Technical field
The utility model relates to a kind of wind-driven generator, is specifically related to a kind of horizontal axis wind-driven generator revolution axis type empennage mechanism.
Background technique
Traditional small-sized horizontal axis wind-driven generator (adopting empennage to protect) need rely on empennage folding tail or driftage to reduce the rotating speed of wind-driven generator when wind speed is higher, plays the effect of regulating and protecting wind-driven generator.Common empennage operative orientation is rolled over the tail protection about being; When wind speed is higher; Receive the influence of foot piece length and fin area and foot piece angle, phenomenon slow in reacting can occur, after folding tail protection generator speed reduces, can produce the slow phenomenon of return again; Similar problem directly causes the efficient of wind-driven generator to reduce greatly, can't realize the value maximization of wind-driven generator to Wind Power Utilization.Simultaneously, the folding tail of the long-term continuity of foot piece moves, and certainly will greatly reduce the mechanical stability of foot piece, can occur damage phenomenons such as foot piece fractures behind the certain hour, has caused mechanical disorder, even has dangerous the generation.Tradition folding horizontal axis wind-driven generator can't overcome infiltration, stop sand and dust to corrode because reasons in structure can't seal fully, reduces class of safety protection greatly.Tradition folding horizontal axis wind-driven generator is in practical application, and tail vane axle and axle sleeve all can have wearing and tearing in various degree, have influenced the operation point of tail vane, and the important tail vane that also can make loses function, under the strong wind situation, burns generator, causes badly damaged.
Summary of the invention
The utility model overcomes the deficiency of existing technology, has proposed a kind of horizontal axis wind-driven generator revolution axis type empennage mechanism, and said empennage mechanism is a kind of brand-new working method tail structure, is applied in the horizontal axis wind-driven generator.As everyone knows, the working principle of empennage comes from aerodynamics, simply says; The impeller of wind-driven generator is in wind-engaging rotates, and the rear portion of impeller can form an eddy stress, and the tail plate pressurized can be according to the rotation automatically of pressure size; Reduce the impeller wind-exposuring area, the wind-force through impeller is reduced, wheel speed can reach rational rotating speed automatically; Keep impeller and generator to keep good rotating speed, guarantee that generator operation is at the high efficiency state.This kind empennage mechanism wind-driven generator is a revolution axis type tail vane wind-driven generator; The revolution axis type wind-driven generator can be realized sealing fully; The inner ripeness standard bearing that adopts, waterproof grommet is adopted in each parts connecting port, thoroughly realizes the sealing of sand and dust, water, salt fog is stoped.It is earth attraction that principle is adopted in the control of tail vane, factor affecting such as the control of operation point can be not in time, wearing and tearing.Be not easy to change the operation point, improved reliability greatly.During the real work of revolution axis type horizontal axis wind-driven generator, benefit from the unique technique innovation, movable parts only are that the transverse axis of tail vane rotates, and the work maximum angle is 90 °, basic friction.
The technological scheme of the utility model is: a kind of horizontal axis wind-driven generator revolution axis type empennage mechanism; Comprise fan blade, generator main body and horizontal rotating shaft formula tail vane; Horizontal rotating shaft formula tail vane is provided with a horizontal rotating shaft, and said fan blade is installed in the front portion of said generator main body, is provided with air guide sleeve in the front portion of fan blade; Be provided with revolution axis type empennage mechanism at the rear portion of generator main body, said revolution axis type empennage mechanism is connected with the generator main body with rear bearing through fore bearing.
The downside of the horizontal rotating shaft of horizontal rotating shaft formula tail vane is provided with a rudder plate.
The rudder plate of revolution axis type empennage mechanism is perpendicular to ground; The control generator correctly aligns wind direction under the normal condition, relies on the lever and the aerodynamic force of generator vertical shaft throw of eccentric during strong wind, drives the revolution axis type empennage and rotates along axis horizontal; The regulator generator rotating speed reaches the control purpose.
The utlity model has following beneficial effect
1) the utility model adopts the tail vane of revolution axis type, and is sensitive to the wind speed reacting condition, realizes the more reasonably control to the rotating speed of wind-driven generator.
