The invention provides a torpedo anchor which is provided with an additional anchor body capable of being unfolded and turned outwards. The torpedo anchor is mainly composed of an anchor body, an anchor wing, additional anchor bodies, a fixing hinge, an anchor head and the like. The four additional anchor bodies are cylindrical as a whole when not unfolded. The ends, away from an anchor head, of the additional anchor bodies are horn-mouth-shaped, and the other ends of the additional anchor bodies are fixedly connected to the anchor body through fixed hinges. The surface of the anchor body is smooth and the whole shape is similar to that of a common torpedo anchor. When the novel torpedo anchor is used, the novel torpedo anchor is the same as a common torpedo anchor when penetrating to theseabed, and the additional anchor bodies are tightly attached to the anchor body. However, when the torpedo anchor is pulled, the additional anchor body is unfolded and turned outwards under the action of torque generated by the force acting on the additional anchor body to the fixed hinged of the anchor head part such that the stressed area is enlarged, and the ultimate uplift bearing capacity ofthe torpedo anchor is greatly improved.
本发明提出了一种设有附加锚身且附加锚身可展开外翻的鱼雷锚。该鱼雷锚主要由锚身主体、锚翼、附加锚身、固定铰和锚头等组成。附加锚身共四块,未展开时整体呈圆筒状。其中,附加锚身远离锚头端呈喇叭口状,另一端与锚身通过固定铰连接在一起。锚身表面平整,整体与普通鱼雷锚外形接近。本文中提出的新型鱼雷锚在使用时,贯入海底时与普通鱼雷锚相同,附加锚身紧紧贴合在锚身主体上。但在鱼雷锚受到拉力时,因为作用在附加锚身上的力对锚头部的固定铰产生力矩,附加锚身在此力矩的作用下展开外翻,扩大了受力面积,使鱼雷锚的极限抗拔承载力大大提高。
