Detailed ways

The utility model provides a power-saving power structure of an electric boat, as shown in Fig. 1, by two or more storage battery groups 10, an electric motor 30 is supplied with power through an electric controller 20 in exchange; the electric motor 30 has a A small generator 31 electrically connected to the power controller 20, and the output shaft 32 is provided with a counterweight flywheel 33, a rotational speed detector 34 and a first rotating shaft 40, a second rotating shaft 50 and a third rotating shaft 60; The first rotating shaft 40 has a first clutch 41 and a steering control box 42, and is matched with a reduction gear set 43 to selectively drive the rotating shaft of the propeller 30; the second rotating shaft 50 has a second clutch 51, And with a gear box 52, selectively and switchably drive the rotating shaft of the propeller 70; the third rotating shaft 60 has a third clutch 61 controlled by the speed detector 34, and the action of the third clutch 61 , to decide whether to drive an alternator 80; the power output terminal of the alternator 80 is connected to a power box 81, and is connected to the storage battery pack 10 after a group of rectifier transformers 82; the output shaft 32 after the motor 30 starts Whether the propeller 70 has been driven, the motion inertia and labor-saving effect of the counterweight flywheel 33 on the output shaft 32 can be utilized, and the rotating speed detection of the output shaft 32 by the speed detector 34 can be used to drive the alternator 80 to generate electricity in due course; While the propeller 70 can save electricity to propel the boat, the excess power of the output shaft 32 is converted through the alternator 80 to generate electricity to charge the storage battery pack 70. In this way, the boat can effectively save power consumption and increase the voyage .

That is to say, when the rotational speed detector 34 detects that the output shaft 32 does not reach a certain rotational speed, it will not control the action of the third clutch 61; The output voltage of the upper small generator 31 is to increase the pulse wave mode, so that the electric motor 30 is gradually increased by the slow speed, so that the output shaft 32 is driven by the electric motor before reaching the rotating speed detected by the rotating speed detector 34. 30 does not need to bear the load from the alternator 80 on the third rotating shaft 60, and because there is no load on the first rotating shaft 40 and the second rotating shaft 50, the output shaft 32 is smoothly linked with the counterweight flywheel 33 to rotate; and After the motor 30 is started, the large torsion generated by the output shaft 32 rotating at high speed with the counterweight flywheel 33 will be generated by the rotational speed when the first rotating shaft 40 and the second rotating shaft 50 are idle without load.

And when the first clutch 41 on the first rotating shaft 40 has (in gear) actuation, and coordinates the switching of steering control box 42, when desiring to make the boat start and move forward or slowly back, the counterweight flywheel 33 on the output shaft 32 of the motor 30 The high-torque power generated by the high-speed gyration is output from the first rotating shaft 40, and then the decelerating torque of the reduction gear set 43 can be increased again to drive the rotating shaft of the propeller 70 labor-savingly, so that the boat starts to slow down in the most power-saving manner. Slowly advance or reverse; and in this process, if the propeller 70 rotating shaft starts, because the initial rotational resistance is too large, and there is an action phenomenon that causes the output shaft 32 rotational speed to decrease instantaneously (at the beginning), the rotational speed detector 34 will stop immediately The action control of the third clutch 61 makes the third rotating shaft 60 immediately stop the power output to the alternator 80, because the power of the output shaft 32 does not need to share the load of the alternator 80, so that the propeller 70 can obtain all the power of the output shaft 32 , to play a good starting rotation performance. And again when the boat starts and moves smoothly, the actuation of the first clutch 41 can be released at this time, and the switching is actuated by the second clutch 51, then the power conversion of the output shaft 32 is output from the second rotating shaft 50, and the speed can be changed by the gear The variable speed operation of the box 52 increases the rotation speed of the propeller 70 and increases the speed of the boat. And regardless of whether the power of the output shaft 32 is output to the propeller 70 by the first rotating shaft 40 or the second rotating shaft 50, as long as the rotating speed of the output shaft 32 reaches or exceeds the speed detected by the rotating speed detector 34, the third clutch 61 will be activated at any time. Recover the action, so that the excess power is automatically distributed to the alternator 80 to generate electricity, and the electricity generated by the electricity is randomly recharged to the storage battery pack 10 for storage and reuse. voyage.
