Steering device of ship propeller

Abstract

The utility model discloses a steering device of a ship propeller. The steering device comprises a shell, a steering spindle; a buckling device; the steering device is characterized in that the steering device further comprises a transmission mechanism, the transmission mechanism comprises an input end, a first output end and a second output end, the first output end is in transmission with the steering main shaft, and a cam mechanism is arranged at the second output end; when the rotating angle of the steering main shaft from the zero position is within a set threshold angle [alpha, beta], the buckling device is in a locking state; and when the rotating angle of the steering main shaft from the zero position is beyond the set threshold angle [alpha, beta], the buckling device is in an unlocked state. The steering device has the advantages that the rotation angle threshold value of the steering main shaft is set, stability of the ship during steering is guaranteed (at the moment, the steering device is fixedly connected with the ship body), collision acting force can be effectively weakened in the advancing process (at the moment, the steering device is connected with the ship body in a turnover mode), and a motor of the propeller is prevented from being strongly collided frontally; and the service lives of the motor and the transmission device are prolonged.

Description

technical field [0001] The invention relates to a ship direction control device, in particular to a steering device for a ship propeller. Background technique [0002] The ship propeller is an energy converter in the ship propulsion device, which converts the power generated by the engine into the thrust of the ship to overcome the resistance of the ship navigating in the water and push the ship forward. [0003] There are many types of ship propellers. According to different principles, there are usually propellers, water jet propellers, special propellers, etc. The propellers provide power for the ship to move forward, and changing the direction of the ship is controlled by a steering device that can be linked with the propeller. In the prior art, the commonly used steering devices include electric steering control and mechanical steering control. Realize the steering system of the propeller ship, the steering system includes: steering wheel, set above the hull; angle sen...

AI Technical Summary

Problems solved by technology

[0005] The bottom of the ship may encounter obstacles such as reefs during navigation. In order to avoid direct collision between the propeller and obstacles, the steering device is usually rotatably fixed on the hull, and the propeller is connected to the bottom of the steering device. However, Most of the existing mechanical steering devices are fixed on the hull with a snap-in structure (such as using a hook to hang the crossbar). After the obstacle, until the buckle of the steering device is disengaged by the collision force, the propeller can be turned over together with the steering device body (the motor is lifted from the water), so as to prevent the motor of the propeller from being damaged by the obstacle. Although this buckle structure can disengage the buckle when a certain collision force occurs, this disengagement method requires the propeller to be subjected to sufficient collision force before it can be realized. If the force generated by the collision cannot make the buckle disengage, then The motor is subject to direct frontal strong impact, frequent impact will shorten the service life of the motor, especially for the steering device with mechanical transmission structure, the impact and damage will be great, which will reduce the reliability and safety of product use
