PNEUMATIC ANTI-ICING SYSTEM FOR LIQUIDATION OF ICICLES ON BUILDING ROOFS Russian patent published in 2014 - IPC E04D13/76 

FIELD: construction.

SUBSTANCE: anti-icing system comprises a tight protector from elastomer or rubber-reinforced material as capable of connection to a source of compressed air - a compressor. The protector is made as flat from a rolled web folded in two in longitudinal direction with one side overlapping, which at all sides freely covers a volume wide-meshed net. A tube with nozzles at the ends is stretched via the protector, being attached to the edge of the net at the overlapping side. A part of the tube in the protector is perforated by holes, and the outlet of the compressed air source via the first outlet of the tee connected to its outlet and the hose is connected to the inlet nozzle of the tube, the outlet nozzle of which is closed with a plug. The second outlet of the tee is connected to the inlet of the normally opened electric valve, the winding of which and the winding of the compressor electric motor via a dipole switch are in parallel connected to a low-voltage source of power supply and to a socket for connection to a system of autonomous low-voltage portable source of power supply.

EFFECT: increased operational reliability of a roof.
