Problems solved by technology

[0008] Modern ships are developing in the direction of large-scale, high-speed and multi-working conditions. Although the above-mentioned propulsion methods have their own advantages, they all show certain limitations when facing the development direction of modern ships, which restricts the development of ships. Therefore, The development of ship propulsion devices with better comprehensive performance has become an important topic in the field of ship propulsion

Embodiment Construction

[0033] According to the power of the ship and the actual needs, select or design the appropriate parts 1~59, and follow the attached figure 2 , 3 Assembled as shown, reasonably arranged in a suitable position in the ship's engine room (not shown in the figure). When the system is running, host 1, first clutch 3, second clutch 5, third clutch 6, fourth clutch 7, servo valve 13, start valve 18, three-position four-way solenoid valve 28, two-position three-way solenoid valve 40 And all the electromagnetic reversing valves (48-59) in the eleventh combined element are controlled by a computer (not shown in the figure) in a unified manner.

[0034] When receiving the starting command, open the third clutch 6, the main engine 1 is in a light-load state; the starting valve 18 is energized, and the suction and discharge ports of the two-way variable pump 15 are connected. When the main engine 1 reaches the set speed, close the third clutch 6, The hydraulic system is driven to work. A...

Abstract

Disclosed are a propelling method and a device for vessels and other navigating machinery in water. The method based on the hydraulic transmission principle includes transforming mechanical energy output by a plurality of main engines (more than two) into pressure energy of hydraulic oil, after power integration and distribution, respectively driving a propeller screw, a steering engine (which can be canceled after employing a pod revolving device), a lateral-thrust unit and other auxiliary devices, using a shaft generator to replace a ship auxiliary engine, adjusting revolution rate and steering of the propeller screw by controlling a pump and the main engines, realizing coordinated working of other auxiliary devices of the propeller screw, the steering engine, the lateral-thrust unit and the like and various working modes of the main propelling system, simultaneously recycling inertia energy produced by the propeller screw and vessel in the brake process and the like. The propelling method has the advantages of flexible engine room arrangement, large power-to-weight ratio of devices, high safety and reliability, high maneuverability, good work condition engaging characteristic, strong overload protection capacity, inertia energy recycle and the like.

Description

technical field [0001] The invention relates to a comprehensive hydraulic propulsion method and device for a ship, that is, based on the principle of hydraulic transmission, the mechanical energy output by multiple (two or more) main engines is converted into hydraulic energy, and after power integration and distribution, the propellers and steering gears are respectively driven , side thruster and other auxiliary devices, shaft generators should be used instead of auxiliary machines. It is mainly used on all kinds of ships, warships, submarines and other underwater navigation objects. Background technique [0002] In modern ships, due to the different requirements of the main engine type, ship use and propulsion performance, the propulsion device adopts many transmission modes. In the marine diesel engine power plant, the transmission mode is generally divided into three categories: direct transmission, indirect transmission and special transmission. Among them, special tr...
