Intelligent street lamp based on solar photovoltaic power generation

Abstract

The invention discloses an intelligent street lamp based on solar photovoltaic power generation, and relates to the technical field of photovoltaic power generation. The solar street lamp comprises alamp post, a pair of solar cell panels and a pair of street lamps, a hemispherical sealed container is fixed on the peripheral side surface of the lamp post and is filled with expansion gas; the hemispherical sealed container is connected with a movable assembly; the movable assembly is matched between the pair of solar cell panels; a sliding block is connected between the pair of solar cell panels; a supporting seat is fixed on the peripheral side surface of the lamp post; a pair of street lamps is fixedly mounted at the bottom of the supporting seat; two pairs of sliding grooves are symmetrically formed in the upper surface of the supporting seat; a movable block with a hole is in sliding fit in the sliding groove; and a bottleneck is arranged at the top of the hemispherical sealed container. Through the effects of the lamp post, the hemispherical sealed container, the movable assembly and the solar cell panel, the problems that the angle of the solar cell panel of an existing solarstreet lamp is fixed, and the power generation efficiency is low are solved.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, in particular to a smart street lamp based on solar photovoltaic power generation. Background technique [0002] As a kind of traffic lighting facility, solar street lamps work on the principle of using solar panels made of the principle of volt effect. During the day, the panels receive solar radiation and convert it into electrical energy, which is stored in the battery through the charge and discharge controller. At night, when the illuminance gradually decreases to the set value, the open-circuit voltage of the solar panel changes to a certain extent. The charge-discharge controller automatically detects this voltage and sends out a braking command, and the battery starts to discharge the lamp head to provide lighting. [0003] In the existing solar street lights, the solar panels are usually fixedly installed directly on the top of the light pole. When this installation...

Problems solved by technology

[0004] The purpose of the present invention is to provide a smart street lamp based on solar photovoltaic power generation. Through the functions of lamp poles, hemispherical sealed containers, movable components and solar panels, it solves the problem that the angle of the solar panel of the existing solar street lamp is fixed, which is difficult to adjust. It is adjusted so that the power generation efficiency is low, and the problem of using the driving device to adjust the angle of the solar panel will waste part of the electric energy
