Background
An offshore wind turbine installation platform is a core device for building an offshore wind farm. The pile foundation mainly comprises a platform main body, pile legs, a lifting device, a crane and the like. During operation, the platform inserts the spud leg into the seabed through elevating gear, then lifts the main part from the surface of water to the operating position, provides a stable platform for the fan installation.
The pile leg in the existing offshore wind turbine installation platform is generally additionally provided with a pile shoe at the lower end of the pile leg, the pile leg is supported on the sea bottom surface through the pile shoe, in a common saying, the foundation is not firm, the pile leg shakes around mountains, and the existing pile shoe is not reinforced when supporting the sea bottom surface, so that the pile leg is not stable. How to avoid hydraulic or electric driving devices as much as possible during underwater operation needs consideration and attention in the design scheme of the reinforced pile shoe.
In addition, the self-propelled ship with the positioning pile legs only has the transportation capacity of the wind turbine generator set. Before the installation operation, the positioning pile is inserted into a seabed, so that the ship body can be relatively fixed, the stability of the ship body is improved, the ship body floats in water by means of buoyancy of the ship body, but when the wind waves are large, the ship body can still fluctuate along with the waves, and the installation operation is still influenced. In order to solve the influence of wind and wave, a self-elevating (non-self-propulsion) platform installation mode is adopted. The self-elevating (non-self-propelling) platform is an installation platform with pile legs capable of self-elevating, can not self-propel and can not transport a wind turbine generator, the wind turbine generator needs to be towed to a designated working place by a tugboat, the pile legs are inserted into a seabed supporting platform after arriving at a site, the platform is lifted out of the water through a hydraulic elevating device, and a stable platform which is not influenced by waves is formed. Then the crane on the platform finishes hoisting the fan. Because self-propulsion cannot be realized, the installation efficiency is low, and an auxiliary ship is needed. At present, a crane is adopted to install a fan, and the working efficiency of installation is low because the sea often has large wind and is influenced by sea wind.
