Description

Wind-solar complementary lighting device

technical field

The utility model relates to a device for supplying and illuminating by using wind energy and solar energy to complement each other, which is mainly used for high-speed monitoring power supply, urban roads, industrial or residential quarters, parks, docks and other public places.

Background technique

Street lamps are necessary lighting equipment in many public places, but few people realize that street lamps are also a large power consumer; and ordinary street lamps not only need to dig trenches and wiring, pay electricity bills, but also the entire area if there is a power outage. Due to the advantages of energy saving, environmental protection and renewable, wind and solar hybrid street lamps have been gradually applied to street lamp facilities, which not only save coal, gas, electricity, etc., but also reduce environmental pollution, and contribute to the country's energy saving and emission reduction. The current wind-solar hybrid street lamp generally includes a light pole, on which a wind generator is installed on the top of the light pole, a solar panel and a lighting fixture are installed on the upper part, a controller is installed inside, and a battery and an inverter are installed on the lower part. The wind generator and solar panel are connected to the controller with wires, the controller is connected to the battery pack, the battery pack is connected to the inverter or DC load, and the inverter is connected to the AC load. Wind power generators convert wind energy into electrical energy or solar energy converts light energy into electrical energy, which is stored in battery packs, and the battery packs directly provide the power required for lighting fixtures.

However, at present, the solar panels in the wind-solar hybrid street lamps are generally installed on one side of the light pole. For example, the Chinese patent ZL200810062840.5 titled "a wind-solar hybrid street lamp" is disclosed in the accompanying drawing 1 of the specification. The solar panel installed on one side of the light pole, but when the sun is rotated or not directly illuminated by the solar panel, the absorption of solar energy by the solar panel is limited, which reduces the energy conversion of solar energy into electrical energy. Most of the current wind-solar complementary lighting devices still have a shortcoming: there is no lightning protection device, even if there is, it only provides a kind of thinking, and it cannot solve practical problems in practice. For example, the Chinese patent ZL200820168336. According to the utility model patent of Complementary Street Lamp, there is a cement tank next to the bottom of the metal light pole, and there is salt water in the cement tank, and the metal wire is led from the metal light pole into the salt water, and the salt water contains a large amount of conductive ions. Neutralize the ions in the lightning current to achieve the effect of lightning protection. The cement tank cannot completely block the rainwater from entering, and the salt water itself is weathered and volatilized, which leads to the failure of the conductive effect of the salt water, and thus loses the lightning protection effect. Another shortcoming of the current wind-solar hybrid lighting device is: since there is no backup battery, most of them can only maintain the lighting time for 5 nights under the condition of no wind and no sunlight.
