The fan blade wheel consists of a plurality of flexible fan blades which are fixedly connected to a rotor-shaft structure, wherein each flexible fan blade consists of an upper guide fan blade section, a main windward vortex fan blade section and a lower guide fan blade section to form a flexible curved face body with a concave vortex surface and a convex surface; the fan blades are in the same tangential direction of concave vortex surface and are fixedly connected to the post side face of the rotor-shaft structure; included angles between connecting lines of the outer side edges and the inner side edges of every two fan blades in the axial direction are the same as each other; and the connecting line between the upper top point and the lower top point of each fan blade is parallel with an axial lead in the radial direction.

Description

Flexible universal fan blade
Technical field
The present invention relates to a kind of wind motor fan blade.
Background technique
At present, the fan blade of nearly all wind-driven generator or the fan blade of other pneumatic power all are unidirectional drive, its wind-force efficient will lean on continuous adjustment to facing the wind or the guaranteeing of downwind, thereby makes wind motor system architecture complexity, so that adds the wind direction following control system in addition.Like this, not only cause cost to improve, but also operating cost is improved, working efficiency reduces.Particularly the high-power system wind motor even if be provided with good wind direction following control system, also is difficult to the highly sensitive servo-actuated of accomplishing that quick, frequent wind direction changes.Therefore, researching and developing the irrelevant wind motor of a kind of wind direction, is problem demanding prompt solution.Existing universal fan blade is the unidirectional upright turbofan structure of a kind of frame type, can realize the wind engine function that wind direction is irrelevant, but its wind-force efficient is very low.The universal fan blade of research and development is structures that a kind of Da Ye fan has little flap fan recently, though can realize wind engine function that wind direction is irrelevant and very high wind-force efficient, but its complicated blade structure will make operation maintenance difficulty and workload strengthen, and also cause very high operation noise and loss simultaneously.The invention provides a kind of flexible universal fan blade of compact structure, it can realize wind engine function that wind direction is irrelevant and very high wind-force efficient, and the while can make operation maintenance difficulty and workload reduce greatly with its succinct blade structure.
Summary of the invention
The invention provides a kind of flexible universal fan blade of compact structure, it can realize wind engine function that wind direction is irrelevant and very high wind-force efficient, and the while reduces operation maintenance difficulty and workload with its succinct blade structure greatly.It is to be made of the some flexible fan leaf that is cemented on rotor-axle construction, and each fan flexible blade is divided into wind-guiding leaf section, main turbofan leaf section and three sections of following wind-guiding leaf section of facining the wind, and forms the flexible curved surface lamellar body that has indent vortex sheet and the grand face of evagination.
The technical solution adopted for the present invention to solve the technical problems is: universal fan blade mainly is made of some flexible fan leafs, each fan leaf is divided into wind-guiding leaf section, main turbofan leaf section and three sections of following wind-guiding leaf section of facining the wind, with the high windage indent vortex sheet that facings the wind and the leeward grand face of low windage evagination, constitute the two sides of spoon of blade lamellar body.Each blade by the indent vortex sheet tangentially in the same way, be cemented on the post side of rotor-axle construction, and per two blade outer side are equated along the line institute angle to the inner side edge edge, radially make on each blade the summit to the line and the axis parallel on summit down.With this universal fan blade that constitutes, regardless of wind direction, the high windage side of recessed vortex sheet that its axis one side always facing the wind to be launched, the opposite side low windage side of protruding grand face of polycondensation of always facining the wind, thus cause rotating power.
The invention has the beneficial effects as follows: but with the flexible blade of polycondensation and expansion, the facing the wind wind-force effect of the low windage side that polycondensation forms of high windage side that facing the wind to launch forms by recessed vortex sheet and protruding grand face, realized and irrelevant wind engine function of wind direction and very high wind-force efficient, the while compact overall structure, blade structure is succinct, operation maintenance difficulty and workload are reduced greatly, be easy to produce, install.
