Technical Field

The invention relates to the technical field of superconducting power application, in particular to a force transmission device.

Background

The superconducting magnet has the advantages of large generated magnetic field, small volume, light weight, low loss and the like, and is often applied to the fields of ultrahigh-speed environments, such as ultrahigh-speed maglev trains, ultrahigh-speed electromagnetic ejection, high-speed three-dimensional reservoirs and the like. Taking a superconducting linear motor in an ultra-high-speed maglev train as an example, a superconducting magnet is used as a rotor part of the superconducting linear motor, and a magnetic field generated by the superconducting magnet interacts with a magnetic field generated by a stator part of the linear motor to generate huge thrust in the superconducting magnet, so that the superconducting magnet is rapidly pushed forward.

As is well known, the force generated by the interaction of a superconducting magnet with the magnetic field of an external coil is an electromagnetic force, and first acts on a superconducting coil within the superconducting magnet. How to transmit the electromagnetic force of the superconducting coil to an external vehicle body or other moving carriers so that the vehicle body and other moving carriers are subjected to the high-speed movement of the electromagnetic force transmitted by the superconducting coil is one of the core problems. Especially, in a limited superconducting magnet space and on the premise of light weight requirement of the superconducting magnet, the superconducting magnet needs to be provided with a force transmission device for transmitting the electromagnetic force of the superconducting coil to the moving carrier.

In most superconducting applications at present, the moving superconducting magnet is not limited by much weight and space, and the load borne by the superconducting magnet is not large, so that a specific electromagnetic force transmission device is not designed in the conventional superconducting magnet, a superconducting coil is directly connected with a superconducting magnet shell by adopting a supporting component, and the superconducting magnet is connected with an external moving carrier in a threaded connection or an embedded connection mode. As shown in fig. 1 (fig. 1 is a schematic diagram of force transmission of a conventional superconducting magnet in the prior art), a force transmission path of the superconducting magnet is that electromagnetic force of a superconducting coil is transmitted to a superconducting magnet housing through a supporting component, and then the electromagnetic force is transmitted to a moving carrier from the superconducting magnet housing through a bolt or other structural members, so that the moving carrier is forced to move.

The existing force transmission method is more conventional, most superconducting magnets adopt the scheme at present, but the mass and the space of the superconducting magnet are increased due to the fact that all the force transmission supporting components are placed inside the superconducting magnet, and the method is not generally suitable for the application with higher requirements on the mass and the space of the superconducting magnet, such as the fields of ultrahigh-speed maglev trains, supersonic electromagnetic emission and the like; in addition, the groove is directly formed in the moving carrier or the moving carrier is directly screwed, the requirements on the structural strength and the appearance of the moving carrier are high, the maintenance difficulty is high, and the long-time operation is generally difficult.

Fig. 2 is a schematic view of a force transfer device according to an embodiment of the invention.

The force transmission device can be applied to transmission of electromagnetic force of the super-high-speed superconducting magnet.

As shown in fig. 2, the embodiment of the present invention discloses a force transfer device, wherein the device comprises a superconducting skeleton 2 for supporting a superconducting coil 1, an inner dewar 3, a cold shield 4, an outer shell 5 and a force transfer rod 6, wherein,

the superconducting framework 2 provided with the superconducting coil 1 is arranged in the inner Dewar 3 and is connected with the inner Dewar 3 through a first connecting piece, a refrigerating medium is stored in the inner Dewar 3 and is used for cooling the superconducting coil 1, the cold screen 4 is arranged outside the inner Dewar 3, the dowel bar 6 sequentially penetrates through the inner Dewar 3 and the cold screen 4 from the center of the superconducting coil 1, is connected with the inner Dewar 3 and is not contacted with the cold screen 4, the shell 5 is arranged outside the cold screen 4 and is provided with an outer convex part matched with the dowel bar 6 extending out of the cold screen 4, the inner part of the outer convex part is connected with the dowel bar 6, the outer part of the outer convex part is connected with a motion carrier 7, a vacuum layer is arranged between the shell 5 and the inner Dewar 3, the cold screen 4 is connected with the inner Dewar 3 and the shell 5 through a second connecting piece, under the condition that the superconducting coil 1 and an external coil interact to generate electromagnetic force, the electromagnetic force of the superconducting coil 1 is transmitted to the moving carrier 7 sequentially through the superconducting framework 2, the first connecting piece, the inner Dewar 3, the dowel bar 6 and the outer shell 5.

Through the technical scheme, the superconducting coil can be arranged on the superconducting framework and placed in the inner Dewar, the cold screen is arranged outside the inner Dewar to prevent the superconducting coil from quenching and heat leakage, the dowel bar is arranged to sequentially penetrate through the inner Dewar and the cold screen from the center of the superconducting coil and is connected with the inner Dewar without contacting with the cold screen, the outer shell with the outer convex part matched with the dowel bar extending out of the cold screen is arranged outside the cold screen, and the outer convex part is connected with the motion carrier. Therefore, the superconducting coil can transmit force through the superconducting framework, the inner Dewar, the dowel bar and the shell, and finally the electromagnetic force of the superconducting coil is transmitted to the moving carrier, so that the moving carrier moves along with the force. Compared with the prior art, the force transmission device has fewer supporting parts, so that the superconducting magnet has a simple internal structure and a space margin, and the light-weight design of the high-load force transmission device can be realized in a very limited space.

In other words, the superconducting magnet transmission device combines electromagnetism and structural mechanics, is used for transmitting the electromagnetic force of the superconducting magnet in the ultra-high-speed and high-load environment, and finally can reliably transmit the electromagnetic force borne by the superconducting coil to the motion carrier through the force transmission device, so that the problem of transmitting the electromagnetic force of the superconducting magnet in the high-load and ultra-high-speed environment is solved.

The superconducting coil 1 is a core component of a superconducting magnet and is formed by winding a superconducting wire, and after excitation, a safe and reliable magnetic field can be generated and interacts with an external coil of the superconducting magnet to generate electromagnetic force.

For example, the first connecting member may be a bolt, and the superconducting framework 2 and the inner dewar 3 are fixedly connected by the bolt. The type and the number of the bolts can be determined according to the electromagnetic force borne by the superconducting coil, and the invention does not limit the type and the number. For example, 6-8 bolts above M10 may be used for fixation.

Wherein, the inner Dewar 3 can be a sealed container for storing the refrigeration medium. The refrigerant in the inner dewar 3 may cool the superconducting coil 1 to the operating temperature (77K for high temperature superconducting coils and below; 4.2K for low temperature superconducting coils). Meanwhile, as described above, the inner dewar 3 can transmit the force transmitted from the superconducting skeleton 2 to the force transmission rod.

For example, the refrigerant medium may be liquid helium, but the present invention is not limited thereto.

According to an embodiment of the invention, the second connection member may be a thin bolt, and the cold shield 4 is connected to the inner dewar 3 and the outer shell 5 through the thin bolt, respectively.

In the invention, the cold shield is not a force bearing device, so the cold shield can not be in direct contact with the dowel bar, for example, the size of an opening for penetrating through the dowel bar on the cold shield is set to be larger than that of the dowel bar, so that the dowel bar smoothly penetrates through the cold shield, and the direct contact between the cold shield and the dowel bar is avoided. And the thin bolt is only used for fixing the cold shield, so that the superconducting magnet is prevented from causing the cold shield to vibrate too much under a high-load and ultra-high-speed environment, and finally causing structural damage.

According to an embodiment of the invention, the shell 5 is also called an outer Dewar of the superconducting magnet, and a vacuum layer is arranged between the shell and the inner Dewar 3 to provide an ultrahigh vacuum environment for the superconducting magnet to operate, so that the heat conduction of air is reduced, and the consumption of a refrigerating medium and the heat load of a system are reduced; at the same time, the housing 5 can be used as a force bearing and transferring device, and the housing 5 will receive the force from the force transfer rod 6 and transfer the force to the motion carrier 7.

For the convex portion of the housing 5 (i.e. the portion of the housing 5 in contact with the force transmission rod 6, which is the main force-bearing position of the housing), the portion may be locally reinforced appropriately according to the magnitude of the transmission force, such as the convex portion is thickened. The inner part of the convex part of the outer shell 5 and the dowel bar 6 may be, for example, in a threaded connection, as shown in fig. 2, generally, the front end of the dowel bar is in a threaded connection (if the difficulty may be large during the assembly of the superconducting magnet, an embedded connection may also be adopted, and the specific connection mode may be determined according to the actual situation of the superconducting magnet), as can be easily seen from fig. 2, the outer shell 5 may simultaneously play a role in vacuum protection, and the vacuum of the outer shell is mainly concentrated among the inner dewar 3, the outer shell 5 and the dowel bar 6. The outer shell 5 is not in direct contact with the inner dewar 3 and the cold shield 4, which can reduce the heat leakage of the system.

The force transmission rod 6 is connected with the inner Dewar 3, the outer shell 5 and the motion carrier 7, bears the force from the superconducting framework 2, and simultaneously needs to transmit the force of the superconducting framework 2 to the outer shell 5 and finally to the motion carrier 7, so that the motion carrier is stressed to move.

Wherein, dowel bar 6 and interior dewar 3 can adopt threaded connection, and dowel bar 6 can not be with superconductive skeleton 2 direct contact. For example, in order to avoid direct contact, the dowel bar 6 may pass through a circular hole in the center of the superconducting skeleton 2 to be connected with the inner dewar 3; alternatively, the inner dewar 3 may have an outer convex portion capable of being embedded-connected to the superconducting former 2 through a circular hole in the center of the superconducting former 2, and the dowel bar 6 may be inserted into the outer convex portion of the inner dewar 3 to be connected to the outer convex portion (screw connection or embedded connection). The dowel bar 6 is a core component for bearing and transferring force, so the requirement on the material is high, the specific material can be determined according to the load requirement, and the titanium alloy and the G10 material can be generally used, but the invention is not limited to the material.

For example, but not limiting to the present invention, the threaded connection between dowel 6 and inner dewar 3 is preferably trapezoidal thread or fine thread to better secure with inner dewar 3.

Therefore, the engaging degree of the force transmission rod can be increased, and the force transmission rod is prevented from being damaged due to overlarge radial and axial forces of the force transmission rod at the ultra-high speed.

Fig. 3 is a schematic view of a buffer layer between a housing and a motion carrier according to an embodiment of the invention.

As shown in fig. 3, the device further comprises a buffer layer 8 arranged between the outer convex part of the outer shell 5 and the motion carrier 7.

In the actual moving process of the superconducting magnet and the moving carrier, the superconducting magnet or the moving carrier can generate random vibration due to the inevitable external mechanical disturbance. Therefore, by filling the buffer layer between the superconducting magnet shell and the moving carrier, when the superconducting magnet or the moving carrier generates random vibration, the relative displacement between the superconducting magnet and the moving carrier can be effectively reduced, the mechanical vibration caused by external mechanical interference is reduced, the vibration reduction effect is achieved, and the reliability and the safety of the system are improved.

For example, the buffer layer may be wrapped around the superconducting magnet housing, and then connected by interference fit, so that the housing and the surface of the moving carrier generate elastic pressure, thereby obtaining a tight connection.

According to an embodiment of the invention, the external part of the male part is screwed or embedded with the moving carrier 7.

The structural form of the motion carrier can be determined according to actual conditions, and after the force transfer rod transfers force to the motion carrier, the motion carrier is stressed to move together with the superconducting magnet. The moving carrier can adopt a high-strength non-magnetic material.

Fig. 4 is a cross-sectional view of a dowel according to an embodiment of the present invention.

As shown in fig. 4, one end of the dowel bar 6 on the superconducting coil 1 side is a hollow structure.

The dowel bar is used for connecting the inner Dewar and the moving carrier, namely, the temperature difference is directly from 77K (high-temperature superconducting coil) or 4.2K (low-temperature superconducting coil) to 300K at room temperature, so that the heat conduction of the dowel bar is one of main heat leakage of the superconducting magnet system. If the force transmission rod adopts a solid structure, the heat leakage of the system is very large, and a refrigerating medium (such as liquid helium) cannot be stored in the low-temperature superconducting magnet. Therefore, in order to reduce the heat conduction of the dowel bar and reduce the system heat leakage of the superconducting magnet, the dowel bar can be a partially hollow structure at the part with smaller bearing force, as shown in fig. 4. By arranging the hollow structure part, the weight of a part of the superconducting magnet can be reduced while the heat leakage of the system is reduced. In addition, the dowel bar can be further lengthened within a reasonable range, and heat leakage is reduced. According to the one-dimensional steady-state heat transfer equation of the dowel bar, the larger the hollow area of the dowel bar is, the longer the length of the dowel bar is, and the smaller the heat leakage of the dowel bar is. On one side of the moving carrier, the force transfer rod is stressed too much, so that a solid structure is needed.

According to an embodiment of the present invention, the superconducting coil 1 is wound on the superconducting former 2, and the superconducting coil 1 and the superconducting former 2 are fixed together by tension control and a subsequent curing process.

The superconducting coil 1 can be supported by arranging the superconducting framework 2, and the supporting function is realized during winding and curing, so that the structural strength of the superconducting coil is improved. Meanwhile, the electromagnetic force applied to the superconducting coil 1 can be transmitted to the inner Dewar 3.

According to an embodiment of the invention, the material of said superconducting former 2, said inner dewar 3 and said outer shell 5 is metal.

According to one embodiment of the invention, the metal is stainless steel (e.g., 316L stainless steel) or a titanium alloy.

The superconducting framework 2 adopts a high-strength non-magnetic material such as metal, and can better realize supporting and force transferring effects under the condition of not influencing a magnetic field generated by the superconducting coil.

Similar to the superconducting former, the inner dewar 3 may also be made of a high strength non-magnetic material such as metal to better achieve the force transfer.

Because the shell 5 is also a force bearing and transferring component, the shell can also be made of a high-strength non-magnetic material similar to the superconducting skeleton 2. If necessary, local reinforcement can be carried out at the position with serious stress according to actual conditions.

According to one embodiment of the invention, the material of the cold shield 4 is a high conductivity material.

According to one embodiment of the present invention, the high conductivity material may be silver, copper, or aluminum (e.g., high purity aluminum).

According to an embodiment of the present invention, the material of the buffer layer 8 is polytetrafluoroethylene or polystyrene.

It will be understood by those skilled in the art that the above description of the material of the buffer layer is merely exemplary and not intended to limit the present invention. Any filling material having characteristics such as good mechanical strength, excellent cushioning properties, easy molding, and strong temperature adaptability can be used as the cushion layer of the present invention.

Fig. 5 is a flow chart of force transfer between a superconducting coil and a moving carrier according to an embodiment of the present invention.

As shown in fig. 5, first, the magnetic field of the superconducting coil interacts with the magnetic field of the external coil, thereby generating an electromagnetic force in the superconducting coil; the superconducting coil and the superconducting framework are connected in a curing way, so that the force of the superconducting coil can be transmitted to the superconducting framework; the superconducting framework is connected with the inner Dewar through a bolt, for example, so that the force of the superconducting framework can be transmitted to the bolt and the inner Dewar; the inner Dewar is connected with the dowel bar by screw thread, so the force of the inner Dewar is transmitted to the dowel bar; the force-transmitting rod and the superconducting magnet housing can be connected by a thread, for example, so that the force can be transmitted to the external convex part of the housing, and the external convex part of the superconducting magnet housing and the motion carrier can be connected by a thread or an embedded connection, for example, so that the force of the housing can be transmitted to the motion carrier.

It can be seen from the above embodiments that the force transfer device of the present invention can be applied to transfer the electromagnetic force of the super-high-speed superconducting magnet, and when the superconducting magnet is in an environment of super-high speed, high load and high vibration, the force transfer device can effectively transfer the electromagnetic force of the superconducting coil to the moving carrier, and compared with the conventional method, the weight of the superconducting magnet can be reduced, the internal structure of the superconducting magnet can be simplified, and the volume of the superconducting magnet can be reduced.

In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures.
