Abstract

The utility model relates to a warning protective sleeve for overhead cable lines to penetrate a transformer, a wire car and a highway, which is a protective device for telephone cables and optic cables. The warning protective sleeve comprises a plastic circular pipe 2, wherein, the upper part of the circular pipe is provided with a circular slot 1 which protrudes from inside to outside; a slit 3 is lengthways arranged on the side wall of the circular pipe; one side of the slit is provided with a groove 5, wherein, the section of which is circular; the other side is provided with a circular convex edge 4 which is matched with the groove. A steel strand wire and a cable are inserted into the circular pipe through the slit on the wall of the circular pipe, and then the circular convex edge of one side of the slit is inserted into the groove of the other side; thus, the utility model can play favorable protective action on the cable.

Description

Aerial cable line passes through transformer, contact line, strides the caution protective sleeve of highway

The utility model relates to the protective device of a kind of telephone cable, lightguide cable link, and a kind of aerial cable line passes through transformer, contact line, strides the caution protective sleeve of highway.

Built on stilts telephone cable, optical cable are when passing through electric device such as transformer, contact line and crossing highway; requirement wraps up at cable and guiding principle twisted wire external application one protective sleeve thereof; in case issuable electric spark is splashed on the cable, or coats color red and white, make the usefulness of caution.No dedicated devices often adopts bamboo chip to wrap up at present.

The purpose of this utility model is to propose a kind of caution protective sleeve that aerial cable line passes through transformer, trolley line, strides highway that is exclusively used in.

The caution protective sleeve that this aerial cable line passes through transformer, contact line, stride highway comprises the pipe of plastics; one circular groove that protrudes is from inside to outside arranged at the top of pipe; a seam is vertically arranged on the sidewall of pipe; have a cross section to be circular groove on the limit of seam, another side has a circular chimb that matches with above-mentioned groove.

When the caution protective sleeve that this aerial cable line passes through transformer, contact line, stride highway uses; can earlier overhead steel strand be embedded in the pipe through the seam on the pipe wall; and steel strand wire are entered in the circular groove on pipe top; again the seam of cable through pipe embedded in the pipe; then; the circular chimb on the one side of stitching on the pipe is embedded in the groove of another side, and protective sleeve plays a very good protection in just steel strand wire and cable being wrapped in together.This protective sleeve is not yielding when variations in temperature, and installing is convenient.Protective sleeve is outer can also coat color red and white, is installed on the cable of striding highway, river, street, makes warning mark.

Accompanying drawing 1 passes through transformer, contact line for this aerial cable line, strides the structure chart of the caution protective sleeve of highway;

Accompanying drawing 2 passes through transformer, contact line, strides the sectional view of the caution protective sleeve of highway for aerial cable line;

The schematic diagram that accompanying drawing 3 is worked in coordination for the both sides of seam;

Accompanying drawing 4 is the structure chart of geometrical clamp;

The schematic diagram that accompanying drawing 5 matches with protective sleeve for geometrical clamp.

As depicted in figs. 1 and 2; the caution protective sleeve that this aerial cable line passes through transformer, contact line, stride highway comprises the pipe 2 of plastics; a seam 3 is vertically arranged on the sidewall of pipe; have a cross section to be circular groove 5 on the limit of seam, another side has a circular chimb 4 that matches with above-mentioned groove 5.One circular groove 1 that protrudes is from inside to outside arranged at the top of pipe.

As shown in Figure 2, this aerial cable line passes through transformer, contact line, the circular groove 1 of caution protective sleeve of striding highway is slightly narrower than the internal diameter of circular groove 1 with the width that is communicated with place 6 of pipe.Steel strand wire can not deviate from after embedding in the above-mentioned circular groove automatically, install more firm.

As shown in Figure 3; the cross section of circular chimb 4 that this aerial cable line passes through transformer, contact line, stride one side of the seam 3 on the caution protective sleeve of highway can be the glans penis shape; be that its front portion has two inclined-planes 7, the bottom in the cross section of the groove 5 of the another side of seam becomes a wedge angle 8.Such structure, chimb 4 is easy to insert in the groove 5, and is difficult for pulling out from groove, and installing is got up more convenient, firm.

As shown in Figure 4 and Figure 5, the caution protective sleeve that this aerial cable line passes through transformer, contact line, stride highway can also comprise a geometrical clamp 9, and a jaw 10 that matches with circular groove 1 outer wall on protective sleeve top is arranged at the bottom of this geometrical clamp.Geometrical clamp is clipped in the two ends of protective sleeve, protective sleeve and steel strand wire 11 are firmly fixed.When a segment protect cover falls short of, when needing two sections to join, also can two segment protect covers be clamped and connect with a geometrical clamp.
