本实用新型公开了一种风力发电机半球形风叶的改进结构，所述风力发电机为垂直轴风力发电机，其主轴上固定有多个呈水平枝状伸展的中空的半球形风叶，半球形风叶的球面底部截有圆形、方形或其它几何形状的开口；与所截球面部分形状相同、稍大于或稍小于所截球面部分的活动翻板，通过开口上方的活页固定在内球面并覆盖在开口上；外球面上靠近开口周边固定有多个支架，每个支架上固定有垂直伸向开口的缓冲棒，其靠近开口内沿，端部略向开口内伸出。上述结构由于在半球形风叶的球面底部采用了活动翻板结构，消除了位置相对的两个半球形风叶之间的风力抵销影响，从而保证发电机顺利运转发电，另外，缓冲棒的设置，可以避免活动翻板盖下时与风叶底部的开口边缘碰撞产生噪音。
The utility model discloses an improved structure of a hemispherical wind blade of a wind power generator. The wind power generator is a vertical axis wind power generator, and a plurality of hollow hemispherical wind blades extending in a horizontal branch shape are fixed on the main shaft. The bottom of the spherical surface of the hemispherical fan blade is cut with a circular, square or other geometric opening; the movable flap with the same shape as the cut spherical part, slightly larger or slightly smaller than the cut spherical part, is fixed by the loose leaf above the opening The spherical surface covers the opening; multiple brackets are fixed on the outer spherical surface close to the periphery of the opening, each bracket is fixed with a buffer rod extending vertically toward the opening, which is close to the inner edge of the opening, and the end slightly protrudes into the opening. The above-mentioned structure adopts a movable flap structure at the bottom of the spherical surface of the hemispherical fan blade, which eliminates the wind force offset effect between the two hemispherical fan blades in opposite positions, thereby ensuring the smooth operation of the generator to generate electricity. In addition, the buffer rod It can avoid the noise caused by collision with the edge of the opening at the bottom of the fan blade when the movable flap cover is lowered.
Description
Technical field
The utility model relates to technical field of wind power generator, particularly a kind of improvement structure of wind-driven generator hemisphere fan blade.
Background technique
The vertical axis aerogenerator that existing hemisphere fan blade horizontally rotates, it is the good facility of energy-conservation generating under the gentle breeze state, be fixed with a plurality of hemisphere fan blades that are the hollow of the dendritic stretching, extension of level on its housing, its sphere is close-shaped, because the resistance of air that single hemisphere fan blade is subjected to is less, under the natural wind gentle breeze state, also can under promoting, wind-force horizontally rotate, drive engine power generation, but when wind-force is bigger or in the long-term bigger area of wind-force, because wherein per two position opposed hemispherical shape fan blades position of accepting wind-force is almost opposite, one in inner ball surface, one at outer spherical surface, like this, the two suffered powerful wind-force produces payment mutually, and all fan blades rotate difficulty on the contrary as a result, thereby can't reach the effect of wind-power electricity generation, have much room for improvement.
The model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of improvement structure of wind-driven generator hemisphere fan blade is provided, and can reach gentle breeze or high wind and can both make the generator good result of running smoothly.
The technical solution of the utility model is: the improvement structure that a kind of wind-driven generator hemisphere fan blade is provided, described wind-driven generator is a vertical axis aerogenerator, be fixed with a plurality of hemisphere fan blades that are the hollow of the dendritic stretching, extension of level on its main shaft, the sphere of hemisphere fan blade bottom is cut circle, the opening of square or other geometrical shape; Identical with institute truncated-spherical partial shape, as to be a bit larger tham or to be slightly smaller than institute's truncated-spherical part drop in leaf, the loose-leaf by the opening top is fixed on inner ball surface and covers on the opening; Be fixed with a plurality of supports near open circumferential on the outer spherical surface, be fixed with the fender pile that vertically stretches to opening on each support, it is near edge in the opening, and slightly stretch out in opening the end.
The improvement structure of aforesaid wind-driven generator hemisphere fan blade, support is a groove shapes, fender pile passes groove, and fastens between the twice trough rim of groove by rivet grip.
The improvement structure of the wind-driven generator hemisphere fan blade of said structure, because the drop in leaf structure has been adopted in the sphere bottom at the hemisphere fan blade, eliminated the wind-force payment influence between two relative hemisphere fan blades of position, the generating thereby the assurance generator turns round smoothly, in addition, the setting of fender pile can be avoided drop in leaf to cover the edge of opening collision of following time bottom fan blade and produce noise.
Description of drawings
Below in conjunction with the drawings and specific embodiments structure of the present utility model and advantage are further described.
Fig. 1 is hemisphere fan blade (1) the part stereogram when raising;
Fig. 2 is the stereogram of hemisphere fan blade (1) when covering opening (2) and going up;
Fig. 3 is the stereogram of hemisphere fan blade (1);
Fig. 4 is the user mode figure of existing hemisphere fan blade device.
Embodiment
Referring to Fig. 1, Fig. 2, Fig. 4, a kind of improvement structure of wind-driven generator hemisphere fan blade is provided, described wind-driven generator is a vertical axis aerogenerator, be fixed with six hemisphere fan blades 1 that are the hollow of the dendritic stretching, extension of level on its main shaft, the sphere bottom of hemisphere fan blade 1 is cut circular opening 2.Identical with institute truncated-spherical partial shape, be a bit larger tham the drop in leaf 3 of institute's truncated-spherical part, the loose-leaf by opening 2 tops is fixed on inner ball surface and covers on the opening 2.In the use, when being in gentle breeze state following time, the drop in leaf 3 of all hemisphere fan blades 1 all covers on the opening 2, hemisphere fan blade 1 normally rotates, the generator operation generating, when being in high wind state following time, per two position opposed hemispherical shape fan blades 1, one of them accepts wind-force for inner ball surface, and drop in leaf 3 covers on the opening 2, and hemisphere fan blade 1 is subjected to the promotion of powerful wind-force, another then accepts wind-force for outer spherical surface, its drop in leaf 3 is blown open by high wind and starts, and high wind passes opening 2, and the wind-force that whole hemispherical fan blade 1 is subjected to becomes less, also the wind-force of promptly repealing by implication with previous hemisphere fan blade 1 is less, thereby can eliminate the influence that the two wind-force is repealed by implication substantially, guarantee the normal fast rotational of whole fan blade device, also just guarantee the normal operation generating of generator.Above-mentioned opening 2 also can be square or other geometrical shape, and drop in leaf 3 also can be slightly smaller than institute's truncated-spherical part, and using effect is consistent.
Referring to Fig. 3, be fixed with three supports 4 near opening 2 peripheries on the outer spherical surface, be fixed with the fender pile 5 that vertically stretches to opening on each support 4, it is near edge in the opening 2, and slightly stretch out in opening 2 end.Specifically, support 4 is a groove shapes, and fender pile 5 passes groove, and fastens between the twice trough rim of groove by rivet grip.When the movable flip 3 of hemisphere fan blade 1 is covered under sheds 2,, can avoid moving turnover panel 3 lid opening 2 peripheral collisions of following times bottom fan blade to produce noise owing to there is fender pile 5 to withstand.
The foregoing description is a preferred embodiment of the present utility model, and all and the similar structure of the utility model and the equivalence of being done change, and all should belong to protection category of the present utility model.
