Problems solved by technology

The cylindrical slide rail of this device is one of its shortcomings. If it is too thin and flexible, it will easily cause rail deformation and hinder the function of the swing control device. Board movement can cause damage to its ends; another disadvantage is that the floating board is bulky, which greatly reduces the cargo capacity of the tank

Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] For ease of description, the swaying device is applied to a rectangular liquid tank to describe the technical solution according to the present invention. However, it should be noted that the floating opening sloshing device according to the technical solution of the present invention is not only suitable for rectangular tanks, but also suitable for tanks of other shapes, such as prismatic tanks and the like.

[0026] In order to solve the above technical problems, the first embodiment of the present invention provides a sloshing control device for liquid tanks, such as figure 1 and figure 2 As shown, including floating plate 2 and slide rail 3;

[0027] The slide rails 3 are vertically arranged on both sides of the width direction of the ...

Abstract

The invention provides a sloshing and swashing device used for a liquid tank, and the liquid tank with the sloshing and swashing device.The sloshing and swashing device comprises a floating plate and slide rails.The slide rails are vertically arranged on the two sides, in the width direction, in the liquid tank.The plane composed of the two slide rails is perpendicular to the longitudinal axis of the liquid tank.The floating plate is vertically arranged and embedded in the slide rails and can slide up and down along the slide rails.A plurality of through holes for liquid to pass through are formed in the floating plate in the thickness direction.By means of the design, the problems that an existing sloshing and swashing device is large in size and prone to damage are solved, installation is easy, and the sloshing and swashing device is suitable for most of liquid tanks.

Description

technical field [0001] The invention relates to the technical field of liquid transportation, in particular to a liquid tank and a sloshing control device inside it. Background technique [0002] Sloshing is the fluctuation of the free liquid surface in the liquid-carrying tank under external excitation. It is strongly nonlinear and random. When the external excitation frequency is close to the natural frequency of the free liquid surface, the liquid in the tank will resonate, especially when it is close to the first-order natural frequency of the free liquid surface, the sloshing is the most violent, and at the same time, the huge impact pressure on the bulkhead will affect the tank. The safety of the wall structure has a very large impact. In order to prevent violent sloshing of the liquid in the tank under partial loading, all major classification societies have put forward requirements for the liquid loading rate of the LNG film type tank: under full load voyage, the l...
