Detailed Description

In order to make the technical solutions of the present invention better understood and enable those skilled in the art to practice the present invention, the following embodiments are further described, but the embodiments are only illustrative and not intended to limit the present invention.

The double-horizontal-axis wind-guiding type wind driven generator shown in fig. 1-3 comprises a supporting frame 1 and two groups of rotating impellers 3 arranged in parallel on the inner side of the supporting frame, wherein a triangular baffle is arranged right in front of the rotating impellers 3, the triangular baffle comprises two groups of symmetrically arranged slope type baffles, and the slope type baffles comprise a fixed plate 6 and a sliding plate 7; 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 up and down under the action of the hydraulic lifting column 5; the wind power generation device is characterized in that a funnel-shaped wind gathering port 8 is arranged right in front of the triangular baffle, the bottom of the funnel-shaped wind gathering port 8 is connected with a wind guide pipeline 9, and the wind guide pipeline 9 surrounds the other side of the rotary impeller 3 from the bottom of the funnel-shaped wind gathering port 8 along the horizontal direction.

The rotary impeller 3 is fixed to the support frame 1 through the central shaft 2. A supporting base 4 is arranged below the supporting frame 1. 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 fixing plates 6 at the upper end and the lower end of the slope-shaped baffle plate are fixed, and the two sliding plates 7 in the middle can move up and down. When the wind power is normal, the sliding plate 7 moves into the wind power, so that the incoming wind can blow the exposed effective stress part of the rotary impeller 3, and the rotary impeller 3 is pushed to operate to drive the generator to generate power. Set up a infundibulate wind trap door 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 the wind-guiding pipeline 9 of 8 bottoms in the funnel shape wind trap door, and the positive incoming wind of rotatory impeller 3 just so all turns into effective thrust almost, can avoid wind-force directly to blow the inboard production resistance of two rotatory impellers 3, has certainly greatly improved wind energy utilization.

When the wind force is too large, such as typhoon, the wind force is too large, and an excessive thrust is generated to the rotary impeller 3, which may damage the rotary impeller 3. At this time, the sliding plate 7 is moved upward to reduce the wind force blowing to the outside of the rotary impeller 3, thereby reducing the thrust force, protecting the rotary impeller 3, and balancing the power generation amount.

The sliding plate 7 and the funnel-shaped air gathering port 8 can also be completely closed, and at the moment, the rotating impeller 3 is in a stop state due to no wind power pushing, so that the rotating impeller 3 and other related equipment are very convenient to maintain.

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, and the giant-blade wind driven generator does not need to be manufactured, so that the rotary impeller has the advantages of easiness in manufacturing and transporting and low cost. The whole occupied space of the equipment is small, and the installation and the maintenance are convenient; greatly reduces the turbulent flow and greatly improves the wind energy utilization rate.

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.
