Design method and device for telescopic tank group

 Disclosed are a design method and device for a telescopic tank group. With this structure, a tank truck can be loaded with goods on the way to and back from the destination, hence solving the problem that the tank truck is empty in half of the trip. Besides, the tank truck can transport two or more goods each time. The tank group is telescopic, and each tank can be loaded with one kind of liquid (gas, powder, or other chemical products) separately, and therefore the entire tank group is capable of containing two or more products. Each tank is small in size and can bear greater working pressure. When some tank is in danger of leakage, the danger does not affect the entire tank group immediately, thereby improving the safety of the entire tank group. During the stretching of the tank group, stable balance settings are provided to ensure that the tank group reaches a designated position. After the tank group reaches the designated position, stabilizing bolts and fixing flanges are provided to keep the tank group stable and sealed.
