Description
Technical field
The present invention relates to a kind of water-tight corrosion-proof anchor structure for blower foundation.
Background technology
Being dispersed with the various water systems such as size, rivers different in size, lake at home, up to the present, wind energy turbine set is divided into
Land and marine wind electric field two types, the wind field wherein set up in the landform such as mountain region, Plain, rivers and desert is the most land
The wind field built on wind energy turbine set, Intertidal zone and ocean is referred to as marine wind electric field, according to national policy, the mark post electricity of marine wind electric field
Valency is more much higher than the electricity price of land wind energy turbine set.So, when carrying out the construction of wind energy turbine set, the wind energy turbine set being positioned on rivers and lakes
The form of construction work being difficult to be considered as marine wind electric field is built, thus exists and be difficult to basis end face is raised to more than the water surface
Situation, crab-bolt (or anchor pole) and assembly thereof will have to the long period of soaking in the face of water.Anchoring assembly of the prior art be
One layer of anticorrosive coat is plated, it is achieved corrosion is avoided in the isolation with water on anchoring assembly.But anticorrosive coat once suffers brokenly ring, whole anchoring
Assembly is just highly susceptible to corrode, and affects the safe operation of blower fan.Therefore, need to carry except the water resistance of anchoring assembly itself
Outside Shenging, with anchoring assembly with the use of structure be also required to preferable water resistance.
Summary of the invention
Present invention solves the technical problem that and be, it is ensured that anchor pole and assembly thereof be not in the case of being had by water logging for a long time, the most not
Occur or occur that few water yield penetrates into crab-bolt body, thus do not occur or less corrosion occurs, it is ensured that blower fan
Safe operation.
The technical scheme is that, it is provided that a kind of water-tight corrosion-proof anchor structure for blower foundation, at blower foundation
Important actor body on water-tight corrosion-proof anchor structure is set, water-tight corrosion-proof anchor structure include anchoring assembly, anchoring assembly include anchor pole,
The part to be tightened that is enclosed within anchor pole and for fixing the nut of part to be tightened, the outer surface of described anchor pole and part to be tightened is all coated with
Zinc-chromium coating, the outer surface of described nut is had to be coated with zinc layers.
Further, being provided with pad between described nut and part to be tightened, the outer surface of described pad is coated with zinc layers.
Further, described anchoring assembly includes wrapping up anchor pole end and the protection set of nut, fills weather-proof in protection set
Silica gel.
Further, the periphery at anchoring assembly sets Colophonium overcoat.
Further, the periphery at Colophonium overcoat is provided with concrete guardrail.
Further, the upper surface at anchor slab is provided with the groove around anchor pole, fills weather-proof silica gel in groove.
Further, described groove is circular, and the cross section of groove is circular arc, and the quantity of described groove is 2-4 circle.
Further, the lower surface at anchor slab is provided with the water fender around anchor pole.
Further, described water fender for cylindrical shape, the quantity of water fender is 1-3.
Further, the thickness of described zinc-chromium coating is 9.8-10.2 μm, and the thickness of described zinc layers is 78-82 μm.
(anchor slab and the structural connection of large-size that is enclosed within anchor pole are (such as method at anchor pole and part to be tightened for the present invention
Blue)) use Dacroment to process so that one layer of zinc-chromium coating of its surface attachment；Nut, pad and other small parts use hot dipping
The mode of zinc processes so that it is one layer of zinc layers of surface attachment.Zinc-chromium coating and zinc layers can completely cut off contacting of anchoring assembly and water.
Zinc-chromium coating is not only possible to prevent corrosion, it is thus also avoided that be difficult to anchor pole and the problem of anchor slab generation hydrogen embrittlement changed.Nut, pad
The zinc layers adhered to Deng the outside of small parts not only can be waterproof, but also achieves the anodic protection of anchoring assembly, extends
In the service life of anchoring assembly, small parts is readily replaceable, and cost is relatively low, can protect anchor pole and part to be tightened etc. well
It is difficult to dismantle or non-detachable parts are from corrosion.On the one hand the thickness of corrosion-inhibiting coating must is fulfilled for state compulsory standard
Requirement, on the other hand, also gives crab-bolt and assembly thereof from dispatch from the factory, transport, load and unload and collide work progress or rub
Loss is occurred to leave certain surplus.The grade of the Dacromet/steel required in this technique is 4 grades, red rust occurs through salt spray test
Time be not less than 1000h, Hot-dip Galvanizing Coating requires to occur without white product in salt spray test in 96h.The anchoring of the present invention
The time of the mixed coating salt-fog resistant test of assembly reaches more than 1200h.
The present invention is provided with concrete guardrail in the outermost of anchoring assembly, be possible to prevent various in the natural environment such as ocean outside
The power destruction to anchoring assembly, concrete is preferably provided with higher density simultaneously, improves water resistance, inside concrete guardrail
Being additionally provided with joint bar, different from the reinforcing bar in concrete, joint bar one end is inside concrete guardrail, and the other end is fixed on matrix,
The effect of reinforcing can be played.
The inner side of concrete guardrail is Colophonium overcoat, and Colophonium itself has preferable water resistance, is also easy to execute simultaneously
Work, mobility is preferable, and hardware can play after solidification good waterproof action.Colophonium overcoat is located at whole anchor
Gu the periphery of assembly, form one and seal structure.Further, since Colophonium is the material of relative flexibility, between Colophonium and concrete
Joint face do not have gap yet, can be the most waterproof.
The present invention is at the groove of the upper surface setting of anchor slab, and for filling the weather-proof silica gel of excess, the top of anchor slab can set
Have connector (such as flange) due to flange and anchor slab be all metalwork (anchor slab and connector as an entirety, its upper and lower both sides
It is equipped with nut, so anchor slab and connector are properly termed as part to be tightened), easily form gap between two metalworks, in order to
Avoid affecting the structure of flange, the present invention select the upper surface of anchor slab arrange in order to the groove sealed, preferably set multi-turn recessed
Groove, thus can form the waterproof effect of multilamellar, the weather-proof silicone filler of excess so that the density of groove greatly
Improve.Gap between anchor slab and the part to be tightened above it can filling with sealant, for waterproof.
Water fender at the lower surface design of anchor slab is the seepage paths for extending water, owing to the lower section of anchor slab is back-grouting
Body-concrete, water fender is in concrete, and concrete itself has certain waterproof action, can be further in conjunction with water fender
Ground extends the water penetration time to anchor pole.Dash copper sheet typically selected by water fender, is welded on the lower surface of anchor slab, and such water just must
Water fender must be walked around and can be only achieved bolt body.
The invention has the beneficial effects as follows, the different parts of anchoring assembly use different anticorrosive coats, at anchoring assembly
Periphery be provided with the waterproof construction of multi-form and realize multiple effect waterproof, etch-proof, substantially increase anchoring assembly self
Antiseptic power；Replace the gap of grease-filled anchoring assembly simultaneously with weather-proof silica gel, waterproof, antiseptic effect can be improved, with
Time also can avoid initial ring environment pollution.
