Description

  The present invention relates to a device that is attached to a utility pole or the like to prevent flying or nesting of birds such as crows.

  In order to prevent situations where crows fly or nest on power poles or steel towers, which could interfere with electrical equipment, or where crow dung is scattered on the ground, birds have traditionally come to power poles or steel towers. Preventive equipment is installed. There are various types of bird flight prevention devices that are commonly used in the past, but they use the property of avoiding the linear bodies in which birds swing irregularly and the loops made of linear bodies. There is one that prevents this (Patent Document 1).

Examples of the above-mentioned bird flying prevention tool include those in which a transparent and translucent flexible linear body is erected on a substrate, or those formed in a loop, and those wound in a coil shape. These devices are transparent and semi-transparent, so it is difficult for birds to see them. By making them hooked, they were made aware of the danger and gradually aroused vigilance to stop them from approaching.

  Although the above-mentioned bird flying prevention device is considered to have a temporary effect, it uses a transparent, translucent linear body, so individuals without risk experience may fly without knowing it. There is a problem that the effect of preventing airborne flight is not recognized. In addition, even if there is some flying prevention effect even for individuals who do not have dangerous experience depending on the form of the device, a simple loop or line with a linear device can not evoke great alertness. It is thought that the effect of preventing flying will not last long as it gets used to it.

  Accordingly, an object of the present invention is not only to evoke a sense of vigilance due to the irregularity of the device, but also to give a great danger experience to birds that are approaching and contacting, and to be able to exert the flying prevention effect for a long time.

In order to solve the above-mentioned problem, the present invention fixes one end of a flexible linear body having a large number of required lengths to a part of an instrument body and freely extends from the fixed part to the other end. put out Shi because, the two pre-Symbol linear body to mutually nodule at the tip for each set as one set, birds flying preventing the formation of the circle of multiple variants by the linear body around the instrument body In the tool, the linear body is formed of synthetic resin as a material, half of which is colored yellow, and one of the two linear bodies is colored in yellow It is a thing.

  When the material itself has no wrinkles, the linear body freely extends and bends by its own weight, but when a coiling wrinkle or the like remains, it extends with a complicated curve and bends by its own weight. When such a linear body is knotted at the tip, a single ring is formed, but instead of a ring made of a single linear body, a ring is formed by knotting the tips of two linear bodies. Therefore, it is not a simple circular ring but an irregular ring. The size of the ring is set so that one leg of the crow can freely enter.

  A required number of such irregular rings are formed around the instrument body and move randomly under the influence of wind or the like, so that a strong sense of alertness is aroused to birds such as crows and their flight is prevented. Moreover, even if there is an individual who stops in the vicinity, the toenails or the like are easily tangled, so that a sense of alertness can be further evoked.

  By arranging and integrating the above-mentioned knots by arranging two linear bodies in the length direction, the two linear bodies are close to each other at the fixed end, but gradually spread toward the free end side. Since it bends in the middle or is bent by the heel of the material, and further becomes a collapsing shape at the knot portion at the tip, it becomes a deformed deformed ring.

Although it is difficult to explain the reason why the flying prevention effect is increased by using one of the two sets of two linear bodies colored in yellow , the yellow linear bodies are mixed. As a result of the experiment, the flying prevention effect was recognized as compared with the case of using the same color. Furthermore, it was also recognized that when the configuration in which the length of the free ends extending from the nodule portions of the two linear bodies had a difference was adopted, the flying prevention effect was higher than when the lengths were made uniform.

  In addition, if one linear body out of two linear bodies forming one ring is connected to another linear body through the other one ring, the deformity of one ring increases. In addition, the flying prevention effect can be increased.

As described above, the bird flying prevention device of the present invention is formed by forming a deformed ring by a set of two linear bodies and coloring one of the two sets of linear bodies in the yellow color. Because of the use of, the flying prevention effect can be enhanced by awakening the birds with great alertness due to the mixture of yellow linear bodies .

  Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1 (a), the bird flying prevention device of the embodiment is connected to the top of the instrument body 1 by attaching one end of a large number of synthetic resin (polycarbonate) linear bodies 2 to each other by welding, bonding or the like. And fix. The instrument body 1 has three columns 4 fixed on the upper surface of the substrate 3 in the middle, and the ones on both sides are fixed with an inclination angle, and a connecting bar 5 is integrally provided between the upper ends of these columns. (See Japanese Patent Laid-Open No. 9-322697). Although the height of the instrument main body 1 depends on the mounting location, it is about 10 cm to 20 cm, and the length of the linear body 2 is about 30 cm to 40 cm. The linear body 2 has a wire diameter of about 1 mm, is flexible, and some of the materials have coiling wrinkles remaining.

  The above-mentioned linear bodies 2 are arranged into a set of two, the leading end portions of each pair of linear bodies 2 are drawn together to form a knot 6 (see FIG. 2 (a)), and tied to the knot 6 through the end. Then, the nodule portion 7 is formed (see FIG. 2B). As shown in FIG. 2C, instead of the knot portion 7, the tip portions of the linear bodies 2 may be heated and melted to provide a welded portion 9 to be connected.

  A ring 8 is formed by the knot portion 7 or the welded portion 9 and the two linear bodies 2. Since the fixed portions of the linear bodies 2 are close to each other and the tips are aligned and knotted or welded, the ring 8 is not a simple circle but sharp at both ends. It becomes a deformed ring. A large number of such rings 8 are complicatedly overlapped around the instrument body 1 and exist.

Color linear member 2 is not limited to colorless, colored, using those colored in the mass of half yellow. In FIG. 1, a pair of two linear bodies 2 represented by a thick line represents a yellow linear body 2, and a thin line represents another colorless or colored one. These thick lines and thin lines indicate divisions for showing the difference in color, and do not mean that there is a difference in wire diameter. In each figure of FIG. 2, yellow coloring is represented by a halftone dot.

  As shown in each drawing of FIG. 2, it is desirable that the free end portion beyond the nodule portion 7 has a difference in length so that one linear body 2 extends long. It was confirmed that the flying prevention effect was higher than when the same length was used. This is considered to be because the deformability is further increased by extending one linear body 2 long.

  Moreover, when forming the said ring | wheel 8, as shown in FIG.1 (b), one linear body 2 of the two linear bodies 2 which form the one ring | wheel 8 is made into another one. You may make it connect with another one linear body 2 through the ring | wheel 8. FIG. If comprised in this way, wheel 8 will mutually be intertwined. Further, as shown in FIG. 1 (c), in addition to forming the nodule portion 7 'at the tip of the pair of two linear bodies 2, a nodule portion 7' is also formed at the intermediate portion thereof, Two rings 8 ′ and 8 ′ may be formed by the linear body 2.

  As described above, by making the rings 8 entangled with each other or by increasing the number of small rings 8 ′ provided with a knot portion 7 ′ in the middle part, the whole becomes complicated and the deformity increases.

  FIG. 3 shows a use state in which the bird flying prevention tool A is fixed to the arm 11 of the utility pole 10. As other applications, it can be installed in a part of the tower or attached to the ground line between the towers.
