Embodiment 1

[0027] Embodiment 1 uses the safety self-destruction device of fireworks and firecrackers as an example for fireworks shells, figure 2 As mentioned above, the fireworks bomb is placed on the base 17 in the paper tube shell, and is snapped into the inner tube support wall 16. The fireworks bomb is provided with a pre-set aqueduct 15, and the rubber plug on the aqueduct is convenient for the aqueduct hose 13, 14. Insert, the safety self-destruction device is pressed into the upper end of the paper tube shell, the safety self-destruction device is a closed structure, made of plastic injection molding, the top cover 2 is equipped with a one-way water injection pressurization valve 1, and the upper end of the pressurization valve can be covered The rubber cover is sealed and poured to prevent damage after collision; the inner tube 4 of the lead wire is placed on the inner wall of the high-pressure water chamber 5, and the lower end of the high-pressure water chamber 5 is provided w...

Embodiment 2

[0028] Embodiment 2 Take the safety self-destruction device of fireworks and firecrackers as an example for potted flowers, the safety self-destruction device for potted flowers can be made into an integral safety self-destruction device 29, as shown in Figures 6 and 7, installed in the potted flower fireworks seat The upper end of each paper tube shell in the 23 is equipped with an integral safety self-destruction device 29, which is convenient to operate, and is safer and more reliable; Asbestos conduit 21 and fireproof conduit 10 are respectively sleeved on the ignition fuse 22 and the fast-burning fuse 3, and its principle of detonation and discharge operation are the same as

[0029] Example 1 is the same.

Embodiment 3

[0030] Embodiment 3 Take the safety self-destruction device of fireworks and firecrackers as an example for firecrackers. Because the structure of the firecrackers is special, the finished firecrackers are placed on the support 26 in the rectangular firecracker box 25, and the firecracker box 25 is divided into two parts. The safety self-destruction device is installed on one side and is closed, and the firecracker is placed on the other side. The aqueduct 11 at the lower end of the fire cap 9 of the safety self-destruction device is inserted into the firecracker box. The fast-burning fuse 3 is ignited and detonated, and the powder that is contained in the powder chamber blasts the powder chamber, and the high-pressure water is sprayed from the central hole of the fireproof cap immediately, and the high-pressure water can be shot on the main body of the firecracker along the surrounding walls of the box, thereby Self-destruct after disabling it. The disc type firecracker can ...

Abstract

A safe self-destruction device of fireworks consists of pressure valve for water injection at top cover , powder train tube , high pressure water cavity , powder column cavity , fireproof cap , powder column , quick burning train , high pressure water and fire extinguishing chemical agent . The quick burning train can ignite powder column to explode powder column cavity for jetting out high pressure water to make fireworks lose their efficiency when there is open fire on transportation or in production.

Description

technical field [0001] The invention belongs to the technical field of safety production of fireworks and firecrackers, in particular to a safety self-destruction device for fireworks and firecrackers before they are produced, stored, transported, sold and set off. Background technique [0002] In the process of production, storage, transportation, sales and discharge of existing fireworks and firecrackers, firework and firecracker explosion injury accidents caused by fire, friction, impact, static electricity, high temperature, etc. account for 90% of the fireworks and firecracker production industry. Above, the existing safety and fire prevention equipment, such as fire water, sand bags, etc., all need manual operation to play a role in fire extinguishing, but in actual work, the gunpowder will detonate immediately after encountering an open flame, and the staff have no time to operate the fire extinguishing Equipment, the signs of this accident have caused serious consequ...
