A tubular portion to be attached to the electric wire, a protrusion provided along the longitudinal direction above the tubular portion, a dividing portion that divides the tubular portion below the tubular portion, and extends below the dividing portion. In a protection tube for bird damage countermeasures having a protruding portion, a mounting portion for attaching a strip-shaped flexible spacing piece for connecting the protruding portions of each bird damage countermeasure protective tube to each other is provided at both ends of the protruding portion. A protective tube for bird damage control, which is characterized by

[Operation] In order to mount the bird damage countermeasure protective tube (hereinafter, also referred to as a protective tube) configured as described above on the electric wire E, the divided portions of this protective tube are separated from each other to the left and right, and Cover the wire E.

Since the weight of the lower protruding portion is appropriately larger than the weight of the upper protruding portion of the tubular portion of the protective tube attached to the electric wire, the protruding portion is always located above. In addition, since the upper portion of the inner peripheral surface of the tubular portion of the protective tube for bird damage control is supported by the upper surface of the electric wire E, the protective tube can swing left and right around the contact support portion with the upper surface of the electric wire E. And further,
Since the mounting portions for attaching the strip-shaped flexible spacing pieces that connect the protruding portions of the protective tubes to each other are provided at both ends of the protruding portions, even if the spacing pieces that connect the protective tubes are attached, The swing of each protective tube with respect to the electric wire is not so restricted,
Independent swingability of each protection tube can be maintained and ensured, the connection structure of each protection tube is simple, cost is low, and
Installation work of protective tubes that connect each protective tube can be performed very easily. When such a protective tube for bird damage is attached to the electric wire E, the bird cannot be stopped on the electric wire, so that the occurrence of bird damage can be prevented.
The installation is also easy.

[Embodiment] An embodiment will be described with reference to the drawings. FIG. 1 is a perspective view of a bird damage protection tube, and a bird damage protection tube 1 is shown.
Is made of synthetic resin, and this protection tube is provided with a cylindrical portion 2 for attaching to the electric wire E, and a projection 3 for preventing the bird B from stopping is provided above the cylindrical portion 2. A projecting portion 4 is provided on the side opposite to the projecting portion 3 and projecting downward. The lower protruding portion 4 is configured to have an appropriate weight which is about twice the weight of the protruding portion 3 or more, and when the protective tube 1 is attached to the electric wire E, the weight of the protruding portion 4 causes the lower portion of FIG. As shown in FIG. 3, the protrusion 3 is always directed upward, and the protrusion 4 is attached at a lower position. Also, protective tube 1
The upper portion of the inner peripheral surface of the cylindrical portion 2 is brought into contact with and supported by the upper surface of the electric wire E. Therefore, if bird B stops in this protective tube 1,
As shown in the figure, it is hard to stop because of the protrusions 3, and the protection tube 1 swings in the direction of arrow F around the contact portion on the upper surface of the electric wire E, and the bird B becomes unstable and cannot stay. ing.

The lower protrusion 4 is composed of two protrusions 4'and 4 ', and each protrusion 4'and 4'is connected to the lower end of the wall member forming the tubular portion 2. Has been done. Therefore, the protruding portion 4 has a vertical dividing portion 4 ″, and when the protruding portions 4 ′, 4 ′ are pulled to the left and right, the vertical dividing portion 4 ″ causes the two pieces to be separated from each other. As shown in FIG. 2, the projecting pieces 4'and 4'are in contact with each other.

Further, as shown in FIG. 4, the protruding portion 4 is continuously provided at one lower end of the wall member constituting the tubular portion 2, and is divided between the protruding portion 4 and the other lower end of the wall member. It is also possible to configure the part 4 ″.

Further, when a protrusion 7 is provided on the upper portion of the inner peripheral surface of the tubular portion 2 of the protective tube 1 as shown in FIG.
The protective tube comes into contact with the upper surface of the bird and becomes more easily rocked, and the rocking degree is increased so that the bird B cannot be stopped further.

The protective tube 1 has a length of about 2.5 m, and holes 5 are formed at both left and right ends of the protruding portion 4. As shown in FIG. 6 (a), when a plurality of protective tubes 1 are attached to a suspended curved (catenary) electric wire E, a flexible spacing piece (for example, easily bent) is provided in the hole 5 of each protective tube. Attach the protrusion 6A of the strip-shaped plastic plate 6 by press fitting. Since the spacing piece 6 is flexible, the protection tubes are connected so as to be separately swingable.

By the way, in order to construct a protection device against bird damage, the lower divided portion 4 ″ of the tubular portion 2 of the protective pipe is separated, and the protective pipe 1 is attached to the electric wire E from the separated divided portion 4 ″. Then, as shown in FIG. 6, the protective tubes are connected by the spacing pieces 6 to form a bird damage countermeasure protective device.

The projection 3 may not be a series of strip-shaped projections, but may be a plurality of projections 3, and the lower protrusion 4 may not be a series of strip-shaped projections.

Since the divided portion of the protective tube is usually closed, it does not come off from the electric wire even if the protective tube rotates during use.

[Effect] Since the present invention is configured as described above, when the protective tube 1 is attached to the electric wire E, the lower divided portion 4 ″ of the protective tube is pulled left and right to be separated, and the electric wire is separated from this separated portion. Since it covers E, it is easy and easy to install it on the utility pole.

Moreover, since the projection 3 is always arranged above the protective tube, it is difficult for birds to be caught on the protective tube 1. further,
As shown in FIG. 3, the protective tube 1 has an upper portion of the inner peripheral surface of the tubular portion 2 abuttingly supported on the upper surface of the electric wire E, so that even if the bird B perches on the protective tube 1, The protective tube 1 swings in the direction of arrow F around the contact portion on the upper surface of the electric wire E, becomes unstable, and the bird cannot be stopped. In addition, since the protective tube is connected to the holes provided at both ends of the projecting portion of the protective tube with the projecting portions provided on the strip-shaped flexible spacing pieces, the rotational resistance of the connecting portion is small, The swing of each protective tube with respect to the electric wire is not so restricted, and independent swingability of each protective tube can be maintained and secured, and the effect that birds can be less likely to stop in the protective tube for bird damage countermeasures is exerted. Further, also in the work of installing a plurality of protective tubes to the electric wire, it suffices to simply press-fit and engage the protruding portions provided on the spacing pieces with the holes provided at both ends of the protruding portions of the respective protective tubes. The work of installing the protective tube is extremely simple and has the effect of being able to perform it quickly.

Further, as shown in FIG. 5, when a protruding portion 7 is provided on the upper part of the inner peripheral surface of the tubular portion 2 of the protective tube 1, the protective tube 1 is further swung around the contact portion on the upper surface of the electric wire E. The bird B cannot be stopped further because the swinging degree becomes larger.
