Description

TECHNICAL FIELD The present invention relates to a bird damage prevention device.

High voltage wires are attached to a retaining clamp when installed on a utility pole. The stay clamp is connected to a tension insulator and attached to a utility pole via the tension insulator. In other words, the high-voltage electric wire is installed on the utility pole by the restraining clamp and the tension insulator.

This retaining clamp is housed in a clamp cover having insulating properties when it is used for installing electric wires. The clamp covers are a pair of covers that are connected by hinges so as to be able to be opened and closed, as disclosed in Patent Document 1, for example. When storing the anchoring clamp in the clamp cover, the anchoring clamp is accommodated inside by inserting the anchoring clamp inside with the clamp cover opened and then closing the clamp cover. Then, the pair of engaging portions provided on the clamp cover are engaged using, for example, an indirect live wire tool, and the clamp cover is fixed in a closed state. Also, the clamp cover is formed with a hole for introducing an overhead wire on a side portion and a hole for leading out an edge wire on the opposite side portion. The clamp cover also has a hole for connecting the retaining clamp to the external tension insulator on the same side as the hole for leading out the edge-side electric wire. A pair of engaging portions are provided at a plurality of locations, and are also provided between the hole for introducing the electric wire and the hole for connecting the retaining clamp to the tension insulator.

FIG. 3 is a side view of the clamp cover. 2 is a side view of the clamp cover 10 opened, and FIG. 3 is a side view of the clamp cover 10 closed. 2 and 3 show a state in which the retaining clamp 1 is housed inside the clamp cover 10. As shown in FIG.

As shown in FIG. 2, the anchoring clamp 1 has a body portion 2, a wedge portion 3, a wire fixing portion 4, and an insulator connecting portion 5. As shown in FIG. The body portion 2 is slidably connected to a triangular wedge portion 3 . The body portion 2 accommodates the stripped portion of the electric wire A and the end portion of the wedge portion 3 .

The wedge portion 3 accommodates a portion of the electric wire A from which the coating is peeled off in the groove. An electric wire fixing portion 4 is attached to the wedge portion 3 , and the electric wire A is fixed (clamped) by tightening the portion of the electric wire A from which the coating is peeled off by the electric wire fixing portion 4 . The insulator connection portion 5 is a ring-shaped member connected to the main body portion 2 . The insulator connection portion 5 is attached to the insulator shaft Ba of the insulator B by a shaft provided inside the ring. The anchoring clamp 1 thus anchors the wire A and is connected to the insulator B.

The clamp cover 10 is an insulating cover that covers the anchoring clamp 1 configured as described above and accommodates the anchoring clamp 1 inside. As shown in FIG. 2, the clamp cover 10 has a first body portion 12A, a second body portion 12B, and a hinge portion 14. As shown in FIG. The first main body portion 12A and the second main body portion 12B are a pair of covers that are connected via a hinge portion 14 so as to be openable and closable. The clamp cover 10 is composed of an elastically deformable insulator.

FIG. 4 is a diagram showing an example of attachment of the bird damage prevention device according to the embodiment. 5 is an arrow diagram of the bird damage prevention device shown in FIG. 4. FIG.

As shown in FIG. 4 , the bird damage prevention device 20 according to the embodiment includes a bird damage prevention portion 21 , a clamp portion 22 and a connecting member 23 . The clamp portion 22 is made of an insulator that is elastically deformable. As shown in FIG. 5, the clamp section 22 includes a pedestal 221, holding sections 222a and 222b, and retaining sections 223a and 223b.

In this embodiment, the bird damage prevention device 20 is provided so that the bird damage prevention part 21 is arranged right above the clamp cover 10, as shown in FIG. The bird damage prevention unit 21 will be described later.

Specifically, the bird damage prevention part 21 is provided on a pedestal 221 of the clamp part 22, and is held in a state in which the clamp cover 10 is sandwiched from both sides by clamping parts 222a and 222b provided extending downward from the pedestal 221. be.

The connecting member 23 is provided so as to extend in the direction toward the utility pole C from the clamp portion 22 . In the clamp portion 22, the connecting member 23 and the cross arm D are connected by the fixing members 24 and 25. As shown in FIG. The fixing members 24 and 25 are exemplified by screws 24 and nuts 25, for example.

FIG. 6 is a diagram showing a method of attaching the bird damage prevention device according to the embodiment. As shown in FIG. 6, the retaining portions 223a and 223b of the clamp portion 22 are opened in the direction indicated by solid arrows against the elastic force of the holding portions 222a and 222b, and attached to the clamp cover 10 in the direction indicated by the white arrows. Thereby, the clamp cover 10 is maintained in a sandwiched state by the elastic force of the sandwiching portions 222a and 222b. In this state, the connecting member 23 and arm D are connected by the fixing members 24 and 25 . Thereby, the bird damage prevention part 21 is fixed directly above the clamp cover 10 .

The clamp cover 10 is held between the holding portions 222 a and 222 b of the clamp portion 22 . This prevents the clamp cover 10 from opening.

Also, the distance between the tips of the retaining portions 223 a and 223 b is smaller than the width of the clamp cover 10 . This prevents the bird damage prevention device 20 from coming off the clamp cover 10 even if it is fanned by wind or the like.

FIG. 7 is a side view showing one configuration example of the bird damage prevention unit of the bird damage prevention device according to the embodiment. 8 is an arrow diagram of the bird damage prevention part shown in FIG. 7. FIG.

In this embodiment, the bird damage prevention unit 21 includes a bird avoidance sound generator 211 , a windmill 212 , a battery 213 , and a photovoltaic panel 214 . In addition, the structure of the bird damage prevention part 21 is not limited to the structure shown in FIG.7 and FIG.8.

The bird avoidance sound generator 211 includes, for example, a non-contact sensor that detects the proximity of birds, a speaker and a sound source that generate sounds disliked by birds, and the like. As a non-contact sensor, for example, a pyroelectric infrared sensor is exemplified, but a thermopile sensor, an ultrasonic sensor, a photo sensor, or the like may also be used. When the bird avoidance sound generator 211 detects the approach of birds, it generates a sound disliked by birds. There is no limitation to the types of sounds or sound sources that birds dislike.

The windmill 212 rotates by receiving wind on the blades 212a. A reflector 212b is provided on the blade 212a. When the windmill 212 rotates by receiving the wind on the blades 212a, sunlight or the like is diffused by the reflecting plate 212b. This can enhance the intimidating effect on birds. In this embodiment, an example in which two windmills 212 are provided is shown, but the present invention is not limited to this. Also, the number of blades 212a of the windmill 212 is not limited. A mode in which the blade 212a itself is made of a reflecting member may be used.

In this embodiment, the battery 213 is, for example, a secondary battery such as a lithium ion battery. A battery 213 supplies power to the bird avoidance sound generator 211 . The photovoltaic panel 214 generates photovoltaic power from sunlight to generate power and charge the battery 213 . As a result, a self-supporting bird damage prevention device 20 that does not require power supply from the outside can be configured.

As described above, the bird damage prevention device 20 according to the embodiment is composed of the bird damage prevention portion 21 and the elastically deformable insulator, and the bird damage prevention device 20 is placed right above the clamp cover 10 that houses the restraining clamp 1 on the inner surface. and a clamp portion 22 for fixing the damage prevention portion 21 .
