Foundation structure of single-column type offshore wind turbine

Abstract

The invention discloses a foundation structure of a single-column type offshore wind turbine. The foundation structure of the single-column type offshore wind turbine comprises a bearing platform. Thetop of the bearing platform is fixedly connected with four connecting frame rods, the four connecting frame rods are symmetrically arranged at the top of the bearing platform in pairs, the top ends of the four connecting frame rods are fixedly connected through an upper frame plate, the adjacent two connecting frame rods are fixedly connected through three cross connecting ribs, and the left andright sides of the top of the upper frame plate are fixedly connected with side supporting rods. The middle point of the top of the upper frame plate is fixedly connected with a generator tower. Supporting plates are fixedly connected to the ends, close to the generator tower, of the side supporting rods. The generator tower is in mutual contact with the sides, close to the generator tower, of thesupporting plates. The foundation structure of the single-column type offshore wind turbine is simple in structure, good in foundation stability, high in foundation bearing capacity, not prone to generating problems such as unstable fixation or easy collapse, low in construction cost and beneficial to improving construction efficiency, and convenient construction operation is achieved.

[0002] A wind turbine is a device that converts wind energy into electrical energy. It is mainly composed of blades, generators, mechanical components and electrical components. According to the different rotation axes, wind turbines are mainly divided into horizontal axis wind turbines and vertical axis wind turbines. At present, horizontal axis wind turbines occupy the mainstream position in the market. Broadly speaking, it is a thermal energy utilization engine that uses the sun as the heat source and the atmosphere as the working medium. Wind power generation uses natural energy, which is worse than diesel power generation. However, if it is used in an emergency, it is still not as good as a diesel generator. Wind power cannot be regarded as a backup power source, but it can be used for a long time

[0003] Onshore wind turbine foundations generally include concrete expansion foundations and pile foundations, but there are differences between building wind farms offshore and ordinary onshore wind farms. Ordinary onshore construction machinery and construction methods will not be used. Wind power The foundation of the generator is piled by a piling ship, and the concrete is poured by a concrete mixing transport ship. Because the foundation of the offshore wind turbine is affected by the waves, it is necessary to solve the problem of wave prevention, and at the same time, it must be convenient for construction, because the seabed is generally silty soil or silt. The soft foundation of the soil has a very low foundation bearing capacity, so it is easy to cause problems such as instability and collapse. Therefore, how to overcome the above problems and build a foundation structure for offshore wind turbines is a problem that needs to be solved urgently.

In addition, the existing wind power generators can only use wind power to generate electricity. When there is no wind at sea, they cannot generate electricity normally, and the environmental adaptability is poor. When the wind and waves are strong, the power generation device is easy to tilt or even topple over. Seawater is also easy to erode the blades of the generator, which seriously affects the normal use of the power generation device
