Description

Technical Field

[0001] The utility model relates to the technical field of stable supports, in particular to a stable support for offshore wind power generation. Background Art

[0002] As the world's offshore wind power begins to enter a large-scale development phase, China's offshore wind farm construction has also begun. In terms of offshore wind power, China's eastern coastal areas have about 750 million kilowatts of exploitable wind energy resources. Not only is the resource potential huge, but the market conditions for development and utilization are also good. Since China's coast is often affected by typhoons, the construction conditions are relatively complex. However, the sea level is generally flat, the wind has basically no resistance, the average wind speed is high, and the wind shear is also smaller than on land. In addition, the frequency of wind direction changes at sea is also lower than on land. Therefore, the wind energy at sea is very stable. Since there are no obstructions at sea to reduce the wind speed, the wind force at sea is generally greater than the wind force on land, so the offshore wind force is relatively stable. The stability requirements of the power generation device are high; the existing offshore wind power generation device casts the wind power piles inside the concrete platform to fix the wind power generation device, but due to the high height of the wind power generation device, the area affected by the offshore crosswind is large, and the fixed point position of the wind power pile is relatively low, the wind power pile is prone to breakage, thereby affecting the wind power generation process. Some construction teams install fixed brackets around the wind power piles, but the position of the fixed brackets cannot be adjusted, and cannot meet the stability requirements under different wind directions and different wind strengths. It is not practical. For this reason, we propose a stable bracket for offshore wind power generation to solve the above problems. Utility Model Content
