Problems solved by technology

However, the conventional cargo hold structure can only achieve the purpose of sloshing reduction in the case of standard loading and transportation, and cannot play the role of reducing sloshing impact for non-standard loading and transportation
In addition, the presence of ramps around conventional cargo tank structures reduces tank loads

Embodiment 1

[0019] Such as figure 1 and Figure 4 Shown: a sloshing impact reduction device for liquid cargo transportation, including thermal insulation material 2, slide rail 3, connecting rope 5, sloshing reduction component 6, slider 10 and rail 11, the warehouse wall is provided with thermal insulation material 2, The slide rails 3 are arranged at the four corners of the cargo compartment wall 1 , and the slide blocks 10 arranged in the slide rails 3 are connected to the main frame of the sloshing reduction assembly 6 through connecting ropes 5 . The slide rails 3 are fixed at the four corners of the cargo hold, so that the floating device on the anti-sloshing assembly 6 will not be too close to the bulkhead.

[0020] The anti-sloshing assembly 6 includes a frame unit 9 and baffles 8 , and the baffles 8 are arranged alternately in the frame unit 9 . The fluid flows in the channel defined by the baffles 8 . The specific setting method of the baffle plate 8 is: directly inserting it...

Abstract

The invention aims to provide an oscillation impact damping device for liquid goods carrying. By means of the oscillation impact damping device, the angle does not need to be increased for oscillation reduction for a cargo space, and reduction of locating capacity is avoided, the effect of lowering the oscillation impact can be achieved flexibly under the condition of non-stand loading, and the oscillation impact damping device is used for liquid goods carrying. According to the technical scheme, the oscillation impact damping device for liquid goods carrying comprises heat preservation materials, sliding rails, connection ropes, an oscillation reduction assembly, sliding blocks and rails. The goods bin wall is provided with the heat preservation materials. The sliding rails are arranged on the four corners of the goods bin wall, and the sliding blocks in the sliding rails are connected with a main frame of the oscillation reduction assembly through the connection ropes.

Description

technical field [0001] The invention belongs to the technical field of sloshing devices, in particular to a sloshing shock reduction device used for liquid cargo transportation. Background technique [0002] The sloshing phenomenon is caused by the movement of the container caused by external force. When the excitation frequency is close to the natural frequency of liquid sloshing in the container, the liquid movement becomes violent, and the ceiling and side walls will bear a large sloshing impact, and the larger the container, the more liquid it contains, the lower the natural frequency, and the possible sloshing impact is more serious. Liquid cargo transportation, especially for liquefied gas carriers (LNG carriers) and large liquefied gas carriers (VLGC ships) used for long-distance cross-sea transportation, when carrying liquids such as liquefied gas, due to the high filling depth of the liquid tank, the tank The width is large, and the sloshing phenomenon is severe. ...
