Description

TECHNICAL FIELD

[0001] The utility model relates to fan technical field, concretely is a multifunctional liftable regulation axial flow fan device. BACKGROUND

[0002] In the production process of steel companies, ventilation equipment plays a crucial role, not only related to the comfort of the production environment, but also directly affects the production efficiency and safety. As a kind of efficient ventilation equipment, axial flow fan is widely used in various production links of steel companies because of its large air volume, moderate wind pressure, simple structure and convenient maintenance. However, the traditional axial flow fan has many limitations in installation and use process, especially in height adjustment, pitch angle adjustment and anti-toppling, which is particularly prominent in the special production environment of steel companies.

[0003] Firstly, the production site of steel companies is often complex and changeable, and different production areas have different requirements for the height of ventilation equipment. Most of the traditional axial flow fans are installed in a fixed way, and once installed, their height is difficult to adjust, which greatly limits the flexibility of fan use. Especially when ventilation is needed for different height production areas, traditional fans often cannot meet the needs, resulting in poor ventilation effect and even affecting the production process.

[0004] Secondly, the adjustment of pitch angle is also crucial to the use effect of axial flow fan. In some production links of steel companies, axial flow fan may need to be blown at a specific angle to optimize the ventilation effect. However, the pitch angle of traditional axial flow fan is usually fixed and cannot be adjusted according to actual needs, which also limits the use range and effect of axial flow fan.

[0005] Finally, the anti-toppling problem is also an important factor that needs to be considered when steel companies use axial flow fan. Because the production environment of steel companies is often harsh, there are unstable factors such as vibration and impact, combined with the possibility of fan toppling due to improper installation or accidental situations during use, which not only damages the fan equipment, but also may cause safety hazards to personnel and equipment in the production site.
