[0024] This application discloses a villa roof structure, such as Figure 1 and Figure 2 As shown, it includes a roof body 1, a mounting frame 2 installed on the top of the roof body 1, and a photovoltaic module 3 installed on the top of the mounting frame 2; the photovoltaic module 3 includes a photovoltaic panel 31, and a cleaning device 4 for cleaning the top surface of the photovoltaic panel 31 is installed on the mounting frame 2.
[0025] like Figure 1 and Figure 2 As shown, the cleaning device 4 includes two fixed frames 41 respectively installed on both sides of the mounting frame 2, two drive motors 42 respectively installed on one end of the two fixed frames 41, and lead screws 43 respectively fixed to the output shafts of the two drive motors 42; the two drive motors 42 are synchronously controlled by a controller, the two lead screws 43 are rotatably connected to the two fixed frames 41 respectively, and each lead screw 43 is threaded with a movable plate 44. A shielding frame 45 for covering the photovoltaic panel 31 is fixed between the two movable plates 44. A scraper 46 is fixed to the inner top of the shielding frame 45, and the end of the scraper 46 away from the movable frame abuts against the top surface of the photovoltaic panel 31. When the top surface of the photovoltaic panel 31 needs to be cleaned, the drive motor 42 first drives the lead screw 43 to rotate. The rotation of the lead screw 43 drives the moving plate 44 to move. The movement of the moving plate 44 drives the shading frame 45 to move. The movement of the shading frame 45 drives the scraper 46 to slide on the top surface of the photovoltaic panel 31. The scraper 46 sliding on the top surface of the photovoltaic panel 31 can clean the top surface of the photovoltaic panel 31. In summary, the cleaning device 4 facilitates the cleaning of the top surface of the photovoltaic panel 31. In addition, the shading frame 45 facilitates the shading of the photovoltaic panel 31 during heavy or moderate snowfall, so that the photovoltaic panel 31 can be put into use in a timely manner when the snowfall stops.
[0026] like Figure 2 and Figure 3 As shown, the bottom and left side openings of the shielding frame 45 are provided, and a dust-absorbing mechanism 5 for dust removal is installed on the top of the shielding frame 45. The dust-absorbing mechanism 5 is provided to facilitate the absorption of dust when the scraper 46 cleans the top surface of the photovoltaic panel 31.
[0027] like Figure 2 and Figure 3As shown, the dust collection mechanism 5 includes an air pump 51 installed on the top of the shielding frame 45, an air inlet pipe 52 connected to the air inlet of the air pump 51, and an air outlet pipe 53 connected to the air outlet of the air pump 51. A dust collection assembly 6 is installed on the air inlet pipe 52. The end of the air inlet pipe 52 away from the air pump 51 extends into the shielding frame 45 and is fixedly connected to a suction hood 54. The end of the air outlet pipe 53 away from the air pump 51 extends into the shielding frame 45. When dust needs to be collected, the air pump 51 is started first. At this time, the dust enters the dust collection assembly 6 through the suction hood 54, thus collecting the dust. In addition, the gas filtered by the dust collection assembly 6 is blown towards the photovoltaic panel 31 through the air outlet pipe 53, which can more thoroughly clean the dust on the top surface of the photovoltaic panel 31. In summary, the dust collection mechanism 5 is designed to facilitate dust collection.
[0028] like Figure 2 and Figure 3 As shown, the dust collection assembly 6 includes a dust collection box 61 connected to the air intake pipe 52, a cover plate 62 bolted to the top of the dust collection box 61, a sealing ring 63 installed between the cover plate 62 and the dust collection box 61, a filter plate 64 vertically fixed to the bottom of the cover plate 62, and a collection box 65 installed on the filter plate 64. The filter plate 64 is designed to block dust, and the collection box 65 is designed to collect the dust blocked by the filter plate 64. The cover plate 62 is designed to allow the filter plate 64 and the collection box 65 to be removed together for cleaning.
[0029] like Figure 2 and Figure 4 As shown, the mounting frame 2 is equipped with a buffer mechanism 7 for cushioning the shielding frame 45. The buffer mechanism 7 includes a connecting plate 71 fixed to the top of the mounting frame 2, a fixing plate 72 vertically fixed to the top of the end of the connecting plate 71 away from the photovoltaic panel 31, a buffer plate 73 slidably connected to the top of the connecting plate 71, and a plurality of first buffer springs 74 fixed between the buffer plate 73 and the fixing plate 72. A damping tube 75 is fixedly connected through the fixing plate 72, and a damping rod 76 is fixedly connected to the end of the buffer plate 73 near the damping tube 75. The damping rod 76 is frictionally slidably connected to the inside of the damping tube 75. The end of the shielding frame 45 away from the photovoltaic panel 31 can abut against the buffer plate 73. The buffer plate 73 and the first buffer springs 74 facilitate the cushioning of the end of the shielding frame 45 away from the photovoltaic panel 31; the damping rod 76 and the damping tube 75 facilitate the guidance of the buffer plate 73.

The support mechanism 8 includes a through hole 81 on the connecting plate 71, a rack 82 slidably connected to the through hole 81, a transmission assembly 9 installed at the bottom of the connecting plate 71 to drive the rack 82 to move, and a support plate 83 installed at the top of the rack 82. Support blocks 84 are fixed to both sides of the rack 82, and a support spring 85 is fixed to the bottom of each support block 84. When it is necessary to support the end of the shading frame 45 away from the photovoltaic panel 31, the transmission assembly 9 first drives the rack 82 to move upward. The upward movement of the rack 82 drives the support plate 83 to move upward, and the upward movement of the support plate 83 can support the end of the shading frame 45 away from the photovoltaic panel 31. In summary, the support mechanism 8 facilitates the support of the end of the shading frame 45 away from the photovoltaic panel 31. In addition, the support blocks 84 and the support spring 85 facilitate the support of the rack 82.
[0031] like Figure 4 and Figure 5 As shown, the transmission assembly 9 includes a connecting pipe 91 rotatably connected to the bottom of the connecting plate 71 via a bearing, a gear 92 sleeved and fixed to the outer wall of the connecting pipe 91, and a moving rod 93 disposed inside the connecting pipe 91; the gear 92 meshes with the rack 82, and multiple spiral blocks 931 are sequentially fixed to the side wall of the moving rod 93 along its circumference, and multiple spiral grooves 911 are sequentially opened inside the connecting pipe 91 along its circumference, with each spiral block 931 corresponding to a spiral groove 911; one end of the damping rod 76 is fixed to an intermediate plate 94, and the end of the moving rod 93 away from the connecting pipe 91 is fixed to the intermediate plate 94. When the shielding frame 45 pushes the buffer plate 73 to move, the buffer plate 73 drives the damping rod 76 to move. The movement of the damping rod 76 drives the intermediate plate 94 to move. The movement of the intermediate plate 94 drives the moving rod 93 to move. Then, under the action of the spiral block 931 and the spiral groove 911, the moving rod 93 drives the connecting pipe 91 to rotate. The rotation of the connecting pipe 91 drives the gear 92 to rotate. The rotation of the gear 92 can drive the rack 82 to move. In summary, the transmission component 9 is provided to facilitate the movement of the rack 82.
[0032] like Figure 4 and Figure 6As shown, a support rod 831 is fixedly connected to the bottom of the support plate 83. A first through hole 821 for the support rod 831 to pass through is opened at the top of the rack 82. A sliding plate 822 is bolted to the bottom of the support rod 831 by a countersunk bolt. An insert block 832 is fixedly connected to the bottom of the support rod 831. A slot 823 for the insert block 832 to be inserted is opened at the top of the sliding plate 822. The insert block 832 is bolted to the slot 823 by a countersunk bolt. A second through hole 824 for the sliding plate 822 to slide is opened on the side wall of the first through hole 821. A connecting rod 825 is fixedly connected to the bottom of the sliding plate 822, and a second buffer spring 826 is sleeved on the connecting rod 825. The support rod 831, sliding plate 822, and second buffer spring 826 facilitate buffering of the support plate 83.
