Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bird damage prevention tool for a transmission line tower for preventing birds from entering the transmission line tower.
[0002]
[Prior art]
Birds such as crows fly on the transmission line tower, and it is easy to make a nest inside it. The materials that birds bring in to nest include materials that have electrical conductivity, such as barbs, which may cause short-circuit accidents. In addition to this, various damages such as drunkenness occur when birds fly to the transmission line tower.
[0003]
[Problems to be solved by the invention]
For this reason, various countermeasures have been proposed in the past for preventing bird damage to power transmission towers, but none of them have a sufficient prevention effect.
[0004]
Then, an object of this invention is to provide the bird damage prevention tool of the power transmission line tower which can prevent effectively a bird flying in a power transmission line tower.
[0005]
[Means for Solving the Problems]
The bird damage prevention device for a power transmission line tower according to the present invention has two long members attached to an angle member , which is a horizontal member of the power transmission line tower, and a lattice shape with a pitch between the two long members. It is composed of a plurality of string-like bodies that are stretched, and screw portions are provided at both ends of the U-shaped plate that holds the long member, and this screw portion is inserted into one end portion of the connecting plate, and a nut is inserted into this screw portion. The long member is held by the U-shaped plate and the connecting plate, the U-shaped member is brought into contact with the other end of the connecting plate, the U-shaped member is attached to the angle member, By screwing a bolt into the U-shaped member and pressing the tip of the bolt against the surface of the angle member, the U-shaped member is detachably fixed to the angle member, and at least one of the two long members is attached to the horizontal member. The angle member , which is a member , is detachably attached.
[0006]
Desirably, a spring for tensioning the string-like body is provided.
[0007]
According to the bird damage prevention tool for a transmission line tower having the above-described configuration, it is possible to effectively prevent birds from flying into the transmission line tower by using a string-like body stretched in a lattice shape. Further, when the worker climbs onto the transmission line tower and performs the insulator cleaning work, the antirust coating work, or the like, the string-like body interferes with these works. Therefore, in this case, by removing one of the long members from the member, the string-like body can be removed so as not to obstruct the work. It can be performed.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a transmission line tower, FIG. 2 is a perspective view of a bird damage prevention tool for the transmission line tower, and FIG. 3 is a perspective view of a bird damage prevention tool for the transmission line tower with one long member removed. FIG. 4 is a side view showing an attachment structure of a bird damage prevention tool for a transmission line tower.
[0009]
In FIG. 1, a transmission line tower 1 is composed of a main body 2 standing upright on the ground and an arm part 3 projecting sideways from the main body 2, and a insulator 4 is connected to a tip 4 of the arm part 3. Is provided. On the outer surface of the main body 2 (four surfaces when the main body 2 has a quadrangular planar shape), a bird damage prevention tool 10 in which string-like bodies 11 are stretched in a lattice shape is mounted.
[0010]
Next, the bird damage prevention tool 10 will be described. In FIG. 2, the bird damage prevention tool 10 has a plurality of string-like bodies 11 such as ropes and wires stretched in a lattice form at a pitch P on long members 12 and 13 composed of upper and lower two pipes and rods. It is made up. The size of the pitch P is a size that can prevent a bird with its blades spread from entering.
[0011]
A spring 14 is connected to the end of the string-like body 11 to tension it, and one end of the spring 14 and one end of the string-like body 11 are vertically moved via a stopper 15 respectively. Are attached to the long members 12 and 13. Of course, you may provide the spring 14 in the both ends and center part of the string-like body 11. FIG.
[0012]
Reference numeral 6 denotes an angle member which is a horizontal member for constructing the main body 2 of the transmission line tower 1. Next, with reference to FIG. 4, the fixture 20 which mounts the elongate members 12 and 13 to the angle member 6 so that attachment is possible is demonstrated. Reference numeral 21 denotes a U-shaped plate that holds both end portions of the long members 12 and 13, and a screw portion 22 at each end portion is inserted into one end portion of the connecting plate 23. The long members 12 and 13 are held by the U-shaped plate 21 and the connecting plate 23 by screwing the nut 24 onto the screw portion 22. A U-shaped member 25 is brought into contact with the other end of the connecting plate 23, and the connecting plate 23 and the U-shaped member 25 are joined by screwing a bolt 26. U-shaped member 25 is mounted on a horizontal en grayed seal member 6, removable its tip is screwed into the bolt 26 by pressing strongly to the surface of the en grayed seal member 6, U-shaped member 25 in Ann grayed seal member 6 Freely fixed. Elongate members 12, 13 are mounted Ann grayed seal member 6 as described above.
[0013]
As shown in FIG. 1, the bird damage prevention tool 10 is mounted on the outer surface of the main body 2 and prevents the birds from entering the main body 10. In this case, the string-like body 11 is tensioned by the spring force of the spring 14 and maintains a straight lattice state. In FIG. 1, the elongated members 12 and 13 are given subscripts a, b, and c. A string-like body 11 extending upward and downward is attached to each of the intermediate long members 13a, 12b, 13b, and 12c between the uppermost long member 12a and the lowermost long member 13c.
[0014]
There are cases where an operator rises to the main body 2 of the transmission line tower 1 and performs maintenance work (cleaning work of the insulator 4, painting work of the members constructing the transmission line tower 1), etc. 11 interferes with the work. Therefore, in such a case, as shown in FIG. 3, the nut 24 is loosened and one of the long members 13 is removed from the U-shaped plate 21, and the string-like body 11 is retracted to a position where it does not interfere with the above operation and removed. To do. Of course, by removing the U-shaped member 25 from the angle member 6 by loosening the bolt 26, the elongate member 1 and the fitting 20 may be removed from the integrally-en grayed seal member 6. The means of attaching the elongate members 12 and 13 in Ann grayed seal member 6 is not limited to the fixture 20.
[0015]
【The invention's effect】
As described above, according to the present invention, it is possible to effectively prevent birds from flying into the transmission line tower by stretching the string-like body in a lattice pattern. Further, when the worker climbs onto the transmission line tower and performs the insulator cleaning work, the antirust coating work, or the like, the string-like body interferes with these works. Therefore, in such a case, the string-like body can be removed by removing one of the long members from the horizontal member, so that the worker can perform the cleaning work, the rust-proof coating work, etc. without any trouble. Can do.
