GW-GC-R Remote‑controlled Intelligent Gate Hoist

1. Product Overview

This set of intelligent actuation‑retrofit equipment is specially designed for the intelligent upgrade of existing old sluice gates. It adopts a sluice‑body‑free retrofit solution: the original gate leaf, gate frame, civil foundation and water‑sealing structure of the user are fully reused. There is no need to dismantle or replace the sluice body. Only by adding a DC intelligent actuator, supporting IoT intelligent sluice‑gate controller, and stand‑alone solar power‑supply system, traditional old gates operated by manual hand‑crank or simple electric control can be upgraded into fully‑automatic, remotely‑accessible, auto‑measuring‑and‑controlling intelligent irrigation water‑control devices.

Inheriting mature IoT measurement‑control technologies from Gewu Zhicheng, the equipment is suitable for high‑standard farmland construction, canal‑irrigation informatization, and intelligent‑retrofit projects for small‑scale water conservancy works. It effectively addresses industry pain points of traditional sluice gates: time‑consuming & labor‑intensive manual opening/closing, high operation‑and‑maintenance costs, severe water‑resource waste, absence of data monitoring, and lack of remote control capabilities. Through lightweight and low‑cost retrofitting, it realizes digitalized, refined and unattended management for farmland water conservancy and canal water control, facilitating agricultural water‑saving & efficiency improvement and digital transformation of water conservancy.

• Ultra‑low‑power Drive: Equipped with high‑performance industrial DC low‑power motor; gate opening‑closing speed＞4 mm/s with smooth & efficient actuation and extremely low standby power consumption. Balances operating efficiency and long‑term energy‑saving performance for round‑the‑clock low‑power on‑duty scenarios.

2.3 Highly‑reliable Durable Protection Design

• Reliable Equipment Materials: Control cabinet adopts spray‑painted galvanized sheet‑metal; transmission accessories are made of stainless steel for corrosion resistance and aging resistance, adapting to complex outdoor environments such as extreme cold, high temperature, saline‑alkali and humid conditions.
• Multiple Intelligent Protections: Multi‑layer protections including motor overload & stall protection, over‑charge / over‑discharge protection, short‑circuit protection, lightning‑protection grounding, water‑proof & dust‑proof features, effectively avoiding equipment damage, water‑leakage jamming and circuit failures to guarantee long‑term stable equipment operation.

2.4 Precise Monitoring & Intelligent Data Management

• Sensor Expansion Adaptation: Optional accessories such as electronic water‑level gauge, radar water‑level gauge and flow meter can be deployed to collect core data including upstream‑and‑downstream water levels and irrigation flow in real‑time, providing accurate data support for smart irrigation and water‑conservancy dispatching.
• Full‑dimension Data O&M: Automatically stores equipment operation data, gate open‑close records, water‑level variation data and battery‑voltage data. Supports historical‑data query & export. Alarm notifications will be pushed for low‑battery, equipment fault and network anomaly conditions, greatly reducing manual operation‑and‑maintenance costs.
