Double-bow spraying system of ultra-large trailing suction hopper dredger
A larboard mud pump and a starboard mud pump are installed in a mud pump cabin of a ship body, mud pipes of suction inlets of the larboard mud pump and the starboard mud pump, a tee joint, a four-way joint and a gate valve are installed on a mud pump cabin layer of the ship body, and the mud pipes of the left suction inlet and the right suction inlet are connected with a larboard mud cabin pumping channel and a right larboard mud cabin pumping channel respectively. The suction channels, the tee joints, the four-way joints and the gate valves are arranged in the suction channels, and the mud pumping outlets of the left mud pump and the right mud pump are respectively connected with respective double-bow spraying and blowing devices through mud discharging pipes. The double-bow spraying system has the functions of bow blowing or bow spraying operation of a traditional single dredge pump and bow spraying or bow blowing operation of serial connection of the port dredge pump and the starboard dredge pump, and also has the function of double-bow spraying and mud discharging of simultaneous operation of the port dredge pump and the starboard dredge pump. Compared with a traditional single bow jet, the mud discharging flow is doubled, the mud discharging time of a mud cabin of the ultra-large drag suction dredger is shortened by half, and the bow jet construction operation efficiency of the dredger is effectively improved.
本发明涉及一种超大型耙吸挖泥船双艏喷系统，船体泥泵舱内安装左舷泥泵和右舷泥泵，船体泥泵舱层安装左、右舷泥泵的吸入口的泥管、三通、四通及闸阀，左、右吸入口的泥管分别连接左舷泥舱抽仓通道、右左舷泥舱抽仓通道，并分别通过吸入通道以及吸入通道中的三通、四通及闸阀连接左、右舷泥泵的吸泥口，左、右舷泥泵的泵出泥浆口分别通过排出泥管连接各自的双艏喷艏吹装置。该双艏喷系统具备传统的单泥泵艏吹或艏喷作业以及左舷泥泵和右舷泥泵串联艏喷或艏吹作业功能外，还具备左舷泥泵以及右舷泥泵同时作业双艏喷卸泥功能。相比传统单艏喷卸泥流量提高一倍，使得超大型耙吸挖泥船泥舱卸泥时间缩短一半，有效提高了挖泥船的艏喷施工作业效率。
