Description

Technical Field

[0001] The utility model relates to the technical field of liquefied natural gas storage tanks, in particular to a vibration-proof buffer device for a liquefied natural gas storage tank. Background Art

[0002] The application background of liquefied natural gas storage tank vibration damping devices is mainly to enhance the structural stability and vibration resistance of the tank to cope with external vibration and impact, and ensure the safe operation of the tank. This device is commonly used in liquefied natural gas storage and transportation systems to ensure that the tank can operate safely and reliably in various environmental conditions.

[0003] Existing liquefied natural gas storage tanks are usually equipped with a fixed seat and a support plate at the lower end to provide support for the storage tank. However, when an external object collides with the storage tank, the vibration caused will cause the liquid natural gas in the storage tank to shake, which poses a major safety hazard. In addition, there is no buffer structure, and the storage tank has poor stability, which is prone to shaking during transportation and storage. Utility Model Content

[0004] (1) Technical problems solved

A limit plate is provided at the end of the fixed column away from the storage tank, and a telescopic cylinder is slidably sleeved on the circumferential outer wall. A clamping seat is provided at the end of the telescopic cylinder close to the fixed column and engaged with the limit plate. A fixing plate is provided at the end away from the fixed column. Several fixing holes are reserved on the fixing plate. Fixing bolts pass through the fixing holes to fix the fixing plate to the inner side of the baffle. A telescopic spring is fixedly connected between the inner side and the fixing column.

[0013] As an improvement, a climbing frame is fixed to the right end of the storage tank.

[0014] As an improvement, a pair of hangers distributed on the left and right are provided on the top of the storage tank, and a foldable inspection cylinder cover is provided in the middle.

[0015] (3) Beneficial effects

[0016] The advantages of this utility model compared with the prior art are:

[0017] The baffle can block the colliding objects outside the storage tank, preventing the colliding objects from colliding with the main body and reducing the vibration effect.

[0025] In the description of the present invention, it should be understood that the terms "center", "lateral", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variations thereof are intended to cover non-exclusive inclusions.

[0026] The present invention will be described in further detail below with reference to the accompanying drawings.

[0027] Please see the attached Figure 1 To the attached Figure 6 As shown, it includes a storage tank 1, a climbing frame 13 is fixed to the right end of the storage tank 1, a pair of hangers 14 distributed left and right are provided at the top, a foldable inspection cylinder cover 15 is provided in the middle of the top, and several support seats 2 are provided at the bottom end of the storage tank 1. The bottom end of the support seat 2 is fixed to the top surface of the bottom plate 3, and fixed columns 4 are fixed on the front and rear sides. The end of the fixed column 4 away from the storage tank 1 is provided with a limit plate 9, and the circumferential outer wall is slidably sleeved with a telescopic cylinder 5. The fixed column 4 is provided with a pair distributed up and down, and the circumferential outer wall of the fixed column 4 is slidably connected to the circumferential inner wall of the telescopic cylinder 5. The end of the telescopic cylinder 5 close to the fixed column 4 is provided with a card seat 10 that cooperates with the limit plate 9, and the end away from the fixed column 4 is provided with a fixed plate 6. Several fixing holes are reserved on the fixed plate 6, and the fixing bolts pass through the fixing holes to fix the fixed plate 6 to the inner side of the baffle 7. A telescopic spring 8 is fixedly connected between the inner side and the fixed column 4.

[0028] Please see the attached Figure 3 , Attachment Figure 5 As shown, a buffer pad 11 is provided on the outer side of the baffle 7, and the buffer pad 11 is fixed to the baffle 7 by strong glue. A plurality of evenly distributed buffer air cushion balls 12 are provided on the outer side of the buffer pad 11. The buffer air cushion balls 12 are semicircular air cushion structures with air holes that protrude toward the outer end.

[0029] Through the above structure, the support seat 2 at the bottom end of the storage tank 1 cooperates with the fixed column, the telescopic cylinder 5 and the telescopic spring 8, and the baffle 7 can perform buffering and contraction to isolate the colliding object outside the storage tank 1, prevent the storage tank body from being impacted and causing vibration, and improve the safety of the storage tank 1. The buffer pad 11 on the baffle 7 cooperates with the buffer air cushion ball 12 to effectively reduce the impact force of the colliding object on the storage tank 1, and has excellent buffering performance.

[0030] During the specific implementation of the present utility model: when the storage tank 1 is hit by an external object, the baffle 7 is squeezed, driving the telescopic cylinder 5 to move toward the fixed column 4. Since the fixed column 4 and the fixed plate 6 are fixedly connected with a telescopic spring 8, the baffle 6 gradually stops under the compression of the spring during the movement, preventing the storage tank body from being hit and causing vibration, thereby improving the safety of the storage tank 1. The buffer pad 11 on the baffle 7 cooperates with the buffer air cushion ball 12 to effectively reduce the impact force of the collision object on the storage tank 1, and has excellent buffering performance.

[0031] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without creatively designing a structure and embodiment similar to the technical solution, they shall fall within the scope of protection of the present invention.
