Technical Field

The invention relates to the field of wind power projects, in particular to an auxiliary blade supporting device.

Background

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, in a wind power project, a large operation surface platform is needed for installation of a fan, so that space occupation of a crane, stacking of fan equipment and ground combination of impellers can be met, the impeller combination and hoisting in place have the highest requirement on the field area, and the requirement is usually 2500 square meters (50m × 50m), which cannot be met under the condition of a complex mountain wind power 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.

Disclosure of Invention

The present invention aims to solve the above-mentioned disadvantages of the prior art.

In order to achieve the purpose, the invention provides an auxiliary blade supporting device, which comprises an embedded foundation below zero meters and a supporting device above zero meters; the embedded foundation comprises a plurality of reinforcing steel bars which are positioned on the fan foundation and are encircled into a circle, the upper parts and the lower parts of the reinforcing steel bars are distributed and connected with an upper end plate and a lower end plate, embedded bolts are installed on the reinforcing steel bars, and reinforced concrete is poured around the reinforcing steel bars; the supporting device is cylindrical, the bottom end of the supporting device is connected with the embedded bolt, and the top end of the supporting device is connected with the hub through the double-headed screw.
