Description

Solar energy quartz clock with ultracapacitor

Technical field

The utility model relates to a kind of solar energy quartz clock, and particularly a kind of is the solar energy quartz clock of energy storage device with the ultracapacitor.

Background technology

Crystal clock is because of its punctual timing, elegant in appearance, moderate being widely used.It is fit to hang on the wall in room and is used for instruction time very much, brings convenience for people's life.

The manufacturing technology of existing crystal clock, still generally adopt dry cell power supply (as a joint No. five or No. seven dry cells),, also need to change battery about general half a year or 1 year though the power consumption of crystal clock is very low, reach crystal clock more than 10 years for bulk life time, battery is still calculated easily-consumed products.When forgetting when in time more renewing battery, crystal clock is correct instruction time just, even causes damage.For family have only the old man the time, climb and go up the low battery inconvenience especially of changing.

At the problems referred to above, Chinese patent " the quartzy reserve battery of no knob " number of patent application " 98226582.4 " proposes a kind of reserve battery, i.e. design is put at a kind of annular battery of Quartzcrystal watch movement annular space.Purpose is to increase battery capacity, to improve battery serviceable life.This design has its ingenious part, can't but be a kind of selection.But this method be at the wrist-watch occasion, the capacity that increases battery for crystal clock still can not cover the whole life cycle of crystal clock, if battery capacity is continued to increase, to cause cost to increase, and the storage life of battery can not reach and the same life-span of crystal clock, still has the inconvenience that needs to change battery.

The utility model content

Technical problem to be solved in the utility model provide a kind of simple for structure, reliable operation, life-span long, non-maintaining, need change the solar energy quartz clock with ultracapacitor of battery never.

In order to solve the problems of the technologies described above, a kind of solar energy quartz clock that the utility model provides with ultracapacitor, comprise battery, energy storage device, isolating diode, quartz clock movement and shell, described battery is a solar cell, and described solar cell is installed on the described shell, and described energy storage device is a ultracapacitor.

Described solar cell is monocrystalline silicon, polysilicon, organic thin film solar cell plate or solar film battery.

Described ultracapacitor is double layer capacitor, electrochemical capacitor or mixed capacitor.

Described quartz clock movement is pointer quartz clock movement or liquid crystal display formula quartz clock movement.

Adopt the solar energy quartz clock with ultracapacitor of technique scheme, because battery is a solar cell, and solar cell is installed on the shell, and energy storage device is a ultracapacitor.Ultracapacitor is a kind of novel energy-storing device that occurs in recent years, and its capacity can reach farad level even thousands of farad, than the big several magnitude of traditional electrical electrolysis condenser capacity.It has the advantage that conventional capacitor power density is big, the rechargeable battery energy density is high concurrently, but fast charging and discharging has the advantages that capacity is big, leakage current is little, and the life-span reach more than 10 years, can with the same life-span of crystal clock.

The utility model combines solar cell with ultracapacitor, constitute electric energy storage system, supplies with crystal clock and uses, and solar cell produces electric energy and supplies with quartz clock movement when by day light being arranged, and charges to ultracapacitor simultaneously; When night during dull thread, power to quartz clock movement by ultracapacitor, satisfy the work requirements of crystal clock.

In sum, that the solar energy quartz clock that the utility model proposed has is simple for structure, reliable operation, life-span are long, non-maintaining, need change the advantage of battery never, is fit to very much family, outdoor use.

Fig. 2 is the circuit theory diagrams of the utility model solar energy quartz clock.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Circuit theory diagrams of the present utility model as shown in Figure 2.Solar panel or thin-film solar cells 1 are fixed on the panel or shell of crystal clock 4, are connected with ultracapacitor 3 both positive and negative polarities respectively by the both positive and negative polarity of isolating diode 2 with solar cell, and the both positive and negative polarity of ultracapacitor 3 connects the both positive and negative polarity of crystal clock 4.Solar cell 1 is monocrystalline silicon, polysilicon, organic thin film solar cell plate or solar film battery.The quartz clock movement of crystal clock 4 is pointer quartz clock movement or liquid crystal display formula quartz clock movement.Ultracapacitor 3 is double layer capacitor, electrochemical capacitor or mixed capacitor.

When using first ready-made solar energy quartz clock has been placed the light place, allowed solar cell 1 give ultracapacitor 3 chargings, when being charged to the 1V left and right sides, quartz clock movement is promptly started working.Ultracapacitor 3 was to solar cell 1 back discharge when the isolating diode 2 among the figure was used to prevent dull thread.

The principle of work of double electric layers supercapacitor as shown in Figure 1,5 is collector, 6 is the charcoal particle, 7 is barrier film, 8 is ion, when metal electrode inserts in the electrolytic solution, net charge on the electrode surface and the formation of the charged ion in solution electrostatic double layer.Because have a barrier potential on the interface, two layer charges can not be crossed the border and neutralize each other, will form a plate condenser according to the capacitor principle.Because activated carbon surface is long-pending huge, and the electrostatic double layer thickness that forms has only several dusts, tens little to hundreds of dusts more than general electrolytic condenser oxide film.Therefore, double layer capacitor can obtain the capacity of farad level.

Referring to Fig. 2, if element among Fig. 2 is carried out following selection: (Φ 12 * 27mm) for solar panel 50 * 60mm, isolating diode 1N4148, ultracapacitor 2.7V10F, after ultracapacitor was full of electricity, under unglazed condition, crystal clock still can be worked more than 16 hours through actual measurement.Therefore do not wait the electric energy consumption that ultracapacitor filled intact, it is just bright, and solar cell can charge to ultracapacitor again.Can certainly be as required, the working time of crystal clock when further improving dull thread by the capacity that increases ultracapacitor.

That the solar energy quartz clock that the utility model proposes has is simple for structure, reliable operation, life-span Long, non-maintaining, need change the advantage of battery never, be fit to very much family, outdoor use.
