There is a sliding mechanism 5, and the cleaning component 6 includes a cleaning roller 601 with a cavity inside. Second bearings 604 are embedded at both ends of the cleaning roller 601. A connecting shaft 605 is installed between the inner surface walls of the two second bearings 604. A molybdenum rod 606 is fixedly connected between the adjacent ends of the two connecting shafts 605 through a flange. A high-resistance heating wire 607 is installed between the outer surfaces of the two connecting shafts 605 and the high-resistance heating wire 607 is located inside the cleaning roller 601. The high-resistance heating wire 607 is electrically connected to an external power supply through a circuit. A plurality of micropores 602 are arranged and distributed on the outer surface of the cleaning roller 601. The outer surface of the cleaning roller 601 A plurality of bristles 603 staggered with the micropores 602 are arranged and fixedly connected, a dual-axis motor 16 is installed at the bottom of the support shell 14 at the center of the rear side, a rotating seat 17 is installed at the bottom of the support shell 14 at both sides of the dual-axis motor 16, a driving shaft 18 extending outward is rotatably connected between the inner surface walls of the rotating seat 17, a driving pulley 19 is installed at the outer end of the driving shaft 18, the output ends on both sides of the dual-axis motor 16 are fixedly connected to the ends of the two driving shafts 18 respectively, and the transmission mechanism 3 includes a clamping block 301, a second bolt 302, a belt 304, a third bolt 305, a first bearing 306 and a guide pulley 307 The third bolt 305 is fixedly installed on the outer surface of the support shell 14 near the front side. A clamping groove 303 is opened inside the clamping block 301 for sleeveing ​​the clamping block 301 on the surface of the connecting shaft 605. The second bolt 302 is fixedly installed above the rear surface of the clamping block 301 for tightening the clamping groove 303. The outer surface of the third bolt 305 is sleeved with a first bearing 306. The outer surface of the first bearing 306 is installed with a guide pulley 307.

[0033] In this embodiment, when the distributed photovoltaic power generation device is used in an area with frequent snowfall and snow accumulates on the surface, after the high-resistance heating wire 607 is powered by an external power supply, the high-resistance heating wire 607 will convert electrical energy into thermal energy and play a role in heating the cleaning roller 601, and part of the hot air will be discharged through the micropores 602 to heat the surface of the photovoltaic panel 15, thereby promoting the melting of ice and snow. During the process, the dual-axis motor 16 at the bottom of the supporting shell 14 is started and the two driving shafts 18 are used to drive the driving pulleys 19 on both sides to rotate. At this time, under the action of friction, the belt 304 on the surface of the driving pulley 19 will move around the surface of the driving pulley 19 and the guide pulley 307, and the belt 304 is fixedly connected to the connecting shaft 605 extending outward from the inside of the cleaning roller 601 through the clamp 301, so that a dragging force on the connecting shaft 605 and the cleaning roller 601 will be generated. , and the moving path of the connecting shaft 605 is restricted after passing through the inner guide groove 21 of the guide frame 2, and it can only move in a straight line above the photovoltaic panel 15. Therefore, the heated cleaning roller 601 will move back and forth in contact with the surface of the photovoltaic panel 15. During the process, the hot air in the micropores 602 will melt the snow on the surface, and the bristles 603 on the surface of the cleaning roller 601 have the effect of cleaning the snow, avoiding the problem that too much snow accumulates, which not only blocks the sunlight and affects the power conversion efficiency of the photovoltaic panel 15, but also causes continuous damage to the photovoltaic panel 15. The two connecting shafts 605 in the cleaning roller 601 are connected by a molybdenum rod 606 to form a whole, which improves the mechanical strength and stability of the connecting shaft 605. The molybdenum rod 606 has good high temperature resistance and low cost of use, can effectively resist the heat emitted by the high-resistance heating wire 607 and will not increase the cost of the device too much.

[0034] Embodiment 2: Figure 1-Figure 3 As shown, support rods 12 are installed on the outer surfaces of both sides of the support shell 14 near the corners, and the length of the front support rod 12 is smaller than that of the rear support rod 12. A socket 11 is sleeved on the bottom end of the support rod 12. A waist-shaped groove for installing a first bolt 13 is opened on the outer surface of the socket 11, and the first bolt 13 passes through the support rod 12 to fix the socket 11 and the support rod 12 together. A base frame 1 is fixedly connected between the bottoms of the four sockets 11.

[0035] In this embodiment, when in use, the support shell 14 is mainly used to install and support the photovoltaic panel 15, and the base frame 1 and the support rod 12 are mainly used to support the device off the ground. The socket 11 and the support rod 12 are plugged in and fixed with the first bolt 13, and a waist-round groove is provided at the position corresponding to the first bolt 13, so the height of the support rod 12 can be adjusted within a small range before tightening.

[0036] Embodiment 3: Figure 1 , Figure 2 , Figure 4 , Figure 6 and Fig. 9 As shown, there are two groups of self-rotating mechanisms 4, and each group of self-rotating mechanisms 4 is composed of a connecting plate 401, a rack 402 and a compound gear 403. The connecting plate 401 is fixedly connected to the top of the support shell 14 and is located on the inner side of the two guide frames 2. The rack 402 is fixedly installed on the outer surface of the connecting plate 401 with the teeth facing upward. The compound gear 403 is fixedly installed at the end of the cleaning roller 601 and is located on the outer side of the second bearing 604. The outer surface of the compound gear 403 is meshed with the top of the rack 402.

[0037] In this embodiment, when in use, the cleaning roller 601 is rotatably connected to the connecting shaft 605 through the second bearing 604, so the cleaning roller 601 can rotate on the surface of the connecting shaft 605 during the linear movement of the connecting shaft 605, and the composite gear 403 installed at the end of the cleaning roller 601 is meshed with the surface of the rack 402 fixed to the support shell 14 through the connecting plate 401. Therefore, when the cleaning roller 601 moves following the connecting shaft 605, under the action of the rack 402 and the composite gear 403, the cleaning roller 601 will be driven to rotate continuously, so the cleaning roller 601 will move and rotate at the same time, at this time, the micropores 602 close to the surface of the photovoltaic panel 15 will alternate continuously, so that the micropores 602 that emit hot air will quickly move away after approaching the photovoltaic panel 15 to transfer heat, so as to avoid the low temperature from entering the cleaning roller 601 through the micropores 602 and affecting the temperature of the cleaning roller 601, and the rotating cleaning roller 601 can effectively improve the cleaning effect of the bristles 603, and the design structure is simple and does not require an additional power source to further improve the snow cleaning effect.

[0038] Embodiment 4: Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, the sliding mechanism 5 includes a mounting block 501, which is rectangular and has the top and bottom portions near the corners protruding outward, and the inner surface walls of the mounting block 501 are rotatably connected to the positions near the four corners, and the outer surface of the rotating shaft 502 is rotatably connected to the roller 503, and the mounting block 501 is fixedly connected to the outer surface of the connecting shaft 605 and is located inside the guide groove 21, and the outer surface of the roller 503 is rollingly fitted with the inner surface wall of the guide groove 21.

[0039] In this embodiment, when in use, when the guide frame 2 limits the connecting shaft 605 through the guide groove 21, the mounting block 501 installed on the surface of the connecting shaft 605 and located inside the guide groove 21 will slide synchronously in the guide groove 21, and when the mounting block 501 slides in the guide groove 21, the roller 503 connected to its inner wall by the rotating shaft 502 will roll against the inner wall of the guide groove 21. This method converts the sliding friction between the connecting shaft 605 and the guide groove 21 into rolling friction, greatly reducing the friction force and friction damage, and improving the stability of the cleaning component 6 when moving on the surface of the photovoltaic panel 15. The design has a simple structure and practical functions, and effectively improves the stability and reliability of the device when in use.

[0040] The effect and working principle of the whole mechanism are as follows: when the distributed photovoltaic power generation device is used in areas with frequent snowfall and snow accumulates on the surface, after the high-resistance heating wire 607 is powered by an external power supply, the high-resistance heating wire 607 will convert the electrical energy into thermal energy and play the role of heating the cleaning roller 601, and part of the hot air will be discharged through the micropores 602 to heat the surface of the photovoltaic panel 15, thereby promoting the melting of ice and snow. During the process, the dual-axis motor 16 at the bottom of the supporting shell 14 is started and the driving pulleys 19 on both sides are driven to rotate through the two driving shafts 18. At this time, under the action of friction, the belt 304 on the surface of the driving pulley 19 will move around the surface of the driving pulley 19 and the guide pulley 307. The belt 304 is fixedly connected by the clamp block 301 and the connecting shaft 605 extending outward from the inside of the cleaning roller 601, so a drag force is generated on the connecting shaft 605 and the cleaning roller 601. After the connecting shaft 605 passes through the inner guide groove 21 of the guide frame 2, its moving path is restricted and it can only move in a straight line above the photovoltaic panel 15. Therefore, the heated cleaning roller 601 will move back and forth along the surface of the photovoltaic panel 15. During the process, the hot air in the micropores 602 will melt the snow on the surface, and the bristles 603 on the surface of the cleaning roller 601 have the effect of cleaning the snow, thereby avoiding the problem that the accumulation of too much snow not only blocks the sunlight and affects the power conversion efficiency of the photovoltaic panel 15, but also causes continuous damage to the photovoltaic panel 15.

[0041] At the same time, the cleaning roller 601 is rotatably connected to the connecting shaft 605 through the second bearing 604, so the cleaning roller 601 can rotate on the surface of the connecting shaft 605 during the linear movement of the connecting shaft 605, and the composite gear 403 installed at the end of the cleaning roller 601 is meshed with the surface of the rack 402 fixed to the support shell 14 through the connecting plate 401. Therefore, when the cleaning roller 601 moves following the connecting shaft 605, under the action of the rack 402 and the composite gear 403, the cleaning roller 601 will be driven to rotate continuously, so the cleaning roller 601 will move and rotate at the same time. At this time, the micropores 602 close to the surface of the photovoltaic panel 15 will alternate continuously, so that the micropores 602 that emit hot air will quickly move away after approaching the photovoltaic panel 15 to transfer heat, so as to avoid low temperature from entering the cleaning roller 601 through the micropores 602 and affecting the temperature of the cleaning roller 601, and the rotating cleaning roller 601 can effectively improve the cleaning effect of the bristles 603. The design structure is simple and does not require an additional power source to further improve the snow cleaning effect.

[0042] When the guide frame 2 limits the connecting shaft 605 through the guide groove 21, the mounting block 501 installed on the surface of the connecting shaft 605 and located inside the guide groove 21 will slide synchronously in the guide groove 21. When the mounting block 501 slides in the guide groove 21, the roller 503 connected to its inner wall by the rotating shaft 502 will roll against the inner wall of the guide groove 21. This method converts the sliding friction between the connecting shaft 605 and the guide groove 21 into rolling friction, greatly reducing the friction force and friction damage, and improving the stability of the cleaning component 6 when moving on the surface of the photovoltaic panel 15. The design has a simple structure and practical functions, and effectively improves the stability and reliability of the device during use.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
