The wind power generation device disclosed by the utility model enlarges and reduces the stress area of blades of a vertical shaft wind power generator in such a way that the movable blade can be opened or closed with the opposite direction change of air flows and the blades by adopting the combination of the fixed blade and the movable blade, thereby increasing the power generation efficiency by increasing the efficiency of the blades of the vertical shaft wind power generator and solving the problem of self starting of the vertical shaft wind power generator.

Description

Wind generating unit

Technical field

The utility model relates to the field of wind-power electricity generation, especially a kind of wind generating unit.

Background technique

Utilize wind energy power mainly to use wind power generating set, i.e. horizontal axis wind-driven generator and vertical axis aerogenerator at present.Horizontal axis lift-type wind-driven generator is owing to reasons such as the technology maturation application time are long, extensive use, and mostly especially large-scale powerful wind power generating set is the horizontal axis lift-type; Quiet effective, the advantages such as center of gravity is low, space hold is little, easy care of vertical shaft-type wind power generation machine; But the starting performance difference of vertical axis rotor also is present common recognition in the industry, fails to obtain to popularize and large-scale application, particularly for Darrieus formula Φ type wind wheel; There is not the self-starting ability fully; Much wind no matter all needs a power source to drive wind wheel earlier and turns to certain speed and could start, though vertical shaft resistance type generator startability is good; But also can't be applied to high-power generator because of efficiency, this also is the major reason that the restriction vertical axis aerogenerator is used and developed.

The model utility content

The technical problem that the utility model will solve is: in order to overcome the above-mentioned middle problem that exists, a kind of wind generating unit is provided, its project organization is reasonable and generating efficiency is high.

The utility model solves the technological scheme that its technical problem adopted: a kind of wind generating unit; Comprise base and vertical vertical shaft on base; Be equipped with the axle sleeve that is rotationally connected with vertical shaft on the described vertical shaft; Be evenly distributed at least one supporting frame on the axle sleeve outer side wall; Every supporting frame end all is connected with blade assembly; Rotatingshaft on described blade assembly comprises the stator blade that is connected with the supporting frame end and is arranged on the stator blade leading edge and the moving vane that is connected with rotatingshaft, described moving vane are hinged through rotatingshaft and stator blade and are arranged on the stator blade inboard, and moving vane is along with airflow direction changes and closure or openness.

In order to make generating efficiency reach maximum; Be evenly distributed in four supporting frames on the described axle sleeve outer side wall; Four supporting frame ends connect four blade assemblies; All be connected with movable rod between two moving vanes on two blade assemblies of opposing side, can control the unlatching and the closure of blade better each other, make that the action of blade is more smooth-going.

The beneficial effect of the utility model is: described wind generating unit; Adopt the combination of stator blade and moving vane; Moving vane can closure or openness increase and reduce the lifting surface area of vane of vertical shaft wind-driven generator with this with the opposite direction variation of air-flow and blade, and then the efficient of raising generator blade improves generating efficiency; Can solve simultaneously the self-starting problem of vertical axis aerogenerator; It has combined the advantage of resistance type and lift-type wind-driven generator, and the high usage of existing resistance type wind-driven generator has the high efficiency of lift power type wind-driven generator again.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is first embodiment's of the utility model a structural representation;

Fig. 2 is second embodiment's of the utility model a structural representation.

1. bases among the figure, 2. vertical shaft, 3. axle sleeve, 4. supporting frame, 51. stator blades, 52. rotatingshafts, 53. moving vanes, 6. movable rod.

Embodiment

Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

Embodiment 1:

Wind generating unit as shown in Figure 1 comprises base 1, is fixedly connected with vertical shaft 2 on the base 1; Be equipped with the axle sleeve 3 that is rotationally connected with vertical shaft 2 on the vertical shaft 2; Be evenly distributed in 4, four supporting frame 4 ends of four supporting frames on axle sleeve 3 outer side walls and all be connected with four stator blades 51, the leading edge of stator blade 51 is provided with rotatingshaft 52; Be connected with moving vane 53 on the rotatingshaft 52, moving vane 53 is hinged through rotatingshaft 52 and stator blade 51 and is arranged on stator blade 51 inboards.

Embodiment 2:

Wind generating unit as shown in Figure 2; Comprise base 1, be fixedly connected with vertical shaft 2 on the base 1, be equipped with the axle sleeve 3 that is rotationally connected with vertical shaft 2 on the vertical shaft 2; Be evenly distributed in four supporting frames 4 on axle sleeve 3 outer side walls; Four supporting frame 4 ends all are connected with stator blade 51, and the leading edge of stator blade 51 is provided with rotatingshaft 52, is connected with moving vane 53 on the rotatingshaft 52; Be connected with movable rod 6 between two moving vanes 53 of opposing side; Movable rod 6 can be controlled the unlatching and the closure of blade better each other, makes that the action of blade is more smooth-going, and moving vane 53 is hinged through rotatingshaft 52 and stator blade 51 and is arranged on stator blade 51 inboards.

The wind generating unit of the utility model, this installs in use, and wind is on any blade assembly wherein, and moving vane 53 is opened by wind and stator blade 51 forms several angles; After supporting frame 4 drove 90 ° of angles of blade assembly rotation, moving vane 53 opened, and this moment, moving vane 53 lifting surface areas were maximum; After supporting frame 4 drove 90 ° of angles of blade assembly rotation again, moving vane 53 is in the face of wind direction, and was moving and closed by wind; After supporting frame 4 drove 90 ° of angles of blade assembly rotation again, moving vane 53 was closed fully, and this moment, the wind-exposuring area of moving vane 53 was minimum, the resistance minimum, and this moment, one of them blade assembly was accomplished a wind-engaging circulation, so back and forth carried out the wind-engaging do action.
