Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a device that is attached to a bracket or the like that supports a feeder line for overhead contact lines to prevent bird damage.

[Prior Art] Conventionally, as shown in the first diagram, the feeder line of the overhead contact line is
An upper long-stem insulator g1 and a lower long-stem insulator g are attached to the pillar p.
It is suspended and supported by movable brackets b1 and b2 attached via 2, but an earth conductor e is attached to this long insulator, and the movable brackets b1 and b2 on the feeder line f side and the earth conductor Since there is a potential difference between the insulator and the insulator, if a crow or other bird lands on this insulator, a flashover accident will occur, and such accidents are extremely common, especially in the crow's habitat where there are many forests and forests. , the repair work required a large number of people and a large amount of money. For this reason, various obstacles have been installed to prevent the birds from stopping, but the installation work is time-consuming.

[Problems to be Solved by the Invention] The present invention provides a device for preventing bird damage to feeder lines that can be easily installed and reliably prevents birds from perching on the movable bracket.

[Structure of the Invention] [Means for Solving the Problems] The present invention enables the insulator to be easily mounted on the movable bracket by means of two curved U-shaped mounting pieces for mounting the insulator arranged above and below. The vertical rod is erected on a movable bracket using a mounting piece to prevent birds from perching on it.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a front view of the device according to the present invention installed, FIG. 2 shows a side view of the device, FIG. 3 shows a top view of the device, and FIG. 4 shows another embodiment.

In FIGS. 2 and 3, reference numeral 1 denotes an elongated vertical rod made of an insulating material such as plastic, and a flange-like hook 2 is provided in the middle of the rod. This hook part 2 is
It is made integral with the vertical rod 1, or is provided as a rubber annular body that is fitted into the center of the vertical rod 1.

Reference numerals 3 and 4 are curved U-shaped mounting pieces for attaching the insulator, 3 is an upper mounting piece, and 4 is a lower mounting piece. Each mounting piece 3, 4 is formed into a curved U-shape using an insulating material such as plastic.
A vertical rod insertion hole 7 is provided in each of the lower pieces 6 and 6.

The insulator mounting curved U-shaped mounting pieces 3, 4 and the vertical rod 1 constructed as described above are attached to the long insulators g1, g2 supporting the movable bracket shown in the first figure. The upper long-stem insulator g1 is sandwiched between the curved U-shaped mounting pieces 3 disposed above, and the lower long-stem insulator g2 is sandwiched between the curved U-shaped mounting pieces 4 disposed below, and the vertical rods of each mounting piece 3 and 4 are inserted. The vertical rod 1 is inserted through the hole 7, and the hanging portion 2 of the vertical rod is placed on the upper piece 5 of the upper curved U-shaped mounting piece 3. As a result, each mounting piece 3,
4 is fixed with a long trunk insulator sandwiched between the curved U-shaped portion and the vertical rod. Each of the above-mentioned mounting pieces is to be attached to the insulator part between the tip of the long insulator to which the movable bracket is attached and the ground wire e, and each mounting piece can be fixed more firmly with a binding wire as necessary. It's okay.

FIG. 4 shows a modification of the vertical rod 1.
A branch rod 11 is provided above the hooking part 2 of 0 and is made to branch out, and this vertical rod 10 is also attached to the long trunk insulator by the curved U-shaped mounting pieces 3 and 4 for attaching the insulator, as described above. be.

[Effects of the invention] As described above, in the present invention, the vertical rods are attached to the long insulators, and the vertical rods are erected between the brackets b1 and b2 and the ground conductor e, so that the long insulators are free from birds. This prevents the bird from stopping, and even if the bird lands on the tip of the insulator, the vertical rod is between the bracket and the ground conductor, so there is no chance of a flash trip. In addition, to install the vertical rod, all you need to do is to sandwich the insulator between the curved U-shaped mounting pieces and insert the vertical rod into the vertical rod insertion hole, so the work can be done extremely easily and quickly. The U-shaped mounting piece uses the upper mounting piece 3 and the lower mounting piece 4, and these are attached to the upper and lower long insulators g1 and g2, so the vertical rod can be stably attached, and the installation The pieces are fixed between the folds of the insulator and are stable and do not move.
