[0042] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0043] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to the outline of the corresponding component itself; directional terms such as "upper," "lower," "top," "bottom," "horizontal," and "vertical" are defined based on the usage habits of the fuel cell stack body provided in this disclosure. Specifically, refer to... Figure 1 In the diagrams shown, the direction indicated by the Z-arrow is top and apex, and vice versa. Additionally, the X and Y directions refer to the horizontal direction, and the Z-direction refers to the vertical direction. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not indicate sequence or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same or similar elements.

[0044] Reference Figure 1This disclosure provides a leveling device for a fuel cell stack body. This leveling device can be used to adjust the horizontal tilt angle and height of the fuel cell stack body 1 relative to the mounting base surface according to the installation environment, so that the fuel cell stack body 1 always meets the installation requirements on the mounting base surface. It should be noted that the horizontal tilt angle in this disclosure refers to the angle between a reference surface of the fuel cell stack body 1 and the mounting base surface in the X, Y, or Z directions. This reference surface can be, for example, the bottom or side surface of the fuel cell stack body 1. The mounting base surface can be a sea surface or a road surface; this disclosure does not limit this. Furthermore, the mounting base surface can be located in the XY plane, the YZ plane, or the XZ plane; this disclosure does not limit this. In the embodiments provided in this disclosure, the description is based on the example of the mounting base surface being located in the XY plane. The leveling device may include a detection unit 2, a control unit, and an adjustment unit 3. The detection unit 2 can be used to analyze the installation environment and fuel cell characteristics, and detect the current values ​​of the horizontal tilt angle and height of the fuel cell body 1. In this disclosure, fuel cell characteristics refer to fuel cell quality information, fuel cell life value dynamic information, and SOH (State of Health), etc., to improve the versatility and applicability of the adjustment device. The control unit can be connected to the detection unit 2 and used to determine the adjustment values ​​of the horizontal tilt angle and height of the fuel cell body 1 based on the detection signals of the detection unit 2, so as to ensure the calculation accuracy of the required adjustment angle and height of the fuel cell body 1. The adjustment unit 3 can include multiple support rods, which extend vertically and are parallel to each other, supporting the bottom of the fuel cell body 1. The control unit can control the multiple support rods individually, so as to flexibly adjust the height of each support rod according to actual needs, so that the fuel cell body 1 can maintain a horizontal state and be located at a preset height, i.e. Figure 1 The state shown allows it to adapt to different mounting surfaces and environmental conditions. It should be noted that the preset height in this disclosure refers to a fixed position selected by the fuel cell stack body 1 according to installation and operational needs. When the support height of one or more support rods precisely matches the preset height for the fuel cell stack body 1, only the support height of the remaining support rods needs to be adjusted. This ensures that the fuel cell stack body 1 remains horizontal while also meeting its height requirements.

[0045] Through the above technical solution, the control unit and detection unit 2 analyze the installation environment and characteristics of the battery stack body 1 in real time, and monitor the current values ​​of the horizontal tilt angle and height of the battery stack body 1 in real time. The adjustment unit 3 automatically adjusts the preset horizontal tilt angle and height of the battery stack body 1 in real time, so that the battery stack body 1 can adapt to different installation base surfaces and environmental conditions. This effectively improves the stability of the battery stack body 1 during operation and installation, reduces the risk of performance degradation or failure caused by tilting, and avoids frequent and unnecessary adjustments to the battery stack body 1, preventing problems such as battery stack instability, performance degradation or failure caused by adjustments.

[0046] Furthermore, the installation environment may include the levelness and slope of the mounting base surface. Levelness refers to the flatness of the mounting base surface within the XY plane, YZ plane, or XZ plane. Slope refers to the degree of inclination of the mounting base surface relative to the XY plane, YZ plane, or XZ plane. Detection unit 2 can be configured to determine preset values ​​for the horizontal tilt angle and height of the fuel cell stack body 1 based on the installation environment and fuel cell stack characteristics. Control unit 2 can be configured to determine adjustment values ​​based on the preset values. Thus, detection unit 2 enables the leveling device to monitor and evaluate the horizontal tilt angle and height of the fuel cell stack body in real time. By analyzing the characteristics of the installation environment and the design parameters of the fuel cell stack body 1, detection unit 2 can determine an ideal preset value for the horizontal tilt angle and height. Correspondingly, control unit 2 can receive data from detection unit 2 and calculate the adjustment value based on the preset value. In the embodiments provided in this disclosure, the preset value can be a specific numerical value, such as 5°, or a range of values, such as 3°~7°. This disclosure does not limit this value to enable corresponding adjustments to the fuel cell stack body 1 under different operating conditions. When the tilt angle of the battery stack body 1 exceeds the preset value, the control unit will automatically activate the adjustment unit 3 to adjust the tilt angle of the battery stack body 1, ensuring that the battery stack body 1 returns to the preset working state. This effectively avoids frequent adjustments caused by small tilts of the battery stack body 1, thereby helping to prevent instability and repeated shaking of the battery stack body 1, and effectively improving the overall operating efficiency and safety of the battery stack.

[0047] According to some embodiments provided in this disclosure, the control unit may include a first expert controller and a second expert controller. In the embodiments provided in this disclosure, the first expert controller and the second expert controller may each be composed of an expert control system (ECS). The first expert controller can be used to determine an adjustment value based on current values ​​to drive the adjustment unit 3. That is, the first expert controller can receive the current values ​​of the horizontal tilt angle and height of the fuel cell stack body 1 in real time, calculate the adjustment value of the fuel cell stack body 1 based on the difference between these current values ​​and preset values, and generate corresponding adjustment commands to adjust the support rods, thereby ensuring that the fuel cell stack body 1 returns to a preset working state. The second expert controller can be used to determine the adjustment value based on fuel cell stack characteristics and the installation environment to drive the adjustment unit 3. That is, the second expert controller is used to receive analysis data from the detection unit 2 on the installation environment and the characteristics and design parameters of the fuel cell stack, and determine the appropriate support rods and their adjustment values ​​based on the analysis data, so that the corresponding support rods can be adjusted accordingly. In the embodiments provided in this disclosure, the first expert controller and the second expert controller can work independently, but the outputs of the first expert controller and the second expert controller can be integrated to select the optimal adjustment value. For example, the output of one controller can be selected based on priority, or the outputs of the two controllers can be weighted and averaged to obtain a more balanced adjustment command. In the embodiments provided in this disclosure, the detection unit 2 can be configured with a feedback mechanism, which can be the tilt sensor mentioned below, to monitor the effect of the adjustment unit 3 on the fuel cell stack body 1 in real time. The feedback mechanism can feed back the results to the two controllers, thereby facilitating real-time monitoring and dynamic adjustment and optimization of the fuel cell stack body 1. This design can effectively realize a flexible and precise adjustment strategy for the fuel cell stack body 1, ensuring that the fuel cell stack body 1 maintains stable and efficient operation in complex working environments, improving the response speed of the leveling device, and enhancing its adaptability and intelligence level.

[0048] Reference Figure 1 The number of support rods can be at least two, and the two support rods are supported one-to-one at the two apex corners of the bottom surface of the fuel cell stack 1. In one embodiment, referring to... Figure 1The number of support rods can be four, and the four support rods can be positioned one-to-one at the four apex corners of the bottom surface of the fuel cell stack body 1 to effectively distribute the weight of the fuel cell stack body 1 and reduce deformation or damage caused by excessive local stress. At the same time, the four support rods can be constructed as a relatively stable support frame, enhancing the stability of the fuel cell stack body 1 and reducing the risk of tilting or tipping over. For example, when the installation base is a slope or uneven ground, the support height of each support rod can be independently adjusted to achieve precise horizontal adjustment of the fuel cell stack body 1 on slopes or uneven ground, ensuring that the working performance of the fuel cell stack body 1 is not affected. It should be noted that this disclosure does not limit the number of support rods, as long as the adjustment and support needs are met. The arrangement can be based on the specific structure of the fuel cell stack body 1. For example, when the bottom surface of the fuel cell stack body 1 is triangular, the number of support rods can be three, and the three support rods can be positioned one-to-one at the three apex corners of the bottom of the fuel cell stack body 1.

[0049] Reference Figure 1 The support rod can be constructed as a telescopic rod 31 capable of extending and retracting vertically to adjust the support height of the fuel cell stack body 1. When the adjustment unit includes the first drive component mentioned below, the telescopic rod 31 is electrically connected to the first drive component, which can be connected to a control unit, for example, via a signal connection. This allows the telescopic rod 31 to quickly adjust its support height according to adjustment needs, adapting to different ground conditions and achieving precise horizontal adjustment of the fuel cell stack body 1. This prevents the fuel cell stack body 1 from tilting or tipping over due to improper support from the telescopic rod 31. Furthermore, the design of the telescopic rod 31 makes height adjustment more convenient, improves adjustment efficiency, and reduces the complexity of adjustment and the labor requirements.

[0050] Reference Figure 1 The adjustment unit 3 may also include a support base 32 that fits against the mounting base surface to effectively distribute the load of the fuel cell stack body 1, enhance the stability of the fuel cell stack body 1 in various environments, and reduce the risk of tilting or tipping over. One end of the telescopic rod 31 can be fixedly connected to the fuel cell stack body 1, and the other end of the telescopic rod 31 can be slidably connected to the support base 32 in the horizontal direction. When the mounting base surface deforms or settles, the sliding design allows the telescopic rod 31 to adjust the installation position of the fuel cell stack body 1 appropriately in the horizontal direction. At the same time, it can also ensure the accurate positioning of the fuel cell stack body 1 during installation, reducing the installation difficulty. In addition, when maintenance or repair of the fuel cell stack body 1 is required, the sliding connection makes adjusting and moving the fuel cell stack body 1 more convenient, saving time and manpower.

[0051] Reference Figure 1 and Figure 2The telescopic rod 31 may include a first rod 311 and a second rod 312. The top end of the first rod 311 can be supported at the bottom of the fuel cell stack body 1, and the top end of the second rod 312 can be coaxially sleeved on the outside of the first rod 311, with the bottom end of the second rod 312 supporting the top surface of the support base 32. This design effectively enhances the strength of the telescopic rod 31 itself and the stability of its connection with other components, reducing the risk of swaying or tilting caused by external forces and ensuring safety during the adjustment and support of the fuel cell stack body 1. The adjustment unit 3 may include a first driving component, such as a drive motor. The output shaft of the first driving component can be connected to one of the first rod 311 and the second rod 312, for example, to the first rod 311, so that the first rod 311 can reciprocate vertically relative to the second rod 312, thereby achieving vertical extension or retraction. This allows for rapid and precise adjustment of the height of the fuel cell stack body 1 to meet the needs of different working scenarios. Furthermore, since the first drive component is connected to the control unit, it not only realizes the automatic adjustment of the support height of the telescopic rod 31, improving operating efficiency and control height, but also effectively prevents the stack body 1 from tilting or overturning due to improper support, thus enhancing overall safety.

[0052] Reference Figure 1 and Figure 2 The adjustment unit 3 may further include a guide rail 33, a slider 34, and a second drive component. The guide rail 33 extends horizontally and is fixedly installed on the side of the support base 32 opposite to the mounting surface, providing stable support for the support rod and slider 34, effectively reducing the swaying of the slider 34 during movement and improving the overall structural stability. The bottom end of the slider 34 can be slidably connected to the guide rail 33 horizontally, and the top end of the slider 34 can be fixedly connected to the telescopic rod 31, allowing adjustment at different positions as the telescopic rod 31 moves along the slider 34. This adapts to different working environments and needs, improving the operational flexibility of the adjustment device. The output end of the second drive component (not shown) can be connected to the slider 34 to drive the slider 34 to reciprocate horizontally relative to the guide rail 33. Through the control of the second drive component, precise movement of the slider 34 can be achieved, ensuring accurate positioning of the fuel cell stack body 1 during installation and reducing errors. (Refer to...) Figure 2 In the embodiments provided in this disclosure, the guide rail 33 can be integrally formed with the support base 32 to further improve the overall effect of the leveling device and the stability of the slider 34 driving the fuel cell body 1 to move.

[0053] Furthermore, in the embodiments provided in this disclosure, the second driving component may include a cylinder mounted on the support base 32 and a piston rod capable of extending and retracting within the cylinder. A slide bar 34 may be connected to the piston rod and driven by the piston rod to reciprocate horizontally along the guide rail 33. This allows for smooth reciprocating movement of the piston rod on the guide rail 33, thereby adjusting the position of the slide bar 34. This enables the support rod to support the fuel cell stack body 1 at different horizontal positions, ensuring the stability and flexibility of the horizontal position adjustment of the fuel cell stack body 1. The specific working principles of the piston rod and cylinder are well known to those skilled in the art and will not be elaborated upon here.

[0054] Reference Figure 1 The detection unit 2 may include a tilt sensor 21 embedded inside the end plate of the fuel cell stack body 1. In the embodiments provided in this disclosure, the tilt sensor 21 may be, but is not limited to, a gravity-type, liquid pendulum-type, laser-type, etc., such as a gyroscope or gravimeter, to measure the horizontal tilt angle of the fuel cell stack body 1 in real time and to provide timely feedback on the working status of the fuel cell stack body. The control unit may include a data transmission module, which may be the first expert controller and the second expert controller mentioned above, or one of them. The data transmission module may be connected to the tilt sensor 21 to receive the angle signal detected by the tilt sensor 21 and to accurately calculate the required adjustment angle. When the tilt angle exceeds the set range, the data transmission module transmits an electrical signal to the first drive motor mentioned above and starts the first drive motor to drive the corresponding support rod to adjust to the appropriate support height so that the fuel cell stack body 1 always remains horizontal. In addition, by embedding the tilt sensor 21 inside the end plate, external space can be saved, installation complexity can be reduced, and the overall effect of the leveling device can be improved.

[0055] Reference Figure 1 The detection unit 2 in this disclosure may further include a laser level 22 and a camera (not shown in the figure). The laser level 22 can be set on one side of the fuel cell stack body 1 in the horizontal direction to emit a horizontal laser beam, providing a clear reference line and making the measurement of the tilt angle more accurate. The camera can collect the horizontal laser beam, and the camera can be configured to send an electrical signal to the control unit when an angle is observed between the fuel cell stack body 1 and the horizontal laser beam, ensuring the continuity and timeliness of the monitoring process. Specifically, after receiving the signal, the control unit can perform data analysis to calculate the tilt angle and tilt direction of the fuel cell stack body 1, so as to adjust the support rods accordingly. In the embodiments provided in this disclosure, four support rods can be driven to extend or retract to the same height simultaneously to adjust the setting height of the fuel cell stack body 1 in the vertical direction.

[0056] Reference Figure 3 and Figure 4Accordingly, this disclosure also provides a leveling method for the fuel cell stack body. This adjustment method can be applied to the leveling device provided in this disclosure. The leveling method includes step S200, analyzing the installation environment and fuel cell stack characteristics of the fuel cell stack body 1, and detecting the current values ​​of the horizontal tilt angle and height of the fuel cell stack body 1. Before step S200, the method may further include step S100, setting the fuel cell stack body 1 on the mounting base surface using the adjustment device. When the bottom contour of the fuel cell stack body 1 is quadrilateral, the number of support rods can be four, with the four support rods respectively supporting the four apex corners of the bottom surface of the fuel cell stack body 1. After step S200, the method further includes step S300, determining the adjustment values ​​of the horizontal tilt angle and height of the fuel cell stack body 1 based on the installation environment, fuel cell stack characteristics, and current values. In this step, the control unit can calculate the required adjustment angle of the fuel cell stack body 1 and the required adjustment of the support height of each support rod, i.e., the adjustment value, based on the preset values ​​of the fuel cell stack body 1. Following step S300, step S400 is further included, where multiple support rods are controlled according to the adjustment value to adjust the horizontal tilt angle of the fuel cell stack body 1. The control unit individually controls multiple support rods located at the bottom of the fuel cell stack body 1 to adjust its horizontal tilt angle. Following step S400, step S500 is further included, where the detection unit 2 feeds back the adjusted position and angle to the control unit in real time to determine whether the fuel cell stack body 1 meets the placement requirements, i.e., whether the current value of the fuel cell stack body 1 meets the preset value. When the fuel cell stack body 1 meets the placement requirements, the adjustment is considered complete; otherwise, steps S300-S500 are repeated. This leveling method has all the beneficial effects of the aforementioned leveling device, which will not be elaborated further here. Furthermore, the specific operation process of the leveling method provided in this disclosure can be completed using the aforementioned leveling device. To avoid redundancy, please refer to the relevant sections above for specific operation processes and details.

Furthermore, the battery stack may possess all the beneficial effects of the leveling device and leveling method provided in this disclosure, which will not be elaborated further here.
