Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cable preparation, and particularly relates to an anti-erosion and anti-aging cable and a preparation method thereof. BACKGROUND

[0002] As a key carrier for power transmission and information transmission, cables are subjected to the influence of natural factors such as wind, sunlight and rain for a long time in outdoor environments. The traditional round-section cable has obvious defects when used in outdoor suspension: when the wind blows vertically to the cable, periodic vortex shedding will occur behind the cable, causing vortex-induced vibration. This continuous vibration will cause cable material fatigue, structural damage and shortened service life.

[0003] At present, outdoor cables usually adopt a round cross-section design. This structure is prone to obvious pressure concentration areas under the action of wind. When the wind direction changes, the round cable will form a larger wind resistance at a certain angle due to the symmetrical structure characteristics, causing the cable to sway more severely. Long-term wind-induced vibration not only causes the outer shell to wear, but also causes the internal conductor to fatigue and break, seriously threatening power supply safety. In order to solve the problem of wind-induced sway, the prior art attempts to increase the thickness of the cable outer shell or use high-strength materials, but these methods will significantly increase the cost and weight, and the effect is limited. Some schemes add spiral stripes or grooves to the surface of the cable, but these structures are prone to accumulate dust and moisture, accelerating material aging. SUMMARY

[0004] Therefore, the technical problem to be solved by the present application is to provide an anti-erosion and anti-aging cable and a preparation method thereof.

[0005] An anti-erosion and anti-aging cable preparation device, comprising a fixed column and an auxiliary seat, two auxiliary seats are arranged on the fixed column, a connecting rod is arranged on the auxiliary seat of the fixed column, the other end of the connecting rod is connected with the other auxiliary seat, a rotating part is rotatably connected between the two auxiliary seats, and a supporting arc plate is slidably connected to the rotating part.

[0006] A rotating rod is further connected to the fixed column, a transmission plate is fixedly connected to the rotating rod, a plurality of arc protrusions are fixedly connected to the transmission plate, a contact round rod is fixedly connected to the supporting arc plate, and a first compression spring is fixedly connected between the supporting arc plate and the rotating part.

[0007] A plurality of moving arc plates are connected to each auxiliary seat.

[0008] A driven rod is fixedly connected to each moving arc plate, a sliding rod is fixedly connected to each driven rod, and the plurality of sliding rods are slidably connected to the two auxiliary seats.

[0009] The anti-erosion and anti-aging cable preparation device is used for a preparation method of antibacterial plastic, and the method comprises the following steps:

[0010] Step one: Put the fixed column and auxiliary seat assembly into the inner circular groove of the cable outer shell, and make sure that the rectangular block is clamped into the side groove to realize circumferential positioning;

[0011] Step two: Drive the rotating rod to drive the cam on the driving block, push the driven rod to make the multiple moving arc plates press the inner wall of the inner circular groove, and realize axial fixation;

[0012] Step three: Start rotating the rotating part, and the contact circular rod moves along the transmission plate under the action of the first compression spring, periodically contacts the arc protrusion to make the supporting arc plate radially pop out, and provides local bonding support;

[0013] Step four: At the position where the supporting arc plate is lifted, sequentially bond triangle block A and triangle block B to the inner wall of the cable outer shell to ensure sufficient contact;

[0014] Step five: After completing a section of bonding, reverse rotate the rotating rod to make the moving arc plate retract, and use the mechanical hand to axially move the cable outer shell to the next unprocessed section;

[0015] Step six: Repeat steps two to five until the entire inner circular groove is processed. BRIEF DESCRIPTION OF DRAWINGS

[0026] The cable comprises a cable outer shell 101, a plurality of triangular blocks A 102 and a plurality of triangular blocks B 103 are fixedly connected on the cable outer shell 101, and an inner circular groove 105 is formed on the cable outer shell 101.

[0027] The cable inner core is installed in the inner circular groove 105, and the cable inner core is wrapped and protected by the cable outer shell 101, and when the cable is blown by external wind after outdoor erection, when the wind passes through the cable outer shell 101 with an elliptical cross section, the elliptical shape can make the cable bear force more evenly when the wind direction changes, reduce the wind pressure concentration effect, thereby effectively reducing the shaking of the cable during the suspension erection process, avoiding local excessive fatigue, and achieving the anti-aging effect.

[0028] When the wind direction changes, the elliptical shape helps to more evenly distribute the wind pressure on the surface of the cable, avoiding the obvious pressure concentration area of the circular cable at a certain angle, thereby reducing local fatigue;

[0029] And when the wind blows on the cable, the sharp triangular front edge and the smooth inclined surface can very smoothly split the airflow and guide it to both sides, minimizing the disordered turbulence and periodic vortex generated behind the cable, this design can greatly destroy the formation of large-scale, energy-containing vortex, and convert it into small-scale, fast-dissipating turbulence, thereby effectively suppressing vortex-induced vibration and improving stability, thereby effectively suppressing the vortex-induced vibration that causes the cable to shake, and improving the stability from the root;

[0030] At the same time, the triangular blocks A 102 and the triangular blocks B 103 can also strengthen the strength of the cable outer shell 101, so that the cable outer shell 101 will not bend in a large range, thereby enabling the cable outer shell 101 to effectively resist the lateral pressure of the wind, preventing the cable from being excessively bent, thereby achieving the effects of wind erosion resistance and anti-aging;

[0031] Further, the plurality of triangular blocks A 102 and the plurality of triangular blocks B 103 can also form a natural rainwater channel during actual use, rainwater will naturally flow down along the surfaces of the plurality of triangular blocks A 102 and the plurality of triangular blocks B 103, and will not accumulate on the surfaces, which greatly reduces rainwater erosion and avoids accelerated aging due to the long-term existence of water film, and the smooth and inclined surface itself is not conducive to the adhesion of dust and pollutants, even if there is a small amount of dust, it can also be easily washed away by wind and rainwater, and the self-cleaning ability is much stronger than the structure with grooves, further realizing the effects of wind erosion resistance and anti-aging.

[0032] The plurality of triangular blocks A102 and the plurality of triangular blocks B103 are oppositely oriented, the plurality of triangular blocks A102 are located on the left side of the cable outer shell 101, and the plurality of triangular blocks B103 are located on the right side of the cable outer shell 101.

[0033] The oppositely oriented arrangement of the plurality of triangular blocks A102 and the plurality of triangular blocks B103 allows the wind to be split by the triangular blocks A102 or the triangular blocks B103 at a certain position on the cable outer shell 101 when the wind blows along different wind directions, thereby fully achieving the effect of reducing the disordered turbulent flow and periodic vortex generated behind the cable, so that no matter which side the wind comes from, the triangular blocks on one side of the cable can effectively split the airflow with their sharp leading edges and smooth slopes, and guide it smoothly to both sides. This ensures that the generation of periodic vortex is maximized to inhibit vortex-induced vibration that leads to material fatigue;

[0034] At the same time, it can also further facilitate the guidance of rainwater on the cable outer shell 101, allowing rainwater to be discharged from the position of the triangular blocks A102 or the triangular blocks B103, and perfecting the wind erosion resistance and anti-aging effect. In rainy days, this oppositely oriented structure naturally forms a watershed effect, and after the rain falls on the top of the cable, it will naturally flow to both sides and quickly drain along the slope of the triangular blocks. This active guidance and drainage of rainwater greatly avoids the accumulation or turbulent flow of rainwater on the surface of the cable, effectively reduces rainwater erosion, and improves self-cleaning ability;

[0035] Embodiment 1 of the wind erosion resistant and anti-aging cable: when the cable needs to be built in an outdoor environment with strong wind, a plurality of triangular blocks A102 and a plurality of triangular blocks B103 can be arranged in a radial equidistant ring shape, each ring including three triangular blocks A102 on the left side and three triangular blocks B103 on the right side. This design not only splits and guides the wind, suppresses frequent high-strength vibration of the cable, but also allows the space between the multiple rings of the cable to have a certain deformability, thereby allowing the cable outer shell 101 to slightly bend when the wind is strong, thereby relieving stress and effectively avoiding the situation where the cable outer shell 101 is too rigid and is damaged after being subjected to strong wind for a long time. This design cleverly avoids the risk of structural brittle fracture due to excessive rigidity, and absorbs and dissipates wind energy through slight deformation, like a miniature buffer joint, greatly improving the fatigue resistance and survival ability of the cable under extreme wind load;

[0036] Embodiment 2 of the wind-erosion-resistant and anti-aging cable arrangement: when the cable needs to be built in an outdoor environment with weak wind, a plurality of triangular blocks A 102 and a plurality of triangular blocks B 103 are arranged in a continuous spiral, so that the spiral arrangement of the plurality of triangular blocks A 102 and the plurality of triangular blocks B 103 can better cope with wind from different directions, provide all-around stability, and improve the wind-erosion-resistant and anti-aging effect;

[0037] For an environment with variable wind direction but weak wind, the spiral arrangement scheme provides optimal omnidirectional stability, and the spiral arrangement of the triangular blocks forms a continuous and uninterrupted flow guide line on the surface of the cable. No matter which angle the wind blows from, the airflow can immediately encounter the inclined surface of the triangular block and be guided away, achieving 360° dead angle protection, ensuring that the cable always maintains high stability under variable wind direction, and the continuous spiral structure not only suppresses vortex-induced vibration, but also helps to suppress high-order and large-amplitude vibration modes such as cable flutter, providing more comprehensive protection.

[0038] Each of the triangular blocks A 102 and the cable outer shell 101 is provided with an arc-shaped chamfer, and each of the triangular blocks B 103 and the cable outer shell 101 is provided with an arc-shaped chamfer.

[0039] The arc-shaped chamfer can further facilitate the smooth drainage of rainwater when it falls, and can reduce the accumulation of dust and impurities.

[0040] A wind-erosion-resistant and anti-aging cable preparation device, comprising a fixed column 201 and an auxiliary seat 202, the auxiliary seat 202 is provided with two, one auxiliary seat 202 is fixedly connected on the fixed column 201, the auxiliary seat 202 fixedly connected on the fixed column 201 is fixedly connected with a connecting rod 203, the other end of the connecting rod 203 is fixedly connected with the other auxiliary seat 202, the two auxiliary seats 202 are rotatably connected with a rotating part 401, the rotating part 401 is slidably connected with a supporting arc plate 402, two rectangular blocks are fixedly connected on each auxiliary seat 202, the plurality of rectangular blocks can be inserted into the side groove 104, the auxiliary seat 202 fixedly connected on the fixed column 201 is fixedly connected with a first motor, a gear is fixedly connected on the output shaft of the first motor, a gear ring is fixedly connected on the rotating part 401, and the gear is engaged with the gear ring.

[0041] The fixing post 201 and two auxiliary seats 202 are inserted into the inner circular groove 105, and multiple rectangular blocks are inserted into the two side grooves 104. Then, multiple triangular blocks A102 and multiple triangular blocks B103 are bonded and installed. During installation, the supporting arc plate 402 slides on the rotating part 401 to support the inner wall of the inner circular groove 105. Then, the bonding operation is performed at the support position of the supporting arc plate 402. This avoids the cable outer armor 101 from deforming due to its own material properties during the bonding process, which would result in triangular blocks A102 or B103 not making sufficient contact with the glue and thus failing to form a bonding effect. This prevents problems such as insufficient bonding area, discontinuous glue layer or gaps caused by local sinking of the cable outer armor. It ensures from the root that triangular blocks A102 and B103 can make full contact with the cable outer armor with the maximum area, laying a solid foundation for long-term wind erosion and aging resistance.

[0042] During the bonding process, the operable rotating part 401 rotates within a 360° range between the two auxiliary seats 202, thereby adjusting the support position of the support arc plate 402. This allows the support arc plate 402 to fully support the inner circular groove 105 in the circumferential direction, thus achieving full support for multiple triangular blocks A102 and multiple triangular blocks B103. This ensures that there is stable support inside the cable outer armor 101 during each bonding process, and that multiple triangular blocks A102 and multiple triangular blocks B103 can achieve a stable connection with the cable outer armor 101, thereby ensuring long-term use.

[0043] A robotic arm can periodically pull the cable outer armor 101, causing relative movement between the cable outer armor 101 and the fixed post 201. This allows the supporting arc plate 402 to support different positions inside the cable outer armor 101, achieving a comprehensive bonding support effect. The arrangement of multiple rectangular blocks and 404 ensures that the cable outer armor 101 will not rotate but will only move horizontally during the process of the robotic arm pulling the cable outer armor 101, thus facilitating the stable execution of subsequent bonding operations.

[0044] It also includes a rotating rod 301 connected to the fixed column 201, a transmission plate 302 fixedly connected to the rotating rod 301, a plurality of arc-shaped protrusions 305 fixedly connected to the transmission plate 302, a contact round rod 403 fixedly connected to the support arc plate 402, a first compression spring fixedly connected between the support arc plate 402 and the rotating part 401, and the plurality of arc-shaped protrusions 305 correspond one-to-one with the installation positions of the plurality of triangular blocks A102 and the plurality of triangular blocks B103.

[0045] When the rotating part 401 rotates, the elastic force provided by the first compression spring will always keep the contact rod 403 pressed against the transmission plate 302. As the rotating part 401 continues to rotate, the contact rod 403 will move in the circumferential direction of the transmission plate 302. During this process, whenever the contact rod 403 contacts the arc protrusion 305, the supporting arc plate 402 will abut against the inner wall of the inner circular groove 105, thereby completing the support effect. That is, the rotation of the rotating part 401 can automatically achieve both the moving support position and the sliding support effect. At the same time, when the moving cable outer armor 101 is pulled, it can also prevent the supporting arc plate 402 from pressing against the inner wall of the inner circular groove 105 and causing damage to the inner wall of the inner circular groove 105.

[0046] Each of the auxiliary seats 202 is connected to a plurality of movable arc plates 502.

[0047] After the cable outer armor 101 is moved using a robotic arm, multiple movable arc plates 502 can contact the inner wall of the inner circular groove 105. This allows the multiple movable arc plates 502 to support and fix the left and right sides of the cable outer armor 101 at the bonding position. Furthermore, by having multiple movable arc plates 502 contact the inner wall of the inner circular groove 105, the moved cable outer armor 101 is fixed, thus preventing the cable from shifting during the subsequent bonding process. Then, the supporting arc plates 402 are used to support the inner wall of the inner circular groove 105 in sequence, thereby successfully completing the subsequent bonding effect and ensuring the smooth progress of the bonding operation.

[0048] Multiple movable arc plates 502 contact the inner wall of the inner circular groove 105, like multiple wedges holding the cable outer armor 101 in place from the inside, thus providing a stable base for it before the bonding operation begins. This effectively prevents the cable outer armor 101 from moving uncontrollably due to external force or equipment vibration during the process of applying glue, placing and pressing the triangular blocks, creating a prerequisite for subsequent fine bonding.

[0049] On a macro scale, multiple movable arc plates 502 can provide rapid and wide-range initial fixation, ensuring that the entire cable segment does not shift during the bonding process. On a micro scale, the supporting arc plate 402 can provide precise radial support to specific bonding points, ensuring that the cable outer armor 101 will not be locally dented due to pressure at the moment of dispensing glue and pasting the triangular blocks. This ensures uniform glue layer and maximizes the bonding area, enabling the bonding operation to proceed stably and smoothly. It fundamentally ensures that multiple triangular blocks A102 and multiple triangular blocks B103 can form a firm connection with the cable outer armor 101, ensuring that the expected effect of the wind erosion and aging resistance design can be stably performed throughout the entire life cycle of the cable.

[0050] Each of the movable arc plates 502 is fixedly connected to a driven rod 501, and each driven rod 501 is fixedly connected to a sliding rod 503. The multiple sliding rods 503 are slidably connected to the two auxiliary seats 202 respectively.

[0051] By operating multiple sliding rods 503 to slide on two auxiliary seats 202 respectively, multiple movable arc plates 502 are slid, thereby retracting multiple movable arc plates 502 when moving the outer cable armor 101 to avoid damage to the inner wall of the inner circular groove 105. After the movement, multiple sliding rods 503 are slid again to press multiple movable arc plates 502 against the inner wall of the inner circular groove 105, thereby supporting and fixing the inner wall, so that the outer cable armor 101 can remain in the same position, thus ensuring that the subsequent bonding operation can be carried out smoothly.

[0052] It also includes a drive block 303 fixed to the rotating rod 301, a plurality of arc-shaped protrusions 304 fixed to the drive block 303, a second compression spring fixed between each slide rod 503 and the auxiliary seat 202, and a second motor capable of driving the rotating rod 301 fixed to the fixed column 201.

[0053] Multiple second compression springs cause multiple driven rods 501 to abut against the drive block 303. When multiple movable arc plates 502 need to be pushed out, the operating rod 301 is rotated, and the rotating rod 301 drives the drive block 303 to rotate, causing the drive block 303 to drive multiple arc surface protrusions 304 to rotate. The multiple arc surface protrusions 304 can push multiple driven rods 501, thereby causing multiple sliding rods 503 to slide, and thus pressing multiple movable arc plates 502 against the inner wall of the inner circular groove 105, completing the fixing effect of the inner circular groove 105.

[0054] When multiple movable arc plates 502 need to be retracted, the rotating rod 301 is rotated in the opposite direction to retract the multiple movable arc plates 502 and complete the effect of moving the inner circular groove 105.

[0055] The length of the inner circular groove 105 processed by this equipment is less than the overall length of the fixed column 201, thereby ensuring that the inner circular groove 105 can be fully processed during the subsequent bonding and molding operation. When actually installed, multiple inner circular grooves 105 can be snapped together for installation.

[0056] Both the drive block 303 and the arc-shaped protrusion 304 are arranged in two symmetrical positions with the center of the transmission plate 302 as the axis.

[0057] This setup ensures that when the rotating rod 301 rotates, it can smoothly drive the multiple driven rods 501 on the two auxiliary seats 202 to slide synchronously, thereby enabling the multiple moving arc plates 502 to extend or retract synchronously, thus completing the subsequent movement of the cable outer armor 101 and the fixation of the cable outer armor 101.

[0058] The aforementioned wind-erosion and aging-resistant cable preparation apparatus is used to prepare antibacterial plastics. The method includes the following steps:

[0059] Step 1: Place the fixing post 201 and auxiliary seat 202 assembly into the inner circular groove 105 of the cable outer armor 101, and ensure that the rectangular block is inserted into the side groove 104 to achieve circumferential positioning;

[0060] Step 2: The drive rod 301 drives the arc-shaped protrusion 304 on the drive block 303, which pushes the driven rod 501 to make multiple movable arc plates 502 press against the inner wall of the inner circular groove 105 to achieve axial fixation;

[0061] Step 3: Start the rotating part 401 to rotate. The contact rod 403 moves along the transmission plate 302 under the action of the first compression spring. It periodically contacts the arc-shaped protrusion 305, causing the supporting arc plate 402 to be pushed out radially, providing local adhesive support.

[0062] Step 4: At the position where the support arc plate 402 is raised, attach triangular block A102 and triangular block B103 to the inner wall of the cable outer armor 101 in sequence to ensure full contact;

[0063] Step 5: After completing one section of bonding, rotate the rotating rod 301 in the opposite direction to retract the moving arc plate 502, and use the robot arm to move the cable outer armor 101 axially to the next unprocessed section;

[0064] Step 6: Repeat steps 2 to 5 until the entire inner circular groove 105 is machined.
