Abstract
The utility model relates to a large-scale novel air-cooled fan blade comprising an upper arc plate, a lower arc plate and a streamline flange plate. Two ends of the upper arc plate and two ends of the lower arc plate are closely connected, and one end of the upper arc plate and one end of the lower arc plate are provided with a lug boss; one end of the streamline flange plate is provided with a groove, and the groove is tightly inosculated with the lug boss; a hollow space is formed between the groove and the lug boss and is internally provided with a beam shell structure and at least one reinforcing rib, wherein the beam shell structure is tightly and firmly connected with the inner wall of the hollow space and is internally provided with a cylindrical shaft which runs through the whole hollow space, and one end of the cylindrical shaft extends out of the large-scale novel air-cooled fan blade. The utility model has the advantages of light weight, high strength, strong natural wind resisting capacity, long service life, concentrated stress elimination at the joint and relatively lower cost.
Description
Technical field:
The utility model relates to a kind of fan blade, particularly a kind of large-scale novel air-cooled fan blade.
Background technique:
At present, the air-cooled fan blade of use is because unreasonable structure, and the stress of joint concentrates, and makes the anti-natural wind ability of blade undesirable, and flexible or fracture; In addition, the material of making blade is perfect inadequately, causes the Heavy Weight of fan blade, intensity low; And the fan blade long term exposure is exposed to the sun and rain in air, thereby just easily aging working life is shorter, also can influence the operation of generator set during replacing, causes bigger economic loss.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, provide a kind of in light weight, intensity is high, anti-natural wind ability strong, the large-scale novel air-cooled fan blade of long service life.
The purpose of this utility model is achieved through the following technical solutions: a kind of large-scale novel air-cooled fan blade, comprise arc plate, arc lower plate and streamline wing plate, the described arc plate of going up closely links to each other with arc lower plate two ends, and an end is boss, and described streamline wing plate one end is provided with groove, and with the boss tight connecting, strengthened anti-natural wind effect, this blade adopts import high strength unsaturated resin material and noble metal raw material and advanced industrial chemicals to make, and overall weight is lighter relatively; The described middle hollow space that forms that goes up arc plate and arc lower plate is provided with three stiffening ribs and beam shell structure body in the hollow space, guaranteed the usage requirement of generous type fan blade; Beam shell structure body and hollow space inwall are fastenedly connected; Stiffening rib is made by virtue, platinum complex fiber material and interpolation noble metal raw material and advanced industrial chemicals, through infiltration, mold pressing, thermosetting, pressurize maintenance moulding, makes its tension strength reach 560Mpa, impact strength 90kj/m2, hardness Barcol 51 degree; Arc plate, arc lower plate and streamline wing plate surface are equipped with protective layer on blade, and protective layer is made by the thick nanometer weatherable materials of 0.5mm, and this product anti-aging time limit in the environment of 40 degrees below zero Celsius 120 degree extremely Celsius was reached more than 30 years; Be provided with cylinder axis in beam shell structure body, described cylinder axis runs through whole hollow space, and an end stretches out in hollow space, is used to connect wheel hub, and the stress that can eliminate the joint is concentrated.
The utility model compared with prior art has the following advantages: in light weight, intensity is high, anti-natural wind ability is strong, long service life, and eliminate joint stress and concentrate, relative cost is lower.
