It is a side view of a comparative example.

Hereinafter, the present invention will be described in detail based on illustrated embodiments.
As shown in FIGS. 1 and 2, the bird-preventing device according to the present invention includes a plurality of upwardly projecting needles 11, a base end connecting member 15 that connects base end portions of the plurality of needles 11, and Is integrally formed of an insulating resin. The needle 11 is formed in a conical shape having a tapered outer peripheral surface that gradually decreases in diameter from the proximal end (lower part) to the distal end (upper part), and the top part is formed in a round mountain shape. The proximal end connection member 15 includes a longitudinal connection member 12 that connects the plurality of needles 11 in the longitudinal direction N, and a width direction connection member 13 that connects the plurality of needles 11 in the width direction W. .

The plurality of needles 11 are arranged in the longitudinal direction (vertical direction) N. This column in the longitudinal direction N is called a column.
The bird guard 1 has a plurality of columns. Specifically, a vertical row is constituted by 5 or more and 25 or less needles 11, and three rows are provided.
In each longitudinal row (longitudinal row), the height Ha of the endmost needle (vertical end needle) 11A disposed at the endmost portion (both ends) in the longitudinal direction N is set to the longitudinal intermediate needle in the intermediate portion in the longitudinal direction N. It is set smaller than the height dimension Hb of 11B.

In other words, the height dimension Ha of the endmost needle 11A is set smaller than the height dimension of the vertical center needle 11 (11E). The vertical center needle 11E is a needle 11 disposed in the center when the number of needles 11 constituting a vertical row is an odd number, and the center in the longitudinal direction N when the number of needles 11 constituting a vertical row is an even number. Say two adjacent to the line.
Here, when the number of the needles 11 constituting the vertical row is an odd number, the vertical intermediate needles 11B are a total of five, including the vertical central needle 11E and two longitudinally adjacent needles 11E in the longitudinal direction. Hb is the average height of the five. When there are an even number of needles 11 constituting one vertical row, the total is 6 in the longitudinal direction centering on the vertical central needle 11E, and the height dimension Hb is the average height of the 6 needles. When the average height is obtained, the needle 11 whose height dimension is 1.5 times or more of the other needles 11 out of the plurality of needles 11 serving as the longitudinal intermediate needle 11B is ignored.

Further, a plurality of needles 11 (a predetermined number) disposed at the longitudinal end 1E are provided such that the height dimension gradually decreases toward the outermost needle 11A.
In this way, the overall shape is formed in a trapezoidal shape in a side view. In other words, as shown by a two-dot chain line in FIG. 1, a virtual ridge line connecting the apexes of the needles 11 constituting each column in a side view (connecting apexes of adjacent needles 11 in the longitudinal direction N, and The imaginary line connecting the endmost needles 11A, 11A) is parallel to the installation surface G, and the bottom-bottom straight portion and the top-bottom straight portion, and the end of the top-bottom straight portion toward the extreme end in the longitudinal direction. And a pair of inclined line portions inclined downward, and is formed in a trapezoidal shape.

  As shown in FIGS. 2 to 4, the width direction connecting member 13 for connecting the base end portions of the plurality of needles 11 is integrally formed of an insulating resin. The plurality of needles 11 are juxtaposed in the width direction (lateral direction) W. This arrangement may be called a row or “row”. Specifically, a horizontal example (one line) is constituted by three needles 11.

As shown in FIGS. 3 and 4, in each row (one row), the height Hc of the lateral end needle 11C disposed at the outermost end (both ends) in the width direction W is set to the middle in the width direction W. Is set smaller than the height dimension Hd of the horizontal intermediate needle 11D.
Further, the height dimension Hc of the lateral end needle 11C is set shorter than the height dimension of the lateral center needle 11 (11J).

In addition, when viewed from the front, the overall shape is a nail tip type (drill tip type). In other words, as shown by a two-dot chain line in FIG. 3, a virtual ridge line connecting the vertices of the needles 11 constituting each row in front view (connecting the vertices of the adjacent needles 11 in the width direction W, and An imaginary line connecting the lateral end needles 11C and 11C) and an inclined line part inclined downward from the apex of the center needle 11J toward the extreme end in the width direction, and a lower bottom straight part parallel to the installation surface G And is formed in a triangular shape. Moreover, as shown in FIG. 4, it can be said that the cross-sectional shape is formed in a mountain shape.
Although not shown, the height of the needles 11 in each row may be the same, and the overall shape may be rectangular when viewed from the front.

Next, another embodiment will be described.
As shown in FIG. 5, the overall shape is formed in a semicircular shape (arch shape or bowl shape) in side view. That is, the virtual ridgeline connecting the apexes of the needles 11 constituting each column in a side view, as it goes from the central portion in the longitudinal direction toward both extreme ends, the arcuate line portion that approaches the installation surface G, and the installation surface G Are formed in a semicircular shape (arch shape or bowl shape). Other configurations are the same as those of the embodiment of FIGS.

Next, another embodiment will be described.
As shown in FIG. 6, the overall shape is formed in a triangular shape in a side view. That is, the virtual ridgeline connecting the apexes of the needles 11 forming each column in a side view is a pair of inclined line portions that are inclined downward from the longitudinal center to the longitudinal end, and the installation surface G. And a parallel bottom-bottom straight portion, and is formed in a triangular shape that is pointed upward. Other configurations are the same as those of the embodiment of FIGS.

Here, the action of the parking bird arrester 1, and, in order to facilitate describing the parking bird preventing structure of the present invention will be described in comparison with parking bird preventer 1 'of the comparative example shown in FIG.
In the comparative example shown in FIG. 9, the overall shape is formed in a rectangular shape in a side view. That is, the height dimensions of the needles 11 are all the same, and the height dimension Ha ′ of the endmost needle 11′A is set to be the same as the height dimension Hb ′ of the longitudinal intermediate needle 11′B. That is, the ridge line connecting the apexes of the needles 11 constituting the column is formed in a straight line parallel to the installation surface G in a side view.

  In FIG. 7, the bird guards 1 and 1 ′ are disposed on the upper surface (installation surface G) of a brace of a power transmission building such as a utility pole or a steel tower that is desired to prevent bird parking. Since the insulator 9 that supports the electric wire 8 is erected on the arm metal, it is necessary to separate the electric wire 8 from the electric wire 8 by a specified separation dimension R or more.

With the specified separation dimension R, the electric wire 8 is supported on the space side (also referred to as the predicted bird parking position side or the bird parking space side) where bird watching should be prevented when viewed from the center line S9 of the insulator 9. It is the distance (dimension) from the center of the assumed electric wire 8. When the working voltage is a high voltage (6.6 KV), for example, it is set to 50 mm. The extra high pressure (20 KV class) needs to be separated from that at 6.6 KV.
That is, assuming an access prohibition space having a circular shape in a side view centered on the electric wire 8 with the specified separation dimension R, and placing the bird guard 1 in the access prohibition space, the insulator 9 and the electric wire 8 are adversely affected. Since there is a possibility, construction is prescribed so as to prohibit the arrangement.
Moreover, the installation surface parallel dimension between the longitudinal direction endmost part of the bird parking prevention tool 1 and the bird parking predicted position side endmost part 9a of the insulator 9 is called the insulator separation dimension L.

  First, in FIG. 7, the comparative example indicated by the two-dot chain line is disposed away from the center of the electric wire 8 by a specified separation dimension R. That is, the shortest distance from the center of the electric wire 8 to the endmost needle 11 ′ A is arranged so as to have the specified separation dimension R. The insulator separation dimension L at this time is referred to as a first insulator separation dimension La.

And if the bird parking prevention tool 1 according to the present invention is arranged with the same lever separation dimension L (first insulator separation dimension La) as the comparative example from the bird parking predicted position side end 9a of the insulator 9, The portion that is the shortest distance from the center of the electric wire 8 is the top portion 10 of the endmost needle 11 (11A) , and the size thereof is a wire separation dimension Q that is larger than the specified separation dimension R. Therefore, it is possible to approach the insulator 9 further than the position of the solid line in FIG. 7, and therefore, it is installed close as shown in FIG.

In FIG. 8 where the distance from the center of the electric wire 8 to the top 10 of the endmost needle 11 (11A) of the bird guard 1 is the specified separation dimension R, the insulator separation dimension L is the first. The second insulator separation dimension Lb is shorter than the insulator separation dimension La.
In other words, while the distance from the electric wire 8 is maintained at the specified separation dimension R (observing the construction regulations), it can be disposed close to the insulator 9, and the bird parking space is eliminated (narrowed) to ensure that the bird is parked. To prevent.

  In addition, as shown in FIG. 3, since the ridge line connecting the apex of the horizontal end needle 11C and the horizontal intermediate needle 11D is downwardly inclined, fallen leaves, branches, etc. naturally fall along the ridge line and accumulate. Therefore, it is possible to prevent troubles such as maintenance, and fallen leaves and branches from accumulating and contacting the insulator 9 and the electric wire 8.

In other words, as shown in FIG. 8, the bird parking prevention structure of the present invention is a structure in which the bird parking prevention tool 1 is disposed close to the insulator 9 to prevent bird parking.
Since it is necessary to dispose with a specified separation dimension R according to the construction regulations, the comparative example shown by the two-dot chain line in FIGS. There was a risk that birds such as On the other hand, in the present invention, the position of the top portion 10 of the endmost needle 11 (11A) is disposed at a position lower than the assumed position of the center of the electric wire 8, and has a specified separation dimension R from the center of the electric wire 8. The outermost needle 11 (11A) is inserted between the lower half circle (the semicircle on the ground surface G side) and the installation surface G (the upper surface of the bracelet) formed in the side-view circular access prohibition space. Thus, the lever separation dimension L is shortened to narrow (eliminate) the bird parking space, thereby reliably preventing bird parking.

  Note that the means for fixing the bird guard 1 to the arm can be fixed by screwing it through a metal fitting that holds the longitudinal direction connecting member 12 and the width direction connecting member 13 from below, or a U-shape. Fixing with clamp metal fittings, fixing with adhesive tape, adhesive, resin binding band, etc. is free.

  The present invention can be changed in design, and is not limited to the embodiment in which the illustrated column is three columns, and the column may be only one column, two columns, or four columns or more. Further, the shape of the top portion 10 of the needle 11 may be a conical shape having a sharp point or a sword shape. The needle 11 may be formed in a quadrangular pyramid shape. The needle 11 may be a round bar type or a square bar type having a straight outer peripheral surface. As shown in the figure, the base end connecting member 15 is not limited to the shape in which the longitudinal direction connecting member 12 and the width direction connecting member 13 are arranged in a rectangular shape in a plan view, and the shape arranged in a U shape in a plan view, A plurality of needles 11 may be connected by arranging the longitudinal direction connecting member 12 and the width direction connecting member 13 in an uneven wave shape in a plan view. The proximal end connecting member 15 may be formed in a strip shape. Further, the longitudinal direction connecting member 12 and the width direction connecting member 13 are free to have a bowl-like shape, a rod-like shape, a plate-like shape or the like (a plan view shape or a cross-sectional shape). In FIG. 3, a virtual ridge line connecting the vertices of the needles 11 constituting each row in front view (the vertices of the adjacent needles 11 in the width direction W are connected, and the lateral end needles 11C and 11C at both ends are connected. (Virtual line connecting the two) may be formed in a trapezoidal shape or a semicircular shape. That is, it is only necessary that the ridge line is formed so as to have a line part inclined downward from the center part and accumulation of fallen leaves or the like can be prevented. The material for the bird guard 1 is an insulating material such as plastic, for example, polypropylene.

As described above, the bird parking prevention device 1 includes a plurality of upward projecting needles 11 and a base end connecting member 15 that connects base end portions of the plurality of needles 11 formed of an insulating resin. It is a bird preventer, and a plurality of needles 11 are arranged in the longitudinal direction N, and the height Ha of the most distal needle 11A disposed at the extreme end in the longitudinal direction N is set to an intermediate portion in the longitudinal direction N. Since the height Hb of the vertical intermediate needle 11B arranged at the top is set smaller than that of the vertical intermediate needle 11B, the endmost needle 11A can be placed close to the insulator 9 such as a utility pole or a steel tower, and there is a possibility that birds will park there. By eliminating the bird space, it is possible to prevent the birds from being parked. There is no possibility of adversely affecting the electric wires 8 and the insulators 9, and it is possible to obtain a safe bird prevention effect.

  In addition, the anti-birding structure of the present invention includes a plurality of upwardly projecting needles 11 and a base end connecting member 15 that connects base end portions of the plurality of needles 11 integrally formed with an insulating resin. The bird guard 1 is provided with a plurality of needles 11 arranged in the longitudinal direction N, and the height dimension Ha of the endmost needle 11A disposed at the farthest end in the longitudinal direction N is the same. The bird guard 1 is set to be smaller than the height dimension Hb of the longitudinal intermediate needle 11B disposed in the middle part in the longitudinal direction N. Since the endmost needle 11A is arranged close to the insulator 9 with a specified separation dimension R, the endmost needle 11A can be arranged close to the insulator 9 such as a utility pole or a steel tower. It is possible to reliably prevent the birds from being parked by eliminating the bird parking space where there is a risk of being parked. There is no possibility of adversely affecting the electric wires 8 and the insulators 9, and it is possible to obtain a safe bird prevention effect.
