喷泉泵水景水下设备漂浮式安装平台用升降装置系统是应用于喷泉水景中的一种机电装置。该装置由安装在平台上的卷扬机装置、钢索卷筒组件传动轴、钢索卷筒组件及其钢索、钢索卷筒组件支承轴套组件、钢索导向定滑轮、钢索定位定滑轮、水体底面定位基础及钢索末端固定环等零部件组成。当漂浮式平台处于工作位置时，卷扬机装置的电动机获得给定转向的启动信号，电动机转动，钢索卷筒组件传动轴带动钢索卷筒组件转动，将钢索缠绕在卷筒上，平台下降至给定位置时，电动机停止转动;当处于下降位置平台上的电动机获得反转信号时，电动机反转，钢索卷筒组件释放钢索，平台在水的浮力作用下上升至工作位置，电动机停止转动，平台完成下降与上升动作。

The lifting device system for floating installation platform of fountain pump underwater equipment is an electromechanical device used in fountain water scenery. The device consists of hoist device installed on the platform, transmission shaft of steel cable drum assembly, steel cable drum assembly and its cable, supporting sleeve assembly of steel cable drum assembly, steel cable guiding fixed pulley, steel cable positioning fixed pulley, water bottom positioning foundation and steel cable end fixed ring, etc. When the floating platform is in the working position, the motor of the hoister device obtains the starting signal of a given steering direction. The motor rotates. The transmission shaft of the cable drum assembly drives the cable drum assembly to rotate. The steel cable is wound on the drum and the motor stops turning when the platform drops to a given position. When the motor obtains the reversal signal, the motor reverses, the cable reel component releases the cable, the platform rises to the working position under the action of water buoyancy, the motor stops rotating, and the platform completes the descending and ascending action.
