360 Degree Rotating Fire Protection System

360 Degree Rotating Fire Protection System

How It Works

• A DC gear motor or stepper motor drives a worm/spur gearbox connected to the pivot assembly holding the nozzle head.
• The gearbox reduction lets a small motor rotate the (heavier, water-fed) head steadily and with enough torque to sweep reliably.
• A rotary union (swivel joint) feeds pressurized water into the rotating head from a fixed supply line without the hose twisting as the head turns.
• An IR flame/heat sensor can trigger automatic activation — starting rotation and opening a solenoid valve — the moment a fire signature is detected, rather than requiring manual activation.
• The head sweeps through its full rotation repeatedly while active, so no single angle around the mount goes uncovered for more than one sweep cycle.

Components

DC gear motor or stepper motor
Worm/spur gearbox (rotation drive)
Rotary union / swivel pipe joint
Pivot mount assembly + nozzle head
IR flame/heat sensor (automatic trigger)
Solenoid valve (water on/off)
Relay module + Arduino/microcontroller
Pressurized water supply line

Applications

• Factories and industrial warehouses
• Large storage and distribution facilities
• Server rooms and equipment bays
• Parking garages and large open indoor spaces

Advantages

• Eliminates the blind spots left by fixed-pattern sprinklers
• Sensor-triggered automatic activation reacts faster than manual response
• Gearbox-driven design retrofits onto existing sprinkler supply lines
• One rotating head can cover the area several fixed heads would otherwise be needed for

Sample Code — Flame-Triggered Rotation and Valve Control

// Simplified flame-trigger -> rotate + valve control - Arduino
int flameSensor = 2;
int rotationMotor = 5;
int solenoidValveRelay = 7;

void setup() {
  pinMode(flameSensor, INPUT);
  pinMode(rotationMotor, OUTPUT);
  pinMode(solenoidValveRelay, OUTPUT);
  Serial.begin(9600);
}

void loop() {
  bool fireDetected = digitalRead(flameSensor) == HIGH;

  if (fireDetected) {
    digitalWrite(solenoidValveRelay, HIGH); // open water supply
    digitalWrite(rotationMotor, HIGH);      // start 360-degree sweep
    Serial.println("Fire detected - rotating sprinkler activated");
  } else {
    digitalWrite(solenoidValveRelay, LOW);
    digitalWrite(rotationMotor, LOW);
  }
  delay(200);
}
