Description

Technical Field

[0001] This invention belongs to the technical field of high-voltage cable processing, specifically, it relates to a high-voltage cable enameling processing system. Background Technology

[0002] The core defects of pre-coating cleaning of high-voltage cables are concentrated in two main aspects: incomplete drying leading to water stains and insufficient primary cleaning capacity. The combination of these two will seriously damage the adhesion, uniformity, and insulation reliability of the coating layer, ultimately affecting the long-term operational safety of high-voltage cables.

[0003] The dehydration and drying processes after cleaning fail, and common methods such as brushes, ordinary air knives, and hot air at normal pressure are insufficient to completely remove capillary water, crevice water, and adsorbed water from the surface of high-voltage cables. If the ambient humidity is high or the drying temperature / wind speed is insufficient, the moisture will not evaporate completely, and the residual moisture will form water stains after drying. Water stains cause uneven local temperature during the curing of the paint layer, forming internal stress and microcracks, reducing the insulation strength.

[0004] Existing cleaning equipment relies solely on primary cleaning methods such as high-pressure water jetting, solvent wiping, or dry purging, which are insufficient to handle complex contaminants. The firmly adsorbed layer formed by these contaminants on metal surfaces is difficult to remove in a single cleaning cycle. High-voltage cables require extremely high surface cleanliness; residual contaminants and water stains can create conductive channels or localized high-field strength points under high electric fields, inducing faults such as electric treeing and partial discharge, threatening operational safety. Primary cleaning is difficult to adapt to high-voltage cables of different specifications and materials; fixed cleaning parameters result in over-cleaning of some products and under-cleaning of others. Summary of the Invention

[0005] This invention provides a high-voltage cable enameling processing system to remove impurities from the surface of high-voltage cables and effectively remove cleaning fluid from the surface of high-voltage cables, avoiding water stains and improving the adhesion, uniformity and insulation of the enameling layer.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A high-voltage cable enameling processing system includes a primary multi-line co-washing mechanism, a secondary multi-line individual washing mechanism, a drying mechanism, and a multi-stage enameling mechanism arranged sequentially along the processing direction of the high-voltage cable. The secondary multi-line individual washing mechanism and the primary multi-line co-washing mechanism are connected. Multiple high-voltage cables arranged side by side pass through the primary multi-line co-washing mechanism, the secondary multi-line individual washing mechanism, the drying mechanism, and the multi-stage enameling mechanism in sequence through a turning mechanism. The enameled high-voltage cables enter the drying chamber for drying.

[0007] A further technical solution is that the primary multi-line co-washing mechanism includes a washing tank set on the ground, multiple high-voltage cables passing through the washing tank in parallel and submerged below the surface of the washing liquid in the washing tank, and a plate filter partition is detachably installed near the secondary multi-line independent washing mechanism in the washing tank. The inner cavity of the washing tank is divided into a primary washing chamber and a secondary washing chamber by the plate filter partition, and the secondary multi-line independent washing mechanism is set above the secondary washing chamber.

[0008] A further technical solution is that mounting rails are symmetrically constructed on both sides of the inner wall of the cleaning tank, and the two sides of the plate filter separator are slidably connected to the cleaning tank via the two mounting rails. Multiple conductive sleeves are spaced apart at the lower part of the plate filter separator along the width direction of the cleaning tank, and each high-voltage cable passes through the plate filter separator through the corresponding conductive sleeve.

[0009] A further technical solution is that the secondary multi-line independent washing mechanism includes multiple single-line washing units arranged side by side. The lower part of each single-line washing unit is detachably installed on a transfer beam. The transfer beam is installed on the primary multi-line co-washing mechanism, and the lower end of the single-line washing unit extends into the primary multi-line co-washing mechanism. Multiple high-voltage cables pass through the multiple single-line washing units one by one. The liquid inlet end of each single-line washing unit is connected to the outlet end of the pressure pump through a connector pipe on the liquid inlet manifold. The inlet end of the pressure pump is connected to the primary multi-line co-washing mechanism through a filter.

[0010] A further technical solution is that the single-line cleaning unit includes a vertical cleaning pipe detachably connected to the transfer beam. The lower end of the vertical cleaning pipe extends into the primary multi-line co-washing mechanism. An inlet branch pipe is connected to the upper peripheral wall of the vertical cleaning pipe. An inlet control valve is installed on the inlet branch pipe. The high-voltage cable passes through the vertical cleaning pipe from bottom to top.

[0011] A further technical solution is that a liquid distribution cylinder is coaxially arranged above the vertical cleaning pipe, the lower diameter of the liquid distribution cylinder gradually decreases downward in the vertical direction, and the small diameter end of the liquid distribution cylinder is connected to the upper end of the vertical cleaning pipe, and the liquid inlet branch pipe is eccentrically connected to the peripheral wall of the liquid distribution cylinder.

[0012] A further technical solution is that the upper end of the vertical cleaning tube is movably inserted into the vertical movable tube, and a liquid stain removal core is provided between the vertical cleaning tube and the vertical movable tube, with the high-voltage cable passing through the liquid stain removal core.

[0013] A further technical solution is that multiple through-holes are provided on the upper peripheral wall of the vertical movable tube and at the upper end of the liquid stain removal core. A liquid guiding sleeve is fitted over the vertical movable tube, and each through-hole is located inside the liquid guiding sleeve. A discharge pipe is connected to the liquid guiding sleeve, and the discharge pipe is connected to the primary multi-line co-washing mechanism. The upper end of each vertical movable tube is detachably connected to a movable seat, and the movable seat is connected to the vertical drive component.

[0014] A further technical solution is that the multi-stage enameling mechanism includes multiple enameling units arranged at vertical intervals. The two sides of the multiple enameling units are respectively installed on two vertical mounting rails, and the paint inlet branch pipe of each enameling unit is connected to the paint inlet main pipe, and the paint outlet branch pipe of each enameling unit is connected to the paint outlet main pipe. A paint inlet control valve is installed on the paint inlet joint of the paint inlet main pipe, and a paint outlet control valve is installed on the paint outlet joint of the paint outlet main pipe. The paint outlet joint is connected to the inlet end of the intermediate tank, the outlet end of the intermediate tank is connected to the inlet end of the circulating pump, and the outlet end of the circulating pump is connected to the paint inlet joint.

[0015] A further technical solution is that the enameling unit includes a transverse assembly with both ends mounted on two vertical mounting rails. Multiple tapered paint grooves are spaced apart along the length of the upper end face of the transverse assembly. The lower end of each tapered paint groove is connected to a paint discharge sleeve through a wire hole. The paint discharge sleeve is constructed on the lower end face of the transverse assembly. The paint inlet branch pipe is connected to the tapered paint groove, and the paint discharge branch pipe is connected to the paint discharge sleeve.

[0016] The technological advancements achieved by this invention compared to existing technologies, due to the adoption of the aforementioned structure, are as follows: This invention uses a primary multi-line co-washing mechanism to accommodate multiple high-voltage cables for parallel immersion cleaning, which can complete the initial removal of heavy contaminants such as rolling oil, large-area oxide scale, and dust from the surface of multiple high-voltage cables in one go, solving the problems of low single-cable processing efficiency and uneven batch cleaning in traditional primary cleaning.

[0017] The secondary multi-line independent cleaning unit cleans multiple high-voltage cables simultaneously and independently, achieving precise cleaning of each cable. Compared to the insufficient cleaning of blind spots such as high-voltage cable grooves and stranding gaps by traditional primary cleaning, the secondary multi-line independent cleaning unit thoroughly removes residual impurities after the primary cleaning of high-voltage cables, solving the industry problem of complex contaminants being difficult to remove in a single pass.

[0018] After cleaning, the high-voltage cable goes directly into the drying unit. Compared with the inefficiency of traditional atmospheric pressure hot air drying, the dedicated drying unit can provide a stable temperature field and quickly evaporate the residual trace moisture. Furthermore, the high-voltage cable after enameling goes into the drying chamber again for drying, which not only ensures the curing quality of the paint layer, but also further avoids the hidden danger of residual moisture combining with the paint layer to form pinholes and shrinkage cavities, completely eliminating the impact of water stains on the quality of enameling.

[0019] Both the primary multi-line co-washing mechanism and the secondary multi-line independent washing mechanism support the parallel and synchronous processing of multiple high-voltage cables. The turning mechanism ensures the smooth transfer of high-voltage cables between processes, eliminating the need for individual cable switching and significantly improving the efficiency of batch production. This solves the problems of long single-cable processing cycles and low capacity in traditional primary cleaning, making it particularly suitable for large-scale high-voltage cable processing scenarios. The mechanisms are connected in series along the high-voltage cable processing direction. The high-voltage cables flow directly to the next process via the turning mechanism, eliminating the need for additional transfer or secondary positioning. This avoids the risk of new contaminants adhering to the surface of the high-voltage cables during intermediate processes and reduces damage to the high-voltage cables caused by transfer, thereby improving the product qualification rate.

[0020] In summary, this invention, through its integrated design of multi-stage closed-loop cleaning for contamination removal, liquid stain removal, precise drying, and graded enameling, fundamentally solves the core defects of traditional high-voltage cable pre-enameling cleaning, such as incomplete first-stage contamination removal and water stain residue affecting enameling quality. It also considers production efficiency, environmental friendliness, and process adaptability, ultimately achieving a comprehensive improvement in the adhesion, uniformity, and insulation reliability of the high-voltage cable enameling layer. This provides crucial assurance for the safe and stable operation of high-voltage cables, and is particularly suitable for large-scale, multi-specification high-voltage cable industrial processing scenarios.

Detailed Implementation

[0024] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0025] This invention discloses a high-voltage cable enameling processing system, such as... Figures 1-13As shown, the system includes a primary multi-line co-washing mechanism 100, a secondary multi-line independent washing mechanism 200, a drying mechanism 300, and a multi-stage enameling mechanism 400 arranged sequentially along the processing direction of the high-voltage cable 600. The secondary multi-line independent washing mechanism 200 and the primary multi-line co-washing mechanism 100 are connected. Multiple high-voltage cables 600 arranged side by side pass through the primary multi-line co-washing mechanism 100, the secondary multi-line independent washing mechanism 200, the drying mechanism 300, and the multi-stage enameling mechanism 400 in sequence through a turning mechanism. The enameled high-voltage cables 600 enter the drying chamber for drying.

[0026] This invention uses a primary multi-line co-washing mechanism 100 to accommodate multiple high-voltage cables 600 for parallel immersion cleaning. It can complete the initial removal of heavy contaminants such as rolled oil stains, large-area oxide scale, and dust from the surface of multiple high-voltage cables 600 in one go, solving the problems of low single-cable processing efficiency and uneven batch cleaning in traditional primary cleaning.

[0027] The secondary multi-line independent cleaning unit 200 simultaneously and independently cleans multiple high-voltage cables 600, achieving precise cleaning of each cable individually. Compared to the insufficient cleaning of blind spots such as grooves and stranding gaps in traditional primary cleaning, the secondary multi-line independent cleaning unit 200 thoroughly removes residual impurities after the primary cleaning of the high-voltage cables 600, solving the industry problem of complex contaminants being difficult to remove in a single pass.

[0028] After cleaning, the high-voltage cable 600 directly enters the drying unit 300. Compared with the inefficiency of traditional atmospheric pressure hot air drying, the dedicated drying unit 300 can provide a stable temperature field and quickly evaporate the residual trace moisture. Furthermore, the high-voltage cable 600 after enameling enters the drying chamber again for drying, which not only ensures the curing quality of the paint layer, but also further avoids the hidden danger of residual moisture combining with the paint layer to form pinholes and shrinkage cavities, completely eliminating the impact of water stains on the quality of enameling.

[0029] Both the primary multi-line co-washing mechanism 100 and the secondary multi-line independent washing mechanism 200 support the parallel and synchronous processing of multiple high-voltage cables 600. The turning mechanism enables the smooth transfer of high-voltage cables 600 between processes, eliminating the need for individual cable switching and significantly improving the efficiency of batch production. This solves the problems of long single-cable processing cycles and low capacity in traditional primary cleaning, making it particularly suitable for large-scale high-voltage cable 600 processing scenarios. The mechanisms are connected in series along the processing direction of the high-voltage cables 600. The high-voltage cables 600 flow directly to the next process via the turning mechanism without additional transfer or secondary positioning, avoiding the risk of new contaminants adhering to the surface of the high-voltage cables 600 during intermediate stages. It also reduces damage to the high-voltage cables 600 caused by transfer, improving the product qualification rate.

[0030] In summary, this invention, through its integrated design of multi-stage closed-loop cleaning for contamination removal, liquid stain removal, precise drying, and graded enameling, fundamentally solves the core defects of traditional high-voltage cable 600: incomplete first-stage cleaning before enameling and water residue affecting enameling quality. Simultaneously, it considers production efficiency, environmental friendliness, and process adaptability, ultimately achieving a comprehensive improvement in the adhesion, uniformity, and insulation reliability of the high-voltage cable 600 enameling layer. This provides crucial assurance for the safe and stable operation of high-voltage cables 600, and is particularly suitable for large-scale, multi-specification industrial processing of high-voltage cables 600.

[0031] As a preferred embodiment of the present invention, such as Figures 1-3 As shown, the steering mechanism includes a first steering wheel set 500, a second steering wheel set 501, and a third steering wheel set 502 installed at the primary multi-line co-washing mechanism 100. A fourth steering wheel set 503 is provided between the outlet end of the secondary multi-line independent washing mechanism 200 and the inlet end of the drying mechanism 300. A fifth steering wheel set 504 is provided between the outlet end of the drying mechanism 300 and the inlet end of the multi-stage enameling mechanism 400.

[0032] As a preferred embodiment of the present invention, such as Figures 1-4 As shown, the primary multi-line co-washing mechanism 100 includes a washing tank 101 set on the ground. A first steering wheel set 500, a second steering wheel set 501, and a third steering wheel set 502 are spaced apart along the conveying direction of the high-voltage cable 600. The first steering wheel set 500 is located at the upper part of one end of the washing tank 101, while the second and third steering wheel sets 501 and 502 are both installed inside the washing tank 101. Multiple high-voltage cables 600 pass side-by-side through the washing tank 101 and are submerged below the surface of the cleaning liquid within the washing tank 101. A plate-type filter separator 102 is detachably installed in the washing tank 101 near the secondary multi-line independent washing mechanism 200. This plate-type filter separator 102 is located between the second and third steering wheel sets 501 and 502. The inner cavity of the washing tank 101 is divided into a primary washing chamber 104 and a secondary washing chamber 105 by the plate-type filter separator 102. The secondary multi-line independent washing mechanism 200 is located above the secondary washing chamber 105. In this embodiment, mounting rails are symmetrically constructed on both sides of the inner wall of the cleaning tank 101. The two sides of the plate filter separator 102 are slidably connected to the cleaning tank 101 via two mounting rails. Multiple conductive sleeves 103 are spaced apart at the lower part of the plate filter separator 102 along the width direction of the cleaning tank 101. Each high-voltage cable 600 passes through the plate filter separator 102 through the corresponding conductive sleeve 103.

[0033] In this embodiment, the cleaning tank 101 supports multiple high-voltage cables 600 passing side-by-side and being completely immersed in the cleaning fluid. Combined with the guiding transmission of the first steering wheel set 500, the second steering wheel set 501, and the third steering wheel set 502, it enables multiple high-voltage cables 600 to undergo simultaneous primary cleaning, completely changing the inefficient traditional single-cable sequential cleaning method. Compared to single-cable cleaning, this design significantly increases the throughput of batch production, especially suitable for large-scale high-voltage cable 600 processing scenarios, and significantly reduces the processing time cost per unit product. The layout design of the first steering wheel set 500 (upper part of one end of the cleaning tank 101), the second steering wheel set 501, and the third steering wheel set 502 (inside the cleaning tank 101) allows the high-voltage cables 600 to pass through the cleaning tank 101 in an S-shaped path and be fully immersed in the cleaning fluid, extending the contact time between the high-voltage cables 600 and the cleaning fluid. This optimized approach avoids the problem of insufficient contaminant removal caused by shallow immersion cleaning, ensuring that stubborn contaminants such as heavy oil stains and large areas of oxide scale can be effectively loosened and removed in the initial stage, laying a clean foundation for subsequent secondary cleaning.

[0034] In this embodiment, the plate filter separator 102 divides the inner cavity of the cleaning tank 101 into a primary cleaning chamber 104 (front end) and a secondary cleaning chamber 105 (rear end), and the plate filter separator 102 is located between the second steering wheel assembly 501 and the third steering wheel assembly 502. The high-voltage cable 600 first undergoes heavy contamination removal in the primary cleaning chamber 104, and then enters the secondary cleaning chamber 105 through the plate filter separator 102. The removed contaminants are confined to the primary cleaning chamber 104 and cannot flow back to the secondary cleaning chamber 105 with the cleaning fluid, thus preventing contamination of the initially cleaned high-voltage cable 600. This design solves the core problem of contaminant circulation and adhesion in traditional single-tank cleaning, ensuring that the cleaning fluid maintains a high level of cleanliness in the secondary cleaning chamber 105, providing excellent preconditions for subsequent secondary multi-line independent cleaning. Multiple conductive sleeves 103 at the lower part of the plate filter separator 102 correspond one-to-one with the high-voltage cable 600, and each high-voltage cable 600 passes through the plate filter separator 102 through a dedicated conductive sleeve 103. This design not only achieves the orderly arrangement of multiple high-voltage cables 600 in the cleaning tank 101, avoiding surface damage caused by the high-voltage cables 600 tangling and rubbing against each other, but also prevents contaminants in the primary cleaning chamber 104 from entering the secondary cleaning chamber 105 through the gaps between the high-voltage cables 600 through the sealing and guiding function of the conductive sleeve 103, further enhancing the isolation effect of the zoned filtration and ensuring the cleaning consistency of each high-voltage cable 600.

[0035] In this embodiment, the symmetrical mounting rails on the inner wall of the cleaning tank 101 are slidably connected to the plate filter separators 102, allowing the plate filter separators 102 to be quickly pulled out and removed along the mounting rails. Compared to fixed-connection separator structures, this design allows for the removal, cleaning, or replacement of the plate filter separators 102 without the need for complex tools, significantly reducing equipment downtime for maintenance. It is particularly suitable for efficient cleaning of filters after long-term clogging, ensuring continuous operation of the production line. The guide sleeves 103 are spaced apart along the width of the cleaning tank 101. The specifications and quantity of the guide sleeves 103 can be flexibly adjusted according to the diameter and number of high-voltage cables 600, enabling the primary multi-line co-washing mechanism 100 to adapt to the processing requirements of high-voltage cables 600 with different cross-sections and materials. Compared to traditional cleaning equipment with fixed apertures, this design improves the versatility of the equipment and reduces equipment modification costs caused by product specification changes. The high-voltage cable 600 is fully submerged below the surface of the cleaning solution. Compared with traditional spray or wiping cleaning, this method can cover the grooves and strand gaps on the surface of the high-voltage cable 600, which are prone to forming blind spots. This allows the cleaning solution to fully penetrate and remove hidden contaminants, solving the problem of surface cleanliness but internal residue in traditional primary cleaning. This provides a cleaner conductor surface for the subsequent enameling process.

[0036] In summary, the primary multi-line co-washing mechanism 100 of this embodiment, through its integrated design of multi-line parallel immersion washing, zoned filtration to prevent backflow, convenient disassembly and maintenance, and precise guided transmission, not only breaks through the efficiency bottleneck of traditional primary cleaning, but also ensures cleaning cleanliness through zoned isolation and full immersion design, while taking into account the equipment's versatility and ease of maintenance. Its core value lies in providing an efficient, clean, stable, and low-cost batch pretreatment solution for the cleaning process before enameling of high-voltage cables 600, laying a key foundation for subsequent secondary multi-line independent washing and enameling processes, and ultimately helping to improve the overall product enameling quality and production efficiency.

[0037] As a preferred embodiment of the present invention, such as Figures 5-8As shown, the secondary multi-line independent washing mechanism 200 includes multiple single-line washing units 201 arranged side by side. The lower part of each single-line washing unit 201 is detachably mounted on a transfer beam 202, which is mounted on the primary multi-line co-washing mechanism 100. The lower end of each single-line washing unit 201 extends into the primary multi-line co-washing mechanism 100. Multiple high-voltage cables 600 pass through the multiple single-line washing units 201. The liquid inlet of each single-line washing unit 201 is connected to the outlet of a pressure pump through a connector pipe 206 on the liquid inlet manifold 203. The inlet of the pressure pump is connected to the primary multi-line co-washing mechanism 100 through a filter. That is, a liquid outlet pipe 106 is connected to the washing tank 101. The liquid outlet pipe 106 is connected to the secondary washing chamber 105 and the inlet of the pressure pump. In this embodiment, the single-line cleaning unit 201 includes a vertical cleaning pipe 2012 detachably connected to the adapter beam 202. The lower end of the vertical cleaning pipe 2012 extends into the secondary cleaning chamber 105 of the primary multi-line co-washing mechanism 100. An inlet branch pipe 204 is connected to the upper peripheral wall of the vertical cleaning pipe 2012. An inlet control valve 205 is installed on the inlet branch pipe 204. The high-voltage cable 600 passes through the vertical cleaning pipe 2012 from bottom to top in the vertical direction.

[0038] In this embodiment, the secondary multi-line independent washing mechanism 200 adopts a one-to-one design with multiple single-line cleaning units 201 corresponding to a single high-voltage cable 600. Each high-voltage cable 600 passes through an independent single-line cleaning unit 201, completely eliminating the cross-contamination problem caused by contaminants from one high-voltage cable 600 adhering to another in traditional multi-line co-washing. Each single-line cleaning unit 201 cleans only the surface of a single high-voltage cable 600, ensuring consistent cleaning results for each cable and improving the quality stability of mass production. Each single-line cleaning unit 201 draws clean cleaning fluid (filtered of impurities) from the secondary cleaning chamber 105 of the primary multi-line co-washing mechanism 100 using a pressure pump and delivers it under high pressure through the inlet branch pipe 204 to the vertical cleaning pipe 2012. When the high-voltage cable 600 passes vertically from bottom to top through the vertical cleaning pipe 2012, the high-pressure cleaning fluid can directionally flush the surface of the high-voltage cable 600, precisely removing the complex contaminants remaining after the primary cleaning. It can especially penetrate into blind spots such as the twisted seams and grooves of the high-voltage cable 600, which are difficult to reach with traditional cleaning methods, thus solving the core defect of primary cleaning: surface cleanliness but internal residue. Each single-line cleaning unit 201 has an inlet control valve 205 installed on its inlet branch pipe 204, which can independently adjust the cleaning fluid pressure and flow rate of each single-line cleaning unit 201 according to the material, diameter, and surface contamination degree of the high-voltage cable 600. For example, the flow rate can be increased for large-section high-voltage cables 600 with heavy surface contamination, while the pressure can be reduced for softer high-voltage cables 600 to avoid damage. Compared to the fixed parameters and poor adaptability of traditional primary cleaning, this significantly improves the equipment's adaptability to different specifications of high-voltage cables 600.

[0039] In this embodiment, the inlet of the pressure pump is connected to the secondary cleaning chamber 105 of the primary multi-line co-washing mechanism 100 via a filter. The cleaning fluid is filtered to remove impurities before being delivered to the single-line cleaning unit 201, preventing contaminants from flowing back to the surface of the high-voltage cable 600 with the cleaning fluid. This ensures that the cleaning fluid is in a highly clean state with each rinse, further improving the cleaning effect. At the same time, the recycling of the cleaning fluid significantly reduces the consumption of new fluid, lowers wastewater discharge and treatment costs, and meets the requirements of environmentally friendly production. The pressure pump draws cleaning fluid from the secondary cleaning chamber 105 through the outlet pipe 106. The secondary cleaning chamber 105 is isolated from the primary cleaning chamber 104 by a plate filter separator 102. The cleaning fluid inside the secondary cleaning chamber 105 is cleaner than that in the primary cleaning chamber 104, eliminating the need for an additional independent storage tank. This simplifies the equipment structure and prevents the contaminated cleaning fluid in the primary cleaning chamber 104 from affecting the secondary single-line washing effect, forming a closed-loop cleaning logic of primary removal of heavy contaminants, secondary extraction of clean fluid, and high-pressure precision washing.

[0040] The lower part of the single-line cleaning unit 201 is detachably mounted on the adapter beam 202, facilitating the daily disassembly, cleaning, or replacement of individual single-line cleaning units 201 (such as unblocking clogs or replacing easily damaged parts). Components such as filters and inlet control valves 205 are independently assembled, allowing for targeted maintenance without requiring overall shutdown, significantly reducing downtime and operating costs. Multiple single-line cleaning units 201 are arranged side-by-side, synergizing with the multi-line parallel design of the primary multi-line co-washing mechanism 100, enabling simultaneous secondary precision cleaning of multiple high-voltage cables 600 without affecting batch production efficiency. Furthermore, the number of single-line cleaning units 201 can be flexibly increased or decreased according to production capacity requirements, significantly improving the scalability of the production line compared to traditional single-cable cleaning equipment.

[0041] The high-voltage cable 600 passes vertically from bottom to top through the vertical cleaning pipe 2012. The waste liquid after cleaning can naturally flow back to the primary multi-line co-washing mechanism 100 under gravity, avoiding the problem of waste liquid adhering to the surface of the high-voltage cable 600 for a long time during horizontal cleaning. This reduces the risk of liquid residue in subsequent drying processes and lays a crucial foundation for thoroughly eliminating water stains and improving enameling quality. The adapter beam 202 is directly installed on the primary multi-line co-washing mechanism 100. The lower end of the single-line cleaning unit 201 extends into the secondary cleaning chamber 105, ensuring a tight connection between the secondary single-line cleaning mechanism and the primary co-washing mechanism. After the high-voltage cable 600 enters the secondary cleaning chamber 105 from the primary cleaning chamber 104 via the conductor sleeve 103, it can directly enter the single-line cleaning unit 201 for precise cleaning without additional transfer or positioning. This avoids the risk of new contaminants adhering to the surface of the high-voltage cable 600 during intermediate steps, ensuring the continuity and cleanliness of the cleaning process.

[0042] In summary, the secondary multi-line independent cleaning mechanism 200 in this embodiment, through one-to-one precise cleaning, closed-loop filtration circulation, and modular adjustable design, not only solves the problems of incomplete decontamination, poor adaptability, and cross-contamination among multiple lines in traditional primary cleaning, but also balances environmental protection, economy, and ease of maintenance through the recycling of cleaning fluid and the detachable structural design. Its core value lies in providing a deep, uniform, and clean secondary cleaning guarantee for the high-voltage cable 600 before enameling, thoroughly removing residual contaminants and potential liquid stains, providing a high-cleanliness conductor surface for subsequent drying and enameling processes, and ultimately helping to improve the adhesion, uniformity, and insulation reliability of the enameling layer, adapting to the industrial processing needs of large-scale, multi-specification high-voltage cables 600.

[0043] As a preferred embodiment of the present invention, such as Figures 6-8As shown, a liquid distribution cylinder 2011 is coaxially arranged above the vertical cleaning pipe 2012. The lower diameter of the liquid distribution cylinder 2011 gradually decreases downward in the vertical direction, and the small diameter end of the liquid distribution cylinder 2011 is connected to the upper end of the vertical cleaning pipe 2012. The liquid inlet branch pipe 204 is eccentrically connected to the peripheral wall of the liquid distribution cylinder 2011.

[0044] In this embodiment, the inlet branch pipe 204 is eccentrically connected to the peripheral wall of the distribution cylinder 2011. Cleaning fluid with a certain pressure is injected into the distribution cylinder 2011 from the eccentric direction, forming a rotating flow due to the guidance of the cylinder wall and the fluid's inertia. Combined with the structure of the distribution cylinder 2011 that tapers downwards vertically, the velocity of the rotating fluid gradually increases during its downward convergence, ultimately entering the vertical cleaning pipe 2012 in the form of a strong spiral flow. Compared to traditional linear flushing, the spiral flow can create a surrounding shearing flush on the surface of the high-voltage cable 600 passing through the vertical cleaning pipe 2012. This not only removes surface contaminants but also penetrates into blind areas such as the twisted seams and grooves of the high-voltage cable 600 through the rotating impact force, thoroughly removing residual micro-oxidation particles and stubborn oil stains. This solves the core defects of traditional cleaning methods, such as single-point flushing and blind area residue. The tapered design at the bottom of the liquid dispensing cylinder 2011 creates a natural velocity gradient in the cleaning liquid during its flow (the upper velocity is gentle, and the lower velocity is concentrated). This avoids damage to the surface of the high-voltage cable 600 caused by excessively high local velocity, and also creates high-pressure focused scouring within the vertical cleaning pipe 2012. This precisely removes complex contaminants with strong adhesion to the surface of the high-voltage cable 600, enhancing the deep cleaning capability of the secondary independent wash and laying the foundation for subsequent stain-free drying.

[0045] As a preferred embodiment of the present invention, such as Figures 6-8As shown, a connector 2013 is coaxially constructed at the upper end of the liquid dispensing cylinder 2011. The lower end of the vertical movable tube 2014 is movably inserted into the connector 2013. A liquid stain removal core 2015 is provided between the vertical cleaning tube 2012 and the vertical movable tube 2014. A wire passage 2016 is constructed at the center of the liquid stain removal core 2015, through which the high-voltage cable 600 passes. Multiple guide ports 2017 are opened on the upper peripheral wall of the vertical movable tube 2014, located at the upper end of the liquid stain removal core 2015. A liquid guiding sleeve 2018 is fitted over the vertical movable tube 2014, and all the guide ports 2017 are located within the liquid guiding sleeve 2018. A discharge pipe 2019 is connected to the liquid guide sleeve 2018, and the discharge pipe 2019 is connected to the primary multi-line co-washing mechanism 100. The upper end of each vertical movable tube 2014 is detachably connected to a movable seat 207, which is connected to a vertical drive component 208. By controlling the movement of the vertical drive component 208, the movable seat 207 drives the vertical movable tube 2014 to move downward, thereby squeezing the liquid stain removal core 2015, causing the water adsorbed in the liquid stain removal core 2015 to be squeezed out. Part of the squeezed water is discharged through the vertical cleaning tube 2012, and the other part of the squeezed water enters the liquid guide sleeve 2018, and then is discharged to the secondary cleaning chamber 105 through the discharge pipe 2019.

[0046] When the high-voltage cable 600 passes through the cable passage 2016 of the liquid stain removal core 2015, the cable passage 2016 is in close contact with the surface of the high-voltage cable 600. This allows for the physical scraping to peel away the free water and cleaning fluid film from the surface of the high-voltage cable 600. Then, in conjunction with the vertical drive component 208 driving the movable seat 207 to move the vertical movable tube 2014 downwards, precisely squeezing the liquid stain removal core 2015 and thoroughly squeezing out the capillary water and crevice water absorbed by the core. Compared to the inefficient stain removal methods of traditional brushes and air knives that rely on passive blowing, this design achieves dual active stain removal through scraping and squeezing, fundamentally reducing residual moisture on the surface of the high-voltage cable 600 and preventing water stains from forming after drying. Traditional liquid stain removal components (such as sponges and brushes) easily become saturated after absorbing moisture, requiring frequent replacement or manual cleaning, which affects production efficiency. This structure, through the periodic action of the vertical drive component 208, can periodically squeeze and dehydrate the liquid stain removal core 2015, squeezing out and recovering the adsorbed water, so that the liquid stain removal core 2015 always remains in a dry and efficient stain removal state, eliminating the need for frequent disassembly and replacement, extending the core's service life, and ensuring the stability of continuous production.

[0047] In this embodiment, the water discharged by squeezing is recovered in two paths. One path flows back to the secondary cleaning chamber 105 via the vertical cleaning pipe 2012, and the other path enters the liquid guide sleeve 2018 through the guide port 2017, and then is discharged to the secondary cleaning chamber 105 via the discharge pipe 2019. This design achieves a fully closed-loop recovery of the cleaning fluid, avoiding waste caused by water loss or direct discharge during stain removal, reducing the cost of replenishing new fluid and the pressure on wastewater treatment, and meeting the requirements of environmentally friendly production. The recovered water is directly discharged to the secondary cleaning chamber 105, rather than flowing back to the primary cleaning chamber 104, ensuring that the recovered fluid does not mix with heavy pollutants, guaranteeing the cleanliness of the cleaning fluid in the secondary cleaning chamber 105, and preventing secondary contamination of the high-voltage cable 600 or affecting the subsequent cleaning effect, forming a clean cycle of cleaning, stain removal, recovery, and reuse.

[0048] In this embodiment, the stroke and pressure of the vertical drive component 208 can be flexibly adjusted. By adjusting the downward pressing distance of the movable seat 207, the squeezing force can be increased for large-diameter high-voltage cables 600 or high-voltage cables 600 with deep surface grooves to ensure thorough descaling; the pressure can also be reduced for high-voltage cables 600 made of softer materials (such as aluminum high-voltage cables 600) or with easily damaged surfaces to avoid scratching the surface of the high-voltage cables 600. At the same time, the cable passage 2016 can deform slightly with the core compression to adapt to high-voltage cables 600 of different diameters, improving the versatility of the mechanism. The insertion tube 2013 at the upper end of the liquid dispensing cylinder 2011 and the movable insertion at the lower end of the vertical movable tube 2014 provide precise guidance for the up and down movement of the vertical movable tube 2014, avoiding uneven squeezing caused by misalignment; it also seals the liquid flow channel to prevent splashing of water discharged during squeezing, ensuring that water is recovered along a preset path, and guaranteeing the cleanliness and stability of the descaling process.

[0049] As a preferred embodiment of the present invention, such as Figure 1 , Figure 9 As shown, the drying mechanism 300 includes a drying cylinder 301, the inlet end of which is higher than its outlet end. A high-voltage cable 600 extends from the inlet end of the drying cylinder 301 along the inclined direction of the drying cylinder 301 to the outlet end of the drying cylinder 301. An exhaust connector 302 is connected to the upper end of the inlet end of the drying cylinder 301. A fixing seat 303 is constructed on the drying cylinder 301 for fixing the drying cylinder 301 to a support frame.

[0050] During the drying process, the hot steam formed by the evaporation of moisture is less dense than air and naturally rises. The vent connector 302, connected to the upper end of the inlet of the drying cylinder 301, perfectly matches the rising trend of the steam, allowing for rapid venting of steam to the outside of the drying cylinder 301. This avoids the problem of steam stagnation and condensation inside the cylinder caused by improperly positioned vents in traditional drying processes. Timely steam discharge maintains a dry environment inside the drying cylinder 301 and prevents secondary dampness caused by condensation adhering to the surface of the high-voltage cable 600, ensuring the drying effect from an environmental perspective. The high-position design of the vent connector 302 prevents excessive heat loss during steam discharge, helping to maintain a stable temperature field inside the drying cylinder 301 and avoiding localized temperature fluctuations caused by frequent venting. This stable temperature environment ensures consistent drying results for multiple high-voltage cables 600 running side-by-side, preventing batch-to-batch differences where some cables are fully dried while others retain moisture, thus improving the quality stability of mass production.

[0051] As a preferred embodiment of the present invention, such as Figure 10-13 As shown, the multi-stage enameling mechanism 400 includes multiple enameling units arranged vertically at intervals. These enameling units are respectively mounted on two vertical mounting rails 413 on both sides. The paint inlet branch pipe 406 of each enameling unit is connected to the paint inlet main pipe 410, and the paint outlet branch pipe 405 of each enameling unit is connected to the paint outlet main pipe 407. A paint inlet control valve 412 is installed on the paint inlet connector 411 of the paint inlet main pipe 410, and a paint outlet control valve 409 is installed on the paint outlet connector 408 of the paint outlet main pipe 407. The paint outlet connector 408 is connected to the inlet end of the intermediate tank, the outlet end of the intermediate tank is connected to the inlet end of the circulating pump, and the outlet end of the circulating pump is connected to the paint inlet connector 411.

[0052] In this embodiment, the enameling unit includes a transverse assembly 401 mounted on two vertical mounting rails 413 at both ends. Multiple tapered paint grooves 403 are spaced apart along the length of the upper end face of the transverse assembly 401. The lower end of each tapered paint groove 403 is connected to a paint discharge sleeve 402 through a wire hole 404. The paint discharge sleeve 402 is constructed on the lower end face of the transverse assembly 401. A paint inlet branch pipe 406 is connected to the tapered paint groove 403, and a paint discharge branch pipe 405 is connected to the paint discharge sleeve 402.

[0053] In this embodiment, multiple enameled units are arranged vertically at intervals. The high-voltage cable 600 passes through each enameled unit in sequence for multiple thin coatings. Compared with the traditional single-coat thick coating process, this avoids problems such as insufficient curing and internal stress concentration caused by excessive coating thickness. The coating layer can cure quickly after each thin coating, and the subsequent coating adheres tightly to the previous layer, which not only improves the overall adhesion of the coating layer, but also eliminates defects such as pinholes and cracks that are prone to occur in thick coating, ensuring the insulation reliability of the high-voltage cable 600. The conical enameled grooves 403 on the transverse assembly 401 are arranged at intervals along the length direction and correspond one-to-one with the high-voltage cable 600. After the paint liquid is injected into the conical enameled groove 403 through the paint inlet branch pipe 406, it is guided by the conical structure and smoothly converges along the groove wall to the lower conductor hole 404, and finally evenly coats the surface of the high-voltage cable 600 passing through the conductor hole 404. The conical structure prevents paint splashing or localized accumulation, ensuring a consistent paint thickness around the circumference of the high-voltage cable 600. This solves the uniformity problem of traditional enameling where one side is thicker than the other, improving the consistency of product appearance and insulation performance. The paint continuously flows within the channel formed by the conical paint tank 403, conductor hole 404, paint drain sleeve 402, and paint drain branch pipe 405, preventing sedimentation and uneven viscosity caused by prolonged standing. This ensures that the paint in contact with the high-voltage cable 600 maintains a stable performance state. Stable paint characteristics result in a smoother coating surface, reducing defects such as pinholes and bubbles, further improving the insulation reliability and appearance quality of the enameled layer.

[0054] In this embodiment, the paint discharge sleeves 402 of each enameling unit collect the incompletely adhered paint liquid through the paint discharge branch pipes 405 to the paint discharge main pipe 407, which then guides it into the intermediate tank via the paint discharge connector 408. Finally, it is pumped back to the paint inlet main pipe 410 by a circulation pump, achieving a closed-loop recycling and reuse of the paint liquid. The paint discharge sleeves 402, as key connecting components for paint liquid return, ensure efficient recovery of unused paint liquid, avoiding the problems of direct discharge or stagnation and waste of paint liquid in traditional enameling processes. This significantly reduces paint consumption costs and environmental protection pressure, meeting the production requirements for energy conservation and emission reduction. Furthermore, the intermediate tank is always maintained under negative pressure to facilitate the smooth and efficient entry of the paint liquid from the paint discharge sleeves 402 into the intermediate tank. The intermediate tank buffers the recovered paint liquid, and in conjunction with the pumping action, ensures thorough mixing of the paint liquid throughout the circulation system, preventing localized imbalances in paint concentration and viscosity. Compared to traditional open-loop painting, closed-loop circulation reduces the contact area between the paint and air, reduces the loss of paint oxidation and evaporation, ensures that the paint injected into each enameling unit has consistent performance, and guarantees the stability of coating quality from the source.

[0055] In this embodiment, multiple enameled units are mounted on both sides of a vertical mounting rail 413. The spacing or number of enameled units can be adjusted up and down along the vertical mounting rail 413 according to the insulation thickness requirements of the high-voltage cable 600. For example, when a thicker insulation layer is required, the number of enameled units can be increased and the spacing reduced; when a thinner insulation layer is required, the number of units can be reduced or the spacing increased. Simultaneously, the paint inlet control valve 412 of the paint inlet manifold 410 and the paint outlet control valve 409 of the paint outlet manifold 407 can work together to regulate the total paint flow rate, adapting to the painting needs of high-voltage cables 600 with different diameters. Compared to traditional fixed-structure enameling equipment, this significantly improves adaptability to different product specifications and reduces equipment modification costs.

[0056] In this embodiment, the injection, coating, and return of the paint are all completed within a closed pipeline and tank. The tight connection between the paint drain sleeve 402 and the paint drain branch pipe 405 prevents paint leakage or splashing, reduces the risk of dust and other impurities mixing into the paint, ensures the cleanliness of the coating process, and avoids the decline in paint adhesion or the deterioration of insulation performance caused by impurities. At the same time, the closed structure reduces the pollution of the operating environment by paint evaporation and improves production safety. The enameling unit, the vertical mounting rail 413, and the horizontal assembly 401 are all detachably connected. The structure of components such as the paint drain sleeve 402 and the conical enameling tank 403 is clear. In daily operations, individual units can be disassembled for cleaning and pipeline unblocking without the need for a complete shutdown. At the same time, the number of enameling units can be flexibly increased or decreased according to production capacity requirements, improving the expansion flexibility of the production line and adapting to the needs of different production scales.

[0057] In summary, the multi-stage enameling mechanism 400, through its integrated design of graded thin coating, closed-loop paint circulation, and modular adjustment, integrates the coating uniformity, paint stability, cost-effectiveness, and adaptability of the enameling process. The interconnected design of the paint discharge sleeve 402 and the paint discharge branch pipe 405 establishes a continuous cycle of paint supply, coating, and return, avoiding paint waste and performance degradation while ensuring consistent coating quality. Combined with the multi-stage thin coating and vertical adjustment structure, it further solves the core problems of traditional enameling, ultimately achieving high-quality results for the high-voltage cable 600, including strong adhesion, uniform thickness, reliable insulation, and a smooth appearance. Simultaneously, it meets the needs of multi-specification processing, mass production, and cost control, providing crucial assurance for the long-term safe operation of the high-voltage cable 600.
