[0002] With the increasing demand for clean energy in society, wind power has received widespread attention as an important way to utilize renewable energy. Multi-bladed aluminum wind turbines have important application value in the field of wind power generation due to their unique structure and performance characteristics. They are composed of multiple aluminum blades, usually arranged in a ring, and convert wind energy into mechanical energy through aerodynamic principles, thereby driving a generator to generate electricity.

[0003] Chinese Patent Publication No. CN 212536226 U discloses an integrated unidirectional wind turbine structure, including a wind turbine blade assembly, a cover plate, and a connector. The wind turbine blade assembly consists of multiple wind turbine blades arranged in a ring. The wind turbine blade assembly includes an upper end face and a lower end face, and the cover plate is disposed on the upper end face of the wind turbine blade assembly. The multiple wind turbine blades are vertically arranged and together with the cover plate form a groove-shaped structure. The cover plate is a circular plate structure, and the connector is embedded in the middle of the circular plate structure, and the connector and the cover plate are integrally formed. In this invention, the wind turbine structure, with the connector and cover plate integrally formed, greatly saves costs and is easy to install. Moreover, in this invention, the wind turbine blades can be twisted, allowing air to enter in a sequential manner, so that when the wind turbine rotates, the airflow presents a turbine rotation form, resulting in better performance and greater practicality.

[0004] The existing technical solutions mentioned above have the following shortcomings: the wind turbine blades of the technical solutions are vertically arranged and form a groove-shaped structure with the cover plate. Although the twisted arrangement of the blades can make the airflow rotate like a turbine, once the blades are damaged, the entire wind turbine blade assembly needs to be replaced, resulting in high maintenance costs and room for optimization. Therefore, it is necessary to design a detachable multi-bladed aluminum wind turbine to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1-7 One embodiment of this utility model provides: a detachable multi-blade aluminum impeller, including an upper limit plate 1 and an upper guide pad 2, wherein the bottom end of the upper limit plate 1 is connected to the upper guide pad 2.

[0025] Limiting holes 8 are evenly arranged inside the upper limit plate 1. The bottom end of the upper guide pad 2 is connected to the blade body 3, and the bottom end of the blade body 3 is connected to the lower guide pad 4. Guide openings 9 are evenly arranged inside the upper guide pad 2.

[0026] The top of the blade body 3 is fixedly connected with a first mounting tooth 10, and the bottom of the blade body 3 is fixedly connected with a second mounting tooth 11. The interior of the lower guide pad 4 is uniformly provided with mating grooves 12, the outer side of the lower limit plate 5 is uniformly provided with mounting grooves 13, and the lower limit plate 5 is provided with a second fixing hole 14.

[0027] Specifically, such as Figure 4 and Figure 5 As shown, during use, the blade body 3 is effectively fixed in both the radial and axial directions by the limiting action of the upper limit plate 1 and the lower limit plate 5, as well as the guidance and cooperation of the upper guide pad 2 and the lower guide pad 4, which enhances the overall stability of the wind turbine and reduces swaying and vibration during operation. This design allows the blade body 3 to be easily disassembled and replaced, reducing maintenance costs. The design of the guide port 9 and the mating groove 12 makes the installation of the blade body 3 more convenient and improves assembly efficiency.

[0028] The upper limit plate 1 has first fixing holes 7 evenly arranged inside, and the first fixing holes 7 are evenly distributed on the upper limit plate 1.

[0029] Specifically, such as Figure 1 and Figure 7 As shown, during use, the bolts are arranged at equal intervals through the first fixing holes 7, which allows the stress to be evenly distributed during installation, avoiding local stress concentration, improving the reliability and service life of the structure. The bolt connection method makes it easier to disassemble and reinstall the upper limit plate 1 and the upper guide gasket 2, and facilitates the maintenance and repair of the wind turbine.

[0030] The upper limit plate 1 and the upper guide pad 2 are connected by the first bolt 6, and the first bolt 6 is provided with seven sets;

[0031] The cross-section of the first mounting tooth 10 is mountain-shaped, and the first mounting tooth 10 is engaged with the limiting hole 8.

[0032] Specifically, such as Figure 1 , Figure 3 and Figure 6As shown, during use, the connection between the upper limit plate 1 and the upper guide pad 2 is more secure through the multi-point fixing of the seven sets of first bolts 6, which enhances the structural stability of the entire wind turbine and reduces the shaking and vibration during operation. The snap-fit ​​design of the first mounting tooth 10 of the mountain-shaped profile and the limiting hole 8 can effectively prevent the blade body 3 from loosening or shifting when rotating at high speed, ensuring the reliable operation of the wind turbine. The bolt connection method makes it easier to disassemble and reinstall the upper limit plate 1 and the upper guide pad 2, which is convenient for the maintenance and repair of the wind turbine. At the same time, the snap-fit ​​of the blade body 3 with the first mounting tooth 10 and the limiting hole 8 also makes it easy to replace the damaged blades individually.

[0033] The bottom end of the lower limit plate 5 is connected to a second bolt 15, and the top end of the second bolt 15 is connected to the lower guide washer 4.

[0034] The guide opening 9 has a rectangular cross-section and is arranged in a ring shape on the inner side of the upper guide pad 2.

[0035] Specifically, such as Figure 1 , Figure 2 and Figure 6 As shown, during use, the second bolt 15 connects the lower limit plate 5 and the lower guide pad 4, enhancing the structural stability of the entire wind turbine and ensuring that the components will not loosen or shift during high-speed rotation. The rectangular cross-section and annular arrangement of the guide port 9 enable the blade body 3 to be quickly and accurately aligned during installation. The annular arrangement of the guide port 9 ensures that the blade body 3 is evenly distributed, optimizing the aerodynamic performance of the wind turbine and allowing the wind force to act more evenly on the blades, thereby improving the rotational efficiency of the wind turbine.

[0036] Working principle: When this utility model is in use, when wind or airflow acts on the blade body 3, the blade body 3 converts aerodynamics into rotational motion through its shape and angle, driving the entire wind turbine to rotate. The upper guide pad 2, the lower guide pad 4, the upper limit plate 1, and the lower limit plate 5 are fixed by the first bolt 6 and the second bolt 15, ensuring that the blade body 3 is installed stably and is easy to disassemble, thus achieving the stability of the wind turbine during rotation and the convenience of maintenance.
