[0001] This application relates to the field of reactor technology, and more particularly to a reactor protection system. Background Technology

[0002] In related technologies, the limited installation space inside the cabinet of the reactor protection system makes it difficult to install Ethernet hubs on the mounting plate inside the cabinet. Summary of the Invention

[0003] In view of this, embodiments of this application aim to provide a reactor protection system capable of installing an Ethernet hub.

[0004] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0005] This application discloses a reactor protection system, including:

[0006] A server rack includes a cabinet body, a first mounting plate, and a second mounting plate. The cabinet body forms a receiving cavity, and the front surface of the server rack forms an operation port communicating with the receiving cavity. The first mounting plate and the second mounting plate are disposed within the receiving cavity and are spaced apart along the front-back direction. The thickness direction of the first mounting plate and the thickness direction of the second mounting plate are both parallel to the front-back direction. The first mounting plate has an original mounting area, and the original mounting area forms a first mounting hole.

[0007] The conversion plate has a second mounting hole.

[0008] An Ethernet hub is mounted on the conversion board;

[0009] Fasteners, at least a portion of which pass through the first mounting hole and the second mounting hole.

[0010] In one embodiment, the conversion plate has an opening groove extending through the end of the conversion plate along a first direction, and the second mounting hole communicates with the opening groove. The fastener can enter or exit the second mounting hole through the opening groove, wherein the first direction is perpendicular to the thickness direction of the conversion plate.

[0011] In one embodiment, the fastener includes a screw and a nut, the portion of the screw extending out of the first mounting hole and the second mounting hole engaging with the nut threadedly.

[0012] In one embodiment, the reactor protection system includes a fastener, the conversion plate has a first positioning hole located on the side of the second mounting hole away from the edge along a second direction, the Ethernet hub has a second positioning hole, and at least a portion of the fastener passes through the first positioning hole and the second positioning hole to fix the Ethernet hub and the conversion plate, wherein the second direction is perpendicular to the thickness direction of the conversion plate.

[0013] In one embodiment, the portion of the conversion plate near the side of the first mounting plate is recessed to form a recessed groove, the recessed groove surrounding the outer periphery of the first positioning hole, the fixing member including a head and a connecting portion, the head being connected to the connecting portion, the connecting portion passing through the first positioning hole and the second positioning hole, the head being located in the recessed groove, and the surface of the head away from the connecting portion not higher than the surface of the conversion plate near the first mounting plate.

[0014] In one embodiment, the number of the first mounting holes, the number of the second mounting holes, and the number of the fasteners are all two. The two first mounting holes are spaced apart along the second direction, and each fastener passes through the corresponding first mounting hole and the second mounting hole.

[0015] In one embodiment, the projection of the Ethernet hub on the first mounting plate is located within the original mounting area, and the first mounting hole is located on the outer periphery of the projection of the Ethernet hub on the first mounting plate.

[0016] In one embodiment, the distance between the first mounting plate and the second mounting plate is between 6 cm and 8 cm; and / or,

[0017] Both the first mounting plate and the second mounting plate are located in the lower half of the cabinet; and / or,

[0018] The first mounting plate has a hand-accommodating space below it, and the hand-accommodating space is connected to the area between the first mounting plate and the second mounting plate.

[0019] In one embodiment, the reactor protection system includes wires and electrical components disposed around the periphery of the original installation area.

[0020] In one embodiment, the Ethernet hub has a power socket formed on its side along the second direction for connecting to a power source.

[0021] This application discloses a reactor protection system that utilizes the original mounting area of ​​a first mounting plate. By setting up a conversion board, an Ethernet hub can be installed in the original mounting area of ​​the first mounting plate. This addresses several issues: Firstly, due to the complexity of the reactor protection system, the numerous structural components within the cabinet, and the limited space for installing Ethernet hubs, directly mounting a new Ethernet hub onto the first mounting plate would require redesigning the first mounting plate and altering the layout of other structural components within the cabinet, resulting in high design costs and significant design difficulty. Therefore, this application utilizes a conversion board to mount the Ethernet hub into the original mounting area of ​​the first mounting plate. This allows any type of Ethernet hub, whether existing or new, to be compatible with the first mounting plate without requiring a redesign. This solves the problem of incompatible installation of various Ethernet hubs at a low cost. Secondly, placing the Ethernet hub in the original mounting area avoids the need to re-route power cables, network cables, and fiber optic cables connected to the Ethernet hub, saving time and effort. By forming a first mounting hole in the original mounting area and a second mounting hole in the conversion board, and using fasteners to pass through the first and second mounting holes, the connection strength between the conversion board and the first mounting board can be improved, reducing the possibility of the Ethernet hub on the conversion board falling off, and ensuring good operational stability.

Detailed Implementation

[0029] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0030] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. The terms "first," "second," etc., used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In the relevant technology, it is necessary to replace the old Ethernet hub 200 originally used in the reactor protection system. The new Ethernet hub has not only changed in appearance compared to the old Ethernet hub 200, but also in its installation method, making it impossible to install in the original installation area. If it is installed in other places, the power lines, network cables and optical fibers connected to the Ethernet hub will need to be re-wired, which is quite difficult to implement.

[0032] In view of this, embodiments of this application provide a reactor protection system, please refer to... Figures 1 to 5The reactor protection system includes a cabinet 1, a conversion board 2, an Ethernet hub 3, and fasteners. The cabinet 1 includes a cabinet body 11, a first mounting plate 12, and a second mounting plate 13. The cabinet body 11 forms a receiving cavity 11a. The front surface of the cabinet 1 forms an operating port 11b communicating with the receiving cavity 11a. The first mounting plate 12 and the second mounting plate 13 are disposed within the receiving cavity 11a. The first mounting plate 12 and the second mounting plate 13 are spaced apart along the front-back direction. The thickness direction of the first mounting plate 12 and the thickness direction of the second mounting plate 13 are both parallel to the front-back direction. The first mounting plate 12 has an original mounting area 12b, and the original mounting area 12b forms a first mounting hole 12b1.

[0033] It should be noted that the original installation area 12b refers to the installation area of ​​the original Ethernet hub 3. In other words, it is the area on the first mounting plate 12 that is empty after the original Ethernet hub 3 has been removed.

[0034] Here, the Ethernet hub 3 can be used to connect multiple devices together to enable communication and data transmission between the devices.

[0035] In this way, by forming a receiving cavity 11a inside the cabinet 11, the first mounting plate 12, the second mounting plate 13 and the Ethernet hub 3 can be protected inside the cabinet 11 to improve their service life.

[0036] The converter plate 2 has a second mounting hole 2a. The Ethernet hub 3 is disposed on the converter plate 2. At least a portion of the fastener passes through the first mounting hole 12b1 and the second mounting hole 2a.

[0037] The reactor protection system provided in this application embodiment utilizes the original mounting area 12b of the first mounting plate 12. By setting a conversion plate 2, the Ethernet hub 3 can be installed on the original mounting area 12b of the first mounting plate 12. This addresses the challenges of a complex reactor protection system with numerous structural components and limited space for installing the Ethernet hub 3 within the cabinet 1. Directly mounting the new Ethernet hub onto the first mounting plate 12 would require redesigning the first mounting plate 12 and altering the layout of other structural components within the cabinet 1, resulting in high design costs and significant design difficulty. Therefore, this application utilizes a conversion plate 2... The adapter board 2 is used to mount the Ethernet hub 3 to the original mounting area 12b of the first mounting board 12. This allows any type of Ethernet hub 3, such as an existing one or a new one, to be compatible with the first mounting board 12 without requiring a redesign of the board. This solves the problem of incompatibility between various Ethernet hubs 3 at a low cost. Furthermore, placing the Ethernet hub 3 in the original mounting area 12b avoids the need to re-route power cables, network cables, and fiber optic cables connected to the Ethernet hub 3, saving time and effort. By forming a first mounting hole 12b1 in the original mounting area 12b and a second mounting hole 2a on the adapter board 2, and using fasteners to pass through the first and second mounting holes 12b1 and 2a, the connection strength between the adapter board 2 and the first mounting board 12 is improved, reducing the likelihood of the Ethernet hub 3 falling off the adapter board 2 and ensuring good operational stability.

[0038] It should be noted that the first mounting plate 12 is located near the operating port 11b, and the second mounting plate 13 is located in the receiving cavity 11a on the side of the first mounting plate 12 away from the operating port 11b.

[0039] For example, the reactor could be a nuclear reactor used as a neutron source.

[0040] As an example, in one embodiment, please refer to Figure 2 and Figure 3The old Ethernet hub 200 has a third mounting hole 200a, and the original mounting area 12b has a fourth mounting hole. A first fastener passes through the third mounting hole 200a and the fourth mounting hole to complete the connection between the old Ethernet hub 200 and the first mounting plate 12. Here, the first mounting hole 12b1 can be the fourth mounting hole on the first mounting plate 12 that connects to the old Ethernet hub 200, and the fastener can be the first fastener used to fix the old Ethernet hub 200. In this way, on the one hand, by using the original first mounting hole 12b1 and the fastener on the first mounting plate 12, the layout of the first plate body does not need to be redesigned, saving time and effort; on the other hand, by using the original first mounting hole 12b1 and the fastener, the fastener can directly cooperate with the first mounting hole 12b1 after passing through the second mounting hole 2a, which is convenient, efficient, and easy to install.

[0041] In one embodiment, the fastener includes a screw and a nut, with the portion of the screw extending out of the first mounting hole 12b1 and the second mounting hole 2a engaging with the nut's thread. This allows for several advantages: firstly, the tightness of the connection can be adjusted by changing the tightness of the nut, adapting to different usage environments and requirements; secondly, the screw-nut connection is more compact and robust, with a more uniform force-bearing area. Compared to a single screw connection, this eliminates the need for tapping the first mounting hole 12b1 and the second mounting hole 2a, allowing them to be directly set as through holes, which is convenient and efficient. Furthermore, it can withstand greater force than a single screw, resulting in a more secure connection. Thirdly, the screw-nut connection is easier to disassemble; simply loosening the nut allows for screw removal, facilitating later maintenance and replacement. Finally, screws and nuts can be used for a wider range of sheet metal connections, including those made of different materials, making them convenient and practical.

[0042] As an example, in one embodiment, please refer to Figure 1 The cabinet 11 includes a front panel 111, a rear panel 112, two side panels 113, a top panel 114, and a bottom panel 115. The top panel 114 and the bottom panel 115 are spaced apart in the vertical direction. The two side panels 113, the rear panel 112, and the front panel 111 are connected around the top panel 114 and the bottom panel 115 to jointly define the receiving cavity 11a. The front panel 111 is used to open or close the operating port 11b.

[0043] In one embodiment, the distance between the first mounting plate 12 and the second mounting plate 13 is 6cm to 8cm. For example, the distance between the first mounting plate 12 and the second mounting plate 13 can be 6cm, 7cm or 8cm. In this way, by setting an appropriate distance, the internal integration of the cabinet 11 can be improved.

[0044] As an example, in one embodiment, please refer to Figure 1The shape of cabinet 11 is not limited. For example, the shape of cabinet 11 can be a cuboid, specifically: 160cm high and 60cm wide.

[0045] For example, in one embodiment, the first mounting plate 12 can be a 4U system auxiliary area (SRV) mounting plate, and the second mounting plate 13 can be an Ai / Di input and Ao (wiring) area mounting plate.

[0046] As an example, in one embodiment, please refer to Figure 1 The cabinet 1 includes multiple mounting plates, such as channel AI mounting plate 14, system logic area mounting plate 15, Ap / Tp mounting plate 16, channel logic output mounting plate 17, and LCD mounting plate 18, which are located above the first mounting plate 12 and the second mounting plate 13, respectively, to avoid structural interference.

[0047] In one embodiment, please refer to Figure 1 The first mounting plate 12 and the second mounting plate 13 are both located in the lower half of the cabinet 1. For example, the first mounting plate 12 and the second mounting plate 13 may be disposed in the receiving cavity 11a near the bottom plate 115.

[0048] In one embodiment, please refer to Figure 1 The first mounting plate 12 has a hand-receiving space 12a below it, which communicates with the area between the first mounting plate 12 and the second mounting plate 13. For example, a hand-receiving space 12a is formed between the first mounting plate 12 and the base plate 115. Thus, when installing the conversion plate 2, one hand can pass the screw through the first mounting hole 12b1 and the second mounting hole 2a and hold it in place, while the other hand reaches into the area between the first mounting plate 12 and the second mounting plate 13 from the hand-receiving space 12a to tighten the nut, thereby fixing the conversion plate 2.

[0049] In one embodiment, please refer to Figure 5 The conversion plate 2 has an opening slot 2b extending through its end in a first direction. For example, the first direction can be vertical; for instance, the opening slot 2b extends downwards through the end of the conversion plate 2. A second mounting hole 2a communicates with the opening slot 2b, allowing fasteners to enter or exit the second mounting hole 2a through the opening slot 2b. The first direction is perpendicular to the thickness direction of the conversion plate 2. Thus, when installing the Ethernet hub 3, it is not necessary to completely remove the screws and nuts. Simply loosen the screws after tightening them, so that the screw protrudes from the side of the first mounting plate 12 away from the second mounting plate 13. Then, align the opening slot 2b on the conversion plate 2 with the protruding part of the screw and insert it into the second mounting hole 2a. Finally, tighten the screws and nuts to complete the installation and replacement of the Ethernet hub 3.

[0050] It should be noted that you should refer to [link / reference]. Figure 2 The old Ethernet hub 200, lacking the opening slot 2b, required the entire assembly (including screws and nuts) to be installed and removed during installation and disassembly. Since the old hub itself occupied space, the already limited handspace 12a became even smaller, requiring only one or two fingers to reach the area between the first mounting plate 12 and the second mounting plate 13, relying on touch to operate the screws and nuts. This embodiment, by providing the opening slot 2b, makes installing and replacing the Ethernet hub 3 much more convenient and faster than with the old hub 200, eliminating the difficulty of relying solely on touch. Furthermore, compared to redesigning the internal layout, cabling, and first mounting plate 12 of the cabinet 1, creating the opening slot 2b on the conversion plate 2 significantly reduces design difficulty and cost, preventing reactor malfunctions caused by redesign and improving reactor operational stability.

[0051] In one embodiment, please refer to Figure 3 and Figure 5 The system has two first mounting holes 12b1, two second mounting holes 2a, and two fasteners. The two first mounting holes 12b1 are spaced apart along a second direction, and each fastener passes through a corresponding first mounting hole 12b1 and second mounting hole 2a. For example, the second direction can be left-right, with the two first mounting holes 12b1 spaced apart along the second direction and the two second mounting holes 2a spaced apart along the left-right direction. Each first mounting hole 12b1 is aligned with one second mounting hole 2a, and each fastener passes through one first mounting hole 12b1 and one second mounting hole 2a. This further enhances the connection strength between the conversion board 2 and the first mounting plate 12, thereby improving the operational stability of the Ethernet hub 3 mounted on the first mounting plate 12.

[0052] In related technologies, the installation method of the new Ethernet hub has changed from screw fixing to movement via slider D and guide rail. However, due to the limited space on the mounting plate of the reactor protection system, it is impossible to install the guide rail.

[0053] In one embodiment, please refer to Figure 4 and Figure 5The reactor protection system includes fasteners. A conversion plate 2 has a first positioning hole 2c located on the side of a second mounting hole 2a away from its edge along a second direction. Exemplarily, the first positioning hole 2c is located between two second mounting holes 2a, specifically at the center of the conversion plate 2, allowing for clearance when fasteners are installed in the first mounting holes 12b1 and 2a. An Ethernet hub 3 has second positioning holes 3a formed therein. At least a portion of the fastener passes through the first positioning hole 2c and the second positioning hole 3a to secure the Ethernet hub 3 and the conversion plate 2, wherein the second direction is perpendicular to the thickness direction of the conversion plate 2. For example, when installing the Ethernet hub 3, the slider D can be removed first. Using the existing mounting holes for fixing the slider D, i.e., the second positioning hole 3a, and the fixing component, the fixing component can be inserted into the first positioning hole 2c and the second positioning hole 3a to complete the connection and fixation of the Ethernet hub 3 and the conversion board 2. In this way, on the one hand, by using the existing second positioning hole 3a and the fixing component of the Ethernet hub 3, the layout of the Ethernet hub 3 does not need to be redesigned, saving time and effort; on the other hand, by using the existing second positioning hole 3a and the fixing component, the fixing component can directly cooperate with the second positioning hole 3a after passing through the first positioning hole 2c, which is convenient, efficient, and easy to install.

[0054] For example, in one embodiment, the fastener can be a screw, and threads can be formed in the first positioning hole 2c and the second positioning hole 3a, and the fastener is threadedly engaged with the first positioning hole 2c and the second positioning hole 3a.

[0055] As an example, in one embodiment, please refer to Figure 4 and Figure 5 The system has two first positioning holes 2c, two second positioning holes 3a, and two fasteners. The two first positioning holes 2c are spaced apart along the second direction, and each fastener passes through the corresponding first positioning hole 2c and second positioning hole 3a. This further improves the connection strength between the conversion board 2 and the Ethernet hub 3, resulting in good operational stability.

[0056] In one embodiment, please refer to Figure 5The portion of the conversion plate 2 near the side of the first mounting plate 12 is recessed to form a groove 2d, which surrounds the outer periphery of the first positioning hole 2c. The fastener includes a head and a connecting portion. The head is connected to the connecting portion, which passes through the first positioning hole 2c and the second positioning hole 3a. The head is located in the groove 2d, and the surface of the head away from the connecting portion is not higher than the surface of the conversion plate 2 near the first mounting plate 12. That is, the surface of the head away from the connecting portion is coplanar with the surface of the conversion plate 2 near the first mounting plate 12, or the surface of the head away from the connecting portion is lower than the surface of the conversion plate 2 near the first mounting plate 12. In this way, after the fastener passes through the first positioning hole 2c and the second positioning hole 3a, the surface of its head away from the connecting portion will not protrude from the surface of the conversion plate 2 near the first mounting plate 12, allowing the conversion plate 2 and the first mounting plate 12 to fit completely. This not only avoids damage to the first mounting plate 12 caused by the head protruding, thus improving the service life of the first mounting plate 12, but also improves the connection stability between the conversion plate 2 and the first mounting plate 12.

[0057] In one embodiment, please refer to Figure 3 The projection of the Ethernet hub 3 onto the first mounting plate 12 is located within the original mounting area 12b. That is, the length and width dimensions of the Ethernet hub 3 are each less than or equal to the length and width dimensions of the original mounting area 12b. This reduces the area occupied by the Ethernet hub 3, providing space for subsequent cabling and wiring, resulting in high space utilization. The first mounting hole 12b1 is located on the outer periphery of the projection of the Ethernet hub 3 onto the first mounting plate 12. This facilitates the installation of fasteners.

[0058] In one embodiment, please refer to Figure 3 The reactor protection system includes wires 4 and electrical components 5, which are disposed around the periphery of the original mounting area 12b. For example, the shape of the first mounting plate 12 is not limited; for instance, the first mounting plate 12 can be rectangular, with a length of 470 mm and a width of 170 mm. The electrical components 5 can be disposed on the left side of the original mounting area 12b, and the wires 4 can be disposed on the upper and lower sides of the original mounting area 12b. This provides high integration and facilitates connection of the wires 4 to the Ethernet hub 3.

[0059] In one embodiment, please refer to Figure 3 The conductor 4 includes a signal cable 41 and a power cable 42. The electrical component 5 includes a power module 51, a communication module 52, and a power terminal 53. The power module 51 is located at the lower left of the first mounting plate 12, the communication module is located to the right of the power module 51, the power terminal 53 is located to the right of the communication module, the signal cable 41 is located above the first mounting plate 12, and the power cable 42 is located below the first mounting plate 12.

[0060] In one embodiment, please refer to Figure 2 and Figure 4 The Ethernet hub 3 has a power socket A formed on its side along the second direction for connecting to a power source. This reduces the length of the Ethernet hub 3 and its footprint. It should be noted that older external network hubs had all their fiber optic interfaces B, network cable interfaces C, and power socket A located on the front panel, spaced apart along the left-right direction, resulting in a length of 191mm and a width of 44mm. In this embodiment, the power socket A of the Ethernet hub 3 is located on one side along the second direction, for example, on one side along the left-right direction, reducing the size to 131mm in length and 41mm in width. This not only reduces the length of the Ethernet hub 3 along the second direction, but also increases the number of network cable interfaces C, for example, from four to six, to increase the number of device connections.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. All modifications, equivalent substitutions, improvements, etc., within the spirit and principles of this application are included within the scope of protection of this application.
