TECHNICAL FIELD
[0001] The utility model relates to the field of building drainage, more specifically, it relates to a roof drainage structure. BACKGROUND
[0002] The houses with flat roofs generally set some drainage structures on the top to drain the accumulated water on the roof, and the most common drainage mode is to set a drainage flow channel, to collect the accumulated water in the flow channel through the difference in horizontal height, and then to guide the accumulated water into a specific drainage port through the flow channel, and the drainage port is generally provided with a corresponding pipeline for transmitting the accumulated water to a specific area for drainage or treatment, however, the accumulated water often contains dirt, and the dirt is wrapped by the water flow and finally gathered into the pipeline system through the drainage port, which can easily cause the drainage port or the pipeline system to be blocked. SUMMARY
[0003] In view of the deficiencies in the prior art, the utility model aims to provide a roof drainage structure.
[0004] The above technical purpose of the utility model is realized by the following technical scheme: a roof drainage structure, comprising a flow channel, wherein an inner side wall of the flow channel is in the form of a circular arc surface, another inner side wall of the flow channel is in the form of an inclined surface tangent to the circular arc surface, a plurality of partition plates are arranged in the flow channel at intervals, the partition plates are detachably connected with the inner side walls of the flow channel, and the top surface of the partition plates is lower than the highest water level of the flow channel.
[0005] The utility model is further provided as follows: the top surface of the partition plate is not higher than one half of the highest water level of the flow channel.
[0006] The utility model is further provided as follows: the partition plate is fixedly connected with a connecting rod, and the connecting rod connects all the partition plates.
[0007] The utility model is further provided as follows: the bottom surface of the connecting rod is fixedly connected with the top surface of the partition plate.
[0008] The utility model is further provided as follows: the two connecting rods are distributed on both sides of the top end of the flow channel.
[0009] The utility model is further provided as follows: a plurality of overflow grooves are formed in the connecting rod, and the overflow grooves are located between adjacent partition plates.
[0010] In summary, the utility model has the following beneficial effects: the partition plates intercept the deposited sundries in the cavities, reduce the sundries gathered to the drainage port, avoid the sundries from blocking the drainage port, the partition plates can be taken out when cleaning is needed, the partition plates do not hinder the cleaning, the cross-sectional area of the partition plate is smaller than that of the flow channel, when there are more sundries in a single cavity, the deposited sundries can be transferred to the adjacent cavity through the partition plate, and the flow channel is prevented from being blocked due to too much sundries in a single cavity.

[0014] The utility model will be described in detail below in combination with the drawings and examples.
[0015] Example: a roof drainage structure, as shown in Figure 1 、 Figure 2 , including flow passage 1, the inner side wall of flow passage 1 is circular arc surface, the other inner side wall of flow passage 1 is the inclined plane that is tangent to circular arc surface, a plurality of partition 2 are arranged at intervals in flow passage 1, and partition 2 is detachably connected with the inner side wall of flow passage 1, the top surface of partition 2 is lower than the highest water level of flow passage 1, and the top surface of partition 2 is not higher than one half of the highest water level of flow passage 1.
[0016] Specifically, flow passage 1 is provided with a drainage port at one end, and the cross section of flow passage 1 is composed of a quarter circle and a quarter rhombus, which is convenient for sweeping out the sundries in flow passage 1 when the sundries move in the gravity flow passage 1 through the relatively gentle inclined surface, the outer contour of partition 2 is attached to the contour of the side wall of flow passage 1, and partition 2 divides flow passage 1 into multiple chambers, when the sundries move along with the water flow, partition 2 intercepts the deposited sundries in the chamber, reduces the sundries converging to the drainage port, avoids the sundries from blocking the drainage port, when cleaning is needed, partition 2 is taken out, which avoids that partition 2 hinders cleaning, and the cross-sectional area of partition 2 is relatively small compared to the cross-sectional area of flow passage 1, when there are more sundries in a single chamber, the deposited sundries will be transferred to the adjacent chamber by crossing partition 2, avoiding that the sundries in a single chamber are too much to cause flow passage 1 to be blocked.
[0017] As shown in Figure 1 、 Figure 2 , partition 2 is fixedly connected with connecting rod 3, connecting rod 3 connects all partition 2, the bottom surface of connecting rod 3 is fixedly connected with the top surface of partition 2, two connecting rods 3 are distributed on both sides of the top end of flow passage 1, a plurality of overflow grooves 4 are formed in connecting rod 3, and the overflow grooves 4 are located between adjacent partition 2.
