Description
Technical field
This utility model relates to wind-driven generator field, particularly relates to the wind-driven generator of a kind of feather without electric-controlled mechanical.
Background technology
The commonly used hydraulic variable-pitch of feather of existing wind-driven generator or motor independent pitch away from, hydraulic variable-pitch is owing to using hydraulic oil as the medium of transmission power, so whole system response speed adapts to ability slowly, in the environment that temperature is low, hydraulic oil is the most frozen and makes described hydraulic variable-pitch device paralyse, if started by force, the big motor of wind-force has destroyed risk.The feather of each blade making wind-driven generator that motor independent pitch refers to away from device is driven corresponding reduction box by an independent motor, due to motor and the manufacturing variation of reduction box itself, during feather, it is ensured that it is unanimously extremely difficult that the propeller pitch angle of each blade keeps.
Utility model content
The utility model proposes the wind-driven generator of a kind of feather without electric-controlled mechanical, solve prior art wind electromotor feather and cannot ensure that the pitch of multiple blade adjusts consistent problem.
The technical solution of the utility model is achieved in that the wind-driven generator of a kind of feather without electric-controlled mechanical, including:
Circular hub, the center of described wheel hub is provided with main shaft, and the top of described main shaft is fixedly connected with nut；
Three bearing bases, are distributed on described wheel hub；
Three petiole rotary shafts, are fixed on described bearing base；
Three gears, described gear is fixing with the tail end of described petiole rotary shaft to be connected；
Be meshed rack circle sliding sleeve with described gear, is socketed on described main shaft；
It is provided with spring between described rack circle sliding sleeve and described nut.
As preferred technical scheme, described main shaft is provided with is easy to the sliding ball that described rack circle sliding sleeve slides up and down.
As preferred technical scheme, also including the fastening cap being positioned at described nut top, described fastening cap is fixed on described main shaft.
As preferred technical scheme, described petiole rotary shaft is fixed on described bearing base by the way of welding.
As preferred technical scheme, described spring housing is connected on described main shaft.
This utility model is produced beneficial effect compared with background technology:
nullThe main shaft of wheel hub is socketed rack circle sliding sleeve respectively、Spring，When the blast that blade is subject to is increasing，The pinion rotation of paddle belt movable vane handle rotary shaft tail end，The rack circle sliding sleeve being meshed with gear moves upward，The spring stress at rack circle sliding sleeve top the most upwards compresses，The angle that the biggest blade of blast rotates is the biggest，Unnecessary wind-force is thus made to shed，Maintain wind-driven generator normal rotation and electromotor main frame is not burned out，When blade is by maximum wind pressure，Blade rotation turnback，Rack circle sliding sleeve rises to top，Gapping of spring closes，So blade reforms into resistance and ensure that the safety of complete machine，Owing to the addition of rack circle sliding sleeve and spring，Ensure that the concordance that each blade moves，This utility model simple in construction，Durable in use，It is not afraid of thunderstorm weather，Without automatically controlled performance，Can the most automatically adjust blast，Easy-maintaining，Cost is low.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1 and Figure 2, the wind-driven generator of a kind of feather without electric-controlled mechanical, including, circular hub 1, the center of wheel hub 1 is provided with main shaft 7, and the top of main shaft 7 is fixedly connected with nut 8；Three bearing bases 4, are distributed on wheel hub 1, and three bearing bases 4 are bolted on wheel hub 1；Three petiole rotary shafts 3, are fixed on the upper of bearing base 4, and concrete petiole rotary shaft 3 is fixed on bearing base 4 by the way of welding；Three gears 5, gear 5 is fixing with the tail end of petiole rotary shaft 3 to be connected, and the leading section of three petiole rotary shafts 3 has been fixedly connected with flange 6, and blade is connected by bolt is fixing with flange 6；Be meshed rack circle sliding sleeve 2 with gear 5, is socketed on main shaft 7；Spring 11 it is provided with between rack circle sliding sleeve 2 and nut 8, spring 11 is socketed on main shaft 7, main shaft 7 is provided with is easy to the sliding ball 10 that rack circle sliding sleeve 2 slides up and down, also include the fastening cap 9 being positioned at nut 8 top, fastening cap 9 is fixed on main shaft 7, sliding 2 sets of 9 nuts 8 of fastening cap, spring 11, rack circle are fixed on main shaft 7 firmly, and nut 8 of the present utility model is used for regulating spring 11 compressive deformation.
Feather work process: set wind-driven generator rated wind speed as 9m/s, under this wind speed, wind-driven generator runs well, when running into greater pressure, the gear 5 of paddle belt movable vane handle rotary shaft 3 tail end rotates, the rack circle sliding sleeve 2 being meshed with gear 5 moves upward, spring 11 stress at rack circle sliding sleeve 2 top is the most upwards compressed, blade also sheds part blast during rotating, when blade is by maximum wind pressure, blade rotation turnback, rack circle sliding sleeve 2 rises to top, spring 11 gap-closing, so blade reforms into resistance and ensure that the safety of complete machine, when spring 11 flicks, rack circle sliding sleeve 2 glides, blade enters normal condition.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
