Converging station device for measuring single-hole flow

The utility model belongs to the technical field of drill site single-hole flow inspection, and relates to a junction station device for measuring single-hole flow, which comprises a junction station main body, more than one group of measuring components arranged on the junction station main body, and a water tank connected with the junction station main body, the water tank is communicated with the measuring assembly through a water pipe. During measurement, the measuring rod is inserted into a measuring pipeline through the second measuring port, the measuring rod does not need to be arranged in the pipeline for a long time, the measuring rod is effectively prevented from being damaged by water and coal ash, and the sealing cover is covered when measurement is not needed; the device has a single-hole concentration measurement function, when the single-hole concentration is measured, the water pipe is pulled out, a gas taking pipe of the optical gas detector is inserted into the gas nozzle, and the single-ho
