Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0031] Small ships refer to ships with a small draft. When a small ship is berthing, due to its small draft, it is easy to sway under the influence of external forces and its own propulsion device. As a result, it will have a greater impact on the comfort of the crew's work and life. In the related art, although rubber tires are arranged on the wharf to damp the vibration of the ship, the effect is limited.

[0032] In order to solve this problem, an embodiment of the present disclosure provides a vibration damping system for a small ship, such as figure 1 As shown, the small ship vibration damping system includes a power unit 1 , a three-position four-way reversing valve 2 , an energy storage unit 3 , a compensation unit 4 and a...

Abstract

The disclosure provides a small ship vibration damping system, which belongs to the technical field of hydraulic pressure. The small ship vibration damping system includes a power unit, a three-position four-way reversing valve, an energy storage unit, a compensation unit and a damping oil cylinder; the power unit includes a pump set, and the oil inlet of the pump set is connected to the oil tank of the small ship damping system; The middle function of the three-position four-way reversing valve is O-type, the oil inlet of the three-position four-way reversing valve is connected with the oil outlet of the pump unit, and the oil return port of the three-position four-way reversing valve is connected with the fuel tank. The first working oil port of the three-position four-way reversing valve communicates with the rodless chamber of the damping cylinder, and the second working oil port of the three-position four-way reversing valve communicates with the rod chamber of the damping cylinder; the energy storage unit includes The accumulator; the compensation unit includes a first sequence valve, a two-position two-way reversing valve, a three-position three-way reversing valve, a second sequence valve and a third sequence valve. The present disclosure can reduce the shaking and swinging of small ships when berthing.

Description

technical field [0001] The disclosure belongs to the field of hydraulic technology, in particular to a vibration damping system for small ships. Background technique [0002] When a small ship is berthing, due to its small draft, it is easy to sway under the influence of external forces and its own propulsion device. As a result, it will have a greater impact on the comfort of the crew's work and life. [0003] In related technologies, in order to solve this problem, rubber tires are usually arranged on the wharf, and the small ships are offset against the rubber tires, thereby playing a certain role of vibration reduction. [0004] However, the vibration damping ability of the rubber tire is limited, so the shaking of small ships is still serious. Contents of the invention [0005] An embodiment of the present disclosure provides a vibration reduction system for a small ship, which can reduce the shaking of the small ship when berthing. Described technical scheme is as...
