Description
Technical field
The present invention relates to a kind of wind-driven generator, and in particular to a kind of wind-driven generator tail gear.
Background technology
Traditional small-sized horizontal shaft wind-driven（Protected using empennage）, need to roll over tail or driftage by empennage when wind speed is higher to reduce the rotating speed of wind-driven generator, play a part of to adjust and protect wind-driven generator.Common empennage operative orientation is left and right folding tail protection; when wind speed is higher; influenceed by foot piece length and fin area and foot piece angle; phenomenon slow in reacting occurs; the slow phenomenon of return can be produced after folding tail protection generator speed reduction again; the efficiency that Similar Problems directly result in wind-driven generator is substantially reduced, it is impossible to realize value maximization of the wind-driven generator to Wind Power Utilization.Meanwhile, the action of the folding tail of foot piece long-term continuity certainly will greatly reduce the mechanical stability of foot piece, occur that foot piece fractures after certain hour and wait damage phenomenon, cause mechanical disorder, or even have dangerous generation.Traditional folding-tail type horizontal axis wind-driven generator is because reasons in structure, it is impossible to be fully sealed, it is impossible to overcomes infiltration, prevent sand and dust from corroding, substantially reduces class of safety protection.In actual applications, tail vane axle and axle sleeve can all have different degrees of abrasion to traditional folding-tail type horizontal axis wind-driven generator, have impact on the operating point of tail vane, and the important tail vane that can also make loses function, generator is burnt under high wind conditions, causes badly damaged.
The content of the invention
The present invention overcomes the deficiencies in the prior art, it is proposed that a kind of wind-driven generator tail gear, and the empennage mechanism is a kind of brand-new working method tail structure, is applied in horizontal axis wind-driven generator.It is known that, the operation principle of empennage comes from aerodynamics, simply say, in wind-engaging is rotated, the rear portion of impeller can form an eddy stress to the impeller of wind-driven generator, tail plate is pressurized can automatically be rotated according to pressure size, impeller front face area is reduced, makes to be reduced by the wind-force of impeller, wheel speed can automatically achieve rational rotating speed, impeller and generator is kept to maintain good rotating speed, it is ensured that generator operation is in high efficiency state.This kind of empennage mechanism wind-driven generator is rotary shaft tail vane wind-driven generator, rotary shaft wind-driven generator can be realized being fully sealed, inside uses ripeness standard bearing, and each part connectivity port uses waterproof grommet, thoroughly realizes preventing the sealing of sand and dust, water, salt fog.It is terrestrial gravitation that the controlling of tail vane uses principle, and the control of operating point will not influence with factors such as time, abrasions.Do not allow malleable operating point, substantially increase reliability.During rotary shaft horizontal axis wind-driven generator real work, the technological innovation of uniqueness is benefited from, the part of activity is only the transverse axis rotation of tail vane, and work maximum angle is 90 °, substantially without friction.
The technical scheme is that：A kind of wind-driven generator tail gear, including fan blade, generator main body and tail vane, the fan blade is arranged on the front portion of the generator main body, kuppe is provided with the front portion of fan blade, rotating shaft mechanism is provided with the rear portion of generator main body, the front end of the rotating shaft mechanism is connected by a front roll bearing with generator main body phase, and the rear end of the rotating shaft mechanism is connected by a rear rolling bearing with the tail vane.
Revolving body is provided with the bottom of generator main body.
Hood is provided with the outside of rotating shaft mechanism.
The present invention has the advantages that
1）The present invention is sensitive to wind speed reacting condition using the tail vane using rotary shaft, realizes the more rational control to the rotating speed of wind-driven generator.
2）Tail plate of the present invention, rationally using tail shape, coordinates the work of rotary shaft tail vane more accurate according to bionics.
3）Slew gear of the present invention uses integral type extrusion process, it is ensured that the precision of vertical shaft and tail plate simultaneously ensures closely connection, prevents the generation of failure.
4）Instant invention overcomes traditional folding-tail type tail vane weakness high to the requirement of pylon setting angle, this structure adapts to boat-carrying and high wind speed area is installed to pylon setting angle no requirement (NR).
5）The present invention is capable of achieving to be fully sealed, and inside uses ripeness standard bearing, and each part connectivity port uses waterproof grommet, thoroughly realizes preventing the sealing of sand and dust, water, salt fog.It is terrestrial gravitation that the controlling of tail vane uses principle, and the control of operating point will not influence with factors such as time, abrasions.Good sealing effect, without friction, stabilization of operating point, substantially increase reliability.During rotary shaft horizontal axis wind-driven generator real work, the technological innovation of uniqueness is benefited from, the part of activity is only the transverse axis rotation of tail vane, and work maximum angle is 90 °, substantially without friction.

Specific embodiment
Refering to shown in Fig. 1 to Fig. 2, the present invention includes fan blade 2, generator main body 3 and tail vane 8, the fan blade 2 is arranged on the front portion of the generator main body 3, kuppe 1 is provided with the front portion of fan blade 2, kuppe 1 can preferably absorb and control wind regime, rotating shaft mechanism 7 is provided with the rear portion of generator main body 3, revolving body 9 is provided with the bottom of generator main body 3, generator main body 3 can be rotated around revolving body 9.The front end of the rotating shaft mechanism 7 is connected by a front roll bearing 4 with generator main body 3, and the rear end of the rotating shaft mechanism 7 is connected by a rear rolling bearing 6 with the tail vane 8, and the axis mechanism 7 that can rotate of tail vane 8 is rotated.Rotary shaft rack 10 is provided with the bottom of rotating shaft mechanism 7, hood 5 is provided with the outside of rotating shaft mechanism 7.Operation principle is：
According to aerodynamic principle, when the fan blade 2 of wind-driven generator is rotated under wind-force effect, the rear portion of impeller 2 can form an eddy stress, after tail vane 8 is pressurized, can automatically be rotated according to pressure size, so as to reduce the front face area of fan blade 2, make to be reduced by the wind-force of fan blade 2, the rotating speed of fan blade 2 can automatically achieve Rational Rotation Speed, keep fan blade 2 and generator to maintain good rotating speed, it is ensured that generator operation is in high efficiency state.Instant invention overcomes traditional folding-tail type tail vane weakness high to the requirement of pylon setting angle, this structure adapts to boat-carrying and high wind speed area is installed to pylon setting angle no requirement (NR).
