Abstract
The invention discloses a volute tower-like vertical-axis wind turbine and aims to provide a large wind turbine which is durable, higher in power and easy to construct. The volute tower-like vertical-axis wind turbine comprises a tower, a vertical-axial rotor and blades; the tower is in a volute tower structure; the vertical-axis rotor and the blades are mounted in the center of the tower and protected by the tower. According to the design scheme, a wind turbine with highest power in the world can be built.
Description
Technical field
The present invention relates to a kind of wind generating unit, more particularly it relates to a kind of device wind energy transformation being become mechanical energy.
Background technique
Wind energy is clean energy resource, and could not make full use of is exactly serious waste, utilizes wind-power electricity generation to be reduce one of air-polluting effective measures on a large scale.Large-scale horizontal axis wind turbine complex process, involves great expense, fragile, once damage maintenance difficult.Vertical-axis wind turbine compares horizontal axis wind turbine does not need adjusted device, structure is relatively simple, but vertical-axis wind turbine is along with the increase of height, stability is poorer, the large-scale vertical wind turbine compared with horizontal axis wind turbine cannot be built, and these rotor blades being no matter horizontal axis and vertical-axis wind turbine are all exposed in physical environment, are easily damaged by factors such as Exposure to Sunlight, sleet, hail, turbulent flows.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of by rotor and blades installation a kind of vertical axis rotor machine in volute tower type pylon.
The tower vertical-axis wind turbine of volute of the present invention comprises pylon and rotor two-part, and described pylon is volute tower structure; Described rotor is vertical shaft, and rotor blade is arc tabular, or is combined into S shape double-leaf, or three-vane, or is other forms such as straight-plate-type; Rotor main shaft rigid bearing is located at tower top and bottom, or increases in pylon inside; Described rotors normal is arranged on volute tower type pylon inside center.
Owing to adopting technique scheme, wind turbine provided by the invention has such beneficial effect, the rotation of vertical axis rotor machine rotor is because the power suffered by work done face is greater than the power suffered by resistance area, just can rotate, but the wind energy acting on resistance area can cut down work done face institute work, present this volute design changes airflow direction, wind energy is substantially all acted on work done face, improves the power of vertical-axis wind turbine; Pylon adds the cut-off wind area of rotor in the horizontal direction, constantly can increase vertical height again, can build higher pylon, obtain the cut-off wind area wanting to reach, even can build up the wind turbine of power the biggest in the world in the mode that solid construction unit upwards superposes; Its miniaturization can be used for family; Pylon can easily be built with frame structure with reinforced concrete, and circular symmetric volute tower structure is firm, and wind resistance power is strong, divisible turbulent flow, and can build various ways ratio pylon as required; Enclose this kind of structure at top, internal rotor blades can be protected from infringements such as Exposure to Sunlight, sleet, hails, also reduce the blade of rotation to electromagnetic interference; Rotor rigid bearing is arranged on tower top and bottom, or increases in pylon inside, and stress equalization is rational in infrastructure not fragile; Fan rotor is arc tabular or is combined into S shape double-leaf, or three-vane, blade is connected with the rotor main shaft clutch that bearing or slide type control with speed probe, and when wind speed exceedes the work wind speed range of wind turbine, or generator gets rid of load suddenly, wind turbine is caused to exceed the speed limit, when wind turbine may be caused to damage, speed probe makes clutch separation, and blade gains freedom on main shaft, Automatic-searching wind-engaging minimum position and form, wind turbine also stall hedging thereupon; Tower top can build beacon, signal transmitting tower, lookout lookout terrace etc.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the invention will be further described:
In Fig. 1 .2.3., vertical collection brattice 1 around arrangement with volute, is combined into solid with horizontal floor layer 2 and builds unit, build tower type pylon in the mode upwards superposed.
In Fig. 4 .5.6., two arc tabular blades may be combined with into S shape blade, add disc-shaped flywheel up and down, can strengthen blade strength and energy storage, can easily be started with the superposition of Fig. 6 form, rotate rotor and the blade of more steadily enough height.
In Fig. 7 .8., this volute pylon can make variform and ratio as required.
In Fig. 9 .11.10.12., for blade when pylon and rotor blade normal operation and hedging changes the situation after form.
Claims (2)
1. wind turbine comprises pylon and vertical axis rotor rotor and a blade, and it is characterized in that pylon is volute tower structure, described vertical shaft rotor and blades installation are in pylon inside center.
2. its rotor main shaft rigid bearing of vertical-axis wind turbine according to claim 1 is arranged on tower top and bottom, or increases in pylon inside.
