Description

Technical Field

[0001] This utility model belongs to the field of cableway ferry technology, specifically relating to a cableway ferry rudder propeller device. Background Technology

[0002] The rudder propeller system of a cableway ferry controls the direction of the force exerted by the water flow on the cableway ferry by simultaneously changing the direction of two rudder blades, thus providing power to the cableway ferry and ensuring the stability and flexibility of the vessel during navigation.

[0003] Cableway ferries are used in ecologically sensitive and resource-scarce remote areas. They move laterally by generating water thrust through changes in rudder angles, utilizing water flow as a power source that is environmentally friendly and pollution-free, aligning with the principle of "green shipping." Currently, most cableway ferries are catamarans, thus having two rudders. Changing the rudder angle requires manual rotation of the rudder stick, which cannot be operated simultaneously, hindering the ferry's efficiency in changing direction. Therefore, a rudder propeller device is needed to rotate both rudders by the same angle simultaneously. Traditional electric rudder propellers significantly increase shipbuilding and ferry operating costs, making them impractical in resource-scarce remote areas. Therefore, a manually operated mechanical rudder propeller device needs to be designed to save energy and provide a foundation for the development of cableway ferries. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a rudder propeller device for a cableway ferry, including a manual rudder motor 1, the output shaft of which is connected to a rack via gears, and the rack is moved by rotating the manual rudder motor 1; a rudder cable 2, which connects to both ends of the rack; a connecting rod 3, the other ends of which are respectively connected to both ends of the connecting rod 3, and a rudder handle 4 is hinged to both ends of the connecting rod 3; and a rudder device, which includes a rudder stock 5, a rudder tube sleeve assembly 6, and a rudder blade 7, the rudder handle 4 being connected to the rudder stock 5, the rudder stock 5 being rotatably and tightly fitted with the rudder tube sleeve assembly 6, and the rudder blade being fixed at the bottom end of the rudder stock 5. 7; pulley 8, which guides the rudder cable 2 to move along a designated path; the crew member drives the rudder cable 2 to move left and right by rotating the manual steering gear 1, which in turn drives the rack and pinion to move the rudder cable 2. This action causes the connecting rod 3 to be displaced, thereby driving the two rudder handles 4 to rotate synchronously; as the rudder handles 4 rotate, the rudder stick 5 further drives the two rudder blades 7 to deflect synchronously; the rotation of the rudder blades 7 changes the direction of the force exerted on it by the water flow, thereby providing the necessary power for the cableway ferry to navigate smoothly; the pulley 8 guides the rudder cable 2 to move along a designated path, so that the whole can be arranged according to the deck conditions.

[0028] Specifically, the rudder cable 2 is provided with an adjusting rod 9 in the middle. In this embodiment, the path of the rudder cable 2 will change slightly at the swing point of the rudder handle 4 during the movement of the connecting rod 3, which will cause the rudder cable 2 to slack. The adjusting rod 9 is used to keep the rudder cable 2 taut at all times.

[0029] Specifically, the adjusting rod 9 includes a rod housing 10, the inside of which is provided with a sliding cavity 11. Both ends of the rod housing 10 are equipped with long rods 12 that can slide along the sliding cavity 11. The two outer ends of the long rods 12 are provided with steel cable connecting parts 13, and a strong spring 14 is connected between the two long rods 12. In this embodiment, the strong spring 14 will always strongly pull the steel cable connecting parts 13 on both sides and the rudder steel cable 2, so that the rudder steel cable 2 is always kept taut, and the rudder steel cable 2 is prevented from slackening during the movement of the connecting rod 3.

[0030] Specifically, the inner end of the long pull rod 12 is provided with a limiting block 15, and the two ends of the strong spring 14 are welded and fixed to the limiting block 15; in this embodiment, the limiting block 15 can improve the stability of the long pull rod 12 when sliding along the sliding cavity 11.

[0031] Specifically, the outer side of the limiting block 15 is a square block structure; in this embodiment, the square block design makes the limiting block 15 more stable relative to the pull rod housing 10.

[0032] Specifically, the end of the long pull rod 12 that contacts the limiting block 15 is provided with a threaded head, and the limiting block 15 is provided with a corresponding threaded groove and is threadedly connected; in this embodiment, the design of the long pull rod 12 and the limiting block 15 being threadedly connected facilitates assembly and disassembly.

[0033] Specifically, the outer sides of the two rudder handles 4 are also provided with rudder angle limiters 16 mounted on the deck; in this embodiment, the rudder angle limiters 16 serve to limit the displacement of the rudder handles 4, thereby limiting the rotation angle of the rudder blades 7.

[0034] Specifically, the rudder angle limiter 16 limits the rotation angle of the rudder 4 to 20° to 30°; in this embodiment, limiting the rotation angle of the rudder 4 to 20° to 30° is a preferred embodiment of this application, to avoid damage to the rudder cable 2 due to excessive rotation angle.

[0035] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0036] Working principle: The crew rotates the manual steering gear 1, which in turn drives the rack and pinion to move the rudder cable 2 left and right. This action causes the connecting rod 3 to shift, which in turn drives the two rudder handles 4 to rotate synchronously. As the rudder handles 4 rotate, the rudder stick 5 drives the two rudder blades 7 to deflect synchronously. The rotation of the rudder blades 7 changes the direction of the force exerted on them by the water flow, thus providing the necessary power for the cableway ferry to navigate smoothly. During this process, the strong spring 14 will always pull the two limit blocks 15, which in turn pulls the cable connection parts 13 on both sides and the rudder cable 2, keeping the rudder cable 2 taut and preventing it from slackening during the movement of the connecting rod 3.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
