Description

[Detailed description of the invention] (Field of industrial application) This invention is a bird damage prevention device applied to prevent the flying of starlings, sparrows, crows, etc. that fly in groups and cause fecal damage to steel towers, electric wires, orchards, etc. It is related to.

(Prior art) Conventionally, in order to prevent fecal damage caused by birds flying en masse to the steel tower, there has been a method of attaching needle-like protruding metal fittings to armrests, etc., or applying bird repellent to the required parts of the steel tower. For example, there is a means to hang a display tag called a hawk's eye (see Japanese Utility Model Application Publication No. 168382/1982). These measures have the effect of preventing nesting, but their effect on preventing birds from flying away is extremely poor.

Therefore, a means for installing a vibrating mirror to prevent birds from flying in (see Utility Model Application No. 60-77388),
There is a means for attaching a plurality of reflecting mirrors to a flying body-like member (see Japanese Utility Model Application Publication No. 186378/1983).

Measures using such vibrating mirrors and reflective mirrors are inappropriate for preventing bird damage on steel towers exposed to wind and rain, and are easily destroyed by collisions with the tower parts due to strong winds. Because of this, there were drawbacks such as the birds eventually getting used to it and losing its repelling effect.

(Problems that the invention aims to solve) Bird damage prevention devices that use reflective mirrors are not suitable for application to steel towers, and there is little change even if they are disturbed by surface light reflection, and birds may become accustomed to them and be chased away. There were problems in that not only did it lose its effectiveness, but it also lacked the effect of preventing flying objects.

(Means for solving the problem) This invention always makes birds wary by changing the reflection of light depending on the sunlight irradiation condition, three-dimensional light reflection, and the appearance and hiding of reflected light depending on the flying angle of the bird. It is designed to prevent people from getting close to people and prevent fecal contamination or damage to crops etc. due to mass flying, and has a central vertical partition wall on the back side.
A serrated portion is provided at intervals on both sides of the central vertical partition wall, extends vertically along the central vertical partition wall, and has a serrated side surface. A transparent or translucent synthetic resin body is provided with a gap-forming surface portion that can define a gap between the reflective wall portion and the back surface of the synthetic resin body is plated with silver or the like. , a reflective part consisting of a reflective sawtooth part and a reflective surface part is formed to form a reflector, and a hook plate with a bent end at the upper part and a plurality of through holes at the lower part, and a ring member can be freely rotated in the horizontal direction. A bird damage prevention device comprising: a hanging member consisting of a plurality of ring members including connected hanging fittings; and the back side of the reflector is fixed to a mounting plate, and the integral body is attached to the hanging member. It is a ingredient.

(Function) The light rays that have passed through the transparent or semi-transparent synthetic resin body hit the reflective serrated portion of the reflective part and are highlighted, and the free movement of the suspension member causes the reflective serrated portion to become uneven and horizontally parallel. It can be seen through as a geometric pattern formed by straight lines and obliquely parallel lines, and prevents birds from flying in. It also has a directional reflective ability depending on the angle of the bird's flight to the reflector and the sun's rays to blind the birds and prevent them from flying in. I can do it.

(Embodiment) To explain an embodiment of the present invention with reference to FIGS. 1 to 4, a bird damage prevention device 1 includes a main body 2 made of synthetic resin that is transparent or semi-transparent in yellow, white, etc. A reflector 4 consisting of a reflector 3 formed on the back surface of a body 2 is attached to a freely movable hanging member 5.

The synthetic resin main body 2 has a front surface 6 with a vertical central ridgeline portion 7 and sloped portions 8, 8 on both sides of the vertical central ridgeline portion 7.
A central vertical partition wall 10 is formed on the back surface 9, and serrations are provided at intervals on both sides of the central vertical partition wall 10 and extend vertically along the central vertical partition wall 10. 11, 11 and a gap forming surface portion 12 are formed.

Here, the serrated portion 11 has a serrated surface 11a on its side surface, and the gap forming surface portion 12 is formed so that a gap is defined between the reflector 4 and the mounting plate 16 when the reflector 4 is fixed to the mounting plate 16. It is set as.

Silver plating or the like is applied to the back surface 9 including the sawtooth part 11, the central vertical partition wall part 10, and the gap forming surface part 12, so that the reflective sawtooth part 13, the reflective wall part 14,
A reflector 4 is formed by forming a reflective portion 3 as a reflective surface portion 15.
A mounting plate 16 made of a transparent synthetic resin is fixed to the back surface 9 of the reflector 4 by adhesive or the like to form an integral body.

The suspension member 5 has an upper portion having a bent end portion 17a,
It consists of a hook plate 17 with a plurality of through holes 17b, 17b... provided at its lower part, and ring members 18, 19, 20, 21, and the ring members 19, 20 are connected by a pin 22 so as to be freely rotatable in the horizontal direction. A certain hanging fitting 2
The ring member 18 at the upper end of 3 is formed to pass through the through hole 17b.

In this case, the through hole 16 provided at the upper end of the mounting plate 16
Pass the ring member 21 through the reflector 4 and the mounting plate 16
A hanging fitting 24 similar to the above-mentioned hanging fitting 23 is passed through a through hole 16b at the lower end of the mounting plate 16. It is possible to install the required number of units in the vertical direction.

The bird damage prevention device 1 of the present invention is constructed as described above and is installed as follows.

That is, when installing it on a steel tower A as shown in FIGS. 5 and 6, the bent end 17a of the hook plate 17 is hooked onto the vertical part C of the angle part B of the steel tower A.
Hook the hook bolt to the horizontal part E of the angle part B, insert it through the through hole 17a of the hook plate 17, and tighten and fix it to the washer via the nut.

In this way, if the bird damage preventive devices 1, 1, etc. are attached to desired locations such as the arms of the steel tower A, then when the reflector 4 is irradiated with sunlight, the reflective serrated portion 13 , the reflective wall portion 14 and the reflective surface portion 15. In particular, in the reflective serrated portion 13, the serrated surface 11a reflects the sunlight with good directional reflection performance, allowing it to be reflected even from a long distance. The reflective portion 3, particularly the reflective serrated portion 13, is visible in an embossed manner from the synthetic resin main body 2.

Also, depending on the angle at which the bird flies, the irradiation state of the sunlight, and the movement of the freely movable hanging member 5, the silver color,
The reflected rays, such as golden yellow, suddenly shine, and the reflected rays enter the eyes of the birds, causing them to become wary and unable to fly away.

(Effects of the invention) The bird damage prevention device of the invention has a transparent or translucent synthetic resin main body with silver plating applied to the back side to form a reflective part consisting of a reflective sawtooth part, a reflective wall part, and a reflective surface part. Because it is made into a reflector, the sunlight that passes through the transparent or translucent synthetic resin body hits the reflective part, and the reflective part, especially the reflective sawtooth part, becomes embossed, making it visible even from a long distance. This can prevent birds from flying into the area.

In addition, since the reflector is attached to the suspension member that allows the ring member to freely rotate in the horizontal direction, the reflected light such as silver will suddenly change depending on the angle at which the bird flies, the irradiation state of the sun's rays, and the movement of the suspension member. It shines brightly and blinds birds, making them wary and preventing them from approaching.

Therefore, it exhibits practical effects such as being able to prevent fecal contamination and damage to agricultural crops due to flying birds.

In addition, since the bird damage prevention device of the present invention is made of a synthetic resin main body, it will not be easily destroyed by collisions and has excellent durability even if it is installed on a steel tower etc. that is exposed to rain and wind. .
