Background technique
Wind energy resources has widely distributed, rich reserves, clean the advantages such as renewable, under the fossil energy such as coal and the oil international background that shortage, environment go from bad to worse increasingly, the exploitation of wind energy resources are day by day subject to the extensive concern of countries in the world and continue to drop into, and wind generating technology and industry worldwide obtain and develop faster.
In grid-connected large-scale wind generating technical field, apply most often horizontal axis blower fan at present in the world, its technology relative maturity, lots of production is large, has become the mainstream model of current blower fan.But along with the rising of distributed energy supply and blower fan miniature requirement, the shortcomings such as congenital deficiency such as horizontal axis fan starting wind speed is high, operating noise is large, wind loading rating is poor progressively expose, and have that structure is relatively simple, threshold wind velocity is low, aerodynamic noise is little, the better vertical shaft fan of wind-engaging performance, progressively steps into the visual field of people.
Vertical shaft fan is mainly divided into resistance force type vertical shaft wind machine and the large class of lift vertical shaft blower fan two.Resistance force type vertical shaft wind facility have the advantage that detent torque is large, threshold wind velocity is low, but pneumatic efficiency is lower; Although it is a little higher that lift vertical shaft blower fan has pneumatic efficiency, detent torque is little, threshold wind velocity is high, low wind speed region and urban applications comparatively difficult.If the advantages of two kinds of blower fans can be got up, design that to have threshold wind velocity concurrently low, the vertical shaft fan of the high two kinds of advantages of pneumatic efficiency obviously has the demand that more can adapt to distributed energy supply.
For realizing the purpose of design of above low speed start, Effec-tive Function, usual by lift vertical shaft blower fan wind wheel and resistance force type vertical shaft wind machine wind wheel stack combinations at present.Lift-type blade is in outer ring, and resistance type blade is in inner ring corresponding position, as described in patent (CN103527403A).Such design make use of the low advantage of resistance type blade threshold wind velocity on the one hand, and the larger starting torque utilizing resistance type blade to produce under gentle breeze drives wind wheel system to rotate, and reduces the threshold wind velocity of blower fan, achieves the purpose of design of low speed start; On the other hand, at higher wind speeds, when blower fan normally runs, lift-type blade is exerted oneself in the highest flight.Now, the resistance type blade being in inner ring is little by air-flow direct effect, mainly rotates under lift-type blade drives.While bringing added power dissipation, the original air flow method in whole flow field has been confused in the rotation of resistance type blade, causes lift-type blade pressure surface air pressure to decline.And the change of lift-type blade stream field is comparatively responsive, the change of flow field and pressure brings the decline of pneumatic efficiency, causes whole wind wheel system to utilize the decline of wind energy efficiency.In addition, in patent (CN103527403A), the design of two panels resistance type blade can not ensure to eliminate dead point when starting completely.If wind is from just blowing resistance type blade side direction, just little to the blade area of incoming flow, need very large wind speed, blower fan could start or can not start completely.
If by rational design, when making low wind speed, vane extension is resistance type blade, to obtain lower threshold wind velocity; During high wind speed, autocondensation becomes lift-type blade, is lift-type blower fan when being resistance type blower fan, high speed during low speed.In addition the double H-type wind wheel layout in lift-type blower fan, if by rational pneumatic design, system can obtain the pneumatic efficiency more more excellent than common H type lifting wind wheel.Increase blade number simultaneously, eliminate the existence at dead point when starting.To realize low speed start, Effec-tive Function, without the purpose of design starting dead point, this programme is and solves problems and design.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Embodiment 1
As shown in Figures 1 to 6, for low speed start of the present invention rises resistance change formula blade vertical shaft fan wind wheel system.Wind wheel system is made up of main shaft 1, changable type blade 3, connecting rod 4, as shown in Figure 1.
In the present invention, the hollow blade that all blades all select light anticorrosive material (comprising unsaturated resin, saturated resin, carbon fiber, light aluminum alloy etc.) to manufacture, there is the advantage such as corrosion resistance and good, quality is light, intensity is high, excellent heat insulating performance, easily processing, adopt very thin thickness can meet design strength requirement, to alleviate wind wheel quality.Changable type blade 3 adopts hollow H type vane foil, near pressure side outer surface distance trailing edge about 2/to three/3rds place and the trailing edge place of main shaft 1 one side, vertically, be split into first point of blade face 3-1 and shorter second point blade face 3-2,3-1 pressure side side, first point of blade face separating surface arranged fixed rotating shaft 7 in order to connect first point of blade face and second point of blade face.Torsion spring 9 is provided with between first point of blade face 3-1 and second point of blade face 3-2, on the internal surface that torsion spring 9 is packed in first point of blade face 3-1 or second point of blade face 3-2 near fixed rotating shaft 7 or be sleeved on fixed rotating shaft 7, in figure, only give a kind of form on the internal surface being packed in first point of blade face 3-1 in 3,4.Second point of blade face 3-2 is provided with pouring weight 8 away from one end of fixed rotating shaft 7, and pouring weight 8 and torsion spring 9 acting in conjunction, in order to control the opening and closing of second point of blade face 3-2.The bipod of torsion spring 9 connects on first point of blade face 3-1 and second point of blade face 3-2 nearly trailing edge end internal surface respectively, and on the bipod of torsion spring 9, cover is connected to " ∞ " type metal collar, in order to control the angle that second point of blade face 3-2 opens, as shown in Figure 5.Changable type blade 3 blade profile becomes along with wind speed and wind wheel system rotating speed, and when rotating speed is lower, second point of blade face 3-2 opens centered by fixed rotating shaft 7, in resistance type blade state, as shown in Figure 4.When rotating speed is higher, second point of blade face 3-2 closes under the influence of centrifugal force, and now changable type blade 3 becomes lift-type blade state, as shown in Figure 3.
When blower fan is static or wind speed is less, wind speed round is less, for wherein a slice changable type blade 3, the centrifugal force that pouring weight 8 shown in Fig. 4 produces is less, and be not enough to the elastic force that counteracting torsion spring 9 produces, second point of blade face 3-2 outwards opens centered by fixed rotating shaft 7.Changable type blade 3 is now resistance blade, presents resistive state.Simultaneously, be sleeved on and torsion spring 9 bipod presents the connected metal collar of two of " ∞ " type, the angle of being opened by restriction torsion spring 9 bipod is to limit second point of blade face 3-2 subtended angle, and the lower second point of blade face 3-2 of offset resistance state, by incoming flow drag effect, makes the trend that subtended angle increases.When taking full advantage of low wind speed, resistance type blade rotation moment is large, the advantage that threshold wind velocity is low.
When wind speed increases gradually, when the rotating speed of blower fan rises gradually, the centrifugal force that pouring weight 8 produces increases gradually, when its size exceedes the elastic force that torsion spring 9 produces, second point of blade face 3-2 inwardly closes gradually centered by fixed rotating shaft 7, final closing completely becomes lift-type blade, presents lift conditions, to utilize the efficiency that lift-type blade is higher.
The another kind of form of changable type blade as shown in Figure 8, changable type blade 3 is still made up of first point of blade face 3-1 and shorter second point blade face 3-2, both are connected by fixed rotating shaft 7, and difference is that second point of blade face 3-2 is connected one end and stretches out in the shorter segment length of rotating shaft 7 with rotating shaft 7.Second point of page 3-2 nearly trailing edge one end internal surface is equipped with magnet 10, and the other end internal surface is equipped with the 3rd magnetic stripe 13; The first magnetic stripe 11 is equipped with in first point of nearly trailing edge one end of blade face 3-1, and nearly 3rd magnetic stripe 13 place internal surface is equipped with the second magnetic stripe 12.First magnetic stripe 11, second magnetic stripe 12, the 3rd magnetic stripe 13 weight are all lighter than magnet 10.Magnet 10 and the first magnetic stripe 11 apparent surface, the second magnetic stripe 12 and the 3rd magnetic stripe 13 apparent surface are homopolarity magnetic face.When blower fan is static or wind speed is less, wind speed round is less, for wherein a slice changable type lift-type blade 3, magnet 10, with the effect providing centrifugal force, can carry corresponding counterweight as required.The centrifugal force that magnet 10 provides is less, is not enough to offset the magnetic repulsion force between magnet 10 and the first magnetic stripe 11, second point of blade face 3-2 opened with certain angle centered by fixed rotating shaft 7 under the effect of magnetic repulsion force.When wind comes, by the drag effect of incoming flow, second point of blade face 3-2 continues outwards to open, 3rd magnetic stripe 13 of the other end and the second magnetic stripe 12 more and more close, magnetic repulsion force is increasing, until connecting part, two sides, in order to limit the angle that second point of blade face 3-2 opens.Now wind wheel not yet rotate or the centrifugal force that provides with the magnet 10 that slowly runs less.When wind speed increases gradually, when the rotating speed of blower fan rises gradually, the centrifugal force that magnet 10 produces increases gradually, when its size is enough to offset magnetic repulsion force, second point of blade face 3-2 inwardly closes gradually centered by fixed rotating shaft 7, finally closes completely and becomes lift-type blade.It should be noted that magnet 10 and the first magnetic stripe 11 will have suitable distance apart from trailing edge, to utilize the gap of blade hollow structure, reserve certain spacing to both, prevent too close, magnetic repulsion force is too large, causes in wind speed range that blade cannot be suitable again closed.
