[0002] At present, drainage equipment refers to the collection, transportation, water quality treatment and discharge of drainage facilities in a certain way. It is a general term for drainage pipes and buildings at all levels for waterlogging, waterlogging and salt prevention. The existing roof drainage methods are divided into organized drainage and unorganized drainage, among which organized drainage is the most widely used. That is, rainwater on the roof is discharged to the outdoor ground or underground ditch in an organized manner through the drainage system.

[0003] The existing roof anti-blocking drainage device is easily loaded when encountering heavy rainfall, resulting in poor drainage effect. At the same time, when there are impurities such as sludge in the water flow, it is easy to clog the filter, which will reduce the drainage efficiency of the drain pipe and cause water accumulation on the roof.

[0004] Therefore, there is a need for a building roof anti-blocking drainage device to solve the problems of poor drainage effect and easy clogging of the filter screen by sludge impurities in the prior art. Utility Model Content

[0007] The transmission mechanism can drive the mounting rod to rotate when the fan blades rotate, and further drive the active bevel gear to rotate, thereby driving the driven bevel gear to rotate, thereby achieving a transmission effect.

[0008] It should be noted in the scheme that the transmission mechanism includes a rotating groove, which is opened on the inner wall of the protective member, and the inner wall of the rotating groove is rotatably mounted with a driving bevel gear and a driven bevel gear, one end of the driving bevel gear is fixed with a mounting rod, one end of the mounting rod is fixed with a fan blade, and a rotating rod is fixed at the center of the bottom end of the driven bevel gear.

[0009] It is further worth noting that the driving bevel gear and the driven bevel gear are meshingly connected.

[0010] It should be further explained that a filter screen is fixed to the outer wall of the rotating rod, and the outer wall of the filter screen is movably connected to limit pulleys at four corners.

[0011] As a preferred embodiment, brush plates are fixed to both ends of the inner wall of the funnel, and the brush plates are in contact with the filter screen.

[0012] A plurality of limiting pulleys are movably installed on the outer wall of the filter screen, and are limited and movable on the inner wall of the limiting slide groove, thereby driving the filter screen to perform limited rotation, so that the drainage efficiency can be improved.

[0013] As a preferred implementation manner, the bottom end of the rotating rod is rotatably mounted on the surface of the positioning plate.

[0014] As a preferred implementation, the limiting pulley is movably mounted on the inner wall of the limiting sliding groove.

[0015] Through the transmission mechanism, when the fan blades rotate, it can drive the mounting rod to rotate, and further drive the active bevel gear to rotate, thereby driving the driven bevel gear to rotate, thereby achieving a transmission effect. When the driven bevel gear rotates, it can drive the rotating rod to rotate, thereby driving the filter to rotate. When the filter rotates, it can drive the drainage inside the funnel to rotate, thereby improving the drainage effect.

[0016] Compared with the prior art, the utility model provides a building roof anti-blocking drainage device, which has at least the following beneficial effects:

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with embodiments.

[0025] See also Figure 1-4 The utility model provides a building roof anti-blocking drainage device, including a roof 1, a funnel 2 is arranged at the top drainage of the roof 1, a limiting slide groove 9 is arranged on the inner wall of the funnel 2, a drainage pipe 3 is fixed to the bottom end of the funnel 2, a positioning plate 12 is fixed to the inner wall of the drainage pipe 3, positioning frames 4 are fixed on both sides of the funnel 2, connecting rods 5 are fixed on the opposite side of the positioning frames 4, and a protective member 6 is fixed to the other end of the connecting rod 5, and a transmission mechanism 7 is arranged on the inner wall of the protective member 6.

[0026] The transmission mechanism 7 can drive the mounting rod 73 to rotate when the fan blade 74 rotates, and further drive the active bevel gear 72 to rotate, thereby driving the driven bevel gear 75 to rotate, thereby achieving a transmission effect.

[0027] Further as Figure 1 , Figure 2 As shown, it is worth specifically explaining that the transmission mechanism 7 includes a rotating groove 71, and the rotating groove 71 is opened on the inner wall of the protective member 6. The inner wall of the rotating groove 71 is rotatably mounted with a driving bevel gear 72 and a driven bevel gear 75, respectively. A mounting rod 73 is fixed to one end of the driving bevel gear 72, and a fan blade 74 is fixed to one end of the mounting rod 73. A rotating rod 76 is fixed at the center of the bottom end of the driven bevel gear 75.

[0028] When the roof 1 needs to be drained, when the external wind is strong on a rainy day, it can drive the fan blades 74 to rotate, and then drive the active bevel gear 72 to rotate, and further drive the driven bevel gear 75 to rotate, thereby driving the rotating rod 76 to rotate, and when the rotating rod 76 rotates, it can drive the filter 11 to rotate, so that when it rotates, it drives rainwater to rotate, thereby improving the drainage effect.

[0029] Further Figure 2 As shown, it is worth to explain in detail that the driving bevel gear 72 and the driven bevel gear 75 are meshingly connected.

[0030] This solution has the following working process: when it is necessary to drain the surface of the roof 1, the external wind force is strong due to thunderstorm weather, thereby driving the fan blades 74 to rotate, and further driving the mounting rod 73 to rotate, thereby enabling the active bevel gear 72 to rotate, and then driving the driven bevel gear 75 to rotate, further driving the rotating rod 76 to rotate, thereby driving the filter 11 to rotate.
