Embodiment 1

[0035] Embodiment 1 of the present invention provides a method for anti-corrosion of wind turbine base, the schematic diagram of which is as follows figure 2 As shown, the method includes:

[0036] Step 1. Apply a neutral weather-resistant sealant to the lower edge of the sealing cap.

[0037] Step 2. Tighten the sealing cap and the anchor bolts so that the lower edge of the sealing cap fits the backing plate flange.

[0038] The fit between the lower edge of the sealing cap and the backing plate flange refers to: the neutral weather-resistant sealant applied on the lower edge of the sealing cap fills the gap between the lower edge of the sealing cap and the backing plate flange to achieve sealing The sealing effect between the lower edge of the cap and the flange of the backing plate.

[0039] The sealing cap is a cover made of rubber. The sealing cap should be able to cover the exposed part of the anchor bolts on the ground, and can be closely matched with the anchor bolt...

Embodiment 2

[0046] Figure 4 It is a schematic diagram of the anti-corrosion method for the wind turbine base provided by the second embodiment of the present invention. Embodiment 2 of the present invention is based on the technical solution of Embodiment 1. Preferably, before step 1, it also includes:

[0047] Step 11. Apply waterproof material on the anchor bolts and nuts.

[0048] The waterproof material can be butter or rubber waterproof material. In order to achieve a long-term anti-corrosion effect, after the four times of reapplying the pre-tightening force, the waterproof material can be applied to the anchor bolts and nuts.

[0049] Furthermore, after step 3, it may also include:

[0050] Step 31, painting waterproof paint on the tower flange, backing plate flange and concrete base.

[0051] The waterproof coating applied in step 31 is a rubber-based waterproof coating.

[0052] After step 31, may also include:

[0053] Step 32, setting a waterproof protective layer on the...

Embodiment 3

[0057] Figure 5 The schematic diagram of the base of the wind power generator provided by Embodiment 3 of the present invention is combined below Figure 5 This embodiment will be described in detail. Embodiment 3 of the present invention provides a wind power generator base, including a concrete base 4, anchor bolts 5, nuts 6 and backing plate flange 2, which also includes a sealing cap 7 and a neutral weather-resistant sealant 8, the sealing cap 7 and the anchor bolts 5 are tightened, and the neutral weather-resistant sealant 8 is arranged on the lower edge of the sealing cap 7 so that the lower edge of the sealing cap 7 fits between the backing plate flange 2 .

[0058] On the basis of the above-mentioned technical solutions, it is preferred that the wind-driven generator base also includes a waterproof material layer (not shown) and a waterproof coating layer 9, and the waterproof material layer is arranged on the outside of the anchor bolts 5 and the nuts 6; the waterpr...

Abstract

The invention discloses an anti-corrosion method for a wind driven generator base and the wind driven generator base. The anti-corrosion method for the wind driven generator base comprises the following steps of: coating neutral weather-resistant sealant at the lower edge of a sealing cap; tightening the sealing cap with an anchor bolt by a bolt to enable the lower edge of the sealing cap to be clung to a base plate flange; and coating the neutral weather-resistant sealant at an internal corner position where a tower tube flange contacts with the base plate flange as well as the internal corner position where the base plate flange contacts with a grouting layer. The anti-corrosion method for the wind driven generator base and the wind driven generator base provided by the invention are reliable in an anti-corrosion effect.

Description

technical field [0001] Embodiments of the present invention relate to anti-corrosion technology, in particular to a method for anti-corrosion of a wind power generator base and a wind power generator base. Background technique [0002] The wind turbine base is used for fixed installation of the wind turbine steel tower, which includes a concrete base, a grouting layer, and connectors, and the connectors include anchor bolts, nuts, and backing plate flanges. The fixing method of the wind turbine steel tower is as follows: the tower flange is fixed to the grouting layer and the concrete base through anchor bolts, nuts and backing plate flanges. [0003] figure 1 It is a schematic diagram of the connection between the base of the wind turbine and the steel tower. Combine below figure 1 Describe in detail the fixing method of the steel tower of the wind power generator. The lower part of the tower flange 1 is provided with a backing plate flange 2, and the tower flange 1, the...
