boat propeller

Abstract

The invention provides a marine propeller machine, which includes a casing, a bracket, a motor, a spindle, a control handle assembly, an output device and a controller. The motor and the controller are fixedly connected in the casing, and the output device is connected to the casing. , the motor is connected to the output device through the main shaft, and the control handle assembly is connected to the casing. The control handle assembly includes a rotating handle, a connecting handle, a connecting rod and a potentiometer. One end of the connecting handle is fixedly connected to the casing, and the rotating handle is fixedly connected to the casing. One end is placed on the outer periphery of the other end of the connecting handle, one end of the connecting rod is fixedly connected to the rotating handle, the potentiometer is connected to the connecting handle, and is electrically connected to the controller; it also has a water pump, a cooling channel on the motor, and a cooling channel on the controller. There are cooling channels. The cooling channels on the motor, the cooling channels on the controller, the water pump and the connecting pipelines form a cooling system. The invention has simple structure, good reliability, easy installation and maintenance, and will not cause the motor and controller to burn out even if the ship reverses 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
