WATER ICE BREAKER WITH AUTOMATIC NOZZLES FOR PREPARATION OF SLOTS IN ICE FORMATIONS Russian patent published in 2020 - IPC F25C5/10 

FIELD: ice-technology.

SUBSTANCE: heated water is used as heat carrier. Device consists of hollow housing of rectangular cross-section, on ends of which there are bushings with internal thread, which are connected with cavity of housing, on lower edge of which there is a row of threaded holes for installation of nozzles, axes of which are parallel to axes of side bushes, and nozzles themselves open outlet of water jets only in contact with ice. On the lower part of the side walls of the housing between the holes there is a row of vertical grooves with depth decreasing upwards and width to receive ice projecting on walls and its melting, which provides formation of even walls of the slot. In upper part of side bushes there are guides and supply tubes, at that upper ends of pipes are rigidly interconnected by transverse pipe, through which hot water is supplied into guide pipes and further into ice breaker housing. In lower part of side bushings at first cut, two nozzles are installed, at second and next cutter one atomizer and guide rod are installed to prevent deviation of device from preset direction.

EFFECT: invention is intended for cutting of ice during works on making of lanes in ice, for investigation of glaciers and accumulations of sea ice – ice hummocks and grounded hummocks, for extraction of ice-frozen materials and equipment and other similar works related to destruction of ice.
