Rain-proof solar street lamp

Abstract

The invention relates to a rain-proof solar street lamp and belongs to the technical field of non-portal illuminating devices or systems thereof. The solar street lamp comprises a base. A storage battery and a controller are arranged in the base. The base is fixedly connected with a support. The support is connected with a lamp pole and a solar cell panel. A lamp is mounted on the lamp pole, and the outside of the lamp is covered with a lampshade. The top end of the support is connected with a supporting seat. The supporting seat is connected with a fixing support. A first through hole is formed in the supporting seat. The lower portion of the supporting seat communicates with a U-shaped tube. The U-shaped tube is connected with a branch tube. The branch tube is connected with an air bag.The air bag is connected to one end of the solar cell panel. A piston is in sliding fit with the interior of the U-shaped tube. The piston, the U-shaped tube, the branch tube and the air bag form a closed cavity. The interior of the closed cavity is filled with carbon dioxide gas, and pressure of the closed cavity and the external atmospheric pressure keep a relative balance. According to the technical scheme, the weight of rainwater in rainy weather is reasonably used to serve as the power source, operation is convenient, the solar cell panel can be protected, the service life of the street lamp is prolonged, and the practicability is high.

Description

technical field [0001] The present invention belongs to the technical field of non-portable lighting devices or systems thereof. Background technique [0002] Solar energy is clean, pollution-free and renewable green energy. Using solar power to generate electricity has advantages that other conventional energy sources do not have, such as cleanliness, safety, relative breadth and sufficiency of energy, long life, and maintenance-free. The solar street lights using solar energy do not need to lay cables, do not need AC power supply, and do not generate electricity bills; use DC power supply and control; have good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, economical and practical Etc. It has been widely used in urban main and secondary arterial roads, residential areas, factories, tourist attractions, parking lots and other places. [0003] However, for some rainy ...
