Cable spacer with high-altitude cable snow-removing, dust-removing and bird-repelling functions

Abstract

The invention discloses a cable spacer with high-altitude cable snow-removing, dust-removing and bird-repelling functions. The cable spacer comprises a supporting body with at least two supporting arms and clamping bodies arranged at the tail ends of the supporting arms of the supporting body and used for clamping a cable. Each clamping body comprises a structural body, and an inverse piezoelectric vibration mechanism for making contact with a high-altitude cable and conducting high-frequency mechanical waves or sound waves to the high-altitude cable and an inductance mechanism for obtaining induction current through an induction magnetic field of the high-altitude cable are integrated in the structural body. The inductance mechanism supplies power to the inverse piezoelectric vibration mechanism, the structural characteristics of the cable spacer are utilized, electric energy transmitted by a high-voltage transmission line is utilized, the functions of removing snow, removing dust andrepelling birds are realized by acquiring a small amount of energy in a non-contact manner, the cable spacer has operability, safety, remote control or automatic control performance, can be synchronously installed along with installation of the spacer, does not need additional installation operation, and is low in cost, the service life of the high-altitude cable is can effectively prolonged, anddamage of adverse external environment to the high-altitude cable is reduced.

Description

technical field [0001] The invention belongs to the technical field of cable maintenance, and in particular relates to a cable spacer with the functions of removing snow, dust, and birds for high-altitude cables. Background technique [0002] High-altitude cables carry the heavy responsibility of long-distance power transmission. They are blood vessels for economic development, industrial production, and residential electricity consumption. They cannot be lost. Most of the high-altitude cables are located in remote areas. Therefore, for high-altitude cables, extreme care is required to avoid damage to the cables due to external adverse conditions. The existing high-altitude cables have high erection heights and high voltages, and their quality is required by national standards, which can basically meet the requirements of service life. , and is less considered to be damaged, but there are still some factors in nature that will damage it, reduce its service life, and may even...

[0002] High-altitude cables carry the heavy responsibility of long-distance power transmission. They are blood vessels for economic development, industrial production, and residential electricity consumption. They cannot be lost. Most of the high-altitude cables are located in remote areas. Therefore, for high-altitude cables, extreme care is required to avoid damage to the cables due to external adverse conditions. The existing high-altitude cables have high erection heights and high voltages, and their quality is required by national standards, which can basically meet the requirements of service life. , and is less considered to be damaged, but there are still some factors in nature that will damage it, reduce its service life, and may even cause sudden accidents and cause greater losses. Large, the cable between the two poles is long, and the extra weight of the snow on the cable is a great burden; another example is the birds staying on the cable or cable pylon, their sharp claws are easy to cause damage to the surface of the cable, even a relatively small wound, It is also easy to aggravate corrosion in the external environment for a long time and reduce the life of the cable; the feces excreted by birds are conductors and are corrosive, which will also cause damage to cables or cable towers or cause accidents; The cable with a good surface quality has little effect, but today a lot of dust contains acidic substances, which can easily corrode the cable when combined with rainwater. If there is a wound on the cable surface, the dust will accumulate in the wound and further aggravate the corrosion of the wound; existing There is no effective means of snow removal and dust removal in the technology, and bird-repelling methods generally use bird-proof metal thorns, but on the one hand, the installation cost is high, and on the other hand, it will cause greater damage to birds, so it is not a good method
