The invention discloses a safety and protection monitoring device for a network computer room. The safety and protection monitoring device comprises a fixing seat, a driving motor is fixedly connectedto the top of the fixing seat, and the output end of the driving motor is fixedly sleeved with a cam. A first connecting rod is rotatably connected to the end, away from the driving motor, of the cam, a second connecting rod is rotatably connected to the end, away from the cam, of the first connecting rod, and a transmission rod is rotatably connected to the end, away from the first connecting rod, of the second connecting rod. A sliding opening corresponding to the transmission rod is formed in the top of the fixing seat, the end, away from the second connecting rod, of the transmission rodpenetrates through the sliding opening and extends downwards, and a sliding rod is fixedly connected into the sliding opening. A penetration opening corresponding to the sliding rod is formed in the transmission rod, the sliding rod is sleeved with a first spring, and the two ends of the first spring are fixedly connected with the transmission rod and the inner wall of the sliding opening correspondingly. According to the safety and protection monitoring device for the network computer room, by arranging a plurality of transmission mechanisms, a monitoring probe can freely move in position, and thus the monitoring range is increased.
