Abstract
Provided is an anti-twist absorber which enables the shape of the accumulated snow to be uneven and inhibits the lift force exerted upon an overhead transmission line and a ground line from wind. The anti-twist absorber comprises a hoop (40) installed upon an armed lever (60), with the armed lever (60) installed upon the overhead transmission line and/or the ground line (70), a movable holder (50) which, arranged upon half of the hoop (40) installed upon an armed lever (60), presses the hoop (40) to armed lever (60) to hold the hoop, and a holder part (30) which consists of a rotary movable part (32) and an embedded part (34). The rotary movable part (32) and the hoop (40) are provided with stop dogs (36, 42) which can stop the rotation at the required turn angle. The rotary movable part (32) is installed upon the other half of the loop (40). The embedded part (34) is inserted with a pole (20), with the embedded part (34) in embedded connection with the pole (20). Both ends of the pole (20) are embedded with a heavy bob (10).
Description
Technical field
The present invention relates to be used for make that snow is difficult to be attached to the anti-distortion vibration isolator (damper) of overhead transmission line and ground wire, more specifically, relate to and a kind ofly make that the accumulated snow shape is inhomogeneous and suppress the suffered anti-distortion vibration isolator of this electric wire from the lift of wind.
Background technology
When on overhead transmission line and ground wire, adhering to snow, this electric wire is distorted because of the moment that snow produces, and around electric wire, accumulated snow increases with barrel shape, because faults such as broken string can take place overweight accumulated snow.For the bending that suppresses this electric wire and prevent overweight accumulated snow, anti-distortion vibration isolator has been installed on overhead transmission line and ground wire.The electric wire that anti-distortion vibration isolator is installed can not be distorted, so accumulated snow increases easily in one direction.If this accumulated snow that increases is by wind, then electric wire receives lift, and galloping (galloping) takes place sometimes.
Fig. 3 is the structure chart that the structure of existing anti-distortion vibration isolator is shown.In Fig. 3, existing anti-distortion vibration isolator 200 is one distolateral gripper portion 80, the armed lever 60 that is installed on overhead transmission line/ground wire 70 is controlled, the other end of gripper portion 80 chimeric weight 10.Overhead transmission line/the ground wire 70 that has added vibration isolator is difficult to be distorted, and accumulated snow increases easily in one direction, becomes the reason of electric wire generation galloping.
In patent documentation 1, put down in writing following content, that is, anti-distortion vibration isolator comprises: arm is fixed on the clamper that is used for controlling power transmission line; Hemisphere is located at the front end of this arm; Elastomer is configured to this hemispheroidal bottom surface of contact; And has a weight that is used to accommodate this elastomer and hemispheroidal cavity.Wherein, elastomer is in compressive state in the cavity of weight.

Summary of the invention
The present invention proposes in order to solve such technical problem, and its purpose is to provide a kind of and makes that the accumulated snow shape is inhomogeneous and suppress overhead transmission line and ground wire is suffered from the anti-distortion vibration isolator of the lift of wind.
Anti-distortion vibration isolator of the present invention has: hoop, be installed on the armed lever, and this armed lever is installed on overhead transmission line and/or the ground wire; Movable clamper on half part that is installed on the hoop on the armed lever, is crimped on above-mentioned hoop on the above-mentioned armed lever and controls above-mentioned hoop; And gripper portion; Possess rotation movable part and fitting portion; Above-mentioned rotation movable part and above-mentioned hoop have the block that when the corner of regulation, rotation is stopped; Above-mentioned rotation movable part is installed on second half part of above-mentioned hoop; It is chimeric in above-mentioned fitting portion, to have inserted bar and above-mentioned fitting portion and above-mentioned bar, the chimeric weight at the two ends of above-mentioned bar.
The effect of invention is following:
According to the present invention, can provide a kind of and make that the accumulated snow shape is inhomogeneous and suppress overhead transmission line and ground wire is suffered from the anti-distortion vibration isolator of the lift of wind.

Embodiment
Utilize description of drawings execution mode of the present invention.Fig. 1 is the structure chart that the structure of anti-distortion vibration isolator of the present invention is shown.In Fig. 1, movable clamper 50 on half part that is installed on the hoop 40 on the armed lever 60, will bind round 40 and be crimped on the armed lever 60 and control this hoop 40, and this armed lever 60 is installed on overhead transmission line and/or the ground wire 70.The rotation movable part 32 of the gripper portion 30 of anti-distortion vibration isolator 100 of the present invention is installed on second half part of hoop 40.In addition, it is chimeric with bar 20 on fitting portion 34, to have inserted bar 20 and fitting portion 34, the chimeric weight 1 at the two ends of bar 20.Rotation movable part 32 and hoop 40 have the block 36,45 that when corner illustrated in fig. 2, in regulation, rotation is stopped respectively.Also can omit armed lever 60.
The snow that adheres on overhead transmission line/ground wire 70 becomes the moment that makes the electric wire distortion, thereby produces distortion, and accumulated snow increases on the direction corresponding to corner.Below, this is elaborated.
Fig. 2 is the structure chart that the structure of hoop of the present invention and rotation movable part is shown.In Fig. 2, hoop 40 has makes the block 45 that stops of rotation when predetermined angular, and this hoop 40 is clamped the armed lever 60 Fig. 1 from both sides, by movable this hoop 40 of clamper 50 crimping and control this hoop 40.Rotation movable part 32 hinge-type ground open and close, and side has the block 36 that when the corner of regulation, rotation is stopped within it, and this rotation movable part 32 is installed on the hoop 40 among Fig. 1.
In addition, in Fig. 1, because the distortion moment that accumulated snow causes, overhead transmission line/ground wire 70 is rotated, and the block 45 of the hoop 40 among Fig. 2 turns to the position that is in contact with one another with the block 36 of rotation movable part 32 always.Therefore, on overhead transmission line/ground wire 70, accumulated snow increases on the direction corresponding to corner.Therefore, the phenomenon that accumulated snow only increases in one direction can not take place, can suppress the phenomenon that galloping takes place because of wind for overhead transmission line/ground wire 70 behind the accumulated snow.Therefore, can provide a kind of and can make that the accumulated snow shape is inhomogeneous, suppress the suffered lift of overhead transmission line and ground wire from wind, suppress the anti-distortion vibration isolator of galloping phenomenon.
