[0021] The utility model will be further explained in detail in combination with the drawings and through the embodiment, and the following embodiment is the explanation of the utility model and the utility model is not limited to the following embodiment.

[0022] The utility model embodiment includes glass steel container 1, pre-buried reinforcing steel 2, photovoltaic support steel column 3 and glass steel cover 6.

[0023] The glass steel container 1 is cuboid, made of glass steel material, mainly used for underwater corrosion prevention. A partition plate 8 is fixed in the glass steel container 1, which divides the space in the glass steel container 1 into a ballast tank 11 and a concrete tank 12. The ballast tank 11 is multiple, located around the concrete tank 12. In this embodiment, the ballast tank 11 is four. The bottom of the glass steel container 1 is wavy, which increases the contact area between the foundation bottom plate and the soil layer in the water purification tank, plays a role in increasing the lateral force and preventing water and soil loss. The glass steel container 1 is provided with a 1cm hole 7 around the side surface, which is densely and orderly arranged, so that the water flow in the water purification process can directly pass through the foundation, without hindering or changing the water flow path due to the arrangement of the photovoltaic foundation, so that the water purification function of the water purification tank is not affected.

[0024] The graded stone layer 5 is filled in the ballast tank 11, which plays a ballast role. The graded stone layer 5 can be made of limestone graded stone planted around the environment of the foundation, and the structure of the graded stone layer 5 in the ballast tank 11 is the same as that of the soil layer around the environment.

[0025] The embedded steel bar 2 is welded and fixed at the bottom of the photovoltaic support steel column 3; the concrete 4 is poured in the concrete tank 12, and the bottom of the photovoltaic support steel column 3 and the embedded steel bar 2 are embedded in the concrete 4, which plays a role in force transmission. The photovoltaic support steel column 3 is made of square tube. The photovoltaic support steel column 3 is used to support the photovoltaic power generation system.

[0026] The glass steel cover 6 is made of glass steel material, covers the glass steel container 1, covers the ballast tank 11, and is fixed around by self-tapping nails to prevent the graded stone layer 5 from flowing away. The glass steel cover 6 is a pair of oppositely arranged. The glass steel cover 6 is provided with a notch 9 in the middle. The concrete 4 is fixed and will not flow away, so the upper part of the concrete tank 12 can be without cover, which not only saves materials, but also makes installation more convenient.

[0027] In addition, it should be noted that the specific embodiments described in the specification, the shape of the parts, the name taken, etc. can be different, and the above described in the specification is only an example of the structure of the utility model. Any equivalent change or simple change made according to the structure, features and principles described in the utility model patent concept is included in the protection scope of the utility model patent. The person skilled in the art of the utility model can make various modifications or supplements to the described specific embodiments or use similar ways to replace, as long as it does not deviate from the structure of the utility model or beyond the scope defined in the claims, which shall belong to the protection scope of the utility model.
