In terms of existing technologies, the motor of equal-wattage, hollow shaft 42 have not only reduced cost for solid shaft, and have greatly alleviated the weight of motor self.
Embodiment three
As shown in Figure 1, blade 1 adopts flexible material, and hydrocarbon polymer polylefins makes as macromolecule, can be screw type or airfoil.Upper bracket 31, middle bracket 32 and lower bracket 33 all can be around vertical central axis 2 rotations, and the end points of three supports is connected with the upper, middle and lower of blade 1 respectively, three blades 1 after the installation evenly are provided with around vertical central axis 2, and are screw type or S type from top to bottom.Certainly, the blade after the installation 1 can be a straight line type from top to bottom also.Because blade 1 is flexible material, can't be connected as a single entity by welding between itself and upper bracket 31, middle bracket 32 and the lower bracket 33, must be fastenedly connected by link 5.
No matter blade 1 is wing blade, screw type or S type, upper bracket 31, middle bracket 32 and 33 first fixedly staggering as required of lower bracket are arranged on the vertical central axis 2 during installation, and blade 1 connects with each support end points and gets final product.
But because blade 1 is to adopt flexible material to make, can twist very easily, even the blade 1 after therefore requiring to install is type or S type in the shape of a spiral from top to bottom, blade 1 also can need not to be processed into abnormal shapes such as screw type or S shape, directly be processed into straight shape, get final product (as shown in Figure 5) as wing blade according to commonsense method.It can be reversed when mounted to being connected with upper bracket 31, middle bracket 32 and lower bracket 33 after the required shape.With respect to special-shaped blades such as screw type or S types, wing blades 1 not only production and processing is simple, has greatly reduced cost of production, and more convenient transportation.
Under the effect of wind-force, blade 1, upper bracket 31, middle bracket 32 and lower bracket 33 are around vertical central axis 2 rotations, thereby the outboard rotor that drives motor 4 rotates the generation electric energy around stator.
In the present embodiment, blade 1 can be one or more (for balance, when having only a blade 1, blade 1 should revolve three-sixth turn around vertical central axis 2 from top to bottom), and support also can be at least one, as only using middle bracket 32.Use the stability and the balance of three supports better in the present embodiment.
Embodiment four
On the basis of previous embodiment, being connected of upper bracket 31, middle bracket 32 and lower bracket 33 can be adopted following structure:
As shown in Figure 1, upper bracket 31 is connected by being set in vertical central axis 2 outer axle sleeves 34 with middle bracket 32.Axle sleeve 34 structures as shown in Figure 6, the upper end is provided with upper end cap 341, the lower end is provided with lower end cap 342.Upper end cap 341 is connected by bolt with middle bracket 32 with upper bracket 31 respectively with lower end cap 342 or rivets.Also connect between same middle bracket 32 and the lower bracket 33 by axle sleeve 35.
Annexation such as Fig. 7, shown in Figure 8 of motor 4 and support and axle sleeve.Middle bracket 32 is connected by screw with the lower end cap of motor loam cake 45 with axle sleeve 34 respectively, and the lower cover of the upper end cap of axle sleeve 35 and motor 4 46 is connected by screw.Under the effect of wind-force, middle bracket 32, axle sleeve 34, axle sleeve 35, motor loam cake 45, lower cover 46 rotate synchronously around vertical central axis 2, and hollow shaft 2 does not rotate because of fixedlying connected with vertical central axis 2 with pcb board 47.
Certainly, also can not reverse support by force, the blade 1 after the installation is straight from top to bottom, is not to be S type or screw type.
For the blade 1 after need installing be screw type or S type from top to bottom, and blade 1 is when also being screw type or S type, and first three supports are adjusted after the angle as required with bolt and axle sleeve 34 and axle sleeve 35 fixes, and installs blade 1 and gets final product.
Adopt this structure, the installation of blade 1 is more simple.Each parts such as blade 1, vertical central axis 2, upper bracket 31, middle bracket 32 and lower bracket 33, motor 4, axle sleeve 34, axle sleeve 35 all can disassembled for transport, has greatly reduced cost of transportation.And install and also to become very simple, need not large-scale setting tool such as welding machine.
In the present embodiment, blade 1 can one or more (for balance, when having only a blade 1, blade 1 should revolve three-sixth turn around vertical central axis 2 from top to bottom), support also can be at least two, and the support between linking to each other adopts above-mentioned axle sleeve to connect and gets final product (structure that need not to adopt axle sleeve when having only a support).Certainly, also can be to determine to stagger the fixedlying connected of angle in advance between axle sleeve and each support.
Embodiment five
When the high-power generating of needs, the size of the overall dimensions of previous embodiment, especially support big (the support rotating diameter as the 10KW blower fan system is 6 meters, and the support rotating diameter of the blower fan system of 20KW is 9 meters) makes the manufacturing difficulty of support.Therefore, can do following improvement to the structure of support:
As shown in Figure 9, be example with middle bracket 32, it comprises the center bearing bracket 321 that is connected with vertical central axis 2, connects the connecting plate 322 of blade 1 and center bearing bracket 321.Be rigidly connected by link 5 between connecting plate 322 and the blade 1, adopt riveted joint or bolt to be rigidly connected between connecting plate 322 and the center bearing bracket 321.
Embodiment six
On embodiment five basis, link 5 of the present invention can adopt following structure:
For the ease of being inserted in blade 1,, can piece together complete vanes fixed part 51 by open loop clipping device 511 and base plate 512 two-part as Figure 11 and shown in Figure 12.Because blade 1 is made for flexible material, snaps in the open loop clipping device 511 after can being out of shape slightly, the base plate 512 that closes subsequently is complete vanes fixed part 51.Correspondence is provided with screw 513 on base plate 512, blade 1 and the open loop clipping device 511, and bolt passes these screws 513 they are fastenedly connected.
The end that connects upper bracket 31, middle bracket 32 or lower bracket 33 for convenience, support fixed block 52 can adopt following structure: as shown in figure 13, support fixed block 52 comprises two intermediate plates 521 parallel or that adapt to support end surface shape, and intermediate plate 521 vertically is built up on the base plate 512.Slit between the intermediate plate 521 can hold the support end and be inserted in.Be equipped with corresponding screw 522 on two intermediate plates 521 and the support end, it is terminal fixing with intermediate plate 521 and support that bolt passes these screws 522.
