Description
Technical Field
The application relates to the technical field of tuned liquid dampers, in particular to a liquid level stabilizing and water supplementing system of a tuned liquid damper.
Background
Fire fighting water boxes are often required at the top of high-rise buildings. Under the action of wind load, the high-rise building is in a vibration state throughout the year, and the maximum vibration of the high-rise building is positioned on the roof of the structure. Through reasonable design, can set up fire hose into reasonable water tank size to reserve the interior liquid space of rocking of water tank and increase the measure that improves damping, can make the free vibration frequency of water tank the same with the self-oscillation frequency of major structure, will reform transform into Tuning Liquid Damper (TLD) simultaneously with roof fire hose. When the top of the structure is in a shaking state, the roof water tank is in an opposite shaking state, and meanwhile, due to the arrangement of the device for improving the liquid shaking damping, the shaking energy of liquid in the water tank can be rapidly absorbed by the water tank in a shaking mode, so that the purpose of reducing the shaking of the structure is achieved. The system is a Tuned Liquid Damper (TLD) system.
In tuned liquid damper system designs, the depth of the liquid in the tank can affect the sloshing frequency of the liquid, thereby affecting the damping efficiency of the system. The nth order sloshing frequency of the liquid in the water tank can be calculated approximately as follows:
wherein H is the liquid level height of the liquid still, a is half of the length of the water tank in the shaking direction, and according to the formula, when the length of the water tank is fixed, the shaking frequency of the water tank is approximately proportional to the root number of the water depth. When the actual water depth deviates from the designed water depth in the use process, the shaking frequency of the tuned liquid damper deviates from the preset shaking frequency. After the shaking frequency of the tuned liquid damper deviates from the shaking frequency of the main body structure, the vibration reduction efficiency of the tuned liquid damper is reduced, and even negative vibration reduction effects occur.
The conventional fire-fighting water tank is shown in fig. 1, and is generally composed of a water inlet pipe, a water outlet pipe, an overflow pipe, a liquid level height judging device and a water inlet control valve. The common liquid level height judging device adopts a floating ball or a pressure valve, and when the water level height is lower than a preset target water level, water is supplemented until the target water level is reached. When the water level is too high and exceeds the overflow pipe control water level, the liquid in the water tank flows out from the overflow pipe.
And a damper tank for a tuned liquid damper installed on a high-rise building is shown in fig. 2. Because the effects of larger liquid shaking space and frequency modulation resonance are reserved, in the normal use state of the building, the liquid in the water tank is in a shaking state all the year round. When the swaying trough is positioned at the water level judging position, the water tank can be filled with water, so that the water level exceeds the target design water level. The water inlet control devices commonly used in fire fighting water tanks are therefore often not employed in tuned liquid dampers. And a set of BAS (building equipment automation) system is needed, and the BAS system needs to comprehensively judge whether water can be replenished into the water tank and when to stop after integrating the vibration amplitude of the roof, the shaking condition of the water level and the current water level. When the BAS system judges that the current water level and the water depth are insufficient and water is needed to be replenished, the water level shaking wave height of the liquid and the current floor vibration acceleration are further judged, so that the fact that the current liquid is not in a shaking state and the larger liquid level shaking is unlikely to occur in a future period of time is determined, and water replenishing can be carried out. The whole water replenishing system needs a computer analysis logic judgment unit.
Because of the nature of tuned liquid dampers, the liquid in the tank is typically in sloshing, and in order to improve the control, it is necessary to ensure that the liquid in the tank reaches the target level. This results in the necessity of introducing complex water level monitoring systems, acceleration systems and control systems into the control systems of existing tuned liquid dampers. The system is used for judging whether the liquid in the water tank is in a shaking state or not and whether the liquid is in a shaking state or not, and only when the liquid in the water tank is not large in shaking amplitude and the water tank is in an underwater state, water can be supplemented. This results in some drawbacks:
1) The water can be supplemented only in a static state, and when the water shortage state is in a windy weather, the structure cannot be supplemented when shaking severely, so that the stability of the system is limited;
2) The data identification of whether water can be replenished is derived from a plurality of position water level monitoring and acceleration monitoring electrical signals, and a control system is still required to carry out logic judgment. The system belongs to an active control system, and for the whole set of system, the system needs to maintain the electric stability of the control system, the data acquisition is accurate, and the system is judged to be stable, so that higher requirements are provided for the maintenance of the system;
3) The system judges that water is replenished under small interference, but the system always has the condition of small vibration interference due to continuous shaking of the building, so that the liquid is in an excessive replenishment state, and the efficiency of the system is affected.
