After a wind power project is built in China for more than ten years, particularly after rapid development in recent years, high-quality wind power construction sites are utilized, and it is difficult to find a mountain wind power construction site with high power generation amount and good construction conditions, so that in order to obtain high power generation amount, a fan position is usually selected on a ridge when the mountain wind power project is selected. However, the wind turbine installation of the wind power project needs a large working surface platform to meet the requirements of crane occupation, fan equipment stacking and ground combination of the impellers, wherein the requirements on the site area are the highest when the impellers are combined and hoisted in place, and 2500m is needed under the common condition2(50m is multiplied by 50m), which cannot be met under the condition of mountainous wind power complex terrain.
There are currently three approaches:
1. a large truck crane hoisting scheme. And hoisting fan equipment by adopting a truck crane of more than 1200 t. On one hand, the mechanical cost is too high, and on the other hand, the automobile crane above 1200t cannot meet the hoisting requirement along with the increase of the single-machine capacity of the wind turbine generator.
2. And excavating and backfilling earth and stone to enlarge the area of the machine platform. The area of a machine position platform is enlarged mainly through slope reinforcement treatment, time consumption is long, cost is high, and high slope stability is insufficient.
3. And the elevation is reduced to meet the area of the machine position platform. Through the excavation of earth and rockfill, reduce basic elevation, though can obtain bigger machine position platform area, nevertheless to the environmental destruction great, the back is reduced to the elevation simultaneously, will influence wind power, influences the generated energy then.
Therefore, under the existing conditions, an auxiliary device is urgently needed to be developed, which not only can fill the ground of the impeller for combined hoisting, but also can reduce the requirement on the platform area, thereby reducing the mountain wind power construction cost and reducing the requirement on site selection of the mountain wind power construction.

Detailed Description
The terms "first," "second," and the like in the description and in the claims and in the drawings of the present invention are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprises" and "comprising," as well as any variations thereof, are intended to cover a non-exclusive inclusion, such as a list of steps or elements. A method, system, article, or apparatus is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, system, article, or apparatus.
The technical solution of the present invention will be described in further detail with reference to the accompanying drawings and embodiments.
As shown in fig. 1-5, the utility model provides a blade auxiliary supporting device, including the pre-buried basis 1 below zero meters and the strutting arrangement 2 above zero meters.
The embedded foundation 1 comprises 24 reinforcing steel bars 11 which are positioned on the fan foundation 5 and are encircled into a circle, the upper parts and the lower parts of the 24 reinforcing steel bars 11 are respectively connected with an upper end plate 12 and a lower end plate 13, embedded bolts 14 are installed on the reinforcing steel bars 11, protective covers are installed on the embedded bolts 14, and reinforced concrete is poured around the reinforcing steel bars 11. Wherein, pre-buried basis 1 pours integrative with fan basis 5 in the same time.
