In order to solve the problem, the utility model provides a kind of anti-turbulent fan blade.The technical program is by protective coating before leading edge portion and rear edge part are arranged and rear defence sheath, avoid blower fan in the process used, outside dust storm, the factors such as moisture are corroded the leading edge portion of anti-turbulent fan blade and rear edge part and destroy, and then ensure that the anti-leading edge portion of turbulent fan blade and the complete of rear edge part and level and smooth, reducing the damping constant of anti-turbulent fan blade, there is turbulent situation in the leading edge portion and the rear edge part that avoid anti-turbulent fan blade; Meanwhile, the technical program also further improves the join strength of upper shell and lower shell body, improves the working life of anti-turbulent fan blade.
The anti-turbulent fan blade of one in the utility model, is characterized in that having the upper shell on forward position and rear edge, has the lower shell body on forward position and rear edge, connects web; Described upper shell and described lower shell body are interconnected and around formation cavity, described connection web is positioned at described cavity and is connected with described upper shell and described lower shell body respectively; The forward position of described upper shell and the forward position of described lower shell body are interconnected to form the leading edge portion of described anti-turbulent fan blade, and the rear edge of described upper shell and the rear edge of described lower shell body are interconnected to form the rear edge part of described anti-turbulent fan blade; Described leading edge portion has front protective coating.
In such scheme, described front protective coating, along the axis of described anti-turbulent fan blade, is coated with and is contained on the outer surface of described leading edge portion.
In such scheme, described front protective coating is colloidal structure.
In such scheme, described rear edge part has rear defence sheath, described rear defence sheath along the axis of described anti-turbulent fan blade, on the application outer surface that edge is divided in the rear.
In such scheme, described rear defence sheath is colloidal structure.
Advantage of the present utility model and beneficial effect are: the utility model provides a kind of anti-turbulent fan blade, avoid blower fan in the process used, outside dust storm, the factors such as moisture are corroded the leading edge portion of anti-turbulent fan blade and rear edge part and destroy, and then ensure that the anti-leading edge portion of turbulent fan blade and the complete of rear edge part and level and smooth, reducing the damping constant of anti-turbulent fan blade, there is turbulent situation in the leading edge portion and the rear edge part that avoid anti-turbulent fan blade; Also improve the join strength of upper shell and lower shell body, improve the working life of anti-turbulent fan blade.
