Description

Technical Field

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

[0002] Natural gas refers to a mixture of hydrocarbons and non-hydrocarbon gases naturally stored in the strata. The main use of natural gas is as a fuel. It can be used to make carbon black, chemicals and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry. Storage tanks are needed to store natural gas. Due to the particularity of natural gas, protective structures are needed to prevent external factors from colliding with the storage tanks during its storage.

[0003] The existing protective structure limits the storage tank in the protective process by means of a driving mechanism cooperating with a clamping mechanism to prevent the storage tank from tipping over. However, when encountering a collision, the force generated by the vibration will still be transmitted to the storage tank, causing the sealing port of the storage tank to loosen, thereby causing natural gas leakage or even explosion. Secondly, it does not have an alarm function, and it is impossible to notify external staff in the first time and deal with it. Therefore, we provide a protective structure for a natural gas storage device. Utility Model Content
