At present, in order to fully utilize the effective volume in the container frame and truly improve the application economic benefit of the tank container, the tank body of the tank container adopts a large-volume tank body technology. In order to ensure that the volume is enlarged and the tank body has good mechanical properties, the section of the tank body is in an octahedral arc shape. This type of tank is currently commonly used for liquid cargo transportation. Although the tank body of the type utilizes the circular arc as much as possible to improve the pressure bearing capacity of the tank body, the pressure bearing capacity of the whole tank body is still reduced more than that of a cylindrical tank body, and the tank body is weaker in self rigidity and easier to deform. In order to improve the pressure bearing capacity and rigidity of the tank body, a reinforcing ring is required to be arranged in or outside the tank body according to the related standard requirements of the existing pressure container in China. The tank reinforcing rings are generally matched with the tank body inside and/or outside to be uniformly distributed in a certain size, more importantly, the reinforcing rings are arranged in the tank body, if a certain fluidized bed setting gap is reserved at the bottom of the tank body, corresponding sections of the existing reinforcing rings are required to be disconnected, but according to the relevant standard requirements of the reinforcing rings, the disconnected length cannot exceed the specified requirements or reinforcing structures are required to be arranged at the corresponding positions outside the tank body, and thus, great challenges are brought to the design of the reinforcing rings in the tank body of the tank container for paving the fluidized bed to perform wind pressure unloading. Although the reinforcing ring structure can be arranged outside the tank body, the space of the external frame of the current large-volume tank container is extremely limited, and the reinforcing ring structure which accords with the section of the preset inertia distance is difficult to be arranged at all. Now, for large volume tank container structures, external reinforcement structures are typically used as a complement to in-tank reinforcement structures. The above situation also causes the most obstacle that the large-volume tank body is mostly applied to liquid cargo transportation but cannot be applied to powder cargo transportation and unloading.
