Top plate opening liquid injection structure of steel chimney liquid damper

The utility model relates to the technical field of liquid injection structures, in particular to a steel chimney liquid damper top plate opening liquid injection structure which comprises a TLD shell fixedly installed at one end of a steel chimney, a damping liquid cavity is formed in the top end of the TLD shell, and a liquid injection hole is formed in the side, close to the steel chimney, of the damping liquid cavity. According to the utility model, a top plate liquid injection mode is adopted to solve the risk of side face leaning liquid injection, the operability is simplified, a single tank or a plurality of pipes can be designed to be a top plate opening liquid injection mode, but under the condition that the width of a signal lamp platform needs to meet the use requirement, the operation is simple, and the cost is low. The hole opening position is designed, the high-altitude operation danger coefficient is reduced, operation is convenient, and the liquid injection quality is guaranteed. 本实用新型涉及注液结构技术
