The periphery of the cleaning pipe (121) has multiple cleaning holes (122) for spraying water onto the solar panel (21). A first water pump (141) is installed in the water storage tank (14). The inlet end of the cleaning pipe (121) is connected to the outlet end of the first water pump (141). A brush strip (123) is slidably installed in the second mounting groove (12). When the solar panel (21) is housed in the receiving groove (11), the brush strip (123) abuts against the surface of the solar panel (21). The brush strip (123) has a sliding component (7) for driving the brush strip (123) to slide and clean the solar panel (21).

2. The green building roof structure according to claim 1, characterized in that: The bottom wall of the second mounting groove (12) is provided with a drain hole (124) that communicates with the water storage tank (14). The bottom wall of the second mounting groove (12) gradually slopes downward from the side away from the drain hole (124) to the side closer to the drain hole (124).

3. The green building roof structure according to claim 2, characterized in that: The water storage tank (14) has a partition plate (142) fixed to its side wall. The partition plate (142) divides the water storage tank (14) into a clean water area (143) and a sewage area (144). The first water pump (141) is located in the clean water area (143). The drainage trough (15) is connected to the clean water area (143). The drainage hole (124) is connected to the sewage area (144). A second water pump (145) is installed in the sewage area (144). A sewage pipe (146) is connected between the second water pump (145) and the collection tank (13). The drainage trough (15) is provided with a filter assembly (8) for filtering foreign objects.

4. A green building roof structure according to claim 3, characterized in that: The filter assembly (8) includes a collection box (81) installed in the opening of the drainage trough (15) and a filter plate (82) installed in the collection box (81).
