Description

Technical Field

[0001] The utility model relates to the technical field of gas tank protection, in particular to a safety buffer device for a liquefied gas storage tank. Background Art

[0002] After checking, the disclosure (announcement) number: CN2767811Y discloses a liquefied gas tank. This technology discloses "liquefied gas tank, involving the improvement of the structure of the liquefied gas tank, solving the problem that the liquid burned in the liquefied gas tank cannot be completely burned and there is residual liquid, which wastes energy. The liquefied gas tank is composed of a shell, a switch valve, a liquid guide tube, and a weight. The upper end of the liquid guide tube is connected to the switch valve, and the lower end is close to the bottom of the shell. Its advantage is that the liquid containing carbon 4 and carbon 5 in the liquefied gas tank can be completely burned without residual liquid, without wasting energy, and can also prevent explosion caused by flashback".

[0003] Liquefied gas storage tanks are widely used in industrial and civil fields to store and supply liquefied petroleum gas (LPG) and other flammable gases. Due to the special properties of liquefied gas, its storage tanks must pay great attention to safety during design and use. During transportation, installation and use, liquefied gas storage tanks may be subject to various external impacts, such as collision, dumping and vibration, which may cause leakage, explosion and other serious safety accidents. Therefore, in order to ensure the safety of liquefied gas storage tanks, effective protection and buffering measures must be taken.

[0004] However, in the prior art, traditional liquefied gas storage tank protection devices have certain deficiencies in terms of buffering and protection effects. First, the existing protection devices mostly use simple fixed brackets or shells, which cannot effectively buffer external force impacts, especially when the tank body topples over or is hit from the side, which can easily cause direct damage to the tank. Secondly, the existing protection devices usually lack a comprehensive protection mechanism and can only provide protection in a single direction or a single part, and cannot provide all-round protection for the tank. In addition, some protection devices have problems such as complex structure, inconvenient installation and maintenance in design, which affects the safety and practicality of their actual application. Therefore, we proposed a safety buffer device for liquefied gas storage tanks to improve its protection effect and safety during actual use. Utility Model Content
