[0002] Compressed air energy storage is a technology that can store large-scale electrical energy, which mainly includes key components such as generators, compressors, combustion chambers, gas storage, expanders and motors. The gas storage, as an important part of the compressed air energy storage power station, is not only the key link to ensure the safe and stable operation of the system, but also an important factor affecting the economy of the power station.

[0003] The artificial cavern gas storage is identified as the preferred gas storage mode of the compressed air energy storage power station due to its flexible site selection, wide pressure range and various forms. The artificial cavern gas storage is generally cylindrical, with a diameter of up to 15 m and a length of more than 300 m.

[0004] During the operation of the gas storage, maintenance and repair work needs to be carried out on the gas storage at irregular intervals. Due to the high space of the gas storage, a construction platform needs to be erected for operation, but the internal size of the manhole passage into the gas storage is very limited, with a diameter generally not exceeding 1.5 m. Therefore, the maintenance operation construction platform needs to be modularly designed to meet the construction requirements of the entire cylindrical cross section of the gas storage. SUMMARY

[0016] The wide platform 401 is used for providing a user to stand;

[0017] The wide platform 401 is fixedly installed on the fixed disc 302 of the adjacent inflatable air bag 301 through the inclined pull rod 402.

[0018] Further, the inclined pull rod 402 and the pull rod 303 are both installed on the fixed disc 302 through the hand screw bolt 6.

[0019] Further, the platform further comprises a ladder 7, and the ladder 7 is fixedly installed on the fixed disc 302 in the vertical direction.

[0020] Another technical scheme of the present application is an operation method applied to the modular maintenance platform suitable for the large-diameter artificial chamber gas storage.

[0021] S1, sequentially install the base 2, the inflatable air bag module mechanism 3, the ladder 7 and the mounting artificial platform mechanism 4 in the tunnel 1 according to the specified height;
