Description

Technical Field

[0001] The utility model relates to the technical field of urban rainwater recycling, in particular to an urban rainwater collecting and filtering device. Background Art

[0002] Rainwater carries natural impurities such as leaves, branches, dust, gravel, sand, etc. during its descent.

In order to maintain the normal operation of the rainwater collection system, it is necessary to regularly clean the clogged leaves and impurities, which increases labor and maintenance costs. The clearing work is time-consuming, which will affect the efficiency of rainwater recovery to a certain extent. Utility Model Content

[0038] Working principle: When in use, the collected rainwater enters the main pipe 2 from the water inlet 3, and impurities such as leaves in the rainwater will be intercepted by the filter tank 8. When some of the larger impurities such as leaves will roll down from the rotating bucket 7 into the movable collection bin 4, the other part will adhere to the rotating bucket 7. When there are too many impurities on the rotating bucket 7 and affect the flow of rainwater, the servo motor 13 is started, and the output shaft of the servo motor 13 drives the wheel 14 to rotate. When the wheel 14 rotates, it can drive the movement and rotation of the connecting rod 15. At the same time, the other end of the connecting rod 15 drives the butterfly gear plate 1 through the fixed column 12 1 continuously rotates back and forth. When the butterfly gear plate 11 rotates back and forth, it meshes with the two gears 9 in the two slag discharge and filtering components, so that the gear 9 can drive the rotating bucket 7 on the fixed shaft 6 to rotate. At this time, the two rotating buckets 7 rotate relative to each other.
