Abstract

The invention discloses a sunlight tracking device for a street lamp, which comprises a main shaft mounted on a telegraph pole and capable of rotating around the central shaft of the telegraph pole at 180 degrees, a solar PV plate, a driving mechanism for driving the main shaft, and a controller capable of correspondingly controlling the driving mechanism according to the calculated sun elevation angle data in advance at each period so as to control the main shaft to rotate intermittently; the driving mechanism comprises an impulse generator, an electromagnetic valve driven by the impulse generated by the impulse generator, a gear rack capable of reciprocating up and down while driving the main shaft to synchronously rotate, and a disk capable of rotating at 360 degrees under the control of the electromagnetic valve while driving the gear rack to reciprocate up and down. The sunlight tracking device has the advantages of simple structure, reasonable design, simplicity and convenience in operation, low work cost, reliable performance and high operation precision, can effectively solve the defect that the conventional solar power generation device for the street lamp is low in solar energy utilization efficiency and has smaller generated electrical energy.

Description

technical field [0001] The invention belongs to the technical field of automatic sunlight tracking, and in particular relates to a sunlight tracking device for street lamps. Background technique [0002] Most of the solar photovoltaic panels installed on the existing solar street lamps are fixedly installed on utility poles. Therefore, in the actual use process, the solar photovoltaic panels cannot always face the sun, and their power generation efficiency has not been fully and effectively utilized. If the light-receiving area of ​​the solar photovoltaic panel can move with the movement of the sun, the power generation of the same solar photovoltaic panel will be greatly improved. According to relevant data, its power generation efficiency can be increased by 20% to 30%. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a solar tracking device for street lamps, which has a simple structure, reasonable design, easy...
