2. Core Functions

Multi‑mode Intelligent Control

• Remote Control: Supports WeChat Mini Program, API and PC‑based platform for real‑time monitoring and operation. Gate opening degree and open/close status can be remotely adjusted for unattended management.
• Local Electric / Manual Control: Equipped with emergency hand‑crank, screen control panel, operation buttons and BLE low‑power Bluetooth control. Manual adjustment is available upon power failure or network anomaly to guarantee continuous irrigation.
• Automatic Regulation Mode: Supports upstream‑water‑level or downstream‑water‑level linkage control (automatic adjustment according to preset water‑level values) to satisfy diversified requirements.

High‑efficiency & Energy‑saving Design

• Solar Power Supply: Combination of high‑power photovoltaic panel and large‑capacity gel battery. No external power source required; stable operation is guaranteed during successive rainy days.
• Low‑power Motor: Driven by high‑performance DC motor; gate opening‑closing speed＞4 mm/s, balancing efficiency and energy consumption.

Durability & Reliability

• Upgraded Material: Gate body and gate leaf adopt high‑strength aluminum‑alloy frame with stainless‑steel wire ropes. Excellent corrosion resistance enables operation under harsh environments such as severe cold and saline‑alkali conditions.
• Sealing & Protection: Elastic silicone sealing structure combined with multi‑layer protection design for water‑leakage prevention and anti‑jamming performance, ensuring long‑term stable operation.

Precise Monitoring & Data Management

• Optional Expansion: Integrate water‑level sensors, flow meters and other devices for real‑time collection of flow and water‑level data. Linkage with smart water‑service platform is supported to provide reference for irrigation decision‑making.
• Data Management: Supports historical‑data query and push of exception alarms (e.g. low battery, equipment fault) to improve management efficiency.

5. Installation Procedures

Pre‑installation Preparation

Technical Disclosure

1. Familiarize yourself with design drawings, installation specifications and gate technical parameters. Confirm installation position, orientation and elevation.
2. Verify gate dimension (e.g. 600×600 mm) and embedded‑part specifications against drawings.

Tools & Materials

• Tools: Electric welder, spirit level, lifting equipment (chain block, crane etc.), spanners, screwdrivers, multimeter, etc.
• Materials: Sealant, bolts, gaskets, waterproof cables, grounding wire, etc.

Foundation Inspection

1. Check position, verticality and levelness of foundation or embedded parts (anchor bolts, guide rails) to meet requirements.
2. Remove rust and debris from foundation or embedded‑part surfaces to ensure flat mounting surfaces.

Gate‑body Installation

Lifting & Positioning

Lift the gate steadily to installation position by lifting equipment. Keep uniform clearance (normally 2‑3 mm) between gate leaf and guide rails. Calibrate verticality with spirit level; allowable deviation ≤2 mm/m.

Fastening & Connection

1. Fasten gate onto embedded anchor bolts with symmetric tightening to avoid uneven stress.
2. Connect gate and guide rails via welding or bolting (per design requirements), ensure gate opens/closes without jamming.
3. For concrete troughs, secondary pouring is acceptable; extra fixing hardware is not required.

Sealing Inspection

Apply sealant to contact surfaces between gate leaf and gate frame. Inspect rubber water‑stop strip for intactness and no damage.

Measurement‑Control System Installation

Electrical Wiring

Connect power cables and control signal cables (RS485 etc.) per wiring diagram. Implement cable waterproof treatment (waterproof connectors, sealed conduits).

Lightning Protection & Grounding

The metal frame of gate shall be reliably grounded; grounding resistance ≤4 Ω.

Commissioning & Testing

Manual Commissioning

Switch to manual mode. Operate hand‑crank to test smooth gate movement; check for abnormal noise or jamming.

Electric Commissioning

Power on the unit. Operate full‑open / full‑close via control‑panel buttons. Calibrate zero‑point and full‑range of opening‑displacement sensor. Test remote open‑stop‑close operations via WeChat Mini‑Program or cloud platform. Test overload‑protection function (simulate rotor stall and verify automatic power‑off of motor).

Automatic Joint Commissioning

Connect to cloud platform. Test response speed and accuracy of linkage between water‑level / flow signals and gate actuation.

Acceptance & Hand‑over

Functional Acceptance

1. Verify gate tightness (no water leakage upon full closure), opening‑closing speed and control accuracy.
2. Validate normal performance of remote control and fault‑alarm functions (power‑off, overload etc.).

Document Hand‑over

Submit installation records, commissioning reports, equipment user manual and warranty documents.

Operation‑maintenance Training

Train operators on routine maintenance (lubrication, dirt removal) and fault‑handling procedures.

⚠️ Precautions

1. Avoid bumping against gate coating and sealing components during installation.
2. Take rain‑proof measures during rainy‑season construction to prevent moisture ingress into electric components.
3. Keep personnel away from moving gate parts during commissioning to avoid mechanical injury.

Note: The above steps serve only as reference. Installation shall be adjusted flexibly according to actual site conditions.
