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.1 cl

Description

The invention relates to ice-making devices and is intended for cutting ice with hot water during the manufacture of holes in ice, researching glaciers and piles of sea ice - hummocks and hammers, extracting materials and equipment frozen into ice, and other similar works related to ice breaking. Heated water is used as a heat carrier.

Known devices for steam and water cutting of ice [1-9]. All of them, to one degree or another, are effectively used to prepare slots in homogeneous ice. However, in the case of making slots in ice formations such as hummocks and hammers, which are piles of broken ice with internal voids between blocks of ice, their efficiency is reduced due to the irrational use of thermal energy. Overheating of devices and their failure can also occur.

The closest adopted prototype is a water ice cutter Moreva et al. [5], in which hot water is supplied through a hose to the ice cutter inlet pipes, and through them into the ice cutter body, from where it is fed through nozzles to the bottom, where a number of holes are threaded. These holes, when combined, form a gap in the ice into which the ice cutter plunges. In this case, the guides located at the edges of the ice cutter provide for fixing its position, as well as a continuous slot in the ice without underwater jumpers. When cutting hummocks and hammers, consisting of blocks frozen between themselves and voids between them, situations are not uncommon when a certain segment of an ice-cutter enters a cavity. The disadvantage of the prototype is that in this case, hot water from this segment is poured out freely, diverging without benefit, thereby reducing the water pressure in the ice cutter and thereby reducing the cutting speed.

The purpose of the invention is to increase the cutting efficiency when using a device for cutting ice piles, such as hummocks and hammers.

The technical result is achieved by replacing constantly open nozzles with automatic ones, which open the release of water jets only in contact with ice.

The operation of the device is as follows. Hot water is supplied to the ice cutter under pressure. At the time the ice cutter is installed on the ice, the nozzles open and ice melts at the point of contact. Due to the increased diameter of the nozzles along the edges of the ice cutter, small wells are formed at the edges of the slot. If a cavity is encountered during cutting on the ice cutter’s path, the nozzles on that part of the ice cutter that fell on the cavity are closed, and the water flow redistributes from uniform to those parts of the ice cutter that are in contact with ice. Thus, the cutting speed in a particular section of ice with a cavity is increased and, accordingly, the cutting efficiency as a whole.

After the first slot, one of the side nozzles is replaced with a guide. During subsequent cutting, this guide is inserted into the well at the edge of the slot formed by the edge nozzle. This ensures the manufacture of a continuous slot in ice without underwater bridges.
