Description

[Detailed description of the invention] Industrial application field This invention prevents flashover accidents caused by large birds such as crows and black kites flying into outdoor steel structures of power generation and substations, supports of power transmission lines, etc. This product relates to a bird damage prevention device that is used to protect plant buds and fruits from damage caused by birds, and to protect shrines, temples, etc. from damage caused by pigeon droppings. It was designed to prevent this.

Conventional technology Visual bird damage prevention devices include (1) devices that use a light reflecting plate, (2) devices that use a light emitting device such as a searchlight or flash, and (3) devices that use a light emitting device such as a searchlight or flashlight. A method using a model is known. Among these, bird damage preventers using light reflectors are widely used.

Problems that the invention aims to solve By the way, conventional bird damage deterrents using light reflectors were generally just "stainless steel plates cut into rectangular shapes and attached to them with fasteners such as wire or string." The following problems arose.

(1) It is not effective enough because it simply threatens birds by reflecting light.

(2) Difficult to securely and firmly attach to power transmission towers, etc.

This invention was devised with the aim of solving the above-mentioned conventional problems, and has a shape and swing pattern made to resemble the eyes of natural enemies such as owl-eagles and eagle-hawks, in addition to the bird damage prevention effect based on the reflection of light. , in addition to the bird damage prevention effect based on color, the reflection of light, shape, vibration,
The synergistic effect of the colors dramatically improves the bird damage prevention effect, improves durability, and makes it easy to attach and detach from the angle steel of the power transmission tower.

Means for Solving the Problems A light reflecting plate formed in an eyeball shape, a cylindrical light reflecting plate support that swingably supports the light reflecting plate on an outer peripheral surface colored black and yellow, The light reflecting plate support was constructed with a clamp fitting to be attached to an angle steel member of a power transmission tower.

Effect: Not only does the reflected light prevent damage to birds, but also the eye shape and yellow color, which are made to resemble the eyes of natural enemies such as owls and eagle hawks, prevent bird damage (birds instinctively dislike the eye shape and yellow color). Furthermore, the synergistic effect of the eyeball's swing (reflecting light in different directions) dramatically improves the bird damage prevention effect (proven through various experiments), and the clamp fittings also allow for the installation and removal of steel towers from angle-shaped steel, etc. can improve workability.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

Reference numeral 1 indicates three light reflecting plates formed in an eyeball shape (round shape), and 2 indicates a cylindrical light reflecting plate support that swingably supports the light reflecting plate 1 on an outer peripheral surface colored in yellow. , 3 are clamp fittings for attaching the light reflecting plate support 2 to an angle steel member of a power transmission tower.

The light reflector 1 is formed of stainless steel or other stainless steel into a so-called round dish shape (resembling the eye of a natural enemy), and is swung to the light reflector support 2 by a bolt 4 installed in the center. It is designed to be movably mounted.

The light reflecting plate support 2 is formed of metal or plastic into a cylindrical shape. Three bolt receiving holes 5...5 are formed at intervals of 120 degrees on the circumferential surface, and the bolts 4 installed in the light reflecting plate 1 are loosely fitted into these bolt receiving holes 5...5, respectively. As a result, the three light reflecting plates 1...1 are supported so as to be able to swing in 120° increments, and their outer peripheral surfaces are colored yellow.
The peripheral edge portions 2a...2a of the parts where the parts are attached are colored black. This is to make the light reflecting plates 1...1 more noticeable. Reference numeral 6 indicates a leg piece for attaching a clamp fitting, and the lower end of the leg piece 6 is attached to the light reflecting plate support 2.
The light reflecting plate support 2 is fixed to the inner circumferential surface side of the light reflecting plate support 2 while protruding from the lower edge thereof.

The clamp fitting 3 is attached to the leg piece 6 by leg fixing bolts, nuts 7 and 8, and angle adjustment bolts and nuts 9 and 10, and the clamp fitting 3 is attached to the leg piece 6 into which the angle adjustment bolt 9 is inserted. An L-shaped base plate 12 whose angle can be adjusted within the range of an arc-shaped bolt receiving hole 6a provided, and the base plate 12
A bolt rod 13 planted in the center of the bottom surface 12a of
, a movable hook 14 slidably fitted to the bolt rod 13 , and a tightening nut 15 screwed to the bolt rod 14 . By sandwiching the angle steel members 16 of the power transmission tower between the movable hook 14 and tightening them with the tightening nuts 15, the angle steel members 1 of the power transmission tower are tightened.
It is designed to be fixed to 6.

Reference numerals 17 and 18 denote a stopper and a hanger. These stopper 17 and hanger 18 are formed by joining the back sides of L-shaped metal fittings, and a collar 19 and a collar 19 are attached to the tip of the bolt 4 installed in the light reflecting plate 1. It is attached in a state where it is clamped between nuts 20. The tip 17a of the stopper 17 comes into contact with the inner peripheral surface of the light reflecting plate support 2 to prevent the bolt 4 from coming off the bolt receiving hole 5, and the stopper 17 and the light reflecting plate 1
The light reflecting plate 1 is oscillated within a range of an interval d.

Reference numeral 21 denotes a wind baffle plate suspended from the hanger 18 via a connecting device 22 such as a chain. It protrudes from the lower end of the support body 2 and receives the wind in the outside air, swings itself and shines, and also swings the eyeball-shaped light reflecting plate to reflect it in a different direction. It is designed to shine brightly.

Since the bird damage prevention device of the embodiment has the above-described configuration, by using the clamp fitting 3, it can be easily attached to the angle-shaped steel member 16 of a steel tower, etc. When the wind receiving plate 21 and the light reflecting plate 1 receive the light, they not only reflect the light diffusely and pose a threat to birds, but also cause the light reflecting plate 1 to swing.
The shape and color of the outer peripheral surface of the light reflecting plate support 2 (yellow)
However, since it poses a threat to birds, the synergistic effect of these methods dramatically improves the bird damage prevention effect compared to conventional methods.

In the embodiment shown in the drawings, a rectangular wind baffle 21 is used.
Although the case in which the light reflecting plate 1 is oscillated is shown in , any means for oscillating the light reflecting plate 1 may be used.

Effects of the Invention As explained above, the present invention includes a light reflecting plate 1 formed in the shape of an eyeball made to resemble the eyes of natural enemies such as owls and eagle hawks, and the light reflecting plate 1 being colored black and yellow. A bird damage preventer is constructed of a cylindrical light reflecting plate support 2 swingably supported on the outer circumferential surface and a clamp fitting 3 for attaching the light reflecting plate support 2 to an angle steel member of a power transmission tower, etc. Therefore, it has the following effects.

(1) Not only the reflection of light by the light reflection plate 1, but also the shape of the light reflection plate 1 (the shape of a natural enemy's eyeball), the swinging (reflection in a different direction), and the color of the outer peripheral surface of the light reflection plate support 2 ( (yellow) can also pose a threat to birds, and their synergistic effect can dramatically improve the bird damage prevention effect.

(2) The clamp fitting 3 allows the power transmission tower to be easily attached to and detached from angle steel, etc.
