[0002] During shipbuilding, a steering chair needs to be installed in the bridge. Most current steering chairs are either fixed with high legs or movable. However, the current design is not suitable for the docking and offshore steering consoles attached to the front wall of the bridge. A more adaptable steering chair needs to be designed for use.

[0003] Existing technology includes a device called "Steering Gear" (publication number CN105980246B). This technology avoids positioning the rudder downstream of the propeller, achieving CO2 reduction and high propulsion efficiency. It also features a rudder that ensures turning performance and quiet operation even at low ship speeds, and can be used for ship braking. The steering gear has a drive mechanism for rotating the rudder shaft and a power mechanism for driving this drive mechanism. The two rudder shafts are rotatably positioned on either side above the propeller shaft. Each rudder shaft connects to a rudder plate at the top of the rudder plate, which hangs down. Rotation of the rudder shaft allows the rudder plate to rotate from the side of the propeller to the downstream side.

[0004] Existing technology includes a system called "Ship Follow-up Steering System" (publication number CN103921928B), which discloses a ship follow-up steering system comprising a steering mechanism, a drive device for rotating the rudder shaft, and a power supply. The steering mechanism is sequentially connected to a data processing device and a display. The data processing device is connected to the drive device, the drive device is connected to the rudder shaft, the rudder shaft is connected to a rudder angle feedback device, the rudder angle feedback device is connected to the data processing device, and the power supply is connected to the display, the data processing device, and the rudder angle feedback device. The ship follow-up steering system of this invention has a simplified overall structure, achieves digital operation, is precise and reliable, and allows the operator to instantly understand and control the rudder angle during ship navigation, providing accurate information for course control.

[0005] However, this technology does not address the technical issues and solutions of this application. Utility Model Content
