Description

Technical Field

[0001] The utility model relates to the technical field of propulsion equipment, in particular to a variable pitch propulsion control device. Background Art

[0002] A propulsion control device refers to a device that controls the ship's propulsion system to achieve ship movement and maneuverability, including controlling the engine's thrust, direction and speed, as well as managing the ship's attitude and stability. Currently, the propulsion systems of most aircraft are configured such that the main engine in the cabin generates power, which is then transmitted to the outside of the cabin through a clutch and a reduction gearbox through a long shaft system, driving the propeller blades outside the cabin to rotate, ultimately achieving aircraft movement.

[0003] A Chinese patent with authorization announcement number CN217835989U discloses a propeller that is easy to adjust the pitch. By installing a motor, the motor can drive the threaded rod to rotate when it rotates. By installing a moving block, the moving block can be driven to move along the threaded rod when the threaded rod rotates. By installing a pull rod through a pin inside the movable seat, the pull rod is easy to rotate inside the movable seat. By installing a turntable, the propeller can drive the blades to rotate a certain angle when it rotates, thereby adjusting the pitch.

[0004] However, when the propulsion device mentioned above adjusts the pitch, no limit component is set. When the propeller is sailing in the water, it will encounter greater resistance. The resistance will indirectly drive the propeller to rotate, resulting in the adjustment accuracy being affected. Utility Model Content

[0020] Among them, the adjustment component includes a driving shaft 8, a main bevel gear 9, a slave bevel gear 10, a rotating shaft 11 and a connecting disk 12. The driving shaft 8 is rotatably arranged in the rotating drum 2, and a limiting component that cooperates with the end cover 4 is installed at one end of the driving shaft 8. The rotating shaft 11 is provided with multiple groups, and the multiple groups of rotating shafts 11 are rotatably arranged on the rotating drum 2.

[0022] Embodiment 2

[0023] like Figure 1-Figure 4As shown, the utility model proposes a variable pitch propulsion control device. On the basis of the above embodiments, this embodiment also discloses in detail the specific components of the limit assembly, which include a tension spring 13, an insertion shaft 14, a disk 15, a limit column 16, a limit hole 17 and a pull belt 18. A groove is provided at one end of the driving shaft 8, and the tension spring 13 is arranged in the groove. The insertion shaft 14 is connected to one end of the tension spring 13. An adapter is provided between the insertion shaft 14 and the driving shaft 8. The disk 15 is installed at one end of the insertion shaft 14 and is located on the outside of the end cover 4. A receiving groove 19 for accommodating the disk 15 is provided on the end cover 4. A plurality of groups of limit holes 17 are distributed circumferentially in the receiving groove 19. Limit columns 16 are interspersed in the corresponding limit holes 17.
