[0007] The utility model has the advantages that when there is no snowfall, the capacitance value of the electric capacity sensor remains stable, when snow falls on the sensing surface of the electric capacity sensor, the capacitance value will change because the dielectric constant of snow is different from that of air, the more snow accumulates, the greater the change in capacitance value, and the accumulation degree of snow can be determined by detecting the change in capacitance value; the temperature control system automatically controls the switching of the heat tracing cable according to the preset temperature and the capacitance threshold value, so that the heating is automatically started when there is snow accumulation and automatically turned off after melting, and automatic snow melting is realized to prevent the occurrence of ice column injury.

[0008] Scheme two, which is a preferred embodiment of the basic scheme, the roof is an inclined roof, and the edge of the roof is fixedly connected with a fence. After snow melts, the corrugations of the color steel sheet form water channels, and the water flows downward along the slope of the roof. The groove formed by the fence and the eave flows to both ends of the roof, so that the water is discharged from the corners and avoids falling on pedestrians from the eave.

[0009] Scheme three, which is a preferred embodiment of the basic scheme, a water guide groove is arranged at the corner of the fence. The water guide groove is inclined downward to guide the water flow to the outside of the roof to prevent the water flow from flowing along the edge of the roof to the heat tracing cable.

[0010] Scheme four, which is a preferred embodiment of the basic scheme, a wire slot is fixedly connected below the roof, and the heat tracing cable is arranged in the wire slot. The wire slot supports the heat tracing cable and protects the heat tracing cable and circuit from adverse weather.

[0011] Scheme five, which is a preferred embodiment of the basic scheme, a solar panel is arranged at the top end of the roof, the solar panel is electrically connected with the power supply, and the power supply is a storage battery. The solar panel supplies power to the power supply to save energy. BRIEF DESCRIPTION OF DRAWINGS
