Technical field
The utility model relates to a kind of wind power generating set support device, and particularly a kind of wind-powered electricity generation unit split blade type sleeve connects concrete-steel combined tower.
Background technique
Wind energy is a kind of reproducible clean energy resource, is the emphasis of various countries' new energy development and utilization, has also obtained developing rapidly in China in recent years, and China's wind-powered electricity generation installation total amount ranked first in the world in 2011.Pylon is as the support device of wind-powered electricity generation unit, and it directly influences the reliability of whole system.Pylon expensive, land breeze group of motors pylon cost surpass 10% in whole unit cost.Common pylon comprises tubular type pylon, concrete pylon and concrete-steel combined tower; The tubular type pylon generally adopts steel design, and is simple in structure, compact, but steel using amount is big, and cost is high; The concrete pylon has reduced manufacture cost to a certain extent, but onesize diameter intensity can not get guaranteeing that need to do very greatly, pylon is heavy to tower tube diameter; The concrete towers tube is adopted in concrete-steel combined tower bottom; Steel tower tube is adopted on top, and it combines the advantage of steel pylon and concrete pylon, but the diameter of concrete tower segment is excessive; Employing integrated type then preponderance is inconvenient to transport some engineering roadblocks that cast-in-site then causes.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides that a kind of cost is lower, reliability is high, is convenient to transport, wind-powered electricity generation unit split blade type sleeve easy for installation connects concrete-steel combined tower.
The technological scheme that the utility model adopts is: comprise tower body and concrete foundation, tower body places on the concrete foundation, and is affixed with concrete foundation; Said tower body is the cone barrel type structure, and in the vertical direction is divided into a plurality of tower sections, and nethermost tower section is a concrete tower segment; All the other are steel tower section; The joint of adjacent towers section is provided with sleeve, and said sleeve comprises urceolus and inner core, and the cylindrical shell of urceolus and inner core is provided with a plurality of bolts hole; The joint of tower section places between urceolus and the inner core, and is through bolt that two adjacent tower sections are affixed.
Above-mentioned wind-powered electricity generation unit split blade type sleeve connects in concrete-steel combined tower, and a plurality of bolts hole on the said sleeve are along the circumferential direction evenly arranged.
Above-mentioned wind-powered electricity generation unit split blade type sleeve connects in concrete-steel combined tower, and said pylon concrete segment along the circumferential direction is divided into the first concrete towers sheet, the second concrete towers sheet and the 3rd concrete towers sheet; The two ends of the first concrete towers sheet, the second concrete towers sheet and the 3rd concrete towers sheet vertically are equipped with boss, and boss is provided with bolt hole, and the first concrete towers sheet, the second concrete towers sheet and the 3rd concrete towers sheet are affixed each other through second bolt.
Above-mentioned wind-powered electricity generation unit split blade type sleeve connects in concrete-steel combined tower, and said boss material is a steel.
Compared with prior art, the beneficial effect of the utility model is:
1) the utility model is combined by concrete-steel, can satisfy the requirement of strength of pylon, good reliability.Partially prestressed concrete replaces steel, has reduced the steel using amount of pylon, has reduced the manufacture cost of pylon.
2) the utility model is done, and pylon steel section is made up of the N section at vertical direction, and each section tower tube is rolled by steel plate and is welded, and multi-segment structure is convenient to transportation.
3) the utility model effect split blade type concrete tower segment replaces integral concrete tower section, has solved the limit for height problem on the expressway, convenient transportation.Concrete tower segment is without cast-in-site, and a series of engineering roadblocks when having solved cast-in-site are convenient to batch production production.
4) the utility model adjacent towers section connects through sleeve, and reliability is high, easy for installation.
