s2: the fire fighting reel pipe (10) penetrates into the interior of the clamping piece (21) in sequence, the infrared sensor (17) senses the fire fighting reel pipe (10) in real time, the PLC (12) analyzes and judges according to a data value and sends an opening instruction to the fixed cylinder (23), the clamping piece (21) moves along the horizontal central line direction of the fixed inner pipe (18) through pushing of the fixed cylinder (23), the clamping expansion spring (20) is enabled to synchronously expand and contract towards the horizontal central line direction of the fixed inner pipe (18), so that the fire fighting reel pipe (10) is fixed, and the fire fighting reel pipe (10) is prevented from falling off when the pressure is high;
s3: the fire-fighting water tank (2) stably outputs water source sequentially through the water outlet pipe (4), the pressure stabilizing water pump (3), the extension pipe (6), the fixed inner pipe (18), the fire-fighting reelpipe (10), the flow meter (15) and the fire-fighting nozzle (16) to complete the fire-fighting process;
s4: the PLC (12) detects the real-time flow of each group of fire-fighting spray heads (16) through the flow meter (15) and judges whether the number of the valves (5) needs to be increased or decreased so as to stabilize the water pressure;
s5: PLC controller (12) detect the inside real-time water level of fire water tank (2) through level sensor (7), judge whether need to send the instruction to alarm (14), carry out real-time early warning, use external water pipe (9) to add water in fire water tank (2), guarantee that water pressure is stable.
