Abstract
The utility model provides a device is swung to system of C type LNG tank, belongs to ocean engineering LNG storage and transport technologies field. This system is swung the device and is included that C type LNG tank and two systems swing the ring, and the ring is swung respectively through connecting intermediate position that the gasket used C type LNG tank as symmetrical arrangement and fix on the inner wall of C type LNG tank to two systems, and the system is swung the ring and is adopted the conical ring column structure, at the bottom of the awl of conical ring column structure diameter and C type LNG tank the internal diameter unanimously, the vertex of a cone hole of conical ring column structure is towards the intermediate position of C type LNG tank. Connecting the gasket and adopting the square steel sheet that has a dog -ear, connect the one end of gasket and connect C type LNG tank, the other end is connected the system and is swung the ring. This system is swung system that the device adopted a simple structure and is swung the ring, and it is obvious that the effect is swung to the system, is applicable to the suppression of rocking load in the C type LNG cargo tank.
Description
Technical field
The system that the utility model relates to a kind of C type LNG liquid tank swings device, belongs to ocean engineering LNG and stores and technical field of transportation.
Background technology
When the liquid in LNG ship oceangoing ship independence C type cargo hold is not filled, when LNG ship oceangoing ship navigates by water in wave, can there is sloshing phenomenon in the liquid in cabin.Strong rocking directly can cause serious average pollution incident, and for the independent C type cargo hold longitudinally arranged, when pitch frequency close to boats and ships of the natural frequency of liquid sloshing, rocking and pitching motion generation resonance of liquid, thus cause producing independent C type cargo hold bulkhead very large rocking impact, because this rocks impact, the parts forming this independent C type cargo hold may be damaged.Inevitably there is above-mentioned sloshing phenomenon due to the motion of the LNG ship oceangoing ship in ocean, therefore LNG ship oceangoing ship rock concern and the attention that safety problem is subject to all circles.Swinging device in the liquid tank inside system of installing is the effective ways that load is rocked in a kind of suppression.
At present, usually play by the cabin inner member such as ring stiffener of inside the effect suppressing to rock in C type LNG liquid tank, and for carrier fluid rate may fully loaded with zero load between the LNG that changes arbitrarily to annotate ship, thisly serve as by component system that system swings device and swing effect and be restricted, this situation needs to install special system and swings device.Although it is simple that traditional system swings the version that device has, system swings limited efficiency; Although the system had swings successful, version is too complicated, is unfavorable for manufacturing, installing and cleaning.Therefore, design a kind of structure relatively simple, be convenient to install, safeguard and cleaning, and have the system that obviously system swings effect and swing device, this suppresses significant for rocking of C type LNG liquid tank.
Summary of the invention
In order to overcome problems of the prior art, the utility model provides a kind of system of C type LNG liquid tank to swing device, and this system is swung device and adopted a kind of structure simply to make to swing ring, and system swings successful, is applicable to the suppression of rocking load in C type LNG cargo tank.
The technical solution adopted in the utility model is: a kind of system of C type LNG liquid tank swings device, it comprises C type LNG liquid tank, it also comprises two systems and swings ring, it is be arranged symmetrically with and be fixed on the inwall of C type LNG liquid tank with the midway location of C type LNG liquid tank that described two systems swing ring respectively by attachment spacers, described system is swung ring and is adopted tapered annular structure, the cone bottom diameter of tapered annular structure is consistent with the internal diameter of C type LNG liquid tank, and the vertex of a cone hole of tapered annular structure is towards the midway location of C type LNG liquid tank; Described attachment spacers adopts the square plate with a knuckle, and attachment spacers is provided with two circular holes, and a circular hole adopts bolt to be fixedly connected with C type LNG liquid tank, and another circular hole adopts bolt to swing ring with system and is fixedly connected with.
Described two systems distance of swinging between ring is 0.37 times of C type LNG liquid tank total length, the cone apex angle that described system swings ring is 70-80 degree angle, the cone length of side is 0.21 times of C type LNG liquid tank internal diameter, and each system is swung ring and adopted four attachment spacers be distributed on C type LNG liquid tank inwall.
Described system is swung ring and is adopted polymethyl methacrylate or PMMA to make.
The beneficial effects of the utility model are: this system is swung device and comprised C type LNG liquid tank and two systems swing ring, it is be arranged symmetrically with and be fixed on the inwall of C type LNG liquid tank with the midway location of C type LNG liquid tank that two systems swing ring respectively by attachment spacers, system is swung ring and is adopted tapered annular structure, the cone bottom diameter of tapered annular structure is consistent with the internal diameter of C type LNG liquid tank, and the vertex of a cone hole of tapered annular structure is towards the midway location of C type LNG liquid tank.Attachment spacers adopts the square plate with a knuckle, and one end of attachment spacers connects C type LNG liquid tank, and the other end connects system and swings ring.This system is swung device and is adopted a kind of structure simply to make to swing ring, and system swings successful, is applicable to the suppression of rocking load in C type LNG cargo tank.
