Background technique
Along with rapid development of social economy, human demand to the energy grows with each passing day.And wind energy resources more and more receives publicity as green energy resource, and this is because wind energy has huge superiority: 1, the wind energy reserves are big; 2, wind energy is a renewable energy sources, and is inexhaustible, nexhaustible; 3, wind energy is without any the clean energy resource that pollutes; 4, the wind energy turbine set construction period is short; 5, after wind energy turbine set was built up, operating cost was low, maintenance workload is little.So dynamics that the abundant country of wind energy resources all develops in the generating that breezes up.
Blower fan tower barrel is as the important component part of wind-powered electricity generation unit, (its underpart is a concrete structure for have steel tower tube, prestressed concrete tower tube, steel-concrete mixer column tube commonly used, top is steel tower tube), lattice tower tube or wooden tower barrel structure etc., modal tower tube is a steel tower tube in various countries' wind-powered electricity generation exploitation at present.
Blower fan tower barrel mainly bears pressure and the moment of flexure that transmits at the axial fan hub place, in the process of design tower tube, consider intensity, rigidity and the stability etc. of tower tube, be accompanied by the increase of the blower fan power of the assembling unit, present scheme mainly is to improve the strength and stiffness of tower tube by the diameter that increases the tower tube.Be accompanied by the exploitation of high-power blower, and in order to adapt to different wind field conditions, more and more higher to the requirement of tower tube hub height, the diameter of tower tube is also increasing, end flange diameter as the 3MW blower fan tower barrel reaches 4.5 meters, and the end flange diameter of 6MW blower fan tower barrel has reached 6 meters.
Existing steel blower fan tower barrel, and though enough strength and stiffness can be provided, when using, reality finds also to have some deficiencies in its structure, fail to reach best using effect, and its shortcoming can be summarized as follows:
1,, in order to improve the strength and stiffness of tower tube, need to increase the diameter of tower tube, and the diameter of steel structure tower tube can not increase unrestrictedly along with of the requirement of more powerful wind-powered electricity generation unit to the tower tube.
2, the design of major diameter tower tube, construction, transportation and mounting technique difficulty are bigger, to the requirement height of adpting flange, cost height.
This shows that above-mentioned existing blower fan tower barrel still has inconvenience and defective, and demands urgently further being improved in structure and use.How to found a kind of intended diameter that had both reduced the tower tube, can satisfy the novel fan tower tube of strength and stiffness again, real one of the important research and development content of current industry that belongs to.
The model utility content
The purpose of this utility model provides a kind of concrete filled steel tube blower fan tower barrel, makes it guarantee can to reduce tower tube diameter under enough strength and stiffness conditions, thereby overcomes the existing excessive problem of steel structure tower tube diameter that is used for the high-power wind turbine unit.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of concrete filled steel tube blower fan tower barrel comprises the inside and outside two-layer steel tower tube that is fixed on the blower foundation ring, the concrete layer for pouring between the described two-layer steel tower tube.
Further, described inside and outside two-layer steel tower tube is a concentric structure.
Further, described inside and outside layer steel tower tube is fixedlyed connected by flange with foundation ring respectively.
Further, described outer steel tower tube is a conical shell.
Further, described inside and outside layer steel tower tube is more than two sections, and fixedly connected by flange between adjacent two sections.
Further, the section of the end of described outer steel tower tube is a conical shell.
Further, described inside and outside layer steel tower tube all is with shear connector.
Further, the form of described shear connector is bead, pastes pin weldering band steel or paste the structural type that pin welds round steel.
Further, on the inwall of described internal layer steel tower tube ladder and/or half space are installed also.
Because adopt technique scheme, the utility model has the following advantages at least:
(1) owing to adopted double-deck steel tower tube and concrete layer structure, inside and outside tower tube bonds together by the chemisorption power between concrete and the steel, has strengthened the strength and stiffness of tower tube, has well born the stressed of structure.Because double-deck steel tower tube and concrete layer structure are born load jointly, reduce the diameter of tower tube greatly, can reduce about tower tube diameter 20%-30%, also reduced the diameter of tower tube bottom adpting flange and the wall thickness of tower tube simultaneously, be beneficial to transportation, installation etc., and save cost.
(2) because inside and outside layer steel tower tube all is with shear connector, inside and outside tower tube can bond together with bond stress and frictional resistance between the concrete by shear connector, has further strengthened the strength and stiffness of tower tube.
(3) owing to adopted double-deck steel tower tube and concrete layer structure, both reduced the intended diameter of tower tube, and can satisfy the strength and stiffness of structure again, applicable to high-power 3MW-12MW land counterpart, naval counterpart wind power generating set.
(4) owing to adopted concrete material in the tower barrel structure, the convenience, with low cost of drawing materials has significantly reduced the cost of investment of building the tower tube.
Description of drawings
Above-mentioned only is the general introduction of technical solutions of the utility model, and in order to more clearly understand technological means of the present utility model, the utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
