Description

  The present invention relates to a bird harm prevention device for preventing birds from stopping on a linear or rod-shaped body. More particularly, the present invention relates to a bird harm prevention device which is easily attached and detached and is attached so as to go around a linear body or a rod-shaped body.

Electricity generated at the power plant is sent to households via transmission lines and distribution lines, but the electric wires are spread around various places, and in some places birds stop on the electric wires and the electric wire deteriorates due to bird droppings However, the surrounding environment has deteriorated, and power outages caused by electric shocks to birds have become problems.
Various methods have been considered to solve these problems. As one of the methods, for example, there is a method of winding a wire around a wire (Patent Document 1). However, the completed coil cannot be fitted to the already stretched wire, and one wire is wound around the wire at the site. Since it is wound in a coil shape, it takes a lot of trouble and is not realistic. A method of attaching an electric wire to a coil using a special fixture is also considered (Patent Document 2). However, there is a problem that a simple structure including only the coil is originally complicated and an extra weight load is applied to the electric wire. . Furthermore, the cited document 2 attaches the coil to the electric wire with a fixture provided at the lower part of the coil, but in this case, the coil is arranged on the electric wire, and the structure itself of surrounding the electric wire with the coil also changes. Would.

  An object of the present invention is to provide a bird harm prevention device which is easily attached and detached and is attached so as to go around a linear body or a rod-like body capable of stopping birds. More specifically, it is an object of the present invention to provide a bird harm prevention device which is easily detachable and hard to be detached from a linear body or a rod-shaped body.

  As a result of various studies to achieve the above object, the present inventor devised the shape of a wound or board-shaped bird harm prevention device attached so as to go around a linear body or a rod-shaped body, thereby reducing bird harm. The present inventors have found that the linear member or the rod-shaped member can be locked to the preventive device, and have reached the present invention. That is, the present invention is as follows.

1. A single-turn or disc-shaped bird harm prevention body used by attaching a linear or rod-shaped body around which birds can stop, and having a recess for locking the linear or rod-shaped body. A bird harm prevention body.
2. The above-mentioned bird harm prevention body, wherein the recess has a narrow opening and a relatively large depth.
3. A bird harm prevention tool comprising a plurality of the above-mentioned bird harm prevention bodies 1 or 2 connected in a longitudinal direction of a linear body or a rod-shaped body.
4. A coil-like bird harm prevention tool, wherein each winding has a concave portion for locking a linear or rod-like body on which birds can stop.
5. 3. The bird damage preventive device according to the above item 3 or 4, wherein each concave portion has an opening shifted from each other.

  ADVANTAGE OF THE INVENTION According to the bird harm prevention device of this invention, the effort which attaches the winding or board-shaped bird harm prevention device attached so that it circulates to a linear body or a rod-shaped body is reduced significantly. In particular, when the linear or rod-shaped body is an electric wire, when working on the electric wire, it is very important to improve the workability by reducing the time and effort since the insulation protective clothing is worn. Winding or board-shaped bird harm prevention devices that have been considered unrealistic, such as windings or board-shaped bird harm prevention devices for electric wires, can be realized.

Hereinafter, the present invention will be described in detail.
1 to 4 show examples of the bird harm prevention body and the bird harm prevention device of the present invention. By connecting a plurality of bird harm prevention bodies in the longitudinal direction of the linear body or the rod-like body, a bird harm prevention tool is obtained.
When connecting the bird harm prevention bodies, the bird harm prevention bodies may be connected to each other via the connecting tool 11 or the connection component 13 (FIGS. 1 and 3) (FIG. 2). Moreover, you may connect each bird damage prevention body with a rope. For example, the bird harm prevention body is provided with a loop through which a rope is passed, and one rope is passed through the loop one after another to connect the ropes. In this case, it is preferable that the position of the bird harm prevention body can be fixed by tightening the ring. FIG. 4 shows a bird harm prevention device integrally formed in a coil shape from the beginning.
If a coupling is used, the distal end can be treated, for example, with a distal coupling 12 (FIG. 1B12).
A structure in which a protrusion projects upward so that birds are hard to stop (for example, FIG. 2). The number of projections may be one or more. The projection may be directed in any direction as long as it is upward from the horizontal. The projection is more preferably a needle-like projection having a sharp tip.
Further, if a plurality of bird harm prevention bodies are connected, a bird harm prevention body is formed by connecting a plurality of bird harm prevention bodies, and in the case of FIG. 1B or FIG. 2B, it can also be called a coiled bird harm prevention body. When connecting a plurality of birds in advance, it is preferable that the bird harm prevention tool be compact for convenient transportation. In this regard, the bird harm prevention device shown in FIGS. 1, 2, 4, or connected with a rope can be contracted in the longitudinal direction of the linear body or the rod-shaped body, and can be made compact.
The winding or the coil is attached so as to go around the linear body or the rod-like body, but does not go around completely, and, as a matter of course, the circumference of the concave portion is interrupted (for example, FIGS. 1 to 4).
Although the winding shape of the bird harm prevention body and the bird harm prevention device shown in FIGS. 1 to 4 are all circular, the winding shape is not particularly limited, and may be any of a circle, an ellipse, various polygons, and a star. However, if the outer periphery is curved, it is considered that the bird is hard to stop, and the winding shape is more preferably a circle or an ellipse.
Further, the bird harm prevention body and the bird harm prevention device do not necessarily have to be in the shape of a roll, and may be formed in a disk shape, for example, in a disk shape, and may be attached to a linear or rod-shaped body. . Further, the surface of the board may be slightly uneven.

  The length of the bird harm prevention device in which a plurality of bird harm prevention bodies are connected in series or the coiled bird harm prevention device that is coiled from the beginning is not particularly limited, but the length in the long direction is not particularly limited. Therefore, it is more preferable that the length is not too long. For example, the length at the time of mounting with the coil extended may be about 3 m or 5 m.

  There is no particular limitation on the number of turns per unit length when the bird harm prevention device is attached, but if the number of turns is small, birds may enter between each turn, and even if the number of turns is too large Therefore, it is more preferable to set the winding interval such that small birds cannot enter and crow's feet cannot enter during installation. For example, since the crow's foot width is about 40 mm, the winding interval is about 40 mm or slightly narrower. Similarly, the interval between the boards in the case of a board shape can be considered.

It is preferable that the concave portion has a narrow opening which becomes a passage when the linear body or the rod-shaped body is attached / detached, and a relatively wide linear body or the rod-shaped body holding portion is disposed at the back. With this configuration, once the linear body or the rod-like body is fitted into the holding portion, the linear body or the rod-like body is hardly detached because it is blocked by the narrow opening. For example, as shown in FIG. 6, when the concave portion 1 is Ω-shaped, the Ω-shaped neck portion 2 serving as the opening is temporarily expanded, and the electric wire is fitted into the Ω-shaped head portion 3. Blocked by the narrow neck, the wires are less likely to come off.
Furthermore, the neck portion of the concave portion may be swaged to make it difficult for the electric wire to come off. For example, the neck portion may be sandwiched between the clips 8 (FIG. 7). In addition, if the center of gravity of the bird harm prevention body or the bird harm prevention device is lowered, the opening becomes difficult to face upward, and the electric wire is hardly detached.
When the bird harm prevention body or the bird harm prevention tool has a disk shape, the concave portion is formed as if it were hollowed out.

  By slightly shifting the opening of the concave portion of each winding or board, the linear body or the rod-shaped body is less likely to be displaced. For example, the openings of the Ω-shaped recess are shifted by several degrees along the circumference so that the openings are not aligned in one direction (FIG. 8). Then, since the openings do not align and do not open downward, the wires are less likely to come off (FIG. 9).

  More preferably, the linear or rod-shaped body holding portion of the concave portion is arranged near the center of the outer periphery of the winding or the board. If it is located near the center, the linear body or rod-shaped body will be located near the center of the outer periphery of the winding or board, and even if the bird harm prevention body or the bird harm prevention tool rotates, the outer circumference of the winding or board will be Since the bird is always kept at a certain distance from the linear body or the rod-shaped body, the bird is less likely to stay on the linear body or the rod-shaped body. For example, as shown in FIG. 6, when the concave portion 1 has an Ω shape, if the Ω-shaped head portion 3 holding the electric wire is formed concentrically with the coil, the electric wire will be located at the center axis of the coil. Even if the coil rotates due to the wind or the weight of the bird, the outer periphery of the coil is always kept at the same distance from the electric wire, so that the bird is hard to stop on the electric wire.

  The size of the portion of the bird harm prevention body or the bird harm prevention device of the present invention that holds the linear body or the rod-shaped body may be adjusted according to the linear body or the rod-shaped body, or may be adjusted according to some standards. It is more preferable to adjust the thickness according to the thickness of the object, because it can accommodate a thin linear body or a rod-like body. For example, the Ω-shaped head portion 3 in FIG. 6 may be adjusted in size according to the thickness of the electric wire. It is more preferable because it can handle thin electric wires. Since electric wires having an outer diameter of 20 mm or 40 mm are frequently used as power transmission lines, the size of the portion holding the linear body or the rod-shaped body may be adjusted according to the electric wire having an outer diameter of 40 mm.

  There is no particular limitation on the shape of the linear body or the rod-like body holding portion of the concave portion, and it may or may not match the cross-sectional shape of the linear body or the rod-like body. For example, it may be circular in accordance with the cross-sectional shape of the electric wire, or may be polygonal in order to prevent twisting of the electric wire.

The upper portion of the concave portion may be weakened by being rubbed with the linear member or the rod-shaped member, and therefore, it is more preferable to reinforce the portion. For example, a tubular reinforcing material 9 is fitted so as to cover a portion above the concave portion (FIG. 10A). The reinforcing material 9 has a slit 10 in the upper part, and if this slit is partially narrowed (FIG. 10B), it is easy to fit into a linear body or a rod-shaped body and becomes difficult to remove.
In addition, this portion may have a structure that is resistant to abrasion in advance when the bird harm prevention body or the bird harm prevention device is manufactured. For example, in the case of a resin material, it is conceivable to integrally mold the reinforcing member or make this portion thicker than the surroundings.

  The material of the bird harm prevention body and the bird harm prevention device of the present invention is not particularly limited, such as resin, metal, and a composite material containing them, but from the viewpoint of ease of processing, it is preferable to use a resin or a composite material thereof. More preferred. The resin used is not particularly limited, and may be a thermoplastic resin or a thermosetting resin. For example, polyethylene terephthalate, polyethylene, polycarbonate, polyamide (nylon), or the like may be used as long as it is a thermoplastic resin. The molding method is not particularly limited, but may be, for example, extrusion molding or injection molding.

  The object to which the bird harm preventive body and the bird harm preventive device of the present invention are attached, that is, the linear body or the rod-shaped body is mainly a transmission line or a distribution line of an electric power company. Can be mounted anywhere without use. For example, it can be attached to a telephone pole, a tower, or a suspension line of a train.

When mounting the bird harm prevention device of the present invention, a linear or rod-shaped body is fitted into the concave portion and mounted. When connecting multiple bird harm prevention bodies to form a bird harm prevention tool, it is recommended that the bird harm prevention bodies be connected to each other in advance and used as a bird harm prevention tool. More preferred.
For example, a bird harm prevention body (FIGS. 1 to 3) is connected in advance at a factory until a suitable length is obtained, and the bird harm prevention device is prepared. This is carried to the site, carried to a place where the electric wire is stretched, and the neck portion 2 (FIGS. 1 to 3) of the Ω-shaped recess is expanded, and the first winding is fitted to the electric wire. Next, while expanding the neck part, the subsequent windings are inserted one after another. After insertion, one end is fixed, the coil is extended in the direction of the electric wire, and the other end is also fixed. Further, the intermediate portion may be fixed if necessary. The end may be hooked in advance, for example, and connected to an adjacent coil or telephone pole. The terminal or the intermediate portion may be fixed with a wire, a binding band, a wrapping tie or the like, or may be fixed with a jig 5 to the electric wire (FIG. 11). When wires are used, it is preferable that they are attached to the bird harm prevention device at regular intervals, because they do not have to be provided as separate components. When using a jig, the shape of the jig is not limited. For example, a bird damage prevention tool may be fixed by a roof type (FIG. 11A) and a fastener 7 (FIG. 11B). The jig 5 is arranged on the electric wire 4 so as to sandwich the upper portion 6 of the concave portion of the bird harm prevention device (FIG. 11C), and is fixed with the fastener 7 (FIG. 11B).
In the case of the coiled bird harm prevention device, the connecting work is not necessary, but the other parts are installed like the bird harm prevention body.
In this way, it is troublesome to simply fit the concave portion in order to mount the linear or rod-shaped body, for example, to expand the neck portion 2 (FIGS. 1 to 4) of the ohmic concave portion, fit it to the electric wire, and fix the end. The bird harm prevention device can be attached to the electric wire in a small number of ways.

If the bird harm prevention device of the present invention is used, the bird cannot approach the linear member or the rod member, and cannot stop at the linear member or the rod member. In addition, even if it tries to stop at the bird harm prevention device, it cannot be stopped because the bird harm prevention device is unstable as a scaffold.
For example, in the case of a coil-shaped bird harm prevention device, the bird cannot approach the linear body or the rod because the coil surrounds the linear body or the rod. Even if the coil rotates due to wind or the like, the coil continues to surround the linear body or the rod-shaped body, and thus cannot remain at the linear body or the rod-shaped body. Furthermore, even if it tries to stop at the coil, the coil is unstable and cannot be stopped at the coil by deforming, swinging or rotating under the weight of the bird.
Further, when the wind blows, the linear body or the rod-like body shakes, and the coil expands and contracts, so that it has an effect of intimidating a bird.

  According to the bird harm prevention device of the present invention, bird harm due to bird droppings or electric shock of birds can be prevented, so that it is useful for maintenance and management of transmission lines, distribution lines, telephone lines, and the like suffering from bird harm.
