Ship propeller stern shaft acceleration and deceleration device

Abstract

Ship propellers axis axis acceleration device, including: impeller, impeller consists of two parts, fix the impeller of the two parts on the axis of the axis through the screw, and the impeller and the axis of the axis are added with anti -sliding pads.The without sealing air cavity; the shell is composed of the upper and lower parts, fixing with the base through the screw, and fixing the structure of the base and the hull; there is a left and right air inlet on the shell, and the two airports compressed the air intake with the left and right compressed air intake.Copper pipe connection; left and right inlet copper pipes install left solenoid valve and right solenoid valve respectively; left and right solenoid valves are controlled by remotely accelerated and decelerating controllers; the controllers are powered by the uninterrupted power supply, and the invention controls the solenoid valve through the remote control handle to control the solenoid valve.Broken to control the direction of the air intake of compressed air. After the compressed air enters the shell, the impeller has force to transmit it to the axis through the impeller to effectively reduce or increase the speed of the axis.time.

Description

technical field [0001] The invention relates to the technical field of rapid deceleration and stopping of ships, in particular to a ship propeller stern shaft acceleration and deceleration device with simple manufacture, convenient installation, low maintenance cost and simple and reliable operation. Background technique [0002] At present, the navigation safety and operational flexibility of ships are getting more and more attention, especially for ships sailing in inland waterways. Due to the narrow inland waterway and many bends, how to make the ship quickly slow down and stop the ship in case of emergency is the key to avoid The key to accidents is that for most ships with gear boxes with reverse and car clutches, the propeller will work under no load for a period of time after the car clutch is disengaged during the process of changing from car to car. In the state of the water turbine, it is in the high-speed area, and the reverse clutch cannot be combined, so that th...

[0002] At present, the navigation safety and operational flexibility of ships are getting more and more attention, especially for ships sailing in inland waterways. Due to the narrow inland waterway and many bends, how to make the ship quickly slow down and stop the ship in case of emergency is the key to avoid The key to accidents is that for most ships with gear boxes with reverse and car clutches, the propeller will work under no load for a period of time after the car clutch is disengaged during the process of changing from car to car. In the state of the water turbine, it is in the high-speed area, and the reverse clutch cannot be combined, so that the propeller cannot reverse the braking of the ship in an emergency, resulting in longer sailing distance and time, especially for ships with larger tonnage, due to large inertia, The inertia of the stern shaft of the propeller is also large, and its sailing distance and time are longer, which is more likely to cause ship collision accidents
