Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, in particular to a cable for a high-power energy storage power station with easy heat dissipation and a processing technology thereof. Background Art

[0002] Energy storage power stations, as important 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. The operation of high-power energy storage power stations requires a large number of cables for power transmission. These cables typically have large cross-sectional areas to meet the high power transmission requirements. However, when high currents flow through the cables, significant heat buildup occurs, causing the internal conductor temperature to rise. This not only affects the transmission efficiency of the cables but also significantly shortens their service life.

[0003] Traditional cables used in high-power energy storage power stations face significant heat dissipation bottlenecks. While increasing the heat dissipation area by creating heat dissipation slots on the cable surface can be achieved, this design faces numerous technical challenges in actual production.

[0004] First, the grooves created during cable extrusion weaken the cable's overall mechanical strength. The newly extruded cable material hasn't fully solidified yet and is susceptible to deformation under its own weight and external stress, severely impacting the geometric accuracy and electrical performance of the finished cable. More critically, because the grooves are created during extrusion, the cable surface isn't fully hardened. As the cable continues to be extruded, the material at the edges of the grooves tends to flow and deform, resulting in irregular shapes and inconsistent dimensions. This not only affects heat dissipation but can also cause localized stress concentrations. Summary of the Invention

[0005] In order to solve the problems mentioned in the above background technology, the purpose of the present invention is to provide a cable for high-power energy storage power stations that is easy to dissipate heat and a processing technology thereof. After the cable with grooves on the surface is extruded, the processing technology quickly hardens the cable through step-by-step cooling to prevent deformation, and uses a synchronous groove scraping structure to perform secondary trimming on the cable surface grooves to ensure that the heat dissipation grooves on the cable surface are evenly distributed and smooth.

[0006] To achieve the above objectives, the present application provides a processing technology for cables for high-power energy storage power stations that are easy to dissipate heat. The processing technology is used to process the cables, and the technical solution is as follows:

[0007] It includes a cable extrusion body and a slotting module arranged at the extrusion end of the cable extrusion body. A basic frame is provided on one side of the output end of the cable extrusion body. A lead-out channel for the lead-out cable is provided on one side of the slotting module. It also includes a cooling component, a synchronous slotting mechanism and a shaping guide frame. The following process steps are performed:

[0008] Step 1: The cable extrusion body and the slotting module extrude the cable with the slotted surface. The cable is led out through the lead-out channel. As the cable moves forward, it enters the cooling space formed by the cooling component. The cooling component forms a progressive cooling effect as the cable moves forward, 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 a synchronous grooving mechanism, which further scrapes the grooves on the cable surface to help shape the groove body. The cable with the surface grooves further processed then enters the shaping guide frame.

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

[0011] The cooling assembly forms a cooling channel with decreasing temperature along the cable movement path, thereby preventing the cable surface from cracking due to excessive cooling speed.

[0012] The synchronous grooving mechanism surrounds the cable moving path, and the multiple scraping ends of the synchronous grooving mechanism correspond to the multiple grooves on the cable surface respectively, and scrape the multiple grooves on the surface of the cable that has completed cooling respectively, making the grooves smoother.

[0013] Furthermore, the cooling component is arranged along the outside of the derivation channel and distributed on the cable moving path. The cooling component includes a cold air generating body and a surrounding injection pipe. The cold air generating body is arranged on the basic frame. The surrounding injection pipes are arranged in a group along the derivation channel. The cold air injection end of the surrounding injection pipe is facing the inside of the derivation channel, and the cold air temperature of the multiple surrounding injection pipes decreases along the cable moving path.

[0014] Furthermore, the surrounding injection pipe includes a surrounding pipe and a nozzle, one end of the surrounding pipe is connected to the cold air generating body, and the other end surrounds the outlet channel, and the nozzles are arranged in a group on the surrounding pipe, and the multiple nozzles all penetrate the outlet channel and inject cold air into the outlet channel;

[0015] Among them, the nozzle parts of the plurality of surrounding injection pipes are staggeredly distributed on the outlet channel, so that staggered cold air decreasing areas are formed in the outlet channel, which helps to inject the cold air evenly.

[0016] By setting up multiple cooling components on the cable movement path, a gradient cooling environment is constructed in which the temperature decreases and then rises again, so that a hardened layer is formed on the surface of the cable and then gradually solidified deep down.

[0017] As a further improvement of the present technical solution, the synchronous grooving mechanism includes a mounting platform, an extrusion and scraping assembly, and a driving member. The mounting platform is movably sleeved on the end of the shaping guide frame, the extrusion and scraping assembly is arranged at the end of the mounting platform, and the driving member acts on the extrusion and scraping assembly.

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

[0019] The driving member includes a control push rod provided on the mounting platform and an extrusion ring movably sleeved on the outside of the mounting platform. One end of the extrusion 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 extrusion ring to move the extrusion ring push frame downward. A reset member is provided at the connection between the ring push frame and the positioning ring for resetting after moving downward.

[0020] There are a plurality of ring pushers and scraping blades arranged around the positioning ring, and the scraping blades are positioned facing the notches on the cable surface.

[0021] Furthermore, the shaping guide frame includes a support frame and a shaping tube, the support frame is arranged on the base frame, the shaping tube is arranged at the top of the support frame, and the end of the shaping tube is facing the channel opening of the outlet channel, and the synchronous grooving mechanism is arranged at the end of the shaping tube, and the synchronous grooving mechanism is located between the outlet channel and the shaping tube;

[0022] Among them, the inner wall of the shaping tube is provided with an annular protrusion which is engaged with 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, which has the advantages of improving the cable heat dissipation efficiency, processing stability and finished product quality.

[0024] The present invention also provides a cable made using the above-mentioned processing technology for a cable for a high-power energy storage power station with easy heat dissipation, comprising a conductive core, a protective rubber layer provided on the outside of the conductive core, and uniform heat dissipation grooves formed on the outside of the protective rubber layer;

[0025] Among them, the conductive core includes a conductor, an insulating medium, a shielding layer and a thermal conductive layer. There are three groups of conductors, which are arranged in a circular shape at the center of the conductive core. The three groups of conductors are wrapped with a shielding layer. An insulating medium is arranged between the shielding layer and the conductor. The outside of the shielding layer is covered with a thermal conductive layer, and the protective rubber layer is covered on the outside of the thermal conductive layer.

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

[0027] By arranging multiple surrounding injection pipes along the cable movement path, a gradient cooling environment is formed on the cable movement path after extrusion, thereby constructing a gradient cooling environment with decreasing and then rising temperature. The extruded slotted cable is gradually reduced from the extrusion temperature to the cooling temperature, and then gradually raised to room temperature, avoiding surface cracks caused by rapid shrinkage.

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

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] In order to solve the problem that when heat dissipation grooves are opened on the surface of the cable to increase the heat dissipation area, the cable material is in a softened state during the extrusion molding stage, the structural strength is reduced after the surface grooves are opened, and the unhardened material after extrusion is easy to flow, resulting in deformation of the groove edges, the present invention proposes a processing technology for cables for high-power energy storage power stations with easy heat dissipation.

[0039] Reference Figures 1 to 7 As shown, the cable processing technology is used in the process of extruding slotted cables. The processing device includes a cable extrusion body 1 and a slotting module 2 provided at the extrusion end of the cable extrusion body 1. A basic frame 3 is provided on the output end of the cable extrusion body 1, and a lead-out channel 4 for leading out the cable is provided on one side of the slotting module 2. The device also includes a cooling component 5, a synchronous slotting mechanism 6 and a shaping guide frame 7. The following process steps are performed:

[0040] Step 1: The cable extrusion body 1 and the slotting module 2 extrude the cable with the slotted surface. The cable is discharged through the outlet channel 4. As the cable moves forward, it enters the cooling space formed by the cooling component 5. The cooling component 5 forms a progressive cooling effect as the cable moves forward, 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, which further scrapes the grooves on the cable surface to help the groove body to 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 frame 7 and continues to move forward. The plastic part of the shaping guide frame 7 is used to shape the cable. During the export process, the cable is prevented from bending and the weight of the cable is prevented from affecting the subsequent cable extrusion.

[0043] The cooling component 5 forms a cooling channel with decreasing temperature along the cable moving path to prevent the cable surface from cracking due to excessive cooling speed.

[0044] The synchronous grooving mechanism 6 surrounds the cable moving path, and the multiple scraping ends of the synchronous grooving mechanism 6 correspond to the multiple grooves on the cable surface respectively, scraping the multiple grooves on the surface of the cable that has completed cooling respectively, making 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 travel path. The cooling assembly 5 includes a cold air generating body 51 and a surrounding injection pipe 52. The cold air generating body 51 is arranged on the base frame 3. A plurality of surrounding injection pipes 52 are arranged in a group along the outlet channel 4. The cold air injection ends of the surrounding injection pipes 52 face the inside of the outlet channel 4, and the cold air temperature of the plurality of surrounding injection pipes 52 decreases along the cable travel path.

[0047] The cooling air generating body 51 is a cooling gas generating device, which is realized by a compressor and a refrigerant circulation system, and is fixedly mounted on the base frame 3 to ensure the stability of cooling air supply.

[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 surrounds the outlet channel 4. A plurality of nozzles 522 are arranged in a group on the surrounding pipe 521, and the plurality of nozzles 522 all penetrate the outlet channel 4 and inject cold air into the outlet channel 4.

[0049] Among them, multiple nozzles 522 surrounding the injection pipe 52 are partially staggered on the outlet channel 4, and a partition is set on the inside of the outlet channel 4 to prevent the cold air in the same area from escaping to other areas in the outlet channel 4, thereby forming a cold air decreasing area in the outlet channel 4, which helps to inject the cold air evenly.

[0050] It should be clarified that the cooling component 5 is arranged along the moving path of the extruded cable. Specifically, multiple cold air injection units, namely, surrounding injection pipes 52, are arranged along the moving path of the cable. A gradient cooling environment is formed by setting cold air injection units of different temperature sections. Among them, the first surrounding injection pipe 52 adjacent to the extrusion end of the cable sprays cold air with a higher temperature, and the injection temperature of each subsequent surrounding injection pipe 52 gradually decreases along the moving direction. The injection temperature of the last section of the surrounding injection pipe 52 is increased again, so that the grooved area on the cable surface continues to receive 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 up an independent temperature control module. When facing different materials, it can control the degree of temperature step change on the cooling path to adapt to more materials.

[0051] In this embodiment, the temperature-decreasing cooling area formed by the cooling component 5 refers to a cooling device arranged along the moving direction of the cable through multiple temperature zones, using multiple groups of independently temperature-controlled cold air injection units, and the temperature gradient between adjacent units is controlled within a certain range. Specifically, the cable enters the outlet channel 4 after extrusion and slotting. The cold air injection unit in the front half of the cooling component 5 performs a preliminary cooling of the cable surface to form a hardened thin layer of the surface material. The cold air injection unit in the middle section lowers the temperature and continues to cool to promote the solidification of the middle layer material on the cable surface. The cold air injection unit in the second half increases the temperature and slowly increases the temperature of the cable surface material, so that the extruded slotted cable is gradually reduced from the extrusion temperature to the cooling temperature, and then gradually increased to room temperature, to avoid surface cracks caused by rapid shrinkage, and prevent the material from sudden cooling and cracking through progressive 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 body of the grooved cable surface so that the groove body has a regular shape and consistent size, a synchronous grooving mechanism 6 is provided here, including a mounting platform 61, an extrusion and scraping assembly 62 and a driving member 63. The mounting platform 61 is movably sleeved on the end of the shaping guide frame 7, the extrusion and scraping assembly 62 is provided at the end of the mounting platform 61, and the driving member 63 acts on the extrusion and scraping assembly 62.

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

[0055] The driving member 63 includes a control push rod 631 arranged on the mounting platform 61 and an extrusion ring 632 movably sleeved on the outside of the mounting platform 61. One end of the extrusion ring 632 is connected to the control push rod 631, and the other end acts on the other end of the ring push frame 623. The control push rod 631 pushes the extrusion ring 632 to move and move the extrusion ring push frame 623 downward. A reset member is provided at the connection between the ring push frame 623 and the positioning ring 621 for resetting after moving downward.

[0056] A plurality of ring pushers 623 and scraping blades 622 are arranged around the positioning ring 621, and the scraping blades 622 are positioned facing the notches on the cable surface.

[0057] When the extrusion ring 632 moves forward, it can squeeze multiple ring pushers 623 at the same time, causing multiple synchronous surfaces to move axially toward the cable surface grooves, allowing the scraping blades 622 at the bottom ends of the multiple ring pushers 623 to scrape the cable surface grooves.

[0058] The scraping blade 622 at the scraping end of the synchronous grooving mechanism 6 is positioned in a mechanical alignment manner to ensure that the scraping tool and the groove position are accurately matched, wherein the concave groove on the cable surface is used as a reference, the end of the scraping blade 622 is an inclined concave arc edge, and the corresponding groove is self-aligned. Specifically, the hardened cable enters the synchronous grooving position, that is, the inner side of the positioning ring 621, and the surrounding scraping blades 622 move a certain depth along the axial direction of the groove to complete the cutting, thereby removing the burrs generated during extrusion and the material accumulation generated by the 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 arranged on the base frame 3. The shaping tube 72 is arranged on the top of the support frame 71, and the end of the shaping tube 72 is facing the channel opening of the outlet channel 4. The synchronous groove cutting mechanism 6 is arranged at the end of the shaping tube 72, and the synchronous groove cutting mechanism 6 is located between the outlet channel 4 and the shaping tube 72.

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

[0061] The scraped cable enters the shaping tube 72, and the annular protrusion on the inner wall of the shaping tube 72 is engaged with the cable groove to prevent radial deformation.

[0062] It should be made clear that traditional cable grooving processing mostly uses a fixed scraper for single-point trimming, which is prone to inconsistent scraping depth due to fluctuations in cable transportation and cannot simultaneously process multi-groove structures. Here, the circumferential pressure distribution of the extrusion ring 632 is used to achieve multi-point synchronous force application, and multiple scraping blades 622 are used to simultaneously remove burrs generated during grooving and 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 controlling the push rod 631, and the multiple ring push frames 623 are moved down and drive the multiple scraping blades 622 close to the cable groove, so that the scraping blades 622 are aligned with the grooves on the cable surface, and then the control push rod 631 is used to continue to provide thrust, so that the conical inner wall of the extrusion ring 632 contacts the end inclined surface of the ring push frame 623. The multiple scraping blades 622 will be subjected to axial thrust, driving the scraping blades 622 to contact the bottom of the cable groove with a constant pressure, ensuring that the depth of the grooves on the surfaces of multiple cables 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, which is made by the above-mentioned processing technology. In order to increase the contact area with the air and quickly dissipate heat, it is provided with a conductive core 8, a protective rubber layer 9 is provided on the outside of the conductive core 8, and uniform heat dissipation grooves 10 are opened on the outside of the protective rubber layer 9;

[0065] Among them, the conductive core 8 includes a conductor 81, an insulating medium 82, a shielding layer 83 and a thermal conductive layer 84. There are three groups of conductors 81, which are arranged in a circular shape at the center of the conductive core 8. The three groups of conductors 81 are wrapped with a shielding layer 83. An insulating medium 82 is arranged between the shielding layer 83 and the conductor 81. The outside of the shielding layer 83 is covered with a thermal conductive layer 84, and the protective rubber layer 9 is covered on the outside of the thermal conductive layer 84.

[0066] It should be clarified that the conductive core 8 refers to the core structure that carries current inside the cable. The current distribution is optimized by the surrounding arrangement of three groups of conductors 81. The protective rubber layer 9 refers to the outermost protective structure of the cable, which is a rubber material. The heat dissipation grooves 10 on its surface are formed during extrusion and formed by secondary processing by 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 elaborated here.

[0067] Specifically, the conductive core 8 is arranged in three groups in a surrounding manner, so that the current is evenly distributed in space and the local temperature rise is reduced, while the heat dissipation grooves 10 on the outer surface of the protective rubber layer 9 increase the contact area with the air to improve the convective heat dissipation efficiency.

[0068] The above shows and describes 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 above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
