Background technique:

Wind motor, in modern energy development field, has critical role, along with scientific technological advance, the pattern of wind motor also day by day increases, in order to improve energy utilization ratio, U. S. Patent 4486148 has proposed the improvement project of collector plate structure, this collector plate can form the windward side of favourable wind motor rotor rotary work, stop the wind face that those are unfavorable for the rotor rotary work simultaneously, but this kind structure, the control of airflow capacity is subjected to the restriction of plate structure, difficulty reaches air-flow and enters rotor blade with the optimum state, at the problems referred to above, the Chinese patent name is called " band concentrator fluid energy conversion equipment and using method ", the patent No. is ZL94114034.2, another improvement project has been proposed, this scheme is by rotor, concentrator, frame, last rail frame, following rail frame, wind rudder and coupling are formed, its concentrator includes the conflux side plate, the conflux guide plate, fixed plate and framework, form one from outside to inside contracted channel, when fluid during through this contracted channel, flow velocity increases, can improve wind energy utilization, and its rotor inoperative half cycle is not impacted by High Speed Flow Field, energy loss reduces, its conflux side plate and conflux guide plate are provided with the control lashing, rate of flow of fluid in the may command contracted channel, and the rate of flow of fluid that can guarantee to enter the working rotor half cycle is more stable, thereby the stable preferable states that remains on of the output that makes wind motor, but at its whole board-like side plate and guide plate, sensitivity adjustment to the windward side is relatively poor, still can not give full play to the function of energy collector, and the lashing mechanism of its corresponding two groups of control side plates and guide plate, its structure more complicated, assembling, safeguard all inconvenient, the rotor of this scheme, concentrator and wind rudder all are bearing in, following rail frame, cause the structure of its frame huge, the difficult configuration that adapts to high-power wind motor, and the cost of equipment is increased.

Summary of the invention:

Technical problem to be solved by this invention is, a kind of improved wind motor with wind-guiding device is provided, and it can improve the capacity usage ratio of device, the simplified apparatus structure, and reduce manufacture cost.

For the technological scheme that solves the problems of the technologies described above employing is, the conflux guide plate of concentrator and conflux side plate have two plate bodys at least, each plate body is provided with the vertical axle that is extended through lower fulcrum bar, and each plate body can be provided with an elastic element between each vertical shaft end and each plate body around the axle swing of hanging down; Wind rudder and concentrator are installed in respectively on the upper and lower reversing frame; Upper and lower reversing frame is around on the upper and lower end plate of upper bracket, and can upper and lower relatively end plate swing.

The structure of mat polylith conflux guide plate of the present invention, conflux side plate, make the airspeed in the afflux air channel obtain the higher adjusting of sensitivity, thereby can obviously improve the capacity usage ratio of device, and its regulation structure is also greatly simplified, and the upper bracket of device and the configuration of reversing frame are dwindled the physical dimension of whole device, weight reduces, both saved fabricating cost, the wind motor with wind-guiding device that can adapt to various power again uses, the exploitation of favourable organization plan and promoting the use of.
