Latest Patents

One of his latest patents is a "System for treating and recycling rainwater." This system includes at least three stages of constructed wetlands arranged along a sloped surface. Each constructed wetland consists of a coarse gravel layer, a fine gravel layer, an improved soil layer, and wetland plants from bottom to top. The design features slopes on both sides of the upper part of each wetland, differing in height. An intermediate overflow pipe is positioned at the top of the slope between adjacent wetlands, while a final overflow pipe connects to a municipal rainwater system. The coarse gravel layers of adjacent wetlands are interconnected by pipes, and a perforated water collecting pipe is placed at the front ends of these connecting pipes. Additionally, a water outlet pipe is located at the bottom of the last stage's coarse gravel layer, linking to a clean water reservoir.

Another significant patent is the "Method for roof drainage," aimed at reducing urban waterlogging. This method involves installing a drainage device on a roof, which includes a drainage exit and a drainage pipe. The drainage exit is elevated between 5 and 10 cm above the roof. A water outlet hole is positioned on the drainage pipe's wall at the same height as the roof or lower. A siphon is incorporated into the drainage pipe, with its inlet facing the roof and the outlet extending into the pipe. Furthermore, a ball cock mechanism is installed on the drainage wall to control the opening and closing of the water outlet hole.
