Description

TECHNICAL FIELD

[0001] The utility model belongs to superconducting cable preparation technical field, especially relate to a device for preparing stacked high temperature superconducting degaussing cable. BACKGROUND

[0002] Superconducting material zero resistance effect has the property of lossless transport current, and the superconducting cable technology based on superconducting material can reduce the loss in power transmission and improve transmission efficiency, and the great economic significance it brings makes it become a high-tech that is focused on research and application in public infrastructure and industrial fields in the world today. The high temperature superconducting degaussing cable uses superconducting material to become superconducting state under its working temperature range, has the characteristics of zero resistance and high current-carrying capacity, and can produce strong magnetic field due to its ultra-high current density, and can be used for degaussing in places such as ships and degaussing stations, fully exerting the advantages of strong magnetic field of second-generation high temperature superconducting material.

[0003] In the prior art, during the preparation of the superconducting degaussing cable, the superconducting tape is first twisted after being gathered by a mold, and then led to a welding area for welding. The above preparation method has the following problems:

[0004] (1) In the twisting process of the stacked superconducting degaussing cable, the superconducting tape is currently split according to the stacked structure of the cable, and then gathered into a mold that meets the structural requirements of the cable according to the gathering point position. After the gathering, the superconducting tape is gradually twisted along the axial direction with the traction of the equipment. This method can completely conform to the design principle of the cable structure, complete the double-sided separated gathering according to the stacked structure, but it cannot guarantee the quantification of the twisting angle, and is not suitable for the twisting of superconducting tapes with different angles. Therefore, it is difficult to obtain quantitative process data, and it is difficult to provide a better direction and route for process improvement. In addition, the current mold can only provide axial angle rotation function, and cannot provide longitudinal length control function;

[0005] (2) The static angle and reserved length of the current lead at the end of the cable cannot be effectively controlled in the current mold, and cannot assist the next welding work of the current lead, resulting in that the angle of the current lead part is completely controlled manually, the method is not scientific enough, the data is not rigorous enough, and the welding quality of the current lead is unstable;

[0006] (3) The current mold cannot accurately control the pre-tightening force of the superconducting degaussing cable in the static state, and completely relies on the tension control system of the cable production equipment in the dynamic state to feedback the tension of the superconducting tape. When the equipment traction tension changes slowly and gradually, the pre-tightening force of the superconducting degaussing cable is not enough, which may cause the superconducting tape to derail, affecting the production stability and efficiency of the superconducting degaussing cable. With the relaxation of the pre-tightening force, the superconducting tape may be folded and twisted, resulting in performance degradation of the superconducting tape, and further affecting the electrical and mechanical properties of the superconducting degaussing cable.

[0038] Reference Figure 1 and Figure 2 is a structural schematic diagram of the present application, providing a device for preparing a stacked high-temperature superconducting magnetic field cancellation cable, comprising a rack 1, a front mold mechanism 2 and a rear mold mechanism 3 arranged on the rack 1.

[0039] As shown in Figure 3 , the front mold mechanism 2 is used to control the twisting angle of the superconducting tape, comprising a rotating disc 2-1 rotatably installed on the rack 1 and a positioning assembly for limiting the rotating angle of the rotating disc 2-1, the axis of the rotating disc 2-1 is arranged along the extension direction of the superconducting tape, and a plurality of first tape holes 2-1a for the superconducting tape to pass through in the thickness direction and a first skeleton slot 2-1b for the cable skeleton 6 to pass through are arranged on the rotating disc 2-1.

[0040] As shown in Figure 4 , in order to facilitate the installation of the rotating disc 2-1, the front mold mechanism 2 further comprises a support frame fixed on the rack 1, and the rotating disc 2-1 is rotatably connected with the support frame. Specifically, the support frame comprises a column 2-5 fixed vertically on the rack 1 and a support shaft 2-6 fixed on the upper end of the column 2-5, a cable skeleton hole for the cable skeleton 6 to pass through is arranged axially on the support shaft 2-6, and the rotating disc 2-1 is rotatably supported on the support shaft 2-6.

[0041] In the present example, a connecting assembly is arranged on one side of the rotating disc 2-1 in the thickness direction and is rotatably connected with the support shaft 2-6. The connecting assembly includes a connecting block 2-7 fixed on the rotating disc 2-1 and a support ring 2-8 fixedly connected with the connecting block 2-7. The support ring 2-8 is rotatably arranged on the support shaft 2-6 via a bearing 2-9. Specifically, the support shaft 2-6 is tightly connected with the inner ring of the bearing 2-9, and the support ring 2-8 is tightly connected with the outer ring of the bearing 2-9, so as to realize the rotational connection between the support ring 2-8 and the support shaft 2-6. The connecting block 2-7 is provided with an avoiding hole corresponding to the first skeleton through slot 2-1b. The cable skeleton 6 extends to the second skeleton through slot 3-2b of the rear mold mechanism 3 after sequentially passing through the cable skeleton through hole, the avoiding hole and the first skeleton through slot 2-1b.

[0042] The positioning assembly includes a support seat 2-2 fixed on the rack 1 and an electromagnet 2-3 installed on the upper end of the support seat 2-2, wherein the electromagnet 2-3 is connected with a power supply.

For example, one metal block 2-4 is arranged on the rotating disc every 15 degrees to display the angle of rotation. The metal block 2-4 can be magnetically adsorbed with the electromagnet 2-3. When the rotating disc 2-1 is rotated by a certain angle, the electromagnet 2-3 is powered, and the metal block 2-4 is adsorbed on the electromagnet 2-3, thereby realizing the positioning of the rotating disc 2-1, i.e. the positioning of the twisting angle of the superconducting tape.

When the superconducting cable is twisted, the position of the limiting seat on the guide rail 4 can be adjusted, and the limiting seat is positioned on the guide rail 4, so as to adjust the distance between the limiting seat and the rotating disc 2-1, thereby adjusting the welding length of the cable end lead, and at the same time, the superconducting tape is kept in a certain pre-tightening force.

[0047] The working principle of the utility model is:

[0048] The superconducting tape is wound by the unwinding mechanism, enters the first tape collecting hole 2-1a on the rotating disc 2-1 of the front die mechanism 2, then extends to the second tape collecting hole 3-2a on the limiting seat of the rear die mechanism 3, then enters the winding mechanism through the welding area, the twisting angle of the superconducting tape is adjusted by rotating the rotating disc 2-1, and the rotating disc 2-1 is positioned at the required angle through the positioning assembly, the length of the superconducting tape and the welding length of the lead end are adjusted by moving the position of the limiting seat on the guide rail 4 and locking, and finally the superconducting tape is twisted on the cable skeleton 6 to obtain the superconducting cable.
