[0040] like Figures 1 to 3 As shown, the present invention discloses a modular pontoon platform for water operations, including a pontoon module 1 and a connecting assembly 2, the pontoon module 1 is provided with a plurality of connecting grooves 3 along its four side walls, the connecting grooves 3 extending from the top to the bottom of the pontoon module 1; the connecting assembly 2 can be inserted into two connecting grooves 3 facing each other in the vertical direction to fasten two adjacent pontoon modules 1; the connecting assembly 2 includes a first locking member 4 and a second locking member 5, the first locking member 4 is located at the bottom of the second locking member 5, the first locking member 4 is an "I"-shaped structure, the second locking member 5 includes a connecting block, a propping assembly and a clamping assembly, a accommodating cavity is provided in the connecting block, the propping assembly is arranged in the accommodating cavity along the vertical direction, the clamping assembly is arranged in the accommodating cavity along the horizontal direction, and the propping assembly is located at the top of the clamping assembly so that when the propping assembly moves downward, it is convenient to push the clamping assembly to move outward and clamp with the groove of the side wall of the pontoon module 1.

[0041] The connecting groove 3 includes a first connecting groove and a second connecting groove. The first connecting groove is located at the top of the second connecting groove. The first connecting groove is a square structure with an outer opening. The height of the first connecting groove is consistent with the height of the connecting block. The width of the first connecting groove is consistent with the width of the connecting block. The length of the first connecting groove is less than half of the length of the connecting block. An opening is provided in the middle of the outer side of the second connecting groove to facilitate the insertion of the first locking piece 4.

[0042] The number of pontoon modules 1 required is determined according to the size of the pontoon platform, and multiple pontoon modules 1 are brought close to each other, and every two adjacent pontoon modules 1 are tightly attached to each other. The second connecting grooves of the connecting grooves 3 on the side walls of the two pontoon modules 1 form an "I"-shaped connecting groove, and the first locking piece 4 is inserted downward into the two second connecting grooves facing each other. The length of the first locking piece 4 is consistent with the length of the second connecting groove, the bottom of the second locking piece 5 contacts the top of the second connecting groove, and the second locking piece 5 is located in the two first locking pieces facing each other. The expansion component moves downward along the height direction of the accommodating cavity to push the clamping component to move to both sides so that the clamping component is clamped with the groove on the inner wall of the pontoon module 1, so that the position of the first locking piece 4 is fixed and the position of the adjacent pontoon modules 1 is fixed; the expansion component moves upward along the height direction of the accommodating cavity, and the clamping component releases the clamping with the groove on the inner wall of the pontoon module 1, so that the connecting component 2 is disengaged from the connecting groove 3, and the connection between the adjacent pontoon modules 1 is released; the rapid assembly and disassembly of multiple pontoon modules 1 are realized through the connecting component 2.

[0043] The accommodating cavity includes a screw hole 6, a first cavity 7 and a second cavity 8. The screw hole 6 is arranged in the vertical direction and is located at the top of the first cavity 7 and is connected to the first cavity 7. The first cavity 7 is located at the top of the second cavity 8 and is connected to the second cavity 8. The first cavity 7 is perpendicular to the second cavity 8 along the length direction. The first cavity 7 and the second cavity 8 both pass through the connecting block horizontally.

[0044] In this embodiment, the connecting block is a square block, and the screw hole 6 is arranged along the height direction of the connecting block. The screw hole 6 extends downward from the top of the connecting block to the first cavity 7. The first cavity 7 is horizontally arranged along the width direction of the connecting block. The length of the first cavity 7 is consistent with the width of the connecting block, the width of the first cavity 7 is smaller than the length of the connecting block, and the width of the first cavity 7 is consistent with the maximum width of the expansion assembly. The length of the second cavity 8 is consistent with the length of the connecting block, the width of the second cavity 8 is smaller than the width of the connecting block, and the width of the second cavity 8 is consistent with the width of the snap-in assembly, which facilitates the movement of the snap-in assembly along the length direction of the second cavity 8.

[0045] The first locking member 4 includes a first I-beam 9, a second I-beam 10 and a third I-beam 11. Both ends of the third I-beam 11 along the width direction are respectively fastened to the middle parts of the first I-beam 9 and the second I-beam 10 along the width direction to form an "I"-shaped structure.

[0046] In this embodiment, the first I-beam 9 and the second I-beam 10 are the two horizontal ends of the "I"-shaped structure, and the third I-beam 11 is the vertical end of the "I"-shaped structure. The first I-beam 9 and the second I-beam 10 are respectively inserted into the opposing connecting grooves 3, and the third I-beam 11 passes through the outer openings of the opposing connecting grooves 3 to keep the positions of the two connecting grooves 3 fixed, even if the positions of the two adjacent pontoon modules 1 remain fixed.

[0047] The support assembly includes a bolt 12 and a top block 13, the external thread of the bolt 12 matches the internal thread of the screw hole 6, the bolt 12 is provided with a snap-in groove 24 near the bottom, the snap-in groove 24 is circumferentially arranged around the bolt 12, the bolt 12 passes through the screw hole 6 and reaches the first cavity 7, the bottom of the top block 13 is wedge-shaped for supporting the snap-in assembly, a snap-in interface 14 is provided at the top center of the top block 13, the width of the snap-in groove 14 matches the snap-in groove 24 to facilitate the snap-in groove 24 to be inserted into the snap-in interface 14, a third cavity 15 is provided on the lower side of the card interface 14, the size of the third cavity 15 matches the size of the bottom of the bolt 12 to facilitate the top block 13 to slide into the first cavity 7 so that the bottom of the bolt 12 is embedded in the third cavity 15.

[0048] In this embodiment, the top block 13 is a square block with a wedge-shaped bottom. The width of the top block 13 is consistent with the width of the first cavity 7, and the height of the top block 13 is consistent with the height of the first cavity 7, preventing the top block 13 from moving left and right within the first cavity 7. After the bolt 12 is screwed into the screw hole 6, the clamping groove 24 moves downward along the height direction of the screw hole 6. After the clamping groove 24 moves into the first cavity 7, the top block 13 is inserted into the first cavity 7 along the side wall of the connecting block. The clamping interface 14 at the top of the top block 13 is clamped with the clamping groove 24. The part of the bolt 12 located below the clamping groove 24 is located within the third cavity 15. Continuing to screw the bolt 12 downward, the bolt 12 pushes the top block 13 downward. If one side of the top block 13 is a wedge-shaped structure, when the top block 13 moves from the first cavity 7 to the second cavity 8 along the height direction, it pushes the clamping component to move to one side. If the bolt 12 is continuously screwed into the screw hole 6, the top block 13 pushes the clamping component to continuously move towards the floating box module 1 until the clamping component is tightly clamped with the groove on the side wall of the floating box module 1, fixing the position of the first locking member 4 and, at the same time, fixing the positions of two adjacent floating box modules 1. If both sides of the top block 13 are wedge-shaped structures, when the top block 13 moves from the first cavity 7 to the second cavity 8 along the height direction, it pushes the clamping component to move horizontally towards both sides. If the bolt 12 is continuously screwed into the screw hole 6, the top block 13 pushes the clamping component to continuously move towards the floating box modules 1 on both sides until the clamping component is tightly clamped with the grooves on the side walls of the floating box modules 1 on both sides, fixing the position of the first locking member 4 and, at the same time, fixing the positions of two adjacent floating box modules 1. It can be seen that the fixing effect of the first locking member 4 with both sides of the top block 13 being wedge-shaped structures is better than that with one side of the top block 13 being a wedge-shaped structure, making the connection between two adjacent floating box modules 1 more stable. Since the clamping interface 14 of the top block 13 is clamped with the clamping groove 24, the relative position of the top block 13 and the bolt 12 is fixed, preventing the top block 13 from detaching from the bolt 12.

[0049] Both the left and right sides of the bottom of the top block 13 are provided with first inclined surfaces 22.

[0050] In another possible embodiment, different from the above embodiment, both sides of the bottom of the top block 13 are provided with first inclined surfaces 22. The first inclined surfaces 22 make the bottom width of the top block 13 smaller, facilitating the width of the top block 13 to gradually increase during the downward movement, and facilitating the first clamping member 16 and the second clamping member 17 to move away from each other.

[0051] The clamping component includes a first clamping member 16, a second clamping member 17, and a return spring 18. The first clamping member 16 and the second clamping member 17 have the same structure and are spaced apart in the second cavity 8. The top of the side where the first clamping member 16 and the second clamping member 17 are close to each other is wedge-shaped to facilitate the expansion component to push the first clamping member 16 and the second clamping member 17 away from each other in the horizontal direction. The return spring 18 is installed between the first clamping member 16 and the second clamping member 17 and is fixedly connected to the first clamping member 16 and the second clamping member 17 respectively. At the position near the top of the side where the first clamping member 16 and the second clamping member 17 are away from each other, there are convex blocks 21 to facilitate being inserted into the grooves of the floating box module 1.

[0052] In this embodiment, the first clamping member 16 and the second clamping member 17 are spaced apart along the length direction of the second cavity 8. The initial distance between the tops of the first clamping member 16 and the second clamping member 17 is consistent with the width of the bottom of the top block 13, which is convenient for the top block 13 to push the first clamping member 16 and the second clamping member 17 away from each other when moving downward. The bolt 12 pushes the top block 13 downward. The wedge-shaped structure at the bottom of the top block 13 cooperates with the wedge-shaped structures at the tops of the first clamping member 16 and the second clamping member 17 to push the first clamping member 16 and the second clamping member 17 away from each other. The return spring 18 is stretched under the action of the first clamping member 16 and the second clamping member 17. The bolt 12 pushes the top block 13 to move downward continuously, and the first clamping member 16 and the second clamping member 17 move away from each other continuously until the convex blocks 21 are inserted into the grooves on the side wall of the floating box module 1, and the connecting components 2 are inserted into all the connecting grooves 3 on the adjacent side walls of the two adjacent floating box modules 1 to tightly connect the adjacent floating box modules 1.

[0053] The first clamping member 16 includes a clamping block 19 and a connecting rod 20. The clamping block 19 is wedge-shaped. The connecting rod 20 passes through the clamping block 19 in the horizontal direction. The outer side of the connecting rod 20 is fixedly connected to the clamping block 19 by a nut. The inner side of the connecting rod 20 is connected to the return spring 18. The convex block 21 is located on the upper side of the connecting rod 20.

[0054] In this embodiment, the wedge shape at the top of the clamping block 19 matches the wedge shape at the bottom of the top block 13. The top block 13 moves downward to push the two clamping blocks 19 away from each other. Since the outer side of the connecting rod 20 is fixedly connected to the clamping block 19 by a nut, the position of the connecting rod 20 is fixed, and the connecting rod 20 drives the return spring 18 to be stretched continuously; if the top block 13 moves upward, the two clamping blocks 19 approach each other under the elastic force of the return spring 18, so that the distance between the two clamping blocks 19 reaches the initial distance.

[0055] On the side where the tops of the first clamping member 16 and the second clamping member 17 are close to each other, there are second inclined surfaces 23.

[0056] In this embodiment, the inclination angle of the second inclined surface 23 is consistent with that of the first inclined surface 22, facilitating the downward movement of the top block 13 along the second inclined surface 23 to push the first engaging member 16 and the second engaging member 17 away from each other. If the top block 13 moves upward along the second inclined surface 23, then under the action of the return spring 18, the first engaging member 16 and the second engaging member 17 approach each other.

[0057] Pulling rings are provided at both ends of the top block 13 along its length direction.

[0058] In this embodiment, providing pulling rings at both ends of the top block 13 facilitates pulling the top block 13 out of the first cavity 7 when disassembling the floating box module 1, improving the disassembly efficiency.

[0059] During use, determine the number of floating box modules 1 required according to the size of the floating box platform. Move multiple floating box modules 1 closer to each other. Insert the connecting assembly 2 downward into the opposing connecting grooves 3. The first locking member 4 fixes the positions of adjacent floating box modules 1. The second locking member 5 is located between two floating box modules 1. Screw the bolt 12 downward into the screw hole 6. When the engaging groove 24 at the bottom of the bolt 12 reaches the first cavity 7, push the top block 13 into the first cavity 7 so that the engaging port 14 at the top of the top block 13 is in close contact with the inner wall of the engaging groove 24. The bottom of the bolt 12 is embedded in the third cavity 15 of the top block 13. Continue to screw the bolt 12 downward. The bolt 12 pushes the top block 13 downward. The top block 13 moves between the opposing first engaging member 16 and second engaging member 17 and pushes the first engaging member 16 and the second engaging member 17 away from each other. Under the action of the first engaging member 16 and the second engaging member 17, the return spring 18 is in a stretched state until the convex block 21 is engaged into the floating box module 1, then stop screwing the bolt 12 downward. At this time, the position of the first locking member 4 in the connecting groove 3 is fixed, and the first locking member 4 successfully fixes the positions of adjacent two floating box modules 1. If it is necessary to disassemble the assembled floating box module 1, unscrew the bolt 12 upward. The bolt 12 drives the top block 13 to move upward. Under the action of the return spring 18, the first engaging member 16 and the second engaging member 17 approach each other until the bottom of the top block 13 reaches the first cavity 7 and the distance between the first engaging member 16 and the second engaging member 17 returns to the initial spacing, then the convex block 21 disengages from the groove of the floating box module 1. Take out the connecting assembly 2 upward to release the connection of the connecting assembly 2 to the floating box module 1, improving the disassembly and assembly efficiency of the floating box module 1 through the connecting assembly 2.

[0060] A construction method for a modular floating box platform for water operations includes the following steps:

[0061] Step 1: Horizontally bring two floating box modules closer and align them. Insert the two horizontal ends of the first locking member below the connecting assembly into the connecting grooves of the two floating box modules respectively by means of a crane.

[0062] Step 2: Screw the bolt into the screw hole, push the top block into the first cavity along the length direction of the first cavity, and the clamping opening at the top of the top block is in clamping fit with the groove of the bolt;

[0063] Step 3: Continuously screw the bolt into the screw hole, and at the same time push the top block to push the first clamping part and the second clamping part away from each other;

[0064] Step 4: The convex blocks on the outer sides of the first clamping part and the second clamping part are clamped into the side wall of the floating box module, and then the two floating box modules are locked horizontally;

[0065] Step 5: Repeat the above steps to assemble two module groups respectively formed by horizontally connecting two floating box modules;

[0066] Step 6: Vertically bring the two assembled module groups closer and align them, and use the methods of Step 1 to Step 4 to assemble a floating box group composed of four floating box modules; when disassembling the floating box group, first perform vertical disassembly and then horizontal disassembly.

[0067] The above are only the preferred embodiments of the present invention, and do not impose any limitations on the present invention. Any simple modifications, changes, and equivalent structural transformations made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
