(Composition of bird damage prevention equipment)
First, the configuration of the bird damage prevention device according to the first embodiment of the present invention will be described. FIG. 1 is an explanatory diagram showing a configuration of a bird damage prevention device according to the first embodiment of the present invention.

In FIG. 1, the bird damage prevention device 100 of the first embodiment according to the present invention includes a fixing portion 110 and a repellent portion 120. The fixing portion 110 includes a band-shaped member 111 having a substantially ring shape, and a tightening member 112 having an adjustable inner diameter of the ring shape formed by the band-shaped member 111.

The band-shaped member 111 has a band shape. The band-shaped member 111 can be formed by using a metal material such as stainless steel. Specifically, the band-shaped member 111 has a shape similar to that of a known arm tie band or branch line band, for example.

In the band-shaped member 111, through holes 113 are provided at both ends in the length direction. Both ends of the band-shaped member 111 are bent so as to project toward the outer peripheral direction of the ring formed by the band-shaped member 111 so that the through holes 113 face each other.

The tightening member 112 can be realized by a bolt 114 inserted so as to penetrate each through hole 113 provided at both ends of the band-shaped member 111, and a nut 115 screwed into the bolt 114. .. The tightening member 112 has a ring formed by the band-shaped member 111 by screwing a nut 115 into a bolt 114 inserted so as to penetrate each through hole 113 and adjusting the screwed state of the nut 115 with respect to the bolt 114. The diameter of the can be adjusted.

In a state where the band-shaped member 111 is wound around a utility pole, both ends of the band-shaped member 111 are fixed by adjusting the diameter of the ring formed by the band-shaped member 111 in a smaller direction, and the band-shaped member 111 is attached to the utility pole or the like. Can be fixed to the columnar body of. By configuring the fixing portion 110 with the band-shaped member 111 and the tightening member 112, the configuration can be simplified and the space required for attaching the fixing portion 110 can be suppressed to a small size.

The nut 115 in the tightening member 112 may be fixed to the band-shaped member 111. Specifically, the nut 115 fixes the through hole in the nut 115 to the band-shaped member 111 in a state of overlapping with the through hole 113 of one of the through holes 113 provided at both ends of the band-shaped member 111. ..

This makes it possible to prevent the nut 115 from falling while working on the utility pole. Since the work on the utility pole is performed by wearing thick insulating gloves, by fixing the nut 115 to the band-shaped member 111, it is possible to reduce the burden on the work and improve the work efficiency.

A support member 116 is provided on the outer peripheral surface of the ring formed by the band-shaped member 111. The support member 116 projects from the outer peripheral surface of the ring formed by the band-shaped member 111 toward the outer peripheral surface of the ring, and faces the band-shaped member 111 at a position opposite to the position fixed to the band-shaped member 111. It is provided with a screw hole 117 that is recessed.

A plurality of support members 116 are provided along the length direction of the band-shaped member 111. The plurality of support members 116 can be provided, for example, on the outer peripheral surface of the ring formed by the band-shaped member 111 at equal intervals.

The repellent portion 120 has a rod shape and is attached to the fixing portion 110 at one end in the length direction. The repellent portion 120 includes a screw portion 121 screwed into a screw hole of the support member 116 at one end in the length direction. As a result, the repellent portion 120 can be attached to the fixed portion 110.

The repellent portion 120 is configured by connecting a plurality of core bodies 122 along the length direction. The plurality of core bodies 122 can be connected to each other via, for example, a diversion joint 123. Specifically, the variable joint 123 can be realized by a rod end joint (spherical slide bearing), a knuckle joint (knuckle joint), a clevis joint (U-shaped link), or the like.

For example, by using the rod end joint as the diversion joint 123, the repellent portion 120 can be bent in an arbitrary direction at the connecting portion between the core bodies 122. As a result, it is possible to secure the degree of freedom in adjusting the positional relationship between the core bodies 122. By using the rod end joint as the turning joint 123, it is possible to suppress the increase in size of the connecting portion and receive a large radial load and an axial load in both directions.

Further, for example, by using a knuckle joint or a clevis joint as the diversion joint 123, the core bodies 122 can be connected to each other with a simple configuration. When a knuckle joint or a clevis joint is used as the turning joint 123, the core bodies 122 to be connected rotate around the axis of the connecting pin provided in the knuckle joint or the clevis joint.

When a knuckle joint or a clevis joint is used as the turning joint 123, the joint portion of the knuckle joint or the clevis joint and the core body 122 may be connected in a rotatable state around the axis of the core body 122. As a result, in the modified joint 123, the core body can be rotated in two axial directions around the axis of the connecting pin provided in the knuckle joint and the clevis joint and around the axis of the core body 122. It is possible to prevent the rotating surface of the 122 from being restricted around the axis of the connecting pin, and to secure the degree of freedom in adjusting the positional relationship between the core bodies 122.

Specifically, for example, the joint portion and the core body 122 are connected via a mechanism similar to a bar end used for a motorcycle steering wheel, which is called a collet chuck or the like. As a result, even when a knuckle joint or a clevis joint is used, the repellent portion 120 can be bent in any direction, and the bending direction of the core body 122 is not restricted.

Each core 122 has a plurality of protrusions 124 protruding from the outer surface. The protrusion 124 can be formed by using, for example, a synthetic resin such as polypropylene. By forming the core body 122 with a synthetic resin, it is possible to repel the flying birds without damaging them.
