Abstract

The utility model relates to a foundation ring damping device for a MW wind turbine generator system. The damping device is characterized in that a foundation ring (1) and foamed rubber sponge strip rings (2) are included, wherein the foamed rubber sponge strip rings (2) are adhered to the inner wall and the outer wall of the foundation ring (1); and the adhesion positions of the foamed rubber sponge strip rings (2) are within a 300 plus or minus 100 mm transition section of the foundation ring (1) embedded in reinforced concrete (5) under the ground level (4). The foamed rubber sponge strip rings are adhered to the inner and the outer walls of the foundation ring to generate expansion allowance between the foundation ring and the reinforced concrete, so that the free solidification of the reinforced concrete causes no influence on the foundation ring; and the foamed rubber sponge strip rings are adhered to the foundation ring in the positions within the 300 plus or minus 100 mm transition section embedded in the foundation reinforced concrete under the ground level, so as to play an important role in guaranteeing the safety of a tower.

Description

MW class wind turbine group foundation ring damping device

(1) technical field

The utility model relates to a kind of MW class wind turbine group foundation ring damping device, belongs to the wind power generating set equipment technical field.

(2) background technique

The MW class wind turbine group is supported on high aerial by towering tower tube, the foundation ring under the tower tube bears huge vertical pressure and side direction moment of flexure.

Foundation ring is cast in the Steel Fabric Reinforcement concrete, finds in the practice that concrete can produce thermal expansion in curing.The thermal expansion coefficient of concrete and foundation ring is different, causes the foundation ring flange to become cambered surface easily, and can not satisfy installation requirement, causes enormous economic loss.

Have, towering tower tube also can ceaselessly rock under wind-force effect and stratum vibrations again.If tower tube ground (foundation ring and concrete) all rigidity contacts, also with very fast generation shearing force, to quicken fatigue crack to occur, consequence is hardly imaginable.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of MW class wind turbine group foundation ring damping device with certain expansion space, good damping effect is provided.

The purpose of this utility model is achieved in that a kind of MW class wind turbine group foundation ring damping device, it is characterized in that it comprises foundation ring and bipeltate sponge strip ring, and described bipeltate sponge strip ring is bonded on the foundation ring inside and outside wall.

The utility model MW class wind turbine group foundation ring damping device, described bipeltate sponge strip ring bond locations are that foundation ring is imbedded under the ground level in the reinforced concrete on 300 ± 100mm scope changeover portion.

The utility model MW class wind turbine group foundation ring damping device behind bonding bipeltate sponge strip ring on the foundation ring inside and outside wall, has had expansion space between foundation ring and the concrete, and concrete can freely solidify, and can not have any impact to foundation ring.Imbed under the ground level in the reinforced concrete bonding bipeltate sponge strip ring on 300 ± 100mm scope changeover portion at foundation ring, play important effect guaranteeing tower tube safety.
