Embodiment Construction
[0043] The basic idea of the present invention is to combine the self-propagating combustion reaction and the deicing technology to safely and efficiently deicing the cable.
[0044] In order to deepen the understanding of the present invention, the present invention will be further described with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.
[0045] A self-propagating reaction-based cable deicing equipment includes a power part, a self-propagating reaction part, a control part and a frame;
[0046] The power part includes a cable roller set 8, which is arranged coaxially with the pulley set 10. The pulley far away from the self-propagating reaction part of the pulley set 10 is coaxial with the worm gear 9. The worm gear 9 cooperates with the worm 18 and is driven by the motor 12 to rotate. The motor is powered by the battery...

The invention relates to a self-propagating reaction and cable deicing technology, in particular to a cable deicing device based on the self-propagating reaction. In the deicing process, the self-propagating chemical reaction is utilized for releasing heat, the phenomenon that mechanical energy is used for cutting ice layers is avoided, and no additional external heat source is needed. The deicing speed can be adjusted by controlling self-propagating reaction powder ingredients. By means of heating deicing, damage caused by mechanical deicing to cables is reduced. High-temperature hot air produced by the self-propagating reaction and heat radiation of a follow-up high-temperature mold are used for deicing, the efficiency is high, and the effect is good. The device is easy to operate, convenient to use, safe and reliable. A self-propagating device is low in weight, and meets the requirement for cable loads. The reaction process is environmentally friendly and discharges no pollutant. An automatic device is utilized for carrying the self-propagating device so that self-propagating device can reach the dangerous area or the area which workers cannot reach easily. A self-propagating powder bin is separated from a high-temperature-resisting graphite mold, and can be directly replaced after being used. By combining the self-propagating reaction and the deicing technology, the overall deicing efficiency is improved, continuous energy supply is not needed once ignition is achieved, and therefore energy consumption is small. The device is simple, the workers do not need to reach the working site, and operation is safe.
Description
Technical field [0001] The invention relates to a self-propagating reaction and cable deicing technology, in particular to a cable deicing equipment based on a self-propagating reaction. Background technique [0002] In most areas of our country, there may be icy snow or freezing rain every year. In this weather environment, the surface of high-voltage cables used for power transmission will freeze. When the thickness of the icing on the cable surface exceeds the design standard, It will cause the cable to bear excessive pressure, and then cause serious accidents such as pulling down the high-voltage transmission pole, and then interrupt the power supply. Many of the existing high-voltage transmission lines are laid in the wild with inaccessible people and harsh geographical environment, which leads to the difficulty and long duration of repairing the accident cable when the above-mentioned accident occurs. [0003] The existing cable deicing methods are: [0004] For DC ice meltin...
