Detailed ways

The utility model is described with reference to accompanying drawing now.

The wind-solar hybrid street lamp provided by the utility model includes a wind-driven generator 10, a solar plate 20, a charge-discharge controller 30 electrically connected to the wind-driven generator 10 and the solar plate 20 through wires (not labeled), and a charge-discharge controller 30 electrically connected accumulator 40 and the high-power LED50 street lamp electrically connected with accumulator 40. In addition, the components such as the wind generator 10, the solar panel 20, and the high-power LED 50 can be installed on the street light pole 70, and the street light pole 70 is supported on the base 60 fixed to the ground.

The wind-solar hybrid street lamp utilizes the wind generator 10 and the solar plate 20 to convert wind energy and solar energy into electric energy for road lighting. The two power generation systems complement each other, providing higher reliability for road lighting, green and environmentally friendly lighting, and have extensive promotion and utilization value.

The utility model provides a wind-solar complementary street lamp, the invention point of which is to use a wind generator and a solar plate to realize joint power generation (complementing each other), thereby providing sufficient power for the street lamp. It works as follows.

Wind energy is converted into alternating current through wind generators, and then the generated alternating current is input to the controller; in addition, in the case of sunlight, solar energy is converted into direct current through solar panels (which can be solar panels) and input to the above-mentioned controller . The controller converts the above two kinds of electric energy into 12V DC and stores them in the storage battery such as the battery, and then releases the DC when needed (such as when it is dark at night), so as to supply power for LED street lights (such as high-power LED street lights).

The wind power generator 10 has the following advantages:

(1) The starting wind speed is low, the system utilization efficiency is high; the operation vibration is low, the noise is low; the volume is small and exquisite.

(2) The new power output device overcomes the annoyance of cable winding when the traditional small wind turbine is facing the wind.

(3) Humanized wiring device is adopted to facilitate electrical installation, maintenance and inspection.

(4) The blades of the wind rotor are precision injection molded with new materials and new technology, coupled with optimized aerodynamic shape design and structural design, so that the wind rotor has a high wind energy utilization coefficient and a power generation per 100 watts under the same sweeping area. The material consumption is low.

(5) The alternator adopts the patented permanent magnet rotor magnetic circuit structure, coupled with a special stator design, which effectively reduces the resistance torque of the generator, and at the same time makes the wind wheel and generator have better matching characteristics, expanding the The effective wind speed range is increased, and the power generation capacity is increased.

(6) A novel electromagnetic brake auxiliary device is designed by using the characteristics of the generator itself, which simplifies the structure of the unit and improves the reliability of the unit operation.

(7) The damping device is used for the wind, which not only ensures the sensitivity and stability of the wind turbine steering, but also avoids the unit vibration and power generation capacity reduction caused by the frequent wind of the wind turbine generator.

The solar plate 20 can be a monocrystalline silicon solar plate with a conversion efficiency as high as 16%. Its service life is as long as 20 years.

The charging and discharging controller 30 has the following characteristics:

Short-circuit protection: When the external circuit is abnormal or short-circuited, the machine will automatically turn off the output.

Under-voltage protection: When the battery voltage is lower than 85% of the rated value, the output circuit will be automatically closed to prevent the battery from over-discharging.

Overvoltage protection: When the voltage exceeds +17% of the rated value, the machine will automatically open the discharge bypass.

Anti-reverse connection protection: When the wire is connected in reverse, reverse connection protection.
