Detailed Implementation

[0062] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0063] As described in the background section, the support system for the poloidal field coil in a tokamak device should possess the following characteristics: 1. It should be able to withstand the weight of the poloidal field coil, ensuring that the coil is in a predetermined position before operation; 2. It should be able to resist strong electromagnetic forces, keeping the position of the poloidal field coil unchanged; 3. It should possess sufficient durability and stability to resist the thermal stress of the poloidal field coil and itself, and not experience excessive thermal deformation when subjected to the high temperatures generated during the startup and operation of the tokamak fusion device. Therefore, how to construct the support system for the poloidal field coil in a tokamak device has become a technical problem that urgently needs to be solved by those skilled in the art.

[0064] To solve the above problems, refer to Figure 1 , Figure 2, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8This invention provides a support system for a poloidal field coil in a tokamak device, comprising a circumferential field coil 110, two first poloidal field coils 120, two second poloidal field coils 130, two third poloidal field coils 140, two first support components 150, two second support components 160, and a third support component 170. One first poloidal field coil 120 is disposed at the top of the circumferential field coil 110, with its surface perpendicular to the surface of the circumferential field coil 110. The other first poloidal field coil 120 is disposed at the bottom of the circumferential field coil 110, with its surface perpendicular to the surface of the circumferential field coil 110. One second poloidal field coil 130 is coiled in the upper part of the circumferential field coil 110, with its surface perpendicular to the surface of the circumferential field coil 110. The other second poloidal field coil 130 is coiled in the lower part of the circumferential field coil 110, with its surface perpendicular to the surface of the circumferential field coil 110. Two third poloidal field coils 140 are respectively coiled around the middle of the circumferential field coil 110, with their respective planes perpendicular to the plane of the circumferential field coil 110. One first support assembly 150 is used to fix the top end of the circumferential 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 end of the circumferential field coil 110 and the other first poloidal field coil 120. One second support assembly 160 is used to fix the upper part of the circumferential field coil 110 and one of the second poloidal field coils 130, and the other second second support assembly 160 is used to fix the lower part of the circumferential field coil 110 and the other second poloidal field coil 130. A third support assembly 170 is used to fix the middle part of the circumferential field coil 110 and the two third poloidal field coils 140. The circumferential field coil 110 serves as a support base, cooperating with the first support assembly 150, the second support assembly 160, and the third support assembly 170. It effectively supports the two first poloidal field coils 120, the two second poloidal field coils 130, and the two third poloidal field coils 140, providing radial and vertical support forces to each. This ensures that each of these coils is in a predetermined position before operation. When subjected to strong electromagnetic forces, the positions of each coil remain essentially unchanged. Meanwhile, the first support component 150, the second support component 160 and the third support component 170 can limit the radial thermal deformation and vertical thermal deformation generated when the poloidal field coil is working as much as possible. Their own structures are very stable, thus playing a good limiting role for the poloidal field coil.

[0065] Specifically, in the example, such as 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 circumferential field coil 110, increasing the contact area when the first support assembly 150 is connected to the circumferential 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, which can better transfer the force, such as gravity, on the first support assembly 150 and the first polecular field coil 120 to the circumferential field coil 110, greatly improving the positional stability of the first polecular field coil 120. A first receiving groove is formed in the middle of the side of the first clamping plate 152 near the first polecular field coil 120. The second clamping plate 153 is arranged vertically opposite to the first clamping plate 152, and a first receiving groove is also formed in the middle of the side of the first polecular field coil 120. At least one first connecting rod 154 has its two ends fixed to one end of the first clamping plate 152 and one end of the second clamping plate 153, respectively, and at least one first connecting rod 154 has its two ends fixed to the other ends of the first clamping plate 152 and the second clamping plate 153, respectively. The first clamping plate 152, the second clamping plate 153, and the multiple first connecting rods 154 cooperate with each other to effectively clamp and fix the first poloidal field coil 120 when subjected to the alternating electromagnetic force and thermal stress of the fusion reaction, effectively limiting the radial thermal deformation and vertical thermal deformation of the first poloidal field coil 120 during operation. One end of one first side plate 155 is fixed to one end of the first base 151 by a second fastener 1591, and the other end is fixed to one end of the second clamping plate 153 by a third fastener 1592. One end of another first side plate 155 is fixed to the other end of the first base 151 by a second fastener 1591, and the other end is fixed to the other end of the second clamping plate 153 by a third fastener 1592. The two first side plates 155 further restrict the thermal deformation of the first pole-field coil 120 in the radial and vertical directions, improve the stability and durability of the first support assembly 150 structure, prevent the first pole-field coil 120 from overheating due to uneven local stress, and extend the service life of the first pole-field coil 120.

[0066] Preferably, there are ten first connecting rods 154. Five of the first connecting rods 154 are fixed at both ends to one end of the first clamping plate 152 and one end of the second clamping plate 153, respectively, and the other five first connecting rods 154 are fixed at both ends to the other end of the first clamping plate 152 and the other end of the second clamping plate 153, respectively.

[0067] Preferably, each first connecting rod 154 is a screw rod used in conjunction with a locking nut.

[0068] Preferably, such as Figure 3 and Figure 4As shown, each second fastener 1591 includes a bolt washer and a bolt shank. The bolt washer has a circular structure with a conical countersunk hole in the center. The top of the bolt shank has a nut that fits into the countersunk hole, and the bottom is screwed into a threaded hole on the first base 151. Thus, at high temperatures, the axial expansion of the second fastener 1591 is less than the vertical expansion of the first clamping plate 152, ensuring that the preload does not decrease and thus guaranteeing the stability of the connection at high temperatures. It should be noted that the bolt shank and bolt washer should be made of metals with different coefficients of thermal expansion. The structure of each first fastener is the same as that of each second fastener 1591, both possessing good thermal adaptability. Each third fastener 1592 includes a bolt washer, a bolt shank, and a nut. The bolt washer has a circular structure with a conical countersunk hole in the center. The top of the bolt shank has a nut that fits into the countersunk hole. The nut is screwed into the bottom of the bolt shank. Thus, at high temperatures, the axial expansion of the third fastener 1592 is less than the vertical expansion of the second clamping plate 153, thereby ensuring that the preload will not decrease and thus ensuring the stability of the connection at high temperatures.

[0069] Preferably, each first side plate 155 is in the shape of an "I" and has a first through hole 1551 in the middle. The first through hole 1551 can effectively resist thermal deformation, prevent the position of the first pole field coil 120 from shifting, prevent local stress concentration in the first support assembly 150 from causing damage to the structure of the first support assembly 150, and maintain stable confinement of the plasma.

[0070] Preferably, such as 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 limiting blocks 1571, two second traction ropes 1581, two second limiting 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 interlaced within one of the first side plates 155, with one end fixedly connected to one of the two fourth fasteners 1593, and the other end fixed to the end of the first side plate 155 near the first base 151. The other two first traction ropes 156 are interlaced within the other first side plate 155, with one end fixedly connected to the other two fourth fasteners 1593, and the other end fixed to the end of the first side plate 155 near the first base 151. Four fourth fasteners 1593 cooperate with four first traction ropes 156 to further limit the thermal deformation of the first pole-field coil 120 in the vertical direction. Two first limiting blocks 1571 are respectively disposed at opposite ends of the second clamping plate 153 to press against the corresponding ends of the second clamping plate 153 and the corresponding first side plates 155. Two second traction ropes 1581 are interlaced and pass through the interior of the second clamping plate 153. One end of each of the two second traction ropes 1581 is fixedly connected to the opposite ends of one of the first limiting blocks 1571, and the other end is fixedly connected to the opposite ends of the other first limiting block 1571. Two second limiting blocks 1572 are respectively disposed on the opposite sides of the two first side plates 155. Two third traction ropes 1582 are interlaced and pass through the interior of the first clamping plate 152. One end of each of the two third traction ropes 1582 is fixedly connected to the opposite ends of one of the second limiting blocks 1572, and the other end is fixedly connected to the opposite ends of the other second limiting block 1572. The two first limiting blocks 1571, the two second traction ropes 1581, the two second limiting blocks 1572, and the two third traction ropes 1582 cooperate to further limit the radial thermal deformation of the first pole-field coil 120.

[0071] Preferably, each fourth fastener 1593 includes a bolt washer and a bolt shank. The bolt washer has a circular structure with a conical recessed hole in the center. The top of the bolt shank has a nut that matches the recessed hole, and the bottom is connected to the first traction rope 156, providing good geothermal adaptability.

[0072] Preferably, each of the first traction rope 156, each of the second traction rope 1581 and each of the third traction rope 1582 is made of metal, which has good strength and rigidity.

[0073] Preferably, the two opposite ends of the second clamping plate 153 and the two first side plates 155 are respectively provided with first grooves for accommodating the first limiting block 1571. The mutually opposite sides of the two first side plates 155 are respectively provided with second grooves for accommodating the second limiting block 1572. In this way, the space utilization and structural stability are improved.

[0074] Specifically, in the example, such as 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, multiple second connecting rods 165, and two second side plates 166. Both first support plates 161 are triangular structures with parallel planes. Both first support plates 161 are fixed to the upper part of the circumferential field coil 110, or both first support plates 161 are fixed to the lower part of the circumferential field coil 110. The two first support plates 161 improve the stability of the connection between each second support assembly 160 and the circumferential 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, which can better transfer the forces, such as gravity, experienced by the second support assembly 160 and the second poloidal field coil 130 to the circumferential field coil 110, greatly improving the positional stability of the second poloidal field coil 130. A second receiving groove is formed in the middle of the side of the third clamping plate 163 near the second poloidal field coil 130. The fourth clamping plate 164 is arranged vertically opposite the third clamping plate 163, and a second receiving groove is also formed in the middle of the side of the fourth clamping plate 164 near the second poloidal field coil 130. At least one second connecting rod 165 is fixed at one end of the third clamping plate 163 and one end of the fourth clamping plate 164, respectively, and at least one second connecting rod 165 is fixed at the other end of the third clamping plate 163 and the other end of the fourth clamping plate 164, respectively. The third clamping plate 163, the fourth clamping plate 164 and the multiple second connecting rods 165 cooperate with each other to firmly clamp and fix the second poloidal field coil 130 when subjected to the alternating electromagnetic force and thermal stress of the fusion reaction, effectively limiting the radial thermal deformation and vertical thermal deformation of the second poloidal field coil 130 during operation. 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. The other second side plate 166 has one end fixed to the other end of the second base 162 by a second fastener 1591, and the other end 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 polecular field coil 130 in the radial and vertical directions, improving the stability and durability of the second support assembly 160 structure, preventing overheating due to uneven local stress on the second polecular field coil 130, and extending the service life of the second polecular field coil 130.

[0075] Preferably, there are ten second connecting rods 165. Five of the second connecting rods 165 are fixed at both ends to one end of the third clamping plate 163 and one end of the fourth clamping plate 164, respectively, and the other five are fixed at both ends to the other end of the third clamping plate 163 and the other end of the fourth clamping plate 164, respectively.

[0076] Preferably, each second connecting rod 165 is a screw rod used in conjunction with a locking nut.

[0077] Preferably, each second side plate 166 is in the shape of an "I" and has a second through hole 1661 in the middle. The second through hole 1661 can effectively resist thermal deformation, prevent the second pole from shifting to the position of the field coil 130, prevent local stress concentration in the second support assembly 160 from causing damage to the structure of the second support assembly 160, and maintain stable confinement of the plasma.

[0078] Preferably, each second support assembly 160 further includes four fourth fasteners 1593, four first traction ropes 156, two first limiting blocks 1571, two second traction ropes 1581, two second limiting blocks 1572, and two third traction ropes 1582. The four fourth fasteners 1593 are respectively installed at the four corners of the fourth clamping plate 164.

[0079] Specifically, in the example, such as Figure 1 and Figure 8As shown, the third support assembly 170 includes a third base 171, a second support plate 172, a fourth base 1731, a fifth clamping plate 1741, a sixth clamping plate 1751, multiple third connecting rods 1761, two third side plates 1771, a fifth base 1732, a seventh clamping plate 1742, an eighth clamping plate 1752, multiple fourth connecting rods 1762, and two fourth side plates 1772. The surface of the third base 171 is parallel to the tangent at the center of the circumferential field coil 110. One side of the third base 171 is fixed to the center of the circumferential 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 circumferential field coil 110, thereby improving the stability of the connection. The surface of the second support plate 172 is perpendicular to the surface of the third base 171. One side of the second support plate 172 is fixed to the other side of the third base 171. The forces, such as gravity, acting on the third support assembly 170 and the third pole-field coil 140 can be effectively transferred to the circumferential field coil 110, greatly improving the positional stability of the third pole-field coil 140. Multiple first clamping blocks are provided on the third base 171 to clamp the second support plate 172, limiting its back-and-forth swaying. The fourth base 1731 is fixed to the top of the second support plate 172 by first fasteners. Multiple second clamping blocks are provided on the fourth base 1731 to clamp the second support plate 172, limiting its back-and-forth swaying. The fifth clamping plate 1741 is fixed to the top of the fourth base 1731 by first fasteners. A third receiving groove is formed in the middle of the side of the fifth clamping plate 1741 near one of the third pole-field coils 140.

At least one third connecting rod 1761 has its two ends fixed to one end of the fifth clamping plate 1741 and one end of the sixth clamping plate 1751, respectively, and its two ends fixed to the other ends of the fifth clamping plate 1741 and the sixth clamping plate 1751, respectively. The fifth clamping plate 1741, the sixth clamping plate 1751, and the multiple third connecting rods 1761 cooperate with each other to effectively clamp and fix one of the third poloidal field coils 140 while bearing the alternating electromagnetic force and thermal stress of the fusion reaction, effectively limiting the radial and vertical thermal deformation of the third poloidal field coil 140 during operation. One end of one third side plate 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 restrict the thermal deformation of the third pole-field coil 140 in the radial and vertical directions, improving the stability and durability of the third support assembly 170 structure, preventing overheating due to uneven local stress on the third pole-field coil 140, and extending the service life of the third pole-field coil 140. The fifth base 1732 is fixed to the bottom end of the second support plate 172 by the first fastener. Multiple second clamping blocks are provided on the fifth base 1732 to clamp the second support plate 172, limiting the back-and-forth swing of the fifth base 1732.

The eighth clamping plate 1752 is arranged vertically opposite the seventh clamping plate 1742, and a fourth receiving groove is also formed in the middle of the side closest to the other third pole-field coil 140. At least one fourth connecting rod 1762 has its two ends fixed to one end of the seventh clamping plate 1742 and one end of the eighth clamping plate 1752, respectively. At least one fourth connecting rod 1762 has its two ends fixed to the other ends of the seventh clamping plate 1742 and the eighth clamping plate 1752, respectively. The seventh clamping plate 1742, the eighth clamping plate 1752, and the multiple fourth connecting rods 1762 cooperate with each other to effectively clamp and fix another third polecular field coil 140 while bearing the alternating electromagnetic force and thermal stress of the fusion reaction, effectively limiting the radial and vertical thermal deformation of the third polecular field coil 140 during operation. One end of one fourth side plate 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. The two fourth side plates 1772 further restrict the thermal deformation of the third pole-field coil 140 in the radial and vertical directions, improve the stability and durability of the third support assembly 170 structure, prevent the third pole-field coil 140 from overheating due to uneven local stress, and extend the service life of the third pole-field coil 140.

The four fourth fasteners 1593 cooperate with the four first traction ropes 156 to further limit the thermal deformation of one of the third pole-field coils 140 in the vertical direction. The other four fourth fasteners 1593 cooperate with the other four first traction ropes 156 to further limit the thermal deformation of the other third pole-field coil 140 in the vertical direction.
