a double-vertical-axis wind-guiding type wind driven generator comprises a supporting frame and two groups of rotary impellers vertically arranged on the inner side of the supporting frame, wherein a triangular baffle is arranged right in front of each rotary impeller and comprises a left wind shielding surface and a right wind shielding surface, each wind shielding surface comprises two wind shielding plates, and the two wind shielding plates are respectively a fixed plate arranged on the inner side and a sliding plate arranged on the outer side; an air gathering port is arranged right in front of the triangular baffle, the bottom of the air gathering port is connected with an air guide pipeline, and the air guide pipeline vertically surrounds the rotary impeller; the sliding plate is connected with the plane of the supporting frame where the sliding plate is located through the hydraulic lifting column and slides left and right under the action of the hydraulic lifting column.

Further, the rotating impeller is connected with a generator and drives the generator to generate electricity when rotating.

Further, the support frame is connected with the rotary impeller through a central shaft.

Furthermore, a supporting base is arranged below the supporting frame.

Preferably, the tuyere collection opening is funnel-shaped.

Compared with the prior art, the beneficial effects of the utility model reside in that:

under the condition of about equal generated energy, the utility model discloses huge vane type aerogenerator's super-large-scale blade is compared to the rotary impeller external diameter, and the external diameter estimation only has about one fifth of the former, need not make huge blade, has easy manufacturing, the transportation of being convenient for, easily installation reduces the advantage of whole costs.

The utility model discloses the whole shared space of equipment is less, easily makes, transports, installation and maintenance, and because very big reduction the turbulent flow for wind energy utilization improves by a wide margin.

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. 1-3, 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 utility model discloses the inside part of face of keeping out the wind of triangle-shaped baffle is fixed, and outside part is portable. 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 equal generated energy, the utility model discloses huge vane type aerogenerator's that 3 external diameters of rotary impeller compare, the external diameter estimation only has about one fifth of the former, need not make huge vane, has easy manufacturing, the transportation of being convenient for, easily installs, reduces the advantage of whole costs.

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

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
