Assembled outer floating disc for storage tank

Abstract

The invention discloses an assembled outer floating disc for a storage tank, which comprises a cabin and a middle floating disc, six main girders are distributed in an angle of 60 degrees and are connected with an inner ring girder so as to form a net structure, a cabin cover plate is connected with a seal rubber band, a bottom reinforcing rib of the cabin is connected with a bottom reinforcing rib of the inner ring girder, supporting legs of the cabin are connected to the bottom reinforcing ribs, an outer ring girder and angle steel of the outer ring are connected with a cabin floater of thecabin cover plate, the cabin floater is in a trapezoidal shape and is connected with the L-shaped and T-shaped reinforcing ribs, both ends of the cabin floater are provided with plugs, a middle floater cover plate is connected with the U-shaped reinforcing rib and the inner ring girder, and movable hinge supporting legs are fixed on the cover plate of the middle floating disc. The outer floating disc adopts the trapezoidal structure of a steel plate so as to increase the buoyancy and the strength and is suitable for the welding construction, the total weight of the outer floating disc is lightened so as to save steel by over 100 tons, otherwise, the outer floating disc is provided with the movable hinge supporting legs so as to keep the balance of the buoyancy and can not decline, and thesupporting legs can prevent lightning strike accidents.

Description

technical field [0001] The invention relates to an assembled outer floating plate for a storage tank, which is used for storing and transporting petroleum substances, and belongs to the field of large containers Background technique [0002] Usually, the storage tank is equipped with a floating plate (also known as the cabin), which can prevent the oil from polluting and deteriorating, and can also reduce the loss of oil evaporation. The traditional external floating plate is welded by steel plates, and the welding is often deformed. The cover plate is easy to Damaged by puddles, the center of gravity of the floating plate shifts due to the influence of wind and snow, causing the chuck to sink. At the same time, this structure is prone to lightning strikes and fires. [0003] CN200720154288.3 patent, it is composed of the middle floating plate and the surrounding cabin, the middle floating plate is injection molded by U-shaped buoy, fixed on the metal skeleton and the inner ...

Problems solved by technology

[0005] In addition, the above-mentioned patents and their major shortcomings cannot meet the specification requirements once the central drain pipe is blocked and the drainage fails.

There is a danger of sinking the floating plate, and the on-site construction, although the amount is smaller than the old floating plate, the outdoor workload is still relatively large
