Abstract
The invention discloses a steel-composite material fan tower cylinder, which comprises a steel inner pipe and a composite material outer pipe, wherein the steel inner pipe is formed by connecting a plurality of conical steel pipe sections; e-glass fiber cloth with anti-corrosion property is stuck on the surface of each steel inner pipe to form a steel-composite material combined segment; the steel-composite material combined segment is divided into two pieces along the circumferential direction; longitudinal stiffening ribs are arranged along the longitudinal direction of each sheet; each two steel-composite material combined sections are connected by high-strength bolts to finally form a steel-composite material tower cylinder section; and the steel-composite material tower sections are connected by flanges to form the steel-composite material tower for field installation. Compared with the traditional steel wind turbine tower, the steel-composite material wind turbine tower can effectively resist invasion of wind sand and wind waves, is fatigue-resistant and corrosion-resistant, and can ensure the service life of the tower.
Description
Technical field
What the present invention relates to is a kind ofly to be used for the coastal waters and marine large-scale wind field wind-power electricity generation supporting structure---steel-composite material blower fan tower barrel belongs to technical field of wind power generation.
Background technique
At present, the principal mode of wind-power electricity generation supporting structure is awl cartridge type steel tube tower, and generally the tower tube plurality of sections 20-30m is formed by connecting through flange, and supreme diameter reduces the tower tube gradually the end of from.Yet along with the large scale development trend of wind-powered electricity generation unit, the height dimension of tower tube increases thereupon, has surpassed the general limit for height 4.5m of China's expressway.Wind-power electricity generation just progressively develops from land to coastal waters, sea simultaneously, and traditional head tower tube will face serious corrosion problems.These are anticorrosion, a series of problems of processing and transportation installation aspect impact the development of wind-power electricity generation, become the developing bottleneck of wind-power electricity generation, need to be resolved hurrily.
Steel-composite material blower fan tower barrel is a kind of novel structure, and this structure is combined by steel inner cylinder and composite material urceolus.The fiber direction of composite material urceolus can design according to the structure needs, and fiber can be arranged along hoop, a plurality of directions such as vertical, form multi-layer fiber; Steel inner cylinder has the rigidity and the intensity of level and Vertical direction simultaneously.Advantage is separately given full play in steel inner cylinder and the collaborative work of composite material urceolus, has antiseptic power and mechanical property preferably.
Summary of the invention
The problems face are installed in anticorrosion, the processing and the transportation that the objective of the invention is to face to conventional fan head tower tube, propose a kind of novel blower fan tower barrel---steel-composite material blower fan tower barrel.
Technical solution of the present invention is:
A kind of steel-composite material blower fan tower barrel comprises interior pipe of steel that a plurality of conical steel pipe sections are formed by connecting and the composite material outer tube that is made up of a plurality of glass fiber compound material tube segment; The E-glass fiber cloth with anticorrosion character is pasted on the surface of in each steel, managing, and forms steel-composite material combined segments; This steel-composite material combined segments along the circumferential direction is divided into two; Along every longitudinal stiffener vertically is set; Adopt high-strength bolt to be formed by connecting between per two steel-composite material combined segments, finally form steel-composite material tower tube section; Adopt flange to be connected to form between each steel-composite material tower tube section and be used for field erected steel-composite material tower tube.
Described steel-composite material blower fan tower barrel, said E-glass fiber cloth adheres to steel through the epoxy resin of corrosion-proof type
Inner tube outer surface, said E-glass fiber cloth divides the two-layer every steel plate outer surface that is layed in by the accurate quadrature of four-axial.
Advantage of the present invention: (1) than the conventional steel blower fan tower barrel, and steel-composite material blower fan tower barrel can effectively be resisted dust storm, stormy waves invasion and attack, and endurance, corrosion-resistant can guarantee life-span of tower tube.Simultaneously, need not to carry out large-area metal rust preventing preservative treatment, so maintenance cost is low, it is lower that structure life-cycle process expense is compared traditional head tower tube, reduced manufacture cost; (2) adopt tower tube section burst, make things convenient for factory to stack, solved the restricted problem of the height of passing a bridge in the tower tube transportation process simultaneously, after factory normalization completes, on-site hoisting, it is also comparatively convenient to assemble; (3) because the composite material urceolus has the advantage of high-strength light, steel-composite material blower fan tower barrel wants high than clean steel tower tube intensity.

Embodiment
Below in conjunction with specific embodiment, the present invention is elaborated.
Please refer to Fig. 1, Fig. 1 is the cross sectional representation of steel of the present invention-composite material blower fan tower barrel.As shown in Figure 1, this
Steel-composite material blower fan tower barrel of providing of invention comprises the outer composite drum that pipe 1, a plurality of composite material tube segment constitute in the steel that a plurality of conical steel pipe sections connect and compose.Conical steel pipe sections and composite material tube segment all can be prefabricated in the factory and form.
Pipe is formed by connecting through stiffening rib 3 two curved surface steel discs in the steel of the present invention, and the high-strength bolt bolt that two stiffening ribs, 3 usefulness are passed bolt hole 4 forms, thereby finally forms pipe 1 in the steel.
Outer composite drum 2 of the present invention is by the accurate quadrature [0/45/90/-45/0/45/90/-45 of two-layer E-glass fiber cloth (GFRP) 8 four-axials; Be that the E-glass fiber cloth is laid with 0 °, 45 °, 90 ° ,-45 ° directions respectively] lay; And manage 1 bonding behind the employing epoxy resin cure with in the steel; Thereby form steel-composite material blower fan tower barrel section, as shown in Figure 2.
Connect through adpting flange 6 between the adjacent segment of pipe 1 in the steel of the present invention.Steel flange by the high-strength bolt that passes bolt hole 7 bolts together.
The present invention adopts the segmented making method of pipe in composite material outer tube and the steel, need not to transport long tube and large diameter tube, only needs to form steel-composite material blower fan tower barrel through the assembling between each member.Connector of steel tube is arranged on the outer surface of steel pipe among the present invention, has avoided carrying out in composite tube tower inside the difficulty of field operation.The composite material outer tube directly is bonded in the outer surface of pipe in the steel, forms steel-composite material blower fan tower barrel.
Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection domain of accompanying claims of the present invention according to above-mentioned explanation.
