Abstract
The invention relates to a supporting structure of a wind generating set, in particular to a mixed tower supporting structure capable of being used in a large-size land wind generating set. In the prior art, a supporting structure of the land wind generating set is mainly of a conical cylinder-type tower made of steel, the tower is transported to a wind field after being manufactured in a segmented mode, and then the tower is connected and installed to a foundation ring embedded into a foundation. The height of an ordinary road is limited to 4.5m, however, the diameter of the bottom of a 5MW set in the market has reached 6m; with the development of the wind power industry, the center height of a hub and the diameter of the tower become larger and larger, and especially, the diameter of the lower portion of the tower causes great difficulty to transportation and manufacturing of the tower. The mixed tower supporting structure is divided into two parts, the upper portion is the traditional conical cylinder-type tower made of the steel, the lower portion is other supporting structures, solutions are provided for design and installation of large-capacity wind generating sets and ultrahigh towers, and meanwhile, the economy of the supporting structure of the wind generating set is improved to some extent.
Description
Technical field:
The present invention relates to a kind of wind power generating set supporting structure.
Background technique:
The supporting structure of wind power generating set is mainly carried the gravitational load of wind power generating set and the aerodynamic load passed over from wind wheel.
The supporting structure of existing land wind-powered electricity generation unit is mainly by steel circular cone cartridge type pylon be embedded in advance basic foundation ring and connect and compose, foundation ring and basis are at the infield casting complete, circular cone cartridge type pylon is due to the restriction of manufacturing and transporting, usually be divided into several sections, be transported to the wind power generating set infield after being manufactured by tower cylinder factory, by bolt, carry out connection.
4.5 meters of Ordinary Rd limits for height, the tower diameter of wind power generating set is generally 4.2 meters at present, but the 5MW unit base diameter on market has been accomplished 6 meters, in transportation and manufacture, all causes very large difficulty, same cost also is increased considerably.And the further increase along with wind power generating set single-machine capacity and rotor diameter, pylon load sharply increases, pylon is more and more higher, the larger place for wind shear, the wind-resources exploitation also develops to higher height, wheel hub center height is also more and more higher, tower diameter is also increasing, especially pylon lower diameter, but be subject to the restriction of bolt connection and transport routes, tower diameter can not unrestricted increase, so steel circular cone cartridge type pylon has insurmountable narrow limitation while solving higher, more jumbo wind power generating set supporting structure.
Summary of the invention:
For solving existing steel circular cone cartridge type pylon because of capacity and superelevation pylon cause greatly design and transporting restricted situation, the invention provides a kind of can be for the mixing column frame support structure of large-scale land wind power generating set, this mixing column frame support structure is divided into two-part, top adopts traditional steel circular cone cartridge type pylon, but bottom adopts other supporting structure, two-part structure is joined together to form the supporting structure of wind power generating set.
But described other supporting structure can be jacket structure, concrete structure, truss structure.
Of the present invention a kind of can be for the mixing column frame support structure of large-scale land wind power generating set, can meet the tower design of the wind power generating set of different capabilities and arbitrary height, design and installation for jumbo wind power generating set and superelevation pylon provide solution, have improved to a certain extent the Economy of wind power generating set supporting structure simultaneously.
The accompanying drawing explanation:
Figure be a kind of can be for the mixing column frame support structure schematic diagram of large-scale land wind power generating set.
In figure: 1, circular cone steel cylinder formula pylon; But 2, other supporting structure.
Embodiment:
Below in conjunction with accompanying drawing, the invention will be further described.
Figure be a kind of can be for the mixing column frame support structure schematic diagram of large-scale land wind power generating set, from scheming, can find out, this mixing pylon is divided into two-part, top adopts traditional circular cone steel cylinder formula pylon (1), but bottom adopts other supporting structure (2), and two-part structure is joined together to form the supporting structure of wind power generating set.
But described other supporting structure (2) can be jacket structure, concrete structure, truss structure.
Of the present invention a kind of can be for the mixing column frame support structure of large-scale land wind power generating set, combination by two kinds of structures, can meet the tower design of the wind power generating set of different capabilities and arbitrary height, design and installation for jumbo wind power generating set and superelevation pylon provide solution, have improved to a certain extent the Economy of wind power generating set supporting structure simultaneously.
Although, through the present invention is described in conjunction with specific embodiments, for the personage skilled in the art, substituting, revising and change of making according to narration above will be apparent.Therefore, such, substitute, when modifications and variations fall in the spirit and scope of claim of the present invention, should be included in the present invention.
Claims (2)
- One kind can be for the mixing column frame support structure of large-scale land wind power generating set, it is characterized in that: top adopts traditional steel circular cone cartridge type pylon, but bottom adopts other supporting structure, two-part structure is joined together to form the supporting structure of wind power generating set.
- 2. a kind of can, for the mixing column frame support structure of large-scale land wind power generating set, it is characterized in that according to claim 1: but described other supporting structure can be jacket structure, concrete structure, truss structure.
