Abstract
Description
Technical Field
[0001] The invention relates to a stress wave generating mechanism, in particular to a stress wave generating mechanism for splitting a conductor. Background Art
[0002] At present, mechanical deicing is mainly used for high-voltage lines, and the most mature method is blank bullet mechanical deicing. This method uses the large amount of energy generated instantly by blank bullets to impact the ice-covered line, causing the ice-covered line to generate stress waves that propagate along the ice-covered line. The ice on the line produces high strain and falls off under the action of high-frequency vibration waves. As the lateral waves propagate, the ice on the line breaks into small pieces and falls off. However, this method has its inherent disadvantages, that is, the blank bullet is suspended on a single split conductor by a traction rope. During the collision between the projectile and the conductor, the conductor will produce a large displacement in the direction of the collision. The generation of this displacement will cause the collision time between the projectile and the conductor to become longer, making the strain rate of the stress wave generated on the conductor lower, which has a greater impact on the deicing effect.
[0003] If a support surface similar to the earth can be provided for the split conductor, so that its displacement is limited when the projectile collides with the conductor, the action time of the collision between the high-speed projectile and the conductor can be effectively reduced, and a stress wave with a higher strain rate can be generated on the conductor, thereby greatly improving the deicing effect of the mechanical deicing device; in addition, this structure is also conducive to designing a mechanism similar to the split conductor spacer, which can provide a good foundation for the realization of the intelligent deicing spacer. Therefore, those skilled in the art provide a stress wave generating mechanism for a split conductor to solve the problems raised in the above background technology. Summary of the invention
[0004] The object of the present invention is to provide a stress wave generating mechanism for splitting a conductor, so as to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above object, the present invention provides the following technical solutions:
[0006] A stress wave generating mechanism for splitting a conductor comprises a mechanism body, wherein the mechanism body is provided with a conductor connecting arm, a control unit is provided in the middle of the conductor connecting arm; a left projectile accelerating mechanism and a right projectile accelerating mechanism are respectively provided on the left and right sides of the control unit and located inside the conductor connecting arm.
[0007] As a further solution of the present invention: the left projectile acceleration mechanism and the right projectile acceleration mechanism both use an electromagnetic repulsion mechanism to accelerate.
[0008] As a further solution of the present invention: the left end of the wire connecting arm is connected to a left wire clamp; the right end of the wire connecting arm is connected to a right wire clamp.
[0009] As a further solution of the present invention: a wire hole is provided between the left wire clamp and the right wire clamp, and an arc structure that can be rotated to open is provided on the side away from the wire connecting arm. When the arc structure is opened, the wire can be placed in the wire hole and then rotated to close.
[0010] Method of using the stress wave generating mechanism for splitting the conductor: when the conductor needs to be de-iced, the conductor is clamped into the conductor hole of the conductor clamp, and then the control unit synchronously starts the two sets of projectile acceleration mechanisms, and causes the two sets of projectiles to collide with the conductors in their respective directions at the same time; due to the mutual restraint between the two conductors, the conductor cannot produce a large displacement in the direction of its collision during the collision, thereby shortening the collision action time between the projectile and the conductor, causing a stress wave with a higher strain rate in the conductor, thereby improving the de-icing effect.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. When it is necessary to de-ice the wire, insert the wire into the wire hole of the wire clamp, and then the control unit synchronously starts the two sets of projectile acceleration mechanisms, and makes the two sets of projectiles collide with the wires in their respective directions at the same time; due to the mutual restraint between the two wires, the wire cannot produce a large displacement in the direction of its collision during the collision, thereby shortening the collision time between the projectile and the wire, so that a stress wave with a higher strain rate is generated in the wire, thereby improving the de-icing effect.
[0013] 2. The stress wave generating mechanism of the split conductor provided by the present invention allows the two relative conductors to restrain each other, thereby limiting the displacement of the conductors during the de-icing process, reducing the action time of the collision between the high-speed projectile and the conductor, and generating stress waves with higher strain rates on the conductors, thereby greatly improving the de-icing effect of the mechanical de-icing device.
