Assembling method of side-push seal cover device

The invention discloses an assembling method of a side-push seal cover device. The assembling method of the side-push seal cover device comprises the steps of firstly assembling and welding a flow guide hole cylinder with a cylinder rib plate, then assembling and welding a rotating shaft base to the flow guide hole cylinder to enable the rotating shaft base, the flow guide hole cylinder and the cylinder rib plate to jointly form a cylinder assembly; machining the cylinder assembly; then assembling a rotating shaft assembly, rotating blades and a power mechanism to the cylinder assembly to form the side-push seal cover device; finally integrally assembling and welding the side-push seal cover device to a ship body section. By adopting the assembling method, since a rotating shaft, the rotating shaft assembly, the rotating blades and the power mechanism are assembled first and then the side-push seal cover device is integrally installed to the ship body section, the assembling of the components of the side-push seal cover device in the ship body section can be avoided, an installation period is shortened, the machining in the ship body section can be avoided and the machining difficulty can be reduced.
