Description
Technical Field
The invention belongs to the technical field of ship construction, and particularly relates to a master control device of a low-gear-shifting-interval electric anchor machine and a control method thereof.
Background
The electric anchor has the advantages of simple structure and low maintenance requirement, and is widely applied to modern ships. In order to adapt to different anchoring working conditions, the electric anchoring machine is generally provided with forward and reverse rotation, high, medium and low three-gear rotating speeds, and has electromagnetic brake to prevent the gravity of an anchor chain from falling down in neutral position. The above operations are all sent by the anchor master controller, wherein the cam master controller is most widely used. The cam type controller rotates through the cam to push the supporting rod, the supporting rod drives the movable contact to rotate, when the movable contact contacts with the fixed contact, a current closed contact instruction can be sent, and switching between different gears can be achieved through rotating the cam. But it has shortcomings in the operation, as will be described below in connection with fig. 1-6.
The cam a can rotate around the rotating shaft h, the supporting rod d drives the contact c on the supporting rod to rotate when rotating around the rotating shaft e, and when the moving contact c contacts with the fixed contact b, the contact is closed, namely, a command is sent.
In the process of switching the low-speed anchor receiving operation mode to the medium-speed anchor receiving operation mode, namely, a process of rotating the cam a by 90 degrees clockwise, when the cam a rotates from 0 degrees to alpha degrees, the low-speed gear contact is closed, the medium-speed gear contact is opened, the controller is mainly caused to send a low-speed anchor receiving instruction, and the motor is electrified, as shown in fig. 1-2; when the cam a is rotated from alpha to 90-alpha, the low-speed gear electric shock is disconnected, the medium-speed gear electric shock is disconnected, the main command controller does not send out a command, and the motor is powered off, as shown in figure 3; when the cam is rotated from 90 DEG to alpha to 90 DEG, the low-speed gear contact is opened, the medium-speed gear contact is closed, the main controller sends out a medium-speed anchor receiving instruction, and the motor is electrified again, as shown in figures 4-5.
A timing diagram of the cam type master controller shift process is shown in fig. 7.
Through analyzing the working conditions, the controller does not send out instructions for a long time in the gear switching process, the motor is powered off, the system loses tension, the anchor chain and the anchor can freely fall under the action of self weight, and the phenomenon of 'slipping anchor' which is quite dangerous occurs. When the gear is switched to the next gear, the main controller gives out a command again, the motor is electrified again, the motor is reversed against the falling motion of the anchor chain and the anchor, and at the moment, extremely high current peaks are generated to influence the service life of the contactor. If the peak current is too large, the power switch is caused to overcurrent and trip, the system loses power and cannot work normally, and potential safety hazards are brought.
