Combined fireworks capable of being fired and read remotely

Abstract

The invention discloses combined fireworks capable of being fired and read remotely. The combined fireworks are formed by connecting and combining a plurality of mould pressing sleeves and a plurality of control sleeves, sleeve caps (9) are movably connected with the sleeves and the control sleeves, firework gunpowder pieces are arranged in the sleeves, and each control sleeve comprises a remote controller, a receiver (18) and a code reader (19), wherein the receiver (18) and the code reader (19) are arranged on the control sleeve. Metal heating wires (12) are arranged in the sleeves, the sleeves and the sleeve caps (9) are provided with air inlet holes (11) and air outlet holes (10), one ends of the air inlet holes and the air outlet holes are communicated with inner cavities of the sleeves, and the other ends of the air inlet holes are communicated with the other ends of the adjacent air outlet holes. Ball plugs (29) capable of closing and opening the air inlet holes under the air pressure are arranged in the air inlet holes, threading holes (27) communicated with the control sleeves are arranged in the lower ends of the sleeves, and firing lines (20) are arranged in the threading holes. The combined fireworks can be remotely fired and can be tracked and recorded, so that lost fireworks can be found and prevented from being illegally used, considerable economic benefits can be generated for the firework industry, and higher social benefits are brought.

Description

technical field [0001] The present invention relates to fireworks, in particular to combined firework which is ignited and read by remote control. Background technique [0002] As we all know, traditional fireworks are assembled from paper bobbins connected in series by multiple lead wires. It generally has to go through processes such as tube making, mud bottom pressing, insertion, nitrate and bright beads, sealing, assembly and packaging. Various, low production efficiency, high production cost, low standardization or standardization of products, poor working environment, high labor intensity, not conducive to mechanized production line operations, etc., and consume a lot of paper and soil, resulting in the loss of ecological resources waste, but also pollute the environment and destroy ecology. In response to these problems, some people use waste materials to make integral fireworks tubes by molding, and set lead slots connected to the nitrate powder at the bottom of the...

Problems solved by technology

Although the firework of this structure does not need a paper tube or a mud bottom, it can save paper and soil, does not cause environmental pollution, and the firework tube can be reused, but it still has the following problems in use: one is for different specifications. Fireworks need to prepare different molds to suppress different fireworks. The mold structure is also more complicated, the cost of the mold is high, and the presses need to be many. Otherwise, the molds must be replaced frequently to reduce production efficiency; If it is damaged, it will cause the whole fireworks tube to be scrapped, which will increase the cost, and it is not very convenient to recycle, collect and store. It is also more troublesome to string the lead wires. The quality of fireworks products; and as some people use nitrates to carry out illegal activities in the production and use of fireworks, fireworks display does not have the function of identity tracking, so it will leave potential safety hazards, and even criminals.
