Description

  The present invention relates to a bird damage prevention device, and more particularly to a bird damage prevention device attached to a structure.

  In recent years, due to the cutting of mountain forests and the progress of urban development, birds have stopped on high-rise structures such as overhead transmission and distribution lines, transmission towers, power poles and other power transmission facilities, and handrails on verandas of high-rise apartments. There are many things to do. When birds stop at these high-rise structures, fecal damage may occur, or noise from squealing may occur. In particular, when birds nest in a power transmission / distribution facility, the material for nesting may fall, and the dropped material may come into contact with an aerial transmission / distribution line, causing a ground fault or a short-circuit accident. Accordingly, various techniques for preventing the occurrence of bird damage by suppressing the birds from stopping in the structure or nesting have been proposed.

  Patent Document 1 discloses a bird flying prevention mat that prevents birds from stopping on various structures. This bird flying prevention mat is provided with a rug-like base mounted on a structure, and is formed by laminating sponge materials on the upper surface of the base. A resin support member is formed on the upper surface of the base member, and a return portion is formed on the support member so as to be folded back from the top portion toward the base member. When birds try to land on the bird flying prevention mat, since the return portion of the support member is formed downward from the top, the bird's feet land on the base body without being inhibited by the return portion. On the other hand, when the birds try to take off their legs to take off, their legs get caught on the return part, making it difficult to pull out and making it difficult to take off.

  For this reason, birds who have once landed on this bird flying prevention mat will recognize from experience that it will be difficult to pull out their feet, so avoid landing on a structure equipped with a bird flying prevention mat. become. In addition, other birds that have not landed on a structure equipped with a bird flying prevention mat should also be judged based on the situation where birds landing on a structure equipped with a bird flying prevention mat have avoided landing. To avoid landing. Therefore, bird damage is prevented in the structure on which the bird flying prevention mat is mounted.

  Such a bird flying prevention mat is attached to a structure using a binding member such as a band-like band, for example.

Japanese Patent Laid-Open No. 08-228656

  In addition, when the base is attached to the overhead transmission / distribution facility, the overhead transmission / distribution facility is covered and cannot be visually recognized from the outside. Therefore, as long as the bird flying prevention mat is installed, it is not possible to visually check the status of the overhead transmission / distribution facility, and the bird flying prevention mat is intentionally removed from the overhead transmission / distribution facility for status confirmation. Necessary and complicated work occurs. As a result, there may be a delay in the discovery of defects such as corrosion and failure occurring in the equipment.

  Furthermore, the bird flying prevention mat must be attached to the structure using a binding member or the like formed separately from the bird flying prevention mat after the bird flying prevention mat is wrapped around the structure. The mounting work becomes complicated. In particular, when a bird flying prevention mat is installed in a relatively high place such as an aerial transmission / distribution facility, the bird flying prevention mat is attached in combination with a plurality of separate binding members at a high place. For this reason, a great deal of work difficulty is associated with mounting. On the other hand, when removing the attached birds flying prevention mat, the same problem as in the case of mounting will occur.
