Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of nuclear reactor equipment, in particular to an integrated cable plug-in structure. BACKGROUND

[0002] During the refueling, maintenance or decommissioning operation of a nuclear reactor, there are a large number of electrical, signal and fluid connectors distributed in the reactor interior and the reactor top area, which provide power, control signals and medium transmission channels for key equipment such as the pressure vessel, in-vessel components and control rod drive mechanisms. Currently, the disassembly and assembly of these connectors are generally carried out in a single and discrete manner, i.e. relying on the operator to personally go to the radiation site and manually operate the dozens to hundreds of connectors scattered in various parts of the equipment one by one. This traditional operation mode has the following significant disadvantages, which seriously restricts the safety of nuclear power plants:

[0003] 1. High risk to personnel safety: The operator needs to be exposed to the radiation environment for a long time, even if equipped with protective equipment, it will inevitably accumulate radiation dose, which will have a potential impact on their health.

[0004] 2. Low operation efficiency: The process of disassembling and assembling a large number of connectors one by one is tedious and time-consuming, which directly prolongs the outage and repair cycle of the reactor, and has a direct impact on the operation efficiency of the power plant.

[0005] 3. Insufficient automation and remote control: Due to the scattered distribution and different specifications of the connectors, it is difficult to achieve unified and efficient automatic operation, which has become a key bottleneck restricting the development of "unmanned" maintenance technology.

[0006] Therefore, in order to completely reverse the above difficulties, it is urgent to develop a new installation structure that can realize the centralized management and overall collaborative operation of the connectors. SUMMARY

[0007] The technical problem to be solved by the present application is to overcome the low efficiency of disassembly and assembly of connectors during the refueling, maintenance or decommissioning operation of a nuclear reactor in the prior art, and to provide an integrated cable plug-in structure.

[0008] The present application solves the above technical problems by the following technical scheme:

[0009] The present application provides an integrated cable plug-in structure, which comprises a mounting disc and a main shaft, the mounting disc has opposite first and second faces, a plurality of connector holes are formed in the mounting disc, the connector holes are used for mounting male heads of cables and making the plug-in ends of the male heads of the cables protrude out of the second face to be matched with female heads arranged on a nuclear reactor equipment one by one.

[0010] The mounting disc is further provided with a mounting hole, and the main shaft is rotatably arranged in the mounting hole.

[0011] When the main shaft is rotated in the first direction, the mounting disc is driven to move towards the nuclear reactor device, so that the male connector is inserted into the female connector.

[0012] In the scheme, the discrete male connectors are integrated by the mounting disc, and the rotation of the main shaft synchronously drives the male connectors to accurately extend and be inserted into the female connector on the nuclear reactor device, so that the stable contact between the male connector and the female connector is maintained, the time for connecting or disconnecting the cable is greatly shortened, and the efficiency and reliability of the synchronous management of the multiple cables during the maintenance or assembly of the nuclear reactor device are improved.

[0013] Optionally, the main shaft is further arranged to drive the mounting disc to move away from the nuclear reactor device when the main shaft is rotated in a second direction, so that the male connector is disconnected from the female connector; and the second direction is opposite to the first direction.

[0014] In the scheme, the rotation of the main shaft in the direction opposite to the first direction realizes the separation of the male connector and the female connector, and manual removal of the cables one by one is not required, so that the cable management process during the maintenance or disassembly of the nuclear reactor device is simplified.

[0015] Optionally, the connecting part is an external thread arranged on the first end, and the nuclear reactor device is provided with a groove threadedly matched with the connecting part.

[0016] In the scheme, the main shaft and the nuclear reactor device are fixed by using the threaded connection mode, and the structure is simple, the connection is stable, and the threaded matching operation is simple.

[0017] Optionally, a key groove is arranged on the top of the main shaft, and the key groove is used in cooperation with a dismounting component for rotating the main shaft.

[0018] In the scheme, the key groove cooperates with the dismounting component to ensure that the force is accurately applied and the torque is stably transmitted during operation.

[0019] Optionally, the integrated cable connector structure further comprises a side plate and a top plate, the side plate is arranged on the first surface of the mounting disc and is circumferentially arranged around the main shaft to form a circumferentially closed space, and the plurality of connector holes are arranged on the mounting disc in the space formed by the side plate.

[0020] The top of the side plate is covered by the top plate, the top plate is provided with a through hole, and the second end of the main shaft away from the first end passes through the through hole.

[0021] The side plate is also provided with a cable outlet, which is used to allow multiple cables connected to the male cable to pass through.

[0022] In this design, the side panel, top panel, and mounting plate form a space for accommodating cables. The side panel and top panel can integrate and protect the cables housed in this space.

[0023] Optionally, the integrated cable connector structure further includes a bushing assembly, which includes a bushing body, one end of which is connected to the mounting plate and the other end of which is connected to the top plate, and the spindle is disposed within the bushing body.

[0024] In this solution, the bushing body provides stable axial guidance and radial support for the rotating spindle, preventing the cable from being pulled and damaged or disconnected from the male end when the spindle rotates, thus improving connection reliability.

[0025] Optionally, the bushing assembly further includes a bearing disposed within the bushing body, through which the main shaft passes;

[0026] And / or, a first limiting part is provided on the second end of the spindle, and a second limiting part is provided on the bushing assembly or the top plate to cooperate with the first limiting part. The second limiting part is used to limit the distance that the second end of the spindle moves toward the mounting plate.

[0027] And / or, a hoisting part is provided on the side of the top plate away from the mounting plate.

[0028] In this design, the bearing acts as the second limiting part. When the spindle rotates and the first limiting part at the second end of the spindle comes into contact with the bearing, the spindle cannot move downwards. This limits the downward movement of the spindle, thereby effectively controlling the displacement when the male and female connectors of the cable are plugged in, and preventing the male connector from being over-inserted and damaging the female connector due to excessive movement.

[0029] Optionally, the integrated cable plug structure further includes a positioning element, which is disposed on the second side of the mounting plate, and the length of the positioning element extending out of the second side is greater than the length of the plug end of the male cable protrusion extending out of the second side;

[0030] The positioning element is used to mate with the first positioning hole on the nuclear reactor equipment so that the plug end of the male cable is connected to the female cable on the nuclear reactor equipment one by one.

[0031] In this solution, the positioning component can be precisely aligned with the first positioning hole on the nuclear reactor equipment before the male cable connector, ensuring the accurate relative position of the entire mounting plate and the nuclear reactor equipment. This ensures that the plug ends of each male cable connector are strictly aligned with the corresponding female connector, avoiding misalignment or forced connection due to installation deviation.

[0032] Optionally, the positioning element includes a positioning pin and an elastic element. The mounting plate is provided with a second positioning hole. The positioning pin is installed in the second positioning hole. The elastic element is sleeved on the positioning pin, and one end of the elastic element is connected to the mounting plate and the other end is connected to the positioning pin.

[0033] In this design, when the mounting plate is connected to the nuclear reactor equipment, the elastic component can buffer the locating pin to avoid damage to the locating pin due to rigid contact.

[0034] Optionally, the locating pin is made of a flexible material;

[0035] And / or, the positioning pin includes an insertion section and a guide section, one end of the guide section is inserted into the second positioning hole, and the other end is connected to the insertion section, the elastic element is sleeved on the guide section, one end of the elastic element abuts against the mounting plate, and the other end abuts against the insertion section.

[0036] The positive and progressive effects of this invention are as follows:

[0037] In this application, discrete male cable connectors are integrated together by an installation panel. The rotation of the spindle synchronously drives each male cable connector to extend precisely and align with the female connector on the nuclear reactor equipment, maintaining stable contact between the two. This significantly shortens the time for cable connection or disconnection and improves the efficiency and reliability of multi-cable synchronous management during the maintenance or assembly of nuclear reactor equipment.

[0070] Please see Figures 1-4 This embodiment provides an integrated cable plug-in structure. Figure 1 This is a cross-sectional schematic diagram of an integrated cable plug-in structure provided in an embodiment of this application; Figure 2 This is a three-dimensional structural diagram of an integrated cable plug-in structure provided in the embodiments of this application; Figure 3 This is a front view of an integrated cable plug-in structure provided in an embodiment of this application; Figure 4 This is a three-dimensional structural diagram of an integrated cable connector structure provided in this application embodiment, from another perspective. The integrated cable connector structure includes a mounting plate 1 and a spindle 2. The mounting plate 1 has a first surface 11 and a second surface 12 facing each other. The mounting plate 1 has multiple insertion holes 13 for mounting male cable connectors 3, with the insertion end of the male cable connector 3 extending out of the second surface 12 to mate with female connectors installed on the nuclear reactor equipment. The mounting plate 1 also has mounting holes 14, within which the spindle 2 is rotatably mounted. The spindle 2 has a first end with a connecting portion 21 that is fixed to the nuclear reactor equipment. When the spindle 2 is configured to rotate in a first direction (e.g., clockwise), it moves the mounting plate 1 closer to the nuclear reactor equipment, allowing the male cable connector 3 to mate with the female connector. The cable includes electrical cables, signal cables, or fluid cables used in the nuclear reactor equipment. The insertion end of the male cable connector 3 can be fixed to the second surface 12 of the mounting plate 1 with a nut.

[0071] In this application, discrete male cable connectors 3 are integrated together by mounting plate 1. The rotation of spindle 2 synchronously drives each male cable connector 3 to extend precisely and align with the female connector on the nuclear reactor equipment, maintaining stable contact between the two. This significantly shortens the time for cable connection or disconnection and improves the efficiency and reliability of multi-cable synchronous management during the maintenance or assembly of nuclear reactor equipment.

[0072] In this embodiment, the spindle 2 is also configured to rotate in a second direction (e.g., counterclockwise) to move the mounting plate 1 away from the nuclear reactor equipment, thereby disconnecting the male cable connector 3 from the female cable connector; the second direction is the opposite of the first direction. By rotating the spindle 2 in the opposite direction to the first direction, the separation of the male cable connector 3 from the female cable connector is achieved, eliminating the need to manually unplug cables one by one and simplifying the cable management process during the maintenance or disassembly of nuclear reactor equipment.

[0073] Specifically, the connecting part 21 of the main shaft 2 has an external thread at its first end, and the nuclear reactor equipment has a groove that mates with the thread of the connecting part 21. A keyway 22 is provided on the top of the main shaft 2, which is used to mate with a disassembly / assembly component for rotating the main shaft 2. The threaded connection method secures the main shaft 2 to the nuclear reactor equipment, resulting in a simple structure, a stable connection, and easy operation. The keyway 22, in conjunction with the disassembly / assembly component, ensures precise force application and stable torque transmission during operation.

[0074] When it is necessary to connect the male connector 3 of the cable to the female connector on the nuclear reactor equipment so that the nuclear reactor equipment can work normally, the disassembly and assembly parts engage with the keyway 22 on the top of the spindle 2 and rotate the spindle 2 in the first direction. The spindle 2 drives the mounting plate 1 to move closer to the nuclear reactor equipment. The first end of the spindle 2 is inserted into the groove of the nuclear reactor equipment and connected to the nuclear reactor equipment through threads. At this time, the male connector 3 of the cable integrated on the mounting plate 1 engages with the female connector on the nuclear reactor equipment one by one.

[0075] When it is necessary to disconnect the male connector 3 of the cable from the female connector on the nuclear reactor equipment, the disassembly and assembly components rotate the spindle 2 in a second direction opposite to the first direction, so that the spindle 2 drives the mounting plate 1 to move away from the nuclear reactor equipment and disconnect the male connector 3 of the cable from the female connector.

[0076] In other embodiments, the end face of the connecting part 21 of the spindle 2 has a groove, and an internal thread is provided in the groove. The matching nuclear reaction equipment has an external thread protrusion, and the protrusion engages with the groove thread.

[0077] In this embodiment, the integrated cable connector structure further includes a side plate 4 and a top plate 5. The side plate 4 is mounted on the first surface 11 of the mounting plate 1 and forms a circumferentially enclosed space around the main shaft 2. Multiple connector holes are provided on the mounting plate 1 within the space formed by the side plate 4. The top of the side plate 4 is covered by the top plate 5, which has a through hole through which the second end 23 of the main shaft 2, away from the first end, passes. The side plate 4 also has a cable outlet 41 for multiple cables connected to the male cable connector 3 to pass through. The side plate 4, the top plate 5, and the mounting plate 1 form a space for accommodating cables. The side plate 4 and the top plate 5 can integrate and protect the cables accommodated in this space. The mounting plate 1, the side plate 4, and the top plate 5 can be made of materials capable of shielding electromagnetic fields to provide electromagnetic shielding.

[0078] Combination Figure 1 Continuing the explanation, in this embodiment, the integrated cable plug-in structure also includes a bushing assembly 6, which includes a bushing body 61. One end of the bushing body 61 is connected to the mounting plate 1, and the other end is connected to the top plate 5. The main shaft 2 is disposed inside the bushing body 61.

[0079] By setting the bushing body 61, a stable axial guide and radial support are provided for the rotating spindle 2, which avoids the spindle 2 pulling the cable when rotating, causing cable damage or disconnecting the cable from the male cable connector 3, thus improving the reliability of the connection.

[0080] Specifically, the bushing assembly 6 also includes a bearing 62, which is disposed inside the bushing body 61 and connected to the bushing body 61. The main shaft 2 passes through the bearing 62. There can be two bearings 62, which are respectively disposed at both ends of the main shaft 2.

[0081] In this embodiment, a first limiting part 231 is provided on the second end 23 of the spindle 2, and a second limiting part that cooperates with the first limiting part 231 is provided on the bushing assembly 6 or the top plate 5. The second limiting part is used to limit the distance that the second end 23 of the spindle 2 moves toward the mounting plate 1. In this embodiment, the bearing 62 serves as the second limiting part. When the spindle 2 rotates and the first limiting part 231 of the second end 23 of the spindle 2 abuts against the bearing 62, the spindle 2 cannot move downward. This can limit the distance that the spindle 2 moves downward, thereby effectively controlling the displacement of the male cable head 3 when it is plugged into the female cable head, and avoiding damage to the female cable head due to excessive insertion caused by excessive movement.

[0082] In some embodiments, the spindle 2 may also be configured to rotate only relative to the mounting plate 1 without axial movement. In this configuration, the connecting portion 21 at the first end of the spindle 2 is configured to extend beyond the second surface of the mounting plate 1 by a predetermined length, which matches the groove depth of the nuclear reactor equipment.

[0083] In this embodiment, the integrated cable plug-in structure also includes a positioning element 8, which is disposed on the second surface 12 of the mounting plate 1. The length of the positioning element 8 extending out of the second surface 12 is greater than the length of the plug end of the male cable 3 extending out of the second surface 12. The positioning element 8 is used to cooperate with the first positioning hole on the nuclear reactor equipment so that the plug end of the male cable 3 can be plugged into the female connector on the nuclear reactor equipment one by one.

[0084] The positioning component 8 can be precisely aligned with the first positioning hole on the nuclear reactor equipment before the male cable connector 3, ensuring that the relative position of the entire mounting plate 1 and the nuclear reactor equipment is accurate, thereby ensuring that the plug end of each male cable connector 3 is strictly aligned with the corresponding female connector, avoiding misalignment or forced connection due to installation deviation.

[0085] Combination Figures 2 to 4 Continuing the explanation, the positioning component 8 includes a positioning pin 81 and an elastic element 82. The mounting plate 1 has a second positioning hole 15, and the positioning pin 81 is installed within the second positioning hole 15. The elastic element 82 is sleeved on the positioning pin 81, with one end of the elastic element 82 connected to the mounting plate 1 and the other end connected to the positioning pin 81. The positioning pin 81 is made of a flexible material. In this design, when the mounting plate 1 docks with the nuclear reactor equipment, the elastic element 82 can buffer the positioning pin 81, preventing damage to the positioning pin 81 due to rigid contact.

[0086] Furthermore, the positioning pin 81 includes an insertion section 811 and a guide section 812. One end of the guide section 812 is inserted into the second positioning hole 15 and extends out of the first surface 11 of the mounting plate 1, while the other end is connected to the insertion section 811. An elastic element 82 is sleeved on the guide section 812, with one end of the elastic element 82 abutting against the mounting plate 1 and the other end abutting against the insertion section 811. The positioning pin 81 is fixed to the mounting plate 1 by a nut.

[0087] In this embodiment, a lifting section 7 is provided on the side of the top plate 5 away from the mounting plate 1. The lifting section 7 can serve as a force application point for automated equipment such as robotic arms to remotely operate this structure.

[0088] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
