Abstract
A sound control time delay firework comprises firecrackers and a blasting fuse. The blasting fuse is connected with an electric heating wire. The electric heating wire is installed in an igniter. The igniter is connected with a cable. The cable is connected with a sound sensor. The sound sensor is connected with a main control plate. The main control plate is connected with a storage battery through a power line. The main control plate is connected with a control button through a control line. The sound sensor, the main control plate, the power line and the storage battery are installed in a mainframe. The firecrackers and the mainframe are installed on a ground. According to the sound control time delay firework, ignition can be delayed, the control button is pressed to ignite the firecrackers when a user leaves for a certain distance, the sound control time delay firework is further controlled by the sound sensor after the control button is pressed so that in a certain scope, each firecracker is shot off in turn, the firework is ignited after the user is away from the firecrackers, and therefore igniting time is prolonged, personal safety is ensured, orderly setting is achieved, and a human body is prevented from being hurt by noise.
Description
One, technical field
The utility model relates to a kind of safety-type pyrotechnics, relates in particular to a kind of sound-controlled delay pyrotechnics that can exclusively singly put, be perfectly safe.
Two, background technology
People can hurt oneself when using lighter to light fireworks and firecrackers, often hear someone because the firecracker of setting off fireworks is improper and injured in news report, even dead, particularly the New Year's Eve puts fireworks and firecrackers, and several thousand firecrackers are put simultaneously, and is very dangerous, too loudly, noise also has injury to human body.
Three, utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of sound-controlled delay pyrotechnics that can exclusively singly put, be perfectly safe is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of sound-controlled delay pyrotechnics, comprise firecracker and fuse cord, fuse cord connects heating wire, heating wire is installed in the igniter, the igniter connecting cable, cable connects sound transducer, sound transducer connects master control borad, master control borad is connected with storage battery by power line, master control borad is connected with control button by control line, sound transducer, master control borad, power line, storage battery are installed in the main frame, and firecracker and main frame are installed on the ground.
The beneficial effects of the utility model are, can delayed firings, when treating that the people leaves certain distance, press again the control button igniting, and after pressing control button, also to be subject to the control of sound transducer, so within the specific limits, can only banish by every firecracker wheel.The utility model is an instrument that just begins to light a fire after the people is away from fireworks and firecrackers, not only can prolong the duration of ignition, protection people's safety, and can accomplish to set off in order, do not allow noise to the human injury.
Four, description of drawings
Below in conjunction with drawings and Examples, further specify the structure and characteristics of the utility model sound-controlled delay pyrotechnics, in the accompanying drawing:
Fig. 1 is the structure chart of embodiment one of the present utility model.
Among the figure: 1. firecracker, 2. fuse cord, 3. heating wire, 4. cable, 5. sound transducer, 6. master control borad, 7. power line, 8. control line, 9. control button, 10. storage battery, 11. ground, 12. igniters, 13. main frames.
Five, the specific embodiment
In the embodiment shown in fig. 1, be provided with firecracker (1), fuse cord (2), heating wire (3), cable (4), sound transducer (5), master control borad (6), power line (7), control line (8), control button (9), storage battery (10), ground (11), igniter (12), main frame (13).
Implement sound-controlled delay pyrotechnics of the present utility model, comprise firecracker (1) and fuse cord (2), fuse cord (2) connects heating wire (3), heating wire (3) is installed in the igniter (12), igniter (12) connecting cable (4), cable (4) connects sound transducer (5), sound transducer (5) connects master control borad (6), master control borad (6) is connected with storage battery (10) by power line (7), and master control borad (6) is connected with control button (9) by control line (8).Sound transducer (5), master control borad (6), power line (7), storage battery (10) are installed in the main frame (13).Firecracker (1) and main frame (13) are installed on the ground (11).
Implement sound-controlled delay pyrotechnics of the present utility model, in the circuit with one section heating wire access storage battery, behind the plugged, heating wire produces heat, and along with the prolongation of time, the heating wire temperature raises gradually, reach the ignition point of blasting fuse after, fire off crackers.Simultaneously sound transducer is installed in main frame, when other firecracker setoffs are arranged, has the huge sound, at this moment sound transducer can cut off circuit, waits when not having sound again automatic processing circuit.
The utility model utilizes the fuel factor of electric current to come to begin igniting for the firecracker igniting after the people arrives safe zone, has ensured people's safety, and sound transducer of adjunction is accomplished to set off in order between igniter and master control borad.
Claims (3)
