DETAILED DESCRIPTION

[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] As described in the background technology, the support system of the poloidal field coil in the tokamak device should have the following characteristics: 1. It should be able to bear the weight of the poloidal field coil to ensure that the poloidal field coil is in the predetermined position before operation; 2. It should be able to resist strong electromagnetic force to keep the position of the poloidal field coil unchanged; 3. It should have sufficient durability and stability to resist the thermal stress of the poloidal field coil and itself, and not produce excessive thermal deformation when subjected to the high temperature generated by the startup and operation of the tokamak fusion device. Therefore, how to construct the support system of the poloidal field coil in the tokamak device has become a technical problem that needs to be solved urgently by those skilled in the art.

[0020] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The present invention provides a support system for a poloidal field coil in a tokamak device, comprising a toroidal field coil 110, two first poloidal field coils 120, two second poloidal field coils 130, two third poloidal field coils 140, two first support assemblies 150, two second support assemblies 160 and a third support assembly 170. One of the first poloidal field coils 120 is arranged at the top of the toroidal field coil 110, and the surface on which it is located is perpendicular to the surface on which the toroidal field coil 110 is located. Another first poloidal field coil 120 is arranged at the bottom of the toroidal field coil 110, and the surface on which it is located is perpendicular to the surface on which the toroidal field coil 110 is located. One of the second poloidal field coils 130 is arranged at the upper part of the toroidal field coil 110, and the surface on which it is located is perpendicular to the surface on which the toroidal field coil 110 is located. Another second poloidal field coil 130 is arranged at the lower part of the toroidal field coil 110, and the surface on which it is located is perpendicular to the surface on which the toroidal field coil 110 is located. The two third poloidal field coils 140 are respectively arranged in the middle of the toroidal field coil 110, and the surfaces where they are located are perpendicular to the surfaces where the toroidal field coil 110 is located. One of the first support assemblies 150 is used to fix the top of the toroidal field coil 110 and one of the first poloidal field coils 120, and the other first support assembly 150 is used to fix the bottom of the toroidal field coil 110 and the other first poloidal field coil 120. One of the second support assemblies 160 is used to fix the upper part of the toroidal field coil 110 and one of the second poloidal field coils 130, and the other second support assembly 160 is used to fix the lower part of the toroidal field coil 110 and the other second poloidal field coil 130. The third support assembly 170 is used to fix the middle part of the toroidal field coil 110 and the two third poloidal field coils 140. The toroidal field coil 110, as a supporting base, cooperates with the first supporting assembly 150, the second supporting assembly 160, and the third supporting assembly 170, and can effectively carry two first poloidal field coils 120, two second poloidal field coils 130, and two third poloidal field coils 140, and provide radial support force and vertical support force for each first poloidal field coil 120, each second poloidal field coil 130, and each third poloidal field coil 140, to ensure that each first poloidal field coil 120, each second poloidal field coil 130, and each third poloidal field coil 140 are in a predetermined position before operation. When subjected to strong electromagnetic force, the position of each first poloidal field coil 120, each second poloidal field coil 130, and each third poloidal field coil 140 remains substantially unchanged. At the same time, the first support assembly 150, the second support assembly 160 and the third support assembly 170 can limit the radial thermal deformation and the vertical thermal deformation generated when the poloidal field coil is working as much as possible, and their own structure is very stable, thereby playing a good limiting role for the poloidal field coil.

[0021] Specifically, in the example, Figure 1 , Figure 2 and Figure 3 As shown, each first support assembly 150 includes a first base 151, a first clamping plate 152, a second clamping plate 153, a plurality of first connecting rods 154 and two first side plates 155. The first base 151 is formed at the top or bottom of the toroidal field coil 110, which increases the contact area when the first support assembly 150 is connected to the toroidal field coil 110, thereby improving the stability of the connection. The first clamping plate 152 is fixed to the first base 151 by a first fastener, and the force, such as gravity, exerted on the first support assembly 150 and the first poloidal field coil 120 can be better transferred to the toroidal field coil 110, greatly improving the stability of the position of the first poloidal field coil 120. The first clamping plate 152 is formed with a first accommodating groove in the middle of one side surface close to the first poloidal field coil 120. The second clamping plate 153 is arranged opposite to the first clamping plate 152 in the upper and lower directions, and is also formed with a first accommodating groove in the middle of one side surface close to the first poloidal field coil 120. The two ends of at least one first connecting rod 154 are respectively fixed to one end of the first clamping plate 152 and one end of the second clamping plate 153, and the two ends of at least one first connecting rod 154 are respectively fixed to the other end of the first clamping plate 152 and the other end of the second clamping plate 153. The first clamping plate 152, the second clamping plate 153 and the plurality of first connecting rods 154 cooperate with each other, and when subjected to the alternating electromagnetic force and thermal stress of the fusion reaction, the first poloidal field coil 120 is still well clamped and fixed, and the first poloidal field coil 120 is effectively limited to be thermally deformed in the radial direction and in the vertical direction when working. One end of one of the first side plates 155 is fixed to one end of the first base 151 by the second fastener 1591, and the other end is fixed to one end of the second clamping plate 153 by the third fastener 1592. One end of another first side plate 155 is fixed to the other end of the first base 151 by the second fastener 1591, and the other end is fixed to the other end of the second clamping plate 153 by the third fastener 1592. The two first side plates 155 further limit the thermal deformation of the first poloidal field coil 120 in the radial and vertical directions, improve the stability and durability of the structure of the first support assembly 150, prevent the first poloidal field coil 120 from overheating due to local uneven force, and extend the service life of the first poloidal field coil 120.

[0022] Preferably, there are ten first connecting rods 154. Two ends of five first connecting rods 154 are respectively fixed to one end of the first clamping plate 152 and one end of the second clamping plate 153, and two ends of the other five first connecting rods 154 are respectively fixed to the other end of the first clamping plate 152 and the other end of the second clamping plate 153.

[0023] Preferably, each first connecting rod 154 is a screw rod used in conjunction with a locking nut.

[0024] Preferably, if Figure 3 and Figure 4As shown, each second fastener 1591 includes a bolt pad and a bolt rod. The bolt pad is a circular structure with a conical sink hole formed in the middle. A nut matching the sink hole is formed at the top of the bolt rod, and the bottom is screwed to the threaded hole on the first base 151. In this way, at high temperatures, the axial expansion amplitude of the second fastener 1591 is smaller than the expansion amplitude of the first clamping plate 152 in the vertical direction, thereby ensuring that the preload force will not be reduced, thereby ensuring the stability of the connection at high temperatures. It should be noted that the bolt rod and the bolt pad should be made of metal materials with different thermal expansion coefficients. The structure of each first fastener is the same as that of each second fastener 1591, and both have good thermal adaptability. Each third fastener 1592 includes a bolt pad, a bolt rod and a nut. The bolt pad is a circular structure with a conical sink hole formed in the middle. A nut matching the sink hole is formed at the top of the bolt rod. The nut is screwed to the bottom end of the bolt rod. In this way, at high temperatures, the axial expansion amplitude of the third fastener 1592 is smaller than the vertical expansion amplitude of the second clamping plate 153, thereby ensuring that the preload force will not be reduced, thereby ensuring the stability of the connection at high temperatures.

[0025] Preferably, each first side plate 155 is in an "I" shape, and a first through hole 1551 is provided in the middle. The first through hole 1551 can effectively resist thermal deformation, prevent the position of the first poloidal field coil 120 from shifting, prevent the local stress concentration of the first support assembly 150 from damaging the structure of the first support assembly 150, and maintain stable confinement of the plasma.

[0026] Preferably, if Figure 3 , Figure 4 , Figure 5 and Figure 6Each first support assembly 150 further includes four fourth fasteners 1593, four first traction ropes 156, two first limit blocks 1571, two second traction ropes 1581, two second limit blocks 1572 and two third traction ropes 1582. The four fourth fasteners 1593 are respectively installed at the four corners of the second clamping plate 153. Two of the first traction ropes 156 are cross-through in one of the first side panels 155, one end of which is fixedly connected to two of the fourth fasteners 1593 in a one-to-one correspondence, and the other end is respectively fixed to one end of the first side panel 155 close to the first base 151. Another two first traction ropes 156 are cross-through in another first side panel 155, one end of which is fixedly connected to another two of the fourth fasteners 1593 in a one-to-one correspondence, and the other end is respectively fixed to one end of the first side panel 155 close to the first base 151. The four fourth fasteners 1593 cooperate with the four first traction ropes 156 to further limit the thermal deformation of the first poloidal field coil 120 in the vertical direction. The two first limit blocks 1571 are respectively arranged at the opposite ends of the second clamping plate 153 to press the corresponding ends of the second clamping plate 153 and the first side plates 155 at the corresponding ends. The two second traction ropes 1581 are cross-arranged inside the second clamping plate 153. One end of the two second traction ropes 1581 is respectively fixedly connected to the opposite ends of one of the first limit blocks 1571, and the other end is respectively fixedly connected to the opposite ends of the other first limit block 1571. The two second limit blocks 1572 are respectively arranged on the mutually opposite sides of the two first side plates 155. The two third traction ropes 1582 are cross-arranged inside the first clamping plate 152. One end of the two third traction ropes 1582 is fixedly connected to the opposite ends of one of the second limit blocks 1572, and the other end is fixedly connected to the opposite ends of the other second limit block 1572. The cooperation of the two first limit blocks 1571, the two second traction ropes 1581, the two second limit blocks 1572 and the two third traction ropes 1582 can further limit the thermal deformation of the first poloidal field coil 120 in the radial direction.

[0027] Preferably, each fourth fastener 1593 includes a bolt pad and a bolt rod. The bolt pad is a circular structure with a conical sink hole formed in the middle. A nut matching the sink hole is formed at the top of the bolt rod, and the bottom end is connected to the first traction rope 156, which has good thermal adaptability.

[0028] Preferably, each first traction rope 156 , each second traction rope 1581 and each third traction rope 1582 is made of metal, which has good strength and rigidity.

[0029] Preferably, first grooves for accommodating the first limit blocks 1571 are respectively provided on the two opposite ends of the second clamping plate 153 and the two first side plates 155. Second grooves for accommodating the second limit blocks 1572 are respectively provided on the mutually opposite sides of the two first side plates 155. In this way, the space utilization and structural stability are improved.

[0030] Specifically, in the example, Figure 1 and Figure 7 As shown, each second support assembly 160 includes two first support plates 161, a second base 162, a third clamping plate 163, a fourth clamping plate 164, a plurality of second connecting rods 165 and two second side plates 166. The two first support plates 161 are both triangular structures, and the planes where they are located are parallel to each other. The two first support plates 161 are both fixed to the upper part of the toroidal field coil 110, or the two first support plates 161 are both fixed to the lower part of the toroidal field coil 110. The two first support plates 161 improve the stability of the connection between each second support assembly 160 and the toroidal field coil 110. The second base 162 is fixed to the two first support plates 161. The third clamping plate 163 is fixed to the second base 162 by a first fastener, and the force, such as gravity, exerted on the second support assembly 160 and the second poloidal field coil 130 can be better transferred to the toroidal field coil 110, which greatly improves the stability of the position of the second poloidal field coil 130. The third clamping plate 163 is formed with a second accommodating groove in the middle of one side surface close to the second poloidal field coil 130. The fourth clamping plate 164 is arranged vertically opposite to the third clamping plate 163, and is also formed with a second accommodating groove in the middle of one side surface close to the second poloidal field coil 130. The two ends of at least one second connecting rod 165 are respectively fixed to one end of the third clamping plate 163 and one end of the fourth clamping plate 164, and the two ends of at least one second connecting rod 165 are respectively fixed to the other end of the third clamping plate 163 and the other end of the fourth clamping plate 164. The third clamping plate 163, the fourth clamping plate 164 and the plurality of second connecting rods 165 cooperate with each other, and when subjected to the alternating electromagnetic force and thermal stress of the fusion reaction, the second poloidal field coil 130 is still well clamped and fixed, and the second poloidal field coil 130 is effectively limited to be thermally deformed in the radial direction and in the vertical direction when the second poloidal field coil 130 is working. One end of one of the second side plates 166 is fixed to one end of the second base 162 by a second fastener 1591, and the other end is fixed to one end of the fourth clamping plate 164 by a third fastener 1592. One end of the other second side plate 166 is fixed to the other end of the second base 162 by a second fastener 1591, and the other end is fixed to the other end of the fourth clamping plate 164 by a third fastener 1592. The two second side plates 166 further limit the thermal deformation of the second poloidal field coil 130 in the radial and vertical directions, improve the stability and durability of the structure of the second support assembly 160, prevent the second poloidal field coil 130 from being overheated due to uneven local force, and extend the service life of the second poloidal field coil 130.

One side of the third base 171 is fixed to the middle part of the toroidal field coil 110 by a first fastener. The third base 171 increases the contact area when the third support assembly 170 is connected to the toroidal field coil 110, thereby improving the stability of the connection. The surface where the second support plate 172 is located is perpendicular to the surface where the third base 171 is located. One side of the second support plate 172 is fixed to the other side of the third base 171.

The fifth clamping plate 1741, the sixth clamping plate 1751 and the plurality of third connecting rods 1761 cooperate with each other, and when subjected to the alternating electromagnetic force and thermal stress of the fusion reaction, they still well clamp and fix one of the third poloidal field coils 140, effectively limiting the thermal deformation of the third poloidal field coil 140 in the radial direction and in the vertical direction during operation. One end of one of the third side plates 1771 is fixed to one end of the fourth base 1731, and the other end is fixed to one end of the sixth clamping plate 1751. One end of another third side plate 1771 is fixed to the other end of the fourth base 1731, and the other end is fixed to the other end of the sixth clamping plate 1751.The two third side plates 1771 further limit the thermal deformation of the third poloidal field coil 140 in the radial and vertical directions, improve the stability and durability of the structure of the third support assembly 170, prevent the third poloidal field coil 140 from being overheated due to uneven local force, and extend the service life of the third poloidal field coil 140.

One end of one of the fourth side plates 1772 is fixed to one end of the fifth base 1732, and the other end is fixed to one end of the eighth clamping plate 1752. One end of another fourth side plate 1772 is fixed to the other end of the fifth base 1732, and the other end is fixed to the other end of the eighth clamping plate 1752.
