The method comprises: collecting real-time operation data of apparatuses in a power plant and structured and unstructured data related to the apparatuses; storing the data in a knowledge map, and establishing nodes of entities, attributes and relationships; and analyzing and processing the data in the knowledge map by using an artificial intelligence algorithm, so as to determine an apparatus fault and anomaly. When test block components are placed on a placement track by means of guide components, the test block components are connected to a power plant pipeline, so that the test block components are at a temperature approximate to that at which the power plant pipeline is; and when the current condition of the power plant pipeline needs to be monitored, the test block components can be taken out from the inner side of the placement track through an taking-out opening, and metallographic test analysis and stress test analysis are carried out on the test block components. The present invention uses the test block components instead of sampling a pipeline body, thereby avoiding the problem that the pipeline body is damaged.

[0060] Example 2

[0061] 1 to 3 , this embodiment differs from the first embodiment in that: the pipeline monitoring device includes the pipeline thermal aging monitoring mechanism in the above embodiment; it includes,

[0062] The positioning component 100 includes a first positioning member 101, a second positioning member 102 connected to the first positioning member 101, and a mounting track S formed on the first positioning member 101 and the second positioning member 102; the first positioning member 101 and the second positioning member 102 are both arc-shaped, and the arc angle is 150 degrees to 170 degrees. In this embodiment, 150 degrees is selected. Connecting protrusions are provided at both ends of the first positioning member 101 and the second positioning member 102, and connecting holes are opened on the connecting protrusions. The first positioning member 101 and the second positioning member 102 can be detachably connected through the connecting protrusions, connecting holes, bolts and nuts. The specific dimensions of the first positioning member 101 and the second positioning member 102 can be determined according to the diameter of the pipeline to be monitored. The entire device can be fixed to the outside of the pipeline through the first positioning component and the second positioning component.

[0063] The test component 200 includes a test block member 201 that can be slidably mounted on the mounting track S, and a guide assembly 202 mounted on the test block member 201. The material of the test block member 201 is the same as that of the power plant pipeline. When the test block member 201 is mounted on the mounting track S through the guide assembly, the test block member 201 is connected to the power plant pipeline, so that the test block member 201 is at a temperature similar to that of the power plant pipeline.

[0064] Among them, the second positioning member 102 is provided with an outlet 102a for conveniently removing the test block component 201 from the installation track S. When it is necessary to inspect the power plant pipeline, the test block component 201 is removed from the installation track S, and the test block component 201 is subjected to metallographic and mechanical testing and analysis, thereby obtaining a test structure close to the current state of the power plant pipeline. This testing method does not require destroying the power plant pipeline for testing and is easy to operate.

[0065] Specifically, a first through groove 101a is provided on the first positioning member 101, and a second through groove 102b is provided on the second positioning member 102; a first inner rail 101b is further provided in the first positioning member 101, and a second inner rail 102c is further provided in the second positioning member 102. When the first positioning member 101 and the second positioning member 102 are connected, the first inner rail 101b and the second inner rail 102c constitute a placement track S. In order to allow one side of the test block component 201 to directly contact the external environment, a first through groove 101a is provided on the first positioning member 101 and the second positioning member 102, respectively. 01a and the second through groove 102b, the first positioning member 101 and the second positioning member 102 are connected, the first positioning member 101 and the second positioning member 102 form a circular structure, and a circular placement track S is formed between the first positioning member 101 and the second positioning member 102. The test block component 201 is arc-shaped. In this embodiment, the number of test block components 201 is 12, and the 12 test block components 201 are all slidably arranged on the inner side of the placement track S. When the test block component 201 is located on the inner side of the placement track S, its outer arc surface contacts the external environment of the pipeline, and its inner arc surface contacts the pipeline.

[0066] When the current power plant pipeline conditions need to be monitored, the test block component 201 can be taken out from the inner side of the placement track S through the take-out outlet 102 a , and metallographic test analysis and stress test analysis can be performed on the test block component 201 .

[0067] The rest of the structure is the same as that of Example 1.

[0068] Operation process: The entire device can be fixed on the outside of the pipeline through the first positioning component and the second positioning component. When the test block component 201 is placed on the installation track S through the guide component, the test block component 201 is connected to the power plant pipeline, so that the test block component 201 is at a temperature similar to that of the power plant pipeline. When it is necessary to monitor the current power plant pipeline situation, the test block component 201 can be taken out from the inside of the installation track S through the removal outlet 102a, and the test block component 201 can be subjected to metallographic test analysis and force test analysis.

[0069] The test block component 201 is used to take samples instead of the pipeline body, thereby avoiding the problem of the pipeline body being damaged.

[0070] Example 3

[0071] 4 to 5, this embodiment is different from the above embodiment in that it further includes a pushing member 300, which includes a side rail 301 provided on the second positioning member 102, a rotating ring member 302 rotatably provided on the side rail 301, and a resisting pushing member 303 provided on the rotating ring member 302 and in contact with the test block member 201, wherein after the first positioning member 101 and the second positioning member 102 are connected, the first positioning member 101, the second positioning member 102, The side rails 301 and the rotating ring 302 are coaxial, and the placement track S is also coaxial with the above structure. In order to avoid the problem that the test block component 201 is located on the inner side of the placement track S and is difficult to be pushed to the removal outlet 102a, the rotation of the rotating ring 302 can drive the interference pusher 303 to push the test block component 201, so that the test block component 201 rotates on the inner side of the placement track S toward the removal outlet 102a until the test block component 201 farthest from the interference pusher 303 reaches the removal outlet 102a, and the test block component 201 can be taken out from the removal outlet 102a.

[0072] Specifically, the first inner rail 101b includes a first sub-rail body 101b-1 and a second sub-rail body 101b-2 provided inside the first positioning member 101; the second inner rail 102c includes a third sub-rail body 102c-1 and a fourth sub-rail body 102c-2 provided inside the second positioning member 102;

[0073] Among them, the first sub-rail body 101b-1, the second sub-rail body 101b-2, the third sub-rail body 102c-1, and the fourth sub-rail body 102c-2 are all arc-shaped. There is a gap between the first sub-rail body 101b-1 and the second sub-rail body 101b-2, and there is a gap between the third sub-rail body 102c-1 and the fourth sub-rail body 102c-2. Both gaps are placement gaps M. When the test block component 201 is located on the placement track S, it is located on the inner side of the placement gap M. It should be noted that a side rail groove L1 is provided on one side of the first sub-rail body 101b-1 and the third sub-rail body 102c-1, and the inner circular surface of the second sub-rail body 101b-2 and the fourth sub-rail body 102c-2 has an inner rail groove L2. Both the side rail groove L1 and the inner rail groove L2 are coaxial with the first positioning member 101, the second positioning member 102, and multiple sub-rail bodies.

[0074] The guide assembly 202 includes a first guide member 202a provided on one side of the test block member 201 and slidably connected to the inner side of the first sub-rail body 101b-1 / the third sub-rail body 102c-1, and a second guide member 202b provided on the other side of the test block member 201 and slidably connected to the inner side of the second sub-rail body 101b-2 / the fourth sub-rail body 102c-2.

[0075] The first guide member 202a includes a side shaft, the outer side of which is sleeved with a rolling ring, and the side shaft extends to the inner side of the side rail groove L1. The rolling ring fits against the groove wall of the side rail groove L1, achieving a guiding effect while reducing friction during movement. The second guide member 202b slides on the inner side of the inner rail groove L2.

[0076] The rest of the structure is the same as that of Example 2.

[0077] Operation process: In order to avoid the problem that the test block component 201 is located on the inner side of the installation track S and is difficult to be pushed to the removal outlet 102a, the rotation of the rotating ring 302 can drive the resistance pushing member 303 to push the test block component 201, so that the test block component 201 rotates on the inner side of the installation track S toward the removal outlet 102a until the test block component 201 farthest from the resistance pushing member 303 reaches the removal outlet 102a, and the test block component 201 can be taken out from the removal outlet 102a.

[0078] Example 4

[0079] 4 to 7 , this embodiment is different from the above embodiments in that it further includes a locking component 400. The purpose of providing the locking component 400 is to position the pushing component 300 after rotation, so that the interference pushing member 303 in the pushing component can maintain the interference state with the test block component 201, thereby avoiding the problem of the interference pushing member 303 and the test block component 201 being separated due to the rotation of the rotating ring 302 in the pushing component.

[0080] The locking component 400 includes an elastic component 401, which is arranged on the second positioning component 102; a through hole is opened on the second positioning component 102 at the corresponding position of the removal outlet 102a, and the elastic component 401 includes an external tube 401a fixed at the corresponding position of the through hole, a return spring 401b on the inner side of the external tube 401a, one end of which passes through the external tube 401a and the other end of which passes through the movable column 401c of the second positioning component 102, and an extrusion ring 401d is also fixed on the outer side of the movable column 401c, and the extrusion ring 401d is in conflict with the return spring 401b.

[0081] The limiting assembly 402 includes a limiting rod 402a connected to the elastic assembly 401, and a positioning column 402b provided on the limiting rod 402a. The limiting rod 402a and the movable column 401c are connected to one end of the second positioning member 102, and the limiting rod 402a is L-shaped. The end away from the movable column 401c slides through the second positioning member 102 and remains parallel to the movable column 401c. The positioning column 402b extends toward the rotating ring 302.

[0082] The rotating ring 302 includes a limiting ring 302a rotatably connected to the side rail 301, an inner ring 302b connected to the limiting ring 302a, and a positioning inner frame 302c circumferentially distributed between the limiting ring 302a and the inner ring 302b.

[0083] The positioning column 402b extends to the inner side of the limiting ring body 302a and the built-in ring body 302b, and the two ends of its positioning inner frame 302c are connected to the limiting ring body 302a. It consists of three sections, namely the lifting section N1, the translation section N2, and the separation section N3. The lifting section N1 is tilted and extends toward the built-in ring body 302b. One end of the translation section N2 is connected to the lifting section N1, and the other end is connected to the separation section N3, and the separation section N3 is perpendicular to the translation section N2.

[0084] An annular groove 301a is provided on the inner wall of the side rail 301, and a snap ring 302a-1 is integrally formed on the outer wall of the limiting ring body 302a. The snap ring 302a-1 is rotatably connected to the inner side of the annular groove 301a. The snap ring 302a-1 rotates on the inner side of the annular groove 301a, so that the limiting ring body 302a can rotate and cannot be detached. The limiting ring body 302a is connected to the built-in ring body 302b. When the limiting ring body 302a rotates, it can drive the built-in ring body 302b to rotate synchronously, which drives the positioning inner frame 302c to rotate synchronously.

[0085] During the rotation of the limiting ring 302a and the internal ring 302b in the first direction, the resisting pusher 303 is driven to push the test block component 201, so that the test block component 201 rotates in the first direction to reach the removal outlet 102a.

[0086] It should be noted that there are multiple positioning inner frames 302c, and they correspond one to one with the positions of the test block components 201. The rest of the structure is the same as that of the third embodiment.

[0087] Operation process: In the process of rotating the ring 302 to push the test block component 201, the positioning column 402b will first contact the lifting section N1. Under the action of the lifting section N1, the positioning column 402b drives the limiting rod 402a and the movable column 401c to move, and the movable column 401c drives the extrusion ring 401d to press the reset spring 401b, causing the reset spring 401b to deform. When the position of the test block component 201 corresponds to the position of the removal port 102a, the positioning column 402b disengages from the translation section N2. At this time, the reset spring 401b pushes the extrusion ring 401d, causing the movable column 401c to rebound quickly, thereby driving the positioning column 402b through the limiting rod 402a to rebound quickly. At this time, the positioning column 402b contacts the disengagement section N3, avoiding the problem of the rotating ring 302 rotating.

[0088] Example 5

[0089] 6 and 7 to 9 , this embodiment is different from the above embodiments in that in order to avoid the problem of the test block component 201 remaining on the inner side of the mounting track S being detached, the present device further includes an anti-detachment component 500, including a fixed shaft 501 fixed on the second positioning member 102, and a swinging component 502 rotatably sleeved on the fixed shaft 501; the swinging component 502 is connected to the limiting rod 402a, and during the sliding process of the limiting rod 402a, it can drive the swinging component 502 to swing, and the swinging component 502 swings up to be able to detach from the test component 200, and the swinging frame swings down to be able to resist and position the test component 200.

[0090] The second guide member 202b includes an extension column 202b-1 fixed to the test block member 201, and a sliding block 202b-2 that is sleeved on the outside of the extension column 202b-1 and slidably connected to the second sub-rail body 101b-2 / the fourth sub-rail body 102c-2; the sliding block 202b-2 can slide inside the inner sliding grooves on the second sub-rail body 101b-2 and the fourth sub-rail body 102c-2.

[0091] One end of the swing member 502 is connected to the limit rod 402a, and the other end can contact the extension column 202b-1 to position the test block component 201. The end of the swing member 502 connected to the limit rod 402a is the fine-motion end 502a, and a fine-motion groove 402a-1 is provided on the limit rod 402a. The fine-motion end 502a and the fine-motion groove 402a-1 are slidingly connected. The end of the swing member 502 away from the fine-motion end 502a is the contact end 502b. When the limit rod 402a moves upward, it can drive the fine-motion end 502a to rotate upward, thereby causing the swing member 502 to swing downward, and the contact end 502b contacts the extension column 202b-1. When the limit rod 402a moves downward, it can drive the fine-motion end 502a to move downward, thereby driving the swing member 502 to swing upward, so that the contact end 502b is separated from the extension column 202b-1.

[0092] A recovery groove 102d is provided on the second positioning member 102, and the contact end 502b has an inwardly protruding inner extension protrusion 502b-1. The inner extension protrusion 502b-1 can enable the contact end 502b to contact the extension column 202b-1 when it swings down, and can enter the inner side of the recovery groove 102d when it swings up, thereby preventing the inner extension protrusion 502b-1 from hindering the movement of the test block component 201.

[0093] Furthermore, an abutment protrusion 402a-2 is provided on the side wall of the limiting rod 402a, and the removal port 102a penetrates the inner rail groove L2 and the side rail groove L1, so that the guide assembly 202 can be detached from the inner side of the inner rail groove L2 and the side rail groove L1.

[0094] When the test block component 201 reaches the corresponding position of the removal outlet 102a, the positioning column 402b is separated from the translation section N2. At this time, the return spring 401b drives the movable column 401c to move upward through the extrusion ring 401d, thereby driving the limit rod 402a to move upward. At this time, the interference protrusion 402a-2 can move upward with the limit rod 402a, and the interference protrusion 402a-2 is located at the extension column 202b-1 of the test block component 201 at the removal outlet 102a position. Therefore, the extension column 202b-1 is subjected to force and drives the test block component 201 to move upward. The block component 201 moves upward, and the test block component 201 detaches from the installation track S from the removal outlet 102a, preventing people from taking the test block component 201. During this process, the limit rod 402a moves upward, which can drive the swing component 502 to swing downward, and interfere with and limit the test block component 201 remaining in the installation track S. At this time, the remaining test block component 201 is limited between the anti-detachment component 500 and the interference pusher 303, thereby avoiding the problem of the remaining test block component 201 detaching from the inner side of the installation track S.

[0095] Specifically, the resisting pusher 303 includes a synchronous tube 303a fixed on the rotating ring 302, an internal spring 303b arranged inside the synchronous tube 303a, and a pushing column 303c whose one end resists the test block component 201 and the other end extends to the inside of the synchronous tube 303a and resists the internal spring 303b.

[0096] Among them, the synchronous tube 303a and the pushing column 303c are coaxial with the second positioning member 102 and the first positioning member 101. When the swinging member 502 is in a state of interference and limitation with the extension column 202b-1, the ring 302 can be rotated in the first direction, and the synchronous tube 303a is driven to rotate in the first direction. Because the test block component 201 is in a state of interference and positioning by the swinging member 502, the pushing column 303c that is in conflict with the test block component 201 cannot move, and the built-in spring 303b will be compressed by the pushing column 303c and the synchronous tube 303a.

[0097] During the rotation of the positioning inner frame 302c, the lifting section N1 will contact the positioning column 402b, causing the positioning column 402b to move downward, driving the limit rod 402a and the movable column 401c to move downward, and at this time driving the swing component 502 to swing upward, releasing the resistance to the test block component 201, and the elastic force of the built-in spring 303b will be instantly applied to the test block component 201 through the pushing column 303c, pushing the test block component 201 to rotate.

[0098] The rest of the structure is the same as that of Example 4.

[0099] Operation process: When the test block component 201 reaches the corresponding position of the removal outlet 102a, the positioning column 402b is separated from the translation section N2. At this time, the return spring 401b drives the movable column 401c to move upward through the extrusion ring 401d, thereby driving the limit rod 402a to move upward. At this time, the interference protrusion 402a-2 can move upward with the limit rod 402a, and the interference protrusion 402a-2 is located at the extension column 202b-1 of the test block component 201 at the position of the removal outlet 102a, so that the extension column 202b-1 is subjected to force and moves upward. The movable test block component 201 moves upward, and the test block component 201 detaches from the installation track S from the removal outlet 102a, preventing people from taking the test block component 201. During this process, the limiting rod 402a moves upward, which can drive the swinging component 502 to swing downward, and interfere with and limit the test block component 201 remaining in the installation track S. At this time, the remaining test block component 201 is limited between the anti-detachment component 500 and the interference pusher 303, thereby preventing the remaining test block component 201 from detaching from the inner side of the installation track S.
