Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective pipe for covering and protecting an electric wire installed near a road tree or the like when various works are carried out near the transmission and distribution electric wires. , It also has the function of preventing bird damage.

[0002]

2. Description of the Related Art Conventionally, in order to protect a power transmission / distribution line that is in contact with a roadside tree or when construction is performed near the power transmission / distribution line, it is necessary to coat a wire protection tube over a required length. Has been done. In addition, a bird damage prevention tool, which is separately formed, is attached to the electric wire protection tube used in this manner to prevent bird damage.

[0003]

As described above, in the conventional electric wire protection tube, it is necessary to re-install a bird damage preventive device separately formed in order to prevent bird damage, and therefore, so to speak, a double labor is required. In addition, the bird damage prevention device attached to the electric wire protection tube may be misaligned during use, and the function of preventing bird damage may not be sufficiently fulfilled. Therefore, an object of the present invention is to provide an electric wire protection tube for bird damage prevention that solves such problems.

[0004]

In order to achieve the above object, the bird damage preventing electric wire protection tube of the present invention has a fitting brim portion for connecting a joint to an end of a tube body made of synthetic resin. The pipe body is divided at one side edge in the longitudinal direction, and projecting pieces for introducing electric wires are installed oppositely on both sides of the divided end edge so as to be openable and closable, and the joint of the pipe body is further fitted. A large number of small holes are bored at equal intervals on the entire surface leaving the surface, while a synthetic resin having flexibility is provided with a disk-shaped head integrally with the base end of the tapered shaft and the shaft is Forming a bar-shaped bar with a rib in the shape of a mountain around the disk-shaped head, and inserting the shaft part of the bar from the inside of the tube into the small hole to press it, Between the lower ends of the ribs of the barrier rod that have passed through the holes and the disk-shaped head of the barrier rod, the wall thickness of the pipe is The shaft portion of the barrier rod and so as to be erected held on the surface of the tube by lifting.

[0005]

The wire protection tube for bird damage prevention of the present invention is mounted on the electric wire by inserting the electric wires by opening the projecting pieces outwardly so that the shaft portions of the barrier rod body are equidistantly arranged on the pipe body. Prevents birds from approaching around the electric wire protection tube by protruding.
Moreover, such a function of preventing birds from approaching is achieved at once by attaching the wire protection tube to the wire,
The number of mounting steps is small, and the position of the barrier rod does not shift or come off.

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 denotes a synthetic resin tube body having a required length and diameter, and a fitting flange portion 3 having a gooseneck-shaped engaging projection 2 for securely joining to a joint is provided at one end in the longitudinal direction. ing. Further, the tubular body 1 is divided into 4 at one side edge in the longitudinal direction, and the fitting flange 3 is provided on both outer sides of the edge of the division 4.
The projecting pieces 5 and 5 for introducing the electric wire are installed to be openable and closable to the left and right over the entire length except for. Then, a large number of small holes 6 are formed at equal intervals on the circumferential surface of the tubular body 1 at the positions where the projecting pieces 5 and 5 face each other and at both left and right side positions to form a wire protection tube A.

Reference numeral B denotes a joint fixed to the other end of the tubular body 1 for connecting the adjacent electric wire protection tubes A. The joint B has an inner diameter substantially the same as the outer diameter of the electric wire protection tube A. Similarly to A, the projecting pieces 7, 7 for dividing the lengthwise direction and introducing the electric wires on both outsides of the divided edges are provided so as to be openable and closable.
As shown in FIG. 5, a fitting holding portion 8 to which the fitting flange portion 3 provided at one end of the adjacent electric wire protection tube A is fitted is formed inside the substantially middle position.

On the other hand, 9 is a barrier rod formed by a synthetic resin having flexibility in the shape of a nail. The barrier rod 9 has a disk-shaped head 11 at the base end of a long shaft 10 having a tapered shape.
Are formed integrally with each other, and a plurality of ribs 12 each having a triangular side surface are provided at equal intervals (four in the embodiment) on the peripheral surface of the shaft 10 near the disk-shaped head 11, and two ribs facing each other are provided. I am trying to form a mountain shape. At the lower ends of these ribs 12, a space S is provided between the ribs 12 and the head 11 so that the wall thickness of the tubular body 1 can be accommodated.

Then, the shaft portion 10 of the barrier rod body 9 is inserted into the small hole 6 of the pipe body 1 from the gap between the protruding pieces 5 and 5 of the pipe body 1 opened to the left and right, and the barrier rod body 9 is pressed.
The ribs 12 of the barrier rod 9 are passed through the small holes 6, and the wall thickness of the tube 1 is sandwiched between the ribs 12 of the barrier rod 9 and the head 11 as shown in FIG. Is fixed to the tubular body 1, and the shaft portion 10 of each barrier rod body 9 is projected so as to stand on the surface of the tubular body 1 as shown in FIG. Although the small holes 6 are provided so as to form three rows in the longitudinal direction of the tubular body 1 in the embodiment, it is desirable that the small holes 6 are provided without being restricted by this embodiment. When the diameter is large, it is preferable to provide the particles at regular intervals in a random direction.

With respect to the electric wire W erected on the electric pole by the electric wire protection tube for bird damage prevention of the present invention thus constructed, the protruding pieces 5, 5 and 7, 7 of the electric wire protection tube A and the joint B are arranged on the left and right sides. Spread and adhere, and connect a plurality of electric wire protection tubes A one by one by fitting the fitting flange portions 3 at one end to the joints B of the other electric wire protection tubes A to form one wire over the required length. By using it in a connected state, it is possible to protect the electric wire W and prevent birds from approaching each shaft portion 10 of the barrier rod body 9 that stands on the surface of the tube body 1.

[0011]

As described above, the bird damage preventing electric wire protection tube of the present invention protects the electric wire with the electric wire protection tube and the joint by one operation of adhering the electric wire to the electric wire, and at the same time, protects the electric wire from a large number of trees. The barrier rod prevents the birds from approaching and prevents the occurrence of bird damage on the electric wire, thus eliminating the need for mounting. Since the barrier rod is securely fixed to the pipe by the disk-shaped head and the rib, the barrier rod is never displaced or separated from the pipe.
