[0002] Currently, photovoltaic panels, also known as solar panels or photoelectric panels, are devices that can convert solar energy into electrical energy. They are panels composed of multiple solar cells and use special materials to convert solar energy into direct current, which can be used for power generation or charging.

[0003] In order to save space costs, solar photovoltaic panels will be built on the lake to collect a large amount of sunlight and convert it into electricity to supply power to the city.

[0004] In order to protect the photovoltaic panels in the lake, it is necessary to install a protective fence on the outside of the photovoltaic panels. However, it is difficult to adjust the height of the protective fence on the market, which makes it difficult to protect the photovoltaic panels when the water level of the lake changes. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0007] The adjustable protective fence includes first slip rings slidably installed on the outer walls of two groups of the brackets, a connecting frame fixedly installed between the two groups of the first slip rings, a plurality of groups of equidistantly distributed fence frames fixedly installed on the top of the connecting frame, and a floating ball fixedly installed on the bottom of the connecting frame.

[0008] As an optional solution of the technical solution of the present application, the outer walls of the two groups of brackets are engraved with scale lines to monitor the water level of the lake.

[0009] As an optional solution of the technical solution of the present application, second slip rings are slidably installed on the top of the two groups of brackets, and a limiting frame is fixedly installed between the two groups of second slip rings.

[0010] As an optional solution of the technical solution of the present application, a plurality of groups of equally spaced limiting holes are provided on the limiting frame, and the plurality of groups of limiting holes are movably connected to each group of the fence frames respectively, so that the fence frames can be limited.

[0011] As an optional solution of the technical solution of the present application, screw holes are provided in the middle of the side walls of the two groups of the second slip rings, and bolts are threadedly connected in the two groups of the screw holes to position the second slip rings.
