Description

Technical Field

[0001] This utility model relates to the technical field of wind power generation accessories, specifically to a corrosion-resistant blade for wind power generation. Background Technology

[0002] With the continuous growth of global energy demand and the increasing awareness of environmental protection, wind power, as a clean and renewable energy source, has received widespread attention and application. As one of the core components of a wind turbine, the performance and quality of the wind turbine blade directly affect its power generation efficiency and operational stability. However, existing wind turbine blade technology still has some significant shortcomings and deficiencies. First, traditional blade materials often struggle to balance strength and corrosion resistance, making the blades susceptible to erosion from environmental factors such as rainwater, salt, and ultraviolet radiation during long-term use, thus affecting their service life and performance. Second, traditional blade connection methods often suffer from unstable connections and loosening, which not only affects the power generation efficiency of the wind turbine but may also pose safety hazards. Furthermore, existing blade replacement methods are often cumbersome, requiring significant manpower and time, increasing operation and maintenance costs. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0029] A corrosion-resistant blade for wind power generation, such as Figures 1-3As shown, the wind turbine includes a wind turbine housing 10 and a rotating turbine head 30 installed at the end of the wind turbine housing 10. Several sets of evenly spaced replaceable blades 20 are installed on the outer wall of the rotating turbine head 30. Each replaceable blade 20 includes an inner core 201 and a crash-resistant outer shell 203. A reinforcing filler layer 202 is provided between the inner core 201 and the crash-resistant outer shell 203. The reinforcing filler layer 202 includes several crisscrossing reinforcing ribs 21 and a composite filler layer 24. The surface of the crash-resistant outer shell 203 is provided with corrosion-resistant materials. Layer 204, with several sets of evenly spaced replaceable blades 20 on the outer wall of the rotating head 30, improves wind power generation efficiency; the reinforcing filling layer 202 between the inner core 201 and the anti-collision outer shell 203, in which several crisscrossing reinforcing ribs 21 and composite filler layer 24 work together to significantly enhance the strength and stability of the blades; the anti-corrosion layer 204 on the surface of the anti-collision outer shell 203 effectively resists corrosive factors in the external environment and extends the service life of the blades.

[0030] Furthermore, the end of the wind turbine housing 10 furthest from the rotating head 30 is vertically connected to a support frame 40, which enables the wind turbine housing 10 to be stably installed on the ground or other supporting structures, providing a stable support foundation for the entire wind turbine.

[0031] Specifically, a connector 22 is provided at one end of the replaceable blade 20 that connects to the rotating head 30. The connector 22 is vertically inserted into the outer wall of the rotating head 30, which allows the replaceable blade 20 to be installed and removed quickly and easily, facilitating subsequent maintenance and replacement work.

[0032] The outer wall of the connector 22 is provided with several sets of fixing holes 23. The end of the rotating head 30 is equipped with a locking bolt 50 that is compatible with the size of the fixing holes 23 and is threaded, which enhances the connection stability between the replaceable blade 20 and the rotating head 30 and prevents the blade from loosening or falling off during rotation.

[0033] It is worth noting that the reinforcing rib 21 uses fiberglass or carbon fiber reinforcing ribs with a diameter of 5-10mm, which significantly improves the strength and rigidity of the blade and enables it to withstand greater wind force and torque.

[0034] It is worth noting that the composite filler layer 24 is a polyamide filler layer or a high-performance fiber-reinforced composite filler layer, and its thickness is greater than the diameter of the reinforcing rib 21, which enhances the overall strength and impact resistance of the blade and improves the service life of the blade.

[0035] In addition, the anti-corrosion layer 204 is made of epoxy resin coating, polyurethane coating or fluorocarbon coating, and the coating thickness is 0.25-1mm. It effectively resists corrosive factors in the external environment, such as rainwater, salt, ultraviolet rays, etc., protects the surface of the blade from corrosion, and extends the service life and appearance quality of the blade.

[0036] The working principle of the corrosion-resistant blades of this wind turbine:

[0037] First, the wind turbine housing 10 is securely installed in the predetermined position using the support frame 40 to ensure that the entire wind turbine can operate smoothly; then, the connector 22 of the replaceable blade 20 is vertically inserted into the outer wall of the rotating head 30 to ensure that the connection between the blade and the rotating head is firm and reliable.

[0038] After the connection is completed, the locking bolt 50 at the end of the rotating head 30 is threaded to the fixing hole 23 on the outer wall of the connector 22 to further strengthen the connection between the blade and the rotating head and prevent it from loosening or falling off under the action of wind.

[0039] Subsequently, the wind turbine is started, and the rotation of the turbine head 30 will drive the replaceable blades 20 to start rotating, using wind energy to convert into electrical energy; during long-term operation, due to the protective effect of the anti-corrosion layer 204, the surface of the blades can resist the corrosive factors of the external environment, extending their service life.

[0040] When the blades need to be replaced due to long-term use or accidental damage, simply loosen the locking bolt 50 and pull the connector 22 off the rotating head 30 to easily and quickly replace the blades.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
