[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The invention relates primarily to devices that prevent birds from nesting on power transmission towers.

[0002]

[Prior art]

 Birds such as crows and cormorants often form nests on power transmission towers, and wire is sometimes used as a material for such nests. This can cause short-circuiting of power lines, disconnection of power lines, and power outages. This power outage and other accidents are thought to be one of the causes of adverse effects on computers and other control equipment. Various devices have been published or implemented to prevent these harmful birds from forming nests on power transmission towers.

Conventionally, there are various kinds of instruments of this kind, such as weather vanes, windmills with permanent magnets attached thereto, and multi-circular plates or balloons. If a bird is approaching using a weather bird type sensor and a harmful bird approaches, it is expensive to use threats such as voices, and it is necessary to use a large number of steel bars with long horizontal bars. It is effective but has some drawbacks in life. The multi-circle board is difficult to use as a rocking type because it receives the wind pressure of the wind at a high tower, and the fixed type does not maintain the effect because the birds get used to it quickly. Balloon types cannot withstand long-term use.

[0004]

[Problems to be solved by the invention]

 Therefore, this invention has a simple structure, can withstand long-term use, can be used with a small length of steel bar, and does not diminish the bird protection effect for a long period of time. The aim is to provide the market with bird-proofing equipment that does not require power transmission and reduce the occurrence of power transmission accidents.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned task, this invention is to develop a leaf spring or bar spring that rises vertically from the upper surface of a clamp member attached to a horizontal bar where birds may stop, in some facilities where birds need to be prevented. The leaf spring or the bar spring is provided with a bird-preventing tool in which a bird chase bar made of a material that can be easily cut can be attached in a direction substantially parallel to the horizontal bar. .

In order to achieve the above-mentioned object, at least two clamp members provided with the leaf springs or the rod springs of the bird harm prevention device of the present invention are provided for one bird chase rod.

A nut 16 such as a spring washer 18 is interposed between the fastening bolt 15 and the nut 16 of the nut 16.

A common single long bolt 20 passes through the distal end portion 18 of the jaws 13a and 13b, and is tightened by a second nut 21. The pair of long bolts 20 penetrate the pair of jaws 13a and 13b. Each of the bolt through holes 22 provided in the long pieces 13a of the L-shaped plates 11 and 12 is formed as a long hole in the longitudinal direction, and can correspond to the thickness of the steel frame used. The second nut 21 is also provided with a spring washer 18 for preventing loosening.

A root of a leaf spring 23, which is an example of a leaf spring or a bar spring, is fixed vertically to an intermediate portion of the long piece 13a of one of the pair of L-shaped plates 11, 12. It is fixed via a small L-shaped fixing member 24 in the figure. The length of the leaf spring 23 is set to 10 to 15 cm, but is not limited to this length. The strength of the leaf spring 23 is set to such a degree that the crow, cormorant or the like easily bends by 30 ° to 180 ° when it stops on the bird-tracking rod 26. A small hole 25 is provided at the tip of the leaf spring in the width direction of the pair of L-shaped plates 11 and 12. The leaf spring 23 is exemplified by a leaf spring usually made of a material such as phosphor bronze, but it may be a single thin piano wire, a rod-shaped coil spring, or a weather-resistant plastic leaf spring. In this specification, the concept of a leaf spring or a bar spring is included.

Reference numeral 26 denotes a bird-thinning bar inserted into the small hole 25, which is preferably about 2 to 5 mm in thickness, usually an aluminum bar, but a hard to semi-hard synthetic resin bar or the like within a uniform range in the present invention. is there.
