Description
It is the device of mechanical energy that the utility model relates to wind energy transformation, and the rotation that particularly utilizes fan blade is with the device of wind energy transformation for mechanical energy.
Existing wind energy power machine mostly adopts by afterbody direction-regulator or other modes and regulates direction, makes oblique fan blade blade face in the face of wind direction, under the promotion of wind-force, fan blade produces rotation, is the process of mechanical energy thereby finish wind energy transformation.Because it is simple in structure, cost is lower, so wind energy power machine in the world adopts this structural type more.But because the size and the number of the fan blade of existing wind energy power machine are limited, and fan blade is oblique structure, and the sense of rotation of fan blade is vertical substantially with wind direction, thereby utilization ratio of wind energy is lower, and especially the power that is produced is less.
The purpose of this utility model is: a kind of wind energy power machine is provided, and the fan blade sense of rotation of this machine is substantially parallel with wind direction, and can take to increase the method for fan blade, increase overall lifting surface area, thereby, can improve utilization ratio of wind energy, especially can produce bigger power.
The purpose of this utility model is achieved in that on horizontal plane, the base of fixing belt rigid bearing and support body bearing, and the fixed support of band rigid bearing.One axis is penetrated the rigid bearing on the base and the endoporus of the rigid bearing on the fixed support, and the lower end is on the support body bearing, and vertically stable the placement can be rotated axis around self axle center.Axis is provided with sleeve pipe, is provided with the cross bar that is the level of state on sleeve pipe, and the appropriate location at cross bar is connected with fan blade, and the blade face axle of fan blade is fixed on the cross bar, and all blade faces of fan blade are in cross bar one side, is a vertical plane when blade face subtended angle is 180 °.The one side on blade face is connected on the axle of blade face by the axle sleeve activity, but the blade face opening and closing, when meet, when leeward, the blade face present open, closed two states.On the axle of blade face, be fixed with horizon bar vertical with the blade face axle and that be the level of state, on horizon bar or blade face, be provided with the restriction post, the subtended angle scope on blade face can be controlled in the proper range.
When the blade face facingd the wind, wind-force opened the blade face, formed bigger stress surface, thereby produced bigger power and braking torque; When the blade face was leeward, wind-force made the blade face closure, formed less stress surface, thereby produced less resistance and resisting moment; Under the effect of the difference of braking torque and resisting moment, fan blade is blown and is driven the axis rotation, is provided with motive power wheel on axis, and when axis rotated, motive power wheel rotated thereupon, thereby by band, wheel or gearbox kinetic energy was sent out.
Between horizon bar of the present utility model and the blade face, can be even with strut, an end of strut is connected in point of contact by the axle activity, move the other end contact that can connect, on horizon bar or blade face, be provided with the restriction post, can limit the moving range of strut mobile terminal, and then the subtended angle scope on control blade face.
The blade face of fan blade of the present utility model, its shape can be a kind of of plane or curved surface; The formation on blade face can be the whole face of single face, two-sided, multiaspect or umbrella; The material on blade face can be selected hard materials such as steel, wood for use, under situation about being fit to, also can select soft materials such as canvas, oilcloth for use.
Because fan blade of the present utility model is met when leeward when the blade face, is the folding two states, thereby the power lifting surface area is much larger than the resistance lifting surface area, and the fan blade sense of rotation is substantially parallel with wind direction in addition, thereby wind energy utilization is higher, and the power that is produced is bigger.Another advantage of the present utility model is also to adopt the many groups of tower structure design fan blade on axis.Of the present utility model being also advantageous in that, fan blade is stressed can be consistent with wind direction at any time voluntarily, need not increase the wind direction regulating equipment, or takes externalist methodology to regulate.
