However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0052] The preferred embodiments of this utility model will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0053] In this document, ordinal numbers such as “first” and “second” used in this invention are merely identifiers and do not have any other meaning, such as a specific order.

[0054] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0055] First Implementation Method

[0056] This utility model provides a top structure for a container. The container can be a bulk cargo container. The top structure is fixedly installed on the top of the container to close the top of the container. The top structure has a top opening 112 to allow loading and unloading of bulk cargo such as grain, coal, and ore. When the top opening cover 130 covering the top opening 112 is opened, it can reduce the amount of water accumulated in the top structure entering the container through the top opening 112.

[0057] Please refer to Figures 1 to 3 The top structure includes a top wall 110. The top wall 110 is disposed on the top of the container to close the top of the container. The top wall 110 includes a cover body and a support member 120. The support member 120 is a circumferentially closed support ring structure. Thus, the support member 120 is circumferentially disposed at the top opening 112. The support member 120 has a sealing wall 121.

[0058] like Figure 2 and Figure 3 As shown, the top structure also includes a top hole cover 130. One end of the top hole cover 130 is rotatably connected to the top wall 110 via a pivot 140. Thus, the top hole cover 130 can rotate between a closed position and an open position. When the top hole cover 130 is in the closed position, it closes the top hole 112. When the top hole cover 130 is in the open position, a portion of the top hole cover 130 moves away from the top wall 110, thereby opening the top hole 112. At this time, bulk cargo can be loaded and unloaded or containers can be entered and exited through the top hole 112.

[0059] Please continue to refer to this. Figure 2 and Figure 3 The top cover 130 includes a body 131. The body 131 has a plate-like structure. The body 131 is rotatably connected to the top wall 110 via a pivot 140, so that the top cover 130 can rotate.

[0060] like Figure 2 and Figure 3As shown, the top cover 130 also includes a sealing groove assembly. The sealing groove assembly includes a sealing groove member 132. The sealing groove member 132 is a circumferentially closed sealing annular structure. The sealing groove member 132 includes a first sidewall 133, a connecting wall 134, and a second sidewall 135. Both the connecting wall 134 and the second sidewall 135 are flat plate structures. The first sidewall 133 is located on the outer side of the second sidewall 135 away from the center of the sealing annular structure. The upper end of the sealing groove assembly is welded to the body 131. Specifically, the upper surface of the connecting wall 134 is attached to and welded to the body 131. The upper ends of the first sidewall 133 and the second sidewall 135 are respectively connected to the opposite ends of the connecting wall 134 to form a downward-opening sealing groove 136.

[0061] In other words, the first sidewall 133 is a circumferentially closed first annular structure. The second sidewall 135 is a circumferentially closed second annular structure. The connecting wall 134 is a circumferentially closed connecting annular structure. The connecting annular structure is located on the outer side of the second annular structure, away from its center. The first annular structure is located on the outer side of the connecting annular structure, away from the second annular structure. The first annular structure is the outer ring of the sealing annular structure. The second annular structure is the inner ring of the sealing annular structure.

[0062] like Figure 2 and Figure 3 As shown, the top cover 130 also includes a sealing strip 150. The sealing strip 150 is a circumferentially closed annular structure. The sealing strip 150 is disposed within the sealing groove 136. When the top cover 130 is in the closed position, the sealing wall 121 is located between the first side wall 133 and the second side wall 135. The sealing strip 150 abuts against the sealing wall 121 to seal the gap between the top cover 130 and the top wall 110.

[0063] At least a portion of the first sidewall 133 is not parallel to the second sidewall 135. The lower end of the first sidewall 133 extends outward from the upper end of the first sidewall 133 toward the side of the connecting wall 134 away from the second sidewall 135. Thus, when the top cover 130 is opened, the body 131 is tilted in the vertical direction. The pivot end of the pivotal connection between the body 131 and the top wall 110 is positioned lower than the position of the end of the body 131 opposite to the pivot end. In this way, water accumulated on the body 131 flows toward the pivot end of the body 131 in the direction indicated by the arrow above the body 131. At this time, the arrangement of the first sidewall 133 can guide the water flow to the outside of the top hole 112, thereby reducing the amount of water entering the top hole 112.

[0064] In this embodiment, at least a portion of the first sidewall 133 is not parallel to the second sidewall 135. The lower end of the first sidewall 133 extends outward from the upper end of the first sidewall 133 toward the side of the connecting wall 134 away from the second sidewall 135. When the top hole cover 130 is in the open position, the first sidewall 133 can guide water flow to the outside of the top hole 112 to reduce the amount of water entering the top hole 112.

[0065] Optionally, such as Figure 2 and Figure 3 As shown, the first sidewall 133 includes a first wall segment 137 and a second wall segment 138. Both the first wall segment 137 and the second wall segment 138 are flat plate structures. The first wall segment 137 may be parallel to the second sidewall 135. The upper end of the first wall segment 137 is connected to one end of the connecting wall 134. The lower end of the first wall segment 137 is connected to one end of the second wall segment 138. The other end of the second wall segment 138 is located on the side of the first wall segment 137 away from the second sidewall 135. Thus, as... Figure 3 As shown, when the top hole cover 130 is opened, the second wall section 138 can guide water to flow outside the top hole 112, thereby reducing the amount of water entering the top hole 112.

[0066] It is understood that, in embodiments not shown, the connecting wall of the sealing groove can also be rotatably connected to the top wall via a pivot shaft, so that the top cover can rotate.

[0067] Optionally, such as Figure 2 and Figure 3 As shown, the first wall segment 137 is perpendicular to the connecting wall 134. Therefore, the structure of the sealing groove 132 is simple.

[0068] Please continue to refer to this. Figure 2 and Figure 3 The second wall section 138 is inclined to the first wall section 137. The upper end of the second wall section 138 is connected to the lower end of the first wall section 137. This facilitates drainage.

[0069] It is understood that, in embodiments not shown, the second wall segment is parallel to the connecting wall.

[0070] Optionally, such as Figure 2 and Figure 3 As shown, the sealing wall 121 extends upward and protrudes from the cover body. Therefore, when the top cover 130 is in the closed position, the sealing wall 121 can more effectively abut against the sealing strip 150.

[0071] like Figures 1 to 3As shown, with the top structure installed on the container and the top cover 130 in the closed position, the projection of the top wall 110 onto the horizontal plane is rectangular. The outer contour of the projection of the sealing annular structure onto the horizontal plane is also rectangular. At this time, the rectangular edge of the sealing annular structure is parallel to either the width or length direction of the container. The rectangular edge of the top wall 110 is parallel to either the width or length direction of the container. The axial direction of the pivot shaft 140 is parallel to one edge of the rectangular sealing annular structure. Therefore, the structure of the top cover 130 is simple.

[0072] like Figure 2 and Figure 3 As shown, the sealing wall 121 extends in the vertical direction. This simplifies the structure of the support member 120.

[0073] like Figure 2 and Figure 3 As shown, the cover body also includes a frame 111. The frame 111 is constructed as a circumferentially closed annular structure. The support member 120 is connected to the upper surface of the frame 111. As a result, the top wall 110 has high strength at the top hole 112.

[0074] Optionally, the cover body also includes top side beams, top beams, longitudinal beams, and transverse beams. The length direction of the top side beams is perpendicular to the length direction of the top beams. One top side beam, one top beam, another top side beam, and another top beam are connected end to end to form a circumferentially closed rectangular frame. The length direction of the longitudinal beams is parallel to the length direction of the top side beams. The longitudinal beams are located between two top side beams. The ends of the longitudinal beams are connected to the top beams. The length direction of the transverse beams is parallel to the length direction of the top beams. The transverse beams are located between two top transverse beams. The ends of the transverse beams are connected to the top side beams. Therefore, the cover has high strength.

[0075] Optionally, the longitudinal beams and transverse beams are connected to form the frame 111. As a result, the frame 111 has high strength.

[0076] like Figure 2 and Figure 3 As shown, the support member 120 also includes a support connecting wall 122. Both the support connecting wall 122 and the sealing wall 121 are flat plate structures. The support connecting wall 122 is attached to the upper surface of the frame 111 and welded to the upper surface of the frame 111. The support connecting wall 122 and the sealing wall 121 intersect (e.g., perpendicularly). One end of the support connecting wall 122 is connected to the lower end of the sealing wall 121. Therefore, the support member 120 has high strength.

[0077] Furthermore, the supporting connecting wall 122 and the sealing wall 121 form an approximately L-shaped structure. As a result, the structure of the support member 120 is simple.

[0078] Second Implementation Method

[0079] like Figure 4As shown, the first sidewall 233 is a flat plate structure. The first sidewall 233 is inclined to the connecting wall 234. The lower end of the first sidewall 233 is further away from the second sidewall 235 than the upper end of the first sidewall 233. In this way, when the top cover is in the open position, the first sidewall 233 can guide water to flow out of the top hole, thereby reducing the amount of water entering the top hole.

[0080] The other settings of the second embodiment are largely the same as those of the first embodiment, and will not be described in detail here.

[0081] Third Implementation Method

[0082] like Figure 5 As shown, the sealing groove assembly includes a sealing groove member 332 and a rain shield 337. The sealing groove member 332 includes a second sidewall 335 and a connecting wall 334, which are substantially the same as in the first embodiment. The sealing groove member 332 also includes a sidewall section 336. The sidewall section 336 has a flat plate structure. The sidewall section 336 is parallel to the second sidewall 335. The upper end of the sidewall section 336 is connected to one end of the connecting wall 334. The sidewall section 336 is located outside the second sidewall 335. The sidewall section 336 and the second sidewall 335 are spaced apart. The rain shield 337 is connected to the sidewall section 336 to form the first sidewall of the first embodiment. The rain shield 337 extends outward from the sidewall section 336 toward the side of the sidewall section 336 away from the second sidewall 335. Therefore, when the top hole cover is in the open position, the first sidewall can guide water flow to the outside of the top hole, thereby reducing the amount of water entering the top hole.

[0083] Optionally, the rain shield 337 includes a rain-shielding sidewall 338 and a rain-shielding bottom wall 339. The rain-shielding sidewall 338 is attached to and connected to the sidewall segment 336 to form a first wall segment in the first embodiment. The rain-shielding bottom wall 339 is connected to the lower end of the rain-shielding sidewall 338 and extends outward from the rain-shielding sidewall 338 away from the second sidewall 335. The rain-shielding bottom wall 339 forms a second wall segment in the first embodiment. Thus, the structure of the rain shield 337 is simple.

[0084] Furthermore, the rainproof sidewall 338 and the rainproof bottom wall 339 are constructed in an L-shape. As a result, the structure of the rainproof panel 337 is simple.

[0085] The other settings in the third embodiment are largely the same as those in the first embodiment. They will not be described in detail here.

[0086] Fourth Implementation Method

[0087] like Figure 6 As shown, the support only includes the sealing wall 421. The lower end of the sealing wall 421 is attached to and welded to the inner side of the frame 411 near the center of the area enclosed by the frame 411.

[0088] The other settings in the fourth embodiment are largely the same as those in the first embodiment. They will not be described in detail here.

[0089] Fifth Implementation Method

[0090] like Figure 7 As shown, the support only includes the sealing wall 521. The lower end of the sealing wall 521 is connected to the upper surface of the frame 511.

[0091] The other settings in the fifth embodiment are largely the same as those in the first embodiment. They will not be described in detail here.

[0092] This invention also provides a container. The container includes the aforementioned top structure.

[0093] In this embodiment, the container includes the aforementioned top structure and the provision of a first side wall. When the top hole cover is in the open position, the first side wall can guide water flow to the outside of the top hole to reduce the amount of water entering the top hole.
