DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire protection tube for protecting a transmission / distribution electric wire, which also has a function of preventing bird damage.

[0002]

2. Description of the Related Art Conventionally, when construction is performed close to a transmission and distribution line or when the transmission and distribution line is erected close to a street tree, required transmission and distribution lines have to be protected. A wire protection tube formed by dividing a lower edge along a longitudinal direction of a tube made of a synthetic resin over the length so as to be openable is attached to the pipe body. Some have the function of preventing bird damage so that birds do not stop. For example, as described in Japanese Patent Application Laid-Open No. 7-79682, a number of barrier rods are provided in a row in the vertical and horizontal directions along the longitudinal direction at the upper edge and the left and right edges of the wire protection tube. are doing.

[0003]

However, in the bird's harm prevention electric wire protection tube, each barrier rod is vertically protruded from the upper edge and horizontally protrudes from both sides in the horizontal direction. For example, if the bird protection wire protection tube is turned upside down by strong winds or the like due to strong winds, there is no barrier bar to protrude upward, and the bird protection function cannot be performed. There was. Therefore, the present invention has been made to solve the above problems,
It is an object of the present invention to provide a bird harm prevention electric wire protection tube that can always reliably exhibit a bird harm prevention function even when rotated by strong wind.

[0004]

In order to achieve the above object, a bird's harm prevention electric wire protection tube according to the present invention is constructed such that one side edge along a longitudinal direction of a tube made of synthetic resin is used as a transmission and distribution line. An electric wire protection tube formed by being split openably so as to be adhered, wherein a number of barrier rods are radially formed over the entire outer peripheral surface of the electric wire protection tube so as to keep an interval at which birds cannot stop. It is constructed by protruding. As described above, since a large number of barrier rods are provided so as to protrude over the entire outer peripheral surface of the wire protection tube, for example, when the wire protection tube is covered with a transmission / distribution line and is rotated by receiving a strong wind during use, Regardless of the rotation state, the barrier rod always projects above the electric wire protection tube, thereby reliably preventing birds from approaching.

[0005] Further, if each of the barrier rods is protruded along a trajectory spirally drawn on the outer peripheral surface of the electric wire protection tube, the total number of barrier rods in the electric wire protection tube can be reduced to a minimum. Can be set to

A plurality of rows of small holes 8, 8... Are provided at predetermined intervals along the longitudinal direction thereof while maintaining a 0 ° interval.
Each of the small holes 8, 8... Is for inserting and attaching a barrier rod 9 described later, and the small holes 8, 8,. Have been.

Reference numeral 9 denotes a barrier rod formed of a flexible synthetic resin into a nail shape. As shown in FIG. 4, the barrier rod 9 is formed by a disc at the base end of a long shaft portion 10 having a tapered shape. It is formed integrally with a head 11 of a shape. Further, a plurality of (for example, four) triangular side ribs 12 are protruded from the outer peripheral surface of the shaft portion 10 near the head 11 at equal intervals so that two opposed ribs form a mountain shape.
An interval S is provided at the lower ends of the ribs 12, 12,... Between the ribs 12, 12,. Further, a small ball 13 is provided at the tip of the shaft portion 10, and the shaft portion 1 is attached to a rubber glove worn by a worker during work.
When the tip of 0 hits, the small ball 13 prevents the rubber glove from being perforated. This is to prevent an accidental electric shock caused by a hole in the rubber glove if the hole is formed in the rubber glove.

Then, with the joint B not connected to the wire protection tube A, the projecting pieces 5, 5 of the tube 1 are opened to the left and right, and the heads 11 of the barrier rods 9, 9,. Hole 8,
By pressing the shaft portion 10 into the small hole 8 and pressing it, as shown in FIG.

Are projected radially on the outer peripheral surface of the electric wire protection tube A, and at intervals such that birds cannot be stopped along the longitudinal direction of the tube body 1 as shown in FIG. It will be.

The electric wire protection tube C for bird damage prevention according to the present invention has the above-mentioned structure, and as shown in FIG.
On the other hand, the protruding pieces 5, 5 and 6, 6 of the electric wire protection tube A and the joint B are spread and attached to the left and right, and the electric wire protection tube A and the joint B are sequentially connected to one another over a required length. Use in a connected state. This protects the electric wire W and prevents the birds from approaching by a large number of barrier rods 9, 9,... To prevent. Moreover, since the respective barrier rods 9, 9 ... project radially from each other over the entire outer peripheral surface of the tube 1, even when the bird protection cable C is rotated under strong wind, Since any one of the barrier rods 9, 9,... Always faces upward, it is possible to reliably prevent a bird from approaching.

Wire protection tube C for bird damage prevention shown in FIGS. 6 and 7
Reference numeral 1 relates to another embodiment, in which a plurality of small holes 8, 8... Provided on the outer peripheral surface of an electric wire protection tube A are arranged in a large number along a trajectory G drawn spirally. By inserting and fixing the barrier rods 9, 9 ... in these small holes 6, 6, ..., a number of barrier rods 9, 9 along the trajectory spirally drawn on the outer peripheral surface of the electric wire protection tube A. 9 are projected and arranged radially at an angle of 60 degrees as shown in FIG. In this embodiment, the approach of a bird can be prevented in exactly the same manner as in the present embodiment. In this case, in particular, the number of the barrier rods 9, 9,... Can be set to a necessary minimum.

8 and 9 show a wire protection tube C for bird damage prevention.
Reference numeral 2 also relates to another embodiment, and this does not use a plurality of pieces having a required length in a continuous manner as in this embodiment, but uses only one piece. For this reason, the length is relatively long, and the joint B is unnecessary as in the present embodiment. That is, the bird protection cable protection tube C2 is made of a synthetic resin tube 14 having a required length and diameter. Then, at the lower edge along the longitudinal direction of the pipe body 14, a division 15 is made to be freely expandable, and the division 15
Projecting pieces 16, 16 for introducing the power transmission and distribution line W over the entire length are provided on both left and right sides of the outer edge of the edge. In addition, fitting projections 17 and fitting recesses 18 are provided on inner surfaces of the projecting pieces 16, 16 facing each other.

A plurality of small holes 8 are provided on the outer peripheral surface of the tube 14 along the trajectory G drawn spirally in the same manner as in the bird harm prevention wire protecting tube C1 and are spaced apart by a predetermined interval. , These small holes 8, 8,...
Is inserted and fixed. In this embodiment, the approach of birds can be prevented in exactly the same way as in the present embodiment, and the number of barrier rods 9, 9,... Can be set to the minimum necessary.

[0015]

As described above, the wire protection tube for preventing bird damage according to the present invention has a plurality of barrier rods arranged radially over the entire outer peripheral surface of the wire protection tube so as to keep an interval at which birds cannot stop. Even if the wire protection tube for bird damage prevention rotates due to strong wind during use, one of the barrier rods will always protrude above the tube,
This can surely prevent the bird from approaching. Further, if the plurality of barrier rods are protruded along a trajectory spirally drawn on the outer peripheral surface of the electric wire protection tube, the number of barrier rods can be set to a necessary minimum. Cost reduction can be achieved.
