Description
Technical field
The utility model relates to the protective device of communication cable, optical cable and catv line, is specifically related to a kind of warning protective sleeve structure of share when utilizing steel strand wire to make somebody a mere figurehead communication cable, optical cable and catv line.The following general designation of cable, optical cable and catv line " cable ".
Background technology
Communication cable, optical cable and catv line are not being imbedded when underground, need cross over traffic main artery, critical facility and pass through electric devices such as transformer, contact line by built on stilts form.Built on stilts cable need set up the steel strand wire of a tensioning usually, and utilizes cable clip that cable is suspended on the steel strand wire.In order to protect cable not to be subjected to power line and other damage of external force, key aspect requires to be provided with protective sleeve structure and alert flag outside cable and steel strand wire thereof.Protective sleeve of the prior art is the circular sleeve structure mostly; though some has also coated color to warn in its outside; but angle from the driver; the caution area is big inadequately; therefore in fact still eye-catching inadequately, owing to the space that holds cable is less, original cable clip to be removed during installation in addition; increased the burden of protective sleeve, made the reliability decrease of protective sleeve.Chinese patent has been announced a name August 22 calendar year 2001 and has been called " a kind of cable protecting sleeve ", and the patent No. is 00248713.6, and notification number is the utility model patent of CN2444327Y.This patent discloses a kind of technical scheme with good effect from the angle of anti-high voltage capability, but this technical scheme is seen the defective of breaking away from traditional protective sleeve structure not yet from the angle that the warning surface effect can be provided.
The utility model increases the caution area by the contour structures that changes protective sleeve, further improves the caution effect when protection is provided.
Summary of the invention
For achieving the above object; the technical solution adopted in the utility model is: a kind of aerial cable warning protective sleeve; this protective sleeve main body is at axial sleeve structure; constitute case by symmetrical two side guard plates on cross section, two side guard plates connect mutually at the upper extreme point place, and extend downwards along both sides; case envelope up becomes a steel strand wire chamber; below envelope become a cable chamber, the steel strand wire chamber is communicated with by neck with the cable chamber, the following case in cable chamber is a parallel construction.The innovation and creation of the technical program are: the flat structure of cable chamber for erectting, its corresponding both sides case is provided with mild warning surface towards the ground visual direction, and warning surface is vertically highly more than or equal to 2/3rds of protective sleeve whole height.
The relevant of technique scheme is explained as follows:
1, described " axially ", " cross section ", " top ", " below " and " about " be the orientation of finger guard under in working order, referring to accompanying drawing 1, axial fore-and-aft direction; Cross section is exactly the cross section of accompanying drawing 1 expression.
2, described " flat structure of setting " is meant a kind of shape, in other words is a kind of vertical-horizontal proportion relation, and this programme requires aspect ratio greater than 1, and therefore circle, square etc. foreclose.Its objective is outwards to provide bigger warning surface.
3, the requirement of described " mild warning surface " is from the angular field of view that receives alert flag; because protective sleeve is located at the top, traffic main artery apart from ground certain altitude in the air, has only the protective sleeve both sides to adopt mild warning surface to provide and imitate the caution effect ground.Mild identification is confirmed with above-mentioned aspect ratio.
In the technique scheme, the result that described flat structure comprises following typical structure and draws by variation and combination:
1, flat structure is an ellipsoidal structure;
2, flat structure is the Long Circle structure;
3, the triangular structure of flat structure for standing upside down;
4, flat structure is a rectangle structure;
5, flat structure is trapezoidal etc. for being inverted.
In the technique scheme, better for the fixed effect that makes the steel strand wire chamber, when described steel strand wire chamber was communicated with by neck with the cable chamber, the width of connection place can be less than steel strand wire chamber width.The following parallel construction in above-mentioned cable chamber is a fastening position, on fastening position fixing hole can be set vertically, and adopts bolt nut to be fixed.The mild warning surface of the utility model can be coated with and paste common alert flag, also can be coated with to paste reflecting sign to improve the caution effect.
The utility model operation principle is: increase the caution area by the contour structures that changes protective sleeve, simultaneously for cable provides bigger volume space, cable clip and cable are placed in the cable chamber simultaneously.During use this protective sleeve lower ending opening place is separated gently, from top to bottom steel strand wire, cable and cable clip are wrapped into together, use the fixing hole of special-purpose plastic bolt fastening position then, the nut of screwing on gets final product.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, the novel structure after the improvement flattens the outside, both sides of protective sleeve; area increases; and the outside that makes both sides is bigger, milder; desirable warning surface structure is provided; make protective sleeve playing the safeguard protection effect simultaneously, better bring into play its alarm function, especially after being coated with the subsides reflecting sign on the warning surface; not only be fit to be installed in the intersection of cable and power line, and be fit to be installed in common the mistake on the built on stilts cable in street.
2, the protective sleeve structure after the improvement is after two sides are coated with the subsides reflectorized material, and the night safe alarm function is more obvious, and especially concerning the vehicle that some superelevation are travelled, caution and protection effect are more outstanding.
3, the protective sleeve after the improvement provides bigger volume space for cable; do not need during installation original cable clip is removed; can directly steel strand wire, cable and hook integral body be wrapped in the protective sleeve, so both make things convenient for installation, also make built on stilts cable more solid and reliable simultaneously.
4, the existing good caution effect of this protective sleeve can be born certain high pressure that the power line of accidental damage causes again and be hit, and especially after protective sleeve adopted PVC to prevent that the high pressure material is made, effect was more outstanding.
