Abstract
The invention relates to scale combined blades. In the technical field of wind energy exploitation, theoretical knowledge on wind energy exploitation of people is always limited to interface wind energy collection, and a single-stage single-blade windmill with a single horizontal shaft is just the product of theoretical and technical application of interface wind energy collection. Blades of the single-stage single-blade windmill with a single horizontal shaft are arranged on a lateral plane from top to bottom and from right to left, only the cross sections of the windmill are provided with interface devices for collecting wind energy, and the windmill does not have the function of space wind energy collection. The scale combined blades are characterized in that blades of the single-stage single-blade windmill with a single horizontal shaft are arranged like scales in a shape of rhombus. Planar arrangement of blades in a lateral direction is reserved to guarantee conditions for interface wind energy collection, and space for wind energy collection is expanded in a vertical direction. The scale combined blades meet all the technical requirements for space and interface wind energy collection. Therefore, the essential difference between a single blade and scale combined blades are that the single blade belongs to the technical field of interface wind collection, but the scale combined blades belong to the technical field of space and interface wind energy collection.
Description
Technical field squama time combined blade is a fan blade of effectively developing wind energy in the wind energy development field, and the blade that mainly is used in horizontal axis windmill upgrades.
Background technique squama time combined blade is to invent the high efficiency combined blade of design for upgrading the existing horizontal axis separate single blade of replacement, is a kind of compound blade with respect to original single blade.In the technical field of wind energy development, the single blade windmill of single-stage of popular horizontal axis from tradition to current industry, the wind energy of being gathered all is the wind energy at one dimension interface in its occupied space, and lost take up space in a large amount of wind energies do not gather, the mode of collecting folk songs of the single blade windmill of single-stage of this horizontal axis is the mode of collecting folk songs of original low side, i.e. " interface " mode of collecting folk songs.The patent No. that Wang Wen improves invention clearly is multistage windmill of horizontal axis of ZL2008201110102, has changed the technology limitation of traditional " interface " collecting folk songs, and has opened up the axially technical pattern of " collecting folk songs in the space ".Though multistage windmill of horizontal axis, solved the basic fundamental problem of " collecting folk songs in the space " from multilevel hierarchy, but do not solve the technical problem of " collecting folk songs in the space " from the technical pattern of blade, the theory and technology that collect folk songs at " space-interface " does not still embody on windmill overall technology structure fully, also need to improve the blade of collecting folk songs, single blade that " interface " collected folk songs is improved to the squama time combined blade of " space-interface " collecting folk songs.Squama time combined blade is invented design for solving these technical problems, it both can be used on single-stage windmill of horizontal axis, more can be used on multistage windmill of horizontal axis, be installed on multistage windmill of horizontal axis, can form the technical pattern of collecting folk songs of graceful helical " space-interface ".
Summary of the invention in the field of wind energy development, since the tradition till now, on the theoretical and technical aspect that is confined to the learning concept of " interface " collecting folk songs and technology all the time.In theory, Wind Power Utilization effectiveness formula P=1/2 ρ * π * r
2* v
3, just explained the wind energy transformation and the utilization ratio at the interface that facings the wind, the wind energy that a certain specific space can provide and utilize can not be described.Technically, with horizontal axis windmill, traditional and existing windmill technology all are single-stage windmills, and blade all is that independent single blade plane is installed, and the wind energy of being gathered all is the facing the wind wind energy at interface of one dimension, lack the space of axially the stretching technology of collecting folk songs.Obviously, such theory and technology of collecting folk songs has very big limitation and disappearance, has lacked learning concept and the technical measures collected folk songs in the space.Any type of energy all is existence and moves in certain space.Motion is a kind of attribute of energy, does not have the space just not have motion, does not also have energy.Wind energy also is existence and moves in certain space that the exploitation wind energy is exactly the wind energy in the exploitation certain space certainly.To efficiently develop the wind energy in the certain space, must satisfy two conditions: the one, set certain wind energy development space, the 2nd, the interface device of the wind energy of gathering is set in the space that sets, as blade, the plate that facings the wind and so on, will satisfy " interface, space " two conditions in other words, Here it is, and collect folk songs at " interface, space ".Squama provided by the present invention time combined blade designs under the theoretical direction of collecting folk songs at " interface, space ".On the history of wind energy development technology, still with horizontal axis windmill, a single-stage windmill list blade installation technology is the original basic interface technology of collecting folk songs; The appearance of a multistage windmill has broken through the technology limitation of collecting folk songs in the interface, has opened up the new technology that collect folk songs at " interface, space "; The technological innovation of squama time combined blade is collected folk songs the simple interface of single blade and is brought up to the technology of " interface, space " collecting folk songs and become on the face.Squama time combined blade if be installed on the existing single-stage windmill, can remedy the single-stage windmill and lack the deficiency of collecting folk songs in the space, if be installed on the multistage windmill, can make " interface, space " technology of collecting folk songs of a multistage windmill of horizontal axis more perfect.
The technological scheme of squama time combined blade is such: one group of vane group of squama time combined blade is bonded to single blade stack mounting of wanting less more than 2 and forms.In one group of combined blade,, the single blade more than 2 is fixed on the base plate (1) apart from vertical arrangement by needed of specific design according to the size of single length of blade and width.In the blade combination arrangement mode of each single blade be press squama time shape from the front first single blade (31), the order of the 2nd single blade (32), the 3rd single blade (33) etc. is arranged down backward successively, has arranged up to single blade quantity that needs are made up.In the combination of one group of blade, tetragonal four angles that per two single blade bases are constituted on base plate (1) all are to be greater than or less than 90 ° angle, can not equal 90 °.If equal 90 °, just can not form rhombus squama time shape, can reduce the space efficient of collecting folk songs.The top of combined blade reinforces the connection with the blade of upper cover plate (2) with a plurality of combinations.In some cases, for example carry out high-power wind energy development, assemble high-power type, single blade must design very long, combined blade is inevitable very high, for firm purpose, can set up flat board reinforcing title that does not influence the efficient of collecting folk songs in middle part and bottom between combined blade.Below the base plate (1) of squama time combined blade is petiole (4), and petiole (4) uses the Placement that matches with wheel hub to be connected with the wheel hub of blower fan.Petiole (4) can be located at the centre of combined blade base plate (1), with existing Variable Pitch angle technology the angle of collecting folk songs of combined blade is regulated and control.Also can be located at the forward position of combined blade base plate (1) to petiole (4), the mechanical device that comparatively simple and easy practicality is installed is realized the collect folk songs auto-control of angle of squama time combined blade.In addition, in order to reduce the squama time on-stream resistance of combined blade, base plate (1) and upper cover plate (2) can be made into circular arc, and circular arc will same base plate (1) and upper cover plate (2) the circumference arc that circumferential running streaked separately consistent.
The basic fundamental structure of squama time combined blade as mentioned above.Basic building block mainly contains base plate, upper cover plate, single blade, petiole composition, sets up in the time of necessary to reinforce to claim son again.The adoptable single vane type of combined blade has three kinds: arc shaped blade, plate blade and wing blades.Used in this Figure of description is arc shaped blade, and arc shaped blade rotates tangible directivity is arranged installing and promote blower fan, and has the good performance of collecting folk songs.Divide according to the different arrangement mode of single blade in the squama time combined blade, have positive squama to arrange, i.e. during wind wheel running, front first single blade (31) is preceding, all the other single blades successively after; Have down squama time to arrange again, i.e. during wind wheel running, last single blade is preceding, front first single blade (31) on the contrary after.According to single blade angle position difference in the combined blade, can make wind wheel produce two kinds of different sense of rotation, promptly turn clockwise and the inhour rotation.
Squama time combined blade is compared with existing blower fan list blade, has the advantage of a lot of aspects.Applied blower fan list blade in the present industry, its technological essence is exactly the interface of an original wind energy of gathering substantially, does not have the technological component of creationary interpolation higher level.The technical characteristics of this original low side of single blade is determined by single blade itself.The wind energy of gathering at first with necessary realizing from the interface of collecting folk songs, single blade is exactly an original basic interface of collecting folk songs.Therefore, only can not effectively realize the effect that collect folk songs at " interface, space " with the technology of single blade.Only with the width of single blade, to a very wide single blade, if put the blade angle of collecting folk songs for a short time, the interface of collecting folk songs of blade is just big, but has shortened in the space of collecting folk songs axially; If the blade angle of collecting folk songs has been amplified, though the space elongation of collecting folk songs axially, the interface that facings the wind has diminished, and the resistance of blade movement is also big.These contradictions, single blade itself are unvanquishable, and single blade is to realize the technical requirements that collects folk songs at " interface, space ".Address these problems, must use the technological scheme of squama time combined blade.
Single blade is compared with squama time combined blade, technical characteristics and practical effect main difference be:
Original single blade--the-1st, can not design very widely because technology use to go up single blade, improving power can only be by adding linear leaf.The linear leaf manufacturing and transportation are installed all very difficult, also will increase the pylon height, and cost of investment increases, and the benefit of generation is little.The 2nd, single blade is independently installed, and can not interconnect dependence, and blade is long again, makes blade mechanism intensity variation, is broken by windbreak easily.The 3rd, because single blade is independently installed, each blade can not be connected to each other, and improves blade windproof mechanical strength, can only reinforce from root of blade, and the result causes technical contradiction, makes the degradation of collecting folk songs of root of blade.The 4th, single blade can only enlarge the area of collecting folk songs from transversely adding linear leaf, can not therefore, on the technical foundation of single blade, realize that the high-power exploitation of unit truly is very difficult from vertically expanding the space of collecting folk songs, or even impossible.The 5th, single blade can not be realized the theory and technology standard that collect folk songs at " interface, space ", is his essential technological deficiency in production application.
Squama time combined blade---the 1st, squama time combined blade closes from a plurality of single vane group and has solved existing single blade is used upper blade restricted width system in technology problem, thereby under the condition that does not increase single length of blade and width, enlarged the space of collecting folk songs of combined blade from the fore-and-aft direction of horizontal axis.The 2nd, squama time combined blade has been broken through the restricted technical problem of original single width of blade, solved the scaling problem of axial space, can promptly increase space and the area that two aspects of combined blade height and the single blade quantity that increases combined blade expansion blower fan is collected folk songs from adding linear leaf, just can realize enlarging space and the interface that blower fan is collected folk songs, for the high-power exploitation of unit truly provides the theory and technology support from two aspects of vertical and horizontal.The 3rd, the practicable multiple-blade of combined blade interconnects, and reinforcing for blade provides convenience, can adopt simple Scheme of Strengthening, both can prevent effectively that blade from being broken by windbreak, can save manufacture cost again.The 4th, under the condition of same length of blade, same spatial area, same pylon height, squama time combined blade can produce the wind energy development power that manys times than existing single blade; Conversely, under the condition that obtains the identical power of collecting folk songs, squama time combined blade can reduce length of blade, and the conserve space area reduces the pylon height, improves the firm safe effect of pylon, saves cost of investment.The 5th, squama time combined blade has been broken through the technology limitation of collecting folk songs in simple interface that original single blade plane installs, opened up the precedent of vertically installing along horizontal axis, for the new wind energy recovering device of ground versatile and flexible innovative design on " interface, the space " learning concept of collecting folk songs has been opened up new technology space, thereby effectively promote the innovation progress of wind energy development technology.The 6th, multistage windmill of horizontal axis of squama time combined blade and patented technology ZL200820111010.2 all is the technology product that collect folk songs at " interface, space ", it is the wind energy development technology that complements one another, these two technology are combined, can replace the single blade windmill of single-stage of existing horizontal axis with tangible technical advantage, for satisfying the demand of human society, produce important social and be worth and economic value green, environmental protection, the low-carbon (LC) energy.
