The invention provides an ashore unloading inflation system matched with a compressed natural gas (CNG) ship, and relates to the technical field of natural gas conveying. The system comprises a quickly-assembled valve seat arranged on the ship, a gas storage device arranged ashore, a high-pressure pipeline and a valve, wherein the high-pressure pipeline and the valve are matched. A quickly-assembled valve head and a high-pressure hose are dynamically arranged between the quickly-assembled valve seat and the ashore gas storage device by means of an adaptation mechanism capable of being adjusted freely. The system is characterized in that the adaptation mechanism capable of being adjusted freely comprises a balance wheel, the lower end of the high-pressure hose is fixed to a port of the high-pressure pipeline, and the upper end of the high-pressure hose winds around the balance wheel, so that the quickly-assembled valve head is hung on the outer side of a rack of the adaptation mechanism; the balance wheel is hinged and positioned to a sliding sleeve to from a floating counterweight mechanism which has a rotation freedom degree in a vertical plane and a freedom degree of sliding up and down along a guide column and comprises a steel wire rope and a fixed pulley block, the steel wire rope is connected between the balance wheel and a counterweight assembly, and the fixed pulley block is arranged on the rack. The ashore unloading inflation system has the beneficial effects of preventing the high-pressure hose from being pulled and effectively protecting the hose.
