A model experimental device for an icebreaker tank

Abstract

The invention discloses an experimental device for a pool model of an icebreaker. The experimental device comprises a circulating water tank and a ship model mounting device. The circulating water tank comprises a U-shaped channel, a water pump and a connecting pipe. The U-shaped channel comprises two long straight sections and a turning section. One ends of the two long straight sections are separately connected to the turning section to form a U shape while the other ends of the two long straight sections are connected through the connecting pipe, and the water pump is arranged on the connecting pipe, so that a liquid in the water tan drives floating ices to move; the ship model mounting device comprises a top wall track arranged above the long straight sections of the U-shaped channel,two cross beams mounted on the top wall track and two hydraulic connecting rods separately mounted on the two cross beams. Based on an experimental principle of collision of the moving floating ice tothe navigational speed free ship model, a physical phenomenon of a ship in ice navigation can be simulated relatively truly, and defects that a conventional large ice pool is large in occupied area,long in construction period, high in building cost and the like can be also solved. The invention relates to the technical field of ship model experiments.

Description

technical field [0001] The invention relates to the technical field of ship model experiments, in particular to an icebreaker pool model experiment device. Background technique [0002] In recent years, related industries such as polar ship design and construction, ice-region waterway transportation, and polar resource development and utilization have developed rapidly. At present, countries around the world have set off a new round of research and development of polar ships and marine structures. Polar ships sail in the ice area all the year round. In the design, not only the navigation resistance of the ice floes to the ship should be considered, but also the navigation ability and ice breaking ability of the ship in the frozen sea area should be considered. Due to the great differences in the working conditions and structural forms of polar ships and conventional ships, there are still many technical difficulties in the design and development of polar ships.

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the defects and deficiencies of the existing ice water tank construction technology, and provide a small icebreaker tank model experimental device, which can more realistically simulate the physical phenomenon of ships navigating in ice areas, and avoid large ice water tanks. Defects such as long construction period, high construction cost and complex technology
