ICICLE REMOVAL DEVICE Russian patent published in 2024 - IPC E04D13/00 

FIELD: construction.

SUBSTANCE: invention relates to construction, in particular to devices for removal of ice in the form of icicles and ice from roof eaves, projecting elements of building facades, drains. Icicle removal device comprises: a fuselage having a nose part, a tail part and a middle part located between them, a manipulator with a process tool coupled with the fuselage nose part, drive internal combustion engine connected to electric current generator located in fuselage tail, electric motors with drive shafts, located in the middle part of fuselage, drive shafts kinematically connected to axes of fans through reduction gears, fans installed in the middle part of the fuselage so that they have the possibility to create a fluid flow from the hole in the upper part of the fuselage in the direction from the fuselage to the sides, wings closed at the ends with fairings, made so that the lifting force is created by the fluid flow in the direction from the fuselage to the sides, a communication system and on-board control equipment located in the nose of the fuselage, a compressor with a receiver located in the nose of the fuselage, made with possibility of supplying compressed air to the nozzle device of the drive of the technological tool of the manipulator, process tool drive comprising a lever mounted on an axis connected to a manipulator link, at that, on one arm of the lever a process tool is installed, on the other arm a nozzle assembly is installed, made in such a way that the supply of the process tool to the icicles is performed by turning the lever relative to the axis with the outflow of a jet of compressed air from the nozzle apparatus, propeller-driven vehicles mounted on rods, made with possibility of pitch, yaw and roll control in all flight modes, flaps installed in housings located under rear edge of wings and connected to flap drive devices, flap drive devices configured to turn the flaps relative to the axis so that in one of the positions the flaps are inclined forward, and in the other position they are inclined backwards, an accumulator, a fuel tank located in the middle part of the fuselage, and a landing gear.

EFFECT: higher operational reliability of the roof.
