The invention discloses a wind turbine tower cylinder shock absorber structure which mainly comprises a ring-shaped inflating airbag, a tempering damper, a lightning arrester and the like. When hoisting operation of a wind turbine generator is not completed, needs to be stopped temporarily, and waits for the later-period suitable installing opportunity, a shock absorber is hoisted and connected toa tower cylinder flange, during working of the shock absorber, the damper adjusts the state of itself according to the incoming flow situation, and it is ensured that the deformation amount of the tower cylinder is controlled within a reasonable range. Meanwhile, the ring-shaped inflating airbag can be adjusted according to change of the wind direction of incoming flow, thus intensity of fallingvortex generated behind the tower cylinder when airflow goes bypass the tower cylinder is weakened, then wind resistance borne by the tower cylinder is reduced, and the situation that the tower cylinder generates violent vibration is avoided. When the next suitable installing opportunity comes, the shock absorber is disassembled to be used next time. The structure can effectively weaken vibrationgenerated on the tower cylinder by the effect of outside wind, safety during the installing stasis period of the wind turbine generator is ensured, and the structure has the advantages of being simpleand rapid in implementation of practical engineering.
