Description

Technical Field

[0001] This utility model relates to the field of waterborne photovoltaic installation technology, specifically to a floating support for waterborne photovoltaic systems. Background Technology

[0002] A photovoltaic (PV) power station is a power generation system that utilizes solar energy and employs special materials such as crystalline silicon panels and electronic components like inverters. It is connected to the power grid and transmits electricity to it. Water-based PV power stations, covering the largest area of ​​the Earth's surface, are emerging. However, water-based PV systems are significantly affected by strong winds and waves. In current technology, floating supports are generally assembled from multiple planar floating bodies. Most of these floating bodies are located above the water surface and often cannot withstand large wave impacts. For example, when encountering waves several meters high, the impact force can cause the supports to capsize or overturn. Furthermore, because the PV supports are close to the water surface, the PV modules installed on them are also easily damaged by waves. Overly dense assembly of planar floating bodies can also negatively impact water bodies suitable for fish-solar hybrid systems. Utility Model Content

[0003] Technical objective: To address the shortcomings of existing floating photovoltaic installation structures, this utility model discloses a floating photovoltaic support frame.

[0004] Technical solution: To achieve the above technical objectives, the present invention adopts the following technical solution: A floating photovoltaic support structure includes a floating body structure for connecting to and maintaining the photovoltaic panel on the water surface. The floating body structure has a stabilizing block at its horizontal interface with the water surface to maintain the angle of the floating body structure at the water surface. A ballast block is provided below the floating body structure to adjust the overall center of gravity of the floating support. The ballast block is connected to the floating body structure through a column and is fixed to the bottom end of the column. The ballast block keeps the center of gravity of the floating support in the center position and below the water surface.

[0005] Preferably, the ballast block of this invention has a specific gravity greater than 1.0 t / m³. 3 .

[0006] Preferably, the column of this utility model is made of corrosion-resistant alloy material with a diameter of DN150-DN400.

[0007] Preferably, the stabilizing blocks of this invention are symmetrically arranged about the floating support, the center of gravity of the floating support is located in the vertical plane where the stabilizing blocks are located, and the stabilizing blocks are hollow and sealed structures filled with water.

[0008] Preferably, the floating structure of this utility model is a hollow and sealed structure, and the maximum buoyancy generated by the floating structure is greater than twice the overall weight of the floating support.

[0009] Preferably, the cross-section of the floating structure of this utility model is circular, polygonal, or circular ring-shaped.

[0010] Preferably, when the cross-section of the floating structure of this utility model is circular or polygonal, the photovoltaic panel is fixed to the top of the floating structure by a plate support, and the stabilizing blocks are symmetrically installed on both sides of the floating structure.

[0011] Preferably, the vertical cross-section of the floating structure of this utility model adopts an inverted trapezoidal structure.

[0012] Preferably, when the cross-section of the floating structure of this utility model is a circular ring shape, the photovoltaic panel is fixed to the top of the column by the plate support, the stabilizing blocks are symmetrically located on both sides of the column, the floating structure is connected to the column by the connecting rod, and the stabilizing blocks are fixed on the outside of the floating structure.

[0013] Beneficial effects: This utility model's floating photovoltaic support system incorporates stabilizing blocks and ballast blocks. The ballast blocks lower the center of gravity of the floating support system. When strong winds blow the photovoltaic panels or waves act on the support system, the column tilts. As the floating support system swings, part of the stabilizing block emerges above the water surface, while the float on the other side sinks, increasing the water surface area. The center of gravity of the ballast block deviates from the vertical line of the floating support system's center of gravity. The stabilizing block, ballast block, and float generate a torque opposite to the tilting direction, restoring the column to a vertical position, thereby maintaining the stability of the floating support system.

Detailed Implementation

[0016] Reference will now be made in detail to embodiments of the present disclosure, one or more of which are set forth herein. Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and not by way of limitation. Rather, the following description provides convenient illustrations for implementing exemplary embodiments of the present disclosure. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the teachings of the present disclosure without departing from the scope or spirit of the present disclosure.

[0017] like Figures 1-4 As shown, this utility model discloses a floating photovoltaic support for water, including a floating structure 1 for connecting with a photovoltaic panel 5 and keeping it floating on the water surface. The floating structure 1 is provided with a stabilizing block 2 at the junction with the water surface along the horizontal direction to maintain the angle of the floating structure 1 at the water surface. A ballast block 3 is provided below the floating structure 1 to adjust the overall center of gravity of the floating support. The ballast block 3 is connected to the floating structure 1 through a column 4 and is fixed to the bottom end of the column 4. The ballast block 3 keeps the center of gravity of the floating support in the center position and below the water surface.

[0018] This invention lowers the center of gravity of the floating support by setting ballast block 3, thereby improving the stability of the overall structure in the floating state. When affected by wind and waves, ballast block 3 and stabilizing block 2 can generate a restoring torque, thereby maintaining the stability of the floating support.

[0019] The ballast block 3 of this invention has a specific gravity greater than 1.0 t / m³. 3 Concrete, stone, or other materials with higher density are preferred to reduce the impact of water buoyancy on the movement of ballast block 3. Column 4 requires high rigidity and is made of corrosion-resistant alloy material of DN150-DN400, preferably aluminum alloy material of DN200.

[0020] In this invention, the stabilizing block 2 is symmetrically arranged about the floating support. The center of gravity of the floating support is located in the vertical plane where the stabilizing block 2 is located. The stabilizing block 2 is a hollow, sealed structure, and its cross-sectional shape is preferably trapezoidal. Water is filled inside the stabilizing block 2, which can make the stabilizing block 2 float stably on the water surface and located below the water surface. When the floating structure tilts, the stabilizing block 2 and the ballast block 3 generate torque at different positions of the floating structure to achieve rapid reset.

[0021] The floating structure 1 of this utility model is a hollow and sealed structure. The maximum buoyancy generated by the floating structure 1 is more than twice the overall weight of the floating support, and it is used to bear the load of the floating support, photovoltaic panel and operation and maintenance.

[0022] The cross-section of the floating structure 1 of this utility model is circular, polygonal, or circular ring-shaped. Example

[0023] like Figure 1As shown, the cross-section of the floating structure 1 is circular. The photovoltaic panel 5 is fixed to the top of the floating structure by the plate support 6. The stabilizing block 2 is symmetrically installed on both sides of the floating structure. The column 4 is located on the vertical line where the center of gravity of the floating structure is located, and the lower end is connected to the ballast block 3.

[0024] In this state, when the floating support tilts, the buoyancy on the left and right sides will change after the circular structure tilts. The part of the stabilizing block 2 that is exposed in the water will generate a rotational torque. Combined with the torque generated by the ballast block 3, the floating support can be restored to a balanced state. Example

[0025] like Figure 2 As shown, the cross-section of the floating structure 1 is an inverted trapezoidal shape. The photovoltaic panel 5 is fixed to the top of the floating structure by the plate support 6. The stabilizing block 2 is symmetrically installed on both sides of the floating structure. The column 4 is located on the vertical line where the center of gravity of the floating structure is located, and the lower end is connected to the ballast block 3.

[0026] In this state, when the floating support tilts, the volume of water discharged on both sides changes after the inverted trapezoidal shape tilts, and the buoyancy on the left and right sides changes. The part of the stabilizing block 2 that is exposed in the water generates a rotational torque, which, together with the torque generated by the ballast block 3, can restore the floating support to a balanced state. Example

[0027] like Figure 3 As shown, the cross-section of the floating structure 1 is a right trapezoid. The photovoltaic panel 5 is fixed on the inclined surface of the right trapezoid by the plate support 6. The stabilizing block 2 is symmetrically installed on both sides of the floating structure. The column 4 is located on the vertical line where the center of gravity of the floating structure is located, and the lower end is connected to the ballast block 3.

[0028] In this state, when the floating support tilts, the part of the stabilizing block 2 that is exposed in the water generates a rotational torque, which, together with the torque generated by the ballast block 3, can restore the floating support to a balanced state. Example

[0029] like Figure 4 As shown, the floating structure 1 is a circular ring shape and is set around the floating support. The photovoltaic panel 5 is fixed to the top of the column 4 through the plate support 6. The stabilizing block 2 is symmetrically located on both sides of the column 4. The floating structure 1 is connected to the column 4 through the connecting rod. The stabilizing block 2 is fixed on the outside of the floating structure 1.

[0030] When the floating support tilts, the torque generated by the stabilizing block 2 and the ballast block 3 can also be used to reset the floating support and maintain stable support for the photovoltaic panel.

[0031] By using the floating structure of this utility model, various types of floating support structures can be applied to ensure the stability of photovoltaic panels installed on the water surface and avoid side tipping or overturning.

[0032] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
