[0037] It can be understood that the drainage bucket 1 is movably connected to the drainage pipe 2. At the same time, the drainage bucket 1 and the drainage pipe 2 are made of the same material, PVC. The filter plate 3 and the barrier plate 4 are preferably made of stainless steel. When installing the filter plate 3, the filter plate 3 is rotatably connected to the drainage bucket 1 so that the filter plate 3 can rotate.

[0038] The rooftop drainage device for house construction provided by the embodiment of the present invention comprises a filter plate 3 and a baffle plate 4. A first filter hole 301 and a second filter hole 401 are respectively provided on the filter plate 3 and the baffle plate 4. Moreover, the size of the first filter hole 301 is smaller than the size of the second filter hole 401, thereby enabling better secondary filtration of rainwater. Secondly, the filter plate 3 is arranged to be rotatable so that when too many leaves are accumulated on the filter plate 3, the filter plate 3 can be pressed to rotate, so that the accumulation of too many leaves will not affect the drainage effect, thereby enabling the water flow to be unobstructed even in heavy rain, thereby better improving the drainage effect and reducing the blockage caused by leaves.

[0039] According to the roof drainage device for house construction provided by an embodiment of the utility model, a connecting groove 302 is opened inside the filter plate 3, a rotating shaft 303 is rotatably embedded in the connecting groove 302, and a rotating groove 101 is opened on the inner wall of the drainage bucket 1, and both ends of the rotating shaft 303 are rotatably embedded in the rotating groove 101 respectively.

[0040] Figure 5 、 Figure 6 and Figure 7 A roof drainage device for building construction is implemented in the present invention. A connecting groove 302 is opened through the inside of the filter plate 3, and a rotating shaft 303 is rotatably embedded in the connecting groove 302. In addition, a rotating groove 101 is opened on the inner wall of the drainage bucket 1, and the two ends of the rotating shaft 303 are rotatably embedded in the rotating groove 101, so that the rotating shaft 303 can be easily rotated, making the filter plate 3 more flexible.

[0041] The roof drainage device for house construction provided by the embodiment of the present invention can better embed the rotating shaft 303 through the provided connecting groove 302, and at the same time enable the filter plate 3 to rotate under the action of the rotating shaft 303, and at the same time better place the filter plate 3 in the drainage bucket 1 through the rotating shaft 303, and the rotating groove 101 is provided on the inner wall of the drainage bucket 1, so that the rotating shaft 303 can be installed more conveniently, and secondly, it is convenient for the rotating shaft 303 to rotate, thereby improving the drainage effect.

[0042] According to the rooftop drainage device for house construction provided by the embodiment of the utility model, the upper surface of the filter plate 3 is inclined, and a buffer structure is fixedly provided along the inclined end at the bottom of the filter plate 3, and the buffer structure is fixedly connected to the inner wall of the drainage bucket 1.

The tilted surface of the filter plate 3 is tilted downward, and the buffer structure is correspondingly provided at the bottom of the tilted end of the filter plate 3.

[0044] The rooftop drainage device for house construction provided by the embodiment of the present invention provides an inclined structure for the filter plate 3 so that the filter plate 3 can better gather the filtered impurities and leaves to one end during filtering, so that the filter plate 3 will not be blocked as a whole and will not affect the drainage effect of the filter plate 3. By providing a buffer structure at the bottom of the upper inclined end corresponding to the filter plate 3, when more leaves and impurities accumulate at the other end, the upper inclined end of the filter plate 3 can be better pressed up, and a drain gap will appear at the same time, thereby allowing rainwater to flow down better. The provided buffer structure better limits the drain gap from being too large when formed and affecting the filtering effect.

[0045] According to the roof drainage device for house construction provided by the embodiment of the utility model, the buffer structure includes a connecting plate 5 and a tension spring 501.

One end of the tension spring 501 is fixedly connected to the connection plate 5, and the other end is fixedly connected to the filter plate 3. At the same time, two tension springs 501 are preferably provided so that the force is more uniform during stretching.

[0047] The roof drainage device for house construction provided by the embodiment of the present invention better limits the range of movement of the inclined end of the filter plate 3 by means of the provided connecting plate 5 and the tension spring 501, thereby avoiding the situation where the inclined end of the filter plate 3 is opened too much and the filtering effect is poor, while not affecting the drainage effect, thereby preventing drainage and filtration from interfering with each other, thereby improving the overall effect, and at the same time setting the connecting plate 5 to a semi-arc structure will not affect the drainage.

At the same time, the baffle plate 4 is preferably set to a circular ring structure, and the second filter holes 401 are distributed in a circular array along the edge of the baffle plate 4, so that the second filter holes 401 are arranged more evenly.

[0053] The rooftop drainage device for house construction provided by the embodiment of the present invention has a second filter hole 401 set up, and the baffle plate 4 is set to a circular ring structure, so that the edge of the drainage bucket 1 can be better wrapped by the baffle plate 4, so that the baffle plate 4 performs a first filter on the rainwater, and then filters and separates some larger leaves and impurities, thereby reducing the blockage of the filter plate 3, so that the rainwater can be better discharged, and the overall drainage effect is improved.
