Description

  In order to prevent birds from flying into an existing cable such as an optical cable (generally, a retractable cable) installed between cable holding parts such as utility poles, the present invention is stretched to prevent jumping on the cable. The present invention relates to a method for stretching Tegs and other linear bodies and a spacer used in the method.

  Various structures have been proposed in which birds cannot fly (do not stay) on the cable in order to prevent the occurrence of dung damage and other bird damage due to the birds flying (staying) on the cable. As one of them, Tegs and other linear bodies (thin enough to prevent birds from staying) are arranged side by side at a predetermined interval directly above the cable, and the wires prevent the birds from staying on the cable. There is a structure with such a structure (for example, Patent Documents 1 and 2).

  In the conventional structure, when the linear body is arranged directly above the cable, a spacer having a lower portion fastened to the cable using bolts and nuts is arranged at an appropriate interval on the cable, and the upper end of the spacer is arranged. The part is configured to support a linear body such as Tegs or other wires.

  The conventional structure has a structure in which the existing cable must be fastened with bolts and the spacer must be attached to one end while moving between the cable holding parts such as utility poles with a work vehicle at a high place. In addition, since the state where the birds are prevented from flying is obtained by passing and supporting the linear body on the spacer arranged at an appropriate interval on the cable, the operation becomes complicated.

  An object of the present invention is to provide a method for stretching a wire body for preventing birds from flying in an existing cable, which can simplify the operation as compared with the conventional example. In addition, it is desirable to provide a spacer suitable for obtaining a bird flying prevention device that reliably holds the distance between the existing cable and the teg or other linear body.

  An operation for attaching a spacer to one end of a Tegs or other linear body, and a cable laid between a pair of cable retaining portions composed of a power pole or the like, on one of the cable retaining portions side, a ring at the other end of the spacer A required number of the spacers whose one ends are connected to each other by the linear body are arranged along the cable by loosely fitting a cylindrical connection piece on the outside of the cable and suspending the spacer on the cable. Then, the spacer is moved from the one side of the cable retaining portion toward the other side of the cable retaining portion to expand the spacer with a predetermined interval between the cable retaining portions. The linear body secured to one cable retaining portion side is pulled from the other cable retaining portion side and arranged immediately above the cable. Than it is stretched birds flying preventing linear body Buru.

  Then, birds fly on the cable between the existing cable such as an optical cable and the tegs or other linear body for preventing the birds from flying, and the spacer used for the tensioning method is arranged on the cable. A spacer that keeps the separation width incapable of being provided, and is provided with a cylindrical connecting piece that is assembled with the linear body at one end and loosely fitted outside the cable at the other end and assembled to the cable. It is what.

  According to the present invention, it is possible to easily obtain a device that can prevent a bird from flying and staying by arranging a linear body on an existing cable, and to be used for the device. Since the spacer is movably combined with the existing cable without being fixed to the existing cable, it is suitable for obtaining a cable device that prevents birds from flying.

FIG. 6 is a partial perspective view of FIG. 5.

An apparatus for preventing birds from flying on a cable (generally, a retractable cable), such as an optical cable, according to the present invention, is placed at an appropriate interval directly above a cable c constructed between cable retaining portions P ₁ and P ₂ such as utility poles. A linear body a such as a teg is arranged to prevent birds from flying (staying) on the cable c due to the presence of the linear body a, so as to prevent so-called bird damage caused by feces and others. In order to keep the separation distance between the cable c and the linear body a constant, the spacer A is provided between the two to obtain the cable bird flight prevention apparatus according to the embodiment (see FIG. 5).

  As shown in FIG. 8, the spacer A is a spacer main body 1 having a substantially T-shaped cross section composed of left and right side pieces 1a, 1b and a central piece 1c arranged in the center between the side pieces 1a, 1b. It is constituted by a vertically long synthetic resin body provided with an assembling means 2 at one end and a cylindrical connecting piece 3 at the other end.

  The assembling means 2 includes left and right engaging pieces 4a, 4b and a central engaging portion in which the respective pieces 1a, 1b, 1c of the spacer main body 1 are extended from the other end of the spacer A toward one end. The part 4c is provided with slits 5, 6, and 7, and the linear body a is engaged and assembled with the slits 5, 6, and 7. And the slit 5 of the left latching piece 4a provided on the extension of the left side piece 1a and the slit 6 of the right latching piece 4b provided on the extension of the right side piece 1b are the respective pieces 4a, 4b. The slit 7 of the central locking piece 4c opens at the tip of the piece 4c and extends in the one end direction from the other end. The rear ends 5a and 6a of the slits 5 and 6 of the stopper pieces 4a and 4b are in the direction of both ends (the one end and the other end) of the slit 7 of the central locking piece 4c and both ends (the one end and the other end). The positions are shifted in the orthogonal direction. As described above, the connecting piece 3 is installed at the one end of the spacer main body 1 and has a substantially rectangular tube shape in which the both end direction sides of the spacer main body 1 are on the long diameter side. A slit is provided on one side and an opening 8 is provided for introducing the cable c into the connecting piece 3 and fitting it loosely.

  The introduction port 8 provided in the connection piece 3 is composed of one end 3a of the connection piece 3 and the other end 3b that protrudes and overlaps with the one end 3a in a bowl shape, and between the both ends 3a and 3b. Is a curved path extending from the outside of the cylindrical connection piece 3 to the inside of the connection piece 3, so that the cable c introduced into the connection piece 3 and loosely fitted is moved (connected) through the introduction port 8 to the outside of the connection piece 3. The cable c is prevented from falling off from the piece 3.

Then, _{one of} the existing cables c (illustrated is an optical cable for communication, but there is no problem with the power cable) constructed between a pair of cable retaining portions P ₁ and P ₂ constituted by a power pole or the like. In the retaining portion P ₁ , a required number of spacers A,... Are assembled and arranged on the cable c in the connection piece 3, and then, one retaining portion from the preceding spacer A on the other retaining portion P ₂ side. An existing cable c is assembled by assembling the linear body a by the assembling means 2 sequentially toward the rear spacer A on the P ₁ side (may be from one retaining portion P ₁ to the other retaining portion P ₂ ). one of the anchoring portion P ₁ side, one end side via the linear member a are combined with each other, the required number of spacer a to the other end is assembled to the cable c, ... along the cable c of They are arranged side by side.

In addition, the length of the linear body a is preset to a length corresponding to the distance between the retaining portions P ₁ and P ₂ . Further, the assembling work of the spacer A with the cable c and the assembling work of the linear body a may be performed in succession, and it is not necessary to stick to the order of the steps.

Then, the linear body connector 9, the coil spring 10, and the locking clip 11 are sequentially connected to both ends of the linear body a (this connection operation may be performed in a timely manner). the stop clip 11, the in the one of the retention portion is hooked to the anchor member 12 having the P ₁ (locked) state, the linear member a, the tip of the other anchor portion P ₂ side other anchoring portion is moved to the P ₂ side (this movement, or using aerial work platforms, or move with a long rod from the ground, may be freely selected), the said other anchor portion P _In FIG. ₂ , when the linear body a is pulled (FIG. 4), the linear body a that is suspended by the cable c along the slack of the cable c via the spacers A,. Is applied to the curved state due to the slack of the cable c. An attempt is made to make a straight line between the retaining portions P ₁ and P ₂ , and as a result, it moves upward from the cable c.

  With the movement of the linear body a, the other end side of the spacer A, one end of which is fastened to the linear body a by the assembling means 2, is loosely fitted to the outside of the cable c in the connection piece 3. The spacer A is substantially at the original height position, and the reverse movement of the linear body a from the lower side to the upper side of the cable c is smoothly performed.

Then, the linear member a spacer A, after which arranged on the cable c ... through, the locking clip 11 of the tip side of the linear member a to anchoring member 12 of the other cable anchoring portion P ₂ By locking, it is possible to obtain an overhead state of the cable c having a bird damage prevention function in which the linear body a is always arranged on the cable c with a predetermined interval by the spacer A. (FIG. 5).

  The linear body a (generally composed of Tegs and wires, but if it has the same function as these, for example, there is no problem even with a simple resin string) and the spacer A are each slit of the assembly means 2 5, 6, and 7 are assembled by engaging the linear body a up to the position where it contacts the inner ends 5 a, 6 a, and 7 a. In this assembled state, the slits 5 and 6 on the left and right sides and the central slit 7 are in a relationship in which the opposite sides are opened, and as shown in the figure, the positions are shifted back and forth, and in use, the slits are linear. Since the slits 5 and 6 (the back ends 5a and 6a thereof) on both sides are hooked on the body a or the slit 7 (the back end 7a thereof) is hooked on the linear body a, the linear body a and the spacer A will not leave each other. In short, when the tension is applied by pulling the linear body a, the slits 5, 6 and 7 do not have to be separated from the linear body a. When the tension state is maintained, the cable c If the load is heavy, the load from the spacer A side, which is loaded through the connecting piece 3 part, is applied to the linear body a in the central slit 7, that is, the spacer piece 4 c. The linear body a for preventing birds from flying is more reliably located on the cable c and exhibits a bird damage prevention effect. Even when the cable c is light like an optical cable, it does not fall off due to the cylindrical shape of the connection piece 3, and the bird flying prevention interval between the cable c and the linear body a is maintained.

  For the cable c and the spacer A, the ring-shaped connection piece 3 provided in the spacer A is forcibly connected to the introduction port 8 provided in the connection piece 3 (one end piece 3a and the other end portion of the connection piece 3). (Using the elasticity of the piece 3b), the cable A is assembled with each other so as to be loosely fitted on the outside of the cable c, and the spacer A is freely movable around the cable c which is the stationary (fixed) side. It is assembled to rotate.

  Then, the assembly operation of the cable c and the spacer A and the assembly operation of the linear body a and the spacer A are appropriately performed, and as described above, the rear end of the spacer A is on the one retaining portion side. The required number of the spacers A,... Connected to each other by the linear body a are arranged side by side along the cable c, and then from the one cable retaining portion side to the other cable retaining portion side direction. The spacers A are moved between the cable holding portions so that the spacers A are spread at a required interval, and then the linear body a whose end is fixed to the one cable holding portion side is connected to the other cable. By pulling from the retaining portion side and arranging directly above the cable, the existing cable is prevented from flying.

In the embodiment, the assembling means 2 provided in the spacer A is constituted by the slits 5, 6 and 7 and their arrangement relationship. In short, after assembling the spacer A to the linear body a, It is sufficient that the spacer A does not fall off from the linear body a in the state of preventing the birds from flying due to the extension work between the cable holding portions P ₁ and P ₂ of the linear body a and the presence of the linear body a after the work. Therefore, it is not necessary to limit to the structure of the embodiment.

  Further, the connecting piece 3 has a rectangular rectangular tube shape, but there is no problem even if it is cylindrical in shape, and the introduction port 8 provided in the connecting piece 3 is not necessarily limited to the structure of the embodiment. An external fitting operation can be performed on the linear body a, and after the external fitting, the linear body a need only be removed from the connection piece 3 through the introduction port 8. The separation distance between the connecting piece 3 and the assembling means 2 appears as a separation distance between the linear body a and the cable c, and if the distance is too long, the birds can avoid the linear body a and the cable c Be careful because you can fly up.

The attachment (fastening) means for the cable holding portions P ₁ and P ₂ of the end of the linear body a need not be limited to the structure of the embodiment, but the coil spring 10 is attached to the end portion as in the embodiment. If provided, when wind pressure acts on the device (linear body a), the coil spring 10 extends and absorbs the pressure, so that cutting due to the wind pressure of the linear body a can be prevented.
