Abstract
Description
Technical Field
[0001] This utility model relates to the field of material storage equipment technology, and in particular to a box cover structure. Background Technology
[0002] To facilitate installation, maintenance, and storage tank placement, air-cooled material handling boxes generally adopt a split shell structure, consisting of a box body and a lid assembled together. During production and maintenance, before the lid and box body are assembled, the lid is placed separately on the ground, occupying a large area. If multiple air-cooled material handling boxes are installed, a separate storage area for the lids is required.
[0003] In addition, during the air-cooled refrigeration air circulation process of the air-cooled material handling box, the flow direction of the cold air and the air distribution effect are crucial to the refrigeration heat exchange of its internal storage tank, playing a decisive role in the refrigeration speed, refrigeration effect and overall energy consumption of the machine. Utility Model Content
[0004] To address the aforementioned issues, this invention proposes a box cover structure that allows for stacking to reduce space occupation while also serving to distribute cold airflow.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A box cover structure includes a box cover body, the box cover body having a cover with a certain extension length, and support beams fixedly connected to both sides of the top surface of the box cover along the length direction. The support beams include beam bodies extending along the width direction of the box cover body, and each beam body is provided with a guide anti-tipping structure on one side edge opposite to the other support beam.
[0007] The box cover structure can be stacked vertically, so that the lower edge of the upper box cover structure is engaged with the supporting beam of the lower box cover structure.
[0008] Preferably, the guide anti-tilt structure is an outwardly inclined long strip-shaped structure.
[0009] Preferably, the top surface of the lid is a plane.
[0010] Preferably, the main body of the box cover is an insulated cover.
[0011] Preferably, the vertical cross-section of the box cover body is trapezoidal.
[0012] Preferably, two lifting lugs for lifting the box cover body are respectively provided on the two inclined surfaces of the box cover body.
[0013] Preferably, the inside of the box cover has a partition, and the inside of the box cover also has a horizontally arranged air distribution mesh plate. One edge of the air distribution mesh plate is sealed to the partition, and the other three edges of the air distribution mesh plate are sealed to the inner wall of the box cover. The partition and the inner wall of the box cover form a cold air entry channel, and the air distribution mesh plate and the inner wall of the box cover form an air distribution channel.
[0014] The beneficial effects of using this utility model are:
[0015] This box cover structure has supporting beams on both sides of its top width direction. When multiple box cover structures need to be stored, they can be stacked. The lower edge of the upper box cover structure is engaged with the supporting beam of the lower box cover structure. This stacking arrangement of the box cover structure can reduce the space occupied by the box cover storage. When one piece of equipment needs maintenance, the box cover of that equipment can be temporarily placed on top of the box cover of another equipment, reducing the space occupied by the box cover.
[0016] The cover structure of this box is equipped with partitions and air distribution mesh plates inside. These partitions and air distribution mesh plates form an airflow guiding structure, which can evenly distribute the airflow into the box body below. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this technical solution clearer, the following detailed description, in conjunction with specific embodiments, further illustrates this technical solution. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.
[0026] like Figure 1 As shown, this embodiment proposes a lid structure, which is used to cooperate with the box body 20 to form a relatively sealed low-temperature air-cooled box, which is used to store materials at low temperatures through the container.
[0027] Because the cover 10 has an internal air-guiding structure that serves as a channel for the circulation of cold air inside the low-temperature air-cooled box, the cover 10 is designed with a special shape to ensure better cold air guidance as part of the air-guiding structure. In this embodiment, the vertical cross-section of the cover body 11 is trapezoidal.
[0028] During production and maintenance, before the lid 10 and the body 20 are assembled, the lid 10 is placed alone on the ground, occupying a large area. If multiple air-cooled material handling boxes are installed, a separate storage area for the lid 10 is required. To avoid the lid 10 occupying too much space when stored alone, and considering that the low-temperature air-cooled boxes need to be installed relatively densely with small aisles in between, there is no place to put the lid 10 when it is removed for maintenance. In this embodiment, the lid body 11 of the lid 10 is a lid with a certain extension length. Support beams 12 are fixedly connected to both sides of the top surface 111 of the lid 10 along its length. The support beams 12 include beam bodies 121 extending along the width direction of the lid body 11. Each beam body 121 has a guide anti-tilting structure 122 on one side edge opposite to the other support beam 12. The lid structures can be stacked vertically, so that the lower edge of the upper lid structure is engaged with the support beam 12 of the lower lid structure.
[0029] In this embodiment, considering structural strength, the number of stacked layers of the box cover 10 is not limited. If the strength is reliable, multiple box covers 10 can be stacked.
[0030] In order to avoid interference between the top surface 111 of the box cover 10 and the box cover 10 above it after the box covers 10 are stacked, the top surface 111 of the box cover body 11 is a plane in this embodiment.
[0031] In this application, since the cover 10 is used in a low-temperature air-cooled box, in order to avoid rapid heat exchange between the air inside the low-temperature air-cooled box and the external environment, the main body 11 of the cover in this embodiment is an insulated cover.
[0032] Two lifting lugs 13 are respectively provided on the two inclined surfaces 112 of the main body of the box cover 11 for lifting the main body of the box cover 11. The lifting lugs 13 at this position can ensure that the box cover 10 is lifted stably as a whole, and can also prevent the lifting lugs 13 from affecting the vertical stacking of the box cover 10.
[0033] like Figure 2 and Figure 3 As shown, each crossbeam body 121 has a guide anti-tilting structure 122 on one side edge opposite to the other supporting crossbeam 12. In this embodiment, the guide anti-tilting structure 122 is an outwardly inclined long strip-shaped structure. The two supporting crossbeams 12 and the top surface 111 of the box cover body 11 form a "U"-shaped structure. The guide anti-tilting structure 122 has two functions. First, when the two box covers 10 are stacked, the guide anti-tilting structure 122 can act as a guide structure, making it easier for the two box covers 10 to be aligned relative to each other. Second, when the two box covers 10 are stacked, the guide anti-tilting structure 122 can prevent the upper box cover 10 from moving relative to the lower box cover 10, making the placement more stable.
[0034] like Figure 4 As shown, the air guiding structure described above in this embodiment is as follows: the inside of the box cover 10 has a partition 14, and the inside of the box cover 10 also has a horizontally arranged air distribution mesh 16. One edge of the air distribution mesh 16 is sealed to the partition 14, and the other three edges of the air distribution mesh 16 are sealed to the inner wall of the box cover 10. The partition 14 and the inner wall of the box cover 10 form a cold air inlet channel 15, and the air distribution mesh 16 and the inner wall of the box cover 10 form an air distribution channel. Combined with... Figure 5 As shown, after the air inside the box 20 is driven and guided into the cold air inlet channel, the cold air is guided to the mesh of the air distribution plate 16 inside the box cover 10. Then the cold air passes through the mesh of the air distribution plate 16 and enters the main space inside the box 20, where it exchanges heat with the containers and materials stored inside the containers to achieve the effect of low-temperature storage of materials in the low-temperature air-cooled box.
[0035] This box cover structure has supporting beams 12 on both sides of its top width direction. When multiple box cover structures need to be stored, they can be stacked. The lower edge of the upper box cover structure is engaged with the supporting beam 12 of the lower box cover structure. This stacking arrangement of the box cover structure can reduce the space occupied by the box cover 10. When one piece of equipment needs maintenance, the box cover 10 of that equipment can be temporarily placed on top of the box cover 10 of another piece of equipment, reducing the space occupied by the box cover 10.
[0036] The cover structure has an internal partition 14 and an air distribution mesh 16, which form an airflow guiding structure that can evenly distribute the airflow into the lower box 20.
[0037] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the ideas of this technical content. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this patent.
