Electronic coaxial master controller of ship

Abstract

The invention discloses an electronic coaxial master controller of a ship. The electronic coaxial master controller comprises a control terminal, a base shell, a mounting plate, a transmission shaft, a wide synchronous belt pulley, a narrow synchronous belt pulley, a servo motor, a potentiometer, a switching value part, a microswitch matched with the switching value part, and a driver controlling the servo motor. A motor shaft belt pulley is fixed on the servo motor, a potentiometer belt pulley is fixed on the potentiometer, the motor shaft belt pulley is connected with the wide synchronous belt pulley, and the potentiometer belt pulley is connected with the wide synchronous belt pulley; the microswitch is mounted on the other side of the mounting plate, a communication end of the control terminal is connected with a signal input end of the controller driver, a signal output end of the microswitch is connected with the communication end of the control terminal, a communication end of the potentiometer is connected with the communication end of the control terminal and a control end of a main propeller of the ship respectively, and the control terminal is provided with a control bus connector. The electronic coaxial master controller is stable in transmission and convenient to operate, transmission reliability and stability are greatly improved, and service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of electrical control of a ship main engine, in particular to a ship electronic coaxial master controller. Background technique [0002] At present, as my country's shipbuilding industry enters a rapid development track, the scale of the industry continues to expand, and the output of shipbuilding is increasing rapidly. The number of shipbuilding completions, new orders received, and orders in hand have been at the forefront of the world for many years in a row. my country has become a major shipbuilding country in the world. However, while the shipbuilding industry is developing at a high speed, the capability of independent innovation is not strong, and the development of marine supporting equipment is lagging behind, especially in terms of ship control instruments and meters, which basically rely on imported related equipment. The electronic coaxial master controller is an important control device in the ...

Problems solved by technology

According to the current survey and analysis of the ship market, the electronic coaxial master controller has just started abroad. It is mainly composed of several large parts such as the shell, transmission parts, custom motors and communication modules. The transmission parts are driven by metal sprockets and chains. The structure (mainly including sprockets, chains and corresponding tensioning idlers), the disadvantage is that the transmission parts of this type of controller are too complicated, and the customization of the motor (the motor specially customized and developed according to the size and function) requires secondary development, maintenance and repair. a lot of inconvenience

And its price is very expensive compared with the price of general instruments and meters. The order cycle is very long, which increases the cost and is very time-consuming. At the same time, because the chain is relatively hard, a slight deviation in the transmission process will cause abnormal noise and stagnation. Its reliability and Poor stability and short service life, this actual situation is very unfavorable to the long-term development goals of my country's shipbuilding industry
