Display shell effect piece capable of displaying air subtitle patterns

Abstract

The invention discloses a display shell effect piece capable of displaying air subtitle patterns. The display shell effect piece comprises quadrangular fire-proof cloth, wherein two corners of the upper edge of the fire-proof cloth are connected with central vertical lines of two parachutes respectively; four corners of the fire-proof cloth are provided with heavy blocks; and one or two surfaces of the fire-proof cloth are provided with subtitle pattern fireworks assembled by using firework powder strips. After a lead of each subtitle pattern firework is ignited, the parachutes are opened in the air, the fire-proof cloth hung below the parachutes is unfolded under the actions of the heavy blocks at the four corners and the parachutes, the subtitle pattern firework which is distributed on the fire-proof cloth is displayed in the air, complex patterns or Chinese character subtitles can be accurately and completely displayed in the formed air subtitle pattern firework for a long time in a way of being optionally adjustable between 6 and 60 seconds, the process equipment is simpler, and the set-off cost is low.

Description

technical field [0001] The invention relates to a display shell effect piece. Especially the effect piece showing the over-the-air subtitle pattern. Background technique [0002] It has always been the dream of people in the fireworks industry to use fireworks to display the designed subtitle pattern effect in the sky. The usual research direction is to use multiple fireworks shells to detonate at fixed points in the air at fixed times, and the combination of multiple explosive point effects forms preset subtitles or patterns. The projectiles are launched into the air on the same plane and explode at the same time, creating a "big footprint" pattern. Not only does it have high requirements for launch equipment, venues, materials, etc., but it also costs a lot, and it is difficult to form complex patterns or Chinese subtitles. [0003] In the prior art, fireworks with subtitle patterns belong to shelf fireworks, that is, a high platform is set up on the ground to hang and ...

AI Technical Summary

Problems solved by technology

Not only does it have high requirements for launch equipment, venues, materials, etc., but it also costs a lot, and it is difficult to form complex patterns or Chinese subtitles, etc.

[0003] In the prior art, fireworks with subtitle patterns belong to shelf fireworks, that is, a high platform is set up on the ground to hang and set off, as disclosed in patents such as the "firework effect tube with sideways fire spraying" disclosed in CN2718504 and the "combined structure of fireworks with subtitle patterns" disclosed in CN2903902. Although it can accurately and completely reflect complex patterns or Chinese subtitles, it cannot achieve air discharge
