Description

Technical Field

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

[0002] In the field of drone-borne de-icing technology, existing devices on the market still have many technical shortcomings, making it difficult to meet the needs of efficient, safe, and flexible de-icing operations in complex icy and snowy environments. Specifically:

[0003] Existing devices generally suffer from problems such as limited functionality or unreasonable functional integration:

[0004] On the one hand, most single-function hanging devices can only be equipped with one of the knocking rod de-icing device or the vibration de-icing device, and cannot flexibly switch the de-icing method according to different ice thicknesses and cable types, resulting in limited de-icing effect. For example, when facing a thick ice layer, knocking or vibration alone is not enough to completely remove the ice and snow, resulting in low work efficiency.

[0005] On the other hand, although a few hybrid-function sling devices attempt to integrate multiple de-icing functions, their redundant structural design and excessive weight place extremely high demands on the drone's load capacity, which not only increases the cost of selecting drones but also limits their adaptability to small drones.

[0006] Some of the striking rods have a metal surface design and are not insulated or the insulation method does not meet industry standards. When they come into contact with high-voltage transmission lines for de-icing operations, they are very likely to cause arcing and threaten the safe operation of the power system. At the same time, the metal striking rods make "hard-to-hard" contact with the cables, which will cause wear and tear on the cable surface over a long period of time, shorten the cable's service life and increase the cost of power maintenance.

[0007] When hoisting ropes or de-icing equipment accidentally become entangled or jammed during operations, the equipment lacks automatic identification and emergency throwing functions, requiring ground personnel to visually assess the anomaly. However, drones operate at high altitudes, and ground personnel are far from the drone, making it difficult to quickly and accurately identify entanglement or jamming with the naked eye. Furthermore, manual intervention to release the entanglement after assessment is slow, often missing the optimal release opportunity. If the jammed rope suddenly pulls on the drone, it can easily lose balance, causing a crash and resulting in damage to the drone equipment and interruption of operations. Utility Model Content

[0008] The purpose of this invention is to provide a drone-mounted de-icing device, which solves the aforementioned problems when used in operation.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a drone hoisting de-icing device, comprising a drone body, an angle delivery component and a hoisting lug component, wherein the angle delivery component is installed at the bottom of the drone body, the hoisting lug component is provided at the bottom of the angle delivery component, the hoisting lug component is provided at the bottom of the hoisting lug component, and the de-icing component is provided at the bottom of the hoisting rope.

[0010] The de-icing assembly includes a striking assembly and a vibrating fork assembly. The striking assembly includes an externally threaded steel pipe, a plastic pipe, an internally threaded pipe cap, external and internal angle bolts, and a second lifting ring. The vibrating fork assembly includes a housing, a third lifting ring, a vibrating motor, a vibration damping seat, a battery, a vibration damping support, a control module, a U-shaped vibrating fork assembly, a counterweight plate, and a U-shaped fork.

[0011] Preferably, the angle delivery component includes a housing, a mounting bracket, a launcher body, grippers, and sensors. The housing is located at the bottom of the UAV body, the mounting bracket is fixed on both sides of the top of the housing, the launcher body is installed on the inner top wall of the housing, grippers are provided at the bottom of the launcher body, and sensors are installed on both sides of the bottom of the housing.

[0012] Preferably, the lifting lug assembly includes a lifting lug frame, a lifting ring, a swing lug, a safety buckle, and tension springs. The lifting lug frame is located on the top of the housing. A lifting ring is installed on the top of the lifting lug frame. The lifting ring extends from the bottom of the housing and is connected to the gripper. A swing lug is located at the middle of the bottom of the lifting lug frame. A safety buckle is located at the bottom of the swing lug. The swing lug and the safety buckle are welded together. Tension springs are located on both sides of the safety buckle. One end of each tension spring is connected to one side of the bottom of the lifting lug frame.

[0013] Preferably, the bottom of the safety buckle one is provided with a suspension rope, and the bottom of the suspension rope is provided with a safety buckle two, which can be used to suspend the striking component and the vibrating fork component.

[0014] Preferably, a plastic tube is provided on the outside of the externally threaded steel pipe, an internally threaded cap is provided at the bottom of the plastic tube, an external and internal angle bolt is provided at the top of the internally threaded cap, and a second lifting ring is fixed at the top of the external and internal angle bolt, which can be hung on the second safety buckle.

[0015] Preferably, a vibration motor is installed inside the outer casing, a vibration damping seat is installed on top of the vibration motor, a battery is installed on top of the vibration damping seat, a control module is installed at the bottom of the vibration damping seat, vibration damping supports are installed at the four corners of the bottom of the vibration damping seat, a U-shaped vibration fork assembly is installed at the bottom of the outer casing, counterweight plates are installed on both sides of the bottom of the U-shaped vibration fork assembly, a U-shaped fork is installed at the bottom of the counterweight plates, a power transmission cable is installed in the middle of the bottom of the U-shaped vibration fork assembly, and a lifting ring three is installed in the middle of the top of the outer casing, which can be hung on the safety buckle two.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The drone hoisting de-icing device provided by this utility model, through sensors installed on both sides of the bottom of the casing and built-in through-beam light sources, can sensitively detect abnormal swinging of the hoisting rope, striking component, or vibrating fork component. Once the hoisting lug component swings too much due to accidental entanglement or jamming, the sensor will immediately identify the abnormality, quickly control the opening of the gripper of the angle delivery component, and decisively throw the hoisting lug component, effectively preventing the drone from crashing and building a solid defense for the safe operation of the drone;

[0018] The combination of the swing arm and the tension spring further optimizes the stability and reliability of the device. When the suspension rope swings slightly, the tension spring can absorb the impact force in time, preventing the components from shaking violently due to minor obstacles and effectively avoiding false triggering of the sensors. This design ensures that in complex field environments, the device can remain "immune" to minor disturbances, maintaining the continuity and efficiency of de-icing operations, while also quickly activating the separation protection mechanism when encountering major risks that endanger the safety of the drone, such as severe jamming. This achieves the ideal effect of "no interruption for minor disturbances and rapid protection for major risks," greatly improving the system's adaptability and reliability in complex environments.

[0019] 2. The drone-mounted de-icing device provided by this utility model uses a rod-type de-icing device equipped with a striking component. Utilizing its HDPE insulated plastic tube, which has a lower hardness than the cable, it cleverly balances de-icing effectiveness and cable protection during the striking de-icing process. It can efficiently de-ic both power transmission towers and power lines simultaneously. The vibration de-icing device is equipped with a vibration fork assembly. The high-frequency vibration generated by the vibration motor quickly shakes off the ice layer on the cable surface. Vibration-damping supports improve the stability and service life of the device, while the counterweight plate and U-shaped fork design optimize operational convenience and efficiency. It is specifically designed for vibration de-icing of power transmission lines.

[0020] The two de-icing devices can operate independently to address different icing scenarios, or they can be used together to synergistically improve de-icing efficiency, significantly enhancing the de-icing effect compared to a single de-icing method. Furthermore, the ability to flexibly attach the appropriate device according to actual de-icing needs effectively avoids placing unnecessary loads on the drone, greatly improving energy efficiency. The lightweight de-icing devices reduce the load requirements on the drone, extending flight time and improving flight safety with the same drone configuration. This dual de-icing design not only excels in de-icing overhead power lines but can also be extended to various scenarios susceptible to ice and snow disasters, such as agriculture, forestry, road transportation, and bridge facilities, providing an efficient and reliable technical solution for addressing ice and snow hazards in different fields.

[0041] Specifically, this drone-mounted de-icing system features a modular design, with its core equipped with a striking component 5 and a vibrating fork component 6. These components can operate independently or in combination to synergistically improve de-icing efficiency. The overall functional advantages of the system are as follows:

[0042] The rod-type de-icing device, equipped with the striking component 5, can simultaneously knock out ice from both the transmission tower and the transmission line; the vibration de-icing device, equipped with the vibration fork component 6, can specifically de-ic the transmission line by vibration, meeting the needs of different icing scenarios.

[0043] It supports flexible attachment of corresponding devices according to actual de-icing needs, avoiding unnecessary load on the drone and significantly improving energy efficiency; at the same time, the de-icing device itself is lightweight, reducing the load requirements on the drone, and can extend the flight time and improve flight safety with the same drone configuration.

[0044] The lightweight design makes the device easier to transport to areas near overhead lines, making it especially suitable for tower operations far from highways, thus overcoming geographical limitations.

[0045] 1. Rod-type de-icing

[0046] The plastic tube 52 in the component is made of HDPE insulating plastic, which has a lower hardness than the cable material. This can prevent damage to the cable during the knocking de-icing process, thus balancing the de-icing effect and equipment protection.

[0047] By connecting the second 55 of the component 5 to the second 41 of the rope 4, the component is suspended at the bottom of the drone; the drone then moves the component to the target power transmission tower and performs de-icing operation by mechanically striking it.

[0048] II. Vibration De-icing

[0049] The vibration motor 63 generates high-frequency vibrations, which can quickly shake off the ice layer on the cable surface.

[0050] The vibration damping support 66 can significantly reduce the vibration amplitude of internal components, improve device stability and extend service life. This structure is also provided at the four corners of the bottom of the vibration damping seat 64 to provide vibration damping protection for the control module 67 and the battery 65.

[0051] The counterweight plate 69 keeps the component's center of gravity below the cable, preventing it from tipping over during operation; the U-shaped fork 610 design facilitates quick attachment of the component to the cable, improving work efficiency.

[0052] The vibratory fork assembly 6 is suspended from the bottom of the drone by connecting the lifting ring 3 62 of the vibratory fork assembly 6 to the safety buckle 2 41 of the lifting rope 4; the drone is controlled to lower the U-shaped vibratory fork assembly 68 from the top of the power transmission cable 7 until the U-shaped part clamps the cable, as shown. Figure 10 As shown; the vibration motor 63 is started by the ground remote control, and the vibration causes the ice and snow on the cable to break and fall off.

[0053] 3. Sensors 25 are located on both sides of the bottom of the housing 21. When the lifting lug assembly 3 is installed at the bottom of the angle delivery assembly 2, the detection slots of the sensors 25 are embedded on both sides of the lifting lug 31. The sensors 25 have built-in through-beam light sources. During normal operation, the gripper 24 remains connected to the lifting ring 32. If the lifting rope 4, the striking assembly 5, or the vibration fork assembly 6 accidentally becomes entangled or jammed, causing the lifting rope 4 to swing excessively, the lifting lug 31 will swing and block the through-beam light source between the sensors 25. At this time, the sensors 25 can automatically and quickly identify the abnormality, control the gripper 24 to open and disconnect from the lifting ring 32, and complete the throwing of the lifting lug assembly 3 and the lifting rope 4, effectively preventing the drone from crashing and ensuring the safety of the drone.

[0054] The top of the swing lug 33 is connected to the lug frame 31 by a rotating bearing, allowing the swing lug 33 and safety buckle 34 to swing flexibly at the bottom of the lug frame 31; at the same time, tension springs 35 are set on both sides of the safety buckle 34, the core function of which is:

[0055] When the suspension rope 4 swings slightly, the tension spring 35 can absorb the impact of the swing, preventing the component from shaking violently due to minor obstacles.

[0056] To prevent the sensor 25 from being directly triggered by small-amplitude swings, the sensor 25 is only triggered to control the connection separation when a large obstacle causes the lug assembly 3 to swing beyond the safety threshold.

[0057] The purpose of this design is to improve the system's operational stability and fault tolerance while ensuring the safety of the drone. Through the buffering effect of the tension spring 35 and the swing threshold control, frequent shutdowns and operational interruptions caused by minor disturbances are avoided, ensuring the continuity and efficiency of de-icing operations. Furthermore, in situations where serious jamming or entanglement threatens the drone's safety, the separation protection mechanism can be activated promptly, achieving the dual goals of "no interruption due to minor disturbances and rapid protection against severe risks." This balances operational efficiency and equipment safety, giving the system greater adaptability and reliability in complex field de-icing environments.

[0058] The application of this drone-mounted de-icing system is not limited to overhead power lines; it can also cover multiple scenarios susceptible to ice and snow disasters, effectively solving ice and snow hazards in different fields.

[0059] In the agricultural and forestry sectors: Winter snow and freezing rain can easily cause small trees to fall, affecting their normal growth and increasing the workload for farmers to prop up fallen saplings. For large trees, the weight of snow and freezing rain can cause the treetops to break, directly impacting their growth and appearance, thus reducing farmers' income. This system, with its modular design, allows for the attachment of either a hammering component 5 or a vibrating fork component 6, depending on the tree size and icing conditions. A drone-borne device can then precisely remove snow and ice from the trees, minimizing damage to forests.

[0060] In the field of road traffic: Bamboo or trees along the roadside are prone to falling onto the road surface during snow and freezing rain, creating road obstructions, affecting vehicle traffic efficiency, and even causing traffic accidents. This system can quickly respond to such hazards by using drones to remove ice and snow from roadside bamboo and trees, eliminating the risk of falling trees in advance, and ensuring smooth road traffic and driving safety.

[0061] In the field of bridge infrastructure: When suspension bridge cables freeze, the weight of the ice increases the load on the cables, and long-term accumulation may damage the cable structure, even leading to the risk of bridge collapse in extreme cases. This system can select appropriate de-icing components based on the characteristics of icing on suspension bridge cables, reducing damage to the cables from the ice and ensuring the safety of the bridge structure.

[0062] To further improve operational efficiency and response speed, drone airports can be set up near road sections, forest areas, or bridges prone to snow and ice disasters. During snowfall, drones can be dispatched from the airports to conduct regular patrols of the relevant areas, simultaneously capturing image data and transmitting it back to the backend system. The system then analyzes the snow and ice accumulation and the timing of de-icing. Once the de-icing threshold is reached, drones carrying corresponding de-icing equipment can be immediately dispatched to perform snow and ice removal operations on targets such as bamboo, trees, roadside vegetation, or bridge cables, achieving early prevention and rapid response to snow and ice disasters.
