when the stay cable connecting piece is installed, the hose connecting cloth is adhered and fixed to the outer membrane surface of the inflatable floating hose, so that the middle stay cable connecting piece among the three stay cable connecting pieces faces upwards;
each stay cable connector is provided with one stay cable, the other end of each stay cable is arranged on a ship, and the laying direction of the inflatable floating hose can be adjusted by adjusting three stay cables, so that the inflatable floating hose can be rapidly laid.
7. A method of laying a balloon-type floating hose for use in transportation and transfer of liquid material on a vessel according to claim 6, wherein the stay cable connector comprises a fixing portion fixedly mounted to an inner side surface of the hose connecting cloth and a connecting portion extending from the mounting opening for connecting the stay cable.
