Background

The skyscraper is a 6600kW reamer power self-propulsion cutter suction dredger; in order to improve the dredging condition more widely and more efficiently, a bridge is arranged on a ship body at the stern part, a cutter head is positioned at the foremost end of the bridge, the shallowest dredging depth is 6.5 meters, and the largest dredging depth can reach 35 meters. Because the movable maximum angle of the bridge is 60 degrees, and a water sealing system in a reamer motor cabin in the bridge has a small amount of water leakage, the water sealing system is accumulated for a long time and tends to soak equipment, the equipment in the cabin is expensive, the IP level cannot meet the immersion requirement, and the equipment cannot be soaked for a long time. When the bridge is inclined, the original sewage well device can not pump and drain bilge water completely, and the gear box part of the mud pump can be soaked in water for a long time, but the equipment can be damaged.

Two sewage pumps are arranged outside the sewage well, and the sewage pumping process is automatically completed through commands of a high-position (pump starting) sensor and a low-position (pump stopping) sensor in the sewage well. It is theorized that the sump is positioned at this location and that when the bridge is rotated to a maximum angle of 60 degrees, the high sensor positioned within the sump will cause malfunction of the sump pump, not only for the purpose of not draining, but also possibly damaging the sump pump, as shown in fig. 1.
