Problems solved by technology

However, the design of the frequency-tuned liquid damper is complicated, and the ability to use the sloshing energy of water is limited. Therefore, this patent combines the tuned mass damper, the tuned liquid damper and the friction damper to make their advantages complementary to form a structure. Simple, low-cost, and powerful new energy-absorbing and vibration-absorbing water tank structure, which has significant significance for the seismic safety of nuclear power plants and large industrial water tanks

Embodiment approach 1

[0024] Embodiment 1: The embedded part provided on the water tank wall refers to the embedded part provided on the inner wall of the water tank or the embedded part provided on the water tank wall refers to the embedded part provided on the outer wall of the water tank. The implementation here is to reserve a certain number of embedded parts 7 on the outer wall 2 or inner wall 3 of the water tank, then weld and install the hinged seat 4, and install the perforated plate 1 on it, and finally install the spring element 5 and the damping element 6 according to the requirements. Install in place.

Embodiment approach 2

[0025] Embodiment 2: When both the inner wall of the water tank and the outer wall of the water tank are provided with embedded parts, the embedded parts on the inner wall of the water tank and the embedded parts on the underwater outer wall are arranged facing each other. This embodiment is to reserve a certain number of embedded parts 7 at the corresponding positions of the outer wall 2 and the inner wall 3 of the water tank, then weld and install the hinged seat 4, and install the perforated plate 1 on it, and finally install the spring element 5 and the damping element 6 according to the requirements in place.

Embodiment approach 3

[0026] Embodiment 3: When both the inner wall of the water tank and the outer wall of the water tank are provided with embedded parts, the embedded parts on the inner wall of the water tank and the embedded parts on the underwater outer wall are arranged alternately. This kind of implementation is to reserve a certain number of embedded parts 7 on the outer wall 2 and the inner wall 3 of the water tank, then weld and install the hinge seat 4, and install the perforated plate 1 on it, and finally install the spring element 5 and the damping element 6 according to the requirements. in place.

[0027] Option 1 is more economical than Option 2 and Option 3, and the installation is more convenient. It has less impact on the volume of the water tank, but the vibration reduction effect is relatively poor. Compared with Scheme 1 and Scheme 3, Scheme 2 has a more stable and excellent vibration reduction effect of the symmetrical installation structure, which has a certain impact on the...

Abstract

The invention provides a swing type porous barrier energy absorption and vibration reduction water tank structure applied to a nuclear power plant shield building. An embedded part is arranged on the wall of a water tank, a hinging base is installed on the embedded part, a porous plate is hinged to the hinging base, dampers and spring elements are symmetrically arranged between the two sides of the porous plate and the wall of the water tank, and the porous plate is located in the water tank. Compared with the prior art, the water tank structure has the advantages that manufacturing cost is low, installation is easy, damping performance is stable, and the existing design of the water tank structure is not changed. The water tank has tremendous advantages in terms of installation and transformation.

Description

technical field [0001] The invention relates to a water tank structure, in particular to an energy-absorbing and vibration-reducing water tank structure with a swinging porous partition applied to a shielding workshop of a nuclear power plant. Background technique [0002] With the improvement of the anti-seismic performance of large industrial storage tanks and nuclear power plants, more and more structures adopt vibration control technology. Structural vibration damping control technology reduces the structural vibration response by setting various components that dissipate vibration energy in the structure and adjusting the structural period. Commonly used dampers are: viscous damper, metal yield damper, friction damper, FM mass damper and FM liquid damper, etc. At present, the commonly used FM mass damper needs to attach an additional mass to the structure. As for the water tank structure, the liquid in the water tank itself can be used as a mass block, and can be desi...
