Description

Technical Field

[0001] This invention relates to the field of nuclear reactors, and more specifically to a deep-hole measurement fixture for microtube thermal reactors. Background Technology

[0002] Microtube-cooled reactors (MTBRs) are a new type of reactor that utilizes heat pipes to cool its core. They are primarily composed of a core, an energy conversion system, and a shielding and heat dissipation system, and are potential candidates for decentralized electricity markets. The reactor employs heat pipes, a monolithic core, and a highly efficient energy conversion system, significantly simplifying main piping, circulation pumps, and auxiliary equipment. This results in lower costs, a more compact system, and, compared to commercial nuclear power plants, the ability to be manufactured and transported in factories, thus ensuring safety during launch or transport accidents.

[0003] The design process of microtube thermal reactors requires the fabrication of ultra-deep holes exceeding 1.5m in the reactor core, with relatively small apertures. Traditional measuring devices cannot meet the high-precision measurement requirements. Summary of the Invention

[0004] The present invention was made to solve the above-mentioned technical problems, and its purpose is to provide a deep hole measurement fixture for microtube thermal stacks, which can realize high-precision measurement of deep holes.

[0005] In a first aspect, this application discloses a deep-hole measurement fixture for a microtube thermal reactor, comprising: a base assembly having a mounting cavity and an observation port communicating with the mounting cavity, wherein the mounting cavity, the observation port, and the reactor core on the base assembly are at progressively increasing heights, and the observation port corresponds to the area on the base assembly used for mounting the reactor core; a support assembly mounted on the base assembly; a first measuring assembly mounted on the support assembly, wherein the first measuring assembly is positioned at a height higher than the reactor core placed on the base assembly, the first measuring assembly including a laser sensor and a first image acquisition module; and a second measuring assembly disposed in the mounting cavity, the second measuring assembly including a reflective target sphere and a second image acquisition module; wherein the first image acquisition module is used to acquire image information of the hole to be measured at the top of the reactor core; the second image acquisition module is used to acquire image information of the hole to be measured at the bottom of the reactor core; at least one of the first measuring assembly and the second measuring assembly can adjust its position so that the laser sensor corresponds to the reflective target sphere along the height direction. Compared to existing technologies that require manual measurement of multiple cross-sections of the hole to be measured using methods such as dial gauges to obtain relevant parameters, this application uses an image acquisition device to acquire images of the upper and lower end faces of the hole to be measured at once, thereby obtaining the required measurement parameters. This makes the measurement more convenient and more accurate.

[0006] Optionally, the measuring fixture further includes: a first adjustment mechanism disposed on the base assembly and connected to the support assembly, the first adjustment mechanism being capable of driving the support assembly to move along the length direction of the fixture; and a second adjustment mechanism installed on the support assembly and connected to the first measuring assembly, the first adjustment mechanism being capable of driving the first measuring assembly to move along the width direction of the fixture.

[0007] Optionally, the first adjustment mechanism is located in the mounting cavity, and the height increases at the locations of the first adjustment mechanism and the second measuring component.

[0008] Optionally, the base assembly includes a base plate and a support, the base plate being used to place the reactor core, and an observation port being located on the base plate; an installation cavity is formed between the base plate and the support; the first adjustment mechanism and the second measuring assembly are both connected to the support.

[0009] Optionally, the base assembly also includes a chuck for clamping the reactor core. The chuck is located on the side of the base plate away from the support. The chuck has a through hole that corresponds to the observation port along the height direction. The reactor core can pass through the through hole and be placed on the base plate to correspond to the observation port.

[0010] Optionally, the vias are configured to restrict the rotational degree of freedom of the core about its own axis, which is along the height direction.

[0011] Optionally, the support assembly includes a crossbeam and a support beam, the crossbeam being disposed opposite to the base assembly along the height direction, and the support beam being connected to the crossbeam and the second adjustment mechanism respectively.

[0012] Optionally, the first measuring component further includes: a measuring fixture mounting bracket installed to the support assembly; and a third adjustment mechanism installed to the measuring fixture mounting bracket, wherein the laser sensor and the first image acquisition module are both installed to the third adjustment mechanism, and the third adjustment mechanism is used to drive the laser sensor and the first image acquisition module to move along the height direction.

[0013] Optionally, the second measuring component further includes a fourth adjustment mechanism and a fifth adjustment mechanism connected to each other. The fourth adjustment mechanism is installed on the base assembly, and the fifth adjustment mechanism is located in the fourth adjustment mechanism. The reflective target ball and the second image acquisition module are both located in the fifth adjustment mechanism. The fourth adjustment mechanism is used to drive the reflective target ball and the second image acquisition module to move along the length direction of the fixture with the fifth adjustment mechanism. The fifth adjustment mechanism is used to drive the reflective target ball and the second image acquisition module to move along the width direction of the fixture.

[0014] The beneficial effects of this invention are as follows: Compared to existing technologies that require manual measurement of multiple cross-sections of the hole to be measured using methods such as dial gauges to obtain relevant parameters, this application uses an image acquisition device to acquire images of the upper and lower end faces of the hole to be measured at once, thereby obtaining the required measurement parameters. This makes the measurement more convenient and more accurate. Attached Figure Description

In addition, certain features, structures, or characteristics in one or more embodiments of the application can be appropriately combined.

[0022] The following is combined Figures 1-6This application discloses a deep-hole measurement fixture for a microtube thermal reactor, wherein the microtube thermal reactor, also known as a micro heat pipe cooled reactor, is a novel micro reactor that utilizes heat pipes to cool its core. During the design process of the microtube thermal reactor, it is necessary to machine an ultra-deep hole exceeding 1.5m into the core 10. This ultra-deep hole is... Figure 1 The test hole 11 extends along the height direction of the core 10 and is evenly distributed on the core 10. The diameter of the test hole 11 is relatively small compared with the hole depth. Generally, the hole depth exceeds 1.5m and the hole diameter ratio exceeds 70. The tooling of this application can realize the effective measurement of the test hole 11. The details are as follows.

[0023] The deep hole measurement fixture of this embodiment includes a base assembly 100, a support assembly 200, a first measurement assembly 300, and a second measurement assembly 400. The base assembly 100 is used to place the core 10, and the height direction of the placed core 10 is consistent with the height direction Z of the fixture.

[0024] The base assembly 100 is provided with a mounting cavity and an observation port 102 communicating with the mounting cavity. The mounting cavity, the observation port 102, and the location of the core 10 on the base assembly 100 increase in height along the Z direction, and the observation port 102 corresponds to the area on the base assembly 100 used for mounting the core 10. In this embodiment, the observation port 102 is circular, and the core 10 is a microtube thermal reactor core. The outer contour of the cross-section of the core 10 can be... Figure 1 and Figure 2 The hexagon shown has several deep holes extending along the height direction Z inside the core 10, which are the test holes 11. When the core 10 is placed on the base assembly 100, the intersection of the two sides of the core 10 is in contact with the solid part of the base assembly 100. The group of holes formed by the several test holes 11 is fully exposed at the observation port 102 and is not blocked by the base assembly 100.

[0025] The support assembly 200 is mounted on the base assembly 100. The first measuring assembly 300 is mounted on the support assembly 200, and the height of the first measuring assembly 300 is higher than that of the core 10 placed on the base assembly 100. The first measuring assembly 300 includes a laser sensor 301 and a first image acquisition module 302.

[0026] The second measurement component 400 is disposed in the mounting cavity, and includes a reflective target sphere 401 and a second image acquisition module 402. The first image acquisition module 402 is used to acquire image information of the hole to be tested 11 at the top of the reactor core 10; the second image acquisition module 402 is used to acquire image information of the hole to be tested 11 at the bottom of the reactor core 10; at least one of the first measurement component 300 and the second measurement component 400 can adjust its position so that the laser sensor 301 corresponds to the reflective target sphere 401 along the height direction Z. During measurement, the laser emitted by the laser sensor 301 is aligned with the reflective target sphere 401 to complete the coaxial calibration of the upper and lower measurement references, so as to establish a reference coordinate system. Then, the upper and lower end face images of the hole to be measured 11 are acquired by two image acquisition modules respectively. The aperture of the upper and lower end face of the hole to be measured 11 and the center coordinates of the upper and lower end face of the hole to be measured in the reference coordinate system can be obtained by image recognition. Thus, the aperture range, straightness and other parameters of the hole to be measured 11 can be evaluated. It can be seen that compared with the existing technology, which requires manual measurement of multiple cross sections of the hole to be measured 11 by means of dial gauges to obtain relevant parameters, this application can acquire the images of the upper and lower end face of the hole to be measured 11 at one time through the image acquisition device, and then obtain the required measurement parameters. This measurement is more convenient and has higher measurement accuracy.

[0027] Furthermore, the first image acquisition module 302 and the second image acquisition module 402 can be cameras, scanners, etc. At the same time, in order to avoid obstruction and interference from other components, the first image acquisition module 302 and the second image acquisition module 402 can be set to one or more as needed, which will not be described in detail here.

[0028] Furthermore, the measuring fixture also includes a first adjustment mechanism 500 and a second adjustment mechanism 600. The first adjustment mechanism 500 is disposed on the base assembly 100 and connected to the bottom of the support assembly 200. The first adjustment mechanism 500 can drive the support assembly 200 to move along the length direction X of the fixture, specifically as follows... Figure 5 As shown. The second adjustment mechanism 600 is mounted on the top of the support assembly 200 and connected to the first measuring assembly 300. The second adjustment mechanism 600 can drive the first measuring assembly 300 to move along the width direction Y. Through the cooperation of the two adjustment mechanisms, the first measuring assembly 300 can be adjusted to any position on the XY plane, so that the laser emitted by the laser sensor 301 can be aligned with the reflective target sphere 401 to complete the coaxial calibration of the upper and lower measuring references.

[0029] As an optional implementation, the first adjustment mechanism 500 is... Figure 5The lead screw mechanism shown includes a first motor 501 and a first lead screw 502, both mounted to the base assembly 100; a first adjusting seat 503 that engages with the first lead screw 502 in a helical transmission; and a paired first guide rail 504. The bottom of the support assembly 200 is connected to the first adjusting seat 503, which is fitted onto the first guide rail 504 and engages with it in a guiding relationship along the length direction X. The first motor 501 can drive the first lead screw 502 to rotate, so that the support assembly 200 moves in translational motion along the length direction X with the first adjusting seat 503. This structure has high transmission accuracy and stable operation, ensuring that the adjustment accuracy in the length direction X reaches the 0.01 mm level, meeting the high-precision measurement requirements of deep holes in microtube thermal stacks.

[0030] Furthermore, such as Figure 5 As shown, the first adjustment mechanism 500 is located in the mounting cavity, and the height of the positions of the first adjustment mechanism 500 and the second measuring component 400 increases along the height direction Z. This layout can avoid interference between the movement paths of the first adjustment mechanism 500 and the second measuring component 400, while making full use of the internal space of the mounting cavity and reducing the overall volume of the tooling.

[0031] As an optional implementation, such as Figure 5 As shown, the base assembly 100 includes a base plate 110 and a support 120: the base plate 110 is used to place the reactor core 10, and the observation port 102 is disposed on the base plate 110; the base plate 110 and the support 120 form the mounting cavity; the first adjustment mechanism 500 and the second measuring component 400 are both connected to the support 120. This base assembly 100 structure ensures the stability of the support structure, thereby improving measurement stability.

[0032] Furthermore, such as Figure 5 and Figure 6 As shown, the base assembly 100 further includes a chuck 130 for clamping the reactor core 10. The chuck 130 is located on the side of the base plate 110 opposite to the support 120. The chuck 130 has a through hole 131, which corresponds to the observation port 102 along the height direction Z. The reactor core 10 can pass through the through hole 131 and be placed on the base plate 110 to correspond to the observation port 102, thereby facilitating the second image acquisition module 402 to acquire image information of the lower end face of the reactor core 10 through the observation port 102. The chuck 130 can be a three-jaw chuck, which, through the jaws of the chuck 130, enables automatic centering of the reactor core 10 and maintains its positional stability.

[0033] Furthermore, the via 131 is configured to restrict the rotational degree of freedom of the core 10 about its own axis, the axis of the core 10 being along the height direction Z; for example... Figure 6 As shown, in this embodiment, the through hole 131 is a regular hexagonal hole, which is adapted to the shape of the hexagonal outer peripheral surface of the core 10, so as to realize the quick positioning and clamping of the core 10 without the need for additional adjustment of the circumferential position.

[0034] As an optional implementation, the support assembly 200 includes a crossbeam 211 and a support beam 212: the crossbeam 211 is disposed opposite to the base assembly 100 along the height direction Z; the top of the support beam 212 is connected to the crossbeam 211 and the second adjustment mechanism 600 respectively; and the bottom of the support beam 212 is connected to the first adjustment seat 503 of the first adjustment mechanism 500, specifically as follows... Figure 4 and Figure 5 As shown, this is to make the device structure layout reasonable.

[0035] Optionally, such as Figure 4 and Figure 5 As shown, the support beams 212 are paired along the width direction Y, and the second adjustment seat 603 of the second adjustment mechanism 600 is located between the paired support beams 212. The support beams 212 and the base assembly 100 are offset along the height direction Z to connect to the first adjustment seat 503 of the first adjustment mechanism 500. The symmetrical support structure of the support beams 212 can improve the structural rigidity of the bracket assembly 200, prevent the first adjustment mechanism 500 and the first measuring component 300 from shaking during movement, ensure measurement accuracy, and limit the movement of the second adjustment mechanism 600 to prevent the first measuring component 300 from moving excessively.

[0036] Furthermore, such as Figure 4 As shown, the second adjustment mechanism 600 is a lead screw mechanism, including a second motor 601, a second lead screw 602, a second guide rail 604, and a second adjustment seat 603. The two ends of the second lead screw 602 are rotatably mounted on support beams 212. The second motor 601 is installed on one of the support beams 212 and connected to the second lead screw 602. The second guide rails 604 are paired along the height direction Z, with the second lead screw 602 located between the paired guide rails 604. The second adjustment seat 603 is helically driven and engaged with the second lead screw 602 along the width direction Y, and also guides the second guide rails 604 along the width direction Y. The first measuring component 300 is installed on the second adjustment seat 603. Thus, the second motor 601 can drive the second adjustment seat 603 to move via the second lead screw 602, thereby adjusting the position of the first measuring component 300 along the width direction Y. Furthermore, this structure has high transmission accuracy and stable operation, ensuring an adjustment accuracy of 0.01 mm in the width direction Y, meeting the high-precision measurement requirements of deep holes in microtube thermal stacks.

[0037] like Figure 3As shown, as an optional embodiment, the first measuring component 300 further includes a measuring tool mounting bracket 310 mounted to the support component 200 and a third adjustment mechanism 320 mounted to the measuring tool mounting bracket 310. The laser sensor 301 and the first image acquisition module 302 are both mounted to the third adjustment mechanism 320. The third adjustment mechanism 320 is used to drive the laser sensor 301 and the first image acquisition module 302 to move along the height direction Z, thereby adapting to the core 10 at different heights. It also ensures the field of view of the first image acquisition module 302 during acquisition by adjusting its position along the height direction Z, and adjusts the focusing distance of the first image acquisition module 302 to obtain a clear hole end face image.

[0038] Specifically, the third adjustment mechanism 320 includes a third motor 321, a third lead screw 322, a third guide rail 324, and a third adjustment seat 323. The two ends of the third lead screw 322 are rotatably mounted on the measuring tool mounting frame 310. The third motor 321 is mounted on the measuring tool mounting frame 310 and connected to the third lead screw 322. The third guide rails 324 are paired along the width direction Y, and the third lead screw 322 is located between the paired third guide rails 324. The third adjustment seat 323 is helically driven and engaged with the third lead screw 322 along the height direction Z, and is also guided and engaged with the third guide rails 324 along the height direction Z. The laser sensor 301 and the first image acquisition module 302 are both mounted on the third adjustment seat 323. In this way, the third motor 321 can drive the third adjustment seat 323 to move through the third lead screw 322, thereby adjusting the position of the laser sensor 301 and the first image acquisition module 302 along the height direction Z. Furthermore, this structure boasts high transmission precision and stable operation, ensuring an adjustment accuracy of 0.01 mm in the height direction Z, thus meeting the high-precision measurement requirements for deep holes in microtube thermal stacks.

[0039] As an optional implementation, the second measurement component 400 further includes a fourth adjustment mechanism 410 and a fifth adjustment mechanism 420 connected to each other. The fourth adjustment mechanism 410 is mounted to the base assembly 100, and the fifth adjustment mechanism 420 is located on the fourth adjustment mechanism 410. The reflective target ball 401 and the second image acquisition module 402 are both located on the fifth adjustment mechanism 420. The fourth adjustment mechanism 410 drives the reflective target ball 401 and the second image acquisition module 402 to move along the length direction X with the fifth adjustment mechanism 420, and the fifth adjustment mechanism 420 drives the reflective target ball 401 and the second image acquisition module 402 to move along the width direction Y. This achieves position adjustment of the reflective target ball 401 in the XY plane. By coordinating with the position adjustment of the laser sensor 301 in the XY plane, the emitted laser can avoid the aperture wall, adapting to the measurement of cores 10 of different specifications.

[0040] Specifically, the fourth adjustment mechanism 410 is a lead screw mechanism and includes a fourth motor 411, a fourth lead screw 412, a fourth guide rail 414, and a fourth adjustment seat 413; the fifth adjustment mechanism 420 is a lead screw mechanism and includes a fifth motor 421, a fifth lead screw 422, and a fifth adjustment seat 423.

[0041] The fourth lead screw 412 is rotatably mounted to the support 120. The fourth motor 411 is mounted to the support 120 and connected to the fourth lead screw 412. The fourth guide rail 414 is paired with and mounted to the support 120. The fourth adjusting seat 413 is helically driven along the length direction X, engaging with the fourth lead screw 412, and is guided by the fourth guide rail 414. The fifth motor 421 is mounted to the fourth adjusting seat 413. The fifth lead screw 422 is connected to the fifth motor 421. The fifth adjusting seat 423 is helically driven along the width direction Y, engaging with the fifth lead screw 422, and is slidably connected to the fourth adjusting seat 413 along the width direction Y. The fourth motor 411 drives the fourth adjusting seat 413 to move along the length direction X, and the fifth motor 421 drives the fifth adjusting seat 423 to move along the width direction Y, thereby realizing the position adjustment of the reflective target ball 401 in the XY plane. The lead screw adjustment has high precision and strong stability.

Any variations and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
