Description

[Detailed Description of the Invention] This invention relates to a power line marker that prevents birds, especially protected and migratory birds such as swans and cranes, from colliding with power distribution lines.

As is well known, several protected birds are reported to come into contact with power lines and get injured, collide and fall, or die from electrocution every year.

The cause of this accident is believed to be that power lines become difficult to identify when the aircraft flies into a cloudy sky or into the setting sun.

In addition, if protected birds are often injured or killed by power distribution lines, there are concerns that the protected birds will feel unsafe and will not fly to the area.Also, the power lines themselves may be damaged due to collisions with birds, so it is important to take measures to prevent this. It was.

Therefore, this idea is to hang triangular flags in colors that birds can identify from power distribution lines, so that birds flying near the power lines can easily locate the power distribution lines.

Next, the structure of the proposed electric wire marker will be explained with reference to the drawings of the embodiment. 1 is a yellow rope stretched from utility pole P to P'; rope 1 is stretched between utility poles P and P' somewhat longer than the utility pole installation interval H; A rope 1 stretched between utility poles P and P' is bent similarly to a power distribution line W.

2 is a triangular flag made of red fabric that is hung from a rope 1. The rope 1 is inserted through the base 2a of the triangular flag 2 and hung at appropriate intervals.For example, if the width of the triangular base 2a is 40 cm, , the length from the base 2a to the tip 2bt is 50
CfIt's triangular flag 2 is hung at intervals of 70 Crn with the tip 2b facing downward.

Reference numeral 5 denotes a hanger for suspending the rope 1 from the power distribution line W, and the hanger 5 has a locking portion 6a that engages with the tips of semicircular pieces 6A t 6B that can be opened and closed left and right.

6b, and a locking portion 6a provided on both semicircular pieces 6A, 6B.
, 6b form an annular part 6 for inserting the power distribution line W, and is made of an elastic insulating material and is inserted into various places on the rope 1.

Since the proposed electric wire marker has the structure as described above, when it is to be strung near the distribution line W connected to the utility poles P and P', the triangular flag 2 and the hanger 5 should be properly inserted into the rope 1 in advance. Keep it
First, the semicircular pieces 6A and 6B forming the annular part 6 of the hanger 5 fixed at various places on the rope 1 are separated from each other to the left and right, and the semicircular pieces 6A are separated from each other.

After inserting the distribution line W between 6B, the semicircular pieces 6A and 6B are joined and closed so as to wrap around the distribution line W, and the locking part 6a of the closed semicircular piece 6A and the locking part of the semicircular piece 6B are 6b are engaged with each other to form an annular portion 6, and by sequentially inserting the hanger 5 into the distribution line W, the distribution line W is inserted into the annular portion 6 formed by the semicircular pieces 6A and 6B of the hanger 5. Therefore, the rope 1 is suspended from various parts of the power distribution line W by the hanger 5.

After suspending the rope 1 from the distribution line W while forming the annular part 6 with the semicircular pieces 6A and 6B of the hanger 5 in the above manner, one end of the rope 1 is wrapped around the utility pole P and the other end is wrapped around the utility pole P'. Fix it and complete the installation of the proposed electric wire marking device.

When stretching rope 1 between utility poles P and P', use semicircular piece 6A16B
Since the annular portion 6 of the hanger 5 formed by the closing lock is larger than the diameter of the distribution line W, the hanger 5 slides on the distribution line W according to the tension of the rope 1, and when the tension is completed, the distribution line W On top! They are scattered at equal intervals to prevent the rope 1 from being excessively bent.

Note that the specific implementation of the invention is not limited to the above embodiment, and it is desirable that the rope 1 and the triangular flag 2 be made of an insulating material. The means for attaching the hanger 5 to the distribution line and the means for attaching the hanger 5 to the distribution line can be changed as appropriate as long as they do not go against the gist of this invention.

Therefore, if the proposed power line marker is strung between utility poles in areas where protected birds and other birds fly, the red triangular flags suspended from ropes will sway in the wind, making it easy for birds to discover the location of power lines. This allows you to fly while avoiding contact with or collision with power lines.

Moreover, the ropes strung between the utility poles have hangers attached to them at various places outside of the triangular flags, and the distribution line is inserted into the annular part formed by the semicircular pieces of the hangers.
The deflection of the rope can be significantly reduced at smaller intervals than when the rope is directly stretched, and since the deflection of the rope is small, the triangular flag will not become entangled with the power distribution line due to the deflection of the rope.

In addition, the proposed tag can not only be easily erected without the use of tools, but can also be easily removed once the protected bird period has passed, and the tag is made of insulating material. Therefore, in addition to the above-mentioned features that protect protected birds from accidents caused by power distribution lines, such as preventing electric shocks even if birds or humans touch the tag, the proposed tag also protects birds from damaging power distribution lines. This has a significant practical effect in protecting power distribution lines.
