Technical field
The utility model relates to a kind of flabellum, particularly relates to a kind of novel flabellum being exclusively used in large-scale fan.
Background technique
Large-scale fan is ventilation conventional in the large space working environments such as factory and cooling system, the running of major diameter Industrial fan makes the air-flow of formation promote downwards, if fan operates continuously, air-flow will outwards be passed in a large number, until rise after running into side wall or obstacle, thus continuously form air circulation thereupon; If the air-flow that fan produces is excessively strong, have the sensation of directly being blown by wind, human body can be made to produce uncomfortable feeling, too high wind speed also can make people dizzy, only has and is distributed and wind speed combination by body surface heat, could produce the nice and cool sensation of appropriateness; Industrial fan adopts the mode of slow circumvolve, forms in an unbroken line gentle breeze, in order to improve fan efficiency, reducing energy consumption, being optimized flabellum shape; As the Chinese patent literature CN202493492U(day for announcing: on October 17th, 2012) disclose a kind of flabellum of Novel streamlined, although this flabellum effectively can improve fan efficiency, lower energy consumption, but this structure exists following shortcoming: one, blade face is too narrow, wind-force impression cannot keep the long time; Two, bending degree is little, dripping water type equivalence rate variance; Three, flabellum intensity difference, easily causes the fatigue that root connects; In addition, traditional flabellum and empennage mostly are and are welded and fixed, and empennage mostly is slab construction; When changing flabellum, because empennage dismounting is inconvenient, usually needs empennage to change in the lump, causing waste of material, too increase the cost of product.
Model utility content
The utility model, in order to make up the deficiencies in the prior art, provides a kind of novel flabellum, and this flabellum can keep wind-force sense effectively for a long time, improves dripping water type efficiency; Good flabellum intensity can also be kept simultaneously; Realize good empennage and change effect;
For achieving the above object, the technological scheme that the utility model is taked is:
A kind of novel flabellum, comprise flabellum body, described flabellum body is long strip, is provided with cavity, it is characterized in that: be provided with stiffening rib in described cavity in described flabellum body; Described flabellum body is wing blade; The end of described flabellum body is provided with positioning hole;
Further improvement, described stiffening rib comprises three I type muscle, i.e. the first stiffening rib, the second stiffening rib and the 3rd stiffening rib; With described second stiffening rib for matrix, described first stiffening rib and the 3rd stiffening rib are separately positioned on the both sides of the second stiffening rib; Described 3rd stiffening rib is arranged on the right side of the second stiffening rib, and arranges near the closed angle end of flabellum body; Described first stiffening rib is arranged on the left side of the second stiffening rib, and arranges near the second stiffening rib;
Further improvement, the spacing of described first stiffening rib and the second stiffening rib is 14mm;
Further improvement, described stiffening rib comprises a H type stiffening rib and an I type stiffening rib; Described I type stiffening rib is arranged on the right side of H type stiffening rib, and arranges near the closed angle end of flabellum body;
Further improvement, the width of described H type stiffening rib is 14mm;
Further improvement, the width of described flabellum body is 153.5mm;
Further improvement, described positioning hole is for ease of empennage and flabellum screw connecting thread de through hole;
Further improvement, described positioning hole is gravity center hole;
Compared with prior art, adopt such scheme, the beneficial effects of the utility model are: flabellum of the present utility model adopts the Widening Design of wing blade, make that wind-force sense keeps more lasting, cooling effect is more obvious; Meanwhile, wing blade structure is tending towards lancet structure, and this structure can make the efficiency such as dripping water type improve more than 30%; The composite structure of three I type stiffening ribs or a H type stiffening rib and an I type stiffening rib is provided with in cavity; More strengthen the intensity of self of flabellum, and then minimizing affects on the fatigue of heel part; Install for ease of empennage, end increases the project organization of positioning hole, and this structure adopts center of gravity hole structure, effectively maintains stress equilibrium during flabellum running.

Reference character:
1, positioning hole; 2, flabellum body; 3, the first stiffening rib; 4, the second stiffening rib; 5, the 3rd stiffening rib; 6, H type stiffening rib; 7, the U-shaped stiffening rib of ear;
embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment one:
As shown in Figure 1 and Figure 2, a kind of novel flabellum, comprises flabellum body 2, described flabellum body 2 is long strip, is provided with cavity in described flabellum body 2, and this cavity runs through and flabellum body 2 two ends along axis, the weight of the flabellum body 2 that cavity makes reduces, and saves the operation energy consumption of fan;
Stiffening rib is provided with in described cavity; Stiffening rib comprises three I type muscle, i.e. the first stiffening rib 3, second stiffening rib 4 and the 3rd stiffening rib 5; With described second stiffening rib 4 for matrix, the 3rd stiffening rib 5 is arranged on the right side of the second stiffening rib 4, and arranges near the closed angle end of flabellum body 2; Described first stiffening rib 3 is arranged on the left side of the second stiffening rib 4, and arranges near the second stiffening rib 4; Described first stiffening rib 3, second stiffening rib 4 and the 3rd stiffening rib 5 all extend along the axis of flabellum body 2, and are connected upper and lower for cavity both sides, and the spacing of the first stiffening rib and the second stiffening rib is 14mm; I.e. L=14mm;
It is compacter that this width is that stiffening rib coordinates, and the combination of three stiffening ribs enhances the self-strength of flabellum and the fracture resistance of flabellum body 2 more, and then decrease and affect the fatigue of heel part;
