The utility model discloses an automatic drainage device of a pressure lead-in pipe of a compressor, which comprises a pressure lead-in pipe, a valve, a micro pressure interlock switch or a detecting instrument and an automatic drainage device. The automatic drainage device comprises a drum-shaped container fixed on a solidified ground, and an inlet and an outlet are arranged at the upper end of the drum-shaped container respectively. A gas pressure lead-in pipe communicated with a process pipeline is communicated with the inlet, the micro pressure interlock switch or the detecting instrument is communicated with the outlet through the pressure lead-in pipe, and simultaneously a U-shaped pressurizing lead-in pipe communicated with an inner chamber of the drum-shaped container is installed at the lower end of the drum-shaped container. After the automatic drainage device is installed and fixed, water only needs to be fed through the inlet, defined amount of antifreeze solution can be added together with the wa
