Description

The sunflower-type solar energy street lamp

Technical field

The utility model belongs to the illuminating lamp field, relates to a kind of solar street light.

Background technology

At present, known solar street light structure is a solar panel by solar module, the protection of solar energy special charging controller super-charge super-discharge, and light controlling device, batteries, inverter, electricity-saving lamp, lamp bracket is formed.Utilize solar energy generation technology, charged a battery by the solar module generating daytime, the utilization automatic illuminating apparatus, and give street lamp power supply, road lamp power supply evening, is used for throwing light on.

But; though the solar module of existing solar street light device can adjustable plate towards positive elevation angle; but can't follow the position of sun direction; and do not have effective protective device to battery component; causing surfaces of cell to be covered by dust can't efficiently radiates heat, and rainwater can't farthest improve the generating rate to its long-term sour corrosion; also greatly reduce simultaneously the useful life of solar module, and very likely damage battery component owing to falling object from high altitude impacts.

The utility model content

In order to overcome the problems referred to above that existing solar street light exists; the utility model provides a kind of new solar street light; the sunflower-type that solar module is done two kinds of different modes is simultaneously followed solar shaft and is rotated to circumference; can not only normal illumination; and can improve the generating rate greatly; the protection battery component strengthens the lines visual effect simultaneously.

To achieve these goals, the utility model sunflower-type solar energy street lamp, comprise solar module, solar energy special charging controller, batteries, inverter, lamp bracket, electricity-saving lamp combination and circuit, level of solar battery group is installed on the lamp bracket top, and one vertically is installed on the lamp bracket top; At lamp bracket a tumbler is installed also, tumbler inside is equipped with electronic clock, a roller gear and a conical gear are installed on the hour hands rotation axis of electronic clock, a dwang is respectively arranged on two battery pack, on the moving bar of pavilion gear is installed, gear on the dwang is meshed with gear on the electronic clock respectively, and the number of teeth of the gear on the dwang is 2 times of the gear number of teeth on the electronic clock rotation axis with its engagement.

As the further improvement of sunflower-type solar energy street lamp of the present utility model, the circuit aspect, solar module links to each other by solar energy special charging controller and batteries are anodal, and batteries, control switch and electricity-saving lamp are formed lighting loop.The batteries both positive and negative polarity respectively with the battery component tumbler in the electronic clock battery plus-negative plate be connected in addition by transformer, but the also electronic clock of select tape transformation charge and discharge device, make between electronic clock battery charge and electronic clock mechanical movement and form parallel circuits, decompression back is formed the electronic clock mechanical rotation and is put the charging synchronization loop night.The control end of control switch links to each other with solar module is anodal, the high and low level of control end is in switch respectively and closes and open two states, daytime, solar module generating and the charging of accumulators group, night, the control switch closure, the batteries power supply provides illumination, and promptly control switch is connected lighting loop.

In above-mentioned circuit, can increase the illuminating line of conventional street lamp, in emergency circumstances use conventional power supply illumination.

Further improvement as sunflower-type solar energy street lamp of the present utility model, in the solar module front transparent toughened glass spherical crown can be installed, and can be in the transparent coatings of the inboard Coating tape gain effect of this toughened glass spherical crown, fairshaped plastics air bell is installed at the solar module back side simultaneously, with the spherical crown bound fraction be the ball arc, open air-vent at air bell and tumbler bound fraction.

Dynamo-electric in conjunction with the aspect, because being in sunflower-type constantly, solar module rotates, electric wire can't be directly with itself and solar energy special charging controller thereupon reversing, the batteries connection.Select to install two brushes, carry the rotation electric wire of the stream that conducts electricity under the battery component to be connected, be circulated to special charging controller and batteries positive pole through under the securing electric lines again with brush.

The beneficial effects of the utility model are: solar battery group can be rotated with the variation of position of sun, and the extinction ability strengthens.Transparent coatings itself can make the light-absorbing and electricity-generating rate of solar module increase more than 1.5%, and the electric power that consequent electric power can satisfy electronic clock replenishes, and has avoided the part consumption to the solar module generating.Transparent toughened glass spherical crown makes solar module avoid the sour corrosion of direct impact of falling object from high altitude and rainwater, simultaneously, toughened glass spherical crown and open and form a bigger space between the streamlined plastics air bell of pore, help solar module surface heat transmission and heat radiation, reduce the ratio that luminous energy is converted into heat energy, improved the ratio that luminous energy is converted into electric energy.The toughened glass spherical crown can also be resisted high wind with streamlined combination of air bell.The solar module that two kinds of different modes sunflower-types rotate is compared existing fixed solar module, absorption efficiency that can bigger raising solar energy, thus bigger raising generating rate prolongs lighting hours.And, make solar street light in case of emergency can use conventional power supply with combining of conventional power supply.Also can directly on existing street lamp, reequip, save the waste of cost and goods and materials.Simple in structure, lines are aesthetic in appearance, and are dynamic strong.
