Tuned liquid damper

The utility model relates to a tuned liquid damper which is suitable for the field of vibration control of engineering structures. The tuning liquid column damper is wide in vibration attenuation frequency band, remarkable in energy consumption effect, low in manufacturing and maintenance cost and small in installation space. According to the technical scheme, the damper is provided with a U-shaped pipe, and a throttling adjusting mechanism is installed in the horizontal section of the U-shaped pipe. The throttling adjusting mechanism is provided with a check block fixedly installed in the horizontal section U-shaped pipe, the check block is provided with a plurality of first throttling holes formed in the through length direction of the horizontal section U-shaped pipe, and the side face, making contact with the inner wall of the horizontal section U-shaped pipe, of the check block is provided with an installation groove formed in the section of the horizontal section U-shaped pipe.
