Description

Immersion type floating disc structure

The technical field is as follows:

the floating plate belongs to the technical field of oil storage, and is an energy-saving product arranged in an oil tank. Many oil materials are volatile, and volatilization can cause economic loss and pollution and also can cause potential safety hazards. To limit oil evaporation, a floating plate device called an inner floating roof is often used in the tank. The device is a floating top cover which is made of metal and floats on the surface of the oil liquid, and the floating top cover covers the surface of the oil liquid, so that the volatilization loss of the oil product can be reduced. The floating plate in use is mostly a buoy structure and consists of a buoy and a frame covering a skin. Because there is the clearance between flotation pontoon and the skin, the oil can volatilize to it to along with the floating plate goes up and down to leak away. The immersion type floating disc is a novel structure, and because the lower part of the immersion type floating disc is a plane, the immersion liquid surface has a certain depth, so that an oil-gas space does not exist between the immersion type floating disc and oil products, volatilization is reduced, and energy saving and safety are achieved.

Background art:

the existing immersion type floating plate is most commonly used with 2 structures, one is a beam frame structure, and the other is a beamless structure. The frame structure with beams is a frame assembled by main beams and auxiliary beams, and a plurality of floating boxes are fixed in the frame side by side. The beamless structure is that the sides of the buoyancy tanks are arranged up and down, and the buoyancy tanks are connected with each other two by two through bolts. These 2 structures have different technical drawbacks: the floating plate is provided with a beam frame structure, the main beam and the auxiliary beam bear the load of the floating plate, and the frame is easy to disintegrate when the large load is applied; the upper edge and the lower edge of the floating plate bear all loads of the floating plate, the edge of the floating box can generate tearing openings due to metal fatigue in long-term operation, and the lower edge of the floating box can enable oil to enter the floating box, so that a sinking accident occurs.

The invention content is as follows:

in order to solve the above-mentioned defects, the present invention adopts the following solutions:

the whole floating plate is of a beam reinforced floating box structure. The upper plate of the buoyancy tank is in a buckle plate form, two end planes of the upper plate of the buoyancy tank extend outwards to form edges, and two sides of the upper plate of the buoyancy tank are bent upwards; the upper edges of the two sides of the buoyancy tank coincide with the bent edges of the two sides of the upper plate of the buoyancy tank. Corner connection corner connectors are welded at two ends of the lower surface of the floating box, and transverse connection corner connectors are welded at two sides of the middle of the floating box. The floating plate is provided with main beams at two ends of the length of the floating box, the edges at two ends of the upper plate of the floating box are fixed on the main beams, the side edges on the upper surface of the floating box are fixedly connected with the adjacent floating boxes through bolts, and sealing strips are also stuck between the edges. The bottom surfaces of the floating boxes are connected in the longitudinal direction by using longitudinal connecting angle codes and corner connecting angle codes which cross over the main beams, so that the bottom surfaces of the floating boxes are connected into a whole which penetrates through the floating plate in the longitudinal direction. Corner connecting angle codes at two ends of the floating boxes are also connected with corner connecting angle codes of adjacent floating boxes, so that the floating boxes are also connected into a whole in the transverse direction. And transverse connecting corner connectors and reinforcing plates are also used in the middle of the floating boxes to increase the connecting strength between the floating boxes. Especially, the use of the reinforcing plate reduces the bending stress of the transverse connecting corner brace and prevents the bottom surface of the buoyancy tank from being torn.

Corner connectors (3) are welded at four corners of the bottom surface of the buoyancy tank, transverse connecting corner connectors (2) are welded at two sides of the middle of the bottom surface, and sealing strips (4) are further pasted below the edges at two ends of the buoyancy tank body (1). The sealing strip (4) plays the oil-gas sealing effect, prevents that the oil gas in the floating plate clearance from leaking.
