Oil well underground monitoring device with image monitoring function

The utility model relates to an oil well underground monitoring device with an image monitoring function, which comprises a cavity pipe body, joints are arranged at the open ends of the two ends of the pipe body, four independent grooves are formed in the pipe wall of the pipe body, the first groove and the fourth groove are respectively a circuit cavity and a sensing detection cavity, and the second groove and the third groove are respectively a closed detection cavity and a semi-closed detection cavity. The grooves are sequentially communicated through wiring pipes; a power supply and a circuit box are arranged in the circuit cavity; a first pressure sensor, a second pressure sensor and a temperature sensor are arranged in the sensing detection cavity; an image collector is arranged in the closed detection cavity, and a probe is arranged in the semi-closed detection cavity. The power supply is separated from the sensor and the detection device, so that faults and potential safety hazards caused by water see
