Heating film and full-automatic snow removing system for steel structure roof

Abstract

The invention discloses a heating film and a full-automatic snow removing system for a steel structure roof. A PE (Poly Ethylene) or PVC (Poly Vinyl Chloride) heating wire (2) is coiled in two plastic film bodies (1) in an S shape; and two steel cables (3) integrating electric conducting function are arranged at the two sides of the heating wire (2) respectively to form a heating film. When the heating film is adopted for removing snow from the steel structure roof, at least one group of the heating films and a temperature-humidity probe (12) with a certain height are laid on the roof (8); the temperature-humidity probe (12) is electrically connected with an automatic control cabinet (10) which is arranged indoors; a single chip microcomputer (14) is arranged in the automatic control cabinet (10); the heating film is electrically connected with a power supply through a contactor (13); and the contactor (13) is electrically connected with the single chip microcomputer (14). Compared with traditional steel structure plants, the steel structure roof is added with an automatic accumulated-snow melting function and can effectively resist any grade of snow disaster; and a powerful technology guarantee is improved for the safety of steel structure buildings of industrial and mining enterprises.

Description

technical field [0001] The invention relates to a heating film, which includes a PE or PVC heating wire. [0002] The invention also relates to a steel structure house, especially a fully automatic snow removal system for a steel structure roof to ensure the safety of the steel structure building in heavy snow weather. Background technique [0003] At present, PE or PVC heating wires have become a new generation of heating materials due to their characteristics of long-lasting heating temperature, continuous low temperature, strong insulation strength, and high electrothermal conversion rate, and are widely used in the field of low-temperature heating. [0004] Steel structure building is a new type of building that has gradually emerged in recent years and has formed a sufficient scale. It is widely used in the construction of industrial and mining enterprises because of its short construction period, low cost, and strong earthquake resistance. Under normal circumstances, ...

AI Technical Summary

Problems solved by technology

Under normal circumstances, due to the large span of the steel structure building, the roof slope must be relatively slow. In order to prevent the threat of snow to the roof, the specification and model of the roof beam can only be increased, which increases the construction cost.

In addition, because the amount of snowfall is difficult to estimate, even if the specification model of the beam is enlarged, it cannot completely eliminate the danger of being crushed in the event of a severe snow disaster.
