The invention discloses a shield type icebreaker. Ice breaker body, an icebreaking device is arranged on the icebreaker body; the ice breaking device comprises a shield tunneling machine, a supportingstructure and a vibration reduction structure. The shield tunneling machine is fixed at the front end of the icebreaker body; support structure realized by adopting steel cable, one end of the steelcable is hinged to the shield tunneling machine; the other end of the steel cable is hinged to the icebreaker body; the shock absorption mechanism comprises a high-damping rubber damper and an annularhigh-damping rubber damper; when the icebreaker body is pushed forwards, the shield tunneling machine crushes an ice layer in front of the icebreaker body and then discharges the crushed ice layer, at the moment, the supporting mechanism reduces local stress generated to the icebreaker body when the shield tunneling machine works, and the damping mechanism consumes vibration energy generated to the icebreaker body when the shield tunneling machine works; the icebreaking ship has the advantages of being low in cost, high in icebreaking efficiency, low in energy consumption and capable of beingused for icebreaking in a deep sea area and a shallow sea area, and a ship body is not prone to being stuck by an ice layer.
本发明公开了一种盾构式破冰船,包括破冰船船体,破冰船船体上设置有破冰装置,破冰装置包括盾构机、支撑结构和减振结构,盾构机固定在破冰船船体的前端上,支撑结构采用钢索实现,钢索的一端铰接在盾构机上,钢索的另一端铰接在破冰船本体上,减震机构包括高阻尼橡胶阻尼器和环形高阻尼橡胶阻尼器,当破冰船船体向前推进时,盾构机将破冰船船体前方的冰层粉碎后排出,此时支撑机构减小盾构机工作时对破冰船船体产生的局部应力,减震机构消耗盾构机工作时对破冰船船体产生的振动能量;优点是成本较低,破冰效率较高,能耗较低,船身不容易被冰层卡住,既能用于深海区域也能用于浅海区域破冰。
