Description

Technical Field

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

[0002] Liquefied natural gas refers to natural gas that is cooled to below its freezing point and converted into liquid form for storage and transportation. As a clean energy source, liquefied natural gas plays an important role in the energy industry. Storage tanks are required for the transportation and storage of liquefied natural gas.

[0003] For example, a Chinese patent discloses: a liquefied natural gas storage and transportation tank, announcement number: CN211371908U, which is equipped with an alarm, a waterstop, a partition plate, contacts and an insulating plate. When the waterstop expands when encountering water, the insulating plate can be pushed outward, so that the contacts on one side of the two insulating plates approach each other until they are squeezed and contacted with each other. Therefore, the battery, the alarm and the two contacts form a closed circuit, and an alarm sound is issued to remind the transportation personnel that a leakage has occurred.

[0004] However, in the process of implementing the above technical solutions, it was found that at least the following technical problems exist: since the storage and transportation tanks are mostly designed to be cylindrical in shape, during transportation, as the vehicle turns and accelerates and decelerates, the liquefied natural gas will shake and vibrate in the tank, causing the tank body to move and bump, affecting the stability of the liquefied natural gas storage tank, which is not conducive to safe transportation. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides a fixing device for a liquefied natural gas storage and transportation tank, which solves the technical problem that since most storage and transportation tanks are designed to be cylindrical in shape, during transportation, as the vehicle turns and accelerates and decelerates, the liquefied natural gas will shake and vibrate in the tank, causing the tank body to shift and bump, affecting the stability of the liquefied natural gas storage tank and being unfavorable for safe transportation.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A liquefied natural gas storage and transportation tank fixing device comprises a bearing platform, the upper end of the bearing platform is movably connected to the storage and transportation tank body, the upper end of the storage and transportation tank body is fixedly connected to a lifting ring, and is characterized in that two limit blocks are clamped inside the bearing platform, and sliding blocks are slidably connected inside the two limit blocks, and anti-leakage mechanisms are sleeved inside the two limit blocks, and the anti-leakage mechanism includes two weight sensors, and the two weight sensors are sleeved inside the two limit blocks.

[0010] Preferably, a motor is fixedly connected to the upper end of the supporting platform.

[0011] Preferably, a synchronous belt is sleeved on the outer surface of the motor, and the upper end of the bearing platform is fixedly connected to two connecting seats.

[0012] Preferably, two bidirectional threaded rods are rotatably connected inside the two connecting seats.

[0013] Preferably, the outer surface of the bidirectional threaded rod is threadedly connected with two sliding plates.

[0014] Preferably, two polished rods are fixedly connected to opposite ends of the two connecting seats.

[0015] Preferably, one opposite end of the two sliding plates is fixedly connected with a clamping block.

[0016] Preferably, outer surfaces of the two polished rods are sleeved with rubber pads.

[0017] (III) Beneficial effects

[0018] 1. After the storage tank body is placed, start the motor. The motor drives the two-way threaded rod to rotate through the synchronous belt. During the rotation of the two-way threaded rod, the threaded connection drives the two sliding plates to slide inward, and the storage tank body is clamped and fixed by two clamping blocks to ensure that the liquid storage tank remains stable during transportation, reduce tilting and sliding caused by bumps or other external factors, and ensure safety during transportation.

[0019] 2. Carry and place the storage tank body inside the limit block. After the storage tank body is in place, squeeze the sliding block downward to slide. The sliding block slides to the weight sensor. The overall weight of the storage tank body is obtained through the weight sensor, which is convenient for detecting the weight status of the storage tank body during transportation. By observing the weight change, it is possible to determine whether the storage tank body is leaking and deal with it in time to enhance safety during transportation.

After the storage and transportation tank body is placed, the motor is started, and the motor drives the two-way threaded rod to rotate through a synchronous belt. During the rotation of the two-way threaded rod, the threaded connection drives the two sliding plates to slide inward, and the storage and transportation tank body is clamped and fixed by two clamping blocks, ensuring that the liquid storage tank remains stable during transportation, reducing tilting and sliding caused by bumps or other external factors, and ensuring safety during transportation.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that since most storage tanks are designed to be cylindrical in shape, during transportation, as the vehicle turns and accelerates and decelerates, the liquefied natural gas will shake and vibrate in the tank, causing the tank body to shift and bump, affecting the stability of the liquefied natural gas storage tank, and being unfavorable for safe transportation.

In the process of placing and fixing the storage tank body 12, the two limit blocks 14 are used to limit and fix it in the length direction.

After the storage tank body 12 is placed in place, the sliding block 15 is pressed downward to slide, and the sliding block 15 slides to the weight sensor 16. The overall weight of the storage tank body 12 is obtained through the weight sensor 16, which is convenient for detecting the weight status of the storage tank body 12 during transportation. By observing the weight change, it is possible to determine whether the storage tank body 12 leaks and deal with it in time to enhance the safety during transportation. In the process of placing and fixing the storage tank body 12, the two limit blocks 14 are used to limit and fix it in the length direction.
