Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

As shown in fig. 1, a LNG cryogenic storage jar with damper, including the jar body that has conveying pipeline 1, jar body is including outer jar 2 and inner tank 3 that the interval set up, and LNG liquid storage is in the inside of inner tank 3, the inside of inner tank 3 still is equipped with damper, damper is including having elastic first mesh plate 4 and second mesh plate 5, the last lateral wall of inner tank 3 is located along the length direction interval of inner tank 3 to first mesh plate 4, and is a plurality of the one end of first mesh plate 4 with there is the clearance between the lower lateral wall of inner tank 3, the lower lateral wall of inner tank 3 is located along the length direction interval of inner tank 3 to second mesh plate 5, and is a plurality of the one end of second mesh plate 5 with there is the space, a plurality of between the last lateral wall of inner tank 3 first mesh plate 4 and a plurality of second mesh plate 5 dislocation set. The first mesh plate 4 and the second mesh plate 5 are arranged in a staggered mode, namely, a second mesh plate 5 is arranged between any two first mesh plates 4 or a first mesh plate 4 is arranged between any two second mesh plates 5, so that when the LNG liquid in the inner tank 3 shakes in the horizontal direction in the driving process of a vehicle, one part of the LNG liquid can directly penetrate through the first mesh plate 4 and the second mesh plate 5, and the other part of the LNG liquid can impact the first mesh plate 4 and the second mesh plate 5, so that the first mesh plate 4 and the second mesh plate 5 with elasticity deform, and the impact of the LNG liquid shaking on the inner tank 3 is effectively counteracted; further, first mesh plate 4 and the lower lateral wall contactless of inner tank 3, second mesh plate 5 and the last lateral wall contactless of inner tank 3 for first mesh plate 4 and second mesh plate 5 homoenergetic produce great elastic deformation, further improve and rock the absorbing action of impact energy to LNG liquid, realize the reliable energy-absorbing shock attenuation to inner tank 3 and outer jar 2, rational in infrastructure, the shock attenuation effect is showing.

Be equipped with two springs 6 between adjacent first mesh board 4 and the second mesh board 5, one the lateral wall of the one end of first mesh board 4, the lateral wall of second mesh board 5 are connected to the opposite side of one side connection of spring 6, another the lateral wall of the one end of second mesh board 5, the lateral wall of first mesh board 4 are connected to the opposite side of one side connection of spring 6. Through the setting of a plurality of springs 6, play the limiting displacement to the elastic deformation of first mesh board 4 and second mesh board 5 on the one hand, prevent that first mesh board 4 and second mesh board 5 from damaging because of the deformation volume is too big, on the other hand can directly absorb LNG liquid and rock the shock energy when spring 6 is through tensile or compression in order to realize the limiting displacement to the elastic deformation of first mesh board 4 and second mesh board 5, further improve shock attenuation effect.
