The invention provides a piston type low-noise underwater robot vector water-jet propeller which comprises a water-jet propeller body, and the water-jet propeller body comprises a propeller shell, a plurality of electrically-controlled reversible one-way valves, an electrically-controlled piston, a piston electric push rod, a motor, a front end cover, a rear end cover, a motor mounting frame and a propeller body mounting frame. The electric control piston, the front end cover and the rear end cover are each provided with four electric control reversing one-way valves which are arranged in the axial horizontal direction, the electric control reversing one-way valves are controlled through the controller, the water flow spraying direction can be switched, and therefore switching of the thrust output direction of the thruster is achieved. Compared with a propeller thruster, the piston type water-jet thruster provided by the invention has lower underwater noise, so that the submersible has lower navigation noise, hidden navigation of the submersible is facilitated, and the submersible is not easily found by sonar. Compared with a propeller thruster, the piston type water-jet thruster provided by the invention is not easily wound by fishing net ropes and the like in the underwater navigation process due to the fact that the piston type water-jet thruster is not provided with rotating structures such as propellers and the like, so that the piston type water-jet thruster has higher reliability and adaptability compared with the propeller thruster.
本发明提供了一种活塞式低噪声水下机器人矢量喷水推进器,包括喷水推进器本体,所述喷水推进器本体包括推进器外壳、多个电控可换向单向阀、电控活塞、活塞电推杆、电机、前端盖、后端盖、电机安装架和推进器本体安装架。本发明通过在电控活塞、前端盖和后端盖上各安装有4个电控可换向单向阀,均沿轴向水平方向设置,电控可换向单向阀通过控制器控制,能够实现切换水流喷出的方向,从而实现推进器推力输出方向的切换。本发明提供的活塞式喷水推进器相较于螺旋桨推进器有更低的水下噪声,能使潜水器有更小的航行噪声,更有利于潜水器隐蔽航行,不容易被声呐发现。本发明提供的活塞式喷水推进器相较于螺旋桨推进器因没有螺旋桨等转动结构,在水下航行过程中不容易被渔网绳索等缠绕,因此,相较于螺旋桨推进器有着更高的可靠性和适应性。
