Abstract
The utility model discloses a rain drops electricity generation solar street lamp, include lamp pole and the lamp holder of fixing with the lamp pole solar panel is installed on the top of lamp pole the controller that is coupled with solar panel is installed to the lamp pole bottom, the controller is coupled with battery and lamp holder respectively one side of the relative sky of solar panel is covered and is had the piezoelectric membrane, and implant the piezoelectricity electrode in the piezoelectric membrane, the piezoelectricity electrode is coupled with the controller. The utility model discloses aim at in, adopt the piezoelectric membrane to cover on solar panel through the technique, not only can normally receive the solar radiation energy, can also receive rain drops mechanical energy on rainy day and acquire the energy jointly. Also can maintain rain drops electricity generation solar street lamp's work like this on long -time lasting rainy day.
Description
Technical field
The utility model relates to a kind of street lamp, relates more specifically to a kind of raindrop power generation solar street lamp.
Background technology
Existing solar street light is comparatively large by such environmental effects such as geography, weathers, and because it mainly relies on the sun to provide the energy, so local geography and climate weather conditions directly can have influence on the use of solar street light.Especially China some areas, often there will be the rainy weather of continuous more than a week and even two weeks, and rainy weather, after affecting sun energy circuit for a long time, causes its brightness not reach the requirement of national standard.
Meanwhile, solar street light also can be not enough because of daylight, and the time causing evening bright is too short, components and parts service life and cost performance low.In China some areas in order to overcome above-mentioned defect, the solar street light of this area all adopts civil power dual power supply mode, then its management and maintenance is very difficult, Expenses Cost.
Summary of the invention
The purpose of this utility model overcomes or slow down the part at least above-mentioned shortcoming, a kind of solar street light is provided hereby, comprise lamp stand and the lamp holder fixing with lamp stand, on the top of described lamp stand, solar panels are installed, the controller coupled with solar panels is installed bottom described lamp stand, described controller couples with battery and lamp holder respectively, piezoelectric membrane is covered with in the side of the relative sky of described solar panels, and being implanted into piezoelectric electrode at described piezoelectric membrane, described piezoelectric electrode and controller couple.
Preferably, described piezoelectric membrane selects pvdf membrane.
Preferably, described solar panels relatively face tilt 15 to 30 degree.
The utility model is intended to, and adopts piezoelectric membrane to cover on solar panels by technology, not only normally can receive solar radiation energy, can also receive raindrop mechanical energy jointly obtain energy on rainy day.Continuing the work that also can maintain solar street light rainy day for a long time like this.
Accompanying drawing explanation
Describe these and other aspect of the present utility model in further detail now with reference to appended accompanying drawing, it is depicted as currently preferred embodiment of the present utility model.Wherein:
Fig. 1 is the structure chart of the utility model solar street light.
In figure: 1, lamp stand; 21, knee; 22, street lamp; 3, solar panels; 4, piezoelectric membrane; 5, device of solar generating.
Detailed description of the invention
Below in conjunction with accompanying drawing and instantiation, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
A kind of solar street light 22, comprises lamp stand 1 and lamp holder, and lamp holder extends to outside by knee 21.Be provided with at the top of lamp stand 1 towards skyward solar panels 3, be provided with bottom lamp stand 1 and gather the energy-producing device of solar generating 5 of solar panels 3, device of solar generating 5 comprises controller and battery.
The effect of the controller of the present embodiment is the duty controlling whole solar street light 22, and battery is played to the effect of additives for overcharge protection, over.In the place that the temperature difference is larger, qualified controller also should possess the function of temperature-compensating.Other additional functions such as light-operated switch, time switch should be all the options of controller.
Battery: generally select lead-acid battery, also optional Ni-MH battery, nickel-cadmium cell or lithium battery.Its effect be when there being illumination by the electrical power storage that solar energy energy plate sends, when controller calls, discharge.
Solar panels 3 are connected with controller by the circuit of lamp stand 1 inside, and controller is connected with battery.The energy via controller so produced via solar panels 3 enters battery and stores.Meanwhile, the energy that controller can call in battery works for street lamp 22.
The present embodiment is covered with piezoelectric membrane 4 in the side of the relative sky of solar panels 3, and implants piezoelectric electrode in piezoelectric membrane 4, and piezoelectric electrode and controller couple.Due to, when piezoelectric membrane 4 is out of shape when the effect being subject to external force mechanical energy, electric charge can be produced; So, when raindrop shoot down on piezoelectric membrane 4, piezoelectric membrane 4 can due to deformation produce electric charge, and produce electric charge collected by piezoelectric electrode after, via controller is stored in battery, for generating.
Preferably, the piezoelectric membrane 4 of the present embodiment selects the pvdf membrane of 25 micron thickness, and when the raindrop that diameter is 1 to 5 millimeter shoot down on pvdf membrane, raindrop can cause the vibration of pvdf membrane, can produce electric charge with that.Now, charge-trapping will get up by piezoelectric electrode, for generating.Raindrop volume is larger, and the vibration brought must be larger, and the electric charge of generation is also more.Root is estimated, the raindrop of maximum volume at least can generate electricity 1 microwatt.
Preferably, the solar panels 3 of the present embodiment relatively face tilt 15 to 30 degree.So, raindrop shoot down after on pvdf membrane, along the tilt flat plate landing of solar panels 3, raindrop can be avoided to put aside on solar panels 3, affect the impact of follow-up raindrop to pvdf membrane.
