Description

Technical Field

[0001] This invention belongs to the technical field of power line branching equipment, specifically relating to a branching device for power cables that facilitates line splitting. Background Technology

[0002] In power cable construction and laying operations, cable distribution devices are the core equipment for realizing the diversion, orderly arrangement, and zoned layout of multiple cables. They are widely used in power grid construction, power distribution projects, power line renovation and other scenarios, and their performance directly affects the efficiency of cable construction and the stability of line operation.

[0003] In the prior art, Chinese Patent No. CN118523224A discloses a novel cable splitting device for power cable construction. This device clamps and fixes the cable by setting a cover plate on the upper side of the shell, a mounting plate on the lower side, and a clamping assembly inside. The cable is clamped by the cooperation of a placement plate and a pressure plate, and the opening and closing of the placement plate and pressure plate is controlled by a second operating rod. However, this device has inconveniences in actual use: when it is necessary to disassemble, repair, or replace a single cable among multiple cables, the placement plate and pressure plate must be separated as a whole by the second operating rod. This operation will simultaneously loosen all the cables clamped between them, which can easily cause displacement, loosening, or even detachment of the remaining normally operating cables. It cannot achieve independent splitting of a single line, the operation is cumbersome, the practicality is poor, and it affects the efficiency of cable repair and construction.

[0004] Meanwhile, existing conventional cable distribution devices only have simple clamping and fixing functions. During the laying and long-term operation of cable distribution, it is inevitable that the cable distribution will be subjected to external impacts, pulling and vibrations in the horizontal and vertical directions. Existing devices cannot buffer and relieve multi-directional forces. External forces will directly act on the cable body, which can easily cause problems such as cable core misalignment, insulation wear, and loose connection. This not only reduces the service life of the cable, but also causes safety hazards such as poor line contact, leakage, and short circuit. It cannot meet the protection requirements of power cable distribution under complex working conditions. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and solve the problems mentioned in the above-mentioned technical background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power cable splitting device for easy line splitting, comprising a main box, wherein separate connected cables are placed inside the main box, and cable guide plates are fixedly installed on both the left and right sides of the main box. Multiple cable guide holes for cable passage are evenly arranged inside the cable guide plates. A cover plate is detachably installed on the upper side of the main box. Multiple support mechanisms are installed inside the main box, with the support mechanisms positioned opposite to the cable guide holes to support the cables passing through the holes. Each support mechanism includes two symmetrically arranged support seats, with side plates fixedly installed on the front and rear sides of each support seat. A tray is provided between the two side plates, and a cable clamping sleeve is fixedly installed on the upper side of the tray. The cable is clamped and fixed inside the cable clamping sleeve after passing through the support seat.

[0007] Preferably, the wire hole is a vertically placed strip-shaped hole, and a rubber pad is attached to the inner surface of the wire hole, with ball bearings embedded inside the rubber pad.

[0008] Preferably, a marking plate for marking is provided above the wire hole.

[0009] Preferably, the cable threading hole adopts a vertical strip structure, combined with a built-in rubber pad and ball bearings, which can not only limit and protect the cable, reduce friction loss during cable threading and movement, but also accommodate small vertical displacement of the cable, thus having stronger compatibility; at the same time, the marking signs can be set to mark each line independently, making it easier for staff to distinguish the lines and reduce the probability of wiring and maintenance errors.

[0010] Preferably, the cover plate includes a plurality of evenly arranged split plates, the position of each split plate corresponds to a single support mechanism, and the corners of the split plates are fixedly connected to the main body box by screws.

[0011] With its independently designed support mechanism and split plate, each branch cable can be operated individually while other branch cables remain unaffected, greatly improving the safety and practicality of the device.

[0012] Preferably, the support base is provided with a vertical buffer assembly, which includes an arc groove and a rotating rod. The arc groove is located inside the side plate, the lower end of the rotating rod is hinged to the side plate, the upper end of the rotating rod is fixedly connected to the tray, the outer side of the rotating rod is slidably engaged with the inside of the arc groove by an arc pin, and a vertical elastic element is fixedly provided between the rotating rod and the bottom of the support base.

[0013] Preferably, the clamp sleeve includes two symmetrically arranged semicircular rings, with extended sides extending from the two semicircular rings along the notch, and fastening bolts passing through the extended sides to connect and fix the two semicircular rings.

[0014] Preferably, the wire clamp sleeve is provided with a horizontal buffer assembly, which includes symmetrically arranged wire clamping arc plates. The outer side of the wire clamping arc plates is provided with a surface groove in the horizontal direction. A plug rod is fixedly provided on the inner side of the semi-circular ring. The lower end of the plug rod is inserted into the surface groove. Horizontal elastic members are provided between the left and right sides of the plug rod and the surface groove.

[0015] Preferably, the vertical buffer component and the horizontal buffer cooperate with each other to buffer the multi-directional displacement of the cable. When subjected to vertical or lateral impact, the cable will drive the clamp sleeve and tray to move up and down, thereby driving the rotating rod to rotate along the arc groove. The vertical impact force is buffered by the vertical elastic element, and the lateral impact force is buffered by the horizontal elastic element, thus providing overall buffering for the impact on the cable.

[0016] Preferably, the support base is provided with a wiring mechanism, which includes a terminal block. The front and rear sides of the terminal block are fixedly connected to the side plate, and the cable passes through the interior of the terminal block.

[0017] Preferably, a clamping assembly is provided on the lower side of the terminal block. The clamping assembly includes an arm seat and a lower support seat. The arm seat is fixedly disposed on the side of the terminal block near the wire clamp sleeve. A support arm is movably disposed through the arm seat. The end of the support arm away from the terminal block is fixedly connected to the wire clamp sleeve. The lower support seat is fixedly disposed at the bottom of the terminal block. A triangular block is hinged inside the lower support seat. The end of the support arm near the terminal block is hinged to the lower end of the triangular block. A top wire block is hinged to the upper end of the triangular block.

[0018] Preferably, the top wire block is movably disposed at the bottom of the terminal block, and the upper side of the top wire block is provided with an arc-shaped groove with anti-slip texture.

[0019] This invention provides a power cable splitting device that facilitates line splitting, and has the following beneficial effects: This device adopts a split-plate cover structure, with each split plate corresponding to a single support mechanism and a single cable. Each split plate can be disassembled individually, and with the independent clamping sleeve structure, it can realize the individual disassembly, inspection and replacement of a single cable without opening the entire cover or loosening other cable fixing structures. This solves the problem of interference with other normal lines when splitting a single line in existing devices, making it easy to operate and greatly improving the efficiency of cable splitting and maintenance operations.

[0020] By combining vertical and horizontal buffer components, bidirectional vertical and horizontal buffering protection for cables can be achieved. When the cable is subjected to vertical impact, pulling, or vibration, the tray drives the rotating rod to rotate along the arc groove, compressing the vertical elastic element to buffer the vertical force. When the cable is subjected to horizontal force, the clamping arc plate compresses the horizontal elastic element to relieve lateral force. The multi-directional buffering structure effectively offsets external forces, preventing direct damage to the cable insulation layer and core, eliminating safety hazards such as loose lines, short circuits, and leakage, and significantly improving the operational stability and service life of the cable.

[0021] This device is equipped with a dedicated wiring mechanism and clamping components. It forms a double clamping and fixing structure through the top wire block and the clamping sleeve. When the cable is pulled and displaced by external force, the arc anti-slip groove of the top wire block cooperates with the clamping arc plate, which greatly improves the cable clamping firmness and effectively avoids the problem of loosening and displacement of the cable during long-term use. It has strong structural stability and is suitable for various complex power construction conditions. Attached Figure Description

[0024] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0025] Please see Figures 1 to 3 A power cable splitting device for easy line splitting includes a main box 100, inside which separate and connected cables 200 are placed. Cable guide plates 101 are fixedly installed on both the left and right sides of the main box 100. Multiple cable through holes 102 are evenly arranged inside the cable guide plates 101 for the cables 200 to pass through, so as to realize the orderly splitting of the cables.

[0026] The main body box 100 has a detachable cover plate 104 on its upper side. The cover plate 104 is composed of multiple evenly arranged split plates 1041. Each split plate 1041 is set in a one-to-one correspondence with a single support mechanism 300 and a single cable 200. The four corners of the split plate 1041 are fixedly connected to the main body box 100 by fastening screws. This allows for the independent assembly and disassembly of a single split plate 1041 without the need to disassemble the cover plate 104 as a whole, providing a structural basis for the independent splitting of a single cable.

[0027] Multiple support mechanisms 300 are fixedly installed inside the main box 100. Each support mechanism 300 corresponds to a cable hole 102 and is used to support and fix the cable 200 passing through the cable hole 102. The support mechanism 300 includes two symmetrically arranged support seats 301. Side plates 302 are fixedly connected to the front and rear sides of the support seats 301. A tray 303 is movably installed between the two side plates 302. A cable clamping sleeve 304 is fixedly installed on the upper side of the tray 303. After the cable 200 passes through the support seat 301, it is clamped and fixed inside the cable clamping sleeve 304, realizing the independent fixation of a single cable.

[0028] Furthermore, the cable passage 102 is designed as a vertical strip-shaped hole structure to accommodate the small vertical buffer displacement requirements of the cable. A rubber pad layer is bonded to the inner surface of the cable passage 102, and multiple ball bearings 1021 are evenly embedded inside the rubber pad layer. The rubber pad layer can provide insulation protection and reduce cable wear, while the ball bearings 1021 can significantly reduce the friction during cable insertion and displacement, preventing the cable insulation layer from being scratched. At the same time, a marking plate 103 is fixedly installed above each cable passage 102 to number and mark the cable line at the corresponding location, making it convenient for staff to identify and repair the line and avoid wiring confusion.

[0029] In this embodiment, during wiring operations, multiple cables 200 are passed through the cable holes 102 of the cable guide plates 101 on both sides of the main box 100, corresponding to the support mechanism 300 and the cable clamp sleeve 304. The wiring is marked using the marking plate 103. The cable clamp sleeve 304 is used to fix the cable 200 inside the support base 301, completing the independent fixing of each individual cable branch. Finally, each split plate 1041 is installed and fixed on the upper side of the main box 100, completing the overall wiring. For single-line disassembly and maintenance, only the single split plate 1041 above the corresponding cable 200 needs to be removed, and the corresponding cable clamp sleeve 304 loosened. The cable 200 can then be individually removed for maintenance or replacement without touching or loosening the fixing structure of other cables 200, and without affecting other normally operating lines. The disassembly operation is efficient and convenient.

[0030] Please see Figures 4 to 6 In another embodiment, a vertical buffer assembly is provided inside the side plate 302. Specifically, an arc groove 3021 is formed on the inner side of the side plate 302. The lower end of the rotating rod 3022 is hinged to the bottom of the side plate 302, and the upper end of the rotating rod 3022 is fixedly connected to the bottom surface of the tray 303. An arc pin 3023 is fixedly installed on the outer side of the rotating rod 3022, and the arc pin 3023 is slidably engaged inside the arc groove 3021, allowing the rotating rod 3022 to rotate slightly along the trajectory of the arc groove 3021. A vertical elastic element 3024 is fixedly connected between the rotating rod 3022 and the bottom of the support base 301. The vertical elastic element 3024 is preferably a compression spring. When the cable is subjected to vertical impact or pulling force, the cable drives the clamp sleeve 304 and the tray 303 to vertically displace, driving the rotating rod 3022 to rotate along the arc groove 3021, compressing the vertical elastic element 3024. The elastic deformation of the vertical elastic element 3024 absorbs and buffers the vertical impact force, achieving vertical protection. During the movement of the rotating rod 3022, the horizontal displacement between the clamp sleeve 304 and the cable 200 can be buffered by the horizontal elastic element 3046.

[0031] The cable clamp 304 consists of two symmetrical semicircular rings 3041. The notched ends of the two semicircular rings 3041 extend outward to form extended sides. Fastening bolts 3042 are installed through the upper and lower corresponding extended sides. The two semicircular rings 3041 are locked and fixed by the fastening bolts 3042, thereby achieving the wrapping and clamping of the cable 200. During disassembly and assembly, it is only necessary to loosen the corresponding fastening bolts 3042 to achieve the loosening and disassembly of a single cable without interference from other lines.

[0032] The cable clamp sleeve 304 has a horizontal buffer assembly inside. Two semi-circular rings 3041 have symmetrically arranged clamping arc plates 3043 on their inner sides. The inner side of the clamping arc plates 3043 fits against the outer surface of the cable. A surface groove 3045 is horizontally formed on the outer side of the clamping arc plates 3043. A plug rod 3044 is fixedly installed inside the semi-circular rings 3041. The lower end of the plug rod 3044 slides into the surface groove 3045. Horizontal elastic elements 3046 are fixedly connected between the left and right sides of the plug rod 3044 and the groove wall of the surface groove 3045. The horizontal elastic elements 3046 are preferably compression springs. When the cable is subjected to horizontal pulling, vibration, or impact, the cable causes the clamping arc plates 3043 to shift slightly horizontally, compressing the corresponding horizontal elastic elements 3046. The elastic deformation of the horizontal elastic elements 3046 buffers the horizontal force, preventing horizontal damage to the cable.

[0033] In this embodiment, during the installation and operation of the line, when the cable 200 is subjected to vertical impact or pulling, the tray 303 and the clamp sleeve 304 move vertically with the cable, causing the rotating rod 3022 to rotate along the arc groove 3021, squeezing the vertical elastic element 3024. The deformation of the vertical elastic element 3024 buffers the vertical impact force. When the cable is subjected to horizontal external force, the clamp arc plate 3043 squeezes the horizontal elastic element 3046. The deformation of the horizontal elastic element 3046 offsets the horizontal force. The bidirectional buffer structure provides all-round protection for the cable line, avoids external force damage, and ensures the long-term stable operation of the line.

[0034] Please see Figures 7 to 8 In another embodiment, a wiring mechanism 400 is fixedly installed inside the support base 301. The wiring mechanism 400 includes a terminal block 401, the front and rear ends of which are fixedly connected to the side plate 302. The cable 200 passes through the inside of the terminal block 401 to complete the wiring. A clamping assembly 402 is installed on the lower side of the terminal block 401 to assist in clamping and fixing the cable, thereby improving the stability of the line.

[0035] The clamping assembly 402 includes an arm base 4021 and a lower support base 4022. The arm base 4021 is fixedly connected to the side of the terminal block 401 near the wire clamping sleeve 304. A support arm 4023 is slidably installed through the arm base 4021, and the outer end of the support arm 4023 is fixedly connected to the bottom of the wire clamping sleeve 304. The lower support base 4022 is fixed to the bottom of the terminal block 401. A triangular block 4024 is hinged inside the lower support base 4022. The inner end of the support arm 4023 is hinged to the lower end of the triangular block 4024. A top wire block 4025 is hinged to the upper end of the triangular block 4024. The top wire block 4025 slides against the bottom of the terminal block 401. An arc groove is opened on the upper side of the top wire block 4025, and anti-slip texture is set inside the groove, which can closely fit the bottom surface of the cable 200 and improve the clamping anti-slip effect.

[0036] In this embodiment, when the cable 200 is subjected to external impact, the impact force within a certain limit will be mitigated by the vertical and horizontal buffer components. When the impact force is large, exceeding the elastic limit of the horizontal elastic element 3046, the cable 200 will move the clamping sleeve 304 away from the terminal block 401 via the clamping arc plate 3043. At this time, the clamping sleeve 304 moves the triangular block 4024 via the support arm 4023. The triangular block 4024 rotates around the hinge point with the lower support 4022, thereby moving the top block 4025 upward, so that the internal groove of the top block 4025 continuously clamps the cable 200, preventing the cable 200 from detaching from the terminal block 401 and ensuring the safety of the cable connection.
