Abstract
The utility model discloses wind-powered electricity generation flabellum, comprise install successively blade tip, stage casing and rear; Described rear and impeller Flange joint; Also comprise reducing gear; Described reducing gear comprises outer cover, hydraulic mechanism, active friction head and passive friction head; Described outer cover is installed bottom rear; Described outer cover is provided with friction mouth near rear side; Described hydraulic mechanism is installed on friction mouth place; Described active friction head is installed on front side of hydraulic mechanism, and movable embedding friction mouth; Described passive friction head is fixed on rear rear portion, becomes a up-down structure with active friction capitiform.Wind-powered electricity generation flabellum of the present utility model, when blade High Rotation Speed, enables unit normally work, and when rotational speed exceedes certain value, can protect break and the step-up gear of inner side.
Description
Technical field
The utility model relates to wind-powered electricity generation flabellum, belongs to electrification component technical field.
Background technique
Wind power technology equipment is the important component part of Wind Power Generation Industry, also be basis and the guarantee of Wind Power Generation Industry development, wind power generating set realizes the equipment that Wind resource change becomes electric energy, generally includes wind turbine, driving mechanism, generator, automatic controller and support steel tower etc.; The effect of wind turbine is mechanical energy by Wind resource change, and it is contained on wheel hub by 2 ~ 3 blades of aeroperformance excellence and forms, the wind wheel slowly run by transmission system by step-up gear speedup, by transmission of power to generator; Existing wind power generating set usually can arrange break inside its unit; work when conveniently can overhaul and avoid wind scale excessive; break is generally installed on front side of step-up gear and rear side; be generally mechanical brake; but because break limits quitting work of rotating shaft inside unit; the blade in outside still can work as usual, makes the rotating shaft of step-up gear bear very large pressure, easily damages break and step-up gear.
Summary of the invention
(1) technical problem that will solve
For solving the problem, the utility model proposes wind-powered electricity generation flabellum; When inboard brake, also can brake in outside, or reduce the high speed rotating of blade.
(2) technological scheme
Wind-powered electricity generation flabellum of the present utility model, comprise install successively blade tip, stage casing and rear; Described rear and impeller Flange joint; Also comprise reducing gear; Described reducing gear comprises outer cover, hydraulic mechanism, active friction head and passive friction head; Described outer cover is installed bottom rear; Described outer cover is provided with friction mouth near rear side; Described hydraulic mechanism is installed on friction mouth place; Described active friction head is installed on front side of hydraulic mechanism, and movable embedding friction mouth; Described passive friction head is fixed on rear rear portion, becomes a up-down structure with active friction capitiform.
Further, described active friction head and passive friction head are made by rubber material.
Further, described hydraulic mechanism is hydraulically extensible bar; Its installation parallel with rear.
Further, described reducing gear is arranged at the afterbody place of every sheet flabellum respectively.
(3) beneficial effect
Compared with prior art, wind-powered electricity generation flabellum of the present utility model, controls the friction of active friction head and passive friction head by hydraulic mechanism; When blade High Rotation Speed, its rotational speed can be reduced by active friction head and passive friction head, unit is normally worked, when rotational speed exceedes certain value, directly by internal detent, unit internal work is stopped, outside active friction head reduces fan blade speed, reduces the high speed rotating of blade; The break of protection inner side and step-up gear.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Embodiment
Wind-powered electricity generation flabellum as shown in Figure 1, comprise install successively blade tip 1, stage casing 2 and rear 3; Described rear 3 and impeller Flange joint; Also comprise reducing gear; Described reducing gear comprises outer cover 4, hydraulic mechanism 5, active friction head 6 and passive friction head 7; Described outer cover 4 is installed bottom rear; Described outer cover 4 is provided with friction mouth 8 near rear side; Described hydraulic mechanism 5 is installed on friction mouth 8 place; Described active friction head 6 is installed on front side of hydraulic mechanism 5, and movable embedding friction mouth 8; Described passive friction head 7 is fixed on rear 3 rear portion, forms a up-down structure with active friction head 6.
Wherein, described active friction head 6 and passive friction head 7 are made by rubber material; Described hydraulic mechanism 5 is hydraulically extensible bar; Its installation parallel with rear 3; Described reducing gear is arranged at the afterbody place of every sheet flabellum respectively.
Wind-powered electricity generation flabellum of the present utility model, controls the friction of active friction head and passive friction head by hydraulic mechanism; When blade High Rotation Speed, its rotational speed can be reduced by active friction head and passive friction head, unit is normally worked, when rotational speed exceedes certain value, directly by internal detent, unit internal work is stopped, outside active friction head reduces fan blade speed, reduces the high speed rotating of blade; The break of protection inner side and step-up gear.
Embodiment recited above is described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that related domain ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
