[0002] Wind turbines are devices that generate electricity using wind energy. Generally, the blades of traditional wind turbines rotate according to wind speed, thereby driving the generator to produce electricity. However, this traditional blade design has some problems. For example, when the wind speed is too high, the rotation speed of the blades will increase, leading to blade damage or generator failure. This design cannot efficiently utilize wind energy in low wind speed environments, and wind speeds that are too fast or too slow can also damage the generator. In addition, rotating blades can also pose safety hazards to birds, people, and even surrounding facilities. Utility Model Content

The static blades in this invention do not rotate under wind conditions, but instead drive the generator to rotate via a wind turbine assembly, thereby generating electrical energy. Simultaneously, the air intake can be intelligently adjusted, enabling efficient utilization of wind energy under different wind speeds while also protecting the generator.
[0004] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

As can be seen from the figure, the static blade 1 is trumpet-shaped, preferably with four blades, which are arranged sequentially at intervals along the center of the four blades, namely blade one 11, blade two 12, blade three 13, and blade four 14. The diameter of the four blades is set to blade one 11 < blade two 12 < blade three 13 < blade four 14. With this configuration, the static blade 1 can efficiently utilize wind energy in low wind speed environments by gathering wind and pressurizing it layer by layer between the four blades.
[0034] In another preferred embodiment of this utility model, the static blade wind turbine with intelligent louver control of air intake further includes a power generation device 10, such as... Figure 4 As shown, the power generation device 10 is installed inside the air duct 3, and the power generation device 10 is arranged along the wind direction of the length of the air duct 3; by Figure 1 It can be seen that the air duct 3 is a cylindrical hollow tube body, slightly thinner in the middle, with the front port diameter greater than the rear port diameter. The front end of the air duct 3 is set as an air inlet, and the rear end of the air duct 3 is set as an air outlet. With this configuration, the air duct 3 forms a wind tunnel effect.
[0035] In another preferred embodiment of this utility model, such as Figure 4 As shown, the power generation device 10 includes a wind turbine assembly 7, a motor 8, and a transmission belt 9; the wind turbine assembly 7 is located at the center of the airflow hole of the blade 4 14, and the motor 8 is located at the center of the airflow hole of the diffuser 4. The wind turbine assembly 7 and the motor 8 are rotatably connected through the transmission belt 9; the wind turbine assembly 7 drives the motor 8 to operate and generate electricity through wind power.
[0036] In another preferred embodiment of this utility model, by Figure 2 It is known that the wind turbine assembly 7 includes a first gear 71, a second gear 72, a fixed rod 73, and a paddle 74; the paddle 74 is evenly distributed on the outer ring of the rotating shaft of the wind turbine assembly 7, and the shape and number of the paddle 74 are not limited in this utility model. The fixed rod 73 is located at the center of the wind turbine assembly 7 and extends beyond the wind turbine assembly 7 to be fixedly connected to the inner wall of the wind duct 3. The first gear 71 and the second gear 72 are respectively provided at both ends of the fixed rod 73.
[0037] like Figure 3 As shown, in another preferred embodiment of this utility model, the motor 8 is a dual-shaft extension motor, including a third gear 81 and a fourth gear 82; this configuration can effectively utilize wind energy and increase power generation efficiency.

It can be understood that the power monitoring unit monitors the rated operating power of the motor 8, and the wind speed monitoring unit monitors the airflow speed of the blades 14. The system automatically controls the opening angle of the intelligent louvers to obtain the optimal air intake volume. For example, if the power monitoring unit detects that the power generation is low or the wind speed monitoring unit detects that the wind force is low, the control system 141 automatically increases the opening angle of the intelligent louvers to enable the wind turbine assembly 7 to obtain more wind energy driving force. If the power exceeds the rated power of the motor 8 or the wind force is high, the control system 141 automatically decreases the opening angle of the intelligent louvers to enable the wind turbine assembly 7 to obtain better wind energy driving force.
