Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibration damping hammer technology, and in particular to an ultra-high voltage corrosion-resistant vibration damping hammer. Background Technology
[0002] High voltage refers to DC voltage levels of ±800 kV and above and AC voltage levels of 1000 kV and above. Vibration dampers are installed to reduce the vibration of conductors caused by wind. High-voltage overhead lines have high pole positions and large spans, so the conductors will vibrate when subjected to wind. The working conditions at the conductor suspension point are most unfavorable when the conductor vibrates. Due to repeated vibrations, the conductors will suffer fatigue failure due to periodic bending. When the span of an overhead line is greater than 120 meters, vibration dampers are generally used for vibration prevention.
[0003] To ensure that vibrations are transmitted to the vibration damper, the damper body and the mounting bracket used to install the damper and the wiring are usually made of metal. Therefore, the gap between the wiring and the mounting bracket due to vibration will cause the position of the vibration damper to change, resulting in a poorer vibration damping effect. At the same time, since the vibration damper needs to be fixed outdoors, it will be subject to corrosion, which not only reduces the quality of the vibration damper itself, but also reduces its service life. Utility Model Content

[0008] This utility model is further configured with two sets of the anti-vibration hammer structure, including: a threaded seat, a nut, an anti-vibration steel cable, and a hammer body; the threaded seat is installed in the mounting hole of the mounting iron base, and the threaded seat is fixed by the nut; one end of the anti-vibration steel cable is installed on the lower wall of the threaded seat, and the hammer body is installed on the other end of the anti-vibration steel cable.

[0022] Reference Figure 1-4 A type of ultra-high voltage corrosion-resistant vibration damper includes: a mounting base 1, an iron top plate structure for mounting is threadedly installed inside the mounting base 1, two sets of anti-slip structures are installed on the side wall of the mounting base 1, two sets of vibration damper structures are installed inside the mounting base 1, a sacrificial structure is installed between the two sets of vibration damper structures, and the mounting base 1 has two mounting holes; the iron top plate structure includes: a mounting screw 2, a bearing 3, and a mounting top plate 4; the mounting screw 2 is threadedly installed inside the mounting base 1, the bearing 3 is fitted onto the outside of the mounting screw 2, and the mounting top plate 4 is installed on the outside of the bearing 3.
[0023] Specifically, the two anti-slip structures include: an anti-slip connecting rod 5, two protective fixing plates 6, and two anti-slip pads 7. The anti-slip connecting rod 5 is installed on the side wall of the mounting base 1, one protective fixing plate 6 is installed on the side wall of the anti-slip connecting rod 5, and the other protective fixing plate 6 is connected to the protective fixing plate 6 by a screw. The two anti-slip pads 7 are respectively installed on the inner side of the two protective fixing plates 6. The anti-slip structure, through the rubber anti-slip pads 7, can ensure that the position of this utility model will not change under line vibration, thereby ensuring the vibration prevention effect.
[0024] Specifically, the two sets of anti-vibration hammer structures include: a threaded seat 8, a nut 9, an anti-vibration steel cable 10, and a hammer body 11; the threaded seat 8 is installed in the mounting hole of the mounting iron seat 1 and is fixed by the nut 9; one end of the anti-vibration steel cable 10 is installed on the lower wall of the threaded seat 8, and the hammer body 11 is installed on the other end of the anti-vibration steel cable 10; the anti-vibration steel cable 10 is L-shaped; the anti-vibration hammer structure can prevent the line from vibrating easily due to external vibrations by its large mass, thus ensuring the safety of the line.
[0025] Specifically, the sacrificial structure includes a sacrificial conductive plate 12, a conductive base 13, and a sacrificial rod 14. The sacrificial conductive plate 12 is fitted onto the outside of the two anti-vibration steel cables 10. The conductive base 13 is installed inside the sacrificial conductive plate 12 by threads. The sacrificial rod 14 is installed on the lower wall of the conductive base 13. The sacrificial rod 14 is made of magnesium metal. The sacrificial structure can prevent oxidation and corrosion from occurring within the sacrificial structure through electrochemical principles, thereby ensuring the integrity of the anti-vibration hammer structure and extending the service life of this utility model to a certain extent.
[0026] Working principle: First, this utility model needs to be installed. The operator installs it at the calculated location on the UHV line. The operator first uses tools to separate the mounting screw 2 and the mounting base 1, and removes the screws securing the two protective fixing plates 6. Then, the operator fixes the mounting base 1 and the two protective fixing plates 6 onto the line. Next, using tools, the protective fixing plates 6 are secured with bolts, and the mounting screw 2 is threaded into the mounting base 1, fixing the mounting top plate 4 and the mounting base 1 to the outside of the line. Simultaneously, the two protective fixing plates 6 clamp the line, and the two anti-slip pads 7 prevent slippage. Two protective fixing plates 6 slide outside the line. When the line shakes, the vibration is transmitted to the anti-vibration steel cable 10 and the hammer body 11 through the mounting iron base 1 and the mounting top plate 4. Since the hammer body 11 has a large mass and a large inertia, it can effectively dampen vibration. When the anti-vibration steel cable 10 and the hammer body 11 are exposed to the atmosphere for a long time, especially in rainy weather, they will oxidize and rust. At this time, the sacrificial rod 14 will supply electrons to them through the sacrificial conductive plate 12 and the conductive base 13 to prevent the anti-vibration steel cable 10 and the hammer body 11 from oxidizing and rusting, so that the anti-vibration steel cable 10 and the hammer body 11 have anti-corrosion function and extend their service life to a certain extent.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
