High-temperature electric tracing band

Abstract

The invention discloses a high-temperature electric tracing band, and relates to the technical field of electric tracing bands. The electric tracing band comprises an electric tracing band body, wherein a metal contact is arranged at one end of the electric tracing band body, mounting shells are fixedly connected to the front surface and the back surface of the electric tracing band body, and first through holes are formed in the left side surface and the right side surface of each mounting shell. According to the scheme, the two mounting shells are arranged, the mounting shells and the electric tracing band body are buried in snow, the front-back contact area of the electric tracing band body can be increased through the two mounting shells, and therefore the snow melting capacity is preliminarily improved; by arranging a limiting plate and a heat conduction cover, the left-right contact area of the electric tracing band body is increased; through the arrangement of an extending mechanism, the rotation of the second rotating shaft can relieve the limitation of the baffle block on the extension plate, so that the extension plate extends out of the heat conduction cover under the action of the elastic force of the second spring, the contact area between the electric tracing band body and snow is increased again, the snow melting efficiency of the electric tracing band body is improved, and a large amount of time is saved.

Description

technical field [0001] The invention relates to the field of electric heating cables, in particular to a high-temperature electric heating cable. Background technique [0002] There are many benefits of electric heating cables. Electric heating cables are easy to carry and easy to operate. Electric heating cables are also very safe and will not cause harm to people. The application range of electric heating cables is very wide. It can be used for heating pipelines , can avoid the temperature is too low in winter, the condensation of water in the pipeline, to ensure the normal delivery of water, but also can melt the snow on the roof, ground or some necessary places in winter, to avoid the generation of snow, to ensure the smoothness of the road , when the traditional heating cable melts snow on a large area of ​​snow, the contact area with the snow is small, it cannot melt the snow quickly, the work efficiency is low, and the capacity wastes a lot of time. The traditional el...

[0002] There are many benefits of electric heating cables. Electric heating cables are easy to carry and easy to operate. Electric heating cables are also very safe and will not cause harm to people. The application range of electric heating cables is very wide. It can be used for heating pipelines , can avoid the temperature is too low in winter, the condensation of water in the pipeline, to ensure the normal delivery of water, but also can melt the snow on the roof, ground or some necessary places in winter, to avoid the generation of snow, to ensure the smoothness of the road , when the traditional heating cable melts snow on a large area of ​​snow, the contact area with the snow is small, it cannot melt the snow quickly, the work efficiency is low, and the capacity wastes a lot of time. The traditional electric heating cable needs Only when the metal contact head is energized can the heat be released. The traditional metal contact head is relatively fragile, and it is easy to cause damage when it is exposed to the air for a long time when not in use, thus affecting the normal use of the electric heating cable.
