[0028] The first housing 1 includes a first inner cavity 11, a first water injection hole 12 connecting the first inner cavity 11 to the outside, and a first slot 13 provided on the first housing 1.
[0029] Connection mechanism 2, which includes

[0031] The second column 22 is provided with a plurality of spaced second adjustment holes 221. The second column 22 is sleeved with the first column 21. The first adjustment holes 211 and the second adjustment holes 221 are connected by bolts to adjust the extension height of the second column 22 relative to the first column 21.
[0032] An angle connector 23 is hinged to the end of the second column 22 and is used to connect to the photovoltaic module 4.
[0033] This invention provides a photovoltaic counterweight foundation system. During use, water is injected into the first inner cavity through a first water injection hole, increasing the weight of the first housing and replacing the traditional poured concrete foundation. Photovoltaic modules are then installed via a connecting mechanism. Compared to traditional concrete photovoltaic foundations, this system is lightweight, easy to transport, and easy to construct, reducing construction difficulty, site pollution, and improving construction efficiency. Furthermore, the counterweight can be flexibly adjusted as needed; for example, water can be temporarily injected during typhoons to increase the counterweight, while water can be drained during normal times to reduce the load on the roof. In this embodiment, the first and second water injection holes, as well as the drain outlet, are all equipped with covers.
[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the two first housings 1 are placed one behind the other, and the two connecting mechanisms 2 are connected to the front and rear ends of the photovoltaic module. Using first housings of uniform specifications facilitates production and transportation.
[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the first housing 1 further includes a first support 14 disposed in the first inner cavity 11. Two first supports 14 are arranged vertically at intervals and are respectively connected to the bottom surface and top surface of the first inner cavity 11. The first slot 13 is connected to the two first supports 14. This enhances the structural strength of the first housing and the support strength for the slot.
[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the first support 14 includes crossbars 141 and longitudinal bars 142 arranged in a cross shape, and the first support 14 is connected to the four sides of the first inner cavity 11 respectively. This enhances the structural strength of the first housing.
[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the first slot 13 is vertically arranged, with its two ends connected to the connection points of the horizontal bar 141 and the vertical bar 142, respectively. This increases the support strength of the slot.
[0038] Furthermore, as a preferred embodiment of this solution and not a limitation, the first housing 1 is provided with a drain outlet 15, and the crossbar 141 and the vertical bar 142 are provided with through holes 16. This facilitates drainage and reduces obstruction by the first support.
[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a second housing 3, which includes a second inner cavity 31, a second water inlet 32 connecting the second inner cavity 31 to the outside, a second slot 33 disposed on the second housing 3, and a third column 34 disposed on the second slot 33. The first housing 1 and the second housing 3 are placed one behind the other so that the connecting mechanism 2 and the third column 34 are respectively connected to the front and rear ends of the photovoltaic module. The height of the second housing is less than the height of the first housing, which facilitates installation.
[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, the second housing 3 is provided with a second support 35, which connects the bottom and top surfaces, as well as the four sides, of the second inner cavity 31, thereby enhancing the structural strength of the second housing.
[0041] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the first column 21 and the second column 22 are U-shaped, and the first column 21 is sleeved on the second column 22. This results in a simple structure and high strength.
[0042] Furthermore, as a preferred embodiment of this solution and not a limitation, a groove 17 is provided on one side of the first housing 1, and a protrusion 18 is provided on the other side. The groove 17 on one first housing 1 allows the protrusion 18 on another first housing 1 to be inserted. This facilitates the connection of the two first housings and increases the counterweight. Based on the characteristics of photovoltaic panels—low ambient temperature and high conversion efficiency—the first housing array helps to reduce the ambient temperature and improve the power generation efficiency of the photovoltaic panels.
[0043] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
