Abstract
An energy-saving device for generator power conversion of rubber-tired transtainer is disclosed. Besides one original large-power AC power generator connected in internal combustion engine of the transtainer for supplying power to the transtainer, a small-power DC power generator is also connected, and sequentially connected with a storage battery, an inverter, a PLC controller, a converter, a diverter switch, and electric appliances for illumination and air conditioning. Under idle state of the transtainer, the AC power generator stops power generation, under power-loss control of the PLC controller, 12-24 V DC power supply generated by the DC power generator or stored by the storage battery is converted into 220 V AC power supply to supply power for other electrical facilities. When the transtainer is under operational state, through the above control system, the AC power generator generates power to supply power for the whole machine, and electric energy of the DC power generator is stored by the storage battery for later use.
Description
Affiliated technical field
The utility model relates to a kind of energy saver of tyred container door type crane generator power conversion.
Background technology
At present, tyred container door type crane generally all adopts Diesel engine to make the 500kW generating set to power supplies such as the operation of tyre crane, illuminations with the rotating speed of 1500r/s.But the practical efficiency of tyred container door type crane loading and unloading operation is about 60%, 40% is mainly shared running time by non-loading and unloading in addition, but in order to guarantee the power supply needs of facilities such as driver's cabin air-conditioning, illumination, have to make engine to keep the rotating speed of 1500r/s to make powerful generating set be in running status, wasted certain energy consumption thus.
Summary of the invention
In order to reduce the energy resource consumption of tyred container door type crane in non-loading and unloading running status, the utility model provides a kind of generator power conversion energy saving device, this device is when non-loading and unloading move, be crane engine when being in idle running (800r/s), being transformed into the low-power generator is other electricity consumption facility powers.
The technical scheme that the utility model technical solution problem is adopted is: the crane explosive motor is except that high power alternator for the crane power supply of former connection, connect a low power DC generator again, connect a lower powered DC generator at crane engine, and part electrical appliances such as the storage battery that is linked in sequence, inverter, change over switch and illumination air-conditioning.When crane is in non-loading and unloading running status, by the electric control of PLC disabling controller, transducer and diverter switch, and connected the inverter that makes direct current convert alternating current to down, making DC generator is that illumination waits electrical appliance to power.When crane transferred the loading and unloading running status to, when promptly crane engine was in work running (1500r/s), by above-mentioned control system, the alternating current generating sets generating was complete machine operation power supply, and the electric energy of DC generator is by battery stores.
The beneficial effects of the utility model are: make power supplies such as the driver's cabin air-conditioning of tyred container door type crane when non-loading and unloading running status, illumination, be converted to the low-power generator by the high power generation machine, saved energy consumption thus.
