2. Description of the Related Art Conventionally, damage caused by bird nesting has occurred in various places. For example, utility poles for high-voltage lines are high and have a good view, and because people cannot approach them, they are a suitable nesting place for crows, etc. The vicinity of the intersection is suitable for nesting, and there are many short-circuiting accidents where crows nest in here and the conductive material contained in the nest material touches the charging part.

There are various kinds of devices or methods proposed by electric power companies or the like for preventing damage of this kind, but they are generally classified as follows.

(1) Place an object with a special appearance,
A method of stimulating the five senses of a bird by making a special sound or smell and keeping the bird away from the damaged area.

(2) A method in which a large number of catch boxes are installed in the vicinity of the damaged area to catch the birds live.

(3) A method of shooting and killing with a gun or poisoning with a poison.

[0007]

However, the above-mentioned conventional techniques either cannot maintain a sufficient effect or have other problems even if they have an effect.
That is, in the method (1), the effect is temporary, and after the bird becomes accustomed to the object or the like, the effect disappears thereafter.
The method (2) is effective, but it is difficult to install a large number of catch boxes, especially in an urban area, and it is costly to implement. Further, the method (3) cannot be implemented in an urban area or the like due to the limitation of the place where the gun is used.

The present invention has been made by paying attention to the problems of the prior art, and has a simple structure, is easy to install, and can be used in urban areas without any problems, thus making a bird's nest. It is intended to provide a bird damage preventive device that can prevent

The mounting member 40 is a ring-shaped portion 41 mounted on the telephone pole 1 and fixed at a predetermined height by screwing or the like.
And a frame portion 42 formed to extend laterally from the ring-shaped portion 41. The ring-shaped portion 4
As shown in FIG. 2, 1 is divided into two parts, and the two parts are fixed by bolts on both sides so that the electric pole 1 is sandwiched between the two parts.

As shown in FIGS. 4 and 5, the wind turbine 10 has a hollow shaft portion rotatably attached to the outer circumference of a support shaft 43 provided upright at the tip of the frame portion 42 of the attachment member 40 by bearings 44 and 45. 11 and four rod-shaped portions 12 extending in four directions from four locations at equal intervals on the outer circumference of the hollow shaft portion 11.
And a cup-shaped portion 13 attached to the tip of the rod-shaped portion 12, respectively. In this case, the cup-shaped portion 13
Is the blade that receives the wind.

The fixture 50 comprises a U-shaped portion 51 fitted in the crossbar 2, and a cylindrical portion 52 for shaft support provided upright on the upper surface of the U-shaped portion 51, and fixed to a predetermined position of the crossbar 2 by a bolt 53 screwed to the lower portion. It is what is done.

In this case, the impeller 20 has four blades and is attached to the tip of the impeller shaft 21. With the impeller shaft 21 inserted in the cylindrical portion 52 at the base end side,
The bearings 22 and 23 are supported, and the tip thereof is the impeller 2
Transmission mechanism 3 which will be described later and extends upward through the boss portion 0
I / O boss 3 on one side of flexible tube 37
7b and is fixed to the input / output boss portion 37b by a screw screwed in from the radial direction.

The transmission mechanism 30 includes a hollow shaft portion 11 of the wind turbine 10.
A small gear 31 fixed to the outer periphery of the small gear, and two large gears 32 arranged on both sides of the small gear 31 in mesh with each other,
Transmission shafts 33 fixed on the lower axis of the large gears 32, bearings 34 and 35 for rotatably supporting the transmission shafts 33 and the large gears 32 with respect to the frame portion 42, and a frame portion 42, respectively. The input / output boss 37a on one end side is attached to the lower end of the transmission shaft 33 protruding downward, and the input / output boss 3 on the other end side is attached to the tip of the impeller shaft 21.
7b is attached to the flexible shaft 37. The lower end of the transmission shaft 33 is also fixed to the input / output boss portion 37a on one end side of the flexible tube 37 by a screw screwed into the input / output boss portion 37a from the radial direction.

Here, the bearings 34 and 35 are mounted in cylindrical portions 46 and 46 which are erected side by side on both sides of the hollow shaft portion 11 on the upper end surface of the frame portion 42. The transmission shaft 33 is inserted into the portion 46 in a penetrating state. Further, in this case, the flexible shaft 37 includes a flexible tube 37c,
The flexible shaft body 37d having flexibility and rotatably supported in the tube 37c, and the input / output boss portions 37a and 37b connected to both ends of the flexible shaft body 37d, respectively.

As the flexible shaft 37, a commercially available one (for example, product name; flex shaft, maker; Akiwa Seijo Seisakusho Co., Ltd.) can be used. Also, this flexible shaft 3
As for 7, it is not always necessary to use the one having the tube 37c, and if there is no need to protect the rotating portion from the outside, a type without the tube 37c can be used. Further, even when a certain type of tube 37c is used, the rotation of the tube 37c is not particularly restricted as described above (the tube 37c is simply attached around the flexible shaft 37 main body 37d).
Not limited to this, when there is an object that comes into contact with the flexible shaft 37, the tube 37c may not rotate reliably in order to reliably prevent sliding contact with the object. In this case, for example, a cylindrical portion extending concentrically from the lower surface of the distal end of the frame portion 42 so as to cover the outer periphery of the transmission shaft 33 is provided, and the end portion of the tube 37c is fitted into the distal end of the cylindrical portion. It may be fixed.

A cover plate 60 is attached to the above device so as to protect the small gear 31 and the large gear 32 between the rod-shaped portion 12 and the small gear 31 on the outer periphery of the hollow shaft 11. However, this is not always a necessary configuration.

Next, the operation will be described. First, the device
The mounting member 40 can be easily installed on the utility pole 1 simply by mounting the mounting member 40 at a suitable height of the utility pole 1 and the fixture 50 of the impeller 20 at a suitable position of the crossbar 2 and tightening the respective bolts. The flexible shaft 37 absorbs the positional and directional deviation between the wind turbine 10 and the impeller 20 at that time.

When the wind turbine 10 receives wind and rotates, this rotation is decelerated and transmitted to each transmission shaft 33 as the small gear 31 and the large gear 32 rotate while meshing with each other. And this rotation is flexible shaft 3
7 is transmitted to the impeller 20 and the impeller 20 makes the windmill 10
It rotates at a lower speed and higher torque than the rotation of. For this reason,
On a day when the wind blows, crows cannot nest in the position where the impeller 20 is attached (in this case, the crossbar 2 and the utility pole 1 intersect). Also, when the wind has completely stopped,
Even if the crows start building nests, the impeller 20 rotates when the wind blows, so that the nests are pushed away by the impeller 20. At this time, the fact that the rotation of the impeller 20 is decelerated to a high torque ensures this action.

That is, the above-mentioned device has a simple structure in which the impeller is rotated to prevent nest formation, and the structure is simple and does not require energy such as electric power. It is possible to semipermanently prevent the nesting of a bird at a predetermined position on the electric pole 1. Moreover, the windmill 10
The flexible shaft 3 is used to transmit rotation between the blade and the impeller 20.
Since 7 is used, if it is easy to install and is within the range of the offset allowable value of the flexible shaft 37, the nesting is prevented while maintaining the position of the wind turbine 10 at a position suitable for receiving the wind. Position to try (impeller 20
It is possible at any time to change or adjust only the position). For example, it is possible to attach and change the impeller 20 to the crossbar 3. Therefore, it is possible to surely position the impeller at the position where the crows make nests and prevent the damage of the nests of the crows easily and reliably even in urban areas.

In the above embodiment, an example of the present invention in which the utility pole 1 is attached to the utility pole 1 is shown. However, only the utility pole 1 can be obtained by adapting the shape of the mounting member 40 or the fixture 50 to a building to which the shape is attached. It goes without saying that the present invention can be applied to houses and various other structures. Also,
If necessary, a plurality of impellers can be provided.

[0027]

[Effects of the Invention] According to the bird damage preventer of the present invention, the impeller is rotated to prevent nest formation, and the structure is harmless and simple, and does not require energy such as electric power. However, it is possible to semi-permanently prevent the nesting of birds at predetermined positions in the building. Moreover,
A flexible shaft is used to transmit the rotation between the wind turbine and the impeller, so it is easy to install and the position where the nesting is to be prevented while maintaining the position of the wind turbine suitable for receiving the wind. It is possible at any time to change or adjust only.

Since the wind turbine and the impeller are supported by a mounting member or a fixture that can be attached to and detached from the building, the installation is easy, and the position or position of the wind turbine or the impeller after the device is installed is adjusted. The change is extremely easy. Therefore, by positioning the impeller at an appropriate position where the crows make their nests, the nesting of the crows can be prevented easily and surely without any problems even in urban areas. It becomes possible.
