Fault detection device for spraying dust suppression system

The utility model discloses a fault detection device for a spraying dust suppression system, and relates to the technical field of fault detection devices, the fault detection device for the spraying dust suppression system is provided with a detection water pump, a three-way pipe, a flow sensor and the like, and when the spraying dust suppression system fails and cannot work, the detection water pump is used for injecting water into a water distribution pipe; water flow does not pass through the water supply hose, so that if the water distribution pipe is normal, the spray header can normally spray outwards, when the spray header is damaged, part of the spray header cannot work, the faulted spray header can be quickly confirmed, meanwhile, the water flow enters the water supply hose through the water distribution pipe, and if the water supply hose is blocked and damaged, the water flow cannot flow into the three-way pipe. When the water supply hose is damaged, namely the water flow is not detected in the fir
