Description

Technical Field

[0001] This utility model relates to the field of nuclear fusion equipment technology, specifically to a steady-state coil assembly and a linear nuclear fusion device for a nuclear fusion device. Background Technology

[0002] A linear nuclear fusion device is an experimental device that uses magnetic confinement to achieve a controlled nuclear fusion reaction. For example, a field-inverse configuration (FRC) linear device mainly includes a vacuum chamber, magnetic field coils, a heating system, a feeding system, and a diagnostic system. A linear nuclear fusion device uses a magnetic field to confine a high-temperature plasma, so that the light nuclei (such as deuterium and tritium) can overcome the Coulomb repulsion between each other and approach to a sufficiently small distance, thereby causing a nuclear fusion reaction and releasing a large amount of energy.

[0003] Currently, linear nuclear fusion devices rely on the magnetic field generated by steady-state coil arrays to confine high-temperature plasma. These steady-state coil arrays are typically located around the outside of a vacuum chamber. The steady-state coil arrays are fixed to a base at the bottom, but these arrays are generally large and heavy, making it difficult to maintain stable stability for extended periods using only the base for constraint.

[0004] Therefore, existing technologies need to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the steady-state coil group is difficult to be stably fixed for a long time in the prior art. The purpose is to provide a steady-state coil group for nuclear fusion device and a linear nuclear fusion device, which adopts corresponding technical means and has the advantages of diverse fixing methods and good fixing effect.

[0006] This utility model is achieved through the following technical solution:

[0007] In a first aspect, this utility model provides a steady-state coil assembly for a nuclear fusion device, including a support base. The support base is provided with a plurality of steady-state coils, including a stabilizing rod, and also includes an upper U-shaped clamp and a lower U-shaped clamp that cooperate to clamp the steady-state coils. The upper U-shaped clamp is provided with a locking member that connects to the lower U-shaped clamp. After the upper U-shaped clamp and the lower U-shaped clamp are connected, the end of the stabilizing rod is fixed. The upper U-shaped clamp and the lower U-shaped clamp are provided with an insulating, non-magnetic, and anti-slip layer that contacts the steady-state coils.

[0008] Furthermore, in this utility model, the upper U-shaped clip and the lower U-shaped clip are respectively provided with an upper semi-circular hole and a lower semi-circular hole for the end of the stabilizing rod to be inserted.

[0009] Furthermore, in this utility model, a retaining plate is fixedly provided at the end of the stabilizer rod, and the upper U-shaped retainer and the lower U-shaped retainer are respectively provided with an upper half groove and a lower half groove for the end of the retaining plate to be inserted.

[0010] Furthermore, in this invention, the combined size and shape of the upper half-groove and the lower half-groove are the same as the size and shape of the card plate.

[0011] Furthermore, in this utility model, the aforementioned card plate is provided with a stud, and the end of the stabilizing rod is provided with a screw hole that mates with the stud.

[0012] Furthermore, in this invention, the aforementioned card plate is configured as a polygonal card plate, and the stabilizing rod is provided with a rotating part for rotation.

[0013] Furthermore, in this utility model, the locking component described above is configured as a bolt, and the upper U-shaped clip and the lower U-shaped clip are connected by the bolt.

[0014] Furthermore, in this utility model, the aforementioned upper U-shaped card and lower U-shaped card are disposed on the top and both sides of the top of the steady-state coil.

[0015] Furthermore, in this invention, the aforementioned insulating non-magnetic anti-slip layer is configured as a ceramic layer, and both the ceramic layer and the steady-state coil have a rough surface.

[0016] Secondly, this utility model also provides a linear nuclear fusion device, which employs the aforementioned steady-state coil group for nuclear fusion devices.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] This invention provides a steady-state coil assembly and a linear nuclear fusion device for a nuclear fusion apparatus. It mainly comprises three parts: an upper U-shaped clamp, a lower U-shaped clamp, and a stabilizing rod. During installation, the upper and lower U-shaped clamps approach the steady-state coils from the top and bottom, respectively, and are connected and fixed by locking components. The two ends of the stabilizing rod are clamped and fixed by the upper and lower U-shaped clamps locked on both sides. Connecting two adjacent steady-state coils via the upper and lower U-shaped clamps and the stabilizing rod fixes the tops of the two adjacent steady-state coils, making the overall structure of the steady-state coils more stable. Compared to traditional methods that rely solely on a base for fixation, this invention uses a support base and the upper and lower U-shaped clamps and stabilizing rod for fixation, offering more diverse fixing methods and a more stable fixing effect.

[0028] Example 1

[0029] This embodiment 1 provides a steady-state coil assembly for a nuclear fusion device, such as... Figures 1-5 As shown, the specific structure is described below.

[0030] Combination Figure 2 As shown, in existing linear nuclear fusion devices, the steady-state coil 2 is generally installed on the support base 1. Multiple steady-state coils 2 are distributed at intervals to form a steady-state coil group. The electromagnetic coil inside the steady-state coil 2 provides a suitable magnetic field for the linear nuclear fusion device to confine the plasma and promote the continuous and stable nuclear fusion reaction.

[0031] Furthermore, in combination Figure 1 and Figure 2 As shown, in order to keep the steady coil 2 stable for a long time, a U-shaped clip 3 and a lower U-shaped clip 4 are installed on the steady coil 2, and a stabilizing rod 6 is installed between the steady coils 2.

[0032] Combination Figure 3 and Figure 4 As shown, the cross-sections of the upper U-shaped clip 3 and the lower U-shaped clip 4 are both approximately U-shaped. The upper U-shaped clip 3 has a groove for securing the outer side of the steady-state coil 2, and the lower U-shaped clip 4 has a groove for securing the inner side of the steady-state coil 2. The upper U-shaped clip 3 and the lower U-shaped clip 4 are arranged in pairs to jointly wrap and secure the steady-state coil 2.

[0033] It should be noted that the upper U-shaped clip 3 and the lower U-shaped clip 4 are provided with aligned and connected mounting holes. After aligning the four mounting holes of the upper U-shaped clip 3 with the four mounting holes of the lower U-shaped clip 4, four locking pieces 5 are inserted to secure the connection. The locking pieces 5 are bolts, which make it very convenient to connect the upper U-shaped clip 3 and the lower U-shaped clip 4, and also make disassembly and maintenance relatively easy, resulting in good performance.

[0034] In some implementations of this embodiment, combined with Figure 3 and Figure 4 As shown, the stabilizer rod 6 is a round rod, so an upper semi-circular hole 301 is opened at the bottom of the upper U-shaped card 3, and a lower semi-circular hole 401 is opened at the top of the lower U-shaped card 4. When the upper U-shaped card 3 and the lower U-shaped card 4 are aligned and closed, the upper semi-circular hole 301 and the lower semi-circular hole 401 form a round hole for the stabilizer rod 6 to be inserted.

[0035] Furthermore, the size of the clamping plate 8 is larger than that of the stabilizer rod 6, and the clamping plate 8 is fixed to both ends of the stabilizer rod 6. An upper half-groove 302 is also formed at the bottom of the upper U-shaped clamp 3, which communicates with the upper semi-circular hole 301. A lower half-groove 402 is also formed at the top of the lower U-shaped clamp 4, which communicates with the lower semi-circular hole 401. When the upper U-shaped clamp 3 and the lower U-shaped clamp 4 are aligned and closed, the size and shape of the upper half-groove 302 and the lower half-groove 402 are the same as the size and shape of the clamping plate 8, forming a cavity to accommodate the clamping plate 8, facilitating the fixing of the ends of the stabilizer rod 6.

[0036] It should be noted that the upper U-shaped clip 3, the lower U-shaped clip 4, and the stabilizing rod 6 are all made of non-magnetic metal materials, such as non-magnetic stainless steel, which have the advantages of being sturdy and durable, and will not affect or be affected by magnetic fields.

[0037] When connecting, the lower U-shaped clip 4 is brought close to the steady-state coil 2, and then the clip plate 8 at the end of the stabilizer rod 6 is placed into the lower half groove 402 of the lower U-shaped clip 4. Finally, the upper U-shaped clip 3 is brought together with the lower U-shaped clip 4 from the outside of the steady-state coil 2 and fixed by the locking piece 5, thereby fixing the end of the stabilizer rod 6. The overall structure is simple and the fixing effect is good.

[0038] In some embodiments of this example, to make the upper U-shaped card 3 and the lower U-shaped card 4 more securely fixed, an insulating, non-magnetic, and anti-slip layer 7 is provided in the grooves of the upper U-shaped card 3 and the lower U-shaped card 4. The insulating, non-magnetic, and anti-slip layer 7 is made of ceramic layer, and the surface of the ceramic layer is set as an uneven rough surface. The fixed position of the corresponding steady-state coil 2 surface is also a rough surface. The rough surfaces are in contact with each other, which has a better anti-slip effect, and the upper U-shaped card 3 and the lower U-shaped card 4 are more securely fixed.

[0039] It should be noted that there are three locations on the steady-state coil 2 for the upper U-shaped card 3 and the lower U-shaped card 4 to securely connect them, namely the top of the steady-state coil 2 and the two sides of the top, which makes the overall structure of the steady-state coil assembly used in the nuclear fusion device more stable.

[0040] In this embodiment, combined with Figure 5 As shown, the clamping plate 8 is connected to the stabilizer bar 6 via a threaded connection. Specifically, a stud 801 is installed at the center of the end face of the clamping plate 8, and a threaded hole is formed at the end of the stabilizer bar 6. The stud 801 and the threaded hole are connected by a threaded connection. The clamping plate 8 can be polygonal in shape, such as a regular pentagon or a regular hexagon, and a rotating part is set in the middle of the stabilizer bar 6. Since the thread directions of the threaded holes at both ends of the stabilizer bar 6 are opposite, and the cross-section of the rotating part is a regular hexagon, by clamping the rotating part with calipers, when the stabilizer bar 6 is driven to rotate in one direction, the studs 801 at both ends gradually disengage from the threaded holes. When the stabilizer bar 6 is driven to rotate in the opposite direction, the studs 801 at both ends gradually insert into the threaded holes. This facilitates adjustment of the overall length of the stabilizer bar 6 and the clamping plate 8, making it more convenient to use.

[0041] Example 2

[0042] This embodiment 2 provides a linear nuclear fusion device, which uses the steady-state coil group for nuclear fusion devices in embodiment 1.

[0043] The working principle of the steady-state coil assembly and linear nuclear fusion device of this invention is as follows:

[0044] The steady-state coil set 2 for a linear nuclear fusion device and the linear nuclear fusion device mainly consist of three parts: an upper U-shaped clamp 3, a lower U-shaped clamp 4, and a stabilizing rod 6. During installation, the upper U-shaped clamp 3 and lower U-shaped clamp 4 approach the steady-state coil 2 from the top and bottom respectively, and are connected and fixed by locking components 5. The two ends of the stabilizing rod 6 are clamped and fixed by the upper U-shaped clamp 3 and lower U-shaped clamp 4 locked on both sides. The upper U-shaped clamp 3, lower U-shaped clamp 4, and stabilizing rod 6 connect two adjacent steady-state coils 2, thereby fixing the tops of the two adjacent steady-state coils 2, making the overall structure of the steady-state coil 2 more stable. Compared to the traditional method of fixing only with a base, this invention relies on a support base 1 and the upper U-shaped clamp 3, lower U-shaped clamp 4, and stabilizing rod 6 for fixing, providing more diverse fixing methods and a more stable fixing effect.

[0045] In summary, this utility model provides a steady-state coil assembly for a nuclear fusion device, including a support base 1.

The interior of the upper U-shaped clamp 3 and the lower U-shaped clamp 4 is provided with an insulating, non-magnetic, anti-slip layer 7 that contacts the steady-state coils 2. The upper U-shaped clamp 3 and the lower U-shaped clamp 4 are respectively provided with an upper semi-circular hole 301 and a lower semi-circular hole 401 for the end of the stabilizing rod 6 to be inserted. A clamping plate 8 is fixedly provided at the end of the stabilizing rod 6. The upper U-shaped clamp 3 and the lower U-shaped clamp 4 are respectively provided with an upper half-groove 302 and a lower half-groove 402 for the end of the clamping plate 8 to be inserted. The combined size and shape of the upper half-groove 302 and the lower half-groove 402 are the same as the size and shape of the clamping plate 8. The clamping plate 8 is provided with studs 801, and the end of the stabilizing rod 6 is provided with a screw hole that mates with the studs 801. The clamping plate 8 is configured as a polygonal clamping plate 8, and the stabilizing rod 6 is provided with a rotating part for rotation. The locking element 5 is configured as a bolt, and the upper U-shaped clamp 3 and the lower U-shaped clamp 4 are connected by bolts. The upper U-shaped clamp 3 and the lower U-shaped clamp 4 are provided on the top and both sides of the top of the steady-state coil 2.
