Fire extinguishing water discharge device operated by water pressure

A fire extinguishing water discharge device operated by water pressure, comprising:

• a support part in which a plurality of support plates are arranged at intervals in a front-rear direction;
• a fire extinguishing water discharge part hingedly coupled to any one of the support plates of the support part, the fire extinguishing water discharge part having a plurality of nozzles arranged at intervals on an upper surface thereof;
• a first driving unit connected between one end of any one of the support plates and one end of another support plate of the support part, the first driving unit being provided with a plurality of wheels on one side thereof in contact with a ground;
• a second driving unit connected between the other end of any one of the support plates and the other end of another support plate of the support part, the second driving unit being provided with a plurality of wheels on one side thereof in contact with the ground;
• and
• a control part spaced apart from the support part, one end of which is connected to a fire hydrant, the control part controlling water flow in each of a first fire extinguishing water supply pipe extending from the other end to the fire extinguishing water discharge part, a second fire extinguishing water supply pipe extending from the other end to the first driving unit, and a third fire extinguishing water supply pipe extending from the other end to the second driving unit,
• wherein the wheels of the first driving unit and the second driving unit are rotated by a hydraulic force generated by water flowing inside through the second fire extinguishing water supply pipe and the third fire extinguishing water supply pipe.
