Description

Outer rotor vertical wind driven generator

Technical Field

The utility model belongs to the technical field of aerogenerator, concretely relates to perpendicular aerogenerator of external rotor.

Background

The vertical wind driven generator is a low-rotation-speed wind driven generator which converts wind energy into mechanical energy and then into electric energy. Wind power is used for generating electricity, and the storage battery is charged to store electric energy. The wind energy remote control system is generally suitable for areas with good wind energy conditions, far away from a power grid or abnormal power grid, and supplies electricity to illumination, televisions, searchlights, video players, communication equipment and electric tools.

In the traditional high-power vertical wind driven generator in the market, the generator part is arranged at the lower part of the wind driven generator, and the fan assembled in such a way has the following defects:

1. the fan assembly difficulty is big. When the conventional vertical wind driven generator is assembled, the conventional vertical wind driven generator must be installed step by step from bottom to top, and rework and a large amount of manpower and material resources are consumed due to low assembly precision of any group of steps;

2. the fan packing and transporting cost is high. When the conventional vertical wind driven generator is used for delivering and packaging goods, the main machine part cannot be disassembled and only can be integrally packaged, so that the packaging box is large in size and heavy in weight, and particularly, the transportation cost is too high during international transportation, so that the product competitiveness is not strong, and the cost performance is not high;

3. the maintenance of the fan consumes time and labor. Since wind power generators need to work all year round, routine maintenance of wind turbines is particularly important. The generator part is a core component of the vertical wind driven generator, the generator part of the conventional vertical wind driven generator is positioned below the fan, and when the fan generator is maintained or even damaged and needs to be overhauled, if the fan needs to be completely dismantled, the fan comprises fan blades and a bracket, so that a large amount of manpower and material resources need to be consumed in the workload;

4. the fan bracket blade connection is not firm, and the fault is easy to occur in extreme weather. As the diameter and the height of the blade of the high-power vertical shaft generator are both large, the connection part of the bracket and the host machine is in daily and long-term accumulated operation, and the mechanical fatigue is generated and the fracture is easy to occur.
