[0045] When water is supplied to the accommodating cavity through the water tank assembly to extinguish a fire, water is accumulated in the accommodating cavity. After the fire is extinguished, the water can be discharged or collected through a drainage pipe, further improving the use effect of the present invention.

[0046] A battery transport plate 12 for convenient battery transportation is placed on the upper end of the pallet 10, and a plurality of bull's eye rollers 1201 are fixedly connected to the bottom end surface of the battery transport plate 12. The bull's eye rollers 1201 are evenly spaced. The battery transport plate 12 is placed on the pallet 10 via the bull's eye rollers 1201 and can be moved on the pallet 10 under the action of the bull's eye rollers 1201.

[0047] The bottom end of the frame 1 is provided with a plurality of support assemblies 9 and is placed on the ground through the plurality of support assemblies 9, and the plurality of support assemblies 9 are arranged at equal intervals on both sides of the bottom end of the frame 1; the support assembly 9 includes a mounting plate 901, a walking wheel 902, and a positioning foot 903; the mounting plate 901 is fixedly connected to the bottom end of the frame 1, and the bottom end of the mounting plate 901 is connected to the walking wheel 902; the positioning foot 903 is arranged on one side of the walking wheel 902, and the top end of the positioning foot 903 is detachably connected to the bottom end of the mounting plate 901.

[0048] The outer periphery of the bottom end of the frame 1 is detachably connected with a support guard plate 103 , which is arranged on the outside of the support assembly 9 to shield and protect the support assembly 9 .

[0049] Before transporting the frame, the positioning feet are removed from the mounting plate so that the walking wheels are in contact with the ground, which facilitates the movement of the entire battery maintenance platform. When moving to the designated position, it is only necessary to use a forklift to lift the battery maintenance platform and install the positioning feet so that the positioning feet can be stably supported on the ground for normal maintenance. This ensures the stability of the battery maintenance platform while facilitating the movement and transportation of the battery maintenance platform, further improving the use effect of the present invention.

[0050] When performing battery maintenance operations, the present invention places the battery on a pallet via a battery transport plate, and then uses a pulling mechanism to adjust the height of the pallet. After adjusting to a suitable height, the maintenance personnel stand on the outside of the frame to perform battery maintenance operations. When encountering battery explosions and the like, the flame sensor installed in the accommodating cavity detects temperature abnormalities and causes the shutter mechanism to quickly close. The shutter mechanism quickly moves to the top of the accommodating cavity and covers it, preventing the fire from spreading and causing other fires. Then, water is released through a water tank assembly arranged on one side of the frame, allowing a large amount of water to flow into the accommodating cavity to extinguish the flame in the accommodating cavity. The battery maintenance platform can simultaneously achieve fire control and fire extinguishing effects when encountering a fire, thereby improving the safety protection performance of existing battery maintenance platforms, effectively avoiding the occurrence of safety accidents during battery maintenance, and further improving the use effect of the battery maintenance platform, which has great market promotion prospects.
