Description

Technical Field

[0001] This utility model belongs to the field of line de-icing technology, specifically relating to a de-icing device for high-voltage transmission lines. Background Technology

[0002] In recent years, the use of line de-icing devices combined with drones has been gradually rolled out, improving inspection efficiency and reducing safety hazards to some extent. Using drones for de-icing operations reduces the need for high-risk operations such as manually climbing poles, effectively lowering safety risks for workers and ensuring the safety of power operation and maintenance. However, in practical applications, these drone-integrated line de-icing devices still reveal many problems that urgently need to be addressed. In terms of de-icing effectiveness, limited by the device's design and operating principle, it is difficult to efficiently and thoroughly remove ice of complex shapes and varying thicknesses, leaving some areas with residual ice that poses a potential threat to the safe operation of the power lines.

[0003] Patent 202411318024.1 describes an overhead transmission line de-icing robot and its control method, including a housing, a walking mechanism, a clamping mechanism that works with the walking mechanism to clamp the conductors or ground wires of the overhead transmission line, an ice blade mechanism fixed to the housing for removing ice, and a de-icing brush for removing ice from the conductors or ground wires of the overhead transmission line. In practical applications, when the robot described in the prior art lands on an area of ​​transmission lines covered with icicles, the wheels of its walking mechanism first come into contact with the surface of the icicles, preventing effective contact with the surface of the transmission lines. As a result, the icicles cause the wheels to slip. If the cross-section of the ice is too large, the robot may not be able to clamp into the wire, seriously interfering with the normal movement of the device on the transmission line. This makes it difficult to carry out subsequent de-icing tasks smoothly, and may even directly prevent the de-icing operation from being completed, thus significantly hindering the overall progress of the transmission line de-icing work. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a de-icing device for high-voltage transmission lines, which has the advantage of being easy to de-ic.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a de-icing device for high-voltage transmission lines, comprising a drone lifting device, a de-icing frame suspended at the bottom of the drone lifting device, a hook fixedly connected to one outer wall of the de-icing frame, a pushing device rotatably connected to the outer wall of the de-icing frame, a de-icing arm rotatably connected to the transmission end of the pushing device passing through the outer wall of the de-icing frame, an ice-pressing wheel rotatably connected to the outer wall of the ice-pressing arm, de-icing spikes fixedly connected to both outer walls of the ice-pressing wheel, a handle fixedly connected to the outer wall of the de-icing frame, a blade fixing seat fixedly connected to the middle of the outer wall of the de-icing frame, and an adjustable de-icing blade provided on the outer wall of the blade fixing seat.

[0006] The above technical solution facilitates de-icing. The drone lifting equipment hoists the de-icing frame and flies it towards the high-voltage power lines. Because the hook is located on one side of the de-icing frame, the center of gravity shifts to the other side of the hook. This causes the de-icing frame to naturally tilt at a certain angle due to the center of gravity, allowing the power lines to slide more accurately into the channel and precisely into the wheels inside the de-icing device. This significantly reduces the difficulty of mounting the frame and the degree of manual intervention. Once the de-icing frame is successfully lowered, it automatically returns to its normal position under its own weight, restoring a stable operating posture and ensuring the safety and accuracy of the de-icing operation. If there is ice on the cable where the de-icing frame lands, the de-icing arm can be moved up and down to clamp the iced cable by pushing the device. This allows the ice-pressing wheel and de-icing spikes to break the ice, so that the traveling wheels can land on the surface of the cable and avoid slipping on the ice and becoming unable to move. When the de-icing frame moves, the de-icing blade can remove the ice along its path when it encounters ice. If there is any ice that cannot be removed, the de-icing arm can be moved up and down to clamp the iced cable by pushing the device. This allows the ice-pressing wheel and de-icing spikes to break the ice.

[0007] Preferably, the pushing device includes a base fixed to the outer wall of the de-icing rack, an electric push rod rotatably connected to the outer wall of the base, and a rotating arm rotatably connected to the sliding end of the electric push rod, the rotating arm being rotatably connected to the de-icing arm.

[0008] The above technical solution can achieve the driving effect. The device is driven by a linkage mechanism composed of an electric push rod and a rotating arm, which can play a transmission role. The electric push rod pushes the rotating arm to rotate, so that the other end of the rotating arm can drive the de-icing arm to rotate, thereby playing a driving role.

[0009] Preferably, the de-icing knife includes supports of different sizes, and the outer wall of the support and the outer wall of the knife fixing seat have multiple openings that can be aligned with each other. Multiple large knives distributed in a circle are fixedly connected to the outer wall of the support, and multiple small knives inserted between the large knives are fixedly connected to the outer wall of the support.

[0010] The above technical solution can adapt to different cables. Two special de-icing blades are designed to meet the de-icing needs of transmission lines with different wire diameters. The height of the de-icing blade can be steplessly adjusted by flexibly matching the holes on the support and the mounting holes on the blade holder. This allows the de-icing blade to easily adapt to transmission lines with various wire diameters, achieving "one machine for multiple uses" and effectively reducing the equipment procurement and maintenance costs for de-icing operations on transmission lines with different wire diameters.

[0011] Preferably, a guide strip is fixedly connected to one side of the outer wall of the de-icing rack, and a control box is fixedly connected to the outer wall of the guide strip.

[0012] The above technical solution can achieve the effect of control. The control box is used to install the electrical equipment of the device, thereby enabling the control of the de-icing robot.

[0013] Preferably, a first camera is fixedly connected to the outer wall of the guide strip, a second camera is fixedly connected to the outer wall of the tail of the de-icing rack, a third camera is fixedly connected to the outer wall of the front of the de-icing rack, and a fourth camera is fixedly connected to the outer wall of the middle part of the de-icing rack located below the ice pressing wheel.

[0014] The above technical solution can achieve the effect of monitoring. Four cameras can monitor the operation status of the de-icing rack, thereby ensuring that the equipment remains stable during operation.

[0015] Preferably, an electric motor is fixedly connected to the outer wall of the de-icing rack, a gearbox is fixedly connected to the output end of the electric motor, a moving mechanism is driven to the transmission end of the gearbox, the moving mechanism consists of a walking wheel and a transmission belt, and the moving mechanism has two walking wheels connected by the transmission belt, and a battery box is fixedly connected to the outer wall of the de-icing rack.

[0016] The above technical solution can achieve the effect of walking. The electric motor can drive the walking wheels to rotate, so that the walking wheels can walk along the cable, thereby enabling the equipment to work.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. A drone lifting device lifts the de-icing frame and flies it towards the high-voltage power line. Because the hook is located on one side of the de-icing frame, the center of gravity is biased towards the other side of the hook. This causes the de-icing frame to naturally tilt at a certain angle due to the center of gravity, allowing the power line to slide more accurately into the channel and precisely into the wheels inside the de-icing device. This significantly reduces the difficulty of lifting the frame and the degree of manual intervention. After the de-icing frame is successfully lowered onto the power line, it automatically returns to its normal position under its own weight, restoring a stable operating posture and ensuring the safety and accuracy of the de-icing operation. If there is ice at the landing point, the de-icing arm can be controlled to clamp the icy cable by pushing the device. This allows the ice-pressing wheel and de-icing spikes to break the ice, so that the traveling wheels can land on the surface of the cable, preventing the traveling wheels from slipping on the ice and becoming unable to move. When the de-icing frame moves, if it encounters icy areas, the de-icing blade can clear the ice along the way. If there is any ice that cannot be cleared, the de-icing arm can be controlled to clamp the icy cable by pushing the device. This allows the ice-pressing wheel and de-icing spikes to break the ice.

[0019] 2. The device is driven by a linkage mechanism consisting of an electric push rod and a rotating arm. The electric push rod drives the rotating arm, causing it to rotate. This, in turn, drives the de-icing arm. Two specialized de-icing blades are designed to meet the de-icing needs of transmission lines with different diameters. The blade height is infinitely adjustable by flexibly matching the holes on the support with the mounting holes on the blade holder. This allows the de-icing blades to easily adapt to various transmission line diameters, achieving "one machine for multiple uses" and effectively reducing the equipment procurement and maintenance costs for de-icing operations on transmission lines with different diameters.

[0029] 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.

[0030] Example 1:

[0031] Please see Figures 1-8 This utility model provides a technical solution: a de-icing device for high-voltage transmission lines, including a drone lifting device 1, a de-icing frame 2 suspended at the bottom of the drone lifting device 1, a hook 3 fixedly connected to one side of the outer wall of the de-icing frame 2, a pushing device 4 rotatably connected to the outer wall of the de-icing frame 2, a de-icing arm 5 rotatably connected to the transmission end of the pushing device 4 through the outer wall of the de-icing frame 2, an ice-pressing wheel 6 rotatably connected to the outer wall of the ice-pressing arm 5, de-icing spikes 7 fixedly connected to both sides of the outer wall of the ice-pressing wheel 6, a handle 8 fixedly connected to the outer wall of the de-icing frame 2, a blade fixing seat 21 fixedly connected to the middle of the outer wall of the de-icing frame 2, and an adjustable de-icing blade 9 provided on the outer wall of the blade fixing seat 21.

[0032] In this implementation plan, the drone lifting device 1 lifts the de-icing frame 2 and flies it towards the high-voltage power line. Since the hook 3 is located on one side of the de-icing frame 2, the center of gravity is biased towards the other side of the hook 3. This causes the de-icing frame 2 to naturally tilt at a certain angle due to the center of gravity, allowing the power line to slide more accurately into the channel and precisely enter the wheels 17 inside the de-icing device. This significantly reduces the difficulty of lifting the frame and the degree of manual intervention. After the de-icing frame 2 successfully lands on the power line, it automatically returns to its normal position under its own weight, restoring a stable operating posture and ensuring the safety and accuracy of the de-icing operation. If there is ice at the landing point, the ice removal arm 5 can be controlled to clamp the iced cable up and down by pushing the device 4. In this way, the ice pressing wheel 6 and the ice removal spikes 7 can break the ice, so that the traveling wheel 17 can land on the surface of the wire, preventing the traveling wheel 17 from slipping on the ice and becoming unable to move. When the ice removal frame 2 moves, if it encounters an icy location, the ice removal blade 9 can clear the ice along the way. If there is any ice that cannot be cleared, the ice removal arm 5 can be controlled to clamp the iced cable up and down by pushing the device 4. In this way, the ice pressing wheel 6 can break the ice, and the ice removal spikes 7 can also break the ice.

[0033] Example 2:

An electric push rod 401 is rotatably connected to the outer wall of the base 400. A rotating arm 402 is rotatably connected to the sliding end of the electric push rod 401. The rotating arm 402 is used to rotatably connect with the de-icing arm 5. The de-icing blade 9 includes supports 900 of different sizes. Multiple openings that can be aligned with each other are opened on the outer wall of the support 900 and the outer wall of the blade fixing seat 21. Multiple large blades 901 distributed in a circle are fixedly connected to the outer wall of the support 900. Multiple small blades 902 inserted between the large blades 901 are fixedly connected to the outer wall of the support 900.

[0035] In this embodiment, the driving device 4, through the linkage mechanism composed of the electric push rod 401 and the rotating arm 402, can play a transmission role. By pushing the rotating arm 402 with the electric push rod 401, the rotating arm 402 can be rotated, so that the other end of the rotating arm 402 can drive the de-icing arm 5 to rotate, thereby playing a driving role. In order to meet the de-icing needs of transmission lines with different wire diameters, two special de-icing blades 9 are designed. Through the flexible cooperation between the holes on the support 900 and the mounting holes on the blade fixing seat 21, the height of the de-icing blade 9 can be steplessly adjusted, so that the de-icing blade 9 can easily adapt to transmission lines with various wire diameters, realize "one machine for multiple uses", and effectively reduce the equipment procurement and maintenance costs of de-icing operations for transmission lines with different wire diameters.

[0036] Example 3:

[0037] Please see Figures 1-8 Based on Embodiments 1 and 2, this utility model provides a technical solution: a guide strip 10 is fixedly connected to one side of the outer wall of the ice remover 2, a control box 11 is fixedly connected to the outer wall of the guide strip 10, a first camera 12 is fixedly connected to the outer wall of the guide strip 10, a second camera 13 is fixedly connected to the outer wall of the tail of the ice remover 2, a third camera 14 is fixedly connected to the outer wall of the front of the ice remover 2, a fourth camera 20 is fixedly connected to the outer wall of the middle part of the ice remover 2 and located below the ice pressing wheel 6, a motor 15 is fixedly connected to the outer wall of the ice remover 2, a gearbox 16 is fixedly connected to the output end of the motor 15, a moving mechanism is driven to the transmission end of the gearbox 16, the moving mechanism consists of two walking wheels 17 and a transmission belt 18, and the moving mechanism has two walking wheels 17 connected by the transmission belt 18, and a battery box 19 is fixedly connected to the outer wall of the ice remover 2.

[0038] In this embodiment, the control box 11 is used to install the electrical equipment of the device, thereby controlling the de-icing robot. The operation status of the de-icing rack 2 can be monitored by four cameras to ensure that the device remains stable during operation. The motor 15 can drive the walking wheels 17 to rotate, so that the walking wheels 17 can walk along the cable, thereby enabling the device to work.

[0039] The working principle and usage process of this utility model are as follows: The drone lifting device 1 lifts the de-icing frame 2 and flies it towards the high-voltage power line. Since the hook 3 is located on one side of the de-icing frame 2, the center of gravity is biased towards the other side of the hook 3. This causes the de-icing frame 2 to naturally tilt at a certain angle due to the center of gravity, allowing the power line to slide more accurately into the channel and precisely enter the traveling wheels 17 inside the de-icing device. This significantly reduces the difficulty of lifting the frame and the degree of manual intervention. After the de-icing frame 2 successfully lands on the power line, it automatically returns to its original position under its own weight, restoring a stable operating posture and ensuring the safety and precision of the de-icing operation. For accurate positioning, if ice forms at the point where the de-icing frame 2 touches the power line, the de-icing arm 5 can be controlled up and down by pushing device 4 to clamp the iced cable. This allows the ice-pressing wheel 6 and de-icing spikes 7 to break the ice, ensuring the traveling wheel 17 can rest on the surface of the power line and avoid slipping on the ice. When the de-icing frame 2 moves, the de-icing blade 9 can remove ice along its path. If any ice remains, pushing device 4 can control the de-icing arm 5 to clamp the iced cable, allowing the ice-pressing wheel 6 to break the ice. Ice is broken, and the ice-removing spikes 7 can also break up the ice. The driving device 4, through the linkage mechanism composed of the electric push rod 401 and the rotating arm 402, can play a transmission role. The electric push rod 401 pushes the rotating arm 402, which can rotate. In this way, the other end of the rotating arm 402 can drive the ice-removing arm 5 to rotate, thus playing a driving role. For the ice removal needs of transmission lines with different wire diameters, two special ice-removing blades 9 are designed. They are flexibly matched with the holes on the support 900 and the mounting holes on the blade fixing seat 21 to achieve high-speed operation of the ice-removing blades 9. The stepless adjustment of the degree allows the de-icing blade 9 to easily adapt to power transmission lines of various diameters, achieving "one machine for multiple uses" and effectively reducing the equipment procurement and maintenance costs for de-icing operations on power transmission lines of different diameters. The control box 11 is used to install the electrical equipment of the equipment, thereby controlling the de-icing robot. Four cameras can monitor the operating status of the de-icing frame 2, thereby ensuring that the equipment remains stable during operation. The motor 15 can drive the walking wheels 17 to rotate, so that the walking wheels 17 can walk along the cable, allowing the equipment to work.
