Abstract
The utility model relates to a solar electric power supply device which is mainly composed of a solar charger, a storage battery protector, storage batteries, and an inverter. The utility model is characterized in that the device uses a main and a standby groups of storage batteries; the main and the standby groups of storage batteries are controlled by a switching circuit for timed charge and electric power supply in turn. As a result, the storage batteries arranged in the device always work in the state of high voltage, the service life of the storage batteries is effectively extended, and the function of solar charge of the electric power supply device is enlarged.
Description
The utility model belongs to a kind of supply unit, specifically the sun-generated electric power machine.
Sun-generated electric power has begun to provide electric power for areas such as mountain area, rural area, field works at present; existing sun-generated electric power mostly is these three parts of solar cell, storage battery and inverter and forms; generally all be to adopt a group storage battery to control level of charge by protective circuit; such mode can not guarantee that this storage battery always works in the high voltage state; be unfavorable for the long-term use of storage battery, and a group storage battery job can not guarantee the power supply uninterrupted power supply.
The purpose of this utility model is intended to overcome deficiency of the prior art, and a kind of sun-generated electric power machine that active and standby two group storage batteries regularly were recharged and provided power supply in turn that has is provided, and makes storage battery always work in the high voltage state.
The purpose of this utility model can be achieved through the following technical solutions.
The utility model mainly is made up of solar charger (1), storage battery protecting device (2), storage battery; solar charger (1) passes through storage battery protecting device (2) to charge in batteries; the direct-flow input end of the positive and negative termination inverter (3) of storage battery; (see figure 1); it is characterized in that: this power machine adopts active and standby two group storage batteries to switch circuit by one and regularly is recharged and provides power supply in turn, and above-mentioned commutation circuit is mainly by 555 time-base circuits, counter and relay J
2Form (see figure 2), wherein 555 time-base circuits are connected into multivibrator, its output connects the trigger end of counter, the output of counter is controlled a miniature relay J by a buffering triode BG
1Break-make, by this miniature relay J
1Drive relay J
2Utilize relay J
2Two groups of contacts be connected into the double-point double-throw switch (see figure 2), two moving contacts of this double-point double-throw switch connect the charging and the current supply circuit of storage battery respectively, and two quiet two end points often opening the back formation that links to each other with two quiet normally-closed contacts separately connect the anode of active and standby storage battery respectively.Adjust the pulse duration of 555 time-base circuits in the commutation circuit before the work earlier, thus the flip-flop transition of decision counter output.During work, to standby battery (4) charging, main storage battery (3) provides power supply to inverter to solar charger through storage battery protecting device, treat a period of time after, counter rollover, relay J
1Action, aforementioned double-point double-throw switch action switches to standby battery current supply circuit automatically, main storage battery is switched to charge circuit, so regularly switches in turn, and active and standby storage battery is recharged and provides power supply in turn.
Advantage of the present utility model as can be seen from the above description:
1, used active and standby storage battery, made storage battery always work in the higher voltage state, prolonged the useful life of storage battery effectively, increased economic efficiency;
2, under special circumstances, can take standby battery separately in other places and be full of electricity after, connect machine again to guarantee the power supply power supply.
3, standby battery interface also can be used as the charging inlet of other storage battery, has enlarged the function of this machine solar recharging.
Fig. 1 is a main circuit diagram of the present utility model,
Fig. 2 is the schematic diagram of commutation circuit.
1-solar charger wherein, 2-storage battery protecting device, 3-main storage battery, 4-standby battery, 5-inverter
Embodiment:
Adopt HC305 * large area amorphous silicon solar cell of 915 types to make solar charger, active and standby storage battery all adopts 6-MX-30 type sealed cell, and inverter adopts WPS220A inversion thick film circuit, relay J
2Adopt the transformation of the way of 552 types.555 time-base circuits adopt the NE555 integrated package, and counter adopts the CD4040 integrated package, and each parts connects and composes by Fig. 1, Fig. 2 possesses the solar charging motor that active and standby storage battery switches.C wherein
1Get 47 μ, be 2 hours the flip-flop transition of counter, and active and standby storage battery switched once in promptly per 2 hours.
