Embodiment Construction

[0048] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] The self-flowing cooling system of the ship is installed on the ship, and generally includes a water diversion port 10 and a cooling pipeline. The water diversion port 10 uses the dynamic pressure conversion function and the cooling water pump to introduce seawater into the cooling pipeline, and the cooling pipeline can pass seawater to each heat source. The equipment cools down a...

Abstract

The invention relates to the technical field of ship vibration control, and provides a vibration control method and device for a water diversion port structure of a ship self-flow cooling system, the self-flow cooling system and a storage medium. The vibration control method for the water diversion port structure of the ship self-flowing cooling system comprises the steps that the disturbance intensity of the inner wall of a water diversion port is repeatedly adjusted, and the total vibration intensity of the tail end of the water diversion port is correspondingly obtained; obtaining the disturbance intensity corresponding to the minimum total vibration intensity, and taking the disturbance intensity as operation disturbance intensity; and controlling the inner wall of the water diversion port to generate disturbance according to the operation disturbance intensity. According to the vibration control method for the water diversion port structure of the self-flow cooling system of the ship, vortex-induced vibration can be effectively restrained, structural fatigue can be effectively relieved, and the safety and reliability of ship operation are improved.

Description

technical field [0001] The invention relates to the technical field of ship vibration control, in particular to a method, device, artesian cooling system and storage medium for controlling structural vibration of a water intake of a ship artesian cooling system. Background technique [0002] In order to reduce the pump power loss of the cooling system through the sea and improve the energy utilization efficiency, large ships are generally equipped with an artesian cooling system, that is, a water diversion port is set, and seawater is introduced by means of dynamic pressure conversion, and the cooling pipeline provides seawater for each heat source equipment. A low-power cooling water pump is installed in the cooling pipeline to supplement the automatic water supply capacity of the water inlet. [0003] Usually, due to the turbulent flow of seawater introduced by the water intake of the artesian cooling system and the poor stability of the flow field, it is easy to induce vo...
