Abstract
The invention discloses a pre-twisted navigational warning ball, which comprises a navigational warning ball body 1 with impressive color and a spiral pre-twisted wire clamp 2, wherein the pre-twisted wire clamp 2 is used for fixing the navigational warning ball body 1 to a wire. The pre-twisted navigational warning ball has good impact resistance and strong environmental tolerance and color retention. The mounting mode of the pre-twisted wire clamp is easy, convenient and quick; the grasping force of the pre-twisted wire clamp to the wire is uniformly distributed on the entire mounting length, and the pressure which is supposed to be borne at a fixed point is uniformly dispersed to the two sides; the rigidity of the wire at the fixed point is enhanced, the stress concentration on the part is reduced, and the fatigue damage of the wire is effectively avoided.
Description
Technical field
The present invention relates to the transmission line marking field, particularly relate in power overhead network the sign series products that aviation aircraft and river, the marine boats and ships that travel are served as warning.
Background technology
Development along with China's aircraft industry, all kinds of number of vehicles are more and more, frequency of utilization is more come height, the low-to-medium altitude field faces the inexorable trend of opening gradually, and a large amount of electric power transmission lines is in the low latitude dense distribution, the cable that has is striden river, aerial wire laying over strait, as does not have suitable sign to remind the position at aircraft pilot and deck officer's power circuit place, residing height, has a strong impact on aircraft and safety of ship and normal electricity supply.
Preformed alert boat ball can as safe as a housely be installed at overhead transmission line easily, evenly disperses the stress of alert boat ball fixed point cable to concentrate, and effectively avoids the fatigue damage of lead.Its color can keep bright-coloured for a long time, caution in time is provided for aircraft pilot and deck officer.
Summary of the invention
The invention provides a kind of preformed alert boat ball, conventional alert boat ball is installed difficulty in the high-altitude, fixed point cable stress is concentrated, problems such as cable fatiguability damage in order to solve.
For reaching above-mentioned purpose, the invention provides a kind of preformed alert boat ball, formed by alert boat ball and helical form preformed armor rods wire clamp two parts.
Further alert boat ball is thin-walled ABS material, and spheroid is that two hemisphere are assembled into, and the spheroid wall thickness is between the 2-5 millimeter, and the surface is bright-coloured orange, redness or white.
Further, the ABS material has added weather-proof and the antiultraviolet composition.
Further, an end is fixed in alert boat spheroid after the bending of every spiral helicine preformed armor rods wire clamp, and an end is wound in outside the cable.
Further, the inner diameter d of preformed armor rods wire clamp is 0.80～0.90 times of wire diameter D.
Further, every preformed armor rods wire clamp is made up of some one metal wires, and every one metal wire all is prefabricated into helical form lines consistent in shape and size.
Further, wire adopts aluminum-alloy wire or zinc-coated wire.
Beneficial effect of the present invention is as follows:
Preformed alert boat ball can be safely, install at overhead transmission line quickly and easily, evenly disperses the stress of alert boat ball fixed point cable to concentrate, and effectively avoids the fatigue damage of lead.Its color can keep bright-coloured for a long time, caution is provided for low flyer driver and deck officer.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, does not limit the present invention.
The line identification series products that the embodiment of the invention relates to preformed alert boat ball can be safely, install at overhead transmission line quickly and easily.
Alert boat spheroid is combined by the hemisphere 1 of two semicirculars in shape as shown in Figure 1.Spheroid is thin-walled ABS material, and thickness is between 2～5mm, and color is bright-coloured orange, redness or white.
Preformed armor rods wire clamp 2 as shown in Figure 2 plays that alert boat ball is fixed to effect on the lead.
During installation, the end with the preformed armor rods wire clamp is fixed on the hemisphere earlier as shown in Figure 3, and the other end is wound on the lead, and both sides are totally two cover preformed armor rods wire clamp actings in conjunction, fixing alert boat ball.Then another hemisphere and the hemisphere of having installed are connected and fixed, finish the installation of whole alert boat ball.The preformed alert boat ball that installs as shown in Figure 4.
Preformed alert boat ball can be installed at overhead transmission line on safe ready ground, effectively avoids the fatigue damage of lead.Its color can keep bright-coloured for a long time, caution is provided for aircraft pilot and deck officer.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
