Description

Technical Field

[0001] This utility model relates to the field of energy storage container technology, and in particular to an energy storage container with a detachable top structure. Background Technology

[0002] Energy storage containers are integrated energy storage systems that combine various energy storage and energy management devices. Their core components typically include energy storage batteries, battery management systems (BMS), energy conversion systems (such as power electronic converters), and container environmental monitoring systems. These devices are encapsulated within standardized containers to form complete and independent energy storage units. Inside the energy storage container, battery racks are designed to tightly arrange and secure multiple battery modules. This not only provides stable support and fixation for the battery pack, promotes heat dissipation, facilitates the arrangement and connection of battery modules, and ensures battery pack safety, but also simplifies battery pack maintenance and management. Furthermore, these battery racks are usually customized according to the size and shape of the batteries and are made of metal materials such as iron and aluminum to ensure strength and stability. To reduce the workload of battery rack installation, multiple battery racks are often combined into a modular structure, which is then installed inside the energy storage container, thereby reducing the amount of work involved in installing battery racks inside the container.

[0003] Regarding the aforementioned technologies, the inventors discovered that, in order to fully utilize the internal volume of energy storage containers, the height of modular battery racks is often designed to be higher than the height of the side mounting doors. Therefore, mounting holes need to be opened on the top of the energy storage container so that the modular battery racks can be hoisted through the mounting holes and placed into the container by a crane. Afterward, the mounting holes are sealed with covers to prevent rainwater and dust from entering the container. However, the existing connection methods between the covers and the energy storage containers mostly use bolt connections. When using this connection method, it is usually necessary to open through holes on the top of the container. This results in poor sealing between the covers and the container, and rainwater and dust can easily enter the container through the through holes, thereby reducing the effectiveness of the energy storage container. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide an energy storage container with a detachable top structure, which solves the problem of poor sealing and enhances the performance.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: providing an energy storage container with a detachable top structure, comprising: a container body, the top of the container body having a rectangular mounting hole, a cover plate assembly above the rectangular mounting hole, and a sealing assembly, wherein the cover plate assembly is detachably connected to the container body through the sealing assembly, and is suitable for sealing the rectangular mounting hole; The cover plate assembly includes a cover plate body and a rectangular frame. The cover plate body is sealed to the inner cavity of the rectangular frame. The rectangular frame includes four inverted U-shaped steel bars connected end to end. The sealing assembly includes strip blocks respectively disposed within the U-shaped steel, the strip blocks being connected to the top of the container body, and rubber plates one being disposed between the strip blocks and the top of the U-shaped steel. It also includes at least two Z-shaped pressure plates pressing against the top of the U-shaped steel. Each Z-shaped pressure plate includes a Z-shaped pressure plate body, a second rubber plate, a third rubber plate, and a threaded tube with a sealed lower end. The second rubber plate is disposed between the upper horizontal side of the Z-shaped pressure plate body and the upper plane of the U-shaped steel, and the third rubber plate is disposed between the lower horizontal side of the Z-shaped pressure plate body and the top of the container body. The upper end of the threaded tube passes through the top of the container body and is sealed by welding. A bolt connected to the internal threaded hole of the threaded tube passes through the lower horizontal side of the Z-shaped pressure plate body.

[0006] By adopting the above technical solution, in actual operation, the modular battery rack is first hoisted to the designated position using a crane, allowing it to be precisely lowered into the container body through the rectangular mounting holes. After the battery rack is in place, workers first fix the connection between the modular battery rack and the container body to ensure that the battery rack is stable and does not shift inside the container. After the fixing work is completed, the crane is used to hoist the cover plate assembly directly above the rectangular mounting holes to complete the covering action. It should be noted that a rubber sheet has been pre-laid on the top of the strip block. When covering, the U-shaped steel on the sealing component must be engaged with the corresponding strip block. Above, ensure that rubber plate one is in close contact with the inner top wall of the U-shaped steel; next, press the upper horizontal side of the Z-shaped pressure plate onto the top of the U-shaped steel, while placing rubber plate two between the contact surfaces of the two, and placing rubber plate three between the lower horizontal side of the Z-shaped pressure plate and the top of the container body. Then, bolts are used to pass through the lower horizontal side of the Z-shaped pressure plate and rubber plate two in sequence, finally forming a threaded fastening connection with the inner hole of the threaded pipe. During this process, rubber plate one, rubber plate two, and rubber plate three will achieve a tight fit due to external pressure. Through the above structural design, rubber plate one can form an elastic sealing connection between the U-shaped steel and the strip block, while rubber plate three can achieve an elastic seal between the Z-shaped pressure plate and the top of the container body. The double sealing effect can effectively prevent rainwater and dust from entering the interior of the container body through the rectangular installation hole, while preventing rainwater and dust from seeping in from the connection between the threaded pipe and the container body. This completely solves the problem of poor sealing in traditional installation methods and significantly improves the overall performance and durability of the equipment.

[0007] In a preferred embodiment, the present invention can be further configured such that two lifting lugs are respectively connected at intervals to the two long sides of the cover plate assembly.

[0008] By adopting the above technical solution, two lifting lugs are fixed at intervals on the two sides of the cover plate assembly, making it convenient to pass the lifting rope through the lifting lugs and hang it on the hook of the crane. After the crane is started, the cover plate assembly is lifted.

[0009] In a preferred embodiment, the present invention can be further configured such that the cross-section of the cover plate is an inverted V structure.

[0010] By adopting the above technical solution and setting the cover plate body to an inverted V structure, rainwater can flow quickly after falling on the cover plate body, reducing the probability of rainwater seeping into the interior of the container body through the cover plate body.

[0011] In a preferred embodiment, the present invention may be further configured to include an air-cooling mechanism for reducing the internal temperature of the container body; The air-cooling mechanism includes a gas input component and a gas discharge component. The gas input component includes a fan installed on the container body. The air inlet of the fan is connected to a filter screen. A guide shell is provided above the air inlet of the fan to guide the gas below into the inner cavity of the container body. The guide shell is connected to the side of the container body. The gas exhaust assembly includes an exhaust window frame embedded in the end of the container body and louvers disposed in its inner cavity. The top two sides of the louvers are connected to the exhaust window frame by sliding supports, and the lower two sides of the louvers are connected to pneumatic support members. The pneumatic support member includes a pneumatic rod. One end of the pneumatic rod is hinged to a hinge seat one, and the other end is hinged to a hinge seat two. The hinge seat one is connected to the bottom inside the exhaust window frame, and the hinge seat two is connected to the louvers.

[0012] By adopting the above technical solution, after the fan starts, it draws in outside air and blows it into the interior of the container, thereby cooling the battery pack inside. The use of a filter prevents dust from being sucked in by the fan and flowing into the container. The gas carries away the heat from the battery pack, forming hot air, which flows out through the inner cavity of the exhaust window frame, thus dissipating heat from inside the container. In windy weather, pressing the louvers causes the air spring to retract, and the louvers fit snugly against the exhaust window frame, preventing external dust from entering the container through the exhaust window frame, achieving dust prevention.

[0013] In a preferred embodiment, the present invention can be further configured such that a door frame is embedded on one side of the container body, and a door panel is hingedly connected inside the door frame.

[0014] By adopting the above technical solution, after opening the door panel, it is convenient for workers to enter and exit the container body through the inner cavity of the door frame, thus improving the convenience of construction.

[0015] In a preferred embodiment, the present invention can be further configured such that: a supporting frame is connected to the lower surface of the cover plate, the supporting frame includes a longitudinal rod, and a plurality of transverse rods are connected at intervals on both sides of the longitudinal rod. The two ends of the longitudinal rod are connected to the inner wall of the rectangular frame, and the outer ends of the transverse rods are connected to the inner wall of the rectangular frame.

[0016] By adopting the above technical solution, a whole support frame is formed by connecting horizontal bars with several horizontal bars. The support frame is connected to the cover plate body and the rectangular frame body respectively, which enhances the structural strength of the cover plate assembly.

[0017] In summary, this utility model has at least one of the following beneficial technical effects: The Z-shaped pressure plate body and the container body (1) are fastened with bolts, so that the rubber plate one seals the U-shaped steel and the strip block, and the rubber plate three seals the Z-shaped pressure plate body and the top of the container, preventing rainwater and dust from seeping in from the rectangular mounting hole and the threaded pipe connection. This solves the problem of poor sealing between the cover plate assembly (30) and the container body (1) and enhances the performance. Attached Figure Description

[0027] The cover plate 31 has an inverted V-shaped cross-section. By setting the cover plate 31 to an inverted V-shaped structure, rainwater can flow quickly after falling on the cover plate 31, reducing the probability of rainwater seeping into the interior of the container body 1 through the cover plate 31.

[0028] Two lifting lugs 5 are connected at intervals to the two long sides of the cover plate assembly 30. By fixing two lifting lugs 5 at intervals to the two sides of the cover plate assembly 30, it is convenient to pass the lifting rope through the lifting lugs 5 and hang it on the hook of the crane. After the crane is started, the cover plate assembly 30 can be lifted.

[0029] The sealing assembly 40 includes strip blocks 41 respectively disposed within the U-shaped steel 321. The strip blocks 41 are connected to the top of the container body 1. A rubber plate 42 is respectively disposed between the strip blocks 41 and the top of the U-shaped steel 321.

The third rubber plate 433 is disposed between the lower horizontal side of the Z-shaped pressure plate body 431 and the top of the container body 1. The upper end of the threaded tube body 434 passes through the top of the container body 1 and is sealed by welding.

[0030] It also includes an air-cooling mechanism for reducing the temperature inside the container body 1; the air-cooling mechanism includes a gas input assembly 60 and a gas exhaust assembly 70, the gas input assembly 60 includes a fan 61 that passes through the container body 1, the air inlet of the fan 61 is connected to a filter screen 62, and a guide housing 63 is provided above the air inlet of the fan 61 to guide the gas below into the inner cavity of the container body 1, the guide housing 63 is connected to the side of the container body 1; the gas exhaust assembly 70 includes an exhaust window frame 71 embedded at the end of the container body 1 and an exhaust window frame 71 provided thereon. The louver 72 in the inner cavity is connected to the exhaust window frame 71 on both sides of the top via sliding supports. The lower two sides of the louver 72 are connected to pneumatic support members 73. The pneumatic support member 73 includes a gas lift rod 731. One end of the gas lift rod 731 is hinged to a first hinge seat 732, and the other end is hinged to a second hinge seat 733. The gas lift rod 731 is connected to the first hinge seat 732 and the second hinge seat 733 via pins. The first hinge seat 732 is connected to the bottom of the exhaust window frame 71, and the second hinge seat 733 is connected to the louver 72. After the fan 61 is started, it draws in outside air and blows it into the interior of the container body 1, thereby cooling the battery pack inside. The filter 62 prevents dust from being sucked in by the fan 61 and flowing into the interior of the container body 1. The air carries away the heat from the battery pack, forming hot air, which flows out through the inner cavity of the exhaust window frame 71, thus dissipating heat from inside the container body 1. In windy weather, pressing the louvers 72 causes the air spring rod 731 to retract, and the louvers 72 fit snugly against the exhaust window frame 71, preventing external dust from entering the interior of the container body 1 through the exhaust window frame 71, achieving dust prevention.

[0031] A door frame 8 is embedded on one side of the container body 1. A door panel 11 is hinged inside the door frame 8, and the door panel 11 is connected to the door frame 8 by several hinges.

The two ends of the longitudinal rods 91 are connected to the inner wall of the rectangular frame 32, and the outer ends of the transverse rods 92 are connected to the inner wall of the rectangular frame 32. The transverse rods 92 are connected to each other to form an integral support frame 90. The support frame 90 is connected to both the cover plate 31 and the rectangular frame 32, thereby enhancing the structural strength of the cover plate assembly 30.

[0033] The implementation principle of this embodiment is as follows: In actual operation, the modular battery rack is first hoisted to the designated position by a crane, and then accurately lowered into the container body 1 through the rectangular mounting hole 2. After the battery rack is in place, the workers first fix the connection between the modular battery rack and the container body 1 to ensure that the battery rack is stable and does not shift inside the container. After the fixing work is completed, the crane is used to hoist the cover plate assembly 30 to the top of the rectangular mounting hole 2 to complete the covering action. It should be noted that the top of the strip block 41 has been pre-laid with rubber plate 42. When covering, the U-shaped steel 321 on the sealing assembly 40 should be respectively engaged above the corresponding strip block 41, and the rubber plate 42 should be tightly connected to the inner top wall of the U-shaped steel 321. Next, the upper horizontal side of the Z-shaped pressure plate 431 is pressed onto the top of the U-shaped steel 321, while a second rubber plate 432 is placed between the contact surfaces of the two, and a third rubber plate 433 is placed between the lower horizontal side of the Z-shaped pressure plate 431 and the top of the container body 1. Then, bolts are sequentially passed through the lower horizontal side of the Z-shaped pressure plate 431 and the second rubber plate 432, ultimately forming a threaded fastening connection with the inner hole of the threaded pipe 434. During this process, the first rubber plate 42, the second rubber plate 432, and the third rubber plate 433 will achieve a tight fit due to external pressure. Through the above structural design, the first rubber plate 42 allows the U-shaped steel 321 to form an elastic sealing connection with the strip block 41, while the third rubber plate 433 allows the Z-shaped steel 321 to form an elastic sealing connection with the strip block 41. The shaped pressure plate 431 achieves an elastic seal with the top of the container body 1. The double sealing effect can effectively prevent rainwater and dust from entering the container body 1 through the rectangular mounting hole 2, while preventing rainwater and dust from seeping in from the connection between the threaded pipe 434 and the container body 1. This completely solves the problem of poor sealing in traditional installation methods and significantly improves the overall performance and durability of the equipment.
