Problems solved by technology

This has led to some problems: such tall equipment must have many difficulties in manufacturing, transportation, installation, maintenance and management, and on this basis, it will be more difficult to make it higher and larger. It is also limited, and if the wind turbine cannot be made bigger and higher, the wind energy in the relatively higher space on the earth's surface cannot be fully developed and utilized, and the measurement practice just proves that the wind energy in the higher space relative to the ground has greater energy.
Here are some other problems: the construction of a medium-scale wind power station still needs to occupy such a wide area, and its site utilization efficiency is obviously not ideal
This scheme can utilize wind energy in a higher space on the ground, but there are still problems of insufficient installation density of wind turbines and unsatisfactory installed capacity per unit area

Embodiment 1

[0054] Embodiment 1 is based on the premise of better geographical, geological and wind energy conditions

[0055] For wind turbine selection, products with large models, large specifications, and mature technologies are preferred.

[0056] The height of the tower is designed according to the ideal height that can be achieved by the existing technology.

[0057] Tower pillars Construct 6 vertical cylindrical load-bearing columns whose diameters gradually shrink from bottom to top, distributed to form a regular hexagon, forming the innermost layer of the tower pillars, whose height is the total elevation of the main body of the tower. Then take the two load-bearing columns on the same side as the starting point, and with the same spacing width, radially outward, and build a certain amount of load-bearing columns in pairs from the inside to the outside at a certain distance, and the height is determined by the inner layer It is lowered outward in stages, and the innermost load-...

Embodiment 2

[0064] Embodiment 2 is based on the usual geographical, geological and wind energy conditions

[0065] Selection of wind turbines Choose medium-sized or large-scale products with mature technology.

[0066] The height of the tower is designed according to the height of more than 300 meters.

[0067] The pillar body of the tower is quadrangular: the cross-sectional area is consistent from bottom to top; it is closed from bottom to top, and the joint with the tower hanging building and the tower beam is the passage space, and each floor has a pedestrian door opening, and the top is closed as a platform structure. Install lightning protection devices.

[0068] The load-bearing columns are 4 to the top; cylinders are preferred; the diameter specification is gradually reduced from bottom to top; structural beams and auxiliary beams are constructed between adjacent load-bearing columns. Auxiliary beams and electric energy output wires are arranged on auxiliary beams, and the distr...

Embodiment 3

[0074] Take the tower pillar body composed of 3 load-bearing columns as an example

[0075] The main features of the implementation plan are: in order to ensure the stability and safety of the tower structure, when constructing the tower hanging building and the tower beam, first of all, at each corner of the triangle, that is, the point where the three load-bearing columns are located, and this point is the center of the construction. Three beams parallel to the corresponding side, each of which is four times the length of the corresponding side, form a group of scissor-shaped cantilever beams on the outside of each side of the triangle, and then use the scissor-fork cantilever beams as load-bearing cantilever beams And on the basis of it, build a tower hanging building and a tower hanging beam ( Figure 8 ).

[0076] Other embodiments are similar or similar to Example 2.

Abstract

The invention relates to a vertically-distributed wind power station structure. In the invention, a wind power station mounting tower is built in an area with wind power, wherein the tower is composed of a tower strut body, tower hoisting buildings and tower girders, has a plurality of stories and is hundreds of meters high; the tower strut body is a polygon structure which is composed of load-bearing columns; the tower strut body is provided with the tower hoisting buildings and the tower girders which are distributed radially are built outwards on the tower strut body at certain intervals from bottom to top, wherein the tower girders are arranged above the tower hoisting buildings; the tower girders are used for mounting wind turbines of vertical axial-type wind driven generators; the tower hoisting buildings are used for mounting generators and other components of the wind driven generators; the wind driven generators are distributed on the tower in a three-dimensional way; the tower can be constructed independently or multiple towers can constructed in a combined way or constructed in lines and rows.

Description

Technical field [0001] The invention relates to a three-dimensional distributed wind power station structure, in particular to a wind power station structure including a wind engine installation tower. Background technique [0002] At present, the known structure of a wind power station is composed of at least one set of wind turbines, one power transmission and transformation station, and power transmission wires. Usually wind turbines and other equipment are installed on the top of the tower, and the rotation axis of the wind turbine is perpendicular to the horizontal plane. [0003] In practice, in order to make full use of wind energy and improve the wind energy conversion efficiency of the wind engine, inventors and engineers design the wind engine as much as possible and install it higher. For example, it is known from searching on the Internet that the length of the wind rotor blades of large wind turbines is 77 meters, the height of the tower is 120 meters, and the ...
