Description

Wind-solar hybrid street light

technical field

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

Background technique

Nowadays, with the continuous and rapid development of social economy, energy contradictions are inevitably faced by people, especially in areas far away from the power grid, independent power supply systems have become the most needed power supply, low-cost, high-reliability independent power supply system Which of the independent power sources is the most reasonable is a question that people have been studying and discussing. With the aggravation of the global conventional energy shortage, the utilization of clean and renewable energy such as wind energy and solar energy has become a research topic all over the world. Wind energy as a Energy that is more conducive to development and utilization has great complementarity with solar energy. Combining solar energy and wind energy can make up for the shortcomings of solar energy and wind energy.

Contents of the invention

In order to solve the above problems, the purpose of this utility model is to provide a wind-solar hybrid street lamp with simple structure, novel concept, high conversion efficiency, energy saving and environmental protection, safety and reliability.

In order to achieve the above-mentioned purpose, the technical scheme adopted by the utility model is: a wind-solar complementary street lamp, comprising a solar cell assembly, a light pole, a lamp (light source), a storage battery, an inverter and a wind-driven generator, and is characterized in that the lamp installation On the light arm of the light pole, the solar cell assembly is fixed on the upper part of the light pole, the wind generator is installed on the top of the light pole, and the bottom of the light pole is equipped with an inverter and a storage battery.

The storage battery is a lead-acid storage battery, the solar cell assembly is made of high-conversion-rate monocrystalline silicon or polycrystalline silicon, and the light source can be a low-pressure sodium lamp, an LED lamp or an energy-saving lamp.

The wind turbine adopts a three-blade wind wheel to start at low wind speed, and the dynamic unbalance offsets each other, making the operation more stable and reliable, which effectively solves the safety hazards caused by the windy car and unstable wind speed and direction. Ensure the smooth operation of fan blades, reduce vibration and noise. When the wind speed is lower than the starting wind speed, the fan cannot rotate. After the wind speed reaches the starting wind speed, the fan starts to rotate and drives the generator to generate electricity. The output power is supplied to the load and charged to the battery. When the terminal voltage of the storage battery pack reaches the set maximum value, the signal voltage is obtained by the voltage detection, and the inverter is switched to make the system enter the voltage stabilization control.

Due to the strong complementarity between solar energy and wind energy, the wind and solar hybrid power generation system makes up for the resource defects of wind power and photovoltaic independent systems. reliability, and can reduce the cost of the power generation system.

The beneficial effects of the utility model are: simple structure, novel conception, energy saving and environmental protection, and good economic benefits. Since street lamps must be powered by buried cables, the construction cost of power supply lines for street lamps is very high on roads that are more than three kilometers away from the power point. Especially on the roads in the outer suburbs, the cost of the power supply line of the street lamp is high, and the electric energy consumed on the line is large, but the utility model does not need a power transmission line, does not consume electric energy, and has strong practicability and popularization.
