Anti-freezing solar street lamp

Abstract

The invention relates to an anti-freezing solar street lamp. The lamp comprises a supporting column, a supporting plate, a protective shell, a solar panel, a lamp tube and a fixing rod, and further includes a heat dissipation mechanism and an anti-freezing mechanism. The heat dissipation mechanism comprises an air exhaust assembly and two filter screens; the air exhaust assembly comprises an air extracting pump, an air inlet pipe and an air outlet pipe; the anti-freezing mechanism comprises a connecting box, a detection assembly, two control assemblies, two supporting rods, two connecting pipes and a plurality of nozzles; the detection assembly comprises a fixed box, two branch pipes and two pistons; and the control assembly comprises a connecting rod, a sealing ring, a moving rod, a fixing ring, a sealing plate, a support and a spring. According to the anti-freezing solar street lamp, the function of cooling and radiating the interior of the protective shell is achieved through the heat dissipation mechanism, the situation that normal work of the lamp tube is affected due to the fact that the temperature in the protective shell is too high is avoided, the function of heating the solar panel is achieved through the anti-freezing mechanism, and the freezing phenomenon caused by the too low temperature of the solar panel is avoided.

Description

technical field [0001] The invention relates to the field of street lamps, in particular to an anti-freezing solar street lamp. Background technique [0002] Solar street lights are powered by crystalline silicon solar cells, maintenance-free valve-regulated sealed batteries (colloidal batteries) store electric energy, super bright lamps are used as light sources, and are controlled by intelligent charge and discharge controllers, and are used to replace traditional public electric lighting. . [0003] After the existing solar street lamps are illuminated for a long time, the lamp tubes tend to generate more heat, which easily leads to damage to the lamp tubes due to overheating, thereby affecting the normal lighting work of the lamp tubes. Not only that, the existing solar street lamps usually Relying on solar panels for solar power generation, if the temperature of the solar panels is low, the surface is prone to icing, which affects the efficiency of absorbing sunlight, ...

[0003] After the existing solar street lamps are illuminated for a long time, the lamp tubes tend to generate more heat, which is easy to cause damage to the lamp tubes due to overheating, thereby affecting the normal lighting work of the lamp tubes. Not only that, the existing solar street lamps usually Relying on solar panels for solar power generation, if the temperature of solar panels is low, the surface is prone to icing, which affects the efficiency of absorbing sunlight, thereby affecting the power generation effect and reducing the reliability of existing solar street lights
