Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described with reference to the following specific embodiments, which are provided as illustration only and are not intended to limit the present invention.

As shown in fig. 1-4, the present invention relates to a wind-guiding type double-circulation wind power generation device, wherein a large-sized rotary impeller perpendicular or parallel to the ground is fixed on a bottom bracket 10, the rotary impeller is arranged in a closed outer cylinder 6 and comprises a blade 5, a middle cylinder 13 and an inner cylinder 14, the inner side of the blade 5 is fixed on the middle cylinder 13, and the inner cylinder 14 is arranged in the middle cylinder 13. The structure of the blade 5 is unique, and is a series of wind collecting hopper structures, the mouth is large, the bottom is small, and the bottom is provided with a hole which leads to the inside of the middle cylinder 13.

A wind-gathering funnel 9 is arranged right in front of the rotary impeller and fixed on the outer wall of the outer cylinder 6. The side of the wind gathering funnel 9 is provided with a first movable sliding plate 4 at the bottom thereof, which is controlled by the second lifting column 3 to release unnecessary wind.

The air inlet is arranged at the positive wind-receiving surface of the rotary impeller, the corresponding part of the outer cylinder 6 is provided with an air inlet, and an arc-shaped movable plate 1 is arranged and can move left and right under the action of a first lifting column 2 (a hydraulic rod) so as to control the air inlet amount.

The bottom of the air gathering funnel 9 is provided with a second movable sliding plate 8, the third lifting column 7 is used for adjusting the air inlet amount of the air gathering port, and the air gathering port can be completely closed when the air amount is too large or equipment is maintained.

The utility model discloses another bright characteristics of structure are two inner tube designs, form relative enclosure space between two section of thick bamboo of middle section of thick bamboo 13 and inner tube 14 to the wind of blowing in from the receipts wind bucket type blade 5 of rotatory impeller can get into this space and circulate, so that realize the absorption maximize of wind-force energy.

The middle cylinder 13 and the outer cylinder 6 form a first cycle, the middle cylinder 13 and the inner cylinder 14 form a second cycle, and the double-cycle structure can greatly improve the collection efficiency of wind energy.

When wind power is general, the arc-shaped movable plate 1 of the air inlet gate is opened, so that the wind power can blow to the positive wind-receiving surface of the rotary impeller, and the rotary impeller is pushed to operate to drive the generator to generate power. The second movable sliding plate 8 at the bottom of the wind gathering funnel 9 is also fully opened, so that the resistance wind at the back of the rotating impeller can change the direction through the wind gathering funnel 9, becomes beneficial wind power and increases the thrust. Therefore, resistance generated by wind blowing to the back of the rotating impeller can be avoided, and the wind energy utilization rate is comprehensively improved.

When the wind force is too large, for example, typhoon or the like comes, too large wind force may generate too large thrust to the rotary impeller, which may cause damage to the rotary impeller. At this time, the positive wind force blown into the rotary impeller can be reduced by moving the arc-shaped movable plate 1 of the air inlet large door, and the second movable sliding plate 8 of the air inlet at the bottom of the air collecting funnel 9 can be closed, so that the wind thrust is reduced, the rotary impeller is protected, and the balanced generating capacity is kept.

The movable plate 1 of the air inlet gate and the air gathering funnel 9 can be completely closed, and at the moment, the rotary impeller is in a stop state due to no wind power pushing, so that the rotary impeller and other equipment are very convenient to maintain. But at this point the side doors of the hurricane funnel should be opened to bleed.

Compare several first wind-guiding type wind power generation set of the applicant, the utility model discloses the intention of scheme lies in having changed 5 shapes of blade of rotatory impeller, has become the wind-collecting bucket structure with blade 5 by the arc to the increase has set up an inner tube 14, constitutes relative confined space between the inside binocular (middle tube 13 and inner tube 14), forms inner loop wind-force push system, is used for further improving the efficiency of collecting the wind energy.

The utility model discloses under the condition of about equal generated energy, huge vane type aerogenerator's that rotary impeller external diameter compares super large-scale blade, the external diameter estimation only has about one fifth of the former, has easy manufacturing, advantage with low costs because need not make huge blade. The whole occupied space of the equipment is small, the equipment is easy to transport and convenient to install and maintain. Because the turbulence is greatly reduced, the wind direction is effectively and reasonably guided, and the wind energy utilization rate is greatly improved.

The utility model discloses a key point and guard point:

the wind guide type capable of adjusting the air intake changes the rotating impeller blade 5 from an arc-shaped plate into a wind collecting hopper structure, and an inner cylinder 13 is added to form a cylindrical rotating impeller wind power generation device of a closed internal wind power circulation system, so that the wind energy collection efficiency is greatly improved.

The present invention is not described in detail in the prior art.
