Construction engineering structure mode for tower wind power generation station

Abstract

The invention provides a vertically-distributed construction engineering structure mode for a wind power generation station, which sets up a building tower in the wind power area. The tower is composed of a main body, a girder and a hoisting building and has a plurality of stories. The main body of the tower is a framework structural body four corners of which are load-bearing columns and the middle of which is a space, and an internal space thereof is taken as an up-down channel. The main body of the tower is externally and alternately provided with symmetrical girders and hoisting buildings in left-right directions or front-rear-and-left-right directions in a certain height, wherein, the girder is arranged at the upper side and the hoisting building is arranged at the lower side. The girder is used for installing the turbine of a vertical and axial wind generating set; and the hoisting building is used for installing the generator and other components of the wind generating set. The wind generating set is vertically distributed on the tower. The tower can be individually constructed or constructed in a multiple combination manner or constructed in a distribution manner in rows and lines.

Description

Technical field [0001] The invention relates to a construction engineering structure mode of a wind power station, especially an engineering structure mode suitable for the construction of a large wind power station. Background technique [0002] At present, the existing wind power station construction engineering structure method is usually to install the wind power generating sets in a distributed manner on the ground. Since the installation distance between single units is generally more than tens of meters, a wind power station with a total installed capacity of more than hundreds of thousands of kilowatts requires a site area ranging from tens of square kilometers to hundreds of square kilometers. Therefore, it is usually not called a wind power station, but a wind farm. Wind turbines in wind farms generally adopt a horizontal axis structure. At present, the diameter of the swept area of ​​the wind turbine blades reaches 100 meters, and the total height of the unit exc...

AI Technical Summary

Problems solved by technology

[0004] 2. The installation density of the unit is low, and only a single level of space on the ground is used

Due to the inherent geographical limitation, its development space is limited

[0005] 3. In the current large horizontal axis wind turbines, the sweeping diameter of the wind blades is already huge, and the height of the tower is difficult to increase

To further increase the capacity of a stand-alone machine, the technical difficulty is becoming more and more difficult, and the potential for increase is limited

[0006] 4. The generator sets are distributed and installed on the ground of tens to hundreds of square kilometers, the distance between the generator sets is very far, the connection cost of the power network cable is high, and the loss in the process of power collection is large

Because the units are distributed in the vast wilderness, it brings difficulties to management and maintenance, and the maintenance cost increases

The equipment is operated in the field, and the service life is adversely affected
