The invention discloses a high-thrust water jet propulsion device capable of flexibly turning and changing speed. The high-thrust water jet propulsion device comprises a bent pipe type inlet with an anti-blocking function, a multi-level acceleration impeller, a twisted impeller, a secondary impeller, a balance drum, a double-flow-line guide vane, a turning device and a speed changing nozzle structure. The anti-blocking device at the bent pipe type inlet can directly block large sundries and collect small sundries which are easy to block into the sundries collecting chamber; the multi-level acceleration impeller, the twisted impeller and the secondary impeller progressively increase the fluid speed layer by layer, and then the axial force is balanced through the balancing drum. The double-flow-line guide vane gathers the fluid and uniformly guides the fluid to the variable-speed nozzle, and part of kinetic energy of the fluid is converted into pressure energy; the turning device and the variable-speed nozzle can change the moving direction and speed of the water spraying propelling device. The propeller is high in propelling efficiency, good in noise performance and high in concealment performance, can be used as a power source of an underwater navigation body, and can also be widely applied to propelling systems of water equipment.
