases the weight of the hook device and prevents sway at the same time, but also balances the influence of air vortex generated by wind force in two directions on the hook. It has the functions of wind-fixing, anti-sway and adaptive attitude adjustment.

[0023] The flexible double-rope structure used in this application can greatly reduce the deflection of the device, making it easy to quickly install on the drone frame. It has strong adaptability and is easy to assemble and disassemble. It can be installed on a variety of models and different types of structures. At the same time, it also has the ability to quickly adjust the installation length, and the rope length can be adjusted to meet the needs of the operation.

[0024] By setting the hanging and dismantling device into a V-shaped equal-width structure, the adaptability of hanging and dismantling is increased, which greatly reduces the accuracy and difficulty of hanging and dismantling operations;

[0025] By passing the flexible double ropes through the V-shaped bracket, the V-shaped bracket can adaptively maintain its balance posture through its own weight. Even if any of the double ropes are installed at different heights, the hanging and dismantling device can always maintain a balanced posture.

[0026] A fixed wind wing is set under the V-shaped bracket to balance and reduce the large shaking and deflection of the hanging and dismantling device during high-altitude operation, which greatly improves the hanging and dismantling accuracy and efficiency of the hanging and dismantling operation.

[0027] like Figure 3 In the process, a wire hanging pulley is hung inside the air guide hole 8, and the high-altitude wire is clamped inside the wire hanging pulley.

[0028] The hook 6 is V-shaped and is used for hanging objects.

[0029] The side wall of the wind-fixing vane 7 is provided with an air guide hole 8. The air guide hole 8 on the wind-fixing vane 7 can form convection on the wind-fixing vane 7, so that the wind-fixing vane 7 always maintains a good working posture, thereby suppressing the swinging and shaking of the hanging and disassembling device during high-altitude operation.

[0030] The two flexible traction ropes 2 are slidably connected to the inside of the two hanging and detaching rings 5. In order to achieve the effect of automatic balancing, a rope adaptive adjustment mechanism is set inside the hanging and detaching ring 5. The ropes are hung under the drone frame, and the balance of the hanging and detaching device can be automatically adjusted through this mechanism.

[0031] Working principle:

[0032] The drone drives the device to rise above the ground wire, operates the drone to place the guide arm on the ground wire, and slowly lowers the drone under the guidance of the guide arm so that the ground wire follows the guide arm into the main body. The drone drives the device to rise, and the locking anti-fall device automatically opens. At the same time, the torsion spring is compressed, and the ball spring plunger is positioned to the ball spring plunger positioning hole. At this time, the device is in the open state.

[0033] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
