The flexible water-blocking cloth and the inner bottom surface of the annular water tank 103 are spaced apart, so that the leaves and other impurities adhered to the coarse filter screen 104 can pass through the gap between the flexible water-blocking cloth and the annular water tank 103 when the annular water tank 103 rotates, so that the leaves and other impurities are rotated to a position convenient for cleaning.

[0029] As a preferred embodiment in the present embodiment, it needs to be further explained that one side of the vertical water guide pipe 2 is provided with an outwardly protruding arc-shaped sealing cavity 4, as shown in Figure 3 In practice, the arc-shaped sealing cavity 4 can be provided with an opening on one side of the vertical water guide pipe 2, and a semicircular cover is sealingly installed at the opening, so that the cover forms an arc-shaped sealing cavity 4 on one side of the vertical water guide pipe 2. The waterwheel 5 is rotatably connected in the arc-shaped sealing cavity 4, and the waterwheel 5 includes a central shaft and water wheels uniformly distributed on the central shaft. The water wheels of the waterwheel 5 near the opening on one side of the vertical water guide pipe 2 extend into the vertical water guide pipe 2, so that the rainwater flowing downward in the vertical water guide pipe 2 can impact on the water wheels, and the waterwheel 5 is driven to rotate by the impact of the water flow in the vertical water guide pipe 2 on the water wheels. The central shaft of the waterwheel 5 penetrates to the outside of the arc-shaped sealing cavity 4 and is coaxially connected with the fan blade 6. The fan blade 6 can rotate with the waterwheel 5 when the waterwheel 5 rotates. In this way, the owner of the house can observe the rotation of the fan blade 6 to understand the flow of rainwater in the vertical water guide pipe 2, and the fan blade 6 can also be used as an ornamental object. Alternatively, the fan blade 6 is aligned with the door and window, and in hot summer, the fan blade 6 can blow wind into the room, improving the overall practicability.

[0030] As a preferred embodiment in the embodiment, it needs to be explained further that the arc-shaped sealing cavity 4 is externally provided with a gear box, the central shaft of the waterwheel 5 penetrates through the gear box and is rotationally matched with the gear box, the first bevel gear 7 and the second bevel gear 8 are arranged in the gear box and are mutually meshed, so that the first bevel gear 7 and the second bevel gear 8 can synchronously rotate, the first bevel gear 7 is coaxially arranged on the central shaft of the waterwheel 5, when the waterwheel 5 rotates, the first bevel gear 7 can be driven to rotate by the central shaft, then the second bevel gear 8 is driven to rotate by the first bevel gear 7, the second bevel gear 8 is coaxially connected with a transmission shaft 9, the second bevel gear 8 can drive the transmission shaft 9 to rotate, the middle part of the transmission shaft 9 is rotationally connected with the gear box, so as to ensure the stability and flexibility of the transmission shaft 9, the lower end of the transmission shaft 9 is connected with a small gear 10, the upper part of the upper rotating barrel 102 is coaxially connected with a large gear 11, the small gear 10 is meshed with the large gear 11, the transmission shaft 9 can drive the small gear 10 to rotate, the small gear 10 drives the large gear 11 to rotate, the large gear 11 drives the upper rotating barrel 102 to rotate, so as to realize the rotation adjustment of the annular water tank, in this way, the annular water tank can be slowly driven to rotate in the process of rainwater flowing down, so as to avoid that the impurities such as leaves are all gathered on the coarse filter screen 104 below the vertical water guide pipe 2, and ensure the smooth filtration of rainwater. It needs to be explained that the number of teeth of the edge meshing teeth of the small gear 10 is less than the number of teeth of the edge meshing teeth of the large gear 11 in the embodiment, so that a deceleration effect can be realized, and then the waterwheel 5 can still drive the annular water tank to slowly rotate when rotating at high speed, and rainwater will not be splashed because the annular water tank rotates too fast.

[0031] As a preferred embodiment in the embodiment, it needs to be explained further that the large gear 11 is coaxially connected with a first rotating shaft, the lower part of the first rotating shaft is connected with the middle part of the upper rotating barrel 102, so that the large gear 11 can drive the upper rotating barrel 102 to rotate through the first rotating shaft when the large gear 11 rotates, and then the rotation of the annular water tank is realized.

[0032] As a preferred implementation scheme in this embodiment, it needs to be further explained that the lower part of the first rotating shaft is connected to the middle part of the upper rotating barrel 102 through the first one-way bearing 12, and the middle part of the upper rotating barrel 102 is provided with a first mounting groove, the outer ring of the first one-way bearing 12 is connected to the inner wall of the first mounting groove, and the inner ring of the first one-way bearing 12 is connected to the first rotating shaft, so as to realize the connection between the first rotating shaft and the upper rotating barrel 102. In practice, for example, when the waterwheel 5 rotates and drives the large gear 11 to rotate forward, the large gear 11 drives the first rotating shaft to rotate, and the first rotating shaft drives the first one-way bearing 12 to rotate forward. The inner and outer rings of the bearing 12 rotate together, and then the outer ring of the first one-way bearing 12 drives the upper rotating barrel 102 to rotate forward. When the water wheel 5 cannot rotate due to poor rainwater circulation (this situation may be that too many leaves, etc. rise in the annular water trough and block the lower end of the vertical water pipe 2), the upper rotating barrel 102 can also be controlled by hand to rotate in the opposite direction. The reverse rotation of the upper rotating barrel 102 will not be affected by the presence of the first one-way bearing 12, which can reduce the force applied when manually controlling the upper rotating barrel 102 to rotate, making manual control easier.

[0033] As a preferred implementation scheme in this embodiment, it needs to be further explained that a second mounting groove is provided in the middle of the upper end of the lower fixed barrel 101, and a central boss is provided at the lower end of the middle of the upper rotating barrel 102. The central boss is rotatably connected to the second mounting groove through a ball bearing 109, so that the upper rotating barrel 102 can be rotated more easily relative to the lower fixed barrel 101.

[0034] As a preferred implementation scheme in this embodiment, it needs to be further explained that arc-shaped sealing covers are connected to both sides of the lower end of the vertical water pipe 2, and the two arc-shaped sealing covers are matched to the upper end of the annular water trough 103, and the two arc-shaped sealing covers are slidably matched with the upper end of the annular water trough 103, thereby better preventing rainwater from splashing during the downstream process, and the two arc-shaped sealing covers are spaced apart from one end of the vertical water pipe 2 and cooperate with the annular water trough 103 to form a water trough opening, which is convenient for cleaning impurities such as leaves at the water trough opening.

[0035] As a preferred implementation scheme in this embodiment, it needs to be further explained that the vertical water conduit 2 is externally connected with a sealing cover connecting ring, both sides of which extend downward and are connected to the two arc-shaped sealing covers, which facilitates the installation of the arc-shaped sealing covers and also facilitates later disassembly; the sealing cover connecting ring includes two correspondingly arranged semicircular clamps, the two sides of which are connected by bolts and clamped to the outside of the vertical water conduit 2. By tightening the bolts, the two semicircular clamps hold the vertical water conduit 2 tightly, thereby achieving relative fixation of the sealing cover connecting ring and the arc-shaped sealing cover, thereby making the rotation of the upper rotating barrel 102 easier.

[0036] Finally, it should be noted that the above description is only preferred embodiments of the present application and is not intended to limit the scope of protection of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of protection of the present application.
