Description

Technical Field

[0001] The utility model relates to the technical field of box-type transformers, in particular to an accident oil pool for a box-type transformer platform. Background Art

[0002] With the rapid development of the new energy industry, the basic structural forms of box-type transformers in new energy projects are diverse, including underground box-type structures and above-ground platform structures. The above-ground platform structures are further divided into reinforced concrete structures and steel structures. Each method has its own advantages and disadvantages, and the site is crucial for the structural selection of the box-type transformer foundation. For example, the box-type transformer foundation structure in desert areas is generally an above-ground platform type, and the accident oil pool of the box-type transformer is not placed on the ground to prevent being buried by sand and dust.

[0003] In the above-ground platform structure, the reinforced concrete structure platform has a lower cost, but the construction process is complex, which directly affects the construction period. Although the cost of the steel structure platform is slightly higher than that of the reinforced concrete platform, the construction is simple and the construction period can be saved.

[0004] The construction process of the reinforced concrete oil pool is complex and the self-weight of the structure is large. Although the cost is low, the construction period is long, which has a direct impact on the subsequent installation work of the box transformer and the commissioning operation of the entire project.

Detailed implementation manners

[0054] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0055] As Figures 1 to 3 shown, an embodiment of the present utility model provides an accident oil pool for a box-type transformer platform, including:

[0056] a rectangular pool body structure with an open top;

[0057] a plurality of stiffening ribs are uniformly arranged on the side walls of the rectangular pool body structure;

[0058] a plurality of support ribs are arranged at the open end of the rectangular pool body structure;

[0059] the rectangular pool body structure is connected to the steel beam of the transformer platform.

[0060] In this embodiment, the rectangular pool structure with an open top enables the oil pool to conveniently receive any oil leakage from the transformer platform. The rectangular shape not only facilitates construction but also provides sufficient volume to accommodate a large amount of leaked oil, preventing environmental pollution or safety hazards caused by oil outflow. The open-top design also makes cleaning and maintenance work more convenient.

[0061] The setting of stiffening ribs is an important measure to enhance the structural strength of the pool. By evenly distributing the stiffening ribs, the rigidity and load-bearing capacity of the rectangular pool structure can be significantly improved, ensuring no deformation or damage occurs under the condition of being filled with oil or under external pressure, and guaranteeing the long-term stability and safety of the oil pool.

[0062] The function of the support ribs is to further enhance the support strength at the open end of the oil pool, preventing deformation or damage of the opening caused by the weight of the oil or external forces. The arrangement of the support ribs should be coordinated with the stiffening ribs to jointly form a stable and reliable support system, ensuring the overall stability of the oil pool.

[0063] The connection between the rectangular pool structure and the steel beam of the transformer platform can firmly fix the accident oil pool on the transformer platform, preventing displacement or tipping due to oil leakage or external forces. The connection method should adopt welding, high-strength bolts or other reliable connection methods, with welding being preferred to ensure the firmness and durability of the connection. At the same time, the design of the connection part should consider the needs of easy maintenance and inspection.

[0064] An oil outlet can be set in the rectangular pool structure to avoid the release when the oil in the rectangular pool structure is too much.

[0065] This technical solution can effectively simplify the construction process and shorten the construction period. At the same time, the steel structure accident oil pool can be centrally processed in the factory and directly welded on-site. The self-weight of the oil pool is also greatly reduced, which plays a very good role in optimizing the calculation of the columns of the box-type transformer platform. The splicing method of the steel structure accident oil pool can effectively ensure the sealing performance of the oil pool and is not easy to leak. The connection method between the steel structure accident oil pool and the steel beam ensures that the oil pool can be reliably connected to the steel beam.

[0066] In an optional embodiment of the present utility model, the rectangular pool structure includes: a first side wall 1, a second side wall 2, a third side wall 3, a fourth side wall 4, and an end wall 5;

[0067] The first side wall 1 is connected to the second side wall 2;

[0068] The first side wall 1 and the third side wall 3 are symmetrically arranged;

[0069] The second side wall 2 and the fourth side wall 4 are symmetrically arranged;

[0070] The second side wall 2 is connected to the third side wall 3;

[0071] The third side wall 3 is connected to the fourth side wall 4;

[0072] The first side wall 1 is connected to the fourth side wall 4;

[0073] A end wall 5 is connected to the first ends of the first side wall 1, the second side wall 2, the third side wall 3, and the fourth side wall 4.

[0074] In this embodiment, the first side wall 1, as a side of the rectangular pool structure, is directly connected to the second side wall 2 to form a right-angled side; the second side wall 2 is opposite and perpendicular to the first side wall 1, and is also connected to the third side wall 3 and the fourth side wall 4, and is another important side of the rectangular structure; the third side wall 3 is symmetrically arranged with the first side wall 1, that is, the angles formed by them with the end wall 5 are equal, and the lengths or heights may be the same (depending on the specific design). The third side wall 3 is also connected to the second side wall 2 and the fourth side wall 4; the fourth side wall 4 is symmetrically arranged with the second side wall 2, and is also a side of the rectangular structure, and is connected to the first side wall 1 through the end wall 5 to form a closed quadrilateral.

[0075] The end wall 5 connects the first ends of the first side wall 1, the second side wall 2, the third side wall 3, and the fourth side wall 4, thus enclosing the entire rectangular space; the end wall 5 may be the top of the entire structure (if the pool is placed horizontally), or it may be the bottom or one of the sides (depending on the specific design requirements).

[0076] All the side walls (the first side wall 1, the second side wall 2, the third side wall 3, the fourth side wall 4) and the end wall 5 are tightly combined by welding, bolt connection or other reliable connection methods to form a stable rectangular structure. Welding is preferred, and the thickness of the side walls and the end wall is preferably 6 mm; this connection method needs to ensure the sealing and load-bearing capacity of the structure to prevent oil leakage or structural damage.

[0077] Considering the stability and load-bearing capacity of the oil pool, a plurality of stiffening ribs may be evenly distributed on the side walls to enhance the rigidity and strength of the side walls; similarly, the end wall 5 may also be provided with a plurality of support ribs, and the specific setting is the same as the arrangement of the first support rib 14 and the second support rib 15 to provide additional support force.

[0078] In an alternative embodiment of the present utility model, a first splicing angle steel 6 is provided at the contact portion between the first side wall 1 and the end wall 5;

[0079] A second splicing angle steel 7 is provided at the contact portion between the second side wall 2 and the end wall 5;

[0080] A third splicing angle steel 8 is provided at the contact portion between the third side wall 3 and the end wall 5;

[0081] A fourth splicing angle steel 9 is provided at the contact part between the fourth side wall 4 and the end wall 5.

[0082] In this embodiment, a first splicing angle steel 6 is provided at the contact part between the first side wall 1 and the end wall 5. This angle steel is fixed between these two components by welding, bolt connection or other reliable connection methods, thereby enhancing the connection strength between them. Welding is preferred.

[0083] A second splicing angle steel 7 is provided at the contact part between the second side wall 2 and the end wall 5, providing additional structural support and connection stability.

[0084] A third splicing angle steel 8 is provided at the contact part between the third side wall 3 and the end wall 5 to ensure that the connection on this side is also firm and reliable.

[0085] The fourth splicing angle steel is provided at the contact part between the fourth side wall 4 and the end wall 5, completing the reinforcement of the entire rectangular pool structure at this end face.

[0086] The design of these splicing angle steels not only improves the overall strength of the structure, but also helps to disperse the impact of the oil liquid weight and external forces on the pool structure, reducing the possibility of single-point stress; in addition, they may also improve the seismic performance of the structure to a certain extent, ensuring that the pool structure can remain relatively stable during natural disasters such as earthquakes and reducing the risk of oil leakage.

[0087] The first splicing angle steel 6, the second splicing angle steel 7, the third splicing angle steel 8, and the fourth splicing angle steel 9 are preferably angle steels of L75*6.

[0088] In an alternative embodiment of the present utility model, a first side wall splicing angle steel 10 is provided at the contact part between the first side wall 1 and the second side wall 2;

[0089] A second side wall splicing angle steel 11 is provided at the contact part between the second side wall 2 and the third side wall 3;

[0090] A third side wall splicing angle steel 12 is provided at the contact part between the third side wall 3 and the fourth side wall 4;

[0091] A fourth side wall splicing angle steel 13 is provided at the contact part between the first side wall 1 and the fourth side wall 4.

[0092] In this embodiment, the first side wall splicing angle steel 10 is provided at the contact part between the first side wall 1 and the second side wall 2; this angle steel is fixed between these two side walls by welding, bolt connection or other reliable connection methods, thereby enhancing the connection strength between them. Welding is preferred.

[0093] The second sidewall splicing angle steel 11 is arranged at the contact part of the second sidewall 2 and the third sidewall 3; the function of this angle steel is also to provide additional structural support to ensure the firm and reliable connection between these two sidewalls.

[0094] The third sidewall splicing angle steel 12 is arranged at the contact part of the third sidewall 3 and the fourth sidewall 4, further strengthening the connection between these two sidewalls; this design helps to disperse the impact of the oil weight and external forces on the pool structure and reduces the risk of sidewall deformation.

[0095] The fourth sidewall splicing angle steel 13 is arranged at the contact part of the first sidewall 1 and the fourth sidewall 4. Although these two sidewalls are symmetric in the rectangular structure, their contact part still requires sufficient support to ensure the structural stability, and the design of this angle steel meets this requirement.

[0096] By arranging the splicing angle steels at these sidewall contact parts, the sidewall connection of the rectangular pool structure in this embodiment is significantly strengthened, which not only improves the overall strength of the structure but also makes the pool more stable and reliable when bearing the oil weight and external forces; in addition, this design also helps to reduce the risk of loosening or damage at the connection parts due to long-term use or environmental factors, thereby extending the service life of the pool.

[0097] The first sidewall splicing angle steel 10, the second sidewall splicing angle steel 11, the third sidewall splicing angle steel 12, and the fourth sidewall splicing angle steel 13 are preferably angle steels of L56*5.

[0098] In an optional embodiment of the present utility model, the support ribs include: a first support rib 14 and a second support rib 15;

[0099] The first support rib 14 is arranged parallel to the first sidewall 1;

[0100] The second support rib 15 is arranged parallel to the third sidewall 3.

[0101] In this embodiment, the first support rib 1 is arranged parallel to the first sidewall 1. This layout enables the first support rib to effectively share the load borne by the first sidewall, especially when the oil weight or external forces act on this sidewall. By adding the first support rib, the strength and stability of the first sidewall can be significantly improved, thereby enhancing the overall performance of the entire pool structure.

[0102] The second support rib 15 is designed to be arranged parallel to the third sidewall 3, and it can also provide additional support and reinforcement for the third sidewall. In the rectangular pool structure, the third sidewall may also be subjected to loads from different directions, especially under asymmetric loads. By installing the second support rib, it can be ensured that the third sidewall maintains sufficient rigidity and stability when bearing these loads.

[0103] The first support rib 14 and the second support rib 15 are respectively welded to the second side wall 2 and the fourth side wall 4; the first support rib 14 and the second support rib 15 are preferably angle steels of L75*6.

[0104] In an alternative embodiment of the present utility model, the horizontal distance between the first support rib 14 and the first side wall 1 is set according to a first preset distance;

[0105] The horizontal distance between the second support rib 15 and the third side wall 3 is set according to a second preset distance;

[0106] The distance between the first support rib 14 and the second support rib 15 is set according to a third preset distance.

[0107] In this embodiment, the horizontal distance between the first support rib 14 and the first side wall 1 should be based on factors such as the overall strength requirements of the pool body structure, the oil liquid weight distribution, and the possible external loads. By reasonably setting this distance, it can be ensured that the first support rib 14 can effectively share the load borne by the first side wall 1, while avoiding excessive impact on the internal space of the pool body. The maximum preferred distance is 600 mm.

[0108] The horizontal distance between the second support rib 15 and the third side wall 3 specifically depends on the symmetry of the pool body structure, the load distribution, and the design requirements. By adjusting this distance, it can be ensured that the second support rib 15 provides sufficient support and reinforcement for the third side wall 3. The maximum preferred distance is 600 mm.

[0109] The selection of the distance between the first support rib 14 and the second support rib 15 should consider the overall stability of the pool body structure, the interaction between the support ribs, and the possible load transfer path. By reasonably setting this distance, it can be ensured that the first support rib 14 and the second support rib 15 can work together to jointly improve the rigidity and load-bearing capacity of the pool body structure. The maximum preferred distance is 1000 mm.

[0110] In an alternative embodiment of the present utility model, the stiffening rib includes: a first stiffening rib 16 and a second stiffening rib 17;

[0111] The first stiffening rib 16 is set at a fourth preset distance from the first ends of the first side wall 1, the second side wall 2, the third side wall 3, and the fourth side wall 4;

[0112] The second stiffening rib 17 is set at a fifth preset distance from the second ends of the first side wall 1, the second side wall 2, the third side wall 3, and the fourth side wall 4;

[0113] The distance between the first stiffening rib 16 and the second stiffening rib 17 is set according to a sixth preset distance.

[0114] In this embodiment, the first stiffening rib 16 is disposed at the first ends of the first sidewall 1, the second sidewall 2, the third sidewall 3, and the fourth sidewall 4, and maintains a fourth preset distance from each sidewall. The preset distance is preferably 300 mm, and the selection of this distance should be determined based on the overall design of the pool structure, the load distribution, and the reinforcement effect of the stiffening rib. The first stiffening rib 16 can effectively improve the strength and stability of the pool structure at its first end.

[0115] The second stiffening rib 17 is disposed at the second ends of the above four sidewalls and maintains a fifth preset distance from each sidewall. The preset distance is preferably 300 mm, specifically depending on the symmetry of the pool structure, the load distribution, and the design requirements. The function of the second stiffening rib 17 is similar to that of the first stiffening rib 16, but it is for strengthening the second end of the pool structure.

[0116] The maximum preferred distance between the first stiffening rib 16 and the second stiffening rib 17 is 500 mm. The selection of this distance should take into account the overall stability of the pool structure, the interaction between the stiffening ribs, and the possible load transfer path. By reasonably setting this distance, it can be ensured that the first stiffening rib 16 and the second stiffening rib 17 can work together to jointly improve the overall rigidity and load-bearing capacity of the pool structure.

[0117] The first stiffening rib 16 and the second stiffening rib 17 are respectively welded to the first sidewall 1, the second sidewall 2, the third sidewall 3, and the fourth sidewall 4. The first stiffening rib 16 and the second stiffening rib 17 are preferably No. 8 channel steels.

[0118] In an alternative embodiment of the present utility model, the first sidewall 1 is connected to the first steel beam 19 of the transformer platform through a first connecting plate 18;

[0119] The second sidewall 2 is connected to the second steel beam 21 of the transformer platform through a second connecting plate 20;

[0120] The third sidewall 3 is connected to the third steel beam 23 of the transformer platform through a third connecting plate 22;

[0121] The fourth sidewall 4 is connected to the fourth steel beam 25 of the transformer platform through a fourth connecting plate 24.

[0122] In this embodiment, the first sidewall 1 is connected to the first steel beam 19 of the transformer platform through the first connecting plate 18, preferably by welding. The first sidewall 1 is firmly connected to the first steel beam 19 of the transformer platform. This connection method enables the first sidewall to effectively transfer the force to the steel beam when bearing the load, thereby improving the stability of the overall structure.

[0123] The second side wall 2 is connected to the second steel beam 21 of the transformer platform through the second connecting plate 20, preferably by welding. This layout ensures that the second side wall can also obtain sufficient support and can transfer the load to the steel beam structure when necessary.

[0124] The third side wall 3 is connected to the third steel beam 23 of the transformer platform through the third connecting plate 22, preferably by welding. This connection method further enhances the overall rigidity and stability of the pool structure, enabling the pool to better withstand loads from all directions.

[0125] The fourth side wall 4 is connected to the fourth steel beam 25 of the transformer platform through the fourth connecting plate 24, preferably by welding. In this way, all the side walls of the pool are firmly connected to the steel beam structure of the transformer platform, forming a stable and reliable whole.

[0126] The advantage of this connection method is that it can ensure that the pool structure maintains sufficient stability and safety when withstanding deformations and stresses caused by factors such as the weight of the oil, external forces, and temperature changes. At the same time, the design of the connecting plate also facilitates the adjustment and replacement during installation and maintenance.

[0127] The first connecting plate 18, the second connecting plate 20, the third connecting plate 22, and the fourth connecting plate 24 are preferably steel plates with a size of 150mm * 10mm;

[0128] The first steel beam 19, the second steel beam 21, the third steel beam 23, and the fourth steel beam 25 are preferably H-shaped steel with the specification of HW250 * 250b.

[0129] In an optional embodiment of the present utility model, a fifth splicing angle steel 26 is provided at the first side wall 1 and the first connecting plate 18;

[0130] A sixth splicing angle steel 27 is provided at the second side wall 2 and the second connecting plate 20;

[0131] A seventh splicing angle steel 28 is provided at the third side wall 3 and the third connecting plate 22;

[0132] An eighth splicing angle steel 29 is provided at the fourth side wall 4 and the fourth connecting plate 24.

[0133] In this embodiment, this design further enhances the connection strength between the rectangular pool and its support structure (i.e., the steel beam of the transformer platform). The splicing angle steel, as a reinforcement member, is installed at the contact part between the side wall and the connecting plate and is fixed together by welding, bolt connection, or other reliable connection methods, preferably by welding.

[0134] The splicing angle steel can disperse and bear the load from the side wall, preventing the connection part from being damaged due to stress concentration.

[0135] By adding additional structural supports, the spliced angle steel helps maintain the overall stability of the pool structure and reduces deformation caused by external forces or temperature changes.

[0136] The design of the spliced angle steel makes the installation process easier and also facilitates maintenance and replacement when needed.

[0137] Since the spliced angle steel can bear large loads and maintain the stability of the structure, they help extend the service life of the pool and its support structure.

[0138] By arranging spliced angle steels (the fifth spliced angle steel 26, the sixth spliced angle steel 27, the seventh spliced angle steel 28, and the eighth spliced angle steel 29 respectively) between the first side wall 1 and the first connecting plate 18, the second side wall 2 and the second connecting plate 20, the third side wall 3 and the third connecting plate 22, and the fourth side wall 4 and the fourth connecting plate 24, the overall rigidity and stability of the rectangular pool structure are further improved in this embodiment.

[0139] The fifth spliced angle steel 26, the sixth spliced angle steel 27, the seventh spliced angle steel 28, and the eighth spliced angle steel 29 are preferably angle steels of L75*6.

[0140] In an alternative embodiment of the present utility model, both the first stiffening rib 16 and the second stiffening rib 17 have a channel-shaped cross-section.

[0141] In this embodiment, the channel-shaped cross-section (also known as the C-shaped or U-shaped cross-section) is very common in structural engineering because they have excellent flexural rigidity and load-bearing capacity;

[0142] The design of the channel-shaped cross-section enables the material to be more effectively distributed in the areas where stress needs to be borne, thereby improving the load-bearing capacity of the stiffening rib.

[0143] Compared with solid cross-sections, the channel-shaped cross-section can significantly reduce weight while maintaining the same or higher strength, which is particularly important for structures that need to control the overall weight (such as the pool on the transformer platform).

[0144] The design of the channel-shaped cross-section enables more efficient use of materials and reduces unnecessary material waste.

[0145] The channel-shaped cross-section can usually be manufactured by standard metal processing methods (such as rolling, cutting, and welding), and is easy to connect and install with other structural components.

[0146] The opening direction of the channel-shaped cross-section is usually perpendicular to the expected bending direction, which enables them to effectively resist bending stress and thus improves the overall stability of the structure.

[0147] After optimization analysis, the maximum size of the oil sump is 2800 mm in length, 1800 mm in width, and 1800 mm in height.

[0148] The above is the preferred embodiment of the present invention.
