Abstract
The utility model relates to a horizontal axis windmill with a wind-speed rudder, which comprises a generator, a sliding bearing and rotor wings, wherein the generator is movably connected with a wind-speed rudder rod through a connecting piece; the wind-speed rudder is arranged on the tail end of the wind-speed rudder rod; the wind-speed rudder rod is connected with a rocker arm; the rocker arm is connected with a pull rod through a connecting shaft; and the pull rod is connected with a sleeve of the sliding bearing. The horizontal axis windmill with the wind-speed rudder is easy to process, has stable performances, a long service life and is low in cost, and meets the requirement of a small windmill. The efficiency of the small windmill is improved, the starting wind speed is reduced, the wind proof capacity is strong, and the speed adjustable range is reduced.
Description
Technical field
The utility model relates to a kind of mechanical adjustable speed drive, relates in particular to a kind of horizontal axis windmill that the wind speed rudder is housed.
Background technique
The speed regulating mechanism of present large-scale windmill has two kinds of electronic speed governing and Hydraulic Adjustable Speeds, is controlled by air velocity transducer, automatic control circuit or computer, and the pitch that is used for regulating rotor is adjusted the rotating speed of windmill.Small-sized windmill is because volume is not suitable for installing above two kinds of speed regulating mechanisms for a short time; The rotor angle is that what to be fixed is to come speed governing or with going off course speed governing with brake; During with the driftage speed governing; Cause the rotor high speed rotating can produce gyroscopic effect, to the damage that rotor has warping force to cause, windmill efficient is low, wind loading rating is poor, it is high to start wind speed.Regulate windmill speed thereby also have a kind of dependence centrifugal force to regulate the rotor angle, though efficient has improved, wind loading rating has also improved, thus must the rotating speed height just to understand the deflection speed adjustable range to blade to a certain degree bigger than normal.
Summary of the invention
The utility model is to the problem that exists in the above-mentioned existing technology; Foot piece and wind direction rudder to small-sized windmill improve; A kind of horizontal axis windmill that the wind speed rudder is housed is provided; With the angle that the wind speed rudder is regulated rotor, solved the efficient that small-sized wind wheel blade fixedly causes low, start that wind speed is high, the problem of wind loading rating difference, also solved the big problem of centrifugal displacement windmill speed adjustable range.
To achieve these goals, the technological scheme of the utility model is following:
Comprise generator, sliding bearing and rotor, generator flexibly connects through link and wind speed rudder stock, and the tail end of wind speed rudder stock is provided with the wind speed rudder; The wind speed rudder stock is connected with rocking arm, and rocking arm is connected with pull bar through coupling shaft, and pull bar links to each other with the sliding bearing overcoat.
Described wind speed rudder is wing.
The top of described wind speed rudder is provided with rudder.
Described wind speed rudder stock is provided with counterweight.
The utility model has the advantages of as follows:
1, wind speed rudder, rocking arm, counterweight, coupling shaft etc. all are mechanical structure, processing easily, stable performance, long service life, and cost is low, is fit to the needs of small-sized windmill.Improved small-sized windmill efficient, reduced the startup wind speed, wind loading rating is strong, and has reduced speed adjustable range.
When 2, the rotating speed of rotor did not also change owing to inertial force when wind speed changes, the wind speed rudder had changed the position and has begun to adjust the pitch of rotor, so the rotating speed of windmill is more steady, rotor, generator and voltage stabilizer is protected has prolonged working life.
Description of drawings
Below, in conjunction with accompanying drawing, the utility model is elaborated.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the plan structure schematic representation of the utility model.
Among the figure, 1, the wind speed rudder, 2, rudder, 3, the wind speed rudder stock, 4, rocking arm, 5, coupling shaft, 6, pull bar, 7, counterweight, 8, generator, 9, sliding bearing, 10, connecting rod, 11, the rotor shaft rocking arm, 12, the slurry hub, 13, rotor.
Embodiment
Embodiment
The afterbody that wind speed rudder 1 is movably arranged on generator 8 can move up and down, and wind speed rudder 1 has certain aerofoil profile, and wind can produce lift upwards when moving, and the lift different heights that the size of wind produces is also different.The front of wind speed rudder stock 3 is added with counterweight 7, makes wind speed rudder 1 that corresponding height arranged under various wind speed through the weight of regulating counterweight 7, and wind speed rudder stock 3 is installed with Rocker arm 4, coupling shaft 5 and pull bar 6 with generator 8 joints; Make moving up and down of wind speed rudder 1 be transformed into the horizontal motion of pull bar 6; The overcoat of sliding bearing 9 is connected with pull bar 6, and cover is spline in the described sliding bearing 9, and the rotation that matches with the generator shaft spline also can reciprocatingly slide; The rotor shaft rocking arm 11 of applying mechanically connecting rod 10 and rotor 13 in the sliding bearing flexibly connects; Rotor shaft is fixed on the slurry hub 12 and turns, and when wind speed rudder 1 moves up and down, will drive pull bar 6, sliding bearing 9, connecting rod 10 horizontal motions, through sliding bearing 9, connecting rod 10, rotor shaft rocking arm 11 seesawing of sliding bearing 9 is transformed into the radially rotation of rotor 13 then; Change the different pitch of rotor 13 under different wind speed; The pitch of rotor 13 has changed rotating speed and has also just changed, thereby the rotating speed of adjustment rotor 13 remains at the optimum state, thereby has realized adjusting through wind speed rudder 1 purpose of the rotating speed of rotor 13 and generator 8; Improve the efficient of rotor, strengthened wind loading rating.
Its protection domain does not receive the restriction of specific embodiment, is as the criterion with claim.
