Description

Technical Field

[0002] As a neutron moderator, graphite plays an important role in nuclear reactors. In the installation of nuclear reactors, graphite is used as a core element and is assembled layer by layer on the core bottom plate. The core holes of the upper and lower layers of graphite are interconnected to form molten salt channels for injecting molten salt.

[0003] In the process of graphite assembly, due to the large number of graphite components, the matching accuracy (flatness, verticality) between graphite is high, and the graphite assembly has high requirements for the cleanliness of its inner and outer surfaces. Therefore, in order to ensure the quality and efficiency requirements of graphite assembly, a guiding tool that can match the structural form of graphite components is needed to quickly and accurately guide the graphite to be installed in place.

[0004] In the prior art, the guiding tools of the core elements have the following defects:

[0005] 1. The guide rod or guide bar is prone to deflection and deformation, which may cause the rod to be unable to be installed or unable to be pulled out during the assembly process;

[0006] 2. Unable to determine the verticality of the guide rod: For components that require vertical assembly, it is impossible to determine whether the guide rod is vertical, which makes it difficult to ensure assembly accuracy;

[0007] 3. The end of the guide rod is prone to collision with the assembled graphite component and cause damage. The guide rod is assembled in a vertical or horizontal assembly with poor vision, and the position of the guide rod cannot be accurately located. It is often necessary to test the assembly over and over again to put the graphite component into the guide rod. During the test assembly process, the guide rod can easily damage the structural shape of the graphite component.

[0008] 4. Poor assembly cleanliness: Due to the above series of reasons and the material problem of the guide rod, the wear of the graphite components during the assembly process will produce more impurities, which does not meet the cleanliness requirements of the assembly. Utility Model Content

[0073] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0074] Example 1

[0075] This embodiment provides a guide rod 1 for guiding a product to be assembled to improve the positioning accuracy and assembly quality of the product. Specifically, the guided object in this embodiment is a core element 21 to be assembled in a nuclear reactor. The core element 21 is specifically a cylindrical graphite rod. Graphite is a common neutron moderator and plays an important role in nuclear reactors. However, the core element 21 is not limited to graphite. Depending on the application of nuclear reactors or other fields, the core element 21 can also be other materials or products besides graphite.

[0076] like Figure 1 and Figure 2 As shown, the guide rod 1 is a slender rod. When assembling the graphite rod, the guide rod 1 penetrates the core hole of the graphite rod (not shown in the figure) to guide the graphite rod. An axial through hole 2 is provided in the guide rod 1, and at least one signal transmitter 3 and at least one signal receiver 4 are provided at both ends of the through hole 2. The signal transmitter 3 is specifically a laser generator, which is fixed at the bottom of the guide rod 1. The signal receiver 4 includes a wireless sensor 41 and a target 42 on the bottom surface of the wireless sensor 41. The wireless sensor 41 is fixed at the top of the guide rod 1, and the target 42 can receive the laser signal. The laser generator can generate a laser beam 25 and emit the laser beam 25 to the target 42 at the bottom of the wireless sensor 41. The target 42 receives the laser signal and transmits the laser signal to the control system through the wireless sensor 41. The laser hits different positions of the target 42, thus generating different laser signals. Therefore, the control system can obtain the axis offset value of the guide rod 1 based on the comparison between the actual position represented by the received laser signal and the set position, thereby being able to monitor the offset degree of the guide rod 1 in real time so as to make corrections in time and ensure the guiding accuracy of the guide rod 1.

[0077] In other embodiments, according to the size of the guide rod 1, the number of signal transmitters 3 and signal receivers 4 arranged in the axial through hole 2 thereof can be adjusted accordingly as needed, but there must be at least one pair, that is, at least one signal transmitter 3 and at least one signal receiver 4 are used in pairs. The type of signal generated is not limited to laser, and can also be other signal forms that can meet the detection function. The positions of the signal transmitter 3 and the signal receiver 4 in the guide rod 1 can be swapped, and since the signal transmission does not depend on the through hole 2 in the guide rod 1, the guide rod 1 can also be a transparent non-through hole 2 structure, that is, the guide rod 1 can be composed of a middle section of a transparent material and end cavities located at both ends of the middle section, and the signal transmitter 3 and the signal receiver 4 are respectively placed in the two end cavities, and the signal is transmitted in the middle section of the transparent material.

[0078] The guide rod 1 is provided with an axially penetrating through hole 2 to form a hollow structure. Compared with a solid structure, the guide rod 1 of the hollow structure has a higher centroid principal inertia moment, which is more conducive to reducing the deflection of the rod, thereby improving the accuracy of guidance. By arranging a signal transmitter 3 and a signal receiver 4 in the guide rod 1, the actual position of the generated signal is compared with the set position, and the axis offset value of the guide rod 1 can be obtained, thereby determining the verticality of the guide rod 1, so as to facilitate the replacement or adjustment of the guide rod 1, improve the positioning accuracy and guidance efficiency of the guidance, ensure the assembly accuracy of the core element 21; and protect the guided core element 21 from damage, meet the cleanliness requirements of the assembly, and thus be beneficial to the assembly quality of the core element 21.

[0079] Among them, Figure 1 As shown, the guide rod 1 includes a rod body 5, a guide head 7 detachably connected to both ends of the rod body 5, and a quick-release fixing structure 10. In this embodiment, according to the structural form of the core element 21, the guide head 7 adopts a conical design structure, and the bottom end of the guide head 7 can be inserted into the through hole 2 in the rod body 5. When the guide head 7 needs to be replaced, the guide head 7 can also be pulled out from the rod body 5. The guide head 7 can penetrate the core hole of the core element 21 to guide the core element 21 and quickly position it. The guide head 7 is provided with a transition round chamfer 8 at the matching position with the inner wall of the core element 21, that is, at the bottom of the cone of the guide head 7, which can avoid sharp edges from damaging the inner wall of the core element 21 (that is, the molten salt flow channel in the core element 21), which is beneficial to the assembly quality of the core element 21. The quick-release fixing structure 10 is a sleeve that can be sleeved on the bottom outer surface of the rod body 5. The bottom of the sleeve has an external thread structure that can be threadedly connected to the fixed platform to fix the guide rod 1.

[0080] In other embodiments, the structural forms of different assembled core elements 21 are different, and the guide head 7 can be designed according to the cross-sectional form of the inner channel of the assembled core element 21. Regardless of the form, the edges and corners need to be transitioned with rounded corners to avoid damage to the assembled components. For example, a circular cross-section is designed as a conical guide head 7, and a square cross-section is designed as a quadrangular pyramid guide head 7.

[0081] Among them, Figure 3 As shown, the rod body 5 of the guide rod 1 is made of a hard material, and a flexible material 6 is attached to the outer side of the guide rod 1. The guide rod 1 is made of a hard material to enhance the hardness of the guide rod 1, thereby improving the ability of the guide rod 1 to resist deflection and deformation during use. The flexible material 6 is attached to the outer side of the guide rod 1, so that when the guide rod 1 is guiding, its outer side is in flexible contact with the core element 21 to avoid damaging the core element 21.

[0082] In this embodiment, the hard material of the rod body 5 is ceramic, and the flexible material 6 on the outside of the guide rod 1 is carbon fiber material. The guide rod 1 is made of ceramic material, and the high hardness of the ceramic material is more conducive to the ability to resist deflection and deformation. The flexible material 6 on the outside of the guide rod 1 is made of carbon fiber material. On the one hand, the carbon fiber material is a non-metallic material, has good flexibility, and can protect the core element 21 in contact with it; on the other hand, the carbon fiber material has greater strength, which can enhance the toughness of the guide rod 1.

[0083] The guide head 7 is made of a flexible material, and preferably, the guide head 7 is made of the same material as the core element 21. The guide head 7 uses a flexible material 6 to avoid damaging the inner wall of the core element 21. The guide head 7 is made of the same material as the core element 21, and is neither too soft to affect the guiding function nor too hard to damage the inner wall of the core element 21.

[0084] Among them, Figure 4 As shown, the top of the guide rod 1, that is, the top of the guide head 7 is provided with a signal processor 9, and the signal processor 9 is used to cooperate with the positioning monitor 24 provided on the manipulator 23 that clamps the core element 21, so as to position the core element 21 clamped by the manipulator 23 on the guide rod 1. In this embodiment, the signal processor 9 at the top of the guide head 7 is also a laser reflector based on laser signals, and the positioning monitor 24 provided at the corresponding position on the manipulator 23 is a laser emitter. The laser emitter on the manipulator 23 emits a laser beam 25. When the laser beam 25 is captured by the laser reflector on the guide rod 1 and reflected to the laser emitter on the manipulator 23, it indicates that the core hole of the graphite rod clamped by the manipulator 23 is aligned with the guide rod 1, and the position is determined in place, and the guide rod 1 can be inserted for assembly. Therefore, by cooperating with the positioning detector and the signal processor 9, it is possible to determine whether the clamped core element 21 is aligned with the guide rod 1, quickly guide, and ensure accurate positioning. Similarly, the positioning detector and the signal processor 9 can also be detectors and processors of other signal types in other embodiments.

[0085] Example 2

[0086] like Figure 5-Figure 6 As shown, this embodiment provides a guide device 11, which includes a lifting drive 12, a lifting platform 13 and a plurality of guide rods 1 as in Example 1, wherein the plurality of guide rods 1 are arranged in a row and vertically on the lifting platform 13, and the lifting drive 12 is specifically a motor, which is connected to the lifting platform 13, and drives the lifting platform 13 to drive the guide rods 1 to rise and fall in the vertical direction, penetrate into and move to the core element 21 above the guide device 11, and guide the core element 21.

[0087] Above the guide device 11 is the installation platform 17 of the nuclear reactor. The installation platform 17 is installed on the floor 26 of the plant, and the guide device 11 is installed in the foundation pit 27. The installation platform 17 is fixed with a core bottom plate 18, which is fixed to the installation platform 17 by three circumferentially spaced positioning members 171. There are three leveling pads 172 below the core bottom plate 18, which can adjust the core bottom plate 18 to keep it level. There are also three measurement marks 173 arranged circumferentially on the installation platform 17, which can be matched with external position measurement equipment to determine the spatial coordinate information of the core bottom plate 18. The core bottom plate 18 is provided with a plurality of annularly arranged installation holes 19, that is, there are multiple circles of annular installation units 20 from the center to the outside of the core bottom plate 18, and each circle of annular installation units 20 includes a plurality of installation holes 19, which are arranged in a hexagon as a whole. According to the design requirements of the nuclear reactor, core elements 21 such as graphite rods are installed layer by layer on the core bottom plate 18, and the core elements 21 of each layer are installed on each ring of annular mounting units 20 in sequence according to the designed assembly sequence. A row of guide rods 1 on the lifting platform 13 guide the core elements 21 corresponding to a mounting hole 19 of each ring of annular mounting units 20 on the core bottom plate 18. The guide device 11 also includes a guide fixing plate 16, which is connected to the bottom of the mounting platform 17. A control panel 28 is provided on the guide fixing plate 16, and the control panel 28 is electrically connected to the lifting drive motor to control the lifting and lowering of the guide rods 1. During the guiding operation, the guide rods 1 pass through the guide fixing plate 16, the mounting holes 19 on the core bottom plate 18, and the multiple layers of core elements 21 in sequence from the bottom.

[0088] The guide device 11 drives the lifting platform 13 and the guide rod 1 to lift and lower through the lifting driver 12, realizing automatic lifting and guiding, facilitating automatic adjustment of the appropriate position of the guide rod 1 according to the height of the core element 21, and having high guiding efficiency. Moreover, the lifting and lowering is relatively stable, which is beneficial to guiding stability. The position of the core element 21 is accurately determined by the guide rod 1 in a penetrating manner; by adjusting the lifting height of the guide rod 1, the same guide rod 1 can guide the multi-layer core element 21, ensuring that the channel formed by the core hole of the multi-layer core element 21 is not easy to deviate, has good consistency, and has small errors, thereby improving the accuracy and reliability of positioning. By adopting the above-mentioned guide rod 1, it is beneficial to reduce the deflection of the guide rod 1, improve the positioning accuracy and guiding efficiency of the guide, and ensure the assembly accuracy of the core element 21; and protect the guided core element 21 from damage, meet the cleanliness requirements of the assembly, and thus be beneficial to the assembly quality of the core element 21.

[0089] Among them, Figure 7 and Figure 8As shown, the guide rod 1 is detachably connected to the lifting platform 13 through a buckle structure, and the buckle structure includes a male head (not shown in the figure) and a female head 15. The male head is detachably connected to the lifting platform 13, and the bottom end of the guide rod 1 is inserted into the inner hole of the female head 15 and is rotatably connected to the female head 15. The male head and the female head 15 are detachably matched to limit the axial movement of the guide rod 1. Through the buckle structure, the guide rod 1 can be easily removed from the lifting platform 13 for replacement, and the use method is more flexible. The guide rod 1 and the female head 15 are rotatably connected, so that the guide rod 1 can adjust the radial spacing between the guide rod 1 and the female head 15 according to the radial spacing between the guide rod 1 and the guide sleeve, and keep it consistent, which is conducive to the accuracy of the guide. Through the cooperation of the male head and the female head 15, the guide rod 1 is limited to move in the axial direction, and the guide rod 1 is fixed on the lifting platform 13. The fixing method of the guide rod 1 can effectively improve the stability of the pressure rod of the guide rod 1, and at the same time can reduce the requirements for the processing accuracy of the related components of the guide rod 1 on the platform.

[0090] Example 3

[0091] The present embodiment provides an assembly system, which includes a guide device 11 as in Example 2 to guide the core element 21, so the assembly system is also called a core assembly system. The core assembly system realizes automatic lifting and guiding through the above-mentioned guide device 11, thereby improving the guiding efficiency and guiding stability. The above-mentioned guide rod 1 ensures that the channel formed by the core holes of the multi-layer core element 21 is not easy to deviate, has good consistency, and has small errors; reduces the deflection of the guide rod 1, improves the positioning accuracy and guiding efficiency of the guidance, and ensures the assembly accuracy of the core element 21; and protects the guided core element 21 from damage, meets the cleanliness requirements of the assembly, and is beneficial to the assembly quality of the core element 21.

[0092] The core assembly system further comprises a manipulator 23, a signal processor 9 is provided at the top of the guide rod 1, and a positioning monitor 24 is provided on the manipulator 23.

Similar to the first embodiment, in the present embodiment, the signal processor 9 at the top of the guide rod 1 is also a laser reflector based on a laser signal, and the positioning monitor 24 provided at the corresponding position on the manipulator 23 is a laser emitter. The laser emitter on the manipulator 23 emits a laser beam 25. When the laser beam 25 is captured by the laser reflector on the guide rod 1 and reflected to the laser emitter on the manipulator 23, it indicates that the core hole of the graphite rod clamped by the manipulator 23 is aligned with the guide rod 1, and the position is determined in place, and the guide rod 1 can be inserted for assembly. The core assembly system can determine whether the clamped core element 21 is aligned with the guide rod 1, quickly guide, and ensure accurate positioning through the positioning monitor 24 on the manipulator 23 and the signal processor 9 on the guide rod 1.
