Firework bomb structure

Abstract

The invention relates to the field of fireworks, in particular to a firework bomb structure. The structure comprises an elastic outer ring, a weight part is arranged on a ring body of the elastic outer ring, a supporting strip is arranged in the elastic ring body, and a pattern layer used for displaying patterns is installed at the upper portion of the supporting strip.

Description

technical field [0001] The invention relates to the field of fireworks, in particular to a fireworks shell structure. Background technique [0002] According to the current fireworks technology, fireworks and firecrackers are divided into the following five categories according to the structure of fireworks and firecrackers and the form of movement after discharge, including: spraying: products that mainly spray flames and sparks when setting off; rotating category: the main body when setting off Products that rotate by themselves but do not lift into the air; lift-off categories: products whose main body is directed into the air during discharge; rotary lift-off categories: products that rotate and lift into the air by themselves during discharge; spit beads: launch regularly from the same cylinder during discharge Produce products with multiple colored beads, colored flowers, and sounds. [0003] After the fireworks are lifted into the sky, there are only the following me...

Problems solved by technology

In advance, it is necessary to repeatedly launch many launches into the sky for actual experiments, but in the end it is still impossible to control the air distribution status, and there is no good way abroad; fifth, before 2010, foreign countries have used small unmanned aircraft that can use autonomous navigation to organize, Accurate group flight to generate dynamic aerial images is first realized indoors by relying on stereo camera equipment and image processing algorithms, and then equipped with core devices to carry out this kind of aerial group flight outdoors. The high-performance core devices carried have not yet been Localization, its algorithm is also very good; sixth, use a small or large projector to project onto the outer wall or screen, the screen can be a water waterfall curtain wall, or a smoke wall; seventh, burst out a piece or a volume of traditional The paper banners are printed with subtitles, which are reliable, safe and stable, but the effect in the air is relatively poor, and the observation effect varies greatly from different angles; eighth, the scattered gunpowder powder is scattered into pattern images, which are usually drawn by computers The ideal effect picture cannot be realized accurately in fact. It is difficult to solve the real problem of creating a continuous and stable spatial distribution of shapes and subtitles, and continuous luminescence.
