The utility model can make full use of the reproducible energy to generate electricity and charge the storage battery via the arranged wind-power generator and the wind-power electricity-generated charging controller, the solar energy battery plate and the solar energy charging controller. The solar energy and the wind generate the electricity in the sunny days, while the wind power generates the electricity at night or in the rainy days. In this way, the wind power and solar energy plays a complementary role in generating electricity so as to guarantee the normality and continuity of the street lamp to work. The arranged commutation switch not only can provide the direct-current power, but also provides the alternating current power. The utility model has the advantages of making full use of the reproducible energy, the simple structure, having strong practicability and popularization and can be widely used for illuminating the city and countryside road.

Description

Wind-solar hybrid street light

technical field

The utility model relates to a wind-solar complementary street lamp, which is used for lighting public places such as roads, squares, schools and residential areas, and belongs to the technical field of lighting fixtures.

Background technique

With the continuous and rapid development of social economy, energy contradictions are inevitably placed in front of people. As urban and rural roads, squares, docks, schools, residential areas and other public places, the contradiction of lighting energy is particularly prominent. Using solar power and wind power to alleviate energy conflicts has become a research topic all over the world. At present, the existing technical solutions using solar lighting and wind power generation lighting can only use DC bulbs such as energy-saving lamps, LEDs, and high-frequency electrodeless lamps. Street lamps cannot meet the requirements of high-power road lighting.

Contents of the invention

The purpose of this utility model is to meet the maximum utilization of two energy-saving resources of solar power generation and wind power generation, according to the actual needs of users, select DC or AC power supply mode to ensure the needs of road lighting, and provide a new wind-solar complementary street lamp. At the same time, in order to ensure the aesthetic performance of the street lamp, a breeze generator is selected to generate electricity, and the battery and inverter are placed under the foundation.

The purpose of this utility model is achieved through the following technical solutions, a wind-solar complementary street lamp, including light bulbs, lamps and light poles, characterized in that the street lamp is also equipped with wind power generators, wind power charging controllers, solar panels, Solar charge controller and storage battery, transfer switch, inverter, wind power generation charge controller, output of solar charge controller connected to storage battery, indirect transfer switch between output of storage battery, inverter and set DC load, wind generator, Solar panels are fixed to light poles.

One end of the transfer switch is a DC output, connected to a DC light bulb and other loads, and the other end of the transfer switch is output to an inverter, connected to an AC light bulb and other loads.

The wind power charge controller, solar charge controller, battery and inverter are placed in the foundation of the light pole.

The utility model can make full use of the renewable energy to generate electricity and charge the storage battery by setting the wind power generator, the charging controller for wind power generation, the solar panel and the solar charging controller at the same time. It can be powered by solar energy and wind power in sunny days, and by wind power in cloudy and rainy days and nights. Power generation plays a complementary role to ensure the normality and continuity of street lamp work. By setting a switch, it can provide both DC power and AC power. The utility model makes full use of renewable energy, has a simple structure, and has great advantages Strong practicability and promotion, can be widely used in urban and rural road lighting.

Description of drawings

Fig. 1 is a block diagram of the utility model;

Fig. 2 is a structural representation of the utility model;

In the figure, 1 wind power generator, 2 wind power generation controller, 3 solar panel, 4 solar power generation controller, 5 storage battery, 6 transfer switch, 7 inverter, 8 DC bulb, 9 AC bulb, 10 lamp, 11 lamp pole.

Detailed ways

Further illustrate the utility model in conjunction with accompanying drawing and embodiment, the utility model is made up of wind power generator 1, wind power generation controller 2, solar panel 3, solar power generation controller 4, storage battery 5, transfer switch 6, inverter 7, A direct current light bulb 8 or an alternating current light bulb 9, a lamp 10, and a light pole 11 form. Wind power generator 1 converts wind energy into electrical energy, wind power generation controller 2 has overcharge and over discharge protection technology for storage battery 5, solar panel 3 converts sunlight energy into electrical energy, solar power generation controller 4 supports storage battery 5 The technologies with overcharge and overdischarge protection functions are all prior art. The utility model makes full use of wind energy and light energy, and combines the wind power generator 1 and the solar battery panel 3 to charge the storage battery 5. When there is no wind on a sunny day, the solar battery panel 3 generates electricity, and when there is wind on a sunny day, the solar battery panel 3 and the wind power generator 1 Power generation, wind power generator 1 generates power in rainy days and nights, and the two sets of power generating devices have overcharge and overdischarge protection functions for the battery 5; the utility model is equipped with a switch 6 at the output end of the battery 5, and one end is a DC output, which can provide The DC power supply is used for the DC light bulb 8; the other output terminal of the transfer switch 6 is connected to the inverter 7, and the DC power is converted into AC power through the inverter 7 for the use of the AC light bulb 9.
