Description

  The present invention relates to a bird damage prevention device attached to an arc horn, and a rolling stopper used for preventing the bird damage prevention device from overturning.

  In general, in an insulator device for insulating and supporting an electric conductor such as a transmission line installed on a pillar such as a steel tower that supports a stretched transmission line or the like, when an electric shock such as a lightning strike occurs on the electric conductor In addition, two rod-shaped arc horns are provided on both the ground side and the charging side on both sides of the insulator row to cause a flashover between the insulator rows of the insulator device and to protect the insulator from destruction by arc heat. ing. The two arc horns each have a base end portion extending substantially perpendicularly to the insulator row from the end portion of the insulator row, and an extension portion that is bent and extended in the direction of the insulator row from the distal end of the base end portion. The rods have a round bar shape having a convex portion that is bent and extended in a direction away from the insulator from the tip of the elongated portion, and are arranged facing each other. And when the flying bird stops on this arc horn and tries to stop, or when flying, the spread wings come into contact with both arc horns to prevent an accident that short-circuits between the arc horns. The arc horn is equipped with a bird damage prevention device that prevents the bird from stopping.

  This kind of bird damage prevention device is generally fitted with a support part formed along the extended part of the arc horn and a substantially C-shaped cross section formed on one surface of the support part. And a plurality of bar-shaped barrier bar bodies established on the other surface of the support part. This bird damage prevention device is mounted by fitting a fitting portion to the extending portion of the arc horn, and at this time, the barrier rod body is mounted in such a direction as to extend in a direction away from the insulator. This barrier rod prevents the bird from stopping on the arc horn and the spread wings from contacting both arc horns.

  Further, Japanese Patent Laid-Open No. 6-98450 (Patent Document 1) proposes a bird damage preventer for mounting on an arc horn having a curved shape as described above. This bird harm prevention device includes a support part formed in a semi-cylindrical body with a soft material that can be bent so as to follow the curve of the arc horn that is deposited along the curved arc horn, and the length of the support part. Fitting portions formed in such a manner that the substantially C-shaped cross-sections having slits for inserting arc horns at both ends in the direction and the openings having the substantially C-shaped cross-sections are opposite to each other, and support portions thereof And a large number of needle-like barrier rods projecting radially from the fitting portion, and the support portion, the fitting portion, and the barrier rod body are integrally formed. The anti-bird damage device is attached to the arc horn by fitting or fitting the fitting portion to the arc horn through the slits at both ends of the support portion. It is made to stick out so that the bird cannot stop at the arc horn.

JP-A-6-98450

  However, in the above-described bird shape preventer having the general shape, the fitting portion having a substantially C-shaped cross section is only fitted to the extension portion of the arc horn, so that, for example, the bird wing strongly hits the barrier rod. If a predetermined external force such as strong wind blows on the bird damage prevention device, the bird damage prevention device may be detached from the arc horn, or it may fall over the arc horn extension and the barrier rod There are times when it enters between the arc horn and the eggplant. If this happens, it will no longer function as a bird harm preventer. Therefore, after a power outage, an operator climbs a pillar such as a steel tower and installs the bird harm preventer again or installs the bird harm preventer with an arc horn. It was necessary to perform an operation for returning the barrier rod to the original position by rotating the extension portion of the barrier rod about the shaft.

Although it can be mounted, there may be a case where the displacement, detachment, or the like cannot be prevented. For example, if a flying bird, a strong wind, or an object blown by a strong wind collides with the barrier rod from the extending direction of the support part of the bird protection device, the bird protection device is positioned in the extension direction of the support part. There is a concern that a shift occurs, and in turn, a part of the bird damage prevention device from the arc horn is detached. In addition, the bird damage prevention device itself is made of a soft material that can be bent until the position of the bird damage prevention device does not shift or detach, and sufficient strength such as torsional rigidity is not secured. There is also a concern that a part of the fitting portion receives a rotational force from the barrier rod body and falls over the arc horn as a shaft due to the action of a predetermined external force. As a result, the barrier rod body deviates from the position it should originally occupy, and the function of preventing bird damage by the barrier rod body is not fulfilled. Then, returning the fallen barrier bar to the original position is performed by rotating the fitting part in which the barrier bar is integrally formed, but it is necessary to make a power failure every time the barrier bar falls. The work is extremely complicated and economically disadvantageous.

(Fourth embodiment)
A fourth embodiment will be described with reference to FIGS. 10 and 11. In FIG. 10 and FIG. 11, the same components as those of the third embodiment are denoted by the same reference numerals as those of FIG. 8 and FIG.

  In the fourth embodiment, the slit 92a connected to the insertion opening 92 in the insertion portion 90b of the plate-like portion 90 is cut out from the short side portion 91c on the distal end side of the extension portion 10b of the arc horn 10 to form the third embodiment. It has the same effect as the form.

  FIG. 10 is a perspective view of the bird damage prevention device 80 attached to the arc horn 10. The bird damage prevention device 80 of the present embodiment is made of a tough insulating material such as FRP as in the above embodiments, and includes a fitting portion (not shown) that fits the arc horn 10 and a fitting portion. A plate-like support portion 90a that is attached and fixed to the upper portion of the arc horn 10 and extends along the extension portion 10b of the arc horn 10, and a plate-like insertion that extends from the plate-like support portion 90a toward the distal end of the extension portion 10b.

In addition, the fitting part is provided with a bolt insertion port (not shown) as in the above embodiments.

  In the present embodiment, the bird damage prevention device 80 stably attaches the support portion 90a to the elongated portion 10b of the arc horn 10 by the predetermined fitting force of the fitting portion, and the barrier rod body receiving portion 82 is interposed therebetween. Each of the barrier bars 84 is attached to the support portion 90a, and the fitting portion, the support portion 90a, the insertion portion 90b, and the barrier rod body 84 are integrally formed to be fixedly supported. In addition, the barrier bar body 84 in the present embodiment can be in a posture state in which the barrier bar body receiving portion 82 is directly attached to the support portion 90a, so that it stands in any direction. For example, the barrier rod 84 on the distal end side of the extending portion 10b of the arc horn 10 is attached and fixed to the support portion 90a so as to stand up toward the front side of the figure, while the base of the extending portion 10b of the arc horn 10 is fixed. The barrier bar 84 on the end side is fixedly attached to the support portion 90a so as to stand up toward the back side in the figure. Further, similarly to the above embodiments, the barrier rods 84 are arranged in a line along the extending direction of the extending portion 10b of the arc horn 10. For example, the barrier bars 84 are arranged in a line.

  Next, the plate-like portion 90 of the bird damage prevention device 80 will be described. FIG. 11 is a plan view of only the plate-like portion 90 in the present embodiment.

  The plate-like portion 90 extends along the extending portion 10b of the arc horn 10 and the insertion extending through the protruding portion 12 of the arc horn 10 is extended from the supporting portion 90a toward the distal end of the extending portion 10b. It is integrally formed by the insertion part 90b in which the part 92 is provided.

  The plate-like portion 90 connects the pair of left and right long side portions 91a and 91b extending with a predetermined length along the extended portion 10b of the arc horn 10 and the opposite end portions of these long side portions. It is constituted by a substantially rectangular plate-like member having a short side portion 91c on the distal end side of the extending portion 10b and a short side portion 91d on the proximal end side of the extending portion 10b.

  The plate-like portion 90 may be formed by changing the thickness of the plate-like portion 90 as in the third embodiment, or the rolling stopper 30 of the first embodiment and the rolling of the second embodiment. The stopper 50 may be formed with a uniform thickness.

  The insertion port 92 of the insertion portion 90b has a size that allows the projection 12 of the arc horn 10 to be inserted, similarly to the insertion port 72 of the insertion portion 70b of the plate-like portion 70 in the third embodiment. An opening is formed in the vicinity of the short side portion 91c on the distal end side of the elongated portion 10b. The insertion opening 92 is formed in a vertically long ellipse having a longer width in the extending direction of the extending portion 10b of the arc horn 10 than in the width in the left-right direction. The width in the left-right direction of the insertion opening 92 is set to such an extent that the convex portion 12 of the arc horn 10 can be easily inserted through the outer diameter of the arc horn 10.

  The insertion opening 92 of the plate-like portion 90 is formed by cutting out from the short side portion 91c on the distal end side of the elongated portion 10b in the plate-like portion 90 toward the insertion opening 92, in addition to being formed in a vertically long elliptical shape. A slit 92a is formed.

In a state where it is expanded in the width direction of the arc horn and elastically deformed alternately in the vertical direction as necessary, the insertion port 92 is inserted into the convex portion 12 of the arc horn 10 and the elastic deformation of the plate-like portion 90 is released to simplify the operation. Thus, the bird damage prevention device 80 can be mounted on the arc horn 10. Therefore, the work efficiency of attaching the bird damage prevention device 80 to the arc horn 10 can be greatly improved.

  Further, even if the slit 92 a is provided in the insertion opening 92 of the plate-like portion 90, the convex portion 12 of the arc horn 10 has the slit 92 a when a predetermined external force is applied to the barrier rod 82 of the bird damage prevention device 80. Since it does not pass through and is not detached from the insertion port 92, the same effect as the insertion port 72 in the third embodiment can be achieved.

Can be prevented.

  Further, the plate-like portion 90 is provided with concave portions 96 facing each other along a pair of left and right long side portions 91a and 91b. Each of the recesses 96 is provided at predetermined intervals along the left and right side portions 91 a and 91 b of the plate-like portion 90. As in each of the above embodiments, the plate-like portion 90 is formed by arcing a fixing band (not shown) having engagement portions that can be engaged with the left and right concave portions 96 from the lower side of the plate-like portion 90. The bird damage preventer 80 can be fixed and supported integrally with the arc horn 10 by surrounding the extending portion 10b of the horn 10 and engaging the engaging portions of the fixing band with the respective recesses 96. Has been. Thereby, the fixed support of the bird damage prevention device 80 with respect to the arc horn 10 becomes strong, and the bird damage prevention device 80 can maintain the initial set position particularly when receiving external force in the height direction. If the bird damage preventer 80 can be integrally fixed and supported to the arc horn 10 by the fixing band, the concave portion 96 of the plate-like portion 90 is formed on one of the long side portions 91a and 91b as in the above embodiments. It is also possible to provide a configuration.

  The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

  For example, although the bird damage prevention device of each embodiment is configured to be provided for at least one arc horn 10, the bird damage prevention device may be provided for both arc horns. In this case, the other arc horn 10 has the same configuration as that of the one arc horn 10 and is provided with a convex portion 12 in a direction away from the insulator row 4 by being bent at the tip of the extending portion 10b. Thereby, the bird damage prevention function of the bird damage prevention device can be further enhanced.

  Further, the rolling stoppers of the first embodiment and the second embodiment can be configured not to store all the barrier rods in the second insertion port as long as the bird's damage prevention device can be prevented from falling. . For example, in the case of a bird damage prevention device in which barrier rods are erected so as to form a row in the extending direction of the arc horn, which are arranged in parallel in a direction intersecting the extending direction of the arc horn, respectively. It is also possible to store at least one row of barrier rods in the second insertion opening of the rolling stopper in the row.

  Further, the second insertion port 34 in the first embodiment is configured to be formed in an approximately U-shape, but if it is formed in a slit shape and can accommodate the barrier bar body 24 standing upright. For example, it is also possible to form an opening in a substantially V shape.
