DETAILED DESCRIPTION

[0026] In order to better understand the above technical solution, the technical solution of the embodiment of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiment of the present application and the specific features in the embodiment are detailed descriptions of the technical solution of the embodiment of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiment of the present application and the technical features in the embodiment can be combined with each other.

[0027] The embodiment of the present application provides a nuclear grade equipment test device 10, such as Figure 1 and Figure 2 As shown, the nuclear-grade equipment test device 10 includes: a test container 100, a rotating assembly 200, a first support assembly 300 and a second support assembly 400, at least part of the rotating assembly 200 is located in the test container 100, the rotating assembly 200 includes a mounting shell 210 and a rotating member 220, at least part of the rotating member 220 is arranged in the mounting shell 210, the first support assembly 300 abuts against the bottom wall of the mounting shell 210, and the first support assembly 300 is used to provide elastic support in the vertical direction, the second support assembly 400 abuts against the side wall of the mounting shell 210, and the second support assembly 400 is used to provide elastic support in the horizontal direction.

[0028] In this embodiment, the test vessel 100 is used to provide a test environment to simulate the thermal and chemical environment of accident conditions within the containment vessel of a nuclear power plant reactor, and to perform an environmental identification test on the rotating assembly 200 within the test vessel 100. At least part of the rotating part 220 can rotate within the mounting shell 210 to simulate its rotating working state.

[0029] The first support assembly 300 and the second support assembly 400 are respectively in contact with the bottom wall and side wall of the mounting shell 210. When the rotating assembly 200 vibrates, the first support assembly 300 and the second support assembly 400 can respectively generate elastic deformation in the vertical direction and the horizontal direction to absorb the vibration generated by the rotating assembly 200 and provide elastic support for the rotating assembly 200 in the vertical direction and the horizontal direction.

[0030] The elastic support provided by the first support assembly 300 and the second support assembly 400 reduces vibrations generated by the rotating assembly 200 during testing, reduces the impact of vibrations on the rotating assembly 200 during testing, and reduces noise caused by vibrations. It also reduces the impact of thermal deformation of the rotating assembly 200 during testing, resulting in more accurate test results and a quieter test process. Furthermore, the combination of the first support assembly 300 and the second support assembly 400 in different directions provides multi-directional vibration reduction for the rotating assembly 200, enhancing the vibration reduction and noise reduction effects of the rotating assembly 200 and further improving the accuracy of the test results.

[0031] For example, there may be at least two first support assemblies 300 and second support assemblies 400 , wherein the two first support assemblies 300 are located inside and outside the test container 100 , respectively, and the two second support assemblies 400 are located inside the test container 100 and on both sides of the rotating assembly 200 .

[0032] In some embodiments provided in this application, Figure 3 and Figure 4 As shown, the first support assembly 300 includes: a telescopic sleeve 310, a baffle 320 and a first elastic member 330. The telescopic sleeve 310 includes a sleeved sliding cylinder 311 and a fixed cylinder 312. The sliding cylinder 311 is located between the rotating assembly 200 and the fixed cylinder 312. The baffle 320 is arranged on the fixed cylinder 312. The first elastic member 330 is sleeved on the outside of the telescopic sleeve 310. One end of the first elastic member 330 supports the mounting shell 210, and the other end abuts the baffle 320.

[0033] In this embodiment, the telescopic sleeve 310 includes a sleeved sliding sleeve 311 and a fixed sleeve 312. The sliding sleeve 311 can slide axially relative to the fixed sleeve 312, so that the fixed sleeve 312 is slidably connected to the rotating assembly 200 through the sliding sleeve 311. For example, the fixed sleeve 312 is provided on a base, which is used to connect to the mounting surface of the first support assembly 300. The sliding sleeve 311 can be an inner sleeve, and the fixed sleeve 312 can be an outer sleeve, which is sleeved outside the inner sleeve. The fixed sleeve 312 is provided with a baffle 320, which extends radially outward from the fixed sleeve 312.

[0034] The first elastic member 330 is positioned between the mounting housing 210 and the baffle 320. The top end of the first elastic member 330 supports the mounting housing 210, and the bottom end is connected to the baffle 320. The first elastic member 330 is sleeved onto the outside of the telescopic sleeve 310. The telescopic sleeve 310 provides support and guidance for the first elastic member 330, preventing it from excessively bending during expansion and contraction. For example, the first elastic member 330 may be a spring.

[0035] When the rotating assembly 200 vibrates in the vertical direction, the mounting shell 210 drives the sliding cylinder 311 to slide upward or downward, and the distance between the rotating assembly 200 and the baffle 320 changes, causing the first elastic member 330 to produce elastic deformation. The first elastic member 330 absorbs the vibration generated by the rotating assembly 200 in the vertical direction through elastic deformation, and drives the rotating assembly 200 to return to its initial position, so that the rotating assembly 200 can automatically reset.

[0036] Exemplarily, the state of the rotating component 200 before the test is the initial state. When the rotating component 200 is in the initial state, the first elastic member 330 is in a compressed state and produces a slight elastic deformation to generate an appropriate amount of elastic supporting force to offset the gravity of the rotating component 200.

[0037] In some embodiments provided in this application, Figure 3 and Figure 4As shown, the first support assembly 300 also includes: a connecting plate 340 and a first adjusting rod 350, the connecting plate 340 is connected to the mounting shell 210, one end of the first elastic member 330 abuts the connecting plate 340, the top end of the first adjusting rod 350 is movably connected to the connecting plate 340, and the bottom end of the first adjusting rod 350 is connected to the baffle 320.

[0038] In this embodiment, the connecting plate 340 can be a connecting flange, and the connecting plate 340 is connected to the bottom wall of the mounting housing 210 via connecting members, such as bolts. The bottom end of the first adjustment rod 350 is disposed on the baffle 320, and the top end of the first adjustment rod 350 is movable relative to the connecting plate 340, allowing the connecting plate 340 to provide flexible positioning for the top end of the first adjustment rod 350. For example, the connecting plate 340 is provided with a mating hole, which can be a through hole or a blind hole. The top end of the first adjustment rod 350 at least partially extends into the mating hole and is able to move axially within the mating hole.

[0039] The top of the first elastic member 330 supports the mounting housing 210 via the connecting plate 340, expanding the support area of ​​the first elastic member 330 on the rotating assembly 200 and further stabilizing the rotating assembly 200. The connecting plate 340 and the first adjustment rod 350 enhance the structural strength and support strength of the first support assembly 300, thereby improving the supporting effect of the first support assembly 300.

[0040] For example, a stopper 370 can be provided at the top of the first adjustment rod 350. The stopper 370 can be engaged with the connecting plate 340 to limit the extension or retraction position of the first adjustment rod 350. The stopper 370 can be a nut. There can be multiple first adjustment rods 350, which are spaced apart along the circumference of the first elastic member 330.

[0041] In some embodiments provided in this application, Figure 3 and Figure 4 As shown, the first support assembly 300 further includes: a first locking member 360 , which is disposed on the first adjustment rod 350 and can adjust the connection position with the first adjustment rod 350 along the axial direction, and the first locking member 360 abuts against the baffle 320 .

[0042] In this embodiment, the first adjustment rod 350 is connected to the baffle 320 via a first locking member 360. By adjusting the axial position of the first locking member 360 on the first adjustment rod 350, the connection position of the baffle 320 and the first adjustment rod 350 can be adjusted, thereby adjusting the height of the baffle 320, controlling the elastic deformation of the first elastic member 330, and thus controlling the elastic support force generated by the first elastic member 330 in the initial state and the support state. Specifically, the higher the height of the first locking member 360 and the height of the baffle 320, the greater the elastic deformation generated by the first elastic member 330, and the greater the elastic support force provided by the first support assembly 300.

[0043] For example, the first adjusting rod 350 may be a threaded rod, and the first locking member 360 may be a nut or a locking nut.

[0044] In some embodiments provided in this application, Figure 5 and Figure 6 As shown, the second supporting assembly 400 includes: a second elastic member 410 and an adjustment shell 420 . One end of the second elastic member 410 abuts against the mounting shell 210 , and at least a portion of the second elastic member 410 is located in the adjustment shell 420 .

[0045] In this embodiment, one end of the second elastic member 410 abuts the side wall of the mounting housing 210, and the other end connects to the inner wall of the test container 100. The second support assembly 400 is elastically supported by the second elastic member 410. For example, the second elastic member 410 may be a spring. An accommodation space is defined within the adjustment housing 420, and at least a portion of the second elastic member 410 is located within the adjustment housing 420. The adjustment housing 420 provides guidance for the second elastic member 410, preventing it from excessively bending during expansion and contraction.

[0046] In some embodiments provided in this application, Figure 5 As shown, the second support assembly 400 also includes: a second adjusting rod 430 and a rotating shaft 440. The first end of the second adjusting rod 430 extends into the adjusting shell 420 and abuts against the other end of the second elastic member 410. The rotating shaft 440 is connected to the second end of the second adjusting rod 430. When the rotating shaft 440 rotates, it can drive the second adjusting rod 430 to move in the direction of extending into or exiting the adjusting shell 420.

[0047] In this embodiment, the first end of the second adjusting rod 430 extends into the adjusting shell 420 and abuts against the second elastic member 410, and the second end of the second adjusting rod 430 is connected to the inner wall of the test container 100 through the rotating shaft 440. When rotating, the rotating shaft 440 can drive the second adjusting rod 430 to move in the direction of extending into or exiting the adjusting shell 420 to adjust the distance that the second end of the second adjusting rod 430 extends into the adjusting shell 420, control the elastic deformation of the second elastic member 410, and thereby control the elastic supporting force generated by the second elastic member 410 in the initial state and the supporting state.

[0048] Exemplarily, the second adjusting rod 430 is a threaded rod, a threaded hole is provided at the end of the adjusting housing 420 , and the second adjusting rod 430 is connected to the adjusting housing 420 through the threaded hole.

[0049] In some embodiments provided in this application, Figure 5 and Figure 6 As shown, the second support assembly 400 further includes: a second locking member 480 , which is disposed on the second adjustment rod 430 and can adjust the connection position with the second adjustment rod 430 along the axial direction, and the second locking member 480 abuts against the adjustment shell 420 .

[0050] In this embodiment, the second adjustment rod 430 is connected to the adjustment housing 420 via a second locking member 480. By adjusting the axial position of the second locking member 480 on the second adjustment rod 430, the distance that the second end of the second adjustment rod 430 extends into the adjustment housing 420 can be adjusted, thereby controlling the elastic deformation of the second elastic member 410 and, in turn, the elastic supporting force generated by the second elastic member 410 in the initial state and the supporting state. Specifically, the deeper the second end of the second adjustment rod 430 extends, the greater the elastic deformation generated by the second elastic member 410, and the greater the elastic supporting force provided by the second support assembly 400.

[0051] For example, a through hole is provided at the end of the adjustment housing 420 , and the second locking member 480 may be a nut or a locking nut.

[0052] In some embodiments provided in this application, Figure 5 As shown, the second support assembly 400 also includes: a mounting cylinder 450 and an adjustment block 460. The mounting cylinder 450 is connected to the inner wall of the test container 100. At least part of the rotating shaft 440 extends into the mounting cylinder 450. The adjustment block 460 is located in the mounting cylinder 450. One end surface of the adjustment block 460 is in contact with the inner wall of the test container 100, and the other end surface is flat and connected to the rotating shaft 440.

[0053] In this embodiment, an adjustment block 460 is disposed within the mounting tube 450. The bottom surfaces of the mounting tube 450 and the adjustment block 460 conform to the shape of the inner wall of the test container 100 and fit in contact with each other. The rotating shaft 440 is connected to the inner wall of the test container 100 via the mounting tube 450 and the adjustment block 460. The connection surface between the adjustment block 460 and the rotating shaft 440 is a flat surface. The adjustment block 460 converts the contact surface of the rotating shaft 440 from the curved wall surface of the test container 100 to a flat end surface of the adjustment block 460, allowing the rotating shaft 440 to contact the flat surface during rotation. This allows the rotating shaft 440 to rotate smoothly, preventing the curved surface of the test container 100 from hindering the rotation of the rotating shaft 440.

[0054] In some embodiments provided in this application, Figure 5 As shown, the diameter of the rotating shaft 440 is greater than the diameter of the second adjusting rod 430 , and the length of the rotating shaft 440 is greater than the length of the second adjusting rod 430 .

[0055] In this embodiment, the rotating shaft 440 is thicker and longer than the second adjustment rod 430. For example, the length of the rotating shaft 440 is 4 to 8 times the length of the second adjustment rod 430. This provides the rotating shaft 440 with greater strength, thereby improving the structural strength of the second support assembly 400 and ensuring that the second support assembly 400 can meet the support requirements.

[0056] In some embodiments provided in this application, Figure 5 As shown, the second supporting assembly 400 further includes: an operating member 470 and / or a cushion block 490 . The operating member 470 is disposed on the rotating shaft 440 , and the cushion block 490 is disposed on the end of the second elastic member 410 .

[0057] In this embodiment, an operating member 470 is provided on the rotating shaft 440. When adjusting the second support assembly 400, the operator can hold the operating member 470, which improves the convenience and accuracy of controlling the rotating shaft 440. For example, the operating member 470 can be a handle or an operating lever.

[0058] A pad 490 is provided at the end of the second elastic member 410, which increases the contact area between the second elastic member 410 and the mounting shell 210 and the second adjusting rod 430, expands the application range of the elastic force, and enables the elastic force to be more evenly applied to the mounting shell 210 and the second adjusting rod 430, thereby improving the stability of the second support assembly 400 during elastic movement.

[0059] In a specific embodiment, the rotating component 200 is placed on the vertical elastic support (i.e., the first support component 300), the vertical elastic support is placed in the test container 100 or on the horizontal support platform, and at the same time, one end of the horizontal elastic support (i.e., the second support component 400) is horizontally connected to the test container 100, and the other end of the horizontal elastic support is connected to the rotating component 200. Finally, the matching connection interfaces of the rotating component 200, the test container 100, the horizontal elastic support, and the vertical elastic support are tightened and locked, thereby achieving the purpose of shock-absorbing support of the rotating component 200 under environmental testing.

[0060] Its main features include operability and ease of installation, requiring only welding and simple machining. It is economical, with component materials readily available and inexpensive. It is also feasible, with the device able to withstand the harsh conditions of LOCA environments without failure, while also providing vibration damping and noise reduction for the rotating mechanism.
