[0002] After oil extraction, the extracted oil will be stored in the storage tank first, and then the oil will be refined and processed. The storage tank is made of low-alloy steel material. Low-alloy steel has the characteristics of high strength and good plastic toughness. Because the oil storage tank is in On the offshore drilling platform, the sea air has high humidity and salt content, and the storage tank is exposed to the high-humidity marine atmospheric environment for a long time. The moisture and salt in the atmosphere will condense on the surface of the storage tank to form a water film, which acts as an electrolyte. , it is easy to electrochemically corrode the low-alloy steel material on the surface of the storage tank, and it is easy to corrode and rust the low-alloy steel in a high-humidity environment for a long time, requiring frequent maintenance and affecting the use of the storage tank

Embodiment 1
[0025] Such as Figure 1-Figure 6 Shown:
[0026] The present invention is an offshore oil storage tank, the structure of which includes a guardrail 1, an oil suction pipeline 2, an oil outlet pipe 3, and a storage tank 4. The oil suction pipeline 2 is embedded and installed on the side of the storage tank 4. The storage tank 4 is an integrated structure, the guardrail 1 is welded on the upper end of the storage tank 4, the storage tank 4 is provided with a protective mechanism 41 and a storage tank 42, and the protection mechanism 41 is attached to the outside of the storage tank 42. The upper end of the protection mechanism 41 is welded on the outside of the guardrail 1, and the protection mechanism 41 is in a ring structure, and is located on the same central axis as the storage tank 42, so that the storage tank 42 is sealed inside.
[0027] Wherein, the protective mechanism 41 is provided with a protective layer 411, a collecting tank 412, a sliding mechanism 413, a colle...
Embodiment 2
[0034] Such as Figure 7-Figure 8 Shown:
[0035] Wherein, the cleaning mechanism 415 is composed of a cleaning block c1, a threaded rod c2, a fan c3, a rotating rod c4, and a connection line c5. The connection line c5 is embedded in the upper end of the cleaning block c1, and the threaded rod c2 and the cleaning block c1 is threaded, the rotating rod c4 and the fan c3 are located on the same center line, the lower end of the connecting line c5 is embedded in the rotating rod c4, the cleaning block c1 is attached to the outside of the sliding mechanism 413, and the threaded rod c2 Shaft wheels are installed at both ends, so that the threaded rod c2 can be rotated, and the threaded rod c2 is prevented from rotating too fast.
[0036]Wherein, the cleaning block c1 is provided with a cleaning groove c11, a rotating blade c12, and a fixed block c13, the rotating blade c12 is installed on the right side of the fixing block c13, the cleaning groove c11 and the fixing block c13 are ...

Abstract
The invention discloses an offshore oil storage tank. The offshore oil storage tank structurally comprises a fence, an oil pumping pipeline, an oil outflow pipe and a storage tank. The storage tank isprovided with a protection mechanism and a containing tank. As water is coagulated to form water drops, the water drops stagnate in the falling and sliding process to form water films, after the water drops slide from a sliding mechanism, part of the water drops are collected on an absorption block, the water drops are prevented from stopping in the sliding process, the sliding area of the waterdrops is defined through grooves, the situation that the water films are formed as the sliding area of the water drops is too large is avoided, most of the water drops slide to a filter net through inclined linear structures on sliding strips to enter a collecting groove in the protection mechanism, the situation that the water films are formed by the water drops on the surface of the storage tankis avoided, and electrochemical corrosion of the surface of the storage tank is avoided. Shaft wheels are mounted at the two ends of a threaded rod, the threaded rod rotates, the situation that the threaded rod rotates too rapidly is avoided, salt crystals on the surface of the sliding mechanism are cleaned away through a cleaning groove in the moving process, the salt crystals are prevented fromstagnating on the surface of the storage tank, and the situation that the surface of the storage tank rusts due to salt is avoided.
