Examples
In order to solve the technical problem that the polar field coil of the tokamak device in the prior art can generate overall radial displacement in the discharging process, the embodiment of the invention provides the polar field coil of the tokamak device and a flexible fixing device. In a first aspect, an embodiment of the present invention provides a flexible fixing device for a polar field coil of a tokamak apparatus, which is shown in fig. 1 to 4, and includes: a metal fixing block; the fixing groove is arranged on one side of the metal fixing block; the corrugated plate 3 is arranged in the fixing groove; and the bakelite plate 4 is arranged on the outer side of the corrugated plate and extrudes the corrugated plate into the fixing groove to form interference fit.
Referring to fig. 1, the flexible fixing device of the polar field coil of the tokamak device comprises a metal fixing block, a fixing groove is formed in the left side of the metal fixing block, a corrugated plate is arranged in the fixing groove, and an electric wood plate extrudes the corrugated plate to form interference fit in the fixing groove. Further, the fixing groove is a dovetail fixing groove 5.
The flexible fixture, when installed, may be mounted on the PF4 coil 7 of the tokamak device poloidal field coil. The specific working principle is as follows:
the upper end and the lower end of the polar field coil of the tokamak device are both provided with PF 1-4 coils, and when the flexible fixing device is installed, the flexible fixing device can be installed on PF4 coils 7 at the upper end and the lower end of the polar field coil of the tokamak device.
When the PF 1-4 coil generates radial displacement in one direction, the corrugated plates of the 180-degree flexible fixing device in the direction are extruded in different degrees to form a reverse force to act on the PF 1-4, the reverse force and the electromagnetic force are balanced in the discharging process, after the electromagnetic force disappears after the device is electrified, the force enables the PF 1-4 coil to move towards the direction of the reverse force resultant force of the 180-degree corrugated plates, and finally the PF 1-4 coil integrated body is extruded back to the initial position. The corrugated plate and the bakelite plate are fixed in the dovetail fixing groove in an interference fit mode, and the corrugated plate bears force when one side of the dovetail fixing groove is pressed; when the other side coil is far away from the structure, although the coil is separated from the corrugated plate, due to the prestress generated by interference fit between the corrugated plate and the dovetail fixing groove during installation, the bakelite plate and the corrugated plate cannot slide out of the dovetail fixing groove through annular motion.
Therefore, according to the embodiment of the invention, through the metal fixing block 1 of the flexible fixing device, the fixing groove, the corrugated plate and the bakelite plate, when the polar field coil of the tokamak device generates the acting force of radial displacement, the corrugated plate is extruded to balance the prestress forming interference fit in the fixing groove and the acting force generating radial displacement, so that the condition that the polar field coil of the tokamak device generates integral radial displacement in the discharging process is avoided.
Furthermore, the metal fixing block is connected with a supporting structure attachment strap 6.

After the PF 1-4 finishes the discharging process, because the electromagnetic force generated by electrifying the coil does not exist any more, the corrugated plate 3 generates the tendency of recovering deformation, the corrugated plate 3 generates a return thrust to the PF 1-4 coil, and when the corrugated plate 3 is gradually pushed back to the original position, the thrust of the corrugated plate 3 is also gradually reduced; when the thrust of the corrugated plate is equal to the friction force generated by the gravity of the PF 1-4 coil, the corrugated plate stops moving, and the coil is close to the initial position.
Furthermore, one side of bakelite plate is equipped with the arcwall face that is used for with the laminating of the outside of tokamak device polar field coil.
Referring to fig. 1-4, the flexible fixing device is mainly installed on the support structure access plate 6 of the polar field coil, and the metal fixing block 1 is connected with the support structure access plate 6 of the polar field coil through a countersunk screw; the metal fixing block 1 flexibly fixes the corrugated plate 3 and the arc-shaped bakelite plate 4 on the inner side of the dovetail fixing groove 5; and finally, the arc-shaped bakelite plate 4 is in surface contact with the PF4 coil, and the contact surface of the arc-shaped bakelite plate and the PF coil is matched through the arc-shaped surface, so that the tight matching of the connection surface is ensured.
Furthermore, the corrugated plate is made of cyanate ester materials.

This corrugated design is flexible to the displacement restriction of thrust piece, and the restriction power increases with the size of displacement is nonlinear geometric progression type, and when the integrated body of PF1 ~ 4 coil at the uniform velocity extrusion buckled plate, the resilience force of buckled plate will present geometric progression type and increase.
In a second aspect, an embodiment of the present invention provides a tokamak device poloidal field coil, and referring to fig. 4, a radial displacement balancing device for balancing radial displacement is arranged outside the tokamak device poloidal field coil; the radial displacement balancing device includes: and the flexible fixing devices are used for being attached to the outer side of the polar field coil of the Tokamak device.

Furthermore, all the flexible fixing devices are arranged on the same horizontal plane and are uniformly distributed on the outer side of the polar field coil of the Tokamak device.

Thus, the magnitude of the restraining force and the displacement increases geometrically.
Therefore, according to the embodiment of the invention, through the metal fixing block, the fixing groove, the corrugated plate and the bakelite plate of the flexible fixing device, when the polar field coil of the tokamak device generates the acting force of radial displacement, the corrugated plate is extruded into the fixing groove through the bakelite plate to form the prestress of interference fit and balance the acting force of radial displacement, so that the condition that the polar field coil of the tokamak device generates integral radial displacement in the discharging process is avoided.
