Description

TECHNICAL FIELD

[0001] The utility model relates to perimeter security equipment technical field, concretely is a kind of through continuous airfoil design and multi-angle thorn structure improves shear resistance and topographic adaptability Ω type continuous airfoil multi-angle thorn grating net, it is applicable to perimeter protection of high security level area such as coastal defense, airport, prison etc. BACKGROUND

[0002] Current market mainstream traditional Ω type blade thorn grating net (such as Figure 3 ) generally adopts trapezoidal, triangular or other similar shape Ω type blade thorn with longitudinal and transverse intersection fixed forming (for easy to explain, this article takes trapezoidal and triangular Ω type blade thorn as example, such as Figure 4 C, D in it shows), there are following defects:

[0003] 1. Insufficient structural strength:

[0004] Traditional Ω type blade thorn two sides airfoil due to blanking gap causes material continuity to break (C is trapezoidal gap in Figure 4 , D is triangular gap indication), gap area section area reduces, shear stress concentrates in weak position, easily be damaged by hydraulic shear tool.Compared with continuous airfoil design, the shear resistance of traditional gap structure is significantly reduced.

[0005] 2. Expensive mold cost:

[0006] Traditional Ω type blade thorn grid fixed region is according to the size requirement of industry to grating net hole, the reserved area after blade thorn of two sides airfoil is punched (such as Figure 3 , Figure 4 Show), its longitudinal and transverse intersection constitutes the limited size adjustment of net hole, therefore single specification size Ω type blade thorn cannot constitute the grating net of different security level net hole density adaptation. Need to customize multiple sets of mold to process Ω type blade thorn, leading to low mold reuse rate, and the production cost increases substantially.

[0007] 3. Poor topographic adaptability:

[0008] Traditional Ω type blade thorn airfoil grid fixed area is dispersedly distributed according to periodic law and limited area (such as C, D in Figure 4 Show), further limit the flexibility of fixed point adjustment when blade thorn intersects longitudinally and transversely, cannot constitute Ω type blade thorn grating net of different topographic gradient (such as flat ground, slope) adaptation.

[0009] (Note: Figure 3 , Figure 4 It is prior art schematic diagram according to market open product, not the component part of this patent). SUMMARY

[0010] The application is a kind of Ω type continuous wing surface multi-angle convex spike grid net, which is formed by fixing a plurality of Ω type continuous wing surface multi-angle convex spike belts (1) longitudinally and transversely, and constitutes an overall protection structure with a frame (the specific design of the frame is not within the protection scope of the patent).

[0011] 1. The technical problem solved

[0012] The application eliminates the material discontinuity of the wing surface caused by blanking notches, and improves the overall structural strength and shear resistance.

[0013] The grid fixed area of the application is continuous, which facilitates the free layout of the intersection points, adapts to multiple slope terrains, and reduces the need for mold customization.

[0014] The grid hole size and internal angle of the application are flexible and adjustable, which can meet the protection needs of different terrains and different security levels.

[0015] 2. Technical scheme

[0016] The core structure of the application is an Ω type continuous wing surface multi-angle convex spike belt (1) (as shown in Figure 2 ), which is composed of a hollow tube type channel (11) and two continuous wings (12) on both sides. The thickness of the wing (12) is 0.4mm-3mm, and galvanized steel or aluminum alloy material is preferably used to improve the structural strength and corrosion resistance. The wing (12) is cut and folded to form a multi-angle convex spike (121), and the folding angle is 60°-180°. The shape of the multi-angle convex spike (121) can be flexibly adjusted by cutting and folding process, such as triangle, trapezoid, pentagon, hexagon, sector, zigzag, etc. Different shapes are adapted to the visual deterrent and local piercing needs of different security scenes. The area reserved after the wing (12) is cut and folded to form a multi-angle convex spike (121) is a grid fixed area, which supports the Ω type continuous wing surface multi-angle convex spike belt (1) to be fixed longitudinally and transversely at any position to form a parallelogram grid hole.

[0017] The grid fixed area of the application is continuous, and the intersection fixed points (122) (as shown in Figure 1 ) of the Ω type continuous wing surface multi-angle convex spike belt (1) after longitudinal and transverse intersection can be freely laid out in any area reserved after the wing (12) is removed from the multi-angle convex spike (121) by welding, riveting or buckle points. Those skilled in the art should understand that any equivalent design based on the continuous wing surface cutting and folding process to form a multi-angle convex spike, and to realize the terrain adaptation by adjusting the layout of the intersection points (such as different cutting angles, folding sequences or fixed point densities), falls within the protection scope of the application.

[0018] The grid mesh of the present application is adjustable, the grid mesh shape is parallelogram, the edge length net size is 30mm-300mm horizontally and 30mm-300mm vertically, the horizontal and vertical center distance can be adjusted independently, and the protection requirements of different industry security levels are adapted; the inner angle of the grid mesh is 45°~135°, the mesh is rectangular (inner angle 90°) when installed horizontally, and the mesh is parallelogram (inner angle 45°-135°) when installed on a slope, and the angle and spacing of the longitudinal and transverse fixed points are adjusted to adapt to different slope terrains.

[0019] 3. Beneficial effects

[0020] Significant improvement of shear resistance: continuous wing surface design avoids stress concentration, combined with 0.4mm-3mm wing surface thickness and the selection of galvanized steel / aluminum alloy material, the shear resistance is significantly enhanced compared with traditional notched wing surface structure;

[0021] Enhanced mold versatility: a single mold can adapt to various angle spikes and mesh sizes by adjusting the cutting parameters;

[0022] Optimized terrain adaptability: free layout of cross fixed points supports horizontal, slope (5°-45°) and other scenarios;

[0023] Flexible security level adaptation: the grid mesh size adjustment range is wide (30mm-300mm horizontally and 30mm-300mm vertically), which meets the needs from high-risk areas to ordinary industrial parks. BRIEF DESCRIPTION OF DRAWINGS
