[0006] The present application provides a building exterior window cleaning device using renewable energy, which adopts the following technical solution:

[0007] A building exterior window cleaning device utilizing renewable energy comprises a convex eave fixedly connected to a bay window, a collection frame fixedly connected to the convex eave, a filtering mechanism disposed on the collection frame, the filtering mechanism comprising a filter screen plate, a cover plate, a transmission member and a positioning member, the filter screen plate being slidably connected to the inner wall of the collection frame, the cover plate being rotatably connected to the collection frame, the transmission member being mounted on the filter screen plate, the transmission member being able to drive the filter screen plate to move when the cover plate rotates, the positioning member being mounted on the collection frame, and the positioning member being able to fix the filter screen plate after the filter screen plate moves;

[0008] A fixing plate is fixedly connected to the collecting frame, and a blower is installed on the fixing plate;

[0009] The collecting frame is also provided with a driving assembly for driving the cover plate to rotate.

[0010] By adopting the above technical scheme, in order to improve the stability of rainwater collection, when it rains, the driving assembly is used to drive the cover plate to rotate. After the cover plate rotates, the transmission member drives the filter screen plate to move up, and then the positioning member fixes the filter screen plate. At this time, the upper end surface of the filter screen plate is located outside the collection frame. At this time, the rainwater passes through the filter screen plate and enters the collection frame for collection. After the rainwater is collected, the blower is started to blow away the impurities and dust remaining on the filter screen plate to facilitate the next collection of rainwater. After the rainwater is collected, the driving assembly is used to rotate the cover plate. At this time, the transmission member drives the filter screen plate to move down, and finally the cover plate is used to close the collection frame to reduce the possibility of evaporation of the collected rainwater, thereby improving the stability of rainwater collection and reducing the possibility of impurities blocking the pipe in the collection tank.

[0011] Preferably, the transmission member includes a connecting rod, a fixed seat, a moving rod and a return spring, the connecting rod is fixedly connected to the filter screen, the collecting frame is provided with a makeshift groove for the connecting rod to pass through, the fixed seat is fixedly connected to the connecting rod, the fixed seat is provided with a sliding groove, the moving rod is slidably connected to the inner wall of the sliding groove, one end of the return spring is fixedly connected to the moving rod, the other end of the return spring is fixedly connected to the inner wall of the sliding groove, both ends of the moving rod are provided with inclined surfaces, and the cover plate can contact the moving rod.

[0012] By adopting the above technical solution, after the cover plate rotates, when the cover plate contacts the moving rod, the moving rod, the moving seat and the connecting rod are pushed upward, and the movement of the connecting rod drives the filter screen plate to move upward. After the positioning piece fixes the connecting rod, the cover plate continues to rotate. At this time, since the moving rod is provided with an inclined surface, the cover plate pushes the moving rod to move to the side close to the reset spring. Further, after the cover plate is separated from the moving rod, the reset spring pushes the moving rod to reset. When the cover plate rotates in the opposite direction, after the cover plate contacts the moving rod, the moving rod is pushed to move, and the movement of the moving rod drives the fixed seat and the connecting rod to move. When the connecting rod contacts the bottom wall of the give way groove, the positioning piece releases the limit of the connecting rod, and the cover plate pushes the moving rod to move, so that the moving rod moves to the side close to the reset spring. Then the cover plate continues to rotate to cover the collection frame.

[0013] Preferably, the positioning member includes a positioning rod and a limiting spring, a movable groove is provided on the inner wall of the give way groove, the positioning rod is slidably connected to the inner wall of the movable groove, one end of the limiting spring is fixedly connected to the positioning rod, and the other end of the limiting spring is fixedly connected to the inner wall of the movable groove, the end of the positioning rod is arc-shaped, and a positioning groove is provided on the connecting rod, and the positioning rod can be plugged into and matched with the positioning groove.

[0014] By adopting the above technical solution, when the positioning rod is aligned with the positioning groove, the limit spring pushes the positioning rod to move, so that the positioning rod is inserted into the positioning groove, thereby fixing the connecting rod and the filter screen plate.

[0015] Preferably, a plurality of balls are rotatably connected to the moving rod, and the cover plate can contact the balls.

[0016] By adopting the above technical solution, the friction between the cover plate and the moving rod is reduced by using the ball bearings, thereby reducing the possibility of the moving rod being damaged due to the impact of the cover plate.

[0018] By adopting the above technical solution, when the drive cover plate rotates, the drive motor is started, and the output shaft of the drive motor rotates to drive the drive gear to rotate. Since the drive gear is meshed with the driven gear, the drive gear rotates and the driven gear rotates, thereby rotating the cover plate.

[0019] Preferably, a sealing gasket is fixedly connected to the collection frame, and the cover plate is in contact with the sealing gasket.

[0020] By adopting the above technical solution and using a sealing gasket, the sealing between the collecting frame and the cover plate is improved, thereby reducing the possibility of evaporation of water in the collecting frame.

[0023] Preferably, a support bar is fixedly connected to the inner wall of the collecting frame, and the filter screen plate can be in contact with the support bar.

[0024] By adopting the above technical solution, after the filter screen plate is reset, it contacts the support bar, thereby improving the stability of the placement of the filter screen plate.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. In order to improve the stability of rainwater collection, when it rains, the driving assembly is used to drive the cover plate to rotate. After the cover plate rotates, the transmission member drives the filter screen plate to move up, and then the positioning member fixes the filter screen plate.

[0037] Reference Figure 2 and Figure 4 The transmission member 4 is installed on the filter screen plate 31. The transmission member 4 includes a connecting rod 41, a fixed seat 42, a moving rod 43 and a reset spring 44. The connecting rod 41 is fixedly connected to the filter screen plate 31. The connecting rod 41 is L-shaped. A support bar 45 is fixedly connected to the inner wall of the collection frame 2. The support bar 45 is in contact with the filter screen plate 31. The support bar 45 is used to improve the stability of the placement of the filter screen plate 31. A clearance groove 21 for the connecting rod 41 to pass through is provided on the collection frame 2. The fixed seat 42 is fixedly connected to the top end of the connecting rod 41. A sliding groove 421 is provided on the fixed seat 42. The moving rod 43 slides on the inner side wall of the sliding groove 421. One end of the reset spring 44 is fixedly connected to the moving rod 43. The reset spring 44 The other end is fixedly connected to the inner wall of the sliding groove 421. Both ends of the moving rod 43 are provided with inclined surfaces. The cover plate 32 can contact the moving rod 43. A sealing gasket 46 is fixedly connected to the collecting frame 2. The cover plate 32 contacts the sealing gasket 46. The sealing gasket 46 is used to improve the sealing between the collecting frame 2 and the cover plate 32, thereby reducing the possibility of water evaporation in the collecting frame 2. A limiting baffle 7 is fixedly connected to the collecting frame 2, and the cover plate 32 can contact the limiting baffle 7. A plurality of balls 8 are rotatably connected to the moving rod 43, and the cover plate 32 can contact the balls 8. The balls 8 are used to reduce the friction between the cover plate 32 and the moving rod 43, thereby reducing the possibility of the moving rod 43 being damaged by the impact of the cover plate 32.

[0038] The positioning member 5 is installed on the collection frame 2, and the positioning member 5 includes a positioning rod 51 and a limiting spring 52. A movable groove 22 is opened on the inner wall of the yield groove 21, and the positioning rod 51 slides on the inner wall of the movable groove 22. One end of the limiting spring 52 is fixedly connected to the positioning rod 51, and the other end of the limiting spring 52 is fixedly connected to the inner wall of the movable groove 22. The end of the positioning rod 51 is arc-shaped, and a positioning groove 411 is opened on the connecting rod 41. The positioning rod 51 can be plugged into and matched with the positioning groove 411.

[0039] Reference Figure 2 and Figure 5 The driving assembly 6 includes an extension plate 61, a driving motor 62, a driving gear 63 and a driven gear 64. The rotating shaft on the cover plate 32 passes through the rotating seat 33. The driven gear 64 is fixedly connected to the end of the rotating shaft on the cover plate 32. The extension plate 61 is fixedly connected to the outer wall of the collection frame 2. The driving motor 62 is installed on the extension plate 61. The driving gear 63 is fixedly connected to the output shaft of the driving motor 62, and the driving gear 63 is meshed with the driven gear 64.

[0040] In order to improve the stability of rainwater collection, when it rains, the driving motor 62 is started, and the output shaft of the driving motor 62 drives the driving gear 63 to rotate. Since the driving gear 63 is meshed with the driven gear 64, the driven gear 64 is driven to rotate, and the driven gear 64 is fixed on the rotating shaft of the cover plate 32. Therefore, the rotation of the driven gear 64 drives the cover plate 32 to rotate. When the cover plate 32 contacts the moving rod 43, the moving rod 43 is pushed to move upward. The movement of the moving rod 43 drives the fixed seat 42, the connecting rod 41 and the filter screen 31 to move. Afterwards, when the positioning rod 51 is in contact with the moving rod 43, the moving rod 43 is pushed upward. When the positioning grooves 411 are aligned, the limiting spring 52 pushes the positioning rod 51 to move, so that the positioning rod 51 is inserted into the positioning groove 411, so that the connecting rod 41, the filter screen plate 31 and the fixing seat 42 are fixed, and at this time the connecting rod 41 is in contact with the sealing gasket 46, and then the cover plate 32 continues to rotate. Since the moving rod 43 is provided with an inclined surface, the cover plate 32 pushes the moving rod 43 to move to the side close to the return spring 44, and then the cover plate 32 continues to rotate. When the cover plate 32 contacts the limiting baffle 7, the driving motor 62 is turned off, so that the cover plate 32 stops rotating. At this time, the cover plate 32 is in an inclined state so as to play a guiding role, so that the rainwater flows into the collection tank along the cover plate 32, thereby improving the efficiency of collecting rainwater. At the same time, the upper end surface of the filter screen plate 31 is located outside the collection frame 2. At this time, the rainwater passes through the filter screen plate 31 and enters the collection frame 2 for collection. After the rainwater is collected, the blower 35 is started to blow away the impurities and dust remaining on the filter screen plate 31, so as to collect rainwater next time. After the rainwater is collected, the drive motor 62 is started to reverse the cover plate 32. At this time, the cover plate 32 and the moving rod 43 are in a state of being collected. When in contact, the moving rod 43 is pushed downward. Since the end of the positioning rod 51 is arc-shaped, when the moving rod 43 can drive the fixing seat 42 and the connecting rod 41 to move, the positioning rod 51 moves into the moving groove 22, and the cover plate 32 continues to rotate, pushing the moving rod 43, the fixing seat 42 and the connecting rod 41 downward, thereby resetting the filter screen plate 31, and finally making the cover plate 32 contact with the sealing gasket 46, thereby reducing the possibility of evaporation of the collected rainwater, improving the stability of collecting rainwater, and reducing the possibility of impurities blocking the pipe in the collection tank.
