Description

Technical Field

[0001] The invention relates to the field of nuclear power, and in particular to a remote auxiliary fixing device for nuclear power. Background Art

[0002] Nuclear reactors are important facilities for generating electricity using energy generated by nuclear fission or nuclear fusion. During the operation of nuclear power plants, it is crucial to ensure the safe and efficient operation of nuclear reactors. To achieve this, it is necessary to accurately monitor the status within the core, including key parameters such as neutron flux distribution, temperature, and coolant water level. Therefore, the core measurement system has become an indispensable part of nuclear reactors.

[0003] The core measurement system usually includes multiple types of detector assemblies, such as high-level detector assemblies, which are installed inside the upper reactor internals and can provide key information about the core condition. These detector assemblies must be able to operate under extreme conditions, such as high temperature environments and high radiation dose conditions. However, under such working conditions, the detectors need to be replaced in a timely manner within a certain period to ensure the reliability of the core measurement system. However, certain technical problems were encountered when actually performing this maintenance task:

[0004] When it is necessary to replace the high-level radioactive detector or other components in the upper internals, the component is often in a position that is difficult to directly contact - that is, most of the structure is immersed in water, and there is a lack of effective auxiliary support devices to fix this component weighing several tons or even heavier. Under the traditional method, although a special disassembly device for the high-level radioactive detector can be installed on a platform or other auxiliary devices, the upper internals themselves lack sufficient support, so it is easy to damage the internals when disassembling the high-level radioactive detector. At the same time, the lack of manufactured internals makes it difficult to maintain the stability required for disassembly during the disassembly process, which seriously affects the disassembly efficiency. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a nuclear power remote auxiliary fixing device, which can solve the technical problem that the internal components of the reactor are easily damaged and unstable during the process of disassembling the parts thereon due to lack of support, thus affecting the disassembly.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] Figure 1 and Figure 2 The nuclear power remote auxiliary fixing device 10 in some embodiments of the present invention is shown, and the nuclear power remote auxiliary fixing device 10 is arranged on a nuclear power facility platform or other auxiliary device, wherein both the nuclear power facility platform and the auxiliary device can provide stable support. For example, the auxiliary device can be a stable and reliable lifting mechanism or a stable extension platform on the nuclear power facility platform.

[0047] like Figure 1 and Figure 2 As shown, the nuclear power remote auxiliary fixing device 10 includes a base 1, an adjustment component 2, a screwing component 3 and a support component 4. The base 1 is connected to the nuclear power facility platform or other auxiliary devices, so that the base 1 can be set in a stable and reliable position that is not easy to deviate, and then the remaining components can obtain reliable support through the base 1 to ensure the subsequent stable and reliable connection with the upper internal components. The adjustment component 2 is movably arranged on the base 1, the screwing component 3 is movably arranged on the adjustment component 2, and the support component 4 is connected to the screwing component 3.

[0048] It should be noted that the adjustment component 2 is used to adjust the angle of the screwing component 3, so that the screwing component 3 drives the support component 4 to rotate and adjust the angle. The screwing component 3 is used to drive the support component 4 to move up and down during the rotation process. The support component 4 is used to form a stable and reliable support between the base 1 and the upper internal components.

[0049] It can be understood that the upper internal components and the support assembly 4 can be configured to be connected through a special plug-in structure (such as a socket and a plug post, and a structure with a locking function is provided between the socket and the plug post) to ensure that the support assembly 4 can provide stable and reliable support.

[0050] like Figures 2 to 8 As shown, the adjustment assembly 2 includes an adjustment seat 21 and a circumferential positioning member 22. The adjustment seat 21 is rotatably disposed on the base 1, and the circumferential positioning member 22 is movably disposed on the base 1. The circumferential positioning member 22 is detachably supported on the adjustment seat 21 to lock the relative position of the adjustment seat 21 and the base 1.

[0051] The screwing assembly 3 includes a screwing member 31 and a connecting member 32 . The screwing member 31 is movably connected to the connecting member 32 , and the screwing member 31 is threadedly connected to the adjustment seat 21 .

[0052] The support assembly 4 includes a support tube 41, a connecting seat 42 and a linear connecting structure 43. One end of the support tube 41 is connected to the connecting piece 32, and the other end of the support tube 41 is connected to the connecting seat 42. The linear connecting structure 43 is arranged between the support tube 41 and the adjustment seat 21. The connecting seat 42 is detachably connected to the upper in-pile component.

[0053] When the screwing member 31 rotates, the connecting member 32 is driven to move through the linear connection structure 43, thereby driving the connecting seat 42 to move toward or away from the upper in-pile component through the support tube 41; when the adjustment seat 21 rotates, the support tube 41 is driven to rotate through the linear connection structure 43, thereby driving the connecting seat 42 to rotate and lock or unlock with the upper in-pile component.

[0054] It can be understood that the adjustment seat 21 is rotatably arranged on the base 1 through a bearing or a similar mechanism, and can rotate around an axis. This design allows the user to adjust the angle of the support tube 41 as needed, so that the support tube 41 can be installed to the upper internal component at a predetermined angle. Of course, if the support tube 41 needs to be connected to the upper internal component by rotation, this rotation connection method also enables the support tube 41 to complete the connection smoothly. Of course, the adjustment seat 21 and the base 1 can also be connected by a ring groove and a structure inserted in the ring groove to achieve rotation connection.

[0055] The circumferential positioning member 22 is movably arranged on the base 1 and can abut against the outer side of the adjustment seat 21. When a suitable position is found, the position of the adjustment seat 21 relative to the base 1 can be locked by tightening the circumferential positioning member 22 to prevent it from accidentally rotating during operation.

[0056] The screwing member 31 is a component with a thread, such as a screw or a threaded rod, which is screwed onto the adjusting seat 21. The screwing member 31 can be moved forward or backward in the axial direction by rotating it manually or with an electric tool.

[0057] The connecting member 32 is directly connected to the screw member 31 and moves in a linear direction with the rotation of the screw member 31. This linear motion is transmitted to the support cylinder 41, thereby affecting the position of the connecting seat 42.

[0058] The support tube 41 is the main load-bearing structure, one end of which is connected to the connecting member 32, and the other end is connected to the connecting seat 42. When the screwing member 31 rotates, the support tube 41 moves along the direction of the linear connecting structure 43, so that the connecting seat 42 is close to or away from the upper internal component.

[0059] The connection seat 42 is the part that directly contacts the upper internal component and is designed to be detachable for easy installation and removal. It can be a clamp, a magnetic chuck or other forms of connection devices. The connection seat 42 is used to connect with the upper internal component.

[0060] The linear connection structure 43 is disposed between the support tube 41 and the adjustment seat 21, ensuring the linear movement of the support tube 41. The structure can be configured as a slide rail, a guide column, etc., to ensure that the support tube 41 moves smoothly along a predetermined path.

[0061] It should be noted that when the orientation of the support tube 41 needs to be adjusted, the connecting seat 42 can be driven to rotate by rotating the adjustment seat 21, so that the connecting seat 42 can be inserted into the upper internal component at a predetermined angle, and after the upper internal component is inserted, it can be rotated a certain distance to connect the connecting seat 42 to the upper internal component.

[0062] Subsequently, the circumferential positioning member 22 is used to fix the positions of the base 1 and the adjustment seat 21 to prevent the adjustment seat 21 from driving the support tube 41 to rotate, thereby preventing the connection seat 42 from escaping from the upper internal components.

[0063] When the height of the support tube 41 needs to be adjusted, the connection member 32 can be moved in a straight line by rotating the screw member 31, which will cause the support tube 41 to move accordingly, and finally change the distance between the connection seat 42 and the upper internal component. During this movement, the linear connection structure 43 can prevent the screw member 31 from driving the support tube 41 to rotate, so that the support tube 41 can move in a straight line.

[0064] It should also be noted that the screwing member 31 is movably connected to the connecting member 32, which means that the screwing member 31 movably abuts against the connecting member 32. The screwing member 31 will rub against the connecting member 32 during the rotation process, but the connecting member 32 cannot rotate synchronously due to the setting of the linear connection structure 43, and the connecting member 32 will only move along a straight line driven by the screwing member 31. Furthermore, the connecting member 32 and the screwing member 31 can be respectively provided with bosses (a first boss 91 and a second boss 92), the screwing member 31 passes through the connecting member 32, and the bosses of the two movably abut against each other.

[0065] like Figures 3 to 6 As shown, in some embodiments of the nuclear power remote auxiliary fixing device 10, the adjustment seat 21 includes an adjustment cylinder 211, an adjustment skirt 212, an adjustment seat 213 and a plurality of columns 214. The peripheral side wall of the adjustment cylinder 211 extends outward to form the adjustment skirt 212. One end of each column 214 is connected to the adjustment skirt 212, and the other end of each column 214 is connected to the adjustment seat 213.

[0066] The screwing member 31 passes through the adjusting tube 211 , and is screwed to the adjusting tube 211 . The linear connection structure 43 is used to limit the support tube 41 to slide along the height extension direction of the adjusting tube 211 .

[0067] It can be understood that the adjustment cylinder 211 is the main part of the adjustment seat 21, which is rotatably arranged on the base 1 through a bearing or a similar mechanism and can rotate around an axis. This design allows the user to adjust the angle of the support cylinder 41 as needed to adapt to the internal components of different shapes and positions. Of course, the adjustment cylinder 211 and the base 1 can also be connected through other rotating connection structures in the prior art, such as an annular groove and an insert block inserted into the annular groove to achieve a rotating connection.

[0068] The peripheral sidewall of the adjustment tube 211 extends outward to form an adjustment skirt 212. The adjustment skirt 212 not only increases the structural strength of the adjustment tube 211, but also provides a platform connected to the column 214, ensuring the stability and rigidity of the entire adjustment seat 21.

[0069] One end of each column 214 is connected to the adjustment skirt 212, and the other end is connected to the adjustment seat 213. The function of the column 214 is to firmly connect the adjustment skirt 212 and the adjustment seat 213 together to form an integral structure so that the two can rotate synchronously. The number and location of the columns 214 can be adjusted according to actual needs to ensure sufficient structural strength and stability.

[0070] The adjustment seat 213 is the other end connection point of the column 214 , and the adjustment seat 213 can move synchronously with the rotation of the adjustment cylinder 211 .

[0071] It should be noted that the linear connection structure 43 is used to limit the support tube 41 to slide along the height extension direction of the adjustment tube 211. The structure can be configured as a slide rail, a guide column, etc. to ensure that the support tube 41 moves smoothly along a predetermined path. The existence of the linear connection structure 43 ensures that when the screwing member 31 rotates, the support tube 41 does not rotate unnecessarily, but moves precisely up and down along a linear direction.

[0072] Furthermore, in some embodiments, the adjusting cylinder 211, the adjusting skirt 212, the adjusting seat 213 and each column 214 may be configured as an integrally formed structure. It can be understood that the content of this type of embodiment improves the connection strength between the structural parts.

[0073] like Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments of the nuclear power remote auxiliary fixing device 10, the adjustment assembly 2 also includes a plurality of adjustment handles 23, each adjustment handle 23 is arranged on the adjustment seat 21, and each adjustment handle 23 is equidistantly distributed along the outer side of the circumference of the adjustment seat 21.

[0074] It can be understood that the position setting of each adjustment handle 23 not only facilitates the operator to apply force, but also ensures the balance and uniform force during the rotation process. The number of adjustment handles 23 can be flexibly set, and the specific number can be adjusted according to actual needs and operating space. For example, five, six or even more can be set to provide more operating points, so that the operator can operate the adjustment handle 23 at a wider angle, making the rotation of the adjustment seat 21 more stable and controllable.

[0075] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of the nuclear power remote auxiliary fixing device 10, the linear connection structure 43 includes a guide groove 431 and a guide block 432, the guide groove 431 is arranged on the support tube 41, the guide block 432 is arranged on the adjustment seat 21, the guide block 432 is inserted into the guide groove 431, and the guide block 432 slides against the groove wall of the guide groove 431.

[0076] It can be understood that the guide groove 431 is provided on the support tube 41, and generally extends along the height direction of the support tube 41. The guide groove 431 can be designed as a straight groove or a groove with a certain shape (such as a T-shaped groove, a dovetail groove, etc.) to ensure that the guide block slides stably therein. The shape of the guide block matches the guide groove 431 to ensure that it can slide smoothly in the guide groove 431. The guide block slides against the groove wall of the guide groove 431, thereby limiting the rotational movement of the support tube 41 so that it can only move in a straight line direction.

[0077] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of the nuclear power remote auxiliary fixing device 10, the linear connection structure 43 includes two guide grooves 431 and two guide blocks 432, the two guide grooves 431 are symmetrically arranged on the support tube 41, the two guide blocks 432 are symmetrically arranged on the adjustment seat 21, and the two guide blocks 432 are inserted into the two guide grooves 431 one by one.

[0078] It can be understood that the symmetrical design of the two guide grooves 431 and the two guide blocks 432 provides double guidance, ensuring that the support cylinder 41 can only move in a straight line direction under the drive of the screw member 31 without unnecessary rotation, further improving the accuracy and stability of position adjustment.

[0079] In some embodiments of the nuclear power remote auxiliary fixing device 10 , the circumferential positioning member 22 includes a circumferential positioning bolt, which passes through and is screwed to the base 1 , and the circumferential positioning bolt is detachably supported on the adjustment seat 21 .

[0080] It is understandable that the number of the circumferential positioning bolts can be set to one or more. When the adjustment seat 21 is rotated to a desired angle, the circumferential positioning bolts are tightened to abut against the outer side of the adjustment seat 21, thereby locking the relative position of the adjustment seat 21 and the base 1.

[0081] like Figure 2 and Figure 6 As shown, in some embodiments of the nuclear power remote auxiliary fixing device 10 , the circumferential positioning member 22 includes a circumferential positioning pin, which passes through the base 1 and is detachably supported on the adjustment seat 21 .

[0082] It can be understood that if the circumferential positioning member 22 is configured as a circumferential positioning pin, a plurality of pin holes need to be opened on the adjustment seat 21 accordingly, so that after the circumferential positioning pin passes through the base 1 and is inserted into the pin hole on the adjustment seat 21, the circumferential positioning pin will be abutted against the hole wall of the pin hole, so that the position of the circumferential positioning pin and the pin hole is fixed, and then the relative position and relative angle of the base 1 and the adjustment seat 21 are fixed.

[0083] like Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments of the nuclear power remote auxiliary fixing device 10, a plurality of fixing holes 215 are opened on the circumferential side wall of the adjustment seat 21, and the fixing holes 215 are arranged in a circular array along the circumferential outer wall of the adjustment seat 21 and are evenly spaced. A fixing block 11 is provided on the base 1, and a circumferential positioning member 22 is inserted through the fixing block 11. The circumferential positioning member 22 is detachably inserted into the fixing hole 215.

[0084] It is understandable that the number and position design of the fixing holes 215 can be adjusted according to actual needs to provide sufficient positioning points. The fixing holes 215 are used to cooperate with the circumferential positioning members 22. When the adjustment seat 21 is rotated to a desired angle, the circumferential positioning members 22 can be inserted into the corresponding fixing holes 215, thereby locking the position of the adjustment seat 21 relative to the base 1.

[0085] The fixing block 11 is arranged on the base 1, and its position should be aligned with the fixing hole 215 on the adjustment seat 21, so as to facilitate the insertion of the circumferential positioning member 22. The fixing block 11 can be a convex structure, and a through hole is arranged inside for the circumferential positioning member 22 to pass through.

[0086] In the above-mentioned embodiments, whether threads are provided on the inner wall of the through hole is adjusted according to whether the objects to be connected are connected by threads.

[0087] like Figure 1 As shown, in some embodiments of the nuclear power remote auxiliary fixing device 10, the nuclear power remote auxiliary fixing device 10 further includes a rotation support assembly 5. Figure 3 and Figure 4As shown, the rotation support assembly 5 includes a support block 51 and a rotation groove 52 . The rotation groove 52 is disposed on the adjustment seat 21 . The support block 51 is disposed on the base and inserted into the rotation groove 52 . The support block 51 slides against the groove wall of the rotation groove 52 .

[0088] It can be understood that the rotation support assembly 5 is used to provide additional support and guidance to ensure that the adjustment seat 21 can rotate smoothly and accurately. The support block 51 is arranged on the base 1, usually located on the base 1 or other stable structure. The rotation groove 52 corresponds to the support block 51. The shape and size of the rotation groove 52 are properly designed to ensure that the support block 51 can be inserted and slidably abutted against the groove wall.

[0089] like Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments of the nuclear power remote auxiliary fixing device 10, the connecting member 32 includes a connecting tube 321, a plurality of limiting wings 322, a plurality of limiting bolts 323 and a plurality of connecting blocks 324;

[0090] The screwing member 31 passes through the connecting tube 321, the screwing member 31 is screwed to the connecting tube 321, each limiting wing 322 and each connecting block 324 are arranged on the connecting tube 321, each connecting block 324 corresponds to each limiting wing 322, each limiting bolt 323 passes through each limiting wing 322, and a plurality of thick wall portions 411 are arranged at the end of the supporting tube 41;

[0091] Among them, the connecting tube 321 can be detachably inserted into the end of the supporting tube 41, each limiting wing 322 is correspondingly abutted against one side surface of each thick-walled portion 411, each connecting block 324 is correspondingly abutted against the other side surface of each thick-walled portion 411, and each limiting bolt 323 is screwed to the thick-walled portion 411.

[0092] It can be understood that the screw member 31 is threaded and screwed to the connecting tube 321. The connecting tube 321 transmits the rotational movement of the screw member 31 through the threaded connection, thereby achieving linear movement. The connecting tube 321 can be made of high-strength steel or other wear-resistant materials to ensure durability and reliability for long-term use.

[0093] Each limiting wing 322 is provided on the connecting tube 321 to limit the rotation of the connecting tube 321 in the supporting tube 41 and to provide an additional supporting surface. The number of limiting wings 322 can be adjusted according to actual needs. The limiting wings 322 are usually flat or have a plate-like structure with a certain thickness so as to be supported on the thick wall portion of the supporting tube 41.

[0094] The limiting bolts 323 are used to fix the limiting wings 322 on the thick wall portion of the support tube 41 to prevent the connector 32 from loosening or shifting during operation. The number of the limiting bolts 323 corresponds to the number of the limiting wings 322 to ensure that each limiting wing 322 can be firmly fixed.

[0095] The connecting block 324 is used to abut against the other side of the thick wall portion of the support tube 41, and clamp the support tube 41 together with the limiting wing 322 to ensure a stable connection between the connecting member 32 and the support tube 41. The connecting block 324 is usually a flat or plate-like structure with a certain thickness, so as to abut against the thick wall portion of the support tube 41.

[0096] It should be noted that when the connecting tube 321 is inserted into the end of the supporting tube 41, the limiting wing 322 and the limiting wing 322 are misaligned with the thick-walled portion 411; then, the connecting tube 321 and the supporting tube 41 are rotated relative to each other, so that each thick-walled portion 411 is correspondingly inserted between the limiting wing 322 and the connecting block 324, thereby preventing the thick-walled portion 411 from escaping from the connecting piece 32 and ensuring the stability of the connection.

[0097] like Figures 1 to 3 As shown, in some embodiments of the nuclear power remote auxiliary fixing device 10 , the nuclear power remote auxiliary fixing device 10 further includes a lateral adjustment component 6 and a plurality of longitudinal adjustment components 7 .

[0098] like Figures 4 to 6 As shown, the transverse adjustment assembly 6 includes a transverse fixing block 61, a transverse adjustment bolt 62, a transverse holding block 63, a transverse holding nut 64 and a transverse fixing nut 65.

When the longitudinal adjustment bolt is rotated, it can be extended or retracted into the bottom of the base 1 accordingly.

[0100] It can be understood that the transverse fixing block 61 is arranged on the base 1 for installing the transverse adjustment bolt 62. The transverse fixing block 61 is provided with a threaded hole inside to facilitate the penetration and threading of the transverse adjustment bolt 62.

[0101] The transverse adjustment bolt 62 is passed through and screwed to the transverse fixing block 61, and its end is supported on the transverse supporting block 63. By rotating the transverse adjustment bolt 62, the base 1 can be finely adjusted in the transverse direction.

[0102] The lateral support block 63 is arranged on the base 1 and abuts against the end of the lateral adjustment bolt 62. The lateral support block 63 provides a support point for the lateral adjustment bolt 62.

[0108] It can be understood that after the connecting seat 42 is detachably inserted into the upper in-stack fixing hole 40, the connecting seat 42 is rotated, and the first connecting protrusion 421 is abutted against the second connecting protrusion 50, so that the first connecting protrusion 421 is limited in the upper in-stack fixing hole 40, thereby positioning the relative position of the connecting seat 42 and the upper in-stack component 20, so that the position of the support tube 41 between the upper in-stack component 20 and the auxiliary device 30 is established, thereby ensuring that the support tube 41 can provide stable and reliable support between the upper in-stack component 20 and the auxiliary device 30.

[0109] Furthermore, the number of nuclear power remote auxiliary fixing devices 10 is set to multiple, and multiple nuclear power remote auxiliary fixing devices 10 support and fix the upper in-core component 20 at different positions respectively. The upper in-core component can be supported from different positions respectively, thereby improving the stability of the subsequent disassembly of the parts on the upper in-core component.

[0110] like Figures 3 to 5 As shown, in some embodiments of the nuclear power remote auxiliary fixing device 10, the screwing assembly 3 also includes a lifting ring 33 and a handle 34, the lifting ring 33 is rotatably connected to the screwing member 31, and the handle 34 is slidably penetrated through the screwing member 31.

[0111] The lifting ring 33 is used by lifting equipment to lift the nuclear power remote auxiliary fixing device 10 , and the handle 34 is used by a worker to manually operate to rotate the screw member 31 .

[0112] The implementation of the present invention has the following beneficial effects:

[0113] The present invention relates to a nuclear power remote auxiliary fixing device, which provides stable support for the upper internal component of the pile through a support assembly, thereby solving the problem of easy damage and instability of parts caused by lack of effective support during the disassembly process. The adjustment seat of the adjustment assembly can rotate relative to the base, and the position can be locked by a circumferential positioning member, so that the support cylinder can drive the connecting seat to rotate, so that the connecting seat can be connected and fixed with the connecting position of the upper internal component, and then the support cylinder can form a stable and reliable support between the auxiliary device where the base is set and the upper internal component.

[0114] Furthermore, the screwing assembly can accurately adjust the position of the connecting member by rotating the screwing member, thereby realizing accurate control of the moving distance of the support tube and the connecting seat. This design helps to improve the precision of the operation and reduce the error caused by human factors.

[0115] In addition, the entire device can be connected and installed only by rotating the adjustment seat and the screw at the far end, which can greatly reduce the risk of workers being exposed to dangerous environments.
