DEVICE FOR REMOVING ICE FROM BUILDING DRAINAGE PIPES Russian patent published in 2021 - IPC E04D13/76 E04D13/10 E01H5/00 

FIELD: public utilities.

SUBSTANCE: invention relates to public utilities, and in particular to means for removing ice from roofs and drainage pipes of buildings. The device for removing ice from the drainage pipes of buildings contains an electromechanical circuit of a series-connected power supply with a high output voltage, an electric pulse generator, including a pulse capacitor and a thyristor, and a block of inductors - converters of electrical pulses into mechanical ones. The upper part of the spillway pipe and the funnel additionally contain a nozzle made of frost-resistant cast polyethylene with a thickness of at least 4.7 mm, made according to the "pipe-in-pipe" scheme with the formation of a protective pocket between the inner and outer pipes. On the inner and outer pipes there are through holes located opposite one another, and inductors are installed in the protective pocket between the holes. Each of the inductors is made in the form of two coils with cores - indenters, which can move in the radial direction relative to the axis of the nozzle, and the diameters of the indenters are smaller than the diameters of the holes.

EFFECT: invention ensures increased efficiency of city utilities services, which ensure the cleaning of the city from ice and snow, decreased labor costs for organizing the removal of ice deposits with minimal energy consumption and without the involvement of maintenance personnel working in hazardous conditions on roofs, as well as increased safety of pedestrians on city streets.
