The invention discloses a stability maintaining meteorological environment monitoring device. The stability maintaining meteorological environment monitoring device comprises a protective shell, a surveillance camera, a front clamping mechanism and a rear clamping mechanism. The surveillance camera, the front clamping mechanism and the rear clamping mechanism are all arranged in the protective shell. The front clamping mechanism clamps and fixes the front portion of the surveillance camera. The rear clamping mechanism clamps and fixes the rear portion of the surveillance camera. The rear clamping mechanism comprises two threaded rods, an upper moving rod, a lower moving rod and two clamping blocks. The threaded rods can rotate synchronously. An upper thread and a lower thread of the threaded rods are in opposite directions. The two clamping blocks are located between the two threaded rods. The rear portion of the surveillance camera is arranged between the two clamping blocks. The twothreaded rods rotate synchronously. The upper moving rod moves downwards along the corresponding threaded rod, he lower moving rod moves upwards along the corresponding threaded rod, and the two clamping blocks move accordingly to clamp and fix the rear portion of the surveillance camera. The stability maintaining meteorological environment monitoring device has the advantages of being reasonablein structure, convenient to mount and demount, high in stability and the like.
