An intelligent marine diesel engine attitude adjustment device

Abstract

The invention relates to the technical field of marine diesel engines, and discloses an intelligent marine diesel engine attitude adjustment device. When the propulsion shafting of a ship is in operation, vibrations are inevitably generated under the influence of dynamic factors such as propeller hydrodynamic force, hull deformation, and lubricating film. At the same time, the operation of the diesel engine connected to the propulsion shafting will also generate vibration. According to the regulations, the marine diesel engine and the propulsion shafting must be checked and calculated to control the vibration source and reduce vibration, isolate the vibration source and protect equipment and personnel. The attitude adjustment device of the intelligent marine diesel engine of the present invention comprises an upper base of the diesel engine, a lower base of the diesel engine, a lateral clamping mechanism, a swing jacking mechanism, a hull attitude sensor and a controller. The two swing jacking mechanisms operate independently to adjust the attitude of the lower base of the diesel engine to reduce / eliminate the swing amplitude of the marine diesel engine due to wind and 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
