Ice breaking and removing method utilizing high-speed water jet slamming characteristics
The invention belongs to the technical field of polar region ship ice breaking navigation, and particularly relates to an ice breaking and removing method utilizing high-speed water jet slamming characteristics. According to the ice breaking and removing method, ice breaking is conducted through the slamming effect of high-speed water jet, the high-speed water jet can directly impact the ice surface to cause bending damage to the ice surface, a layer ice structure can be broken more effectively through generated slamming damage and stretching waves due to the fact that the high-speed water jethas large water hammer pressure, broken ice can be cleaned and secondarily damaged through lagging flow formed by the high-speed water jet, and therefore, effect of cleaning a channel is realized, the risk that the ship side is limited and stuck is further reduced, and meanwhile, the ice breaking resistance of a polar region ship is reduced. According to the ice breaking and removing method, by means of the multi-nozzle mode, the range of the ice breaking width can be adjusted by referring to the ship width, the water jet pressure can be adjusted according to the ice thickness, water used forwater jet can be conveniently supplemented, and the influence on the marine ecological environment is small; ice breaking is conducted through the high-speed water jet technology, and the advantagesof being low in cost, easy to implement, high in efficiency and the like are achieved.
本发明属于极地船舶破冰航行技术领域，具体涉及一种利用高速水射流砰击特性的破冰清冰方法。本发明利用高速水射流砰击作用进行破冰，高速水射流可以直接冲击冰面对冰面造成弯曲破坏，利用其具有较大的水锤压力，产生的砰击毁伤和拉伸波能更有效破环层冰结构，高速水射流形成的滞后流还可以对碎冰进行清理和二次破损，达到清理航道的作用，进一步减小船侧受限被卡住的风险，同时减小极地船舶的碎冰阻力。本发明通过多喷口方式，可以参考船宽进行其破冰宽度的范围，可以根据冰厚调节水射流压力，水射流所用水可以便捷补充，并且对于海洋生态环境影响很小。本发明利用高速水射流技术进行破冰，具有成本低、易实现、效率高等优点。
