Smart Gate System Device (Zhangmenren)
Background
In combined sewer systems, stormwater, sewage and surface water are not fully separated. Large volumes of rainwater and other fresh water enter interception pipes and dilute sewage concentration, while uncontrolled overflow outlets allow sewage to escape. Installing an intelligent control device upstream of the trunk sewer - or at the overflow outlet - is therefore essential.
Operating Principle
An electrically driven device that cuts off water flow in drainage applications. It is typically installed on interception pipes and overflow pipes of interception wells, on storage tank inlets and at river outfalls. A hoist raises and lowers the gate to control interception, and the opening/closing position determines how stormwater and sewage are managed. Used together with baffles, screens or bar racks that capture coarse and suspended solids, it improves influent concentration at treatment plants and protects natural water bodies.
Smart gates also regulate flow and water level: in urban drainage they adjust to rainfall to discharge standing water quickly and avoid flooding; in irrigation they control flow precisely to crop demand; in river flood control they close in time to hold back floodwater and protect surrounding areas.
Product Advantages
- Small footprint - wall-mounted, compact structure, greatly reduced land use
- Short build time - highly integrated, modular installation, minimal civil works
- More reliable - real-time monitoring, bidirectional discharge, low energy consumption and easy maintenance
- Good flow capacity - second-level response, opening area no smaller than the outfall, no reduction of the flow cross-section
- Professional customisation - configurations tailored to owner requirements for flood control, storage and replenishment, water exchange and black-odorous water treatment
- High automation - digital control via the intelligent O&M platform for condition-based operation
- Unattended operation - remote monitoring through the platform reduces management effort and cost
