Embodiment Construction

[0020] Such as Figures 1 to 5 As shown, a height-limiting signboard for 10KV overhead lines includes a substrate 1, a light-absorbing layer 2 covering the surface of the substrate 1, a light-reflecting portion arranged on the surface of the light-absorbing layer 2, and a protective layer 4 covering the light-absorbing layer 2 and the light-reflecting portion , the reflective part includes a reflective frame 31 and a reflective block 32 in the shape of a font or a figure or a combination of a font and a figure enclosed in the reflective frame 31. The protective layer 4 is a transparent protective layer, and the top edge of the substrate 1 is arranged There is a first hooking part 5 for hanging on a 10KV overhead line, and the base plate 1, the light-absorbing layer 2, the light-reflecting part, the protective layer 4 and the hooking part 5 are all insulators. A number of glass beads 33 with a particle diameter between 5-12 μm are embedded on the surface of the reflective part....

Abstract

The invention provides a height limiting signboard for 10KV overhead lines. The signboard comprises a base plate, a light absorbing layer which covers the surface of the base plate, a light reflecting part which is arranged on the surface of the light absorbing layer, and a protecting layer which covers the light absorbing layer and the light reflecting part, wherein the light reflecting part comprises an outer light reflecting frame, and a light reflecting block which is surrounded by the outer light reflecting frame and is of a font shape, or a graph shape, or a combined shape of the font and the graph; the protecting layer is a transparent protecting layer; first hooking parts which are used for hooking on the 10KV overhead lines are arranged at the edge of the top of the base plate; the base plate, the light absorbing layer, the light reflecting part, the protecting layer and the hooking parts are respectively insulators. The signboard can play the role of prompt, the caution for supply lines is realized, accidents that guide lines are touched by vehicles, ships and the like are reduced, and line breaking and rod breaking of the overhead lines are reduced.

Description

technical field [0001] The invention relates to a height-limiting signboard for 10KV overhead lines. Background technique [0002] When 10kV power distribution lines cross roads and rivers, the height limit signs are not installed at the crossing points, resulting in frequent accidents of super-high vehicles and ships touching the wires and breaking the wires and poles. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a height-limiting signboard for 10KV overhead lines, which can serve as a reminder, realize warning reminders for power supply lines, reduce the occurrence of accidents where vehicles, ships, etc. touch wires, and reduce overhead line breaks, A broken rod accident occurred. [0004] In order to solve the above-mentioned existing technical problems, the present invention adopts the following scheme: a height-limiting signboard for 10KV overhead lines, including a substrate, a light-absorbing layer co...
