Abstract
The utility model discloses a wind power generation device, it includes base, generator and blade shaft, the base on be equipped with the generator, generator one end be connected with the driftage ware, blade shaft on be equipped with the stiffener, blade shaft and stiffener be connected with power generator shaft jointly, blade shaft on be equipped with a plurality of fan blade pieces, fan blade piece and blade shaft articulated, the fan blade piece back be equipped with the push rod, the push rod on the cover have a spring, spring one end and push rod fixed connection, the spring other end and stiffener fixed connection. The device simple structure, simple to operate can adapt to abominable strong wind environment, and wind energy utilization efficiency is high in addition, and not fragile, manufacturing cost can be sparingly over half, and the generating efficiency can improve more than the one time, and the security is high, and economic benefits is good.
Description
Technical field
This utility model relates to technical field of wind power generation, in particular, relates to a kind of wind power generation plant.
Background technology
Wind-power electricity generation is that the kinetic energy kept watch transfers electric energy to, wind energy is as the regenerative resource of a kind of cleaning, inexhaustible, nexhaustible, suitable in hydropenia, short bunker and ungetable offshore islands, Pastoral Areas, mountain area and area, plateau, utilize wind-power electricity generation treatment in accordance with local conditions, it is especially suitable for, it is well worth doing, the wind power generation plant used now, it is usually the wind wheel that shape is fixing, their air blade angle is unadjustable, the changeable atrocious weather environment such as island and area, plateau can not be well adapted to, particularly in when high wind is attacked, air blade is easily damaged by high wind, cause that wind wheel is scrapped, and existing wind wheel wind power utilization efficiency is low, cost is high, service life is shorter, deficiency in economic performance.
Utility model content
Technical problem to be solved in the utility model is in that to provide wind power generation plant, this apparatus structure is simple, easy for installation, it is adapted to severe harsher wind conditions, and wind energy utilization efficiency is high, is hardly damaged, manufacturing cost can save more than half, generating efficiency can be enhanced about more than once, and safety is high, good in economic efficiency.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of wind power generation plant, it includes pedestal, electromotor and blade shaft, described pedestal is provided with electromotor, described electromotor one end is connected to driftage device, described blade shaft is provided with bracing piece, described blade shaft and bracing piece are connected with alternator shaft jointly, described blade shaft is provided with some air blades, described air blade is hinged with blade shaft, the described air blade back side is provided with push rod, described push rod is cased with the fixing connection of spring, described spring one end and push rod, the described spring other end and the fixing connection of bracing piece.
Further, described air blade is positioned at blade shaft end.
Further, described push rod is 2～5
When wind-force is normal mild wind, air blade angle windward is about 60 degree, it is possible to efficiently utilize wind energy；When meeting with high wind, air blade angle windward is 0 degree, it is possible to effectively prevent TRT from damaging.
Prior art is compared, and the beneficial effects of the utility model are embodied in:
This utility model is by the push rod at the air blade back side and spring, it is achieved that adjust the effect at air blade angle windward flexibly so that air blade angle windward can change automatically with wind-force size, has both improve wind energy utilization, is possible to prevent again under high wind device and damages；Air blade is positioned at blade shaft end, can increase torque to greatest extent, improves wind energy utilization.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram；
Position view when Fig. 2 is this utility model installed part, air blade and blade shaft mild wind.
In figure: 1, pedestal；2, electromotor；3, driftage device；4, air blade；5, blade shaft；6, bracing piece；7, spring；8, push rod.
Detailed description of the invention
For the technological means making utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with being specifically illustrating, this utility model is expanded on further.
As depicted in figs. 1 and 2, a kind of wind power generation plant, it includes pedestal 1, electromotor 2 and blade shaft 5, pedestal 1 is provided with electromotor 2, electromotor 2 one end is connected to driftage device 3, blade shaft 5 is provided with bracing piece 6, blade shaft 5 and bracing piece 6 are connected with electromotor 2 rotating shaft jointly, blade shaft 5 is provided with some air blades 4, air blade 4 is hinged with blade shaft 5, air blade 4 back side is provided with two push rods 8, push rod 8 is cased with spring 7, spring 7 one end and the fixing connection of push rod 8, spring 7 other end and the fixing connection of bracing piece 6, in order to increase torque, air blade 4 is positioned at blade shaft 5 end.
Spring 7 and push rod 8 can control the angle of air blade 4, thus regulating the size at angle windward, when mild wind, it is possible to regulate angle windward and, about 60 degree floatings, improve wind energy utilization to greatest extent；When high wind, owing to wind-force is relatively big, spring 7 is by ultimate elongation, and angle is 0 degree windward, it is possible to prevent air blade 4 from being damaged by high wind, and driftage device 3 according to concrete environment wind direction, can change the direction of electromotor 2 and air blade 4, adapts to the wind energy of different angles.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
