Description

Technical Field

[0001] This utility model relates to the field of natural gas technology, specifically to a transportation protection device for natural gas storage tanks. Background Technology

[0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gas field gas, mud volcano gas, coalbed methane, and biogenic gas, etc.). Liquefied natural gas is natural gas that has been compressed and cooled into a liquid form. Natural gas usually needs to be liquefied before transportation and then stored and transported in storage tanks. Because natural gas is flammable and explosive, protective measures are required when transporting bottled natural gas.

[0003] A search revealed that utility model patent CN217875319U discloses a "transport protection device for a natural gas storage tank". This device includes a first slot and a second slot, both of which are located on a support block. The first and second slots limit the end of the natural gas storage tank. In use, the corners of the natural gas storage tank can be engaged with the connection between the second and first slots. The inclined surface of the second slot limits the natural gas storage tank from both sides, reducing its movement space and preventing it from sliding left or right, thus ensuring the safe operation of the natural gas storage tank.

[0004] Natural gas storage tanks are generally large and usually require cranes for installation. The protective doors of the tanks are located on the side, making the installation of natural gas storage tanks very inconvenient. Utility Model Content

When the sliding plate 56 moves to the foremost position, the first limit seat 65 and the second limit seat 66 are located outside the protection box 1. At this time, the natural gas tank can be placed between the first limit seat 65 and the second limit seat 66.

[0032] After the tank is placed, rotate the rotating plate 103 to the vertical position. Then, by rotating the handwheel 106, the threaded rod 104 can be rotated. The rotating threaded rod 104 can move along the rotating plate 103. At this time, the pressure plate 105 can press down on the natural gas tank, which can limit the natural gas tank and prevent it from shaking. During transportation, the exhaust fan 12 can be used to extract the gas inside the protective box 1. The external gas enters the protective box 1 through the filter screen 11, which can dissipate heat inside the protective box 1.
