Problems solved by technology

However, the disadvantage of the rubber isolation bearing is that it does not have a shock-absorbing function in the vertical direction. From the seismic records measured by previous major earthquakes, the vertical earthquake occupies a lot of weight in the entire seismic energy. How to solve the problem of vertical vibration of the storage tank Seismic isolation has always been a difficult problem in the field of seismic isolation

Abstract

The invention relates to the technical field of lifeline engineering, in particular to a vertical shock-absorption damper device used for a storage tank. The vertical shock-absorption damper device used for the storage tank comprises a storage tank cylinder used for storing liquid, a connecting plate, a lower support, a rotary blade and a ball screw. When a vertical earthquake happens, the storagetank cylinder and the connecting plate drive an outer nut on the ball screw to move vertically; due to the fact that the vertical displacement of the ball screw is restrained by the lower support, balls of the ball screw rotate in the axial direction to drive the rotary blade on the ball screw to rotate; the blade is damped by the liquid stored in the storage tank cylinder, and damping generatedby the rotation of the blade is converted into vertical damping by the ball screw, so that a shock-absorption effect is achieved, damage, caused by the vertical earthquake, to the storage tank cylinder is reduced, and further explosions, fires and environmental pollution are prevented; and the vertical shock-absorption damper device is simple and easy to manufacture and does not need to be specially maintained.

Description

technical field [0001] The invention relates to the technical field of lifeline engineering, in particular to a vertical shock absorbing damper device for storage tanks. Background technique [0002] A large destructive earthquake, if it occurs in a densely populated and economically developed area or city, will kill thousands of people in tens of seconds or even a few seconds, and hundreds of thousands of buildings will be destroyed. (Structure) buildings were reduced to ruins, causing huge disasters to mankind. As for the extra-large LNG storage tank as a lifeline project, the storage tank itself is very vulnerable to earthquakes. Earthquakes not only lead to the loss of its use function, but also easily cause explosions, fires and environmental pollution, which in turn lead to catastrophic consequences. The loss caused by these storage tanks will far exceed the economic value of the storage tank itself and the storage liquid itself. [0003] In order to reduce the impac...
