Description

  The present invention relates to an animal repellent device for electric wires that prevents an animal such as a bird or a spider from riding on an electric wire or its peripheral equipment, and more particularly to a mechanism that is installed on an electric wire and prevents an animal from approaching by a needle-like protrusion.

Various overhead wires such as power transmission lines, telephone lines, and cable TV signal lines are wired outdoors. Numerous birds such as crows, pigeons and starlings fly on these wires and stop, or small animals such as cormorants, squirrels and weasels are causing various problems.
For example, animal droppings may adhere to the surface of the electric wire and deteriorate, or the nail may be scratched. In addition, it can cause accidents where animals are beaten or short-circuited by their bodies. In addition, animal droppings are falling and annoying local residents. Therefore, techniques for keeping these animals away from electric wires have been developed.

In the invention described in Patent Document 1, a protrusion is planted on one surface of a belt-like belt portion, and a notch portion is provided at one end of the belt portion, and the engagement is released when the other end is engaged with the notch portion. The bird damage prevention tool provided with the brake part provided with the nail | claw for prevention to come off is disclosed.
The invention of this document is intended to prevent power transmission accidents and damage when it is detached from an electric wire, as well as not requiring time and effort for attachment, and an object to be attached is not limited.

  In the configuration of the present invention, since it is necessary to install a large number of belt-shaped belt portions on the electric wire, workability relating to installation and replacement is poor. In addition, since a large number of bird damage prevention tools having a complicated structure must be manufactured, there is a problem that the manufacturing cost increases.

  The invention described in Patent Document 2 includes a spiral tape body and a needle-like protrusion provided so as to protrude from the outer peripheral surface of the tape body, and the tape body is wound around a long body such as an electric wire. We provide a bird damage prevention device. Then, a through hole through which the protrusion can be passed is formed at one end of the tape body, and the tape bodies are connected to each other through a needle-like protrusion provided at an end of another tape body.

  According to the invention of this document, a configuration that is advantageous in that a large number of bird harm prevention devices can be continuously and efficiently attached to an electric wire, there is little risk of dropping off, and the number of parts is small. ing. On the other hand, since it is necessary to wind the tape body around an electric wire or the like, there is a problem that the method of installation or replacement is limited, and it is difficult to wind unless the cross section of the wound electric wire or the like is substantially circular. Moreover, the operation | work which connects tape main bodies needs to be performed in the field after winding to an electric wire etc., and when the length of one tape main body is short, a connection location will increase. Increasing the length of the tape body can reduce the number of connection points, but increases the number of parts that must be cut off in vain.

Japanese Patent Laid-Open No. 2003-219785 Utility Model Registration No. 3137047

  The present invention was created to solve these problems of the prior art, and is an animal repellent device for electric wires that can effectively repel animals, and selects the shape and installation environment of the electric wires to be attached. It aims at providing the structure which can be installed and replaced easily.

In order to solve the above problems, the present invention provides the following animal repellent device for electric wires.
That is, an animal repellent device for electric wires that prevents an animal from getting on the electric wires, and a rod-like horizontal base that is installed substantially parallel to the longitudinal direction of the electric wires, and at least three radial directions from the horizontal base At the same time as protruding, it has a needle-like protrusion in series in the longitudinal direction at substantially equal intervals, a first connecting part at one end of the horizontal base, and a second connecting part at the other end, and a two-way needle-like protruding part This row stably holds the horizontal base with the electric wire interposed therebetween.

The first connecting portion includes a through hole through which the needle-like protrusion protruding from the second connecting portion of the other animal repellent device for electric wires and a fitting convex portion protruding in a direction opposite to the direction of the penetrating protrusion. On the other hand, the 2nd connection part is provided with the fitting hole for fitting the fitting convex part which protruded from the 1st connection part of the animal repellent device for other electric wires.
Thereby, when connecting two this instrument, if a needlelike projection part is penetrated to a penetration hole, a fitting convex part will be fitted and connected to a fitting hole at the same time.

  In the animal repellent device for electric wires described above, the length of the needle-like protrusions may be at least one pair of needle-like protrusions that are radially adjacent to each other relatively longer than the other needle-like protrusions.

In the animal repellent device for electric wires described above, the protruding positions in the longitudinal direction of the needle-like protrusions may be arranged at positions where the directions in the plurality of directions are sequentially changed at the same interval in the longitudinal direction of the electric wires .

  In the animal repellent device for electric wires described above, the cross-sectional shape of the horizontal base portion may be formed so as to form a rib shape that matches the protruding direction of the needle-like protrusion portion.

The present invention has the following effects.
That is, since the first connecting portion is provided with a through-hole through which the needle-like protrusion is passed, the second connecting portion can be provided with the needle-like protrusion, and the needle-like protrusion is suitable at an interval suitable for avoiding animals. Protrusions can be arranged. In addition, since the needle-like protrusion and the through hole are fitted, it has a strong resistance to a pulling / compressing force in the longitudinal direction and a force in the twisting direction.

  Further, the fitting convex part of the first connecting part protruding in the direction opposite to the direction through which the needle-like protrusion part of the second connecting part penetrates can be fitted simultaneously with the penetration of the needle-like protrusion part, so that the connection workability is good. In addition, a strong connection can be achieved.

  According to the configuration of the present invention in which the row of needle-like projections in two directions sandwiches the electric wire, a large number of serial needle-like projections are in contact with the electric wire, so that the horizontal base is stably placed on the electric wire. In addition to the case where the cross section of the electric wire is circular, the electric wire can be reliably placed not only in the case of a square shape but also in the case of an indefinite shape in which a plurality of electric wires are bundled.

  In addition, by making the length of the needle-like protrusions longer than the other needle-like protrusions by at least one pair of adjacent rows, it is possible to appropriately select the rows to be sandwiched according to the diameter of the electric wire. . In other words, in the case of a small-diameter electric wire, the electric wire can be sandwiched between the short needle-like protrusions, and in the case of a large-diameter electric wire, it can be sandwiched between the long needle-like protrusions to contribute to stability improvement. To do.

  When storing and transporting multiple animal repellent devices for electric wires, it is possible to stack in a small space while providing sufficiently long needle-like protrusions by aligning and overlapping the long needle-like protrusions. it can.

  According to the configuration in which the protruding positions in the longitudinal direction of the needle-like protrusions are displaced for each radial direction, it is possible to effectively increase the needle-like protrusions that interfere with animals. That is, the needle-like projections that interfere with the animal at the same time are not limited to one row, but also interfere with the needle-like projections in adjacent rows. Therefore, if each row is displaced in the longitudinal direction, even if there is an interval in the longitudinal direction of a certain row, the needle-like protrusions in the immediately adjacent row protrude into the interval, so a continuous empty space Becomes smaller. Even if birds or small animals try to put their feet on the empty space, the body tends to interfere with the needle-like protrusions in the other rows.

  By providing radial ribs in the cross-sectional shape of the horizontal base, the strength of the connecting portion between the needle-like protrusion and the horizontal base can be increased, and from the needle-like protrusion toward the center of the horizontal base Since one straight line is formed, the stability when placed on the electric wire is improved. In addition, the stacking property between the horizontal bases is improved when the devices are stacked.

It is the top view and front view of the animal repellent device for electric wires which concern on this invention. It is right side sectional drawing of this instrument. It is explanatory drawing which showed a mode that this instrument was installed on an electric wire. It is explanatory drawing at the time of stacking this instrument. It is a perspective enlarged view at the time of connecting this instrument. It is a figure which shows another Example of this instrument.

Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings. The embodiment is not limited to the following.
FIG. 1 shows an animal repellent device for electric wires (hereinafter, this device) according to the present invention. Fig.1 (a) is a top view of this instrument (1), FIG.1 (b) is a front view. FIG. 2 is a right side sectional view of the same.

This device (1) is used by directly fixing to the electric wire in order to prevent small animals such as birds, frogs and squirrels from getting on the electric wire such as the power line and the signal line. Moreover, it can also be used by fixing to equipment related to the electric wire, for example, a brace that supports the electric wire on the electric pole via an insulator.
In consideration of recyclability, it is integrally molded with a single-color polypropylene, and the entire device is lightweight so that no load is applied to the wires. In addition to being able to reduce costs by reducing the number of parts by using a single-piece molding, in the unlikely event that it falls, it is lightweight, causing damage to passersby and physical damage to automobiles, etc. It can be prevented from occurring.

This instrument (1) has a rod-like horizontal base (2) installed substantially parallel to the longitudinal direction of the electric wire, and needle-like protrusions (21), (22), (23) from the horizontal base (2) in four directions. Many (24) are arranged.
A needle-like protrusion (21) that is relatively long in the right direction in FIG. 2 (backward in the front view of FIG. 1B), a short needle-like protrusion (22) in the upward direction (same as above), The short needle-like protrusions (23) facing forward and the long needle-like protrusions (24) facing downward (same, downward) are directed radially from the horizontal base (2).

  Each needle-like projection (21) (22) (23) (24) has a needle-like portion (21a) (22a) (23a) (24a) at the tip, and interferes with the body of the animal trying to get on the wire. It is configured to avoid it.

  As is apparent from FIG. 1, the needle-like protrusions in the respective directions are arranged in series at substantially equal intervals in the longitudinal direction. In FIG. 1, only the right end portion and the left end portion are provided with reference numerals. For example, from the upward needle-like protrusion (21) provided at the left end in FIG. 1 (a), the same needle-like protrusion (21) at the right end is provided. All the processes up to are the same. The same applies to the other needle-like protrusions (22), (23), and (24).

  As shown in FIG. 3, in this instrument (1), an electric wire to be attached is sandwiched and held between two rows of needle-like projections. Since each acicular protrusion is in series with the electric wire in parallel, a large number of acicular protrusions can be in contact with the electric wire and stably fixed to the electric wire. Although the attachment method to an electric wire is arbitrary, the structure which winds a horizontal base (2) and an electric wire using a wire, a belt body, etc. is simple.

As described above, the needle-like projections are provided with two types of lengths, that is, the long needle-like projections (21) and (24) and the short needle-like projections (22) and (23). The main purpose of this is to flexibly cope with various cross-sectional shapes of electric wires. For example, in Fig.3 (a), in order to attach to a small diameter electric wire (5), it is made to pinch | interpose between short needle-like projection parts (22) (23). In FIG.3 (b), the electric wire (6) with a big cross section is pinched | interposed between long needle-like projection parts (21) (24).
Thus, by providing two types of long and short needle-like protrusions, it is possible to cope with electric wires of various sizes while making all the needle-like protrusions smaller than making them longer.

  The point which does not ask | require the cross-sectional shape of an electric wire is also mentioned as an advantage of this invention. Fig.3 (a) is the electric wire (5) which has the circular cross section assumed with the conventional similar instrument, Of course, even such a shape can be attached without a problem. Next, FIG.3 (b) is a case of the electric wire (6) which has a rectangular cross section. In the configuration in which the needle-like protrusions protrude in all directions as in the present embodiment, the rectangular electric wire has more contact portions and can be held more stably than the conventional instrument. FIG. 3 (c) shows an electric wire (7) having a more complicated shape. However, in the configuration of the present invention, the flat portion (7a) and the row of needle-like protrusions (24) are in contact with each other, and a sharp portion is formed. In addition to the contact (7b), the attachment to the electric wire (7) is good.

  In this embodiment, the needle-like protrusions are described as radially projecting in four directions. However, in the practice of the present invention, the needle-like protrusions may radiate in any direction of three or more directions. For example, in the case of three sides as shown in FIG. 3D, the angle formed between the needle-like projections (25), (26), and (27) is set to 120 degrees, and the two needle-like projections (26) (27 ) An electric wire can be sandwiched between them. Although the circular electric wire (8) is shown in the figure, for example, in the case of a substantially hexagonal electric wire or the like, the attachment property to the electric wire is further improved. Thus, the angle between the needle-like protrusions can be arbitrarily set according to the cross-sectional shape of the electric wire to be attached.

  The configuration in which the needle-like protrusions are long and short contributes to the stackability when the device (1) is stacked as shown in FIG. As shown in the figure, the necessary space is reduced by aligning the orientation of the other instrument (1) between the long needle-like protrusions, as compared with the case where all of them are long needle-like protrusions. be able to. In this instrument (1) for storing and transporting a large number of articles at the same time, it is particularly preferable that it can be configured to save space.

  The length of the needle-like projections in the present invention can be made longer than the other needle-like projections by at least one pair of adjacent rows.For example, when projecting the needle-like projections in three directions, It is only necessary to shorten one and shorten the other two. In the case of four directions, the number is not limited to two, and three may be longer and one may be shorter. In the case of five directions, for example, two may be longer, three may be shorter, two may be longer, one may be shorter, and the remaining two may be intermediate lengths.

  In this embodiment, the length of the needle-like projection is 45 mm for the longer side and 30 mm for the shorter side. This length is most suitable for birds and small animals targeted by the device (1). The length of the long hand is preferably 50 mm or less from the viewpoint of the strength of the needle and the repelling effect, and the difference between the long hand and the short hand is preferably 15 mm or more.

Next, as shown in FIG. 1, in the present invention, the protruding positions in the longitudinal direction of the needle-like protrusions (21), (22), (23), and (24) are displaced for each radial direction. That is, for example, the needle-like protrusion (22) protrudes from a position shifted 13 mm to the left in the longitudinal direction from the protruding position of the needle-like protrusion (21), and further from the position shifted 13 mm, the needle-like protrusion (23 ) Protrudes, and the needle-like protrusion (24) protrudes from a position displaced by 13 mm. In addition, the needle-like protrusion (21) protrudes from a position further displaced by 13 mm.
As described above, in this embodiment, the needle-like protrusions protrude in a spiral shape.

According to this configuration, for example, when a bird tries to stop between two upward needle-like protrusions (21) in FIG. 1B, the needle-like protrusions (22) (22) Since 24) protrudes to a position close in the longitudinal direction, the body and the body interfere with each other so that it is difficult to stop. Compared with the case where all the needle-like protrusions in each direction are arranged in the same longitudinal position, the repelling effect can be enhanced with the same number.
The displacement interval is optimally about 13 mm in this embodiment, but a range of 10 mm to 25 mm is preferable.

  FIG. 5 is an enlarged perspective view of the device (1) when connected. The first connecting part (3) attached to one end of the instrument (1) (the right end in FIG. 1) has a needle protruding from the second connecting part (4) (the left end in FIG. 1) of the other instrument (1). A through hole (31) through which the protrusion (22 ′) passes, and a fitting protrusion (32) protruding in the opposite direction to the direction of penetration.

On the other hand, the second connecting portion (4) is provided with a fitting hole (41) for fitting the fitting convex portion (32) protruding from the first connecting portion (3) of the other present instrument (1). .
As shown in FIG. 5, when the first connecting portion (3) and the second connecting portion (4) are connected through the needle-like protrusion (22 ′) through the through hole (31), the fitting convex portion (32). Is fitted into the fitting hole (41), and the lower surface of the first connecting portion (3) and the upper surface of the second connecting portion (4) are brought into close contact with each other, so that the two devices (1) can be connected.

  According to this structure, since it can provide without changing the space | interval of a needle-shaped projection part also in a connection part, there can be produced a repellent effect without omission about the installation range of this instrument (1). Therefore, the needle-like protrusion (23 ') protrudes from the first connection part (3), and the needle-like protrusion (22') protrudes from the second connection part (4).

  As for the connection part of the said Example, although the direction which connects a through-hole (31) and a fitting convex part (32) showed the example of the same direction as a needle-like projection part (22) (24), for example, 45 It may be possible to connect in a state of being rotated twice. That is, let the penetration direction and the protruding direction of the through hole and the fitting convex part (32) be the direction of the intermediate angle between the needle-like projection part (21) and the needle-like projection part (24). According to this configuration, when the needle-like projections (21) and the needle-like projections (24) or the needle-like projections (22) and the needle-like projections (23) are arranged facing downward 45 degrees. The connecting operation can be easily performed in the arrangement state.

  In the above description, the continuous horizontal bases (2) are connected in a straight line, but may be configured to be refracted and connected by a predetermined angle. For example, the through hole (31) and the fitting convex part (32) are arranged to be displaced from the axial direction of the horizontal base part (2), thereby being refracted and connected at an angle corresponding to the deviation amount. Can do. If it can be connected to the adjacent present instrument (1) so as to form an angle of 60 degrees, the present instrument (1) can be connected in a triangular shape. Similarly, the angle formed by the connecting portion may be 90 degrees, and the four instruments (1) may be connected to form an arbitrary polygonal shape, such as a square shape.

Finally, the cross-sectional shape of the horizontal base (2) will be described.
As shown in FIG. 2, the cross-sectional shape of the horizontal base portion (2) of the present invention is a rib (2a) (2b) (2c) that matches the protruding direction of the needle-like protrusions (21) (22) (23) (24). ) (2d).
By providing the radial ribs, the strength of the entire horizontal base (2) increases, and the connecting portion between the needle-like protrusion and the horizontal base, for example, the needle-like protrusion (21) and the horizontal base (2). The intensity | strength of the part which a rib (2a) connects can be increased.
Moreover, since it becomes 1 linear shape toward the center of a horizontal base (2) from a needle-like projection part (21) (22) (23) (24), stability at the time of mounting on an electric wire improves. As shown in FIG. 4, the stacking property between the horizontal bases is improved even when the present instrument (1) is overlapped.

  You may comprise the cross section of a horizontal base (2) by a hollow cyclic | annular form. By making it hollow, high strength can be maintained while achieving weight reduction.

FIG. 6 is a diagram showing another embodiment of the cross-sectional shape of the horizontal base.
FIG. 6A shows a configuration in which the constricted portions (50) are provided at predetermined intervals on the rib portions (2a) and (2c). In this alternative embodiment, the constricted portions are formed in the rib portions (2a) and (2c) at positions 90 degrees out of phase from the needle-like projecting portions (22), respectively, with the mountain-shaped constricted portions directed in the axial direction. The horizontal base (2) is configured to be easily bent at the position of the portion (50).
According to this configuration, the horizontal base (2) as a whole can be bent at the plurality of constricted portions (50) while ensuring sufficient strength, so that even when the electric wire is bent, it can be easily fitted along the electric wire. Can do.

Furthermore, FIG.6 (b) shows another Example which formed the horizontal base in the shape of a bead. As shown in the figure, it is composed of a flat ball portion (60) and a small-diameter connection portion (61) that connects the ball portions, and a needle-like projection protrudes in each direction from the ball portion, and a connection portion (61 ) Has flexibility, the entire horizontal base can be flexibly along the wire.
This embodiment also has an advantage in that it can be easily installed according to the shape of the electric wire.

Although this invention can be comprised using arbitrary materials other than the above-mentioned polypropylene, it is preferable to shape | mold by 1 type of thermoplastic resins in consideration of recyclability. That is, if the whole is composed of one kind of material, there is no need for separation at the time of recycling, and it can be molded again using the recycled material.
In addition, since the cross-sectional shape is characterized as in the present invention, sufficient strength can be ensured even in resin molding, and the length can be increased.
