[0016] As a further improvement of the present technical solution, in S2, a plurality of sleeves are provided on the surface of the center line core, a sleeve belt is connected to the surface of the second sub-ring, one end of the sleeve belt is sleeved with the sleeve, and a connecting pin is provided on the surface of the first sub-ring, and the end of the connecting pin is snap-fitted with the sleeve.

[0017] As a further improvement of the present technical solution, the fixed body includes a horizontal plate and a vertical plate arranged at one end of the horizontal plate, a pair of clamping plates are plugged into the vertical plate, a screw shaft threadedly connected to the clamping plate is provided on the outer wall of the vertical plate, and a roller for clamping one end of the center line core is provided on the clamping plate;

[0018] The embedded body includes a skateboard and a pressure plate that is plugged into the upper and lower parts of the skateboard. The skateboard is slidably connected to the top of the cross plate. A bottom groove for placing the center line core is provided on the top of the skateboard. A first end plate with a rotatable connection is provided at both ends of the pressure plate. A rotating shaft with a rotatable connection is provided at both ends of the skateboard.

[0021] As a further improvement of the present technical solution, in S4, the winding directions of the inner layer of steel strip armor and the outer layer of steel strip armor are opposite.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the processing method of the long-life environmentally friendly energy storage cable, multiple conductors are fixedly connected to multiple elastic connectors, and then the elastic connector is combined with the center core to "anchor" the conductors on the center core. After the cable is stretched and bent to restore its original shape, the elastic connector with one end fixedly connected to the center core can pull the dislocated conductor through the elastic connection action, so that the conductor returns to its original position. During the stretching and bending process of the cable, the inner sheath of the cable can maintain structural stability through the double-layer steel belt armor, and the inner sheath is supported by the support body arranged on the center core from the inside, ensuring the stability of the cable structure, thereby avoiding the life of the energy storage cable being reduced due to stretching and bending.

[0024] 2. In this long-life, environmentally friendly energy storage cable processing method, the elastic connector is made of highly elastic environmentally friendly rubber, which is non-toxic and harmless and has little impact on the environment. The elastic connector is grouped according to the number of conductors. The number of elastic connectors in each group is consistent with the number of conductors, and the main ring in each group is placed on different conductors in a clockwise or counterclockwise manner. This can facilitate the elastic connector to be combined around the center core, reducing the difficulty of operation, and ensure the connection strength between adjacent conductors.

[0025] 3. In the processing method of the high-life environmentally friendly energy storage cable, during the pressing process of the pressure plate, the pressure plate drives the upper shell to slide down along the second end plate until the two upper shells are closed to cover the top of the center core, and the shaft sleeve passes through the limiting groove. Since the shaft sleeve is restricted by the limiting groove, when the pressure plate drives the connecting pin to be clamped into the shaft sleeve, the shaft sleeve cannot move so that the connecting pin can be smoothly clamped, thereby reducing the processing difficulty.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0043] See also Figure 1-11 As shown, the purpose of this embodiment is to provide a long-life environmentally friendly energy storage cable processing method, comprising the following steps:

[0044] S1. Insert the conductive core 111 into the insulating tube 113, keep the central axis of the conductive core 111 and the insulating tube 113 aligned, then inject refractory material into the insulating tube 113, cool it to form a refractory layer 112, and then produce the electric conductor 11. Then, fix at least three electric conductors 11 together through multiple elastic connectors 12, wherein:

[0045] In the present invention, taking the use of three electrical conductors 11 to make a cable as an example, the elastic connector 12 includes a main ring 121, and the two ends of the main ring 121 are respectively connected to the first auxiliary ring 123a and the second auxiliary ring 123b through a connecting belt 122. The main ring 121, the first auxiliary ring 123a, and the second auxiliary ring 123b are respectively put on the electrical conductor 11. The main ring 121 itself is fixed on one electrical conductor 11, and the first auxiliary ring 123a and the second auxiliary ring 123b are respectively fixed on the other two electrical conductors 11. The three electrical conductors 11 are fixedly connected by the connected connecting belts 122.

[0046] The elastic connector 12 is made of highly elastic environmentally friendly rubber, and environmentally friendly silicone rubber is preferably used in the present invention. A slot 114 with a trapezoidal cross-section is provided on the outer wall of the insulating tube 113. The main ring 121, the first auxiliary ring 123a, and the second auxiliary ring 123b are all trapezoidal in cross-section and engage with the slot 114. By engaging with each other, the elastic connector 12 and the conductor 11 can be fixedly connected to each other, thereby preventing relative sliding between the elastic connector 12 and the conductor 11. When the cable is stretched and bent, the conductor 11 can be reset when the cable returns to its original shape through the elastic connection of the elastic connector 12, thereby avoiding the problem that the internal structure of the cable is affected by the misalignment of the conductor 11.

[0047] It is worth noting that when multiple electrical conductors 11 are fixedly connected through multiple elastic connectors 12, the multiple elastic connectors 12 are grouped according to the number of electrical conductors 11, and the number of elastic connectors 12 in each group is consistent with the number of electrical conductors 11, and the main ring 121 in each group is put on different electrical conductors 11 in a clockwise or counterclockwise manner. Taking the production of a cable with three electrical conductors 11 as an example, the multiple elastic connectors 12 are divided into groups of three and arranged from front to back or from back to front. The main ring 121 of the first elastic connector 12 is put on the electrical conductor 11 located at the lower right, the main ring 121 of the second elastic connector 12 is put on the electrical conductor 11 located at the lower left, and the main ring 121 of the third elastic connector 12 is put on the upper electrical conductor 11. The reason for this arrangement is that if the main ring 121, the first secondary ring 123a, and the second secondary ring 123b are connected in pairs through the connecting belt 122, a complete The whole circular ring structure has a long total length of the cable, and it is difficult to insert the center core 13 from one end of the conductor 11 to the other end, and it is not conducive to the combination of the elastic connector 12 and the center core 13. Therefore, the elastic connector 12 is arranged in the form of a main ring 121 connecting the two secondary rings through a connecting belt 122. This makes it convenient for the elastic connector 12 to surround the center core 13 and combine. However, when this arrangement encounters cable stretching and bending, the conductor 11 fixed by the main ring 121 and the adjacent conductor 11 maintain a high connection strength through the connecting belt 122, while the conductors 11 fixed by the two secondary rings have no direct connection structure and are only indirectly connected through the main ring 121, which has a low connection strength. When the cable returns to its original state, the conductors 11 fixed by the two secondary rings cannot be completely reset, and there is a misalignment, which affects the cable life. Therefore, a plurality of elastic connectors 12 are grouped and arranged in a clockwise and counterclockwise manner to circumvent this problem.

[0048] S2. Clamp one end of the center core 13 through the fixed body 21, then pass the other end of the center core 13 through the embedded body 22, and combine the elastic connecting body 12 and the center core 13 through the embedded body 22.

[0049] Specifically, a plurality of sleeves 131 are provided on the surface of the center core 13, a sleeve belt 124 is connected to the surface of the second sub-ring 123b, and the end of the sleeve belt 124 is sleeved and matched with the sleeve 131. A connecting pin 125 is provided on the surface of the first sub-ring 123a, and the end of the connecting pin 125 is snap-fitted with the sleeve 131. Through the sleeve and snap-fitting method, the elastic connector 12 and the fixed electric conductor 11 can be "anchored" on the center core 13. When the cable returns to its original shape after being stretched and bent, the electric conductor 11 and the elastic connector 12 that have undergone relative displacement can be restored to their original position with the help of the center core 13.

[0050] The fixed body 21 includes a horizontal plate 211 and a vertical plate 212 provided at one end of the horizontal plate 211. A pair of clamping plates 213 are plugged into and fitted on the vertical plate 212. A screw shaft 214 is provided on the outer wall of the vertical plate 212 and is threadedly connected to the clamping plates 213. The clamping plates 213 are provided with a roller 215 for clamping one end of the center line core 13.

[0051] The embedded body 22 includes a slide plate 221 and a pressure plate 222 that is plugged into and matched with the slide plate 221. The slide plate 221 is slidably connected to the slide rail set on the top of the cross plate 211. The top of the slide plate 221 is provided with a bottom groove 223 for placing the center core 13. The two ends of the pressure plate 222 are provided with a first end plate 224 for rotation connection. The two ends of the slide plate 221 are provided with a rotating shaft 225 for rotation connection. The rotating shaft 225 passes through the first end plate 224. The rotating shaft 225 is slidably connected to the first end plate 224. By rotating the screw shaft 214, the clamping plate 213 drives the roller 215 to clamp and fix one end of the center core 13. The other end passes through the bottom groove 223, so that the center core 13 is partially located in the bottom groove 223. The angle of the center core 13 is adjusted so that the sleeve 131 faces upward. The main ring 121, the first auxiliary ring 123a, and the second auxiliary ring 123b are placed around the center core 13. After the sleeve 124 is put on the sleeve 131, the first auxiliary ring 123a is placed in the groove formed at the bottom of the pressure plate 222, so that the connecting pin 125 faces the sleeve 131 below. The rotating shaft 225 is held and rotated downward, driving the pressure plate 222 and then the connecting pin 125 to engage with the sleeve 131, thereby completing the connection between the elastic connector 12 and the center core 13.

[0052] Furthermore, second end plates 226 are symmetrically provided at the top of the slide plate 221 at both ends of the bottom groove 223, and an upper shell 227 is slidably connected to the second end plate 226. The upper shell 227 is connected to the bottom of the pressure plate 222 by a spring provided on the surface. The upper shell 227 is an arc shell for covering the top of the center line core 13, and a limiting groove is opened on the arc shell for exposing the shaft sleeve 131. When the pressure plate 222 is pressed down, the pressure plate 222 drives the upper shell 227 to slide down along the second end plate 226 until the two upper shells 227 are closed to cover the top of the center line core 13, and the shaft sleeve 131 passes through the limiting groove. Since the shaft sleeve 131 is restricted by the limiting groove, when the pressure plate 222 drives the connecting pin 125 to be clamped into the shaft sleeve 131, the shaft sleeve 131 cannot move so that the connecting pin 125 can be smoothly clamped, thereby reducing the processing difficulty;

[0053] S3. Arrange multiple supports 14 on the center core 13 to form a composite mandrel, insert the composite mandrel into the inner sheath 15 and connect it to the inner wall of the inner sheath 15. The specific process is as follows:

[0054] The number of the support bodies 14 is consistent with the number of the elastic connectors 12, and the support bodies 14 and the elastic connectors 12 are spaced apart and arranged on the conductor 11. The support body 14 includes a pair of half rings 141 for plugging in. The half rings 141 are provided with support arms 142 for contacting the inner wall of the inner sheath 15. By putting the two half rings 141 on the center core 13 and plugging them together into one, the installation of the support body 14 can be completed. The inner wall of the inner sheath 15 is provided with a sleeve groove 151, and the end of the support arm 142 is located in the sleeve groove 151. The end of the arm 142 is slidably connected to the sleeve groove 151. By placing the end of the support arm 142 in the sleeve groove 151, it can not only support the inner sheath 15 and the outer structure, but also ensure that the center core 13 is always located in the middle of the cable. Before inserting the composite mandrel into the inner sheath 15, align the end of the support arm 142 with the sleeve groove 151 and insert it, then place the composite mandrel into the inner sheath 15. After the composite mandrel is inserted into the inner sheath 15, fill the inner sheath 15 with a material used to fill the gap between the inner sheath 15 and the composite mandrel, that is, a filling layer 152;

[0055] S4. After the inner layer steel belt armor 16 and the outer layer steel belt armor 17 are sequentially wound around the outer periphery of the inner sheath 15, the shielding sleeve 18 and the outer sheath 19 are sequentially covered on the outer layer of the outer layer steel belt armor 17 to produce an energy storage cable. The winding directions of the inner layer steel belt armor 16 and the outer layer steel belt armor 17 are opposite, which can effectively improve the mechanical strength of the cable and reduce the probability of damage to the cable during use.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
