The pressurizing ducted propeller with the intelligent double rudder blades is reasonable in design, large in propelling force, not prone to being influenced by external factors during reversing and good in reversing effect. The propeller comprises a propeller shell provided with a cavity, the propeller shell is provided with a water inlet and a water outlet which are communicated with the cavity, a pressurizing duct is arranged in the propeller shell, an inlet of the pressurizing duct is communicated with the water inlet, an outlet of the pressurizing duct is communicated with the water outlet, and a main engine and a propeller are arranged in the pressurizing duct. A reverse flow water channel is formed in a gap between the lower end of the pressurizing duct and the lower cavity wall of the cavity of the propeller shell, the two ends of the reverse flow water channel communicate with the water inlet and the water outlet correspondingly, two flow guide rudder blades are rotationally arranged at the water outlet, and two synchronous steering engines in transmission connection with the two flow guide rudder blades are arranged on the propeller shell. And the water outlet is blocked when the two flow guide rudder blades rotate to be connected with each other. The propeller can be applied to the technical field of propellers.

    本发明旨在提供一种设计合理、推进力度大、倒车不易受外界因素影响且倒车效果较好的带智能双舵叶的增压涵道推进器。本发明包括设有空腔的推进器壳体,推进器壳体上设有与该空腔相连通的进水口和出水口,推进器壳体内设置有增压涵道,增压涵道的入口与进水口连通,增压涵道的出口与出水口连通,增压涵道内设置有主机及螺旋桨,增压涵道的下端与推进器壳体的空腔下腔壁之间的间隙形成一反流水道,反流水道的两端分别与进水口和出水口连通,出水口处转动设置有两片导流舵叶,推进器壳体上设置有两个与两片导流舵叶传动连接的同步舵机,两片导流舵叶转动至相互连接时将出水口封堵。本发明可应用于推进器的技术领域。
