Description

Technical Field

[0001] The invention relates to the technical field of offshore floating bodies, in particular to an offshore floating body structure based on glass fiber composite materials. Background Art

[0002] An offshore floating structure refers to a platform that can be built on the water surface through simple operations, so that a series of operations and work can be carried out more conveniently on the water surface, which brings great convenience to the work on the water surface, and through the splicing of the offshore floating structure, it can often be applied to different occasions on the water surface. Existing offshore floating structures are all spliced ​​together by many floats and then suspended on the water surface through buoyancy, so that people can move on it, but when used on the sea surface, there will be many small waves on the sea surface due to the strong sea breeze on the sea surface, which is the frequent ups and downs of the water surface. This often makes it difficult to complete the splicing of the offshore floating structure in a short time, and the use of conventional threaded connections often leads to severe aging after long-term use on the sea surface, making it difficult to disassemble.

[0003] To solve the above problems, China's patent publication number CN114148445B discloses an offshore floating structure made of composite materials. The floating structure is modularly assembled, and a single floating body is composed of three layers of polymer resin materials with different components, namely a smooth outer surface layer, an extrusion deformation layer, and a foaming layer. The three layers are bonded together by hot pressing. The modular floating structures are also connected together by locking devices, which makes it easy to splice the floating structures on the water surface into different areas for human activities, and also greatly improves the splicing performance, anti-oxidation performance and structural strength of the floating structure.

[0004] The device can connect adjacent floating structures through a locking device, and the connection is simple. The conical rod needs to be pushed into the inside of the expandable and closable fixing part to open the expandable and closable fixing part to achieve the connection of the adjacent floating structures. However, in actual use, due to the undulating sea surface, the expandable and closable fixing part will move in the direction of the sea surface fluctuations, and there is a risk of falling out. In addition, the floating structures of the application are all made of plastic, and their support effect is poor and they are prone to rupture.

[0005] Therefore, the present application provides an offshore floating structure based on glass fiber composite materials to solve the problems of weak connection and poor supporting effect of offshore floating structures in the prior art, thereby ensuring the service life of the offshore floating structure.

[0027] like Figure 2-9 As shown, an offshore floating structure based on glass fiber composite materials includes a plurality of spliced ​​floating blocks 1, wherein the floating blocks 1 include, from top to bottom, an upper surface layer 2, an extrusion deformation layer 3, a glass fiber composite material skeleton 4 and a foaming layer 5, a first connecting block 6 is connected to one side of the upper part of the floating block 1, and a second connecting block 7 is connected to the other side of the upper part of the floating block 1, the first connecting block 6 and the second connecting block 7 of adjacent floating blocks 1 are detachably connected, and the first connecting block 6 and the second connecting block 7 are rotated 90° after being connected to lock the adjacent floating blocks 1.

[0028] Two adjacent floating blocks 1 are connected by a first connecting block 6 and a second connecting block 7 , so the first connecting block 6 and the second connecting block 7 should be symmetrically arranged on the edge of the floating block 1 so that the edges of adjacent floating blocks 1 can be connected by the first connecting block 6 and the second connecting block 7 .

[0029] The thickness of the upper surface layer 2 is 3-5 mm, the thickness of the extrusion deformation layer 3 is 5-10 mm, the thickness of the foaming layer 5 is not less than half of the sum of the thicknesses of the upper surface layer 2 and the extrusion deformation layer 3, the thickness of the glass fiber composite material skeleton 4 is greater than the sum of the thicknesses of the upper surface layer 2 and the extrusion deformation layer 3, and a plurality of chambers are arranged inside the glass fiber composite material skeleton 4.

[0030] like Figure 3 and Figure 5As shown, the upper part of the floating block 1 is provided with a first connecting groove and a second connecting groove, the first connecting block 6 is slidably disposed in the first connecting groove, and the second connecting block 7 is rotatably disposed in the second connecting groove; A semicircular guide rail 8 is disposed inside the first connecting groove and the second connecting groove, and a semicircular guide block is disposed at the bottom of the first connecting block 6 and the second connecting block 7 , and the guide block is slidably connected to the guide rail 8 .

[0031] The first connecting groove and the second connecting groove have the same structure, the guide rail 8 inside the first connecting groove and the guide rail 8 inside the second connecting groove are arranged opposite to each other, the outer ends of the two oppositely arranged guide rails 8 are both open, and the guide block can slide between the two oppositely arranged guide rails 8.

The first connecting block 6, the first connecting plate 10, the second connecting plate 12 and the second connecting block 7 are spliced ​​into a circle.

[0033] The first connecting plate 10 and the second connecting plate 12 are arranged vertically and in parallel, and the lengths of the first connecting plate 10 and the second connecting plate 12 are not greater than the diameters of the first connecting block 6 and the second connecting block 7.

[0034] like Figure 3 and Figure 4 As shown, the first connecting plate 10 and the second connecting plate 12 have the same structure, and the edge of one side of the first connecting plate 10 away from the first connecting block 6 is gathered to form a guide slope, and the side surface of the first connecting plate 10 and the four connected guide slopes are provided with connecting magnets 13, and the connecting magnets 13 of the first connecting plate 10 and the connecting magnets 13 of the second connecting plate 12 have opposite magnetic poles on opposite sides.

[0035] The connecting magnet 13 can be a whole piece or multiple magnets evenly distributed. The guide slope is also provided with a connecting magnet 13. When the first connecting plate 10 and the second connecting plate 12 are angularly offset, they can be connected through the connecting magnet 13 on the guide slope to prevent the two from being separated.

[0036] like Figure 3 and Figure 4 As shown, a positioning rod 14 is provided in the middle of one side of the first connecting plate 10 away from the first connecting block 6, and a positioning hole 15 is provided in the middle of the second connecting block 7 and the middle of the second connecting plate 12.

The length of the positioning hole 15 is greater than the diameter of the positioning rod 14, and an arc-shaped limiting plate 16 is movably provided on the upper part of the positioning hole 15.

[0037] When the limiting plate 16 is pushed in the direction of the positioning rod 14 , the positioning hole 15 and the positioning rod 14 can be pressed tightly to lock the two, thereby preventing the two from being displaced.

[0038] like Figure 3 and Figure 4 As shown, a positioning push rod 17 is provided on the upper side of the positioning hole 15 , and the positioning push rod 17 is connected to the limiting plate 16 .

[0039] like Figure 5 As shown, a driving groove is opened on the upper part of the floating block 1, and a driving motor is rotatably arranged inside the driving groove. The output shaft of the driving motor is connected to a driving roller 18, and the driving roller 18 is arranged in contact with the circumferential surface of the first connecting block 6 or the circumferential surface of the second connecting block 7.

[0040] The driving roller 18 may also be a driving gear. When the driving motor is connected to the driving gear, the outside of the first connecting block 6 and the outside of the second connecting block 7 should be provided with connecting gear rings, and the driving gear is meshed and connected with the connecting gear rings.

[0041] like Figure 2 As shown, the upper surface layer 2 is a polyethylene resin layer, the extrusion deformation layer 3 is a polyamide resin layer, the foaming layer 5 is formed by foaming and melting the prepared foaming particles containing resin, the glass fiber composite material skeleton 4 is a glass fiber reinforced polyurethane material, and the glass fiber composite material skeleton 4 includes two support plates arranged in parallel and a support vertical plate connected between the two support plates.

[0042] Directions: When the device is used, the buoy 1 is directly placed on the sea surface, and the first connecting block 6 of the buoy 1 is arranged opposite to the second connecting block 7 of the adjacent buoy 1; The first telescopic rod 9 and the second telescopic rod 11 are extended to make the first connecting plate 10 and the second connecting plate 12 extend outward, and the first connecting plate 10 and the second connecting plate 12 are arranged opposite to each other; Insert the positioning rod 14 on the first connecting plate 10 into the positioning hole 15. Since the length of the positioning hole 15 is greater than the diameter of the positioning rod 14, the difficulty of connecting the positioning rod 14 and the positioning hole 15 can be greatly reduced. After the positioning hole 15 is connected to the positioning rod 14, the first connecting plate 10 and the second connecting plate 12 are magnetically attracted to each other, the positioning push rod 17 is extended, and the positioning rod 14 is pressed by the limiting plate 16. Figure 5 a first installation state shown; The first telescopic rod 9 and the second telescopic rod 11 are shortened, so that the first connecting plate 10 is in close contact with the first connecting block 6, the first connecting plate 10 is received in the first connecting groove, and the second connecting plate 12 is received in the second connecting groove, so that the two adjacent floating blocks 1 are tightly connected. Figure 7 The second installation state shown; The driving motor is driven to rotate the first connecting block 6 and the second connecting block 7 through the driving roller 18, so that the length direction of the first connecting block 6 and the second connecting block 7 is perpendicular to the edge of the floating block 1, and the first connecting block 6 and the second connecting block 7 are used to lock the two adjacent floating blocks 1. Figure 8 The third installation state shown; In order to improve the connection tightness between the first connection block 6, the second connection block 7 and the floating block 1, on the basis of the above-mentioned locking state, the first connection block 6 and the floating block 1, and the second connection block 7 and the floating block 1 can also be reinforced by connecting bolts or the like.

[0043] Since the diameter of the positioning hole 15 is much larger than the diameter of the positioning rod 14, the difficulty of connecting the two can be greatly reduced, and guide slopes are set on the edges of the first connecting plate 10 and the second connecting plate 12, allowing the two to produce relative displacement or even bending during the docking process, and the two can be flexibly limited by the connecting magnet 13.

[0044] The positioning rod 14 and the positioning hole 15 are used for preliminary docking to achieve efficient docking of the first connecting plate 10 and the second connecting plate 12, so that the first connecting block 6 and the second connecting block 7 can be docked and matched, and then the first connecting block 6 and the second connecting block 7 are rotated to lock the two connected floating blocks 1, thereby effectively improving the installation efficiency between the floating blocks 1 and the stability of the offshore floating structure.
