Description

Technical Field

[0001] The utility model relates to the technical field of liquefied natural gas, in particular to a liquefied natural gas storage and transportation device. Background Art

[0002] LNG storage and transportation facilities play an important role in energy transportation, storage and export. They enable natural gas to be effectively transported to various regions in liquid form, realizing the cross-border flow of energy resources. At the same time, LNG occupies a relatively small space, making storage and balancing supply and demand more convenient. For countries or regions with abundant natural gas resources, LNG facilities are an important means to achieve natural gas exports.

[0003] During the storage and transportation of liquefied natural gas, it is necessary to use storage tanks to store it. In order to improve the safety of the use of storage tanks, brackets are usually configured to fix the storage tanks. The traditional bracket structure is simple and cannot be flexibly adjusted according to the specifications of the storage tanks. This leads to the inability to guarantee the stability of the storage tanks during actual use, which in turn affects the safety of use. There are certain deficiencies in its use. For this reason, we propose a liquefied natural gas storage and transportation device. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-3A liquefied natural gas storage and transportation device includes a base 1 and a storage tank 4. A lifting mechanism 2 is installed on the top of the base 1, and a support frame mechanism 3 is installed on the side of the lifting mechanism 2. The lifting mechanism 2 is used to adjust the height of the support frame mechanism 3, and the support frame mechanism 3 is used to clamp and fix the storage tank 4. The lifting mechanism 2 includes a guide shaft 21 and a threaded column 22 fixed on the base 1. The threaded column 22 is connected with a first threaded sleeve 23 through a thread. The first threaded sleeve 23 is rotatably connected with a shell 24. The first threaded sleeve 23 is fixedly sleeved with a first bevel gear 25. The shell 24 is slidably connected to the guide shaft 21. A first adjusting rod 26 is installed on the side of the shell 24. The first adjusting rod 26 is inserted into the interior of the shell 24 and is connected to a second bevel gear 27. The first bevel gear 25 and the second bevel gear 27 are meshed transmission. The support frame mechanism 3 is installed on the side of the shell 24. The support frame mechanism 3 includes a guide shaft 21 fixed on the base 1 and a threaded column 22. The threaded column 22 is connected with a first threaded sleeve 23 through a thread. The first threaded sleeve 23 is rotatably connected with a shell 24. The first threaded sleeve 23 is fixedly sleeved with a first bevel gear 25. The shell 24 is slidably connected to the guide shaft 21. A first adjusting rod 26 is installed on the side of the shell 24. The first adjusting rod 26 is inserted into the interior of the shell 24 and is connected to a second bevel gear 27. The first bevel gear 25 and the second bevel gear 27 are meshed transmission. The movable frame 31 on the side of the body 24 has a slide groove 32 on the side of the movable frame 31. Fixed plates 33 are fixed at both ends of the slide groove 32. A screw rod 34 is installed between the two fixed plates 33. One end of the screw rod 34 passes through the fixed plate 33 and is connected to a second adjusting rod 35. Second threaded sleeves 36 are threadedly connected to both ends of the screw rod 34. A slider 37 is fixed on the second threaded sleeve 36. The slider 37 passes through the slide groove 32 and is connected to a movable plate 38. A clamping plate 39 is installed on the side of the movable plate 38. The threads at both ends of the screw rod 34 have opposite rotation directions. The slider 37 is slidably connected to the slide groove 32. The side opposite to the clamping plate 39 is an arc-shaped structure. When in use, the storage tank is fixed by the clamping plate with adjustable distance in the support frame mechanism, thereby improving the stability of the storage tank installation. At the same time, the height of the support frame mechanism is adjusted by the lifting mechanism to facilitate the use of storage tanks of different specifications. The flexibility of use is very high.

[0019] When in use, the base 1 is fixed on the transport vehicle, and the storage tank filled with liquefied gas passes through the movable frame 31 and is clamped with the base 1. Then the second adjusting rod 35 is rotated, and the second adjusting rod 35 drives the screw rod 34 to rotate. The screw rod 34 drives the slider 37 to slide in the slide groove 32 through the thread transmission with the second threaded sleeve 36. The slider 37 drives the movable plate 38. Since the threads at both ends of the screw rod 34 have opposite rotation directions, the two movable plates 38 move in opposite directions. The two movable plates 38 drive the clamping plate 39, and the clamping plate 39 is close to the storage tank 4 to complete the clamping and fixing of the storage tank 4 to meet the needs of different widths. The storage tank 4 is fixed. When the storage tank 4 at different heights is used, the first adjusting rod 26 is rotated, and the first adjusting rod 26 drives the second bevel gear 27 to rotate. The second bevel gear 27 drives the first threaded sleeve 23 to rotate through the meshing transmission with the first bevel gear 25. The first threaded sleeve 23 drives the shell 24 to slide on the guide shaft 21 through the threaded transmission with the threaded column 22, and the height of the shell 24 is adjusted. Then the shell 24 drives the support frame mechanism 3, and the height of the support frame mechanism 3 is adjusted to meet the installation of storage tanks 4 at different heights. The device has a simple structure and is very flexible to use.

[0020] To sum up, compared with the prior art, the utility model, when in use, utilizes the clamping plate with adjustable distance in the support frame mechanism to fix the storage tank, thereby improving the stability of the storage tank installation, and at the same time utilizes the lifting mechanism to adjust the height of the support frame mechanism to facilitate the use of storage tanks of different specifications, and the flexibility of use is very high.
