Description
Technical field:
The utility model relates generally to the structure of blower fan fin and the material of use thereof, the particularly structure of vertically-supplying air airfoil.
Background technique:
The structure of the blower fan fin of prior art mostly is the metallic material integrally stretching greatly or extrudes, also made such as useful glass fibre reinforced plastics, such tab construction efficient is low, the cost height, Heavy Weight and manufacturing process complexity are unfavorable for producing in batches and reducing product cost very much.And the more important thing is that heavy fan assembly will consume lot of energy, can not be implemented in low velocity wind and turn round.So the blower fan fin of lightweight is the target that design, manufacturing and the user of blower fan pursues always, the fin of lightweight can improve the Wind Power Utilization efficient of blower fan, the manufacture cost of reduction blower fan, but the requirement that the mechanical property of common lightweight material does not often reach the large fan fin; The mechanical property of some lightweight material (as carbon fiber glass) has reached requirement, but material and manufacture cost are too high, can't commercialize.The length of large fan fin has reached the limit of its manufactured materials performance at present, and the fin length that has is to bring with the cost that reduces safety coefficient.On the other hand, the length of fin surpasses the regulation of traffic management and the design camber of highway, also can't deliver to the erecting bed.Large-scale fin in use runs into high wind or typhoon, because its blowing area is big, very easily damages.
The model utility content:
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of Wing panels of aeration blower fan is provided.
The purpose of this utility model can be by realizing by the following technical solutions: a kind of Wing panels of aeration blower fan, include the airtight wing body of blower fan fin shape, be provided with the inflation air flue in it, its main feature is that the upper and lower part that also includes the closed shell of blower fan fin shape is provided with upper wall (1) and lower wall (7) respectively, form closed cavity with streamlined curved surface sidewall (2), be provided with dividing plate (6) in it, its inner chamber is divided into several inflating cavities (8); In inflating cavity (8), be provided with several endoporus (3), be communicated with the through hole (15) on upper wall (1) and the lower wall (7); Valve (9) is located at endoporus (3) and upward and with inflating cavity (8) is communicated with.
Described Wing panels of aeration blower fan is provided with several struts (11) in the endoporus (3) of the airtight wing body of blower fan fin shape, which is provided with air valve (10) and be communicated with valve (9) on the endoporus (3).Described Wing panels of aeration blower fan also is provided with backguy endoporus (5) in inflating cavity (8), be communicated with through hole (13) on upper wall (1) and the lower wall (7), is provided with backguy (12) in it, and an end and lower wall (7) are connected, and the other end and bobbin are connected.
The material of the Wing panels of aeration blower fan upper wall (1) of Wing panels of aeration blower fan of the present utility model and lower wall (7), strut (11) is the material of hard.The material of Wing panels of aeration blower fan sidewall (2) is a flexible material.
The airtight wing of described Wing panels of aeration blower fan is filled with gas, can be air, helium, hydrogen, nitrogen, argon gas, carbon dioxide or their mixed gas, makes airtight wing body bulging form satisfactory shape.
Wing panels of aeration blower fan comprises that also the two ends of described strut (11) are provided with the link hinged with the sail combination support (14).On strut (11), be provided with a plurality of suction valves (10), airtight wing body that several blower fan fin shapes arranged corresponding with it, its valve (9) is connected with corresponding air valve (10).Sidewall (2) inboard is provided with supporting rib (4).
Wing panels of aeration blower fan is that airtight wing body can be that series, parallel or series connection are formed Wing panels of aeration blower fan with in parallel the mixing.
The beneficial effects of the utility model are, because this fin has adopted the technology of thin-walled cavity inflation, realized in light weight, materials are few, the weight that reduces fin in this enhancing process in intensity that strengthens thin-walled cavity structure fin and rigidity again to greatest extent increases, and reduces the cost of making fin.Its biggest advantage is can be according to the blowing area of the size adjustment blower fan fin of wind-force, improve fan operation efficient, can initiatively reduce simultaneously the blowing area of blower fan fin, avoid of the damage of natural disaster such as typhoon, to prolong the working life of blower fan to blower fan.Simple in structure, reasonable in design.Enough intensity is arranged, be difficult for distortion, distortion, handsome in appearance, economical with materials.Be convenient to manufacturing, transportation and the installation of blower fan, making development make bigger, more economical blower fan becomes possibility.
