FIELD: construction.
SUBSTANCE: device comprises a vehicle with a lift and a sliding rod with a working element in the form of a striker fixed on it and connected to a magnetic core of a solenoid. The solenoid is made with the possibility to adjust its capacity. Frequency of the solenoid with the help of a feedback sensor installed on the working element after a series of strikes at eaves is automatically adjusted for its internal frequency of oscillations, which varies depending on the extent of damage and adhesion of ice formations on eaves. At the same time on the working element there is a microwave emitter, electromagnetic waves of which are directed to the area of the strike, and sufficient number of strikes in the series and their capacity are defined visually by variation of the ice damage extent.
EFFECT: improved quality of building roof eaves cleaning from icicles.
