Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing bird damage, which prevents bird nesting, fouling of buildings and the like by feces, and electrical failure in power transmission and distribution equipment.

[0002]

2. Description of the Related Art Various means have been proposed for repelling birds. For example, there are a needle-like projection, a magnet-attached strip, a balloon imitating an eyeball, and the like, each of which has a certain effect.

[0003]

However, birds that cause bird harm, such as pigeons, rakutori, and crows, have a high learning ability, and even if they are effective temporarily, they become accustomed to them in a short period of time, resulting in a long-term repellent effect. Difficult to maintain. Needle-like projections are effective in terms of long-term repellent effects, but may damage birds and people who handle these projections. Therefore, a main object of the present invention is to provide a bird harm prevention device which does not damage birds or humans and can expect a bird repelling effect for a long term.

[0004]

SUMMARY OF THE INVENTION The present invention achieves the above object, and is characterized by a guide rail, a traveling machine traveling along the guide rail, and a threatening body attached to the traveling machine. To be equipped.

The material and configuration of the guide rail are not particularly limited as long as the guide rail has a strength that does not hinder the traveling of the traveling machine. For example, in addition to a rigid rail, a flexible material such as a wire can be used. Examples of the rigid rail include application of a rail for a fall prevention device attached to a steel tower. The guide rail preferably has a structure in which a feeder line for supplying power to the traveling machine is provided, and is configured to be attached to an angle member of a steel tower or the like using a mounting bracket. It is optimal to provide a hangar for accommodating the traveling machine and the threatening body on such a rail. The threatening body protrudes from the hangar only when traveling, and is stored in the hangar during suspension. The hangar preferably has a structure that is not easily affected by wind.

[0006] The traveling machine preferably has a sprocket meshing with the guide rail and a drive mechanism for rotating the sprocket. In particular, it is desirable that the traveling machine includes a random signal generating means for irregularly controlling the traveling speed and a timer means for regulating the traveling time.

The threatening body is preferably a natural enemy for birds to be repelled, for example, a model of a bird of prey. It is also desirable to have a luminous body in the eye of the raptor model. Further, it is appropriate to attach such a threatening body to a traveling machine so as to rotate in accordance with the wind direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below, taking as an example the case where the apparatus of the present invention is mounted on a steel tower.
FIG. 1 shows a state in which the apparatus of the present invention is mounted on the top of a steel tower, where (A) is a plan view and (B) is a side view. FIG. 2 is a front view of the traveling machine and the threatening body, and FIG. 3 is a side view of the same. 4A and 4B show rail mounting brackets, wherein FIG. 4A is a plan view and FIG. 4B is a side view.

As shown in FIG. 1, the apparatus according to the present invention
The vehicle includes a circular guide rail 1 mounted with mounting brackets 4, a traveling machine 2 traveling along the guide rail 1, and a threatening body 3 attached to the traveling machine 2. The threatening body 3 is of a form that repels birds, and suppresses the birds from approaching the steel tower by being intimidated by their traveling. A hangar 5 of the threatening body 3 (traveling machine 2) is attached to the top of the tower, and the threatening body 3 is stored in the hangar 5 when the traveling machine stops, and is configured to jump out of the hangar 5 only when traveling. ing.

As the guide rail 1, a rail for a fall prevention device used when ascending and descending a steel tower is used. As shown in FIG. 2, the rail 1 is a metal rail having a substantially I-shaped cross section, having an engaging surface 1A and a mounting surface 1B which are parallel to each other, and an intermediate surface 1C which is perpendicular to these, and an engaging surface 1A. It is configured to be joined to the mounting surface 1B. A large number of rectangular holes 6 with which sprockets of the traveling machine 2 to be described later mesh with each other are continuously formed in the engagement surface 1A.

The mounting surface 1B is gripped by a gripping metal 7 (FIG. 4), and the gripping metal 7 is formed integrally with the mounting metal 4 for holding the rail 1 on a steel tower. An anti-vibration rubber (not shown) is interposed between the grip metal 7 and the rail 1 so as to reduce vibration noise when the traveling machine travels.

Further, as shown in FIG. 2, a feeder line 9 is provided on an intermediate surface 1C of the rail via an insulator 8.
The traveling machine 2 travels by driving a motor of a driving mechanism by receiving a power supply by sliding a contact point on the power supply line 9. Two power supplies are prepared, the first power supply is turned off by a timer described later for a predetermined time (for example, 50 minutes), and the second power supply is a drive in which the first power supply is turned off and stopped. Machine 2
Travels to the hangar 5 and stops. To stop at the hangar 5, a “sensor” such as a magnetic sensor is installed near the hangar 5, and the traveling machine 2 is stopped by detecting that the traveling machine 2 is stored in the hangar by the sensor. Good. Instead of providing the power supply line 9 along the rail, as shown in FIG. 1, the power supply cable 10 may be drawn directly to the traveling machine. As a power supply for supplying power to the power supply line, a power supply for an aviation obstacle light installed in a steel tower was used.

The traveling machine 2 (FIGS. 2 and 3) includes a sprocket (not shown) that meshes with the rectangular hole 6 of the engagement surface 1A, and a motor (not shown) that rotates the sprocket. As for the mechanism in which the sprocket is rotated by the motor and travels along the rail, a lift assist device described in Japanese Patent Application No. 7-31648 can be referred to.

The threatening body 3 preferably resembles a natural enemy for a bird to be repelled. In this example, as shown in FIGS. The material of the intimidating body 3 is not particularly limited, but is made of FRP in consideration of strength in this example. The shape of the wing was almost folded in consideration of the effect of wind. The torso and wings of the hawk model are reinforced steel 11
(See Fig. 2). Further, the mounting to the traveling machine 2 is performed via the rotating shaft 12, and the threatening body 3 is configured to rotate in accordance with the wind direction according to the weathercock principle. The rotation of the threatening body 3 imparts irregularities to the movement, so that the bird repellent effect can be maintained for a long time. Then, a red LED was embedded in the eyes 13 (FIG. 3) of the hawk model, so that the bird could be intimidated by the light emission of the LED.

The mounting bracket 4 (see FIG. 4) is a bracket for supporting the rail 1 on a steel tower. One end is provided with a gripping metal 7 for the guide rail 1 and the other end is mounted on an angle member 14 of the steel tower. V bolt 15 is attached. In this example, a circular guide rail was fixed to the top of the tower with eight mounting brackets 4.

The hangar 5 has only one side surface and an upper surface and has an L-shaped cross section (see FIG. 1), or has two side surfaces and an upper surface and has a cross section] (not shown). Is mentioned. In the case of the former, the upper surface is installed so as to cover the rail, and in the case of the latter, the intimidating body 3 (the traveling machine 2) is protected from the weather by installing over the rail. The configuration of the hangar is not particularly limited as long as it covers the traveling machine 2 (threatening body 3), but a shape having a small wind pressure resistance is preferable.

A control circuit (not shown) for the traveling machine 2 is mounted on the side surface of the housing 5. FIG. 5 is a circuit diagram of the control circuit.
Shown in The AC power supply introduced from the power supply of the aviation obstacle light is converted to DC by the "switching power supply", and the "timer" and "motor drive circuit" are operated by the DC power supply. The timer defines the traveling time of the traveling machine 2 and sets a traveling start time and a traveling time (or a traveling end time). It is preferable that the threatening body 3 be run during this time, since the repellent target such as Rakutori has a tendency to flock to the steel tower in the evening. Of course, by making the above set time variable, the timing of the threat can be varied, and the habituation of the bird can be suppressed. When the traveling start time comes, the power supply of the first system is applied to the power supply line along the rail by "power system switching", and the traveling machine 2 is operated to move the threatening body 3 along the rail. At that time, a random signal is generated by a “random signal generation circuit”, and the “motor drive circuit” is controlled based on this signal to change the speed of the traveling machine 2 irregularly. For example,
Velocity is changed in the range of 10 m / min or less, and the irregularity maintains the bird repellent effect for a long time. After a predetermined time, the traveling machine 2 stops, but the stop position is not limited to the inside of the hangar. For this reason, the traveling machine 2 is switched by switching to the power source of the second system by "power system switching", and the fact that the traveling machine is stored in the hangar is detected by the "sensor" and stopped.

Although the above-mentioned threatening body 3 has a shape in which a hawk has its wings almost folded, a model having a shape in which the wings are expanded is also prepared, and the two are appropriately exchanged for use. A reduction in the repellent effect can be suppressed. In the above description, the mounting location of the apparatus of the present invention is the top of the tower, and the shape of the guide rail is circular. However, the mounting location and the shape are not limited to such. The mounting location may be any location where the bird approaches, and the shape of the guide rail may be linear.

[0019]

As described above, according to the apparatus of the present invention, the threatening body runs along the guide rails to repel birds, and without causing danger to the birds and the person handling the apparatus, It is possible to prevent buildings and the like from being stained by feces such as ryokutori. In particular, by changing the direction of the threatening body like a weathercock or making the running speed irregular, the bird repelling effect can be maintained for a long time.
