WATER ICE CUTTER FOR MAKING SLOTS IN ICE FORMATIONS Russian patent published in 2017 - IPC F25C5/10 

FIELD: construction.

SUBSTANCE: invention is intended for cutting ice during works on making mines in ice, studying glaciers and sea ice conglomerations, extracting materials and equipment frozen into ice, and other similar works connected with ice destruction. The device for cutting ice with hot water comprises a hollow housing with bushings with internal threads, communicating with the housing cavity, mounted at the housing ends. At the lower housing edge, a row of openings is provided for installing nozzles, whose axes are parallel to the axes of the side bushings. At the bottom of the side bushings, two nozzles are installed in the beginning of the operation; and during the subsequent operation, one nozzle and one guide rod are installed. Wherein the housing is made rectangular in the cross-section. On the lower part of the housing side walls, between the openings, a row of vertical grooves with a decreasing depth and width is made, which ensures the formation of even slot walls. In the upper part of the side bushings, pipes are installed, which are simultaneously used as guide and supplying ones. Wherein the upper ends of the pipes are rigidly connected to one another by a transverse pipe, through which hot water is supplied to the guide pipes and further into the device housing.

EFFECT: increasing the device reliability.
