Paired air pressure energy storage device, inspection method and balance detection mechanism thereof

A paired air pressure energy storage device, comprising an inner body and an outer body sleeved outside the inner body;

• wherein the inner body is filled with a first gas;
• the outer body is not in direct contact with the inner body;
• an annular cavity is formed between the outer body and the inner body;
• the cavity is filled with a second gas;
• a gas energy pressure difference exists between the first gas and the second gas;
• and the gas energy pressure difference is a relative pressure difference;
• and the paired air pressure energy storage device is internally provided with a plurality of brake isolation support mechanisms;
• the inner body is divided into a plurality of inner compartments by the plurality of brake isolation support mechanisms;
• the cavity formed between the outer body and the inner body is divided into a plurality of outer compartments by the plurality of brake isolation support mechanisms;
• the brake isolation support mechanisms are provided with a plurality of first diversion channels and a plurality of second diversion channels;
• the plurality of outer compartments are communicated with each other through the plurality of second diversion channels;
• and the plurality of inner compartments are communicated with each other through the plurality of first diversion channels.
