The baffle 41 is arranged in a semicircular shape, so that the outside impurities can flow to the side, away from the water inlet 51, of the interception piece 52 along with rainwater, and the possibility that the water inlet 51 is blocked due to the fact that larger impurities enter the water inlet 51 is further reduced.

The implementation principle of the rainwater collection device for the building construction is as follows: when the rainfall is less, rainwater converges between the second floating plate 7 and the concave sealing cover 5, so that the second floating plate 7 drives the floating plug 6 to move, and the rainwater flows into the rainwater collection tank 1 through the water inlet 51 for storage. At this time, when the amount of rainwater stored in the rainwater collecting tank 1 is excessive, the first floating plate 17 is caused to act by the floating force generated by the rainwater, and the first floating plate 17 drives the filter screen 16, the connecting piece 22, the adjusting piece 21 and the limiting plate 23 to move in a direction away from the settling plate 13 in sequence, so that the adjusting piece 21 blocks the settling tank 131. Meanwhile, the first rack 231 drives the gear 32 to rotate, and the gear 32 drives the plugging plate 31 to move through the second rack 312, so that the sewage draining groove 311 is communicated with the water draining port 12, and the rainwater in the sewage collecting cavity 14 can drive deposited impurities to flow out of the rainwater collecting tank 1. And along with the outflow of rainwater, the regulating piece 21 and the limiting plate 23 move to the direction close to the inner bottom of the rainwater collecting tank 1, so that the regulating piece 21 and the sedimentation tank 131 form a platform hole again.

When the rainfall is enough, external rainwater continuously flows into the rainwater collection tank 1 from the water inlet 51, so that the first floating plate 17 drives the filter screen 16, the connecting piece 22, the adjusting piece 21 and the limiting plate 23 to move in a direction away from the sedimentation plate 13, and the adjusting piece 21 is used for blocking the sedimentation tank 131. At this time, the rainwater in the dirt collecting chamber 14 drives the deposited impurities to flow out of the rainwater collecting tank 1. And then the adjusting piece 21 is separated from the settling tank 131, so that rainwater in the water storage cavity 15 flows into the dirt collecting cavity 14 through the settling tank 131 and washes the guide surface 19, thereby being convenient for cleaning the dirt collecting cavity 14.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
