[0027] Please also read Figure 1 and Figure 2 Now, the rooftop solar power generation device provided by the utility model is described. The rooftop solar power generation device comprises a mounting bracket 1 fixed on the roof and a solar panel 2 fixed on the mounting bracket 1, and also comprises a cleaning brush 3 and a driving assembly 4. The cleaning brush 3 is slidably connected to the mounting bracket 1. When the cleaning brush 3 slides, one end of the cleaning brush 3 for cleaning can abut against the upper surface 21 of the solar panel 2. The driving assembly 4 is used to drive the cleaning brush 3 to slide.

[0028] Compared with the prior art, the rooftop solar power generation device provided by the utility model has an initial state of the cleaning brush 3 being located on one side of the solar panel 2 along the sliding direction of the cleaning brush 3. When the upper surface 21 of the solar panel 2 needs to be cleaned, the driving component 4 drives the cleaning brush 3 to slide, so that the end of the cleaning brush 3 used for cleaning is in contact with the upper surface 21 of the solar panel 2. As the cleaning brush 3 slides, the upper surface 21 of the solar panel 2 is cleaned. Since there is no need to manually clean the upper surface 21 of the solar panel 2, it is possible to avoid manually cleaning the solar panel 2 on the roof, and the problem of dust raised during cleaning endangering the health of the operator can be avoided.

[0029] In some embodiments, see above Figures 2 to 5 , the rooftop solar power generation device also includes a collecting hood 5, a connecting pipe 6 and an exhaust assembly 7. The collecting hood 5 is sleeved outside the cleaning brush 3 and fixedly connected to the cleaning brush 3. When the end of the cleaning brush 3 for cleaning abuts against the upper surface 21 of the solar panel 2, the open end of the collecting hood 5 faces the upper surface 21 of the solar panel 2. One end of the connecting pipe 6 is fixedly connected to the collecting hood 5 and communicated with the inside of the collecting hood 5. The exhaust assembly 7 is communicated with the other end of the connecting pipe 6. When the cleaning brush 3 cleans the upper surface 21 of the solar panel 2, dust will be raised, and the dust may fall back on the upper surface 21 of the solar panel 2, thereby affecting the cleaning effect. In this embodiment, the exhaust assembly 7 extracts the air in the collecting hood 5 through the connecting pipe 6, and the raised dust enters the connecting pipe 6 with the air flow under the negative pressure in the collecting hood 5, thereby preventing the raised dust from falling back on the upper surface 21 of the solar panel 2. In this embodiment, there is a channel for airflow between the collecting hood 5 and the cleaning brush 3 and connected to the connecting pipe 6.

[0030] In some embodiments, see Figures 3 to 5 , the connecting pipe 6 has an inclined section 61 which is arranged at an angle with the horizontal plane, and the exhaust assembly 7 includes a collection bottle 71, a filter screen 72 and an exhaust fan 73. The mouth of the collection bottle 71 is slidably sleeved outside the lower end of the inclined section 61, and the bottom of the collection bottle 71 is provided with a vent 711. The filter screen 72 is located in the collection bottle 71, and the filter screen 72 is fixedly fitted with the bottom of the collection bottle 71, and the filter screen 72 covers the vent 711. The exhaust fan 73 is fixedly arranged on the bottom surface of the collection bottle 71 and covers the vent 711. The mouth of the collection bottle 71 is tilted upward. After the exhaust fan 73 is started, the dust in the collection cover 5 enters the connecting pipe 6 and the collection bottle 71 in sequence with the air flow, and the air flow is filtered by the filter screen 72 and flows out of the collection bottle 71 from the vent 711, and the dust remains in the collection bottle 71, thereby collecting the dust.

[0031] In some embodiments, see Figure 3The rooftop solar power generation device also includes a first fixing member 8, a second fixing member 9 and a limiting shaft 10. The first fixing member 8 is fixedly connected to the collecting bottle 71. The second fixing member 9 is fixedly connected to the collecting cover 5. The limiting shaft 10 is perpendicular to the inclined section 61, and the limiting shaft 10 is slidably inserted into the first fixing member 8 and the second fixing member 9. The second fixing member 9 limits the sliding of the collecting bottle 71 through the first fixing member 8 and the limiting shaft 10, thereby preventing the bottle mouth of the collecting bottle 71 from sliding out of the inclined section 61. When the dust in the collecting bottle 71 needs to be processed, the limiting shaft 10 is driven to slide out of the first fixing member 8, and then the bottle mouth of the collecting bottle 71 is made to slide out of the inclined section 61, and then the dust in the collecting bottle 71 can be processed.

[0032] In some embodiments, see Figure 3 The side wall of the limiting shaft 10 is provided with a limiting portion 101 protruding outward, and the limiting portion 101 is located between the first fixing member 8 and the second fixing member 9. The rooftop solar power generation device also includes a compression spring 110. The compression spring 110 is sleeved on the limiting shaft 10, and the two ends of the compression spring 110 are respectively in contact with the limiting portion 101 and the second fixing member 9. The resilience of the compression spring 110 can increase the resistance of the limiting shaft 10 to slide out of the first fixing member 8.

[0033] In some embodiments, see Figure 3 The rooftop solar power generation device further comprises a pull ring 120. The pull ring 120 is located on a side of the second fixing member 9 away from the first fixing member 8, and the pull ring 120 is fixedly connected to the limiting shaft 10. It is convenient to drive the limiting shaft 10 to slide out of the first fixing member 8 through the pull ring 120.

[0034] In some embodiments, see Figure 3 The rooftop solar power generation device further includes a fixing ring 130 and an annular sealing gasket 140. The fixing ring 130 is sleeved and fixed outside the inclined section 61. The annular sealing gasket 140 is sleeved outside the inclined section 61 and is located between the fixing ring 130 and the bottle mouth of the collecting bottle 71. The sealing between the inclined section 61 and the bottle mouth of the collecting bottle 71 can be ensured by the fixing ring 130 and the bottle mouth of the collecting bottle 71 cooperating to squeeze the annular sealing gasket 140.

[0035] In some embodiments, the annular sealing gasket 140 is fixedly connected to the fixing ring 130. In this way, when the bottle mouth of the collecting bottle 71 slides away from the inclined section 61, the annular sealing gasket 140 can be prevented from being lost.

[0036] In some embodiments, see Figure 1The rooftop solar power generation device further includes a fixed shaft 150 and a slider 160. The fixed shaft 150 is arranged along the sliding direction of the cleaning brush 3 and is fixedly connected to the mounting bracket 1. The slider 160 is slidably sleeved on the fixed shaft 150, and the slider 160 is fixedly connected to the collecting cover 5. The sliding connection between the cleaning brush 3 and the mounting bracket 1 can be indirectly achieved through the sliding cooperation between the fixed shaft 150 and the slider 160.

[0037] In the prior art, the solar panel 2 is arranged at an angle with the horizontal plane. In this embodiment, the fixing shaft 150 may also be arranged at an angle with the horizontal plane, and the angle matches the angle between the solar panel 2 and the horizontal plane.

[0038] In some embodiments, the feature driving component 4 may be used as follows: Figure 1 See the structure shown. Figure 1 The driving assembly 4 includes a driving screw 41, a screw nut 42 and a driving motor 43. The driving screw 41 is parallel to the fixed shaft 150, and the driving screw 41 is rotatably connected to the mounting bracket 1. The screw nut 42 is threadedly connected to the driving screw 41, and the screw nut 42 is fixedly connected to the collecting cover 5. The driving motor 43 is fixedly arranged on the mounting bracket 1, and the output shaft of the driving motor 43 is connected to the driving screw 41. The output shaft of the driving motor 43 drives the driving screw 41 to rotate, so that the cleaning brush 3 slides along the axial direction of the fixed shaft 150 with the collecting cover 5.
