Abstract

PURPOSE:To offer an electric wire protection pipe for a measure to counter bird nuisance accomplishing both an electric wire insulating protection pipe and bird flying prevention. CONSTITUTION:A crack is provided lengthwise of the lower part of a pipe body 1 formed of an insulating material such as synthetic resin, etc., to provide vertical leg pieces 3 and 3 opposed to each other from both end edges of the crack 2 and, at the same time, interlocking sections 4 and 5 fitted to the insides of the vertical leg pieces 3 and 3 in a detachable manner are provided, and an electric wire protection pipe for a measure to counter bird nuisance is so constituted that a plurality of projecting threads 6 are arranged lengthwise of the surface of the pipe body 1 radially.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire protection tube for bird damage control, which has both the insulation protection of a wire and the function of preventing a bird from stopping on the wire.

[0002]

2. Description of the Related Art Conventionally, a tubular electric wire insulation protective cover has been used to protect electric wires from contact and damage around construction sites or near standing trees such as street trees during construction work. Is known.

In order to prevent birds from flying and stopping at the arm tips of electric poles and causing an electric shock to induce an accident, a single bird having a shape in which a large number of rods are radially forested is used. It is also known to use a device to prevent the flight of the.

[0004]

However, there has hitherto been no apparatus having both functions of electric wire insulation protection and bird flying prevention. Then, the subject of this invention is providing the electric wire protection tube for bird damage countermeasures which achieves both these electric wire insulation protection and a bird flying prevention.

[0005]

In order to achieve the above object, the present invention provides a slit in the lower longitudinal direction of a tubular body made of an insulating material such as a synthetic resin, and the both end edges of the slit. Further, the vertical leg pieces are provided oppositely to each other, an engaging portion that is engaged with the inner side surfaces of these vertical leg pieces to be engageably and disengaged is provided, and a plurality of ridges are radially arranged in the longitudinal direction of the surface of the tubular body. Configured.

[0006]

[Operation] To attach to the electric wire, the vertical leg pieces are opened, the slits are widened to insert the electric wire, and then the vertical leg pieces are narrowed to each other so that the engaging portions are fitted to each other. The ridges are located on the radiating line, and these ridges prevent birds from stopping on their legs.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 is a long tube made of an insulating material such as polyethylene resin. A slit 2 is provided in the lower longitudinal direction, and vertical leg pieces 3 and 3 are provided from both ends of the slit 2. To do. The vertical leg pieces 3 and 3 are formed with a fitting projection 4 on one of the inner surfaces facing each other and a groove 5 on the other side for engaging the fitting projection 4 in a disengageable manner.

Further, a plurality of ridges 6 each having a narrow width toward the tip in the longitudinal direction of the surface of the tubular body 1 are radially projected at a predetermined opening angle (40 degrees in FIG. 2). And adjoin. An interval is set so that birds cannot stop when straddling the ridge 6. The electric wire protection tube for bird damage countermeasures of the present invention configured as described above can be manufactured with high productivity by extrusion molding or the like.

In the bird damage prevention electric wire protection tube, the vertical leg pieces 3 and 3 are opened, the slits 2 are widened, and the electric wire W is inserted and attached, and the vertical leg pieces 3 and 3 are closed. By engaging the fitting projections 4 with the recessed grooves 5, a plurality of projections 6 are projected radially on the surface of the tubular body 1 as shown in FIG.
It is impossible for the bird to stop by straddling these ridges 6 with legs, and it is possible to perform the two functions of protecting the electric wire W and protecting the bird from flying at the same time.

Further, in the structure shown in FIGS. 4 and 5, a protrusion 6 is provided on the upper surface facing the slit 2, and a predetermined opening angle (shown in FIG. 5) is formed with respect to the protrusion 6. 30 for each
This is an example in which the ridges 7 and 7'are provided at a certain angle. In addition,
In this embodiment, the height of the ridge 6 is increased and the heights of the ridges 7 and 7'are both lower than the height of the ridge 6, so that the bird does not stop when straddling the tips of the ridges 6 and 7 and 6 and 7 '. It is set not to get.

[0011]

As described above, the electric wire protection tube for bird damage prevention according to the present invention has both functions of electric wire insulation protection and bird flight prevention, and is easy to mount. Moreover, it can be produced with high productivity by extrusion molding of polyethylene resin or the like, which is economically advantageous.
