Ceiling type flexible oil storage structure suitable for open sea island reef

Abstract

The invention relates to a ceiling type flexible oil storage structure suitable for an open sea island reef. The ceiling type flexible oil storage structure comprises a flexible oil bag, a binding belt, a concrete ceiling, a horizontal anchor chain, a ground anchor, an oil delivering pipe, an oil delivering pipeline and a breakwater. The breakwater is arranged on an open sea and used for reducing power loads brought by sea waves so as to guarantee safety and stability of the structure. The ground anchor is vertically arranged on the seabed between the breakwater and the island reef. A frame of the concrete ceiling is in anchoring connection with the ground anchor on the seabed. The binding belt is fixedly arranged on the surface of the flexible oil bag. The flexible oil bag is fixedly arranged in seawater below the concrete ceiling through the binding belt and the horizontal anchor chain. An oil outlet is formed in the upper portion of the flexible oil bag and connected with the oil delivering pipe. The oil delivering pipe is connected with the oil delivering pipeline arranged in the island reef. The upper portion of the oil delivering pipeline stretches out of the surface of the island reef and is provided with an oil injection port and an oil discharging valve. According to the flexible oil bag, a large amount of land space is saved, the advantages of underwater fire prevention, lightning protection, explosion prevention, evaporation prevention and the like are brought into full play, and the economic cost of construction of matched oil storage facilities is greatly reduced.

Description

technical field [0001] The invention relates to the field of oil storage, in particular to a roof-type flexible oil storage structure suitable for offshore islands and reefs. Background technique [0002] Nowadays, most oil products in our country are stored in oil tanks. In terms of storage area, it mainly includes onshore oil tanks and underwater oil tanks. Onshore oil tanks have low investment, fast construction, and convenient management and maintenance. However, building oil storage tanks on the urban surface requires a large amount of land, which requires high land space, high cost, short service life, and high operating costs. The danger is great. At the same time, because the oil tank needs to rely on its own rigidity to resist its internal oil pressure, it also needs external power to realize the oil filling and discharging, which is very time-consuming and laborious; the oil tank has high requirements on materials, and the cost is very expensive. The danger of f...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a roof-type flexible oil storage structure suitable for offshore islands and reefs in view of the above-mentioned shortcomings of the existing underwater oil storage, which not only has fireproof and explosion-proof underwater rigid oil storage tanks, but also is safe and concealed. , The advantages of saving floor space can also make up for the problems of high pressure and high cost of rigid oil storage tanks, high requirements for corrosion resistance, strength, rigidity and durability of the tank body, complex construction and maintenance management, and can also realize unpowered automatic Oil injection and oil discharge greatly reduce the economic cost of the construction of supporting oil storage facilities
