Description

Technical Field

[0001] This invention relates to a combination of decorative fireworks. Background Technology

[0002] A combination of fireworks consists of several launch tubes arranged side by side. Each launch tube contains propellant, effect components, and a fuse. After the fuse is lit, the effect tube is launched into the air, producing the corresponding display effect. The light and color effects can be divided into two categories: one is the effect produced when the effect component is launched to the top and ignites (burns and / or explodes), called the combustion and explosion light and color effect, such as dahlias, waves, coconuts, brocade crowns, flower crowns, handrails, willows, waterfalls, falling leaves, wandering stars, silver fish, chrysanthemums, etc.; the other category is the effect produced when the effect component burns during its ascent, called the trail light and color effect, such as flashes, candlelight, rain, brocade tails, bouquets, etc.

[0003] In existing technologies, although the effects of combustion and explosion light color and the effect of trail light color are often combined, the rising trail light color effect and the falling combustion and explosion light color effect cannot be connected by the light color effect of bending shape, which limits the expressiveness of fireworks display. Summary of the Invention

[0004] To address the aforementioned drawbacks, the technical problem this invention aims to solve is to provide a combination firework that achieves a seamless connection between the rising trail light and color effect and the descending explosive light and color effect through a bent shape, effectively enhancing the expressiveness of the fireworks display. To solve this technical problem, the present invention employs a combination firework that utilizes a bent shape to connect the trail and explosive light and color effects. This firework is composed of several launch tubes arranged side-by-side. Each launch tube contains propellant, an effect tube, and a fuse. The key feature is that each launch tube is tilted to the same side. The lower end of each effect tube has a sealing layer, outside which trail pyrotechnic powder is placed. An effect powder column is placed inside the effect tube, coated with a varnish outer layer. An outer layer of pyrotechnic powder adheres to the varnish outer layer. The upper end of the powder column is capped with cardboard, and the upper end of the effect tube is sealed with tin foil. The trail pyrotechnic powder and the outer layer of pyrotechnic powder are connected by a timed fuse.

[0005] The trail pyrotechnic powder is composed of the following components in the following weight ratios: 56-58 parts barium nitrate, 19-21 parts magnesium-aluminum alloy, 14-16 parts potassium perchlorate, 5-7 parts high-chlorinated polyvinyl chloride resin, 5-7 parts colorant, and 5-7 parts phenolic resin.

[0010] Preferably, the trail pyrotechnic powder is composed of the following components in the following weight ratios: 58 parts barium nitrate, 20 parts magnesium-aluminum alloy, 15 parts potassium perchlorate, 6 parts chloride ion resin, and 6 parts phenolic resin.

[0011] The outer pyrotechnic powder is composed of the following components in the indicated weight ratios: 60 parts black powder, 15 parts magnesium-aluminum alloy, 5 parts sulfur, 35 parts potassium perchlorate, and 7 parts phenolic resin.

[0012] The effective explosive column is composed of the following components in the indicated weight ratios: 60 parts black powder, 15 parts magnesium-aluminum alloy, 15 parts sulfur, 15 parts sodium oxalate, 5 parts starch, and 10 parts potassium perchlorate.

[0013] Preferably, the burning rate of the timing lead is 80 seconds / meter, and its length is 5 to 5.5 centimeters. This provides a suitable ignition connection.

[0014] The preparation method for the effect powder column of a combined firework that utilizes a bent shape to connect the trail and the light and color effect of combustion consists of the following steps:

[0015] S1: Weigh each component according to the formula of the effective gunpowder column, mix them evenly according to the general method, moisten with solvent, put them into a mold and press them into gunpowder columns with a hydraulic press, and dry them; the effective gunpowder column is composed of the following components in the following weight ratio: 59-61 parts of black powder, 14-16 parts of magnesium-aluminum alloy, 14-16 parts of sulfur, 14-16 parts of sodium oxalate, 4-6 parts of starch, and 9-11 parts of potassium perchlorate.

[0020] Figure 1 This is a schematic diagram of the overall structure of the combined fireworks in Example 1;

[0021] Figure 2 This is a schematic diagram of the internal structure of the effect cylinder in Example 1;

[0022] Figure 3 This is a schematic diagram of the combined fireworks display effect in Example 1. Detailed Implementation

[0023] See appendix Figure 1-3 This illustrates a specific structure of the present invention. The combined fireworks, utilizing a bent shape to connect the trail and the explosive light effect, consist of 168 launch tubes 1 arranged in 14 x 12 rows side-by-side. Each launch tube 1 is filled with propellant (not shown in the figure) in a conventional manner, contains an effect tube 5, and is equipped with an ignition fuse 2, a spare ignition fuse 3, and a ignition transfer fuse 4. All launch tubes 1 are tilted to the same side; in this example, the tilt angle H of the launch tubes 1 is 65 degrees. In other embodiments, this tilt angle H can be set between 60 and 70 degrees, such as 61, 62, 63, 64, 66, 67, 68, 69, etc., all of which can achieve the purpose of the invention.

[0024] The lower end of the effect tube 5 is provided with a mud-head sealing layer 8, and a trailing pyrotechnic powder 7 is installed outside the sealing layer 7. An effect powder column 11 is installed inside the cavity of the effect tube 5. The effect powder column 11 is coated with a varnish outer layer 13, and an outer layer of pyrotechnic powder 9 is adhered and wrapped outside the varnish outer layer 13. The upper end of the effect powder column 11 is covered with a circular cardboard 12 (paper bag). The upper end of the effect tube 5 is sealed with tin foil 10. The trailing pyrotechnic powder 7 and the outer layer of pyrotechnic powder 9 are connected by a timing fuse 6. In this example, the burning rate of the timing fuse is 80 seconds / meter, and its length is 5 centimeters. Its length and burning rate can provide a proper ignition connection for the conversion between the trailing light and color effect 100 and the explosive light and color effect 300.

[0025] The trail smoke powder 7 is composed of the following components in the following weight ratios: 58 parts barium nitrate, 20 parts magnesium-aluminum alloy, 15 parts potassium perchlorate, 6 parts high-chlorinated polyvinyl chloride resin, 6 parts chloride ion resin, and 6 parts phenolic resin. They are mixed evenly, moistened, adhered, and solidified into the mud head sealing layer 8 by general methods.

[0026] The outer layer of pyrotechnic powder 9 is composed of the following components in the following weight ratios: 60 parts black powder, 15 parts magnesium-aluminum alloy, 5 parts sulfur, 35 parts potassium perchlorate, and 7 parts phenolic resin.

[0027] The effective explosive column 11 is composed of the following components in the indicated weight ratios: 60 parts black powder, 15 parts magnesium-aluminum alloy, 15 parts sulfur, 15 parts sodium oxalate, 5 parts starch, and 10 parts potassium perchlorate.

[0028] The preparation method of the effective drug column consists of the following steps:

[0029] S1: Weigh each component according to the formula of the drug column, mix them evenly according to the general method, moisten with a solvent (such as water or alcohol), put them into a mold and press them into drug columns with a hydraulic press, and dry them;

[0030] S2: Dilute the varnish with a thinner (such as banana oil), then coat the outer surface of the effect drug column prepared in S1 with a layer of varnish for later use;

[0031] S3: Weigh each component according to the outer layer pyrotechnic formula, mix them evenly according to the general method, coat the outer surface of the varnish outer layer with a layer of powdered outer pyrotechnic, and obtain the product after the varnish dries.

[0032] Using the above technical solution, the effect tube inside the launch tube is launched obliquely into the air. The contrail pyrotechnics outside the effect tube are ignited by the propellant. The contrail pyrotechnics burn during the ascent of the effect tube, forming an obliquely rising contrail light and color effect 100. After the effect tube reaches the top of the launch stroke, the outer layer of pyrotechnics, ignited by the timed fuse, burns and breaks through the cardboard and tin foil to spray fireworks, forming the first light and color effect. Moreover, it drives the effect column out of the effect tube and falls due to its own weight. The effect column ignited by the outer pyrotechnics burns and sprays fireworks (without exploding) during the initial stage of its fall, forming the second light and color effect. The effect column burns and sprays fireworks during the rest of its fall, forming a descending combustion and explosion light and color effect 300 (without exploding). The double-layered structure of the outer coating layer, which adheres to and wraps the outer layer of pyrotechnic powder, and the formulation of each pyrotechnic powder ensure that the ignition timing of the effect charge matches its trajectory. This allows the first and second light color effects to be reliably combined to form a bent light color effect 200, and ensures that the bent light color effect 200 effectively connects the tail light color effect 100 and the combustion light color effect 300, forming a smooth transition between the inclined rising light color and the falling light color.

[0033] In summary, this invention, through the synergy of the launching device, the structure of the effect tube and its propellant, the relevant pyrotechnic formula, and the ignition mechanism, can achieve a seamless transition between the rising trail light and color effect and the descending explosion light and color effect via a bending shape, effectively enhancing the expressiveness of fireworks displays. A typical application is to create an aerial image resembling rice ears, with the trail light and color effect 100 resembling a rice stalk, the explosion light and color effect 300 resembling a drooping rice ear, and the bending shape light and color effect 200 resembling the connection between the rice stalk and the drooping rice ear.
