Problems solved by technology

On the other hand, the length of the fin exceeds the regulations of traffic management and the design curvature of the road, and it cannot be delivered to the installation site.
When the large fins are in use, encounter strong wind or typhoon, due to their large wind receiving area, they are easily damaged

Embodiment 1

[0017] Embodiment 1, see Fig. 1, inflatable blower airfoil, has airtight wing body of fan airfoil shape, is provided with inflatable air channel in it, is respectively provided with upper wall 1 on the upper and lower part of the airtight housing of fan airfoil shape And the lower wall 7, forms a closed cavity with the streamlined curved side wall 2, and a partition plate 6 is arranged in it, and the inner cavity is divided into two inflatable cavities; two inner holes 3 are arranged in the inflatable cavity , communicating with the through hole 15 on the upper wall 1 and the lower wall 7; two air nozzles 9 are set on the inner hole 3 and communicate with the corresponding inflatable cavity 8. Two support rods 11 are arranged in the inner hole 3, two air valves 10 are arranged on the support rods 11, and communicate with the corresponding air nozzles 9, and the inner hole 5 of a pull wire is also provided in the middle of the inflatable cavity, and the inner hole 5 is arranged ...

Embodiment 2

[0018] Embodiment 2, see FIG. 2 and FIG. 3 , an air valve is provided on the support rod 11 to communicate with the corresponding three airtight wing bodies in the shape of fan blades. The structure of each fin is the same as the above-mentioned embodiment. In order to realize that the fins of a large fan can be made by connecting three inflatable fins, the area of ​​the fan fins can be increased, and the power of the fan can be improved. The air blower blade is provided with 2 support rods 11 in the inner hole 3 of the fan blade-shaped airtight wing body, and one of them is provided with 6 air valves 10 to communicate with 6 air nozzles 9 on the inner hole 3 . Also be provided with backguy inner hole 5 in the air-filled cavity, communicate with the through hole on the upper wall 1 and the lower wall 7, be provided with backguy 12 in it, one end is connected with lower wall 7, and the other end is connected with bobbin.

Embodiment 3

[0019] Embodiment 3, see Fig. 4, the upper wing is composed of two closed wing bodies A and B connected in parallel to form a complete wing shape, and connected in series with the lower two closed wing bodies to form a complete wing together.

[0020] The material used in the above three embodiments, the material of the upper wall 1 and the lower wall 7 of the air blower blade of the air blower blade is fiberglass, and the material of the support rod 11 is aluminum alloy. The material of the air blower blade side wall 2 is a flexible chemical fiber material. The inflation gas in the blades of the inflation fan is helium whose specific gravity or density is lower than that of air.

[0021] When in use, inflate through the inner hole of the support rod 11, and each fin can be inflated and connected on site, which can not only solve the transportation problem of the ultra-long fins of large wind turbines at present, but also reduce the manufacturing, transportation and installati...

Abstract

A fan panel charged with air is featured as setting top wall and bottom of sealed shell in form of fan panel and using said walls and side wall with streamline curve surface to form sealed cavity, applying isolation plate to divide it to be a numbers of air charging cavities and setting a numbers of internal holes in said cavity connect to them to through hole on top and bottom walls, installing air mouth on internal hole and connecting it to air charging cavity.

Description

Technical field: [0001] The invention mainly relates to the structure of fan blades and the materials used therefor, especially the structure of vertical fan blades. Background technique: [0002] Most of the structures of fan blades in the prior art are integral stretched or extruded metal materials, and are also made of glass fiber reinforced plastics and other materials. Such blade structures have low efficiency, high cost, heavy weight and complicated manufacturing process, which is not conducive to mass production. production and reduce product costs. What's more important is that the heavy fan assembly consumes a lot of energy, and it cannot be operated in low-speed wind. Therefore, lightweight fan blades have always been the goal pursued by the design, manufacture and users of wind turbines. Lightweight blades can improve the wind energy utilization efficiency of the fan and reduce the manufacturing cost of the fan. However, usually the mechanical properties of light...
