Description

  The present invention is a bird damage that can effectively prevent a ground fault accident caused by a bird such as a crow nesting by being fixed to a utility pole, a steel tower, etc., or by causing other creatures to ground between a brace and an electric wire. The present invention relates to a prevention device.

Electric poles and steel towers are easily used as nesting and flying places by birds such as crows and cormorants. For example, an arm attached to a steel tower or a metal arm attached to a steel tower, and when a nest that accumulates wires, tree branches, grass, leaves, etc. is formed on an electric wire, etc., these are conductors around the arm metal. It often causes power line accidents that cause ground faults between parts. In addition, the bird itself may come into contact with or over approach the high-voltage electric wire or the like, resulting in a distribution line accident that causes the conductor portion to ground. For this reason, various proposals have been conventionally made to prevent bird damage.
For example, Patent Document 1 describes a bird damage prevention device including a bird-proof module in which bird-shaped needle-shaped protrusions are provided at predetermined intervals on the surface of a strip-shaped flat protrusion base. The bird damage prevention device is obtained by attaching a bird protection module to an arbitrary portion of a flexible support rod that can be manually deformed with a belt-like fastener. The support rod can be appropriately deformed according to the shape of the protected equipment, and the protected equipment provided with the bird damage prevention device is prevented from being physically used by birds to prevent bird damage.
Further, for example, Patent Document 2 describes a bird harm prevention tool including a main body portion and a nut imitating the eyes of an animal that birds avoid. The nut is internally threaded so as to be screwed into a bolt already attached to a power transmission tower or the like, and can easily be additionally attached to the tip of the bolt. By attaching to power transmission towers, etc., birds are prevented from getting close by keeping them away.

The bird damage prevention apparatus 1 according to the present invention includes a metal base member 10 and a bird repelling unit 20 fixed to the base member 10, and a utility pole, a power transmission tower, or a drawer iron structure of a power generation / substation. It is fixed to the iron material 50 which comprises.
The base member 10 is a member that extends the bird repelling unit 20 away from the iron material 50. According to the place where the bird damage prevention apparatus 1 is installed, the shape is appropriately bent. The base member 10 is a substantially crank-shaped plate member having a co-tightening hole 11 for co-fastening with the iron material 50 at a part (one end portion) thereof and a hole 12 at another portion (the other end portion). . Bolts 51 that are screwed onto the iron material 50 that constitutes a steel tower or the like are inserted into the co-tightening holes 11, and are fastened and fixed together by a nut 52 and a drop-off prevention nut 53. A bird repelling unit 20 is fixed in the hole 12. The base member 10 can be attached by changing its direction freely 360 degrees with respect to the circumferential direction of the bolt 51. In addition, one end of the plurality of base members 10 can be overlapped and fixed to one bolt 51.
The bird repelling unit 20 includes a bar 21 inserted through the hole 12 of the base member 10, a bird repelling member 31 inserted through the bar 21, a spacer 37 inserted between the bird repelling member 31, and a bar In order to prevent the bird repelling member 31 from falling off from the end portion of the member 21, a dropping prevention member 38 is provided that is detachably attached to the rod end portion.

As shown in FIG. 2, the bar 21 is a metallic member having a bolt part 22 at one end and a non-cylindrical part (polygonal columnar part) 23 at another part. In FIG. 2, as an example of the bar 21, the non-cylindrical portion 23 has a rectangular cross section. The bolt portion 22 is inserted into the hole 12 of the base member 10 and is screwed to the nut 13 and the drop-off preventing nut 14 to be fixed to the base member 10. The other end of the bar 21 has a locking hole 24 for locking the drop-off prevention member 38.
The bird repellent member 31 includes a bird repellent piece 32 and a bird repellent mark display member 33.
As shown in FIG. 3, the bird repellent piece 32 includes an insertion hole 32 a that is inserted into the non-cylindrical part 23 of the bar 21 and is restricted in rotation, and is inserted into the non-cylindrical part 23. 21 is a metallic member having a protruding portion 32b protruding in the radial direction. The tip of the bird repellent piece 32 is provided with a sharp point 32c to prevent bird nesting. The insertion hole 32 a has a shape that fits into the cross-sectional shape of the non-cylindrical portion 23. Bird repellent piece 32 is good also as a structure which protrudes not only in one direction but in multiple directions.

  The bird repelling mark display member 33 is a metallic member provided with an insertion hole 33a inserted through the non-cylindrical portion 23 of the bar 21 at substantially the center. The insertion hole 33a has a shape that fits into the cross-sectional shape of the non-cylindrical portion 23, and is inserted into the non-cylindrical portion 23 to restrict rotation. On the surface of the bird repellent mark display member 33, an animal's eyes 33b that the birds repel are drawn by a polarizing paint to prevent the birds from approaching and flying. The polarizing paint is visualized by generating an interference wavelength due to a spectral effect, and has a feature that the color changes depending on the viewing angle and how the light strikes. Due to this feature, the color of the animal's eyes 33b changes as birds approach the bird harm prevention apparatus 1. Since the illusion that the animal eyes 33b are the eyes of living animals can be given to the birds, the repelling effect can be enhanced. As the polarizing paint, for example, Majora (registered trademark) manufactured by Nippon Paint Co., Ltd. can be used.

The bird repelling mark display member 33 can have various shapes, and can be selectively used according to the purpose of use.
For example, as shown in FIG. 4A, a pattern 33b that resembles the eyes of an animal may be drawn on the surface of the bird repellent mark display member 34 having a flat plate shape, for example, a disk shape. It is good also as shapes, such as not only a disk shape but a polygon, a star shape. When the bar 21 is installed substantially vertically, birds can be prevented from approaching from above.
Further, as shown in FIG. 4 (b), an animal eye 35b may be drawn on the surface of the inverted rod-shaped bird repellent mark display member 35 having a disc portion at the center. Moreover, as shown in FIG.4 (c), it is good also as the bird repellent mark display member 36 of the shape provided with the cylindrical drooping part 36d in the edge of the reverse hook-shaped part 36c which has the disc part in the center. When the bar 21 is installed substantially vertically, birds can be prevented from approaching from above and from the horizontal direction. The shape of the disk portion is not limited to a circle, and may be a polygon or other shapes.
If any of the bird repellent mark display members has a diameter (or the length of the corresponding portion) of about 10 cm, it is possible to obtain a bird repellent effect.
Further, the color of the bird repellent mark display member 33 may be changed between a plane, a slope, and a vertical plane. Further, the color of the animal's eyes may be changed alternately, or all colors may be different depending on the position. Further, a relatively light color may be used for the color of the base portion so that the eyes of the animal are crimson. If it does in this way, the eyes of an animal will look conspicuously large and the repelling effect can be heightened.

The spacer 37 is a metallic member provided with an insertion hole 37 a having a shape that fits into the cross-sectional shape of the non-cylindrical portion 23. The spacer 37 adjusts the number of the bird repellent pieces 32 and adjusts the distance between each bird repellent piece 32 and the bird repellent mark display member 33 and the distance from the iron material 50.
The drop prevention member 38 is inserted into the locking hole 24 to prevent the bird repelling member 31 from dropping. As the drop-off prevention member 38, a drop-off prevention pin (split pin) in which a wire-like metal member has a substantially Ω shape can be used (see FIG. 1A).

The power transmission tower to which the bird harm prevention apparatus 1 described above is mounted will be described with reference to FIG. 6A and 6B are diagrams for explaining a power transmission tower, where FIG. 6A is a schematic front view, FIG. 6B is an enlarged view of the armrest portion, and FIG. 6C is a plan view of the armrest portion. .
As schematically shown in FIG. 6A, the power transmission tower 70 is an abdomen composed of four main pillar members 71 and a plurality of diagonal members 72a and horizontal members 72b fixed between the main pillar members 71. And a brace 73 on which three wires are fixed on the left and right sides of the main pillar 71 and on which a ground wire made of an overhead ground wire or an electric wire is laid.
Here, the main pillar 71 is made of iron angle steel, a circular steel pipe or the like, the lower end is supported on the ground by the basic structure, and is erected so as to be directed substantially vertically upward.
The abdomen is made of iron angle steel, and both ends are fixed to the main column 71 via a plate 74 with a plurality of bolts and nuts to form a truss structure between the main columns 71.
As shown in FIGS. 6 (b) and 6 (c), the arm metal 73 is made of iron angle steel, includes an arm metal main material 73 a and an arm metal suspension material 73 b, and extends to the outside of the main pillar material 71. In this manner, the main column member 71 is fastened with a plurality of bolts and nuts (indicated by circles) through the plate 74.
Generally, the electric wire is supported on both end sides of the arm metal 73 with a plurality of insulators interposed in a step shape. In addition, as a method of supporting the electric wire to the arm metal 73, there are a suspension system in which an insulator is suspended in a vertical direction and a tension system in which an insulator is attached to the tip of the arm metal 73 in a substantially horizontal direction. The overhead ground wire is supported on the top of the tower without going through the insulator.
In this way, the power transmission tower 70 is formed by bending a long flat metal plate having a thickness of approximately 1 cm mainly 90 ° in the lateral direction, at least the structural material other than the main pillar 71 standing in the vertical direction. A number of bolts and nuts are used for connecting and joining the angle steels or the angle steel and the main pillar 71 via a plate 74 or the like.

The above-mentioned power transmission tower 70 includes a portion that birds prefer to nest and a portion that is relatively rarely nested.
For example, the tower inner side A where the main pillar 71, the brace main 73a, and the plate 74 are located is a highly stable portion of the power transmission tower 70, and is a portion that birds particularly prefer to nest. Therefore, the bird repelling unit 20 having at least the bird repelling piece 32 is attached mainly for the purpose of preventing nesting. The place where the bird damage prevention apparatus 1 is attached can be physically disabled by the bird repellent piece 32. The distance from the iron material 50 to the bird repellent piece 32 is determined according to the type of bird expected to nest. For example, in order to prevent spider nesting, a repellent piece is attached to a location separated from the iron material 50 by about 10 cm or more. In addition, when the bird repelling mark display member 33 is attached, it is effective because it can prevent birds from approaching and prevent approach.
The arm metal tip B of the arm metal 73 is a place where nesting is relatively rare even when birds approach. Therefore, the bird harm prevention apparatus 1 provided with the bird repelling mark display member 33 for preventing the birds from approaching and flying is attached to the armrest tip B. Bird repellent mark display members 35 and 36 are attached to the armor tip B so that the bird damage prevention apparatus 1 can be viewed from each direction.

Whether or not the bird repellent piece 32 is attached can be determined largely by the position of the access blocking mark 75. That is, the bird damage prevention apparatus including only the bird repellent mark display member 33 is provided at the front end side of the approach blocking sign 75, and the bird damage prevention apparatus having the bird repellent piece 32 attached to the center side from the access blocking sign 75. 1 can be attached. The approach blocking sign 75 is a sign that clearly indicates the approach limit in order to prevent an operator from approaching the charging electric circuit during tower work.
The total height of the bird damage prevention apparatus 1 is preferably about 20 cm in consideration of the insulation interval for each voltage.
As described above, the bird damage prevention apparatus 1 according to the present embodiment includes the united bird repelling unit 20, so that the bird repelling piece 32, the bird repelling mark display member 33, and the spacer 37 depending on the installation location and purpose. By appropriately combining the above, it is possible to take measures against bird damage according to the purpose. Moreover, since it is attached only by fastening together to the location fixed using the volt | bolt, a special tool and skill are not required and installation is easy.
