Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is designed to prevent flash faults in power transmission line systems that occur when small flying animals such as birds and flying squirrels fly into insulators on steel towers and utility poles that support power transmission lines. This device relates to a bird-animal damage prevention device for power transmission lines to prevent accidents, and has been improved so that it can be easily attached and detached, making it easier to perform one task, especially during maintenance work.

[Prior Art] Conventionally, as shown in FIG. 11, it is known that a prevention device such as a rod 14a is attached directly to the insulator A. Since the rod 14a gets in the way during construction, etc., it is necessary to cut off the tightening band C, remove the rod 14a, and then wrap the tightening band C around it in order to reinstall the rod 14a after maintenance work. There is a problem with Kaname.

Therefore, some improvements have been made in which the rod 14a is removably attached to the tightening band C of the prevention device. The rod body 14a is blown off and falls off due to the agitation, and is no longer able to fulfill its intended role.

In addition, as shown in Fig. 12, there is a prevention device in which a rod 14a is fixed to the side of the insulator A of the mounting arm B, and the prevention device is tightened and fixed with a tightening band C, but this prevents maintenance work. At that time, the tightening band C must be separated and removed, and it is time-consuming to reattach and fix it after the construction is completed, and it is also dangerous because the work must be done at height.

[Problems to be solved by the invention] A part of the bird and animal damage prevention device can be easily removed during maintenance work, etc., and can be easily and reliably fixed after the work is completed, making the work easier. , and to ensure safe work.

[Means for solving the problem] The barricade consists of a fixture that is attached and fixed to an arm, etc. installed on a steel tower, telephone pole, etc. to insulate and support the power transmission line, and a barricade body that is detachably attached to the fixture, A large number of insulating rods are fixed to the upper surface of the barricade body in a row.

[The insulating rods standing on the barricade body, which is removably attached to a fixture fixed to the working core arm, etc., prevent birds and beasts from flying in. In addition, when carrying out maintenance work, etc., the barricade body can be removed along with the fixtures, making it easier to carry out the work.
The barricade body can be safely installed and the barricade body can be easily installed and fixed again after the construction is completed.

[Example] In the figure, reference numeral 1 denotes a baseplate-like fixture that is mounted on the mounting arm B of the insulator A, and insertion portions 2, 2 for tightening bands c, c are provided at both left and right ends, and each The tightening bands c, c inserted through the insertion portion 2.2 are made to go around the mounting arm B and are fixedly attached. A circular cavity 3 is provided in the center of the upper surface of the fixture l, and a cylindrical shaft part 4 is made to protrude upright from the center of the cavity 3. Further, the fixture 1 is provided with screw holes 5.5 that penetrate in the vertical direction at opposite corner portions outside the cavity 3.

Reference numeral 6 denotes an intermediate member superimposed on the upper surface of the fixture 1, which communicates with the cavity 3 in the center thereof, and has a circular through hole 7 with a diameter smaller than that of the cavity 3 penetrated therethrough, and communicates with the through hole 7. Slot holes 8, 8 are provided opposite each other.

Furthermore, spring insertion holes 9, 9 communicating with the screw holes 5, 5 of the fixture l are passed through the intermediate member 6, and a coil spring 10.1 is inserted into the intermediate member 6.
0 is attached, and a sphere 11 is mounted on each coil spring 10.10.
．． 11 with its upper end protruding from the upper surface of the intermediate member 6 and being unremovably loaded into the spring insertion holes 9, 9, and the lower end of each coil spring 10.10 with the screw hole 5 of the fixture 1.
, 5 with a stopper 12. tz is screwed and supported, and the sphere 11.11 is elastically biased.

Reference numeral 13 denotes a barricade main body on which a large number of FRP insulating rods 14 are fixed in a straight line, and the barricade main body 13
A cylindrical protrusion 15 that fits into the through hole 7 of the intermediate member 6 is provided at the center of the lower surface. At the tip of the protruding part 15, protrusions 16 and 16 that fit into the slots 8 and 8 provided in the intermediate member 6 are provided in succession, and furthermore, the shaft part 4 provided in the fixture l is fitted in the center of the protruding part 15. A shaft hole 17 for matching is provided. Furthermore, the lower surface of the barricade body 13 has a recessed hole it, 1g, into which a part of the sphere 11.11 protruding from the upper surface of the intermediate member 6 is fitted.
The bird and animal damage prevention device for power transmission lines of the present invention, which is constructed as shown in FIG. A fixture 1 with an overlapping intermediate member 6 is attached and fixed to a portion of the arm B near the insulator A via a tightening band C1C. Then, the protrusion 15 and projection 16.16 of the barricade body 13 are inserted into the through hole 7 and groove 8.8 of the intermediate member 6 and pressed down, with the projection 16.16 facing the cavity 3 of the fixture l. By rotating the barricade main body 13, the upper surface of the protrusion 16.degree. 16 is locked with the bottom surface of the intermediate member 6, and the mounting tool 1. The intermediate member 6 and the main part of the barricade body 13 are irremovably connected. In this state, the barricade body 13 is held by fitting the sphere 11.11, which partially projects from the upper surface of the intermediate member 6, into the recessed hole 18.18, and by the elastic bias of the coil spring 10.

Then, during maintenance work, etc., the barricade body 13 is rotated with strong force against the elastic bias of the coil spring 10.10, and the protrusion 15 and the protrusion 16. It can be easily removed by pulling it out from the slots 8, 8. Moreover, once the construction is completed, it can be reinstalled using the procedure described above, and both installation and removal can be done easily.

In addition, a large number of F
By fixing the edge rods 14 made of RP in a radial manner as shown in the figure, it is possible to widely prevent birds and animals from trying to rest on the mounting arm or coming into contact with the insulator A.

[Effects of the Invention] As described above, the bird and animal damage prevention device for power transmission lines of the present invention attaches a support to an insulator mounting arm provided on a steel tower, utility pole, etc. that supports a power transmission line, and attaches a support to this support. On the other hand, since the barricade body is constructed so that the barricade body, which has edge rods fixed in a row, can be attached and detached, it is possible to temporarily remove the barricade body and work safely when carrying out maintenance work on the power transmission system, etc. 6 In addition, since the prevention device of the present invention is designed to removably attach and fix the barricade body to the attachment device which is pre-swaged and attached to the attachment arm, the installation workability is also excellent, and it is possible to prevent the device from coming into contact with flying objects. It will not fall off or fall off due to the wind.
The purpose of preventing damage to birds and animals can be fully achieved.
