Description
Technical field
The utility model is related to the wind blade group of wind-driven generator, more particularly to a kind of combined vertical axis wind power generation
Machine.
Background technology
Wind energy is contained in each corner of land and ocean extensively, and its is sustainable, green, pollution-free, the advantages of easily obtain
Fall over each other the hot point resource of exploitation as everybody.THE WIND ENERGY RESOURCES IN CHINA is very abundant, about 2.5 hundred million kilowatts of developable installed capacity, occupies
First place in the world, but our the actual wind-power electricity generation installed capacitys of country only account for the 0.11% of national electric power installation, wind-power electricity generation development
Have a high potential.
Existing utilization wind-driven generator mainly includes two major classes：Trunnion axis and vertical axis aerogenerator.At present both at home and abroad
In the market, horizontal axis wind-driven generator or dominant form.But, horizontal shaft type wind-driven generator has very big weak point.
Such as：Horizontal shaft type wind-driven generator setting height(from bottom) is high, space-consuming is big, it is necessary to yaw system windward, wind loading rating is poor, fortune
Noise is big during row, and starting wind velocity is higher, typically requires more than 3.5m/s.Compared with horizontal shaft type wind-driven generator, vertical shaft wind
Power generator is adapted to any wind direction, and setting height(from bottom) is low, can disjunctor arrangement, occupy little space；Noise is small during operation, starts wind
Speed is low.Therefore vertical axis aerogenerator is more and more paid attention in recent years.
Vertical axis aerogenerator is broadly divided into resistance-type and lift-type.Resistance type vertical shaft wind driven generator is mainly profit
With air flow through blade produce resistance as driving force, threshold wind velocity is relatively low；And lift-type is then to flow through leaf using air
The lift that piece is produced is as driving force, and threshold wind velocity is higher.Because blade is in rotary course, with the increase resistance of rotating speed
Strongly reduce, and lift can increase on the contrary, so the efficiency of the vertical axis aerogenerator of lift-type wants the high very of specific resistance type
It is many.
Existing vertical axis aerogenerator patent application present situation is taken a broad view of, is to use single resistance-type or lift-type mostly
Blade, such as patent CN104088754, CN204738907U, generally existing wind energy utilization is not good and can not take into account generating effect
The problem of rate is low, threshold wind velocity is low.Small part is in order to which the big shortcoming of threshold wind velocity needed for overcoming lift-type blade is in upper and lower side
Add resistance-type blade (or starting vane) collocation to use, such as patent CN106121910A, CN104131952A, to strengthen wind speed
Adaptability when smaller.But, upper and lower side substantially increases wind-force hair plus resistance-type blade and relevant connection, removing mechanism
Electric end weight, adds the burden of lower end angular contact ball bearing, friction torque increase, and generating efficiency and threshold wind velocity are all difficult
To effective improvement.
The content of the invention
To solve the deficiencies in the prior art, there is provided a kind of combination type vertical axis wind power generation plant, this wind-power electricity generation dress
Put, rational in infrastructure, generating efficiency is high.
To achieve the above object, the utility model uses following technical scheme：
A kind of combined wind power generating set with vertical shaft, including central rotating shaft, are provided with angular contact ball below central rotating shaft
Bearing, at least two groups combined blades are fixedly connected by connecting rod with central rotating shaft, and every group of combined blade includes at least two
The combined blade of piece, every combined blade includes a piece of hollow cuboid straight panel and a piece of hollow curved surface streamline template, curved surface
Streamline template includes positive plate and backboard, and positive plate is the curved surface streamline template away from central rotating shaft, and backboard is close to central rotating shaft
Curved surface streamline template, curved surface streamline template is fixedly connected with the side of hollow straight panel.
A kind of above-mentioned combined wind power generating set with vertical shaft, curved surface streamline template and the space angle of hollow straight panel exist
Between 90 ° -180 °.
The height ratio of a kind of above-mentioned combined wind power generating set with vertical shaft, cuboid straight panel and curved surface streamline template is
1:1—1:1.5, width ratio is：0.5：1-1:1.
The surface curvature of a kind of above-mentioned combined wind power generating set with vertical shaft, the positive plate of curved surface streamline vane and backboard
Difference, backboard curvature is more than positive plate curvature.
A kind of above-mentioned combined wind power generating set with vertical shaft, every group of combined blade is contour to be equally spaced.
A kind of above-mentioned combined wind power generating set with vertical shaft, every group of combined blade is from the nearlyer height of central rotating shaft more
It is high.
A kind of above-mentioned combination-type vertical axis wind generator, the every group of distance of combined blade away from central rotating shaft.
Curved surface streamline template include positive plate and backboard, positive plate be away from central rotating shaft curved surface streamline template, backboard be by
The curved surface streamline template of nearly central rotating shaft, it is middle after positive plate and backboard both sides connection to form hollow curved surface streamline template.
Vertical axis aerogenerator is in operation process, and the bearing of blade bottom connection generator will bear axial weight simultaneously
Power and radial beat power.Also integrity problem is taken into account when therefore, from bearing.Footpath can be born simultaneously from angular contact ball bearing
To load and axial load, it can work at higher rotational speeds.Other bearings are performed poor under two kinds of load effects, as ball connects
Contact bearing, which can only bear axial load, can not bear radial load；Deep groove ball bearing substantial radial load, axial load compared with
It is easy to destruction etc. when big.
Cuboid straight panel is resistance-type blade, and curved surface streamline template is lift-type blade；Resistance-type blade, which has, stops wind
Power obtains rotating torque, the characteristics of threshold wind velocity is small, and lift-type blade used in the utility model just, two face curvatures of the back of the body it is different,
Back surface curvature is bigger, and front face area is big in rotary course, lift is big.The utility model makes resistance-type and the combination of lift-type blade
With making the utility model possess the characteristics of threshold wind velocity is low, generating efficiency is efficient.
Blade used in the utility model is all hollow-core construction, dramatically reduces leaf weight, reduces angular contact ball axle
The load and friction power loss born.Also, under low when high during wind speed, unstable many variable working condition, the inclined square of angular contact ball bearing
It is reduced, enhances service life and reliability.Multiple blade rowses, which are stacked, can make full use of wind energy.
The utility model solves that prior art low wind speeds generating efficiency is low, wind energy utilization is not enough, and generator low speed is opened
The problem of dynamic performance is not good.
