Abstract
Description
Technical Field
[0001] This invention relates to the field of power tool technology, and more specifically to a manhole telescopic clamp. Background Art
[0002] With economic development, the demand for electricity in industrialized regions is increasing. To meet the requirements of large-scale power transmission, power transmission lines have adopted tubular busbars capable of carrying high currents. The corona effect is a persistent problem in power transmission. Under certain meteorological conditions, voltage, phase-to-phase distance, and layout, the corona critical voltage is mainly affected by the conductor radius and surface roughness coefficient; that is, the larger the conductor radius and the smoother the surface, the smaller the corona effect. Therefore, using large-diameter aluminum alloy tubular busbars is an effective measure to reduce corona radio interference levels.
[0003] To achieve remote transmission, multiple busbars need to be connected, and the jumpers at the busbar connections generally use telescopic flexible connectors. These connectors consist of two busbar clamps connected by 6-8 small-section steel core stranded wires to reduce weight and ensure a continuous and uniform distribution of the electromagnetic field, preventing electromagnetic distortion. Currently, the multiple steel / aluminum core stranded wires of the busbar clamps are arranged parallel and equidistantly. The two outer stranded wires tend to overheat during use. Over long-term use, uneven temperature distribution within the clamp body can lead to changes in mechanical properties, reducing its lifespan. In severe cases, sudden breakage can cause power outages. Furthermore, existing busbar clamps cannot meet the long-stroke sliding requirements of busbars under the prolonged high-temperature and low-temperature conditions of substations, and the connection stability cannot be guaranteed during these processes.
[0004] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a tube-mounted telescopic clamp, application number 200710019842.1, which comprises a pair of bodies with tube grooves, a cover plate connected to the bodies, and several elastic strands connected to the bodies. The elastic strands between the bodies are arranged in an arc shape along the axial section of the bodies, and the several elastic strands are arranged in a fan shape on the radial section of the bodies. The distance between the core of each strand and the axis of the tube groove of the body is equal.
[0005] The above solution has solved the problem to some extent that the outer stranded wire of the busbar clamp is prone to overheating and affecting its mechanical properties in the existing technology. However, the solution still has many shortcomings. For example, it is difficult to meet the long-stroke sliding requirements of the busbar when it is thermally expanded and contracted in a high temperature difference environment, and the connection stability of the busbar cannot be guaranteed during the thermal expansion and contraction process. Summary of the Invention

Both ends of the sliding rotation positioning pin are located on the outer wall of the main body of the diversion plate and are locked by pins.
[0012] In the aforementioned type of manhole telescopic clamp, the support assembly includes a strip-shaped lifting adjustment hole longitudinally disposed on the main body of the diversion plate. A lifting slide rod is disposed in the strip-shaped lifting adjustment hole, and a telescopic connecting rod is rotatably disposed at one end of the lifting slide rod located on the inner wall of the main body of the diversion plate. The end of the telescopic connecting rod away from the lifting slide rod is rotatably connected to a rotating connecting seat disposed at the bottom of the sliding rotating connecting rod.

Detailed Implementation
[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0028] like Figure 1-8As shown, a telescopic cable clamp includes a cable clamp body 1, a cable clamp cover plate 2 connected to the lower end of the cable clamp body 1, and a clamping cavity formed between the cable clamp cover plate 2 and the inner circumferential side of the cable clamp body 1. A sliding rotating rod assembly 3 is connected to one end of the cable clamp body 1. A flow guide plate structure 4 is provided at the end of the sliding rotating rod assembly 3 away from the cable clamp body 1. The outer walls on both sides of the flow guide plate structure 4 are connected to the bottom of the sliding rotating rod assembly 3 through a support assembly 5 and provide support for the sliding rotating rod assembly 3. A pin connection structure 6 for sliding positioning of the sliding rotating rod assembly 3 is provided on the flow guide plate structure 4. An aluminum wire 7 is provided at the upper end of the flow guide plate structure 4. The end of the aluminum wire 7 away from the flow guide plate structure 4 is inserted into the cable clamp body 1. An elastic positioning mechanism 8 for the wire is provided on the upper surface of the cable clamp body 1.
[0029] The clamp body 1 and the clamp cover plate 2 are symmetrically arranged in an arc shape. The clamp body 1 has upper connecting seats 11 on both sides, and several locking screws 12 are provided on the upper connecting seats 11. The clamp cover plate 2 has lower connecting seats 21 on both sides, and several threaded locking holes 22 are provided on the lower connecting seats 21, which correspond one-to-one with the locking screws 12. The clamp cover plate 2 has a top pressure groove 23 on its circumferential inner wall, and an elastic compression rubber pad 24 extending along the circumferential inner wall of the clamp cover plate 2 is connected to the top pressure groove 23 by a top pressure spring.
[0030] The clamping cavity is used to fix the busbar, and the aluminum conductor 7 passes through the conductor positioning through hole 14 and is connected to the busbar.
[0031] The top pressure spring drives the elastic compression rubber pad 24 elastic top pressure tube busbar to maintain stable clamping during thermal expansion and contraction, preventing loosening and thus improving connection stability.
[0032] As can be seen, the sliding rotating rod assembly 3 includes a sliding rotating connecting rod 31. One end of the sliding rotating connecting rod 31 is provided with a connecting plate frame 32, and the connecting plate frame 32 is circumferentially connected to the connecting tail 34 at one end of the wire clamp body 1 by a number of connecting bolts 33. The connecting tail 34 is provided with a plug-in connecting hole 35 at its axial center, and the connecting plate frame 32 is provided with a positioning plug 36 corresponding to the plug-in connecting hole 35 at its axial center. The other end of the sliding rotating connecting rod 31 is provided with a strip-shaped sliding stroke hole 37.
[0033] When the tube busbar, which is positioned at one end in the clamping cavity, expands and contracts due to heat, its length changes. This causes the sliding rotation positioning pin 61 to slide in the strip-shaped sliding through hole 62, achieving initial stroke adjustment. Secondly, when the sliding rotation positioning pin 61 slides to its maximum stroke in the strip-shaped sliding through hole 62, the sliding rotation connecting rod 31 continues to slide along the sliding rotation positioning pin 61, achieving secondary stroke adjustment. This effectively increases the redundancy formed by sliding and improves the sliding range.
[0034] Obviously, the drainage plate structure 4 includes a drainage plate body 41 arranged symmetrically. The inner wall of the drainage plate body 41 is provided with a wire guide seat 42 through a telescopic adjustment seat. The wire guide seat 42 is provided with a plurality of wire holes 43. The wire guide seats 42 located on the two drainage plate bodies 41 are staggered and the wire holes 43 on the two wire guide seats 42 correspond one to one.
[0035] The staggered position of the wire guide seat 42 can be moved by the telescopic adjustment seat, thereby changing the intersection range of the corresponding wire guide holes 43 on the two wire guide seats 42, thus achieving the clamping of the aluminum wire 7.
[0036] Furthermore, the pin connection structure 6 includes a sliding rotation positioning pin 61, which is slidably disposed in the strip-shaped sliding through hole 62 on the main body 41 of the diversion plate. The sliding rotation positioning pin 61 passes through the strip-shaped sliding stroke hole 37 at one end of the sliding rotation connecting rod 31 to form a sliding rotation positioning of the sliding rotation connecting rod 31. Both ends of the sliding rotation positioning pin 61 are located on the outer wall of the main body 41 of the diversion plate and are locked by pins.
[0037] Specifically, the support component 5 includes a strip-shaped lifting adjustment hole 51 longitudinally arranged on the diversion plate body 41. A lifting slide rod 52 is provided in the strip-shaped lifting adjustment hole 51, and a telescopic connecting rod 53 is rotatably provided at one end of the lifting slide rod 52 located on the inner wall of the diversion plate body 41. The end of the telescopic connecting rod 53 away from the lifting slide rod 52 is rotatably connected to a rotating connecting seat 54 provided at the bottom of the sliding rotating connecting rod 31. A position adjustment groove 55 is provided at the bottom of the sliding rotating connecting rod 31 for the rotating connecting seat 54 to slide.
[0038] The lifting slide bar 52 can slide up and down within the strip-shaped lifting adjustment hole 51 to adapt to the rotation angle adjustment requirements of the sliding rotation rod assembly 3. The telescopic connecting rod 53 provides flexible support adjustment according to the sliding of the sliding rotation connecting rod 31, better supporting the sliding rotation connecting rod 31. The locking shaft 57 in the locking holes 56 on both sides of the strip-shaped lifting adjustment hole 51 on the main body of the diversion plate 41 is connected by the synchronous connecting rod 58 to achieve synchronous movement. The locking shaft 57 is connected to the lifting slide bar 52 through the positioning support rod 59. When the lifting slide bar 52 is adjusted to a suitable position, it can be fixed by the locking shaft 57 to ensure the stability of the support.
[0039] Furthermore, the main body 41 of the diversion plate is provided with vertically arranged locking holes 56 on both sides of the strip-shaped lifting adjustment hole 51. Locking shafts 57 are provided in the locking holes 56, and the locking shafts 57 in the two locking holes 56 are connected by a synchronous connecting rod 58. The locking shafts 57 are connected to the lifting slide rod 52 through a positioning support rod 59.
[0040] More specifically, the wire elastic positioning mechanism 8 includes a damping rotating shaft 81 disposed at one end of the wire clamp body 1. Both ends of the damping rotating shaft 81 are connected to arc-shaped flexible support seats 83 via support plate frames 82. The aluminum wire 7 is positioned on the flexible support seats 83 by a number of adjustable plug-in rings 84.
[0041] The adjustable plug ring 84 positions the aluminum wire 7, and the damping rotation shaft 81 can be adjusted according to the bending angle of the aluminum wire 7 to ensure a close fit support.
[0042] In detail, the upper end face of the clamp body 1 is provided with a support positioning seat 9, a flexible ball 91 is positioned inside the support positioning seat 9, an arc-shaped positioning seat 92 is connected to the upper end face of the flexible ball 91, the upper end face of the arc-shaped positioning seat 92 has a positioning groove 93 for positioning the aluminum wire 7, the aluminum wire 7 is embedded in the positioning groove 93, and limit frame plates 94 are provided at both ends of the arc-shaped positioning seat 92.
[0043] The flexible ball 91 inside the positioning seat 9 on the upper end face of the clamp body 1 can rotate flexibly, driving the arc-shaped positioning seat 92 to adjust the angle. The positioning groove 93 on the upper end face of the arc-shaped positioning seat 92 positions the aluminum wire 7, and the limiting frame plates 94 at both ends prevent the aluminum wire 7 from falling off, further ensuring the connection stability of the aluminum wire 7 during the thermal expansion and contraction process of the busbar.
[0044] Preferably, a guide positioning ring 13 is provided at one end of the wire clamp body 1. The guide positioning ring 13 is circumferentially arranged with a plurality of wire positioning through holes 14. The aluminum wire 7 passes through the wire positioning through holes 14 and extends toward the clamping cavity.
[0045] In summary, the principle of this embodiment is as follows: the busbar is clamped and fixed by the arc-shaped clamping of the clamp body 1 and the clamp cover plate 2 and the elastic pressing of the elastic pressing rubber pad 24. The sliding rotating rod assembly 3, together with the pin connection structure 6, realizes long-stroke sliding and rotation as well as sliding stroke redundancy. Secondly, the support assembly 5 realizes stable support for the sliding rotating connecting rod 31 during the sliding and angle adjustment process. The aluminum wire 7 is connected by the diversion plate structure 4 and is positioned by multiple mechanisms such as the wire elastic positioning mechanism 8 to ensure smooth sliding and stable connection when the busbar expands and contracts with heat.
