The empennage type towing anchor comprises an anchor handle, an anchor fluke and an empennage, the anchor handle is used for being connected with an anchor chain, and the top of the anchor fluke is connected with the anchor handle. And the empennage is arranged at the tail part of the anchor fluke, extends outwards and is inclined downwards. In the process that the anchor flukes penetrate into the soil body, the empennages make contact with the soil body so as to bear resistance bending moment from the soil body, the empennages push the tails of the anchor flukes upwards, and the heads of the anchor flukes are driven to turn downwards to penetrate into the soil body. Compared with the prior art, in the process that the towing anchor penetrates into a soil body, soil pressure acting on the empennage can provide torque to delay the rotation process of the anchor fluke, resistance bending moment from the soil body promotes the empennage to push the tail of the anchor fluke upwards, and the head of the anchor fluke is driven to turn downwards to penetrate into the soil body. Therefore, the anchor fluke can obtain larger penetration depth and bearing capacity.

    本发明涉及一种尾翼型拖曳锚,包括锚柄、锚爪以及尾翼,锚柄用于连接锚链,锚爪的顶部连接锚柄。尾翼设置在锚爪的尾部,尾翼向外延伸且向下倾斜设置。锚爪在贯入土体的过程中,尾翼与土体接触从而受到来自土体的阻力弯矩,尾翼向上推动锚爪的尾部,驱使锚爪的头部下翻贯入土体。本拖曳锚与现有技术相对比,拖曳锚在贯入土体的过程中,作用在尾翼上的土压力可以提供一个力矩延缓锚爪旋转的过程,来自土体的阻力弯矩促使尾翼向上推动锚爪的尾部,驱使锚爪的头部下翻贯入土体,令锚爪从而获得更大的贯入深度和承载力。
