PROBLEM TO BE SOLVED: To provide an underwater observation device that can perform stable observation by pressing an underwater observation part against a dam wall surface by an underwater propeller under normal conditions, can avoid an obstacle on the wall surface if there is an obstacle or the like on the dam wall surface, by temporarily moving away from the dam wall surface by ejection control of the underwater propeller, and can perform observation of the wall surface in a wide range by a clear image even in turbid water.SOLUTION: An underwater observation device includes a housing 2 having a hollow part filled with transparent liquid in which a transparent plate that can see through the outside is disposed on the surface facing the hollow part, a camera device 5 attached to the housing 2, which is arranged so that a lens part faces the transparent plate with the hollow part in between, a suspending device 7 for suspending the housing 2 through a suspending wire 8 and elevating/lowing the housing 2 underwater, and underwater propellers 9A and 9B provided to the housing 2 that can move the housing 2 underwater.SELECTED DRAWING: Figure 1

    【課題】水中推進器によって水中観察部を通常はダム壁面に押し付けて安定して観察できるようにすると共に、ダム壁面に障害物等がある場合は、水中推進器の噴出制御でダム壁面から一時的に離れることで壁面表面の障害物を回避でき、濁水中でも広い範囲で壁面の表面をきれいな画像で観察できる水中観察装置を提供する。【解決手段】透明な液体で充填される中空部を有し且つその中空部に臨む面に外部を透かして見ることができる透明板が配置された筐体2と、中空部を挟んで透明板にレンズ部が対向するように配置されて筐体2に取り付けられたカメラ装置5と、筐体2を吊下げワイヤ8を介して吊り下げてその筐体2を水中で昇降させる吊下げ装置7と、筐体2に設けられ且つ水中内でその筐体2を移動可能な水中推進器9A,9Bを設けた。【選択図】図1
