[0036] Example 1

[0037] like Figure 1-Figure 7 As shown, the honeycomb pontoon assembly provided in an embodiment of the present invention includes: a plurality of pontoons, the pontoons including a box body 100 and a honeycomb core 200, a receiving cavity for receiving the honeycomb core 200 is arranged inside the box body 100, the outer wall of the honeycomb core 200 is welded to the inner wall of the receiving cavity, and the inner wall of the receiving cavity and the outer wall of the honeycomb core 200 are connected into an integrated structure by welding. A positioning slot 110 is provided on one side of the bottom surface of the box body 100, and a positioning card plate 120 corresponding to the positioning slot 110 is provided on the other side opposite to the bottom surface of the box body 100; a first connecting wing 130 is provided on one side of the top surface of the box body 100, and a second connecting wing 140 is provided on the other side opposite to the top surface of the box body 100, and the first connecting wing 130 is aligned with the positioning slot 110 up and down, and the second connecting wing 140 is aligned with the positioning card plate 120 up and down. When connecting two pontoons, the positioning card plate 120 of one of the pontoons is snapped into the positioning slot 110 of the other pontoon. At this time, the first connecting wing 130 is fitted with the second connecting wing 140, and then the first connecting wing 130 and the second connecting wing 140 are fastened with the bolt assembly 150, thereby completing the snap connection of the two pontoons.

[0038] Specifically, the opening of the positioning slot 110 faces the top surface of the pontoon, and one pontoon moves from top to bottom, and the positioning card plate 120 can be inserted into the positioning slot 110 of another pontoon.

[0039] The positioning slot 110 and the positioning plate 120 can be connected to the bottom surface of the buoyancy tank by welding.

[0040] Specifically, the box body 100 may include a welded box body 310 and a cover body 320, and the cover body 320 is used to buckle and cover the opening of the box body 310 to seal the honeycomb core 200 between the box body 310 and the cover body 320. The cover body 320 is connected to the box body 310 by welding, so that the box body 310 is completely sealed with the cover body 320, ensuring that the honeycomb core 200 is accommodated in the box body 100, reducing the exchange of gas or liquid with the outside, reducing the corrosion rate of the honeycomb core 200, and extending the service life of the buoyancy chamber.

[0041] The box body 310 may be a long rectangular box, and the side walls of the box body 310 relative to the two long sides are provided with a first extension part 311 extending in the direction of the opening, and the cover body 320 is provided with a second extension part 321 perpendicular to the cover body 320 on the two opposite sides, and the cover body 320 is in a U-shaped groove. When the cover body 320 is buckled on the opening of the box body 310, the second extension part 321 is aligned with the inner side wall of the first extension part 311, and one group of the first extension part 311 and the second extension part 321 are welded to form the first connecting wing 130, and the other group of the first extension part 311 and the second extension part 321 are welded to form the second connecting wing 140. The first extension part 311 of the box body 310 and the second connecting part of the cover body 320 are respectively aligned and welded together, which increases the welding area of ​​the two, makes the two less likely to separate, and has a better sealing effect. At the same time, the first connecting wing 130 and the second connecting wing 140 formed by the combination of the first extension part 311 and the second extension part 321 are an integrated structure with the pontoon, and the connection strength of the integrated structure is higher, that is, the connection strength of the first connecting wing 130 and the second connecting wing 140 with the pontoon is better. Compared with the bonding or welding of two independent structures (the first connecting wing 130 and the pontoon, or the second connecting wing 140 and the pontoon), the strength of the integrated structure is higher, so the structural design of the pontoon is more reasonable.

[0042] like Figure 5 As shown, the number of the positioning slots 110 on one side of the bottom surface of the box body 100 can be multiple, and the multiple positioning slots 110 are arranged at intervals on one side of the bottom surface of the buoyancy box. Figure 6 As shown, the number of the positioning slot 110 on one side of the bottom surface of the box body 100 can be one, and the length of the positioning slot 110 is consistent with the length of the box body.

[0043] Example 2

[0044] like Figure 7As shown, it needs to be further explained that the difference from Example 1 is that the top surface of the first extension part 311 is lower than the top surface of the second extension part 321. When the first extension part 311 and the second extension part 321 are attached and welded, a step structure is formed between the first extension part 311 and the second extension part 321. After the first connecting wing 130 and the second connecting wing 140 of the two pontoons are attached, a rectangular glue groove 400 is formed on the top surface of the first connecting wing 130 and the second connecting wing 140. During installation, filling glue can be added to the glue groove 400. The filling glue can be APS low-temperature curing glue. It can be left stationary for a period of time. The filling glue in the glue groove 400 will penetrate into the gap between the first connecting wing 130 and the second connecting wing 140. After the filling glue is cured, the gap is filled, which can prevent the volatilization of fluids such as gasoline, diesel, naphtha and chemicals. The adhesive groove 400 can accommodate a certain amount of filling adhesive. The filling adhesive flows into the gap due to gravity to fill the tiny gap, thereby achieving sealing. The filling adhesive remaining in the adhesive groove 400 solidifies to form a sealing adhesive strip, which plays a further sealing role.

[0045] The honeycomb buoyancy chamber assembly includes a sealing cover 500, which is used to buckle over the fitted first connecting wing 130 and the second connecting wing 140. The sealing cover 500 covers the adhesive groove 400, which can further provide a sealing effect on the one hand, and reduce the corrosion of the filling adhesive from the external environment on the other hand.

[0046] A glue strip 510 corresponding to the glue receiving groove 400 is provided on the bottom surface of the sealing cover 500. The width of the glue strip 510 is twice the thickness of the first extension part 311, and the height of the glue strip 510 is less than the height difference between the top surface of the first extension part 311 and the top surface of the second extension part 321.

[0047] After the first connecting wing 130 and the second connecting wing 140 are attached, the gap between them varies according to the actual situation. In some cases, the gap between them is small. If the filling glue is only relied on the gravity, it is difficult for the filling glue to flow into some narrow gaps. By installing the sealing cover 500, the glue strip 510 on the bottom surface of the sealing cover 500 will enter the glue receiving groove 400. As the sealing cover 500 descends, the glue strip 510 will gradually squeeze the uncured filling glue and squeeze the filling glue to the middle position between the first connecting part and the second connecting part.

[0048] The width of the glue strip 510 is set to be twice the thickness of the first extension portion 311 in order to reduce the filling glue from being squeezed out from the top. The height of the glue strip 510 is set to be less than the height difference between the top surface of the first extension portion 311 and the top surface of the second extension portion 321 in order to ensure that after the glue strip 510 completely enters the glue receiving groove 400, there is also a certain gap between the bottom surface of the glue strip 510 and the bottom surface of the glue receiving groove 400 for accommodating the filling glue.

[0049] The glue strip 510 is elastic and can be made of rubber.

[0050] The opposite sides of the glue strip 510 respectively include a plurality of first pressing sheets and a second pressing sheet arranged along the height direction of the glue strip 510, the plurality of first pressing sheets are arranged at intervals, the plurality of second pressing sheets are arranged at intervals, and the first pressing sheets and the second pressing sheets are aligned. There are gaps between the plurality of first pressing sheets and the plurality of second pressing sheets. When the sealing cover 500 is buckled on the first connecting wing 130 and the second connecting wing 140, part of the filling glue is squeezed downward, and part of the filling glue overcomes the deformation of the pressing sheets and enters the gaps between the pressing sheets. The gaps between the pressing sheets are used to accommodate the filling glue overflowing outward, further preventing the filling glue from overflowing into the sealing cover 500 due to excessive filling glue, so that the installation of the sealing cover 500 is more convenient.

[0051] Example 3

[0052] like Figure 8 As shown, it is necessary to further explain that the difference from the first and second embodiments is that, on the pontoon, a first folding plate 610 is provided on the side of the positioning card plate 120 facing the positioning card slot 110, the first folding plate 610 is perpendicular to the positioning card plate 120, and a second folding plate 620 perpendicular to the first folding plate 610 is provided at the outer end of the first folding plate 610, the first folding plate 610 and the second folding plate 620 are in an inverted L shape, and there is a gap between the second folding plate 620 and the positioning card plate 120, and the gap is used to accommodate the groove wall of the positioning card slot 110 facing away from the positioning card plate 120. The positioning card slot 110 clamps the positioning card plate 120, and the positioning card plate 120 and the second folding plate 620 clamp the outer groove wall of the positioning card slot. Through the multi-bending clamping mode, the connection between the two adjacent pontoons is more stable, which is helpful for pre-fixation during installation and prevents another unfixed pontoon from tilting, and then the first connecting wing 130 and the second connecting wing 140 are fastened with the bolt assembly 150. At the same time, the gap length between the bottoms of two adjacent pontoons is increased, and there are multiple bends, and the gap formed by the second folding plate 620 and the positioning slot 110 opens downward, reducing the oil from entering and accumulating in the gap between the two adjacent pontoons.

[0053] The floating plate system provided in the embodiment of the present invention comprises a sealing device and the above-mentioned honeycomb pontoon assembly, wherein the sealing device is arranged around the circumferential outer side of the honeycomb pontoon assembly. Since the honeycomb pontoon assembly has the above-mentioned beneficial effects, the floating plate system provided in the embodiment of the present invention also has the above-mentioned beneficial effects.

[0054] Finally, it should be noted that the above embodiments are only specific implementations of the present invention, which are used to illustrate the technical solutions of the present invention, rather than to limit them.
