Abstract

The utility model relates to a fan, in particular to a shutter type omnidirectional fan, which comprises a rotary shaft and fan blades, and is characterized in that a wind tube (1), which is shaped like a container, is arranged outside the rotary shaft (4) and the fan blades (5), the wall of the wind tube (1) consists of a plurality of wind deflectors (2) and a frame (3), each wind deflector (2) makes an included angle with a straight line passing through the tube center, an wind gap (6) is arranged between each two wind deflectors (2), and thereby a shutter type structure is formed. Since the shutter type wind tube is adopted, most of the wind in any direction can be guided by the wind deflectors to form effective wind power opposite to the concave surfaces of the fan blades, consequently, the utility model resolves the problem that the wind powers at both sides of the rotary shaft of the radial flow type fan counteract each other, and thereby the utilization rate of wind power is notably increased. Moreover, the utility model has the advantages of simple structure, low fabrication cost, reliable performance and the like, and the market prospect of the utility model is promising.

Description

Blinds universal wind-power machine

Affiliated technical field

The utility model relates to a kind of wind energy conversion system, promptly a kind of blinds universal wind-power machine.

Background technique

Present wind energy conversion system is divided into two kinds of axial flow and radial-flow types, and the radial fan blowing area is more much bigger than axial fan, because to exist the stressed torque direction in rotating shaft both sides opposite, and the problem of cancelling out each other, thereby be difficult to promote.Axial fan no matter or radial fan all need to install an empennage, are used for changing direction, so that wind wheel remains the state that facings the wind., empennage not only has certain weight, and hangs in height, and damages easily.In addition, the wind wheel under empennage drives also needs the frequent transitions direction, has increased the complexity of structure and the incidence rate of fault.

Summary of the invention

The purpose of this utility model provides a kind of wind-force that utilizes all directions, and wind energy conversion system simple in structure, cheap, working stability.

Above-mentioned purpose is realized by following technological scheme: develop a kind of blinds universal wind-power machine, comprise rotating shaft and fan page or leaf, be characterized in: there is an air duct outside at rotating shaft and fan page or leaf, it is container-like that air duct is, the barrel of air duct is made of many wind deflectors and framework, each wind deflector is angle with straight line by the tube heart, be ventilation gap between the wind deflector, formation louvre type structure.

Said air duct is cylindrical.

Said air duct is palace lantern shape.

Said air duct is prismatic.

The rotating shaft of said wind energy conversion system is a vertical shaft, fan page or leaf be distributed on vertical shaft around, the section bending of fan page or leaf is curved, its concave surface is relative with the direction of the wind deflector plate face of vicinity one side.

The beneficial effects of the utility model are: owing to adopted the louvered air duct, the wind of direction whatsoever, its major part of determining all is the effective wind relative with the fan concave surface by the wind deflector guiding, thereby has solved the problem that radial-flow type wind energy conversion system two cross forces are cancelled out each other, and the wind power utilization rate significantly improves.And have advantages such as simple in structure, cheap, reliable performance, its market prospects are very considerable.

Among the figure as seen: air duct 1, wind deflector 2, framework 3, rotating shaft 4, fan page or leaf 5, gap 6, generator 7.

Embodiment

First kind of embodiment: by the general structure of Fig. 1,2 visible this facility, its air duct 1 shape such as cylinder support uniform many oblique wind deflectors 2 all around by framework 3.As shown in Figure 2, the said oblique plate face of wind deflector 2 that is meant here intersects with the radius of crossing the center of circle and the formation angle, constitutes the barrel of similar louvre type.The center of circle here is the axis that air duct 1 and rotating shaft 4 have.It between the wind deflector 2 gap 6 that can ventilate.By Fig. 3,4 as seen, the rotating shaft 4 of a setting is equipped with in air duct 1 the inside, and uniform on every side three fan pages or leaves 5 are a kind of typical radial-flow type wind energy conversion systems.The shape of fan page or leaf 5 has multiple, and what exemplify here is that the page is crooked and present the fan page or leaf 5 of concave surface and convex surface.

Fig. 5 attempts to illustrate the working principle of this facility: arrow is represented the wind comes from from all directions.As seen, not taking turns is that what direction be the wind comes from, all can enter in the tube along the gap 6 of wind deflector 2, and relative with the concave surface of fan page or leaf 5.The air-flow of loss is considerably less, and this thus blower fan can well utilize wind-force, has removed the stressed phenomenon of cancelling out each other in radial fan both sides.

Second kind of embodiment: as shown in Figure 6, the shape of air duct 1 is the palace lantern shape, and generator 7 is housed below, can utilize wind-power electricity generation.The form of this wind energy conversion system of this example explanation is diversified, not only appearance is different, as be cylindric, prism-shaped, irregularly shaped etc., and purposes is also inequality, and what have can drive generator 7, and what have can drive water elevator, what have can drive beater, or the like, as long as the peripheral structure with louvre type of blower fan all belongs to the technological scheme that is equal to.
