Most of the collected rainwater is stored in collection wells. In order to facilitate the collection of rainwater, most of them are equipped with water inlets, and then a cover is placed on the water inlet.

[0003] A Chinese patent discloses a rainwater collection and filtration manhole cover (CN209538234U), comprising a circular manhole cover with an annular groove on its sidewall; the bottom surface of the annular groove is tilted downward; a plurality of through-holes extend downward from the bottom surface of the annular groove; filter cotton is disposed within the annular groove, and activated carbon is disposed within the through-holes. A rainwater collection tray is disposed at the bottom of the manhole cover. The filter cotton disposed within the annular groove concealed in the sidewall effectively filters large particles of impurities in the water, which are then removed by the activated carbon disposed within the through-holes to remove odors and flow into the rainwater collection tray for further utilization. Current covers have fixed water inlet sizes and are easily clogged by impurities in the rainwater, thereby reducing the amount of rainwater entering. Therefore, a non-clogging cover for rainwater collection wells is provided. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the current cover plate is easily blocked, and to propose an anti-blocking cover plate for a rainwater collection well.

During the rising process of the lifting rack, the threaded rod rotates under the action of the transmission gear. As the threaded rod rotates, the threaded sleeve moves under the action of the thread. At this time, the threaded sleeve drives the movable plate to move through the connecting rod. When the movable plate moves, it cleans the impurities filtered down from the filter screen. According to the amount of water, the impurities around the cover plate are automatically cleaned, which effectively prevents the cover plate from being blocked and further improves the collection efficiency of the rainwater collection well.

[0019] 2. In the present invention, an expansion component is provided and the cover body is installed at the water inlet of the rainwater collection well. When the amount of rainwater is small, it will be discharged into the collection well through the drainage groove between the float plate and the cover body, and the filter screen will clean the impurities in the rainwater. When the rainfall is heavy, as the rainwater at the cover body increases, the float plate will rise under the buoyancy of the rainwater, thereby driving the filter screen to rise in the receiving groove under the action of the limit plate. The impurities in the rainwater are filtered by the filter screen outside the collection well. The size of the water inlet is automatically adjusted according to the amount of rainwater, thereby effectively improving the water inlet efficiency of the collection well.

[0029] The specific implementation method is as follows: as the floating plate 31 rises, the lifting rack 46 will be driven to slide on the outer surface of the fixed rod 5. During the rising process of the lifting rack 46, the threaded rod 44 rotates under the action of the transmission gear 45. As the threaded rod 44 rotates, the threaded sleeve 43 moves under the action of the thread. At this time, the threaded sleeve 43 drives the movable plate 41 to move through the connecting rod 42. When the movable plate 41 moves, it will clean the impurities filtered out of the filter screen 32.

When the rainfall is heavy, as the rainwater at the cover body 1 increases, the float plate 31 will rise under the buoyancy of the rainwater, thereby driving the filter screen 32 to rise in the receiving groove 33 under the action of the limit plate 35, and the impurities in the rainwater are filtered by the filter screen 32 outside the collection well.

[0032] Working principle: The cover body 1 is installed at the water inlet of the rainwater collection well. When the amount of rainwater is small, it will be discharged into the collection well through the drainage trough between the floating plate 31 and the cover body 1, and the filter screen 32 will clean the impurities in the rainwater. When the rainfall is heavy, as the rainwater at the cover body 1 increases, the floating plate 31 will rise under the buoyancy of the rainwater, thereby driving the filter screen 32 to rise in the storage groove 33 under the action of the limit plate 35. The impurities in the rainwater are filtered by the filter screen 32 to the outside of the collection well. As the floating plate 31 rises, the lifting rack 46 will be driven to slide on the outer surface of the fixed rod 5. During the rising process of the lifting rack 46, the threaded rod 44 rotates under the action of the transmission gear 45. As the threaded rod 44 rotates, the threaded sleeve 43 moves under the action of the thread. At this time, the threaded sleeve 43 drives the movable plate 41 to move through the connecting rod 42. When the movable plate 41 moves, it will clean the impurities filtered out of the filter screen 32.
