To this end, the vigorous development of photovoltaic power generation projects is necessary. However, both nearshore and offshore locations often experience water level fluctuations that can render photovoltaic facilities unusable. Therefore, a water-level-adaptive offshore photovoltaic mounting bracket is needed. Utility Model Content

[0018] The present invention will be described in detail below with reference to specific implementation cases. The following implementation cases will help those skilled in the art to further understand the present invention, but will not limit the present invention in any form.

[0019] like Figure 1 — Figure 4 As shown, a water level adaptive offshore photovoltaic energy foundation includes a connector 2, an inclined beam 3, an angle adjuster 4, a height adjustment rod 5, a steel truss 6 and a suction anchor foundation 7. The height adjustment rod 5 is connected to the suction anchor foundation 7, and the height adjustment rods 5 are connected by a steel truss 6. The angle adjuster 4 is set at the top of the height adjustment rod 5, the inclined beam 3 is set on the angle adjuster 4, the connector 2 is set on the inclined beam 3, and the photovoltaic panel 1 is laid on the connector 2.

[0020] This solution consists of a cluster anchor foundation consisting of four suction anchor foundations 7 (which rely on suction pumps for high efficiency). The angle adjusters 4 are commercially available and are adaptively adjustable, maintaining an optimal angle of 5° under normal environmental loads. Rigid height adjustment rods 5 are fixedly attached to the tops of the suction anchor foundations 7. These rods 5 are connected by steel trusses 6, maintaining a consistent maximum height. The rods 5 extend and retract, working in conjunction with the angle adjusters 4 to adjust their height and tilt according to external conditions such as water levels. Installation options include "deadweight installation" or "deadweight + negative pressure installation." Based on geological surveys, if the proposed construction area is relatively flat, the photovoltaic superstructure and lower suction anchor foundations are prefabricated and assembled onshore. The structures are transported to sea by barge and lowered by their own weight. Whether or not suction pumps are used for sinking is determined based on project conditions, enabling a one-step installation. In actual installation, aluminum alloy briquettes can be used to lay the photovoltaic panels.

[0021] Furthermore, there are four suction anchor foundations 7, each of which includes a column 71 with an open bottom, a suction pump port 72 provided in the column 71, and a suction pump provided in the suction pump port. In this embodiment, the suction anchor foundation 7 includes a column 71 with an open bottom, the inner wall of the column 71 can improve the bearing performance by providing stiffening ribs, and the column 71 is provided with a suction pump port above the mud surface elevation, so that the water in the column is discharged through the suction pump to realize the installation of the suction anchor foundation. At the same time, when the environment permits, the suction anchor foundation can also be installed directly by its own weight.

[0022] Furthermore, each suction anchor foundation 7 is connected to a height adjustment rod 5, and the four height adjustment rods 5 are connected by a steel truss 6. The height adjustment rods and the steel truss are both made of stainless steel, which has high strength and corrosion resistance, and improves service life.

[0023] Furthermore, the height adjustment rod 5 is a hydraulic automatic lifting rod, which can adjust the height according to its own weight, and the hydraulic automatic lifting rod has good rigidity and long service life.

[0024] Furthermore, in order to better install and connect the height-adjustable rod, the steel truss 6 is connected to the lower part of the height-adjusting rod 5 .

[0025] Furthermore, the connecting member 2 includes two relatively arranged C-shaped connecting rods 21, each end of the C-shaped connecting rod 21 is connected with a bolt 22, the bolt 22 is connected to the inclined beam 3, and the bolt is equipped with two flat plates and a spring washer, which is tightened firmly and does not retreat.

[0026] The above specific implementation methods are used to illustrate the present invention rather than to limit the present invention. Any modifications and changes made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
