UHF ANTI-ICING APPARATUS Russian patent published in 2021 - IPC E04D13/76 

FIELD: building.

SUBSTANCE: invention relates to the field of building, in particular, to anti-icing apparatuses with UHF heating. The UHF anti-icing apparatus includes a first power source, a heating element, a power supply cable, a control unit connected by the first arm to the outputs of the temperature, snow presence and water presence sensors, is equipped with a UHF generator with reconfigurable power, a second power source, an activation-deactivation unit. The heating element is made in the form of a dielectric waveguide fixed along the edge of the slope of a metal roof with a gap from the surface thereof. The output of the UHF generator is connected with the dielectric waveguide by means of the power supply cable, the output of the first power source is connected with the first arm of the activation-deactivation unit and through the second power source with the sensors and the second arm of the control unit. The second arm of the activation-deactivation unit is connected to the power supply input of the UHF generator, the third arm of the control unit is connected with the third arm of the activation-deactivation unit.

EFFECT: increased operational security of the roof.
