Description

Technical Field

[0001] This utility model relates to the field of accelerator power supply technology, and in particular to an aid for disassembling and hot-swapping standard modules. Background Technology

[0002] In the rapid development of modern science and technology, accelerator technology, as a cutting-edge field of interdisciplinary collaboration, is undergoing profound changes. From its initial role as a tool for basic research to its current widespread application in many key industries such as medicine, energy, and materials science, accelerators have become an important force driving progress in various fields.

[0003] With the continuous expansion and deepening of application demands, high reliability, high efficiency, and high availability have become inevitable trends in the development of next-generation accelerators. In the medical field, proton accelerators used for precision cancer treatment require stable operation to ensure the accuracy of each treatment dose, which relies heavily on a highly reliable power supply. In energy exploration, accelerator-based nuclear waste transmutation projects aim to convert long-lived radioactive waste into short-lived or stable nuclides to solve the problem of long-term nuclear waste storage, requiring an efficient power supply to maintain the accelerator's long-term, high-intensity operation. High-intensity heavy ion accelerators, as large-scale scientific research facilities for exploring the deep structure of matter and the mysteries of cosmic evolution, have extremely high requirements for power supply availability; any brief power failure could lead to the loss of experimental data or even damage to the equipment.

[0004] In the future, superconducting linear accelerators are planned to adopt standardized power supply solutions in major projects such as isotope production based on accelerators, nuclear waste transmutation treatment, and high-intensity heavy ion accelerators. For a long time, modularization of accelerator power supplies has been a relentless pursuit in the industry. Modular design enables rapid replacement and maintenance of power supply components, improving system maintainability and flexibility. Standardizing power supply modules goes a step further, promoting interchangeability between power supply modules from different manufacturers, reducing R&D, production, and maintenance costs; facilitating the establishment of unified quality standards and testing specifications, significantly improving power supply reliability and stability; and accelerating the application of new technologies, promoting the coordinated development of the entire accelerator industry, thus laying a solid foundation for continuous innovation and breakthroughs in accelerator technology.

[0005] Accelerator standardized power supplies achieve different types and specifications of power by combining various standard modules within a standard water-cooled cabinet. These standard modules include standard current modules, standard voltage modules, energy dissipation modules, and energy storage modules. In accelerator standardized power supplies, the secure installation and removal structure of the hot-swappable standard modules based on a water-electricity separation architecture plays a crucial role.

[0006] However, inserting or removing hot-swappable standard modules into or from rack slots often presents challenges such as inconvenience, the need for significant pulling force, and the risk of loosening during removal. Traditional disassembly methods are not effectively suited to the unique structure of standard modules, resulting in inefficient installation and removal processes and potentially damaging the modules, thus affecting the use of the accelerator's standardized power supply. Utility Model Content

[0007] This invention aims to solve at least one of the technical problems existing in the related art. To this end, this invention proposes an auxiliary tool for facilitating the disassembly of hot-swappable standard modules. In addition to preventing the standard module from loosening and being pulled out when it is inserted, this auxiliary tool can also reduce the pulling force required to separate the standard module from the rack slot, thereby improving the efficiency of loading and unloading standard modules.

[0008] This utility model provides an aid for facilitating the disassembly of hot-swappable standard modules. The aid includes:

[0009] The mounting bracket is installed on the panel of the standard module;

[0010] The handle is provided with a gripping part that is rotatably connected to the fixed base;

[0011] Clips are used to hook onto the cabinet baffle to prevent standard modules from loosening and coming out;

[0012] Wherein, one end of the buckle is installed on the handle, the other end of the buckle passes through the panel, and the buckle has a first position for hooking onto the cabinet baffle and a second position for disengaging from the cabinet baffle;

[0013] The handle is provided with a pressing part protruding from the outside of the fixed base, and the grip part is located inside the fixed base and forms a lever structure with the pressing part that can swing back and forth relative to the fixed base, which is used to convert the pulling force applied to the grip part into the pushing force of the pressing part on the cabinet baffle.

[0014] The handle includes a groove provided in the grip portion, the groove being adjacent to the pressing portion;

[0015] One end of the buckle is installed in the groove, so that the buckle swings between a first position and a second position as the handle rotates.

[0016] According to the present invention, a puller for facilitating the disassembly of a hot-swappable standard module further includes a rivet installed on the fixed base, and the gripping part is provided with a through hole for rotatable connection with the rivet.

[0017] The through hole penetrates the side wall of the groove, and the rivet passes through the through hole and is rotatably connected to the buckle.

[0018] According to the present invention, a hot-swappable standard module removal aid is provided, which further includes an elastic element disposed in the groove, one end of the elastic element abutting against the side wall of the groove, and the other end of the elastic element abutting against the buckle.

[0019] According to the present invention, a hot-swappable standard module removal aid is provided, wherein the mounting base includes two parallel spaced plates, the plates being perpendicular to the panel, and the handle being rotatably mounted between the two plates.

[0020] According to the present invention, a hot-swappable standard module removal aid is provided, wherein the fixing base is detachably connected to the panel.

[0021] According to the present invention, a pull-out aid for easy disassembly of a hot-swappable standard module is provided, wherein the groove is provided with an arc-shaped concave surface extending downward to the bottom of the groove for installing the buckle;

[0022] The through hole is aligned with the central axis of the concave arc surface, and the end of the buckle is a convex arc surface with a radius smaller than that of the concave arc surface.

[0023] According to the present invention, an aid for disassembling and hot-swappable standard modules is provided, wherein the central axis of the arc concave surface is lower than the bottom of the groove.

[0024] According to the present invention, a hot-swappable standard module removal aid is provided, wherein the gripping part is configured as a ring structure, which is composed of an arched section and a chord-shaped section connected end to end;

[0025] The pressing part extends from the end of the chord segment and protrudes from the fixing seat along the length direction of the chord segment.

[0026] According to the present invention, an auxiliary device for disassembling and hot-swappable standard modules is provided. The other end of the buckle is provided with an arc-shaped guide surface. During the process of inserting the standard module into the rack slot, the rack baffle slides into contact with the guide surface and pushes the buckle to rotate to the second position.

[0027] The above-mentioned one or more technical solutions of this utility model have at least one of the following technical effects: The standard modules of the accelerator standardized power supply are usually heavy, usually more than 10 kg. After being inserted into the rack slot, due to system installation errors, the tight engagement of hot-swappable connectors, the pressing of several fastening springs, and the pressing friction with the water-cooling plate, the standard module is subjected to great resistance when it is pulled out. At the same time, the standard module may loosen and come out due to thermal stress, vibration and other factors during operation. Therefore, this technical solution designs a rigid movable structure with sufficient strength that is easy to install on the standard module, which facilitates the insertion of the standard module. At the same time, it has a lever structure, which allows the pulling force applied to the grip to be proportionally increased when the standard module is pulled out, so that a greater pushing force is applied to the rack baffle through the pressing part, which greatly reduces the pulling force required when the standard module is pulled out. This makes it convenient and quick to install and remove the heavy standard module, improving the operating efficiency.

[0028] Meanwhile, the pull-out aid is also equipped with a latch that hooks onto the cabinet baffle. When the handle is pulled, the latch can automatically disengage from the baffle, and when reinserted, it automatically resets under the action of a spring. This facilitates the insertion of standard modules and prevents them from loosening and coming out abnormally during operation, thus securing the standard modules.

[0029] In addition to the technical problems solved by this utility model, the technical features of the technical solutions constituted by this utility model, and the advantages brought about by these technical features, as described above, other technical features of this utility model and the advantages brought about by these technical features will be further explained in conjunction with the accompanying drawings, or can be learned through the practice of this utility model.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0045] With the continuous development of accelerator power supply technology, those skilled in the art have set high reliability, high efficiency, and high availability as the goals pursued by accelerator power supplies, and the standardization of accelerator power supplies has become an inevitable trend. Standardized accelerator power supplies provide various types and specifications of power to accelerators through the flexible combination of standard modules of different types and specifications. Standard module 600 is an important component of standardized accelerator power supplies, typically including standard current modules, standard voltage modules, and energy dissipation modules. Standardizing accelerator power supplies can greatly promote the development of accelerator power supply technology. In standardized accelerator power supplies, the fastening and disassembly structure of the hot-swappable standard module 600 based on a water-electricity separation structure plays a crucial role.

[0046] However, inserting or removing the standard module 600 from the rack slot 700 often presents problems such as inconvenience, the need for significant pulling force, and the risk of loosening or falling off. Traditional disassembly methods cannot effectively accommodate the special installation structure of the standard module 600, resulting in low efficiency in installing and removing it, and potentially damaging the module, thus affecting the use of the accelerator's standardized power supply.

[0047] To address these challenges, engineers optimized the structure of the pull-out aid used for hot-swappable standard modules. After each optimization, engineers fabricated experimental components corresponding to the structural changes. These experimental components were then assembled onto the pull-out aid, and experiments were conducted to detect any defects in the aid.

[0048] Technicians have made multiple improvements to the design of each component of the extraction aid and solved problems such as difficulty in assembling parts, high processing costs, and easy damage to the structure. In the end, the extraction aid with a standard module that is easy to disassemble and hot-swap was developed in this utility model.

[0049] like Figures 1 to 7 As shown in the embodiments of this utility model, the pull-out aid is described in detail.

[0050] The accelerator rack slot 700 has a receiving cavity. The standard module 600 is embedded in the receiving cavity and is detachably connected to the rack slot 700. A pull-out aid is provided on the panel 610 of the standard module 600 to reduce the pulling force required to separate the standard module 600 from the rack slot 700.

[0051] The pull-out aid mainly includes a mounting base 100, a handle 200, and a latch 300. A cabinet baffle 710 is installed on the cabinet slot 700. The cabinet baffle 710 has a notch for engaging with the latch 300. The panel 610 of the standard module 600 also has a notch running through the front and back of the panel 610, allowing the handle 200 and the latch 300 to pass through.

[0052] The mounting base 100 is mounted on the panel 610 of the standard module 600. The handle 200 has a gripping part 210 that is rotatably connected to the mounting base 100. The buckle 300 is used to hook onto the cabinet baffle 710 to prevent the standard module 600 from loosening and retracting.

[0053] Specifically, one end of the latch 300 is attached to the handle 200. The other end of the latch 300 passes through the panel 610. The latch 300 has a first position for engaging with the cabinet baffle 710 and a second position for disengaging from the cabinet baffle 710.

[0054] like Figure 5As shown, the handle 200 is provided with a pressing part 220 protruding from the outside of the fixed base 100. The grip part 210 is located inside the fixed base 100, and the grip part 210 and the pressing part 220 form a lever structure that can swing back and forth relative to the fixed base 100, which is used to convert the pulling force applied to the grip part 210 into the pushing force of the pressing part 220 on the cabinet baffle 710.

[0055] When removing the standard module 600 from the rack slot 700, the operator applies a pulling force to the grip 210, causing the handle 200 to rotate relative to the fixed base 100. Simultaneously, the pressing part 220 causes the latch 300 to disengage from the rack slot 700, and the pressing part 220 pushes against the rack baffle 710, separating the standard module 600 from the rack slot 700.

[0056] Furthermore, the handle 200 is made of high-strength materials, which can withstand greater stress and ensure that it will not break during disassembly and removal, such as stainless steel.

[0057] In this embodiment, by optimizing the structure of the handle 200 to make it a lever structure, the pulling force applied to the grip 210 can be proportionally increased, and then a larger pushing force can be applied to the cabinet baffle 710 through the pressing part 220. This significantly reduces the pulling force required to pull the standard module 600 out of the accelerator's cabinet slot 700, thereby facilitating and quickly installing and removing the standard module 600 and improving operational efficiency.

[0058] Based on the above embodiments, another embodiment of this utility model introduces an aid for facilitating the disassembly of hot-swappable standard modules.

[0059] like Figure 6 and Figure 7 As shown, the handle 200 includes a groove 211 disposed in the grip portion 210. The groove 211 is adjacent to the pressing portion 220.

[0060] One end of the buckle 300 is installed in the groove 211, and is used to make the buckle 300 swing between a first position and a second position as the handle 200 rotates.

[0061] Furthermore, the puller also includes a rivet 400 mounted on the fixed base 100. The gripping part 210 is provided with a through hole 212 that is rotatably connected to the rivet 400.

[0062] The through hole 212 penetrates the side wall of the groove 211. The rivet 400 passes through the through hole 212. Furthermore, the rivet 400 is rotatably connected to the buckle 300.

[0063] Furthermore, the pull-out aid also includes an elastic element 500 disposed within the groove 211. One end of the elastic element 500 abuts against the sidewall of the groove 211. The other end of the elastic element 500 abuts against the buckle 300.

[0064] like Figure 6 As shown, a groove 211 is provided on the bottom surface of the handle 200. A through hole 212 penetrates the side wall of the groove 211 and is located at the left end of the groove 211. When the latch 300 is in the first position, the left side wall of the latch 300 is in contact with the left side wall of the groove 211. The elastic element 500 is disposed between the right side wall of the latch 300 and the right side wall of the groove 211. When a pushing force is applied to the latch 300 to make it rotate clockwise, the elastic element 500 can push the latch 300 to rotate counterclockwise to return to the first position after the pushing force disappears.

[0065] In this embodiment, a buckle 300 is provided on the handle 200 to hook onto the rack baffle 710. When the handle 200 is pulled, the buckle 300 can automatically disengage from the rack baffle 710. When the standard module 600 is inserted into the rack slot 700, the buckle 300 automatically returns to the position hooked onto the rack baffle 710 under the action of elasticity. This facilitates the insertion of the standard module 600 and also prevents the standard module 600 from abnormally loosening and exiting the rack slot 700 during operation, thus providing a fastening effect for the standard module 600.

[0066] Based on the above embodiments, another embodiment of this utility model introduces an aid for facilitating the disassembly of hot-swappable standard modules.

[0067] The mounting base 100 includes two parallel, spaced-apart flat plates 110. The flat plates 110 are perpendicular to the panel 610. The handle 200 is rotatably mounted between the two flat plates 110.

[0068] like Figure 5 As shown, a cabinet baffle 710 is installed on the accelerator's cabinet slot 700. The standard module 600 has a notch on its panel 610 that runs through the front and back of the panel 610. A clip 300 passes through the notch and hooks onto the cabinet baffle 710.

[0069] When the handle 200 rotates clockwise relative to the fixed base 100, the pressing part 220 passes through the notch. The pressing part 220 causes the buckle 300 to disengage from the cabinet baffle 710. The pressing part 220 pushes the cabinet baffle 710 to separate the standard module 600 from the cabinet slot 700.

[0070] Furthermore, the mounting base 100 is detachably connected to the panel 610.

[0071] Based on the above embodiments, another embodiment of this utility model introduces an aid for facilitating the disassembly of hot-swappable standard modules.

[0072] As shown in the figure, the groove 211 is provided with an arcuate concave surface extending downwards to the bottom of the groove, which is used to install the buckle 300.

[0073] The through hole 212 is aligned with the central axis of the concave arc surface. The end of the buckle 300 is a convex arc surface. Furthermore, the radius of the convex arc surface is smaller than the radius of the concave arc surface, thereby allowing the buckle 300 to rotate smoothly relative to the handle 200.

[0074] Furthermore, the central axis of the arc concave surface is lower than the bottom of the groove 211, so that the contact point between the elastic element 500 and the buckle 300 is always located above the rotation center of the buckle 300, which can stably apply a torque to the buckle 300 to restore it to the first position.

[0075] Based on the above embodiments, another embodiment of this utility model introduces an aid for facilitating the disassembly of hot-swappable standard modules.

[0076] To facilitate the application of pulling force by the operator, the grip 210 is configured as a ring structure, consisting of an arched segment and a chord segment connected end to end.

[0077] The pressing part 220 extends from the end of the chord segment along the length direction of the chord segment and protrudes from the fixing base 100.

[0078] Furthermore, to prevent the buckle from colliding and being damaged by the cabinet baffle, the other end of the buckle 300 is provided with an arc-shaped guide surface.

[0079] During the process of inserting the standard module 600 into the rack slot 700, the rack baffle 710 slides into contact with the guide surface and pushes the buckle 300 to rotate to the second position.

[0080] Based on the above embodiments, another embodiment of the present invention introduces a standard module 600 for a standardized power supply for accelerators.

[0081] The standard module 600 is equipped with the extraction aid described in any of the above embodiments. A panel 610 is provided at the front end of the standard module 600. The extraction aid includes a fixing base 100, a handle 200, and a buckle 300. The fixing base 100 is mounted on the panel 610. The panel 610 has a notch extending through the front and rear of the panel 610, allowing the handle 200 and the buckle 300 to pass through.

[0082] When the standard module 600 is installed in the rack slot 700, the operator applies a pulling force to the handle 200, causing the handle 200 to rotate relative to the fixing base 100. Simultaneously, this causes the latch 300 to disengage from the rack baffle 710, making it easy to separate the standard module 600 from the rack slot 700. This significantly reduces the pulling force required to remove the standard module 600 from the rack slot 700, facilitating the installation and removal of the standard module 600.

[0083] In addition, the pull-out aid is equipped with a latch 300 that hooks onto the rack baffle 710. When the standard module 600 is disassembled, the latch 300 simultaneously disengages from the rack baffle 710; when inserted into the rack slot 700, the latch 300 automatically returns to the position hooked onto the rack baffle 710 under the action of spring force. This facilitates the insertion of the standard module 600 and also prevents the standard module 600 from abnormally loosening and exiting the rack slot 700 during operation, thus providing a secure fastening effect for the standard module 600.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.

[0085] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
