An experimental device for continuous collision between crushed ice and marine structures

Abstract

The invention discloses a novel device for continuously colliding pools of crushed ice and marine structures, comprising: an experimental pool, a crushed ice launching mechanism, a structure fixing mechanism, a crushed ice collecting mechanism, a crushed ice conveying mechanism and a water circulation mechanism. The crushed ice launching mechanism is installed at the left end of the experimental pool to launch the crushed ice and control the initial velocity of the crushed ice. The structure fixing mechanism is installed in the middle of the experimental pool to constrain the movement of marine structures. The crushed ice collection mechanism is installed at the right end of the experimental pool, and the crushed ice is recovered to the crushed ice conveying mechanism through the rotating motion of the roller. The crushed ice conveying mechanism is installed on one side of the experimental pool, connecting the left end and the right end of the experimental pool. It is used to return the crushed ice cubes collected by the crushed ice collection mechanism to the crushed ice launching mechanism, and the cycle is repeated. The water circulation mechanism is connected to the left and right ends of the experimental pool, and the water circulation is realized through the operation of the pump.

Description

technical field [0001] The invention relates to a water tank experiment device and method for ice floes and marine structures to collide, and belongs to the technical field of shipbuilding. Background technique [0002] In recent years, with global warming, the area and thickness of sea ice in the Arctic have been decreasing, making the development and utilization of polar resources gradually possible. At present, the development of polar resources by human beings is deepening, and the polar regions have become an important strategic location. According to public information, the Arctic has extremely rich natural resources (13% of unproven oil reserves, 30% of undeveloped natural gas reserves and 9% of the world's coal resources). Compared with the rich mineral resources, the opening of the Arctic waterway is more attractive. For our country, opening up the Arctic shipping route has obvious distance advantages. Compared with traditional routes, the distance can be shortene...

Problems solved by technology

Due to the complexity of the collision process between marine structures and crushed ice, especially the continuous collision process, it is difficult for current theoretical formulas and numerical simulation methods to give reasonable analysis results, and the cost of actual ship experiments is very expensive, and the environmental variables are difficult to predict. control
