(57) Abstract:

The invention is intended for disassembly of the ice, melting of beams desired shape and size of the array of the iceberg or glacier. The ice-cutter includes a hollow body. It consists of two concentrically spaced semi-bodies in the form of a truncated part of the circumference of the pipes connected interfacing plate. Internal semi-body and the plate is insulated. On the working surface of the external Polycarpus made grooves to accelerate drainage of water from the melting ice. Along the perimeter of the outlet grooves transit is the recipient. The ice-cutter equipped with intake and discharging pipelines for water, pump, piping for the inlet and outlet of the coolant. The invention provides an efficient derivation ' ice-blocks. 3 Il.

The device relates to the field of processing ice heating bodies which are in contact with him. A device for sinking shafts in the thickness of the ice by melting using downward flame resulting from the combustion of liquid fuel injectors or gases in the gas burners. The resulting water is collected by the pump and discharged outside the zone melting (SU 153727, 1963, E 21 D 3/00).

The famous ice-cutter heat, containing a hollow body, the piping for the inlet and outlet of the heat carrier (SU 1781518 A1, 15.12.92, F 25 C 5/10). The body is made in the form of a tubular frame of a prism with a rectangular base. The heat transfer medium (water, steam or heated gas flowing from the nozzle holes in the base frame. This ice-cutter is the closest to this invention by the technical nature. The disadvantages of it is low efficiency in the use due to the loss of half of thermal energy emitted in the direction opposite to the working area side; wasteful heating of the water formed in the working area; systematic breaking contact between the working part with ice because of the constantly formed layer of water at the surface of contact. It should be noted that one of the most important factors affecting the performance, when all other conditions being equal, is formed between the working body and the layer of water ice, which, breaking the contact between them and using thermal energy is used to melt accumulated ice on your heating, dramatically reduces the efficiency of the melting ice.

Technology and effective cut (derivation) ' ice-blocks of the desired shape and size of the array of the iceberg or glacier.

To achieve this, the technical result of the ice-cutter heat, containing a hollow body, the piping for the inlet and outlet of the coolant, characterized in that the housing consists of two concentrically spaced semi-bodies, of which the external surface is made of the grooves, and the inner thermally insulated, and the ice-cutter provided with a water intake, the intake and discharging pipelines, pump.

The invention is illustrated by drawings, where:

in Fig.1 shows a diagram of the operation of the ice-cutter thermal (vertical penetration);

in Fig.2 projections of ice-cutter heat;

in Fig.3 - section a-a in Fig.2.

The ice-cutter includes a hollow body 1, consisting of two concentrically spaced semi-bodies 2, 3 in the form of two truncated at 2/5 of their circumferences of the pipes. Internal semi-body 2 with walls of great thickness insulated (made of insulating material or covered with them). On the working surface of the outer Polycarpus 3 - working body is made in a spiral V-shaped groove 4 (sinusoidal) to accelerate removal of the formed water, starting at the bottom of the line of contact of the working body of ice covering 3/5 of a circle and extending all over DL is which, as the inner semi-body 2 made of insulating material or covered to reduce heat loss.

The ice-cutter also includes a tube 6 by line 7 for supplying a fluid pipe 8 pipe 9 to drain the coolant, transit recipient 10, intaking and discharging pipes 11, 12, pump 13, source 14 heating of the heat carrier, collapsible rod 15 fastened together with the upper part of the housing 1 to provide a uniform and vertical immersing it in ice. The ice machine 10 is located on the perimeter of the outlet grooves 4 and is formed with l-shaped plates attached to the housing 1. He tightly covers the grooves 4 from the output line from the work area until the line is complete and has conclusions that connects to the intake pipe 11.

Across the space of the body cavity in the working area are the ribs, which simultaneously promote mixing of the coolant.

The ice-cutter works as follows. On an iceberg or glacier chosen place for the development and label the future ' ice-blocks. Then installed various accessories, are placed in the markup of the ice-cutters and rods 15 (t is - the working agent leads to heating of the working body and the immersion in ice-cutter ice array to a depth determined by the length of the rods 15. The resulting water - working body is given by the pump. The pipes 11 and 12 through the pump 13 taking and discharge of water resulting from melting ice.

Improving the efficiency of fusion of ice is achieved by reducing internal and external unproductive losses of thermal energy, increasing the area of the working body and the specific pressure on the ice surface, the acceleration of output produced water from the work area. Technically the problem is solved by using as a heat insulator inner tube, drawing on the work surface of the outer tube in a spiral V-shaped grooves, the use of transit of the receiving water for the extraction of water from the work area.

The inner tube has a large wall thickness, teploizolirovat plate and reducing unproductive losses of heat inside the working area. The inner surface of the plate which is not covered, is covered with insulating material.

Each specific model of ice-cutter with its specified capacity, speed of construction, size the of them falling into the ice and accelerate the removal of the formed water, and their number and angle of inclination of the front movement will make these processes are simultaneous and uniform across the working area, will reduce energy losses on non-productive heat generated in the working area of the water will increase the radiant heat surface of the working body, will increase the unit pressure of the working body on the ice and improve his contact with him, which ultimately will increase the efficiency of melting ice.

Sealing grooves 4 along the perimeter zone of water intake from the external environment allows the use of a pump 13 for pumping produced fluids and optimize this process, since the capacity of the pump 13 can be adjusted.

Pruning beam of ice from the bottom is slightly altered equipment using trucks, rods and rods for pulling the ice-cutter under the ice beam.

Thus, transit Glandless the recipient, allowing you to accelerate the drainage of water from the work area, internal insulation, allowing to reduce wasteful loss of heat, V-grooves, accelerating the drainage of water from the work area, reducing the loss of heat energy needed to heat it, increasing the specific pressure of the working body on ice the solution performance.

The ice-cutter heat, containing a hollow body, the piping for the inlet and outlet of the coolant, characterized in that the housing consists of two concentrically spaced semi-bodies, of which the external surface is made of the grooves, and the inner thermally insulated, and the ice-cutter provided with a water intake, the intake and discharging pipelines, pump.

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.
