Abstract

The utility model relates to a universal fan impeller with a compact structure, which is capable of realizing a wind power starting function which is irrelevant with a wind direction and very high wind power efficiency, and simultaneously, is capable of greatly reducing the operating maintenance difficulty and the working capacity by the simple blade structure of the universal fan impeller. The universal fan impeller comprises a plurality of fan blades fixedly connected onto a rotor-shaft structure; each fan blade is divided into three sections: an upper wind guide blade section, a main windward turbofan blade section and a lower wind guide blade section, thus, a curve blade body with a concave vortex surface and a convex vortex surface is formed. No matter what the wind direction is, one side of the axis of the universal fan impeller is a high-wind resistance side always, and the other side of the universal fan impeller is a low-wind resistance side always, thereby, rotary power is caused.

Description

A kind of universal fan blade
Technical field
The utility model 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 utility model provides a kind of universal fan blade of compact structure, and 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 utility model provides a kind of universal fan blade of compact structure, and 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.The universal fan blade overall profile is a near cylindrical, approximate rectangular according to radially being one, symmetrical up and down, integral body is made of the some reinforced glass plastic materials fan leafs that are cemented on rotor-axle construction, 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, and forms the curved surface lamellar body that has indent vortex sheet and the grand face of evagination.
The technological scheme that its technical problem that solves the utility model adopts is: universal fan blade mainly is made of some 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 indent vortex sheet of high windage and the grand face of evagination of low windage, form the two sides of spoon of blade lamellar body.Each blade is cemented on the post side of rotor-axle construction by the indent vortex sheet in the same way, and per two blade outer side are equated along the line institute angle to the inner side edge edge, radially makes 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 always high windage side of its axis one side, the always low windage side of opposite side, thus cause rotating power.
The beneficial effects of the utility model are: realized and irrelevant wind engine function of wind direction and very high wind-force efficient, and compact overall structure simultaneously, blade structure is succinct, and operation maintenance difficulty and workload are reduced greatly, is easy to produce, installation.
