Description

Technical Field

[0001] This utility model relates to the field of drone de-icing equipment, and in particular to a drone de-icing device for overhead power transmission lines. Background Technology

[0002] In modern power transmission systems, transmission lines serve as crucial channels for energy delivery. Their safe and stable operation directly impacts the reliability of the entire power grid and the normal functioning of the socio-economic system. However, under harsh climatic conditions such as high altitude, low temperature, and high humidity, transmission lines are highly susceptible to icing. Icing significantly increases the weight of the lines, leading to tower tilting and collapse, and even serious accidents such as conductor breakage and insulator string fracture, posing a significant threat to the safe and stable operation of the power system.

[0003] In recent years, drones have been widely used in the field of power transmission line inspection due to their advantages such as high mobility, flexible operation, and ability to perform high-altitude operations. Common drone-based de-icing equipment for power transmission line conductors uses laser removal technology. When transporting and maintaining drones, it is usually necessary to remove the laser equipment from the drone. However, existing methods often use multiple sets of bolts for installation. During disassembly and maintenance, workers need to carry tools and work in the field, which can delay the best processing time, especially in emergency repair scenarios. Therefore, a drone-based de-icing device for overhead power transmission lines is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a drone de-icing device for overhead power transmission lines, which aims to improve the problems in the existing technology that "traditional devices rely on multiple sets of bolts to fix laser equipment, require tools to be carried for field maintenance, and are prone to delaying operation time during emergency repairs".

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an overhead power transmission line drone de-icing device, comprising a drone body, a connecting component at the lower part of the drone body, a laser device at the lower part of the connecting component, and a protective component at the upper part of the drone body; the connecting component includes a connector fixedly connected to the lower part of the drone body, an mounting cylinder on the outer side of the connector, the mounting cylinder fixedly connected to the upper part of the laser device, a rotating ring slidably connected to the inner wall of the mounting cylinder, protrusions on the outer sides of both the mounting cylinder and the rotating ring, a sliding groove on the outer side of the connector, the protrusions on the outer side of the rotating ring inserting into the inner wall of the sliding groove, an operating block fixedly connected to the outer side of the rotating ring, and a shell fixedly connected to the outer side of the mounting cylinder, the operating block being elastically connected to the shell via a spring.

[0006] As a further description of the above technical solution:

[0007] The mounting cylinder has a movable groove on its outer side, and the rotating ring slides on the inner wall of the movable groove.

[0031] 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.

[0032] Reference Figures 1-3This utility model provides an embodiment of an overhead power transmission line unmanned aerial vehicle (UAV) de-icing device, comprising a UAV body 1, which serves as the platform for the entire device, providing the power, control, and stability required for flight, and simultaneously supporting a connecting component 2, a laser device 3, and a protective component 4. The connecting component 2 is located at the lower part of the UAV body 1, and the laser device 3, consisting of a battery pack, a gimbal, and a laser emitter, is located below the connecting component 2. This laser device is used to remove ice from the power transmission line conductors using emitted laser light. This technology is prior art and will not be described in detail. A protective component 4 is located at the upper part of the UAV body 1. Component 4; The connecting component 2 includes a connector 27 fixedly connected to the lower part of the UAV body 1, which serves as the core support structure of the connecting component 2 and is used to support the mounting cylinder 21 and the rotating ring 23. The mounting cylinder 21 is provided on the outside of the connector 27 for mounting the connector 27, which facilitates the quick installation or removal of the laser device 3. The mounting cylinder 21 is fixedly connected to the upper part of the laser device 3. The rotating ring 23 is slidably connected to the inner wall of the mounting cylinder 21. By rotating the rotating ring 23, the connector 27 can be locked. A moving groove is provided on the outside of the mounting cylinder 21, and the rotating ring 23 slides on the inner wall of the moving groove.

[0033] Reference Figure 2 , Figure 3 and Figure 6 Both the mounting cylinder 21 and the rotating ring 23 have protrusions 22 on their outer sides. The connector 27 has a groove 28 on its outer side. The protrusions 22 on the outer side of the rotating ring 23 are inserted into the inner wall of the groove 28 to lock the connector 27. An operating block 24 is fixedly connected to the outer side of the rotating ring 23. An operating groove is opened on the outer side of the operating block 24 to facilitate the operator to rotate the rotating ring 23. A housing 25 is fixedly connected to the outer side of the mounting cylinder 21 for installing a spring 26. The operating block 24 is elastically connected to the housing 25 through the spring 26. The elastic force of the spring 26 makes the protrusions 22 on the outer side of the rotating ring 23 stably inserted into the inner wall of the groove 28 to ensure the stability of the connection. The protrusions 22 on the outer side of the mounting cylinder 21 are inserted into the inner wall of the connector 27 to prevent the laser device 3 from rotating.

[0034] Reference Figures 1-3 The protective component 4 includes a mounting piece a41 that fits onto the outside of the drone body 1. The mounting piece a41 is inserted into the mounting piece b43. The protective cover 42 is quickly installed on the drone body 1. The protective cover 42 is fixedly connected to the outside of the mounting piece a41. The protective cover 42 covers the top of the propeller of the drone body 1, forming a physical barrier to prevent branches, birds, foreign object fragments, etc. from hitting the propeller and avoid flight loss of control such as power imbalance and shutdown due to propeller damage. It is especially suitable for areas with dense vegetation or frequent bird activity. The mounting piece b43 is inserted into the upper part of the mounting piece a41. The inner side of the mounting piece b43 fits onto the outside of the drone body 1.

[0035] Reference Figure 2 , Figure 4 and Figure 5 The lower inner wall of the mounting component a41 is slidably connected to a limiting component 45, which is inserted into the slot 44 of the mounting component b43 to achieve a fixed connection between the mounting component a41 and the mounting component b43. Multiple sets of limiting components 45 are provided, and adjacent sets of limiting components 45 are elastically connected by metal springs 46. The metal springs 46 are set in an arc shape to provide tension so that the limiting components 45 are tightly locked into the slots 44, while allowing a certain degree of deformation to adapt to slight size differences or vibrations of the drone body 1 and enhance the reliability of the connection. The outer side of the mounting component b43 has a slot 44 through it, and the limiting component 45 is inserted into the inner wall of the slot 44. The outer side of the drone body 1 is provided with a groove at an angle. The inner sides of the mounting components a41 and b43 are provided with anti-movement grooves that cooperate with the grooves. By cooperating with the grooves and anti-movement grooves, the protective component 4 can be locked on the outer side of the drone body 1, improving its stability.

[0036] Working principle: During use, the operator manually operates the connecting component 2 to drive the operating block 24 to overcome the tension of the spring 26, pull or push the operating block 24 outward, and drive the rotating ring 23 to rotate along the inner wall of the mounting cylinder 21, so that the protrusion 22 on the outer side of the rotating ring 23 disengages from the initial locking position of the sliding groove 28 of the connecting piece 27, and the laser equipment 3 can be quickly removed for maintenance or transportation.

[0037] Laser device 3 emits a high-energy laser beam, which is focused on the ice on the power transmission line, causing it to heat up rapidly, vaporize, and thus detach from the conductor.

[0038] The protective cover 42 is placed above the propeller blades to form a physical barrier. If debris is generated during the removal of foreign objects, the protective cover 42 can block the debris from hitting the propeller blades, preventing the propeller blades from deforming or becoming unbalanced and causing the drone to lose control. When operating in densely vegetated areas, the protective cover 42 can also prevent branches from scratching the propeller blades, making it especially suitable for power transmission lines that cross forests or complex terrain.

[0039] After the operation is completed, if transportation or maintenance is required, the metal spring 46 can be elastically deformed by the limiting member 45 in the sliding mounting part a41, so that it can be disengaged from the slot 44 of the mounting part b43, and the protective component 4 can be quickly disassembled. After disassembly, the protective cover 42 can be cleaned separately to remove surface dust or foreign matter residue.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
