Description

Technical Field

[0001] This invention belongs to the technical field of conductor spacing equipment, and specifically relates to a conductor spacing isolation device for fixed poles. Background Technology

[0002] In overhead power and telecommunications line projects, a certain safety distance must be maintained between multiple circuits erected on the same pole or between different phase conductors of the same circuit to prevent conductors from approaching each other due to wind swaying, galloping, or other reasons, which could lead to serious accidents such as short circuits and discharges. Furthermore, when erecting or replacing poles while they are energized, a certain distance must also be maintained between the phase conductors to ensure the safe and stable operation of the power grid. To achieve these objectives, conductor spacers or spacer devices are widely used between poles to fix and separate the conductors.

[0003] Many existing conductor bay devices use bolts for direct fastening or enclosed clamps, requiring complete loosening of bolts or disassembly of multiple components during installation and subsequent maintenance. This is cumbersome, time-consuming, and labor-intensive. Furthermore, the length of existing conductor bay devices is often fixed, or the adjustment range is limited and the adjustment method is complex. This results in poor adaptability of the device to different tower structures and conductor spacing requirements, necessitating the stocking of spare parts in various specifications. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a conductor spacing isolation device for fixed poles.

[0005] The objective of this invention is achieved as follows: a conductor spacing isolation device for fixing a utility pole, comprising: a main clamp: the main clamp has an open slot inside, an open ring is movably disposed inside the open slot, a toothed ring is disposed outside the open ring, a drive head is disposed on the upper side of the main clamp, a drive gear is fixedly disposed inside the drive head, a driven gear is meshed outside the drive gear, and the driven gear meshes with the toothed ring. Secondary cable clamp: A fixing part is fixedly provided at the end of the secondary cable clamp away from the main cable clamp, and a moving part is movably provided on the outside of the secondary cable clamp; a clamping mechanism is provided inside the secondary cable clamp; Connecting rod: The connecting rod includes an outer cylinder and an inner rod. The end of the outer cylinder is fixedly connected to the main wire clamp, and the end of the inner rod is fixedly connected to the secondary wire clamp.

[0006] A limiting groove is provided on the inner side of the opening groove, and a limiting strip is provided on the outer side of the opening ring. The limiting strip and the limiting groove are engaged with each other.

[0007] The inner rod is inserted into the outer cylinder, and the inner rod and the outer cylinder are connected by threads. The length of the inner rod inside the outer cylinder can be adjusted by rotating the inner rod.

[0008] The main clamp is equipped with a closing mechanism, which includes a closing screw. Sleeves are symmetrically screwed onto the outer sides of the closing screw, and clamping plates are fixedly mounted on the outer sides of both sleeves. The closing mechanism can further clamp and position the wires inside the main clamp.

[0009] The clamping mechanism includes a square rod, which is fixedly disposed on the outside of the fixed part, and the moving part is engaged inside the square rod.

[0010] The square rod has a movable translation block inside, and a first hollow surface on the side of the square rod. The moving part passes through the first hollow surface and is fixedly connected to the translation block. The front of the square rod has a second hollow surface, and a translation screw passes through the second hollow surface of the translation block. A butterfly nut is screwed onto the outside of the translation screw.

[0011] A pad is provided on the inner side of the moving part, and a telescopic spring is provided between the pad and the moving part. The pad and the telescopic spring can elastically clamp the wires inside the secondary clamp.

[0012] Both the fixing part and the pad are arc-shaped. The arc shape makes it easier to fit with the wire.

[0013] A rotating mechanism is provided between the two main clamps. The rotating mechanism includes a protrusion and a recess. The recess is fixedly disposed on the side of the main clamp, and the positions of the protrusion and the recess are correspondingly engaged.

[0014] The protrusion includes a support plate, and a blocking plate is provided on the top of the support plate.

[0015] The beneficial effects of this invention are: The main clamp has an internal slot with a movable open ring. The toothed ring on the outside of the open ring engages with the drive gear and driven gear inside the drive head. This design allows for precise control of the opening and closing of the open ring via the drive head, enabling flexible fixing or loosening of the wire and improving installation and disassembly efficiency.

[0016] The distance between the main clamp and the secondary clamp can be adjusted according to the actual installation situation by using the inner rod and the outer cylinder, so that the device can adapt to the needs of fixing wires with different spacing.

[0017] The square rod is fixed to the outside of the fixed part, and the moving part is snapped into the inside of the square rod. The translation block inside the square rod is connected to the moving part through the first hollow surface, and the translation screw passes through the second hollow surface and is connected to the translation block. The butterfly nut is screwed onto the translation screw. This structure allows the translation block to move the moving part along the square rod by rotating the butterfly nut, flexibly adjusting the clamping range to accommodate wires of different sizes.

[0018] A rotating mechanism is installed between the two main clamps. The recessed part is fixed to the side of the main clamp, and the protruding part engages with the recessed part. This structure allows the two main clamps to rotate relative to each other within a certain angle range. It is used for the most common three-phase conductor structure on utility poles and can flexibly adjust the angle according to the direction and layout of the three-phase conductors, improving the flexibility and convenience of installation.

[0028] The present invention will now be further described with reference to the accompanying drawings. Example 1

[0029] like Figure 1-3 As shown, a conductor spacing isolation device for fixing a utility pole includes: Main clamp 1: The main clamp 1 has an opening groove 4 inside, an opening ring 6 is movably arranged inside the opening groove 4, a toothed ring 8 is arranged outside the opening ring 6, a drive head 9 is arranged on the upper side of the main clamp 1, a drive gear 10 is fixedly arranged inside the drive head 9, a driven gear 11 is meshed on the outside of the drive gear 10, and the driven gear 11 meshes with the toothed ring 8. Secondary clamp 2: A fixing part 12 is fixedly provided at one end of the secondary clamp 2 away from the main clamp 1, and a moving part 13 is movably provided on the outside of the secondary clamp 2; a clamping mechanism is provided inside the secondary clamp 2. Connecting rod 3: The connecting rod 3 includes an outer cylinder 14 and an inner rod 15. The end of the outer cylinder 14 is fixedly connected to the main wire clamp 1, and the end of the inner rod 15 is fixedly connected to the secondary wire clamp 2.

[0030] For better performance, a limiting groove 5 is provided on the inner side of the opening groove 4, and a limiting strip 7 is provided on the outer side of the opening ring 6. The limiting groove 5 on the inner side of the opening groove 4 and the limiting strip 7 on the outer side of the opening ring 6 cooperate to prevent the opening ring 6 from shifting during rotation and ensure the stable operation of the opening ring 6.

[0031] For better results, the inner rod 15 is inserted into the outer cylinder 14, and the inner rod 15 and the outer cylinder 14 are connected by threads.

[0032] For better performance, the main clamp 1 is equipped with a closing mechanism 28. The closing mechanism 28 includes a closing screw 29, with sleeves 30 symmetrically screwed onto the outer sides of the closing screw 29. Clamping pieces 31 are fixedly mounted on the outer sides of both sleeves 30. By rotating the closing screw 29, the two sleeves 30 can drive the clamping pieces 31 to move relative to each other, achieving stable clamping of wires of different thicknesses and enhancing the device's adaptability to different wire specifications. Furthermore, the position of the closing mechanism 28 does not interfere with the position of the open ring 6.

[0033] In use, the main clamp 1 of the device is fitted onto the predetermined installation position of the power pole conductor. A tool is inserted into the drive head 9 of the main clamp 1, and the drive head 9 is rotated. The drive gear 10 inside the drive head 9 rotates accordingly, thereby driving the driven gear 11, which meshes with it, to rotate. Since the driven gear 11 meshes with the toothed ring 8 on the outer side of the open ring 6, the driven gear 11 drives the toothed ring 8 to rotate, causing the open ring 6 to move within the opening groove 4, thus opening the open ring 6. The main conductor is then placed into the space formed after the open ring 6 is opened, ensuring that the main conductor is in the correct position. If further reinforcement of the main conductor is required, the closing mechanism 28 inside the main clamp 1 can be used.

[0034] Adjust the length of connecting rod 3 according to the spacing requirements between the main conductor and the secondary conductor during actual installation. Rotate the inner rod 15 or the outer cylinder 14. Due to the thread, the inner rod 15 will extend or retract relative to the outer cylinder 14, thereby adjusting the overall length of connecting rod 3 so that the distance between the secondary clamp 2 and the main clamp 1 meets the installation requirements. Place the secondary conductor between the fixed part 12 and the moving part 13 of the secondary clamp. Adjust the position of the moving part 13 according to the thickness of the secondary conductor. Move the moving part 13 closer to the fixed part 12 to clamp the secondary conductor tightly. Example 2

[0035] like Figure 1-4 As shown, a conductor spacing isolation device for fixing a utility pole includes: Main clamp 1: The main clamp 1 has an opening groove 4 inside, an opening ring 6 is movably arranged inside the opening groove 4, a toothed ring 8 is arranged outside the opening ring 6, a drive head 9 is arranged on the upper side of the main clamp 1, a drive gear 10 is fixedly arranged inside the drive head 9, a driven gear 11 is meshed on the outside of the drive gear 10, and the driven gear 11 meshes with the toothed ring 8. Secondary clamp 2: A fixing part 12 is fixedly provided at one end of the secondary clamp 2 away from the main clamp 1, and a moving part 13 is movably provided on the outside of the secondary clamp 2; a clamping mechanism is provided inside the secondary clamp 2. Connecting rod 3: The connecting rod 3 includes an outer cylinder 14 and an inner rod 15. The end of the outer cylinder 14 is fixedly connected to the main wire clamp 1, and the end of the inner rod 15 is fixedly connected to the secondary wire clamp 2.

[0036] For better performance, a limiting groove 5 is provided on the inner side of the opening groove 4, and a limiting strip 7 is provided on the outer side of the opening ring 6. The limiting groove 5 on the inner side of the opening groove 4 and the limiting strip 7 on the outer side of the opening ring 6 cooperate to prevent the opening ring 6 from shifting during rotation and ensure the stable operation of the opening ring 6.

[0037] For better results, the inner rod 15 is inserted into the outer cylinder 14, and the inner rod 15 and the outer cylinder 14 are connected by threads.

[0038] For better performance, the main clamp 1 is equipped with a closing mechanism 28. The closing mechanism 28 includes a closing screw 29, with sleeves 30 symmetrically screwed onto the outer sides of the closing screw 29. Clamping pieces 31 are fixedly mounted on the outer sides of both sleeves 30. By rotating the closing screw 29, the two sleeves 30 can drive the clamping pieces 31 to move relative to each other, achieving stable clamping of wires of different thicknesses and enhancing the device's adaptability to different wire specifications. Furthermore, the position of the closing mechanism 28 does not interfere with the position of the open ring 6.

[0039] For better results, the clamping mechanism includes a square rod 16, which is fixedly disposed on the outside of the fixed part 12, and the moving part 13 is engaged inside the square rod 16.

[0040] For better results, a translation block 19 is movably arranged inside the square rod 16, and a first hollow surface 17 is provided on the side of the square rod 16. The moving part 13 passes through the first hollow surface 17 and is fixedly connected to the translation block 19. A second hollow surface 18 is provided on the front of the square rod 16, and a translation screw 20 is provided through the second hollow surface 18 of the translation block 19. A butterfly nut 21 is screwed onto the outside of the translation screw 20.

[0041] For better performance, a pad 22 is provided on the inner side of the moving part 13, and a telescopic spring 23 is provided between the pad 22 and the moving part 13. The telescopic spring 23 can compensate for minor dimensional changes in the wire caused by thermal expansion and contraction or vibration, effectively prevent the wire from loosening, absorb some vibration energy, and protect the wire insulation layer.

[0042] For better results, both the fixing part 12 and the pad 22 are arc-shaped. The arc-shaped fixing part 12 and the pad 22 fit the shape of the wire better, providing uniform contact pressure.

[0043] In another embodiment, the internal clamping mechanism of the secondary wire clamp 2 preferably uses the following method: The butterfly nut 21 is rotated counter-rotated using the hand or a suitable tool, causing the butterfly nut 21 to move outward along the translation screw 20, thereby releasing the fixing effect on the translation block 19. The moving part 13 is gently pushed by hand to move the translation block 19 within the square rod 16. The moving part 13 is moved to a suitable position so that the distance between the fixed part 12 and the moving part 13 is slightly larger than the diameter of the secondary wire, leaving space for placing the secondary wire. The secondary wire is placed between the fixed part 12 and the moving part 13 of the secondary wire clamp 2, and the moving part 13 is pushed to contact the secondary wire. The secondary wire makes full contact with both the fixed part 12 and the moving part 13 to ensure clamping stability. Rotate the butterfly nut 21 in the opposite direction again by hand or with a tool, so that the butterfly nut 21 moves inward along the translation screw 20. When the butterfly nut 21 comes into contact with the square rod 16 and generates a certain pressure, the pressure will be transmitted to the translation block 19 through the translation screw 20, thereby fixing the position of the translation block 19 in the square rod 16, and thus fixing the position of the moving part 13. Example 3

[0044] like Figure 1-8 As shown, a conductor spacing isolation device for fixing a utility pole includes: Main clamp 1: The main clamp 1 has an opening groove 4 inside, an opening ring 6 is movably arranged inside the opening groove 4, a toothed ring 8 is arranged outside the opening ring 6, a drive head 9 is arranged on the upper side of the main clamp 1, a drive gear 10 is fixedly arranged inside the drive head 9, a driven gear 11 is meshed on the outside of the drive gear 10, and the driven gear 11 meshes with the toothed ring 8. Secondary clamp 2: A fixing part 12 is fixedly provided at one end of the secondary clamp 2 away from the main clamp 1, and a moving part 13 is movably provided on the outside of the secondary clamp 2; a clamping mechanism is provided inside the secondary clamp 2. Connecting rod 3: The connecting rod 3 includes an outer cylinder 14 and an inner rod 15. The end of the outer cylinder 14 is fixedly connected to the main wire clamp 1, and the end of the inner rod 15 is fixedly connected to the secondary wire clamp 2.

[0045] For better performance, a limiting groove 5 is provided on the inner side of the opening groove 4, and a limiting strip 7 is provided on the outer side of the opening ring 6. The limiting groove 5 on the inner side of the opening groove 4 and the limiting strip 7 on the outer side of the opening ring 6 cooperate to prevent the opening ring 6 from shifting during rotation and ensure the stable operation of the opening ring 6.

[0046] For better results, the inner rod 15 is inserted into the outer cylinder 14, and the inner rod 15 and the outer cylinder 14 are connected by threads.

[0047] For better performance, the main clamp 1 is equipped with a closing mechanism 28. The closing mechanism 28 includes a closing screw 29, with sleeves 30 symmetrically screwed onto the outer sides of the closing screw 29. Clamping pieces 31 are fixedly mounted on the outer sides of both sleeves 30. By rotating the closing screw 29, the two sleeves 30 can drive the clamping pieces 31 to move relative to each other, achieving stable clamping of wires of different thicknesses and enhancing the device's adaptability to different wire specifications. Furthermore, the position of the closing mechanism 28 does not interfere with the position of the open ring 6.

[0048] For better results, the clamping mechanism includes a square rod 16, which is fixedly disposed on the outside of the fixed part 12, and the moving part 13 is engaged inside the square rod 16.

[0049] For better results, a translation block 19 is movably arranged inside the square rod 16, and a first hollow surface 17 is provided on the side of the square rod 16. The moving part 13 passes through the first hollow surface 17 and is fixedly connected to the translation block 19. A second hollow surface 18 is provided on the front of the square rod 16, and a translation screw 20 is provided through the second hollow surface 18 of the translation block 19. A butterfly nut 21 is screwed onto the outside of the translation screw 20.

[0050] For better performance, a pad 22 is provided on the inner side of the moving part 13, and a telescopic spring 23 is provided between the pad 22 and the moving part 13. The telescopic spring 23 can compensate for minor dimensional changes in the wire caused by thermal expansion and contraction or vibration, effectively prevent the wire from loosening, absorb some vibration energy, and protect the wire insulation layer.

[0051] For better results, both the fixing part 12 and the pad 22 are arc-shaped. The arc-shaped fixing part 12 and the pad 22 fit the shape of the wire better, providing uniform contact pressure.

[0052] For better performance, a rotating mechanism is provided between the two main clamps 1. The rotating mechanism includes a protrusion 24 and a recess 25. The recess 25 is fixedly disposed on the side of the main clamp 1, and the positions of the protrusion 24 and the recess 25 are correspondingly engaged. The protrusion 24 and the recess 25 allow relative rotation between the two main clamps 1, thereby adapting to complex working conditions where the conductors are not arranged in parallel.

[0053] For better performance, the protrusion 24 includes a support plate 26, and a blocking piece 27 is provided on the top of the support plate 26. The blocking piece 27 can prevent accidental disengagement when the two main cable clamps 1 are rotated to a specific angle, thus playing a role in axial limiting and preventing loosening.

[0054] In another embodiment, during the most common pole-mounted three-phase conductor spacing isolation process, two sets of devices can be combined by a rotating mechanism to facilitate good isolation of the three-phase conductors.

[0055] The protrusion 24 on the side of the main clamp 1 engages with the recess 25 on the side of another main clamp 1. The protrusion 24 includes a support plate 26 and a stopper 27 on the top of the support plate 26, while the recess 25 is a groove structure fixed to the side of the main clamp 1. Since the protrusion 24 and the recess 25 are designed to correspond to each other, they can form a relatively stable connection structure after engagement. However, the two main clamps 1 can still rotate around the center of the rotating mechanism at a certain angle. After installing the two main clamps 1 on the main line, the appropriate angle to which the two main clamps 1 need to be adjusted is determined according to the actual route and layout requirements of the other conductors on the pole. Due to the existence of the rotating mechanism, the two main clamps 1 can rotate relative to each other around the engagement center of the protrusion 24 and the recess 25 to adjust the position of the two secondary clamps 2. Then, the two secondary clamps 2 are fixed to the outside of different secondary conductors on both sides of the main clamp 1, thus completing the interval isolation and fixing of the three-phase conductors on the pole.
