[0002] In order to ensure the long-term use of the roof and the overall safety of the building, it is crucial to install an effective roof drainage system. Existing roofs are generally in a herringbone shape, with drainage channels around the roof. Rainwater flows into the drainage channels along the sloping roof. Downpipes are installed in the drainage channels, and the rainwater flowing into the drainage channels is discharged from the downpipes.

[0003] Some existing drainage channels are directly constructed with concrete during the house construction process. The drainage channels are arranged in a U-shape and surround the roof. Downspouts are installed on the bottom of the drainage channels. The structural strength of such drainage channels is high and the drainage channels have a certain width, so that people can walk into the drainage channels to clean up garbage and ensure the patency of the drainage channels. However, the drainage channels are relatively long and the bottom surface of the drainage channels is relatively rough, which causes garbage to easily accumulate at various locations on the bottom surface of the drainage channels, making cleaning more troublesome.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a roof drainage structure.

[0009] The utility model is further configured as follows: the left and right ends of the permeable net are fixedly connected to the inner side of the wall by expansion bolts.

[0010] The utility model is further configured as follows: the four diversion slopes are two high diversion slopes and two low diversion slopes, the maximum height of the high diversion slope is greater than the maximum height of the low diversion slope, and the low diversion slope is arranged in the diversion area on the left and right sides of the roof.

[0011] The utility model is further configured as follows: two height-increasing walls are provided on the top surface of the enclosure wall, and the two height-increasing walls are respectively located on the left and right sides of the roof.

[0012] In summary, the utility model has the following beneficial effects: the middle part of the diversion slope is high and the two sides are low, so that rainwater can flow along the diversion slope to the drainage area after falling into the diversion area, and the stainless steel plate is arranged on the top surface of the diversion slope, so that the diversion slope is relatively smooth, and the garbage falling into the diversion area can be moved toward the drainage area under the drive of rainwater, so that the garbage will be concentrated in the four drainage areas and is not easy to stay in the diversion area.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] A roof drainage structure, such as Figure 1As shown, it includes a house body 1 and a roof 2, a gable-shaped top slope 3 is provided on the roof 2, and the top slope 3 is inclined to the left and right sides of the roof 2, and a wall 4 surrounding the roof 2 is provided on the house body 1, and a drainage channel is formed between the wall 4 and the roof 2, and the drainage channel includes four drainage areas 5 and four diversion areas 6. The four drainage areas 5 are respectively arranged near the four corners of the house body 1, and two adjacent drainage areas 5 are connected through the diversion area 6. The bottom surface of the diversion area 6 is cast to form a diversion slope. The closer the height of the diversion slope is to the drainage area 5 at both ends, the lower it is. A stainless steel plate 7 is fixedly connected to the top surface of the diversion slope. The middle part of the diversion slope is high and the two sides are low, so that rainwater can flow along the diversion slope to the drainage area 5 after falling into the diversion area 6. The stainless steel plate 7 is arranged on the top surface of the diversion slope. , making the diversion slope smoother, the garbage falling into the diversion area 6 can be moved towards the drainage area 5 under the drive of rainwater, and then the garbage will be concentrated in the four drainage areas 5, and it is not easy to stay in the diversion area 6. In this way, people only need to clean the garbage in the drainage area 5 to clean most of the garbage in the drainage channel, ensuring the patency of the drainage channel. The above arrangement reduces the area where people need to clean the drainage channel and reduces the time required for people to clean. The drainage area 5 is square and the diversion area 6 is long. The side length of the drainage area 5 is at least twice the width of the diversion area 6. A downpipe 8 is installed on the bottom surface of the drainage area 5. The area of ​​the drainage area 5 is large, so that the space available for people to move is also relatively large, which is convenient for people to carry out cleaning operations and also improves the capacity of the drainage channel to accommodate garbage.

[0019] like Figure 1As shown, the downpipe 8 is arranged near a corner of the drainage area 5, and a permeable net 9 is installed in the drainage area 5. The fence 4 and the permeable net 9 together surround the water inlet of the downpipe 8. The permeable net 9 can block the garbage in the drainage area 5 from the water inlet of the downpipe 8, so that the garbage is not easy to fall into the downpipe 8. An intersection area is provided in the drainage area 5, and the intersection area is located at the intersection of the two diversion areas 6. The positions of the downpipe 8 and the permeable net 9 in the drainage area 5 avoid the intersection area. The instantaneous speed of rainwater located in the diversion area 6 entering the drainage area 5 is relatively fast. The permeable net 9 avoids the interaction area, which can reduce the impact of rainwater on the permeable net 9, thereby ensuring the life of the permeable net 9. The permeable net 9 is not in the two diversion areas 6 The extended position in the length direction requires the water flow to rebound once after passing through the wall 4 before entering the permeable net 9, which greatly reduces the impact force on the permeable net 9. The left and right ends of the permeable net 9 are fixed to the inner side of the wall 4 by expansion bolts. The permeable net 9 is fixed by the expansion bolts. After people drive the expansion bolts into the wall 4, the expansion bolts pass through the permeable net 9, and then fix the permeable net 9 with nuts threaded on the expansion bolts. This arrangement ensures the fixing strength of the permeable net 9, and makes it possible for people to disassemble the permeable net 9 by unscrewing the nuts, which is convenient for people to replace the permeable net 9. The downpipe 8 is located in the corner of the drainage area 5, which reduces the area required for the permeable net 9.

[0020] like Figure 2 and Figure 3 As shown, the four diversion slopes are two high diversion slopes 10 and two low diversion slopes 11. The maximum height of the high diversion slope 10 is greater than the maximum height of the low diversion slope 11. The low diversion slope 11 is set in the diversion area 6 on the left and right sides of the roof 2. The high diversion slope 10 is located in the diversion area 6 on the front and back sides of the roof 2. The top slope 3 guides most of the rainwater into the diversion area 6 on the left and right sides of the roof 2. Therefore, the amount of rainwater is large, which makes the rainwater have a strong ability to drive garbage. Therefore, the maximum height of the diversion slope does not need to be too large, and the amount of rainwater falling into the diversion area 6 on the front and back sides of the roof 2 is relatively small. Therefore, by ensuring the maximum height of the diversion slope The height is increased to ensure the diversion effect of rainwater, improve the ability of rainwater to carry garbage, and reduce the retention of garbage. Two heightening walls 12 are set on the top surface of the wall 4. The two heightening walls 12 are respectively located on the left and right sides of the roof 2. When the rainfall is heavy, the rainwater flowing out from the left and right sides of the roof 2 will be accelerated by the top slope 3, so that the rainwater can easily flush out of the drainage ditch. The heightening walls 12 on the left and right sides of the roof 2 can ensure that the rainwater can smoothly flow into the diversion area 6, and the rainwater flowing out from the front and back sides of the roof 2 is hardly accelerated by the top slope 3, so that the rainwater is not easy to flush out of the drainage ditch. Therefore, there is no need to increase the height of the wall 4.

[0021] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
