AI Technical Summary
Technical Problem
Existing liquid mass tuning dampers require regular addition of damping liquid, and the damping effect is poor, making it difficult to adapt to changes in structural characteristic frequency and load frequency.
Method used
A liquid mass tuning damper for 5G pole towers is designed, using a funnel-shaped cover to collect rainwater, and a swingable metal block and through hole are provided in the reservoir. Double vibration cancellation is used for magnets and spring systems, and the damping effect is ensured through the sliding structure and limit blocks.
Benefits of technology
It realizes the stable damping effect without regular liquid replenishment, adapts to changes in structural characteristic frequency and load frequency, and improves wind and earthquake resistance.

Abstract
The invention discloses a tuned liquid mass damper for a 5G tower, and belongs to the technical field of structural vibration control. The problems that damping liquid needs to be added regularly and the damping effect is poor in an existing liquid mass tuned damper are solved. The small opening end of a funnel-shaped cover body corresponds to the middle of an outer box body, the lower surface of the extension of the funnel-shaped cover body is fixedly connected with the upper end opening of the outer box body, and the small opening end of the funnel-shaped cover body is located on the upper side of the upper end opening of a liquid storage box; two mutually perpendicular sliding ways are arranged on the bottom face in the outer box body, one sliding way is located on the other sliding way, the liquid storage box slides on the sliding way on the upper side, four damping springs are arranged between the liquid storage box and the outer box body, the two ends of each damping spring are located in the center of the liquid storage box and the center of the four side faces of the outer box body respectively, and the two ends of each damping spring are located in the middle of the liquid storage box. The upper end of the metal block is hung in the liquid storage tank through a hanging line and a cross rod, and liquid is arranged in the liquid storage tank. The vibration damper is suitable for vibration damping.
