Collision and ice preventing device of sea fan

Abstract

The invention relates to a collision and ice preventing device of a sea fan. The device comprises collision preventing cylinder structures with two or more layers, wherein the collision preventing cylinder structure consists of more than two collision preventing rings; the collision preventing rings are vertically laminated; multiple serial connecting rods are vertically inserted in the peripheral direction of the collision preventing cylinder structure; the serial connecting rods penetrate through the collision preventing rings one by one to serially connect the collision preventing rings; the collision preventing rings are spliced by collision preventing rubber pipes passing through the serial connecting rods; the spliced ports of the collision preventing rings are staggered from one another; clamping parts are arranged at the two ends of the serial connecting rods exposed on the collision preventing cylinder structure; the adjacent collision preventing cylinder structures are mutually connected through connecting pieces; and the collision preventing cylinder structures coat a fan foundation, and are lifted with the fan foundation through lifting cables. The collision and ice preventing device has the advantages of easy installation and low manufacturing cost. The structure can effectively buffer the impact of operation and maintenance ships to the fan foundation and the squeezing effect of ice layers in the winter sea icing season on the fan foundation, and can effectively weaken the scouring effect of seawater on the fan foundation.

Description

technical field [0001] The invention relates to an anti-collision and anti-icing device for an offshore fan. Background technique [0002] Offshore wind turbine anti-collision structure is a device installed around the foundation of the wind turbine to prevent or weaken the impact force between the operation and maintenance ship and the barrel arm of the wind turbine foundation when it approaches. [0003] The existing offshore wind turbine anti-collision structures (such as Chinese patent CN103953006A) are mostly steel pipe welded structures, and the anti-collision structure and the fan foundation are welded or bolted, which is a rigid connection, prone to damage, and has high installation costs . At the same time, because there are large gaps between the anti-collision structures, the ice layer can still contact the foundation of the fan through these gaps, so such structures can only play the role of anti-collision, not anti-icing.

[0003] The existing offshore wind turbine anti-collision structures (such as Chinese patent CN103953006A) are mostly steel pipe welded structures, and the anti-collision structure and the fan foundation are welded or bolted, which is a rigid connection, prone to damage, and has high installation costs

At the same time, because there are large gaps between the anti-collision structures, the ice layer can still touch the foundation of the fan through these gaps, so this type of structure can only play the role of anti-collision, not anti-icing.
