[0002] Green buildings aim at the coordinated development of people, buildings and the natural environment. While using natural conditions and artificial means to create a good and healthy living environment, they try to control and reduce the use and damage of the natural environment as much as possible, fully reflecting the balance between what is taken from nature and what is returned. In order to achieve the goal of energy saving, solar panels are usually installed on the roofs of green buildings. Solar panels are used to absorb and convert light energy, converting light energy into electrical energy for use by electrical equipment in the building.

[0003] The existing Chinese patent with the announcement number CN214256227U discloses a light collecting device for solar panels on the roof of a building, including a light collecting cover, a light collecting tube and a light expanding cover. The light collecting cover, the light collecting tube and the light expanding cover are all hollow structures. The two ends of the light collecting tube are respectively fixedly inserted into the bottom ends of the light collecting cover and the light expanding cover. A dustproof groove is penetrated through the end of the light collecting cover away from the light collecting tube. A dustproof mechanism is arranged in the dustproof groove, and brackets are arranged on both sides of the light collecting tube.

[0004] With respect to the above-mentioned related technology, the inventors found that there are at least the following problems in the technology: although the above-mentioned technology can prevent dust, when encountering heavy rain, rainwater will directly enter the focusing tube from the light collecting cover, causing rainwater to accumulate above the solar panel, which may affect the life of the device.
