Abstract
The utility model relates to a windmill, in particular to a horizontal-shaft resistance difference double-rotor windmill, which consists of a tower, a board, a connection assembly between the tower and the board, a horizontal shaft, two resistance difference rotors which are symmetrically arranged on two ends of the horizontal shaft, a bearing assembly which is used for supporting the horizontal shaft on the board, a transmission gear, a transmission case, a power generator and a pair of wind rudders, wherein the rotors are formed by a wheel boss and three groove-shaped blades which are uniformly distributed and form an angle of 120 degrees. The windmill overcomes the torque force and the vibration, which are acted by a vertical-shaft resistance difference windmill on the tower. Since thedistance between the two rotors and the axis of the tower is compact, a horizontal spiral arm of the vertical shaft resistance difference windmill can be omitted, so that the windmill is convenient for the industrial production.
Description
Technical field:
The utility model relates to a kind of wind energy conversion system, particularly a kind of horizontal axis resistance difference type double-rotor wind power machine.
Background technique:
The wind energy conversion system of present industrial use mostly is horizontal axis propeller type wind energy conversion system greatly, and it is 30% that the utilization ratio of wind energy has only usually, and equipment cost is very high, causes cost of wind power generation to be higher than the cost of thermoelectricity generating on the contrary.Vertical shaft resistance difference type wind energy conversion system has many advantages, as the utilization ratio of wind energy height, also can start under the low velocity wind situation, need not wind apparatus or the like.But vertical shaft resistance difference type wind energy conversion system is not widely adopted industrial always, and reason is that unbalanced in the horizontal direction stressed can the producing of rotor produces torsion and vibration to fuselage and pylon, and this is difficult for solving on engineering.In addition, the horizontal rotary arm of rotor belongs to cantilever structure, avoids making on engineering as far as possible.
Summary of the invention:
In order to overcome the shortcoming of horizontal axis propeller type wind energy conversion system and vertical shaft resistance difference type wind energy conversion system, the utility model provides a kind of horizontal axis resistance difference type double-rotor wind power machine, this kind wind energy conversion system also possesses and is convenient to industry and makes, install and advantage cheaply in the high absorption efficiency that possesses wind energy.
The technological scheme that the utility model adopted is: a kind of horizontal axis resistance difference type double-rotor wind power machine, be used to support on two resistance difference type rotors that it is placed by the connection assembly between pylon, board, pylon and the board, horizontal axis, horizontal axis two ends symmetry, the board horizontal axis bearing assembly, driving gear, gearbox, generator, the wind rudder is formed, described rotor is by wheel hub and be in 120 degree equally distributed three and fan the flute profile blades and form.
The beneficial effects of the utility model are:
(1) compare with vertical shaft resistance difference type wind energy conversion system:
At first the utility model has overcome vertical shaft resistance difference type wind energy conversion system rotor substantially horizontal and has acted on torsion and vibration on the pylon.
Secondly, owing to the distance relation compactness of two rotors and pylon medial axis, avoided this cantilever structure of vertical shaft resistance difference type wind energy conversion system horizontal rotary arm.
(2) compare with horizontal axis propeller type wind motor:
At first, structure is advantages of simple more, and cost is lower.The rotor of horizontal axis propeller type wind motor is the front end that is suspended in the cabin, thereby gives downward moment of cabin front end, and this embodies more obvious on the large scale wind motor.Here it is, and why horizontal axis propeller type wind motor blade must use expensive lightweight material manufacturings such as carbon fiber.And the present invention is owing to adopt the symmetric double rotor design, thereby two-spool center of gravity can be adjusted on the medial axis of center, cabin and pylon, thereby the weight of rotor is required not have the strictness of horizontal axis propeller type wind energy conversion system.Therefore rotor blade of the present invention can adopt cheap steel pipe and coloured glaze steel, reduces equipment cost greatly.
Secondly, the utility model is wideer to the accommodation of wind.Horizontal axis propeller type wind energy conversion system is owing to be that a part (being about 1/3) with wind-force is converted into torsion, thereby more wind-force be thrust as forward on blade and fuselage, large scale computer greatly must feathering to a certain degree the time damages preventing at wind speed usually.This in addition wind energy conversion system is difficult for starting when low velocity wind.The utility model is because the thrust of wind directly promotes the blade acting, thereby the windward side of the utility model rotor will reduce 2/3 under the situation that produces identical power.Owing to be connected with steel pipe and wire rope between the adjacent blades, join integral body of three fan leafs formation in addition, strengthen the intensity of rotor greatly thereby make.Therefore but the present invention is in general high wind proper functioning.In addition, the present invention also can work under the low velocity wind situation.
Description of drawings:
Fig. 1 is the front view of wind energy conversion system.
Fig. 2 is the side view of wind energy conversion system.
Fig. 3 is the plan view of wind energy conversion system.
Fig. 4 is the structural drawing of flabellum.
Connection assembly among the figure between (1) pylon, (2) board, (3) pylon and the board, (4) horizontal axis, (5) horizontal axis two ends symmetry place resistance difference type double rotor, (6) board on be used to support the bearing assembly, (7) driving gear, (8) speedup box, (9) generator, (10) of horizontal axis to the wind rudder.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified.
Rotor is by wheel hub (11) and be in 120 degree equally distributed three steel pipe spiral arms (13) and flabellums (12) and form.
Flabellum (12) is opening is rectangle, cross section is the U font groove.It is made of steel pipe keel frame (16) and glass fibre reinforced plastics covering (17).Keel frame (16) is formed by welding D word shape steel loop (20) in the middle of three parallel steel pipe posts (19).5-30 diaphragm (21) is installed in the groove, and purpose is the absorptivity that increases wind energy, stops wind along the vallecular cavity Radial Flow, can also increase the structural strength of flabellum simultaneously.So just forming flabellum has the ability of good absorption wind energy during towards wind at opening, opening dorsad during wind because the bottom land outer surface is streamline, possesses good guide performance, thereby windage is very little.One end of flabellum is welded on the steel pipe spiral arm (13), is attached on the wheel hub (11) by steel pipe spiral arm (13).Reinforcement steel pole (14) and wire rope (15) are arranged between three blades, thereby make connection three fan leafs form an integral body, can strengthen the intensity of rotor.
Rotor is installed in the two ends of horizontal axis (4) symmetrically, and horizontal axis combines with board by the bearing assembly (6) of its both sides.In the middle of the horizontal axis driving gear (7) and braking device (8) are installed, driving gear (7) sends mechanical energy to generator (9) by speedup box (8).
It is that the center of circle horizontally rotates with pylon (1) central shaft that connection assembly (3) between pylon and the board can make board (2).Wind rudder (10) perpendicular to horizontal axis (4), is driven board (2) to wind rudder (10) and horizontally rotates and make rotor blade subtend wind direction.
