Description

Damping capable of resisting up-and-down fluctuation of ship body

Technical Field

The invention relates to damping for resisting up-and-down fluctuation of a ship body, and belongs to the technical field of ship accessories.

Background

With the continuous improvement of the living standard of people and the rapid development of social economy, the number of pleasure boats in water transportation and parks, lakes, sinks and the like is increasing. In recent years, large pleasure-boats and pleasure-boats at home and abroad are raised, the tourism type boats are often parked at ports or on the shore for a long time, personnel on the boats frequently move during parking, and the influence on the boats is inevitable under a storm environment, so that the passengers are dizzy, and the problems of cargo displacement, hull structure damage and the like are caused due to jolt. Therefore, a patent and a product with simple structure, low production cost and good anti-jolting performance are urgently expected by people in the field.

An anti-bump device for ship, such as 201610269296.6, is composed of a hull, a heavy plumb body at the bottom of hull and connected to hull via connecting rod or hinged to hull via draught regulating mechanism. The device is suitable for various ships, and when the ship body sinks, floats and jolts on two sides, the heavy pendants can play a role in damping the jolt amplitude, so that the ship body gradually tends to be stable, and the side turning of the ship body can be prevented; however, the heavy pituitary is rigidly connected with the hull, and the heavy pituitary and the hull synchronously fluctuate and bump under the condition of insufficient draft of the hull, so that the heavy pituitary is worthless.

For example, the anti-bump device of a ship with the publication number of 202783726U is characterized in that a motor is fixedly arranged at the bottom of a ship body, a wheel sheet is arranged on a motor shaft, and a speed regulating handle is arranged on a control console of a cab in the ship body so as to regulate the rotating speed of the wheel sheet according to the wind and wave on water. The technology damps the jolt of the ship body by stirring the water body under the ship, is not ideal enough to consume more power, and brings adverse effect on the control of the driving direction of the ship; secondly, the structure has little damping effect on the impact of water waves to the upper part of the ship body, so the effect of overcoming the jolt of the ship body is not ideal.
