Common fan types include centrifugal fans, axial fans, mixed-flow fans, and cross-flow fans, each with different working principles and performance characteristics. Fans generate airflow power through rotating blades or impellers, thereby achieving gas transport and pressure increase. They are widely used in ventilation, air conditioning systems, dust removal and purification, and pneumatic material conveying. When selecting a fan, factors such as air volume, air pressure, speed, efficiency, and energy consumption need to be comprehensively considered, and the appropriate fan type and specifications should be selected based on actual needs, operating conditions, and economic requirements.
[0003] The disassembly process of existing wind turbines is quite complex and cumbersome, resulting in significant manpower and time costs for component replacement or repair. Especially when maintaining critical components, specialized tools and technical support are often required, which not only increases the difficulty of maintenance but may also prolong equipment downtime and affect normal operation. Furthermore, during long-term operation, the motor and rotating shaft generate a large amount of heat, which can easily lead to overheating of components, accelerate aging, and thus shorten the overall lifespan of the wind turbine.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1 and Figure 2 An embodiment of this utility model provides an easy-to-install and disassemble fan, including a frame 1, a housing 2 fixedly connected to the upper right side of the frame 1, an air inlet 3 fixedly connected to the right side of the housing 2, an air outlet 4 fixedly connected to the outer wall of the top of the housing 2, an impeller 5 disposed inside the housing 2, a first support plate 6 fixedly connected to the upper left side of the frame 1, a motor 7 fixedly connected to the upper end of the first support plate 6, a drive wheel 8 fixedly connected to the drive end of the motor 7, a transmission belt 9 disposed on the outer wall of the drive wheel 8, a driven wheel 10 disposed on the inner wall of one end of the transmission belt 9, a rotating shaft 11 fixedly connected to the inner wall of the driven wheel 10, and a cooling oil seat 12 fixedly connected to the outer wall of the rotating shaft 11.
[0026] Specifically, air is drawn in through the inlet 3, accelerated by the impeller 5 inside the casing 2, and then ejected from the outlet 4. The motor 7 provides power, driving the drive wheel 8 to rotate. The drive wheel 8 drives the driven wheel 10 to rotate via the transmission belt 9. The driven wheel 10 drives the rotating shaft 11 to rotate, and the impeller 5 rotates with the rotating shaft 11. When the rotating shaft 11 rotates at high speed, heat is generated due to friction. The oil cooler 12 contains cooling oil to cool the rotating shaft 11. The separation of the motor 7 from the rotating shaft 11 prevents the heat generated by the motor 7 from being transferred to the rotating shaft 11. The separation of the oil cooler 12 and the motor 7 from the rotating shaft 11 reduces heat transfer inside the fan and extends the service life of the fan.
[0027] Reference Figure 2 , Figure 3 and Figure 6 A second support plate 16 is fixedly connected to the lower end of the cold oil base 12. A movable plate 14 is connected to the left side of the housing via a hinge. A limit hole 15 is formed on the outer wall of the movable plate 14. A fixed block 13 is fixedly connected to the outer wall of the left side of the housing 2. A limit rod 21 is slidably connected to the inner wall of the fixed block 13. A spring 22 is provided at one end of the limit rod 21, and the other end of the spring 22 is connected to the inner wall of the fixed block 13. A handle 23 is fixedly connected to the outer wall of the limit rod 21. A sliding groove is formed on the outer wall of the fixed block 13, and the handle 23 is slidably connected to the inner wall of the sliding groove. The limit rod 21 is slidably connected to the inner wall of the limit hole 15. The second support plate 16 is fixedly connected to the outer wall of the movable plate 14. The rotating shaft 11 and the movable plate 14 are rotatably connected.
[0028] Specifically, the second support plate 16 supports the cold oil seat 12. Moving the handle 23 away from the movable plate 14 moves the limiting rod 21, compressing the spring 22. When the limiting rod 21 slides out of the limiting hole 15, the movable plate 14 can rotate via the hinge. After rotation, it drives the rotating shaft 11, driven wheel 10, and impeller 5 to rotate together. The driven wheel 10 and the transmission belt 9 separate, making the replacement of the transmission belt 9 more convenient. The impeller 5 can rotate to the outside of the casing 2, making maintenance of the impeller 5 more convenient. When the fan needs to run, the movable plate 14 is closed, and the movable plate 14 presses the limiting rod 21, causing the limiting rod 21 to move away from the movable plate 14. The limiting rod 21 compresses the spring 22. When the limiting rod 21 aligns with the limiting hole 15, the spring 22 rebounds, and the limiting rod 21 engages in the limiting hole 15, thus limiting the movable plate 14.
[0029] Reference Figure 4 and Figure 5 An inner clamping plate 17 is fixedly connected to the outer wall of the right side of the rotating shaft 11. Bolts 18 are fixedly connected to both ends of the inner clamping plate 17. An impeller 5 is provided on the outer wall of the inner clamping plate 17. An outer clamping plate 19 is provided on the right side of the impeller 5. The outer clamping plate 19 is slidably connected to the outer wall of the bolts 18. A nut 20 is provided on the outer wall of the outer clamping plate 19.
[0030] Specifically, the impeller 5 is clamped by the inner clamping plate 17 and the outer clamping plate 19, and then the inner clamping plate 17 and the outer clamping plate 19 are fixed by the bolts 18 and the nuts 20, so that the impeller 5 is fixedly connected to the right end of the rotating shaft 11. This design makes it more convenient to disassemble and install the impeller 5.
[0031] Working principle: When using this device, start the motor 7. The motor drives the drive wheel 8 to rotate. The drive wheel 8 drives the driven wheel 10 to rotate via the transmission belt 9. The driven wheel 10 drives the rotating shaft 11 to rotate. The impeller 5 then rotates with the rotating shaft 11. Air is drawn in from the air inlet 3, accelerated by the rotation of the impeller 5 inside the casing 2, and then thrown out from the air outlet 4. The rotating shaft 11 generates heat due to friction when rotating at high speed. The cooling oil seat 12 contains cooling oil to cool the rotating shaft 11. The motor 7 is separated from the rotating shaft 11, allowing the motor 7 to... The generated heat cannot be transferred to the rotating shaft 11. The second support plate 16 supports the cold oil seat 12. Moving the handle 23 away from the movable plate 14 moves the limiting rod 21, compressing the spring 22. When the limiting rod 21 slides out of the limiting hole 15, the movable plate 14 can rotate via the hinge. After rotation, it drives the rotating shaft 11, driven wheel 10, and impeller 5 to rotate together. The driven wheel 10 and the transmission belt 9 separate, making the replacement of the transmission belt 9 more convenient. The impeller 5 can rotate to the outside of the casing 2, making maintenance of the impeller 5 more convenient. When the fan needs to run, the movable plate 14 is closed, and the movable plate 14 presses the limiting rod 21, causing the limiting rod 21 to move away from the movable plate 14. The limiting rod 21 compresses the spring 22. When the limiting rod 21 aligns with the limiting hole 15, the spring 22 rebounds, and the limiting rod 21 engages in the limiting hole 15, thus limiting the movable plate 14. The impeller 5 is held in place by the inner clamping plate 17 and the outer clamping plate 19, and then the inner clamping plate 17 and the outer clamping plate 19 are fixed by the bolts 18 and the nuts 20, so that the impeller 5 is fixedly connected to the right end of the rotating shaft 11. This design makes it easier to disassemble and install the impeller 5.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
