Description

Technical Field

[0001] The utility model relates to the technical field of roof snow removal, in particular to a roof gutter snow and ice melting device. Background Art

[0002] In light steel structure industrial plant buildings, as the building area increases, the size of the gutters on the steel structure roofs becomes larger and larger. In the cold winter, ice and snow on the roofs gather in the gutters. If they are not melted and discharged in time, it will not only easily clog the gutter drainage pipes, but also easily generate a large load on the roof, affecting the structural safety, and easily cause backflow, which will also cause damage to the internal machinery and equipment.

[0003] However, the current treatment technology for gutter snow and ice melting still has some shortcomings. For example, the current roof gutter snow melting devices generally only lay a simple heating tape or heating cable inside the gutter to use the temperature difference to melt the snow and ice. However, this snow and ice melting method still has the following disadvantages when used: (1) When melting snow and ice, the heating cable and other devices laid at the bottom of the gutter will form a certain obstacle to the flow direction of the melted snow water, and the melted snow water is difficult to discharge quickly; (2) When the siphon rainwater bucket is directly covered by snow, when it freezes, it is easy to cause pipe blockage, resulting in poor drainage during snow and ice melting. Utility Model Content
