A Hydraulically Driven Fully Vectored Waterjet Propeller Nozzle

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 nozzle of a full vector water jet, in particular to a nozzle of a hydraulically driven full vector water jet, belonging to the technical field of the shipbuilding industry. Background technique [0002] There are many ways to control the propulsion of waterjets, but there are two main types of technologies that are relatively mature and widely used. One is the use of devices that change the output power of waterjets, and the other is to adjust waterjets. A device that sprays water from a generator. The device for changing the output power of water-jet propulsion usually adopts the method of installing multi-stage gearboxes. Its structure is complex, requires a large space, high one-time investment, and high later use and maintenance costs. Therefore, this method can only be applied to large-scale For the initial design and manufacture of equipment (such as ships, etc.), existing equipment cannot be modified. [0003] Compared with...

AI Technical Summary

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 propulsion force. Therefore, it can only provide propulsion force in a few fixed directions; The direction of the water flow can only be sprayed in a fixed direction, and its adjustment ability is limited; (4) The current device for adjusting the water flow of the water jet propeller cannot make full use of the power of the water jet propeller according to the operating status of the equipment, resulting in energy loss and lack of motivation
