Description
Affiliated technical field
The utility model relates to a kind of electric supply installation, is the device that the user powers with small-sized solar cell panel and DC power supply particularly.
Background technology
At present, along with requirement on environmental protection, the proportion that utilizes of solar energy is just constantly improved, the exploitation of solar cell and output also constantly increase, and the utilization of solar energy also enters into family gradually.Yet, no matter adopt many advanced solar cells, its influence that is subjected to sunlight is self-evident: solar cell is that the effect of charge in batteries is better when solar radiation is arranged, just can not charge when no sunlight or sunlight are more weak or charging effect bad.At the electric power enterprise that utilizes solar cell power generation on a large scale, because of solar panel is many, the energy energy stored is more, when number of users has in limited time, can satisfy user's need for electricity.But for utilizing solar powered family, because the limited amount of solar panel, the electric energy of its generation just is difficult to satisfy the demands, and particularly when overcast and rainy or sunlight was strong inadequately, the electric weight of storage was not enough to satisfy the need of electricity consumption.
Summary of the invention
The purpose of this utility model, be to provide a kind of for household use, can to utilize two kinds of energy such as solar energy and DC power supply be the device of user's power supply, makes the user when the electric weight of solar energy converting is not enough, also can guarantee normal power supply.
The purpose of this utility model is achieved in that this device comprises solar panel charging circuit 1, DC power supply charging circuit 2, booster circuit 3, and solar panel charging circuit 1 is connected with booster circuit 3 with DC power supply charging circuit 2 backs in parallel; Described solar panel charging circuit 1 is by solar panel A, and diode VD1 and storage batteries D are formed, and the positive pole of the positive pole of solar panel and diode VD1 connects, and the negative pole of diode VD1 and the negative pole of storage batteries D connect, the plus earth of storage batteries D; Described DC power supply charging circuit 2 is by DC power supply B, resistance R 1, LED 1, diode VD2 and storage batteries D are formed, the positive pole of DC power supply with connect with the positive pole of diode VD2 again after resistance R 1 is connected, the negative pole of diode VD2 and the negative pole of storage batteries D connect, storage batteries D is that solar panel charging circuit 1 and 2 two circuit of DC power supply charging circuit are shared, and LED 1 is in parallel with resistance R 1, is used for the charging indication; Described booster circuit 3 is by power switch S1, step-up transformer E, resistance R 2, R3, the NPN triode, diode VD3, capacitor C 1, LED 2 is formed, wherein, R3 and C1 constitute R-C intermittent oscillation circuit 4, be used for the voltage of circuit being raise by the duty ratio that intermittent oscillation changes voltage, output coupled power switch S1 after solar panel charging circuit 1 and DC power supply charging circuit 2 are in parallel, output after step-up transformer E boosts then, C is the output of this device circuit, LED 2 is as output indicator, VD3 is a fast recovery diode, be used for high-frequency rectification, the NPN triode is used to amplify input current for emitting stage connection altogether.
Operation principle of the present utility model is: when sunlight was sufficient, solar panel was the storage batteries D charging by diode VD1 just, is electric energy with solar energy converting, is stored in the storage battery, until saturated.More weak or do not have the solar time when sunlight, DC power supply is a charge in batteries by resistance R 1 and diode VD2.During electricity consumption, the power switch S1 that closes, the characteristic of the quick shutoff (ending) by blocking oscillator realizes boosting, and the voltage of storage battery is after step-up transformer E boosts, for user power utilization.
The beneficial effects of the utility model are: after adopting above-mentioned solar panel and DC power supply to be two charging energy sources devices of charge in batteries, no matter can guarantee strong and weak or have or not under the situation of sunlight at sunlight, all charge in batteries can be, thereby normal power supply can be guaranteed.
Description of drawings
Fig. 1 is the structure principle chart of this device,
Fig. 2 is the circuit structure diagram of this device.
Each Reference numeral is: 1, solar panel charging circuit, 2, the DC power supply charging circuit, 3, booster circuit, 4, the R-C intermittent oscillation circuit.
Embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing 2, but embodiment is not to qualification of the present utility model.
Embodiment, referring to Fig. 2, it is the diode of IN4007 that VD1 and VD2 adopt model, and VD3 is a fast recovery diode, and model is IN5819; It is 8050 that the NPN triode adopts model.It is the resistance of 1W that R1 selects power for use, and when R1 was 10 Ω, the optimal external charging voltage was 3～4V, and LED1 is the external charging indicator light, and it is to utilize the pressure drop on the resistance R 1 to light.Among the figure, A is a solar panel, and when sunlight was sufficient, solar cell was a charge in batteries, and until saturated, B is a DC power supply, and when no sunlight, DC power supply is a charge in batteries, and C is the output of this device.S1 is a power switch, and booster circuit is started working after the S1 closure, and storage battery just can drive load.
