Solar street lamp with protection function for urban road illumination

Abstract

The invention relates to a solar street lamp with a protection function for urban road illumination. The solar street lamp comprises a base, a lamp pole, a top plate, an illumination mechanism and a power generation device; the power generation device comprises an adjusting mechanism, a supporting plate, a first photovoltaic panel and two protection mechanisms, the adjusting mechanism comprises atelescopic assembly, a supporting rod, a sliding ring, a sliding rail and two supporting assemblies, and each of the protection mechanisms comprises a rotating chamber, a rotating assembly, a rotatingshaft, a protection plate, a second photovoltaic panel and two connecting rods. According to the solar street lamp with the protection function for urban road illumination, the supporting plate is conveniently driven to rotate through the adjusting mechanism, and the angle of the first photovoltaic panel and the angle of the second photovoltaic panel are adjusted, so that the first photovoltaic panel and the second photovoltaic panel are enabled to be aligned to sunlight, and the power generation efficiency is improved; moreover, after rainfall or snowfall occurs, the first photovoltaic panelcan be shielded by using the protection mechanisms; after the rain and snow stop, the protection plates return to the original position, so that the equipment can normally carry out photovoltaic power generation, the accumulated snow on the first photovoltaic panel is prevented from affecting the photovoltaic power generation, and the practicability of the solar street lamp is improved.

Description

technical field [0001] The invention relates to the field of lighting equipment, in particular to a solar street lamp with protection function for urban road lighting. Background technique [0002] As a kind of traffic lighting facility, solar street light works on a very simple principle. It is a solar panel made of the principle of photovoltaic effect. During the day, the solar panel receives solar radiation and converts it into electrical energy, which is stored in In the battery, when the illuminance gradually decreases to the set value at night, the open circuit voltage of the solar panel changes to a certain extent, the charging and discharging controller automatically detects this voltage and then sends out a braking command, and the battery starts to discharge the lamp head. After the battery is discharged for about 8.5 hours, the charging and discharging controller sends out a braking command, and the battery discharge ends. [0003] However, most of the solar ener...

Problems solved by technology

[0003] However, most of the solar energy installed in the existing solar street lamps is fixed installation. After adopting this installation method, in the weather with a large amount of snowfall, the surface of the solar panel is easily covered by snow, which not only cannot convert energy, but also has relatively heavy snow. Sometimes it will damage the solar panel, not only that, because the solar panel is fixedly installed, it cannot flexibly rotate its angle according to the direction of sunlight, resulting in less solar radiation absorbed by the solar panel per unit time, which reduces the power generation efficiency, which in turn leads to Some solar street lights are less practical
