Solar street lamp apparatus having solar cell panel capable of self-cleaning and easily-adjustable inclination angles

Abstract

The invention discloses a solar street lamp apparatus having a solar cell panel capable of self-cleaning and easily-adjustable inclination angles. The apparatus includes an electric pole which is arranged in a vertical direction. The left side of a top part of the electric pole is provided with a box body through a rotary hinging structure and an automatic telescopic adjusting mechanism. The rotary structure is arranged above the automatic telescopic adjusting mechanism. The top part of the box body is provided with a thermal insulation board which is provided with a solar cell panel thereon. The box body is provided with a storage battery pack, a LED lamp module, a voltage-stablizer, a remote signal receiver and an intelligent controller having the timing keeping and time setting functions therein. The side part of the box body is provided with a radiating hole. The radiating hole is provided with a water-resisting and ventilated membrane therein. The box body is provided with an automatic reciprocating wiping apparatus which is intended for wiping the upper surface of the solar cell panel. According to the invention, the apparatus can automatically adjust the inclination angles of the solar cell panel based on the radiation angles of the sun, fully increases photovoltaic conversion rate, can automatically clean the solar cell panel, and since the solar cell pane and the storage battery are integratedly mounted, the apparatus has strong reliability, has time keeping and time setting functions, and avoids waste of electricity.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to a solar street light device with automatic cleaning of solar panels and easy adjustment of inclination angle. Background technique [0002] my country is very rich in solar energy resources, with a theoretical reserve of 1.7 trillion tons of standard coal per year. The potential for the development and utilization of solar energy resources is very broad. In China's vast land, there are abundant solar energy resources. The annual average daily radiation in most areas is more than 4 kWh per square meter, and the daily radiation in Tibet is as high as 7 kWh per square meter. In recent years, my country's solar photovoltaic industry has developed rapidly, and my country has developed into an important producer of solar cells. The assembly of solar panels is convenient, and the size, power, and appearance can be adjusted arbitrarily according to needs, u...

Problems solved by technology

[0004] The solar panels of most solar street lights are separated from the battery, which is not easy to install, and the exposed lines are easy to age

Regardless of the time period, whether it needs to be connected or not, the solar street light is always on all night, which accelerates the aging of components and shortens the service life

In addition, because the angle of the sun directly hitting the earth is different throughout the year, the angle of the solar panel of the existing solar street light is relatively fixed and cannot be adjusted according to the angle of sunlight, which also affects the photoelectric conversion rate.

[0005] In addition, solar panels generally use monocrystalline silicon, polycrystalline silicon or amorphous silicon cells as components. Dust, bird droppings and other stains on the surface of solar panels will affect the photoelectric conversion rate. At present, there is no research on the surface of solar panels. clean device
