Anti-collision device for riser of ocean platform
The invention discloses an ocean platform riser anti-collision device which comprises an air bag, a fender, a stress conversion mechanism and a protective shell, the air bag wraps the periphery of an ocean platform riser, the protective shell is arranged on the outer side of the air bag in a sleeving mode and connected with the air bag, and the fender is located on the outer side of the protective shell and connected with the protective shell through the stress conversion mechanism. The stress conversion mechanism is arranged to be capable of changing the direction of the impact load, perpendicular to the axis direction of the vertical pipe, borne by the fender so as to form a tensile load in the opposite direction to be applied to the protection shell, the stress conversion mechanism can convert the impact load of a ship or sea ice into the tensile load, the protection shell deforms towards the outer shape, and the stress conversion mechanism can convert the impact load of the ship or sea ice into the tensile load. The integrity of the ocean platform riser is protected; the air bag not only provides buoyancy for the whole anti-collision device for the ocean platform riser, but also has a buffering effect on an impact load when the impact load acts on the air bag, so that the impact load is prevented from directly damaging the ocean platform riser, and the protection purpose is also achieved.
本发明公开了一种海洋平台立管防撞装置，包括气囊、护舷、受力转换机构和保护壳，气囊包裹在海洋平台立管的外周，保护壳套在气囊的外侧并与气囊连接，护舷位于保护壳的外侧并通过受力转换机构与保护壳连接，受力转换机构设置为能够将护舷受到的垂直于立管轴线方向的冲击载荷的方向改变以形成相反方向的拉伸载荷施加在保护壳上，本发明设计的受力转换机构，能够将船舶或海冰的冲击载荷转换为拉伸载荷，保护壳将发生朝外形变，保护海洋平台立管完整性；气囊不仅为海洋平台立管防撞装置整体提供浮力，而且在冲击载荷作用在气囊上时气囊对冲击载荷具有缓冲作用，防止冲击载荷对海洋平台立管的直接破坏，同样起到保护目的。
