Description

Technical Field

[0001] This invention relates to the field of cable protection technology, and in particular to a cable dynamic balancing device. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Cables in the cable interlayer are prone to displacement due to thermal expansion and contraction. This displacement increases friction with supports or other cables, leading to insulation damage. Cable shrinkage can affect the stability of the connection between the ends and joints. Furthermore, decreased insulation performance and tension pressure on the cable can increase the risk of failure. To prevent cables from rubbing against each other due to thermal expansion and relaxation, and to enable cables to adapt to expansion and contraction with appropriate tension, the inventors proposed a dynamic balancing device for power cable expansion and contraction to solve the above problems. However, since three-phase cables are usually laid in a triangular pattern in the cable interlayer, the spacing between cables is too small, and they may even come into contact with each other. The above-mentioned device can only adaptively adjust straight-laid cables and cannot handle cables arranged in a triangular pattern. If the triangular cables are pressed down to adapt to expansion and contraction, the following problems exist: 1. The cables in a triangular pattern are too close together, and their outer sheaths are easily damaged due to friction after expansion; 2. When the cables expand thermally, the small spacing makes it difficult for heat to dissipate, affecting cable safety. Therefore, a dynamic balancing device for cables is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a dynamic cable balancing device that increases the spacing of the cable during thermal expansion, thereby ensuring the cable's safety and effective heat dissipation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a cable dynamic balancing device, comprising:

[0006] At least one mounting bracket, on which two balancing components are disposed in opposite directions;

[0007] A guide component is provided at the moving end of the balancing component. The cable bodies are arranged in a triangular pattern with gaps between them. The guide component includes three rings arranged in a triangular pattern. Each cable body passes through a corresponding ring and does not contact the others. The mounting bracket has reserved space for the guide component to move downwards at the position corresponding to the guide component. The balancing component can drive the guide component to move downwards when the cable body expands due to heat, causing the cable body to bend downwards, and return to its original position when the cable body contracts due to cold.

[0008] An expansion assembly, mounted on a mounting bracket, is capable of widening the gaps between cable bodies arranged in a triangular pattern as the guide assembly moves downward.

[0009] Furthermore, the balancing assembly includes a housing mounted on a mounting bracket, with a spring vertically disposed inside the housing. The bottom of the spring contacts the guide assembly, which is used to press the guide assembly downward when the cable body stretches due to thermal expansion.

[0010] Furthermore, the housing also includes a screw threaded onto the housing, and a strip-shaped guide groove is vertically formed on the inner wall of the housing. A pressing plate is rotatably disposed at the bottom of the screw, and the pressing plate is slidably disposed at the corresponding guide groove of the housing. The pressing plate is in contact with the top of the spring. Rotating the screw can drive the pressing plate to rise and fall, thereby changing the elastic force applied by the spring to the guide assembly.

[0011] Furthermore, the guiding assembly includes a slidably mounted lifting platform at a corresponding guide groove in the housing. The bottom of the spring is connected to the lifting platform. A telescopic rod with a compression spring is laterally arranged on the side of the lifting platform near the cable body. A first mounting ring is provided at the telescopic end of the telescopic rod. The first mounting ring is sleeved on the corresponding bottom cable body in the triangularly distributed cable body. A connecting frame is provided on the telescopic rod. A second mounting ring is provided at the bottom of the connecting frame. The second mounting ring is sleeved on the corresponding top cable body in the triangularly distributed cable body. The expansion assembly can shorten the telescopic rod when it moves.

[0012] Furthermore, the expansion assembly includes a pressing block disposed on each of the first mounting rings, and an adjusting block corresponding to the pressing block is disposed on the mounting frame. The top of the adjusting block has an inclined surface. When the balancing assembly drives the guiding assembly to move downward, the pressing block abuts against the inclined surface of the adjusting block and drives the telescopic rod to retract.

[0013] Furthermore, rollers are rotatably provided on the inner walls of both the first and second mounting rings, and the rollers are in contact with the corresponding cable bodies.

[0014] Furthermore, it also includes at least two mounting seats, each of which is respectively disposed on both sides of the mounting frame. Each mounting seat includes a base for the cable body to pass through. The inner side of the base is provided with a Y-shaped partition frame, which is used to separate the three cable bodies distributed in a triangular pattern. The partition frame is provided with multiple roller belt groups, which are used to reduce the friction generated by the cable body during expansion and contraction.

[0015] The beneficial effects of this invention are reflected in:

[0016] In this invention, three cable bodies are arranged in a triangular shape and pass through a guiding component without touching each other. The guiding component supports the cable bodies. When the temperature is low, the three cable bodies gradually straighten. When the temperature rises, the cable bodies absorb heat and expand, becoming longer. At this time, the balancing component drives the guiding component to move downward, causing the cable bodies to bend downward and maintain corresponding tension. During this process, the expansion component moves and widens the gap between the cable bodies. This not only prevents mutual interference between the cables but also allows for better heat dissipation. At the same time, this device can adapt to the expansion and contraction of the cable bodies, ensuring that the cable bodies always have appropriate tension, making them suitable for practical use.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-4 The present invention discloses a cable dynamic balancing device, including cable bodies 4 arranged in a triangular shape and at least one mounting frame 1. The mounting frame 1 is provided with two balancing components 2 arranged opposite to each other, and the moving end of the balancing component 2 is provided with a guide component 3.

[0025] In one embodiment, the cable bodies 4 arranged in a triangular pattern have gaps between them. The guide assembly 3 includes three rings arranged in a triangular pattern. Each cable body 4 passes through the corresponding ring and does not contact each other. The mounting bracket 1 has reserved space at the position of the guide assembly 3 for the guide assembly 3 to move downward. The balancing assembly 2 can drive the guide assembly 3 to move downward when the cable body 4 expands thermally, so that the cable body 4 bends downward and resets when the cable body 4 contracts cold.

[0026] In practice, three cable bodies 4 are arranged in a triangular shape and pass through the guide component 3 without touching each other. The guide component 3 supports the cable bodies 4. When the temperature is low, the three cable bodies 4 are gradually straightened. When the temperature rises, the cable bodies 4 absorb heat and expand, becoming longer. At this time, the balance component 2 will drive the guide component 3 to move downward, causing the cable bodies 4 to bend downward and maintain the corresponding tension. During this process, the expansion component 6 moves and widens the gap between the cable bodies 4. This can prevent mutual interference between the cables and allow heat to dissipate better, thus facilitating practical use.

[0027] In one embodiment, the balancing assembly 2 includes a housing 21 mounted on the mounting bracket 1, with a spring 22 vertically disposed on the inner side of the housing 21. The bottom of the spring 22 contacts the guide assembly 3 and is used to press the guide assembly 3 downward when the cable body 4 is stretched due to thermal expansion.

[0028] With this design, when the temperature is high, the cable body 4 expands and lengthens. At this time, the spring 22 will apply a downward elastic force to the guide component 3, causing the cable body 4 to bend downward and maintain the corresponding tension. When the temperature is low, the cable body 4 contracts. At this time, the bent cable body 4 will gradually straighten and cause the spring 22 to contract upward and tighten, so as to ensure that the cable body 4 can adapt to expansion and contraction and has the corresponding tension, with moderate tightness.

[0029] In one embodiment, the housing 21 further includes a screw 23 screwed onto the housing 21. A strip-shaped guide groove 25 is vertically formed on the inner wall of the housing 21. A pressing plate 24 is rotatably mounted on the bottom of the screw 23. The pressing plate 24 is slidably mounted on the corresponding guide groove 25 of the housing 21, and the pressing plate 24 contacts the top of the spring 22. Rotating the screw 23 can drive the pressing plate 24 to rise and fall, thereby changing the elastic force applied by the spring 22 to the guide assembly 3.

[0030] With this design, when the screw 23 rotates and moves the extrusion plate 24 closer to the spring 22, the spring 22 contracts and increases the elastic force applied to the guide assembly 3; while when the screw 23 rotates to the other side and moves the extrusion plate 24 away from the spring 22, the spring 22 expands and reduces the elastic force applied to the guide assembly 3, so as to flexibly adjust the bending range of the cable body 4 according to the actual situation. It should also be noted that when the elastic force applied by the spring 22 to the guide assembly 3 is set, its elastic force is insufficient to affect the connection stability between the end of the cable body 4 and the corresponding connection point.

[0031] In one embodiment, the guide assembly 3 includes a lifting platform 31 slidably mounted at a corresponding guide groove 25 in the housing 21. The bottom of the spring 22 is connected to the lifting platform 31. A telescopic rod 32 with a compression spring is laterally mounted on the side of the lifting platform 31 near the cable body 4. A first mounting ring 33 is mounted on the telescopic end of the telescopic rod 32. The first mounting ring 33 is sleeved on the corresponding bottom cable body 4 in the triangular arrangement of the cable bodies 4. A connecting frame 34 is mounted on the telescopic rod 32. A second mounting ring 35 is detachably mounted on the bottom of the connecting frame 34. The second mounting ring 35 is sleeved on the corresponding top cable body 4 in the triangular arrangement of the cable bodies 4.

[0032] With this design, when the spring 22 compresses the lifting platform 31 to lower it, the first mounting ring 33 and the second mounting ring 35 will drive each cable body 4 to lower together. When the cable body 4 is cooled and straightened, it will also drive the first mounting ring 33 and the second mounting ring 35 to rise. When the expansion component 6 moves, it can shorten the telescopic rod 32, which will increase the gap between the cable bodies 4 located at the bottom. Therefore, it can prevent the cable bodies 4 from contacting each other when they are thermally expanded, and also improve their heat dissipation efficiency.

[0033] In one embodiment, the expansion assembly 6 includes a compression block 61 mounted on each of the first mounting rings 33, and the mounting bracket 1 is equipped with an adjustment block 62 corresponding to the compression block 61, the top of the adjustment block 62 having a slope.

[0034] In practice, when the balancing component 2 drives the guiding component 3 to move downward, the squeezing block 61 descends synchronously and abuts against the inclined surface of the adjusting block 62. As the descent continues, the squeezing block 61 is abutted against by the inclined surface of the adjusting block 62 and moves away from the cable body 4, thereby causing the telescopic rod 32 to retract and widening the gap between the two cable bodies 4 at the bottom.

[0035] In one embodiment, rollers (not shown in the figure) are rotatably mounted on the inner walls of both the first mounting ring 33 and the second mounting ring 35, and the rollers are in contact with the corresponding cable bodies 4.

[0036] With this design, when the cable body 4 is displaced in the corresponding first mounting ring 33 and second mounting ring 35 due to expansion and contraction, the friction on the surface of the cable body 4 can be reduced by the setting of the rollers. In practical cases, a soft protective layer, such as silicone, can be covered on the rollers for practical use.

[0037] In one embodiment, the device further includes at least two mounting bases 5, each mounting base 5 being disposed on both sides of the mounting frame 1. Each mounting base 5 includes a base body 51 through which the cable body 4 passes. A positioning plate 52 with perforations is mounted on the base body 51. A Y-shaped separator 53 is mounted on the inner side of the base body 51. The separator 53 is used to separate the three cable bodies 4 distributed in a triangular pattern. A plurality of roller belt groups 54 are disposed on the separator 53. Each roller belt group 54 consists of a plurality of rotatable rollers mounted on the separator 53 and a belt that is tractably disposed on the rollers.

[0038] With this design, the function of the roller belt assembly 54 is to reduce the friction generated by the cable body 4 during expansion and contraction. In use, bolts are installed at the corresponding through holes of the positioning plate 52 so that the mounting base 5 can be installed on the cable interlayer's support. Its function is to standardize the gathering of the cable bodies 4 distributed in a triangular pattern. At the same time, due to the setting of the separator 53 and the roller belt assembly 54, the cable bodies 4 can be located inside the base 51 without contacting or interfering with each other. It can also effectively reduce the friction caused by displacement during expansion and contraction.

[0039] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
