Description
Technical Field
The utility model is applied to the technical field of ship accessories, and particularly relates to a multi-host startup storage battery connection structure.
Background
In recent years, diesel engine generator sets are increasingly used in ships, and are also increasingly widely used for electric propulsion besides conventional ship power supply sets, and due to the unique advantages of the diesel engine generator sets, full or half electric propulsion is a development trend of ship propulsion systems of thousands of tons or more, especially military ship propulsion systems, and diesel engines are mainly used as prime movers of ship generator sets. The starting modes of the diesel engine are generally three types: manual starting: the crank and the flywheel are directly rotated by manpower by means of a crank and a rope, so that the diesel engine is started, and the method is the simplest starting method; starting compressed air: compressed air with higher pressure enters the cylinders according to the firing sequence of each cylinder of the diesel engine, and the compressed air expands in the cylinders to push the pistons to move and drive the crankshafts to rotate so as to realize the starting of the diesel engine; starting the motor: the starting motor is used for driving the crankshaft of the diesel engine to rotate by taking electric energy as energy, so that the diesel engine is started.
The starter motor is a motor that converts electric energy into mechanical energy, and a low-voltage (12V or 24V) dc motor is generally used as a power machine for starting a diesel engine. The electric starting system comprises a storage battery, a starting motor, a charging generator, a regulator and the like.
When the ship is provided with a plurality of electric starting diesel generator sets, independent electric starting systems are adopted respectively, and when a certain generator starts the storage battery, the electric quantity is insufficient or damaged, the generator cannot be started.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provides a multi-host startup storage battery connection structure which can conveniently switch the power supply of other storage batteries when one group of storage batteries is in failure.
The technical scheme adopted by the utility model is as follows: the utility model comprises at least two starting units, each starting unit comprises a starting motor and a group of storage batteries, and the starting motors are electrically connected with the storage batteries through lines, and the utility model is characterized in that: all be provided with the switch transfer box on the circuit of every unit, switch transfer box inside is provided with change over switch, change over switch includes movable part, fixed part and two connecting portion, the one end of movable part with the fixed part is connected, the other end and two of movable part connecting portion selectivity cooperation, the fixed part with starter motor electric connection, two connecting portion respectively with two sets of the battery is connected.
Further, each group of storage batteries is connected with the two switch conversion boxes.
Furthermore, a branch switch is arranged on a circuit between the switch conversion box and the starting motor.
Further, the change-over switch is a double-pole double-throw switch.
Further, the multi-host startup storage battery connection structure further comprises a master controller, wherein the master controller is connected with the double-pole double-throw switch to control the connection state of the movable part and the connecting part.
The utility model has the beneficial effects that: each starting motor is connected with two groups of storage batteries, and when one group of storage batteries is in fault, the other group of storage batteries can be connected through the change-over switch to supply power.
