Solar street lamp with cleaning function for brightening engineering

Abstract

The invention relates to a solar street lamp with a cleaning function for brightening engineering. The solar street lamp comprises a base, a lamp post, a top plate, a processor, an illumination mechanism and a photovoltaic mechanism, wherein the illumination mechanism comprises a lampshade, a transverse plate and a sealing assembly. The sealing assembly comprises a sealing plate, a fixing plate, afirst motor, a rotating shaft, a lifting block, a sliding ring and a supporting rod. The photovoltaic mechanism comprises a driving bevel gear, a cleaning plate, a cleaning block, a connecting assembly and two photovoltaic assemblies. When the solar street lamp with the cleaning function for brightening engineering runs, in the daytime, the sealing plate in the illumination mechanism blocks the lampshade to ensure night illumination luminance, a photovoltaic panel in the photovoltaic mechanism performs photovoltaic power generation; at night, the sealing cover rotates downwards, road lightingis facilitated, the cleaning plate drives the cleaning block to move on the surface of the photovoltaic panel for cleaning, the dustproof film is used for covering the surface of the photovoltaic panel for dust prevention, cleanliness of the photovoltaic panel is guaranteed, the photovoltaic power generation efficiency in the daytime is improved, and therefore the practicability of the device isimproved.

Description

technical field [0001] The invention relates to the field of lighting engineering, in particular to a solar street lamp with cleaning function used in lighting engineering. 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, during the use of...

Problems solved by technology

[0003] However, during the use of existing solar street lights, the lamp tube and solar panel are directly exposed to the outside at the same time to avoid easy dust accumulation. After the lamp tube accumulates dust, it will affect the night lighting brightness of the equipment, and after the solar panel accumulates dust, it will affect the solar energy in sunny days. The amount of sunlight absorbed by the panels, resulting in a reduction in power generation, which in turn reduces the practicality of existing solar street lights
