Description

Technical Field

[0001] This utility model relates to the field of storage technology, and more specifically, to a liquefied natural gas storage and transportation device. Background Technology

[0002] Liquefied natural gas (LNG), primarily composed of methane, is widely recognized as the cleanest fossil fuel on Earth. Colorless, odorless, non-toxic, and non-corrosive, LNG requires storage tanks for storage. For example, patent application CN201510559022.6 describes an LNG transport and storage tank, comprising an inner tank and an outer tank with a sealed vacuum insulation layer between them. It includes two pressure gauges to monitor the pressure inside the inner tank in real time, providing double protection. A vacuum detection and control device ensures the vacuum insulation of the interlayer, preventing the inner tank from becoming too hot and posing a safety hazard. A liquid circulation pipeline prevents vortex formation. A liquid level detection device is included. An inert gas inlet and an exhaust port are also provided. However, in this technical solution, multiple storage tanks are transported simultaneously after storing the LNG. During transport, collisions between these tanks can occur, leading to damage and potential safety hazards. Utility Model Content

[0003] The main purpose of this utility model is to provide a liquefied natural gas storage and transportation device that can effectively solve the problem in the background technology where several storage tanks collide during transportation, resulting in damage to the storage tanks and safety hazards.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a liquefied natural gas storage and transportation device, including a stainless steel inner liner, an outer shell provided on the circumference of the stainless steel inner liner, glass wool provided between the stainless steel inner liner and the outer shell, a liquid inlet provided on the circumference of the stainless steel inner liner, a liquid outlet provided on one end surface of the stainless steel inner liner, a limit ring installed on the circumference of the outer shell, and a positioning component provided on the limit ring.

[0005] Preferably, the positioning component includes a mounting hole and a groove, the mounting hole being formed on one side surface of the limiting ring and the groove being formed on the other side surface of the limiting ring.

[0006] Preferably, a positioning post is slidably mounted through the inner wall of the mounting hole, a top plate is fixedly mounted at one end of the positioning post, a return spring is fixedly mounted on the surface of the top plate, and one end of the return spring is disposed on the surface of the limiting ring.

[0007] Preferably, a rotating shaft is rotatably installed between the inner walls on both sides of the groove, an mounting sleeve is fixedly installed on the circumference of the rotating shaft, and a sliding rod is slidably installed inside the mounting sleeve, with the sliding rod disposed inside the mounting hole.

[0008] Preferably, a positioning hole is provided through the circumference of the slide bar, and the other end of the positioning post is disposed inside the positioning hole.

[0009] Preferably, a threaded sleeve is installed on the inner wall of the groove, and a screw is installed on the inner wall of the groove through the threaded sleeve, with one end of the screw located inside the positioning hole.

[0010] Preferably, two support frames are fixedly installed on the lower circumferential surface of the outer shell.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) When several of these devices are stored side by side, the mounting sleeve is rotated by the working swing to make the mounting sleeve vertical, and at the same time the slide rod is also rotated to a vertical position. Then, the positioning column is pulled by the worker to disengage from the mounting hole. Then, the slide rod is slidably placed inside the mounting hole by the worker. Then, the positioning column is released by the worker, and the elasticity of the return spring allows the positioning column to return to the positioning hole. Then, the slide rod is fixed inside the mounting hole. At this time, the devices arranged together can be connected together by the mounting sleeve and the slide rod, so that several storage devices can maintain a certain distance between them. This can prevent the storage devices from colliding and causing damage during transportation, thus preventing installation accidents and ensuring the safety performance of the device.

Detailed Implementation

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1 , 2 As shown in Figure 3, a liquefied natural gas storage and transportation device includes a stainless steel inner liner 8, an outer shell 1 is provided on the circumference of the stainless steel inner liner 8, glass wool 7 is provided between the stainless steel inner liner 8 and the outer shell 1, a liquid inlet 4 is provided on the circumference of the stainless steel inner liner 8, a liquid outlet 5 is provided on one end surface of the stainless steel inner liner 8, a limiting ring 2 is installed on the circumference of the outer shell 1, and a positioning component 3 is provided on the limiting ring 2.

[0021] like Figure 2 , 3As shown in Figures 4 and 5, the positioning component 3 includes a mounting hole 301 and a groove 305. The mounting hole 301 is formed on one side surface of the limiting ring 2, and the groove 305 is formed on the other side surface of the limiting ring 2. A positioning post 303 is slidably mounted through the inner wall of the mounting hole 301. A top plate 304 is fixedly mounted on one end of the positioning post 303. A return spring 302 is fixedly mounted on the surface of the top plate 304. One end of the return spring 302 is disposed on the surface of the limiting ring 2. The groove 305 is located between the inner walls of the two sides. A rotating shaft 308 is rotatably mounted, and a mounting sleeve 309 is fixedly mounted on the circumference of the rotating shaft 308. A sliding rod 310 is slidably mounted inside the mounting sleeve 309. The sliding rod 310 is disposed inside the mounting hole 301, and a positioning hole 311 is formed through the circumference of the sliding rod 310. The other end of a positioning post 303 is disposed inside the positioning hole 311. A threaded sleeve 306 is installed on the inner wall of the groove 305, and a screw 307 is installed on the inner wall of the groove 305 through the threaded sleeve 306. One end of the screw 307... When several of these devices are stored side-by-side inside the positioning hole 311, the mounting sleeve 309 is rotated by a swinging motion to a vertical position, which in turn swings the sliding rod 310 to a vertical position. Then, the operator pulls the positioning pin 303 to detach it from the mounting hole 301. The operator then slides the sliding rod 310 to slide it into the mounting hole 301. Finally, the operator releases the positioning pin 303, and the elasticity of the return spring 302 returns it to the positioning hole 311, thus fixing the sliding rod 310 inside the mounting hole 301. This connects the devices arranged together via the mounting sleeve 309 and the sliding rod 310, maintaining a certain distance between the storage devices. This prevents collisions and damage during transportation, ensuring the safety of the device.

[0022] like Figure 1 As shown, two support frames 6 are fixedly installed on the lower circumference of the outer shell 1, which can support the device.

[0023] The working principle of this liquefied natural gas storage and transportation equipment:

[0024] In use, the glass wool 7 placed between the stainless steel inner liner 8 and the outer shell 1 improves the insulation of the device, making it easier to store liquefied natural gas. When transporting the device and storing several units side by side, the mounting sleeve 309 is rotated vertically by a swinging motion, which simultaneously swings the sliding rod 310 vertically. Then, the operator pulls the positioning pin 303 to disengage it from the mounting hole 301. Finally, the operator slides the sliding rod 310 to set it in place on the mounting plate. Inside hole 301, when the operator releases the positioning post 303, the elasticity of the return spring 302 allows the positioning post 303 to return to the positioning hole 311. At this point, the slide rod 310 can be fixed inside the mounting hole 301. The devices arranged together can then be connected to the slide rod 310 via the mounting sleeve 309, maintaining a certain distance between the storage devices. This prevents collisions between the storage devices during transportation, thus avoiding damage and installation accidents, and ensuring the safety performance of the device.

[0025] The above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
