Technical field

The utility model relates to a kind of wind-driven generator, and especially a kind of louvre blade transverse horizontally rotates 360 ° of wind-engaging wind-driven generators without tower.

Background technique

Existing wind-driven generator, need very high tower bridge that generator and wind page are given rise to the very high wind-force that obtains in the air, because wind page hinge is long and be vertically to rotate, so the height of tower bridge must surpass the length of wind page hinge, owing to also will carrying the weight of generator, so the manufacture of tower bridge will spend a lot of materials, and the excavation Embedment and installation on its basis also needs to consume a lot of manpower and materials, and the generator of tower top and wind page also will pursue the variation of wind direction and rotate, so existing method is still perfect not.

Summary of the invention

The purpose of this utility model be to provide a kind of simple in structure, cost is low, be easy to install, safe and reliable louvre blade transverse horizontally rotates 360 ° of wind-engaging wind-driven generators without tower, to overcome the deficiencies in the prior art.

The utility model is achieved in that a kind of louvre blade transverse of the present utility model horizontally rotates 360 ° of wind-engaging wind-driven generators without tower, wherein, it be provided with one perpendicular to ground can 360 ° of rotations rotating shaft, this rotating shaft is located on a support by bearing, and the lower end of rotating shaft is passed support and by coupling, connected speed regulating mechanism and the generator that is placed on ground; In rotating shaft, be symmetrically welded and be provided with at least two wind pages, this wind page is divided into by the welding of the pipe of vertical and horizontal that at least one row's who arranges in length and breadth rectangular frame forms, pipe horizontal on each rectangular frame is as the fan blade bobbin, the rectangular air blade of hinged a slice on the fan blade bobbin of each rectangular frame, this air blade can rotate around the fan blade bobbin.The framework that overworks air blade just forms a complete wind page.

Further, aforesaid air blade top is provided with semicircle or circular axle sleeve and by this axle sleeve, its hanging sleeve is formed on the fan blade bobbin hingedly, puts up the hinged place at lower row's air blade and fan blade bobbin below air blade.

Further, in rotating shaft, be symmetrically welded and be provided with 2～8 wind pages.

Further, aforesaid air blade is by the rectangle structure light, that thin material is made.

Further, aforesaid light, thin material is plastic sheet or aluminum alloy sheet.

In addition, the rectangular frame be divided in the width of aforesaid air blade and wind page equates, highly is greater than the height of this rectangular frame.

Simultaneously, the height of support is greater than 1 meter, namely will be over the interlayer thickness of wind-force in aerodynamics on ground.

Owing to having adopted technique scheme, during the utility model work, no matter wind in any direction blows, when the wind-engaging of the front of air blade, air blade is because own wt naturally droops, form a complete wind-receiving face and obtain wind-force, the promotion rotating shaft is rotated, when the wind page is obtaining the wind-force acting windward to 0～180 ° after, while forwarding the backhaul of 180～360 ° to, the back side wind-engaging of air blade, air blade is opened by wind, around air blade, axially above rotate and form the mouth that leaks out, thereby greatly reduced steering resistance, the rotating shaft of rotation drives the generator generating by speed regulating mechanism.The utility model compared with prior art, that the utility model not only has advantages of is simple in structure, it is novel to make, fabricating cost is low, but also have safe and reliable, economical and practical, be easy to install, save the advantages such as raw material, environmental protection, easy, the suitable wind energy turbine set of maintenance, city roof resident family, street top of street lamp post and rural area unshared housing install and use.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

An embodiment of the present utility model: see Fig. 1, Fig. 1 has showed the plan view of device of the present utility model, in figure, air blade 4 back sides of left-hand component are hiked up around fan blade bobbin 3 and rotate by wind, and right-hand component air blade 4 front wind-engagings naturally droop the wind-receiving face of formation and obtain Wind power propelling rotating shaft 1 and rotate.See Fig. 2, Fig. 2 has showed the side elevation view of device of the present utility model, and this device is provided with a rotating shaft 1, and welding wind page 2, be provided with altogether in this embodiment 6 phase countershafts 1 and be the wind page 2 be arranged symmetrically with in twos in rotating shaft 1.Rotating shaft 1 is arranged on support 5 by bearing perpendicular to ground, and the lower end of rotating shaft 1 is passed support 5 and by coupling, connected speed regulating mechanism 6 and the generator 7 that is placed on ground, just can drive generator 7 generatings by speed regulating mechanism 6 when rotating shaft 1 is rotated.In symmetrical in twos wind page 2, when the sagging formation wind-receiving face of air blade 4 front face wind-engaging on one of them wind page 2, obtain wind-force (right-hand component in Fig. 2), air blade 4 back side wind-engagings on corresponding another wind page 2 are blown horizontal hiking up and are formed left-hand component in mouthful 8(Fig. 2 that leaks out), reduce blowing area, thereby reduce steering resistance.

Continue to see Fig. 2, as we can see from the figure, the framework of wind page 2 is divided into by the pipe welding of vertical and horizontal a plurality of rectangular frame of arranging in length and breadth, pipe horizontal on rectangular frame is as fan blade bobbin 3, each rectangular frame is hung a slice air blade 4, air blade 4 is rectangular, width equates with the width of this rectangular frame, highly be slightly larger than the height of this rectangular frame, the top of air blade 4 is made into semicircular axle sleeve hanging sleeve and on fan blade bobbin 3, forms hinged (in conjunction with the schematic construction of showing in Fig. 3 and Fig. 4), the hinged place of below another air blade 4 and fan blade bobbin 3 is put up in bottom, the framework that overworks air blade 4 forms a complete wind page 2.

Air blade 4 is done rectangularity by light, thin material (as plastic sheet, aluminum alloy sheet etc.).In this embodiment, in rotating shaft 1, weld altogether 6 wind pages 2, uniform ringwise centered by rotating shaft 1,60 °, each wind page 2 interval.

The height of support 5 of the present utility model is greater than 1 meter, be over the interlayer thickness of wind-force in aerodynamics on ground.Speed regulating mechanism 6 and generator 7 are existing product in addition.

During the utility model work, no matter wind in any direction blows, (see figure 3) when the wind-engaging of the front of air blade 4, air blade 4 is because the weight of self naturally droops, due to the height of air blade 4, be slightly larger than simultaneously the height of rectangular frame, the bottom of air blade 4 is subject to stopping of rectangular frame can't be by horizontal of wind, thereby form a complete wind-receiving face and obtain wind-force, promoting rotating shaft 1 rotates, when wind page 2 is obtaining the wind-force acting windward to 0～180 ° after, (see figure 4) while forwarding the revolution stroke of 180 °～360 ° to, the back side wind-engaging of air blade 4, air blade 4 is opened by wind, around fan blade bobbin 3, rotate and form the mouth 8 that leaks out, thereby greatly reduced steering resistance, the rotating shaft 1 of rotation drives generator 7 generatings by speed regulating mechanism 6.

Certainly, be more than concrete exemplary applications of the present utility model, the utility model also has other mode of execution, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, within all dropping on the desired protection domain of the utility model.
