The receiving space 100 may be a rectangular sealed space. The first partition 211 may be disposed horizontally in the accommodating space, that is, a plane of the first partition 211 is parallel to a horizontal plane. An edge of the first barrier 211 may be connected with an inner wall of the platform 1000, thereby dividing the receiving space 100 into the first cavity 110 and the second cavity 120.
The volumes of the first chamber 110 and the second chamber 120 may be substantially the same, the first chamber 110 may be a rectangular space, and the second chamber 120 may be a rectangular space.
The first stopper 221 is located inside the first cavity 110, and the shape of the first stopper 221 may be a rectangular parallelepiped. The first stopper 221 may divide the first cavity 110 into a first sub-cavity 111 and a second sub-cavity 112. The first stopper 221 is movable in the first direction X, thereby changing the volume of the first and second sub-cavities 111 and 112.
Both ends of the first elastic member 222 are respectively connected to the first stopper 221 and the inner wall of the platform 1000. The extending direction of the first elastic member 222 may be parallel to the first direction X. When an earthquake occurs, the first stopper 221 moves in the first direction X due to inertia, thereby changing the elastic potential energy of the first elastic member 222. The number of the first elastic members 222 may be multiple, and the first elastic members 222 may be located on one side of the first stopper 221, or may be separately located on two sides of the first stopper 221.
The second stopper 231 is located inside the second cavity 120, and the shape of the second stopper 231 may be a rectangular parallelepiped. The second stopper 231 may divide the second cavity 120 into a third sub-cavity 121 and a fourth sub-cavity 122. The second stopper 231 may move in the second direction, thereby changing the volume of the third and fourth sub-cavities 121 and 122.
Both ends of the second elastic member 232 are respectively connected to the second stopper 231 and the inner wall of the platform 1000. The extending direction of the second elastic member 232 may be parallel to the second direction Y. When an earthquake occurs, the second stopper 231 moves in the second direction due to inertia, thereby changing the elastic potential energy of the second elastic member 232. The number of the second elastic members 232 may be multiple, and the second elastic members 232 may be located on one side of the second stopper 231, or may be separately located on two sides of the second stopper 231.
Illustratively, the first elastic member 222 and the second elastic member 232 may be shock-absorbing springs.
In some embodiments, the number of the first elastic members 222 is plural, and the plural first elastic members 222 are respectively disposed at two sides of the first stopper 221; the first elastic members 222 respectively disposed at both sides of the first stopper 221 are symmetrically disposed.
For example, the number of the first elastic members 222 is 8, wherein 4 first elastic members are located on one side of the first stopper 221, and the other 4 first elastic members 222 are located on the other side of the first stopper 221. The 4 first elastic members 222 respectively disposed at both sides of the first stopper 221 are symmetrically disposed.
Similarly, the number of the second elastic members 232 is plural, and the plural second elastic members 232 are respectively disposed at two sides of the second stopper 231; the second elastic members 232 respectively disposed at both sides of the second stopper 231 are symmetrically disposed.
As shown in fig. 4, the first stopper 221 may be formed with a first through hole H1 penetrating the first stopper 221 in the first direction X. The number of the first through holes H1 may be multiple, for example, the number of the first through holes H1 is 8, and the first through holes H1 are arranged in two rows and four columns. The connection position of the first elastic member 222 and the first stopper 221 may be located between two rows of the first through holes H1.
As shown in fig. 5, the second stopper 231 may be opened with a second through hole H2 penetrating the second stopper 231 in the second direction Y. The number of the second through holes H2 may be multiple, for example, the number of the second through holes H2 is 8, and the second through holes H2 are arranged in two rows and four columns. The connection position between the second elastic element 232 and the second stopper 231 may be located between two rows of the second through holes H2.
The first through hole H1 and the second through hole H2 may be circular holes, square holes, elliptical holes, triangular holes, etc., and are not limited thereto.
Viscous liquid 240 is filled in the first sub-chamber 111, the second sub-chamber 112, the third sub-chamber 121, and the fourth sub-chamber 122. During the movement of the first stopper 221, the viscous liquid 240 in the first chamber 110 generates a damping force through the first through hole H1 to dissipate the energy generated by the earthquake. During the movement of the second stopper 231, the viscous liquid 240 in the second chamber 120 generates a damping force through the second through hole H2 to dissipate the energy generated by the earthquake.
The first partition 211 is opened with a third through hole H3. The third through hole H3 communicates the first sub-chamber 111 and the third sub-chamber 121, and in the process of the movement of the first stopper 221 and the second stopper 231, the viscous liquid 240 in the first sub-chamber 111 and the viscous liquid 240 in the third sub-chamber 121 can mutually communicate through the third through hole H3.
The first partition 211 is further provided with a fourth through hole H4. The fourth through hole H4 communicates the second sub-chamber 112 and the fourth sub-chamber 122, and during the movement of the first stopper 221 and the second stopper 231, the viscous liquid 240 in the second sub-chamber 112 and the viscous liquid 240 in the fourth sub-chamber 122 can mutually communicate through the fourth through hole H4.
In this embodiment, the viscous liquid 240 circularly flows in the accommodating space 100 through the first through hole H1, the second through hole H2, the third through hole H3 and the fourth through hole H4, and in the process of moving one of the first stopper 221 and the second stopper 231, the viscous liquid 240 can drive the other one of the first stopper 221 and the second stopper 231 to synchronously move, that is, the seismic energy is consumed in the first direction X and the second direction Y at the same time.
In some embodiments, in the case of an earthquake, the vibration direction of the earthquake is the first direction X. The first stopper 221 may be caused to move in the first direction X by the seismic energy, so that the viscous liquid 240 in the first sub-cavity 111 and the viscous liquid 240 in the second sub-cavity 112 generate a damping force through the first through hole H1 to dissipate a part of the seismic energy. In addition, the first stopper 221 can also extrude the viscous liquid in the first cavity 110 into the second cavity 120, so as to drive the second stopper 231 to move along the second direction Y, so that the viscous liquid in the third sub-cavity 121 and the viscous liquid 240 in the fourth sub-cavity 122 generate a damping force through the second through hole H2, so as to consume the residual energy of the earthquake.
Similarly, in the case that the vibration direction of the earthquake is the second direction Y, the principle of consuming the earthquake in the embodiment that the vibration direction of the earthquake is the first direction X may be referred to, and details are not described here.
In some embodiments, in the case of an earthquake, the direction of vibration of the earthquake may be decomposed into a first component in a first direction X and a second component in a second direction Y. Wherein the first component may cause the first stopper 221 to move along the first direction X, so that the viscous liquid 240 in the first sub-cavity 111 and the viscous liquid 240 in the second sub-cavity 112 generate a damping force through the first through hole H1 to dissipate the first component of the earthquake; the second component may cause the second stopper 231 to move in the second direction Y, so that the viscous liquid in the third sub-chamber 121 and the viscous liquid 240 in the fourth sub-chamber 122 generate a damping force through the second through hole H2 to dissipate the second component of the earthquake.
It should be noted that the larger component of the first component and the second component can transfer the seismic energy to the smaller component direction for consumption through the viscous liquid 240, and the consumed energy shared by the first direction X and the second direction Y is approximately equal.
From the above, the pile foundation cap applied to the resistance to the bidirectional horizontal earthquake may be used to resist the earthquake in all directions.
