Description

Technical Field

[0001] This utility model relates to the field of accelerator power supply technology, and in particular to a fastening device for hot-swappable standard modules of accelerator standardized power supplies. 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] Most existing accelerator power supplies have moved towards modularization, but the modularization of power supplies from different manufacturers is carried out independently, without a unified standard. There are no standardized specifications for module interfaces, communication protocols, dimensions, current and voltage specifications, and power specifications, making modules from different manufacturers incompatible and non-replaceable. This has a certain impact and limitation on the design, production, operation, maintenance, upgrades, expansion, and procurement of accelerator power supplies, increasing costs and restricting the flexibility, scalability, reliability, and availability of accelerator power supply systems. Standardization of accelerator power supplies aims to unify the shape, size, electrical interfaces, and communication protocols of different functional modules, forming standards. These standard modules can then be flexibly combined to create power supplies of different types and specifications for accelerators, meeting the requirements of future generations of accelerators for highly reliable, highly available, and easily maintainable power supplies. Standard modules with different functions include current modules, voltage modules, energy dissipation modules, energy storage modules, H-bridge modules, forced excitation modules, and scanning modules of various specifications. These standard modules are interconnected and operate together in a standard water-cooled cabinet through a designed structure. Meanwhile, most of these standard modules employ high-efficiency, high-power-density converters, resulting in relatively high output power and generating significant heat during operation. Reliable and effective cooling is essential to ensure long-term stable operation. Existing cooling systems primarily utilize air or liquid cooling, typically requiring a fixed connection between the cooling system and the heat-generating components of the standard module. Because the water and electrical circuits are integrated for plugging and unplugging, the connection structure between the standard module and the cooling system becomes complex, installation and removal operations are cumbersome, and rapid module replacement is difficult. Furthermore, standard modules often weigh over 10 kilograms, making installation and removal inconvenient. Therefore, a fastening device capable of quickly clamping and separating the standard module from the cooling system is urgently needed. Utility Model Content

To this end, this invention proposes a fastening device for hot-swappable standard modules of accelerator standardized power supplies, thereby achieving the goal of separating and standardizing the liquid cooling structure from the standard module, simplifying the loading and unloading operations of the standard module, and improving the stability of the standard module.

[0021] According to the present invention, a fastening device for a hot-swappable standard module for a standardized power supply of an accelerator is provided, which further includes a panel disposed at the front end of the standard module. After the rear end of the standard module is connected to the hot-swappable connector, the panel is attached to the water-cooling plates on both sides of the standard module.

[0023] According to the present invention, a fastening device for hot-swappable standard modules of accelerator standardized power supply is provided, which further includes a latch disposed on the handle.

[0028] The screw is threadedly connected to the first wedge block. Rotating the screw causes the blocking block to move closer to the first wedge block, which in turn drives the second wedge block to move toward the standard module.

Furthermore, 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.

[0047] With the continuous development of accelerator technology, those skilled in the art have recognized high reliability, high efficiency, and high availability as trends in accelerator development. Modularization of accelerator power supplies has always been a goal pursued, and standardizing power supply modules can further promote accelerator development.

[0048] Currently, the standard module 600 of the accelerator power supply generates a significant amount of heat during operation, requiring reliable and effective cooling to ensure long-term stable operation. However, existing cooling devices primarily employ either air cooling or liquid cooling. When air cooling is used, it is typically housed within the standard module, resulting in a bulky and complex structure. When liquid cooling is used, it is usually housed in a water-cooled cabinet, with cooling achieved through close contact between the standard module 600 and the cooling device. However, existing water-cooled cabinets often only have cavities for inserting the standard module, preventing a tight fit between the standard module and the cooling device and hindering efficient heat exchange.

[0049] To ensure a tight seal between the standard module 600 and the cooling unit, thereby efficiently transferring the heat generated during operation to the cooling unit and ensuring long-term stable and reliable operation of the standard module 600, and to ensure that the standard module 600 can be hot-swapped for easy upgrades and maintenance, technicians have installed fastening devices in the accelerator's water-cooled cabinet to ensure a tight fit between the standard module and the cooling unit.

[0050] like Figure 1 and Figure 2 As shown in the embodiments of this utility model, the fastening device is described in detail.

[0051] The fastening device mainly includes the cabinet base 100, the cabinet back panel 200, and the water-cooled plate 300.

[0052] A guide rail 110 is provided on the rack base 100. The top of the guide rail 110 protrudes from the upper surface of the rack base 100, allowing the bottom of the standard module 600 to directly contact the guide rail 110. A hot-swappable connector 210 is provided on the rack back panel 200 for hot-swappable electrical connection with the standard module 600. Studs 220 are provided on the rack back panel 200.

[0053] The water-cooled plate 300 has an internal liquid circulation pipeline. Meanwhile, the rack back panel 200 has a connecting pipe that communicates with the liquid circulation pipeline. During operation, cooling water first flows into the rack back panel 200, and then enters the liquid circulation pipeline of the water-cooled plate 300 through the connecting pipe, keeping the water-cooled plate 300 at a low temperature for cooling the standard module 600.

[0054] Specifically, the water-cooled plate 300 is perpendicularly connected to the cabinet base 100 along the length of the guide rail 110. The cabinet back panel 200 is perpendicularly connected to the water-cooled plate 300 via studs 220.

[0055] Two water-cooled plates 300 are spaced apart on both sides of the guide rail 110 and form grooves with the cabinet back panel 200 and the cabinet base 100. Furthermore, one of the two water-cooled plates 300 is provided with a pressing component 400 for tightly attaching the standard module 600 to the other water-cooled plate 300.

[0056] Furthermore, the extrusion assembly 400 includes a plurality of elastically deformable tabs 410. The tabs 410 are mounted on the side of one water-cooled plate 300 to abut against the standard module 600, pressing it firmly against another water-cooled plate 300. This ensures close contact between the standard module 600 and the water-cooled plate 300, thereby efficiently transferring the heat generated during operation to the water-cooled plate 300, ensuring stable and reliable long-term operation of the standard module 600.

[0057] In this embodiment, by setting the extrusion component 400 in the fastening device, the standard module can be constrained in multiple directions to ensure that the standard module 600 is in close contact with the water-cooled plate 300. This allows the heat generated by the standard module 600 during operation to be conducted to the water-cooled plate 300 through the contact surface for efficient heat dissipation. This ensures that the standard module 600 can work stably and reliably for a long time, while also facilitating hot-swappable replacement, upgrades, and maintenance.

[0058] Based on the above embodiments, another embodiment of this utility model introduces a fastening device for hot-swappable standard modules of accelerator standardized power supplies.

[0059] The spring piece 410 includes at least a fixing part 411 and a deformable part 412. The fixing part 411 is used to connect with the water-cooled plate 300. After the fixing part 411 of the spring piece 410 is connected with the water-cooled plate 300, the deformable part 412 extends out of the outside of the water-cooled plate 300 and can reciprocate relative to the water-cooled plate 300.

[0060] In this way, when the standard module 600 is installed in place, the hot-swappable connector on the standard module 600 is fully connected to the hot-swappable connector 210 on the rack back panel 200. At the same time, the deformable part 412 is abutted by the standard module 600 and deformed, so that the spring piece 410 has elasticity and can push the standard module 600 to fit tightly against the water-cooled plate 300 on the other side, so that the standard module 600 and the water-cooled plate 300 can carry out efficient heat conduction, thereby ensuring that the standard module 600 will not loosen or shift during operation, and enhancing the stability of the standard module 600.

[0061] Based on the above embodiments, another embodiment of this utility model introduces a fastening device for hot-swappable standard modules of accelerator standardized power supplies.

[0062] like Figure 2 As shown, the deformable portion 412 of the spring piece 410 is configured as an arc-shaped curved surface. The fixing portion 411 of the spring piece 410 is configured as a plane. The two fixing portions 411 are located at the two ends of the deformable portion 412, making the spring piece 410 arched.

[0063] Furthermore, the fastening device also includes surface-treated strips. These surface-treated strips are respectively disposed on the contact surfaces of the spring and the standard module to improve surface strength and scratch resistance.

[0064] Based on the above embodiments, another embodiment of this utility model introduces a fastening device for hot-swappable standard modules of accelerator standardized power supplies.

[0065] To avoid collisions between the spring sheet 410 and the standard module 600 during loading and unloading, the arrangement of the spring sheet 410 on the water-cooled plate 300 in the extrusion assembly 400 is optimized.

[0066] A plurality of the aforementioned spring pieces 410 are arranged in an array along the horizontal and vertical directions on the water-cooled plate 300. Furthermore, both ends of the spring pieces 410 are connected to the water-cooled plate 300 along the horizontal direction, so that the length direction of the spring pieces 410 is consistent with the movement direction of the standard module 600.

[0067] In this way, when the standard module 600 moves along the guide rail 110, interference and collision between the deformable part 412 of the spring piece 410 and the rear end of the standard module 600 can be avoided, so that the deformable part 412 is gradually deformed by the side pressure of the standard module 600.

[0068] In this embodiment, by setting a spring-type extrusion component 400 in the fastening device, the problems of project delays and low installation efficiency caused by processing errors and installation errors during mass production and assembly of the fastening device are solved. This ensures the precision of the assembly of the standard module 600 and the water-cooled cabinet in the accelerator project and improves the project progress and installation efficiency of mass production and assembly of the fastening device.

[0069] Based on the above embodiments, another embodiment of this utility model introduces a fastening device for hot-swappable standard modules of accelerator standardized power supplies.

[0070] To facilitate heat transfer and cooling, the fastening device also includes a thermally conductive material. This thermally conductive material is disposed between the water-cooled plate 300 and the standard module 600, and between the spring contact 410 and the standard module 600. In this way, the heat generated by the standard module 600 can be quickly transferred to the water-cooled plate 300 via the thermally conductive material, and then dissipated through the heat dissipation device of the water-cooled plate 300, thereby greatly improving heat exchange efficiency.

[0071] Based on the above embodiments, another embodiment of this utility model introduces a fastening device for hot-swappable standard modules of accelerator standardized power supplies.

[0072] like Figure 1 and Figure 3 As shown, to reduce the friction between the standard module 600 and the cabinet base 100, in one configuration, the guide rail 110 is provided with two rows of rotatable ball bearings 111. The upper ends of the ball bearings 111 protrude from the top surface of the guide rail 110 and are used for rolling connection with the standard module 600.

[0073] Furthermore, a number of the ball bearings 111 are evenly distributed on the top surface of the guide rail 110, allowing the standard module 600 to slide easily on the guide rail 110, greatly reducing the force required to install and remove the standard module 600.

[0074] In another case, such as Figure 4 As shown, the guide rail 110 is provided with nylon pads 112. Two nylon pads 112 protrude from the top surface of the guide rail 110. The nylon pads 112 extend to the cabinet back panel 200 along the moving direction of the standard module 600, and are used for frictional contact with the standard module 600, thereby simplifying the structure of the guide rail 110 and further increasing the installation space of the standard module 600.

[0075] In this embodiment, the guide rail 110 reduces the friction between the standard module 600 and the cabinet base 100, making the loading and unloading of the standard module 600 easier. The fastening device can promote the modular development of the accelerator power supply.

[0076] Based on the above embodiments, another embodiment of this utility model introduces a fastening device for hot-swappable standard modules of accelerator standardized power supplies.

[0077] To ensure that the standard module 600 does not loosen or shift during operation and to improve the stability and reliability of the standard module 600, the fastening device also includes a panel 610 located at the front end of the standard module 600.

[0078] The rear end of the standard module 600 is positioned by a hot-swappable connector 210. After the rear end of the standard module 600 is connected to the hot-swappable connector 210, the panel 610 is attached to the water-cooled plates 300 on both sides of the standard module 600.

[0079] Furthermore, the fastening device also includes a handle 620. The handle 620 is provided on the panel 610 to facilitate assisted pulling of the standard module 600.

[0080] Furthermore, it also includes a latch 630 disposed on the handle. When the standard module 600 is inserted into the fastening device and connected to the hot-swappable connector 210, the latch 630 forms a barbed connection with the cabinet baffle 500 to prevent the standard module 600 from loosening and exiting.

[0081] Based on the above embodiments, another embodiment of this utility model introduces a fastening device for hot-swappable standard modules of accelerator standardized power supplies.

[0082] like Figure 5As shown, the extrusion assembly 400 includes a screw 420, a first wedge block 430, and a second wedge block 440. The contact surface between the second wedge block 440 and the first wedge block 430 is inclined to the axial direction of the screw 420. The contact surfaces of two adjacent second wedge blocks 440 are also inclined to the axial direction of the screw 420.

[0083] A plurality of blocking blocks 421 are provided on the outer peripheral surface of the screw 420. The blocking blocks 421 are distributed axially at intervals from one end of the screw 420.

[0084] Several first wedge-shaped blocks 430 are fixed to the water-cooling plate 300. Furthermore, the first wedge-shaped blocks 430 and the blocking blocks 421 are spaced apart and correspond one-to-one. A plurality of second wedge-shaped blocks 440 are disposed between the first wedge-shaped blocks 430 and the blocking blocks 421. Figure 5 As shown, in order to make the blocking block 421 stably abut against the first wedge block 430, the first wedge block 430 is set near the blocking block 421 with one end face set as a plane perpendicular to the screw 420.

[0085] The screw 420 is threadedly connected to the first wedge block 430. Rotating the screw 420 causes the blocking block 421 to move closer to the first wedge block 430, which can drive the second wedge block 440 to move towards the standard module 600.

[0086] Additionally, the extrusion assembly 400 is mounted on the water-cooled plate 300. The extrusion assembly 400 is parallel to the guide rail 110. One end of the screw 420 passes through the water-cooled plate 300. The panel 610 of the standard module 600 has a through hole corresponding to the position of the screw 420 for rotation operation.

[0087] When the standard module 600 is not installed in the fastening device, the second wedge blocks 440 in the extrusion assembly 400 are all located inside the side wall of the water-cooled plate, so that the standard module 600 can be inserted into the fastening device.

[0088] After the standard module 600 is installed into the fastening device, the screw 420 is rotated through the through hole on the panel 610, causing the blocking block 421 to move towards the first wedge block 430. Consequently, the second wedge block 440, located between the blocking block 421 and the first wedge block 430, is compressed, moves radially along the screw 420, and protrudes from the side wall of the water-cooled plate 300. The second wedge block 440 compresses and pushes the standard module 600 to press firmly against the water-cooled plate 300 on its other side. Further, the compression assembly 400 can also be configured to consist of a screw 420, a fixed wedge block, and a movable wedge block. The movable wedge block is slidably connected to the fixed wedge block.

[0089] The fixed wedge block is mounted on the water-cooled plate 300. The screw 420 is rotatably mounted on the water-cooled plate 300 and is provided with a blocking pressure block for pressing the movable wedge block to move relative to the fixed wedge block.

[0090] Along the axial direction of the screw 420, the movable wedge block is located between the blocking block and the fixed wedge block. The contact surface between the movable wedge block and the fixed wedge block is inclined to the axial direction of the screw 420.

[0091] The blocking block is provided with a threaded hole that mates with the screw 420. Rotating the screw 420 to move the blocking block closer to or away from the fixed wedge block can drive the movable wedge block to move toward the standard module 600.
