[0024] like Figure 1-Figure 12 As shown, as a preferred embodiment of the present invention, a fresh air inlet 303 is provided at the bottom of the cavity 107, a avoidance groove 302 cooperating with the fresh air inlet 303 is provided on the sliding frame 204, a through hole 301 is provided at one end of the protective cylinder 105 located in the cavity 107, a filter screen is installed on the through hole 301, and when the opening 106 of the protective cylinder 105 is rotated to face upward, the protective cylinder 105 and the mounting frame 103 form a ventilation pipe, and the ventilation pipe is connected with the cavity 107 through the through hole 301.

[0025] In the embodiment of the present invention, the protective tube 105 is in the Fig.10In the state, the mounting frame 103 and the protective cylinder 105 form a fresh air channel, and the outside air enters the fresh air channel, passes through the through hole 301 and enters the cavity 107, and the filter screen 1 filters the outside air. The air in the cavity 107 enters the room through the avoidance groove 302 and the fresh air outlet 303, thereby promoting indoor air circulation and supplying fresh air to the room. When the protective cylinder 105 rotates, the protective cylinder 105 drives the filter screen 1 to rotate, and the filter screen 1 rotates relative to the mounting frame 103. The mounting frame 103 scrapes off dust and other impurities on the filter screen 1, thereby cleaning the filter screen 1 and improving the quality of indoor fresh air.

After the outside air is filtered by the filter screen 2, it enters the cavity 107 from the air inlet 401, and the filtered air enters the room through the avoidance groove 302 and the fresh air outlet 303, thereby promoting the indoor air circulation and supplying fresh air to the room. In severe weather such as strong winds, hail and freezing rain, the motor 207 drives the screw rod 206 to rotate. Under the guidance of the guide groove 203, the screw rod 206 drives the sliding frame 204 to move through threaded transmission, and the sliding frame 204 drives the rack 205 to move. The rack 205 drives the gear 202 to rotate the rod, and the gear 202 drives the installation cylinder 201 to rotate.

A guide groove is formed between every two protective cylinders 105, and the guide groove can guide and discharge rainwater on the roof 101, improve the drainage efficiency of the roof 101, avoid water accumulation on the roof 101, thereby preventing leakage and damage to the roof 101. Through timely drainage, the guide groove protects the structure of the roof 101 and the house, and prevents structural damage caused by water accumulation. The avoidance groove 302 is misaligned with the fresh air inlet 303, thereby blocking the fresh air inlet 303. The mounting frame 103 and the protective tube 105 form a cleaning channel. At this time, the air in the cavity 107 passes through the filter mesh 1 and the through hole 301 to enter the cleaning channel, and then uses the wind force to clean the photovoltaic panel, thereby blowing away dust and other impurities on the photovoltaic panel, thereby improving the working efficiency of the photovoltaic panel, and when the air passes through the filter mesh 1, the filter mesh 1 is backwashed, and the filter mesh is cleaned together, thereby improving the filtering effect of the filter mesh 1, avoiding impurities from clogging the filter mesh 1, and improving the quality of indoor fresh air.
