Description

Technical Field

[0001] The present application relates to the technical field of drainage devices, and in particular to a drainage device for a building roof. Background Art

[0002] The roof drainage device of a building is a device used to remove water from the roof. From ancient times to the present, the drainage of the building roof has always been an issue that has been given special consideration in architectural design. The roofs of ancient buildings mostly adopt a high ridge and a large slope design, using the steep slope to make rainwater flow down rapidly, and then using inertia to let the rainwater flow out of the eaves. The accumulated water is directly discharged from the roof to the ground, causing water accumulation on the ground. Rainwater falls from the roof, causing inconvenience when people pass under the eaves. In the existing design, a drainage channel is designed under the eaves, and the accumulated water in the drainage channel is removed through a drainage pipe to solve the drainage problems of some existing building roofs.

[0003] For example, patent No. (CN201820896623.5) is a building roof drainage device, including a drainage structure, a drainage channel and a drainage pipe, characterized in that: the top of the drainage structure is fixedly connected to the drainage channel by bolts, the bottom end of the drainage structure is embedded with a drainage pipe, and the front end of the drainage pipe is embedded with a fixing ring; the top of the drainage channel is fixedly connected to the filter by bolts, a limited flow trough is welded at the inner bottom end of the drainage channel, and an inclined channel bottom is welded at the bottom end of the drainage channel; the fixing includes a cast iron layer, a rubber block and fixing bolts, a cast iron layer is welded inside the fixing ring, the right side of the fixing ring is fixedly connected to rubber by bolts, and fixing bolts are embedded at both the upper and lower ends of the fixing ring.

[0004] In the above structure, since obstructions such as leaves and branches often fall from the roof, the obstructions are transported to the filter with the water flow, which causes the filter to be blocked by the obstructions, and the obstructions need to be cleaned frequently; therefore, it is necessary to design a building roof drainage device that is easy to clean.

[0049] The drainage channel 1 is fixedly arranged on the wall 107; Figure 4 , a plurality of fixing members 106 are fixedly provided on the wall surface 107 by screws; a semicircular arc surface 108 corresponding to the bottom surface of the semicircular tube 101 is formed on the fixing member 106, the semicircular tube 101 is arranged on the arc surface 108, and the fixing member 106 is fixedly connected to the semicircular tube 101 by screws;

[0050] The drainage channel 1 is fixed under the eaves by a fixing member 106 to receive rainwater sliding down from the eaves. The rainwater flows from the drainage port 103 on the drainage channel 1 into the water receiving pipe 105, and then flows along the drainage pipe 104 to the sewer, thereby preventing the rainwater on the eaves from falling directly on the ground in front of the house.

[0051] The building roof drainage device also includes: a filter element 2, a fixing frame 201, a rack 203, a driving element 204, and a gear 208;

[0052] The filter element 2 is provided to filter out obstructions such as fallen leaves and branches on the roof to prevent the obstructions from clogging the water pipe; the drive element 204, the rack 203 and the gear 208 are provided to drive the filter element 2 to flip and dump out the obstructions to prevent the obstructions from clogging the filter element 2. It is no longer necessary to manually climb to the roof to clean the obstructions, thereby achieving more convenient cleaning of the obstructions;

[0053] refer to Figure 2 The filter element 2 is rotatably disposed on the drain channel 1 in a semicircular sheet shape, and the filter element 2 is fitted with the inner wall of the circumference of the drain channel 1 and covers the drain outlet 103; a plurality of drain holes 212 are formed on the filter element 2 at positions corresponding to the drain outlet 103, so that the accumulated water flows from the drain channel 1 into the water receiving pipe 105;

[0054] Two connecting members 210 are fixedly arranged on the side of the drain channel 1 away from the wall 107, and a rotating shaft 207 is fixedly arranged on the side of the filter element 2 close to the connecting member 210.
