an anti-torsion, anti-seismic and tensile building structure for constructional engineering comprises a first wall body and a second wall body which are adjacently arranged, and further comprises a magnetic current damper for connecting the first wall body and the second wall body, wherein the magnetic current damper comprises a mounting cylinder 1, a power generation motor 2, a hydraulic rotating wheel 3, a piston 4, a rod piece 5, an excitation coil 6, a one-way pipeline 7, magnetorheological fluid and a controller,
one end of the mounting cylinder 1 is connected with the first wall, a first mounting cavity 1a, a second mounting cavity 1b and a sealing cavity 1c are sequentially arranged in the mounting cylinder 1 along the axial direction, and magnetorheological fluid is filled into the second mounting cavity 1b and the sealing cavity 1 c;
the power generation motor 2 is arranged in the first arrangement cavity 1a, the hydraulic runner 3 is coaxially and rotatably arranged in the second arrangement cavity 1b, an input shaft of the power generation motor 2 is coaxially and fixedly connected with the hydraulic runner 3, the second arrangement cavity 1b is also provided with an input pipe 1b1 and an output pipe 1b2 which are communicated with the outside, and when magnetorheological fluid flows into the second arrangement cavity 1b through the input pipe 1b1 and is discharged through the output pipe 1b2, the hydraulic runner 3 rotates in the second arrangement cavity 1 b;
the piston 4 is coaxially and slidably arranged in the sealed cavity 1c, the sealed cavity 1c is divided into a first deformation cavity and a second deformation cavity which are independent of each other by the piston 4, the first deformation cavity and the second deformation cavity are communicated with the input pipe 1b1 and the output pipe 1b2 through the one-way pipeline 7, and when the piston 4 slides in the sealed cavity 1c, the magnetorheological fluid sequentially flows through the input pipe 1b1, the second placement cavity 1b and the output pipe 1b 2;
the rod piece 5 is coaxially arranged at one end of the piston 4 and penetrates through the other end of the mounting cylinder 1, and the outer end of the rod piece 5 is connected with the second wall body;
the excitation coil 6 is sleeved on the mounting cylinder 1, and the excitation coil 6 is positioned outside the sealing cavity 1 c;
the generating motor 2 and the magnet exciting coil 6 are both electrically connected with the controller.
Based on the above embodiment, the hydraulic runner 3 is a runner in a water turbine, and the runner rotates coaxially when water flow enters the runner in the radial direction and is discharged from the end thereof;
when an earthquake occurs, the first wall body and the second wall body are relatively displaced, namely, the interval between the first wall body and the second wall body is changed, the magnetic current damper is connected with the first wall body and the second wall body, and the first wall body and the second wall body which are relatively displaced are driven to slide in the sealed cavity 1c through the rod piece 5 as the piston 4 is arranged in the sealed cavity 1c in a sliding manner and the rod piece 5 which is coaxially connected with the piston 4 is connected with the second wall body;
the volume of the first deformation cavity and the volume of the second deformation cavity are changed, and the first deformation cavity and the second deformation cavity are communicated with the input pipe 1b1 and the output pipe 1b2 through the one-way pipeline 7, so that when the piston 4 axially reciprocates in the sealed cavity 1c, magnetorheological fluid can always sequentially pass through the input pipe 1b1, the second placing cavity 1b and the output pipe 1b2 through the one-way pipeline 7, the hydraulic runner 3 can rotate in the second placing cavity 1b, the power generation motor 2 is arranged in the first placing cavity 1a, the input shaft of the power generation motor is coaxially and fixedly connected with the hydraulic runner 3, and the rotating hydraulic runner 3 can input torque to the power generation motor 2;
because the power generation motor 2 and the excitation coil 6 are electrically connected with the controller, the current generated by the power generation motor 2 can pass through the excitation coil 6, then the excitation coil 6 generates magnetic lines, the excitation coil 6 is sleeved on the mounting barrel 1, and the excitation coil 6 is positioned outside the sealing cavity 1c, so that the magnetorheological fluid presents a Bingham fluid state with high viscosity and low fluidity when a magnetic field is applied to the excitation coil 6, then the piston 4 moves relative to the sealing cavity 1c to shear the magnetorheological fluid, and further damping force is generated, and therefore the relative vibration force between the first wall body and the second wall body is reduced;
and when the piston 4 does not displace relative to the sealing cavity 1c, namely the magnetorheological fluid does not flow, the hydraulic runner 3 cannot rotate, the power generation motor 2 does not generate current and passes through the excitation coil 6, and further the excitation coil 6 does not generate magnetic field action on the magnetorheological fluid, the magnetorheological fluid has the property of low-viscosity Newtonian fluid, so that when no earthquake occurs, the first wall body and the second wall body are relatively stable.
Further, in order to solve the problem that the one-way pipe 7 can always guide the magnetorheological fluid to pass through the input pipe 1b1, the second containing chamber 1b and the output pipe 1b2 when the piston 4 slides in the sealed chamber 1c, as shown in fig. 5, 6 and 12:

Based on the above embodiment, when the distance between the first wall and the second wall is reduced due to an earthquake, that is, the piston 4 slides in the sealed cavity towards the hydraulic runner 3, so that the volume of the first deformation cavity is reduced, the volume of the second deformation cavity is increased, and the first deformation cavity is communicated with the input pipe 1b1 through the first pipeline 7a, so that the magnetorheological fluid in the first deformation cavity flows into the second installation cavity through the input pipe 1b1 and then is discharged outside through the output pipe 1b2, in the process, the magnetorheological fluid in the first deformation cavity is discharged into the second deformation cavity through the third pipeline 7e without being increased in pressure due to the conduction of the third check valve 7f from the second deformation cavity to the input pipe 1b 1; the second deformation cavity is communicated with the output pipe 1b2 through a second pipeline 7c, so that magnetorheological fluid extruded out of the first deformation cavity flows into the second deformation cavity, and the magnetorheological fluid drives the hydraulic runner 3 to rotate in the second arrangement cavity 1b in the flowing process, and further generates torque on an input shaft of the power generation motor 2; in the process, the fourth one-way valve 7h is communicated with the first deformation cavity from the output pipe 1b2, so that the magnetorheological fluid passing through the output pipe 1b2 cannot be discharged into the first deformation cavity again;
when the distance between the first wall and the second wall is increased due to an earthquake, namely the piston 4 slides in the direction away from the hydraulic runner 3 in the sealed cavity, so that the volume of the second deformation cavity is reduced, the volume of the first deformation cavity is increased, and the second deformation cavity is communicated with the input pipe 1b1 through the third pipeline 7e, so that the magnetorheological fluid in the second deformation cavity flows into the second setting cavity 1b through the input pipe 1b1 through the third pipeline 7e, in the process, the magnetorheological fluid is driven to rotate in the second setting cavity 1b by the magnetorheological fluid in the flowing process due to the conduction of the first one-way valve 7b from the first deformation cavity to the input pipe 1b1, so that the magnetorheological fluid extruded from the second deformation cavity cannot be directly discharged into the second setting cavity 1b, and the first deformation cavity is unidirectionally communicated with the fourth one-way valve 7g, so that the magnetorheological fluid drives the hydraulic runner 3 to rotate in the second setting cavity 1b, and further generates torque on the input shaft of the power generation motor 2, in the process, the second check valve 7d is communicated with the second deformation chamber from the output pipe 1b2, so that the magnetorheological fluid discharged from the output pipe 1b2 cannot flow into the second deformation chamber through the second pipeline 7 c.
Further, the installation cylinder 1 and the one-way pipeline 7 provided by the present application still have the defect of being unable to resist torque when being connected with the first wall and the second wall, and in order to solve the problem, as shown in fig. 3:

Further, the direct coaxial connection between the input shaft of the generator motor 2 and the hydraulic runner 3 still has the defect that the output torque of the hydraulic runner 3 is small, which may cause the current generated by the generator motor 2 to be small, and in order to solve this problem, as shown in fig. 4 and 13:

Further, the hydraulic runner 3 provided by the present application drives the input shaft of the power generation motor 2 to rotate, and still has a defect that vibration is easily transmitted to the hydraulic runner 3 during an earthquake and power generation cannot be stably performed, in order to solve the problem, as shown in fig. 4 and 13:
the magnetic current damper also comprises a flywheel 9b, and the flywheel 9b is coaxially arranged on the input shaft of the generating motor 2.
Based on the above embodiment, the flywheel 9b is disposed on the input shaft of the generator motor 2, so that the energy of the structural vibration can be consumed, and further, the flywheel can be used as a damper for energy consumption and shock absorption, and the vibration transmitted to the generator motor 2 can be reduced, thereby ensuring that the generator motor 2 can work normally and stably.
Further, the hydraulic runner 3 provided by the present application drives the input shaft of the generator motor 2 to rotate, and still has a defect that when the hydraulic runner 3 stops rotating, a differential is easily generated to affect the output overload of the generator motor 2, in order to solve this problem, as shown in fig. 4 and 13:

Further, the piston 4 provided by the present application still has a defect that the magnetorheological fluid is easy to flow in the first deformation chamber and the second deformation chamber through the gap between the seal chamber and the circumferential surface of the piston 4 when sliding in the seal chamber, and in order to solve the problem, as shown in fig. 7:

As shown in fig. 14 and 15:
an anti-torsion, anti-seismic and tensile building structure for constructional engineering comprises a first wall body and a second wall body which are adjacently arranged, and further comprises a current damper for connecting the first wall body and the second wall body, wherein the current damper comprises a placing cylinder 1, a power generation motor 2, a hydraulic rotating wheel 3, a piston 4, a rod piece 5, a one-way pipeline 7, electrorheological fluid and a controller,

the power generation motor 2 is arranged in the first arrangement cavity 1a, the hydraulic runner 3 is coaxially and rotatably arranged in the second arrangement cavity 1b, an input shaft of the power generation motor 2 is coaxially and fixedly connected with the hydraulic runner 3, the second arrangement cavity 1b is also provided with an input pipe 1b1 and an output pipe 1b2 which are communicated with the outside, and when the electrorheological fluid flows into the second arrangement cavity 1b through the input pipe 1b1 and is discharged through the output pipe 1b2, the hydraulic runner 3 rotates in the second arrangement cavity 1 b;
the piston 4 is coaxially and slidably arranged in the sealed cavity 1c, the sealed cavity 1c is divided into a first deformation cavity and a second deformation cavity which are independent of each other by the piston 4, the first deformation cavity and the second deformation cavity are communicated with the input pipe 1b1 and the output pipe 1b2 through a one-way pipeline 7, and when the piston 4 slides in the sealed cavity 1c, the electrorheological fluid sequentially flows through the input pipe 1b1, the second placement cavity 1b and the output pipe 1b 2;
the rod piece 5 is coaxially arranged at one end of the piston 4 and penetrates through the other end of the mounting cylinder 1, and the outer end of the rod piece 5 is connected with the second wall body;
the generating motor 2 and the sealed cavity are both electrically connected with the controller.
Based on the embodiment, when an earthquake occurs, the first wall body and the second wall body generate relative displacement, namely, the interval between the first wall body and the second wall body is changed, the current damper is connected with the first wall body and the second wall body, and the first wall body and the second wall body which generate relative displacement drive the piston 4 to slide in the sealed cavity 1c through the rod piece 5 because the piston 4 is arranged in the sealed cavity 1c in a sliding manner and the rod piece 5 which is coaxially connected with the piston 4 is connected with the second wall body;
the volumes of the first deformation cavity and the second deformation cavity are changed, and the first deformation cavity and the second deformation cavity are communicated with the input pipe 1b1 and the output pipe 1b2 through the one-way pipeline 7, so that when the piston 4 axially reciprocates in the sealed cavity 1c, the electrorheological fluid can always sequentially pass through the input pipe 1b1, the second placing cavity 1b and the output pipe 1b2 through the one-way pipeline 7, the hydraulic runner 3 can rotate in the second placing cavity 1b, the power generation motor 2 is arranged in the first placing cavity 1a, and the input shaft of the power generation motor is coaxially and fixedly connected with the hydraulic runner 3, so that the rotating hydraulic runner 3 can input torque to the power generation motor 2;
because the power generation motor 2 and the sealed cavity are electrically connected with the controller, the current generated by the power generation motor 2 can pass through the sealed cavity with the conductive property, so that the viscosity of the electrorheological fluid is increased when an external electric field is applied, and then the piston 4 moves relative to the sealed cavity 1c to shear the electrorheological fluid, so as to generate damping force, thereby reducing the relative vibration force between the first wall body and the second wall body;
and when the piston 4 does not displace relative to the sealed cavity 1c, namely the electrorheological fluid does not flow, the hydraulic runner 3 cannot rotate, and the power generation motor 2 does not generate current and passes through the sealed cavity any more, so that the electrorheological fluid has low viscosity when the sealed cavity does not generate electric field action on the electrorheological fluid, and the first wall and the second wall are relatively stable when no earthquake occurs.
