A kind of portable power source device of practicality
The utility model is related to a kind of new electric power systems, and in particular to a kind of portable power source device of practicality, it is especially suitable
For the power supply of the industries handheld devices such as building and emergency lighting power supply system.
It is mainly three-level distribution system in the power supply that site operation at this stage uses, three-level distribution system fixed point provides, spoke
It penetrates that area is small, takes that electrical distance is remote, supply port position is lacked, and causes work progress electricity consumption inconvenient, the shortcomings of electricity shortage, and safety
Hidden danger is larger.For current condition of construction, when construction, takes electric security risk mainly to have the following：
1. take electrical distance remote and caused by power cord breakage, insulation ag(e)ing, connector it is more, it is anxious easily to form electric leakage, short circuit initiation
2. electric wire arbitrarily draws, connects up and messy mix, is soaked, answering overhead both aerial or do not take guarantor during onsite application
Shield measure, and puncture is crushed by weight or sharp objects thorn；
4. it disorderly connects, not by hypertelorism between standard operation and distribution box and equipment privately, more than 5m.
It 5. two stage electric power system is incomplete, takes electric port few, is easy to cause a lock multimachine, causes short circuit risk.
The content of the invention
The utility model provides a kind of mobile power of practicality to overcome the above-mentioned problems of the prior art and shortcoming
Device, can be moved to according to construction site actual conditions any one needs position, and construct it is convenient, flexible, continuation of the journey when
Between the advantages such as long.Can be all handheld tool power supplies used in scene, including：Electric hammer, electric pick, electric hand drill, hand mill,
The equipment such as water dispenser, kettle in LED illumination lamp and life, the present apparatus also have energy-saving and environmental protection, beauty, safety etc.
Technical solution is used by the utility model solves its technical problem：
A kind of portable power source device of practicality, if including dry battery, inverter current compensator, cart, distribution box, it is special
Sign is：All accumulators, inverter current compensator, distribution box are separately fixed on cart, after the series connection of all accumulators with it is inverse
Time-dependent current compensator is connected, inverter current compensator access distribution box, will be straight by inverter current compensator after accumulator series connection
Galvanic electricity switchs to alternating current, and alternating current is exported by distribution box.
The utility model further includes earth leakage protective device, and earth leakage protective device is mounted on cart, and earth leakage protective device and inversion
After current compensator is connected, then export alternating current.
The utility model further includes LED illumination lamp, and LED illumination lamp is mounted on cart, and LED headlamps pass through switch
Circuit is connected into each accumulator.
Knob is equipped with above the cart, bottom is set there are two translation wheel, and each translation wheel is equipped with antiskid claw.
The utility model device have design rationally, make that simple, work efficiency is high, energy conservation and environmental protection and improves scene and applies
The convenience and security of work electricity consumption.The characteristics of the utility model construction is flexibly convenient, security performance is strong, environmentally protective, is suitble to
Various industries are constructed and life is practical.
Description of the drawings
Fig. 1 is the utility model circuit connection diagram.
The side schematic view of Fig. 2 the utility model.
The utility model is further described with reference to attached drawing.The inverter current compensator of the utility model, distribution box, leakage
Non-electricity protector is existing structure, is directly commercially available from market.
As shown in Figure 1 and Figure 2, the utility model includes accumulator 1, inverter current compensator, the cart of four 12V-20AH
3rd, distribution box, earth leakage protective device, LED illumination lamp 2, it is characterised in that：Four accumulators 1, inverter current compensator, distribution box,
Earth leakage protective device, LED illumination lamp 2 are separately fixed on cart 3, are connected after four accumulator series connection with inverter current compensator,
Inverter current compensator accesses distribution box after being connected with earth leakage protective device, pass through inverter current compensator after four accumulator series connection
Direct current is switched into alternating current, alternating current is exported by distribution box；And LED headlamps 2 are connected by switching with each accumulator
Into circuit.3 top of cart is equipped with knob, and bottom is set there are two translation wheel 4, and each translation wheel 4 is equipped with antiskid claw.It is inverse
Time-dependent current compensator, distribution box are to be grounded, and for LED illumination lamp 2 for illuminating, cart 3 is easy to remove.The utility model
DC conversion by inverter current compensator directly into alternating current is exported up to voltage range and reached by 12V-20AH accumulators simultaneously
220v-2000w peak values.Inverter current compensator (generally 220V, 50Hz sine waves).
