Description

Technical Field

[0001] This invention relates to the field of de-icing technology, and more specifically, to a de-icing device and its application for de-icing overhead power lines. Background Technology

[0002] Overhead power transmission lines are prone to icing in winter, significantly increasing their weight and placing a load far exceeding normal levels. This can lead to broken strands or wires, and the collapse of poles and towers under the excessive weight, disrupting the power transmission network and causing widespread power outages. Furthermore, wind-driven icing can cause irregular swaying of ice-covered overhead power lines, potentially resulting in phase-to-phase short circuits, disrupting the stable operation of the power system, and causing significant inconvenience to production and daily life. Therefore, to ensure a stable and safe power supply, it is essential to remove ice from overhead power transmission lines promptly.

[0003] For example, CN110556777A discloses a de-icing device, including: a motor device, a roller, a rotating shaft, a motor, a cable, a connecting rod, a connecting shaft, a de-icing device, a heating device, a heating wire, a power supply, and a switching device. This device can heat the ice layer, thereby facilitating the melting of the ice layer during the process, enabling automatic de-icing. However, this device de-icing by melting is slow and ineffective, and has limitations in de-icing.

[0004] Existing methods also employ vibration for de-icing. For example, CN120749636A discloses an "Adaptive Decision Algorithm and De-icing System for Mechanical Vibration De-icing Devices," which generates vibrations matching the natural frequency of the icy line, causing the ice layer to resonate. This vibration effectively breaks the bond between the ice layer and the line surface, thus shaking off the ice or frost. By precisely controlling the vibration frequency and amplitude, damage to the line itself can be minimized, achieving efficient de-icing. However, existing vibration de-icing devices require a fixed point as the vibration base, which needs to be installed on a fixed support, such as near a utility pole or tower, making large-area de-icing impossible.

[0005] For example, CN120855190A discloses a balanced mechanical vibration de-icing device, including a wire crimper for connecting to a suspended linear object. In this design, the de-icing device is mounted on a single suspended linear object and can only de-ic a single overhead power line. Furthermore, the vibrating element in this design includes two eccentric wheels, which share the same drive shaft. However, this method causes eccentric force along the extension direction of the suspended linear object during vibration, making the de-icing device prone to torsion. Moreover, the vibrating element includes four symmetrically balanced eccentric wheels, which easily leads to a complex de-icing device structure. Summary of the Invention

[0006] This invention provides a de-icing device and its application, which can make the de-icing device vibrate itself, causing the line and ice layer to resonate, and under this vibration, the ice or frost layer will be shaken off, and the efficiency of de-icing of overhead transmission lines can be improved.

[0007] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0008] A de-icing device for installation on overhead power transmission lines. Includes a housing and a vibration assembly and a drive assembly disposed within the housing; The vibration assembly includes a first eccentric block and a second eccentric block; The drive assembly includes a drive component, a first rotating shaft connected to the second eccentric block, and a second rotating shaft connected to the first eccentric block, with the second rotating shaft sleeved on the first rotating shaft. The drive component is connected to the first and second rotating shafts respectively via a steering component, and drives the first and second rotating shafts to rotate coaxially and in opposite directions, while simultaneously driving the first and second eccentric blocks to rotate coaxially and in opposite directions. When the first and second eccentric blocks rotate in opposite directions, they generate an eccentric force. Under the action of this eccentric force, the de-icing device vibrates up and down along its center of gravity Z direction, thereby de-icing the overhead power line.

[0009] As a further improvement, the eccentric forces generated by the first and second eccentric blocks during rotation are the same, and the angular velocities of their rotation are the same.

[0010] As a further improvement, the initial positions of the first and second eccentric blocks need to satisfy the following: During the rotation of the first eccentric block and the second eccentric block, the eccentric forces generated by the first eccentric block and the second eccentric block respectively during rotation are superimposed on each other in the Z direction along the center of gravity of the de-icing device; and in the Y direction perpendicular to the center of gravity Z direction and the X direction of the overhead transmission line extension on the horizontal plane, the eccentric forces generated by the first eccentric block and the second eccentric block respectively during rotation cancel each other out.

[0011] As a further improvement, the second rotating shaft is fitted with a first turntable and drives the first turntable to rotate, and the first turntable is used to fix the first eccentric block. A second turntable is fitted onto the first rotating shaft to fix the second eccentric block.

[0012] As a further improvement, the second eccentric block is located on the side of the first eccentric block closer to the center of the first turntable; Alternatively, the first eccentric block may be located on the side of the second eccentric block closer to the center of the second turntable.

[0013] As a further improvement, the steering component includes a second steering wheel, a first steering wheel mounted on a first axle, and a third steering wheel mounted on a second axle; the second steering wheel is connected to both the first and third steering wheels; the driving component is drivenly connected to one of the first, second, and third steering wheels. Preferably, the first steering wheel, the second steering wheel, and the third steering wheel are all bevel gears.

[0014] As a further improvement, the vibration component and the drive component are mounted on the housing via a bracket assembly.

[0015] As a further improvement, the drive assembly also includes a power supply, which is connected to the drive element via a wire, and the power supply and the drive element are located on opposite sides of the vibration assembly.

[0016] As a further improvement, at least one linkage assembly is connected to the outer side of the housing for connection with an overhead power line, and an electromagnetic induction energy harvester is installed at one of the linkage assemblies where it is connected to the overhead power line, the electromagnetic induction energy harvester being electrically connected to a power source.

[0017] The present invention also provides an application of the de-icing device, including the aforementioned de-icing device, wherein the de-icing device is connected to at least one overhead power line; When the first and second rotating shafts rotate in opposite directions on the same axis, they simultaneously drive the first and second eccentric blocks to rotate in opposite directions on the same axis, generating an eccentric force. Under the action of this eccentric force, the de-icing device vibrates up and down along its center of gravity Z direction, thereby de-icing the overhead power transmission line.

[0018] Compared with the prior art, the technical solution provided by this invention has the following advantages: (1) A de-icing device of the present invention includes a vibration assembly, which includes a first eccentric block and a second eccentric block. A driving member is connected to a first rotating shaft and a second rotating shaft via a steering member, driving the first rotating shaft and the second rotating shaft to rotate coaxially in opposite directions. Simultaneously, the first eccentric block is connected to the second rotating shaft, and the second rotating shaft drives the first eccentric block to rotate around the axial center of the second rotating shaft. The second eccentric block is connected to the first rotating shaft, and the first rotating shaft drives the second eccentric block to rotate around the axial center of the first rotating shaft. Since the first rotating shaft and the second rotating shaft rotate coaxially in opposite directions, they respectively drive the first eccentric block and the second eccentric block to rotate coaxially in opposite directions. During the reverse rotation of the first eccentric block and the second eccentric block, the de-icing device itself vibrates along the Z direction of gravity, causing the iced overhead power lines to vibrate simultaneously. Under this vibration, the ice or frost layer is shaken off, achieving efficient de-icing.

[0019] (2) In a de-icing device of the present invention, the first eccentric block and the second eccentric block generate the same eccentric force during rotation. After the initial position is set, the eccentric forces in the Z direction of gravity are superimposed on each other, making it easier for the de-icing device to vibrate in the Z direction to perform de-icing and improve the de-icing effect.

[0020] (3) A de-icing device of the present invention includes a steering component comprising a second steering wheel, a first steering wheel mounted on a first rotating shaft, and a third steering wheel mounted on a second rotating shaft. The steering component enables the driving component to drive the first eccentric block and the second eccentric block to rotate coaxially and in opposite directions.

[0021] (4) In a de-icing device of the present invention, a connecting rod assembly is connected to the outer side of the housing. The connecting rod assembly is used to connect with an overhead power line. At least one connecting rod assembly can be provided, and the de-icing device is installed on at least one overhead power line through the connecting rod assembly, so as to de-ic one or more overhead power lines at the same time. Moreover, when installed on multiple power lines, the setting of the connecting rod assembly enables the de-icing device to not only perform the de-icing function, but also to act as a spacer between the overhead power lines.

[0022] (5) In a de-icing device of the present invention, the driving component further includes a power supply, and the power supply and the driving component are respectively located on both sides of the vibration component to balance the weight on both sides of the vibration component so that the center of the entire de-icing device falls on the vibration component.

[0031] A de-icing device is installed on overhead power lines, such as high-voltage overhead power lines. During winter rain and snow, ice easily forms on overhead power lines, requiring timely de-icing. The de-icing device provided in this application can de-ic by vibration, improving de-icing efficiency.

[0032] Specifically, in combination Figure 1-8 As shown, this application provides a de-icing device.

[0033] See Figure 2 As shown, the de-icing device includes a housing 3 and a vibration component and a drive component disposed in the housing 3.

[0034] See Figure 5 As shown, the vibration assembly includes a first eccentric block 509 and a second eccentric block 511. The drive assembly includes a drive member 402, a first rotating shaft 5051, and a second rotating shaft 5071, with the second rotating shaft 5071 sleeved on the first rotating shaft 5051. The second rotating shaft 5071 and the first rotating shaft 5051 are coaxially arranged. The drive member 402 is connected to the first rotating shaft 5051 and the second rotating shaft 5071 via a steering member, driving the first rotating shaft 5051 and the second rotating shaft 5071 to rotate coaxially in opposite directions. Simultaneously, the first eccentric block 509 is connected to the second rotating shaft 5071, and the second rotating shaft 5071 drives the first eccentric block 509 to rotate around the axial center of the second rotating shaft 5071. The second eccentric block 511 is connected to the first rotating shaft 5051, and the first rotating shaft 5051 drives the second eccentric block 511 to rotate around the axial center of the first rotating shaft 5051.

[0035] Combination Figure 1 and Figure 5 As shown, the de-icing device is installed on the overhead power line 1 during application. The direction of extension of the overhead power line 1 is the X direction, the vertical direction perpendicular to the overhead power line 1 and the direction of gravity of the de-icing device is the Z direction, and the horizontal direction perpendicular to the overhead power line 1 is the Y direction.

[0036] In this application, the first rotating shaft 5051 and the second rotating shaft 5071 rotate coaxially in opposite directions, respectively driving the first eccentric block 509 and the second eccentric block 511 to rotate coaxially in opposite directions. When the first eccentric block 509 and the second eccentric block 511 rotate in opposite directions, they generate eccentric force. Under the action of this eccentric force, the de-icing device vibrates up and down along its center of gravity Z direction, and at the same time drives the overhead power line to vibrate. Under this vibration, ice or frost is shaken off, thus achieving efficient de-icing.

[0037] This de-icing device removes ice through vibration, which is more efficient than existing de-icing methods that rely on thermal melting, eliminating the need for melting. Furthermore, the first eccentric block 509 and the second eccentric block 511 rotate in opposite directions, causing the de-icing device itself to vibrate. This simultaneously vibrates the overhead power line, shaking off ice or frost, resulting in higher de-icing efficiency. Moreover, it eliminates the need for a fixed installation point, allowing the de-icing device to be installed at any location on the overhead power line, thus broadening its application range.

[0038] In this design, the second rotating shaft 5071 is sleeved on the first rotating shaft 5051, so that the first rotating shaft 5051 and the second rotating shaft 5071 are coaxially arranged. At the same time, vibration can be generated by the first eccentric block 509 and the second eccentric block 511 rotating in opposite directions on the same axis, resulting in a more compact structure.

[0039] Combination Figure 7 and Figure 8 As shown, a first turntable 508 is sleeved on the second rotating shaft 5071, and a first eccentric block 509 is fixedly connected to the first turntable 508. A second turntable 510 is sleeved on the first rotating shaft 5051, and a second eccentric block 511 is fixedly connected to the second turntable 510. Specifically, in this embodiment, both the first eccentric block 509 and the second eccentric block 511 are arc-shaped. One end of the first eccentric block 509 is fixedly connected to the first turntable 508, and the first turntable 508 is fixedly mounted on the second rotating shaft 5071. One end of the second eccentric block 511 is fixedly mounted on the second turntable 510, and the second turntable 510 is fixedly mounted on the first rotating shaft 5051. The second rotating shaft 5071 drives the first eccentric block 509 to rotate, and the first rotating shaft 5051 drives the second eccentric block 511 to rotate.

[0040] In this embodiment, the second eccentric block 511 is located on the side of the first eccentric block 509 near the center of the first turntable 508. Taking the side near the first rotating shaft 5051 and the second rotating shaft 5071 as the inner side, the second eccentric block 511 is located inside the first eccentric block 509. To avoid interference, a gap is reserved between the second eccentric block 511 and the first eccentric block 509 to avoid mutual interference.

[0041] It should be noted that in this design, the weight requirements and installation positions of the first eccentric block 509 and the second eccentric block 511 must ensure that the centrifugal force and angular velocity of the two eccentric blocks are the same during rotation. Specifically, the mass of the first eccentric block 509 is m1, the mass of the second eccentric block 511 is m2, the distance from the first eccentric block 509 to the center of the first turntable 508 is R1, and the distance from the second eccentric block 511 to the center of the second turntable 510 is R2. m1 is required. R1=m2 R2.

[0042] In addition, the initial positions of the first eccentric block 509 and the second eccentric block 511 need to satisfy the following: during the rotation of the first eccentric block 509 and the second eccentric block 511, the eccentric forces generated by the first eccentric block 509 and the second eccentric block 511 during rotation are superimposed on each other in the de-icing device along the Z direction of its center of gravity; and in the Y direction perpendicular to the Z direction of the center of gravity and the X direction of the extension of the overhead transmission line 1 on the horizontal plane, the eccentric forces generated by the first eccentric block 509 and the second eccentric block 511 during rotation cancel each other out.

[0043] like Figure 9 As shown, preferably, at the initial position during the first rotation, both the first eccentric block 509 and the second eccentric block 511 are located in the Z direction. During rotation, driven by the second rotating shaft 5071 and the first rotating shaft 5051, the first eccentric block 509 and the second eccentric block 511 rotate coaxially in opposite directions, and the eccentric forces on the first eccentric block 509 and the second eccentric block 511 are the same. The eccentric forces in the Y direction cancel each other out, while the eccentric forces in the Z direction are superimposed on each other, making it easier for the de-icing device to vibrate in the Z direction to perform de-icing.

[0044] In other cases, the initial positions of the first eccentric block 509 and the second eccentric block 511 can also be set to other positions, as long as it satisfies the requirement that during rotation, the eccentric forces generated by the first eccentric block 509 and the second eccentric block 511 respectively are superimposed on each other along the Z-direction of the de-icing device's center of gravity; and that the eccentric forces generated by the first eccentric block 509 and the second eccentric block 511 respectively cancel each other out in the Y-direction perpendicular to the Z-direction of the center of gravity and the X-direction of the overhead transmission line 1 on the horizontal plane. Furthermore, the positions of the two eccentric blocks in the other figures do not represent the positions of the eccentric blocks during rotation; the other figures are only for structural illustration.

[0045] In this design, the first rotating shaft 5051 and the second rotating shaft 5071 are coaxially arranged. The driving component 402 simultaneously drives the first rotating shaft 5051 and the second rotating shaft 5071 to rotate in opposite directions, causing the first eccentric block 509 and the second eccentric block 511 to rotate in opposite directions around the same axis. This generates superimposed vibrations in the Z direction, improving the vibration effect and further causing the ice on the overhead transmission line 1 to fall off, thus improving the de-icing effect. At the same time, the eccentric forces generated by the rotation of the first eccentric block 509 and the second eccentric block 511 in the Y direction cancel each other out, keeping the de-icing device in a balanced state in the Y direction. This prevents the de-icing device from twisting or displacing during vibration in the Z direction, which could damage the overhead transmission line.

[0046] In other embodiments, the first eccentric block 509 may be located on the side of the second eccentric block 511 closer to the center of the second turntable 510. That is, the first eccentric block 509 is located inside the second eccentric block 511, as long as m1 is satisfied. R1=m2 R2 will suffice.

[0047] Combination Figure 5 and Figure 6 As shown, the steering component includes a second steering wheel 506, a first steering wheel 505 mounted on a first rotating shaft 5051, and a third steering wheel 507 mounted on a second rotating shaft 5071; and the second steering wheel 506 is connected to both the first steering wheel 505 and the third steering wheel 507.

[0048] Specifically, the first steering wheel 505, the second steering wheel 506, and the third steering wheel 507 are all bevel gears. The output shaft of the drive unit 402 is connected to the driving wheel 503, which is drively connected to the driven wheel 504. The driven wheel 504 is fixedly connected to the first rotating shaft 5051, and the first steering wheel 505 is also fixedly connected to the first rotating shaft 5051. The third steering wheel 507 is fixedly mounted on the second rotating shaft 5071. The drive unit 402 drives the driven wheel 504 to rotate, and the first rotating shaft 5051 and the first steering wheel 505 rotate simultaneously. When the first steering wheel 505 rotates, it drives the second steering wheel 506 to rotate, thereby driving the third steering wheel 507 to rotate, causing the second rotating shaft 5071 to rotate. Through the first steering wheel 505, the second steering wheel 506, and the third steering wheel 507, the first rotating shaft 5051 and the second rotating shaft 5071 achieve coaxial and counter-rotating rotation. A bearing can be installed between the first rotating shaft 5051 and the second rotating shaft 5071 to enable a rotatable connection between them.

[0049] The arrangement of the three bevel gears—first steering wheel 505, second steering wheel 506, and third steering wheel 507—ensures that the first steering wheel 505 and the third steering wheel 507 rotate in opposite directions, thereby causing the first shaft 5051 and the second shaft 5071 to rotate in opposite directions. It should be noted that the first steering wheel 505, second steering wheel 506, and third steering wheel 507 are of the same size, thus ensuring that the first shaft 5051 and the second shaft 5071 have the same angular velocity.

[0050] In this embodiment, the first steering wheel 505 is connected to the drive member 402 via transmission. However, in other embodiments, the drive member 402 may also be connected to the second steering wheel 506 or the third steering wheel 507 via transmission.

[0051] Combination Figure 2 , Figure 3 and Figure 4 As shown, for fixation, the vibration assembly and the drive assembly are mounted on the housing 3 via a bracket assembly.

[0052] Specifically, the support assembly includes a first fixing plate 501, a second fixing plate 502, a first support frame 512, a second support frame 513, and a third support frame 514. A second fixing plate connection hole 5021 is formed at the center of the second fixing plate 502.

[0053] Both the first fixed disk 501 and the second fixed disk 502 are fixed to the housing 3. The second rotating shaft 5071 passes through the center of the first fixed disk 501 and is supported on the first fixed disk 501. A bearing can be provided between the second rotating shaft 5071 and the first fixed disk 501 to allow the second rotating shaft 5071 to rotate. One end of the first rotating shaft 5051 is supported on the first support frame 512, and the other end is supported on the second fixed disk 502 and rotatably connected in the second fixed disk connecting hole 5021.

[0054] Meanwhile, the first support frame 512 is fixed to the housing 3, and the two ends of the first support frame 512 are respectively connected to the second support frame 513 and the third support frame 514. The other ends of the second support frame 513 and the third support frame 514 are fixedly connected to the first fixed plate 501. Moreover, the driving component 402 is fixedly supported on the first support frame 512.

[0055] Combination Figure 2 and Figure 5 As shown, the drive assembly also includes a power supply 4, which is connected to the drive component 402 via a wire 401. The power supply 4 and the drive component 402 are located on opposite sides of the vibration assembly. Firstly, the drive component 402 can be a motor. The power supply 4 can be a stored energy source. Secondly, the power supply 4 and the drive component 402 are located on opposite sides of the vibration assembly to balance the weight on both sides of the vibration assembly, ensuring that the center of the entire de-icing device rests on the vibration assembly.

[0056] In another preferred embodiment, the drive unit 402 is a variable frequency motor, which can be connected to any existing wireless controller. The wireless controller can interact with a ground control structure, such as a remote control, to control the motor's start / stop and speed. The wireless controller can be a 4G antenna, a Beidou antenna, etc. This method allows for continuous adjustment of the device's vibration frequency until a resonance effect is achieved in the circuit, enabling large-area ice removal and efficient clearing. Furthermore, remote control is enabled, allowing for proactive de-icing initiation at the initial stage of icing or before reaching a dangerous thickness, eliminating potential icing hazards at their inception and transforming passive de-icing into proactive prevention. The motor speed can be continuously adjusted to change the vibration frequency and amplitude until the ice layer breaks off due to fatigue. Adjustments can be made according to the icing situation to ensure the ice layer falls off.

[0057] Combination Figure 1 and Figure 2 As shown, at least one linkage assembly is connected to the outer side of the housing 3. The linkage assembly is used to connect to at least one overhead power line 1. Specifically, the linkage assembly includes a connecting rod and a fixing rod.

[0058] In a preferred embodiment, four connecting rod assemblies are provided, and the de-icing device is connected to four overhead power lines through the connecting rod assemblies. Specifically, the connecting rods include a first connecting rod 21, a second connecting rod 22, a third connecting rod 23, and a fourth connecting rod 24. The fixing rods include a first fixing rod 25, a second fixing rod 26, a third fixing rod 27, and a fourth fixing rod 28. The first connecting rod 21, the second connecting rod 22, the third connecting rod 23, and the fourth connecting rod 24 are all fixedly connected to the outside of the housing 3, and the first connecting rod 21, the second connecting rod 22, the third connecting rod 23, and the fourth connecting rod 24 are symmetrical with respect to the diameter in the Y direction of the first fixing plate 501; the first connecting rod 21, the fourth connecting rod 24, the second connecting rod 22, and the third connecting rod 23 are symmetrical with respect to the diameter in the Z direction of the first fixing plate 501. The first connecting rod 21, the second connecting rod 22, the third connecting rod 23, and the fourth connecting rod 24 are respectively connected to the first fixing rod 25, the second fixing rod 26, the third fixing rod 27, and the fourth fixing rod 28 on the side away from the housing 3. The other ends of the first fixing rod 25, the second fixing rod 26, the third fixing rod 27, and the fourth fixing rod 28 are fixedly connected to different overhead power transmission lines 1.

[0059] The de-icing device is installed on the overhead transmission line 1 by means of a linkage assembly. The linkage assembly enables the de-icing device to not only perform the de-icing function, but also to act as a spacer between the overhead transmission lines, thus achieving functional integration and saving line space and installation costs.

[0060] See Figure 1As shown, this application also provides an application of the de-icing device, including the aforementioned de-icing device, which is connected to the overhead power line 1. When the first rotating shaft 5051 and the second rotating shaft 5071 rotate in opposite directions on the same axis, they simultaneously drive the first eccentric block 509 and the second eccentric block 511 to rotate in opposite directions on the same axis, thereby causing the de-icing device itself to vibrate, and de-icing is performed through this vibration.

[0061] In addition to its application in line de-icing, this device can also actively reduce harmful vibrations such as "micro-wind vibration," "span oscillation," and "galloping" of overhead transmission lines, greatly improving line safety.

[0062] The de-icing device is installed on the overhead transmission line 1, and the power source 4 can also draw power from nearby sources. An electrical connection is established between the overhead transmission line 1 and the power source 4, allowing power to be supplied to the power source 4 without power outages during the de-icing process. This significantly reduces power outages caused by de-icing and ensures the reliability and economic efficiency of the power grid operation. For example, an electromagnetic induction energy harvester can be installed at the connection point between the first fixed pole 25 and the overhead transmission line 1, and connected to the power source 4 to enable the de-icing device to draw power from nearby sources.

[0063] Unless otherwise specified, the terms "installation," "setup," "equipped with," and "connection" used in this application should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; 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, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0064] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
