Detailed Description

In order to make the technical solutions of the present invention better understood and implemented by those skilled in the art, the present invention is further described with reference to the following specific examples, which are provided for illustration only and are not intended to limit the present invention.

As shown in fig. 1-3, the double-vertical-axis wind-guiding type wind turbine includes a supporting frame 1 and two sets of rotating impellers 3 vertically arranged on the inner side of the supporting frame, a triangular baffle is arranged in front of the rotating impellers 3, the triangular baffle includes a left wind-shielding surface and a right wind-shielding surface, each wind-shielding surface includes two wind-shielding plates, and the two wind-shielding plates are respectively a fixed plate 6 arranged on the inner side and a sliding plate 7 arranged on the outer side; an air gathering port 8 is arranged right in front of the triangular baffle, the bottom of the air gathering port 8 is connected with an air guide pipeline 9, and the air guide pipeline 9 vertically surrounds the rotary impeller 3; the sliding plate 7 is connected with the plane of the supporting frame 1 on which the sliding plate is arranged through the hydraulic lifting column 5 and slides left and right under the action of the hydraulic lifting column 5; a supporting base 4 is arranged below the supporting frame 1, and the supporting frame 1 is connected with the rotary impeller 3 through a central shaft 2. The rotary impeller 3 is connected to a generator (not shown in the figure) and drives the generator to generate electricity when it rotates.

The inner part of the wind shielding surface of the triangular baffle plate is fixed, and the outer part of the wind shielding surface of the triangular baffle plate is movable. When the wind power is normal, the external sliding plate 7 moves to the inside, so that the wind can blow the external effective part of the rotary impeller 3 to push the rotary impeller 3 to operate and drive the generator to generate electricity. Set up a infundibulate wind gathering mouth 8 in the positive front of triangle-shaped baffle, the guide blows in the wind-force at the rotatory impeller 3 back and blows to one side in addition of rotatory impeller 3 through gathering wind guide duct 9 of 8 bottoms in wind mouth, and the front of rotatory impeller 3 is just so all converted into effective thrust, consequently can avoid wind-force to blow to two rotatory impellers 3 inboard production resistance, very big improvement wind energy utilization ratio.

When the wind force is too large, such as a typhoon, the wind force may generate too large thrust to the rotary impeller 3, and thus the rotary impeller 3 may be damaged. At this time, the sliding plate 7 is moved outward to reduce the wind force blowing into the outside of the rotary impeller 3, thereby reducing the thrust force, protecting the rotary impeller 3, and equalizing the power generation amount.

The external sliding plate 7 and the air gathering port 8 can be completely closed, and the rotating impeller 3 is stopped due to no wind power, so that the rotating impeller 3 and other related equipment can be maintained conveniently.

Under the condition of about the same generating capacity, compared with the ultra-large blade of the giant-blade wind driven generator, the outer diameter of the rotary impeller 3 is estimated to be about one fifth of that of the ultra-large blade of the giant-blade wind driven generator, the giant-blade wind driven generator does not need to be manufactured, and the large-blade wind driven generator has the advantages of easiness in manufacturing, convenience in transportation, easiness in installation and reduction in overall cost.

The wind power generation device has the advantages of small occupied space of the whole device, easiness in manufacturing, transporting, installing and maintaining, and greatly improved wind energy utilization rate due to greatly reduced turbulent flow.

The details of the present invention not described in detail are prior art.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
