Technical field
The invention belongs to wind-power electricity generation and Material Field, and in particular to a kind of light-duty wind power generation plant.
Background technology
Current wind power generating set is mainly disposed to western tuyere position or sea, and it is required extremely blade material
Height, and also very high to the requirement of the contacts such as bearing, this be due to many speed-limiting device without wind-force of existing Wind turbines,
That is when wind-force is very big, the long-term rotational speed high of wind electricity blade, the abrasion to contacts such as bearings.Even if having
The device of wind-force speed limit is also the purpose that speed limit is reached by the reduction of speed to rotary shaft, and a lot of other consumable accessorys are increased on foot.
The wind-driven generator of arc wind blade also has some to study at present, and ice fan is referred to as in the industry, is characterized in non-
Chang Rongyi is minimized, and wind resource utilization rate is higher, but because the relatively conventional wind blade of its rotating speed is many soon, it is to rapid wear
The destructive power of part is very big, therefore how to carry out the content that reduction of speed is paid close attention to as needs to it when wind-force is big, such as
Fruit not can solve the problem of reasonable reduction of speed, then can seriously hinder the development of the wind-driven generator of arc wind blade.
The content of the invention
The present invention is by proposing a kind of light-duty wind power generation plant.
Realized especially by following technological means：
A kind of light-duty wind power generation plant, the light-duty wind power generation plant includes frame structure, moving blade device and generating
Unit.
The frame structure includes the rotating bar that is vertically arranged, rotating bar top and lower end be respectively arranged with upper bearing (metal) and
Lower bearing, the fixed mount that laterally " U " type is set is fixedly connected upper bearing (metal) outer end and lower bearing outer end, and the fixed mount passes through support
It is fixedly connected with TRT bottom, the rotating bar lower end is connected with the input shaft of the cluster engine.
The moving blade device includes wind blade, the only fast piece and the connection wind blade that are arranged on wind blade
With the reinforcement of the rotating bar, the wind blade is that arc is set and end is identical with the rotation pole length and fixed connects
Connect, the wind blade until top is set for the diminishing mode of length, and is reduced into vertical length along end at top
The tip-angled shape spent for 0 is set；The interior arc portion of the wind blade is provided with only fast piece, the only fast piece is divided into only fast piece hypomere
With only fast piece epimere, the only end of the only speed piece hypomere and the end and top of the top of fast piece epimere and the wind blade
Inversely set, and the end of the only fast piece hypomere is fixedly connected with arc portion in the wind blade, the plane of the only speed piece
It is α with the wind blade angle, and the angle of α is set to 39 ~ 61 °.
The material of the only speed piece hypomere is high-strength rubber, and the material of the only fast piece epimere is stainless steel, described to stop
The length of fast piece epimere is L, and the length of the only fast piece hypomere is L1, wherein L：L1=（2~2.5）:（1.5~1.8）.
The generating set is arranged on the lower end of the frame structure.
Preferably, the radian of the wind blade is 38 ~ 50 °.
Preferably, the position that is fixedly connected with arc portion in the wind blade of the end of the only fast piece hypomere with it is described
The distance of wind blade end：The position and the wind blade distance from top=（1~1.2）:（3.1~3.8）.
Preferably, the high-strength rubber material is calculated as by quality parts ratio：Natural rubber：52 ~ 60 parts, butyl rubber
Glue：5 ~ 8 parts, epoxy resin：2 ~ 3 parts, carbon black：10 ~ 15 parts, plasticizer：3 ~ 5 parts, polyethylene glycol：1 ~ 3 part, calcium sulfate：1~2
Part.
Preferably, the material of the only fast piece epimere is stainless steel, the stainless steel is by mass percentage：C：
0.09 ~ 0.12%, Si：0.5 ~ 0.8%, Mn：0.8 ~ 1.5%, Cr：3 ~ 8%, Mo：0.6 ~ 1.1%, V：0.15 ~ 0.35%, Ti：0.03~
0.05%, Ni：0.2 ~ 0.5%, P<0.02%, S<0.01%, N<0.008%, balance of Fe and inevitable impurity.
Preferably, the only fast piece is rectangular sheet structure.
Preferably, being also equipped with reinforcement between the only fast piece and the wind blade.
Preferably, the reinforcement set between the only fast piece and the wind blade is hard spring.
Effect of the invention is that：
1, by being provided with the vertical blade of arc, blade arc face is substantially parallel with the rotating bar being vertically arranged so that wind-force is sent out
The rotary shaft of electricity is vertical direction, so as to reduce the rotation of crosswind force power generation blade to energy change, reduce a lot
Part.And it is roomy by the way that arc wind blade is set into one end（End）, then progressively reduced to the other end until final
It is reduced into the form of wedge angle so that wind-force steps into arcwall face and partial air is stored in arcwall face and forms vortex,
Certain energy snubber is reached, so as to be supplied to the bigger more longlasting rotation potential energy of rotating bar.
2, stop fast piece by setting, and it is inversely arranged on arc wind blade so that be flowed into arc shaped blade
Interior moving air eddy currents are flowed into only fast piece, and are collided with only fast piece, so as to cause reverse power, to arc wind
Power blade is slowed down, and wind-force is bigger, and vortex radian is smaller, and the shock to only fast piece is fiercer, such that it is able to well in wind
Physics deceleration is carried out to arc wind blade when big, it is to avoid by outer increase part carry out what deceleration-operation was brought to axle
Cost increases the increase with consumable accessory.
3, only fast piece be with the angle of arc wind blade it is very important, it is too small to cause internal vortex maximum
The position being flowed into only between fast piece and wind blade of limit, if angle is too big（Especially greater than 90 degree）Even if, flowing
Air impact stops fast piece, and its kinetic energy is also positive transmission, that is to say, that be not to slow down, acceleration is likely to result on the contrary.Cause
This causes that slowing effect is maximized by the reasonable setting to the angle.
4, only the position of fast piece also it is critical that, it is necessary to radian and size according to arc shaped blade are arranged on vortex type
Into final position, only in this way using by the moving air of rotation with entered into the form of rotating only fast piece and arc shaped blade it
Between region stop fast piece so as to clash into a rotating manner.Therefore cause that the effect above reaches by the setting to only fast piece position
It is optimal.
5, due to only fast sector-meeting it is long-term be vortexed air impact, therefore its position be connected with arc shaped blade is very easy
Damage, by the way that only hypomere and epimere two parts will be set to by fast piece, and hypomere is set to the form of high-strength rubber, due to rubber
The elasticity of glue is very strong, therefore when moving air clashes into and stops fast piece, by the elasticity of rubber, alleviates itself and arc-shaped leaf
The shearing force of piece fixed position, simultaneously because there is provided rubber is used as hypomere, when vortex air lateral impact stops fast piece,
Only fast sector-meeting bends slightly outwards, so that the angle that air impact stops fast piece is smaller, alleviation further in turn
Destruction of the gas to only fast piece.The material of rubber is extremely important, if rubber is excessively soft, although elasticity meets requirement, but
Only fast piece angle change when being hit by the wind is too big, so as to destroy the angle for setting before, causes only effect to be beaten greatly
Discount, therefore by the improvement to quality of rubber materials so that what only fast piece also assures that deceleration in the case where durability is ensured can
By property.Only the epimere of fast piece is needed to be contacted with wind-force for a long time and clashed into by wind-force, therefore its intensity and atmospheric corrosion resistance also will
Ask higher, be improved by its material so that in the case where intensity ensures, atmospheric corrosion resistance is improved.
