Position or position relationship are for only for ease of the description present invention and simplify description rather than instruction or imply signified device or member
Part must have specific orientation, with specific azimuth configuration and operation, therefore be not considered as limiting the invention.
The accommodation method of wind turbine according to embodiments of the present invention is described below with reference to Fig. 1-Fig. 5.
As Figure 1-Figure 4, wind turbine 100 according to embodiments of the present invention, including：Babinet 1, volute 2, air inlet guide duct 3,
Outlet air guide duct 4.Babinet 1 has air inlet 11 and air outlet 12, and volute 2 is located in babinet 1, and the outlet air end direction of volute 2
Air outlet 12 is set, and air inlet guide duct 3 is located at the air inlet 11 of babinet 1, and air inlet guide duct 3 includes being located at 1 outside of babinet
Air inducing pipeline section 31, outlet air guide duct 4 are located at the air outlet 12 of babinet 1.
The accommodation method of wind turbine 100 according to embodiments of the present invention is：When wind turbine 100 is stored, air inlet guide duct 3 is overturn
It is mounted on afterwards at air inlet 11, and air inducing pipeline section 31 is located in babinet 1.
That is, as shown in figure 3, wind turbine 100 in normal use, air inlet guide duct 3 air inducing pipeline section 31 be located at case
The outside of body 1, and as shown in Figure 1, the air inducing pipeline section 31 that wind turbine 100 in storage, enters the wind guide duct 3 is located at the inside of babinet 1.
The accommodation method of wind turbine according to embodiments of the present invention, it is possible to reduce the packaging volume of wind turbine 100, saving are packaged into
This, and so that more wind turbines 100 can be placed in a container, reduce logistics cost.
In some embodiments, as shown in figure 3, wind turbine 100 further includes filter screen 5, filter screen 5 is located in babinet 1 and court
It is set to air inlet 11.The wind that wind turbine 100 is blown out as a result, more cleans after filtering, health.
It should be noted that since wind turbine 100 is in normal use, the air inducing pipeline section 31 of air inlet guide duct 3 is located at babinet 1
Outside, air inlet guide duct 3 inner space of babinet 1 is interfered it is few, at this time filter screen 5 can neighbouring air inlet 11 set.But
When wind turbine 100 is stored, since the air inducing pipeline section 31 of air inlet guide duct 3 is located at the inside of babinet 1, volute 2 is with entering the wind in babinet 1
There is no enough spaces between mouth 11 to place filter screen 5.At this point, filter screen 5 can be placed on to the one side of air inducing pipeline section 31,
And filter screen 5 is set parallel to air inducing pipeline section 31.As shown in Figure 1, filter screen 5 is placed on the one side of volute 2 and air inducing pipeline section 31.
Filter screen 5 is so stored, is also beneficial to make full use of the inner space of babinet 1, reduces the box volume of wind turbine 100.
In embodiments of the present invention, when wind turbine 100 is stored, the air inducing pipeline section 31 for entering the wind guide duct 3 is mounted on babinet 1
Inside, can there are many mounting means realize.
For example, air inlet guide duct 3 can be removably mounted on babinet 1, so when wind turbine 100 is stored, can will enter the wind
Guide duct 3 is removed from babinet 1, afterwards turns over air inlet guide duct 3, and air inducing pipeline section 31 is inserted into air inlet 11, at this time
Air inlet guide duct 3 will no longer occupy excessive storage volume.
In certain embodiments, as depicted in figs. 1 and 2, entering the wind guide duct 3 includes flange 32, and flange 32, which is located at, to be drawn
The end of air hose section 31, flange 32 are detachably connected on babinet 1.Specifically, multiple mounting holes, case can be set on flange 32
Corresponding multiple connecting holes can be equipped on body 1, flange 32 can be fixed by screws on babinet 1.It is set on air inlet guide duct 3
Flange 32, positioning is easy, easy to connect.
Optionally, it is recessed to be increasingly towards volute 2 on the direction towards air inlet 11 for the part of the circular air inlet 11 of babinet 1
Enter to set.That is, babinet 1 is formed as the notch board inwardly concaved for installing the side plate of air inlet guide duct 3, it can in storage
Air inlet guide duct 3 is inserted into along recessed direction in babinet 1, operation is very laborsaving.
Certainly, the connection mode entered the wind between guide duct 3 and babinet 1 can be without being limited thereto, for example, air inlet guide duct 3 can
It is installed in rotation on babinet 1, so when wind turbine 100 is stored, air inlet guide duct 3 on babinet 1 can directly be overturn, overturn
The air inducing pipeline section 31 for entering the wind guide duct 3 afterwards is located at the inside of babinet 1, and excessive packaging container will not be occupied by entering the wind guide duct 3 at this time
Product.
Such as in other specific embodiments, as shown in figure 5, air inlet guide duct 3 includes linkage section 33, linkage section 33 is located at
The end of air inducing pipeline section 31, linkage section 33 are connected to by shaft 13 on babinet 1.It is whole rotationally that guide duct 3 is entered the wind as a result,
It is connected on babinet 1, it is easy to operate when storing wind turbine 100, and need not will enter the wind guide duct 3 and be removed from babinet 1, it avoids
Part is caused to lack when removing.
Specifically, clamping structure (not shown) is may be provided between linkage section 33 and babinet 1.It is understood that work as
Mass air flow sucks babinet 1 by entering the wind guide duct 3 when wind turbine 100 uses, and air-flow impacts larger, air inlet to air inlet guide duct 3
Guide duct 3 easily rocks.Therefore clamping structure should be set between linkage section 33 and babinet 1, can will be entered the wind when wind turbine 100 uses
Guide duct 3 is stuck in securely on babinet 1, avoid generating rock, noise etc..
Advantageously, at least part of 31 scalable setting of air inducing pipeline section, that is to say, that the length of air inducing pipeline section 31 can elongate
Or shorten.As a result, when wind turbine 100 is stored, air inducing pipeline section 3 can be foreshortened to most short, the occupancy body of reduction air inlet guide duct 3
Product, and when wind turbine 100 in use, again elongating air inducing pipeline section 3, guarantee air inlet guide duct 3 plays good air inlet guiding function.
In the optional example of the present invention, the epipleural of babinet 1, can also be such as figure either independent one piece of metal plate
The epipleural of babinet 1 shown in 4 is spliced by 2 pieces or 3 pieces of metal plates.
Storage mode for ease of the structure to wind turbine in the embodiment of the present invention 100 and wind turbine 100 is further understood,
Below in conjunction with two specific embodiments, to describe the structure of wind turbine 100 and storage process.It should be noted that different
