UNDERGROUND IMAGING EQUIPMENT

Abstract

The underground imaging device consists of a cylindrical outer shell (200), an electronic component unit (6), and an automatic drainage unit (7). The cylindrical outer shell (200) has a water collection chamber (241, 20), a translucent window (245, 342) at the top of the cylindrical outer shell, a water inlet (443, 412) for water to flow from the outside into the water collection chamber, and a water diversion channel (444, 411) connected to the water inlet and positioned underground. The electronic component unit (6) includes the imaging module (8) which is oriented toward the window (245, 342). The automatic drainage unit (7) includes a water-pushing drive (71) which is activated to push water out of the water collection chamber (241, 20). Water is prevented from accumulating around the window so that the imaging module can operate correctly.
