Abstract

PROBLEM TO BE SOLVED: To prohibit birds from nesting on an electric pole and reduce short- circuit troubles in power lines by attaching an artificial bird tinted with a specific color to an electric wire-supporting arm of an electric pole. SOLUTION: An artificial bird 2 coated with a reflective color which birds hate (for example, yellow or white) is fixed to the top of a round rod made of a plastic 40-50cm long and 10mm in diameter and its bottom end is set to the supporting shaft of the bracket 4 and the bird set is detachably mounted to the arm supporting the electric lines of an electric pole. The round rod 3 is swung with winds and birds such as crows or storks do not come near and cannot build their nests.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is attached to an electric wire support arm of a utility pole to prevent birds from nesting, effectively reduce short circuit accidents of power transmission lines, and prevent nesting of a utility pole by birds. The present invention relates to a bird damage prevention device.

[0002]

2. Description of the Related Art Electric poles that support power transmission lines use materials mainly made of steel for supporting arms of electric wires in order to maintain structural strength. The insulator between the power transmission line and the support arm is provided by an insulator, which usually provides sufficient insulation performance. Transmission lines are generally erected high above the ground, providing a great resting place for birds, and it is common to see birds such as sparrows and crows stopped.

Further, birds such as crows and cormorants sometimes form nests between the insulators attached to the electric wire support arms of the electric poles. For these reasons, when a bird spreads its wings to fly away, the wings may touch an electric wire, a support arm, or the like to cause a short circuit, resulting in an overhead wire accident. In addition, it often causes fecal pollution in cityscapes. Such an accident is difficult to predict. Among them, Wuwu often makes nests on utility poles and picks up various things as nest materials, but there are also a lot of wires in them, which causes a short-circuit accident and sudden power failure. The inhabitants will be damaged.

In order to prevent these damages, a barbed body in which a needle-shaped puncture body is provided is attached to each part of the power transmission facility, or a light reflecting material is fixed to a pole / support arm of a utility pole, or There are things that make birds feel uncomfortable or anxious by infrared sensors. In addition, there are a bird nesting preventive device and method such as a device for applying a natural wind to emit a repellent odor of birds in multiple directions, and a method of applying a repellent material to a brace, a support arm or the like.

[0005]

The above-described conventional barbed body having a needle-shaped puncture body protrudingly attached to each part of the power transmission facility is not effective to some extent. However, it is thought that birds should avoid obstacles that are bird-like and stop. Further, the installation is required to be an installation that does not hinder the work on the pillar for maintenance and inspection of the power transmission line. Therefore, it is necessary to take measures against it.

As a method for fixing the light reflection, a mirror, a fine lens, a prism or the like made of a synthetic resin as a reflection material is used, but these have a directional restriction and at the same time become dirty. Less effective. It can be said that the thing using the infrared sensor is equivalent to the light reflection. There is also a method of intimidating sound or balloons, but birds also have a learning effect and become accustomed, and noise pollution and pollution caused by balloons also occur.

The bird nesting preventive device of the type which diffuses the odors repelling birds in multiple directions by utilizing the natural wind requires a complicated apparatus, is expensive, and requires a lot of labor for mounting. In addition, replacement of the aroma repellent is required when it is exhausted, and replacement of each electric pole requires enormous cost. The method of applying the repellent requires recoating. The present invention aims to provide a bird nesting prevention device that does not have the above problems.

[0008]

[Means for Solving the Problems] A pseudo-bird colored with a reflective color that birds dislike is 40 to 50 cm long and 10 mm in diameter.
Attach it to the tip of the plastic round bar and attach the rear end to the support shaft of the bracket and detachably attach it to the electric wire support arm of the utility pole.

[0009]

[Function] The pseudo bird is colored with a reflective color that birds dislike, and a model is attached to the tip of a long bar, so that the bar will sway due to the wind, so that crows and wreaths will approach. do not do.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below. First, as the pseudo bird (2), urethane foam is cast into a mold to be molded. A female screw for embedding a screw provided on the tip of a round bar (3) to which the pseudo bird (2) is attached is embedded in the abdomen of the pseudo bird (2) after the molding. Keep it.
The size of the pseudo bird (2) is formed to be approximately the same as or slightly larger than the size of the crow and the cormorant, and is colored with a reflective color.

The colors that birds dislike are yellow, white and blue. This is due to the habits of birds empirically grasped by a person in charge at a certain bird center (a bird garden that breeds various birds), and in this embodiment, most of them are pseudo birds (2). ) Was made, and the eyes and beak were colored as they were. As the reflective paint, commercially available synthetic resin enamel paint, trade name Hit Spray A Yellow (manufacturer: Campe) and other colors were used.

The round bar (3) to which the pseudo bird (2) is attached is made of plastic and has a diameter of 10 mm and lengths of 40 cm and 50 cm.
The M10 screws are applied to the two types of tips. Further, the bracket (4) for supporting the round bar (3) is also made of plastic. The body of the bracket (4) is U-shaped, and a cylindrical support shaft portion for supporting the round rod (3) is provided. After inserting the round rod (3) into the support shaft portion, the bracket (4) is fastened with a thumbscrew. The U-shaped body is formed so that it can be fitted into the support arm (11) of the electric wire (12) to manufacture the nesting prevention tool (1).

The bracket (4) of the nesting prevention tool (1) is attached to the support arm (11) for the electric wire (12) of the electric pole (10).
Insert it in and secure it with a butterfly screw. One or two nesting prevention tools (1) were attached to the electric pole (10). The nesting prevention tool (1) used in this implementation was molded using urethane foam and plastic, but this is to prevent a short circuit when it falls down, and is made of an insulating material. Other materials may be used as long as they are provided, or even conductive materials may be used as long as they are completely covered.

[0014]

As is apparent from the above description, the nesting prevention tool for a bird's utility pole of the present invention is used by attaching the nesting prevention tool to a support arm of an electric wire attached to a utility pole. Among the birds, Wuwu is particularly prone to the use of pseudo-birds that are colored with a color that they hate to reflect. Furthermore, by attaching a pseudo bird to the end of a long and narrow round bar, the pseudo bird seems to stop still when there is no wind, and it seems to be threatening to lean against it because it shakes when there is some wind. I can't stop by. Therefore,
I can't nest.

Although the conventional methods and devices have been effective as such, they hinder work during maintenance and inspection, and the device becomes large and large, which causes problems in manufacturing cost and installation on a utility pole. is there. The nesting prevention tool of the present invention has a simple structure, can be manufactured at low cost, and can be easily attached and maintained later.
