The invention provides an attached barb type reinforced suction anchor, and belongs to the technical field of suction anchors. The reinforced suction anchor comprises an anchor body, a barb mechanism and a hinge. The barb mechanism is arranged on the periphery of the anchor body through the hinge, so that when the barb mechanism is subjected to upward acting force, the free end of the barb mechanism is folded towards the anchor body with the hinge as the rotation center. When the barb mechanism is subjected to downward acting force, the free end of the barb mechanism rotates away from the anchor body with the hinge as the rotating center, and the bearing radius of the anchor body is enlarged. When the attaching barb type reinforced suction anchor is subjected to acting force from bottom to top, the barb mechanism is in a closed state, and the downward movement of the attaching barb type reinforced suction anchor is slightly hindered; when the adhesion barb type reinforced suction anchor is located in a soil layer and is subjected to upward drawing acting force, the barb structure is expanded under the acting force from top to bottom, the bearing radius is enlarged, and therefore the bearing capacity of the suction anchor can be remarkably improved in the vertical direction and the horizontal direction.

    本发明提供一种附着倒刺式加强吸力锚,属于吸力锚技术领域。该加强吸力锚包括锚体、倒刺机构和铰链。倒刺机构通过铰链设置于锚体的外周,使得,当倒刺机构受到向上的作用力时,倒刺机构的自由端以铰链为旋转中心向锚体合拢;当倒刺机构受到向下的作用力时,倒刺机构的自由端以铰链为旋转中心作远离锚体的旋转运动,使锚体的承载半径得以扩大。该附着倒刺式加强吸力锚受到自下向上的作用力时,倒刺机构处于关闭状态,对该附着倒刺式加强吸力锚的向下运动阻碍小;在该附着倒刺式加强吸力锚处于土层内受到向上的拉拔作用力时,该倒刺结构受到自上向下的作用力而展开,承载半径得以扩大,因此,其能够在竖直方向和水平方向显著提高吸力锚的承载能力。
