The invention discloses a mining belt permanent magnet roller power detection device. The device comprises an oil tank, a plunger pump, a pilot overflow valve, an electromagnetic overflow valve, a remote control overflow valve, a pressure sensor and a controller. The plunger pump pumps hydraulic oil in the oil tank into the pilot overflow valve and the electromagnetic overflow valve according to the rotation of the permanent magnet roller, and the hydraulic oil flows into the oil tank after passing through the pilot overflow valve and the electromagnetic overflow valve; the pressure sensor detects the pressure in the pipeline and sends the pressure to the controller; and the controller determines the power of the permanent magnet roller according to the pressure. The power of the permanentmagnet roller is detected by improving the structure of the device, the manufacturing cost is only more than 13 thousand yuan, and compared with the traditional technical scheme that a frequency converter and a rheostat are
