Description

Technical Field

[0001] This utility model relates to the field of flow battery technology, and in particular to a battery stack transfer device. Background Technology

[0002] A flow battery is a device that directly converts the chemical energy of raw materials into electrical energy through an electrochemical reaction. Compared to traditional heat engines, it has a higher energy conversion efficiency and produces almost no pollutants. In recent years, flow batteries, as a highly efficient and clean energy source, have been widely used in portable electronic devices, industrial power supply, home energy storage, and vehicle propulsion. A flow battery stack (or simply stack) is an energy storage module composed of multiple flow battery cells (single cells) connected in series or parallel, possessing specific voltage, current, and capacity output. Currently, commonly used box-type flow battery cabinets, as an integrated energy storage unit, typically contain multiple flow battery stacks. These stacks are connected in series or parallel to form a complete energy storage system to meet the needs of different application scenarios.

[0003] However, in the application of box-type flow battery cabinets, the limited space inside and outside the cabinet makes the transfer of the battery stacks quite difficult. In the existing technology, when maintenance or replacement of the battery stack is required, operators usually need to lift the battery stack to transfer it. The transfer operation is cumbersome and labor-intensive, which is not conducive to improving work efficiency and may also affect the safety and accuracy of the transfer operation.

[0004] Therefore, there is an urgent need to propose a fuel cell stack transfer device to solve the above-mentioned technical problems. Utility Model Content

[0010] Wherein, the first direction and the second direction are perpendicular to each other.

[0011] In some embodiments, a first sliding assembly is provided between the base and the mounting substrate. The first sliding assembly includes a first slide rail and a first sliding member.

[0014] In some embodiments, each of the first slide rails is provided with a limiting component at a first end along the second direction and a fixing component at a second end; the limiting component includes a stop portion disposed on an end plate at the first end, the stop portion being used to stop the corresponding first sliding member and the sub-base; the fixing component includes a connecting portion and a pressing portion, the connecting portion being detachably connected to the first slide rail, and the pressing portion being connected through the connecting portion and capable of pressing against the corresponding sub-base.

[0015] In some embodiments, the limiting component further includes a buffer member, which is sleeved outside the stop portion.

[0016] In some embodiments, a reinforcing rib is connected between the two first slide rails.

[0017] In some embodiments, a second sliding assembly is provided between the tray and the bracket. The second sliding assembly includes a second slide rail and a second sliding member. The second slide rail is fixedly connected to the top of the bracket. Both the second slide rail and the second sliding member extend along the first direction. The second sliding member is slidably connected to the second slide rail along the first direction. The tray is fixedly connected to the second sliding member.

[0018] In some embodiments, two second sliding components are provided, and the two second sliding components are spaced apart along the second direction. The opposite ends of the tray along the second direction are respectively fixedly connected to the corresponding second sliding components.

[0019] In some embodiments, the pallet is fixed with second pull rings at opposite ends along the first direction, and the two second pull rings are arranged opposite each other along the first direction.

Furthermore, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0047] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0048] like Figures 1 to 7 As shown, this embodiment provides a battery stack transfer device, including multiple sets of battery stack transfer mechanisms 100. The multiple sets of battery stack transfer mechanisms 100 are installed on a mounting base plate (not shown in the figure) inside the battery cabinet, and the multiple sets of battery stack transfer mechanisms 100 are spaced apart along a first direction.

[0049] Each stack transfer mechanism 100 includes a bracket assembly 1 and a tray 2.

[0050] The bracket assembly 1 includes a base 11 and a plurality of brackets 12. The base 11 is movably connected to the mounting base along a second direction, and the plurality of brackets 12 are fixedly spaced and fixed to the base 11 along the second direction. The trays 2 are arranged in a one-to-one correspondence with the brackets 12. Each tray 2 is movably connected to the corresponding bracket 12 along a first direction, and each tray 2 is used to fix a single fuel cell stack. The gap between two adjacent fuel cell stack transfer mechanisms 100 along the first direction can accommodate the trays 2.

[0051] The first direction and the second direction are perpendicular to each other. Specifically, the first direction can be the horizontal direction of the battery cabinet, and the second direction can be the vertical direction of the battery cabinet.

[0052] In practice, when a single battery stack on a tray 2 needs maintenance or replacement, the tray 2 can be moved relative to its corresponding bracket 12 along the first direction until the tray 2 moves into the gap between two adjacent battery stack transfer mechanisms 100 along the first direction. At this point, the single battery stack on the tray 2 is separated from the other single battery stacks, allowing maintenance to be performed on the single battery stack on the tray 2. Alternatively, the single battery stack can be transferred to other mobile transfer tools (such as a mobile trolley that can dock with the tray 2) for replacement. After the maintenance or replacement of the single battery stack is completed, the tray 2 can be moved back to its original position. In addition, the bracket assembly 1 can move along the second direction, and the tray 2 can move together with the bracket assembly 1, allowing all single battery stacks in a set of battery stack transfer mechanisms 100 to move as a whole along the second direction. For example, when it is necessary to perform overall maintenance on all single battery stacks and the bracket assembly 1, the bracket assembly 1 can be pulled out of the battery cabinet along the second direction. After the maintenance is completed, the bracket assembly 1 can be moved back to its original position inside the cabinet.

[0053] The fuel cell stack transfer device provided in this embodiment significantly simplifies the maintenance and replacement process of fuel cell stacks through the movable design of the pallet 2 along the first direction and the bracket assembly 1 along the second direction. Individual fuel cell stacks can be transferred without the need for traditional hoisting methods, greatly reducing the complexity and labor intensity of the operation. Simultaneously, the bidirectional mobility of the pallet 2 and bracket assembly 1 enables flexible transfer of individual fuel cell stacks and overall removal for inspection, improving the convenience and safety of fuel cell stack maintenance operations, and further enhancing operational efficiency and the overall reliability of the system.

[0054] For example, this embodiment provides two sets of fuel cell stack transfer mechanisms 100, each set including five trays 2. However, it is not limited to this. For example, in other embodiments, the number of fuel cell stack transfer mechanisms 100 can be set to three or four sets, etc.; each set of fuel cell stack transfer mechanisms 100 can also include six or seven trays 2, that is, each set of fuel cell stack transfer mechanisms 100 can be extended or shortened in a modular manner, depending on the actual situation.

[0055] like Figure 2 and Figure 3 As shown, in some embodiments, a first sliding assembly 3 is provided between the base 11 and the mounting substrate. The first sliding assembly 3 includes a first slide rail 31 and a first sliding member 32. The first slide rail 31 is fixedly connected to the mounting substrate. Both the first slide rail 31 and the first sliding member 32 extend along a second direction. The first sliding member 32 is slidably connected to the first slide rail 31 along the second direction. The base 11 is fixedly connected to the first sliding member 32. In this way, the sliding of the first sliding member 32 relative to the first slide rail 31 can drive the base 11, that is, the bracket assembly 1, to move together.

[0056] With this configuration, the bracket assembly 1 is slidably connected to the mounting base plate. The sliding connection structure ensures stability during movement, and the sliding structure has good guiding performance, which helps to improve the safety and reliability of the entire fuel cell stack transfer device.

[0057] like Figure 6 and Figure 7 As shown, in some embodiments, two first sliding components 3 are provided, and the two first sliding components 3 are spaced apart along a first direction. The base 11 includes two separately arranged sub-bases 111, each sub-base 111 is fixedly connected to a corresponding first sliding member 32, and each bracket 12 is fixedly mounted on its corresponding sub-base 111 at its opposite ends along the first direction. Optionally, the first slide rail 31 is a cuboid track, and the cross-sectional shape of the first sliding member 32 is U-shaped.

[0058] Compared to the overall design, this split-part design can significantly reduce the amount of material used and lower manufacturing costs while ensuring sliding stability and support strength. Secondly, the split sliding design can reduce the overall weight of the structure and further reduce the frictional resistance during sliding, making the base 11 move more smoothly in the second direction.

[0059] Optionally, a reinforcing rib 7 is connected between the two first slide rails 31. The reinforcing rib 7 forms additional support between the two first slide rails 31, which helps to improve the overall structural strength and deformation resistance of the two first sliding components 3.

[0060] like Figures 2-5 As shown, in some embodiments, two brackets 12 at opposite ends of the base 11 along the second direction are respectively fixed with first pull rings 4. The two first pull rings 4 are arranged opposite each other along the second direction. The first pull rings 4 are used to install traction ropes so that the bracket assembly 1 can reciprocate along the second direction.

[0061] With this setup, users can easily pull the bracket assembly 1 using the two first pull rings 4 without having to adjust the position of the equipment or personnel multiple times, which helps to improve operational flexibility.

[0062] Correspondingly, the tray 2 and the bracket 12 can also be movably connected through a sliding connection structure.

[0063] like Figure 6 and Figure 7 As shown, in some embodiments, a second sliding assembly 8 is provided between the tray 2 and the bracket 12. The second sliding assembly 8 includes a second slide rail 81 and a second sliding member 82. The second slide rail 81 is fixedly connected to the top of the bracket 12. Both the second slide rail 81 and the second sliding member 82 extend along a first direction. The second sliding member 82 is slidably connected to the second slide rail 81 along the first direction. The tray 2 is fixedly connected to the second sliding member 82. Thus, the sliding of the second sliding member 82 relative to the second slide rail 81 can drive the tray 2 to move together.

[0064] Furthermore, such as Figure 6 and Figure 7 As shown, in some embodiments, two second sliding components 8 are provided, and the two second sliding components 8 are spaced apart along the second direction. The opposite ends of the tray 2 along the second direction are respectively fixedly connected to the corresponding second sliding component 82. This arrangement can save materials and reduce manufacturing costs while ensuring the stability of the movement of the tray 2.

[0065] like Figure 6 and Figure 7As shown, in some embodiments, second pull rings 9 are fixed at opposite ends of the pallet 2 along the first direction. The two second pull rings 9 are arranged opposite each other along the first direction. The second pull rings 9 are used to install traction ropes so that the pallet 2 can reciprocate relative to the bracket 12 along the first direction. Users can conveniently pull the pallet 2 using the two second pull rings 9, which provides greater operational flexibility.

[0066] Of course, in other embodiments, the bracket assembly 1 and the mounting base plate, and the tray 2 and the bracket 12 can also be movably connected in other ways, such as by setting rollers and rails, and moving them by rolling connection, which will not be described in detail here.

[0067] like Figure 3 and Figure 5 As shown, in some embodiments, each first slide rail 31 is provided with a limiting component 5 at its first end along the second direction and a fixing component 6 at its second end.

[0068] The limiting component 5 includes a stop portion 51 disposed on the end plate at the first end, the stop portion 51 being used to stop the corresponding first sliding member 32 and sub-base 111. The fixing component 6 includes a connecting portion 61 and a pressing portion 62, the connecting portion 61 being detachably connected to the first slide rail 31, and the pressing portion 62 being connected through the connecting portion 61 and capable of pressing against the corresponding sub-base 111.

[0069] When a complete overhaul of a set of battery stack transfer mechanisms 100 is required, first remove the fixing component 6, and then pull the bracket assembly 1 out of the battery cabinet along the second direction for overhaul. During this process, the bracket assembly 1 moves from the first end to the second end of the first slide rail 31. After overhaul, the bracket assembly 1 is reversed and reset. The reverse reset movement path is from the second end to the first end of the first slide rail 31. During reverse reset, the stop part 51 in the limiting component 5 can stop the first sliding member 32 and the sub-base 111, preventing excessive movement of the bracket assembly 1. After the bracket assembly 1 is reversed and reset, the fixing component 6 is installed at the second end of the first slide rail 31, so that the pressing part 62 presses against the sub-base 111. In other words, the fixing component 6 stabilizes the bracket assembly 1, preventing unnecessary displacement.

[0070] like Figure 5 As shown, in some embodiments, the limiting component 5 further includes a buffer 52, which is sleeved on the outside of the stop portion 51.

[0071] By providing a buffer 52, the bracket assembly 1 can be cushioned when it moves to the stop 51, thus avoiding direct collision between the bracket assembly 1 and the stop 51, reducing impact force and minimizing component wear.

[0072] Optionally, the buffer 52 can be made of materials such as rubber or silicone, without specific limitations.

[0073] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
