Description

Technical Field

[0001] This utility model relates to the field of nuclear power plant rod positioning systems, and in particular to a rod positioning system test cabinet. Background Technology

[0002] The control rod positioning system in a nuclear power plant is primarily used to monitor and control the positions of control rods in the reactor to ensure safe reactor operation and stable power output regulation. The system includes key components such as a switchgear enclosure, control rod mounting enclosure, KVM switch, industrial computer, transformer, input power supply assembly, 15VDC power supply and PLC assembly, DAQ assembly, and PDU. The cabinets used in the control rod positioning system have seismic resistance requirements and are typically constructed by welding together thick steel plates (e.g., 3mm or 5mm thick). They consist of an interconnected cuboid cabinet frame and six panels covering the frame. The cabinet frame includes main columns, main crossbeams, and main longitudinal beams. All components are directly fixed to the side panels to further improve their stability. However, this structural design makes component assembly and disassembly difficult, and the heat generated at the bottom of the components is dissipated through air, while the large area covered by the panels results in poor heat dissipation.

[0003] In existing technologies, the test cabinet for testing a rod-mount system is the same as the cabinet used in actual operation. However, during testing, the cabinet does not need to meet the seismic resistance requirements of actual use. Important components, especially the chassis, require frequent disassembly and reassembly, and good heat dissipation is essential. Using the aforementioned cabinet would result in inflexible installation, operation, debugging, and maintenance, poor heat dissipation, and an excessively long testing process with numerous potential failures. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing bar position system cabinet, which makes the testing process inflexible and the heat dissipation effect poor, and to provide a bar position system test cabinet.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A test cabinet for a bar positioning system has an inner cavity for accommodating components of the bar positioning system, and includes a cabinet frame.

[0007] The front of the test cabinet for the rod position system has an opening that connects to the inner cavity.

[0008] The test cabinet for the rod position system also includes a first column and a support component;

[0009] The first column is movably connected to the left and right sides of the cabinet frame;

[0010] The support is located between the first column and the opening, and both sides of the support are fixed to the cabinet frame and the first column, respectively.

[0011] The support member is used to support the heat dissipation part of the component. The support member is made of metal, and the size of the support member matches the size of the heat dissipation part of the component.

[0012] In this technical solution, the test cabinet for the rod-position system features an opening at the front connecting to the internal cavity, facilitating the assembly and disassembly of components within. A support component, fixed to the cabinet frame and the first upright, provides stable support, and its proximity to the opening allows for direct contact and operation of the supported components by the tester. The support component, made of a high thermal conductivity metal, supports the heat dissipation section of the components, and its dimensions are matched to significantly improve heat dissipation (if the heat dissipation section is significantly larger than the support component, the heat conduction of the support component will be significantly less than the heat dissipation of the heat dissipation section, resulting in most heat still needing to be dissipated through the air, limiting the improvement in heat dissipation efficiency; if the heat dissipation section is significantly smaller than the support component, the support component conducts heat a long distance from the heat dissipation section to the first upright and cabinet frame, leaving a large amount of heat inside the test cabinet, causing internal temperature rise). Simultaneously, the opening structure, combined with the internal ventilation design, further optimizes the overall heat dissipation efficiency. The support components can be flexibly added, removed, or adjusted, facilitating the rational layout of various components within the cavity according to actual needs, and also enabling the individual assembly and disassembly of specific components. This structural design enhances the operational convenience and heat dissipation of the test cabinet for the rod-position system, while also allowing for flexible layout to adapt to the testing requirements of the rod-position system.

[0013] Preferably, the first column is a rod parallel to the main column of the cabinet frame, and both the upper and lower ends of the first column can be detachably connected to the main longitudinal beam of the cabinet frame.

[0014] In this technical solution, the above-mentioned configuration improves the overall structural strength and stability of the cabinet. Multiple equally sized support components can be distributed on the first upright, simplifying the installation process, facilitating the manufacturing of the support components, and reducing the overall cost of the test cabinet for this bar-position system.

[0015] Preferably, the test cabinet for the bar positioning system further includes reinforcing longitudinal beams, which are arranged parallel to the main longitudinal beams and connected at both ends to the main uprights of the cabinet frame;

[0016] When the first column is connected to the main longitudinal beam, the reinforcing longitudinal beam abuts against the first column.

[0017] In this technical solution, the above-mentioned settings further enhance the structural strength of the test cabinet for the positioning system. At the same time, the longitudinal beams are strengthened to provide limiting protection for the side of the first column, preventing damage to other side structures of the positioning system test cabinet or to the side maintainers in the event of structural damage to the first column.

[0018] Preferably, at least one of the reinforcing longitudinal beams is located above the support member.

[0019] In this technical solution, the above-mentioned settings can be used to further limit the components supported by the supporting parts, thereby preventing the components from impacting the side of the test cabinet of the rod position system and causing damage.

[0020] Preferably, the test cabinet for the rod-position system further includes a second column and connector mounting components;

[0021] The second column and the connector mounting piece are both located at the front of the cabinet frame;

[0022] One end of the connector mounting component is connected to the second column, and the other end is connected to the main column of the cabinet frame.

[0023] In this technical solution, the connector is installed at the front of the cabinet frame through the above-described configuration, facilitating multiple insertion and removal operations during testing. The second upright provides support for the connector mounting components, preventing loosening or displacement caused by insertion and removal operations.

[0024] Preferably, the second column is a rod parallel to the main column, and both the upper and lower ends of the second column can be detachably connected to the main crossbeam of the cabinet frame.

[0025] In this technical solution, the above-mentioned settings further enhance the structural strength of the test cabinet for the bar positioning system.

[0026] Preferably, the test cabinet for the rod position system further includes a double-door structure, which is connected to the rear outer side of the cabinet frame.

[0027] In this technical solution, the above-mentioned configuration creates a large ventilation opening when the double-door structure is opened, which facilitates convection with the front opening of the test cabinet of the rod position system, further improving the heat dissipation effect.

[0028] Preferably, the test cabinet for the rod position system further includes a side protection component, which is detachably covered on the outer side of the cabinet frame.

[0029] In this technical solution, the above-mentioned settings facilitate the tester's observation and inspection of the status of the components in the cavity, improving the efficiency of system maintenance and monitoring; furthermore, when maintenance or inspection is not required, the side protective components can protect the components from damage caused by dust, accidental collisions, or other external factors.

[0030] Preferably, the test cabinet for the bar positioning system further includes multiple casters, which are symmetrically connected to the bottom of the cabinet frame.

[0031] In this technical solution, the above-mentioned settings allow the tester to quickly adjust the position of the test cabinet for the bar positioning system, facilitating movement in multiple test scenarios and locations to meet flexible testing needs. The casters are symmetrically distributed at the bottom of the cabinet frame, maintaining the balance of the test cabinet for the bar positioning system while elevating the cabinet frame, allowing air to carry away heat from the bottom of the cabinet frame and further improving heat dissipation efficiency.

[0032] Preferably, the test cabinet of the rod position system is made of a thin plate with a thickness of less than or equal to 1.5 mm.

[0033] In this technical solution, the manufacturing cost is reduced by the above settings. While meeting the basic strength requirements of the test scenario, the weight of the test cabinet of the rod position system is low, which facilitates movement and installation in the test scenario.

[0034] The positive and progressive effects of this utility model are as follows:

[0035] By providing this test cabinet for the rod-position system, an opening at the front connects to the internal cavity, facilitating the installation and removal of components within. Support members, fixed to the cabinet frame and the first upright, provide stable support, and their proximity to the opening allows testers direct access to and operation of the supported components. The support members, made of a high thermal conductivity metal, support the heat dissipation parts of the components, and their dimensions are matched to significantly improve heat dissipation. Simultaneously, the opening structure, combined with the internal cavity's ventilation design, further optimizes overall heat dissipation efficiency. The support members can be flexibly added, removed, or adjusted, allowing for a rational layout of the components within the cavity according to actual needs, and also facilitating the individual installation and removal of specific components. This structural design enhances the operational convenience and heat dissipation of the test cabinet for the rod-position system, while also allowing for flexible layout to adapt to the requirements of rod-position system testing.

[0065] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0066] like Figs. 1-3 As shown, this embodiment provides a test cabinet 2 for a rod position system, which has an inner cavity 21 for accommodating the components 1 of the rod position system, and includes a cabinet frame 22.

[0067] The front of the test cabinet 2 of the rod position system has an opening 23, which connects to the inner cavity 21 to facilitate the assembly and disassembly of the components 1 in the inner cavity 21.

[0068] The test cabinet 2 for the rod position system also includes a first column 241 and a support 243; the first column 241 is movably connected to the left and right sides of the cabinet frame 22; the support 243 is located between the first column 241 and the opening 23, and the two sides of the support 243 are respectively fixed to the cabinet frame 22 and the first column 241 to provide stable support, and the position of the support 243 is close to the opening 23, so that the tester can directly contact and operate the supported components 1.

[0069] The support 243 is used to support the heat dissipation part of component 1. The support 243 is made of metal, and its size matches the size of the heat dissipation part of component 1 (usually located at the bottom, not shown in the figure). Due to the high thermal conductivity of the metal material, the heat dissipation effect is significantly improved. If the size of the heat dissipation part is significantly larger than the size of the support 243, the heat conduction of the support 243 at the same time will be significantly less than the heat dissipation of the heat dissipation part, resulting in most of the heat still needing to be dissipated through the air, and the improvement in heat dissipation efficiency is limited. If the size of the heat dissipation part is significantly smaller than the size of the support 243, the support 243 conducts heat from the heat dissipation part to the first column 241 and the cabinet frame 22 over a long distance, and a large amount of heat still remains inside the test cabinet 2 of the rod position system, causing the internal cavity 21 to heat up.

[0070] Meanwhile, the structure of opening 23, combined with the ventilation design of the inner cavity 21, further optimizes the overall heat dissipation efficiency. The support component 243 can be flexibly added, removed, or adjusted, facilitating the rational layout of each component 1 within the inner cavity 21 according to actual needs, and also facilitating the individual assembly and disassembly of a specific component 1. The above structural design improves the operational convenience and heat dissipation effect of the test cabinet 2 for the bar position system, and allows for flexible layout to adapt to the testing requirements of the bar position system.

[0071] Specifically, in this embodiment, the components 1 shown in the accompanying drawings include: a switch cabinet 11, used to control the 220VAC power input of the test cabinet 2 of the bar position system, a power switch and a power indicator; a bar position cabinet 12, configured with a data I / O card, an encoding card and a backplane; a KVM 13 (Keyboard, Video, Mouse Switch) and an industrial computer 14 providing software operation and a human-machine interface for controlling interface display, bar position value display and parameter configuration, electric drive device control, etc.; a transformer 15 and an input power supply component 16, supplying power to the test cabinet 2 of the bar position system, the input power supply component 16 being equipped with a power supply and filter, a 24V power supply and a 6V power supply; a 15VDC power supply and a PLC component 17 (providing a 15V DC power supply device and a Programmable Logic Controller); a DAQ component 18 (Data Acquisition), used for signal acquisition, signal processing, etc.; and a PDU 19 (Power Distribution Unit).

[0072] Depending on the requirements for heat dissipation and assembly / disassembly, the following arrangement can be made: KVM 13, industrial computer 14, rack mount chassis 12, and transformer 15 should first be placed on the support 243, and then fixed to the two corresponding first columns 241 on the left and right sides with bolts; other components can be directly fixed to the two corresponding first columns 241 on the left and right sides with bolts. Of course, in other embodiments, the components may also include other necessary or optional parts, or remove parts that are unnecessary in the test, and the various parts can also be arranged in different ways as needed.

[0073] In this embodiment, the first column 241 is a rod parallel to the main column 221 of the cabinet frame 22, and both its upper and lower ends are detachably connected to the main longitudinal beam 223 of the cabinet frame 22 to improve the overall structural strength and stability of the cabinet. Multiple equally sized support members 243 can be distributed on the first column 241, simplifying the installation process, facilitating the manufacturing of the support members 243, and reducing the overall cost of the test cabinet 2 for this rod-position system.

[0074] In this embodiment, the bar positioning system test cabinet 2 also includes a reinforcing longitudinal beam 244. The reinforcing longitudinal beam 244 is arranged parallel to the main longitudinal beam 223, and both ends are connected to the main uprights 221 of the cabinet frame 22, further enhancing the structural strength of the bar positioning system test cabinet 2. When the first upright 241 is connected to the main longitudinal beam 223, the reinforcing longitudinal beam 244 abuts against the first upright 241. In this way, the reinforcing longitudinal beam 244 provides limiting protection for the side of the first upright 241, preventing damage to other side structures of the bar positioning system test cabinet or to the side maintainers in the event of structural damage to the first upright 241.

[0075] In this embodiment, at least one reinforcing longitudinal beam 244 is located above the support member 243 to further limit the component 1 supported by the support member 243, so as to prevent the component 1 from hitting the side of the test cabinet 2 of the rod position system and causing damage.

[0076] In this embodiment, the test cabinet 2 for the rod-mount system further includes a second column 242 and a connector mounting component 245; both the second column 242 and the connector mounting component 245 are located at the front of the cabinet frame 22; one end of the connector mounting component 245 is connected to the second column 242, and the other end is connected to the main column 221 of the cabinet frame 22. This arrangement mounts the connector at the front of the cabinet frame 22, facilitating multiple insertion and removal operations during testing. The second column 242 provides support for the connector mounting component 245, preventing loosening or displacement caused by insertion and removal operations.

[0077] In this embodiment, the second column 242 is a rod parallel to the main column 221, and both the upper and lower ends of the second column 242 can be detachably connected to the main crossbeam 222 of the cabinet frame 22, which further enhances the structural strength of the test cabinet 2 of the rod position system.

[0078] In this embodiment, the test cabinet 2 for the rod position system also includes a double-door structure 246, which is connected to the rear outer side of the cabinet frame 22. When the double-door structure 246 is opened, it forms a large ventilation opening, which is conducive to convection with the front opening 23 of the test cabinet 2 for the rod position system, further improving the heat dissipation effect.

[0079] In this embodiment, the test cabinet 2 of the rod position system also includes a side protection component (not shown in the figure). The side protection component is detachably covered on the outer side of the cabinet frame 22, which makes it convenient for the tester to observe and inspect the status of the components 1 in the inner cavity 21, thereby improving the efficiency of system maintenance and monitoring. Furthermore, when maintenance or inspection is not required, the side protection component can protect the components 1 and prevent damage to the components 1 caused by dust, accidental collisions or other external factors.

[0080] In this embodiment, the test cabinet 2 for the bar positioning system also includes multiple casters 25. The casters 25 are symmetrically connected to the bottom of the cabinet frame 22, allowing the tester to quickly adjust the position of the test cabinet 2 for easy movement in multiple test scenarios and test locations, meeting flexible testing needs. The casters 25 are symmetrically distributed at the bottom of the cabinet frame 22, maintaining the balance of the test cabinet 2 while suspending the cabinet frame 22, allowing air to carry away heat from the bottom of the cabinet frame 22, further improving heat dissipation efficiency.

[0081] In this embodiment, each of the eight vertices connecting the main column 221, main crossbeam 222, and main longitudinal beam 223 has a T-joint 224, which is fixed by bolts. The reinforcing longitudinal beam 244 is fixed to the main column 221 by bolts. The first column 241 is fixed to the large column 3 by bolts. The support member 243 is fixed to the first column 241 by bolts. The second column 242 is fixed to the main crossbeam 222 by bolts. The connector mounting member 245 is fixed to the first column 241 and the second column 242 by bolts. The casters 25 are fixed to the bottom of the cabinet frame 22 by bolts. The above arrangement facilitates the disassembly of each structure. Of course, in other embodiments, other structural solutions can be introduced to adapt to testing requirements.

[0082] In this embodiment, the test cabinet 2 of the rod position system is made of thin plate with a thickness of less than or equal to 1.5 mm, thereby reducing manufacturing costs. While meeting the basic strength requirements of the test scenario, the weight of the test cabinet 2 of the rod position system is low, which facilitates movement and installation in the test scenario.
