Description
Technical field
This utility model is related to new bending and molding multiple combined-type wind power tower.
Background technology
A basic device in wind-powered electricity generation industry during wind power tower, due to carry be worth expensive generating equipment requiring have compared with
Strong anti-typhoon capacity, so pylon requires firm, reliability；Existing wind power tower generally using segmentation welding by the way of, and
Per section of physical dimension is big, weighs very much, due to wind resource good where be all often ungetable mountain area and Marine shoal
Deng, so the installation of wind power tower and to transport not only extremely difficult but also cost very high, to mounting technique and transport capacity all
Propose higher requirement.
Utility model content
This utility model aims to solve the problem that the problems referred to above, there is provided new bending and molding multiple combined-type wind power tower, and which leads to
Cross the size for reducing cylinder, cylinder is readily transported and machining so that wind power tower in batch, standardized production become existing
Real, by arranging, in cylinder, the torsional rigidity that annular gusset improves overall pylon, increased and cylinder by modular flange
The solder bond face of body, improves intensity and the safety of pylon, overcomes the weld defect of traditional welding operation；Whole pylon
Thick, the heavy structure of conventional tower is changed, conveniently transport and installation, larger reduces cost of transportation and installation cost,
Guarantor of the wind-powered electricity generation construction there is provided feasibility that be abundant to wind resource but being inconvenient to transport the ground such as mountain area, island and the beach of installation
Barrier, practical；The technical scheme which adopts is as follows：
New bending and molding multiple combined-type wind power tower, including several cylinders, the cylinder is by least three blocks steel plates
It is spliced after bending, the cylinder medial wall is provided with for strengthening the annular gusset of cylinder torsional rigidity, the cylinder
Two ends be provided with modular flange, the modular flange is made up of at least two-layered steel plates, and described two cylinders head and the tail connect
Connect, the modular flange of described two barrel ends is bolted with spacer flanger.
On the basis of above-mentioned technical proposal, between the two-layered steel plates of the modular flange, be provided with reinforcement, described plus
Strong muscle and steel plate welding, the modular flange and barrel soldering.
On the basis of above-mentioned technical proposal, bolt is stated using high strength anti-loose bolt.
On the basis of above-mentioned technical proposal, the plating zinc on surface of the cylinder, modular flange, spacer flanger and bolt or
Coating overcoat.
This utility model has the advantage that：Which passes through the size for reducing cylinder, cylinder is readily transported and machining,
So that wind power tower in batch, standardized production become a reality, by cylinder arrange annular gusset improve overall pylon
Torsional rigidity, increased the solder bond face with cylinder by modular flange, improve intensity and the safety of pylon, gram
The weld defect of traditional welding operation is taken；Whole pylon changes thick, the heavy structure of conventional tower, conveniently transport and peace
Dress, larger reduces cost of transportation and installation cost, to wind resource abundant but be inconvenient to transport the mountain area of installation, island and
The wind-powered electricity generation construction on the ground such as beach provides the guarantee of feasibility, practical.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in Figures 1 to 5, the new bending and molding multiple combined-type wind power tower of the present embodiment, including several cylinders
Body 1, by being spliced after at least three pieces steel plate 1-1 bendings, 1 medial wall of the cylinder is provided with for strengthening cylinder the cylinder 1
The annular gusset 2 of body torsional rigidity, the two ends of the cylinder 1 are provided with modular flange 3, the modular flange 3 by
At least two-layered steel plates are constituted, and 1 head and the tail of described two cylinders connect, the modular flange 3 and intermediate method of 1 end of described two cylinders
Blue 4 are connected by bolt 5.Whole pylon is made up of cylinder, and single barrel space small volume, piece weight are little, is easy to lifting to pacify
Dress.
The steel plate burst of composition cylinder is generally equilateral polygon decile, and special circumstances can also be made equilateral
Polygon takes decile；Should be equilateral polygon cylinder or cone after combination.The cylinder can be made annealing treatment, it is possible to
Galvanizing or coating preservative treatment are done as needed.
The annular gusset not only can strengthen the strength and stiffness of main body, can also keep and improve main body and two
The linearity on connection side.
Preferably, reinforcement 3-1 is provided between the two-layered steel plates of the modular flange 3.
Modular flange, with the reasonability on structural mechanics, thus also relatively reduces the consumption of steel, has using section
Can consumption reduction；Modular flange by two layering steel plates respectively with barrel soldering, increased the welding of entire combination flange and cylinder
Faying face, the single butt-welded connected mode that the conventional flange of changing over is connected with tower, safety coefficient can be at double
Improve, safety has great guarantee；Modular flange adopts common flaw detection steel plate, than in the past using traditional ring-like forging method
Orchid also has very big raising on economic index.
Preferably, the bolt adopts high strength anti-loose bolt；Bolt is inside tower.
Further, the plating zinc on surface of the cylinder 1, modular flange 3, spacer flanger 4 and bolt or coating overcoat.
The top flange of pylon can need to make suitable adpting flange according to the connection of blower fan；The bottom of pylon can be with
Connection according to foundation needs to make suitable adpting flange.
By way of multiple cylinders connect, the tower of original large round size is exponentially reduced, is greatly facilitated
Handling and installation, can also carry out postwelding stress relief annealing, effectively eliminate welding stress and local concentrated stress, improve
The fatigue resistance of tower and life-span, unpredictable risk is significantly reduced, is contributed in safety very big；Annular is set in cylinder
Gusset improves the bulk strength of overall pylon and rigidity, has been improved particularly the anti-torsional strength and rigidity of overall tower, has made tower
The stability of the safety of frame structure and anti-strong wind is improved.
By way of example this utility model is illustrated above, but this utility model is not limited to above-mentioned being embodied as
Example, all any changes that is done based on this utility model or modification belong to the claimed scope of this utility model.
