Description

Technical Field

[0001] The invention relates to the technical field of power lines, in particular to a high-voltage connection fitting for power lines. Background Art

[0002] Power line joint fittings are an indispensable and important part of the power system. They are mainly used for the connection of overhead power line conductors and lightning protection wire terminals, the connection of non-linear pole tower jumpers and conductor repairs. These fittings undertake the key tasks of transmitting mechanical loads, electrical loads and certain protective functions during the power transmission process, and are of great significance to ensuring the safe and stable operation of the power system.

[0003] In the prior art, there is a graphite grounding wire connection hardware with publication number CN109494491A, which is composed of an upper splint, a fastening assembly, a lower splint, and a pad; the upper splint is connected to the lower splint through the fastening assembly; the pad is fixed on the large arc-shaped structural surface of the clamping groove I of the upper splint and the clamping groove II of the lower splint; since the exits at both ends of the clamping groove I and the clamping groove II are both large arc-shaped structures, it is ensured that the graphite grounding wire is not broken during the transition; since the pad is fixed on the large arc-shaped structural surface of the clamping groove I of the upper splint and the clamping groove II of the lower splint, the wear of the graphite grounding wire is avoided; since the clamping groove I on the upper splint adopts a straight or curved structure, multiple graphite grounding wires can be selected and fixed according to specific needs; due to the reasonable structure and convenient operation, it has great practical and promotion value.

[0004] However, in actual use, during power construction, the screw and the nut are easily loosened due to external force vibration. Once the nut is loose, the line will cause creep, and the screw will be away from the tail end of the screw head. After it is separated from the nut, not only will the screw be loosened directly from the hardware, but the nut will also easily fall off alone, causing the screw and the nut to fall off. It is also necessary to find nuts and screws that match each other, which is not only time-consuming and labor-intensive, but also easily causes the loss of fasteners, affecting the safety of power engineering.

DETAILED DESCRIPTION

[0035] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] For example, see Figure 1-15The present invention provides a technical solution: a high-voltage connection hardware for power lines, comprising a limiting base plate 1 and an upper clamping piece 2, the upper end of the limiting base plate 1 is fixedly connected with a lower clamping plate 11, the limiting base plate 1 and the lower clamping plate 11 are an integrated structure, arc grooves 12 are respectively provided on the inner walls of both sides of the lower clamping plate 11, the lower surface of the upper clamping piece 2 is movably connected with the upper surface of the lower clamping plate 11, circular perforations are respectively provided on the inner walls of the lower clamping plate 11 and the upper clamping piece 2, a wire clamping installation mechanism 3 is movably installed on the inner surface of the circular perforations, the wire clamping installation mechanism 3 comprises a screw rod 31, a screw head component 32 and a nut component 33, the outer surface of the screw rod 31 is threadedly connected with a locking nut 34, the screw head component 32 is provided with an embedding groove 320, an integrated anti-dropping unit is arranged inside the embedding groove 320, the nut component 33 comprises a compensation block 331, and a receiving groove 330 is formed between the compensation block 331 and the nut component 33 The receiving groove 330 is provided with a screw limiting unit, which includes a fixing seat 332 and a rotating rod 333. The outer surface of the rotating rod 333 is rotatably connected with a rotating rod anti-rotation assembly, and the rotating rod anti-rotation assembly includes an anti-rotation ring 335; the integrated anti-slip unit includes an anti-slip gasket 321 and an embedded block 322. The inner surface of the anti-slip gasket 321 is movably connected to the outer surface of the screw 31, and one side of the outer surface of the anti-slip gasket 321 is connected to the embedded block 322. The outer surface of the embedded block 322 is movably embedded with the inner wall of the embedded groove 320; a reserved groove 110 is provided on the inner wall of the upper end of the lower clamping plate 11, and the inner surface of the reserved groove 110 is movably overlapped with the lower surface of another set of limiting bottom plates 1, and one end of the lower clamping plate 11 and the upper clamping piece 2 are respectively fixedly connected with the upper arc groove plate 41 and the lower arc groove plate 42, and the inner walls of the upper arc groove plate 41 and the lower arc groove plate 42 are respectively provided with contraction grooves 43;

[0037] An integrated anti-dropping unit is designed at one end of the screw head component 32, and the anti-dropping gasket 321 is integrated with the screw head component 32, ensuring a flexible connection with the clamping plate while avoiding the loss of the anti-dropping gasket 321, which is convenient for assembly; the screw limit unit design not only meets the anti-dropping requirement between the locking nut 34 and the screw 31 after the lower clamping plate 11 and the upper clamping piece 2 are adapted and installed, but also limits the storage of the locking nut 34 after the upper clamping piece 2 is disassembled, further preventing the screw 31 from falling off, ensuring that the screw 31 and the locking nut 34 are connected to the lower clamping plate 11 when the hardware is not in use, thereby improving the stability and safety of the power line connection, effectively preventing the nut and the screw from loosening and losing, greatly reducing the construction difficulty and cost, and ensuring the efficient and stable operation of the power facilities;

[0038] Reserved grooves 110 are respectively formed at the upper ends of the lower clamping plates 11, which can ensure that multiple groups of lower clamping plates 11 are stacked conveniently when in the storage state, avoid scattered storage, facilitate storage, and effectively improve the space utilization rate. The reason for forming multiple arc grooves 12 on the lower clamping plates 11 is to achieve product lightweighting, optimize and reduce the weight of the fittings, help reduce the overall load of the transmission line, and improve economic benefits. In addition, upper placement arc groove plates 41 and lower placement arc groove plates 42 are respectively arranged at both ends of the lower clamping plates 11 and the upper clamping pieces 2. With the formation of the contraction grooves 43, the elastic stress of the upper placement arc groove plates 41 and the lower placement arc groove plates 42 is increased, which can reduce the deformation and wear of the two end parts where the wire contacts the fittings after the line is clamped, and further improve the safety of the power line.

[0039] Embodiment 2. Referring to the attached Figure 1-15 , on the basis of Embodiment 1, in order to achieve the compensation of the nut component 33 part and facilitate the installation of the screw limiting unit: the剖切 section of the fixing seat 332 is in a "C" - shaped structure. The lower surface of the fixing seat 332 is fixedly connected to the inner cavity bottom surface of the receiving groove 330, and the upper end of the fixing seat 332 is fixedly connected to the lower surface of the compensation block 331. There are two groups of compensation blocks 331, and the two groups of compensation blocks 331 are symmetrically distributed about the central axis of the screw 31. Limiting grooves 3320 are respectively formed on the inner walls of both sides of the fixing seat 332, and a compensation blocking component is movably installed on the inner surface of the limiting grooves 3320;

[0040] In the receiving groove 330 of the nut component 33, the compensation block 331 is used as the compensation at the screw head. The receiving groove 330 as a whole forms a "concave" - shaped cavity structure. With the setting of the fixing seat 332, it provides limits for the movement of the two locking blocks 334. At the same time, when the locking blocks 334 are in the initial retracted state, it ensures the compensation filling of the limiting grooves 3320 and does not affect the normal use of the nut component 33 part.

[0041] Embodiment 3. Referring to the attached Figure 1-15 It should be noted that the Chinese text you provided contains some characters that seem incorrect or incomplete in the "剖切 section" part. I translated it as best as possible based on the context. If there are specific corrections or clarifications for that part, the translation can be adjusted accordingly.The nut 3320 of the embodiment 2 is provided with a locking block 334, and the locking block 3341 is fixedly installed with a connecting block 3341 at the end of the locking block 334 away from the connecting block 334. The connecting block 3341 is provided with two groups, and a "T"-shaped structure is formed between the two groups of connecting blocks 3341 and the locking block 334; a sliding piece 3342 is fixedly connected to the lower surface of the locking block 334, and the lower surface of the sliding piece 3342 is slidably connected to the bottom surface of the inner cavity of the receiving groove 330; an elastic rubber ring 3343 is fixedly connected to the outer surface of one side of the sliding piece 3342, and the other end of the elastic rubber ring 3343 is fixedly connected to the inner surface of the fixing seat 332; a rotating groove plate 334 is provided at the end of the locking block 334 away from the connecting block 3341 The outer surface of the lower end of the rotating slot plate 3332 is rotatably connected to the inner bottom surface of the fixed seat 332, and locking slots 3333 are respectively opened on the inner walls of both sides of the rotating slot plate 3332, and the inner surfaces of the locking slots 3333 are movably abutted against the outer surfaces of the locking blocks 334; the upper end of the rotating slot plate 3332 is fixedly connected to the lower surface of the rotating rod 333, and the outer surface of the rotating rod 333 is rotatably connected to the upper inner wall of the nut component 33, and the upper end of the rotating rod 333 is fixedly connected to the lower surface of the rotating rod 333. A force-bearing handle 3331 is connected; the outer surface of the upper end of the force-bearing handle 3331 is on the same horizontal plane as the top surface of the nut component 33, and a buckling groove 33311 and a pointer 33312 are respectively provided on the inner wall of the force-bearing handle 3331, and a scale groove 3300 is provided on the outer side of the pointer 33312. The scale groove 3300 is provided on the inner wall of the top end of the nut component 33, and the scale groove 3300 is provided in four groups, and the interval between two groups of scale grooves 3300 is 90°;

[0042] When the screw rod 31 passes through the circular through holes on both sides of the lower clamping plate 11, the circular through holes at both ends of the upper clamping plate 2 are aligned with the upper end of the screw rod 31 for passing through, and the lower clamping plate 11 is fitted over the upper clamping plate 2. Then, the locking nut 34 is rotated by one end of the nut component 33. After the locking nut 34 is initially sleeved on the inclined position outside the nut component 33, the locking nut 34 is continuously rotated and threadedly advanced by the screw rod 31. After the locking nut 34 is advanced, the finger is buckled into the buckling groove 33311 opened at the upper end of the force-bearing handle 3331. Then, the finger is forced to rotate the force-bearing handle 3331 and the rotating rod 333. At this time, the rotating slot plate 3332 rotates synchronously. When the force-bearing handle 3331 rotates 90 degrees, the position of the rotating slot plate 3332 changes, and At this time, the locking groove 3333 pushes out the sliding piece 3342 on the inner side, and the locking block 334 slides on the inner wall of the limiting groove 3320. At the same time, the connecting block 3341 connected to one end of the locking block 334 disengages from the limiting groove 3320. At this time, the locking block 334 and the connecting block 3341 extend out of the outside of the fixed seat 332. The sliding piece 3342 and the elastic rubber ring 3343 are connected to the lower surface of the locking block 334 to ensure that when the rotating groove plate 3332 rotates 90 degrees again, the locking block 334 as a whole can be automatically reset, that is, when the locking block 334 and the connecting block 3341 are extended, even if the locking nut 34 releases the restriction on the upper clamp 2, it will not be separated from the nut component 33 of the screw 31.

[0043] Embodiment 4, refer to the attached Figure 1-15 On the basis of the third embodiment, in order to prevent the rotating rod 333 from rotating without the action of external force: the anti-rotation ring 335 is set as a circular columnar structure, and the outer ring surface of the anti-rotation ring 335 is fixedly connected to the inner wall of the nut component 33, and the inner ring surface of the anti-rotation ring 335 is fixedly connected with a spacer 3351 and an elastic extrusion contact ring 3352, the spacer 3351 is set in multiple groups, and a group of elastic extrusion contact rings 3352 is set between two adjacent groups of spacers 3351, and the outer surfaces of both sides of the elastic extrusion contact rings 3352 are movably abutted against the outer surface of the spacer 3351;

[0044] The rotation of the rotating rod 333 is prevented by the outer ring surface of the compensation block 331, and the outer ring surface of the compensation block 331 contacts the outer surface of the elastic extrusion contact ring 3352. At this time, there is a certain resistance to the rotation of the rotating rod 333. When the rotation of the force-bearing handle 3331 and the rotating rod 333 is stopped, the rotating rod 333 is squeezed by the reverse elastic force of the elastic extrusion contact ring 3352, and a certain resistance is provided to the rotating rod 333. In this way, the rotating rod 333 is ensured not to deflect when not subjected to external force, thereby avoiding the retraction of the locking block 334 and the connecting block 3341, further avoiding the loosening of the locking nut 34, and preventing loss.

[0045] Embodiment 5, refer to the attached Figure 1-15 Based on the fourth embodiment, this embodiment proposes a method for using a high-voltage connection fitting for a power line:

[0046] Step 1: First, place the power line in the circular arc groove on the lower clamping plate 11, and then install the upper clamping plate 2 and the lower clamping plate 11 respectively. After the circular perforations are aligned with each other, the screw 31 is passed through the lower end of the lower clamping plate 11, and the lower clamping plate 11 and the upper clamping plate 2 are fitted together. Then, the locking nut 34 is rotated from one end of the nut component 33. After the locking nut 34 is initially sleeved on the inclined surface outside the nut component 33, the locking nut 34 is continuously rotated and threadedly advanced with the screw 31;

[0047] Step 2: After the locking nut 34 is pushed in, the finger is buckled into the buckling groove 33311 opened at the upper end of the force-bearing handle 3331, and then the finger is forced to rotate the force-bearing handle 3331 and the rotating rod 333. At this time, the rotating groove plate 3332 rotates synchronously. When the force-bearing handle 3331 rotates 90 degrees, the position of the rotating groove plate 3332 changes. At this time, the locking groove 3333 pushes out the sliding piece 3342 on the inner side, and the locking block 334 slides on the inner wall of the limiting groove 3320. At the same time, the connecting block connected to one end of the locking block 334 3341 is separated from the limiting groove 3320. At this time, the locking block 334 and the connecting block 3341 extend out of the outside of the fixing seat 332. The reason why the sliding piece 3342 and the elastic rubber ring 3343 are connected to the lower surface of the locking block 334 is to ensure that when the rotating groove plate 3332 rotates 90 degrees again, the locking block 334 as a whole can be automatically reset. That is, when the locking block 334 and the connecting block 3341 extend out, even if the locking nut 34 releases the restriction on the upper clamping piece 2, it will not be separated from the nut component 33 of the screw rod 31.

[0048] Step three: When the compensation block 331 rotates under force, the outer annular surface of the compensation block 331 contacts the outer surface of the elastic extrusion contact ring 3352. At this time, there is a certain resistance to the rotation of the rotating rod 333. When the rotation of the force-bearing handle 3331 and the rotating rod 333 is stopped, the rotating rod 333 is squeezed by the reverse elastic force of the elastic extrusion contact ring 3352, and a certain resistance is provided to the rotating rod 333. In this way, the rotating rod 333 is ensured not to deflect when not subjected to external force, thereby avoiding the retraction of the locking block 334 and the connecting block 3341, further avoiding the loosening of the locking nut 34 and preventing it from being lost.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
