The invention discloses an underwater towing device for a floating test of a navigation body, which is characterized in that a smooth sliding rail and a traveling rack are arranged on a frame, and the smooth sliding rail and the traveling rack are arranged in parallel; a power unit and an advancing gear are arranged on the dragging trolley, the dragging trolley is arranged on the smooth sliding rail, the power unit is fixed in the dragging trolley, an output shaft of the power unit is connected with the advancing gear, and the advancing gear is meshed with the advancing rack; a plurality of brackets are fixedly arranged at the top of the dragging trolley in parallel at intervals in a detachable connection mode, clamping and releasing mechanisms are fixedly arranged on the two sides of the brackets in a detachable connection mode, fixing plug pins controlled by electromagnetic force and elastic force jointly are arranged in the clamping and releasing mechanisms, and a fixing groove is formed in the floating body model. The floating body model is fixed and released by simultaneously controlling the extension and retraction of all the fixing bolts. The method has the characteristics of simplicity in operation, high release sensitivity and wide application range, and is beneficial to ensuring the accuracy and reliability of test data.

    本发明公开了一种用于航行体上浮试验的水下拖曳装置,在框架上设有光滑滑轨和行进齿条,光滑滑轨和行进齿条相互平行布设;在拖拽小车上设有动力单元以及行进齿轮,拖拽小车置于光滑滑轨上,动力单元固定在拖拽小车内部,动力单元的输出轴和行进齿轮相连,行进齿轮和行进齿条相啮合;若干个托架以可拆卸的连接方式平行间隔固定设在拖拽小车的顶部,在托架两侧以可拆卸的连接方式固定设有夹持释放机构,夹持释放机构内设有由电磁力和弹力共同控制的固定插销,浮体模型上设有固定槽,通过同时控制所有固定插销的伸出和收回,实现对浮体模型的固定和释放。具有操作简单、释放灵敏度高、适用范围广的特点,有利于保证试验数据准确可靠。
