[0025] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

The corrugated telescopic airbag is connected to an air cylinder through an air duct. The piston in the air cylinder is connected to a push plate through a push rod, and when the push plate is pushed, the piston can be driven to move upward in the air cylinder. In this way, when encountering a wave impact, the wave can push the push plate upward, and the piston on the push rod can squeeze the gas in the air cylinder and make the gas enter the corrugated telescopic airbag through the air duct, so that the corrugated telescopic airbag expands when it extends. The overall volume of the corrugated telescopic airbag increases, making its drainage volume increase, and enhancing the stability of the anti - impact floating box of the offshore photovoltaic support. And when the wave strikes the bottom of the floating plate, the gas in the corrugated telescopic airbag is discharged into the air cylinder through the air duct, causing the piston in the air cylinder together with the push rod to move downward, thereby using the reduction of the volume of the corrugated telescopic airbag itself to reduce the impact of the wave on the floating plate. Multiple anti - impact floating boxes of the offshore photovoltaic support can be connected to form an anti - impact floating platform for the offshore photovoltaic support, which can effectively relieve the impact brought by the wind and waves and improve the anti - impact performance of the overall structure.

[0032] Optionally, a cover plate is arranged at the upper end of the air cylinder, a through - hole is opened on the cover plate, one end of the air duct is connected to the through - hole, and the other end of the air duct is connected to the air inlet of the corrugated telescopic airbag.

[0033] Optionally, an elastic member is arranged between the piston and the cover plate, and the elastic member is used to apply an elastic force to the piston to make it move in a direction away from the cover plate.

[0034] Optionally, the air duct is U - shaped, and the other end of the air duct passes through the floating box body and is connected to the air inlet of the corrugated telescopic airbag.

[0035] Optionally, the corrugated telescopic airbag is cylindrical.

[0036] Optionally, the lower end of the push rod movably penetrates through the floating plate and extends downward.

[0037] Optionally, it further includes a water - deflecting plate. The water - deflecting plate is connected below the floating plate through a connecting frame. The connecting frame is U - shaped. One end of the connecting frame is connected to the floating plate, and the middle parts of both ends of the water - deflecting plate are respectively rotatably connected to the other end of a connecting frame, so that the water - deflecting plate can rotate below the floating plate.

[0038] Optionally, the pushing disk is a conical rubber disk.

[0039] The present invention also provides an impact-resistant floating platform for an offshore photovoltaic support, comprising:

[0040] A plurality of the above-mentioned impact-resistant floating boxes of the offshore photovoltaic support, with a connecting ear provided at each of the four corners of each floating box body. The four connecting ears extend radially outwards, and adjacent two of the above-mentioned impact-resistant floating boxes of the offshore photovoltaic support are connected by two pairs of the connecting ears.

[0041] In one example, a plurality of the above-mentioned impact-resistant floating boxes of the offshore photovoltaic support are arranged in a straight line. Adjacent two of the above-mentioned impact-resistant floating boxes of the offshore photovoltaic support are connected by two pairs of connecting ears and corresponding bolts, so that the above-mentioned impact-resistant floating boxes of the offshore photovoltaic support form an integral impact-resistant floating platform for the offshore photovoltaic support, which can effectively relieve the impact brought by wind and waves and improve the impact resistance of the overall structure.

[0042] Embodiment 1

[0043] As Figure 1 and Figure 2 shown, the present invention provides an impact-resistant floating box for an offshore photovoltaic support, comprising:

[0044] A floating box body 1, with a corrugated telescopic airbag 2 provided below the floating box body 1. The corrugated telescopic airbag 2 can telescopically move in the vertical direction, and a floating plate 3 is provided below the corrugated telescopic airbag 2;

[0045] A plurality of air cylinders 4, connected to the floating box body 1. A piston 5 is movably arranged in the air cylinder 4. The lower end of the piston 5 is connected to a push rod 6, and a pushing disk 7 is provided at the lower end of the push rod 6. The upper end of the air cylinder 4 is connected to an air guide pipe 8, and the air guide pipe 8 is connected to the corrugated telescopic airbag 2.

[0046] Specifically, to solve the problem that the floating boxes of the existing marine photovoltaic brackets have poor impact resistance when facing the impact of wind and waves; the impact-resistant floating box of the marine photovoltaic bracket provided by the present invention is sequentially provided with a corrugated telescopic airbag 2 and a floating plate 3 below the floating box body 1. The corrugated telescopic airbag 2 is connected to an air cylinder 4 through an air duct 8. A piston 5 in the air cylinder 4 is connected to a push plate 7 through a push rod 6. When the push plate 7 is pushed, the piston 5 can be driven to move upward in the air cylinder 4. In this way, when encountering a wave impact, the wave can push the push plate 7 upward, and the piston 5 on the push rod 6 can squeeze the gas in the air cylinder 4 and make the gas enter the corrugated telescopic airbag 2 through the air duct 8, so that the corrugated telescopic airbag 2 extends and expands, and the overall volume of the corrugated telescopic airbag 2 increases, making its drainage volume increase, and enhancing the stability of the impact-resistant floating box of the marine photovoltaic bracket. And when the wave hits the bottom of the floating plate 3, the gas in the corrugated telescopic airbag 2 is discharged into the air cylinder 4 through the air duct 8, so that the piston 5 in the air cylinder 4 together with the push rod 6 moves downward, thereby using the reduction of the volume of the corrugated telescopic airbag 2 itself to reduce the impact of the wave on the floating plate 3. Multiple such impact-resistant floating boxes of the marine photovoltaic bracket can be connected to form an impact-resistant floating platform of the marine photovoltaic bracket, which can effectively relieve the impact of wind and waves on it and improve the impact resistance of the overall structure.

[0047] Optionally, the air cylinder 4 is arranged inside the floating box body 1, and multiple air cylinders 4 are distributed around the floating box body 1.

[0048] Specifically, the air cylinder 4 is in the shape of a vertical cylinder, and the air cylinder 4 is embedded in the position near the outer periphery of the floating box body 1 inside the floating box body 1, and the push rod 6 movably penetrates the bottom plate of the floating box body 1 and extends downward.

[0049] Optionally, a cover plate 9 is arranged at the upper end of the air cylinder 4, a through hole is opened on the cover plate 9, one end of the air duct 8 is connected to the through hole, and the other end of the air duct 8 is connected to the air inlet of the corrugated telescopic airbag 2.

[0050] Specifically, the cover plate 9 seals the upper end of the air cylinder 4, and only the through hole is left to be connected to the air duct 8. When the piston 5 moves upward, it can compress the gas in the air cylinder 4 and make the gas flow upward through the through hole and the air duct 8 to the corrugated telescopic airbag 2.

[0051] Optionally, an elastic member 10 is arranged between the piston 5 and the cover plate 9, and the elastic member 10 is used to apply an elastic force to the piston 5 to move it away from the cover plate 9.

[0052] Specifically, the elastic member 10 can be a spring, which is arranged between the piston 5 and the cover plate 9. As the piston 5 moves upward, the piston 5 can compress the spring to store energy. In this way, after the wave pushes the push plate 7 once, the piston 5 can reset under the action of the spring, restoring the shape of the corrugated telescopic airbag 2 to welcome the next wave's push on the push plate 7.

[0053] Furthermore, if the corrugated telescopic airbag 2 is compressed, the gas enters the air cylinder 4 through the air duct 8. At this time, the piston 5 is pushed downward by the gas, and the spring can also be stretched and store energy.

[0054] Optionally, the air duct 8 is U-shaped, and the other end of the air duct 8 passes through the floating box body 1 and is connected to the air inlet of the corrugated telescopic airbag 2.

[0055] Specifically, the air duct 8 can be made of a stainless steel pipe, bent into a U shape, with one end longer and the other end shorter. The shorter end is connected to the through hole, and the longer end passes downward through the floating box body 1 and is connected to the air inlet of the corrugated telescopic airbag 2.

[0056] Optionally, the corrugated telescopic airbag 2 is cylindrical.

[0057] Specifically, the corrugated telescopic airbag 2 is a cylindrical structure arranged along the circumference of the floating box body 1 and the floating plate 3. After it is connected to the lower surface of the floating box body 1 and the upper surface of the floating plate 3, a hollow cavity structure is formed.

[0058] In this embodiment, the corrugated telescopic airbag 2 is formed by the socket connection of two side walls, namely the inner side wall and the outer side wall. Both the inner side wall and the outer side wall are folded into a wave shape and extend along the vertical direction, forming an airbag structure that can expand and contract vertically during the inflation and deflation process.

[0059] Optionally, the lower end of the push rod 6 movably penetrates through the floating plate 3 and extends downward.

[0060] Specifically, the push rod 6 passes through the bottom plate of the floating box body 1 and through the floating plate 3, guiding the push rod 6 and improving the stability of the push rod 6 during its up and down movement.

[0061] In this embodiment, four air cylinders 4 are provided, and the four air cylinders 4 are respectively located at the four corners of the rectangular floating box body 1.

[0062] Optionally, it further includes a water deflecting plate 11. The water deflecting plate 11 is connected below the floating plate 3 through a connecting frame 12. The connecting frame 12 is U-shaped. One end of the connecting frame 12 is connected to the floating plate 3, and the middle parts of both ends of the water deflecting plate 11 are respectively rotatably connected to the other end of a connecting frame 12, enabling the water deflecting plate 11 to rotate below the floating plate 3.

[0063] Furthermore, two water deflectors 11 are symmetrically arranged below the floating board 3 with respect to the center line of the floating board 3.

[0064] Specifically, when the water surface is fluctuated and the water wave hits the impact-resistant floating box of the offshore photovoltaic support from one side, the water deflector 11 is slapped by the water wave, prompting the water deflector 11 to rotate around the other end of the connecting frame 12, thereby reducing the influence of the impact of the lateral water flow on the floating stability of the impact-resistant floating box of the offshore photovoltaic support.

[0065] Optionally, the pushing disk 7 is a conical rubber disk.

[0066] Embodiment 2

[0067] As Figure 3 shown, the present invention also provides an impact-resistant floating platform for an offshore photovoltaic support, including:

[0068] A plurality of the impact-resistant floating boxes of the offshore photovoltaic support described above. Each of the four corners of the floating box body 1 is respectively provided with a connecting ear 13. The four connecting ears 13 extend radially outward. The impact-resistant floating boxes of two adjacent offshore photovoltaic supports are connected by two pairs of connecting ears 13.

[0069] Specifically, the connecting ear 13 is provided with a connecting hole. Bolts are used to connect the impact-resistant floating boxes of each of the above-mentioned offshore photovoltaic supports to form an impact-resistant floating platform for the offshore photovoltaic support. The addition of the corrugated telescopic airbag 2 and the floating board 3 at the bottom of the impact-resistant floating box of the above-mentioned offshore photovoltaic support greatly enhances the drainage volume of the entire impact-resistant floating platform for the offshore photovoltaic support; when there are waves on the sea surface, the waves push the conical rubber disk, causing the push rod 6 to slide upward along the inner wall of the air cylinder 4, so that the piston 5 can squeeze the gas in the air cylinder 4 and compress the spring, and the gas in the air cylinder 4 is discharged into the corrugated telescopic airbag 2 through the air duct 8, thereby causing the corrugated telescopic airbag 2 to expand, its overall volume increases, its drainage volume increases, and the stability of the impact-resistant floating platform for the offshore photovoltaic support is enhanced; when the wave hits the bottom of the floating board 3, the gas in the corrugated telescopic airbag 2 is discharged into the air cylinder 4 through the air duct 8, causing the push rod 6 therein to slide downward, thereby using the reduction of the volume of the corrugated telescopic airbag 2 itself to reduce the impact of the sea wave on the floating board 3; when the water surface is fluctuated and the water wave hits the impact-resistant floating box of the above-mentioned offshore photovoltaic support from one side, the water deflector 11 is slapped by the water wave, prompting it to rotate around the horizontally extended other end of the connecting frame 12, thereby reducing the influence of the impact of the lateral water flow on the floating stability of the entire impact-resistant floating platform for the offshore photovoltaic support.

[0070] The embodiments of the present invention have been described above. The above description is exemplary and not exhaustive, and is also not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
