Abstract
The utility model provides a wind power generating machine with vertical spindle, vertical vane and a plurality of blades, which belongs to wind power generation technical field and mainly comprises a vertical spindle. The vertical spindle is provided with a transverse bearing, a drive plate and a vertical vane assembly and is arranged on a liquid bearing, wherein the drive plate is connected with a variable speed generator via a drive gear. Owning to the adoption of mutual fit among the vertical spindle, the vertical vane, the plurality of blades and the liquid bearing, the utility model does not need an air resisting device but provides power via the air regulation difference among the vertical spindle, the vertical vane and the plurality of blades, can absorb the wind pressure from all directions, has low requirements on working wind speed and has large application scope; because the liquid bearing is adopted, the working friction coefficient of the wind power machine is small and the start wind speed is reduced; the generator and a gear box are mounted on the ground, are simple in structure, lower in cost and convenient to maintain, which are beneficial for designing megawatt big power wind power generator set.
Description
Technical field
The utility model relates to a kind of vertical axis windmill, especially a kind of perpendicular wing multiple-blade wind energy conversion system of vertical shaft that adopts the composite structure of perpendicular wing multiple-blade of vertical shaft and liquid-bearing load-bearing.
Background technique
Present common wind power station, great majority are to use " horizontal-shaft wind turbine ", and horizontal-shaft wind turbine is meant the mounting point of wind cabin axis and the wind energy conversion system of level.What generally use now is the grid type horizontal-shaft wind turbine, deficiency is: " horizontal-shaft wind turbine " cabin is installed on the pylon up to 20m-50m, the blade swing diameter of large-scale propeller type wind energy conversion system has more than 40 meters, and wind energy has the wind speed of the value utilized usually all more than 10 meter per seconds, weigh hundreds of kilogram even more than a ton of individual blade, blade will be subjected to huge action of centrifugal force, and the stress model of the blade of propeller type wind energy conversion system is a cantilever beam structure, the internal force situation is relatively poor, and therefore the material for blade has very harsh requirement.Need to adopt carbon fiber-reinforced resin and make blade in very strict condition, cost is very high, causes the construction cost height in whole power station, and cabin and blade are safeguarded very inconvenient, and it is big to make installation difficulty.Blade still is a kind of rapid wear product, and the replacing of blade has also been caused the raising of cost of electricity-generating, and these have all limited the popularization and application of propeller type wind energy conversion system, and the unit electric motor power that enlarges the propeller type wind energy conversion system again is unusual difficulty.Another kind of " vertical axis windmill " is meant the mounting point wind energy conversion system vertical with horizontal plane of wind cabin axis.Existing vertical axis windmill, its major defect is: wind wheel is installed in the smaller place of wind-force on close relatively ground, and efficient is lower.
Summary of the invention
The purpose of this utility model be to provide a kind of can be according to the angle of facining the wind of the automatic adjusting vane of wind direction, high working efficiency, construction, maintenance and cost of electricity-generating are low, can be under low wind speed the perpendicular wing multiple-blade wind energy conversion system of the normal vertical shaft that starts.
The purpose of this utility model is achieved in that a kind of vertical shaft erects wing multiple-blade wind energy conversion system, comprise vertical shaft 1, vertical shaft 1 is provided with horizontal bearing 2, drive plate 3 is housed on the vertical shaft 1, drive plate 3 is connected with variable-speed generator 5 by driving gear 4, it is characterized in that: vertical shaft 1 is installed on the liquid-bearing 11, perpendicular wing assembly 8 is installed on the vertical shaft 1, perpendicular wing assembly 8 comprises and is installed in a plurality of perpendicular winged petiole sheets 6 between two crossbeams 15, perpendicular winged petiole sheet 6 is connected with crossbeam 15 by vanes fixed bearing 9, positioning rod 11 is housed on the crossbeam 15, and positioning rod 11 is by connecting slip rod member 12, connecting rod 13 and blade sliding bearing 7 are connected with perpendicular winged petiole sheet 6.Three perpendicular wing assemblies 8 are housed on the vertical shaft 1, and formed angle is 120 degree between each perpendicular wing assembly 8.
Vertical shaft provided by the utility model erects wing multiple-blade wind energy conversion system, because the structure that has adopted the perpendicular wing multiple-blade of vertical shaft to match with liquid-bearing, do not need wind apparatus, provide power by the perpendicular mutliblade adjusting wind of the wing difference of vertical shaft, can absorb wind-force from any direction, can between wind speed 0.6m/s-1m/s, just can start generating, to work wind speed require lowly, application domain enlarges; Liquid-bearing uses, and wind energy conversion system work friction factor is little, reduced the startup wind speed; Generator and gearbox are all installed on the ground, and be simple in structure, cost is low and be convenient to safeguard, helps designing the megawatt-grade high-power wind power generating set.

Embodiment
The utility model adopts following structure: a kind of vertical shaft erects wing multiple-blade wind energy conversion system, and it mainly is made up of three perpendicular wing assemblies 8, perpendicular winged petiole sheet 6, liquid-bearing 10, variable-speed generator 5.Formed angle is 120 degree between each perpendicular wing assembly 8, perpendicular wing assembly 8 is installed on the vertical shaft 1, described perpendicular wing assembly 8 mainly comprises, four perpendicular winged petiole sheets 6 erect winged petiole sheet movable supporting point with vanes fixed bearing 9 conducts that are arranged on the blade two ends, and blade live bearing 7 has guaranteed that by connecting rod 13, connection slider 12 and positioning rod 11 perpendicular winged petiole sheet utilizes wind direction adjusting operating angle.
Working principle of the present utility model is: three perpendicular wing assemblies 8 are installed on vertical shaft 1, are spent at a distance of 120 between 8-1.8-2.8-3, each perpendicular wing assembly installation position.With 12 hours was the time scale orientation for example: the north wind opposite blows, and the perpendicular wing assembly of 8-1 is in 3 o'clock orientation, perpendicular winged petiole sheet comprehensively with the wind state be | | | shape.This moment the air resistance coefficient minimum.8-2 is in 11 o'clock orientation, and perpendicular winged petiole sheet 6 is at opposite direction wind-engaging state, and perpendicular winged petiole sheet Close All is close to perpendicular wing crossbeam, air resistance coefficient maximum at this moment.8-3 is in 7 o'clock orientation, and the same 8-2 of working state is referring to shining Fig. 3; From top working method as can be seen, the work energy is from the thrust of 8-2 and 8-3 blade face wind-engaging, and system's wind-engaging difference is big, guarantees to start easily.Vertical shaft erects wing multiple-blade wind energy conversion system, and generator adopts many gearbox generator integrated machines 5, adopts many series connection to use.According to wind speed decision working quantity, guarantee output voltage stability.Liquid-bearing adopts " water " to make load-bearing liquid, and is not only free from environmental pollution, can also be used for unnecessary electricity water lift, is used for field irrigation, the people, animal potable water is preserved.Dish formula braking 14 is when preventing that running from overrunning and uses during maintenance service, guaranteed the power generation system proper functioning.
