Description
Technical field
The present invention relates to no-power air blower technical field, particularly relate to the blade of a kind of no-power air blower, and apply the no-power air blower of this blade.
Background technology
In the buildings such as industrial premises, through carrying out exhaust ventilation frequently with no-power air blower. No-power air blower, it is not necessary to artificially provide power, its power is mainly derived from the thermal current of indoor rising and outdoor natural wind, by promoting the turbine main frame of blower fan to rotate, to reach the effect of ventilation. Compared with driven fan, no-power air blower has that cost is low, noiselessness, Non-energy-consumption, advantages of environment protection, and its application is widely.
The main frame of no-power air blower is the turbine structure of multiple blade composition, the lamellar that blade is curved, and multiple blades are around main shaft circumferential arrangement; The rotation normal of blade and blower fan is kept at an angle, and is kept at an angle with main shaft, as such, it is possible to make blade effectively comprehensively utilize the lift of the thermal current that air outlet rises and the horizontal thrust of outside natural wind. But, no-power air blower is owing to being subject to the impact of bearing element frictional force, and when the wind speed of the only small and outside natural wind of indoor/outdoor temperature-difference is slower, the wind pressure difference of leave dual sides is big not, then a turn degree for no-power air blower even cannot rotate very slowly.
Therefore, how the blade of no-power air blower in prior art being improved, the wind pressure to expand leave dual sides is poor, to improve the rotating speed of no-power air blower, has become as the technical problem that those skilled in the art assistant officer is to be solved.
Summary of the invention
For prior art Problems existing, it is an object of the invention to propose the blade of a kind of no-power air blower and apply the no-power air blower of this blade, the wind pressure expanding leave dual sides is poor, improves the rotating speed of no-power air blower.
For reaching this purpose, the present invention by the following technical solutions:
The blade of a kind of no-power air blower, including blade body, at the connecting portion that is respectively arranged at two ends with of blade body, blade body is highlighted along its camber line by Inside To Outside, forms convex ridge in the outside of blade body, forms groove in the inner side of blade body.
Preferably, the height of convex ridge and the degree of depth of groove are gradually reduced from the middle part of blade body to two ends.
Preferably, convex ridge and groove are positioned on the center camber line of blade body, or convex ridge and groove are closer to a side of blade body.
Preferably, two sides conglobate crimping of side shape respectively inwards of blade body.
A kind of no-power air blower, including turbine main frame, described turbine main frame is formed around main shaft circumferential arrangement by the blade of multiple above-mentioned no-power air blowers.
Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:
In the present invention, the blade of no-power air blower includes blade body, blade body is highlighted along its camber line by Inside To Outside, forms convex ridge in the outside of blade body, forms groove in the inner side of blade body, so, blast is concentrated by the concave surface inside blade, and blast is decomposed by the convex surface of blade outboard to surrounding, thus the wind pressure expanding leave dual sides further is poor, improve the rotating speed of no-power air blower, thus extending the range of application of no-power air blower.

Fig. 4 is the left view of the blade of no-power air blower in Fig. 1.
Detailed description of the invention
As shown in Figures 1 to 4, Fig. 1 is the axonometric chart of the blade of a kind of no-power air blower that the present invention proposes, Fig. 2 is the front view of the blade of no-power air blower in Fig. 1, and Fig. 3 is the rearview of the blade of no-power air blower in Fig. 1, and Fig. 4 is the left view of the blade of no-power air blower in Fig. 1.
Referring to figs. 1 through Fig. 4, the blade of a kind of no-power air blower that the present invention proposes, including blade body 1, it is respectively arranged at two ends with connecting portion 2 in blade body 1,3, blade body 1 is highlighted along its camber line by Inside To Outside, forms convex ridge 11 in the outside of blade body 1, forms groove 12 in the inner side of blade body 1.
Blade body 1 is highlighted by Inside To Outside, concave surface is formed in the inner side of blade body 1, concave surface is formed in the inner side of blade body 1, in the course of the work, blast is concentrated by the concave surface inside blade, and blast is decomposed by the convex surface of blade outboard to surrounding, blade relative to the no concave-convex face of tradition no-power air blower, form male and fomale(M&F) in the both sides of blade body, the wind pressure expanding leave dual sides further is poor, improves the rotating speed of no-power air blower. When the wind speed of the only small and outside natural wind of indoor/outdoor temperature-difference is slower, the wind pressure by increasing leave dual sides is poor, and no-power air blower remains able to run up, thus extending the range of application of no-power air blower.
In a further embodiment, the height of convex ridge 11 and the degree of depth of groove 12 are gradually reduced from the middle part of blade body 1 to two ends, convex ridge and groove in blade body to the transition gradually of its two ends so that distinguished and admirable more smooth and easy.
In a further embodiment, convex ridge 11 and groove 12 are positioned on the center camber line of blade body 1, or, convex ridge 11 and groove 12 are closer to a side of blade body 1.
In a further embodiment, the conglobate crimping 21,22 of two sides side shape respectively inwards of blade body 1, the dual-side of blade body is formed crimping, it is possible to be greatly enhanced the flexural deformation of blade.
Based on the blade of above-mentioned no-power air blower, the invention allows for the no-power air blower applying above-mentioned blade, it includes turbine main frame, and described turbine main frame is formed around main shaft circumferential arrangement by the blade of no-power air blower many sections above-mentioned.
Based on the technique effect of the blade of above-mentioned no-power air blower, the no-power air blower applying this blade has above-mentioned beneficial effect equally.
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope that the invention discloses; it is equal to replacement according to technical scheme and inventive concept thereof or is changed, all should be encompassed within protection scope of the present invention.
