The invention relates to a ship resonance icebreaking device which comprises a base, a bearing rod, bearing hydraulic rods, an impact wheel, a cabin door, a cabin door connecting rod and a gear motor, the base is fixed to a ship deck, the bearing rod is hinged to the base, the two sides of the bearing rod are connected with the base through the front bearing hydraulic rod and the rear bearing hydraulic rod respectively, and the front end of the bearing rod is connected with the impact wheel located at the cabin door. The cabin door is connected with a gear motor through cabin door connecting rods. And according to the inherent frequency f1 of the ice layer in the navigation area, the ship running speed is adjusted, so that the impact frequency fn generated by the impact wheel is the same as the inherent frequency f1 of the ice layer, and the resonance icebreaking effect is achieved. Under the condition of ships with the same displacement, larger impact force can be provided for an ice layer. During icebreaking operation, extra power equipment is not needed, the impact wheel is made to rotate by means of the forward advancing speed of the ship, the icebreaking operation is completed, and energy consumption is lower.
本发明涉及一种船舶共振破冰装置,包括基座、承重杆、承重液压杆、冲击轮、舱门、舱门连杆、减速电机,所述基座固定在船体甲板上,基座上铰接承重杆,承重杆两侧分别通过前、后承重液压杆与基座连接,承重杆前端连接位于舱门处的冲击轮,舱门通过舱门连杆连接减速电机。根据所处航区冰层固有频率f1,通过调整船舶行驶速度,使得冲击轮产生的冲击频率fn与冰层固有频率f1相同,达到共振破冰效果。本发明在同排水量船舶的条件下,能给冰层提供更大的冲击力。在破冰作业时,不需要额外的动力设备,依靠船舶向前行进的速度使冲击轮转动,完成破冰作业,能耗更低。
