Anti-scratch self-cleaning type solar street lamp

Abstract

The invention relates to an anti-scratch self-cleaning type solar street lamp. The anti-scratch self-cleaning type solar street lamp comprises a solar street lamp body which is mounted on a street lamp pole through a fixing seat, wherein a brush is arranged above a solar cell panel of the solar street lamp body and is mounted on a sliding mechanism; an TIO film is plated on a sunshine incidence surface of the solar cell panel; the brush is provided with returning assisting iron block; the brush is connected to a water collecting barrel through a pulling rope, and a fixed pulley is arranged between the brush and the water collecting barrel. The anti-scratch self-cleaning type solar street lamp further comprises an overturning mechanism for overturning the water collecting barrel after the water collecting barrel falls down in certain distance. According to the anti-scratch self-cleaning type solar street lamp, the brush is mounted on the upper surface of the solar cell panel, and the returning assisting iron block and the water collecting barrel are arranged; the brush is pulled through the gravity of the water collecting barrel which is full of rainwater, thus other power is saved,and moreover, water in the water collecting barrel can be poured onto the solar cell panel to wash the solar cell panel, and as a result, the power-free automatic washing of the solar street lamp isachieved.

Description

technical field [0001] The invention relates to a solar street lamp, which belongs to the technical field of lighting appliances. Background technique [0002] In the existing street lighting system, halogen lamps with high energy consumption are usually used, and AC power (220V) is used for direct power supply, which consumes a large amount of electric energy. Therefore, the existing street lighting system can no longer meet the needs of social development. LED has many advantages such as high luminous efficiency, long service life, low energy consumption and convenient installation, and it is more and more used in street lamps. However, during the use of street lamps, dust is attached to the lampshade outside the lampshade. After a long time of use, there is more dust on the surface, resulting in dim light and poor light transmittance. Therefore, in order to solve the problem of dust attached to the lampshade, CN205716994U provides A solar self-cleaning street lamp, compr...

AI Technical Summary

Problems solved by technology

This patent solves the problem of lampshade cleaning, but in fact, after long-term use of solar panels, dust will adhere to the surface, which blocks sunlight and affects the photoelectric conversion efficiency of solar panels

[0003] In order to solve the problem of solar panel cleaning and improve photoelectric conversion efficiency, the existing technology uses batteries to provide power to drive wipers to clean street lamps, but it is based on the light energy conversion rate controller as a trigger switch, and the surface of solar panels is made of monocrystalline silicon. Although polysilicon has high strength, its scratch resistance is still insufficient. The wiper is easy to scratch the surface of the solar panel, and it needs to consume electricity to work

[0004] In addition, some solar street lights in the prior art are equipped with water collecting buckets to collect rainwater, and spray water to the solar panels through pressure valves and nozzles to clean the solar panels, but due to the size limitation of the water collection bucket and the limitation of actual rainfall, it is impossible Realize high-pressure spray washing, which cannot effectively clean the solar panels, and install a water pump to spray water, and the water pump also consumes electricity
