Abstract

The invention discloses a hydraulic blockage fault alarming device of a steering engine of a ship, and relates to the technical field of manufacturing of ships. The hydraulic blockage fault alarming device comprises an autopilot and a reversing valve, wherein the reversing valve comprises a valve body and a reversing valve element; the reversing valve element is arranged in a channel of the valve body; valve element monitoring devices are arranged at two ends of the reversing valve element; the autopilot is respectively connected with a left rudder relay and a right rudder relay through wires; the left rudder relay and the right rudder relay are respectively connected with the valve element monitoring devices at two ends of the reversing valve element through wires; and the left rudder relay and the right rudder relay are respectively connected with an audible and visual alarm lamp through wires. By the hydraulic blockage fault alarming device of the steering engine of the ship, the problems that time and labor are wasted in a confirming process when hydraulic blockage of the steering engine of the ship occurs and the navigation safety of the ship is affected can be solved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to an alarm device for a hydraulic blocking failure of a hydraulic steering gear with multiple steering systems on a ship. Background technique [0002] There is a main operating mechanism in ship course control equipment called hydraulic steering gear. In large ships, hydraulic steering gear often uses two sets of power systems and control systems, which are used as power guarantees to improve the safety factor of ship navigation; hydraulic blocking indicators What is most important is that one of the main hydraulic parts (hydraulic pump, reversing valve, etc.) in the steering gear hydraulic system fails, causing the entire hydraulic system to fail to work. The hydraulic blockage of the ship steering gear will cause the steering gear to fail and the ship will lose course control ability, there is the possibility of serious accidents such as collision, grounding, grounding, etc...
