Floating type dynamic self-balancing liquid sloshing resisting device of liquid storage tank

Abstract

The invention discloses a floating type dynamic self-balancing liquid sloshing resisting device of a liquid storage tank, which comprises a buoyancy tank, a power transmission column and a sloshing resisting partition board. The upper end of the power transmission column is fixedly connected with the buoyancy tank, and the lower end of the power transmission column is fixedly connected with the sloshing resisting partition board. During usage, the floating type dynamic self-balancing liquid sloshing resisting device is assembled in a liquid storage tank such as a middle or large-sized vertical liquid storage tank, and realizes a relieving effect to sloshing of liquid in the liquid storage tank by the aid of self inertial resistance of the device and dynamic self-balancing of buoyancy. Thefloating type dynamic self-balancing liquid sloshing resisting device has the advantages that the floating type dynamic self-balancing liquid sloshing resisting device is simple in manufacture and convenient in installation, an effective resistance effect is realized for sloshing of convection current mass in the liquid is directly realized, measures are efficient, direct and remarkable, and the like.

Description

technical field [0001] The invention relates to a liquid storage tank anti-sloshing device, in particular to a floating dynamic self-balancing liquid storage tank anti-sloshing device. Background technique [0002] At present, in the field of petrochemical and transportation reserve engineering, in order to reduce the sloshing of liquid in large and medium-sized vertical liquid storage tanks under the action of earthquakes, it is mainly done from the outside of the liquid storage tank, and the vertical liquid storage tank and the foundation Vibration isolation columns or lead-core rubber isolation bearings are set up between them to reduce the excitation of seismic waves, thereby reducing the input of the bottom of the storage tank into the liquid storage tank-tank liquid system. Seismic excitation. Although the seismic wave excitation amplitude can be reduced to a certain extent, there is no restraint coupling between the tank body and the tank liquid in the liquid storage...

AI Technical Summary

Problems solved by technology

Although the seismic wave excitation amplitude can be reduced to a certain extent, there is no restraint coupling between the tank body and the tank liquid in the liquid storage tank, and the effect is indirect.

In addition, when installing the vibration isolation columns and rubber bearings, it is necessary to overhead the storage tank. Due to the local stress concentration at the bottom of the tank, this has limitations on the strength of the tank bottom material and the volume of the tank body.
