Steel wire rope fixing ring and manufacturing method thereof
The present application relates to a kind of steel wire rope fixing ring in the technical field of protective net production, which is self-wound by single spiral strand of steel wire rope.Formed when preparing, including the following steps: (1) cut steel wire rope according to target length;(2) the cut steel wire rope is disassembled into multiple spiral strands;(3) take one of the spiral strands, bend one end into a single strand ring, the diameter of the single strand ring is equal to the design diameter of the target steel wire rope fixing ring;(4) based on the single strand ring, self-winding is carried out along the ring body direction with the same spiral strand until the spiral strand is wound;(5) lock the strand head at the winding end, and the steel wire rope fixing ring is prepared.The annular protective net made of the above steel wire rope fixing ring has excellent impact energy performance.

The invention discloses a composite material with longitudinally distributed basalt fibers as well as a preparation method and application of the composite material. The composite material comprises at least one layer of base plate, wherein the base plate is formed by closely paving a plurality of prismatic unit bodies which are consistent in thickness and have regular polygonal cross sections; the unit bodies in the composite material are fixed into a whole through an adhesive; the unit body is composed of a plurality of basalt fibers which are longitudinally arranged; the fiber direction of the basalt fibers in the unit bodies is the same as the axis direction of the unit bodies and is perpendicular to the plate face of the base plate obtained by tiling the unit bodies. The core of the bulletproof armor plate is that the distribution direction of basalt fibers is changed from the radial direction to the axial direction, so that the problem that the radial pressure resistance is insufficient when traditional fibers are transversely distributed is solved, and the prepared bulletproof armor plate can convert impact force of bullets into pressure on the axial direction of the fibers; the extremely high axial compressive strength of the basalt fibers is fully utilized, so that the bulletproof efficiency is remarkably improved, and the light weight of the armor is achieved.

This invention belongs to the field of civil defense engineering and explosion-proof protection technology, and relates to a polyurea-coated, panelless civil defense device, including a load-bearing outer panel, a reinforcing frame, elastic damping connectors, an internal cast-in-place body, an arc-shaped elastic support rod, and a support plate. The support plate's inner side contacts the arc-shaped protruding surface of the arc-shaped elastic support rod, forcing the rod to undergo elastic compression deformation. The arc-shaped structure of the support rod produces a progressive stiffness response under pressure: initially, the arc-shaped structure is easily deformable, providing a large displacement stroke to absorb energy; as the compression increases, the stiffness of the support rod gradually increases, effectively suppressing excessive deformation. During deformation, the arc-shaped elastic support rod generates a reaction force on the reinforcing frame, which is evenly distributed to the internal cast-in-place body through the three-dimensional mesh structure of the reinforcing frame. Its structural design is scientifically sound, easy to use, provides excellent protection, and is environmentally friendly.
