Street lamp achieving rotation through wind energy

Abstract

The invention provides a street lamp achieving rotation through wind energy. The street lamp achieving rotation through wind energy comprises a lamp cap, a lamp pole and a rotating device. The rotating device comprises a wind wheel, a transmission structure and a positioned lampshade. The wind wheel can provide rotation power for the lamp cap under natural wind of certain intensity. The positioned lampshade can limit the position of an internal structure and prevent the internal structure from being exposed to the sun and rain. The transmission structure comprises a crank, a connecting rod, a rocker, a turbine and a worm. The lamp cap is fixed to one end of the rocker so that the lamp cap can swing along with the rocker. A rotary shaft is arranged in the middle of the rocker in the horizontal direction so that the rocker can rotate relative to the positioned lampshade. The other end of the rocker is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the crank. The crank and the turbine are fixed together and rotate around the same axis, and through cooperation of the worm and the turbine, gearing-down can be achieved. The wind wheel is connected with the worm so as to drive the worm to rotate.

Description

technical field [0001] The invention belongs to the field of street lamps, and in particular relates to a wind energy rotating street lamp. Background technique [0002] Existing street lamps are generally fixedly installed on lampposts, which can only illuminate one area. Most street lamps do not work most of the time, so street lamps are generally installed at relatively large intervals in places with few people. Some areas are always dark at night, and it is difficult for travelers to find the road conditions in this part. Contents of the invention [0003] In view of the above-mentioned prior art, the object of the present invention is to propose a wind energy rotating street lamp, which can use wind energy to expand the lighting range at night. [0004] The technical solution of the present invention is achieved in the following way: a wind-powered street lamp includes a lamp holder, a lamp post and a rotating device, the rotating device includes a wind wheel, a tran...
