Description

Technical Field

[0001] The present invention relates to the technical field of containers, and more particularly to an open-top container. Background Art

[0002] An open-top container is a special container with an open top and no fixed roof. Its top is usually covered with a detachable waterproof canvas awning or equipped with a foldable metal frame. Its design feature allows the use of cranes and other equipment to directly and vertically load and unload extra-high, extra-large, irregularly shaped or particularly bulky goods (such as large machinery, engineering equipment, steel, stone, etc.) through the space above the container. At the same time, it retains the side doors of standard containers to facilitate horizontal operations of equipment such as forklifts. The canvas awning on the top can provide protection against rain and dust during transportation. Therefore, it perfectly solves the height restrictions and loading and unloading difficulties in transporting large special goods, while meeting the requirements of standardized ocean shipping. It is an indispensable tool in the field of heavy-lift transportation.

[0003] When using containers to transport dusty powdery materials like pulverized coal, open-top containers with partially retractable roofs are often used to effectively suppress dust dispersion during loading and unloading. By precisely controlling the size of the top opening, the risk of dust can be significantly reduced. However, existing solutions still have significant shortcomings in terms of waterproofing and sealing. For example, the solution disclosed in Publication No. CN111689085A uses a roller-type flexible roof to achieve partial opening and closing. However, a gap exists between the roof and the side walls of the container, making it difficult to prevent rainwater from seeping in, which can easily cause the materials to become damp. Another example is the solution disclosed in Publication No. CN110254981A, which uses a multi-section folding rigid roof to improve sealing. However, when the roof is folded and stowed, rainwater easily accumulates on its surface and drips directly onto the materials inside, also causing them to get wet. Therefore, there is an urgent need to develop an open-top container structure that can reliably block rainwater infiltration when the roof is fully closed or partially open. Summary of the Invention

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0019] Please refer to Figures 1 to 5 An open-top container includes: a container body 1, a top cover 2, a stabilizing frame 3 and several cover mechanisms 4; wherein, the top cover 2 is arranged on the top of the container body 1, and the stabilizing frame 3 is arranged on the top cover 2, which includes several frame windows 31, and the frame windows 31 serve as material inlet. The stabilizing frame 3 is a frame structure welded from square steel, and the frame windows 31 are rectangular structures and are linearly and evenly distributed.

[0020] Several cover mechanisms 4 are correspondingly arranged on the frame windows 31. The number of cover mechanisms 4 is the same as the number of frame windows 31. The frame windows 31 are generally arranged in three and are linearly and evenly distributed on the central axis of the top cover 2, just enough to cover the left, right and middle areas of the container body 1. Each cover mechanism 4 includes: two sealing cover plates 41 and a water retaining assembly 42. The two sealing cover plates 41 are symmetrically hinged on the frame windows 31. When the two sealing cover plates 41 are closed, they completely cover the corresponding frame windows 31 to ensure that the frame windows 31 are completely blocked. A sealing strip 413 in contact with the frame window 31 is provided on the bottom surface of the sealing cover plate 41. The sealing strip 413 is in the form of a rectangular frame and is adapted to the frame window 31. The sealing strip 413 is made of rubber material and is generally 2-4 cm thick. It is not only used to improve the sealing effect of the sealing cover plate 41, but also plays a buffering and shock-absorbing role to avoid rigid contact between the sealing cover plate 41 and the frame window 31 when the sealing cover plate 41 is closed. The top surface of the sealing cover plate 41 is provided with a number of linearly evenly distributed drainage grooves 411. The number of the drainage grooves 411 is specifically set according to the size of the sealing cover plate 41 to ensure that the top surface of the sealing cover plate 41 can be completely covered. A drainage plate 412 is provided between the top cover 2 and the stabilizing frame 3 for draining the water discharged from the drainage groove 411 to the outside of the top cover 2. The drainage plate 412 is provided with an inclined surface, the height of which decreases successively from the sealing cover plate 41 to the top cover 2, and a drainage hole is provided on the side where the top cover 2 is connected to the drainage plate 412, through which rainwater on the drainage plate 412 can be directly discharged to the outside of the container body 1.

[0021] For more details, please refer to Figure 1 and Figure 3The drainage groove 411 is V-shaped, and the width of the drainage groove 411 is shortened from its butt end to the end, while the depth is increased from its butt end to the end. The V-shaped drainage groove 411 can collect rainwater on the surface of the sealing cover plate 41 and automatically discharge the rainwater under the action of gravity, away from the butt joint position of the sealing cover plate 41. Such a design can further improve the drainage effect of the sealing cover plate 41 itself.

[0022] During the process of flipping the sealing cover 41 to open, if rainwater remains on the sealing cover 41, since the sealing cover 41 completely covers the frame window 31, the rainwater retained on its upper side will not flow directly into the frame window 31 from both sides, while the remaining rainwater will be discharged along the drainage groove 411 to the guide plate 412 under the action of gravity. Therefore, the entire opening process can prevent rainwater from flowing into the frame window 31.

[0023] Please refer to Figures 2 to 3 After the two sealing covers 41 are closed, if it rains, rainwater will enter the joint between the two, causing rainwater to easily penetrate into the container, or when the sealing covers 41 are opened, rainwater will flow into the container, both of which will cause the materials in the container to get wet. Therefore, in addition to improving the sealing covers 41, the present invention also provides a water retaining assembly 42 to improve the waterproof performance of the cover mechanism 4. The specific solution is as follows: the water retaining assembly 42 includes a water retaining plate 421, which slides on the top of one of the sealing covers 41. The water retaining plate 421 is used to cover the joint of the two sealing cover plates 41 after closing to prevent external rainwater from entering; the cross-section of the water retaining plate 421 is an isosceles trapezoid, and the two inclined surfaces thereon can respectively drain the rainwater to the sealing cover plates 41 on the corresponding sides to avoid rainwater accumulation. A water retaining strip is provided on the side of the water retaining plate 421 located above the top surface of the sealing cover plate 41. The water retaining strip is used to increase the sealing between the water retaining plate 421 and the top surface of the sealing cover plate 41 to prevent rainwater from entering the joint of the sealing cover plate 41 through the gap between the two.

[0024] After the two sealing covers 41 are closed, the water retaining plate 421 is slid to move to the butt joint of the two sealing covers 41 to isolate the butt joint from the external environment. In rainy weather, rainwater falls directly on the top surface of the sealing cover 41 and flows quickly to the sealing cover 41 under the action of the inclined guide on both sides thereof. When the sealing cover 41 is opened, the water retaining plate is driven to slide away from the butt joint. Since the rainwater on its surface is basically discharged, very little rainwater flows directly out of the water retaining plate 421. Since the butt joint is isolated from the outside, there is also very little rainwater on it. Therefore, when the two sealing covers 41 are opened, no rainwater will drip into the container body 1.

[0025] It can be seen from the above scheme that the container set up by the present invention replaces the traditional integrated opening structure by arranging multiple cover mechanisms 4 on the top cover 2, and can open the frame window 31 in a targeted manner to achieve basic suppression of dust during loading and unloading; and through the improvement of the drainage groove 411 structure of the sealing cover 41 and the coordinated waterproofing of the water baffle 421, when the sealing cover 41 is closed, the water baffle 421 is used to cover the joint of the sealing cover 41, which can directly block the path for rainwater to seep into. At the same time, with the help of the drainage effect of the sealing cover 41 itself, the water on the cover can be quickly drained to prevent rainwater accumulation; and in the opening process, the sliding water baffle 421 can isolate the accumulated water above the joint at the moment of opening the cover to prevent the accumulated water from directly flowing into the frame window 31, so as to ensure moisture-proofing throughout the transportation and loading and unloading dual working conditions.

[0026] Please refer to Figures 6 to 8 , based on the above-mentioned design of the water baffle 421, it is further optimized. The specific solution is as follows: the two ends of the water baffle 421 are slidably connected to the corresponding sealing cover plate 41 through pulleys 422, and a limiting slide groove 423 adapted to the pulley 422 is provided on the sealing cover plate 41. When the pulley 422 rolls to the end of the limiting groove, the water baffle 421 is just above the joint. The setting of the limiting slide groove 423 can quickly position the water baffle 421 and prevent it from detaching from the sealing cover plate 41. Sliding card plates 424 for sliding engagement with adjacent sealing cover plates 41 are fixed at both ends of the water baffle 421. 21 are provided with guide grooves 425 adapted to the sliding card plate 424. After the two sealing cover plates 41 are closed, when the water baffle 421 is driven to slide to the position just above the joint, the sliding card plate 424 first slides in cooperation with the guide groove 425 with which it is initially connected, and then slides into the guide groove 425 on the adjacent sealing cover plate 41, so that the sliding card plate 424 is slidably engaged with the two sealing cover plates 41 at the same time. At this time, the water baffle 421 acts as a sliding locking mechanism, which can vertically lock the closed sealing cover plates 41, thereby avoiding the problem of the sealing cover plates 41 being opened due to road bumps during transportation.

[0027] Please refer to Figures 6 to 8Based on the above-mentioned further improvement of the water baffle 421, it realizes the locking effect of the sealing cover plate 41 in the vertical direction, but it itself is easily loosened in the horizontal direction due to the horizontal sliding connection with the sealing cover plate 41. Therefore, the water baffle assembly 42 is further optimized: the water baffle assembly 42 also includes two locking parts 43 for locking the two ends of the water baffle 421, and the locking part 43 includes a gripping part that slides on the end of the water baffle 421 and a clamping part that cooperates with the gripping part. The holding portion includes a grip rod 431, and a return spring 432 is provided between the grip rod 431 and the water baffle 421. Under the support of the return spring 432, the grip rod 431 is located above the end of the water baffle 421; the clamping portion includes a positioning plate 433 fixed on the frame window 31, and the positioning plate 433 is located close to the docking seam of the sealing cover plate 41, and a docking recess adapted to the sliding end of the grip rod 431 is provided on the positioning plate 433, and a clamping block 434 for clamping the sliding end of the grip rod 431 is sliding on the positioning plate 433, and the bottom of the sliding end of the grip rod 431 and the top of the clamping block 434 are provided with adapted inclined surfaces; a support spring 435 is provided between the clamping block 434 and the positioning plate 433, and a pull rod for pulling the clamping block 434 to slide is provided on the outside of the positioning plate 433.

[0028] After the water retaining plate 421 slides to the joint of the sealing cover plate 41, the gripping rod 431 is just above the joint notch, and then the gripping rod 431 is pressed downward to squeeze the reset spring 432 to contract. When the bottom of the sliding end of the gripping rod 431 contacts the block 434, the squeeze block 434 contracts into the positioning plate 433, and the support spring 435 is squeezed by the squeeze block 434. After the gripping rod 431 slides to the lower end position of the notch, the block 434 separates from the sliding end of the gripping rod 431 and automatically resets with the help of the elastic force of the support spring 435. It extends to the top surface of the sliding end of the grip rod 431, thereby locking the grip rod 431 in the vertical direction, preventing it from moving upward. At this time, the grip rod 431 is locked in both the vertical and horizontal directions. Even if the digital display is greatly bumpy during transportation, the water baffle 421 can remain stable. When opening the sealing cover 41, it is only necessary to pull the pull rod to retract the block 434, and the grip rod 431 automatically moves up and resets under the elastic force of the reset spring 432. After that, the grip rod 431 is driven to drive the water baffle 421 to slide away from the joint.

[0029] Please refer to Figures 6 to 9 Based on the above optimization of the horizontal locking of the water baffle 421, the present invention continues to make improvements. The improvement scheme is: an extrusion groove 436 is provided on the positioning plate 433, and the extrusion groove 436 consists of a straight section and an inclined section. The water baffle 421 is provided with a sliding shaft 437 adapted to the extrusion groove 436.

[0030] When the water baffle 421 slides to the joint of the sealing cover plate 41, the sliding shaft 437 first enters the straight section of the extrusion groove 436. After the sliding card plate 424 slides into the guide groove 425 of the adjacent sealing cover plate 41, the sliding shaft 437 just slides into the inclined section of the extrusion groove 436. At this time, the sliding shaft 437 begins to slide downward along the inclined section and exerts a downward force on the water baffle 421, while the water baffle 421 simultaneously exerts downward pressure on the two sealing cover plates 41, which can generate an extrusion force on the sealing strip 413 at the bottom of the sealing cover plate 41, so that the contact between the sealing strip 413 and the frame window 31 is closer, thereby further improving the sealing effect of the sealing cover plate 41.

[0031] It can be seen from the above scheme that the water-retaining assembly 42 provided in the present invention is not only used to prevent external rainwater from entering the joint of the closed sealing cover plate 41, thereby improving the waterproof effect of the sealing cover plate 41 when closed and opened, but can also be used to lock the sealing cover plate 41 in the vertical direction, thereby improving the stability of the sealing cover plate 41 when closed, and at the same time can also generate extrusion pressure on the sealing strip 413, thereby improving the sealing effect of the sealing cover plate 41.

[0032] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms under the guidance of the present invention, all of which are protected by the present invention.
