The setting of control valve A and control valve B enables the system to independently control the spraying of different areas, thereby improving the flexibility and pertinence of the spraying. The use of swing arm nozzle 1 and swing arm nozzle 2 not only increases the spraying range, but also can automatically adjust the spraying angle according to environmental changes, further improving the uniformity and coverage effect of the spraying; the PLC controller 1 is connected with the detection unit 2, and the PLC controller 1 controls the spraying according to the information transmitted by the detection unit 2.

[0016] Specifically, the detection unit 2 is remotely connected to a dust detector a9 and a dust detector b10; the dust detector a9 is arranged on the wall of the first branch pipe 14 between the swing arm nozzle 11 and the control valve A7; the dust detector b10 is arranged on the wall of the second branch pipe 15 between the swing arm nozzle 2 12 and the control valve B8. The remote connection function of the detection unit 2 enables the device to receive the monitoring data of the dust detector a and the dust detector b in real time, and automatically start or adjust the spraying according to the dust concentration in the environment, thereby effectively reducing dust pollution and protecting the environmental quality.

[0017] Specifically, the main pipe 13 is connected to the first branch pipe 14 and the second branch pipe 15 respectively through a reducing joint.

[0018] Specifically, the main pipe 13 is a high-pressure rubber hose with a diameter of 50 mm; the first branch pipe 14 and the second branch pipe 15 are both iron pipes with a diameter of 15 mm.

[0019] Specifically, the first branch pipe 14 and the second branch pipe 15 are arranged on the main pipe 13 with an interval of 6 m.

[0020] The operation process is as follows:

[0021] 1. Turn on the sprinkler: First, make sure there is enough water in the sprinkler pool, and then start the PLC controller 1 in the control system.

[0022] 2. Adjust the water flow: The PLC controller 1 will automatically adjust the flow control valve 3 according to the real-time data provided by the pressure sensor 6 to ensure that the sprinkler device can maintain the best working condition under different conditions.

[0023] 3. Ensure stable water pressure: The water pump 5 will continue to work to ensure that the spray device has stable water pressure and provide sufficient power for spraying.

[0024] 4. Automatically adjust the spraying: The PLC controller 1 will monitor the data of the pressure sensor 6 in real time and automatically adjust according to the actual pressure conditions to avoid waste of resources or poor spraying effect due to abnormal pressure.

[0025] 5.

[0026] 6. Increase the spraying range and automatically adjust the spraying angle: The swing arm nozzle 11 and the swing arm nozzle 2 12 can automatically adjust the spraying angle according to environmental changes, increase the spraying range, and improve the uniformity and coverage effect of the spray.

[0027] 7. Real-time monitoring of environmental dust concentration: The dust detector a9 and the dust detector b10 will monitor the dust concentration in the first branch pipe 14 and the second branch pipe 15 in real time, and transmit the data to the detection unit 2.

When the terminal device releases water at a flow rate of 0.94-1.5L / s, the whole water flow of the spray device pipeline is normal. The PYSK10 rocker arm sprinkler 7 is pressurized to 150-350kPa, and then quickly diffuses and evaporates in the air through the nozzle to absorb heat, so as to achieve the purpose of high-speed humidification, cooling, dust reduction, disinfection, and anti-static.
