Abstract
PURPOSE: To crush effectively and economically the ice plate which approaches or form in the surroundings of a structure by composing an ice crusher of a pressure- receiving mechanism for receiving the pushing force of an ice plate, and underwater ice crusher member, a pressure mechanism for bringing the member into collision with the ice plate, and an energy-transmitting mechanism.
CONSTITUTION: An ice crusher comprises : a pressure-receiving mechanism 1 for receiving the pushing force of an ice plate 8; an ice crusher member 4 situated under the surface of the sea for crushing the ice plate 8 form the lower surface; a pressure mechanism 3 which store the energy of the pushing force of the ice plate 8 and releases the energy at an appropriate time so as to bring the member 4 into collision with the lower surface of the ice plate 8; and a transmission mechanism 3 for transmitting the energy of the pushing force of the ice plate 8 received by the mechanism 1 to the mechanism 3. By this constitution, which needs no artificial energy, ice plates and ice blocks around a structure can be crushed extremely economically and effectively, and it is possilbe to eliminate danger of breakage of the structure due to the ice pressure.
