Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and in particular to cables for high-power energy storage power stations with easy heat dissipation and their processing technology. Background Technology

[0002] Energy storage power stations, as crucial equipment systems that store, convert, and release electrical energy through electrochemical cells or electromagnetic energy storage media, play a key role in modern power systems. During the operation of high-power energy storage power stations, a large number of cables are required for power transmission. These cables typically have large cross-sectional areas to meet the demands of high power transmission. However, the passage of large currents through these cables generates significant heat accumulation, causing the internal conductor temperature to rise. This not only affects the cable's transmission efficiency but also significantly shortens its lifespan.

[0003] Traditional cables used in high-power energy storage power stations suffer from significant heat dissipation bottlenecks. Although heat dissipation grooves can be added to the cable surface to increase the heat dissipation area, this design faces numerous technical challenges in actual production.

[0004] First, the grooved structure created during cable extrusion weakens the overall mechanical strength of the cable. Furthermore, the freshly extruded cable material is not fully cured and is prone to deformation under its own weight and external stress, severely affecting the geometric accuracy and electrical performance of the finished cable. More importantly, because the grooves are created during extrusion, the cable surface is not fully hardened. As the cable continues to be extruded, the material at the edges of the grooves is prone to flow deformation, resulting in irregular groove shapes and inconsistent dimensions. This not only affects heat dissipation but may also cause localized stress concentrations. Summary of the Invention

[0005] To address the problems mentioned in the background section, the present invention aims to provide a high-power energy storage power station cable with easy heat dissipation and its processing technology. After the cable with grooved surface is extruded, the cable is rapidly hardened by stepped cooling to prevent deformation. A synchronous groove scraping structure is used to perform secondary finishing on the grooves on the cable surface to ensure that the heat dissipation grooves on the cable surface are evenly distributed and smooth.

[0006] To achieve the above objectives, this application provides a processing technology for cables used in high-power energy storage power stations with easy heat dissipation. The technical solution for processing cables is as follows:

[0007] The device includes a cable extrusion body and a grooving module disposed at the extrusion end of the cable extrusion body. A base frame is provided on one side of the output end of the cable extrusion body, and an output channel for the cable is provided on one side of the grooving module. It also includes a cooling assembly, a synchronous grooving mechanism, and a shaping guide frame, and performs the following process steps:

[0008] Step 1: The cable extrusion body and the grooving module extrude the grooved cable. The cable is then discharged through the discharge channel. As the cable moves forward, it enters the cooling space formed by the cooling components. The cooling components create a progressive cooling effect during the cable's forward movement, allowing the cable surface to be completely cooled.

[0009] Step 2: The cooled cable enters one end of the shaping guide frame. At the end of the shaping guide frame, the cable first passes through the synchronous grooving mechanism, which further scrapes the grooves on the surface of the cable to help the grooves be formed. Then, the cable with the surface grooves further processed enters the shaping guide frame.

[0010] Step 3: The cable enters the shaping guide and continues to move forward. The plastic part of the shaping guide is used to shape the cable. During the extrusion process, the cable is prevented from bending and its weight is avoided from affecting the subsequent cable extrusion.

[0011] The cooling component forms a cooling channel with decreasing temperature along the cable's movement path to prevent excessively rapid cooling from causing cracks on the cable surface.

[0012] The synchronous grooving mechanism surrounds the cable movement path, and the multiple scraping ends of the synchronous grooving mechanism correspond to multiple slots on the cable surface, scraping the multiple slots on the cooled cable surface to make the grooves smoother.

[0013] Furthermore, the cooling assembly is arranged along the outside of the outlet channel and distributed along the cable movement path. The cooling assembly includes a cold air generating body and surrounding spray pipes. The cold air generating body is arranged on the base frame. Multiple surrounding spray pipes are arranged in a group along the outlet channel. The cold air spray end of the surrounding spray pipes faces the inside of the outlet channel, and the cold air temperature of the multiple surrounding spray pipes decreases along the cable movement path.

[0014] Furthermore, the surrounding injection pipe includes a surrounding pipe and nozzles. One end of the surrounding pipe is connected to the cold air generating body, and the other end is wrapped around the outlet channel. Multiple nozzles are arranged in a group on the surrounding pipe, and multiple nozzles pass through the outlet channel and inject cold air into the inside of the outlet channel.

[0015] The nozzle sections of the multiple surrounding injection pipes are staggered on the outlet channel, forming staggered cold air reduction zones within the outlet channel, which helps to ensure uniform cold air injection.

[0016] By setting multiple cooling components along the cable's movement path, a gradient cooling environment is created, with the temperature decreasing and then increasing again, allowing the cable surface to gradually harden and deepen after a hardened layer is formed.

[0017] As a further improvement to this technical solution, the synchronous grooving mechanism includes an installation platform, an extrusion scraping assembly, and a driving component. The installation platform is movably sleeved on the end of the shaping guide frame, the extrusion scraping assembly is disposed at the end of the installation platform, and the driving component acts on the extrusion scraping assembly.

[0018] The extrusion scraping assembly includes a positioning ring connected to the mounting platform, a scraper blade, and a ring pusher frame for controlling the downward movement of the scraper blade. One end of the ring pusher frame movably passes through the positioning ring, and the scraper blade is disposed at the end of the ring pusher frame.

[0019] The driving component includes a control push rod mounted on the mounting platform and a compression ring movably sleeved on the outside of the mounting platform. One end of the compression ring is connected to the control push rod, and the other end acts on the other end of the ring push frame. The control push rod pushes the compression ring to move and moves the compression ring push frame downward. A reset component is provided at the connection between the ring push frame and the positioning ring to reset after downward movement.

[0020] The ring pusher and scraper are arranged in multiple ways around the positioning ring, and the scraper is positioned directly opposite the groove on the cable surface.

[0021] Furthermore, the shaping guide frame includes a support frame and a shaping tube. The support frame is mounted on the base frame, and the shaping tube is mounted on the top of the support frame, with the end of the shaping tube facing the outlet of the outlet channel. The synchronous grooving mechanism is mounted on the end of the shaping tube and is located between the outlet channel and the shaping tube.

[0022] The inner wall of the shaped tube has an annular protrusion that fits into the groove on the surface of the cable.

[0023] The synchronous grooving mechanism scrapes the grooving body to improve the forming accuracy, and the shaping guide frame prevents the cable from bending and deforming. It has the advantages of improving the cable heat dissipation efficiency, processing stability and finished product quality.

[0024] The present invention also provides a cable manufactured using the above-mentioned heat-dissipating high-power energy storage power station cable processing technology, which includes a conductive core, a protective rubber layer disposed on the outside of the conductive core, and uniform heat dissipation grooves formed on the outside of the protective rubber layer.

[0025] The conductive core includes a conductor, an insulating medium, a shielding layer, and a thermally conductive layer. There are three groups of conductors arranged in a ring around the center of the conductive core. The three groups of conductors are wrapped with a shielding layer. An insulating medium is provided between the shielding layer and the conductors. A thermally conductive layer is wrapped around the outside of the shielding layer. A protective rubber layer is wrapped around the outside of the thermally conductive layer.

[0026] Compared with the prior art, the heat-dissipating, high-power energy storage power station cable and its processing technology provided by the present invention have the following beneficial effects:

[0027] By arranging multiple surrounding jet pipes along the cable's movement path, a gradient cooling environment is formed on the cable's movement path after extrusion. This creates a gradient cooling environment where the temperature decreases and then rises again, allowing the extruded grooved cable to gradually decrease from the extrusion temperature to the cooling temperature and then gradually rise to room temperature, thus avoiding surface cracks caused by rapid shrinkage.

[0028] By controlling the push rod to move the extrusion ring forward and drive multiple scraper blades close to the cable groove, the scraper blades are aligned with the groove on the cable surface. The push rod continues to provide thrust, and the multiple scraper blades will be subjected to axial thrust, causing the scraper blades to contact the bottom of the cable groove with constant pressure. As the cable continues to move, synchronous scraping with consistent groove depth is formed on the cable surface, removing burrs generated during extrusion grooving and material accumulation caused by material flow.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] To address the issue that when creating heat dissipation grooves on the cable surface to increase the heat dissipation area, the cable material is in a softened state during the extrusion molding stage, resulting in reduced structural strength after surface grooving, and the unhardened material after extrusion is prone to flow, causing deformation at the groove edges, this invention proposes a processing technology for high-power energy storage power station cables with easy heat dissipation.

[0039] Reference Figures 1 to 7 As shown, this cable processing technology is used in the process of extruding grooved cables. The processing device includes a cable extrusion body 1 and a grooved module 2 set at the extrusion end of the cable extrusion body 1. A base frame 3 is set on one side of the output end of the cable extrusion body 1, and an output channel 4 for outputting the cable is set on one side of the grooved module 2. It also includes a cooling component 5, a synchronous grooving mechanism 6, and a shaping guide frame 7. The following process steps are performed:

[0040] Step 1: The cable extrusion body 1 and the grooving module 2 extrude the cable with grooved surfaces. The cable is discharged through the discharge channel 4. During the forward movement of the cable, it enters the cooling space formed by the cooling component 5. The cooling component 5 forms a progressive cooling effect during the forward movement of the cable, allowing the cable surface to be completely cooled.

[0041] Step 2: The cooled cable enters one end of the shaping guide frame 7. At the end of the shaping guide frame 7, the cable first passes through the synchronous grooving mechanism 6. The synchronous grooving mechanism 6 further scrapes the grooves on the surface of the cable to help the grooves be formed. Then the cable with the surface grooves further processed enters the shaping guide frame 7.

[0042] Step 3: The cable enters the shaping guide 7 and continues to move forward. The plastic part of the shaping guide 7 is used to shape the cable. During the discharge process, the cable is prevented from bending and its weight is avoided from affecting the subsequent cable extrusion.

[0043] Among them, the cooling component 5 forms a cooling channel with decreasing temperature along the cable movement path to prevent the cable surface from cracking due to excessively fast cooling speed.

[0044] The synchronous grooving mechanism 6 surrounds the cable movement path, and the multiple scraping ends of the synchronous grooving mechanism 6 correspond to the multiple slots on the cable surface, scraping the multiple slots on the cooled cable surface to make the grooves smoother.

[0045] Example 1

[0046] Reference Figures 1 to 7 As shown, the cooling assembly 5 is arranged along the outside of the outlet channel 4 and distributed along the cable movement path. The cooling assembly 5 includes a cold air generating body 51 and a surrounding spray pipe 52. The cold air generating body 51 is arranged on the base frame 3. Multiple surrounding spray pipes 52 are arranged in a group along the outlet channel 4. The cold air spray end of the surrounding spray pipe 52 faces the inside of the outlet channel 4, and the cold air temperature of the multiple surrounding spray pipes 52 decreases along the cable movement path.

[0047] The main body for generating cold air 51 is a refrigeration gas generating device, which is realized through a compressor and a refrigerant circulation system. The stability of the cold air supply is ensured by fixing it on the base frame 3.

[0048] like Figure 5 As shown, the surrounding injection pipe 52 includes a surrounding pipe 521 and a nozzle 522. One end of the surrounding pipe 521 is connected to the cold air generating body 51, and the other end is wrapped around the outlet channel 4. Multiple nozzles 522 are arranged in a group on the surrounding pipe 521, and multiple nozzles 522 pass through the outlet channel 4 and inject cold air into the inside of the outlet channel 4.

[0049] Among them, multiple nozzles 522 surrounding the injection pipe 52 are staggered on the outlet channel 4, and the outlet channel 4 is equipped with a partition to prevent the cold air in the same area from escaping to other areas in the outlet channel 4, thereby forming a cold air reduction area in the outlet channel 4 to help the cold air injection be uniform.

[0050] It should be clarified that the cooling component 5 is set along the moving path of the extruded cable. Specifically, multiple cold air injection units, i.e., surrounding injection pipes 52, are arranged along the moving path of the cable. By setting cold air injection units with different temperature ranges, a gradient cooling environment is formed. The first surrounding injection pipe 52 near the extrusion end of the cable sprays cold air at a higher temperature. The spraying temperature of each subsequent surrounding injection pipe 52 gradually decreases in the moving direction. The spraying temperature of the last section of surrounding injection pipe 52 increases again, so that the grooved area on the cable surface continuously receives cooling treatment that matches its hardening process during the movement, and finally approaches room temperature. Each surrounding injection pipe 52 can also achieve temperature control by setting an independent temperature control module. When dealing with different materials, it can control the degree of temperature gradient change on the cooling path and adapt to more materials.

[0051] In this embodiment, the temperature-decreasing cooling zone formed by the cooling component 5 refers to a cooling device arranged along the cable movement direction, using multiple temperature zones and multiple sets of independently temperature-controlled cold air jet units. The temperature gradient between adjacent units is controlled within a certain range. Specifically, after the cable is extruded and slotted, it enters the outlet channel 4. The first half of the cold air jet unit of the cooling component 5 initially cools the cable surface, causing the surface material to form a hardened thin layer. The middle section of the cold air jet unit further reduces the temperature, promoting the solidification of the middle layer material on the cable surface. The second half of the cold air jet unit increases the temperature, slowly raising the temperature of the cable surface material. This allows the extruded slotted cable to gradually decrease from the extrusion temperature to the cooling temperature, and then gradually rise to room temperature, avoiding surface cracks caused by rapid shrinkage. Progressive cooling prevents the material from cracking due to sudden cooling.

[0052] Example 2

[0053] like Figures 1 to 7 As shown, this embodiment is basically the same as the first embodiment. Preferably, in order to scrape the material that has flowed and deformed at the edge of the groove on the cable surface so that the groove shape is regular and the size is consistent, a synchronous grooving mechanism 6 is set here, which includes an installation platform 61, an extrusion scraping component 62 and a driving component 63. The installation platform 61 is movably sleeved on the end of the shaping guide frame 7, the extrusion scraping component 62 is set at the end of the installation platform 61, and the driving component 63 acts on the extrusion scraping component 62.

[0054] like Figure 6 As shown, the extrusion scraping assembly 62 includes a positioning ring 621 connected to the mounting platform 61, a scraper blade 622, and a ring pusher 623 that controls the downward movement of the scraper blade 622. One end of the ring pusher 623 movably passes through the positioning ring 621, and the scraper blade 622 is disposed at the end of the ring pusher 623. The ring pusher 623 is disposed on the positioning ring 621 through a guide sleeve, so that the movement of the ring pusher 623 is smooth.

[0055] The driving component 63 includes a control push rod 631 mounted on the mounting platform 61 and a compression ring 632 movably sleeved on the outside of the mounting platform 61. One end of the compression ring 632 is connected to the control push rod 631, and the other end acts on the other end of the ring pusher 623. The control push rod 631 pushes the compression ring 632 to move and move the compression ring pusher 623 downward. A reset component is provided at the connection between the ring pusher 623 and the positioning ring 621 to reset after downward movement.

[0056] Multiple ring pushers 623 and scrapers 622 are arranged around the positioning ring 621, and the scrapers 622 are positioned directly opposite the groove on the cable surface.

[0057] When the extrusion ring 632 moves forward, it can simultaneously extrude multiple ring pushers 623, causing multiple synchronous faces to move axially towards the cable surface groove, so that the scraper blades 622 at the bottom of the multiple ring pushers 623 are directly facing the cable surface groove to perform scraping operation.

[0058] The positioning method of the scraper blade 622 at the scraping end of the synchronous grooving mechanism 6 adopts mechanical alignment to ensure that the scraper tool and the groove position are accurately matched. The groove on the cable surface is used as a reference, and the end of the scraper blade 622 is an inclined concave arc edge, which is self-aligned with the corresponding groove. Specifically, after the hardened cable enters the synchronous grooving position, that is, the inner side of the positioning ring 621, the surrounding scraper blades 622 move a certain depth along the groove axis to complete the cutting, removing the burrs generated during extrusion and the material accumulation caused by material flow.

[0059] like Figure 3 As shown, the shaping guide frame 7 includes a support frame 71 and a shaping tube 72. The support frame 71 is set on the base frame 3, and the shaping tube 72 is set on the top of the support frame 71. The end of the shaping tube 72 is directly facing the channel opening of the outlet channel 4. The synchronous grooving mechanism 6 is set on the end of the shaping tube 72 and is located between the outlet channel 4 and the shaping tube 72.

[0060] The inner wall of the shaped tube 72 is provided with an annular protrusion that fits into the cable groove.

[0061] The scraped cable enters the shaping tube 72, where the annular protrusions on the inner wall of the shaping tube 72 fit into the cable groove to prevent radial deformation.

[0062] It should be clarified that traditional cable grooving processing often uses fixed scrapers for single-point trimming, which is prone to inconsistent scraping depth due to fluctuations in cable transport, and cannot process multi-groove structures simultaneously. Here, however, the pressure distribution of the extrusion ring 632 enables simultaneous force application at multiple points, and multiple scraper blades 622 are used to remove burrs generated during the extrusion of multiple cable surfaces and material accumulation caused by material flow.

[0063] In this embodiment, when the cable enters the shaping guide frame 7 after cooling, the extrusion ring 632 is pushed forward by the control push rod 631. Multiple ring push frames 623 are moved down and multiple scraper blades 622 are driven to approach the cable groove, so that the scraper blades 622 are aligned with the groove on the cable surface. Then, the control push rod 631 continues to provide thrust, so that the conical inner wall of the extrusion ring 632 contacts the inclined surface at the end of the ring push frame 623. The multiple scraper blades 622 will be subjected to axial thrust, which drives the scraper blades 622 to contact the bottom of the cable groove with constant pressure, ensuring that the groove depth of multiple cable surfaces is consistent.

[0064] like Figure 7As shown, the present invention also proposes a cable for a high-power energy storage power station with easy heat dissipation. It is manufactured by the above-mentioned processing technology. In order to increase the contact area with air and dissipate heat quickly, it is provided with a conductive core 8, a protective rubber layer 9 on the outside of the conductive core 8, and a uniform heat dissipation groove 10 on the outside of the protective rubber layer 9.

[0065] The conductive core 8 includes a conductor 81, an insulating medium 82, a shielding layer 83, and a thermally conductive layer 84. There are three sets of conductors 81, which are arranged in a ring around the center of the conductive core 8. The three sets of conductors 81 are wrapped with a shielding layer 83. An insulating medium 82 is provided between the shielding layer 83 and the conductors 81. The thermally conductive layer 84 is covered on the outside of the shielding layer 83, and a protective rubber layer 9 is covered on the outside of the thermally conductive layer 84.

[0066] It should be clarified that the conductive core 8 refers to the core structure inside the cable that carries the current. The current distribution is optimized by the surrounding arrangement of three sets of conductors 81. The protective rubber layer 9 refers to the outermost protective structure of the cable, which is made of rubber material. The heat dissipation grooves 10 on its surface are formed during extrusion and then formed by secondary scraping. The heat dissipation efficiency is improved by increasing the surface area. The structure between the conductive core 8 and the protective rubber layer 9 is a common structure and will not be described in detail here.

[0067] Specifically, the conductive core 8 adopts a three-group surrounding arrangement to distribute the current evenly in space and reduce local temperature rise, while the heat dissipation groove 10 on the outer surface of the protective rubber layer 9 increases the contact area with air and improves the convective heat dissipation efficiency.

[0068] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
