Background technique
Existing wind-driven generator is made of tower tube, rotation flabellum and equal generator set, and rotation flabellum and generator set generally are packed in the upper end of tower tube, and the tower tube needs support force indexs such as stronger rigidity, intensity, so the tower tube adopts steel material to make.In today that iron ore rises steadily, the tower tube cost of wind-driven generator is more and more higher, causes the cost of wind power plant to increase year by year, has had a strong impact on the development of this green energy resource of wind-power electricity generation.As everyone knows, it is the most uneconomic removing to bear pressure with steel, so the tower tube of present wind-driven generator does not reach economic optimumization fully, awaits adopting a kind of the most economical and the most practical new product to replace.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, simple in structure, design science is provided, can effectively reduces a kind of wind power tower drum of cost of wind power generation with precast reinforced concrete pillar.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of wind power tower drum with precast reinforced concrete pillar, constitute by flabellum, power generating equipment, tower tube, flabellum and power generating equipment are installed in the upper end of tower tube, the tower tube vertically installs on the ground, described tower tube is made of steel king-post and reinforced concrete pillar, the king-post upper end installs flabellum, and king-post installs with pilum is coaxial, and the bottom frustum unit and the basis, ground of pilum install.
And described pilum is the multistory reinforced concrete frustum unit coaxial taper type structure that forms that installs mutually, is hollow structure in it.
And, coaxial insert reinforcement cage in the reinforced concrete of described each frustum unit, this reinforcement cage is a circular layer, or the multistory reinforced ring cage that is constituted by the bearing rod mode.
And the coaxial mode that vertically installs mutually in described frustum unit is to adopt the flange mode to carry out coaxial installing between the upper and lower adjacent frustum unit, adopts the joint socket mode to carry out coaxial installing between the perhaps upper and lower adjacent frustum unit.
And described reinforced concrete adopts Steel Fiber Reinforced Concrete to substitute.
And described bottom frustum unit is reserved with a gateway of being convenient to later maintenance.
Advantage of the present invention and beneficial effect are:
1. this wind power tower drum employing hollow taper type reinforced concrete installs the mode of steel king-post as pilum, on this pilum, has reduced the steel using amount of steel king-post effectively, has reduced manufacture cost, has promoted the application popularization scope of wind-power electricity generation.
2. the pilum of this wind power tower drum has adopted reinforced concrete, and steel wherein are in the concrete alkaline environment, and it is well protected, thereby need not brushing rust proof paint often, has saved maintenance cost greatly.
3. overall structure of the present invention 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 steel using amount reduces a lot; With respect to traditional sense all steel system tower tube, longer service life of the present invention has permanent economic benefit more, fully alternative existing wind power tower drum.

Embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
Embodiment 1: referring to Fig. 1, Fig. 3.
A kind of wind power tower drum with precast reinforced concrete pillar, constitute by flabellum 1, power generating equipment 2, tower tube, flabellum and power generating equipment are installed in the upper end of tower tube, the tower tube vertically installs on the ground, and flabellum is connected with power generating equipment by transmission shaft (among the figure not label) and imports transfer motion power; Power generating equipment is the same upper end that is installed in the tower tube with routine in the present embodiment, also can be installed in the tower tube or on the ground by transmission.Innovative point of the present invention is: the tower tube vertically installs the pilum 4 that is constituted mutually and constitutes by steel king-post 3 and reinforced concrete frustum unit are coaxial, the king-post upper end installs flabellum and power generating equipment, king-post carries out coaxial installing with pilum by modes such as flange or lower margins, and the bottom frustum unit and the basis, ground of pilum install.Pilum is the multistory reinforced concrete frustum unit coaxial taper type structure that forms that installs mutually, is hollow structure in it.Coaxial insert reinforcement cage 8 in the reinforced concrete of each frustum unit, this reinforcement cage can be a circular layer, perhaps can be the multistory reinforced ring cage that is constituted by the bearing rod mode, is Compound Steel muscle ring cage in the present embodiment accompanying drawing 3.Adopt the flange mode to carry out coaxial installing between the upper and lower adjacent frustum unit, that is: each frustum unit all thereon, two ends are fixed with flange 5 down, and the flange of next frustum unit carries out coaxial installing with the tight mutually tipping of flange of a last frustum unit and by bolt.
The pilum height of this structural tower tube can be controlled at 1-12m, highly reaches as high as 120 meters, and the external diameter of frustum unit, bottom can reach 4-6 rice, and top frustum external diameter is a 2.6-3 rice, and reinforced concrete tower barrel is thick to be 300-600mm.
Pilum diameter of the present invention dwindles from the base foundation to the top gradually, unit weight is also corresponding to be reduced gradually, adopt the design concept of steel tension, concrete compression, so just can make reinforcing bar, concrete obtain organic assembling, reach the most economical and the most practical purpose.
