[0037] The invention discloses a damping pool type offshore floating photovoltaic platform to realize the rapid lifting and lowering of the floating platform.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0040] like Figures 1 to 8 As shown, the present invention discloses a damping pool type offshore floating photovoltaic platform, including a floating platform 2, a photovoltaic module 1 and a cabin 7. The floating platform 2 floats on the sea surface and is fixed by a mooring rope 6. The floating platform 2 can be a rectangular platform, and its size can be set according to different needs. The above-mentioned photovoltaic module 1 is used to convert solar energy into electrical energy. In order to ensure the function of the photovoltaic module 1, the photovoltaic module 1 is installed above the floating platform 2, that is, located above the sea surface, to prevent the corrosion of the photovoltaic module 1 by seawater.

[0041] A cabin 7 is provided on the floating platform 2, and an airbag 9 capable of adjusting buoyancy is provided in the cabin 7. The buoyancy of the floating platform can be changed by inflating and deflating the airbag 9. It should be noted that the airbag 9 in this article is a flexible airbag with variable volume. Under extreme sea conditions, the air in the airbag 9 can be increased to increase the buoyancy of the floating platform 2, reduce the draft of the floating platform 2, increase the freeboard of the floating platform 2, improve the anti-sinking and large-angle stability of the floating platform 2, enhance the survivability of the floating platform 2 under extreme sea conditions, and avoid the problem of waves hitting the photovoltaic panel 1 under extreme sea conditions.

[0042] By providing the airbag 9 and adjusting the inflation and deflation of the airbag 9 to adjust the rise and fall of the floating platform 2, compared with the ballast method of filling and discharging seawater, it is faster and more sensitive and is beneficial for combating extreme weather.

[0043] It should be noted that the cabin 7 in the embodiment of the present application is located below the floating platform 2, that is, at the sea surface. The cabin 7 has an opening, and the opening of the cabin 7 is opened downward, and seawater can directly enter the cabin 7 through the opening. The opening of the cabin 7 can reduce the amount of material used in the floating platform 2 and save costs. During normal operation, the top surface of the cabin 7 is below the horizontal plane, there is no air in the airbag 9, the floating platform 2 has a deep draft and good stability, which is conducive to the stable power generation of the photovoltaic module 1. In some embodiments, the upper cabin 7 can also be opened on the side of the floating platform 2. The opening on the cabin 7 can also be opened on the side of the cabin 7, as long as the entry and exit of seawater can be achieved.

[0044] like Figures 2 to 4As shown, in some embodiments, in order to ensure the stability of the floating platform 2, a plurality of cabins 7 are provided along the circumference of the floating platform 2, and the cabins 7 are symmetrically arranged on the floating platform 2. It should be noted that when the floating platform 2 is a rectangular structure, the cabins 7 are symmetrical about the long sides and are also symmetrically arranged about the short sides. When processing the cabins 7, a channel can be opened in the circumference of the floating platform 2, and the channel can be divided into a plurality of cabins 7 of the same size by a partition plate. When installing the partition plate, the sealing of each cabin 7 needs to be ensured.

[0045] The airbag 9 is arranged in the cabin 7. By filling and releasing gas in the airbag 9, the seawater in the cabin 7 can be filled and released. The buoyancy of the floating platform 2 can be changed by changing the amount of gas filled in the airbag 9.

[0046] For fixing the airbag 9 in the cabin 7, in some embodiments, a U-shaped eye 8 can be used. When installing the airbag 9, the airbag 9 can be inserted into the U-shaped groove of the U-shaped eye 8, and then the two ends of the U-shaped eye 8 are fixed on the top surface of the cabin 7. In this way, the structure is simple, the structure of the airbag 9 will not be damaged, and the strength of the airbag 9 will not be affected. In some embodiments, the airbag 9 can also be bonded to the inside of the cabin 7, but the bonding method may cause the connection of the airbag 9 to fail under the pressure of seawater.

[0047] The airbags 9 disclosed in the present application are cylindrical airbags, and each airbag 9 is fixed by two U-shaped hanging ears. Only one specific shape and installation method of the airbag 9 are disclosed here. In some embodiments, the airbag 9 can also be set to other shapes and connected by other connection methods.

[0048] Since one airbag 9 is provided in each cabin 7 and these airbags 9 are not connected, even if one airbag 9 is damaged, it will not seriously affect the stability of the floating platform 2. In some embodiments, multiple independently controlled airbags 9 can be provided in each cabin 7. When an airbag 9 is damaged, other airbags 9 in the cabin 7 can be used as supplementary airbags to ensure the stability of the floating platform 2.

[0049] The damping pool type offshore floating photovoltaic platform in the present application is also provided with an adjustment component for adjusting the buoyancy of the airbag 9. The amount of air in the airbag 9 and the amount of seawater in the cabin 7 can be changed by the action of the adjustment component, thereby adjusting the buoyancy of the floating platform 2.

[0050] In some embodiments, the above-mentioned regulating components include: an air pump (not shown in the figure), a pipeline (not shown in the figure) and a controller (not shown in the figure). Among them, the air pump is installed on the floating platform 2 as a power structure to avoid the influence of seawater on the air pump when the air pump is installed in the cabin 7, thereby ensuring the service life of the air pump. The pipeline connects the air pump and the airbag 9, and the gas is transported to the airbag 9 through the pipeline through the operation of the air pump. In order to control the amount of gas input into the airbag 9, a valve is provided on the pipeline, and the valve is a valve that can control the on and off of the pipeline. The valve is connected to the controller in communication, and the start and stop of the valve are controlled by the controller to realize automatic control, avoid manual operation, and reduce the labor intensity of the operator.

[0051] In order to reduce the weight of the floating platform 2 and improve the movement performance of the floating platform 2, in the embodiment of the present application, the floating platform 2 is set as a frame structure. In some embodiments, an alloy frame structure is used. The use of alloy materials can ensure the structural strength of the floating platform 2 and reduce the cost compared to the concrete structure. In some embodiments, the floating platform 2 can be set as a steel frame buoy to reduce the corrosion of the floating platform 2 by seawater.

[0052] A plurality of moon pools are opened in the middle of the floating platform 2 to form a damping pool 3. The existence of the damping pool 3 can reduce the amount of steel used, while increasing the hydrodynamic damping of the floating platform 2 and improving the movement performance of the rigid floating body.

[0053] like Figure 8 As shown, the floating platform 2 is provided with a first heave plate 31 at the edge of the damping pool 3, and the first heave plate 31 is arranged circumferentially along the edge of the damping pool 3. In order to ensure the installation strength of the first heave plate 31, the damping pool type offshore floating photovoltaic platform is also provided with a first stiffening rib 32 for connecting the first heave plate 31 and the floating platform 2. After the first heave plate 31 is installed, the first stiffening rib 32 is perpendicular to the floating platform 2, and the first stiffening rib 32 is a triangular structure, one side of which is fitted and connected to the first heave plate 31, and the other side is fitted and connected to the floating platform 2. The stability of the triangle is used to increase the installation strength of the first heave plate 31.

[0054] The damping pool type offshore floating photovoltaic platform in the present application also includes a second heave plate 5 arranged on the outer periphery of the floating platform 2. By setting the second heave plate 5, the additional mass and additional damping of the floating platform 2 can be further increased, thereby improving the motion performance of the floating platform 2. It should be noted that the second heave plate 5 is arranged perpendicular to the floating platform 2. In order to improve the connection strength between the second heave plate 5 and the floating platform 2, in some embodiments, the second heave plate 5 and the floating platform 2 are connected by a second stiffening rib 4. After the second heave plate 5 is installed, the second stiffening rib 4 is perpendicular to the floating platform 2, and the second stiffening rib 4 is a triangular structure, one side of which is fitted and connected to the second heave plate 5, and the other side is fitted and connected to the floating platform 2. The stability of the triangle is used to increase the installation strength of the second heave plate 5.

[0055] By respectively arranging the second heave plate 5 and the first heave plate 31 on the outer circle of the barge-type floating platform 2 and the inner circle of the damping pool 3, the presence of the heave plate will not significantly increase the steel consumption of the barge-type floating platform 2, but can increase the additional mass and additional damping of the barge-type floating platform 2, further improving the movement performance of the floating platform 2, which is beneficial to photovoltaic power generation.

[0056] In some embodiments, the photovoltaic assembly 1 disclosed in the present application includes a photovoltaic panel 11, a photovoltaic panel bracket 12 and a photovoltaic inverter 13. The photovoltaic panel 11 is tiltedly mounted on the photovoltaic panel bracket 12, and the photovoltaic panel bracket 11 is fixed to the upper surface of the floating platform 2. The photovoltaic panel bracket 12 has a certain height, and the specific height needs to be determined according to the sea conditions and the freeboard of the floating platform 2, which can ensure that the photovoltaic panel 11 is sufficiently far from the still water surface, so that the photovoltaic panel 11 is not affected by wave impact and splashing in the working state.
