The invention discloses a container ship cargo compartment ventilation structure. The container ship cargo compartment ventilation structure is arranged in a cargo compartment, a compartment cover isarranged at the top of the cargo compartment and provided with an air inlet and air outlets, and the container ship cargo compartment ventilation structure is characterized in that the air inlet is formed in the middle of the compartment cover, and the air outlets are formed in the left side and the right side of the air inlet correspondingly; the air inlet is connected with a frequency conversionair-supplying fan, and the frequency conversion air-supplying fan is connected with an air supplying pipe; an air inlet pipe is located on the lower part of the air inlet, and the air supplying pipevertically extends from the top of the cargo compartment to the bottom of the cargo compartment; the air supplying pipe is provided with a plurality of air supplying openings; the air outlets are connected with a frequency conversion air-pumping fan, and the frequency conversion air-pumping fan is connected with air pumping pipes; the air pumping pipes are located on the lower parts of the air outlets; a plurality of air pumping openings are formed in the air pumping pipes; the air supplying pipe is located in the middle of the cargo compartment; and the air pumping pipes are located on the two sides of the air supplying pipe. The container ship cargo compartment ventilation structure has the advantages of good ventilation effect, low energy consumption and easy mounting and maintenance.
