Description

Technical Field

[0001] The present invention relates to the technical field of 5G cable production, and specifically to a cold-resistant and frost-resistant 5G cable and a production method thereof. Background Art

[0002] During use, the cable's own power comes from wind, which uses wind to rotate the outer shell and the guide plate on its outside as the main driving source. However, when the cable is used at high altitudes, thin ice is likely to appear on its surface in winter. When the ice freezes the guide plate and increases the friction, it is difficult for the wind to drive the guide plate to rotate. Once the guide plate rotates, frictional heat generation and subsequent snow removal operations cannot be performed. The Chinese patent announcement number is: CN114678171B, which discloses "A cold-resistant and frost-resistant 5G cable and its antifreeze method". The patent is provided with a stretching airbag. When the propulsion plate moves up and down to squeeze the rubber pad inside the air storage cavity, the internal space of the air storage cavity can be changed. When the space of the air storage cavity changes, the gas inside the stretching airbag can enter the interior of the air storage cavity through the drainage tube, thereby causing the stretching airbag to expand and contract. The contraction of the stretching airbag can pull the outer sheath inward, thereby causing the thin ice on the outer wall to break through the depression of the outer sheath surface. At the same time, when the stretching airbag between adjacent heat-conducting columns causes the outer sheath to be concave inward, the fit between the outer sheath and the arc surface of the outer end of the heat-conducting column can be further improved, thereby increasing the heat conduction effect between the heat-conducting column and the outer sheath.

[0003] The existing cold-resistant and frost-resistant 5G cables and their production methods have structural design defects. The use of stretching airbags to de-ice the cables will cause the cables themselves to have poor rigidity and be easily damaged by pulling. There is also the problem of how to control the temperature of the 5G cables to prevent the cables from overheating or overcooling. Summary of the Invention

[0016] A method for producing a cold-resistant and frost-resistant 5G cable comprises the following steps: Step 1: Wire core manufacturing: at room temperature, draw the copper rod into copper wire, heat and keep the copper wire warm, and then naturally cool the copper wire. Twist the copper wire by twisting multiple single wires to form a copper stranded wire. Use a traction machine to pull the copper stranded wire to the inside of an injection molding extruder and coat it with cross-linked polyethylene to complete the preparation of the copper conductor wire core. Similarly, the preparation of the six wire cores is completed. Step 2: Install the centering structure. Put plastic and rubber particles into the injection molding extruder.

The rubber tube is placed on the outside of the plastic structure. Multiple wire cores and hemp ropes are passed into the rubber tube in sequence.

Insert the through-tube into the outer surface of the sheath. Pull the elastic strip into the interior of the harness assembly for clamping and limiting. The two protective covers and the clamping block move relative to each other so that the sheath is fixedly installed near the through-tube. Fix the fixing assembly at the end faces of multiple elastic strips to complete the overall installation of the ice-breaking structure.

[0017] The present invention provides a cold-resistant and frost-resistant 5G cable and a production method thereof. It has the following beneficial effects: 1. This cold-resistant and frost-resistant 5G cable and its production method: the sheath between the two protective covers is affected by gravity and wind. In cold weather, the surface of the sheath and the protective cover are covered with ice. The wind blows the sheath to swing slowly. A single elastic strip absorbs elastic potential energy, which promotes the swing of multiple elastic strips. The cable harness assembly slides on the inner side of the circular guide rail to promote the breaking of the ice layer, replacing airbags and other structures to break ice, solving the problem that using stretching airbags to de-ice the cable will cause the cable itself to have poor rigidity and be easily damaged.

[0018] 2. This cold-resistant and frost-resistant 5G cable and its production method: the elastic strip is pulled away from the spring strip, the pitch of the spring strip increases, and the relative diameter of the spring strip decreases. At the beginning, the inner side of the spring strip is at a certain distance from the surface of the sheath. After the spring strip is stretched, it moves relative to the surface of the sheath and contacts it, so that the ice layer on the surface of the sheath is quickly broken. The expansion and contraction and torsion of the elastic strip promote the movement of the spring strip, and also promote the movement of the slider, thereby increasing the overall de-icing efficiency of the cable.

[0019] 3. This cold-resistant and frost-resistant 5G cable and its production method, in cold weather, introduces room-temperature gas into the interior of the cable through a curved pipe, and the heat of the wire core is transferred to the flowing room-temperature gas. As the gas flows, the temperature is transferred to the sheath. The increase in the sheath temperature helps to break the ice layer. With the help of wind force, the sheath swings, and the wire harness assembly and scraping assembly promote the breaking of the ice layer on the entire cable. Combined with the increase in the sheath temperature, this solves the problem of how to control the temperature of the 5G cable to prevent the cable from overheating or overcooling.

[0020] 4. This cold-resistant and frost-resistant 5G cable and its production method, silicone is introduced into the interior of the rubber tube through the glue injection hole. The silicone allows multiple cores and hemp ropes to be quickly positioned, and the hemp ropes prevent the cores from being dislocated when squeezed. The thermal wire quickly transfers the heat of the cores to the outside of the rubber tube. When cooling gas flows on the surface of the spring sheet, the heat of the cores is quickly taken away to prevent the cable from overheating. In cold weather, the gas flowing from the spring sheet helps transfer heat to the sheath, preventing the cable from overheating while fully utilizing the heat of the cores.

[0021] 5. This cold-resistant and frost-resistant 5G cable and its production method: when the two oppositely arranged connecting rings are pulled apart, the pitch of the spring bar increases and the diameter decreases, the sliding body slides toward the axis in the inner groove, and the ice layer deposited on the surface of the sheath is easily broken by the squeezing of the spring bar. At the same time, since the heat of the wire core is transferred to the spring sheet through the heat of the wire core, the temperature of the sheath surface increases, which prevents the material from aging and brittleness at low temperatures, thereby effectively improving the cold and heat resistance of the cable.

[0026] During use, the 5G cable is fixedly installed on the top of the insulator 3, and the fixing plate 2 fixes the bottom of the insulator 3 on the top of the support seat 1. The support seat 1 is set above the surface of the tower. The insulator 3 provides insulation and protection support for the ice-breaking mechanism 4 as a whole. The rubber sheath 5 covers the outer surface of the heat transfer mechanism 6. The two upper and lower clamping blocks 45 move relative to each other and are fastened by bolts. The inner side of the clamping block 45 is pressed and positioned against the outer surface of the sheath 5. The sheath 5 between the two protective covers 43 is affected by gravity and wind. In cold weather, the surfaces of the sheath 5 and the protective cover 43 are covered with ice. The wind blows the sheath 5 to swing slowly. A single elastic strip 47 absorbs elastic potential energy and promotes the swing of multiple elastic strips 47. The wire harness assembly 46 slides on the inner side of the circumferential guide rail 42 to promote the breaking of the ice layer, replacing airbags and other structures to break ice, and solves the problem that using stretching airbags to de-ice cables will cause the cable itself to have poor rigidity and be easily damaged.

[0027] Second embodiment: Figure 4-Figure 7 As shown, the harness assembly 46 includes a slider 461, which is slidably mounted on the inner side of the circumferential guide rail 42, and the surface of the slider 461 is rotatably connected to the ball 462, and the surface of the ball 462 is in close contact with the inner side of the circumferential guide rail 42.

The scraping assembly 48 includes a connecting ring 481, the side of which is fixedly mounted on the end of the elastic strip 47 away from the friction wheel 466, and an inner groove 482 is provided on the side of the connecting ring 481 away from the elastic strip 47. The scraping assembly 48 also includes a sliding body 483, the surface of which is slidably mounted on the connecting ring 481 near the inner groove 482, and the surface of the sliding body 483 is fixedly connected to a spring strip 484.

[0028] When in use, the inner side of the circumferential guide rail 42 is provided with a sliding groove, and the ball 462 rolls inside the sliding groove, and the sliding friction is replaced by rolling friction, so that the slider 461 is easier to move on the inner side of the circumferential guide rail 42, and the ice layer near the protective cover 43 is easier to break. The torsion of the spring bar 484 promotes the movement of the slider 461 to break the ice, the sleeve 463 slides and supports the elastic bar 47, and the motor 465 drives the friction wheel 466 to rotate, and the friction wheel 466 uses friction to make the elastic bar 47 close to the circumferential guide rail. 42 moves, the elastic strip 47 is pulled away from the spring strip 484, the pitch of the spring strip 484 increases, and the relative diameter of the spring strip 484 decreases. At the beginning, the inner side of the spring strip 484 is at a certain distance from the surface of the sheath 5. After the spring strip 484 is stretched, it moves relative to the surface of the sheath 5 and contacts, so that the ice layer on the surface of the sheath 5 is quickly broken. The expansion and contraction and torsion of the elastic strip 47 promote the movement of the spring strip 484, and also promote the movement of the slider 461, thereby increasing the overall deicing efficiency of the cable.

[0029] The third embodiment: Figure 4 、 Figure 8 As shown, the inner side surface of the circumferential guide rail 42 is slidably connected to a harness assembly 46, and the inner side surface of the harness assembly 46 is frictionally connected to an elastic strip 47, and the end of the elastic strip 47 away from the harness assembly 46 is fixedly connected to a scraper assembly 48. A pressing block 45 is frictionally pressed on the surface of the sheath 5 near the through-tube 41, and a protective cover 43 is fixedly connected to the surface of the pressing block 45. An arc-shaped hole 44 is provided on the side of the protective cover 43 near the pressing block 45. The harness assembly 46 is used for telescopic adjustment of the elastic strip 47, and the scraper assembly 48 is used for scraping and breaking thin ice on the surface of the sheath 5. The heat transfer mechanism 6 includes a heat shrink tube 61, which is fixedly installed on the inner side of the sheath 5. The inner side of the heat shrink tube 61 is fixedly connected to a flow guide component 62, the inner side of the flow guide component 62 is fixedly connected to a centering component 63, and the inner side of the centering component 63 is fixedly connected to a hemp rope 64. The heat transfer mechanism 6 also includes an embedded tube 65, which is fixedly installed on the surface of the heat shrink tube 61. The inner side of the embedded tube 65 is fixedly connected to a bent tube 66, and the upper position of the surface of the bent tube 66 is fixedly connected to a fixing seat 67.

[0030] When in use, multiple cores 7 are positioned and blocked by the centering component 63, and the guide component 62 is arranged between the centering component 63 and the heat shrink tube 61. The guide component 62 forms a spiral airflow channel structure, and the elbow 66 introduces the cooling gas into the interior of the airflow channel. As the cooling gas is introduced and discharged, the heat of the core 7 is promptly discharged through the centering component 63 and the cooling gas, thereby preventing the cable from overheating. The connecting pipe 8 is used to supply gas to the multiple elbows 66, which is convenient for controlling multiple cables. In cold weather, normal temperature gas is introduced into the interior of the cable through the elbow 66, and the heat of the core 7 is transferred to the flowing normal temperature gas. As the gas flows, the temperature is transferred to the sheath 5. The increase in temperature of the sheath 5 helps to break the ice layer. The sheath 5 is swung by the wind, and the wire bundling component 46 and the scraping component 48 promote the breaking of the ice layer of the entire cable. Combined with the increase in temperature of the sheath 5, the problem of how to control the temperature of the 5G cable to prevent the cable from overheating or overcooling is solved.

[0031] Fourth embodiment: Figure 6 、 Figure 7 、 Figure 8 As shown, the flow guide assembly 62 includes a spring sheet 621, the outer surface of which is fixedly mounted on the inner side of the heat shrink tube 61. A plastic strip 622 is passed through and fixedly connected to the inner side of the spring sheet 621. A rubber strip 623 is fixedly connected to the inner side of the spring sheet 621. The centering assembly 63 includes a rubber tube 631. A hot melt adhesive strip 632 is fixedly connected to the outer surface of the rubber tube 631.

The centering assembly 63 further includes a plastic plate 635 . The surface of the plastic plate 635 is fixedly mounted on the inner side of the rubber tube 631 . A plastic tube 636 is fixedly connected to the side of the plastic plate 635 away from the rubber tube 631 .

[0032] When in use, the wire core 7 inside the 5G cable will emit heat. When the external temperature is too high, the heat of the wire core 7 will cause the heat to be unable to be discharged and the cable as a whole will overheat. In this device, the soft embedded tube 65 makes the elbow 66 and the sheath 5 sealed. The heat-conducting wire 634 is tightly fixed to the surface of the rubber tube 631 by threading. The connection of the heat-conducting wire 634 allows the heat inside and outside the rubber tube 631 to be quickly transferred. The hot melt adhesive strip 632 is quickly connected to the rubber strip 623 when heated, and the adhesive is injected into the rubber strip 623 through the adhesive injection hole 633. Silicone is passed into the interior of the rubber tube 631. The silicone allows multiple cores 7 and the hemp rope 64 to be quickly positioned. The hemp rope 64 prevents the cores 7 from being dislocated when squeezed. The thermal wire 634 quickly transfers the heat of the cores 7 to the outside of the rubber tube 631. When cooling gas flows on the surface of the spring piece 621, the heat of the cores 7 is quickly taken away to prevent the cable from overheating. In cold weather, the gas flowing through the spring piece 621 helps to transfer heat to the sheath 5, preventing the cable from overheating while making full use of the heat of the cores 7.

[0033] Fifth embodiment: Figure 7 、 Figure 9 、 Figure 10 As shown, the side of the connecting ring 481 is fixedly mounted on the end of the elastic strip 47 away from the friction wheel 466. The side of the connecting ring 481 away from the elastic strip 47 is provided with an inner groove 482. The scraping assembly 48 also includes a sliding body 483. The surface of the sliding body 483 is slidably mounted on the connecting ring 481 near the inner groove 482. The surface of the sliding body 483 is fixedly connected to the spring strip 484. The outer surface of the spring sheet 621 is fixedly mounted on the inner side of the heat shrink tube 61, the inner side of the spring sheet 621 is penetrated by and fixedly connected with a plastic strip 622, the inner side of the spring sheet 621 is fixedly connected with a rubber strip 623, the centering assembly 63 includes a rubber tube 631, the outer surface of the rubber tube 631 is fixedly connected with a hot melt adhesive strip 632, the surface of the rubber tube 631 is provided with an injection hole 633, and the surface of the rubber tube 631 is fixedly connected with a thermal wire 634.

[0034] When in use, the inner side of the spring strip 484 contacts the surface of the sheath 5. When the surface of the sheath 5 is covered with ice, the material is easily corroded and aged. In this device, the position of the sheath 5 away from the circumferential guide rail 42 is easily pushed and swung by the wind. Through the elastic absorption and release of the local elastic strip 47, the slider 461 easily slides on the inner side of the circumferential guide rail 42, thereby promoting the breaking of the ice layer around the protective cover 43. Multiple plastic strips 622 penetrate the spring sheet 621. The support of the spring sheet 621 and the plastic strip 622 makes the electric The overall structure of the cable has a stronger ability to resist deformation. When the two oppositely arranged connecting rings 481 are pulled apart, the pitch of the spring bar 484 increases and the diameter decreases. The sliding body 483 slides toward the axis in the position of the inner groove 482. The ice layer deposited on the surface of the sheath 5 is easily broken under the squeezing of the spring bar 484. At the same time, since the heat of the core 7 is transferred to the spring piece 621 through the heat of the core 7, the temperature of the surface of the sheath 5 increases, which prevents the material from aging and brittleness at low temperatures, thereby effectively improving the cold and heat resistance of the cable.

Twist the copper wire by twisting multiple single wires to form a copper stranded wire. Use a traction machine to pull the copper stranded wire to the inside of an injection molding extruder and coat it with cross-linked polyethylene to complete the preparation of the copper conductor core 7. Similarly, the preparation of six wire cores 7 is completed. Step 2: Install the centering structure. Put plastic and rubber granules into the injection molding extruder. The hot-melt plastic is formed into a plastic plate 635 and a plastic tube 636 through a die. The heat-conducting wire 634 is passed through the rubber tube 631 in sequence.
