The invention discloses an unpowered self-stabilizing water surface hydrological instrument. The hydrological instrument comprises a cavity upper end cover, a cavity lower end cover, a lithium battery, a communication circuit board, a functional circuit board, a cavity shell, a buoyancy shell, an underwater acoustic transducer and a water entry detection sensor, the cavity upper end cover, the cavity lower end cover and the cavity shell form a closed cavity, and the lithium battery, the communication circuit board and the functional circuit board are arranged in the closed cavity; the closed cavity is located at the bottom in the buoyancy shell; the communication circuit board and the functional circuit board are respectively connected with the lithium battery; the underwater acoustic transducer is arranged at the bottom of the buoyancy shell and is connected with the functional circuit board; the water entry detection sensor is arranged on the buoyancy shell and used for detecting whether the hydrological instrument enters water or not and controlling the hydrological instrument to be started after the hydrological instrument enters the water. According to the hydrological instrument, the gyroscopic effect can be formed by utilizing impact of water flow on the buoyancy shell, basic positioning of the hydrological instrument is achieved under the unpowered condition, and it is guaranteed that the measurement depth direction is vertically downward.
本发明公开了一种无动力自稳定水面水文仪,所述水文仪包括腔体上端盖、腔体下端盖、锂电池、通讯电路板、功能电路板、腔体壳体、浮力壳体、水声换能器和入水检测传感器;腔体上端盖与腔体下端盖和腔体壳体形成密闭腔体,所述锂电池、通讯电路板、功能电路板设于所述密闭腔体内;密闭腔体位于浮力壳体内底部;所述通讯电路板和功能电路板分别与锂电池连接;所述水声换能器设于浮力壳体底部,与功能电路板相连;所述入水检测传感器设于浮力壳体上,用于检测水文仪是否入水,并在水文仪入水后控制其开机。本发明的水文仪可利用水流对浮力壳体的冲击形成陀螺效应,在无动力的情况下实现对水文仪位置的基本定位并保证测量深度方向竖直向下。
