The invention discloses a sea ice collecting device system which comprises a sea ice breaking device and a sea ice fishing and transporting device. The sea ice breaking device comprises a double-floating-body ice breaking platform, a first connecting bridge, a wooden protective bottom, a lifting pile leg, a hydraulic motor, a first generator set, a hydraulic excavator, an ice crushing bucket, a first thruster and a first navigation bridge. The sea ice fishing and transporting device comprises a double-floating-body ice fishing platform, a second connecting bridge, a double-roller type ice crushing machine, a chain plate type ice collecting machine, a transverse ice transporting machine, a second generator set, a second thruster and a second navigation bridge. The invention further discloses a using method of the sea ice collecting device system. The problems including ice breaking, ice crushing, ice fishing, ice transportation and the like are solved in one time. The requirements for implementation of scale-type sea ice collecting projects in main sea ice gathering regions-coastwise and coastal regions are met, the cost is reduced, the stability and the effectiveness of the system in operation are improved, mobile operation in narrow water areas is facilitated, response to changeful sea conditions on the sea is facilitated, and maintenance is facilitated.
