The invention provides a multi-air-pump collaborative inflation rescue salvage method and relates to the technical field of ship salvage. The multi-air-pump collaborative inflation rescue salvage method comprises the following steps of mounting a gyroscope at the bottom of a sunken ship and conducting air inflation on different cabins in the sunken ship through four or more air pump assemblies; analyzing the tilting posture of the sunken ship through the gyroscope and adjusting the air inflation volumes of air pumps according to the tilting posture to adjust the sunken ship to the level condition; and continuously conducting air inflation on the different cabins of the sunken ship through the air pump assemblies to keep the sunken ship in the level condition and enable the sunken ship to float upwards to the water surface. Through the multi-air-pump collaborative inflation rescue salvage method provided by the invention, the sunken ship can keep floating upwards stably, and the ship isprevented from losing balance and sinking when floating upwards.
