Description
Technical Field
The utility model relates to the technical field of offshore wind power facility structures, in particular to an anti-scouring device for an offshore wind power suction pile.
Background
With the proposal of the national '30.60 target', the green development and the high-efficiency development become the future direction of the energy system construction in China, wherein offshore wind power has become a powerful guarantee for realizing the target. Offshore wind power has many advantages, such as: the offshore wind has the advantages of abundant resources, stable wind speed, zero pollution, zero emission, no noise, no visual pollution, no land occupation, large installed capacity and the like.
With the continuous development of offshore wind farms in recent years, the development from offshore to deep open sea has progressed, and therefore, a fan foundation suction foundation adapted to the deep open sea has become one of the choices. However, the washing of the seabed is not negligible as the pile diameter is increased and the hydrological environment is deteriorated. At present, in ocean engineering, the most common seabed scour prevention measures are as follows: underwater stone throwing, sand bag piling, concrete mattress sinking, protective support pile driving and the like. The basic principle is that the covering layer is used for weakening the scouring effect of vortexes generated by water flow around the pile body on the sea bed surface around the pile body, the leading idea of the scouring prevention methods is 'blocking', and the underwater scouring is hopefully prevented by objects which are not afraid of scouring. Although the method has a certain anti-scouring effect, the problem of 'secondary scouring' of the seabed can also occur due to the existence of solid objects such as underwater riprap, sand bags, concrete mattress pads and the like.
SUMMERY OF THE UTILITY MODEL
In view of the above, the utility model aims to provide an offshore wind power suction pile anti-scouring device which is simple in structure, low in manufacturing cost and good in anti-scouring effect.
