Description

Technical Field

[0001] The utility model relates to the technical field of subsurface wetlands, and more specifically to an anti-clogging water distribution device for artificial wetlands. Background Art

[0002] Artificial wetlands are swamp-like surfaces that are artificially constructed and controlled. Sewage and sludge are distributed in a controlled manner on the artificially constructed wetlands. In the process of sewage and sludge flowing in a certain direction, the technology mainly utilizes the physical, chemical and biological synergistic effects of soil, artificial media, plants and microorganisms to treat sewage and sludge.

[0003] After searching, the utility model patent with announcement number CN218778805U discloses an anti-clogging water distribution device for artificial wetlands, including a water distribution pipe, the upper middle end of the water distribution pipe is connected with a perforated pipe through a tee, the upper outer curved surface of the perforated pipe is penetrated with a water outlet hole, the upper outer curved surface of the perforated pipe is penetrated with a mounting groove, the lower outer end of the mounting groove is fixedly connected with a slide box, the bottom of the slide box is fixedly connected with a spring, the upper end of the spring is fixedly connected with a slider plate, pin holes are penetrated on both sides of the upper end of the slide box, pins are inserted into the inner wall of the pin hole, the outer curved surface of the top of the perforated pipe is rotatably connected with a protective cover, and the inner bottom surface of the protective cover is fixedly connected with a rotating guide plate; this patent inserts the pin into the inner wall of the pin hole again to keep the slider plate locked and fixed, thereby playing the role of selectively blocking the water outlet hole through the slider plate, thereby realizing the role of selectively adjusting the water distribution flow rate of sewage treatment.

[0004] However, the above patents still have the following shortcomings: the protection of the absorption port by the protective cover is limited, and debris can easily enter the absorption port from the side of the protective cover, affecting the absorption of the absorption port. At the same time, due to the existence of the protective cover, it is not convenient to adjust the slider plate inside the absorption port; in addition, it is not convenient to filter impurities in the water to prevent the water outlet from being blocked. For this reason, we propose an artificial wetland anti-blocking water distribution device. Utility Model Content
