DETAILED DESCRIPTION

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 2 and 3 As shown, this embodiment discloses a roof drainage and floor drain anti-blocking device, including a water collecting pipe 1, a hat-shaped bracket 2, a flexible annular baffle 3 and an impeller 4.

[0023] The hat-shaped bracket 2 is located at the top of the water collecting pipe 1. The hat-shaped bracket 2 mainly includes a top plate 201. Four support rods 202 are arranged in a ring around the top plate 201. The upper ends of the support rods 202 are fixedly connected to the top plate 201, and the lower ends are fixedly connected to the annular bottom plate 203. The annular bottom plate 203 is arranged on the top of the water collecting pipe 1. In this embodiment, the hat-shaped bracket 2 is semicircular.

[0024] The flexible annular blocking net 3 can be made of nylon net. The main function of the flexible annular blocking net 3 is to block debris such as leaves. The flexible annular blocking net 3 is arranged on the inner side of the hat-shaped bracket 2. The upper annular edge of the flexible annular blocking net 3 is fixedly connected to the top plate 201, and the lower annular edge of the flexible annular blocking net 3 is connected to the annular bottom plate 203. The upper and lower annular edges of the flexible annular blocking net 3 can be pressed on the top plate 201 and the annular bottom plate 203 by a pressure ring, and the pressure ring is fixed to the top plate 201 and the annular bottom plate 203 by bolts. In this embodiment, the flexible annular blocking net 3 is a truncated cone with a small upper opening and a large lower opening.

[0025] The impeller 4 is arranged in the water collecting pipe 1, and a wheel shaft 5 is fixed on the top of the impeller 4, and the wheel shaft 5 is rotatably connected to the top plate 201. A connecting disk 6 is fixed on the wheel shaft 5, and a plurality of extension rods 7 are arranged in a ring shape around the connecting disk 6. One end of the extension rod 7 is fixed to the connecting disk 6, and a ball 8 is fixed to the other end. The ball 8 is in contact with the flexible annular baffle 3.

[0026] When in use, the water collecting pipe 1 is connected to the drainage pipe pre-buried in the roof, and rainwater flows to the water collecting pipe 1 through the mesh of the flexible annular baffle net 3, while leaves and other debris are blocked by the flexible annular baffle net 3. The rainwater washes the impeller 4 to rotate, and the impeller 4 is driven by the wheel shaft 5 to rotate the connecting plate 6. During the rotation of the connecting plate 6, the ball 8 connected to it is constantly in contact with the flexible annular baffle net 3. The ball 8 pushes the flexible annular baffle net 3 outward at the position in contact with the flexible annular baffle net 3, thereby causing the debris attached to the outside of the flexible annular baffle net 3 to fall off. At the same time, the ball 8 causes the flexible annular baffle net 3 to bulge outward at the position in contact with the flexible annular baffle net 3, thereby expanding the gap between the debris on the outside of the baffle net, allowing rainwater to pass smoothly.

[0027] like Figure 4 As shown, in this embodiment, the water collecting pipe 1 includes a pipe body 101, the top of the pipe body 101 is flared, and an annular outer edge 102 is arranged on the top of the pipe body 101, an annular rib 103 is arranged on the top of the annular outer edge 102, and the annular bottom plate 203 is located in the annular rib 103.

[0028] In this embodiment, a plurality of annularly arranged auxiliary struts 9 are provided on the inner side of the annular bottom plate 203 , one end of the auxiliary struts 9 is fixed to the annular bottom plate 203 , and the other end is fixed to the connecting sleeve 10 , and the connecting sleeve 10 is rotatably connected to the wheel axle 5 .

[0029] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
