[0003] At present, the invention patent with the publication number of CN114928312A discloses a photovoltaic panel support that can adjust the pitch angle, which can change the inclination of the photovoltaic panel, making the photovoltaic panel more inclined during the cleaning process, so that the dust on the photovoltaic panel is more easily washed away by the water flow under the action of gravity, in order to solve the problem that because the size of one photovoltaic panel is very large, it is difficult for the cleaning personnel to clean all positions of the photovoltaic panel during the cleaning process, and after cleaning, there will still be some dust that will not be washed off by the cleaning water flow, and this part of the dust will remain at some positions on the surface of the photovoltaic panel and still affect the power generation of the photovoltaic panel.

[0004] When the existing photovoltaic support is fixed, the connection between the bottom of the steel support column and the concrete pier generally adopts a hinged form. This type of support needs to add diagonal bracing members to form a basic geometrically invariant system, which requires a large installation space and increases the consumption of steel structures. To cancel the diagonal bracing members and meet the requirements of structural calculation, a column bottom connection device for a photovoltaic support is proposed in this application.
