Embodiment 1

[0008] Embodiment 1 is as shown in the accompanying drawing. A hollow cylindrical body 6 with a top but no bottom has a circular through hole in the center of the top cover, a sliding bearing 5 is tightly fitted into the through hole, and an upright joystick 2 is inserted into the circular through the sliding bearing 5. In the inner cavity of the cylinder body 6, at the top of the joystick 2 exposed outside the top cover of the cylinder body 6 is an upper threaded section 2b, below the upper threaded section 2b is an upper tenon section 2c, and there is a ring under the upper tenon section 2c The shape of the shoulder blade 2a presses on the top surface of the cylinder body 6 to position the joystick 2 up and down. A horizontally placed joystick handle 4 has a square tenon hole that matches the upper tenon section 2c. The joystick handle 4 is set on the upper tenon. The segment 2c is fixed with a nut screwed on the upper threaded segment 2b, and the control handle 4 is connect...

Embodiment 2

[0012] Embodiment 2 As shown in the accompanying drawings, a rubber joystick water sealing ring 3 is embedded on the contact part between the sliding bearing 5 and the joystick 2, that is, there is a circle of grooves (or both) on the joystick 2 at this position. Groove is all arranged on the corresponding position), and joystick water sealing ring 3 is just embedded on this groove. The control rod water sealing ring 3 is used to prevent the water entering the inner cavity of the cylinder body 6 from leaking out of the cylinder body 6 along the control rod 2 . Certainly, the number of the joystick water sealing circle 3 can be 2 or 3, and the water sealing effect is better. Others are all the same as in Example 1 and will not be described again.

Embodiment 3

[0013] Embodiment 3 As shown in the drawings, a rubber right-angle elbow water seal 8 is embedded on the contact part between the right-angle elbow 7 and the cylinder body 6, that is, the right-angle elbow 7 or the cylinder body 6 at this position There is a circle of grooves (or both corresponding parts have grooves), and the right-angle elbow water sealing ring 8 is embedded in the grooves. The right-angle elbow water sealing ring 8 is used to prevent the water entering the inner cavity of the cylinder body 6 from leaking out of the cylinder body 6 along the outer surface of the right-angle elbow 7 . Of course, the number of the right-angle elbow water sealing rings 8 can be 2 or 3, and the water sealing effect is better. Others are all the same as in Example 1 and will not be described again.

Abstract

The invention discloses a rudderless course control device for a ship, wherein the rudderless course control device is connected with a water spray propulsion system for the ship. The rudderless course control device mainly comprises a control handle (4), a cylinder (6) and a quarter bend (7), wherein, a vertical control lever (2) is inserted into an inner chamber of the cylinder (6) through a slide bearing (5) on a head cover of the cylinder, and the upper end and the lower end of the control lever (2) are integrated with the control handle (4) and the quarter bend (7) respectively; a head cover of the quarter bend (7) is equipped with a bend through hole (7a); a cylindrical wall at the upper part of the cylinder (6) is equipped with a horizontal pipe (6a); and a water inlet pipe (1) connected with a spray pipe of the water spray propulsion system for the ship is connected on a ring flange (6b) of the horizontal pipe (6a). In the invention, the water spraying direction of the quarterbend (7) is changed by rotating the control handle (4) so as to change and control the sailing direction of the ship, thus omitting rudders and reducing the sailing resistance of the ship.

Description

Technical field: [0001] The present invention relates to a ship steering device, in particular a steering device. Background technique: [0002] Modern ships, whether they are large ships in the sea or small ships in inland rivers, are generally propelled by propellers and controlled by rudders. The patent number is ZL98110697.8, an invention patent titled "a ship propulsion system and its ship", which provides a water jet propulsion system without propeller. But controlling the course of the ship still relies on the rudder. Obviously, the rudder works in water, which will inevitably increase the forward resistance of the ship. Invention content: [0003] The object of the present invention is to provide a ship's rudderless course control device connected with the ship's water jet propulsion system to reduce the resistance of the ship's navigation. [0004] For this reason, the technical solution that the present invention adopts is, a kind of ship's rudderless course c...
