Description

Technical Field

[0001] The invention relates to the technical field of electric power protection hardware, in particular to a rotary wire clamp for an anti-dancing spacer rod. Background Art

[0002] Spacers are hardware fixtures installed on split conductors to stabilize the spacing between them. This prevents whiplash and suppresses breeze vibration and sub-span oscillation. They are typically installed in the middle of a span, with one installed every 50-60 meters. The primary function of spacers is to maintain the relative position of the sub-conductors within a split conductor, ensuring stable spacing between them and improving the stability and safety of the transmission line.

[0003] The ends of the spacers are connected to the conductors via wire clamps. To prevent eccentric ice accumulation on the conductors and prevent transmission line galloping, a swivel wire clamp is currently used to achieve the effect of rotating the conductors along their axis. However, existing swivel wire clamps often achieve this by sliding a guide cable within a circumferential guide groove in the outer casing. This method is prone to significant wear and friction, and is also prone to freezing in icy and snowy weather, preventing the conductors from sliding and effectively preventing galloping. Summary of the Invention

[0004] The purpose of the present invention is to provide a rotary wire clamp for anti-dancing spacer bars, which reduces friction resistance and contact area by arranging rollers between an inner sleeve and an outer sleeve, reduces the influence of freezing, and improves the rotation effect.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The present invention provides a rotary wire clamp for an anti-dancing spacer rod, comprising a main wire clamp housing, a wire clamp buckle cover housing, a locking pin, a roller and a cable kit. The wire clamp buckle cover housing and the main wire clamp housing are rotatably connected via a pin shaft at the top; a through hole for passing the locking pin is provided at the bottom of the wire clamp buckle cover housing and the top of the main wire clamp housing handle; a cable hole for clamping a wire is provided in the middle of the cable kit; a plurality of rollers are arranged on the inner walls of the main wire clamp housing and the wire clamp buckle cover housing, and the inner sides of the rollers rollingly support the outer wall of the cable kit.

[0007] Furthermore, the cable kit includes a cable half sleeve and an inner hoop half sleeve, the cable half sleeve is made of rubber material, the two cable half sleeves are buckled to form the cable hole, and the two inner hoop half sleeves are tightened to the outside of the two cable half sleeves by bolts; the inner hoop half sleeve is supported by the roller in a rolling manner.

[0008] Furthermore, the end face of the cable half sleeve is provided with a rib extending outward, and the rib is limited on the end face of the inner hoop half sleeve; a limiting boss is provided on the outer wall of the inner hoop half sleeve, the longitudinal section of the roller is I-shaped, and the limiting boss is clamped in the annular groove of the outer wall of the roller.

[0009] Furthermore, the plurality of rollers are arranged into two rows along the axial direction of the cable hole, and the plurality of rollers in each row are arranged at equal intervals along the circumferential direction; the two coaxially arranged rollers are installed on the inner folding edge of the main wire clamp shell or the wire clamp buckle cover shell through the roller shaft.

[0010] Furthermore, a plurality of water leakage holes are provided on the shell plate of the main wire clamp shell or the wire clamp buckle cover shell; the water leakage holes are long holes located outside the roller, and the number of the water leakage holes is the same as the number of the rollers.

[0011] Furthermore, the handle end of the main line clamp housing is provided with a mounting hole 1 and a mounting hole 2, and the mounting hole 1 and the mounting hole 2 are connected to the protruding end of the spacer rod through a pin.

[0012] Furthermore, a water blocking disk is integrally provided on the outer edge of the outer end surface of the retaining edge. The water blocking disk is tilted outward and the outer edge diameter is larger than the diameter of the inner folding edge of the main wire clamp shell and the wire clamp buckle cover shell.

[0013] Furthermore, it also includes a vibrating assembly, a shifting tooth is provided in the middle position of the outer wall of the inner hoop half sleeve, and the number of the vibrating assemblies is two, which are respectively provided on the inner folding edges of the main wire clamp shell and the wire clamp buckle cover shell. The vibrating assembly is provided on the inner folding edge between the two rows of rollers, and the working end of the vibrating assembly can be vibrated by the shifting tooth.

[0014] Furthermore, the vibration starting assembly includes a mounting seat, a spring and an impact head. A vibration component mounting hole is provided on the inner folding edge of the main line clamp shell. The mounting seat is fixedly connected to the outer end of the vibration component mounting hole. The outer end of the spring is connected to the inner side surface of the mounting seat and the inner end is connected to the impact head; the impact head can contact the shifting tooth.

[0015] Furthermore, the number of the shifting teeth is multiple and they are evenly distributed along the circumference of the outer wall of the inner hoop half sleeve; the inner end of the vibration component mounting hole facing the cable hole is set as a half bell mouth.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] The rotary wire clamp of the anti-dancing spacer rod of the present invention can smoothly remove or install the cable kit after opening by arranging a main wire clamp shell and a wire clamp buckle cover shell connected by a pin shaft; the cable kit is supported by rollers, the rolling friction resistance is small, the rotation resistance of the wire is reduced, and the anti-dancing effect is good.

[0018] In addition, the split cable half-sheath and inner hoop half-sheath allow for flexible installation of the wire clamp at the desired location. The docking plug and docking slot allow the inner hoop half-sheath to be positioned for quick installation. The retaining edge, positioned on the end face of the inner hoop half-sheath, prevents the cable half-sheath from axially dislodging from the inner hoop half-sheath. The roller outer wall groove, positioned on the limiting boss, prevents the inner hoop half-sheath from axially dislodging from the entire outer housing, thereby preventing the wire from axially loosening in the cable hole. The two rows of rollers provide a longer wire clamping area, preventing the wire from bending in the clamping portion. The drainage holes allow for smooth drainage of rainwater that enters the wire clamp, preventing it from accumulating in the housing and freezing, which could affect the wire's rotation. Connecting the protruding ends of the spacer rods via pins at mounting holes one and two prevents the wire clamp from deflecting at a large angle relative to the main body of the spacer rod, which helps ensure the spacing between adjacent wires and prevents corona. By adding a water-blocking plate to the outer edge of the outer end face of the retaining flange, rainwater flowing along the axial direction of the conductor can be diverted to flow outward and downward, avoiding entering the inside of the wire clamp, thus avoiding accumulation inside the wire clamp and improving the freezing situation. By adding a vibrating assembly, the inner hoop half sleeve is driven to rotate during the rotation of the conductor, and the teeth move the vibrating assembly, causing vibrations to shake off the rainwater attached to the wire clamp, preventing the rainwater from adhering to the surface of the wire clamp and freezing. The spring drives the impact head to knock back the side wall to shake off the attached rainwater. The amplitude direction of the knocking vibration is perpendicular to the mounting hole, and a larger amplitude can be achieved by utilizing the pin gap, which has a better rainproof effect. By arranging multiple teeth evenly distributed on the outer wall of the inner hoop half sleeve, the knocking vibration can be continuously triggered during the rotation process, and it can also emit a warning sound to prevent birds from freezing.

[0040] Example 1

[0041] like Figures 1 to 10 As shown, the rotary wire clamp for the anti-dancing spacer rod of the present invention includes a main wire clamp housing 1, a wire clamp buckle cover housing 2, a locking pin 3, a roller 5 and a cable kit. The wire clamp buckle cover housing 2 and the main wire clamp housing 1 are both metal casting parts and are rotatably connected through the pin seat and the pin shaft at the top, that is, the wire clamp buckle cover housing 2 can be fastened to the semicircular opening of the main wire clamp housing 1 after rotation. A through hole for passing the locking pin 3 is provided at the bottom of the wire clamp buckle cover housing 2 and the top of the handle of the main wire clamp housing 1, that is, the locking pin 3 locks the wire clamp buckle cover housing 2 to the main wire clamp housing 1 to prevent the cable kit inside from falling off. A cable hole 10 for mounting the wire is provided in the middle of the cable kit, and a plurality of rollers 5 are provided on the inner walls of the main wire clamp housing 1 and the wire clamp buckle cover housing 2. The inner side of the roller 5 rolls and supports the outer wall of the cable kit.

[0042] By setting a main wire clamp shell 1 and a wire clamp buckle cover shell 2 connected by a pin shaft, the cable kit can be smoothly removed or installed after opening; the cable kit is supported by the roller 5, the rolling friction resistance is small, the wire rotation resistance is reduced, and the anti-dancing effect is good.

[0043] In a specific implementation of this embodiment, Figures 1 to 7 、 Figure 9 and Figure 10 As shown, the cable assembly comprises a cable half-sheath 6 and an inner hoop half-sheath 7, both of which have semicircular wall structures. The cable half-sheath 6 is made of rubber, and the two cable halves 6 are interlocked to form a central cable hole 10. The inner hoop half-sheath 7 is made of metal and is fastened to the outer sides of the two cable halves 6 by bolts. Obviously, the cable half-sheath 6 can also be directly bonded to the inner sidewalls of the inner hoop half-sheath 7 using weather-resistant adhesive. The outer wall of the inner hoop half-sheath 7 is supported by rollers 5 for rolling support.

[0044] Specifically, if Figure 10 As shown, a docking groove 702 is provided on one side of the folded edge of the end of the inner hoop half sleeve 7 and a docking plug 703 is provided on the other side. When the two inner hoop half sleeves 7 are buckled together, the docking plug 703 is just inserted into the docking groove 702 to form a positioning on the longitudinal section, avoiding the two inner hoop half sleeves 7 from being staggered, making it convenient to connect the bolts to lock the two inner hoop half sleeves 7.

[0045] By means of the split cable half sleeve 6 and the inner hoop half sleeve 7, the wire clamp can be flexibly installed at the position where the clamp is required; by the setting of the docking plug 703 and the docking groove 702, the inner hoop half sleeve 7 can be buckled and positioned for quick installation.

[0046] In a specific implementation of this embodiment, Figure 4 、 Figure 6 、 Figure 7 、 Figure 9 and Figure 10 As shown, the end face of the cable half-sheath 6 is provided with an outwardly extending rib 601, which is retained on the end face of the inner hoop half-sheath 7. That is, the inner side of the rib 601 contacts the outer end face of the inner hoop half-sheath 7. A limiting boss 704 is provided on the outer wall of the inner hoop half-sheath 7. The longitudinal cross-section of the roller 5 is I-shaped, and the limiting boss 704 is engaged in an annular groove on the outer wall of the roller 5.

[0047] Specifically, if Figures 4 to 8 and Figure 10 As shown, multiple rollers 5 are arranged in two rows along the axis of the cable hole 10. Within each row, the rollers 5 are evenly spaced along the circumference. In one embodiment, each row contains six rollers 5. The two coaxially arranged rollers 5 are mounted on the inner fold of the main cable clamp housing 1 or the cable clamp cover 2 via a centrally located roller shaft 4.

[0048] By limiting the retaining edge 601 on the end face of the inner hoop half sleeve 7, the cable half sleeve 6 is prevented from axially escaping from the inner hoop half sleeve 7. By the outer wall ring groove of the roller 5 riding on the limiting boss 704, the inner hoop half sleeve 7 can be prevented from axially escaping from the entire outer shell, thereby preventing the wire from axially loosening in the cable hole 10. By arranging two rows of rollers 5, a longer wire clamping area can be obtained, thereby preventing the wire from bending in the clamping part.

[0049] In a specific implementation of this embodiment, Figure 1 、 Figure 3 and Figure 6 As shown, a plurality of water leakage holes 8 are opened on the housing plate of the main wire clamp housing 1 or the wire clamp buckle cover housing 2. The water leakage holes 8 are long holes located outside the roller 5, and the number of the water leakage holes 8 and the roller 5 is the same.

[0050] By providing the water leakage hole 8, rainwater entering the interior of the wire clamp can be smoothly discharged, thereby preventing the water from accumulating in the housing and freezing, thereby affecting the rotation of the wire.

[0051] like Figure 1 、 Figure 2 、 Figure 5 and Figure 8 The handle end of the main line clamp housing 1 is provided with mounting hole 101 and mounting hole 2 102. Mounting hole 101 and mounting hole 2 102 are connected by a pin to the protruding end of the spacer rod. The side wall of the main line clamp housing 1 handle is also provided with a groove at the end surface of mounting hole 101, and the connection point of the spacer rod is provided with a corresponding boss.

[0052] Connecting the protruding ends of the spacer bars through two pins at the mounting hole 101 and the mounting hole 2 102 can prevent the wire clamp from deflecting at a large angle relative to the main body of the spacer bar, which is beneficial to ensuring the spacing between adjacent wires and preventing corona.

[0053] The installation process of the embodiment 1 of the rotary wire clamp for the anti-dancing spacer rod of the present invention is as follows: First, the wire clamp of the present application is installed on the protruding end of the spacer rod by installing pins through the installation hole 101 and the installation hole 2 102. When installing it on the conductor, it is necessary to first determine the clamping position of the conductor. The cable half sleeve 6 and the inner hoop half sleeve 7 are connected at the clamping position of the conductor. The two interlocking inner hoop half sleeves 7 are locked by the connecting bolts. At the same time, the cable half sleeve 6 is clamped to the conductor. The wire clamp cover shell 2 is opened relative to the main wire clamp housing 1. The semicircular opening of the main wire clamp housing 1 is aligned with the inner hoop half sleeve 7. Note that the annular groove of the roller 5 is mounted on the limiting boss 704. The wire clamp cover shell 2 is fastened and the locking pin 3 is used to lock the position, completing the installation of the wire clamp. The conductor is rotated by wind force, driving the cable half sleeve 6 and the inner hoop half sleeve 7 to rotate at the same angular velocity. The side wheel of the roller 5 rolls and supports the inner hoop half sleeve 7, reducing friction resistance.

[0054] Example 2

[0055] During actual use, the spacers are arranged in groups at intervals of about tens of meters on the line, and due to the influence of the spacers' own gravity, their position is slightly lower than other parts of the conductor. When it rains, rainwater falling on the conductor will flow along the axial direction of the conductor, and the lower-positioned wire clamps are often prone to rainwater collection. Even if rainwater is poured into the wire clamp, if it is not discharged in time with a leak hole 8, it will cause freezing in cold weather, affect the rotation of the wire, and reduce the anti-dancing performance. Therefore, it is necessary to improve the rainproof performance of the wire clamp, and improvements are made on the basis of the above-mentioned embodiment 1 to form this embodiment.

[0056] like Figures 11-13 As shown, the outer edge of the retaining flange 601 is integrally provided with a water-blocking disc 602, also made of rubber. Water-blocking disc 602 is tilted outward, and its outer diameter is larger than the diameter of the inner folded edges of the main cable clamp housing 1 and the cable clamp buckle cover 2. Two semicircular water-blocking discs 602 are joined to form a single, outward-facing, flared structure.

[0057] By adding a water blocking plate 602 on the outer edge of the outer end surface of the retaining edge 601, rainwater flowing along the axial direction of the conductor can be diverted and directed outward and downward to avoid entering the interior of the wire clamp, thereby avoiding accumulation inside the wire clamp and improving the freezing situation.

[0058] In a specific implementation of this embodiment, Figure 14 and Figure 15As shown, the rotary clamp for anti-dancing spacers of the present invention also includes a vibrator assembly 9. A shifting tooth 705 is provided in the middle of the outer wall of the inner hoop half 7. The shifting tooth 705 is integrally formed on the outer wall of the inner hoop half 7. Two vibrator assemblies 9 are provided, one each on the inner folded edge between the main clamp housing 1 and the clamp buckle cover 2. Specifically, the vibrator assembly 9 is provided on the inner folded edge between the two rows of rollers 5. The working end of the vibrator assembly 9 can be shifted and vibrated by the shifting tooth 705.

[0059] Specifically, if Figure 14 and Figure 15 As shown, the vibration starting assembly 9 includes a mounting seat 901, a spring 902 and a striking head 903. A vibration component mounting hole 105 is radially opened on the inner folding edge of the main line clamp housing 1. The mounting seat 901 is fixedly connected to the outer end of the vibration component mounting hole 105. The mounting seat 901 can be connected by a threaded connection or an interference fit embedded connection. The outer end of the spring 902 is welded to the inner side surface of the mounting seat 901, and the inner end of the spring 902 is welded to the striking head 903. The striking head 903 can contact the shifting tooth 705, and the striking head 903 is spherical.

[0060] Specifically, if Figure 14 and Figure 15 As shown, there are multiple shifting teeth 705 and they are evenly distributed along the circumference of the outer wall of the inner hoop half sleeve 7. The inner end of the vibration member mounting hole 105 facing the cable hole 10 is configured as a half-bell mouth. It should be noted that the skirt edges of the half-bell mouths of the two vibration assemblies 9 face opposite directions, that is, one vibration assemblies 9 works when the shifting teeth 705 rotates clockwise, and the other works when the shifting teeth 705 rotates counterclockwise. When the vibration assemblies 9 do not work, the impact head 903 is pushed back a certain distance by the shifting teeth 705.

[0061] By adding a vibration-starting assembly 9, the inner hoop half 7 is driven to rotate during the wire rotation process. The shifting teeth 705 shift the vibration-starting assembly 9, causing the vibration to shake off rainwater adhering to the wire clamp, preventing the rainwater from adhering to the wire clamp surface and freezing. The spring 902 drives the impact head 903 to knock back the vibration on the side wall to shake off the adhering rainwater. The amplitude direction of the knocking vibration is perpendicular to the mounting hole 101. The pin gap can achieve a larger amplitude, which has a better rainproof effect. By arranging multiple shifting teeth 705 evenly distributed on the outer wall of the inner hoop half 7, the knocking vibration can be continuously triggered during the rotation process, and it can also play the role of emitting a warning sound to prevent birds from freezing.

[0062] The working principle of the second embodiment of the rotary wire clamp with anti-dancing spacers of the present invention is as follows: During rainy or sleety weather, rainwater flowing along the conductor axis to the sides of the wire clamp is blocked by the water-blocking disk 602, causing the rainwater to flow outward and downward, avoiding entry into the clamp. This prevents accumulation inside the clamp and improves freezing conditions. During the wire rotation process, the inner hoop half 7 drives the shifting teeth 705 to rotate, which in turn shifts the impact head 903, which strikes the side wall of the vibrator mounting hole 105, causing vibration. This vibration helps the wire clamp quickly shake off attached rainwater or snow.

[0063] In summary, the rotary wire clamp for the anti-dancing spacer rod of the present invention, by providing a main wire clamp housing 1 and a wire clamp buckle cover housing 2 connected by a pin shaft, can smoothly remove or install the cable kit after opening; the cable kit is supported by the roller 5, which has low rolling friction resistance, reduces the rotational resistance of the wire, and has a good anti-dancing effect. In addition, the split cable half sleeve 6 and the inner hoop half sleeve 7 can flexibly be installed at the required location; the inner hoop half sleeve 7 can be positioned by buckling through the provision of the docking plug 703 and the docking groove 702, facilitating quick installation. By limiting the edge 601 on the end face of the inner hoop half sleeve 7, the cable half sleeve 6 is prevented from axially dislodging from the inner hoop half sleeve 7. By having the outer wall ring groove of the roller 5 riding on the limiting boss 704, the inner hoop half sleeve 7 can be prevented from axially dislodging from the entire outer shell, thereby preventing the wire from axially loosening in the cable hole 10. By setting two rows of rollers 5, a longer wire clamping area can be obtained, preventing the wire from bending in the clamping part. By setting the leakage hole 8, rainwater entering the interior of the wire clamp can be smoothly discharged, avoiding ice after accumulation in the shell and affecting the rotation of the wire. By connecting the protruding end of the spacer rod with two pins at the mounting hole 101 and the mounting hole 2 102, the wire clamp can be prevented from deflecting at a large angle relative to the main part of the spacer rod, which is beneficial to ensure the spacing between adjacent wires and prevent corona. By adding a water-blocking plate 602 to the outer edge of the outer end face of the retaining edge 601, rainwater flowing along the axial direction of the conductor can be diverted and directed outward and downward to avoid entering the interior of the wire clamp, thereby avoiding accumulation inside the wire clamp and improving the freezing situation. By adding a vibration component 9, the inner hoop half sleeve 7 is driven to rotate during the rotation of the conductor, and the shifting teeth 705 shift the vibration component 9, causing the vibration to shake off the rainwater attached to the wire clamp, preventing the rainwater from adhering to the surface of the wire clamp and freezing. The spring 902 drives the impact head 903 to knock back the side wall to shake off the attached rainwater. The amplitude direction of the knocking vibration is perpendicular to the mounting hole 101, and a larger amplitude can be achieved by utilizing the pin-jointed gap, which has a better rainproof effect. By arranging multiple shifting teeth 705 evenly distributed on the outer wall of the inner hoop half sleeve 7, the knocking vibration can be continuously triggered during the rotation process, and a "da da da" warning sound can be emitted at ordinary times to prevent birds.
