Description

Technical Field

[0001] This utility model belongs to the field of energy storage cabinet technology, and in particular relates to a mobile modular assembly energy storage cabinet. Background Technology

[0002] In today's energy sector, the importance of energy storage technology is becoming increasingly prominent. With the widespread application of renewable energy sources such as solar and wind power, and the ever-increasing demand for stable and reliable power supply, energy storage devices have become a key component in balancing energy supply and demand and improving the stability of the power system. Energy storage cabinets, as common energy storage carriers, play an important role in various scenarios.

[0003] Existing energy storage cabinets have revealed numerous problems in practical applications. Traditional energy storage cabinets are mostly monolithic structures, which are large and heavy, making them extremely inconvenient to move. Moreover, when the power demand of the application scenario changes, monolithic energy storage cabinets cannot flexibly adjust their energy storage capacity. If the demand increases, it is not easy to add energy storage modules simply and efficiently; if the demand decreases, it results in a waste of space and resources.

[0004] Some portable energy storage devices are not very stable during movement. Because the battery modules inside the energy storage device are heavy, when tilting and pulling, the operator's arms have to bear a large load, which is laborious and unsafe. When pushing horizontally, it is easy to cause an imbalance of forces, causing the device to shake or even tip over during movement, which poses a risk of damaging the device and causing safety accidents.

[0005] To address these issues, we offer mobile, modularly assembled energy storage cabinets. Utility Model Content

A circular hole for the transmission shaft 46 is formed on the surface of the mounting base 41.

[0033] Specifically: the support rail 12 provides stable support for the energy storage battery 2; the cooling fan 13 introduces external air through the air inlet, effectively reducing the temperature inside the cabinet and extending the service life of the energy storage battery 2; the heat dissipation holes of the cabinet door 14 and the cooling fan 13 form air convection, improving heat dissipation efficiency; the handle is easy to operate, enhancing ease of use; the slide rail 22 precisely matches the support rail 12; the handle facilitates the handling of the energy storage battery 2; the fixing frame 24 ensures the stability of the lithium battery 23 during transportation and use; and the threaded drive of the solenoid 481 and the lead screw 483... The lifting and lowering of wheel 485 is achieved through bevel gear transmission, which ensures efficient and stable power transmission. The cooperation between limit block 486 and limit groove 487 prevents mounting plate 484 from shifting during lifting and lowering, ensuring that wheel 485 is lifted and lowered vertically. The meshing of worm 49 and worm wheel 43 provides a large transmission ratio, making operation more labor-saving and having a self-locking function to ensure that wheel 485 will not move accidentally when fixed. The bearing seat provides stable support for drive shaft 46, and the round hole ensures smooth rotation of drive shaft 46 and reduces energy loss.

[0034] The working principle of this utility model is as follows: During assembly, adjacent cabinet components 1 are initially connected to the receiving block 32 via pins 31, and then fastened with connecting plate 34, screw 33, and nut. The energy storage battery 2 slides into the storage cabinet 11 via the support slide rail 12 and is fixed with bolts. When movement is required, the worm 49 is inserted into the inner cavity of the bearing seat and meshes with the worm wheel 43. Then, the worm 49 is rotated, and the transmission shaft 42 is rotated through the worm wheel 43 and worm 49. The power is transmitted to the solenoid 481 through the bevel gear set, driving the lead screw 483 to descend so that the wheel 485 contacts the ground. At the same time, the cabinet is raised off the ground and can be pushed to move. After reaching the designated position, the worm 49 is rotated in the opposite direction, the wheel 485 rises, and the cabinet is fixed to the ground. When the cooling fan 13 is started, external air enters from the air inlet, flows through the energy storage battery 2, and is discharged from the heat dissipation hole to achieve heat dissipation and cooling. Through the coordinated work of the above structure and transmission system, modular assembly, flexible movement, and efficient heat dissipation of the energy storage cabinet are realized.
