DETAILED DESCRIPTION

[0012] The present invention is described in detail below in conjunction with 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.

[0013] like Figure 1 — Figure 4 As shown, a water level adaptive offshore photovoltaic energy foundation includes a connecting piece 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. The height adjustment rods 5 are connected by the steel truss 6. The angle adjuster 4 is arranged at the top of the height adjustment rod 5, the inclined beam 3 is arranged on the angle adjuster 4, the connecting piece 2 is arranged on the inclined beam 3, and the photovoltaic panel 1 is laid on the connecting piece 2.

[0014] This scheme consists of a group anchor foundation composed of four suction anchor foundations 7 (the suction anchor foundation is sunk by suction pump, which has high work efficiency). The angle adjuster 4 is a conventional adjuster, which can be directly purchased on the market. The angle of the angle adjuster can be adjusted adaptively. Under normal environmental loads, the optimal angle is maintained at 5°. The top of the suction anchor foundation 7 is fixedly connected with a rigid height adjustment rod 5, and the height adjustment rods 5 are connected by a steel truss 6. The maximum height is kept consistent. The height adjustment rod 5 is stretched up and down and the angle adjuster 4 works together to change the height and tilt angle according to the external environment such as the water level. During installation, "self-weight installation" or "self-weight + negative pressure installation" is selected. Through geological survey, it is determined that the stratum of the proposed area is relatively flat. The photovoltaic upper structure and the lower suction anchor foundation are prefabricated and assembled on land as a whole, transported to the sea by barge, and sunk by self-weight. According to the actual conditions of the project, it is selected whether it needs to rely on suction pumps to sink and penetrate, so as to achieve one-step installation. In actual installation, aluminum alloy blocks can be used to lay photovoltaic panels.

[0015] Furthermore, there are four suction anchor foundations 7, each of which includes a column 71 with an open bottom, a suction pump port 72 is arranged in the column 71, and a suction pump is arranged 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 arranging 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 by 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.

[0016] 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.

[0017] 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.

[0018] 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 .

[0019] Furthermore, the connecting member 2 includes two C-shaped connecting rods 21 arranged opposite to each other, 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 an elastic washer, which is tightened securely and does not retreat.

[0020] The above specific implementation modes are used to explain the present invention rather than to limit the present invention. Any modification and change 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.
