Detailed Implementation

[0058] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0059] In one embodiment, Figure 1 This is a schematic diagram of a steam generator replacement auxiliary system provided in one embodiment. In this embodiment, the steam generator replacement auxiliary system includes: a data acquisition device 10, used to acquire stress data of the main pipeline 01 and send the stress data to a remote terminal 20; the remote terminal 20, used to determine the position movement information of the main pipeline 01 based on the stress data and send the position movement information to a position control device 30; and the position control device 30, used to move the position of the main pipeline 01 according to the position movement information, so as to align and install the main pipeline 01 with the steam generator to be replaced.

[0060] Main pipe 01 is a crucial component of the nuclear power plant's main loop, comprising a cold section and a hot section. The cold section connects the main pump to the pressure vessel, while the hot section connects the steam generator to the pressure vessel. Stress is a force exerted on both ends of the steam generator by the transition section (the pipe connecting the steam generator to the main pump) and the hot section of the main pipe. This stress occurs vertically during steam generator replacement and cutting, and the stress data is the magnitude of this force recorded by data acquisition device 10. The steam generator is one of the most critical pieces of equipment in the nuclear steam supply system. Its primary loop pressure boundary area accounts for approximately 80% of the total pressure boundary area of ​​the primary loop system. Its heat transfer tubes have thin walls and operate under harsh conditions, making it the weakest pressure boundary in the primary loop system.

[0061] The steam generator replacement auxiliary system in this embodiment includes a data acquisition device 10, a remote terminal 20, and a position control device 30. The data acquisition device 10 is mounted on top of the position control device 30. The remote terminal 20 receives stress data transmitted by the data acquisition device 10 via a signal transmission cable. The data acquisition device 10 acquires stress data of the main pipeline 01 on the position control device 30 and sends the stress data to the remote terminal 20. The remote terminal 20 receives the stress data acquired by the data acquisition device 10, analyzes and processes the stress data, and obtains the position movement information of the main pipeline 01. Then, the remote terminal 20 sends the position movement information to the position control device 30. After receiving the position movement information, the position control device 30 moves the main pipeline 01 according to the position movement information to align and install the main pipeline with the replacement steam generator.

[0062] The data acquisition device 10 can transmit stress data to the remote terminal 20 via signal transmission cables, 4G, or other methods. Similarly, the remote terminal 20 can transmit position movement information to the position control device 30 via signal transmission cables, 4G, or other methods. The transmission methods for stress data and position movement information in this embodiment are not limited to those described in the above embodiments and can be configured according to actual circumstances.

[0063] The aforementioned steam generator replacement auxiliary system includes a data acquisition device, a position control device, and a remote terminal. These devices can coordinate with each other to work together. The data acquisition device can collect stress data in a timely and efficient manner, and the remote terminal can analyze and process the collected stress data to obtain position adjustment information. The position control device can then adjust the position based on the transmitted position adjustment information, providing the necessary conditions for subsequent steps such as beveling, assembly, and welding. This greatly facilitates the precise formulation of effective implementation plans.

[0064] In one embodiment, such as Figure 1 As shown, the remote terminal 20 is used to determine the assembly method and the bevel size of the main pipeline based on stress data during the bevel assembly process, and to determine the position movement information based on the assembly method and the bevel size.

[0065] Among them, bevel alignment refers to a method in which, after the steam generator is replaced and cut, the main pipe 01 is adjusted to a suitable position, and the bevel of the main pipe 01 is matched with the bevel of the steam generator. A bevel is a shape designed to facilitate alignment. Position movement information refers to the information on the optimal movement position of the main pipe 01, which is the best position for bevel alignment.

[0066] During the beveling process, the remote terminal 20 receives stress data collected by the data acquisition device 10, and uses a first preset algorithm to determine the assembly method of the steam generator and the main pipeline 01 and the beveling size of the main pipeline 01 based on the stress data. It also determines the positional movement information of the main pipeline 01 based on the assembly method and beveling size. This embodiment does not limit the first preset algorithm.

[0067] In the above embodiments, since the determination of the assembly method of the main pipeline and the steam generator and the calculation of the bevel size are completed in the remote terminal, work efficiency can be improved, the construction period can be shortened, the measurement accuracy can be improved, and the radiation dose to personnel can be effectively reduced.

[0068] In one embodiment, such as Figure 1 As shown, the remote terminal 20 is also used to determine the welding start position based on stress data during the welding process, and to determine the position movement information based on the welding start position.

[0069] The welding start position refers to the location where the bevel of the main pipeline 01 is welded to the bevel of the replaced steam generator. The position movement information refers to the optimal movement position of the main pipeline 01, which is the best position for welding the steam generator to the main pipeline 01.

[0070] During the welding process, the remote terminal 20 determines the welding start position based on the stress data collected by the data acquisition device 10 using a second preset algorithm, and determines the position movement information of the main pipeline 01 based on the welding start position. This application embodiment does not limit the second preset algorithm.

[0071] Optionally, the remote terminal 20 can also determine the welding method based on stress data.

[0072] In the above embodiments, during the welding process, the remote terminal determines the welding start position based on stress data and determines the position movement information based on the welding start position. Because the remote terminal has developed a precise plan for the connection between the main pipeline bevel and the steam generator bevel by analyzing the stress data and calculating the position movement information of the main pipeline, the accuracy and stability of the entire welding process are guaranteed.

[0073] In one embodiment, such as Figure 2 As shown, the aforementioned position control device 30 includes a controller 301, a drive motor 302, and a displacement platform 303. The controller 301 is used to receive position movement information sent by the remote terminal 20 and send drive signals to the drive motor 302 according to the position movement information; the drive motor 302 is used to drive the displacement platform 303 to move according to the drive signals; the displacement platform 303 is used to carry the main pipeline 01 and move the main pipeline 01 during the position movement.

[0074] The controller 301 processes signals, transmitting the position of the main pipeline 01 on the displacement platform 303 back to the remote terminal 20, and transmitting the command signals from the remote terminal 20 to the drive motor 302. The drive motor 302 controls the displacement platform 303 to move according to the command signals from the controller 301, thereby adjusting the main pipeline 01 to a suitable position.

[0075] In the above embodiments, the controller, drive motor, and displacement platform work together as position control devices, enabling the remote terminal to move the position of the main pipeline. This overcomes the shortcomings of slow manual mechanical adjustment, improves work efficiency, and enhances the safety of the entire system.

[0076] In one embodiment, such as Figure 3 As shown, the position control device 30 also includes a support and fixing structure 304: the support and fixing structure 304 is used to support the displacement platform 303 and fix the main pipeline 01 on the displacement platform 303.

[0077] The 304 stainless steel supporting and fixing structure mainly serves to support and fix the structure.

[0078] In the above embodiments, the supporting and fixed structure can support and move the main pipeline, thereby ensuring the stable operation of the entire system.

[0079] In one embodiment, such as Figure 4 As shown, the aforementioned support and fixing structure 304 includes a first support structure 3041, a second support structure 3042, and a fixing structure 3043; the first support structure 3041 is used to support the displacement platform 303; the second support structure 3042 is disposed on the displacement platform 303 and is used to support the main pipeline 01; the fixing structure 3043 is disposed on the second support structure 200 and is used to fix the main pipeline 01 on the displacement platform 303.

[0080] The first support structure 3041 includes outriggers and a counterweight. The outriggers support the displacement platform 303 and are telescopic, with their length adjustable according to the position. The counterweight is fixed to the outriggers; since the main pipe 01 is heavy, the counterweight, combined with the outriggers, provides better support. The second support structure 3042 is adjustable in the X, Y, and Z directions, located above the displacement platform 303, and connected to the fixed structure 3043, where it is locked and cannot be moved. Furthermore, the fixed structure can be adjusted and fixed according to the dimensions of the main pipe 01 and is integral with the main pipe 01, making it immovable.

[0081] During the beveling process, the outriggers and counterweights support the displacement platform 303. The displacement platform 303 controls the displacement of the second support structure 3042 according to the position movement information given by the remote terminal 20. A fixing structure 3043 is installed on the second support structure 3042, which fixes the main pipeline 01 to the displacement platform 303.

[0082] Adaptively, during the welding process, the outriggers and counterweights support the displacement platform 303. The displacement platform 303 controls the displacement of the second support structure 3042 according to the position movement information given by the remote terminal 20. A fixing structure 3043 is installed on the second support structure 3042, which fixes the main pipe 01 to the optimal welding position.

[0083] In the above embodiments, the supporting and fixing structure includes a first supporting structure, a second supporting structure, and a fixing structure. The first supporting structure supports the displacement platform; the second supporting structure is disposed on the displacement platform and supports the main pipeline; the fixing structure is disposed on the second supporting structure and fixes the main pipeline to the displacement platform. The first supporting structure, the second supporting structure, and the fixing structure mutually restrict and cooperate with each other. The first supporting structure mainly supports the main pipeline, the second supporting structure mainly facilitates the movement of the main pipeline, and the fixing structure effectively fixes the main pipeline to the optimal position required at each stage.

[0084] Figure 5 This is a flowchart illustrating a steam generator replacement auxiliary method according to one embodiment. This embodiment describes the specific process of the steam generator replacement auxiliary method, taking its application to a remote terminal as an example. It may include the following steps:

[0085] S401: During the steam generator replacement process, acquire stress data of the main pipeline.

[0086] During the main pipeline cutting, beveling, and welding processes, the data acquisition device can acquire stress data in real time and transmit the stress data to a remote terminal via signal transmission cables. The remote terminal receives the stress data transmitted by the data acquisition device.

[0087] S402, determine the position movement information of the main pipeline based on stress data.

[0088] During the main pipeline cutting, beveling, and welding processes, the remote terminal uses a preset algorithm to analyze and calculate the collected stress data, thereby determining the positional movement information of the main pipeline.

[0089] S403, the position movement information is sent to the position control device, which is used to instruct the position control device to move the main pipeline to align and install the main pipeline with the replacement steam generator.

[0090] The remote terminal sends position movement information to the controller via a signal transmission cable. The controller then drives the drive motor, which in turn moves the second support structure on the displacement platform in the X, Y, and Z directions. This adjusts the position of the main pipeline, making it easier to align the bevel of the main pipeline with the bevel of the steam generator during the bevel assembly process. Adaptively, this allows the main pipeline to be adjusted to the optimal welding position with the replaced steam generator during the welding process.

[0091] In the above embodiments, during the steam generator replacement process, stress data of the main pipeline is acquired, and the position movement information of the main pipeline is determined based on the stress data. This position movement information is then sent to the position control device, which instructs the device to move the main pipeline to align it with the replacement steam generator for installation. This process involves remote real-time monitoring of stress changes in the main pipeline via a terminal, making the operation convenient and quick, effectively avoiding radiation exposure to personnel, and laying the foundation for developing accurate beveling and welding plans.

[0092] In one embodiment, such as Figure 6 As shown, determining the positional movement information of the main pipeline based on stress data can include:

[0093] S501, during the beveling process of replacing the steam generator, the assembly method and the beveling size of the main pipeline are determined based on stress data.

[0095] S502, determine the position movement information based on the assembly method and bevel size.

[0096] The remote terminal determines the position movement information of the main pipeline using the first preset algorithm based on the pairing method and bevel size.

[0097] In the above embodiments, during the beveling process of replacing the steam generator, the beveling method and the beveling size of the main pipeline are determined based on stress data, and the positional movement information is determined based on the beveling method and beveling size. Real-time monitoring of the stress changes in the main pipeline during the beveling process via a remote terminal facilitates the development of precise beveling plans and calculation of beveling sizes, enabling the main pipeline to be adjusted to a suitable beveling position, thus improving work efficiency and safety.

[0098] In one embodiment, such as Figure 7 As shown, determining the positional movement information of the main pipeline based on stress data can include:

[0099] S601, during the welding process of replacing the steam generator, the welding start position is determined based on stress data.

[0100] During the welding process of replacing the steam generator, the data acquisition device collects stress data of the main pipeline and transmits the stress data to the remote terminal through the signal transmission cable. The remote terminal analyzes and calculates the stress data to determine the welding start position of the main pipeline.

[0101] S602, determine the position movement information based on the soldering start position.

[0102] The remote terminal determines the position movement information of the position control device based on the welding start position of the main pipeline, and then adjusts the position of the main pipeline according to the position movement information of the position control device.

[0103] In the above embodiments, during the welding process of replacing the steam generator, the welding start position is determined based on stress data, and the position movement information is determined based on the welding start position. Real-time monitoring of the stress changes in the main pipeline during the welding process via a remote terminal is a necessary condition for the remote terminal to formulate a precise welding plan, thereby enabling the main pipeline to be adjusted to the appropriate welding start position, making the entire process efficient and fast.

[0104] In one embodiment, such as Figure 8 The diagram shows the entire steam generator replacement process, including the following steps:

[0105] S701, obtain stress data for the main pipeline.

[0106] During the main pipeline cutting, beveling, and welding processes, the data acquisition device can acquire stress data in real time and transmit the stress data to a remote terminal via signal transmission cables.

[0107] S702, during the beveling process of replacing the steam generator, the assembly method and the beveling size of the main pipeline are determined based on stress data.

[0108] During the cutting, beveling, and welding of the main pipeline, the data acquisition device collects real-time stress data and transmits it to a remote terminal via a signal transmission cable. The remote terminal uses a preset algorithm to analyze and calculate the collected stress data, thereby determining the positional movement information of the main pipeline.

[0109] S703, during the welding process of replacing the steam generator, the welding start position is determined based on stress data.

[0110] During the welding process of replacing the steam generator, the data acquisition device collects stress data of the main pipeline and transmits the stress data to the remote terminal through the signal transmission cable. The remote terminal analyzes and calculates the stress data to determine the welding start position of the main pipeline.

[0111] S704, determine the position movement information of the main pipeline.

[0112] The remote terminal uses a preset algorithm to determine the location and movement information of the main pipeline.

[0113] S705, sends position movement information to the position control device, which instructs the position control device to move the main pipeline to align and install the main pipeline with the replacement steam generator.

[0114] The remote terminal sends position movement information to the controller via a signal transmission cable. The controller then drives the drive motor, which in turn moves the second support structure on the displacement platform in the X, Y, and Z directions. This adjusts the position of the main pipeline, making it easier to align the bevel of the main pipeline with the bevel of the steam generator during the bevel assembly process. Adaptively, this allows the main pipeline to be adjusted to the optimal welding position with the replaced steam generator during the welding process.

[0115] In the above embodiments, stress data of the main pipeline is acquired. During the beveling assembly process of replacing the steam generator, the assembly method and beveling size of the main pipeline are determined based on the stress data. During the welding process of replacing the steam generator, the welding start position is determined based on the stress data, and the position movement information of the main pipeline is determined. The position movement information is sent to the position control device, which is used to instruct the position control device to move the main pipeline to align and install it with the replaced steam generator. Through the embodiments of this application, when replacing an in-service steam generator, under radiation dose conditions, the steam generator replacement auxiliary device and method involved in the embodiments of this application can remotely automate the steps of fixing, monitoring, calculating, and adjusting, which is simple and fast, improves work efficiency, shortens the construction period, improves measurement accuracy, and effectively reduces the radiation dose to personnel. At the same time, when replacing an in-service steam generator, while fixing the main pipeline, the stress change of the main pipeline is remotely monitored in real time, which greatly facilitates the precise formulation of an effective implementation plan. It should be understood that although the steps in the flowcharts involved in the above embodiments are shown sequentially according to the arrow indications, these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise expressly stated herein, there is no strict order in which these steps are performed, and they may be performed in other orders.
