DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 6 As shown, a device for adjusting the stern shaft steering of a ship comprises an operating box 1 and a stern shaft 2, wherein the stern shaft 2 is sleeved with a propeller 3, a rudder shaft 4 is rotatably mounted on one side of the lower surface of the operating box 1, the rudder shaft 4 is sleeved with a ship rudder 5, and the upper end of the rudder shaft 4 extends into the operating box 1 and is sleeved with a gear 6;

[0025] A vertical plate 7 is fixedly installed on one side of the bottom of the operation box 1, a screw rod 8 is rotatably installed between the vertical plate 7 and one side of the inner wall of the operation box 1, a movable plate 9 is threadedly arranged on one side of the screw rod 8, a rack 10 is fixedly installed on one side of the movable plate 9, and the rack 10 is meshed with the gear 6;

[0026] A motor 701 is fixedly mounted on one side of the vertical plate 7 , and one end of the screw rod 8 passes through the vertical plate 7 and is fixedly connected to the output shaft end of the motor 701 .

[0027] A cross bar 11 is fixedly installed between the vertical plate 7 and one side of the inner wall of the operation box 1 , and the movable plate 9 is slidably arranged on one side of the shaft of the cross bar 11 .

[0028] The staff controls the rotation of the stern shaft 2 through the through hole, so that it drives the propeller 3 to rotate, so that the ship sails on the water surface. When it is necessary to adjust the steering of the rudder shaft 4, the staff starts the motor 701 to make its output shaft end drive the screw 8 to rotate. The rotating screw 8 drives the movable plate 9 and the rack 10 to move along the direction of the cross bar 11 by screwing in the thread. Under the meshing action of the rack 10 and the gear 6, the rudder shaft 4 drives the rudder 5 to swing. The staff does not need to continuously operate the rudder shaft 4, which reduces the workload of the staff. In addition, the cooperation of the screw 8, the rack 10 and the gear 6 can achieve high-precision transmission and positioning with high precision, thereby improving the driving stability of the ship and the accuracy of heading control.

[0029] In another embodiment of the present invention, a mounting frame 12 is fixedly mounted on one side of the vertical plate 7 close to the motor 701 , and button switches 13 are arranged on both sides of the mounting frame 12 . The two button switches 13 are electrically connected to the motor 701 .

[0030] A rotating rod 14 is rotatably mounted on the inner wall of the operation box 1 near the button switch 13 , a rotating plate 15 is fixedly mounted on one end of the rotating rod 14 , and an arc block 16 is fixedly mounted on the rotating plate 15 near the button switch 13 .

[0031] One end of the rotating rod 14 away from the arc block 16 passes through the operation box 1 and is fixedly mounted with a handle 17 .

[0032] The staff pushes the handle 17 to drive the rotating rod 14 and the rotating plate 15 to rotate. When the arc block 16 moves to the position of one of the button switches 13 and presses it down, the output shaft of the motor 701 rotates forward, the rack 10 moves, and the rudder shaft 4 rotates. When the arc block 16 moves to the position of another button switch 13 and presses it down, the output shaft of the motor 701 rotates reversely, the rack 10 moves in the opposite direction, and the rudder shaft 4 rotates in the opposite direction, which makes it convenient for the staff to control the steering of the output shaft of the motor 701, thereby making it convenient for the staff to control the steering of the rudder shaft 4.

[0033] In another embodiment of the utility model, a torsion spring 18 is arranged between the rotating plate 15 and one side of the inner wall of the operating box 1 , one end of the torsion spring 18 is fixedly mounted on one side of the rotating plate 15 , and the other end of the torsion spring 18 is fixedly mounted on one side of the inner wall of the operating box 1 .

[0034] By providing the torsion spring 18, when the staff releases the handle 17, the handle 17 rotates to the initial position under the elastic force of the torsion spring 18, and the staff does not need to manually reset the handle 17, further reducing the workload of the staff.

[0035] The working principle of the device for adjusting the stern shaft steering of a ship:

[0036] When in use, the staff controls the rotation of the stern shaft 2 through the hole, so that it drives the propeller 3 to rotate, so that the ship sails on the water surface. When it is necessary to adjust the steering of the rudder shaft 4, the staff starts the motor 701 to make its output shaft end drive the screw rod 8 to rotate. The rotating screw rod 8 drives the movable plate 9 and the rack 10 to move along the direction of the cross bar 11 by screwing in the thread. Under the meshing action of the rack 10 and the gear 6, the rudder shaft 4 drives the rudder 5 to swing. The staff does not need to continuously operate the rudder shaft 4, which reduces the workload of the staff. In addition, the cooperation of the screw rod 8, the rack 10 and the gear 6 can achieve high-precision transmission and positioning with high precision, thereby improving the driving stability of the ship and the accuracy of heading control.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
