Embodiment 1

[0008] Example 1 is shown in the drawings. A hollow cylindrical body 6 with a top and no bottom, a circular through hole in the center of the top cover, a sliding bearing 5 is embedded in the through hole, and an upright joystick 2 is inserted into the circle through the sliding bearing 5 In the inner cavity of the cylinder 6, at the top of the joystick 2 exposed outside the top cover of the cylinder 6 is an upper threaded section 2b, below the upper threaded section 2b is a section of upper tenon section 2c, and under the upper tenon section 2c is a ring The upper shoulder blade 2a is pressed on the top surface of the cylinder 6 to position the joystick 2 up and down. A horizontally placed joystick 4 has a square tenon hole that matches the upper tenon section 2c, and the joystick 4 is placed on the upper tenon. The segment 2c is fixed with a nut screwed on the upper threaded segment 2b, and the operating handle 4 and the operating rod 2 are connected as a whole.

Embodiment 2

[0012] Embodiment 2 is shown in the figure. A rubber control rod sealing ring 3 is embedded in the contact part of the sliding bearing 5 and the joystick 2. That is, there is a ring of grooves (or both There are grooves on the corresponding parts), and the joystick sealing ring 3 is embedded in the groove. The operating rod sealing ring 3 is used to prevent the water entering the inner cavity of the cylindrical body 6 from leaking out of the cylindrical body 6 along the operating rod 2. Of course, the number of the joystick sealing ring 3 can be two or three, and the sealing effect is better. Others are the same as Embodiment 1, and will not be described again.

Embodiment 3

[0013] Example 3 As shown in the figure, a rubber-made right-angle elbow sealing ring 8 is embedded on the contact part of the right-angle elbow 7 and the cylindrical body 6, that is, the right-angle elbow 7 or the cylindrical body 6 in this part There is a ring of grooves (or both corresponding parts have grooves), and the right-angle elbow water sealing ring 8 is embedded in the groove. The right-angle elbow water sealing ring 8 is used to prevent the water entering the inner cavity of the cylindrical body 6 from leaking out of the cylindrical body 6 along the outer surface of the right-angle elbow 7. Of course, the number of right-angle elbow sealing rings 8 can be two or three, and the sealing effect is better. Others are the same as Embodiment 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 invention relates to a ship driving device, in particular a heading control device. Background technique: [0002] Modern ships, whether they are large ships in the sea or small ships in inland rivers, generally use propellers for propulsion and rudder to control their course. The patent number is ZL98110697.8 and the invention patent named "a ship propulsion system and its ship" provides a water jet propulsion system without propeller. But controlling the ship's course still relies on the rudder. Obviously, when the rudder works in the water, it will inevitably increase the forward resistance of the ship. Summary of the invention: [0003] The purpose of the present invention is to provide a ship's rudderless heading control device connected with the ship's water jet propulsion system, so as to reduce the resistance of the ship's navigation. [0004] To this end, the technical solution adopted by the present invention is a ship's rudderless heading co...
