Description
The utility model relates to a kind of wind energy conversion system, particularly relates to a kind of upset power face that has, and is applicable to the wind energy conversion system of any wind direction and wind velocity.
There is following shortcoming in the transverse axis wind energy conversion system that uses at present:
1, only be applicable to the place use that wind direction, wind speed are fixing, use in the place that is unsuitable for wind direction, the fierce variation of wind speed, when wind speed surpasses 25m, need shut down wind sheltering, and benefit is low when medium wind-force, power supply instability;
2, speed governing and generator etc. all are arranged on top of tower, and this not only increases equipment investment, and installation, examination and maintenance are all inconvenient;
3, blade is streamlined, processing difficulties;
4, starting torque is little, the starting wind velocity height, and generating efficiency is lower, and cost of electricity-generating is higher.
The purpose of this utility model, be at above-mentioned with topic, provide a kind of simple in structure, starting torque is big, easy for installation, be applicable to the convertible wind energy conversion system that any wind direction and wind speed change.
The purpose of this utility model adopts following technical proposals to realize, that is:
Convertible wind energy conversion system comprises cabinet, support, bearing housing, vertical shaft, a plurality of transverse axis and a plurality of blade.Bearing housing is arranged on the support upper end, the vertical shaft lower end is arranged in the bearing housing, and power is imported into cabinet by the internal stent member, on vertical shaft, alternately vertically be fixed with 2 horizontal row axle sleeves respectively, and 2 horizontal row axle sleeves are orthogonal, put a spacing edge-cut at each transverse axis, and a plurality of transverse axis are supported by two horizontal row axle sleeves respectively, be fixed with stop screw on transverse axis, stop screw can slide along spacing edge-cut.At the two ends of blade, be fixed with 2 sleeve-boards respectively along the position of center line of blade, a spacing edge-cut is arranged on each sleeve-board.In the both sides of transverse axis a blade is installed respectively, the plane of these two blades is orthogonal.The concrete installation method of each blade is: transverse axis passes 2 sleeve-boards that are fixed on the blade.The upper end that it is characterized in that each blade is provided with a upset power face, this upset power face and blade are an overall structure (dynamically non-equilibrium to realize), be positioned on the transverse axis at blade position at each, be set with 2 springs, one end of 2 springs is separately fixed on the transverse axis, its the other end is separately fixed on the blade, make blade turn over several angle again along the winding direction of spring, make the turning torque that " upset power face " produces under the moment of torsion that is added on the spring and the rated wind speed consistent, then fix, do not make blade counterrotating under spring action with stop screw.Owing to have spacing edge-cut on the sleeve-board, thus stop screw not restraining spring rotate along the winding direction of spring.
When the utility model is subjected to positive blast, blade will change to the rollover that " upset power face " arranged, and drive transverse axis simultaneously and rotate.If natural wind speed is lower than rated wind speed, when transverse axis forwards the blade face to when perpendicular to the ground, under the effect of the stop screw of transverse axis cover, transverse axis no longer rotates.Under the effect of positive blast, blade just provides a moment of rotation for vertical shaft thus.At this moment, transverse axis, blade rotate around vertical shaft simultaneously.After transverse axis turns over the position parallel with wind speed, blade will be subjected to increasing negative blast.Because the existence of " upset power face ", blade will drive the X opposite direction and rotate, the stop screw of this moment allows transverse axis to rotate 90 degree in the opposite direction, makes the blade face parallel to the ground, has reduced the effect of negative blast to it; Meanwhile, the blade of the other end of transverse axis just with the ground quadrature, repeat said process at this moment again.As shown in the figure, transverse axis divides two row of arranging, and is mutually orthogonal, and simultaneously perpendicular with vertical shaft.The alternating action of the many a plurality of blades of transverse axis will provide powerful torque for vertical shaft.
After the wind speed in the external world surpasses rated wind speed, the same the same under the effect of the stop screw that transverse axis overlaps, transverse axis will no longer rotate.But the moment of rotation that provide this moment " upset power face " is greater than the torsional moment that is preset in the spring, and therefore, moment of rotation will promote blade and rotate around transverse axis, will reach balance in a certain position turning torque and torsional moment.Because blade has turned over certain angle around transverse axis, then reduced the cross section that facings the wind of blade, the positive blast that makes whole blade be subjected to reduces, thereby has reduced exerting oneself of whole device, has protected the safety of blade and the safety of whole device.Under the situation of meeting especially big wind speed and powerful fitful wind, this structure highly sensitive in any electric control equipment, not interrupt run.
This device starting wind velocity is low, and the highest operating air velocity is not limit, and rated wind speed is determined by the wind regime of installing zone in the structural safety scope.When the mean wind velocity of installing zone hangs down, can increase the cross section that facings the wind, determine rated wind speed by increasing transverse axis by adjusting the spring predetermined torque.So not only having guaranteed that device has when low wind speed higher exert oneself but also has guaranteed not make under high wind speed the device be damaged.
The utlity model has following advantage:
1, without the wind direction measuring and controlling.Be applicable to the constant and high speed shift zone of any wind direction;
2, Zhuan Zhi speed governing and generator etc. all place ground, are convenient to installation check and safeguard;
3, blade is plate, is convenient to selection, is easy to processing and maintenance;
4, can exert oneself by increasing the windward side raising easily, the district also can obtain good economic benefit in medium wind speed and wind;
5, this device is safe and reliable.Under any high wind speed, but all work of highly effective and safe, need not shut down wind sheltering, and can be controlled at output power in the safety range;
6, starting torque is big, and starting wind velocity is lower than any transverse axis wind energy conversion system;
7, processing charges is low.The 50-60% that has only import transverse axis wind energy conversion system, generating efficiency improves 30-50%.
