Description

Vertical Axis Wind Turbine

technical field

The utility model relates to the technical field of manufacturing a wind power generating device.

Background technique

Common vertical axis wind turbines use long cantilever structures. Usually the length of the cantilever is more than 1200mm, which is an unstable structure. In strong windy weather, the unstable working state of the long cantilever easily deforms the main shaft.

Since the usual vertical wind turbines adopt a double-bearing structure, that is, radial bearings and plane bearings, the self-friction of the double bearings is relatively large and the influence of the coaxiality accuracy makes the entire mechanism consume a large amount of power during its operation. , directly resulting in a decline in its work efficiency.

Since the usual vertical wind turbine adopts a cantilever structure, the installation of the wings adopts an upper and lower two-layer support structure. From the perspective of this structure alone, its stability is acceptable, but due to various conditions, its own strength is not easy to do too much. Strong, usually the cantilever of the supporting mechanism is deformed and bent, which affects the service performance and life of the equipment, and the assembly process of the mechanism on site is poor, and the labor intensity of the workers is high.

Utility model content

In order to solve common problems such as unstable structure of wind power generators, large self-friction force, poor assembly process, etc., the utility model provides a vertical axis wind power generation device.

The utility model includes a generator, a main shaft, a wing mounting seat assembly, an upper centering seat, a lower centering seat, a bearing, a transmission shaft assembly, a brake disc assembly, a generator mounting flange, and a frame assembly. The generator flange is connected to the machine base assembly, the transmission shaft assembly is arranged above the generator, the main shaft is concentrically nested in the transmission shaft assembly, and the edge of the transmission shaft assembly is connected to the brake disc assembly, a hydraulic brake assembly is set on the edge of the brake disc assembly, the lower end of the wing mounting seat assembly is fixedly connected to the transmission shaft assembly, and the upper end of the main shaft is set on the wing mounting assembly Inside, the bearing is arranged between the main shaft and the wing mounting assembly, the lower centering seat is set at the center of the upper end of the main shaft, and the upper centering seat is set at the center of the upper end of the wing mounting seat assembly. A steel ball is arranged in the space formed by the upper centering seat and the lower centering seat, and at least two wing supports are connected axially symmetrically in the middle of the wing mounting seat assembly, and the other end of each wing support is connected to the wing fixture In the middle part of the assembly, each wing clamp assembly is fixedly connected with a wing respectively.

In the utility model, the length of the main shaft of the wing mounting seat is designed to be 300-400 mm, so that the structural stability of the whole machine is greatly enhanced, and the bending of the main shaft in strong wind weather is avoided; the radial transmission of the vertical axis wind power generator is Radial bearing, axial transmission is steel ball. Because the friction force of a single steel ball is smaller than that of a plane bearing during the transmission process, the power consumed by the entire mechanism during its operation is smaller than that of a common vertical axis generator, reducing its own power consumption. This condition is more important in the vertical shaft generator; the mechanism of the utility model changes the frame structure of the existing vertical wind power generator, that is, the upper and lower layers of support, into a layer of support, and the outer ends of each wing support are connected with each The middle part of the wing is connected, and this improvement makes its own strength larger and its stability tends to be better. The use performance of the equipment is improved and the service life is prolonged, the assembly manufacturability of the mechanism is optimized, and the labor intensity of workers is reduced.

The opposite surfaces of the lower centering seat and the upper centering seat described in the utility model are respectively arc surfaces matched with steel balls.
