The utility model discloses a multi-tank fused salt heat storage system driven by coupling compressed gas and a fused salt pump. The multi-tank fused salt heat storage system comprises a low-temperature fused salt tank, a high-temperature fused salt tank, a salt storage tank, a compressed gas device, a heat exchanger, the high-temperature fused salt pump, the low-temperature fused salt pump, a high-temperature fused salt valve, a low-temperature fused salt valve, a gas valve and a heat absorber. The number of the salt storage tanks is not less than 2, and the salt storage tanks are arranged inparallel. The salt storage tank has the beneficial effects that a plurality of salt storage tanks are arranged in parallel, so that the volume of a single salt storage tank is reduced, and the processing and manufacturing difficulty and the investment cost of the salt storage tanks are reduced; the utilization rate of the fused salt tank is increased, normal operation of the system is not affected when any single salt st
