Description

Immersion type floating disc structure without main beam

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 between to along with the floating plate goes up and down to reveal 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 upper and lower edges of the periphery of the buoyancy tank are connected with each other two by two through bolts. These 2 structures have different technical drawbacks: the floating plate structure is provided with a beam frame structure, the main beam and the auxiliary beam bear the load of the floating plate, and the accident of frame disassembly is easy to happen when a large load is applied; in the beamless structure, because 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 generates tearing openings so that oil enters the floating box, thereby generating sinking accidents.

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 beamless structure. The upper plate of the buoyancy tank adopts a buckle plate form, and the periphery of the upper plate is folded upwards; the upper surface of the buoyancy tank side plate is overlapped with the folded edge of the buoyancy tank upper plate to form an edge, and a bolt hole is processed on the edge. The corner connection angle sign indicating number is connected to four angle welding corners below the flotation tank, and the both sides welding transverse connection angle sign indicating number in the middle. The floating boxes are longitudinally connected end to end and are transversely connected in a staggered manner, namely the transverse connecting angle code on the bottom surface of each floating box is connected with the corner connecting angle code of the adjacent floating box. The outlet edge of the upper surface of the buoyancy tank is fixedly connected with the outlet edge of the adjacent buoyancy tank through a bolt, and a sealing strip is also stuck between the outlet edges. The bottom surfaces of the buoyancy tanks are in the longitudinal direction, adjacent corner connecting angle codes are connected with each other, and the transverse direction is that the corner connecting angle codes are connected with the transverse connecting angle codes of the adjacent buoyancy tanks. The upper part and the lower part of the adjacent buoyancy tanks are connected with each other to form the whole floating plate. Corner connection angle sign indicating number and the transverse connection angle sign indicating number of flotation tank have used the reinforcing plate in flotation tank lateral direction to increase the joint strength between the flotation tank. The reinforcing plate has another function of reducing the bending stress of the transverse connection corner brace and preventing the bottom surface of the buoyancy tank from being torn.

the embodiments of the invention are further described below with reference to the accompanying drawings:

fig. 1 is an overall structural view of a buoyancy tank. The periphery of the buoyancy tank body (1) is upward edged. 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 at the edge 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 revealing.

Fig. 2 is a partial assembly view of the float from the top. The figure shows the assembled relationship of several adjacent pontoon bodies (1) from the top. The outlet edges of the adjacent buoyancy tank bodies (1) are close to each other and fixed together by upper connecting screws (5). Sealing strips (4) are stuck at the edge outlet part between the floating boxes. The adjacent buoyancy tank bodies (1) are connected in a staggered manner, namely the longitudinal end-to-end seams of the buoyancy tank bodies (1) are staggered with the longitudinal end-to-end seams of the adjacent buoyancy tank bodies (1).

Fig. 3 is a partial assembly view of the float from the bottom. The figure shows from the bottom how the buoyancy tank bodies (1) adjacent to the bottom of the buoyancy plate are connected together by corner connecting corner connectors (3) and transverse connecting corner connectors (2). The assembly relationship of the supporting legs (7) and the reinforcing plates (6) with the corner connecting corner brace (3) and the transverse connecting corner brace (2) is also shown. Adjacent buoyancy tank bodies (1) in the longitudinal direction are connected together end to end through corner connecting corner connectors (3) and are connected and fixed through lower connecting bolts (8). The side surfaces of the adjacent buoyancy tank bodies (1) are connected with the transverse connecting corner connectors (2) through corner connecting corner connectors (3), and the side surfaces are connected and fixed through lower connecting bolts (8). And a reinforcing plate (6) is arranged between the transverse connecting angle connector (2) and the corner connecting angle connector (3) in the transverse direction of the buoyancy tank body (1). The reinforcing plate (6) is a long plate in the shape of angle steel, two ends of the reinforcing plate are bent, and holes are formed in the bent parts so that the reinforcing plate and the angle steel can be connected and fixed with the transverse connecting angle brace (2) or the corner connecting angle brace (3) through lower connecting bolts (8). The middle of the reinforcing plate (6) is also provided with an installation screw hole, and the supporting leg (7) is fixed on the reinforcing plate (6) through a supporting leg connecting bolt (9). The reinforcing plate (6) is used for enhancing the bending modulus of the transverse connection corner brace (2) and reducing the bending stress of the transverse connection corner brace (2), so that the tearing force caused to the bottom surface of the buoyancy tank body (1) is reduced.
