性の点で充分な健全性の確保ができない。However, in recent years, a fusion device employing a superconducting toroidal magnetic field coil formed of a superconductor as a toroidal magnetic field coil has been proposed because of the necessity of a strong magnetic field and a high magnetic field.

The structure cannot be freely designed as in the case of using a normal conducting toroidal magnetic field coil, so that sufficient soundness cannot be ensured in terms of earthquake resistance.

く有効な剛性を有する支持機構を備えることである。As mentioned above, the problem of seismic resistance of a fusion device equipped with a superconducting toroidal magnetic field coil is that the vertical support mechanism that supports the structure that composes the fusion device reduces the horizontal thermal deformation of the structure. This is because the rigidity in the horizontal direction is insufficient in order not to be restrained. Therefore, in order to solve this problem, a support mechanism for directly supporting a horizontal force in the horizontal direction is provided with a support mechanism having effective rigidity without restraining thermal deformation.

形に対し、これを拘束することはない。In FIG. 3, an attachment point A is a connection point between the vacuum vessel 2 or the shear panel unit 5 and one end of the vibration-proof supporting device 14 or 15, and a mounting point B is a heat-insulating vacuum vessel 10 and the vibration-proof supporting device 14 or
It is the point of connection with one end of 15 Usually, in a torus-type fusion device, the immobile reference point for the temperature change is at the center of the torus. Therefore, the displacement of the attachment point A at the time of a temperature change moves in the radial direction on a line connecting the center of the torus and the attachment point A. In addition, on the circumference of the same radius, the displacement is the same at any position in the circumferential direction as long as the temperature distribution in the circumferential direction is uniform. The anti-vibration support devices 14 and 15
Since the mounting point A is a movable end and the mounting portion B is a fixed end, the pin is connected rotatably in a pin-locking manner, so that the locus of the moving mounting point A is centered on the fixed mounting point B.
It would be present on an arc of circumference 14, 15 of flow l s as radius. If the length l s of the anti-vibration support devices 14 and 15 is sufficiently long with respect to the displacement δ of the moving mounting point A,
Since each of the rotation angles 15 is extremely small, the trajectory of the moving attachment point A may be practically treated as a straight line. Therefore, if the fixed mounting point B of the vibration isolator 14 and 15 is provided on a line perpendicular to the line connecting the center of the torus and the moving mounting point A, the locus of the moving mounting point A is practically the center of the torus. Even if it exists on the line connecting the moving attachment point A, it may be acceptable. As described above, the anti-vibration support devices 14 and 15 in this embodiment are
Does not restrict the thermal deformation of the vacuum vessel 2 or the superconducting toroidal magnetic field coil 4.

The anti-vibration support devices 14 and 15 in the present embodiment are provided in plural sets on the circumference of the torus. On the other hand, the vacuum vessel 2 and the shear panel section 5 form an annular body firmly connected in the torus direction, and the rigidity of the annular body itself is sufficiently rigid. If the rigidity of these annular bodies is sufficiently rigid, the anti-vibration support device for suppressing the horizontal vibration of the annular bodies will work regardless of the position of the annular body in the direction to be suppressed. That is, the anti-vibration support devices 14, 15 arranged in the section line direction
Has an effect of suppressing vibration in a direction parallel to the direction.
If three or more sets of anti-vibration support devices 14 and 15 are arranged on the circumference of the pipe under the same pipe, a uniform suppression function in any horizontal direction can be obtained by combining the suppression forces. Have. In this case, the rigidity of the anti-vibration support devices 14 and 15 is simple tensile and compressive rigidity in the axial direction of the connecting rod, and can be easily selected by appropriately selecting the cross-sectional area with respect to the length. It can have sufficient rigidity. In this way, the configuration of the rod vibration supporting devices 14 and 15 of the present embodiment allows the thermal deformation to escape without being restrained, and also provides a support rigidity effective for improving the earthquake resistance. It is.

成し、大きな剛性を有するものである。In this embodiment, one end of each of the vibration-isolation supporting devices 14 and 15 is connected to the heat-insulating vacuum vessel 10. However, since the heat-insulating vacuum vessel 10 is a very large thin-walled cylinder, a strong load is applied to the cylindrical portion. In the case of acting, local deformation is likely to occur in the cylindrical portion. This local deformation eventually governs the rigidity of the entire vibration isolating support device, and makes it difficult to secure the necessary support rigidity. Therefore, when implementing the above-described configuration, the insulated vacuum container 10
Effective reinforcement is required to prevent local deformation. First
The reinforcing wheels 16 and 17 shown in FIGS. 2 and 3 have this function, and the fixed support points B are respectively provided on the reinforcing wheels 16 and 1.
7 is provided so as to disperse a horizontal load acting locally on the entire heat-insulated vacuum vessel 10 to prevent local deformation and secure effective rigidity. Further, in this embodiment, the reinforcing wheel 16 at the lower position is brought into contact with or buried in the floor surface of the foundation 13 to integrate the floor with the floor, thereby achieving a more effective reinforcing effect and improving rigidity. . In addition, for the load transmitted to the reinforcing wheel 17 at the upper position, a reinforcing column 18 that connects the upper and lower reinforcing wheels 16, 17 is provided,
The opening 11 of the heat insulating vacuum vessel 10 was reinforced. This portion forms a hollow box-shaped cross section together with the wall surface of the cylindrical portion of the heat-insulated vacuum vessel 10, and has high rigidity.

由度が得られる効果があり、極めて実用性が高い。Further, the installation position in the height direction of the anti-vibration support device 14 that supports the vacuum vessel 2 is determined by the fact that the rigidity of the vacuum vessel 2 is sufficiently rigid both in the circumferential direction and in the height direction. But there is no problem practically. On the other hand, the optimum installation position of the anti-vibration support device 15 that supports the superconducting toroidal magnetic field coil 4 is determined by the coil mass distribution. When the shear panel portion 5 is included, the distribution of the main mass is equal to the upper and lower shear panel portions 5.
And the superconducting toroidal magnetic field coil body portion connecting them forms a columnar shape having relatively low rigidity, so that the superconducting toroidal magnetic field coil portion is dispersed in two upper and lower portions to directly support the shear panel portion 5. It is better to do. In consideration of this, it is noted that the rigidity of the insulated vacuum vessel 10 is higher on the lower reinforcing wheel 16 side than on the upper reinforcing wheel 17 side, and the vibration isolating support device 14 of the vacuum vessel 2 is installed on the lower side. However, it is appropriate that the anti-vibration support device 15 for the superconducting toroidal magnetic field coil 4 is provided at two upper and lower positions. Further, in the present embodiment, a slight contrivance is made on the specific configuration of the vibration isolation support devices 14 and 15. In the above description, it is assumed that the anti-vibration support devices 14 and 15 do not have their own temperature change and their length l s does not change. In the vibration isolating support device 14 of the vacuum vessel 2, the temperature rise of the vacuum vessel 2 is not so high, the joint thereof can be sufficiently cooled, and there is practically no change in temperature. . However, in the anti-vibration support device 15 for the superconducting toroidal magnetic field coil 4, it is necessary to eliminate as much as possible the heat that enters the superconducting coil system side at an extremely low temperature in the normal temperature range. The length of the anti-vibration support device 15 is
Since l s undergoes a large change, it is necessary to take a configuration to compensate for this. FIG. 4 shows an example of this configuration, and FIG. 5 explains its operation. As shown in the figure, two sets of anti-vibration support devices 15A and 15B, which are arranged in a clockwise direction and a counterclockwise direction in a cutting line direction, are combined with a vibration-proof support device 15 for supporting the superconducting toroidal magnetic field coil 4. One end of each is connected to a common pin C at a common mounting point C, and the connecting pin is slidably engaged with an engaging groove 19 provided in the heat-insulating vacuum vessel 10.
Are provided in parallel on a line passing through the center of the torus. The operation of this configuration will be described with reference to FIG. The attachment points A 1 and A 2 on the side of the superconducting toroidal magnetic field coil 4 move on a line connecting the points and the center O of the torus when the temperature changes, and the attachment points A 1 and A 2 are A 1 ′ , A 2 ′. If the lengths of the anti-vibration support devices 15A and 15B are configured to be the same, A 1 ,
The points A 2 and C form an isosceles triangle having the point C as a vertex. Since the points A 1 and A 2 are located on the same radius and undergo the same temperature change, their movement amounts are the same. Accordance connexion, vibration-damping support device 15A, if 15B is subjected to the same temperature change, regardless of the temperature, since its length is identical, the position C after movement of point C 'and A 1', The triangle formed by A 2 ′ forms an isosceles triangle having the point C ′ as the vertex, and the movement of C ′ moves on a line connecting the point C and the torus center O point.
As described above, according to this configuration, even if the anti-vibration support device 15 receives a temperature change, it compensates for its deformation, and does not restrict the thermal deformation of the superconducting toroidal magnetic field coil 4; A support device is obtained. Further, in this configuration, since it is not necessary to dispose the anti-vibration support devices 15A and 15B accurately in the direction of the cutting line, there is an effect that a great degree of freedom can be obtained for the design of the installation, which is extremely practical. .

Although the case where 19 is provided has been described, functionally, this is reversed, and the movable mounting point side is set to one position, and the supporting device engaging groove 19 is provided.
The same applies to the case where a pin is connected at two mounting points forming a pair on the fixed mounting side.
