Abstract

The invention discloses a wind-resistant dome for an offshore wind turbine, and belongs to the technical field of installation of wind turbine domes. A dome body is provided with installing ports. Theinstalling ports are fixedly provided with rotating blades. A flange fixing base is integrally formed and fixedly installed on each installing port. The end, installed on the dome body, of each rotating blade is fixedly connected with an assembly flange. The dome body is fastened and connected with the rotating blades through the assembly flanges and the flange fixing bases. The invention furtherprovides a structural diagram of fixing assemblies between the flange fixing bases and the assembly flanges. The fixing assemblies improve the stability between the rotating blades and the dome body,fastening assemblies are further arranged in the dome body, the assembly traction among the rotating blades is realized through the fastening assemblies, the stability between the rotating blades andthe dome body is further improved, and therefore the wind-resistant property of the dome is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of installation of a wind turbine wind deflector, and in particular relates to a wind-resistant wind deflector for an offshore wind power generator. Background technique [0002] The wind turbine nacelle cover is a kind of outer shell used on the wind power generator to facilitate the installation of the generator. The generator is installed inside the nacelle cover, and the wind energy is converted into electrical energy through the rotation of the rotating blades, which is convenient for people to use. Due to the amount of electricity used in our country Huge, and wind power generation is currently a relatively mature environmental protection production capacity technology. Therefore, wind power generators are widely used in my country, and the amount of use is huge, and they are generally welcomed by people; [0003] In the prior art, the wind power generator includes a nacelle cover and a wind deflector. ...
