The system architecture of electric riot-control water cannon is built on the integrated framework of fluid dynamics and electric mechanical energy conversion. Its core function is to achieve crowd dispersal effect through directional water kinetic energy. Electric riot-control water cannon is a mechatronics platform that integrates water storage container, pressure module and vector injection device. The power source adopts a high-pressure plunger pump group driven by a permanent magnet synchronous motor to achieve linear control of water pressure output.
The energy conversion path of electric riot-control water cannon follows the conversion chain from electrical energy to mechanical energy and then to fluid kinetic energy. The variable frequency speed regulation system matches the corresponding relationship between the pump group speed and the nozzle back pressure in real time. The precise control of the injection trajectory relies on the multi-degree-of-freedom shaft structure of the vector nozzle, and the servo motor adjusts the elevation and azimuth angles through the worm gear transmission. The pressurization process of the water body adopts multi-stage compression technology, and each pressure chamber is equipped with a pressure relief valve to form a pressure gradient buffer layer.
The safety protection mechanism of electric riot-control water cannon is embedded in the closed-loop control system. The Hall sensor monitors the motor load current fluctuation and triggers the overload protection program. The adjustment of the water curtain shape depends on the turbulence suppression algorithm. The spiral guide vane is set inside the nozzle to reduce the Reynolds number and form a continuous columnar jet. The water quality filtration unit integrates a self-cleaning filter system to prevent suspended particles from blocking the flow channel.
The essence of electric riot-control water cannon is to maintain the impact force of the water body below the human tolerance threshold through precise energy density control, while maximizing the kinetic energy transfer efficiency.
