Self-reset swinging inner barrel shock absorption water tank

Abstract

The invention provides a self-reset swinging inner barrel shock absorption water tank which comprises a base mounted on a lower support structure, outer barrel walls mounted on the base and inner barrel walls mounted in the outer barrel walls, wherein storage water is mounted between the inner barrel walls and the outer barrel walls; six self-reset swinging bearings are uniformly arranged on the base along each inner barrel wall; each self-reset swinging bearing comprises a lower lug plate mounted on the base via a base embedded part, an upper lug plate connected with the lower lug plate via a bolt and four prestress rods symmetrically arranged between the lower lug plate and the upper lug plate; inner barrel wall embedded parts with the same quantity as that of the self-reset swinging bearings are uniformly arranged at the lower ends of the inner barrel walls; the inner barrel walls are fixedly connected with the corresponding upper lug plates via the inner barrel wall embedded parts; and dampers are further arranged at the upper ends between the inner barrel walls and the outer barrel walls. The water tank has the advantages of stable anti-seismic property, good shock absorption effect, reduced structure cost, factory module production and the like.

Description

technical field [0001] The invention relates to a shock-absorbing water tank, in particular to a shock-absorbing water tank with a self-resetting swing inner cylinder. Background technique [0002] The third-generation nuclear power plants represented by AP1000, ACP1000, CAP1400, etc. generally adopt passive technical routes and design ideas, and the passive containment cooling system (PCCS) is an important content of passive technology. The PCCS system is to apply the gravity of matter, the natural convection and diffusion of fluid and other basic natural laws. In the event of an emergency, without personnel intervention and external energy, the gravity water tank of the cooling reactor building (containment) sprays water and turns the water into steam. Take away the residual heat of the core, thereby ensuring the safety of the nuclear power system. Taking AP1000 as an example, when the accident is minor, the PCCS system adopts the internal natural circulation of the steel...
