This invention relates to a high-temperature superconducting cable, comprising: a metal skeleton, high-temperature superconducting tape, impregnated filler, a conductive metal layer, and a metal armor layer; a central cooling channel is provided in the center of the metal skeleton; the high-temperature superconducting tape is stacked into strands, with the entire strand spirally wound tightly against the metal skeleton; a conductive metal layer is wound around the outer side of the high-temperature superconducting tape, and a metal armor layer is also provided; the impregnated filler is filled into the gaps between each strand of the high-temperature superconducting tape using a vacuum pressure impregnation process. Compared with the prior art, in this invention, the high-temperature superconducting tape is stacked into strands and wound on the metal skeleton, and the neatly stacked tape is less susceptible to mechanical damage; there are gaps between the strands of the high-temperature superconducting tape, and the size of the gaps can be changed when the cable is bent, so the high-temperature superconducting tape is less likely to be damaged by excessive stress when the cable is bent; after the cable is bent, the gaps between the strands of the high-temperature superconducting tape can be filled by vacuum pressure impregnation, improving the thermal conductivity and mechanical strength of the cable.

The utility model discloses a radiation unit assembly. The radiation unit assembly comprises a mounting seat, a feed bottom plate, two radiation arms and two feed sheets, the two radiation arms are orthogonally arranged at the top of the mounting seat, the top of the mounting seat is provided with a convex insertion column, the side surface of the insertion column is provided with at least one elastic clamping arm, and the radiation arms are provided with insertion holes matched with the insertion column; the two feed sheets are orthogonally arranged in the mounting seat; the feed bottom plate is arranged at the bottom of the mounting seat; one end of each of the two feed sheets is in feed connection with the radiation panel, and the other end of each of the two feed sheets is in feed connection with the feed base plate. When the radiation arm and the mounting seat of the radiation unit assembly are assembled, the insertion hole of the radiation arm is aligned with the insertion column of the mounting seat, and then the insertion column is inserted into the insertion hole until the elastic clamping arm passes through the insertion hole and abuts against the upper surface of the radiation arm, so that the assembly can be completed, additional fasteners are not needed, the assembly process is simple and convenient, and the assembly efficiency is improved. And the radiation arms do not need to be greatly bent, so that the radiation arms are not easy to deform.

The invention discloses aluminum magnesium alloy surface treatment equipment and method, and relates to the technical field of aluminum magnesium alloy surface treatment.The aluminum magnesium alloy surface treatment equipment comprises a liquid box and a material basket, the liquid box is fixedly arranged at the bottom end in an outer box body, an anodic oxidation component is arranged in the liquid box, and conveying belts are symmetrically arranged above the liquid box; and a plurality of locking parts fixedly connected with the material basket are arranged on the two conveying belts at equal intervals, each locking part comprises a mounting box, the mounting box is fixedly arranged at one end of the second inner spline shaft, a supporting mechanism is arranged in the outer box body, a drying mechanism is arranged in the drying box, and a rotating mechanism is arranged in the outer box body. A plurality of locking parts are arranged on the two conveying belts at equal intervals, so that the conveying belts can drive the material basket to move, and the second friction disc is in friction fit with the first friction disc, so that bubbles are reduced when aluminum magnesium alloy is subjected to anodic oxide film processing, and meanwhile, the aluminum magnesium alloy is uniformly covered with an oxide film.

The utility model relates to the technical field of strip edge cloth, and discloses a braid strip edge with strong retractility, which structurally comprises an elastic layer, a breathable layer and an open pore. The high-elasticity first core-spun yarn and the high-elasticity second core-spun yarn are combined and knitted to form the rib stitch through the front stitch wale and the back stitch wale, and the front stitches and the back stitches are not in the same plane, so that sinker loops for connecting the front stitches and the back stitches have large bending and torsion; according to the woven ribbon, the small edges of the woven ribbon have large transverse stretchability and high rebound resilience by means of the rib stitches formed through weaving, the edges of the woven ribbon are not prone to curling and loosening through the double-face structure formed through weaving of the rib stitches, the woven ribbon is soft and comfortable, and the garment market is greatly enriched and beautified.
