Description

Technical Field

[0001] This invention relates to the field of overhead line de-icing technology, and more specifically, to a de-icing spacer. Background Technology

[0002] Overhead transmission lines are the carriers of large-capacity, long-distance energy transmission. Large-scale renewable energy bases and ultra-high-voltage transmission lines are under planning and construction. However, due to the adverse weather and terrain conditions along the routes, an increasing number of overhead transmission lines inevitably pass through areas prone to severe icing. Severe icing can cause various accidents to transmission lines, such as mechanical accidents (hardware damage, wire breakage, tower deformation, tower collapse, etc.) and electrical accidents (flashover, short circuit, burns, etc.), seriously affecting the safe operation of the power grid.

[0003] Currently, the main technology for de-icing transmission lines is thermal melting. This involves applying a large current to the conductors, utilizing the Joule heating effect to raise the conductor temperature and melt the surface ice. The advantage of this method is its ability to quickly and over large areas remove ice. However, this method requires a power outage, meaning the grid cannot supply power normally during the de-icing process. This not only affects the continuous power supply, causing interruptions in industrial and residential power use, but may also result in additional economic losses during the outage. Furthermore, frequent power outages for de-icing increase the complexity and cost of grid maintenance, reducing the overall efficiency and reliability of the power system. Summary of the Invention

[0004] The main objective of this invention is to provide a de-icing spacer that can solve the problem that existing power transmission line de-icing methods require power outages during de-icing, which seriously affects the normal operation of the power grid.

[0005] To achieve the above objectives, the present invention provides a de-icing spacer, comprising: a base; a wire clamp for holding a wire; and a de-icing assembly including a mounting base, an impact structure, and a linkage structure. The first end of the mounting base is connected to the base, and the mounting base has a mounting cavity. Both the impact structure and the linkage structure are installed within the mounting cavity and can reciprocate relative to the mounting base along a first direction. The linkage structure is positioned on the movement path of the impact structure, and the wire clamp is positioned at the second end of the mounting base. The impact structure has an impact state and a non-impact state. When the impact structure is in the impact state, it impacts the linkage structure, causing the linkage structure to move the wire clamp relative to the mounting base along the first direction away from the base. When the impact structure is in the non-impact state, the impact structure and the linkage structure have a preset distance. In this state, the linkage structure moves the wire clamp relative to the mounting base along the first direction towards the base until the wire clamp reaches its initial position.

[0006] Furthermore, the linkage structure includes a linkage member and a first elastic member. The first end of the linkage member is connected to the wire clamp, and the second end of the mounting base can form a stop and limit on the linkage member in a first direction. The first elastic member can provide the wire clamp with an elastic restoring force relative to the mounting base in the first direction towards the base to the initial position.

[0007] Furthermore, the first elastic element is a spring, which is sleeved on the linkage element and elastically abuts against the second end of the mounting base and the second end of the linkage element.

[0008] Furthermore, the de-icing spacer also includes a cover body, which is installed on the second end of the mounting base. The cover body can form a stop and limit on the side of the wire clamp facing the base in the first direction. A connecting post is provided on the side of the wire clamp facing the base. A through groove extending in the first direction is provided on the cover body. The connecting post can extend into the through groove and reciprocate relative to the through groove in the first direction. The first end of the linkage is connected to the connecting post. When the wire clamp is in the initial position, the connecting post is located in the through groove.

[0009] Furthermore, the second end of the linkage is provided with a stop protrusion, and the second end of the cover can form a stop limit on the stop protrusion in the first direction. The maximum outer diameter of the linkage on the side of the stop protrusion facing the wire clamp is smaller than the diameter of the through groove.

[0010] Furthermore, the cover is also provided with an installation groove, the through groove is connected to the installation groove, one end of the first elastic member abuts against the bottom wall of the installation groove, and the other end of the first elastic member abuts against the stop protrusion.

[0011] Furthermore, the connecting column is provided with a threaded hole extending in the first direction, and the linkage includes a connecting section and a cylindrical section connected to each other. The connecting section extends into the threaded hole and is threadedly connected to the threaded hole. The first elastic element is a spring, which is sleeved on the cylindrical section. The diameter of the cylindrical section is less than or equal to the diameter of the connecting column.

[0012] Furthermore, there are at least two wire clamps and at least two de-icing components. The at least two wire clamps are arranged at intervals along the circumference of the base, and the at least two wire clamps are set one-to-one with the at least two de-icing components. The wire clamps are set at the second end of the corresponding mounting base.

[0013] Furthermore, the impact structure includes an impact member and a drive structure. The impact member is located on the side of the linkage structure away from the wire clamp. The impact member can reciprocate relative to the mounting base along a first direction. The drive structure is used to drive the impact member to move relative to the mounting base along the first direction away from the base, so that the impact structure switches to the impact state.

[0014] Furthermore, the impact structure also includes a launching tube, which is installed in the mounting cavity. The impact member and the linkage structure are both located inside the launching tube. The driving structure is used to drive the impact member to move in the launching tube along a first direction toward the wire clamp.

[0015] Furthermore, the launching tube is made of insulating material, and the driving structure includes a first coil and a second coil. The first coil is wound around the outer periphery of the impact member, and a winding space is formed between the inner wall surface of the first end of the mounting base and the outer wall surface of the end of the launching tube away from the wire clamp. The second coil is wound around the outer periphery of the launching tube and located in the winding space. The first coil and the second coil are configured to carry currents in opposite directions. And / or, a stop structure extending a predetermined length along a first direction is provided inside the launching tube. The stop structure is located on the side of the impact member away from the wire clamp, and the stop structure can stop and limit the impact member in the first direction.

[0016] Furthermore, the impact structure also includes a second elastic element, one end of which is connected to the impact member, and the other end of which is connected to the first end of the mounting base. The second elastic element is capable of providing the impact member with a force that moves it away from the clamp relative to the mounting base in a first direction.

[0017] Furthermore, the impact structure also includes a guide rod extending along a first direction, the first end of the guide rod being connected to the mounting base, the impact member being sleeved on the guide rod and capable of reciprocating linear motion relative to the guide rod along the first direction, and the guiding length of the guide rod on the impact member being greater than the moving distance of the impact member.

[0018] Furthermore, the second end of the guide rod passes through the linkage structure, and the linkage structure can reciprocate linearly relative to the guide rod in the first direction. The guiding length of the guide rod to the linkage structure is greater than the moving distance of the linkage structure.

[0019] The present invention employs a base, a clamp, and a de-icing assembly. When the impact structure is in an impact state, it impacts the linkage structure, causing the linkage structure to move away from the base along a first direction relative to the mounting base. This, in turn, causes the clamp to move away from the base along the first direction relative to the mounting base. At this time, the kinetic energy of the impact structure is transferred to the clamp through the linkage structure, and then from the clamp to the conductor it holds. This is equivalent to applying an impact force to the conductor in the radial direction. Through this arrangement, a shock wave is generated in the radial direction of the conductor. The shock wave shatters the ice on the conductor, and the shattered ice falls off the conductor, thus achieving de-icing. Unlike thermal de-icing, which requires a power outage to heat the conductor, the de-icing spacer of this application can perform de-icing while the conductor is normally energized, avoiding power outages. This ensures the normal operation of the power grid during de-icing, avoids the power outages required for thermal de-icing, ensures continuous power supply, reduces power supply interruptions, and minimizes the impact on industry and residential life. When the impact structure is in a non-impact state, it is not in contact with the linkage structure. At this time, the linkage structure can move relative to the mounting base along the first direction towards the base, and drive the wire clamp to move relative to the mounting base along the first direction towards the base until the wire clamp returns to its initial position. During the reciprocating motion of the wire clamp relative to the mounting base along the first direction, the conductor is effectively vibrated, causing any broken ice on the guide to fall off completely, ensuring effective de-icing.

[0020] The de-icing spacer of this application has the following advantages:

[0021] 1) It can de-ice the conductor by generating its own impact, without needing to shut down the line, thus reducing the preparation work before de-icing the line.

[0022] 2) The de-icing spacer of this application has a better de-icing effect when the conductor is covered with a thin layer of ice, which solves the previous practice of de-icing when the conductor is covered with ice to the limit;

[0023] 3) This application solves the problem of long-term, continuous de-icing of railway lines, which can be achieved through remote operation by personnel inside the station;

[0024] 4) In the past, thermal de-icing required power outages for de-icing, and the power outage time was limited. In some areas, multiple de-icing operations were required. However, the de-icing spacer in this application does not require power outages, has higher de-icing efficiency, and will not put a lot of work pressure on line maintenance.

[0025] 5) The de-icing spacer of this application can achieve the impact of the diagonal clamp on the conductor. By reducing the number of clamps impacting at the same time, the energy of the impact of a single clamp is increased, thereby achieving a better de-icing effect.

[0026] 6) The de-icing spacer of this application can de-ice when the conductor is covered with a thin layer of ice, and can prevent the conductor from becoming covered with ice through continuous de-icing. Attached Figure Description

Detailed Implementation

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] See also Figures 1 to 12 As shown, the present invention provides a de-icing spacer, which includes: a base 10; a wire clamp 20 for clamping a wire 30; and a de-icing assembly 40, including a mounting base 41, an impact structure 42, and a linkage structure 43. The first end of the mounting base 41 is connected to the base 10, and the mounting base 41 has a mounting cavity 411. The impact structure 42 and the linkage structure 43 are both installed in the mounting cavity 411 and can reciprocate relative to the mounting base 41 in a first direction. The linkage structure 43 is disposed on the moving path of the impact structure 42, and the wire clamp 20 is disposed on the second end of the mounting base 41. The impact structure 42 has an impact state and a non-impact state. When the impact structure 42 is in the impact state, it can impact the linkage structure 43, causing the linkage structure 43 to drive the wire clamp 20 to move away from the base 10 relative to the mounting base 41 along the first direction. When the impact structure 42 is in the non-impact state, the impact structure 42 and the linkage structure 43 have a preset distance. At this time, the linkage structure 43 can drive the wire clamp 20 to move towards the base 10 relative to the mounting base 41 along the first direction until the wire clamp 20 moves to the initial position.

[0044] In this embodiment, the wire clamp 20 is used to clamp the wire 30 to be de-iced. The initial position of the wire clamp 20 refers to the position of the wire clamp 20 on the mounting base 41 when the de-icing spacer has not been de-iced (e.g., ...). Figure 3The initial position of the clamp 20 (where the center clamp is located) is the starting point for the dynamic de-icing action and also the position where the clamp 20 should return after each de-icing action. The first direction refers to the length extension direction of the mounting base 41. Both the impact structure 42 and the linkage structure 43 can reciprocate relative to the mounting base 41 along the first direction, that is, both the impact structure 42 and the linkage structure 43 can move relative to the mounting base 41 along the first direction toward or away from the base 10. Among them, the reciprocating motion of the impact structure 42 relative to the mounting base 41 along the first direction enables the impact structure 42 to switch between the impact state and the non-impact state.

[0045] When the impact structure 42 is in an impact state, it impacts the linkage structure 43, causing the linkage structure 43 to move away from the base 10 relative to the mounting base 41 along the first direction. This, in turn, causes the wire clamp 20 to move away from the base 10 relative to the mounting base 41 along the first direction. At this time, the kinetic energy of the impact structure 42 is transferred to the wire clamp 20 through the linkage structure 43, and then from the wire clamp 20 to the conductor 30 it holds. This is equivalent to applying an impact force to the conductor 30 in the radial direction. Through the above arrangement, a shock wave can be generated in the radial direction of the conductor 30. The shock wave breaks the ice on the conductor 30, and the broken ice falls off the conductor 30, thereby achieving de-icing of the conductor 30. Compared to the de-icing method that requires power outage to heat the conductors for thermal de-icing, the de-icing spacer of this application can perform de-icing while the conductor 30 is normally energized, avoiding power outage operations. This ensures the normal operation of the power grid during the de-icing process, avoids the power outage operations required for thermal de-icing, ensures continuous power supply to the power grid, reduces power supply interruptions, reduces the impact on industrial and residential life, and ensures the commissioning rate of transmission lines.

[0046] When the impact structure 42 is in a non-impact state, it is not in contact with the linkage structure 43. At this time, the linkage structure 43 can move relative to the mounting base 41 along the first direction towards the base 10, and drive the wire clamp 20 to move relative to the mounting base 41 along the first direction towards the base 10 until the wire clamp 20 returns to its initial position. During the reciprocating motion of the wire clamp 20 relative to the mounting base 41 along the first direction, it effectively vibrates the conductor 30, causing the broken ice on the conductor 30 to fall off completely, ensuring a proper de-icing effect.

[0047] In one embodiment, when the impact structure 42 is in a non-impact state, the preset distance between the impact structure 42 and the linkage structure 43 is in the range of 30mm to 80mm. This setting can provide sufficient movement space for the next impact of the impact structure 42.

[0048] See also Figures 1 to 12As shown, in one embodiment of the present invention, the linkage structure 43 includes a linkage member 431 and a first elastic member 433. The first end of the linkage member 431 is connected to the wire clamp 20. The second end of the mounting base 41 can form a stop and limit the linkage member 431 in a first direction. The first elastic member 433 can provide the wire clamp 20 with an elastic restoring force relative to the mounting base 41 in the first direction towards the base 10 to the initial position.

[0049] In this embodiment, the second end of the mounting base 41 can stop and limit the linkage 431 in the first direction, preventing the linkage 431 from coming out of the mounting cavity 411. When the impact structure 42 is in an impact state, the impact structure 42 can impact the linkage 431, causing the linkage 431 to move relative to the mounting base 41 in the first direction away from the base 10. Since the first end of the linkage 431 is connected to the wire clamp 20, the linkage 431 can transmit the impact force of the impact structure 42 to the wire clamp 20, and cause the wire clamp 20 to drive the conductor 30 to move in the first direction away from the base 10. The impact force can break the ice layer on the surface of the conductor 30, achieving the purpose of de-icing.

[0050] When the impact structure 42 is in a non-impact state, it is not in contact with the linkage 431. At this time, the linkage 431 can move relative to the mounting base 41 in the first direction toward the base 10, and drive the wire clamp 20 to move relative to the mounting base 41 in the first direction toward the base 10 until the wire clamp 20 returns to its initial position. During the reciprocating motion of the wire clamp 20 relative to the mounting base 41 in the first direction, the conductor 30 is actually shaken, so that the ice on the conductor 30 can be completely shaken off, ensuring the de-icing effect.

[0051] The first elastic element 433 provides the wire clamp 20 with the ability to automatically reset. After the de-icing action is completed, the first elastic element 433 can provide the wire clamp 20 with an elastic restoring force relative to the mounting base 41 in the first direction towards the base 10 to the initial position, so that the wire clamp 20 can quickly return to the initial position without manual adjustment or external intervention, thereby realizing the automation and continuity of the de-icing process.

[0052] See also Figures 1 to 12 As shown, in one embodiment of the present invention, the first elastic element 433 is a spring, the first elastic element 433 is sleeved on the linkage element 431, and the first elastic element 433 elastically abuts against the second end of the mounting base 41 and the second end of the linkage element 431.

[0053] In this embodiment, when the impact structure 42 is in an impact state, the impact structure 42 can impact the linkage 431, causing the linkage 431 to move away from the base 10 relative to the mounting base 41 along the first direction. At this time, the spring is compressed. After the impact action is completed, the elastic restoring force of the spring can cause the linkage 431 to move towards the base 10 relative to the mounting base 41 along the first direction, and drive the wire clamp 20 to move towards the base 10 along the first direction, returning to its initial position.

[0054] The above settings enable automatic reset of the clamp 20, eliminating the need for manual adjustment or external power, and improving the automation level and operational efficiency of the de-icing spacer. The spring's elastic properties also provide cushioning and vibration damping, reducing the direct damage to the internal structure and wire 30 caused by the impact force generated during de-icing. Especially under frequent de-icing conditions, the spring's vibration damping effect significantly reduces the stress and vibration experienced by the device, enhancing its durability and reliability.

[0055] In one embodiment, the first elastic element 433 is a compression spring.

[0056] See also Figures 1 to 12 As shown, in one embodiment of the present invention, the de-icing spacer also includes a cover 50, which is disposed on the second end of the mounting base 41. The cover 50 can form a stop and limit on the side of the wire clamp 20 facing the base 10 in a first direction. A connecting post 21 is provided on the side of the wire clamp 20 facing the base 10. A through groove 51 extending along the first direction is provided on the cover 50. The connecting post 21 can extend into the through groove 51 and reciprocate relative to the through groove 51 in the first direction. The first end of the linkage 431 is connected to the connecting post 21. When the wire clamp 20 is in the initial position, the connecting post 21 is located in the through groove 51.

[0057] In this embodiment, the cover 50 not only provides a stop and limit for the linkage 431 in the first direction, preventing the linkage 431 from dislodging from the mounting cavity 411, but also provides a stop and limit for the wire clamp 20 in the first direction. When the wire clamp 20 and the cover 50 form a stop and limit, the wire clamp 20 is in its initial position and can be maintained in its initial position. The connecting post 21 enables the connection between the linkage 431 and the wire clamp 20. The connecting post 21 can extend into the through groove 51 and reciprocate relative to the through groove 51 in the first direction, so that the linkage 431 can drive the wire clamp 20 to move relative to the mounting base 41 in the first direction toward or away from the base 10, thereby achieving de-icing.

[0058] In one embodiment, both the impact structure 42 and the linkage structure 43 can reciprocate linearly relative to the mounting base 41 along the first direction. When the impact structure 42 is in an impact state, it can impact the linkage structure 43, causing the linkage structure 43 to move away from the base 10 relative to the mounting base 41 along the first direction, and driving the wire clamp 20 to move away from the base 10 relative to the mounting base 41 along the first direction. At this time, the kinetic energy of the impact structure 42 is transferred to the wire clamp 20 through the linkage structure 43, and then from the wire clamp 20 to the wire 30 it holds. This is equivalent to applying an impact force to the wire 30 in the radial direction, breaking the ice on the wire 30, and the broken ice falls off the wire 30, thereby achieving the de-icing of the wire 30.

[0059] When the impact structure 42 is in a non-impact state, it is not in contact with the linkage structure 43. At this time, the linkage structure 43 can move relative to the mounting base 41 along the first direction towards the base 10, and drive the wire clamp 20 to move relative to the mounting base 41 along the first direction towards the base 10 until the wire clamp 20 returns to its initial position. As can be seen from the above, with the cooperation of the impact structure 42 and the linkage structure 43, the wire clamp 20 can perform reciprocating linear motion along the first direction, achieving vibration of the wire 30 in the radial direction and ensuring the de-icing effect.

[0060] See also Figures 1 to 12 As shown, in one embodiment of the present invention, the second end of the linkage 431 is provided with a stop protrusion 432, and the second end of the cover 50 can form a stop limit on the stop protrusion 432 in the first direction. The maximum outer diameter of the linkage 431 on the side of the stop protrusion 432 facing the wire clamp 20 is smaller than the diameter of the through groove 51.

[0061] In this embodiment, the stop protrusion 432 and the second end of the cover 50 limit the movement range of the linkage 431 along the first direction, preventing the linkage 431 from dislodging from the mounting cavity 411. The portion of the linkage 431 located on the side of the stop protrusion 432 facing the wire clamp 20 has a maximum outer diameter smaller than the diameter of the through groove 51, ensuring that this portion can move within the through groove 51 along the first direction, thereby enabling the wire clamp 20 to reciprocate relative to the mounting base 41 along the first direction.

[0062] See also Figures 1 to 12 As shown, in one embodiment of the present invention, the cover 50 is further provided with an installation groove 52, the through groove 51 is connected to the installation groove 52, one end of the first elastic member 433 abuts against the bottom wall of the installation groove 52, and the other end of the first elastic member 433 abuts against the stop protrusion 432.

[0063] In this embodiment, the through groove 51 extends along the first direction to the mounting groove 52. At this time, the through groove 51 penetrates the bottom wall of the mounting groove 52. In this way, the first end of the linkage 431 can extend into the through groove 51 through the mounting groove 52 and connect with the connecting post 21 of the wire clamp 20, thereby realizing the connection between the wire clamp 20 and the linkage 431. The first elastic element 433 elastically abuts against the bottom wall of the mounting groove 52 and the stop protrusion 432. When the impact structure 42 is in an impact state, the impact structure 42 can impact the linkage element 431, causing the linkage element 431 to move relative to the mounting base 41 in the first direction away from the base 10. Since the first end of the linkage element 431 is connected to the wire clamp 20, the linkage element 431 can drive the wire clamp 20 to move in the first direction away from the base 10. At this time, the first elastic element 433 is compressed. After the impact, the elastic restoring force of the first elastic element 433 can cause the linkage element 431 to drive the wire clamp 20 to move in the opposite direction in the first direction until the wire clamp 20 returns to its initial position.

[0064] See also Figures 1 to 12 As shown, in one embodiment of the present invention, the connecting post 21 is provided with a threaded hole 211 extending in a first direction, and the linkage 431 includes a connecting section 4311 and a cylindrical section 4312 connected to each other. The connecting section 4311 extends into the threaded hole 211 and is threadedly connected to the threaded hole 211. The first elastic member 433 is a spring and is sleeved on the cylindrical section 4312. The diameter of the cylindrical section 4312 is less than or equal to the diameter of the connecting post 21.

[0065] In this embodiment, the connecting segment 4311 and the threaded hole 211 on the connecting post 21 form a threaded connection, which not only connects the wire clamp 20 to the linkage 431, but also allows adjustment of the position of the linkage 431 in the first direction by rotating the linkage 431, thereby adjusting the spring compression and changing the spring preload. This ensures that the de-icing action is powerful and effective without causing excessive damage to the wire 30 or the device itself. The cylindrical segment 4312 provides installation space for the spring and also guides the spring to prevent lateral deviation. The diameter of the cylindrical segment 4312 is less than or equal to the diameter of the connecting post 21, ensuring that the cylindrical segment 4312 can slide smoothly in the through groove 51 along the first direction.

[0066] See also Figures 1 to 12 As shown, in one embodiment of the present invention, the connecting post 21 is adapted to the through groove 51, and the outer wall surface of the connecting post 21 is in contact with the inner wall surface of the through groove 51. This can prevent the connecting post 21 from shifting during the sliding process along the first direction in the through groove 51. At the same time, the through groove 51 can also support the wire clamp 20 and ensure the structural stability of the wire clamp 20.

[0067] Currently, mechanical de-icing involves striking the conductors, causing the ice-covered conductors to break and fall off under the action of vibration waves. This method can maintain power supply, but the de-icing efficiency is low, especially for multi-branched conductors where it is difficult to strike all of them. Furthermore, due to the installation of damping spacers, striking one sub-conductor is unlikely to effectively de-ic the others. To solve these problems, [see reference...] Figures 1 to 12 As shown, in one embodiment of the present invention, there are at least two wire clamps 20 and at least two de-icing components 40. The at least two wire clamps 20 are arranged at intervals along the circumference of the base 10. The at least two wire clamps 20 are correspondingly arranged with the at least two de-icing components 40. The wire clamps 20 are disposed at the second end of the corresponding mounting base 41.

[0068] In this embodiment, there are at least two wire clamps 20 and at least two de-icing components 40, which can de-ic the at least two wires 30, improving the de-icing efficiency. At the same time, since there is a one-to-one correspondence between the wire clamps 20 and the de-icing components 40, the impact force on each wire clamp 20 can be independently controlled by the corresponding de-icing component 40. That is, the de-icing operation on different wires 30 is independent of each other and does not interfere with each other. Different degrees of de-icing can be performed according to the ice accumulation on each wire 30.

[0069] See also Figures 1 to 12 As shown, in one embodiment of the present invention, the impact structure 42 includes an impact member 421 and a driving structure. The impact member 421 is located on the side of the linkage structure 43 away from the wire clamp 20. The impact member 421 can reciprocate relative to the mounting base 41 in a first direction. The driving structure is used to drive the impact member 421 to move relative to the mounting base 41 in a direction away from the base 10 in the first direction, so that the impact structure 42 switches to the impact state.

[0070] In this embodiment, the driving structure is used to drive the impact member 421 to move away from the base 10 in the first direction relative to the mounting base 41, so that the impact structure 42 switches to the impact state. When the impact structure 42 is in the impact state, the impact member 421 can impact the linkage structure 43, so that the linkage structure 43 moves away from the base 10 in the first direction relative to the mounting base 41, and drives the wire clamp 20 to move away from the base 10 in the first direction relative to the mounting base 41. At this time, the kinetic energy of the impact structure 42 is transmitted to the wire clamp 20 through the linkage structure 43, and then from the wire clamp 20 to the wire 30 it holds. This is equivalent to applying an impact force to the wire 30 in the radial direction of the wire 30.

[0071] With the above configuration, a shock wave can be generated in the radial direction of the conductor 30. The shock wave breaks the ice on the conductor 30, and the broken ice falls off the conductor 30, thereby achieving de-icing of the conductor 30. When the impact structure 42 is in a non-impact state, the impact member 421 is not in contact with the linkage structure 43. At this time, the linkage structure 43 can move relative to the mounting base 41 in the first direction toward the base 10, and drive the wire clamp 20 to move relative to the mounting base 41 in the first direction toward the base 10 until the wire clamp 20 returns to its initial position.

[0072] See also Figures 1 to 12 As shown, in one embodiment of the present invention, the impact structure 42 further includes a launching tube 422, which is installed in the mounting cavity 411. The impact member 421 and the linkage structure 43 are both located in the launching tube 422. The driving structure is used to drive the impact member 421 to move in the launching tube 422 along a first direction toward the wire clamp 20.

[0073] In this embodiment, the mounting base 41 provides a first layer of physical protection for the impact member 421 and the linkage structure 43, while the launching tube 422 provides a second layer of physical protection for the impact member 421 and the linkage structure 43. The driving structure enables the impact member 421 to move within the launching tube 422 in a first direction toward the wire clamp 20, thereby impacting the linkage structure 43.

[0074] See also Figures 1 to 12 As shown, in one embodiment of the present invention, the launching tube 422 is made of insulating material, and the driving structure includes a first coil and a second coil. The first coil is wound around the outer periphery of the impact member 421. A winding space 90 is formed between the inner wall surface of the first end of the mounting base 41 and the outer wall surface of the end of the launching tube 422 away from the wire clamp 20. The second coil is wound around the outer periphery of the launching tube 422 and located in the winding space 90. The first coil and the second coil are configured to carry currents in opposite directions.

[0075] In this embodiment, the launch tube 422 is fixedly disposed within the mounting cavity 411. The launch tube 422 is made of insulating material, which enables electrical isolation between the impact member 421 and other metal components outside the launch tube 422. Simultaneously, the insulating material resists electro-corrosion under harsh weather conditions, extending the service life of the launch tube 422.

[0076] The first coil is wound around the outer circumference of the impact member 421 in a first direction, and the second coil is wound around the outer circumference of the launching tube 422 in the same first direction. By passing currents in opposite directions to the first and second coils, magnetic fields in opposite directions are generated between them. Since the launching tube 422 is stationary, the repulsive force causes the impact member 421 to move towards the clamp 20 in the first direction, thereby impacting the linkage structure 43. This electromagnetic drive method not only has a fast response speed, generating high-intensity impacts in a short time, but also provides precise control. The speed and impact force of the impact member 421 can be precisely controlled by adjusting the current, improving de-icing efficiency and effect.

[0077] It should be noted that a certain length (spiral winding) is reserved in the first coil to avoid affecting the movement of the impact member 421. Existing technology can be used to achieve the flow of current in opposite directions to the first and second coils; the specific structure will not be described here.

[0078] In one embodiment, the impact member 421 is made of a magnetic metal, such as iron, steel, nickel alloy, silicon steel alloy, etc.

[0079] See also Figures 1 to 12 As shown, in one embodiment of the present invention, a stop structure 4221 extending a predetermined length in a first direction is provided inside the launching tube 422. The stop structure 4221 is located on the side of the impact member 421 away from the wire clamp 20, and the stop structure 4221 can stop and limit the impact member 421 in the first direction.

[0080] In this embodiment, the stop structure 4221 can stop and limit the impact member 421 in the first direction, so as to prevent the impact member 421 from getting too close to the base 10.

[0081] See also Figures 1 to 12 As shown, in one embodiment of the present invention, the impact structure 42 further includes a second elastic member 423. One end of the second elastic member 423 is connected to the impact member 421, and the other end of the second elastic member 423 is connected to the first end of the mounting base 41. The second elastic member 423 can provide the impact member 421 with a force that moves it away from the clamp 20 relative to the mounting base 41 in a first direction.

[0082] In this embodiment, when the impact structure 42 moves away from the base 10 along the first direction relative to the mounting base 41, the second elastic element 423 is stretched and deformed. After the impact element 421 impacts the linkage structure 43, it provides a force to the impact element 421 to move away from the clamp 20 along the first direction relative to the mounting base 41, causing the impact element 421 to reset to its initial position and prepare for the next impact, significantly improving the continuous de-icing capability and de-icing efficiency. The second elastic element 423 ensures that the reset process of the impact element 421 after each impact does not rely on external energy input, reducing the requirements for the device's energy storage and power supply systems, thereby reducing energy loss and improving the overall energy efficiency of the device.

[0083] In one embodiment, the second elastic element 423 is a tension spring.

[0084] See also Figures 1 to 12 As shown, in one embodiment of the present invention, the impact structure 42 further includes a guide rod 424 extending along a first direction. The first end of the guide rod 424 is connected to the mounting base 41. The impact member 421 is sleeved on the guide rod 424 and can reciprocate linearly relative to the guide rod 424 along the first direction. The guiding length of the guide rod 424 on the impact member 421 is greater than the moving distance of the impact member 421.

[0085] In this embodiment, the guide rod 424 can guide the impact member 421 in the first direction, ensuring that the impact member 421 can reciprocate linearly along the first direction, avoiding the impact member 421 from deviating during the movement along the first direction, and ensuring the stability and accuracy of the movement of the impact member 421.

[0086] See also Figures 1 to 12 As shown, in one embodiment of the present invention, the second end of the guide rod 424 passes through the linkage structure 43, and the linkage structure 43 is capable of reciprocating relative to the guide rod 424 in a first direction. The guiding length of the guide rod 424 to the linkage structure 43 is greater than the moving distance of the linkage structure 43.

[0087] In this embodiment, the guide rod 424 can guide the linkage structure 43 in the first direction, ensuring that the linkage structure 43 can reciprocate linearly along the first direction, avoiding deviation of the linkage structure 43 during the movement along the first direction, and ensuring the stability and accuracy of the movement of the linkage structure 43.

[0088] See also Figures 1 to 12As shown, in one embodiment of the present invention, the de-icing spacer also includes an annular frame 60, the base 10 is located on the inner circumferential side of the annular frame 60, the second end portion of the mounting base 41 is located on the outer circumferential side of the annular frame 60, the annular frame 60 can support the second end of the mounting base 41, and the annular frame 60 can form an anti-detachment limit on the second end of the mounting base 41 in a first direction, and the wire clamp 20 is located on the outer circumferential side of the annular frame 60.

[0089] In this embodiment, the annular frame 60 supports the second end of the mounting base 41. Simultaneously, the annular frame 60 provides anti-detachment restraint to the second end of the mounting base 41 in the first direction, ensuring that the de-icing spacer can withstand frequent impacts without structural damage or deformation, thus extending its service life. The wire clamp 20 is located on the outer periphery of the annular frame 60, facilitating the clamping of the wire 30.

[0090] See also Figures 1 to 12 As shown, in one embodiment of the present invention, the annular frame 60 includes a first annular subframe 61 and a second annular subframe 62 stacked together, a clamping space is formed between the first annular subframe 61 and the second annular subframe 62, and the second end portion of the mounting base 41 is located within the clamping space.

[0091] In this embodiment, a clamping space is formed between the first annular sub-frame 61 and the second annular sub-frame 62, which can more firmly clamp the second end of the mounting base 41. Compared with a single annular frame, this double-layer design provides a stronger anti-detachment and limiting effect, ensuring that the mounting base 41 will not detach from the annular frame 60 even under high-intensity impact or extreme weather conditions, thus enhancing the safety and stability of the entire device. The first annular sub-frame 61 and the second annular sub-frame 62 are independent of each other, allowing the annular frame 60 to be disassembled into two independent parts, facilitating on-site assembly and maintenance.

[0092] See also Figures 1 to 12 As shown, in one embodiment of the present invention, the wire clamp 20 includes a wire clamp cover 22, a wire clamp body 23, and a swivel bolt 24. One end of the wire clamp body 23 is hinged to one end of the wire clamp cover 22. The wire clamp cover 22 is openable and closable relative to the wire clamp body 23. The other end of the wire clamp body 23 is connected to the other end of the wire clamp cover 22 by the swivel bolt 24. One end of the swivel bolt 24 is connected to the wire clamp cover 22. The other end of the swivel bolt 24 passes through the wire clamp body 23 and is locked by a nut. At this time, the wire 30 can be clamped.

[0093] See also Figures 1 to 12As shown, in one embodiment of the present invention, the de-icing spacer also includes a protective cover support cover 80. The support cover 80 is disposed at the first end of the mounting base 41. The first end of the guide rod 424 extends through the support cover 80. The portion of the guide rod 424 extending through the support cover 80 is threaded and can be locked with a nut to achieve connection with the support cover 80.

[0094] See also Figures 1 to 12 As shown, in one embodiment of the present invention, the de-icing spacer also includes an energy storage device, a control system, a protective cover 70, and an energy harvesting device. The energy storage device can be recharged via the energy harvesting device. The base 10 has a receiving cavity and an opening communicating with the receiving cavity. Both the energy storage device and the control system are installed within the receiving cavity through the opening. After installation, the protective cover 70 covers the opening to seal it. The energy storage device and the control system are communicatively connected. The energy harvesting module is installed on a wire and transmits electrical energy to the energy storage device via inductive power extraction. The charging and discharging of the energy storage device can be controlled by the control system.

[0095] It should be noted that the energy harvesting module and energy storage device mentioned above can both adopt existing technologies, and their specific structures will not be described in detail here.

[0096] In one embodiment, the energy storage device includes a capacitor. The support cover 80 is provided with two first wire outlet holes 81, so that the wire outlets of the first coil and the second coil can be connected to the energy storage device. The impact member 421 is provided with a second wire outlet hole 4211 and a third wire outlet hole 4212 at the end away from the linkage structure 43. One of the first wire outlet holes 81 is provided corresponding to the second wire outlet hole 4211, and the other first wire outlet hole 81 is provided corresponding to the third wire outlet hole 4212. The first coil is wound around the outer periphery of the impact member 421. One end of the first coil passes through the second wire outlet hole 4211 and the corresponding first wire outlet hole 81 in sequence, exits the mounting cavity 411, and is electrically connected to the positive terminal of the capacitor. The other end of the first coil passes through the third wire outlet hole 4212 and the corresponding first wire outlet hole 81 in sequence, exits the mounting cavity 411, and is electrically connected to the negative terminal of the capacitor.

[0097] The mounting base 41 is provided with a fourth outlet hole 412 and a fifth outlet hole 413 communicating with the winding space 90. The second coil is wound around the transmitting tube 422. One end of the second coil passes through the fourth outlet hole 412 and exits the mounting base 41, then is electrically connected to the positive terminal of the capacitor. The other end of the second coil passes through the fifth outlet hole 413 and exits the mounting base 41, then is electrically connected to the negative terminal of the capacitor. With the above arrangement, currents in opposite directions can be passed to the first coil and the second coil.

[0098] In one embodiment of the present invention, the energy harvesting device is a CT power harvesting device.

[0099] In one embodiment of the present invention, the base 10 is a polygonal structure. The shape of the base 10 can be determined according to the number of split conductors (referring to conductors 30) of the transmission line. For example, if the number of split conductors is four, the base 10 is a regular quadrilateral; if the number of split conductors is six, the base 10 is a regular hexagon; and if the number of split conductors is eight, the base 10 is a regular octagon.

[0100] In one embodiment, there are two protective covers 70 and two openings on the base 10. The two protective covers 70 are arranged one-to-one with the two openings, and the protective covers 70 cover the corresponding openings and seal with the openings. The protective covers 70 are bolted to the base 10.

[0101] In one embodiment, the cover 50 is threadedly connected to the mounting base 41, and the cover 50 and the mounting base 41 are sealed together by a sealing ring.

[0102] In one embodiment, the launch tube is made of a non-metallic material, which reduces the magnetic field shielding of the second coil and ensures the reaction force with the first coil.

[0103] In one embodiment, grooves are provided on the outer periphery of both the launching tube and the impact member. The first coil is wound around the outer periphery of the impact member 421 through the grooves, and the second coil is wound around the outer periphery of the launching tube through the grooves. The energy storage device includes a capacitor, and the two ends of the first coil and the second coil are connected to the positive and negative terminals of the capacitor. The energy storage device supplies opposite currents to the first coil and the second coil.

[0104] In one embodiment, the accommodating cavity of the base 10 is equipped with multiple electromagnetic guns with coils. By rapidly releasing the large current generated by the electrical energy stored in the spacer bar, the impacting element impacts the linkage structure, and the impact force is transmitted to the wire clamp through the linkage structure to achieve the purpose of de-icing.

[0105] In one embodiment, the control system also integrates a communication module, which enables communication between adjacent de-icing spacers. Through remote control, the de-icing action of a single de-icing spacer or multiple de-icing spacers can be achieved. The communication module can adopt existing technology.

[0106] In one embodiment, the de-icing spacer can be combined with an existing online monitoring system for transmission lines. When the online monitoring system detects icing on the line, it can remove the ice through the de-icing spacer, thereby achieving automatic de-icing of the transmission line, improving the transmission line's resistance to icing, and greatly contributing to the improvement of the power grid's intelligence and safe operation.

[0107] It should be noted that the de-icing spacers can be installed in the line span using the same methods as existing de-icing spacer installation techniques to ensure that every section of conductor in the span can be de-iced by the de-icing spacers. The de-icing spacers of this application are based on mechanical de-icing, and by installing de-icing spacers in each span of the line, high de-icing efficiency can be achieved, and the electrical energy of the conductor is extracted and stored inside the de-icing spacers.

[0108] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: A base, a clamp, and a de-icing assembly are provided. When the impact structure is in an impact state, the impact structure can impact the linkage structure, causing the linkage structure to move away from the base relative to the mounting base along a first direction, and driving the clamp to move away from the base relative to the mounting base along the first direction. At this time, the kinetic energy of the impact structure is transferred to the clamp through the linkage structure, and then from the clamp to the conductor it holds. This is equivalent to applying an impact force to the conductor in the radial direction. Through the above arrangement, a shock wave can be generated in the radial direction of the conductor. The shock wave shatters the ice on the conductor, and the shattered ice falls off the conductor, thereby achieving de-icing of the conductor. Unlike thermal de-icing, which requires power outage to heat the conductor, the de-icing spacer of this application can perform de-icing while the conductor is normally energized, avoiding power outage operations. This ensures the normal operation of the power grid during the de-icing process, avoids the power outage operations required for thermal de-icing, ensures continuous power supply to the power grid, reduces power supply interruptions, and minimizes the impact on industrial and residential life. When the impact structure is in a non-impact state, it is not in contact with the linkage structure. At this time, the linkage structure can move relative to the mounting base along the first direction towards the base, and drive the wire clamp to move relative to the mounting base along the first direction towards the base until the wire clamp returns to its initial position. During the reciprocating motion of the wire clamp relative to the mounting base along the first direction, the conductor is effectively vibrated, causing any broken ice on the guide to fall off completely, ensuring effective de-icing.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
