Overhead street lamp capable of preventing icing

Abstract

The invention discloses an overhead street lamp capable of preventing icing. The overhead street lamp comprises a fixed seat and a lamp holder which are fixedly connected, a lamp body is fixedly installed in the lamp holder in a sleeved mode, a water removal mechanism and a heat removal mechanism are arranged on the lamp holder, and the water removal mechanism comprises a ventilation heat collection plate fixedly arranged in the lamp holder in a sleeved mode. The ventilation heat collection plate connected with the lamp body is arranged, the memory spring capable of providing traction and supporting effects on the lampshade is arranged through the guide rod, the memory spring deforms under the extremely-short temperature condition so that the lampshade can move up and down, and therefore low-temperature liquid and ice and snow on the lampshade can be accelerated to be separated and slide off, and the liquid and the ice and snow are prevented from being condensed on the lampshade; a cold driving wind wheel is arranged through a driving rack and a driven gear which are connected in a meshed mode and a first-stage gear and a second-stage gear so as to provide low-temperature cold air flow. The threaded rod and the ratchet wheel which are in meshed connection and the third-stage gear and the fourth-stage gear are used for driving the thermal driving wind wheel to rotate, so that discharging of high-temperature airflow in the lamp holder and the lampshade is accelerated, and efficient heat dissipation is achieved.

Description

technical field [0001] The invention relates to the technical field of street lamp infrastructure, in particular to an elevated street lamp capable of preventing freezing. Background technique [0002] Due to the development of the times, in order to ensure the smoothness of the road at all times and to improve the safety of road traffic, it is necessary to provide sufficient vision brightness for drivers. Therefore, street lights have become one of the necessary items in infrastructure construction in many places. [0003] At present, the installation of street lamps mostly adopts the method of erecting at high places, and in order to ensure the range and intensity of illumination, no complicated protection measures are taken. In this way, elevated street lamps with simple structures can be used normally in areas with general conditions, while in some Areas with distinct climatic characteristics or extreme weather are prone to various problems. The impact of rain and snow ...
