Description

Technical Field

[0001] This invention relates to the field of nuclear power plant construction engineering technology, and in particular to a steam generator compartment structure. Background Technology

[0002] A steam generator is a device used in nuclear power plant reactors to produce the steam required by the plant. A steam generator compartment structure needs to be installed within the nuclear power plant to house the steam generator. During subsequent use, to protect the steam generator, a scaffolding structure needs to be erected in the gap between the steam generator and the steam generator compartment structure. This allows maintenance personnel to stand on the scaffolding to perform maintenance. However, erecting the scaffolding is time-consuming, requires a large amount of labor, and has low construction efficiency. Summary of the Invention

[0003] The main objective of this invention is to provide a steam generator compartment structure that solves the technical problem in the prior art where a frame needs to be erected in the gap between the steam generator and the steam generator compartment structure for maintenance personnel to stand and maintain the steam generator. However, the erection of the frame is time-consuming, requires a large amount of labor, and has low construction efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] In a first aspect, the present invention provides a steam generator compartment structure, the steam generator compartment structure comprising:

[0006] The enclosure module includes an arc-shaped wall and two planar walls, both of which extend vertically. The two planar walls are respectively connected to both ends of the arc-shaped wall and enclose a cavity for accommodating the steam generator. The cavity extends vertically.

[0007] An operating platform module is disposed within the accommodating cavity. The operating platform is connected to the arc-shaped wall and the two planar walls. The operating platform module forms a passage cavity, through which the steam generator, housed within the accommodating cavity, passes.

[0008] Optionally, the operating platform module includes multiple operating platforms, which are longitudinally spaced within the accommodating cavity. Each operating platform is connected to the arc-shaped wall and the two planar walls, and each operating platform forms a through opening. The through openings of the multiple operating platforms are sequentially connected vertically to form the passage cavity.

[0009] Optionally, the operating platform includes an arc-shaped segment and two strip segments. The arc-shaped segment is connected to the side of the arc-shaped wall facing the receiving cavity, and the two strip segments are respectively connected to the sides of the two planar walls near the receiving cavity. The two strip segments are respectively connected to the two ends of the arc-shaped segment, forming a U-shaped operating platform and enclosing the through opening.

[0010] Optionally, an additional operating platform is also installed at the through-hole of each of the operating platforms, with the two ends of the additional operating platform respectively connected to the ends of the two strip segments away from the arc segment.

[0011] Optionally, the two ends of the additional operating platform are detachably connected to the ends of the corresponding two strip segments away from the arc segment.

[0012] Optionally, in each of the operating platforms, two first reinforcing structures are connected between the arc segment and the two strip segments, and two second reinforcing structures are connected between the additional operating platform and its corresponding two strip segments.

[0013] Optionally, the first reinforcing structure includes a plurality of first reinforcing ribs, with both ends of each first reinforcing rib connected to the arc-shaped end and its corresponding strip segment; the second reinforcing structure includes a plurality of second reinforcing ribs, with both ends of each first reinforcing rib connected to the additional operating platform and its corresponding strip segment.

[0014] Optionally, the arc-shaped segment has a plurality of first connection positions on the side facing the arc-shaped wall, the plurality of first connection positions being spaced apart along the extension direction of the arc-shaped segment, and the arc-shaped segment being connected to the arc-shaped wall through the plurality of first connection positions; the strip segment has a plurality of second connection positions on the side facing the flat wall, the plurality of second connection positions being spaced apart along the extension direction of the strip segment, and the strip segment being connected to the flat wall through the plurality of second connection positions.

[0015] Optionally, a ladder may be connected between any two adjacent operating platforms.

[0016] Optionally, each of the operating platforms is equipped with railings.

[0017] This invention proposes a steam generator compartment structure. It comprises an arc-shaped wall and two flat walls, with the two flat walls connected to the ends of the arc-shaped wall to form a cavity. An operating platform module is installed within this cavity, connecting to the arc-shaped wall and the flat walls to form the steam generator compartment structure. This steam generator compartment structure is installed at a predetermined location in the nuclear power plant building. After the steam generator compartment structure is installed, the steam generator is installed within the cavity. Because the steam generator passes through the passageway of the operating platform module within the cavity, maintenance personnel can perform maintenance simply by standing on the operating platform. Maintenance can be achieved solely through the operating platform module integrated into the compartment structure, eliminating the need for additional scaffolding between the compartment structure and the steam generator. This eliminates the time and manpower required for scaffolding construction, resulting in high construction efficiency. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0024] It should be noted that in the embodiments of the present invention, all directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0025] In this invention, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or system. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or system that includes that element. Furthermore, the meaning of "and / or" throughout the text includes three parallel options; for example, "A and / or B" includes option A, option B, or options where both A and B are satisfied.

[0026] In this invention, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements.

[0027] In this invention, if there are descriptions involving "first," "second," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0028] In this invention, the use of suffixes such as "module," "component," "part," "unit," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" can be used interchangeably.

[0029] For those skilled in the art, the specific meanings of the above terms in this invention can be understood according to the specific circumstances. Furthermore, the technical solutions of the various embodiments can be combined with each other; however, this is based on the premise that those skilled in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0030] The inventive concept of the present invention will be further explained below with reference to some specific embodiments.

[0031] This invention proposes a steam generator compartment structure 100, which includes an enclosure module 10 and an operating platform module 20. The enclosure module 10 includes an arc-shaped wall 11 and two planar walls 12, both of which extend vertically. The two planar walls 12 are respectively connected to the two ends of the arc-shaped wall 11 and enclose a cavity 13 for accommodating the steam generator. The cavity 13 extends vertically. The operating platform module 20 is disposed within the cavity 13. The operating platform 21 is connected to the arc-shaped wall 11 and the two planar walls 12. The operating platform module 20 forms a passage cavity 22, through which the steam generator, housed in the cavity 13, passes.

[0032] Specifically, as shown in the figure, an arc-shaped wall 11 and two flat walls 12 are provided. The two flat walls 12 are connected to both ends of the arc-shaped wall 11 to form a cavity 13. An operating platform module 20 is installed in the cavity 13. The operating platform module 20 is connected to the arc-shaped wall 11 and the flat walls 12 to form a steam generator compartment structure 100. The steam generator compartment structure 100 is installed in a predetermined position in the nuclear power plant building. After the steam generator compartment structure 100 is installed, the steam generator is installed in the cavity 13. Since the steam generator passes through the passage 22 of the operating platform module 20 and is located in the cavity 13, maintenance personnel can maintain the steam generator by standing on the operating platform module 20. Maintenance of the steam generator can be achieved solely through the operating platform module 20 integrated into the compartment structure, eliminating the need to erect additional scaffolding between the steam generator compartment structure 100 and the steam generator. This eliminates the time and manpower consumed by erecting scaffolding, resulting in high construction efficiency.

[0033] In one embodiment, the operating platform module 20 includes multiple operating platforms 21, which are longitudinally spaced within the accommodating cavity 13. Each operating platform 21 is connected to the arc-shaped wall 11 and two planar walls 12. Each operating platform 21 forms a through opening 212, and the through openings 212 of the multiple operating platforms 21 are sequentially connected vertically to form a passage cavity 22.

[0034] Specifically, as shown in the figure, the vertical direction is the up-down direction. Multiple operating platforms 21 are arranged sequentially and spaced apart in the accommodating cavity 13 along the up-down direction. By using operating platforms 21 at different heights, the steam generator can be maintained at different heights, which improves the maintenance effect of the steam generator and has high maintenance efficiency.

[0035] In one embodiment, the operating platform 21 includes an arc-shaped segment 213 and two strip segments 214. The arc-shaped segment 213 is connected to the side of the arc-shaped wall 11 facing the receiving cavity 13, and the two strip segments 214 are respectively connected to the side of the two planar walls 12 near the receiving cavity 13. The two strip segments 214 are respectively connected to the two ends of the arc-shaped segment 213, forming a U-shaped operating platform 21, and enclosing a through opening 212.

[0036] Specifically, as shown in the figure, the operating platform 21 formed by the arc segment 213 and the two strip segments 214 is U-shaped. When the steam generator is installed, it can be moved horizontally from the opening of the U-shaped operating platform 21 into the through opening 212 and placed in the receiving cavity 13. There is no need to hoist the steam generator from a high place and pass it through the top of the steam generator compartment structure 100 into the receiving cavity 13. The installation is convenient and relatively safe.

[0037] In one embodiment, an additional operating platform 70 is also installed at the through-hole 212 of each operating platform 21, and the two ends of the additional operating platform 70 are respectively connected to the ends of the two strip segments 214 away from the arc segment 213.

[0038] Specifically, as shown in the figure, after the steam generator compartment structure 100 is installed, an additional operating platform 70 is installed at the opening of the U-shaped operating platform 21. The additional operating platform 70 and the U-shaped operating platform 21 together form a ring-shaped operating platform 21 surrounding the steam generator. The ring-shaped operating platform 21 can provide multi-directional and more comprehensive maintenance for the steam generator, improving the maintenance effect and efficiency of the steam generator.

[0039] In one embodiment, the two ends of the auxiliary operating platform 70 are detachably connected to the ends of the corresponding two strip segments 214 away from the arc segment 213. The detachable auxiliary operating platform 70 facilitates the replacement of the steam generator. When the steam generator needs to be replaced, the auxiliary operating platform 70 only needs to be removed, and the steam generator can be replaced through the opening of the U-shaped operating platform 21. After the replacement is completed, the U-shaped operating platform 21 only needs to be reinstalled for continued use. The operation is convenient and efficient.

[0040] In one embodiment, in each operating platform 21, two first reinforcing structures 30 are respectively connected between the arc segment 213 and the two strip segments 214, and two second reinforcing structures 40 are respectively connected between the additional operating platform 70 and its corresponding two strip segments 214.

[0041] Specifically, as shown in the figure, a first reinforcing structure 30 is connected between each strip segment 214 and its corresponding arc segment 213, and a second reinforcing structure 40 is connected between each strip segment 214 and its corresponding additional operating platform 70. This can improve the structural strength of the operating platform 21 itself, as well as the firmness of the connection between the additional operating platform 70 and the operating platform 21, making it safe and reliable.

[0042] In one embodiment, the first reinforcing structure 30 includes a plurality of first reinforcing ribs, with both ends of each first reinforcing rib connected to the arc-shaped end and its corresponding strip segment 214, respectively; the second reinforcing structure 40 includes a plurality of second reinforcing ribs, with both ends of each first reinforcing rib connected to the additional operating platform 70 and its corresponding strip segment 214, respectively.

[0043] Specifically, connecting multiple first reinforcing ribs between each strip segment 214 and its corresponding arc segment 213 can further improve the strength of the connection between the strip segment 214 and its corresponding arc segment 213, so that the operating platform 21 itself has higher structural strength. Connecting multiple second reinforcing ribs between each strip segment 214 and its corresponding additional operating platform 70 can make the connection between the additional operating platform 70 and the operating platform 21 more secure and stronger.

[0044] In one embodiment, a plurality of first connection positions 2131 are formed on the side of the arc segment 213 facing the arc wall 11. The plurality of first connection positions 2131 are spaced apart along the extension direction of the arc segment 213, and the arc segment 213 is connected to the arc wall 11 through the plurality of first connection positions 2131. A plurality of second connection positions 2141 are formed on the side of the strip segment 214 facing the planar wall 12. The plurality of second connection positions 2141 are spaced apart along the extension direction of the strip segment 214, and the strip segment 214 is connected to the planar wall 12 through the plurality of second connection positions 2141.

[0045] Specifically, as shown in the figure, by setting multiple connection points on the arc-shaped segment 213 and the strip segment 214, the connection strength between the operating platform module 20 and the enclosure module 10 can be increased, thereby improving the stability of the entire steam generator compartment structure 100. Furthermore, the multiple connection points make it easier to connect the arc-shaped segment 213 to the arc-shaped wall 11 and to the strip segment 214 to its corresponding flat wall 12, resulting in easier operation and higher efficiency.

[0046] In one embodiment, a ladder 50 is connected between any two adjacent operating platforms 21. By setting a ladder 50 between any two ladders 50, maintenance personnel can pass between operating platforms 21 at different heights, which is convenient and efficient.

[0047] In one embodiment, each operating platform 21 is provided with a railing 60. By providing railings 60 on each operating platform 21, protection can be provided for maintenance personnel on the operating platform 21, preventing maintenance personnel from accidentally falling off the operating platform 21, thus improving safety.

[0048] It should be noted that the sequence numbers of the above embodiments of the present invention are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above embodiments are only optional embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made under the inventive concept of the present invention using the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are all included within the patent protection scope of the present invention.
