[0002] An open-hull ship is a type of ship used to transport and unload bulk cargoes such as mud and sand. The hull of an open-hull ship is designed as two independent hull parts. It realizes the opening and closing operations of the two hull structures through an opening and closing structure. The opening and closing structure is conducive to improving the efficiency of cargo unloading.

[0003] Since the opening and closing structure used for open-hull ships often only uses a single drive structure composed of a single oil cylinder and an articulated arm to apply driving force to the two single hulls to realize automatic opening and closing operations during actual operation, this method has the problem of a single opening and closing drive structure and is easily damaged and deflected due to the impact force applied by the hull, which affects the stability and safety of the open-hull ship during opening and closing operations. In addition, the opening and closing spacing is not easy to be intelligently monitored and regulated, which affects the opening and closing effect of the device and can no longer meet people's needs. For this reason, we propose a new opening and closing structure for open-hull ships to solve the above-mentioned problems. Utility Model Content
