Description
Technical field
The utility model relates to a kind of tubular multiblade wind wheel, belongs to blower fan field.
Background technique
Domestic and international wind-power electricity generation market does not have tubular multiblade wind wheel product.Existing lift and resistance type blade focus on few leaf in use, usually 3--5, brachium usually radius more than 1 meter, the mechanical characteristic of main outstanding torque force.Wherein blade support support body is the major spare part of radial space occupy-place, and the material of use is firm, and sophisticated technologies, threshold wind velocity is many at more than 2.5m/s.As can be seen here, the wind wheel Existential Space occupy-place of prior art is large, and Security is low, and cost is high, and in the problem that local-style dwelling houses cannot be popularized with commercial and urban construction market.
Summary of the invention
The utility model is for the problems referred to above, and technical problem to be solved in the utility model is to provide a kind of compression or the occupy-place of fixed diameter space, as far as possible or appropriateness use centripetal fan blade width to reach the brand-new blade that outstanding windage area exchanges motive power source for.
For realizing above-mentioned purpose of the present utility model, take following technological scheme:
A kind of wind energy conversion system tubular multiblade wind wheel, comprises end plates, dunnage and arc shaped blade.Wherein said arc shaped blade by blades installation arc and blade windward arc form, this blade and end plates and dunnage are uniformly distributed, blade outer rim and end plates and dunnage cylindrical tangent with angle.
Described end plates, dunnage and arc shaped blade adopt aluminum matrix composite.
Described aluminum matrix composite utilizes aluminium first to form keel base frame, then spray aramid fibre and carbon fiber and improve wind wheel integral rigidity and stretching resistance and anti-corrosion property energy.
Inwardly can to extend width of blade according to the requirement of windage area in inner edge, namely blade uses different in width.
Blade quantity is more than 24.
Installation arc and windward arc angle are 180-120 degree.
Arc arc length is 1--3 times that installs arc arc length windward.
Wind wheel windage area is 1.5-2 times of the specified windage area of generator;
The installation arc length of blade is 50-80 millimeter;
End plates and dunnage arc-shaped groove can not decile process, to increase the promotion of rotary centrifugal force.
The utility model has following beneficial effect:
1, fixing or restriction swept area of rotor ignores torque force, artificial compression volume occupy-place, and Security is high, reduces indirect cost, makes wind-power electricity generation be directly used in local-style dwelling houses and commercial and urban construction market, wind-power electricity generation can be made to move towards miniaturization, urbanization; The overall wind damage power of wind energy conversion system can be dissolved by the powerful wind-force of cutting fast.Super large uses windage area not only can solve the concentrated energy consumption issues of breeze start-up; Obtain enough wind-force switching energies simultaneously.
2, of a tightly knit structure, the stress equalization of tubular multiblade wind wheel; Under Wind power propelling, blade only produces centripetal force, and the structural failure under centrifugal action can not occur.
3, twice coating process of new high-tech material compensate for whole defects of aluminium material; Wind wheel overall unit proportion realizes light, and technique is simple, cheap.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
In figure: 1 tubular wind wheel end plates; 2 tubular wind wheel dunnages, 3 blades installation arcs, 4 blades arc windward.
Embodiment
Below in conjunction with embodiment and accompanying drawing, blower fan of the present utility model is described.
As shown in Figure 1-2, a kind of wind energy conversion system tubular multiblade wind wheel, comprise tubular wind wheel end plates 1, tubular wind wheel dunnage 2 and and arc shaped blade, wherein arc shaped blade by blades installation arc 3 and blade windward arc 4 form, this lonely shape blade and end plates and dunnage are uniformly distributed, blade outer rim and end plates and dunnage cylindrical tangent with angle.Namely in plate surface diameter bisectrix, arc chord length is installed in setting, and inwardly cutting out curve bath opening from cylindrical points of tangency is blades installation arc socket.Be as the criterion with end plates and dunnage and blade cutting graftage part, arc bevel cut opening windward, avoid plate face, allow arc plate face blade windward extend inwards.Blade composite sheet die mould is become 120-180 degree angle plate, then processing installation arc and windward arc respectively.After blade grafting, the notch of end plates and dunnage is sealed, prevent blade from outwards departing from, make Wheel structure fastening.This arc opening groove and the grafting of blades installation arc.
Wherein, end plates, dunnage and arc shaped blade adopt aluminum matrix composite, aluminum matrix composite utilizes aluminium first to form keel base frame, spray aramid fibre and carbon fiber again and improve wind wheel integral rigidity and stretching resistance and anti-corrosion property energy, inwardly can to extend width of blade according to the requirement of windage area in inner edge, namely blade uses different in width.Blade quantity is more than 24.Installation arc and windward arc angle are 180-120 degree.Arc arc length is 1--3 times that installs arc arc length windward.Wind wheel windage area is 1.5-2 times of the specified windage area of generator, and the installation arc length of blade is 50-80 millimeter, and end plates and dunnage arc-shaped groove can not decile process, to increase the promotion of rotary centrifugal force.
Adopt aforesaid way of the present utility model can limit tubular multiblade wind wheel diameter, grasp width of blade flexibly, with the extending space of stack shell length as supporting windage area.This outer cylindrical multiblade wind wheel can vertically, tilt or accumbency use.Blade support framework is substituted by end plates and dunnage.Blade is that two arc is integrally connected formed body.End plates and dunnage determine arc orientation fluting with the grafting of arc blade.Light and thin aluminium sheet only does wind wheel blade matrix, and its integral rigidity and tensility and corrosion resistance obtain reinforcement by twice coating.
The structure of tubular multiblade wind wheel of the present utility model decreases supporting part; Diameter space occupy-place reduces more than 50%; Due to mutliblade wind-force cutting effect, wind wheel starts dynamic balnce, and threshold wind velocity obviously reduces.Any power all can be converted into rotating power to the wind comes from.The axial wind-force of tubular multiblade wind wheel, through twice, front and back instantaneously act on wind wheel body.Therefore, wind energy utilization is higher.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.
