Abstract

The invention discloses a large outdoor display screen, which belongs to the field of outdoor display screens. The large outdoor display screen comprises a supporting high rod; the upper end of the supporting high rod is connected with a display screen body; the upper end of the supporting high rod is fixed with a power generation box; a driving box is fixedly connected onto the power generation box; and a driving shaft is in rotating connection onto the driving box. Wind can be used to blow a driving fan, the driving fan drives a half-tooth gear through the driving shaft, a rack rod thus moves vertically, a pushing rod fixedly connected onto the lower end of the rack rod pushes the short end of a lever through a connection rod, the long end of the lever is thus pushed to pull a pulling rod to move upwardly, under effects of the lever, the upward moving displacement of the pulling rod is larger than the downward displacement of the pushing rod, the pulling rod can effectively pull a hydraulic push disc to move upwardly, the hydraulic push disc pushes and squeezes hydraulic water, a hydraulic generator is thus driven to generate power, remote cable connection is not needed, and thepower supply is convenient.

Description

technical field [0001] The invention relates to the field of outdoor display screens, more specifically, to a large outdoor display screen. Background technique [0002] With the development of the economy, people's living standards are improving, and display technology has also been greatly improved. Displays are widely used in daily life, especially for some large squares or intersections. Most of the current outdoor display screens are powered by electricity, but for some relatively distant highway intersections, the cables are long and the power supply is troublesome. Contents of the invention [0003] In order to solve the above problems, the present invention adopts the following technical solutions. [0004] A large outdoor display screen, comprising a support pole, the upper end of the support pole is connected with a display screen body, the upper end of the support pole is fixed with a power generation box, the power generation box is fixedly connected with a dr...
