The application discloses a ship electric rudder engine and belongs to the technical field of ship rudder engines.The ship electric rudder engine comprises a base used for fixing an integral assembly of the electric rudder engine, a heat dissipation bottom plate located on the top of the base and fixed on the top of the heat dissipation base through bolts and used for heat dissipation of the electric rudder engine assembly, a driving mechanism located on the top of the heat dissipation bottom plate and connected with the heat dissipation bottom plate through bolts and serving as a power source of the ship electric rudder engine, and a rudder plate located below the base and in transmission connection with the driving mechanism.The ship electric rudder engine has the beneficial effects that: during the operation of the device, the driving motor serves as a core power source; when the driving motor is started and rotated, the rotation of the rotating shaft directly drives the rudder plate to be adjusted at a corresponding angle, so that the turning operation of the ship is realized; the linear motion of the motor is converted into the rotary motion of the rudder plate through a series of mechanical transmission in the process, the accuracy and response speed of the turning are ensured, and the risk of hydraulic oil leakage is greatly reduced.

The present invention discloses a gas extraction directional drilling tool, including a hollow drill rod and a drill bit, wherein the hollow drill rod is connected to a high-pressure gas circuit at the rear, and a pneumatic motor is connected to the front end of the hollow drill rod, and the output shaft of the pneumatic motor is connected to the drill bit at the front; more than three front air pressure caps are evenly arranged along the circumference at the hollow drill rod behind the pneumatic motor, and each front air pressure cap is respectively connected to the high-pressure gas circuit, and each front air pressure cap is respectively provided with a front solenoid valve for controlling the working state of the corresponding front air pressure cap at the connection between the front air pressure cap and the high-pressure gas circuit; the lifting direction of each front air pressure cap is perpendicular to the axis of the hollow drill rod; and the high-pressure gas circuit extends backward to the high-pressure gas source outside the borehole. The present invention also discloses a corresponding drilling method. The present invention realizes self-advancing drilling, lowering the pipe while drilling, and timely supporting the borehole, and there is no need to perform a separate operation of inserting a gas extraction pipe after drilling, so that the entire drilling process is safer, time-saving and efficient, reduces the difficulty of operation, and improves work efficiency.
