专利一:迷宫切割式轴系防缠绕推进装置 专利号:96230784

Patent N0.1 Anti-twist labyrinth contra-rotating propeller
·针对我国江河沿海多泥沙、缠绕物开发的本专利.结合对转桨生产的对转桨(轴系)防缠绕舵桨。
集常规Z型推进装置的机动性好与对转桨的高效率于一身。
·lt is specially designed for China coastal areas which are fuIl of sediment and entanglement.and combined with kaplan(shafting)anti-twist rudder blade.it unites the good motility of propulsion unit and high efficiency of kaplan.
·轴系防缠绕切割装置可排除水草、尼龙绳等对轴系的缠绕,有利保护轴系密封。
·Anti-twist shaft cuffing device can get rid of water plants and nylon wound on the shafting,protecting the shaft seal favorably.

专利二:全回转对转桨前后置导管推进装置 专利号:97206542.3

Patent NO.2 Contra-rotating propeller with nozzle
·本专利在于创造一种新型的对转桨前后置导管推进结构形式.以提高它在各种负荷下的推进效率.达到节能效果和拓宽其应用范围。
·This paten is to a new contra-rotating Kaplan structure to improve its propulsion emciency under various load,saving enemy and widening its other application.

专利三:吊舱型对转桨牵引式水翼组合推进装置 专利号:03209631.3

Patent NO.3 Draught hydrofoil podded propulsion with contra-rotating propeller
·本专利将水翼船三种独立作用的装置集成在一起.吊舱型推进可在任意侵沉下提供推力.水翼省略了原有单独的支柱.减轻了重量,
舵装置省略了单独的舵承系统.装在吊舱的支柱形成了襟翼舵,简单了结构,提高了舵效。
·This patent will integrate three types of independent role of the hydrofoil device.The tandem type podded propulsion device can supply power immersed under any water,hence,the hydrofoil saves the original separate pillars,reducing weight.The rudder unit saves separate rudder bearing system,therefore,pillars in the hydrofoil forms the flap-type rudden simplifying the structure and improving the steerage
