Advertising board adopting hydrogen balloon

Abstract

The invention discloses an advertising board adopting a hydrogen balloon, which can carry out wind power generation, wherein the generated electricity can maintain the demand of lighting effect on theadvertising board, so that the advertising board can float in the air for a long time, and manual maintenance is not needed. The advertising board comprises a wind generator, the hydrogen balloon, and an advertising board body, wherein the hydrogen balloon is ring-shaped, and the wind generator sleeves the middle of the ring-shaped hydrogen balloon; for blades in the wind generator, a rotation shaft is arranged in coaxial with the hydrogen balloon; a storage battery is arranged at the lower side of the inside of the hydrogen balloon; and the advertising board body is hung below the hydrogen balloon, an LED display screen and an LED control circuit board are arranged on the advertising board body, and the LED control circuit board is connected with the storage battery. The advertising board adopting the hydrogen balloon provided by the invention realizes work high above the ground, can receive the great wind action, and is high in generating efficiency, and thus the advertising board can be conveniently used in cities; and the electricity generated by the wind generator is used for maintaining the electricity used by the LED display screen for a long term, the manual maintenance isneeded, and thus the advertising board is convenient and reliable.

Description

technical field [0001] The invention relates to the field of advertising, in particular to a hydrogen balloon billboard. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×109 MW, of which the usable wind energy is 2×107 MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. Wind has been used by people for a long time, mainly through windmills to pump water, grind flour, etc., but now, people are interested in how to use wind to generate electricity. Wind turbines use wind power to drive the blades to rotate, and then increase the speed of rotation through a speed increaser to drive the generator to generate electricity. Usually, wind turbines are erected on the ground, and the wind force on the ground is often not as strong as that in the sky due to the influ...
