Description
Technical Field
The utility model relates to the technical field of offshore wind power generation equipment, in particular to a floating wind power generation platform.
Background
At present, offshore wind power development is mainly concentrated in shallow water areas, so that a wind power generation platform mainly adopts fixed foundations such as single piles or jackets and the like. Along with the gradual reduction of offshore resources, the development of offshore wind power resources gradually goes to deep water, and along with the increase of water depth, the construction and installation costs of the traditional fixed foundation are greatly increased, so that a floating foundation suitable for larger water depth becomes a main foundation form for future offshore wind power development.
In order to adapt to severe sea conditions and surges of deep water, the structure and the weight of the floating platform need to be increased to ensure that the platform equipment can safely run, but excessive platform weight needs to be increased, extra design and construction cost is required to be increased, the reinforcement of the platform structure also needs to be additionally considered, but the simple increase of the structural size and the mass cannot completely solve the operation safety of the ocean floating platform, and the current requirement of offshore wind power development cannot be well met.
Disclosure of Invention
The utility model provides a floating wind power generation platform with simple structure and strong wind wave resistance.
The floating wind power generation platform comprises a floating foundation frame, wherein the middle part of the floating foundation frame is downwards extended with a stand column, and more than two damping plates for increasing underwater resistance are arranged at the lower part of the stand column.
The floating wind power generation platform is characterized in that the damping plate is positioned at the lower part of the stand column under water, when the floating foundation frame swings, the stand column can drive the damping plate to generate relative swinging motion under water, the damping plate can receive reverse thrust opposite to the motion direction, the larger the swing amplitude is, the faster the relative peak motion speed at the lower part of the stand column is, the larger the reverse thrust is, the passive damping braking force can be effectively provided for the floating foundation frame, the damping braking force and the thrust formed by sea wind force and waves received by the floating foundation frame are mutually offset, the wind resistance and the wave resistance of the floating wind power generation platform can be improved, and the stability of the floating wind power generation platform is improved.

Detailed Description
As shown in fig. 1, a floating wind power generation platform comprises a floating foundation frame 1, wherein the floating foundation frame is used for installing a wind generating set 5, a stand column 2 downwards extends from the middle of the floating foundation frame, and more than two damping plates 3 for increasing underwater resistance are arranged at the lower part of the stand column. The damping plate is positioned at the lower part of the stand column under water, when the floating foundation frame swings, the stand column can drive the damping plate to generate relative swinging motion under water, the damping plate can bear reverse thrust opposite to the motion direction, the larger the swing amplitude is, the faster the relative peak motion speed at the lower part of the stand column is, the larger the reverse thrust is, the passive damping braking force can be effectively provided for the floating foundation frame, the damping braking force and the thrust formed by sea wind force and waves borne by the floating foundation frame are mutually offset, the wind resistance and the wave resistance of the floating wind power generation platform can be improved, the stability of the floating wind power generation platform is improved, and further, according to the lever principle, the longer the length of the stand column is, the more stable the floating foundation frame is positioned at the upper part of the stand column under the condition that the damping plate provides the same damping braking force.
Because the wind direction at sea is sometimes unstable, the damping plates are arranged at the lower part of the upright post in a perpendicular manner in pairs in order to adapt to sea wind blown from all directions and improve wind resistance and wave resistance. When the floating wind power generation platform swings, the damping plates which are arranged vertically can generate relative swinging motion under water, can be decomposed into vertical motion in two directions which are vertical to each other, and provide damping braking force in two vertical directions.
The floating foundation frame comprises four floating cylinders 11 and six truss units 12, wherein three floating cylinders are distributed in a triangular shape, the other floating cylinder is arranged in the middle of the three floating cylinders, and the floating cylinders are connected in pairs through the truss units. The wind power generation foundation can be arranged on the floating cylinders, and the floating cylinders are connected with each other through the truss units, so that the structure is simple, the cost is reduced, the stability of the floating cylinders can be ensured, and the wind resistance and the wave resistance are improved.
The ballast tank is further arranged in the upright post, and the gravity center of the whole floating wind power generation platform can be moved downwards by injecting seawater into the ballast tank, so that the stability of the floating wind power generation platform is improved, the reverse restraining torque of rolling and pitching of the floating wind power generation platform is improved, and larger damping braking force is provided.
In order to improve the structural stability of the whole floating wind power generation platform and realize light weight and cost reduction, a steel cable 4 or a supporting steel rod is further arranged between the bottom of the upright post and the floating foundation frame, so that the weight of the floating wind power generation platform is greatly reduced, the structural strength of the floating wind power generation platform is enhanced, and the operation safety of the floating wind power generation platform is improved.
