Intelligent marine diesel engine attitude adjusting device

Abstract

The invention relates to the technical field of marine diesel engines, discloses an intelligent marine diesel engine attitude adjusting device, and aims to solve the problems that when a propulsion shafting of a ship runs, vibration is inevitably generated due to the influence of dynamic factors such as propeller hydrodynamic force, hull deformation and a lubricating film, and meanwhile, the operation of a diesel engine connected with the propulsion shafting also generates vibration; according to specifications, the marine diesel engine and the propulsion shafting must be subjected to vibration checking calculation, so that vibration sources are controlled, vibration is reduced, vibration sources are isolated, and equipment and personnel are protected; the intelligent marine diesel engine attitude adjusting device comprises a diesel engine upper-layer base, a diesel engine lower-layer base, a lateral clamping mechanism, swing jacking mechanisms, a ship body attitude sensor and a controller, and the controller controls the multiple swing jacking mechanisms to independently operate according to ship body attitude information obtained by the ship body attitude sensor. Posture adjustment of the lower-layer base of the diesel engine is achieved so as to reduce/eliminate swing amplitude of the marine diesel engine caused by stormy waves.

Description

technical field [0001] The invention relates to the technical field of marine diesel engines, in particular to an intelligent attitude adjustment device for marine diesel engines. Background technique [0002] The marine diesel engine is the main power device on the ship. The working process of the diesel engine has many similarities with the gasoline engine. Each working cycle also undergoes four strokes of intake, compression, work, and exhaust. When working, the combustion gas is placed in the Combustion is carried out in the cylinder, and then the change of the air pressure in the cylinder drives the reciprocating motion of the piston, thereby driving the movement of the propeller in the ship, and then achieves the purpose of driving the ship. During the working process of the marine diesel engine, the combustion of the gas in the cylinder and the driving of the piston will cause the marine diesel engine to vibrate strongly with each other. Existing damping devices are ...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned devices are all equipped with elastic shock absorbers on the base of the marine diesel engine. Firstly, the impact of the swing of the hull itself due to the impact of waves on the vibration of the diesel engine is not considered. Secondly, because the bottom of the marine diesel engine is connected to the base through the shock absorber, The elasticity of the shock absorber will reduce the lateral support of the diesel engine, so after the hull swings in multiple directions in wind and waves, it will aggravate the shaking of the diesel engine body
