Vertical axis windmill is applied in the human sphere of life very early, and it is exactly vertical axis windmill that China utilizes the form of wind energy the earliest.But the invention of vertical axis aerogenerator then than trunnion axis a little later, just begins to occur up to the twenties in 20th century (Savonius formula wind wheel---nineteen twenty-four, Darrieus formula wind wheel---1931 years).Because people generally believe that the tip-speed ratio of vertical axis rotor can not be greater than 1, wind energy utilization is lower than horizontal axis wind-driven generator, thereby causes vertical axis aerogenerator to can not get for a long time paying attention to.
Along with improving constantly of development of science and technology and human knowledge's level, people recognize that gradually the tip-speed ratio of vertical axis rotor can not only be only applicable to resistance-type wind wheel (Savonius formula wind wheel) greater than 1, and the tip-speed ratio of lifting wind wheel (Darrieus formula wind wheel) even can reach 6, and its wind energy utilization also is not less than trunnion axis.In recent years, include the track of socio-economic development gradually in along with clean energy resource, utilize wind power generation to be admitted by the abundant country of most of wind resources, in the field that solves the efficient generating of wind energy, people need to provide in conjunction with reality the technical scheme of the higher vertical axis aerogenerator of tip-speed ratio in a hurry for this reason.How solving many group impellers in numerous technical schemes can the fixing and stable problem when quiet, moving state then be the problem that the insider painstakingly handles in advance, an important step of this problem be how the method for the keel frame that a kind of making can be used for installing impeller blade is provided and the keel frame made with this method supporting between the two with many group impellers.
Summary of the invention
Technical problem to be solved by this invention provides the preparation method that a kind of wind-driven generator is organized impeller keel frame more, fixing and the stable problem of quiet, the moving state when the keel frame made of method can solve many group impellers with the work of wind-driven generator coupling thus, and wind energy utilization and startup wind speed to improve blower fan.
For this reason, the technical scheme that the present invention solves described problem is: a kind of wind-driven generator is organized the preparation method of impeller keel frame more, comprise step, select anti-rust metal spare as the keel base material, adopt the step of forging and pressing, machining selected base material to be made the drag keel that has groove, afterwards, at an end boring fastener hole of keel, the other end of keel is processed into rectangle fixed block and boring installing hole thereon; To process and have the installing ring of lug more in addition is connected with installing hole on the fixed block.
Preferably, the groove of described keel, 2-20 centimetre of its groove depth, 0.5-3.7 centimetre of its groove width, thick 0.1-3 centimetre in its groove rib.
Preferably, the radian of described keel is 110 °-180 °.
Compared to existing technology, the good effect that the present invention has is, can make the keel frame that is applicable to many group impellers fully according to this method, and by installing ring and the fixed block that has lug every keel are connected as one, make on the blade integral that is installed in the keel groove apparent wind arbor shape in the shape of a spiral.Facts have proved, the preparation technology of this method possess skills the path simple and direct, be easy to make the stable and good characteristics of security of machine-shaping product and support body itself.

Fig. 3 is the preparation method's that relates to of this method a schematic flow sheet.
Among the figure: 1-installing ring, 2-keel fixed block, 3-keel, 4-blade face trip bolt, 5-keel groove (being the mounting groove on blade face).
The specific embodiment
In conjunction with Fig. 1 or Fig. 2 and Fig. 3, the invention provides the preparation method that a kind of wind-driven generator is organized impeller keel frame more, this method has provided concrete processing step from the selection to the making.For example, select anti-rust metal spare as the keel base material earlier, adopt the step of forging and pressing, machining selected base material to be made the drag keel that has groove then, afterwards, end at keel bores the fastener hole that can be used for the fastening page, and the other end with keel is processed into the rectangle fixed block and bores the installing hole that often can connect keel thereon again; To process and have the installing ring of lug at last in addition is connected with installing hole on the fixed block.Above manufacturing process seems simply, but relates to the blower fan of the different diameters of axle, and employed keel are different.Because be the shape of the two ribs of single groove, the blade face of different vane thicknesses there are different groove depths, groove width, requirement that cell wall is thick by its framework of keel of this method preparation; Say that in principle the groove that the diameter of axle is big, axostylus axostyle is grown keel that its impeller uses is inevitable dark, groove width, cell wall certainty are with big.For example, when doing the drive shaft of blower fan with 1.7 meters minor axises, be used for thick 0.48-0.49 centimetre of its blade edge of impeller of blower fan, the dark, wide, thick of its groove of keel that select for use this moment should be respectively 2 centimetres, 0.5 centimetre, 0.1 centimetre.The parameter of the keel groove that the present invention provides is that radix and the practice according to the supporting impeller of blower fan of different wind resources draws, therefore, actual selection is arranged, i.e. the groove of described keel, 2-20 centimetre of its groove depth, 0.5-3.7 centimetre of its groove width, thick 0.1-3 centimetre in its groove rib.
In addition, about the radian problem of keel because the present invention be how to improve the wind energy utilization of blower fan and start the demand of wind speed so research and development be the matching used keel manufacture craft of special impeller.Organize impeller as the spiral pivot of wind-driven generator then is the current optimal selection that is used for improving the wind energy utilization of blower fan more.This be because, the utilization of wind energy is to come surely with the size of the wind area of the fan blade of blower fan, the spiral pivot effect then is a kind of novel wind power transform mode.On structure, at first it is a kind of spiral pivot structure, and with respect to horizontal axial fan, it is radial flow type, and the same with existing vertical shaft type blower fan also all is to lay blade and directly utilize the thrust rotary work of wind along major axis.Moment of torsion is opposite and the single-wheel upright wind wheel is because the both sides blade of axle accepts wind-force simultaneously, cancels out each other, and output torque is little.So the keel that the present invention relates to must be tackled the requirement of many group impellers and be formulated the technical scheme of its preparation.Therefore the radian typical value of keel is set in 110 °-180 °; For example, when many groups impeller was turned form in the shape of a spiral, the keel radian then was set at 180 °.So, original vertical shaft moment output can be changed into the utilization on vertical spin blade face to the dependence of blade face blade hydrodynamics shape.Realize that this point can guarantee that spiral vane does not have any requirement to wind direction, come from any one direction can both wind-engaging for manage-style, and then promotes blower fan and rotate.
After finishing, can carry out the installation of blade by the keel of above-mentioned flow preparation.Blade face trip bolt 4 among Fig. 1,2 is that the edge, blade face that will insert keel groove 5 carries out fastening effect, and 2 of the keel fixed blocks of keel 3 other ends dock with installing ring 1, and many keel ring latch closures are connect.
Because keel framework of the present invention is at the design of many groups impeller, and the blade face apparent wind arbor of every group of impeller is the shape of turning in the shape of a spiral, so its optimal design of keel on carrying blade face also should be designed to semicircle.So design not only guaranteed whole many group impellers firmly and stable, also can make the blade face be from top to bottom Rotate 180 ° around the blower fan axle relatively simultaneously, and the wind-engaging effect is conspicuous during the rotation of spiral helicine 180 ° blade face.
