Abstract
The utility model discloses a vertical-axis power fan. The fan comprises a pedestal, a main shaft and a blade assembly. The main shaft is arranged on the pedestal. After an improvement, the blade assembly comprises blade frames, blade shafts, blades and blade turnover limiting stoppers, wherein the blade frames are symmetrically fixed onto two sides of the main shaft through connecting plates; each blade shaft penetrates through the main shaft and two blade frames in a horizontal direction and is in rotational fit with the two blade frames and the main shaft; the blades with acting faces vertical to each other are respectively fixed onto the two sides of each blade shaft; and the blades in the same blade frame are parallel to each other. Based on a characteristic that wind has extremely strong area-identifying capability, when the blade on one side of each blade shaft has the maximum windward area, the resistance to the other blade is basically zero, so that the resistance difference of the wind is maximized and the aim of increasing the utilization ratio of the wind is achieved.
Description
Technical field
The utility model relates to the wind energy driven fan of a kind of blower fan, particularly a kind of vertical shaft, belongs to technical field of wind power generation.
Background technique
Wind-driven generator is divided into horizontal axis and vertical shaft according to the main shaft installation position, uses horizontal axis wind-driven generator comparatively generally by contrast.Although the horizontal axis generator is used general, there are some problems on the structure, as: need to go off course, oar etc. is facingd the wind and the control windward side increases the structure of resistance difference, this makes the generator Structure complexity, it is many and cause fault easily to take component.Based on horizontal axis generator Structure defective, in recent years, the vertical-axis generators technical development is rapid, uses increasingly extensive.Vertical-axis generators can increase windage by the optimal design to blade structure, and it is poor to improve wind resistance, and because of need not driftage, change sizing device, structure is simple relatively.The vertical-axis generators key technology is the design of blade, and the blade structure shape directly influences Wind Power Utilization efficient.Therefore improving blade structure, improving wind energy utilization is the constantly problem of research of Professional visitors.
The model utility content
The utility model is used to overcome the defective of prior art and the vertical shaft driven fan that a kind of wind resistance difference is big, wind energy utilization is high is provided.
The alleged problem of the utility model is solved by following technological scheme:
A kind of vertical shaft driven fan, its formation comprises pedestal, main shaft and blade assembly, main shaft is installed on the pedestal, its specialization is: described blade assembly comprises blade frame, sharf, blade and blade upset positive stop, wherein, blade frame is fixed on the main shaft both sides by the connecting plate symmetry, each sharf along continuous straight runs passes main shaft and two blade frames and is rotatably assorted with two blade frames, main shaft, at the orthogonal blade of each sharf both sides difference fixation face, the blade installation position that is positioned at same blade frame is to identical.
Above-mentioned vertical shaft driven fan, described each blade upset positive stop is fixed on the blade frame place, and the lower side of its position during with the vertical state of each blade is corresponding.
Above-mentioned vertical shaft driven fan, described sharf is positioned at blade top, and wherein the sharf axis is apart from blade upper edge size a: sharf is 4～6:7 apart from blade lower edge size b.
Above-mentioned vertical shaft driven fan, described blade assembly are provided with the 2-4 cover, and each relative main shaft diameter of blade frame of overlapping in the blade assembly is axially just straggly to even setting, relative main shaft.
The utility model is poor at improving the fan blade wind resistance, and then improves wind-driven generator Wind Power Utilization problem and designed a kind of vertical shaft driven fan, and this blower fan mainly improves and is embodied on the blade assembly structure.Described blade assembly structural design has extremely strong these characteristics of area ability to see things in their true light based on wind, hard-wired two orthogonal blades on every sharf, and the rotation angle to blade is limited, like this, when a blade blowing area in each sharf is maximum, the resistance of another blade is zero substantially, realizes the maximization of wind resistance difference, and then reaches the purpose that improves wind energy utilization.In addition, the utlity model has simple in structure, be easy to realize characteristics such as fabricating cost is cheap, of many uses.In fields such as generating, windmill, air pump, wind-powered electricity generation architecture-integrals, have a good application prospect.

The number in the figure implication is as follows: 1. pedestal; 2. main shaft; 3. blade frame; 4. sharf; 5. blade; 6. blade upset positive stop; 7. connecting plate; 8. bearing.
Embodiment
Referring to Fig. 1, the utility model formation comprises pedestal 1, main shaft 2 and blade assembly, and main shaft vertically is installed on the pedestal.Every cover blade assembly comprises two blade frames 3, two blade frames are fixed on the main shaft both sides by connecting plate 7 symmetries, several sharf 4 along continuous straight runs pass main shaft and two blade frame sides and form and be rotatably assorted with two blade frame sides, main shaft, with the orthogonal blade 5 of fixation face respectively, be positioned at blade installation position on the same blade frame in each sharf both sides to identical; Lower side position on blade frame during the vertical state of corresponding each blade is provided with upset positive stop 6, and when blade was positioned at vertical state, the lee face of blade touched with the upset positive stop.Described blade assembly is provided with the 2-4 cover, and each overlaps blade assembly according to identical structure setting, and each blade frame 3 relative main shaft diameter of overlapping in the blade assembly is axially just straggly to even setting, relative main shaft.In the embodiment shown in fig. 1, blade assembly is provided with two covers, and totally four blade frames are provided with five sharfs in every cover blade assembly.
Referring to Fig. 3, sharf 4 is positioned at blade top, making blade is that the boundary has formed bottom area two pieces greater than the top area with the sharf axis, wherein, the sharf axis is apart from blade upper edge size a: sharf is 4～6:7 apart from blade lower edge size b, this structure blade has formed the poor of time big upward small size, guarantees that blade overturns under the wind-force effect.For reducing surface friction drag, be provided with bearing 8 between sharf and the blade frame.
Referring to Fig. 1, Fig. 2, working procedure of the present utility model is as follows: wind direction is shown in arrow among Fig. 2, and wind is to blade, and blade 5 relative sharf 4 upsets drive main shaft 2 simultaneously and clockwise rotate.Main shaft right side blade frame is the passive blade framework, the blade frame in main shaft left side is the active blade framework, main shaft right side blade turn to level under the wind-force effect, main shaft left side blade is vertical state under the effect of wind-force and upset positive stop 6 simultaneously, because main shaft left side blade is vertical with wind direction, main shaft left side blade blowing area maximum, the parallel blowing area minimum of main shaft right side blade (being zero in theory) with wind direction, the wind resistance difference of main shaft and arranged on left and right sides blade realizes maximization; The blade of both sides is the upset transition state before and after the main shaft.Along with main shaft rotates, the blade circulation upset in every cover blade assembly is rotated thereby drive main shaft, makes blower fan generating acting.
