Four-layer composite effect dynamic circulation combination firework

Abstract

The invention discloses a combined firework with four-layer compound effect and dynamic cycle, which comprises a first single tube and a second single tube with the same inner diameter and height specifications, and several first single tubes and the same number of second single tubes are arranged at intervals one by one Combined side by side in a row, the adjacent first single cylinder and the second single cylinder are connected by lead wires; the sides of several cylinder rows are arranged in a fan-shaped structure. The fan-shaped structure means that the bottom of each cylinder row is close, and the cylinder row The top is separated, and the rows of cylinders are connected in series according to the order of discharge; the adjustment of the lead wires, the corresponding design of the cylinder body and its combined structure, and the coordination of medicament dosage are combined to realize the whole process of fireworks displaying. During the process, the ever-changing dynamic picture always maintains four levels of effect display, and the boundaries between each level are clear, the combination is harmonious, and the picture has a strong artistic beauty.

Description

technical field [0001] The invention relates to a combined firework. Background technique [0002] According to the definitions of the national standards of the People's Republic of China GB10631-2004 "Safety and Quality of Fireworks and Firecrackers" and GB19593-2004 "Combined Fireworks of Fireworks and Firecrackers" and other normative documents, combined fireworks are fireworks products composed of multiple single tubes.

[0003] However, the display of different effects of the above four levels is only limited to a certain period of time, that is to say, in the whole process of setting off fireworks, only a specific aerial picture is the effect display of the four levels, and the display of the four levels of effects in other periods. There are still three layers in the aerial picture; moreover, in the aerial picture formed by the discharge, the boundaries between the various levels are not clear enough, and the picture is rather messy; making the effect of the aerial picture difficult to meet the requirements
