  For the above purpose, a plurality of needle-like members are attached to the upper surface portion of the ring-like attachment member formed with an opening for insertion through an electric wire with a gap, and are gripped with an insulating jacket and are used for indirect hot wire work. It realized by attaching the plate-shaped member for attaching a harm prevention tool to an electric wire to the lower surface part of an attachment member.

Embodiments of the bird harm prevention device of the present invention will be described below with reference to the drawings.
The bird harm prevention tool 10 according to one embodiment of the present invention is made of resin, and as shown in FIG. 1A, a ring-shaped mounting member 11 and an upper surface portion (upper half portion) of the mounting member 11 ) And three needle-like members 12 (thorns) attached at intervals, and an inverted trapezoidal plate-like plate-like member 13 attached to the lower surface portion of the attachment member 11.

Here, the inner diameter of the attachment member 11 is the same as or slightly smaller than the diameter of the peripheral wire 1 to which the bird harm prevention tool 10 is attached. For example, when the bird harm prevention tool 10 is attached to the peripheral wire 1 having a thickness of 200 sq, the inner diameter of the attachment member 11 is set to 2.1 to 2.0 cm.
The mounting member 11 has a width equal to or greater than the lateral width of the upper surface of the plate-like member 13 = 2 cm (see FIG. 1C).
On the obliquely lower side of the mounting member 11, an opening 11 a for insertion into the mounting member 11 through the peripheral wire 1 is formed by cutting out about ¼ of the ring member constituting the mounting member 11. .

  As shown in FIG. 1B, the needle-like member 12 has a cylindrical portion with a length (height) = 2.5 cm and a diameter = 0.5 cm, a length (height) = 1.5 cm, and a bottom diameter. = A conical portion of 0.5 cm, and has a pointed shape.

A disc-shaped Teggs attachment member 14 is attached to a portion 1.5 cm from the bottom of the cylindrical part of the needle-like member 12 and a boundary part between the cylindrical part and the conical part.
The leg attachment member 14 is formed with a linear cut 14a for preventing the teg 20 from being unwound by inserting the end part of the leg 20 (see FIG. 2B) after winding.
The two attachments 14 are attached so that the two attachments 20 can be stretched, and when only one attachment 20 is attached, the height of the attachment can be adjusted. It is to do.

The plate-like member 13 is used to attach the bird harm prevention tool 10 to the peripheral wire 1 by an indirect hot wire operation by holding it with an insulating hat (hot stick).
Therefore, the front surface and the back surface of the plate-like member 13 are roughened so that the insulating jacket does not slip when gripped by the insulating jacket. In addition, as shown in FIG. 1C, the plate-like member 13 has a lateral width of the bottom surface (the surface on the upper side of the inverted trapezoid) = 1.5 cm, a lateral width of the upper surface (the surface on the lower side of the inverted trapezoid) = 2 cm, The height (the height of the inverted trapezoid) = 2.5 cm, the thickness of the bottom surface = 0.2 cm, and the thickness of the upper surface = 0.5 cm.

When attaching the bird damage prevention device 10 to the surrounding wire 1, the plate-like member 13 is gripped with an insulating jacket, and the bird is moved to a position where both ends of the opening 11 a of the mounting member 11 come into contact with the surrounding wire 1. After moving the damage prevention device 10, the bird injury prevention device 10 is pulled obliquely downward toward the front with an insulating rattle to widen the opening 11a with the peripheral wire 1, thereby passing the peripheral wire 1 through the opening 11a. Inserted into the mounting member 11.
Since the opening 11a of the attachment member 11 is closed after the bird damage prevention device 10 is attached to the edge wire 1, the edge wire 1 is securely held by the attachment member 11 and the bird damage prevention device 10 is attached to the edge wire. 1 can be fixed.

As a method of attaching the bird damage prevention device 10 configured as described above to the peripheral wire 1, for example, as shown in FIG. 2A, five bird damage prevention devices 10 are equally spaced (for example, 3 cm intervals). ) May be attached along the longitudinal direction of the peripheral wire 1 or, as shown in FIG. 2 (b), the middle bird prevention device 10 shown in FIG. 2 (a) is prevented. The tool 10 may be omitted, and two tegs 20 may be stretched between the two bird damage prevention tools 10 in the center (in this case, only one of the two tegs 20 is stretched) It is good.)
Also, the two bird damage prevention tools 10 on the left and right shown in FIG. 2B are omitted, and the two bird damage prevention tools 10 at the center are slightly shifted to the left and right, respectively, and attached to the peripheral wire 1. One or two tegus 20 may be stretched between the two bird damage prevention devices 10.

  In addition, since the connection part cover 2 attached to the both ends of the surrounding electric wire 1 has a width of 4 cm to 6 cm on average on the structure, and it is difficult for a bird to grasp with a foot, Birds will not stop even if they are not installed.

  In the above description, the needle-like member 12 to which the teg attachment member 14 is attached is used. However, when the teg 20 is not stretched between the adjacent bird damage prevention devices 10 as shown in FIG. You may use the acicular member in which the teg attachment member 14 is not attached.
