The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In order to meet the requirement that the structure and equipment of a nuclear power station are not allowed to be damaged by earthquake, the structural characteristics of the nuclear power station of a double-containment (an outer containment 12 and an inner containment 11) are exerted according to the actual condition of earthquake three-dimensional vibration (two horizontal directions and one vertical direction). A base isolation and three-dimensional shock absorption structure 100 for a double containment nuclear power plant according to an embodiment of the present invention will be described with reference to fig. 1 to 3.
As shown in fig. 1 to 3, a base-isolation and three-dimensional shock-absorption structure 100 for a double containment nuclear power plant according to an embodiment of the present invention includes: the device comprises an inner containment vessel 11, an outer containment vessel 12, a horizontal vibration isolation support 21, a vertical vibration isolation support 22, a vertical damper 23 and a connecting rod sliding block mechanism 66.
As shown in fig. 1 and 3, the outer containment vessel 12 is connected with the foundation 400 in a fixed connection manner, the outer containment vessel 12 covers the inner containment vessel 11, the inner containment vessel 11 abandons the traditional fixed connection manner and is installed on a horizontal shock isolation support 21, the horizontal shock isolation support 21 adopts a rubber shock isolation support as a shock isolation layer, the horizontal shock isolation support 21 is installed on the foundation 400, and the horizontal stiffness of the horizontal shock isolation support 21 is smaller than the vertical stiffness, so that the stiffness of the horizontal connection between the inner containment vessel 11 and the foundation 400 is smaller, the inner containment vessel 11 can move relative to the foundation 400 in the horizontal direction during an earthquake, and a larger horizontal relative displacement between the inner containment vessel 11 and the outer containment vessel 12 is formed. The outer containment vessel 12 has a large structural rigidity, so the earthquake horizontal displacement is small, while the inner containment vessel 11 has a small structural rigidity, so the inner containment vessel 11 and the outer containment vessel 12 can generate a large horizontal displacement difference. Specifically, the inner containment 11 and the internal structure thereof adopt a horizontal seismic isolation support 21 for base isolation, and the transmission energy of horizontal seismic motion to the nuclear power plant structure and equipment is isolated.
Specifically, the horizontal shock-insulation support 21 can disperse, weaken and channel the earthquake acting force in a mode that the inner containment vessel 11 vibrates along the horizontal direction relative to the foundation 400, at the moment, the earthquake response of the horizontal shock-insulation support 21 is mainly concentrated on a basic shock-insulation layer, so that the horizontal earthquake motion can be isolated, and the horizontal earthquake motion of the inner containment vessel 11 and the internal structure thereof is reduced.
As shown in fig. 1 to 3, a plurality of link and slider mechanisms 66 are arranged between the inner containment vessel 11 and the outer containment vessel 12, and the plurality of link and slider mechanisms 66 are arranged at intervals along the circumferential direction of the inner containment vessel 11.
In some embodiments, the link-slider mechanism 66 further comprises: the first slide block 61, the first slide way 62, the first connecting rod 63 and the second connecting rod 64, the first end of the first connecting rod 63 is connected with the inner containment vessel 11, the second end of the first connecting rod 63 is hinged with the first end of the first slide block 61, the first slide way 62 extends along the horizontal direction, the first slide block 61 is in sliding fit with the first slide way 62, the second end of the first slide block 61 is hinged with the first end of the second connecting rod 64, the second end of the second connecting rod 64 is hinged with the damping slide block 24, the damping slide block 24 is in sliding damping fit with the outer containment vessel 12 along the vertical direction, and when the first slide block 61 moves along the horizontal direction, the damping slide block 24 is driven to slide relative to the outer containment vessel 12 along the vertical direction.
Therefore, when the inner containment vessel 11 moves in the horizontal direction relative to the foundation 400, the first connecting rod 6352 is driven to move in the horizontal direction, and then the first sliding block 61 moves in the extending direction of the first sliding way 62, the damping sliding block 24 moves in the vertical direction relative to the outer containment vessel 12 through the second connecting rod 64, a vertical friction damping force is formed through the vertical movement, and then the horizontal movement of the inner containment vessel 11 is converted into the vertical movement of the damping sliding block 24, that is, the horizontal movement of the inner containment vessel 11 is converted into the vertical damping of the outer containment vessel 12, so that the vertical vibration of the inner containment vessel 11 and the internal structure thereof is reduced.
The inner wall of the outer containment vessel 12 is provided with a vertical sliding groove 121, and the damping sliding block 24 is mounted in the sliding groove 121, so that the sliding fit of the damping sliding block 24 relative to the outer containment vessel 12 can be realized through the matching of the sliding groove 121 and the damping sliding block 24, and the matching structure is simple and high in reliability, so that the performance of the connecting rod sliding block mechanism 66 is improved. Anti-slip patterns can be arranged on the contact surface of the sliding groove 121 and the damping slider 24, or anti-slip coatings can be arranged on the contact surface of the sliding groove 121 and the damping slider 24 to enhance the sliding friction force between the sliding groove 121 and the damping slider 24, so that the sliding damping matching between the damping slider 24 and the outer containment 12 is realized.
In some embodiments, the first slide 61 is provided with a first displacement sensor 31, the damping slide 24 is provided with a second displacement sensor 32; the first slide block 61 is provided with a first temperature sensor 33, the damping slide block 24 is provided with a second temperature sensor 34, and the first displacement sensor 31, the second displacement sensor 32, the first temperature sensor 33 and the second temperature sensor 34 monitor the displacement and the ambient temperature of the connecting rod slide block mechanism 66 in real time. .
As shown in fig. 1 and 3, the base shock insulation and three-dimensional shock absorption structure 100 for the double-containment nuclear power plant further includes: the inner containment bottom plate 13, the vertical vibration isolation support 22 and the vertical damper 23.
The arrangement of the inner containment vessel bottom plate 13 realizes that the inner containment vessel 11 is installed on the horizontal shock insulation support 21, and the horizontal rigidity of the vertical shock insulation support 22 is greater than the vertical rigidity, so that the vertical shock insulation of the inner containment vessel 11 is realized, and the vertical shock of the inner containment vessel 11 is further reduced; the vertical damper 23 may prevent a collision or the like caused by a relative displacement in a horizontal direction between the core support structure 200 and the inner containment 11, limit an earthquake reaction, and thus protect the core structure 300 connected to the core support structure 200.
In some embodiments, as shown in fig. 1, the inner containment vessel 11 includes a shell body 111, and the first link 63 is connected to an upper end of the shell body 111, and when an earthquake occurs, the first link 63 is connected to the upper end of the shell body 111, so that the link slider mechanism 66 absorbs horizontal vibration of the inner containment vessel 11, thereby reducing the horizontal vibration of the inner containment vessel 11.
In other embodiments, as shown in fig. 3, the inner containment vessel 11 includes a shell body 111 and a tuned mass damper 112, the tuned mass damper 112 is mounted on the top end of the shell body 111, the link slider mechanism 66 is connected to the tuned mass damper 112, and in the event of an earthquake, the tuned mass damper can provide a force with a frequency almost equal to and opposite to the direction of the structure movement to partially cancel the structure response caused by the external excitation, so that the tuned mass damper can provide a force with an opposite direction to the inner containment vessel 11 to cancel the horizontal displacement of a part of the inner containment vessel 11, and the link slider mechanism 66 is connected to the tuned mass damper 112, so that the link slider mechanism 66 absorbs the horizontal vibration of the tuned mass damper 112 to further reduce the horizontal vibration of the inner containment vessel 11.
In some examples, tuned mass damper 112 may be a water tank containing water that may be shaken in the water tank by the horizontal vibration of inner containment vessel 11 when an earthquake occurs, but due to the inertia of the water, the water in the water tank may provide a force that is approximately equal in frequency to the horizontal movement of inner containment vessel 11 and opposite in direction to the movement of inner containment vessel 11, thereby counteracting the shaking force experienced by a portion of inner containment vessel 11.
According to the above description, the basic shock insulation and three-dimensional shock absorption structure 100 used for the double-containment nuclear power station is finally formed, the three-dimensional shock absorption effect is realized through the shock absorption arrangement in the horizontal two directions and the vertical one direction, the special shock-resistant safety requirement of the nuclear power station can be met, and the shock-resistant safety of the nuclear power station structure is remarkably improved.
