AI Technical Summary

Technical Problem

The existing lifting mechanism of the light pole is prone to rapid descent under malfunction or external impact, causing the cylinder to fall, and traditional safety protection measures cannot effectively prevent structural damage.

Method used

Multiple safety protection measures are adopted, including the coordinated operation of the swing arm assembly, push rod fixing assembly and buffer assembly. Rapid descent is detected by the center of gravity shift, instantaneous locking and friction energy dissipation are achieved, and the connection method is changed to a flexible connection to absorb energy.

Benefits of technology

This effectively prevents stress concentration in street light poles and photovoltaic panel poles caused by rapid movement, reduces the probability of structural breakage or damage, and ensures the safe operation of the equipment in case of emergencies.

Abstract

This invention relates to the field of light pole technology, specifically to an energy-saving light pole with adjustable tilt angle, comprising a light pole, a base installed at the bottom of the light pole, a cylindrical body slidably fitted on the light pole, and street light support poles and photovoltaic panel support poles respectively connected to the outer wall surface of the cylindrical body; a control panel and a lifting assembly are installed inside the control chamber, the traction rope of the lifting assembly extends to the top of the light pole, is guided by a guide box and then fixedly connected to the cylindrical body; a guide groove is provided along the axial direction on the outer wall of the light pole, and multiple contact rods are arranged at intervals along the length direction in the guide groove; the cylindrical body adopts a hollow structure and is equipped with a locking mechanism inside; when the cylindrical body descends normally and slowly, the swing arm assembly contacts the adjacent contact rods in sequence and passes smoothly; when the cylindrical body descends rapidly due to a malfunction, the contact rods mechanically interfere with and lock the locking mechanism; the push rod fixing assembly triggers a multi-point friction clamping mechanism to dissipate energy in the cylindrical body, and the buffer assembly effectively dissipates energy through connection method conversion and elastic energy storage friction energy dissipation, reducing the probability of damage to the falling equipment.
