[0003] However, existing reactor protection cabinets are all designed in a fixed manner, which has the defect of insufficient vibration resistance when applied to mobile micro nuclear reactors. The control equipment in the reactor protection cabinet is easily damaged by vibration and impact when it is moved. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to address the above-mentioned shortcomings of the prior art by providing a vehicle-mounted nuclear reactor protection cabinet and a mobile nuclear reactor protection system, which can improve the seismic resistance of the vehicle-mounted nuclear reactor protection cabinet and prevent the control equipment in the vehicle-mounted nuclear reactor protection cabinet from being damaged by vibration and impact during movement.
[0005] In a first aspect, embodiments of the present invention provide a vehicle-mounted nuclear reactor protection cabinet, which includes a cabinet body and a vibration damping assembly. The cabinet body is disposed inside a vehicle compartment. The vibration damping assembly includes a first vibration damper and a second vibration damper; the first vibration damper is connected between the bottom plate of the cabinet body and the bottom plate of the vehicle compartment, for fixing the cabinet body to the bottom plate of the vehicle compartment and absorbing vibrations between the cabinet body and the bottom plate of the vehicle compartment; the second vibration damper is connected between the back plate of the cabinet body and the side plate of the vehicle compartment, for fixing the cabinet body to the side plate of the vehicle compartment and absorbing vibrations between the cabinet body and the side plate of the vehicle compartment.
[0006] In some embodiments, the vehicle-mounted nuclear reactor protection cabinet further includes control devices; the number of control devices is multiple. The cabinet body is internally divided into equipment compartments; each equipment compartment is provided with multiple drawers, and each drawer is correspondingly arranged with multiple control devices, with each control device located in a corresponding drawer.
[0007] In some embodiments, the cabinet body is further divided into an internal equipment wiring compartment and an external equipment wiring compartment, which are located on opposite sides of the equipment compartment. The multiple control devices are connected to each other by multiple first cables, which are arranged in the internal equipment wiring compartment.

[0010] In some embodiments, each of the first cables is connected to the control device via an aviation connector, and / or each of the second cables is connected to the control device via an aviation connector.
[0011] In some embodiments, both the first cable and the second cable are shielded cables.
[0012] In some embodiments, a heat sink is provided on the top of the cabinet body, which is used to exhaust hot air from inside the cabinet body.
[0013] Therefore, the vehicle-mounted nuclear reactor protection cabinet provided in this embodiment of the invention, by setting a first shock absorber and connecting it between the bottom plate of the cabinet body and the bottom plate of the vehicle, can fix the cabinet body to the bottom plate of the vehicle and absorb the vibration between the cabinet body and the bottom plate of the vehicle; by setting a second shock absorber and connecting it between the back plate of the cabinet body and the side plate of the vehicle, can fix the cabinet body to the side plate of the vehicle and absorb the vibration between the cabinet body and the side plate of the vehicle. Thus, the cabinet body is fixed in the vehicle through the first and second shock absorbers, and the vibration generated in any direction during the movement of the vehicle is absorbed, thereby reducing the vibration amplitude transmitted to the cabinet body, improving the seismic performance of the vehicle-mounted nuclear reactor protection cabinet, and preventing the control equipment in the vehicle-mounted nuclear reactor protection cabinet from being damaged by vibration and impact during movement.
[0014] Secondly, embodiments of the present invention also provide a mobile nuclear reactor protection system, which includes a vehicle compartment, the vehicle-mounted nuclear reactor protection cabinet mentioned in the first aspect, and a central control console.

All other embodiments obtained by those skilled in the art based on the embodiments provided by the present invention are within the scope of protection of the present invention.

[0022] As used herein, the term “and / or” includes any and all combinations of one or more related enumerated entries.

The embodiments of the invention described herein are not necessarily limited to the content of this document.
[0025] This document describes exemplary embodiments with reference to cross-sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the thickness of layers and the area of regions are enlarged for clarity. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the areas of the device, nor are they intended to limit the scope of the exemplary embodiments.
[0026] Example 1: like Figure 1As shown, this embodiment of the invention provides a vehicle-mounted nuclear reactor protection cabinet, which is applied in a mobile micro nuclear reactor for controlling the mobile micro nuclear reactor.
[0027] like Figure 1 and Figure 2 As shown, the vehicle-mounted nuclear reactor protection cabinet includes a cabinet body 1 and a vibration damping assembly. The cabinet body 1 is installed inside the vehicle compartment 2. The vibration damping assembly includes a first vibration damper 3 and a second vibration damper 4; the first vibration damper 3 is connected between the bottom plate of the cabinet body 1 and the bottom plate of the vehicle compartment 2, used to fix the cabinet body 1 to the bottom plate of the vehicle compartment 2 and absorb vibrations between the cabinet body 1 and the bottom plate of the vehicle compartment 2; the second vibration damper 4 is connected between the back plate of the cabinet body 1 and the side plate of the vehicle compartment 2, used to fix the cabinet body 1 to the side plate of the vehicle compartment 2 and absorb vibrations between the cabinet body 1 and the side plate of the vehicle compartment 2.
[0028] like Figure 3 and Figure 4 As shown, the cabinet body 1 can be made of metal, such as stainless steel, which gives it the advantages of impact resistance and corrosion resistance. The cabinet body 1 has an internal storage space for placing various devices (such as control equipment 5). The cabinet body 1 is equipped with an openable cabinet door.
[0029] For example, the dimensions of the rack body 1 can be set according to actual needs. For example, the dimensions of the rack body 1 can be 800mm×800mm×1800mm.
[0030] For example, the structures of the first damping member 3 and the second damping member 4 may be the same or different. In this embodiment, the first damping member 3 and the second damping member 4 are the same as an example for explanation.
[0031] Combination Figure 2 and Figure 4 There are four first shock absorbers 3, which are respectively installed at the four corners of the bottom plate of the cabinet body 1 to fix the bottom plate of the cabinet body 1; there are two second shock absorbers 4, which are sequentially installed at the top of the side plate of the cabinet body 1 in the horizontal direction to fix the side plate of the cabinet body 1.
[0032] With the above settings, the bottom and sides of the cabinet body 1 can be fixed to the carriage 2, so as to fix the cabinet body 1 inside the carriage 2, thereby maintaining the stability of the cabinet body 1 in the carriage 2 when the carriage 2 moves the cabinet body 1.
[0033] like Figure 5 and Figure 6As shown, the first shock absorber 3 can be a wire rope shock absorber. The wire rope shock absorber has the characteristics of large damping, low natural frequency, and buffering energy absorption, which can better absorb the vibration between the cabinet body 1 and the carriage 2.
[0034] For example, the first damping component 3 and the second damping component 4 can specifically adopt ALJ-81661 anti-symmetric (compressed) wire rope dampers. These wire rope dampers use 304 stainless steel plates and 304 stainless steel wire ropes, and have the characteristics of high damping, low natural frequency, and buffering energy absorption, making them suitable for vehicle use. In this case, the first damping component 3 supports the cabinet body 1 through compression support.
[0035] With the above settings, when vibration occurs in any direction during the movement of the carriage 2, the first damping component 3 and the second damping component 4 can absorb the vibration in any direction, thereby reducing the vibration amplitude transmitted to the cabinet body 1, improving the seismic performance of the vehicle-mounted nuclear reactor protection cabinet, and preventing the control equipment in the vehicle-mounted nuclear reactor protection cabinet from being damaged by vibration impact during movement.
[0036] Therefore, the vehicle-mounted nuclear reactor protection cabinet provided in this embodiment of the invention, by setting a first shock absorber 3 and connecting the first shock absorber 3 between the bottom plate of the cabinet body 1 and the bottom plate of the vehicle compartment 2, can fix the cabinet body 1 to the bottom plate of the vehicle compartment 2 and absorb the vibration between the cabinet body 1 and the bottom plate of the vehicle compartment 2. By setting a second shock absorber 4 and connecting the second shock absorber 4 between the back plate of the cabinet body 1 and the side plate of the vehicle compartment 2, can fix the cabinet body 1 to the side plate of the vehicle compartment 2 and absorb the vibration between the cabinet body 1 and the side plate of the vehicle compartment 2. Thus, the cabinet body 1 is fixed in the vehicle compartment 2 by the first shock absorber 3 and the second shock absorber 4, and the vibration generated in any direction during the movement of the vehicle compartment 2 is absorbed, thereby reducing the vibration amplitude transmitted to the cabinet body 1, improving the seismic performance of the vehicle-mounted nuclear reactor protection cabinet, and preventing the control equipment in the vehicle-mounted nuclear reactor protection cabinet from being damaged by vibration impact during movement.
[0037] In some embodiments, the vehicle-mounted nuclear reactor protection cabinet further includes control devices 5; the number of control devices 5 is multiple. The cabinet body 1 is internally divided into equipment rooms; multiple drawers are provided in the equipment rooms, and multiple drawers are correspondingly arranged with multiple control devices 5, with each control device 5 located in a corresponding drawer.
[0038] For example, the cabinet body 1 adopts a three-sided door design, with one front door and two side doors; the front door is a hinged door, and the left and right side doors are fixed with detachable screws for easy daily inspection and maintenance. The left side door is used to insert drawers, and the right side door is used to connect cables.
[0039] For example, the drawer is made of aluminum alloy, which can effectively shield the device to isolate and attenuate radiation interference, so that the control device 5 inside the drawer is not affected by the external electromagnetic field, and at the same time does not affect other devices outside the drawer.
[0040] For example, such as Figure 4 As shown, in this embodiment, there are six control devices 5 and six drawers, arranged sequentially from top to bottom in the equipment room. Each drawer has a crossbeam above it and a base support below it. The back panel of each drawer has a positioning pin to ensure its stability and quick opening and closing. The front panel of each drawer has screw locks to secure it to the internal frame of the cabinet body 1 after closing, preventing it from sliding out due to vibration.
[0041] For example, the six control devices 5 are functionally divided into a protection control unit, an output signal processing unit, and an environmental management unit. The protection control unit includes three control devices 5, namely a first protection control box, a second protection control box, and a third protection control box; the output signal processing unit includes two control devices 5, namely a first output signal processing box and a second output signal processing box. The environmental management unit includes one control device 5, which is an environmental management box.
[0042] For example, in this embodiment, combined with Figure 4 The six control devices 5, from top to bottom, are: the first output signal processing box, the second output signal processing box, the first protection control box, the second protection control box, the third protection control box, and the environmental management box.
[0043] Combination Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10 Taking the structure of the protection control box as an example, the protection control box contains multiple control components (this embodiment does not limit the specific internal structure of the protection control box). Multiple switches and indicator lights are installed on the front panel of the protection control box, allowing operators to visually observe its operating status after it is installed in the drawer. Multiple wiring holes are provided on both the left and right sides of the protection control box for easy wiring when the side doors of the cabinet body 1 are open. The wiring terminals of the protection control box are designed with a left-right distribution; internal system terminals are uniformly designed on the left side of the protection control box, while external terminals are designed on the right side. The terminal design of other control devices 5 is the same as that of the protection control box.
[0044] With the above configuration, multiple control devices 5 can be installed in the vehicle-mounted nuclear reactor protection cabinet at the same time, which improves the integration and modularity of the vehicle-mounted nuclear reactor protection cabinet, helps to reduce the size of the cabinet body 1, and makes the multiple control devices 5 independent of each other, avoiding electromagnetic interference and common cause failure between the control devices 5.
[0045] In some embodiments, such as Figure 4 As shown, the cabinet body 1 is further divided into an internal equipment wiring compartment and an external equipment wiring compartment, which are located on opposite sides of the equipment room. Figure 11 As shown, multiple control devices 5 are connected to each other via multiple first cables 6, which are installed in the wiring room of the equipment inside the cabinet; multiple control devices 5 are connected to equipment outside the cabinet via multiple second cables 7, which are installed in the wiring room of the equipment outside the cabinet.
[0046] For example, Figure 4 In the middle, the equipment room is located in the central area of the cabinet body 1, and the internal equipment wiring room and the external equipment wiring room are located on the left and right sides of the equipment room, respectively.
[0047] Figure 11 This is a left-side view of the vehicle-mounted nuclear reactor protection cabinet. Multiple first cables 6 are distributed in the equipment wiring compartment on the left side of the cabinet body 1. The first cables 6 are connecting cables between control devices 5, with short travel (length). The first cables 6 are mainly divided into analog cables between drawer cabinets, switch cables between drawer cabinets, and cables from the protection system to the output box.
[0048] Figure 12 This is a right-side view of the vehicle-mounted nuclear reactor protection cabinet. Multiple second cables 7 are distributed in the external equipment wiring compartment on the right side of the cabinet body 1. The second cables 7 are mainly divided into external input analog signal cables, external input digital signal cables, external power supply cables, external output signal cables, and communication optical fibers.
[0049] The above settings allow cables to be categorized by their origin, enabling cables transmitting different signals to be distributed across different areas, thus facilitating quick identification of the corresponding cables.
[0050] In some embodiments, such as Figure 11 As shown, the wiring room of the equipment inside the cabinet is equipped with multiple isolated cabinet cable trays 8, and multiple first cables 6 are respectively installed in different cabinet cable trays 8 according to their connection relationship or destination.
[0051] For example, Figure 11In the cabinet, there are five cable trays 8 in the equipment wiring compartment. Two cable trays 8 are located at the rear of the equipment wiring compartment, one cable tray 8 is located in the middle of the equipment wiring compartment, and two cable trays 8 are located at the front of the equipment wiring compartment.
[0052] For example, the cable tray 8 inside the cabinet adopts a layered approach, with a width of 40mm and a height of 30mm, 60mm or 90mm, etc.
[0053] like Figure 11 As shown, the two internal cable trays 8 at the rear of the equipment wiring compartment are used to accommodate the first cable 6 between any two of the first protection control box, the second protection control box, and the third protection control box. One internal cable tray 8 in the middle of the equipment wiring compartment is used to accommodate the first cable 6 connecting to the environmental box cable tray. The two internal cable trays 8 at the front of the equipment wiring compartment are used to accommodate the first cable 6 connecting to the first output signal processing box and the second output signal processing box, respectively.
[0054] For example, the minimum spacing between the first cables 6 in different cabinet cable trays 8 is greater than or equal to 2.5 cm.
[0055] The above settings can reduce electromagnetic interference between the multiple first cables 6 connecting the various control devices 5.
[0056] In some embodiments, such as Figure 12 As shown, the wiring room for external equipment is equipped with multiple isolated external cable trays 9, and multiple second cables 7 are installed in different external cable trays 9 according to their connection relationship.
[0057] For example, the external cable tray 9 adopts a layered approach, with a width of 40mm and a height of 30mm, 60mm, or 90mm, etc.
[0058] like Figure 12 As shown, six external cable trays 9 are provided at the rear of the external equipment wiring compartment. The six external cable trays 9 are used to accommodate the second cables 7 that connect the first output signal processing box, the second output signal processing box, the first protection control box, the second protection control box, the third protection control box, and the environmental management box, respectively.
[0059] For example, the minimum spacing between the second cables 7 in different external cable trays 9 is greater than or equal to 2.5 cm.
[0060] The above settings can reduce electromagnetic interference between the multiple second cables 7 connecting the various control devices 5.
[0061] In some embodiments, each first cable 6 is connected to the control device 5 via an aviation connector. Each second cable 7 is connected to the control device 5 via an aviation connector.
[0062] For example, such as Figure 13 As shown, the aforementioned aviation connectors can all be Y50 series connectors.
[0063] For example, the aviation connectors at both ends of the first cable 6 and the second cable 7 can be engraved with laser markings (plug markings), and the cable name markings are sleeved in the middle of the first cable 6 and the second cable 7.
[0064] With the above settings, the first cable 6 and the second cable 7 can be quickly plugged in and unplugged.
[0065] In some embodiments, both the first cable 6 and the second cable 7 are shielded cables.
[0066] For example, the first cable 6 and the second cable 7 are mainly analog signal cables and digital signal cables. The wire diameter and shielding method of the first cable 6 and the second cable 7 are selected according to different signal types.
[0067] Considering the presence of other electrical equipment and electromagnetic interference sources inside the vehicle, the switch signal cables adopt a whole copper mesh shielding design, while the analog signal cables adopt a twisted pair individual shielding design.
[0068] Considering the attenuation of analog signals by the cables, low-impedance cables with a wire diameter of 0.2 square millimeters are used for analog signal cables, cables with a wire diameter of 0.15 square millimeters are used for switch signal cables, and cables with a wire diameter of 0.2 square millimeters are used for power supply cables.
[0069] The above settings can prevent interference when the signal is transmitted on the first cable 6 and the second cable 7.
[0070] In some embodiments, such as Figure 12 As shown, a heat sink 10 is installed on the top of the cabinet body 1, which is used to exhaust hot air from inside the cabinet body 1.
[0071] For example, heat sinks 10 are provided on both sides of the top of the cabinet body 1. The heat sink 10 can be a cooling fan, and the airflow direction is bottom in and top out. When the PLC in the environmental protection box detects that the internal temperature of the cabinet body 1 is too high (e.g., exceeding 50°C) through the temperature sensor, the PLC in the environmental protection box controls the cooling fan to start. After the internal temperature of the cabinet body 1 drops (e.g., drops to 25°C), the PLC in the environmental protection box controls the fan to turn off.
[0072] The above settings can prevent the internal temperature of the cabinet body 1 from becoming too high and affecting the normal operation of the control equipment 5.
[0073] In some examples, a main grounding wire is installed inside carriage 2. A protective grounding busbar is installed inside the cabinet body 1, distributed across the entire outer shell of cabinet body 1, and ultimately connected to the main grounding wire. One point on each drawer is connected to the main grounding wire. The grounding terminal of each control device 5 is connected to the main grounding wire.
[0074] Example 2: like Figure 1 As shown, this embodiment of the invention also provides a mobile nuclear reactor protection system. The mobile nuclear reactor protection system includes a vehicle compartment 2, a vehicle-mounted nuclear reactor protection cabinet as described in Embodiment 1, and a central control console 11. The central control console 11 is located inside the vehicle compartment 2 and is connected to the control equipment 5 via a second cable 7.
[0075] like Figure 14 , Figure 15 and Figure 16 As shown, the center console 11 features an integrated design, measuring 600×890×1200 (length×width×height). It employs a front and rear double-door design; the rear door houses the host computer and incoming cables, while the front door houses other components. The center console 11's outer shell is made of stainless steel, offering impact resistance and corrosion resistance.
[0076] For example, the center console 11 is equipped with multiple wheels at its bottom to facilitate its movement. The wheels are equipped with locking devices (brakes) to maintain the position of the center console 11.
[0077] For example, staff can manually issue control commands to the control device 5 of the vehicle-mounted nuclear reactor protection cabinet through the central control console 11, so as to control the mobile micro nuclear reactor through the control device 5 (for example, to quickly shut down the mobile micro nuclear reactor when a malfunction occurs, so as to avoid an accident).
[0078] The above settings enable the mobile nuclear reactor protection system to move, preventing the control equipment in the vehicle-mounted nuclear reactor protection cabinet from being damaged by vibration and impact during movement.
[0079] In some embodiments, such as Figure 1 As shown, the multiple second cables 7 include a first in-vehicle cable 12 and a second in-vehicle cable 13. The central control console 11 is connected to the control equipment 5 via the first in-vehicle cable 12. A cable connection conversion board 14 is embedded in the side panel of the carriage 2. External signals are connected to the external end of the cable connection conversion board 14 via external cables. The control equipment 5 in the on-board nuclear reactor protection cabinet is connected to the internal end of the cable connection conversion board 14 via the second in-vehicle cable 13.
[0080] For example, the cable connection conversion board 14 has multiple first plugs on its in-vehicle end and multiple second plugs on its out-of-vehicle end. The multiple first plugs and multiple second plugs are correspondingly arranged and connected. The out-of-vehicle cable is connected to the second plug and then connected to the second in-vehicle cable 13 through the corresponding first plug, thus realizing the connection between the out-of-vehicle cable and the control device 5.
[0081] With the above settings, the external cable can be connected to the control device 5 without extending into the carriage 2, thus facilitating the connection between the external cable and the control device 5 inside the carriage 2.
[0082] In some examples, mobile nuclear reactor protection systems also include power supplies.
[0083] For example, this power supply uses a 150W AC-to-DC converter, suitable for harsh environments with high humidity, high dust, oiliness, and high vibration. The power supply features an aluminum casing, internal thermally conductive silicone filling, and active PFC functionality, achieving a conversion efficiency of 94%. Electromagnetic compatibility emissions comply with BS EN / EN55032 (CISPR32) Class B, BS EN / EN61000-3-2,-3, EAC TP TC 020. The power supply's electromagnetic compatibility immunity complies with BS EN / EN61000-4-2,3,4,5,6,8,11, BS EN / EN55035, Light Industry Standard (Surge 6KV), EAC TP TC 020.
[0084] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
