AI Technical Summary

Technical Problem

Traditional rainwater chains are prone to splashing outwards due to wind or gravitational acceleration during use, resulting in slippery ground and damp surrounding walls. Furthermore, the scattered rainwater droplets make it difficult to collect and reuse the water, and may erode the foundation or damage green facilities, especially during heavy rain.

Method used

The design combines a lotus-shaped outer liner, an inner liner tube, a hollowed-out shape, and an inner liner base. The curved shape of the lotus-shaped outer liner forms a natural barrier, and the connection structure between the inner liner tube and the inner liner base enables the directional guidance of rainwater and the suppression of splashing. The design of the connecting chain and mounting holes ensures the stability of the structure and convenient installation.

Benefits of technology

It effectively reduces water splashing, enhances the aesthetics and stability of the rain chain, ensures smooth rainwater guidance, prevents water accumulation and detachment, and strengthens the durability and applicability of the structure.

Abstract

This utility model relates to the field of rainwater chain technology, and in particular to a non-splashing rainwater chain structure, including a lotus-shaped outer liner, an inner liner cylinder inside the lotus-shaped outer liner, a first mounting hole, a second mounting hole and a hollow design on the outer surface of the inner liner cylinder, a first connecting strip at the top of the inner liner cylinder, a first connecting chain inside the first connecting strip, and an inner substrate seat at the bottom of the lotus-shaped outer liner. The bottom of the inner liner cylinder is fixedly connected to the inner substrate seat. By using the lotus-shaped outer liner, the inner liner cylinder, the hollow design and the inner substrate seat in combination, the directional guidance of rainwater and the suppression of splashing are achieved. The bottom of the inner liner cylinder is connected to the inner substrate seat, and the inner liner cylinder is located inside the lotus-shaped outer liner. The hollow design ensures the structural strength while increasing the permeability of rainwater, avoiding the increase in pressure caused by water accumulation, and has aesthetic appeal and reduces the overall weight. The inner substrate seat plays a stable supporting role, ensuring the stability and durability of the entire rainwater chain structure.
