AI Technical Summary

Technical Problem

Existing constructed wetland water distribution devices suffer from problems such as coverage blind spots, high energy consumption, weak anti-clogging ability, and poor adaptability, making it difficult to achieve uniform water distribution and efficient purification in complex wetland environments.

Method used

It adopts a fan-shaped nozzle design that rotates without power, combined with a spiral guide channel and filter screen. It uses the kinetic energy of water to drive the nozzle to rotate, and achieves uniform water distribution and flexible adaptability through quick-release components and adjustment components. Combined with replaceable nozzles and pressure adjustment, it can adapt to different wetland scenarios.

Benefits of technology

It achieves a water distribution effect without power and self-rotation, reduces energy consumption, improves anti-clogging ability and adaptability, and ensures uniform coverage and efficient purification of the wetland system.

Abstract

This utility model relates to the field of artificial wetland water distribution technology, and discloses an artificial wetland uniform water distribution device, including a main pipe. An inlet pipe and multiple branch pipes are fixedly connected to the outer wall of the main pipe. Each branch pipe has a fan-shaped nozzle at one end, and a rotating assembly is installed on the outer wall of each fan-shaped nozzle. Each rotating assembly includes a water delivery pipe, and each water delivery pipe is located at one end of the fan-shaped nozzle. A corrugated pipe is fixedly connected to one end of each branch pipe, and a connecting pipe is fixedly connected to one end of each corrugated pipe. A fixing shell is fixedly connected to the outer wall of each connecting pipe, and a positioning ring is rotatably connected inside each fixing shell. In this utility model, the spiral guide channel utilizes the kinetic energy of the water flow to drive the nozzle rotation, achieving a self-rotating effect without power. The internal filter screen and the dynamic flushing effect formed by the rotating water flow work together to achieve efficient pre-filtration and dynamic self-cleaning.
