The frustum-shaped tower drum is formed by fixedly mounting coaxial reinforced concrete frustum units vertically, the frustum unit of the lowest layer is fixedly mounted on the foundation on the ground, and the frustum unit of the highest layer is fixedly equipped with the generating device and the fan blades. The reinforced concrete prefabricated wind power generating tower drum is extremely simple in integral structure, and reasonable and scientific in design, effectively resolves the problems of high cost and difficult maintenance in prior wind power generation, has longer service life and permanent economic benefits compared with the conventional steel tower drum, thereby absolutely replacing the existing wind power generating tower drums.
Description
Technical field
The utility model belongs to wind power generation field, especially a kind of reinforced concrete prefabricated wind power generation stepped drum.
Background technology
Existing wind-driven generator is made of tower tube, rotation flabellum and generating set, and rotation flabellum and generating set generally are packed in the upper end of tower tube, and the tower tube is packed on the basis on ground.Because flabellum and generating set are heavier, need the tower tube to carry out strong support, so the tower tube need possess support force indexs such as stronger rigidity, intensity, and its material generally selects for use steel material to make.In today that iron ore rises steadily, the price moving quickly upward of steel causes the tower tube cost of the wind-driven generator made by steel also more and more higher, has strengthened the cost of wind power plant thus, has influenced the development of this green energy resource of wind-power electricity generation.As everyone knows, removing to bear pressure with steel is the most uneconomic mode, so the tower tube of present wind-driven generator does not reach the effect of economic optimumization fully, awaits adopting a kind of the most economical and the most practical new product to replace.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, simple in structure, design science is provided, can effectively reduces a kind of reinforced concrete prefabricated wind power generation stepped drum of cost of wind power generation.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of reinforced concrete prefabricated wind power generation stepped drum, constitute by flabellum, generating equipment, tower tube, flabellum and generating equipment are installed in the upper end of tower tube, the tower tube vertically is packed on the basis on ground, wherein said tower tube is vertically installed mutually by coaxial steel concrete frustum unit and is frustum, the frustum unit of the bottom is packed on the basis on ground, and the frustum unit of the superiors installs generating equipment and flabellum.
And, coaxial insert reinforcing cage in the steel concrete of described steel concrete frustum unit, this reinforcing cage is one deck ring cage, or the multistory reinforced ring cage that is constituted by the bearing rod mode.
And, adopt the bell and spigot mode to carry out coaxial installing between the described upper and lower adjacent frustum unit, perhaps adopt the flange mode to carry out coaxial installing.。
And described frustum unit at the bottom is reserved with an access.
And described steel concrete adopts steel fibrous concrete to substitute.
Advantage of the present utility model and beneficial effect are:
1. this wind power tower drum main body adopts reinforcing bar, concrete reinforced concrete structure, has simplified manufacture craft, has reduced cost of manufacture, has improved the universal scope of wind-power electricity generation effectively.
2. to have adopted steel concrete be main structure body to this wind power tower drum, and steel wherein are in the concrete alkaline environment, it well protected, thereby need not brushing rustproof paint often, saved maintenance cost greatly.
3. the utility model overall structure is very simple, and design science is reasonable, efficiently solves cost height that existing wind-power electricity generation exists, keeps in repair difficult problem; And with respect to traditional sense steel tower tube, the utility model longer service life has permanent economic benefit more, fully alternative existing wind power tower drum.
