[0018] The embedded body includes a slide plate and a pressure plate that is plugged into and matched with the slide plate up and down. The slide plate 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 slide plate.

[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, a plurality of conductors are fixedly connected to a plurality of 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 to restore the conductor to its original position. During the stretching and bending process of the cable, the inner part of the cable can maintain structural stability through the double-layer steel belt armor from the outer periphery of the inner sheath, and the inner side of the inner sheath is supported by a support body arranged on the center core, thereby ensuring the stability of the cable structure and avoiding the life of the energy storage cable from being reduced due to stretching and bending.

[0024] 2. In the processing method of the high-life environmentally friendly energy storage cable, 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 electrical conductors. The number of elastic connectors in each group is consistent with the number of electrical conductors, and the main ring in each group is arranged on different electrical 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 electrical conductors.

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

[0043] See also Figure 1-11 As shown, the purpose of this embodiment is to provide a method for processing a long-life environmentally friendly energy storage cable, 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 coincident, then inject refractory material into the insulating tube 113, and after cooling, form a refractory layer 112 to produce an electric conductor 11, and then fix and connect at least three electric conductors 11 through multiple elastic connectors 12, wherein:

[0045] In the present invention, taking the use of three electric 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 sleeved on the electric conductors 11. The main ring 121 itself is fixed on one electric conductor 11, and the first auxiliary ring 123a and the second auxiliary ring 123b are respectively fixed on the other two electric conductors 11. The three electric conductors 11 are fixedly connected by the connected connecting belts 122.

[0046] The elastic connector 12 is a 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 are engaged with the slot 114. Through the engaging and engaging method, the fixed connection between the elastic connector 12 and the conductor 11 can be ensured, and relative sliding between the elastic connector 12 and the conductor 11 can be avoided. When the cable is stretched and bent, the conductor 11 can be reset when the cable is restored to its original state through the elastic connection of the elastic connector 12, thereby avoiding the problem that the internal structure of the cable is affected due to 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, 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 set on different electrical conductors 11 in a clockwise or counterclockwise manner. Taking the production of cables with three electrical conductors 11 as an example, the multiple elastic connectors 12 are divided into groups of three, and are set from front to back or from back to front. The main ring 121 of the first elastic connector 12 is set on the electrical conductor 11 located at the lower right, the main ring 121 of the second elastic connector 12 is set on the electrical conductor 11 located at the lower left, and the main ring 121 of the third elastic connector 12 is set 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, due to the long total length of the cable, 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, so the elastic connector 12 is set in the form of a main ring 121 connecting two secondary rings through a connecting belt 122, so that it is convenient for the elastic connector 12 to surround the center core 13 for combination, but this arrangement encounters the 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, and there is no direct connection structure between the conductors 11 fixed by the two secondary rings, and only maintains an indirect connection through the main ring 121, and the connection strength is low. 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, the multiple elastic connectors 12 are grouped and arranged in a clockwise and counterclockwise manner to avoid it;

[0048] S2. Clamp one end of the center line core 13 through the fixed body 21, then pass the other end of the center line core 13 through the embedded body 22, and combine the elastic connecting body 12 with the center line 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 conductor 11 can be "anchored" on the center core 13. When the cable returns to its original state after being stretched and bent, the conductor 11 and the elastic connector 12 that have undergone relative displacement can return 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 arranged at one end of the horizontal plate 211. A pair of clamping plates 213 are plugged and matched on the vertical plate 212. A screw shaft 214 threadedly connected to the clamping plate 213 is arranged on the outer wall of the vertical plate 212. The clamping plate 213 is 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 pressing plate 222 which is plugged and matched with the slide plate 221 up and down. 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 line core 13. The two ends of the pressing plate 222 are provided with a first end plate 224 which is rotatably connected. The two ends of the slide plate 221 are provided with a rotating shaft 225 which is rotatably connected. The rotating shaft 225 passes through the first end plate 224. The rotating shaft 225 is slidably connected with the first end plate 224. After the clamping plate 213 drives the roller 215 to clamp and fix one end of the center line core 13 by rotating the screw shaft 214, the center line core 13 is fixed. The other end passes through the bottom groove 223, so that the center core 13 is partially located in the bottom groove 223, and the angle of the center core 13 is adjusted so that the sleeve 131 faces upward, and the main ring 121, the first auxiliary ring 123a, and the second auxiliary ring 123b are placed around the center core 13, and the sleeve 124 is put on the sleeve 131, and then the first auxiliary ring 123a is placed in the groove opened at the bottom of the pressing plate 222, so that the connecting pin 125 faces the sleeve 131 below, and the rotating shaft 225 is held and rotated downward, driving the pressing plate 222 and then driving the connecting pin 125 to be stuck in the sleeve 131, so that the elastic connector 12 and the center core 13 are combined.

[0052] Furthermore, second end plates 226 are symmetrically arranged 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 pressing plate 222 through a spring arranged on the surface. The upper shell 227 is an arc-shaped shell for covering the top of the center line core 13, and a limiting groove for exposing the shaft sleeve 131 is opened on the arc-shaped shell. When the pressing plate 222 is pressed down, the pressing 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 pressing 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, multiple supports 14 are arranged on the center core 13 to form a composite mandrel, and the composite mandrel is inserted into the inner sheath 15 and connected 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 arranged on the conductor 11 at intervals. The support body 14 includes a pair of half rings 141 for plugging and matching. The half rings 141 are provided with support arms 142 for contacting the inner wall of the inner sheath 15. The installation of the support body 14 can be completed by putting the two half rings 141 on the center line core 13 and combining them into one in a plug-in manner. 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 support arm 142 is provided with a sleeve groove 151, and the support arm 142 is provided with a 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, the inner sheath 15 and the outer structure can be supported, and the center core 13 can be ensured to be 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 put 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, i.e., 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 by the above embodiments.
