DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] See also Figure 1-8 In an embodiment of the present invention, a solar green building with a water-saving function comprises a building roof 1 and a fixing plate 2 fixedly mounted on the building roof 1 and symmetrically arranged, a water guide plate 3 is fixed on the fixing plate 2, and a water guide groove 4 is provided on the water guide plate 3, characterized in that the solar green building with a water-saving function also includes:

[0032] See also Figure 1-3 , Figure 5-7 The photovoltaic panel 5 is fixed on the water guide plate 3, wherein the water guide plate 3 is arranged in an inclined shape, and a filter hole is opened on the side of the water guide groove 4 facing the building roof 1, so that the cleaned water can be filtered and recycled.

[0033] A support plate 16 is arranged above the photovoltaic panel 5. A cleaning mechanism is arranged on the support plate 16. The cleaning mechanism includes a cleaning component and a cleaning roller 26. The cleaning component can drive the cleaning roller 26 to roll on the photovoltaic panel 5. The cleaning component includes a hollow rod 23 fixedly mounted on the support plate 16. A movable rod 24 is movably mounted in the hollow rod 23. A No. 2 spring 25 fixedly connected to the movable rod 24 is fixed in the hollow rod 23. The movable rod 24 is rotatably connected to the cleaning roller 26.

[0034] It should be noted that, since the photovoltaic panel 5 is exposed to the air, a lot of dust will stick to its surface after long-term use, which reduces the working efficiency of the photovoltaic panel 5. Therefore, the photovoltaic panel 5 needs to be cleaned. In the initial state, the No. 2 spring 25 is in a normal state. At this time, the movable rod 24 is located at the end of the stroke away from the hollow rod 23, and the cleaning roller 26 is located below the surface of the photovoltaic panel 5. When the photovoltaic panel 5 needs to be cleaned, the support plate 16 moves along the length direction of the photovoltaic panel 5 and drives the cleaning roller 26 to move. When the cleaning roller 26 abuts against the surface of the photovoltaic panel 5, under the action of the photovoltaic panel 5, the cleaning roller 26 moves to the surface of the photovoltaic panel 5 and drives the movable rod 24 to move toward the hollow rod 23, so that the No. 2 spring 25 is compressed. Under the action of the No. 2 spring 25, it is ensured that the cleaning roller 26 is in close contact with the photovoltaic panel 5, thereby cleaning the photovoltaic panel 5.

[0035] See also Figure 1-3 , Figure 5-7 The support plate 16 is also provided with a spraying mechanism, and the spraying mechanism includes a spraying assembly and a nozzle 32. The spraying mechanism can cooperate with the photovoltaic panel 5 and transport water to the photovoltaic panel 5 through the nozzle 32. The spraying assembly includes a water storage box 27 fixedly mounted on the support plate 16, and a fixed sleeve 28 is fixed on the water storage box 27. A discharge structure connected to the fixed sleeve 28 is provided on the water storage box 27, and a pulley 33 symmetrically arranged is rotatably mounted on the discharge structure. The water storage box 27 is connected to the pumping assembly, wherein the discharge structure includes a discharge pipe 29 movably mounted in the fixed sleeve 28 and passing through the water storage box 27, a receiving plate 31 is fixed on the discharge pipe 29, and a No. 3 spring 30 abutting against the discharge pipe 29 is fixed in the water storage box 27, the receiving plate 31 is rotatably connected to the pulley 33, and a discharge trough is provided on the discharge pipe 29.

[0036] Furthermore, a sealing gasket is fixed on the discharge pipe 29. In the initial state, the third spring 30 is in a compressed state, so that the discharge pipe 29 is located at the end of the stroke in the direction of the water guide plate 3. At this time, the sealing gasket is tightly fitted with the bottom of the water storage box 27, and the discharge trough is located outside the water storage box 27 to ensure that the water in the water storage box 27 will not be discharged. When the photovoltaic panel 5 needs to be cleaned, the support plate 16 moves, driving the pulley 33 to move. When the pulley 33 moves to abut against the surface of the photovoltaic panel 5, the receiving plate 31 is driven to move toward the water storage box 27, and the discharge pipe 29 is driven to move, so that the sealing gasket and When the bottom of the water storage box 27 is separated, the discharge pipe 29 will also drive the discharge trough to move and enter the water storage box 27. At this time, the water in the water storage box 27 will enter the discharge pipe 29 through the discharge trough and be discharged to the photovoltaic panel 5 through the nozzle 32. After the water is sprayed, the photovoltaic panel 5 is cleaned under the action of the cleaning roller 26. When the pulley 33 is separated from the photovoltaic panel 5, the No. 3 spring 30 is elastically released and drives the discharge pipe 29 to move away from the water storage box 27, so that the sealing gasket fits with the bottom of the water storage box 27 again, and the water in the water storage box 27 cannot be discharged, thereby achieving the effect of automatic water discharge.

[0037] See also Figure 1-3 , a moving mechanism is arranged on the fixed plate 2 and fixedly connected to the support plate 16. The moving mechanism can drive the cleaning mechanism and the spraying mechanism to move through the support plate 16. The moving mechanism includes a No. 1 screw rod 6 rotatably mounted on the fixed plate 2, and a No. 1 threaded sleeve 7 that is threadedly matched with the No. 1 screw rod 6 is movably mounted on the No. 1 screw rod 6. A guide assembly connected to the No. 1 threaded sleeve 7 is provided on the fixed plate 2, and a card slot 9 is opened on the guide assembly. The guide assembly is fixedly connected to the support plate 16 and connected to the adjustment mechanism, wherein the guide assembly includes a guide rod 11 fixedly mounted on the fixed plate 2, and a guide sleeve 10 is movably mounted on the guide rod 11. The guide sleeve 1 0 is fixed with a connecting plate 8 fixedly connected to the No. 1 threaded sleeve 7, the connecting plate 8 is provided with the slot 9 and is provided with a transverse movement structure connected to the adjusting mechanism, the transverse movement structure is fixedly connected to the support plate 16, the transverse movement structure mentioned above includes a motor 12 fixedly mounted on the connecting plate 8, a No. 2 screw rod 13 connected to the output shaft of the motor 12 is rotatably mounted on the connecting plate 8, a No. 2 threaded sleeve 14 threadably matched with the No. 2 screw rod 13 is movably mounted on the No. 2 screw rod 13, a rotating rod 15 engaged with the slot 9 is rotatably mounted on the No. 2 threaded sleeve 14, a limiting rod is fixed on the rotating rod 15 and is connected to the adjusting mechanism, and the rotating rod 15 is fixedly connected to the support plate 16.

[0038] Furthermore, since the photovoltaic panel 5 is set at an angle, in order to ensure a better cleaning effect of the photovoltaic panel 5, it is necessary to drive the cleaning roller 26 and the nozzle 32 so that the top of the photovoltaic panel 5 is cleaned in the horizontal direction, and the casting moves toward the bottom of the photovoltaic panel 5. When the photovoltaic panel 5 needs to be cleaned, the motor 12 works at this time and drives the No. 2 screw rod 13 to rotate, thereby driving the No. 2 threaded sleeve 14 to move. The No. 2 threaded sleeve 14 will drive the rotating rod 15 to move along the length direction of the slot 9. Since the rotating rod 15 is engaged with the slot 9, it is ensured that the No. 2 threaded sleeve 14 moves along the length direction of the No. 2 screw rod 13 and will not rotate with the No. 2 screw rod 13. The rotating rod 15 will also drive the support plate 16 to move, thereby driving the cleaning roller 26 and the nozzle 32 to move, so as to clean the photovoltaic panel 5. The panel 5 is cleaned. When the No. 2 threaded sleeve 14 moves to the end of the stroke, another position of the photovoltaic panel 5 needs to be cleaned. At this time, the No. 1 screw 6 rotates, driving the No. 1 threaded sleeve 7 to move, thereby driving the connecting plate 8 to move. The connecting plate 8 will also drive the guide sleeve 10 to move along the length direction of the guide rod 11. The guide rod 11 has a guiding function, so that the No. 1 threaded sleeve 7 moves along the length direction of the No. 1 screw 6 and will not rotate with the No. 1 screw 6. When the cleaning roller 26 and the nozzle 32 move to another position of the photovoltaic panel 5, the No. 1 screw 6 stops rotating, and the motor 12 drives the No. 2 screw 13 to rotate in the opposite direction, so that the cleaning roller 26 moves toward the other direction of the No. 2 screw 13, and repeats the above steps to achieve cleaning of the photovoltaic panel 5.

[0039] See also Figure 1-3 , Figure 5-6 , Figure 8 The fixed plate 2 is also provided with an adjusting mechanism connected with the moving mechanism, and the adjusting mechanism can drive the support plate 16 to rotate through the moving mechanism. The adjusting mechanism includes a movable sleeve 17 movably mounted on the rotating rod 15, and the rotating rod 15 is sleeved with a No. 1 spring 20 abutting against the movable sleeve 17. A limit plate 19 is fixed on the movable sleeve 17, and a gearing assembly connected with the limit plate 19 and the movable sleeve 17 is provided on the connecting plate 8, wherein the gearing assembly includes a limit plate 21 and a rack plate 22 fixedly mounted on the connecting plate 8 and symmetrically arranged, a gear 18 intermittently meshed with the rack plate 22 is fixed on the movable sleeve 17, and the limit plate 21 is intermittently matched with the limit plate 19.

[0040] Furthermore, the limit plate 19 is set in a cone shape. In order to ensure the cleaning effect, the photovoltaic panel 5 needs to be sprayed with water before cleaning. Therefore, it is necessary to ensure that the nozzle 32 is always located in front of the cleaning roller 26 along its movement direction. In the initial state, the gear 18 and the rack plate 22 are in a separated state, and the limit plate 19 and the limit plate 21 are in a separated state. When the nozzle 32 and the cleaning roller 26 are separated from the photovoltaic panel 5, the limit plate 19 and the inclined surface of the limit plate 21 abut against each other, so that the limit plate 19 moves in the direction away from the support plate 16, thereby driving the movable sleeve 17 to move, so that the gear 18 moves, and the No. 1 spring 20 is stretched. When the limit plate 19 moves to abut against the plane of the limit plate 21, the gear 18 just moves to the same height as the rack plate 22 and meshes with the rack plate 22. Under the action of the rack plate 22, the gear The wheel 18 rotates, and due to the engagement of the limit rod and the limit groove, the rotating rod 15 is driven to rotate through the movable sleeve 17, thereby driving the support plate 16 to rotate. When the gear 18 is separated from the rack plate 22, the nozzle 32 and the cleaning roller 26 rotate half a circle, thereby changing the position of the nozzle 32 and the cleaning roller 26. At this time, the limit plate 19 is separated from the limit plate 21, and the No. 1 spring 20 elastically contracts, so that the limit plate 19 moves to the bottom of the limit plate 21. At this time, the No. 2 threaded sleeve 14 moves in the other direction. When the limit plate 19 moves to abut against the other side of the inclined section of the limit plate 21, the limit plate 19 is driven to move toward the support plate 16 and compress the No. 1 spring 20 to ensure that the gear 18 is separated from the rack plate 22, and the position of the nozzle 32 and the cleaning roller 26 will not change. Repeat the above steps to fully clean the photovoltaic panel 5.

[0041] See also Figure 1-2 A pumping assembly is arranged on the roof 1 of the building and connected to the spraying mechanism. The pumping assembly can transport the filtered water to the spraying mechanism. The pumping assembly includes a water tank 34 fixedly installed on the roof 1 of the building. A water pump 35 is fixed on the water tank 34. The water pump 35 is connected to a conduit 36 ​​connected to the water storage box 27.

[0042] Finally, under the action of the cleaning roller 26, the cleaned water is pushed into the water guide plate 3 and enters the water guide groove 4. Under the action of the filter holes, the water is filtered and flows back into the water tank 34. When the photovoltaic panel 5 needs to be cleaned, the water pump 35 works and transports water to the water storage box 27 through the conduit 36.

[0043] Taking the embodiment combining all the features recorded in the present application as an example, when in use, since the photovoltaic panel 5 is exposed to the air, a lot of dust will stick to its surface after long-term use, which reduces the working efficiency of the photovoltaic panel 5. Therefore, the photovoltaic panel 5 needs to be cleaned, the water pump 35 works, and transports water to the water storage box 27 through the conduit 36. At the same time, the motor 12 works and drives the No. 2 screw rod 13 to rotate, thereby driving the No. 2 threaded sleeve 14 to move. The No. 2 threaded sleeve 14 will drive the rotating rod 15 to move along the length direction of the slot 9. Since the rotating rod 15 is engaged with the slot 9, it is ensured that the No. 2 threaded sleeve 14 moves along the length direction of the No. 2 screw rod 13 and will not rotate with the No. 2 screw rod 13. The rotating rod 15 will also drive the support plate 1 6 moves, thereby driving the cleaning roller 26 and the nozzle 32 to move. When the pulley 33 moves to abut against the surface of the photovoltaic panel 5, the receiving plate 31 is driven to move toward the water storage box 27, and the discharge pipe 29 is driven to move, so that the sealing gasket is separated from the bottom of the water storage box 27. The discharge pipe 29 will also drive the discharge chute to move and enter the water storage box 27. At this time, the water in the water storage box 27 will enter the discharge pipe 29 through the discharge chute and be discharged to the photovoltaic panel 5 through the nozzle 32. When the cleaning roller 26 abuts against the surface of the photovoltaic panel 5, under the action of the photovoltaic panel 5, the cleaning roller 26 moves to the surface of the photovoltaic panel 5. Under the action of the cleaning roller 26, the photovoltaic panel 5 is cleaned. When the nozzle 32 and the cleaning roller 26 are separated from the photovoltaic panel 5, the limit plate 19 abuts against the inclined surface of the limit plate 21, so that the limit plate 19 moves in the direction away from the support plate 16, thereby driving the movable sleeve 17 to move, so that the gear 18 moves, and the No. 1 spring 20 is stretched. When the limit plate 19 moves to abut against the plane of the limit plate 21, the gear 18 just moves to the same height as the rack plate 22 and meshes with the rack plate 22. Under the action of the rack plate 22, the gear 18 rotates. Due to the engagement of the limit rod and the limit groove, the rotating rod 15 is driven to rotate through the movable sleeve 17, thereby driving the support plate 16 to rotate. When the gear 18 is separated from the rack plate 22, the nozzle 32 and the cleaning roller 26 rotate half a circle, thereby changing the position of the nozzle 32 and the cleaning roller 26. At this time, the limit plate 19 and the limit groove are engaged. The plate 21 is separated, and the No. 1 spring 20 elastically contracts, so that the limit plate 19 moves to the bottom of the limit plate 21. At this time, the No. 1 screw 6 rotates, driving the No. 1 threaded sleeve 7 to move, thereby driving the connecting plate 8 to move. The connecting plate 8 will also drive the guide sleeve 10 to move along the length direction of the guide rod 11. The guide rod 11 has a guiding function, so that the No. 1 threaded sleeve 7 moves along the length direction of the No. 1 screw 6 and will not rotate with the No. 1 screw 6. When the cleaning roller 26 and the nozzle 32 move to another position of the photovoltaic panel 5, the No. 1 screw 6 stops rotating, and the motor 12 drives the No. 2 screw 13 to rotate in the opposite direction, so that the cleaning roller 26 moves toward the other direction of the No. 2 screw 13, and repeats the above steps to achieve cleaning of the photovoltaic panel 5.

[0044] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
