Description
Technical field
This utility model relates to one and Industrial fan field, particularly to a kind of fan blade profile material。
Background technology
In the industrial production, the large space working environments such as factory generally adopt large-scale industrial fan be aerated and lower the temperature, the air-flow formed during the operating of major diameter Industrial fan pushes down on, the air-flow of horizontal direction is produced after running into ground, the size of Diffusion of gas stream is relevant with the diameter of fan, the speed of Diffusion of gas stream is then relevant with the speed that flabellum rotates, if fan continuously runs, air-flow will outwards elapse in a large number, until rising therewith after running into side wall or barrier, thus continuously constituting air circulation。Rotation speed of the fan is too high, and the air-flow of generation will strengthen, and so has by the sensation of wind blow-through, and human body can be made to produce sense of discomfort, and too high wind speed also can make people dizzy；If rotating speed is too low, then wind-force is powerful not, and the center of flabellum differs greatly with the wind-force of edge placement during due to use, discontinuity, if Industrial fan rotating speed is higher, then can accelerate the appearance of metal fatigue phenomenon, flabellum can descend bending deformation to become big year by year, until root can not bear own wt and rupture, only body surface heat is distributed and organically combine with wind speed, the nice and cool sensation of appropriateness could be produced。Industrial fan adopts the mode slowly rotated, and forms in an unbroken line mild wind, in order to improve fan efficiency, reduces energy consumption, it is necessary to flabellum shape is optimized。
Summary of the invention
The purpose of this utility model is in that to solve the deficiencies in the prior art, and this utility model provides a kind of simple in construction, intensity is high, work efficiency is good, the uniform fan blade profile material of wind-force。
This utility model solves its technical problem and be the technical scheme is that a kind of fan blade profile material, and including flabellum body, described flabellum body is strip, and the axial both sides of flabellum body have the axially extended closed angle end along flabellum body and rounded end；The cross section of described flabellum body is the reclinate arc of closed angle end, and the reclinate angle of closed angle end of described flabellum body is 15 °～20 °；This internal cavity being provided with axially through flabellum body two ends of described flabellum, is provided with a pair along the axially extended reinforcement of flabellum body in described cavity, upper and lower for flabellum body both sides are connected by described reinforcement；Described have connecting groove on the reinforcement of rounded end side, on the downside of the flabellum body of described cavity inherence, one end is provided with connecting platform, on the upside of the flabellum body of described cavity inherence, side corresponding with connecting platform is provided with connecting hole, the inserted slot that the described reinforcement towards closed angle end side is connected with blower fan with formation one between connecting groove, connecting platform, connecting hole。
As preferably, the thickness of described flabellum body intermediate ends is more than the thickness of closed angle end, rounded end。
As preferably, the reclinate angle of closed angle end of described flabellum body is 18 °。
As preferably, described connecting hole is two。
The dual-side respectively closed angle end of the flabellum body of fan blade profile material described in the utility model, rounded end, and its cross section is the reclinate arc of closed angle end, and the reclinate angle of closed angle end is 18 °, flabellum body is made to reduce air drag in rotation process, enhance work efficiency good so that wind-force is more uniformly distributed；Owing to flabellum body interior is provided with cavity, thus reducing the weight of flabellum body, and in cavity, be provided with a pair reinforcement, make flabellum body weight relatively low be maintained with good intensity；On the reinforcement of rounded end side, it is provided with connecting groove in cavity, it is also provided with connecting platform, connecting hole, towards forming the inserted slot being connected with blower fan between the reinforcement of closed angle end side with connecting groove, connecting platform, connecting hole, improve the connective stability between flabellum body and blower fan。
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of this utility model embodiment。
Detailed description of the invention
Below by specific embodiment, and in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail。
Embodiment:
