Collision protection device based on bidirectional energy absorption
The invention discloses a collision protection device based on bidirectional energy absorption. The collision protection device comprises an energy absorption plate, a first collision protection plate, a second collision protection plate, an upper rotating tooth cylinder, a lower rotating tooth cylinder and an end face gear. The upper and lower rotating tooth cylinders are sleeved on the surface of a protected strut and can rotate freely; the end face gear is mounted on the protected pillar, positioned between the upper and lower rotating tooth cylinders and meshed with the two; at least one group of first collision protection plates and second collision protection plates are respectively mounted on the cylinder walls of the upper and lower rotating tooth cylinders along the circumferential direction; the first collision protection plates and the second collision protection plates are arranged in a staggered mode in the circumferential direction of the cylinder wall. The energy absorption plate is arranged on the outer ring of the upper rotary tooth cylinder and the outer ring of the lower rotary tooth cylinder in a sleeving mode and provided with installation grooves for the collision protection plates to stretch out. The mode that the energy absorption plates are combined with the reverse rotating mechanism is adopted, circumferential and radial energy absorption of the energy absorption materials and ship body speed steering are achieved, the energy absorption efficiency can be greatly improved, the contact area is rapidly increased, and the collision force peak value is effectively reduced.
本发明公开了一种基于双向吸能的碰撞防护装置，包括吸能板、第一碰撞防护板、第二碰撞防护板、上部旋转齿筒、下部旋转齿筒、端面齿轮；上下部旋转齿筒套装于被防护支柱表面并能自由转动；端面齿轮安装于被防护支柱上，位于上下部旋转齿筒中间与二者啮合；上、下部旋转齿筒的筒壁沿周向分别安装至少一组第一碰撞防护板和第二碰撞防护板；第一碰撞防护板与第二碰撞防护板沿筒壁周向交错排布；吸能板套装于上部旋转齿筒与下部旋转齿筒的外圈，其上设有用于各碰撞防护板伸出的安装槽。本发明采用吸能板与反向旋转机构相结合的方式，实现吸能材料的周向与径向吸能以及使船体速度转向，可大幅提高吸能效率、快速增大接触面积和有效减小碰撞力峰值。
