The invention discloses an underwater propeller thrust testing device and method. The underwater propeller thrust testing device comprises an adjustable frame, a push-pull dynamometer, a propeller pose adjustable mounting table and a lever, the push-pull dynamometer and the thruster pose adjustable mounting table are arranged on the upper side and the lower side of the adjustable frame respectively; the push-pull dynamometer comprises a control box, a gradienter and a dynamometer; the control box is mounted on the adjustable frame, the gradienter is mounted on the control box, the dynamometer is arranged in the control box, the tension bar end of the dynamometer is connected with one end of the lever, the lever is rotatably arranged on the adjustable frame, and the propeller pose adjustable mounting table is connected with the other end of the lever. The distance from the push-pull end of the dynamometer to the lever rotating shaft is equal to the distance from the propeller axis to the lever rotating shaft. The device is simple and convenient in design and higher in precision, can be quickly disassembled and assembled, can be adjusted according to different pool scales, does not need to modify the pools during installation, and has higher universality and adaptability.

    一种水下推进器推力测试装置及方法,包含可调节框架、推拉测力器、推进器位姿可调安装台和杠杆;推拉测力器和推力器位姿可调安装台分别设置在可调节框架的上下侧;推拉测力器包含控制盒、水平仪和测力计;控制盒安装在可调节框架上,水平仪安装在控制盒上,测力计布置在控制盒内,测力计的拉力杆端部与杠杆的一端连接,杠杆可转动地设置在可调节框架上,推进器位姿可调安装台与杠杆的另一端连接,测力计的推拉端至杠杆转轴的距离与推进器轴线至杠杆转轴的距离相等。本发明设计简便,精度更高,可实现快速拆装,可针对不同水池规模进行调节,安装时不需要对水池进行改造,更具普遍性和适应性。
