Description

Technical Field

[0001] This utility model relates to the technical field of stellarators, and in particular to a support structure suitable for the vacuum chamber of a stellarator. Background Technology

[0002] Stellarator vacuum chambers are typically housed within a Dewar flask. During operation and baking, the vacuum chamber temperature can reach 200°C, while the outer Dewar temperature remains at room temperature. The vacuum chamber's shape within the Dewar is usually similar to that of plasma, supported by rigid supports and exhibiting a degree of torsion. Because the enclosed region directly undergoes fusion reactions, the high-temperature plasma generates significant radiant heat on its surface, typically reaching 150°C to 200°C. The vacuum chamber is usually fixed to the base of the main unit or the ground by a support structure, where the temperature is around 20°C. This large temperature gradient causes significant expansion and deformation of the vacuum chamber. However, current technologies using rigid supports to support the Dewar flask suffer from the problem that this deformation or displacement cannot be absorbed, potentially leading to damage to the vacuum chamber. Utility Model Content

[0003] The purpose of this invention is to solve the problem in the prior art that when a vacuum chamber is deformed or displaced by rigid support, it cannot be absorbed, which may cause damage to the vacuum chamber.

[0004] To solve the above-mentioned technical problems, the present invention discloses a support structure for the vacuum chamber of a stellarator, including a support device, the lower end of which is supported on a base, and the upper end of which passes through the Dewar of the stellarator and is fixedly connected to the vacuum chamber inside the Dewar.

[0005] The support device includes a rigid support part and a flexible support part connected in sequence in the height direction. The upper end of the rigid support part is fixedly connected to the vacuum chamber, and the lower end is fixed to the top of the flexible support part. The vacuum chamber can be moved and adjusted relative to the Dewar in the height direction, and the rigid support part can be moved relative to the base in the height direction.

[0006] The flexible support includes a movable support base, a support base, and a movable hinge that can move along the height direction. The support base is fixed on the base, the movable support base is movably disposed above the support base, and the movable hinge is disposed between the movable support base and the support base. The movable hinge includes a main hinge and a secondary hinge that are arranged side by side and spaced apart from each other.

[0007] The above technical solution employs a support device consisting of a rigid support and a flexible support. The upper end of the rigid support is in direct contact with and fixedly connected to the vacuum chamber, providing stable support. When the vacuum chamber experiences slight displacement or deformation due to thermal expansion and contraction or during operation, the displacement and deformation are transferred to the flexible support through the rigid support. The flexible support then deforms to absorb the displacement or deformation of the vacuum chamber. In other words, the rigid and flexible support work together to adapt to changes in the height dimension caused by thermal expansion and contraction, working displacement, and gravitational settlement of the vacuum chamber. Furthermore, it can buffer the deformation load and vibration of the vacuum chamber, effectively preventing deformation and damage to the vacuum chamber or support components due to stress concentration.

[0008] Furthermore, the movable hinge not only facilitates the vertical displacement adjustment of the movable support seat, absorbing the vertical deformation displacement of the vacuum chamber, but also utilizes the hinge's rotational freedom to adapt to minute angular deviations and lateral offsets, preventing the support structure from rigidly jamming and fully releasing structural constraint stress. The double hinges form a parallel support structure. On one hand, the vertical lifting and lowering of the movable support seat is achieved by the hinge's swing, absorbing the vertical deformation displacement of the vacuum chamber and releasing constraint stress; on the other hand, the double hinges work together to bear load, improving the overall load-bearing capacity while limiting large horizontal offsets of the movable support seat, resulting in higher structural strength and stability.

[0009] Furthermore, the rigid support is configured as a rigid support rod extending along the height direction, with the upper end of the rigid support rod fixedly connected to the vacuum chamber and the lower end fixedly connected to the movable support seat.

[0010] The above technical solution uses a rigid support rod arranged along the height direction to provide stable rigid support for the vacuum chamber and ensure the positioning accuracy of the vacuum chamber support. The lower end is connected to a vertically movable support seat, which compensates for displacement by moving the movable support seat along the height direction, absorbs the vertical displacement caused by the deformation of the vacuum chamber, and releases the constraint stress. The structure is simple, easy to install through the Dewar, and convenient for later debugging and maintenance.

[0011] Furthermore, the upper end of the movable hinge is movably hinged to the movable support seat, and the lower end is movably hinged to the support base.

[0012] Furthermore, the upper end of the main hinge is movably hinged to the lower end of the movable support, and the lower end is movably hinged to the upper end of the support base; the upper end of the secondary hinge is movably hinged to the lower end of the movable support, and the other end is movably hinged to the upper end of the support base.

[0013] Furthermore, the two ends of the main hinge and the secondary hinge are respectively hinged to the movable support and the support base via pins. Also, the main hinge and the secondary hinge extend at an angle relative to the height direction.

[0014] Using the above technical solution, the main hinge and the secondary hinge are arranged side by side at an angle, and the two ends are hinged by pins, forming a parallel support structure.

[0015] The present invention also discloses a support structure for a vacuum chamber of a stellarator. The flexible support part further includes a tension strut, the upper end of which is connected to a movable support seat and the lower end of which is connected to a support base.

[0016] Using the above technical solution, the tension strut connects the movable support base and the support base, and together with the main hinge and secondary hinge, forms a combined support structure. The tension strut can withstand tensile force, suppress the offset and sway of the flexible support part, and further improve the overall structural stability and load-bearing reliability.

[0017] Furthermore, the lower end of the rigid support is fixed to the top of the flexible support.

[0018] The top of the flexible support is provided with a positioning part, and the lower end of the rigid support has a positioning part that is adapted to the positioning part.

[0019] More preferably, the positioning part is configured as a positioning groove, and the positioned part is configured as a positioning protrusion adapted to the positioning groove. Furthermore, the positioning protrusion extends into the positioning groove and is detachably fixed by fasteners.

[0020] Using the above technical solution, the lower end of the rigid support and the flexible support are adapted through the positioning part and the positioned part, which makes the installation simple and convenient and the positioning accurate, avoiding uneven force on the vacuum chamber due to misalignment of the support docking.

[0021] The present invention also discloses a support structure for a vacuum chamber of a stellarator, wherein the Dewar is provided with a through hole for a rigid support to pass through, and the diameter of the through hole is larger than the outer diameter of the rigid support.

[0022] A flexible connecting part is also provided on the outside of the rigid support part. One end of the flexible connecting part is fixed to the rigid support part, and the other end is fixedly connected to the periphery of the through hole.

[0023] More preferably, the flexible connection part is a corrugated pipe, which is sleeved on the outside of the rigid support part. One end of the corrugated pipe is fixedly connected to the outer peripheral wall of the rigid support part, and the other end is fixedly connected to the peripheral outer wall of the through hole and seals and covers the through hole.

[0024] Using the above technical solution, the diameter of the Dewar's through-hole is larger than the outer diameter of the rigid support, reserving a movement clearance for the rigid support and preventing rubbing interference between the rigid support and the Dewar when it moves. The bellows, fitted outside the rigid support, seals both ends of the rigid support and the periphery of the through-hole, sealing the through-hole and maintaining a sealed environment inside the Dewar. The bellows itself is expandable and can deviate slightly, maintaining sealing performance while moving with the rigid support without restricting the vertical deformation and displacement of the vacuum chamber, thus balancing dynamic movement compensation and vacuum sealing requirements. The structure is compact and easy to maintain.

[0025] In summary, this utility model discloses a support structure for the vacuum chamber of a stellarator. The support device for the vacuum chamber is configured as a rigid support and a flexible support connected sequentially in the height direction. The rigid support provides stable support to the vacuum chamber. When the vacuum chamber experiences small displacements or deformations, the displacement and deformation are transferred to the flexible support through the rigid support, and absorbed by the flexible support. Therefore, this utility model, through the cooperation of the rigid and flexible support, adapts to changes in the height dimension of the vacuum chamber caused by thermal expansion and contraction, working displacement, and gravitational settling.

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0043] This embodiment discloses a support structure for the vacuum chamber of a stellarator. Please refer to [link to relevant documentation]. Figure 1 The support structure includes a support device 100, the lower end of which is supported on the base, and the upper end passes through the dewar 200 of the stellarator and is fixedly connected to the vacuum chamber 300 inside the dewar 200.

[0044] It should be noted that the upper and lower ends of the support device 100 refer to their relative positions. In this embodiment, the installation positions of the stellarator's Dewar 200 and vacuum chamber 300 are taken as the reference. The upper and lower ends of the support device 100 refer to the upper and lower ends in the height direction. The upper end is fixedly connected to the vacuum chamber 300. The upper end of the support device 100 can be fixedly connected by welding, snap-fitting, bolting or other methods.

[0045] The lower end of the support device 100 is supported on the base. Similarly, the specific structure of the base is not limited. For example, the base can be a separately set support structure, or the base can be a support platform, or the base can be the bottom surface. The support device 100 and the base can also be fixedly connected by welding, snap-fitting, bolting or other methods.

[0046] See also Figure 1 The support device 100 includes a rigid support part 110 and a flexible support part 120 connected in sequence in the height direction. The upper end of the rigid support part 110 is fixedly connected to the vacuum chamber 300 and the lower end is fixed to the top of the flexible support part 120. The vacuum chamber 300 can be moved and adjusted relative to the Dewar 200 in the height direction, and the rigid support part 110 can be moved relative to the base in the height direction.

[0047] Specifically, in this embodiment, the specific structures of the rigid support portion 110 and the flexible support portion 120 are not limited. The rigid support portion 110 can be a support rod, a threaded rod, or a telescopic rigid support rod; the flexible support portion 120 can be a high-elasticity rubber flexible support structure, a flexible spring support structure, a movable hinge support structure, etc. For example, the rigid support portion 110 can be a support rod, and the flexible support portion 120 can be a high-elasticity rubber flexible support structure. One end of the support rod is fixed to the vacuum chamber 300, and the other end is fixedly connected to the high-elasticity rubber flexible support structure. The movement or displacement of the vacuum chamber 300 can be transmitted to the high-elasticity rubber flexible support structure through the support rod. Alternatively, for example, the rigid support portion 110 can be a support rod, and the flexible support portion 120 can be a flexible spring support structure. One end of the support rod is fixed to the vacuum chamber 300, and the other end is fixedly connected to the flexible spring support structure. The movement or displacement of the vacuum chamber 300 can be transmitted to the flexible spring support structure through the support rod.

[0048] In this structural design, the support device 100 employs a combination of a rigid support portion 110 and a flexible support portion 120. The upper end of the rigid support portion 110 is in direct contact with and fixedly connected to the vacuum chamber 300, providing stable support for the vacuum chamber 300. When the vacuum chamber 300 experiences slight displacement or deformation due to thermal expansion and contraction or during operation, the displacement and deformation are transferred to the flexible support portion 120 through the rigid support portion 110. The flexible support portion 120 deforms to absorb the displacement or deformation of the vacuum chamber 300. In other words, the rigid support portion 110 and the flexible support portion 120 work together to adapt to changes in the height dimension of the vacuum chamber 300 caused by thermal expansion and contraction, working displacement, and gravitational settlement. Furthermore, they can buffer the deformation load and vibration of the vacuum chamber 300, effectively preventing deformation and damage to the vacuum chamber 300 or the support components due to stress concentration.

[0049] For more details, please see Figure 1 as well as Figure 2 The flexible support 120 includes a movable support base 121, a support base 122, and a movable hinge 130 that can move along the height direction. The support base 122 is fixed to the base, the movable support base 121 is movably disposed above the support base 122, and the movable hinge 130 is disposed between the movable support base 121 and the support base 122. Furthermore, the movable hinge 130 includes a main hinge 131 and a secondary hinge 132 arranged side-by-side and spaced apart from each other.

[0050] With this structural design, the movable hinge 130 not only facilitates the vertical displacement adjustment of the movable support 121, absorbing the vertical deformation displacement of the vacuum chamber 300, but also utilizes the hinge's rotational freedom to adapt to minute angular deviations and lateral offsets, preventing the support structure from rigidly jamming and fully releasing structural constraint stress. The two hinges form a parallel support structure. On one hand, the hinges swing to achieve vertical lifting and lowering of the movable support 121, absorbing the vertical deformation displacement of the vacuum chamber 300 and releasing constraint stress; on the other hand, the two hinges work together to bear load, improving the overall load-bearing capacity while limiting large horizontal offsets of the movable support 121, resulting in higher structural strength and stability.

[0051] Further, please see Figure 1 as well as Figure 4 The rigid support part 110 is configured as a rigid support rod extending along the height direction. The upper end of the rigid support rod is fixedly connected to the vacuum chamber 300, and the lower end is fixedly connected to the movable support seat 121.

[0052] With this structural design, the rigid support rod is arranged along the height direction, which can provide stable rigid support for the vacuum chamber 300 and ensure the positioning accuracy of the vacuum chamber 300. The lower end is connected to the vertically movable support seat 121. The displacement compensation is achieved by moving the movable support seat 121 in the height direction, absorbing the vertical displacement caused by the deformation of the vacuum chamber 300, and releasing the constraint stress. The structure is simple, easy to install through the Dewar 200, and convenient for later debugging and maintenance.

[0053] Further, please see Figure 1 and Figure 2 The upper end of the movable hinge 130 is movably hinged to the movable support 121, and the lower end is movably hinged to the support base 122.

[0054] For details, please see Figure 1 and Figure 2 In this embodiment, the movable support 121 and the support base 122 are arranged opposite to each other. The support base 122 is fixedly connected to the base, and the movable support 121 is fixedly connected to the rigid support rod. A movable hinge 130 is provided between the movable support 121 and the support base 122. The upper end of the movable hinge 130 is movably hinged to the movable support 121, and the lower end is movably hinged to the support base 122. In this way, when the rigid support rod undergoes relative displacement along the height direction, it will first transmit the relative displacement to the movable support 121. At this time, the movable hinge 130 will move or rotate to absorb the displacement of the rigid support rod. However, the rigid support rod still provides rigid support for the vacuum chamber 300, and the support base 122 is also fixedly connected to the base.

[0055] Further, please see Figure 2The upper end of the main hinge 131 is movably hinged to the lower end of the movable support 121, and the lower end is movably hinged to the upper end of the support base 122; the upper end of the secondary hinge 132 is movably hinged to the lower end of the movable support 121, and the other end is movably hinged to the upper end of the support base 122.

[0056] Furthermore, the two ends of the main hinge 131 and the secondary hinge 132 are movably hinged to the movable support 121 and the support base 122 respectively via pins 133. Also, the main hinge 131 and the secondary hinge 132 extend at an angle relative to the height direction.

[0057] With this design, the main hinge 131 and the secondary hinge 132 are arranged side by side at an angle, and the two ends are hinged by the pin 133.

[0058] Furthermore, when the main hinge 131 and the secondary hinge 132 are tilted, they can provide a reaction force. The core purpose is to provide a centering restoring force, stabilize the balance, and adapt to the radial thermal expansion and contraction of the vacuum chamber.

[0059] This embodiment also discloses a support structure for the vacuum chamber of a stellarator; please refer to [link to relevant documentation]. Figure 2 and Figure 3 The flexible support part 120 also includes a tension strut 123, the upper end of which is connected to the movable support seat 121 and the lower end of which is connected to the support base 122.

[0060] The tension strut 123 connects the movable support 121 and the support base 122, and together with the main hinge 131 and the secondary hinge 132, forms a combined support structure. The tension strut 123 can withstand tension, suppress the offset and sway of the flexible support part 120, and further improve the overall structural stability and load-bearing reliability.

[0061] Further, please see Figure 1 and Figure 2 The lower end of the rigid support 110 is fixed to the top of the flexible support 120. The top of the flexible support 120 is provided with a positioning part, and the lower end of the rigid support 110 has a positioning part that is adapted to the positioning part.

[0062] Specifically, the specific structure of the positioning part and the positioned part is not limited. For example, the positioning part can be a positioning groove and the positioned part can be a positioning boss; or, the positioning part can be a conical positioning groove and the positioned part can be a conical boss; or, the positioning part can be a positioning pin hole and the positioned part can be a positioning pin. Those skilled in the art can design or select according to actual needs, and this embodiment does not make specific limitations in this regard.

[0063] Preferably, please refer to the following: Figure 1 , Figure 2 as well as Figure 4The positioning part is configured as a positioning groove 124, and the positioned part is configured as a positioning protrusion 111 that is adapted to the positioning groove 124. Furthermore, the positioning protrusion 111 extends into the positioning groove 124 and is detachably fixedly connected by a fastener 125. In this embodiment, the fastener 125 is not limited, and can be, for example, a bolt, a pin, a screw, etc. In this embodiment, the fastener is preferably a high-strength bolt or a nut.

[0064] With this structural design, the lower end of the rigid support 110 and the flexible support 120 are adapted through the positioning part and the positioned part, making installation simple, convenient and accurate, and avoiding uneven stress on the vacuum chamber 300 due to misalignment of the support docking.

[0065] This embodiment also discloses a support structure for the vacuum chamber of a stellarator; please refer to [link to relevant documentation]. Figure 4 The Dewar 200 is provided with a through hole 210 through which the rigid support part 110 passes. The diameter of the through hole 210 is larger than the outer diameter of the rigid support part 110.

[0066] A flexible connecting part is also provided on the outside of the rigid support part 110. One end of the flexible connecting part is fixed to the rigid support part 110, and the other end is fixedly connected to the periphery of the through hole 210.

[0067] The specific structure of the flexible connection is not limited. For example, it can be a corrugated pipe 140, a flexible plastic pipe, a flexible rubber pipe, etc. The flexible connection can seal the through hole 210 and can also generate relative displacement of the auxiliary rigid support 110 in the height direction.

[0068] See also Figure 1 and Figure 4 For example, when the vacuum chamber 300 moves in the height direction due to thermal expansion and contraction or other reasons, the vacuum chamber 300 will transmit the displacement in the height direction to the rigid support rod. When the rigid support rod transmits the displacement to the flexible support part 120, the movable hinge part 130 of the flexible support part 120 will move and deform. For example, the main hinge 131 and the secondary hinge 132 will tilt and rotate, thereby causing the lower end of the rigid support rod to move in the height direction. However, when the main hinge 131 and the secondary hinge 132 tilt and rotate, deflection will occur. Since the diameter of the hole 210 is larger than the outer diameter of the rigid support part 110, interference between the rigid support part 110 and the Dewar 200 can be avoided.

[0069] It should be noted that, for example, when the operating temperature of the vacuum chamber 300 is 100°C and the baking temperature is 200°C, thermal expansion will occur, and the movable hinge 130 of the flexible support 120 allows the rigid support rod to be displaced in the height direction.

[0070] Preferably, please refer to Figure 1 and Figure 4The flexible connection part is a corrugated pipe 140, which is sleeved on the outside of the rigid support part 110. One end of the corrugated pipe 140 is fixedly connected to the outer peripheral wall of the rigid support part 110, and the other end is fixedly connected to the peripheral outer wall of the through hole 210 and seals and covers the through hole 210.

[0071] In this design, the diameter of the through hole 210 of the Dewar 200 is larger than the outer diameter of the rigid support 110, providing a clearance for the rigid support 110 to prevent friction and interference between the rigid support 110 and the Dewar 200 during displacement. The bellows 140, fitted outside the rigid support, seals both ends of the rigid support 110 and the periphery of the through hole 210, sealing the through hole 210 and maintaining a sealed environment inside the Dewar 200. The bellows 140 is expandable and can slightly shift, maintaining a continuous seal while moving with the rigid support 110 without restricting the vertical deformation and displacement of the vacuum chamber 300, thus balancing dynamic motion compensation and vacuum sealing requirements. The structure is compact and easy to maintain.

[0072] In summary, this utility model discloses a support structure for the vacuum chamber of a stellarator. The support device 100 of the vacuum chamber 300 of the stellarator is configured as a rigid support portion 110 and a flexible support portion 120 connected sequentially in the height direction. The rigid support portion 110 provides stable support for the vacuum chamber 300. When the vacuum chamber 300 experiences small displacement or deformation, the displacement and deformation are transferred to the flexible support portion 120 through the rigid support portion 110, and absorbed by the flexible support portion 120. Therefore, this utility model, through the cooperation of the rigid support portion 110 and the flexible support portion 120, adapts to changes in the height dimension of the vacuum chamber 300 caused by thermal expansion and contraction, working displacement, and gravitational settlement.

[0073] More specifically, the vacuum chamber undergoes a baking / operation temperature range from room temperature to 150-200°C during operation, creating a significant temperature difference with the base (room temperature). Thermal expansion and contraction result in substantial displacement, generating extremely high thermal stress in the vacuum chamber shell and support structure. In this embodiment, the support device with this structure avoids problems such as fatigue cracking and weld failure under long-term cyclic loading. Furthermore, it can accommodate multi-directional thermal deformation. The double-hinge structure employs a compact design, simultaneously achieving load-bearing, thermal compensation, positioning, and limiting functions within a limited space. It adapts to the complex spatial layout of the stellarator, solving the problems of large space occupation and interference with coils inherent in traditional support structures.
