The invention discloses a depth-adjustable Doppler current meter, and belongs to the technical field of current meters, the depth-adjustable Doppler current meter comprises a Doppler current meter body, a carrier plate is installed below the Doppler current meter body, buoyancy tanks are symmetrically arranged at the edge of the lower surface of the carrier plate, a base is arranged below the carrier plate, and the base is connected with the carrier plate through a connecting rod. A sleeve is installed between the base and the carrying plate, a telescopic rod is movably connected to the top end of the sleeve, a limiting block is arranged at the bottom end of the telescopic rod, and the limiting block is located on the inner side of the sleeve. The floating box installed at the edge of the bottom of the carrier plate is utilized, the telescopic rod is matched with the sleeve to stretch out and draw back so that the Doppler current meter body installed on the base can float on the water surface, and meanwhile the detection end of the Doppler current meter body corresponds to the flowing direction of the water body, so that the flow speed of the water body is detected. Therefore, the Doppler current meter body can be automatically adjusted according to the depths of different water bodies, and the applicability during detection is improved.
本发明公开了深度可调式多普勒流速仪,属于流速仪技术领域,深度可调式多普勒流速仪,包括多普勒流速仪本体,所述多普勒流速仪本体下方安装有载板,所述载板下表面边缘处对称设有浮箱,所述载板下方设有底座,且底座与载板之间安装有套筒,所述套筒顶端活动连接有伸缩杆,所述伸缩杆底端设有限位块,且限位块位于套筒的内侧,它可以实现,利用载板底部边缘处安装的浮箱并利用伸缩杆配合套筒伸缩使底座上安装的多普勒流速仪本体漂浮在水面处,同时使多普勒流速仪本体得检测端与水体流动的方向相对应,从而对水体的流速进行检测,因此可根据不同水体的深度自行调节多普勒流速仪本体,提高了检测时的适用性。
