Two adjacent L-shaped assemblies 4 are spliced in such a way that the c (side) surface connects to the g (side) surface, and the d (side) surface connects to the f (side) surface. The e (side) face of the L-shaped combination 4 in the splicing body joins the g (side) of the L-shaped combination 4 in one of the adjacent rows, and the h ( Side) face joins with the f (side) face of the L-shaped assembly 4 in another adjacent row that it splices, any square pontoon 3 at the center of the splicing body all joins with six adjacent square pontoons. The size of square floating tank 3 is preferably that the length of the long side is 2 times of the length of the short side.

At the same time, the buoyancy unit can be separately Replacement, when a buoyancy unit in the floating plate is damaged, there is no need to replace the entire floating plate, the structural strength of the floating plate is strong, and the connecting part of the square floating tank is in the middle of the long side of the adjacent square floating tank, avoiding connection The stress concentration caused by seams on the same straight line, meanwhile, the long sides of the adjacent square pontoons can play the role of anti-bending. Of course, other splicing methods in the prior art may also be used in the buoyant box splicing method, which will not be repeated here.

A kind of preferred scheme, due to the restriction of tank body manhole size, there is size requirement to square pontoon 3, in order to make square pontoon 3 can pass through in the tank body manhole, the design of square pontoon is generally smaller, but This will undoubtedly increase the splicing difficulty of the square floating tank 3, and the number of splicing seams will increase accordingly, and the connection strength of the entire disk body will decrease. The square pontoon comprises at least two square pontoon monomers 3-1 spliced side by side. Specifically in this embodiment, the number of square floating tank monomers 3-1 is three. The size of the square pontoon unit 3-1 is designed to pass through the manhole of the tank body. Three square pontoon units 3-1 are spliced side by side to form a square pontoon 3, and then the entire panel is spliced. The square pontoon unit 3 -1 At the splicing place, the single connector with the same structure as the profile connector is used for sealed connection, which not only reduces the number of splicing seams between the square pontoon tanks, but also makes the splicing between the square pontoon tank monomers 3-1 easier Operation, on-site assembly efficiency is improved. The rest of the structure of this embodiment is the same as that of this embodiment, and will not be repeated here.

Example 3

Referring to Fig. 3-Fig. 7, the difference from embodiment 2 is that each square floating tank monomer 3-1 is composed of honeycomb sub-board 3-1-1 and the two sides of honeycomb sub-board 3-1-1. The sub-plate 3-1-2 is composed of two sub-panels 3-1-2 and the honeycomb sub-panel 3-1-1 through welding (brazing) to realize the sealing of the honeycomb holes in the honeycomb sub-panel 3-1-1 . The honeycomb panels in the square pontoon are spliced sequentially by three honeycomb sub-boards 3-1-1 in the three square pontoon units, and the cover plates on both sides of the square pontoon are composed of three square pontoon units. The three sub-boards on the corresponding side of the body are spliced in sequence. The honeycomb holes in the honeycomb sub-board 3-1-1 are arranged on the sub-board 3-1-2. The materials of the sub-board 3-1-2 and the honeycomb sub-board 3-1-1 are all made of aluminum. Two adjacent square pontoon monomers 3-1 are connected by a single profile connector with the same structure as the profile connector at the joint. The structure of the single profile connector is similar to that of the profile connector, and will not repeat. The rest of the structure of this embodiment is the same as that of Embodiment 1. In this implementation, when the size of the square pontoon unit is designed to be smaller than the tank wall manhole, all accessories can directly pass through the tank wall manhole. The splicing can not only reduce the splicing time, but also improve the connection strength of the entire floating plate. The square floating tank is sealed and welded, which improves the oil resistance and avoids the problem of cracking and failure of the adhesive.

An annular mounting groove is formed between the pressure plate 14 and the ring plate 1. The outer edge of the disc structure 2 is clamped in the annular mounting groove and connected and fixed by the ring plate bolt assembly 15. Between the disc structure 2 and the annular mounting groove An oil-resistant sealing gasket 16 is provided between the ring plate bolt assembly 15 and the ring plate connecting plate 13 . In this embodiment, the ring plate 1 and the disc structure 2 are connected by bolts, which is convenient for disassembly and assembly. An oil-resistant sealing gasket is provided between the ring plate bolt assembly 15 and the ring plate connecting plate 13 to further improve the sealing performance of the entire disc body.

Example 5

Referring to Fig. 8, the difference from Embodiment 4 is that the inner floating plate in this embodiment also includes an edge arranged on the outside of the ring plate 1 to cooperate with the inner wall of the oil tank to realize the sliding seal between the ring plate 1 and the inner wall 17 of the oil tank Sealed structure. Specifically, the edge sealing structure is composed of two upper and lower sealing layers, the upper part of the two sealing layers is sealed and connected with the top outer edge of the ring plate 1 through the mounting plate 18, and the two sealing layers are separated from each other at the lower part; wherein, the upper sealing layer 19 The lower part of the lower sealing layer 20 is attached to the inner wall 17 of the oil tank and immersed in the oil body, the lower part of the lower sealing layer 20 is attached to the outer wall of the ring plate 1, and the upper sealing layer 19 is composed of a spring steel plate, a sealing film and a membrane support plate (with elasticity) from top to bottom. ), the lower sealing layer 20 is an elastic sealing bead layer. The edge sealing structure of this embodiment has a compensation function, and a completely airtight space is formed between the upper and lower sealing layers and the liquid surface, especially in the case of positive pressure generated by volatilization of oil and gas, the upper sealing layer will be close to the tank wall , to prevent oil and gas from leaking between the upper sealing layer and the tank wall, and the positive pressure generated by the volatilization of oil and gas will make the lower sealing layer close to the outer wall of the ring plate, preventing oil and gas from entering the joint between the lower sealing layer and the outer wall of the ring plate through the ring plate Give way. The completely sealed space can generate buoyancy, thereby improving the problem of insufficient buoyancy around the space. Compared with the existing primary and secondary sealing structure, this sealing structure has a large compensation, the compensation amount reaches 400mm, and its service life is far longer than that of ordinary primary and secondary seals. Of course, the edge sealing structure can also adopt other sealing structures in the prior art that have a sliding sealing function and are suitable for sealing the edge of the floating plate.

When a fire breaks out in the floating roof oil tank, the fire extinguishing system 21 can directly send the fire extinguishing agent between the bottom of the floating plate and the oil surface to realize rapid fire extinguishing. The fire extinguishing system 21 can adopt any device suitable for oil tank fire extinguishing in the prior art, and its specific structure is all in the prior art, and will not be repeated here.

Table 1 shows the performance comparison between the floating disc in this embodiment and the traditional adhesive honeycomb panel floating disc. It can be seen from Table 1 that the overall performance of the inner floating plate, such as weight, bending strength, service life, and high and low temperature adaptability, is significantly improved compared with the inner floating plate of the adhesive honeycomb panel.
