Description

Technical Field

[0001] The present invention relates to clean energy technology, in particular to wind power generation technology, and more specifically to a wind turbine generator device with blades that can be automatically retracted and unfolded. Background Art

[0002] As global energy demand continues to rise and environmental protection issues become increasingly prominent, wind power generation technology has gradually attracted people's attention;

[0003] Traditional breeze wind turbines primarily rely on vertical-axis wind turbines, unique in their ability to efficiently convert wind power into electricity even in light winds. These turbines can start and generate electricity at wind speeds as low as 3 m / s. However, these turbines typically have fixed blades, limiting their wind exposure area. This makes them ineffective in preventing wind damage to the turbines during high winds or extreme weather.

[0004] Therefore, it is necessary to provide a wind turbine device with blades that can be automatically retracted and unfolded to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a wind turbine device with automatically retractable and deployable blades. The blades can be deployed through a lifting mechanism and a connecting rod mechanism, providing a larger wind-receiving arm, generating electricity with breeze, and improving power generation efficiency. In the event of strong winds, the blades are retracted inward to reduce wind resistance, prevent damage to the wind turbine caused by strong winds, and effectively improve the safety of the wind turbine.

[0006] The technical solution is as follows:

[0007] A wind turbine device with automatically retractable and deployable blades comprises a generator assembly, the generator assembly being connected to a rotating shaft, a vertical rotating shaft being provided on the upper side of the rotating shaft and being capable of being raised and lowered, a lifting assembly being provided corresponding to the vertical rotating shaft, the lifting assembly being connected to a plurality of blades via a connecting rod mechanism, the connecting rod mechanism comprising a connecting rod rotatably connected to the lifting assembly at one end, the other end of the connecting rod being connected to the blades, the connecting rod being located at the top end being rotatably connected to a retractable drive connecting rod in the middle part, the other end of the retractable drive connecting rod being rotatably connected to the top end of the lifting assembly, the retractable drive connecting rod being driven by the lifting of the lifting assembly to rotate the connecting rod, thereby retracting the blades, thereby forming a wind turbine structure in which the blades can be automatically retracted and deployed.

[0008] Furthermore, the number of blades is 3.

[0009] Furthermore, each blade is connected to the lifting assembly through at least three connecting rods.

[0010] Furthermore, an electric cylinder and a guide rod are provided inside the vertical rotating shaft, the output end of the electric cylinder is connected to the guide rod, and a guide sleeve is provided corresponding to the guide rod, and the guide sleeve is connected to the lifting assembly.

[0012] Furthermore, the generator is connected to the rotating shaft through a slip ring, and a bearing seat used in conjunction with the rotating shaft is provided on the support, and the support is provided on a rotating platform provided on the base.

[0013] Furthermore, there are two generator assemblies, and a column bracket is provided for each generator assembly. A dual-drive external elevator is provided on the column bracket, and the dual-drive external elevator is connected to the lifting assembly.

[0014] Furthermore, there are four generator assemblies, the supports are arranged on the outer frame, and a four-drive external elevator is arranged on the top of the outer frame, and the four-drive external elevator is connected to the lifting assembly.

[0022] Example:

[0023] See Figure 1-3This embodiment shows a wind turbine device with automatically retractable and deployable blades, including a generator assembly 13. The generator assembly 13 is connected to a rotating shaft 5. A vertical rotating shaft 6 is provided on the upper side of the rotating shaft 5 for lifting and lowering. A lifting assembly 9 is provided corresponding to the vertical rotating shaft 6. The lifting assembly 9 is connected to a plurality of blades 10 through a connecting rod mechanism. The connecting rod mechanism includes a connecting rod rotatably connected to the lifting assembly 9 at one end, and the other end of the connecting rod is connected to the blades 10. The connecting rod at the top is rotatably connected to a storage drive connecting rod in the middle, and the other end of the storage drive connecting rod is rotatably connected to the top of the lifting assembly. When the lifting assembly is raised, the storage drive connecting rod drives the connecting rod to rotate, so that the blades 10 are retracted, forming a wind turbine structure in which the blades can be automatically retracted and deployed.

[0024] The number of blades 10 is three.

[0025] Each blade 10 is connected to the lifting assembly via at least three connecting rods.

A column bracket 16 is set corresponding to the generator assembly 13, and a dual-drive external elevator 17 is set on the column bracket 16. The dual-drive external elevator 17 is connected to the lifting assembly 9; the two symmetrically installed blades can automatically retract and unfold the wind power generation structure, so that the air inlet forms a wind gathering area, increases the wind speed reaching the blades, and improves the power generation efficiency after superimposing the speed. This design is particularly suitable for low wind speed environments.

[0031] See Figure 6 There are four generator assemblies 13 , the support 1 is set on the outer frame 18 , and a four-drive external elevator 19 is set on the top of the outer frame 18 , and the four-drive external elevator 19 is connected to the lifting assembly 9 .
