Description

Technical Field

[0001] This invention relates to the field of power distribution network line maintenance technology, and in particular to a de-icing device for power distribution network line protection. Background Technology

[0002] Icing and snow accumulation on power distribution networks threaten the safe and reliable operation of the power system. Rain, snow, and freezing weather can cause large-scale icing on transmission lines, leading to the collapse and breakage of transmission towers, damage to power facilities, and power outages, causing enormous disasters and losses to people's lives and production, resulting in significant direct economic losses. Besides the rare, widespread, and prolonged low temperatures, rain, snow, and freezing weather, and the insufficient ability of power distribution networks to withstand severe weather, another important reason for icing on power distribution networks is the lack of effective de-icing methods. Currently, de-icing and anti-icing technologies are generally energy-intensive and have low safety performance; there are no safe, effective, and simple methods. In most remote areas, de-icing of many power distribution networks still relies on manual labor to climb high-voltage towers and chip away at the ice along the cables. Because power distribution network installations are often done at heights, this de-icing method is not only inefficient but also extremely dangerous.

[0003] While existing technologies have introduced de-icing devices to address issues arising from manual operation, these devices still suffer from unstable connections with cables. Current de-icing devices typically rely on rollers directly contacting the cables, which doesn't guarantee a secure lock after installation. Furthermore, manual disassembly and recovery are still required after the operation, making the process complex, difficult, and reducing overall work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a de-icing device for the protection of power distribution network lines, which can effectively ensure the stability of the overall equipment and cable connection, and facilitate the installation and disassembly of operators, thereby reducing the labor intensity of operators and improving the overall work efficiency.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0033] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0036] like Figures 1 to 11As shown, a de-icing device for power distribution line protection in this embodiment includes a chassis 100 and a mounting assembly 300 and a de-icing assembly 500 respectively mounted on the chassis 100. The mounting assembly 300 includes a fixing member 310 and a self-locking member 320. The fixing member 310 includes a fixing seat 311 fixedly connected to the chassis 100 and a rotating buckle 312 hinged to the fixing seat 311. The fixing seat 311 and the rotating buckle 312 are engaged to form a wire groove for the cable 700 to pass through. The self-locking member 320 is mounted on the fixing member 310 and includes a claw 321 and a first driving member. The claw 321 is engaged with the rotating buckle 312. The first driving member is driven to engage the claw 321 with the rotating buckle 312 and / or disengage the claw 321 from the rotating buckle 312. The de-icing assembly 500 includes a de-icing rod 520 that reciprocates toward the surface of the cable 700. The reciprocating motion of the de-icing rod 520 is used to beat the ice attached to the surface of the cable 700 to achieve the de-icing effect.

[0037] In this embodiment, the entire chassis 100 is mounted on the cable 700 by the fixing member 310 of the mounting assembly 300, and the ice adhering to the surface of the cable 700 is removed by the de-icing rod 520 that reciprocates toward the surface of the cable 700. The fixing seat 311 and the rotating buckle 312 are hinged together to form a cable groove through which the cable 700 passes. The fixing seat 311 and the rotating buckle 312 also clamp the cable 700, ensuring a firm connection between the fixing member 310 and the cable 700, preventing shaking or detachment, and thus contributing to the stability of the de-icing assembly 500 during operation. Specifically, the self-locking component 320's claw 321 is engaged with the rotating buckle 312 to achieve the engagement and fixation of the rotating buckle 312 and the fixed base 311. Furthermore, the first driving component is connected to the claw 321 for transmission, so that the first driving component controls the engagement and disengagement of the claw 321 and the rotating buckle 312. Thus, the first driving component can be used to conveniently control the fixing, installation, and disassembly of the fixed component 310 and the cable 700, reducing the labor intensity of the operator and improving the efficiency of disassembly and installation.

[0038] In actual operation, it also includes a remote controller (not shown) connected to the first driving component. The first driving component is controlled remotely, thereby enabling the locking and unlocking of the fixed component 310. This facilitates remote operation by the operator, eliminating the need for the operator to perform heavy climbing work, reducing the operator's labor intensity, and improving the safety of the operation.

[0039] In one embodiment, two claws 321 are provided, which are adapted to engage with the two sides of the rotating buckle 312 respectively. The first driving member includes a locking spring 322, the two ends of which are connected to the connecting rods 324 of the two claws 321 respectively, and the locking spring 322 enables the two claws 321 to always tend to move closer to each other. Specifically, the claws 321 are set in the grooves on the fixed base 311. The two claws 321 have a pressing slope 3211 on the opposite side. The end of the rotating buckle 312 connected to the claws 321 has a locking protrusion 3121. When the rotating buckle 312 rotates to abut against the claws 321, the locking protrusion 3121 abuts against the pressing slope 3211 and presses the two claws 321, causing the two claws 321 to move away from each other. The locking slot between the two claws 321 opens. When the locking protrusion 3121 exceeds the pressing slope 3211 and loses the pressing force on the pressing slope 3211, the two claws 321 move closer to each other under the action of the locking spring 322. Thus, the two claws 321 lock the locking protrusion 3121 from both sides of the rotating buckle 312, realizing the fixed connection between the rotating buckle 312 and the fixed base 311. Of course, in other embodiments, other limiting structures or connecting structures can also be used, as long as the controllable locking and unlocking of the rotating buckle 312 and the fixed seat 311 can be achieved. Such designs are all within the protection scope of this invention.

[0040] Furthermore, the first driving component also includes an electromagnet 323, which is respectively disposed on the opposite side of the two connecting rods 324. When it is necessary to detach the fixing component 310 from the cable 700, the electromagnet 323 is energized and the opposite sides of the electromagnets 323 on the two connecting rods 324 are set with the same pole. At this time, according to the principle that like magnetic poles repel each other, the electromagnets 323 on the two connecting rods 324 generate a repulsive magnetic force after being energized, causing the two claws 321 to move away from each other. At this time, the claws 321 release the lock on the rotating buckle 312, releasing the rotating buckle 312 to facilitate the subsequent disassembly and recycling work.

[0041] Furthermore, in actual operation, during the de-icing process, the electromagnet 323 can be energized throughout the entire process, and the electromagnets 323 on the two connecting rods 324 can be arranged with opposite poles on opposite sides. At this time, according to the principle of attraction between opposite magnetic poles, the electromagnets 323 on the two connecting rods 324 will generate a magnetic force after being energized, so that the two claws 321 tend to be relatively close throughout the entire process, so that the two claws 321 can tightly lock the rotating buckle 312, which helps to improve the connection between the claws 321 and the rotating buckle 312.

[0042] In one embodiment, a drive assembly 600 is also included. The drive assembly 600 includes a second drive member 610, which is kinetically connected to the rotating buckle 312 to drive the rotating buckle 312 to rotate relative to the fixed base 311, thereby controlling the locking and unlocking of the rotating buckle 312 and the fixed base 311. In actual operation, the second drive member 610 can be connected to a remote controller to remotely control the locking and unlocking of the fixed component 310, facilitating remote operation by the operator. This eliminates the need for the operator to perform heavy climbing work, reducing the operator's labor intensity and improving operational safety.

[0043] Specifically, the drive assembly 600 also includes a drive gear 620, a transmission gear 630, and a linkage shaft 640. The drive gear 620 is connected to the output shaft of the second drive member 610, and the drive gear 620 meshes with the transmission gear 630. The transmission gear 630 is fixedly connected to the linkage shaft 640, which is connected to the rotating buckle 312. The second drive member 610 drives the drive gear 620 to rotate, which in turn drives the transmission gear 630 to rotate, which in turn drives the linkage shaft 640 to rotate the rotating buckle 312 relative to the fixed seat 311. In actual operation, two sets of fixed members 310 are provided, symmetrically arranged on both sides of the chassis 100 to ensure the stability of the connection. The two sets of rotating buckles 312 are respectively connected to the linkage shaft 640, so that the drive assembly 600 synchronously drives the two sets of rotating buckles 312 to rotate through the linkage shaft 640, thereby achieving the fastening or loosening of the two sets of rotating buckles 312 with the fixed seat 311.

[0044] In one embodiment, a walking assembly 400 is also included. The walking assembly 400 includes a walking drive 410 and a walking wheel 420. The walking drive 410 is mounted on the chassis 100 and is connected to the walking wheel 420 in a transmission manner. The walking wheel 420 abuts against the cable 700 and is connected to the cable 700 by rolling. The walking drive 410 drives the walking wheel 420 to rotate, thereby driving the entire chassis 100 to move on the cable 700.

[0045] In one embodiment, the walking wheel 420 includes a hub 421 and an elastic deformable tire 422. The hub 421 is connected to the walking drive component 410, and the deformable tire 422 is fitted on the outside of the hub 421 and abuts against the cable 700. Specifically, the walking drive component 410 is a servo motor, which is mounted and fixed to the housing 100 via a mounting bracket 411. The output shaft of the servo motor is connected to the hub 421 to drive the hub 421 to rotate. In this embodiment, the servo motor is signal-connected to a remote controller to achieve remote control.

[0046] Furthermore, the deformable tire 422 has a hollow internal structure, and the surface of the deformable tire 422 that contacts the cable 700 is provided with anti-slip textures and raised particles (not shown). This allows it to move smoothly on slippery ice surfaces or when the cable 700 has a large curvature, preventing slippage. The hollow internal structure is inflated to increase the surface elasticity of the deformable tire 422, allowing it to deform according to different ice formations on the cable 700 surface. This better conforms to the surface of the cable 700, increasing the overall stability of the equipment.

[0047] In one embodiment, the walking component 400 further includes an auxiliary wheel 430, which is mounted on the fixed component 310 and is tactilely connected to the cable 700. This reduces friction between the fixed component 310 and the cable 700 during movement, minimizing damage to the cable 700 and ensuring smooth movement of the entire device on the cable 700. In actual operation, the auxiliary wheel 430 is made of elastic rubber to allow it to roll smoothly on the uneven surface of the cable 700, which may be covered with ice. The rubber material also provides cushioning to the cable 700, preventing damage.

[0048] In one embodiment, the chassis 100 has a mounting cavity 120, the bottom of the mounting cavity 120 has a mounting plate 121, the de-icing assembly 500 is mounted on the mounting plate 121, the top of the chassis 100 has a de-icing port 140, and the de-icing assembly 500 extends out of the mounting cavity 120 through the de-icing port 140.

[0049] In this embodiment, the mounting bracket 411 and the walking drive component 410 are also mounted on the mounting plate 121. An opening 111 is provided on the top of the chassis 100 corresponding to the position of the walking wheel 420. The walking wheel 420 extends out of the mounting cavity 120 through the opening 111 and abuts against the cable 700, thereby causing the entire device to move along the cable 700 by rolling on the cable 700. Specifically, a cover plate 110 is provided on the top of the chassis 100, and the opening 111 is provided on the cover plate 110. By opening the cover plate 110, it is convenient to install, disassemble, replace, or maintain the internal components of the chassis 100.

[0050] In one embodiment, a drainage chamber 130 is also provided inside the chassis 100. The drainage chamber 130 is located at the bottom of the mounting cavity 120, and a mounting grille 122 is provided on the mounting plate 121. The drainage chamber 130 and the mounting cavity 120 are connected through the mounting grille 122, and multiple drainage holes 131 are provided at the bottom of the drainage chamber 130. During the de-icing process, ice fragments may fall into the mounting cavity 120 of the chassis 100 through the opening 111. The ice fragments falling into the mounting cavity 120 will melt into water. At this time, the water can flow into the drainage chamber 130 through the mounting grille 122, and then be discharged through the drainage holes 131 at the bottom of the drainage chamber 130. This helps to keep the inside of the chassis 100 dry, prevent the equipment inside the chassis 100 from being affected by water accumulation, and maintain the stable operation of the equipment. In actual operation, all parts and electrical components in this equipment are equipped with waterproof and insulating structures to improve the safety and stability of the overall equipment during high-altitude de-icing operations.

[0051] In one embodiment, the end of the de-icing rod 520 facing the cable 700 is configured as an ice-crushing surface. This surface is arc-shaped and conforms to the surface of the cable 700, with ice-crushing teeth to improve the de-icing effect of the de-icing rod 520. Specifically, the de-icing assembly 500 also includes a de-icing drive 510, which is connected to the de-icing rod 520 to drive it to reciprocate towards the surface of the cable 700. In this embodiment, the de-icing drive 510 is a vibrator, which can generate unidirectional or multidirectional, harmonic or non-harmonic excitation forces, causing the de-icing rod 520 to vibrate in a certain form and magnitude, thereby effectively breaking up the ice on the surface of the cable 700 and achieving the de-icing effect.

[0052] In one embodiment, the chassis 100 is further provided with a lifting ring 200, which is used to connect the chassis 100 to an external transport device. Specifically, the external transport device can be a high-powered drone, which is equipped with a clamping mechanism for holding the lifting ring 200, so that the operator can remotely control the drone to lift the chassis 100 to the cable 700. The lifting ring 200 is positioned on the side of the chassis 100 opposite to the side where the mounting assembly 300 is located, and / or on the side of the chassis 100 where the mounting assembly 300 is located, so that the mounting assembly 300 can be close to the cable 700 without interfering with the drone. The drone lifts the chassis 100 to the cable 700 and brings the mounting component 300 close to the cable 700. Through the drone's visual mechanism, the fixing component 310 is in the open state and is controlled to contact the cable 700. Then, the second drive component 610 is activated, causing the drive gear 620 to rotate, which in turn drives the transmission gear 630. This causes the two sets of rotating buckles 312 at both ends of the linkage shaft to rotate and lock with the fixing seat 311, securing the cable 700 and completing the fixed connection between the entire device and the cable 700. Finally, the drone is disconnected from the lifting ring 200, and the chassis 100, under gravity, rotates around the cable 700 via the fixing component 310 to its normal operating position.

[0053] By setting up the lifting ring 200, the entire equipment can be hoisted onto the cable 700, which is higher than the ground, by an external transport device for de-icing operations. This avoids the need for manual climbing while carrying heavy loads, which helps to solve the problem of inconvenient installation of many de-icing equipment in traditional operations. It can also effectively reduce the labor intensity of operators and improve operational safety.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
