[0033] To make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following describes this application in further detail with reference to the accompanying drawings and embodiments.

[0034] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0039] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0040] To address the technical problem that relying solely on manual inspection of the blade surface with a probe results in extremely low overall inspection efficiency and makes it difficult to conduct comprehensive and detailed inspections of the rotor blades, easily leading to missed inspections of certain blade surfaces and consequently low overall accuracy, this utility model provides an inspection device for nuclear power plant rotors.

[0041] The following describes in detail the specific structure of a detection device for a nuclear power plant rotor provided by an embodiment of this utility model, according to the appendix. Figures 1-6 As shown, the specific structure of the detection device for the nuclear power plant rotor includes a base 1, a support assembly 2, an arm assembly 3, and a detection assembly 4.

[0042] By setting the support assembly 2, the arm body assembly 3, and the detection assembly 4 on the top surface of the seat body 1, the support assembly 2, the arm body assembly 3, and the detection assembly 4 can be stably supported, ensuring that the support assembly 2, the arm body assembly 3, and the detection assembly 4 remain in a fixed position and posture during the detection of the rotor, preventing such components from shaking, shifting, or falling, and providing a stable basis for the detection work. For example, by setting the support assembly 2 and the arm body assembly 3 on the support seat body 1, the operator can conveniently operate the arm body assembly 3 near the support seat body 1 to control the movement of the detection assembly 4, which can improve the efficiency of the detection work and reduce the labor intensity and operation risk of the operator.

[0043] According to Figure 2 As shown in FIG. 1, the support assembly 2 is arranged on the top surface of the seat body 1; the support assembly 2 includes a support column 21, a first driver 22, and a rotating seat 23; the support column 21 is arranged on the top of the rotating seat 23, the rotating seat 23 is rotationally arranged on the top surface of the seat body 1, and the first driver 22 is drivingly connected with the rotating seat 23 to drive the rotating seat 23 to rotate around its circumferential direction.

[0044] Specifically, when the first driver 22 is started, the output power of the first driver 22 can be transmitted to the rotating seat 23 due to the driving connection between the first driver 22 and the rotating seat 23, thereby driving the rotating seat 23 to rotate around its own central axis on the top surface of the seat body 1. This arrangement can flexibly adjust the angle and position of the support column 21 and the arm body assembly 3 connected thereto according to the detection requirements of the rotor, so that the detection assembly 4 can conveniently detect or operate the rotor from different angles.

[0045] In the foregoing embodiment, since the support column 21 is located on the top of the rotating seat 23, when the rotating seat 23 rotates, the support column 21 also rotates with it. The support column 21 plays a role in bearing and positioning, which is used to bear the arm body assembly 3 and the detection assembly 4 arranged on the arm body assembly 3, and stably supports the arm body assembly 3 to ensure that the arm body assembly 3 can move up and down smoothly on it.

[0046] According to Figure 4 As shown in FIG. 1, the arm body assembly 3 includes a first arm body 31, a second arm body 32, and a second driver 33; the first arm body 31 is arranged on the outside of the support column 21 in a lifting manner, and the second driver 33 is drivingly connected with the first arm body 31 to drive the first arm body 31 to move up and down; the first arm body 31 is formed with an extension cavity, and the second arm body 32 is movably arranged in the extension cavity.

[0047] Specifically, the first arm body 31 and the second arm body 32 are driven to ascend or descend along the side wall of the support column 21 by the second driver 33, and specifically, when the second driver 33 is started, the power output by the second driver 33 can drive the first arm body 31 to ascend or descend linearly along the outer side of the support column 21. Since the first arm body 31 is arranged to ascend or descend along the outer side of the support column 21, the first arm body 31 provides basic support for the entire arm body assembly 3 and also plays a guiding role in the ascending and descending movement along the support column 21, ensuring that the movement direction of the arm body assembly 3 is perpendicular to the seat body 1, making the detection process more stable and accurate. During detection, only the ascending and descending movement of the first arm body 31 on the support column 21 is required to adjust the height position of the entire arm body assembly 3, so that the detection assembly 4 can reach different height positions of the rotor of the nuclear power plant for detection, adapt to rotors of different sizes and installation positions, and expand the application range of the detection device. The second arm body 32 can move in the telescopic cavity of the first arm body 31, so that the detection assembly 4 can be more flexible to approach or move away from the rotor, not only can detect the surface of the rotor, but also can detect some internal space or narrow area of the rotor when necessary. In combination with the ascending and descending function of the first arm body 31, the telescopic function of the second arm body 32 can more accurately position the detection assembly 4, so that the detection assembly 4 can accurately align with the specific part or key area of the rotor that needs to be detected, and improve the accuracy of detection.

[0048] According to Figure 1 As shown in FIG. 4, the detection assembly 4 is arranged at one end of the second arm body 32, and specifically, since the detection assembly 4 is arranged at one end of the second arm body 32, the detection assembly 4 can move to different detection positions of the rotor along with the movement of the arm body assembly 3, and detect the physical properties, surface conditions and the like of the rotor to obtain data information about the structural integrity, material performance, surface defects and the like of the rotor.

[0049] It can be understood that the detection assembly 4 of the embodiment of the utility model includes various sensors, such as ultrasonic sensors, eddy current sensors, visual sensors and the like, and the specific type is not limited herein.

[0050] According to Figure 1 As shown in FIG. 5, in some specific embodiments, the seat body 1 of the embodiment of the utility model is provided with a moving assembly 5. It can be understood that the moving assembly 5 includes a plurality of rolling wheels, and each rolling wheel is arranged at the bottom of the base to assist the movement of the seat body 1.

[0051] According to Figure 3As shown, in some specific embodiments, the first driver 22 comprises a first motor 221, a first driving wheel 222 and a first driven wheel 223; the first motor 221 is arranged in the seat body 1, the first driving wheel 222 is sleeved on the power output shaft of the first motor 221, and the first driven wheel 223 is arranged in the rotating seat 23, and the first driving wheel 222 is engaged with the first driven wheel 223.

[0052] Specifically, the first motor 221 converts electrical energy into mechanical energy, outputs rotary power through its power output shaft, adjusts the output speed and torque according to the actual control requirements, so as to realize the rotation of the rotating seat 23 at different speeds and accuracies, the first driving wheel 222 is sleeved on the power output shaft of the first motor 221, which can rotate synchronously with the power output shaft of the first motor 221, and is used for transmitting the rotary power output by the first motor 221 to the first driven wheel 223, since the first driven wheel 223 is arranged in the rotating seat 23, the first driven wheel 223 is engaged with the first driving wheel 222, so that when the first driving wheel 222 rotates, the power is transmitted to the first driven wheel 223 through the interaction between the first driving wheel 222 and the first driven wheel 223, thereby driving the rotating seat 23 to rotate.

[0053] More specifically, in operation, the first motor 221 starts to rotate the power output shaft, since the first driving wheel 222 is sleeved on the power output shaft of the first motor 221, the first driving wheel 222 rotates with the first motor 221, the first driving wheel 222 is engaged with the first driven wheel 223, the teeth of the first driving wheel 222 push the teeth of the first driven wheel 223, thereby transmitting the rotary motion of the first driving wheel 222 to the first driven wheel 223, since the first driven wheel 223 is arranged in the rotating seat 23, when the first driven wheel 223 rotates, the rotating seat 23 rotates around the central axis on the top surface of the seat body 1. Since the support column 21 is arranged on the top of the rotating seat 23, the support column 21 rotates with the rotating seat 23, thereby realizing the angle adjustment of the arm body assembly 3 and the detection assembly 4.

[0054] Therefore, by rotating the rotating seat 23 through the first driver 22, the detection assembly 4 can be flexibly adjusted to different angle positions, and each side surface of the rotor can be comprehensively detected, so as to ensure that the damage, cracks and other problems on the surface or inside of the rotor can be found in time, thereby improving the accuracy and reliability of the detection.

[0055] According to Figure 3 As shown, in further embodiments, the seat body 1 is provided with a first support frame 11 for supporting the first motor 221.

[0056] Specifically, by the first support frame 11 for stably fixing the first motor 221 in a designated position in the seat body 1, it is ensured that the motor is difficult to move or shake during operation, and the relative position accuracy of the first motor 221 and other components (such as the first driving wheel 222, the power output shaft, etc.) is ensured, so that the first driving wheel 222 and other components such as the first driven wheel 223 maintain stable engagement, avoiding problems such as gear misalignment and poor transmission.

[0057] According to Figure 4 As shown in FIG. 11, in some specific embodiments, the second driver 33 includes a connecting piece 331, a straight rack 332, a second motor 333, and a second driven wheel 334; the straight rack 332 is vertically oriented and arranged on the support column 21, the connecting piece 331 is movably arranged on the support column 21, the second motor 333 is arranged on the connecting piece 331, the second driven wheel 334 is sleeved on the power output shaft of the second motor 333, and the second driven wheel 334 is engaged with the straight rack 332; one end of the first arm body 31 is connected to the connecting piece 331.

[0058] Specifically, when the power output shaft of the second motor 333 rotates, it can transmit power to the second driven wheel 334. Since the second driven wheel 334 is engaged with the vertically oriented straight rack 332, when the power output shaft of the second motor 333 rotates, it is converted into linear motion of the second driven wheel 334, thereby driving the connecting piece 331 to move up and down on the support column 21. Since the first arm body 31 is connected to the connecting piece 331, the connecting piece 331 can drive the first arm body 31 to move up and down when it moves up and down. More specifically, when the second motor 333 drives the second driven wheel 334 to rotate clockwise, the teeth of the second driven wheel 334 interact with the teeth of the straight rack 332, generating an upward pushing force to push the connecting piece 331 to move upward along the support column 21. Conversely, when the second motor 333 drives the second driven wheel 334 to rotate counterclockwise, the teeth of the second driven wheel 334 interact with the teeth of the straight rack 332, generating a downward pushing force to push the connecting piece 331 to move downward along the support column 21. In this way, the first arm body 31 is driven to move up and down to different heights to meet detection requirements, for example, different height parts of a nuclear power plant rotor can be detected.

[0059] According to Figure 6 As shown in FIG. 12, in further embodiments, the bottom surface of the telescopic cavity is provided with a guide rail 311, and the bottom surface of the second arm body 32 is provided with a sliding piece 34 for sliding on the guide rail 311; the arm body assembly 3 further includes a third driver 35, which is drivingly connected to the second arm body 32.

[0060] Specifically, when the second arm body 32 needs to be moved in extension and retraction, the third driver 35 is used to drive the second arm body 32 to move in the extension and retraction cavity of the first arm body 31. Since the sliding piece 34 at the bottom surface of the second arm body 32 is slidably arranged on the guide rail 311 at the bottom surface of the extension and retraction cavity, the guide rail 311 is used to constrain and guide the sliding piece 34, so that the second arm body 32 can only move linearly along the length of the guide rail 311. In this way, the second arm body 32 can be moved in extension and retraction in the extension and retraction cavity of the first arm body 31, so as to further expand the detection range of the detection assembly 4. By adjusting the position of the second arm body 32, the detection assembly 4 can detect different target detection positions of the rotor.

[0061] It can be understood that the guide rail 311 of the embodiment of the utility model is in a groove shape, a rib shape or a track shape, and the specific shape is not limited here, which is used to provide a guiding movement path for the sliding piece 34. Correspondingly, the shape and size of the sliding piece 34 are matched with the guide rail 311, so that the sliding piece 34 can be closely arranged on the guide rail 311.

[0062] According to Figure 6 As shown in FIG. 6, in a further embodiment, the third driver 35 includes a lead screw 351, a nut 352 and a driving structure 353. The driving structure 353 is arranged on the connecting piece 331, the driving structure 353 is drivingly connected with one end of the lead screw 351, the other end of the lead screw 351 is arranged in the second arm body 32, and the nut 352 is arranged outside the second arm body 32 and is sleeved on the outside of the lead screw 351.

[0063] Specifically, the driving structure 353 can accurately provide adjustable power for driving the second arm body 32 to move. Specifically, since the driving structure 353 is drivingly connected with one end of the lead screw 351, when the driving structure 353 outputs power, the lead screw 351 will rotate along its circumference under the driving of the driving structure 353. The outside of the lead screw 351 is provided with threads, the nut 352 is sleeved on the outside of the lead screw 351, and the nut 352 is engaged with the threads of the lead screw 351. Since the nut 352 is fixedly connected with the second arm body 32, the second arm body 32 cannot rotate due to the restriction of the guide rail 311 and other structures. When the lead screw 351 rotates, the nut 352 moves linearly along the axis of the lead screw 351 under the action of the threads of the lead screw 351. The linear movement of the nut 352 can drive the second arm body 32 to move.

[0064] It is to be noted that, if the screw rod 351 rotates clockwise, the nut 352 moves along the axis of the screw rod 351, thereby pushing the second arm body 32, and the second arm body 32 is guided by the guide rail 311 to move along the length of the guide rail 311; conversely, if the screw rod 351 rotates counterclockwise, the nut 352 moves in the opposite direction to drive the second arm body 32 to move in the opposite direction. By controlling the forward and reverse rotation of the screw rod 351 driven by the driving structure 353 and the number of rotations or angles, the moving direction and distance of the nut 352 and the second arm body 32 can be accurately controlled, the accurate movement of the second arm body 32 on the guide rail 311 is realized, and thus the effective detection range of the detection assembly 4 is expanded, and each part of the rotor is detected in detail.

[0065] According to Figure 5 and Figure 6 Specifically, the driving structure 353 includes a third motor 3531, a third driving wheel 3532, a transmission wheel 3533 and a third driven wheel 3534; the third motor 3531 is arranged at the bottom of the connecting piece 331, the third driving wheel 3532 is sleeved on the power output shaft of the third motor 3531, the third driven wheel 3534 is sleeved on one end of the screw rod 351, and the transmission wheel 3533 is engaged with the third driving wheel 3532 and the third driven wheel 3534.

[0066] Specifically, the third driving wheel 3532 is sleeved on the power output shaft of the third motor 3531 and can rotate with the power output shaft. The transmission wheel 3533 serves as an intermediate transition, and is engaged with the third driving wheel 3532 and the third driven wheel 3534 at the same time. When the third driving wheel 3532 rotates, the transmission wheel 3533 can transmit power to the third driven wheel 3534, thereby realizing multi-stage power transmission. Since the third driven wheel 3534 is sleeved on one end of the screw rod 351, when the third driven wheel 3534 rotates under the driving of the transmission wheel 3533, the screw rod 351 can be driven to rotate. Through the rotation of the screw rod 351 and the cooperation with the nut 352, the rotation power of the third motor 3531 can be converted into the power for pushing the second arm body 32 to move linearly, so that the detection assembly 4 can move to the specified detection position.

[0067] It is to be noted that the outer side of the first arm body 31 is provided with a connecting shaft 3535, and the transmission wheel 3533 is rotatably sleeved on the connecting shaft 3535.

[0068] Specifically, since the transmission wheel 3533 plays a role in transmitting power in the entire driving structure 353, the connecting shaft 3535 is used to support the transmission wheel 3533, so that the transmission wheel 3533 can stably rotate, and the transmission wheel 3533 is prevented from shaking or deviating during rotation, thereby ensuring the stability and accuracy of power transmission.

[0069] In the foregoing embodiment, the bottom of the connecting piece 331 is provided with a second support frame for supporting the third motor 3531. Specifically, in order to ensure that the third motor 3531 can stably operate, and avoid sagging, shaking or displacement due to its weight, the second support frame is used to support the third motor 3531, and can also serve as a positioning reference for the assembly position of the third motor 3531. By assembling the third motor 3531 to the second support frame, the relative positional relationship between the third motor 3531 and other transmission components (such as the third driving wheel 3532, the transmission wheel 3533 and the third driven wheel 3534, etc.) can be ensured, and the correct engagement and transmission between the components can be ensured.

[0070] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
