Abstract
The invention aims to provide an extensible vertical axis wind power generator which comprises a power generator, a control motor, a nut, a main axis as well as a brake device, a drive screw rod and a blade, wherein the brake device, the drive screw rod and the blade are installed on the main axis; the drive screw rod is connected with the control motor; the nut is installed on the drive screw rod; the blade is installed on the main axis through a spoke and is connected with the nut through a support rib plate; and when the nut moves up and down on the drive screw rod, the blade unfolds and folds through the spoke and the support rib plate. According to the invention, the problem that the sweep area of the existing fan blade can not be regulated is overcome, through regulating the sweep area of the blade, the adaptive wind speed range of the vertical axis wind power generator is widened, and the power generation quantity of the vertical axis wind power generator is increased.
Description
Technical field
What the present invention relates to is a kind of wind generating unit of power field.
Background technique
Vertical axis windmill is applied in the human life very early, and it is a kind of form that Chinese earliest period is utilized wind energy.But the appearance of vertical axis aerogenerator will be a little later than the appearance of horizontal axis wind-driven generator.Because people generally believe that the wind energy utilization of vertical shaft is lower than horizontal axis wind-driven generator, thereby cause vertical axis aerogenerator to can not get for a long time people's attention.Along with the development of science and technology and improving constantly of human knowledge's level, increasing organization and the individual vertical axis aerogenerator that begins one's study, and obtained very large development.The vane airfoil profile of existing vertical axis aerogenerator is symmetrical, and the axis of blade is parallel with the axis of gyration center, and these blades generally are fixed on the circumference that rotates around the spindle, and blade is connected to connect by spoke with main shaft.When the blade that these have certain aerofoil profile is crossed in wind, just produced the moment of rotating around vertical shaft, whole wind wheel is rotated.The swept area of existing vane of vertical shaft wind-driven generator is uncontrollable, is difficult to be adapted to wider wind speed range.
Summary of the invention
The object of the present invention is to provide the type of extension vertical axis aerogenerator that freely stretches by expansion and the gathering mechanism realization of increase blade.
The object of the present invention is achieved like this:
Type of extension vertical axis aerogenerator of the present invention, it is characterized in that: comprise generator, control motor, nut, main shaft and be installed in braking device, turn-screw, blade on the main shaft, turn-screw connects the control motor, nut is installed on the turn-screw, blade pass crosses that spoke is installed on the main shaft and by the bearing rib attaching nut, when nut moved up and down at turn-screw, blade pass crosses spoke and bearing rib launches and gathering.
The present invention can also comprise:
1, described turn-screw has two, and two turn-screws are arranged symmetrically with around main shaft, couples together with the gear of toothed belt with two turn-screw ends, and one of them turn-screw connects the control motor.
2: described turn-screw has four, and four turn-screws are arranged symmetrically with around main shaft, couples together with the gear of toothed belt with four turn-screw ends, and one of them turn-screw connects the control motor.
3, also comprise two bearings, clutch shaft bearing is fixed on the joint of main shaft upper driving leading screw and main shaft, and the second bearing is fixed on the nut and with nut and does up and down straight line motion.
4, described blade is at least three.
Advantage of the present invention is: the present invention has overcome the nonadjustable problem of existing fan blade sweeping area, and by adjusting the sweeping area of blade, the wind speed range that described vertical axis aerogenerator is adapted to is widened, and increases the generated energy of vertical axis aerogenerator.

Fig. 2 is the plan view of mounted blade of the present invention;
Fig. 3 is the schematic representation of vanes retract of the present invention;
Fig. 4 be A-A of the present invention to sectional view.
Embodiment
For example the present invention is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～4, the type of extension vertical axis aerogenerator is comprised of critical pieces such as generator 10, braking device 9, main shaft 6, blade 1 and spokes 2, the blade 1 that its characteristics are to have certain symmetrical airfoil and main shaft 6 are parallel and around its even distribution, spoke 2, main shaft 6 and blade 1 adopt chain connection.
When ambient wind velocity is lower than the limiting value of rated wind speed, make control motor 8 drive turn-screw 5 and continue forward rotation, nut 4 continues upwards to do straight line motion.By increasing the swept area of described type of extension vane of vertical shaft wind-driven generator 1, realize that impeller catches the maximum of wind energy.
When ambient wind velocity is higher than the limiting value of rated wind speed, make control motor 8 drive turn-screw 5 backward rotation, nut 4 is done straight line motion downwards.By reducing the swept area of described type of extension vane of vertical shaft wind-driven generator 1, with power stability near rated power.In the working procedure of whole wind-driven generator, control motor 8 can be controlled rotating nut 4 and rest on arbitrary position on the main shaft 6.
Increase by two bearings in two positions of I, II, the bearing I inner ring is fixed on the main shaft 6, and the inner ring of bearing I I is fixed on the nut 4, does straight line motion up and down with nut 4, and particular location is seen Fig. 1.These two bearings separate main drive gear with control mechanism.Namely when blade 1 rotated, control motor 8 can be controlled stretching, extension and the gathering of blade 1, does not rotate and do not need to stop blade 1.Control mechanism has two covers to pass to leading screw 5 and nut 4, connects the gear 11 of two turn-screw 5 ends with toothed belt 12, control mechanism can guarantee in this way two turn-screws 5 in the same way, synchronized, synchronous rotation, see Fig. 4.
In force, generator is arranged on below the main shaft 6 of type of extension vertical axis aerogenerator.By coupling it is connected with main shaft 6.In order to reach best aerodynamics effect, low power type of extension vertical axis aerogenerator can dwindle the associated components sizes such as spoke 2, bearing rib 3, blade 1 accordingly, but for powerful type of extension vertical axis aerogenerator, can strengthen the relevant part dimension such as corresponding spoke 2, bearing rib 3 and blade 1, the quantity of blade 1 also needs to increase simultaneously.
