METHOD OF REMOVING DEPOSIT, MAINLY FROM ROOFS, PREVENTING ITS ACCUMULATION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2021 - IPC E04D13/76 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely, to method of removing deposit, mainly from roofs, and device for its implementation. Method comprises forming an air stream using natural wind energy, capturing air flow on the windward side of the roof and directing the incident airflow into the convergent channel, the inlet part connecting the windward side of the roof, with windward part of which is formed by top and bottom aprons, profiled by Bernouilli lemniscate, air flow direction is changed, air flow is changed over the channel and expanding flat jet is moved to the channel moving along the roof surface, and deposits are blown off. Lower wall of the channel at the beginning is formed by a lower apron, and then - by the surface of the roof element. Upper wall of the channel at the beginning is formed by an upper peak, and then - by the umbrella surface. On the windward side of the roof there are lower and upper aprons shaped along the Bernouilli lemniscate, which form the inlet part of the channel and are the lower and upper walls of the channel.

EFFECT: reduced power consumption.
