Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, specifically to a cover plate, a cover plate assembly, a container, and an energy storage device. Background Technology

[0002] The top covers of shipping containers are typically flat and horizontally installed. Due to their own weight, as well as water and dust accumulation, the central area of ​​the cover may bend downwards, causing deformation and creating pits. These pits easily accumulate water, which is difficult to drain. Prolonged immersion in water can damage the paint layer of the cover, leading to corrosion. Furthermore, drainage from horizontal covers is random, while containers have doors on their sides. If water drains into these doors, it can cause water to enter the container or accelerate the aging and failure of the door seals.

[0003] Some industry designs involve setting the top of the container frame at different heights, with covers placed on the frame to create varying elevations. This design results in different lever arms at different heights of the frame during container lifting, causing the container's center of gravity to tilt, potentially damaging the frame and leading to container malfunction. Utility Model Content

[0004] The purpose of this invention is to provide a cover plate, a cover plate assembly, a container, and an energy storage device to solve the problems of water accumulation, corrosion, and damage caused by uneven frame heights resulting from horizontal installation of flat plates.

[0005] To achieve the objectives of this utility model, the following technical solution is provided:

[0006] In a first aspect, this utility model provides a cover plate for a container, the container including a first top crossbeam and a second top crossbeam located at the same height and opposite to each other; the cover plate includes:

[0007] The plate includes a first surface, the first surface including a first edge and a second edge opposite each other in a first direction;

[0008] A first flange is connected to the plate body and protrudes from the first surface, and the first flange and the first edge have a first preset distance in the first direction;

[0009] Wherein, the first flange protrudes from the end face of the first surface and is used to be mounted on the first top crossbeam, and the second edge is used to be mounted on the second top crossbeam, so that the height of the plate at the first edge is higher than the height at the second edge.

[0010] In one embodiment, the first preset distance is 0mm-30mm.

[0011] In one embodiment, the cover plate further includes a second flange, which is connected to the plate body and protrudes from the first surface. The second flange and the second edge have a second preset distance in the first direction. The height of the second flange protruding from the first surface is lower than the height of the first flange protruding from the first surface.

[0017] Secondly, this utility model also provides a cover plate assembly for a container, the container including a first top crossbeam, a second top crossbeam, a first top longitudinal beam and a second top longitudinal beam at the same height, the first top crossbeam and the second top crossbeam being opposite each other, and the first top longitudinal beam and the second top longitudinal beam being opposite each other.

[0018] The cover plate assembly includes a first baffle, a second baffle, and a cover plate as described in any of the various embodiments of the first aspect, wherein the first baffle is connected to one end of the cover plate in a second direction, and the second baffle is connected to the other end of the cover plate in the second direction;

[0019] The cover plate is used to be installed on the first top crossbeam and the second top crossbeam, the first baffle is used to be installed on the first top longitudinal beam, and the second baffle is used to be installed on the second top longitudinal beam.

[0020] In one embodiment, the first baffle includes a main board and a rain guide plate. The main board is used to be mounted on the first top longitudinal beam. One end of the main board in the second direction is connected to the cover plate. One end of the rain guide plate is connected to the other end of the main board in the second direction. The end of the rain guide plate in the second direction away from the main board is lower than the main board.

[0021] In one embodiment, the first baffle further includes two fourth flanges. The main board is connected to one of the fourth flanges at each end in the first direction. The fourth flanges protrude from the main board in the same direction as the first flanges. The height of the fourth flanges protruding from the main board in the second direction from the cover plate toward the direction away from the cover plate gradually decreases. The fourth flange is used to be installed on the first top crossbeam, and the other fourth flange is used to be installed on the second top crossbeam.

[0022] In one embodiment, there are multiple cover plates, which are sequentially connected in the second direction. The first baffle is connected to one of the multiple cover plates on the outer side in the second direction, and the second baffle is connected to another of the multiple cover plates on the outer side in the second direction.

[0023] Thirdly, this utility model also provides a container, comprising:

[0024] A first top crossbeam, a second top crossbeam, a first top longitudinal beam, and a second top longitudinal beam are located at the same height, with the first top crossbeam and the second top crossbeam facing each other, and the first top longitudinal beam and the second top longitudinal beam facing each other;

[0025] A door assembly connected to the first top crossbeam; the door assembly is capable of opening and closing, and when the door assembly is closed, the container is in a closed state; and

[0026] In the second aspect, a cover plate assembly is provided in any of the various embodiments, wherein the cover plate is mounted on the first top crossbeam and the second top crossbeam, the first baffle is mounted on the first top longitudinal beam, and the second baffle is mounted on the second top longitudinal beam.

[0030] The cover plate of this utility model features a first flange protruding from the first surface, which is mounted on the first top crossbeam. The second edge is mounted on the second top crossbeam, causing the plate to tilt. The plate is higher at one end of the first top crossbeam and lower at the other end of the second top crossbeam. This allows rainwater to flow from higher to lower, preventing water accumulation on the plate. Even with a slight downward bend in the middle, the overall structure remains higher at one end than the other, reducing the likelihood of water accumulation and preventing prolonged water immersion that could damage the paint layer. Furthermore, the higher height of the cover plate at the first top crossbeam directs drainage. Stable rather than random, water on the cover will not drain from the first top crossbeam to the door assembly installed at the first crossbeam, avoiding water ingress into the container or accelerated aging and failure of the door assembly's sealing strips. At the same time, because the first flange raises the height of one end of the panel, rather than achieving the tilt of the cover through the different heights of the container's frame, the first top crossbeam, second top crossbeam, first top longitudinal beam, and second longitudinal beam of the container are at the same height. That is, the top height of the container's frame is the same, and the lever arm is the same when the container is lifted, which will not cause the container's center of gravity to tilt and avoid damage to the frame.

When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0058] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0059] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0060] Please refer to Figure 1 and Figure 2 This utility model provides an energy storage device, including a battery device (not shown) and a container 100, wherein the battery device is housed within the container 100.

[0061] The battery device may include several battery packs and corresponding supporting, electrical control, and fire protection structures, without limitation. The battery device stores electrical energy and can power electrical equipment when needed. The battery device is housed within container 100, allowing it to be transported along with container 100, or the battery device can be loaded into container 100 after it has been transported to its destination. Container 100 can be installed outdoors, providing waterproof and dustproof protection for the battery device inside.

[0062] The container 100 is a uniquely designed structure in this embodiment of the utility model, which can overcome the problems of existing containers where the cover is flat and horizontally installed, and the frame is set with different heights.

[0063] The container 100 of this utility model embodiment will be described in detail below.

[0064] refer to Figures 1 to 3 For ease of explanation, a coordinate system XYZ is established, including a first direction X, a second direction Y, and a third direction Z, which are mutually perpendicular. The first direction X represents the width of container 100, the second direction Y represents the length of container 100, and the third direction Z represents the height of container 100. In this paper, "bottom" and "top" of container 100 refer to the two opposite ends of container 100 along the third direction Z, with the bottom facing the Earth's center. The bottom is used to place the container on a supporting surface such as the ground. "Height" in this paper refers to the height along the third direction Z, measured with the bottom as the reference point, or with the supporting surface as the reference point. "Above" and "below" refer to the orientation along the third direction Z, with "below" being closer to the Earth's center than "above."

[0065] The container 100 includes a frame 10, a floor assembly (not shown), a side panel assembly 20, a top panel assembly 30, a cover assembly 40, and a door assembly 80. The frame 10 constitutes the basic framework of the container 100 and is used as a structural foundation for hoisting, as well as for installing the floor assembly, side panel assembly 20, top panel assembly 30, cover assembly 40, and door assembly 80.

[0066] The frame 10 includes a bottom beam 11 at the bottom of the container 100, a top beam 12 at the top of the container 100, several uprights 13 located between the bottom beam 11 and the top beam 12, and several corner fittings 14. The bottom beam 11 and the top beam 12 are at the same height and are arranged parallel to each other. The uprights 13 extend in a third direction Z. The bottom beam 11 and the uprights 13 are connected by corner fittings 14, and the top beam 12 and the uprights 13 are also connected by corner fittings 14. The corner fittings 14 are used for lifting the container 100 and may have lifting holes.

[0067] The floor assembly is mounted on the bottom beam 11 of the frame 10 and is used to support the materials loaded inside the container 100, such as battery devices. The side panel assembly 20 is mounted between the bottom beam 11 and the top beam 12 of the frame 10 and can be connected to the uprights 13. The side panel assembly 20 is used to seal part of the sides of the container 100. The door assembly 80 is also mounted between the bottom beam 11 and the top beam 12 of the frame 10 and can be connected to the uprights 13. The door assembly 80 also seals the remaining sides of the container 100 and can be opened and closed. When the door assembly 80 is closed, the container 100 is in a closed state. The top panel assembly 30 is mounted on the top beam 12 and is used to install fire-fighting pipes, electrical components, etc., located inside the container 100. The cover assembly 40 is placed on the top beam 12 to cover the container 100 to prevent rainwater, dust, etc., from entering the interior of the container 100.

[0068] The top beam 12 includes a first top horizontal beam 121, a second top horizontal beam 122, a first top longitudinal beam 123, and a second top longitudinal beam 124, all located at the same height. The first top horizontal beam 121 and the second top horizontal beam 122 both extend along a second direction Y and are opposite each other in a first direction X. The first top longitudinal beam 123 and the second top longitudinal beam 124 both extend along the first direction X and are opposite each other in the second direction Y. In this embodiment of the invention, the side panel assembly 20 is connected between the second top horizontal beam 122 and the bottom beam 11, and also between the second top longitudinal beam 124 and the bottom beam 11. The door assembly 80 is connected between the first top horizontal beam 121 and the bottom beam 11. A door assembly 80 may also be provided between the first top longitudinal beam 123 and the bottom beam 11.

[0069] The first top crossbeam 121, the second top crossbeam 122, the first top longitudinal beam 123, and the second top longitudinal beam 124 are connected by multiple corner fittings 14. Specifically, there are four corner fittings 14 located on the top of the container 100. The first top crossbeam 121, the second top crossbeam 122, the first top longitudinal beam 123, and the second top longitudinal beam 124 together form a rectangular structure, and the four corners of the rectangle are connected by corner fittings 14. The multiple corner fittings 14 are higher than the first top crossbeam 121, the second top crossbeam 122, the first top longitudinal beam 123, and the second top longitudinal beam 124 to facilitate the installation of cables during hoisting and to avoid interference.

[0070] Optionally, the top plate assembly 30 includes multiple top support beams 31 and multiple top plates 32. The top support beams 31 extend along a first direction X and are connected at both ends to the opposite sides of the first top crossbeam 121 and the second top crossbeam 122. The multiple top support beams 31 are spaced apart along a second direction Y. The top plates 32 are connected to the gaps between the first top crossbeam 121, the second top crossbeam 122, the first top longitudinal beam 123, the second top longitudinal beam 124, and the top support beams 31 to close the top of the container 100. Heavier structures can be hoisted under the top support beams 31, and lighter structures can be hoisted under the top plates 32. A mezzanine space 33 is formed between the cover plate assembly 40 and the top plate assembly 30. This mezzanine space 33 can be used to install insulation layers (not shown), etc. In this embodiment of the utility model, the height of the top plate assembly 30 does not exceed the height of the top beam 12, and there is no direct connection between the cover plate assembly 40 and the top plate assembly 30, that is, the top support beam 31 and the top plate 32 are spaced apart from the cover plate assembly 40.

[0071] The container 100 of this utility model embodiment is designed with a unique cover plate assembly 40, while the frame 10 is a conventional frame 10, that is, the first top crossbeam 121, the second top crossbeam 122, the first top longitudinal beam 123 and the second top longitudinal beam 124 are at the same height. There is no need to design the frame 10 with different heights to achieve the purpose of tilting the cover plate assembly 40, nor is it necessary to set the top plate assembly 30 higher to support the cover plate assembly 40 to achieve the purpose of tilting it.

[0072] The cover plate assembly 40 of this utility model embodiment will be described in detail below.

[0073] refer to Figure 3 and Figure 4 The cover plate assembly 40 includes a cover plate 50, a first baffle 60, and a second baffle 70. The first baffle 60 is connected to one end of the cover plate 50 in the second direction Y, and the second baffle 70 is connected to the other end of the cover plate 50 in the second direction Y. The cover plate 50 is used to be installed on the first top crossbeam 121 and the second top crossbeam 122, the first baffle 60 is used to be installed on the first top longitudinal beam 123, and the second baffle 70 is used to be installed on the second top longitudinal beam 124. The cover plate 50 plays a primary role in protecting against rain and dust, while the first baffle 60 and the second baffle 70 play a secondary role in protecting against rain and dust.

[0074] The cover plate 50 can be fixed to the first top crossbeam 121 and the second top crossbeam 122 by welding. The first baffle plate 60 and the second baffle plate 70 can be fixed to the cover plate 50 by welding. The first baffle plate 60 can be fixed to the first top longitudinal beam 123 by welding. The second baffle plate 70 can be fixed to the second top longitudinal beam 124 by welding. After the cover plate 50, the first baffle plate 60, the second baffle plate 70 and the top beam 12 are welded and fixed, there are no gaps at the joints, which prevents water leakage or dust ingress.

[0075] Due to the presence of corner fitting 14, cover plate 50 cannot be installed from one end of container 100 along its length to the other. To avoid interference, a first baffle 60 and a second baffle 70 are provided at both ends adjacent to the length of container 100 (i.e., the second direction Y). It should be understood that the shape and size of container 100 are standardized, and its length (the dimension along the second direction Y) is significantly greater than its width (the dimension along the first direction X). Therefore, the dimensions of cover plate 50 in the second direction Y should be maximized, while the dimensions of the first baffle 60 and the second baffle 70 in the second direction Y should be minimized.

[0076] Optionally, the height of the first baffle 60 at the corner piece 14 is lower than the height of the corner piece 14. In other words, the height of the first baffle 60 near the corner piece 14 connected to the first top longitudinal beam 123 is lower than the height of the corner piece 14. Optionally, in the orthographic projection of the first direction X, the height of the two corner pieces 14 connected to the first top longitudinal beam 123 is higher than the height of the first baffle 60 at the corresponding position to avoid interference during hoisting. Similarly, the height of the second baffle 70 near the corner piece 14 connected to the second top longitudinal beam 124 is also lower than the height of the corner piece 14 to avoid interference during hoisting.

[0077] Optionally, there are multiple cover plates 50, which are sequentially connected in the second direction Y. The first baffle 60 is connected to one of the outermost cover plates 50 in the second direction Y, and the second baffle 70 is connected to another outermost cover plate 50 in the second direction Y. Since the container 100 is relatively long, using only one cover plate 50 would be difficult to manufacture. Using multiple cover plates 50 sequentially connected along the second direction Y reduces the manufacturing difficulty. The multiple cover plates 50 can be fixed together by welding. The first baffle 60 can also be fixed to the cover plate 50 closest to the first top longitudinal beam 123 by welding, and the second baffle 70 can also be fixed to the cover plate 50 closest to the second top longitudinal beam 124 by welding. For example, as shown... Figure 4 As shown, there are four cover plate assemblies 40.

[0078] refer to Figure 3 and Figure 5 The cover plate 50 includes a plate body 51 and a first flange 52, which is connected to the plate body 51.

[0079] The plate 51 includes a first surface 511 and a second surface 512 facing away from each other. The first surface 511 faces the frame 10 of the container 100, and the second surface 512 faces the external environment and is used to collect rainwater, dust, etc. Optionally, the plate 51 is generally a rectangular flat plate, that is, the first surface 511 and the second surface 512 can be mutually parallel planes. The thickness of the plate 51 can be 1.5mm-3mm, specifically 1.5mm, 2mm, 2.5mm, 3mm, etc., without limitation. Optionally, the plate 51 may include a plurality of protrusions 513 recessed from the first surface 511 and protruding from the second surface 512. The plurality of protrusions 513 can extend along the first direction X and be spaced apart in the second direction Y. The protrusions 513 can be formed by stamping the plate 51. The protrusions 513 are used to enhance the structural strength of the plate 51 and reduce the degree of downward bending of the plate 51. Optionally, in embodiments where the cover assembly 40 has a plurality of cover plates 50, the dimension of the cover plate 50 along the first direction X is greater than the dimension along the second direction Y.

[0080] The first surface 511 of the plate 51 includes a first edge 514 and a second edge 515 opposite each other in the first direction X. A first flange 52 is connected to the plate 51 near the first edge 514 and protrudes from the first surface 511, with the first flange 52 and the first edge 514 having a first preset distance in the first direction X. The first flange 52 extends along the second direction Y and is approximately parallel to the first edge 514. The end face of the first flange 52 protruding from the first surface 511 is used for mounting to the first top crossbeam 121, and the second edge 515 is used for mounting to the second top crossbeam 122, so that the height of the plate 51 at the first edge 514 is higher than the height at the second edge 515. Since the first flange 52 is mounted to the first top crossbeam 121, the plate 51 can form a structure with one end higher than the other, with the higher end corresponding to the first top crossbeam 121 and the lower end corresponding to the second top crossbeam 122.

[0081] In this embodiment of the utility model, the cover plate 50 is provided with a first flange 52 protruding from the first surface 511. The first flange 52 is installed on the first top crossbeam 121, and the second edge 515 is installed on the second top crossbeam 122, causing the plate 51 to be inclined. The plate 51 is higher at one end of the first top crossbeam 121 and lower at one end of the second top crossbeam 122. Rainwater can flow from the higher to the lower, preventing water accumulation on the plate 51. Even if the middle of the plate 51 is slightly bent downwards, the plate 51 has an overall structure that is higher at one end and lower at the other, making it less likely to form pits for water accumulation and preventing water from soaking the cover plate 50 for a long time and damaging the paint layer. In addition, the cover plate 50 is higher at the first top crossbeam 121, ensuring a stable drainage direction. It is random, and water on the cover plate 50 will not drain from the first top crossbeam 121 to the door assembly 80 installed at the first crossbeam, thus avoiding water ingress into the container 100 or accelerated aging and failure of the sealing strip of the door assembly 80. At the same time, since the first flange 52 raises the height of one end of the plate 51, rather than achieving the tilt of the cover plate 50 through the different heights of the frame 10 of the container 100, the first top crossbeam 121, the second top crossbeam 122, the first top longitudinal beam 123 and the second top longitudinal beam 124 of the container 100 are at the same height. That is, the top height of the frame 10 of the container 100 is the same, and the lever arm is the same when the container 100 is lifted, which will not cause the center of gravity of the container 100 to tilt and avoid damage to the frame 10.

[0082] Since the height of a container 100 is typically 2896mm, which is higher than a person's height, the existing method of using a standard flat, horizontally installed container is prone to water accumulation, which is difficult to detect during routine inspections. It is usually only discovered after the cover plate has been corroded and damaged, potentially leading to significant risks. However, the cover plate 50 of this embodiment, by incorporating a first flange 52 to form an inclined structure, possesses excellent drainage performance and significantly improves reliability.

[0083] Using ordinary flat plates, to avoid pits, the flatness must be strictly controlled during the production process, which significantly increases the processing difficulty. However, in the solution of this utility model embodiment, even if the plate 51 is slightly bent, it does not affect the overall structure of the plate 51, which is higher at one end and lower at the other. It will not produce pits that would accumulate water due to bending, which can significantly reduce the flatness requirements of the plate 51, reduce the processing difficulty, and thus reduce the cost.

[0084] Optional, see reference Figure 9 and Figure 10 The distance between the first flange 52 and the first edge 514 in the first direction X (i.e., the first preset distance) is 0mm-30mm. This distance can specifically be 0mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, etc. Figure 9 An embodiment is shown where the distance between the first flange 52 and the first edge 514 in the first direction X is 0 mm. For example... Figure 10 An embodiment is shown in which the distance between the first flange 52 and the first edge 514 in the first direction X is greater than 0 mm. It should be understood that this distance refers to the closest distance between the first flange 52 and the first edge 514 in the first direction X.

[0085] Optionally, the first flange 52 may be perpendicular to the first surface 511 or may have an inclined angle, without limitation.

[0086] In one embodiment, reference Figure 9 and Figure 10 The cover plate 50 also includes a second flange 53, which is connected to the plate body 51 near the second edge 515 and protrudes from the first surface 511. The second flange 53 and the second edge 515 have a second preset distance in the first direction X. The height of the second flange 53 protruding from the first surface 511 is lower than the height of the first flange 52 protruding from the first surface 511. The end face of the second flange 53 protruding from the first surface 511 is used to be installed on the second top crossbeam 122.

[0087] In this embodiment, the second edge 515 of the plate 51 is connected to the second top beam 122 via the second flange 53. That is, the lower end of the plate 51 is connected to the second top beam 122 via the second flange 53, and the second edge 515 is indirectly disposed on the second top beam 122. In this way, a structure in which one end of the plate 51 is higher than the other end can be achieved.

[0088] Similar to the first flange 52, the second flange 53 also extends along the second direction Y and can be parallel to the second edge 515. The distance between the second flange 53 and the second edge 515 in the first direction X (i.e., the second preset distance) is 0mm-30mm. This distance can specifically be 0mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, etc. Figure 9 An embodiment is shown in which the distance between the second flange 53 and the second edge 515 in the first direction X is 0 mm. Figure 10 An embodiment is shown in which the distance between the second flange 53 and the second edge 515 in the first direction X is greater than 0 mm. The second flange 53 may be parallel to the first flange 52 or may not be parallel, and there is no limitation.

[0089] In other embodiments, refer to Figure 3 , Figure 5 , Figure 7 and Figure 11 Alternatively, the second flange 53 can be omitted, and the second edge 515 can be directly installed onto the second top beam 122.

[0090] In one embodiment, reference Figure 5 , Figure 6 and Figure 8The cover plate 50 also includes a third flange 54, which is connected to the plate body 51 and protrudes from the first surface 511. The third flange 54 extends along the first direction X. The third flange 54 is used to enhance the structural strength of the plate body 51 and reduce the degree of downward bending of its middle part.

[0091] Optionally, one end of the third flange 54 is connected to the first flange 52, and the other end extends to the vicinity of the second edge 515. The end face of the third flange 54 protruding from the first surface 511 is used for mounting to the first top crossbeam 121 and the second top crossbeam 122. Specifically, the end face of the third flange 54 protruding from the first surface 511 near the first edge 514 is used for mounting to the first top crossbeam 121, and the end face of the third flange 54 protruding from the first surface 511 near the second edge 515 is used for mounting to the second top crossbeam 122. In this embodiment, the third flange 54 is connected to the first flange 52 and can be welded and fixed to the first top crossbeam 121 and the second top crossbeam 122, which can further improve the structural strength of the plate 51 and reduce the degree of downward bending.

[0092] Further optional, see reference Figure 8 and Figure 9 In an embodiment with a second flange 53, the end of the third flange 54 away from the first flange 52 can be connected to the second flange 53, which can also enhance the structural strength of the plate 51.

[0093] Optional, see reference Figures 9 to 11 The height of the third flange 54 protruding from the first surface 511 gradually decreases from the first edge 514 to the second edge 515, and the end face of the first flange 52 protruding from the first surface 511 and the end face of the third flange 54 protruding from the first surface 511 are on the same plane.

[0094] refer to Figure 9 and Figure 10 In the embodiment where the second flange 53 is provided, the third flange 54 is generally trapezoidal in shape. (See reference...) Figure 11 In embodiments where the second flange 53 is omitted, the third flange 54 is approximately triangular in shape.

[0095] refer to Figure 7 and Figure 11 In embodiments where the second flange 53 is omitted, the height of the third flange 54 protruding from the first surface 511 may be very small near the second edge 515. During processing, it can be formed by first connecting it to the first surface 511 or by bending. Figure 11 The triangles with solid lines and the triangles with dashed lines are combined into a larger piece, which is then cut. Figure 11 The triangular part of the dashed line in the middle, and the triangular part of the remaining solid line can form the third flange 54.

[0096] Optional, see reference Figures 5 to 8 The first surface 511 also includes a third edge 516 and a fourth edge 517 opposite each other in the second direction Y. The number of third flanges 54 is at least two, with the third edge 516 connected to one third flange 54 and the fourth edge 517 connected to another third flange 54.

[0097] The number of third flanges 54 can be 2, 3, 4, etc. Besides being located at the third edge 516 and the fourth edge 517, third flanges 54 can also be provided between the third edge 516 and the fourth edge 517. Multiple third flanges 54 can be evenly spaced along the second direction Y, further enhancing the structural strength of the plate 51. (Reference) Figure 4 The third flanges 54 located at the third edge 516 and the fourth edge 517 can be used for welding and fixing with the first baffle 60 and the second baffle 70. In embodiments where there are multiple cover plates 50, the third flanges 54 located at the third edge 516 and the fourth edge 517 can be used for welding and fixing adjacent cover plates 50. By providing the third flange 54 located at the Y-end of the plate body 51 in the second direction, the welding area with adjacent structures can be increased, the welding process can be more resistant, good welding results can be achieved more easily, and deformation caused by welding can be reduced.

[0098] Optional, see reference Figure 5 The first flange 52 is connected to the first edge 514, and the plate 51, the first flange 52, the third flange 54 connected to the third edge 516, and the third flange 54 connected to the fourth edge 517 form an integral structure formed by bending a plate. Forming the first flange 52 and the third flanges 54 at both ends of the second direction Y by bending a single plate is a simple process with high overall structural strength, reducing deformation caused by processes such as welding. Optionally, refer to... Figure 8 In embodiments with a second flange 53, the second flange 53 may also be an integral structure formed by bending a plate body 51.

[0099] In one embodiment, reference Figures 1 to 3 and Figure 12 The first baffle 60 includes a main board 61 and a rain guide plate 62. The main board 61 is used to be installed on the first top longitudinal beam 123, and one end of the main board 61 in the second direction Y is connected to the cover plate 50. One end of the rain guide plate 62 is connected to the other end of the main board 61 in the second direction Y, and the end of the rain guide plate 62 in the second direction Y away from the main board 61 is lower than the main board 61.

[0100] The main board 61 is roughly a rectangular flat plate, with its length direction defined by the first direction X and its width direction by the second direction Y. As described above, a first baffle 60 and a second baffle 70 are provided at the location of the corner piece 14. The main board 61 has a notch 611 at its end in the length direction corresponding to the corner piece 14. The inner wall of the notch 611 includes two vertical sidewalls, which are used to tightly abut against the two sides corresponding to the corner piece 14. The main board 61 can be welded and fixed to the first top longitudinal beam 123, and can be directly or indirectly connected to the first top transverse beam 121 and the second top transverse beam 122, ensuring a seal at the first baffle 60 without gaps, preventing water leakage and dust ingress into the container 100.

[0101] The rain deflector 62 can also be roughly a rectangular flat plate, with its length direction being the first direction X and its width direction being roughly the second direction Y. The rain deflector 62 and the main plate 61 can also be an integral structure formed by bending a single plate. The end of the rain deflector 62 away from the main plate 61 is located on the side of the first top longitudinal beam 123 in the second direction Y, away from the first top longitudinal beam 123. That is, the end of the rain deflector away from the main plate 61 is further outward than the side of the container 100 in the length direction. Water on the main plate 61 is drained onto the rain deflector 62. Because the rain deflector 62 is inclined and the end away from the main plate 61 is lower, it can drain water to the outside of the side of the container 100 in the length direction, avoiding water ingress, corrosion, and other problems caused by water washing onto the side of the container 100.

[0102] In one embodiment, reference Figure 12 and Figure 13 The first baffle 60 also includes two fourth flanges 63. The main board 61 has a fourth flange 63 connected to each end in the first direction X. Specifically, one fourth flange 63 is connected to one end of the main board 61 adjacent to the first direction X, and another fourth flange 63 is connected to the other end of the main board 61 adjacent to the first direction X. The fourth flanges 63 protrude from the main board 61 in the same direction as the first flange 52. In the second direction Y, the height of the fourth flanges 63 protruding from the cover plate 50 towards the direction away from the cover plate 50 gradually decreases. The fourth flange 63 is used to be mounted to the first top crossbeam 121, and the other fourth flange 63 is used to be mounted to the second top crossbeam 122.

[0103] The fourth flange 63 is similar to the third flange 54 mentioned above, and can be trapezoidal or triangular, such as... Figure 13 An embodiment where the fourth flange 63 is triangular is shown. By setting the fourth flange 63, the main board 61 can form an inclined structure, with the end of the main board 61 connected to the cover plate 50 being higher and the end away from the cover plate 50 being lower, allowing rainwater to flow from the high end to the low end and preventing water accumulation on the main board 61.

[0104] Optionally, a flange for welding can also be provided at the end of the main board 61 away from the rain guide plate 62, similar to the third flange 54 provided on the third edge 516 or the fourth edge 517 of the cover plate 50 mentioned above, which can enhance the welding process tolerance.

[0105] The structure of the second baffle 70 is basically the same as that of the first baffle 60, and can be used as a reference without further explanation.
