Technical Field

[0001] This invention relates to the field of auxiliary technology for vanadium redox flow battery equipment, specifically to a field installation and replacement device for vanadium redox flow battery stacks. Background Technology

[0002] Vanadium redox flow batteries, as a high-efficiency, safe and long-life energy storage device, have been widely used in new energy power generation, grid peak shaving and distributed energy. The vanadium redox flow battery stack is the core component of the vanadium redox flow battery, and its weight is usually large. A single stack can weigh hundreds of kilograms or even several tons.

[0003] Currently, when vanadium redox flow battery stacks need to be moved and replaced at construction sites, the complex environment often lacks specialized handling and replacement equipment. The current practice relies mainly on manual labor combined with ordinary lifting equipment. However, this manual operation presents several challenges. First, it's difficult to precisely control the stack's posture and position, increasing the risk of collisions with surrounding equipment and causing damage. This not only affects the normal operation of the vanadium redox flow battery but also increases maintenance costs. Second, ordinary lifting equipment lacks flexibility at construction sites, making it difficult to access and operate in confined spaces. This results in low efficiency in stack handling and replacement, delaying construction progress. Furthermore, manual handling and replacement involves high labor intensity and poses safety hazards, increasing the risk of accidents.

[0004] Therefore, we propose a field installation and replacement device for vanadium redox flow battery stacks to address the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a field installation and replacement device for vanadium redox flow battery stacks, in order to solve the problems mentioned in the background art, which are that existing vanadium redox flow battery stacks mainly rely on manual labor in conjunction with ordinary lifting equipment for operation. This makes it difficult to enter and carry out operations in some narrow construction areas, resulting in low efficiency in the handling and replacement of the stacks. At the same time, the manual handling and replacement process is labor-intensive and poses certain safety hazards.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a field installation and replacement device for a vanadium redox flow battery stack, comprising a movable overall frame for enabling the entire device to move on the construction site, a lifting mechanism for moving the vanadium redox flow battery stack by lifting on one outer surface of the overall frame, the lifting mechanism comprising a movable support and a drive assembly, a lifting platform slidably connected inside the overall frame, an electric conveying mechanism for horizontally pushing the vanadium redox flow battery stack at the top of the movable support, and two lifting mechanism mounting plates fixedly connected to one outer surface of the overall frame.

[0007] Preferably, the outer surface of the movable support is fixedly connected to the drive assembly, and the drive assembly is used to drive the lifting platform to move along the height direction of the movable support.

[0009] Preferably, the drive assembly includes a lifting motor, a lifting lead screw, and a lead screw nut. The lifting motor is fixedly installed at the bottom of the overall frame by screws, and one end of the lifting lead screw is fixedly connected to the output shaft of the lifting motor.

[0010] Preferably, the other end of the lifting screw is rotatably connected to the top of the overall frame, the inner wall of the screw nut is threadedly connected to the outer surface of the lifting screw, and the outer surface of the screw nut is fixedly connected to the outer surface of the lifting platform.

[0011] Preferably, the inner wall of the lifting mechanism is fixedly connected to a linear guide rail extending along its height direction, and the outer surface of the lifting platform is fixedly connected to a guide rail slider, the outer surface of the guide rail slider being slidably connected to the inner wall of the linear guide rail.

[0012] Preferably, the electric transmission mechanism includes an electric transmission motor, the output shaft of which is fixedly fitted with a motor drive synchronous pulley, and the electric transmission motor is fixedly mounted on one side of the outer surface of the lifting platform by screws.

[0013] Preferably, the inner wall of the lifting platform is rotatably connected to multiple load-bearing wheels, and the outer surface of the lifting platform is rotatably connected to roller driven synchronous pulleys on both sides near one edge.

[0015] Preferably, the outer surface of one of the motor driven synchronous pulleys is coupled to the outer surface of the motor driving synchronous pulley, and the outer surfaces of the other two motor driven synchronous pulleys are respectively coupled to the outer surfaces of two roller driven synchronous pulleys.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This device, with its overall frame and casters, enables handling and replacement in various complex indoor and outdoor environments, ensuring equipment flexibility. Simultaneously, the lifting motor and electric transmission motor are electrically driven throughout the lifting and transmission process, reducing manual handling and lowering the labor intensity of handling hundreds of kilograms of battery stacks. This solves the problem that existing vanadium redox flow battery stacks rely primarily on manual labor with ordinary lifting equipment, making it difficult to access and operate in confined spaces, resulting in low efficiency in handling and replacement. Furthermore, manual handling and replacement involve high labor intensity and pose certain safety hazards.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-6 This invention provides a technical solution: a field installation and replacement device for a vanadium redox flow battery stack, comprising a movable overall frame 1 for enabling the entire device to move on the construction site; a lifting mechanism 2 for moving the vanadium redox flow battery stack by lifting on one outer surface of the overall frame 1; the lifting mechanism 2 includes a moving bracket and a drive assembly; a lifting platform is slidably connected inside the overall frame 1; an electric conveying mechanism 3 for horizontally pushing the vanadium redox flow battery stack is provided at the top of the moving bracket; two lifting mechanism mounting plates 4 are fixedly connected to one outer surface of the overall frame 1; the outer surface of the moving bracket is fixedly connected to the drive assembly, which drives the lifting platform to move along the height direction of the moving bracket; casters 6 are provided at the four corners of the bottom of the overall frame 1; and the bottom of the overall frame 1 is fixed at the four corners. The system is connected to feet 5, and four casters 6 are equipped with braking devices. The electric transmission mechanism 3 includes an electric transmission motor 12. The output shaft of the electric transmission motor 12 is fixedly fitted with a motor drive synchronous pulley 16. The electric transmission motor 12 is fixedly installed on one side of the outer surface of the lifting platform by screws. Multiple load-bearing wheels 14 are rotatably connected to the inner wall of the lifting platform. Roller driven synchronous pulleys 15 are rotatably connected to both sides of the outer surface of the lifting platform near one edge. A rubber roller 13 is movably embedded in the inner wall of the lifting platform near the center. Three motor driven synchronous pulleys 17 are fixedly connected to the outer surface of the rubber roller 13. The outer surface of one motor driven synchronous pulley 17 is coupled to the outer surface of the motor drive synchronous pulley 16, and the outer surfaces of the other two motor driven synchronous pulleys 17 are coupled to the outer surfaces of the two roller driven synchronous pulleys 15, respectively.

[0023] In this embodiment, during the use of a field installation and replacement device for a vanadium redox flow battery stack, the braking devices of the four casters 6 are released, and the overall frame 1 is pushed. Utilizing the multi-angle steering characteristics of the casters 6, the device's direction of travel is flexibly adjusted until it is aligned with the external battery stack. At this point, the braking devices of all casters 6 are locked to prevent the wheels from rolling. The feet 5 are lowered, ensuring close contact between the bottom of the feet 5 and the ground. The feet 5 support the weight of the distribution device and the battery stack, preventing displacement and tilting during operation and providing a stable foundation for subsequent lifting and conveying actions. When it is necessary to move the battery stack... When the stack is precisely raised to the height matching the installation position and the starting point of the transport, the lifting motor 7 is started. The output shaft of the lifting motor 7 drives the lifting screw 8 to rotate, thereby moving the lifting platform synchronously until the stack is raised to the designated height. When it is necessary to push the stack horizontally to the installation position and move it from the installation position to the lifting platform to complete the final operation of transport and replacement, the electric transmission motor 12 is started. The output shaft of the electric transmission motor 12 drives the motor drive synchronous pulley 16 to rotate. The motor drive synchronous pulley 16 drives the motor driven synchronous pulley 17 to rotate through the synchronous belt, thereby driving the roller driven synchronous pulley 15 and... When the rubber roller 13 rotates, its surface has anti-slip properties, which increases the friction with the bottom of the battery stack and prevents slippage during pushing. The battery stack is placed on the support surface formed by the rubber roller 13 and the load-bearing wheel 14. The rotation of the wheel generates a horizontal driving force, pushing the battery stack along the rolling direction of the wheel until the external vanadium redox flow battery stack is moved horizontally to the appropriate position. After the battery stack is transported and replaced, the lifting motor 7 and the electric transmission motor 12 are turned off, the foot 5 is released, the universal wheel 6 brake is released, and the device is moved to an idle area to await the next operation. This device uses an overall frame 1 combined with universal wheels to achieve this. The casters 6 and feet 5 enable handling and replacement in various complex indoor and outdoor environments, ensuring the flexibility of the equipment. Meanwhile, the lifting motor 7 and electric transmission motor 12 are electrically driven throughout the lifting and transmission process, reducing manual handling and lowering the labor intensity of handling hundreds of kilograms of fuel cell stacks. This solves the problem that existing vanadium redox flow battery stacks mainly rely on manual labor in conjunction with ordinary lifting equipment, which makes it difficult to enter and carry out operations in some narrow construction areas, resulting in low efficiency in handling and replacing fuel cell stacks. At the same time, manual handling and replacement are labor-intensive and pose certain safety hazards.

[0024] like Figure 1-6 As shown, the drive assembly includes a lifting motor 7, a lifting screw 8, and a screw nut 9. The lifting motor 7 is fixedly installed at the bottom of the overall frame 1 by screws. One end of the lifting screw 8 is fixedly connected to the output shaft of the lifting motor 7, and the other end of the lifting screw 8 is rotatably connected to the top of the overall frame 1. The inner wall of the screw nut 9 is threadedly connected to the outer surface of the lifting screw 8, and the outer surface of the screw nut 9 is fixedly connected to the outer surface of the lifting platform.

[0025] In this embodiment, when the fuel cell stack is precisely raised and lowered to a height matching the installation position and the starting point of transportation, the lifting motor 7 is activated. The output shaft of the lifting motor 7 drives the lifting screw 8 to rotate around its own axis to correspond to the raising and lowering of the lifting platform. The lifting screw 8 and the screw nut 9 are threadedly engaged. When the lifting screw 8 is raised and lowered, the screw nut 9 moves linearly along the axis of the lifting screw 8. Since the screw nut 9 is fixedly connected to the lifting platform, it drives the lifting platform to move synchronously. By controlling the speed of the lifting motor 7, the stopping height of the lifting platform can be precisely adjusted so that the bottom of the fuel cell stack is horizontally aligned with the installation base and the target transportation position, meeting the height adaptation requirements in different scenarios. This device drives the lifting screw 8 to rotate through the lifting motor 7, and the lifting screw 8 drives the screw nut 9 to move along its axis, thereby driving the lifting platform to rise and fall. This lifting screw 8 transmission method has the advantages of high transmission accuracy and stable operation, and can accurately control the lifting height of the fuel cell stack, ensuring the accuracy of the on-site installation and replacement device for vanadium redox flow battery stacks.

[0026] like Figure 1-6 As shown, the inner wall of the lifting mechanism 2 is fixedly connected to a linear guide rail 10 extending along its height direction, and the outer surface of the lifting platform is fixedly connected to a guide rail slider 11. The outer surface of the guide rail slider 11 is slidably connected to the inner wall of the linear guide rail 10.

[0027] In this embodiment, when the electric stack is precisely raised and lowered to a height matching the installation position and the starting point of transportation by starting the lifting motor 7, the output shaft of the lifting motor 7 drives the lifting screw 8 to rotate, thereby raising and lowering the lifting platform. The guide rail slider 11 on the outer wall of the lifting platform is embedded in the linear guide rail 10. The linear guide rail 10 extends along the height direction of the lifting mechanism 2. The guide rail slider 11 slides along the linear guide rail 10 with the lifting platform, limiting the horizontal deviation of the lifting platform and ensuring that the electric stack lifting process is smooth and without shaking. This device, through the cooperation of the linear guide rail 10 and the guide rail slider 11, can guide the lifting movement of the lifting platform, prevent the lifting platform from deviating during the lifting process, and improve the stability of the lifting mechanism 2.

[0028] The usage and working principle of this device: During use, the braking devices of the four casters 6 are released, and the overall frame 1 is pushed. Utilizing the multi-angle steering characteristics of the casters 6, the device's direction of travel is flexibly adjusted until it is aligned with the external battery stack. At this point, the braking devices of all casters 6 are locked to prevent the wheels from rolling, and the feet 5 are lowered to ensure close contact with the ground. When it is necessary to precisely lift the battery stack to a height matching the installation position and transport starting point, the lifting motor 7 is activated. The output shaft of the lifting motor 7 drives... The lifting screw 8 rotates around its own axis to correspond to the raising and lowering of the lifting platform. The lifting screw 8 and the screw nut 9 are threadedly engaged. When the lifting screw 8 is raised, the screw nut 9 moves linearly along the axis of the lifting screw 8. Since the screw nut 9 is fixedly connected to the lifting platform, it drives the lifting platform to move synchronously. The guide rail slider 11 on the outer wall of the lifting platform is embedded in the linear guide rail 10. The linear guide rail 10 extends along the height direction of the lifting mechanism 2. The guide rail slider 11 slides along the linear guide rail 10 with the lifting platform, limiting the horizontal offset of the lifting platform until the fuel cell stack raised to the specified height is horizontally pushed to the installation position and from the... When the installation position is moved to the lifting platform and the final operation of transportation and replacement is completed, the electric transmission motor 12 is started. The output shaft of the electric transmission motor 12 drives the motor drive synchronous pulley 16 to rotate. The motor drive synchronous pulley 16 drives the motor driven synchronous pulley 17 to rotate through the synchronous belt, which in turn drives the roller driven synchronous pulley 15 and the rubber roller 13 to rotate. The surface of the rubber roller 13 has anti-slip properties. The battery stack is placed on the support surface formed by the rubber roller 13 and the load-bearing wheel 14. The rotation of the wheel generates a horizontal driving force, which pushes the battery stack to move along the rolling direction of the wheel until the external vanadium redox flow battery is charged. After the stack is moved horizontally to a suitable position and the stack is moved and replaced, the lifting motor 7 and the electric transmission motor 12 are turned off, the foot 5 is released, the brakes on the casters 6 are released, and the device is moved to an idle area to await the next operation. This invention is particularly suitable for the construction site of containerized vanadium redox flow battery energy storage systems. For stacks weighing 100kg-500kg each, it can realize the handling and replacement in various complex indoor and outdoor environments. In scenarios such as narrow passages in factory buildings, outdoor mountain energy storage stations, and containerized energy storage systems, it fills the technical gap of dedicated on-site handling equipment for vanadium redox flow battery stacks.

[0029] The wiring diagrams of the lifting motor 7 and the electric transmission motor 12 in this invention are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the lifting motor 7 and the electric transmission motor 12 will not be explained in detail.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
