Description

  The present invention relates to a fixed bird protection seal that repels birds from an article by adhesion to the article, and in particular threatens birds by stably generating sufficient emission light without depending on the position of the birds. An object of the present invention is to provide a fixed bird protection seal that exhibits a high repellent effect in consideration of light coloration and visual characteristics of birds.

  The damage caused by power outages caused by birds, such as crows, nesting on power poles, has occurred a great deal throughout the year, annoying those skilled in the art. In order to solve the problem, a means of removing the nest is taken, but since a new nest is created again by these birds, it is not a fundamental problem solution.

In order to solve this problem, the background art forms a hologram sheet on which a pattern based on an arbitrary pattern is formed along a cylindrical surface or a conical curved surface, and uses light reflection surfaces on the front and back of the hologram sheet. Some repel birds (see, for example, Patent Document 1). In addition, a repellent member using the visual effect of the hue change according to the incident angle of light due to the multilayer film structure of the light interference pigment, and the visual effect of the rainbow spectrum appearance change due to the microstructure surface of the light diffraction pigment were used. Some repel birds using at least one of the repellent members (see, for example, Patent Document 2).

Explanatory drawing which shows the example of a pattern of a shield is shown.

  In FIG. 4, the fixed bird guard 1 according to the present embodiment is configured to include the pattern portion 11 and the injection portion 12 as in the first embodiment. In the present embodiment, the injection unit 12 has a configuration in which an upper injection unit 12a and a lower injection unit 12b are stacked. Each of the upper injection part 12a and the lower injection part 12b has a fixed emission angle.

Hereinafter, the content changed from the said 1st Embodiment about the repelling operation | movement of the fixed bird guard seal of this embodiment based on the said structure is demonstrated.
First, as shown in FIG. 4, the fixed birdcage seal 1 emits natural light by the emitting part 12 formed from the upper emitting part 12a and the lower emitting part 12b as diffraction gratings each having a constant diffraction constant. Diffraction. The injection unit 12, in the figure, the upper injection unit 12a is diffracted at the diffraction angle theta ₃ against natural light e emitted diffracted light f, the lower exit portion 12b is the diffraction angle theta with respect to natural light g Diffracted at ₄ and diffracted light h is emitted.

  As shown in FIG. 5A, the upper emission part 12a and the lower emission part 12b are formed of diffraction gratings, and generate interference fringes having different diffraction angles. As shown in FIG. 5B, the upper injection portion 12a and the lower injection portion 12b are characterized in that a new striped pattern is formed as a moire pattern in the laminated portion as shown in FIG.

As shown in FIG. 2C, the emission portion 12 is formed by laminating the upper emission portion 12a and the lower emission portion 12b, so that moire pattern interference fringes are formed over the entire emission portion 12. Thus, the three-dimensional moire pattern of the emitted light captures the birds and can strongly threaten the birds. Further, as shown in FIG. 6, the emitting section 12 includes an upper emitting section 12 a that emits diffracted light j with natural light i at a reflection angle θ ₅ and a reflection angle at which natural light k is emitted with diffracted light l at a reflection angle θ _6. By forming the lower emission portion 12b having θ ₆ by laminating, it is possible to easily emit the emission light having the moire pattern.

  Moreover, although the fixed bird guard seal 1 which concerns on the above-mentioned embodiment made the pupil part 11a of an eyeball pattern black without a pattern, as shown in FIG. 7, a mesh pattern is the center part or the whole of this pupil part 11a. It may be added to the part. The fixed bird protection seal 1 creates a three-dimensional effect on the eyeball pattern due to the mesh pattern, which makes it easier for birds to have an illusion of the eyeball pattern of a bird of prey, thereby increasing the repelling effect.

  Moreover, although the said iris part 11b was made into the yellow color scheme, it can also be made brown. This fixed bird protection seal 1 recognizes the iris portion 11b with emphasis on the birds from the characteristics of the oil ball that controls the visual recognition of the birds in both cases of yellow and brown. Probability can be increased. For example, by sticking on the upper surface, the detection probability from birds flying in the sky can be further increased.

  The fixed bird guard 1 according to the above-described embodiment is applied by being fixed to the utility pole head 101 of the utility pole 100, but is not limited to this application method, and is installed near the utility pole head 101, for example. It can also be fixed to a utility pole arm, and can be widely applied to repel birds, such as attics where birds tend to nest and cars in parking lots where birds tend to drop dung.
