DETAILED DESCRIPTION

[0021] 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.

[0022] Example 1, please refer to Figure 1-Figure 2 , the present invention provides the following technical solution: A superconducting cable includes a core wire 100, a superconducting braid 200, and an insulating layer 300. The superconducting braid 200 is woven onto the surface of the core wire 100, and the insulating layer 300 is wrapped around the surface of the superconducting braid 200. The superconducting braid 200 is woven from X superconducting filaments 201 and Y carbon fibers 202, where Y ≤ X. A hot-melt adhesive film is spirally wrapped around the surfaces of the Y carbon fibers 202.

[0023] The present invention also provides a method for preparing the superconducting cable, comprising: S1. Prepare the core wire 100 and the X superconducting filaments 201 and Y carbon fibers 202 for weaving on the surface of the core wire 100, where Y≤X; S2. A hot melt adhesive film is spirally wound on the surface of the Y-root carbon fiber 202; S3. The core wire 100, the superconducting filament 201 and the carbon fiber 202 are placed in a heating environment, and under heating conditions, the X superconducting filaments 201 and the Y carbon fiber 202 wrapped with a hot melt adhesive film are woven on the surface of the core wire 100 to obtain a superconducting cable body; S4. The superconducting cable body is cooled by transporting the heated braided cable; S5. After cooling, the superconducting braided layer 200 formed by the superconducting filaments 201 and the carbon fibers 202 on the surface of the superconducting cable body is wrapped with the insulating layer 300.

[0024] Example 2: Figure 3 As shown, the present invention also provides the following technical solution: A superconducting cable preparation device includes a coaxially assembled core wire feeding mechanism and a wire braiding mechanism; like Figure 9 and Figure 10 As shown, the core wire feeding mechanism includes a central tube 1 that can pass the core wire 100, and a heating mechanism 11 is provided at the outlet end of the central tube 1; the heating mechanism 11 is an electric heating sleeve with a bowl-shaped structure; a positioning ring 12 is also fixed to the outside of the central tube 1, and the positioning ring 12 is located between the heating mechanism 11 and the annular guide rail 2.

[0025] like Figure 3 and Figure 4As shown, the wire braiding mechanism includes an annular guide rail 2 coaxially fitted to the outside of the central tube 1 and N wire release mechanisms 3 capable of moving along the annular guide rail 2. The annular guide rail 2 can rotate around its central axis and is provided with a plurality of grooves. A turntable is rotatably mounted in each groove, and at least two wire release mechanisms 3 are mounted on each turntable. Thus, the movement of the N wire release mechanisms 3 is achieved by utilizing the rotation of the annular guide rail 2 and the rotation of the turntable. Specifically, each wire release mechanism 3 can revolve around the central axis of the turntable and around the central axis of the annular guide rail 2. The N wire release mechanisms 3 include X superconducting wire release mechanisms and Y carbon fiber release mechanisms, where Y≤X. Each wire release mechanism 3 includes a mounting frame 31 and a wire guide sleeve 32 disposed on the mounting frame 31. The wire guide sleeve 32 of the carbon fiber release mechanism is provided with a rotatably connected hot melt adhesive film winding mechanism 4. Among them, the hot melt adhesive film winding mechanism 4 is configured to spirally wind the hot melt adhesive film on the surface of the carbon fiber 202, and the heating mechanism 11 is configured to heat the hot melt adhesive film at the weaving point of the core wire 100, superconducting wire 201 and carbon fiber 202 at the outlet end of the central tube 1.

[0026] In the present invention, a wire roller 33 is rotatably installed on the mounting frame 31, a guide rod 34 is provided on one side of the wire roller 33, a first guide wheel 35 is provided on one side of the guide rod 34, and a second guide wheel 36 is provided on the side of the first guide wheel 35 near the bottom of the mounting frame 31. The wire roller 33 releases the superconducting wire 201 or carbon fiber 202 toward the wire lead-out sleeve 32, and the released superconducting wire 201 or carbon fiber 202 passes around the guide rod 34, the first guide wheel 35 and the second guide wheel 36 in sequence.

[0027] In the present invention, the hot melt adhesive film winding mechanism 4 includes an inner sleeve 41 and an outer sleeve 42 coaxially fixed to the inside of the wire guide sleeve 32 through a chassis, and the outer sleeve 42 has mounting holes symmetrically opened on the side wall. A central channel for the superconducting wire 201 or carbon fiber 202 to pass through the center of the inner sleeve 41 is provided, and a film inlet hole for the hot melt adhesive film to pass through is opened on the side wall of the inner sleeve 41. A hot melt adhesive film roller 43 passes through the mounting hole, and the center of the hot melt adhesive film roller 43 is rotatably connected to a mounting rod 44. One end of the mounting rod 44 is fixed with a threaded connector 45 that can be connected to the inner sleeve 41, and the other end is rotatably connected to a limiting column 46; a limiting screw 47 that can be inserted into the limiting column 46 is connected to the chassis.

[0028] The installation process before hot melt adhesive film winding is as follows: the hot melt adhesive film on the hot melt adhesive film roller 43 is pulled through the film inlet hole of the outer sleeve 42 and into the central channel of the outer sleeve 42. The hot melt adhesive film roller 43 is then inserted into the installation hole. The installation rod 44 and the threaded connector 45 are rotated to connect one end of the hot melt adhesive film roller 43 to the inner sleeve 41. The limiting post 46 and the limiting screw 47 are rotated to ensure that the limiting screw 47 can be inserted into the limiting post 46, thus completing the position limit of the other end of the hot melt adhesive film roller 43. The silk thread released by the corresponding silk thread release mechanism 3 is pulled through the central channel of the inner sleeve 41, and the hot melt adhesive film in the central channel is fixed to the surface of the silk thread.

[0029] In the present invention, a driven gear 48 is fixedly mounted on the outer side of the chassis, and a driving gear 49 driven by a micromotor is mounted on the mounting frame 31. The driving gear 49 engages one side of the driven gear 48. As the superconducting braid 200 is woven and formed, the wire is fed from the interior of the central channel of the inner sleeve 41 to the weaving area. As the wire is fed, the micromotor drives the driving gear 49 to rotate, which in turn drives the driven gear 48 to rotate, thereby achieving synchronous rotation of the inner sleeve 41 and the outer sleeve 42. During this rotation, the hot melt adhesive film is spirally wrapped around the surface of the wire. During the spiral winding process, the feeding of the wire exerts a pulling effect on the hot melt adhesive film, thereby pulling the hot melt adhesive film roller 43 to rotate, thereby releasing the hot melt adhesive film.

[0030] like Figure 7 and Figure 8 As shown, four hot melt adhesive film rollers 43 are arranged in an array. Therefore, when connecting four hot melt adhesive films to the silk thread, the four hot melt adhesive films are arranged side by side along the axial direction of the silk thread, thereby ensuring that each hot melt adhesive film can be spirally wound.

[0031] In addition, as weaving continues, the hot melt adhesive film on the hot melt adhesive film roller 43 gradually decreases. When the hot melt adhesive film decreases to the point where the hot melt adhesive film roller 43 needs to be replaced, the tail end of the hot melt adhesive film on the old hot melt adhesive film roller 43 is first fixed to the head end of the hot melt adhesive film on the new hot melt adhesive film roller 43. Then, the old hot melt adhesive film roller 43 is removed and the new hot melt adhesive film roller 43 is installed. This completes the replacement and ensures that the hot melt adhesive film can continue to spirally wind. Regarding the removal of the old hot melt adhesive film roller 43, the installation process is reversed. That is, first rotate the limit screw 47 to remove the limit between the limit screw 47 and the limit column 46, then rotate the installation rod 44 to remove the connection between the threaded connector 45 and the inner sleeve 41, and finally, pull the old hot melt adhesive film roller 43 out of the installation hole. The installation operation of the new hot melt adhesive film roller 43 is the same as above.

[0032] The present invention also provides a method for preparing a superconducting cable using the above-mentioned superconducting cable preparation device, comprising: S1 provides a superconducting cable preparation device including a core wire supply mechanism and a wire braiding mechanism, and the core wire supply mechanism and the wire braiding mechanism are coaxially assembled; S2. The core wire 100 is transported from the central tube 1 at the center; S3. N wire release mechanism 3 delivers X superconducting wires 201 and Y carbon fibers 202, where Y≤X; S4 at least for releasing the carbon fiber 202 of the wire release mechanism 3 is installed in the rotatable hot melt adhesive film winding mechanism 4; the superconducting filament 201 and the carbon fiber 202 are passed from the inside of the inner sleeve 41, wherein the hot melt adhesive film winding mechanism 4 is at least Y root carbon fiber 202 surface spirally wound hot melt adhesive film; S5. By means of N wire release mechanisms 3, movement along the annular guide rail 2 causes X superconducting wires 201 and Y carbon fibers 202 wrapped with a hot melt adhesive film to be woven onto the surface of the core wire 100; S6. Using the heating mechanism 11 to heat the hot melt adhesive film at the braided core wire 100, the superconducting filament 201 and the carbon fiber 202; S7. The braided superconducting cable is cooled in front of the heating mechanism 11 along the conveying direction of the superconducting cable. After cooling, the insulating layer 300 is wrapped around the superconducting braided layer 200 formed by the superconducting filaments 201 and the carbon fibers 202 .

[0033] Regarding the preparation of the insulation layer 300, a superconducting cable preparation device with the same structure as described above can be added. A certain natural cooling zone is reserved between the two superconducting cable preparation devices. After the superconducting braided layer 200 is braided and formed, it is transported and naturally cooled in the natural cooling zone. Specifically, the central tube 1 of the core wire feeding mechanism is used to transport the core wire 100 with the superconducting braided layer 200 braided on its surface, and the heating mechanism 11 is not activated or removed. The corresponding wire braiding mechanism is used to braid the insulation layer 300, that is, each wire release mechanism 3 is not provided or activated, and the hot melt adhesive film winding mechanism 4 is used to transport the insulating fiber and weave the insulating fiber onto the surface of the superconducting braided layer 200. For example, the insulation layer 300 can be braided using multiple polyethylene terephthalate fibers, which can provide excellent electrical insulation, fatigue resistance, and friction resistance.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be embraced herein, and any reference signs in the claims should not be construed as limiting the claims to which they relate.
