boat propeller

Abstract

Provided is a propeller hanging machine for a ship, comprising a housing, a bracket, a motor, a main shaft, a control handle assembly, an output device and a controller, wherein the motor and the controller are fixedly connected in the housing; the output device is connected to the housing; the motor is connected to the output device by the main shaft in a transmission mode; and the control handle assembly is connected to the housing. The control handle assembly comprises a rotation handle, a connection handle, a connection rod and a potentiometer, wherein one end of the connection handle is fixedly connected to the housing; one end of the rotation handle is sleeved on the periphery of the other end of the connection handle; one end of the connection rod is fixedly connected to the rotation handle; and the potentiometer is connected to the connection handle and is electrically connected to the controller. The propeller hanging machine further comprises a water pump, wherein the motor is provided with a cooling channel, the controller is provided with a cooling channel, and a cooling system is formed by the cooling channel on the motor, the cooling channel on the controller, the water pump and a connection pipeline. The present invention has the advantages of simple structure, high reliability and simple and convenient installation and maintenance, and will not cause the motor and controller to be burnt out even if a ship is backed up for a long time.

Description

technical field [0001] The invention relates to a marine oar hanger. Background technique [0002] At present, if the motor and controller of the traditional propeller hanger are not cooled during operation, the motor and controller will heat up, causing the motor and controller to burn out. Usually, the motor and controller are cooled by water cooling, as described in patent 200810195977.8. The patented water-cooled motor is connected to the main shaft, and the main shaft is used to provide power to control the water flow to cool the motor and controller. However, when the ship reverses, the motor will reverse, and the water will not be sucked into the motor and controller. If it lasts for a long time Reversing the time will cause the motor and controller to burn out. [0003] At present, the control handles of most paddle machines use mechanical transmission to control the speed of the motor boat through sensors when controlling the speed, and when reversing, they also us...

[0002] At present, if the motor and controller of the traditional propeller hanger are not cooled during operation, the motor and controller will heat up, causing the motor and controller to burn out. Usually, the motor and controller are cooled by water cooling, as described in patent 200810195977.8. The patented water-cooled motor is connected to the main shaft, and the main shaft is used to provide power to control the water flow to cool the motor and controller. However, when the ship reverses, the motor will reverse, and the water will not be sucked into the motor and controller. If it lasts for a long time Reversing the time will cause the motor and controller to burn out

[0003] At present, the control handles of most paddle machines use mechanical transmission to control the speed of the motor boat through sensors when controlling the speed, and when reversing, they also use the reversing cable control sensor to drive the motor to reverse. This structure is relatively Complicated, poor reliability, cumbersome installation and maintenance
