Problems solved by technology

However, the existing devices for adjusting the water jet jet have the following four obvious defects: (1) the adjustment method using the steering rudder has a large energy and power loss, which is not conducive to high-speed adjustment; (2) the adjustment method using the steering valve The adjustment method is to input the water flow into the nozzles in different directions to achieve the purpose of controlling the direction of the ...

Abstract

The invention discloses a hydraulically-driven full-vector water-jet propulsor spout and belongs to the technical field of ship industry. The propulsor spout comprises a rotary blade component, swing blades, a sealing base, a rotary support sleeve, a clamping cap, a hydraulic motor and a hydraulic cylinder. Peripheral equipment is a controllable hydraulic pump system, which comprises a hydraulic pump, a control system, a hydraulic valve and a hydraulic circuit and is used for providing required power for the hydraulic motor and the hydraulic cylinder respectively according to the working conditions; the swing blades are mounted on the rotary blade component and are driven to swing by the hydraulic cylinder; and the rotary support sleeve is matched with the sealing base and the clamping cap and can rotate along the axis, and the rotary blade component is mounted on the rotary support sleeve and is driven to rotate through the hydraulic motor. The propulsor spout provided by the invention can achieve full-vector adjustment of the flow rate of a propulsor as required so as to control the propelling effort and direction of the water-jet propulsor.

Description

technical field [0001] The invention relates to a full-vector water-jet nozzle, in particular to a hydraulic-driven full-vector water-jet nozzle, which belongs to the technical field of the shipbuilding industry. Background technique [0002] There are many ways to control the propulsion of waterjet propulsion, but there are mainly two types of technologies that are relatively mature and widely used at present, one is to use devices that change the output power of waterjet propulsion, and the other is to adjust the propulsion of waterjet. A device that sprays water from the device. The device for changing the output power of water jet propulsion usually adopts the method of installing a multi-stage gearbox. Its structure is complex, it needs to occupy a large space, the one-time investment is high, and the later use and maintenance costs are high. Therefore, this method can only be applied to large-scale For the initial design and manufacture of equipment (such as ships, et...
