An environmentally friendly and pollution-free photovoltaic solar street light

Abstract

The invention relates to a solar street lamp, in particular to an environment-friendly and non-polluting photovoltaic solar street lamp, including a lamp pole, a lampshade, a solar battery panel, a rotating water supply device, a water storage tank, a heat dissipation pipe, a dust cover, a heat dissipation rope and a flywheel . There are several heat-dissipating pipes. The heat-dissipating pipes include a heat-absorbing section and a heat-radiating section, and the heat-absorbing section and the heat-radiating section are connected end to end to form a closed loop. The bottom end is a U-shaped tube, and the left side of the U-shaped tube is located outside the lampshade and communicates with the through hole at the lower right part of the water storage tank. The rotating water supply device is located above the light pole and includes a support rod, a rotating shaft, a water storage plate and a water supply plate. The invention utilizes the gravity of rainwater to drive the rotating device and uses the rainwater as a heat dissipation medium to complete the automatic heat dissipation of circuit elements and storage batteries, saving energy resources and requiring no manpower control.

Description

Technical field[0001]The invention relates to a solar street lamp, in particular to an environmentally friendly pollution-free photovoltaic solar street lamp.Background technique[0002]Street lights are the most common equipment for urban road lighting, and with the advancement of technology, solar energy is used more and more for circuit lights. For the protection of circuit components and batteries, in order to prevent dust and water from causing damage, circuit components and batteries are often placed inside the lampshade, which results in circuit components and batteries in a relatively closed cavity. Problems such as heat generation and difficulty in heat dissipation, which seriously affect the normal operation of circuit components and shorten the service life of lamps and batteries.Summary of the invention[0003]Aiming at the problems in the prior art, the present invention provides an environmentally friendly pollution-free photovoltaic solar street light, which uses air and ...

AI Technical Summary

Problems solved by technology

For the protection of circuit components and batteries, in order to prevent them from being damaged by dust and water, the circuit components and batteries are often placed inside the lampshade, which leads to the circuit components and batteries being in a relatively closed cavity. It works hot and has problems such as difficulty in heat dissipation, which seriously affects the normal operation of circuit components and shortens the service life of lamps and batteries
