本实用新型是一种模拟爆竹连接地逐个点燃和闪光爆炸的机电装置。如图一所示,它主要由装有扬声器(9)的四面体顶罩(8),开有多个透光孔和悬挂爆竹孔(11)的主体圆筒和圆筒形的底罩(3),以及圆筒内装有闪光灯和聚光小灯的升降光源盘(5),拾音磁头,录有爆炸声的环形磁带(13),低速电动机(12)和控制电路板(2)组成。并设有多个中心穿过光纤与真实爆竹相似的模拟爆竹悬挂于圆筒外,它能逼真的模拟爆竹连续燃放景象,具有安全可靠,无污染,能反复使用等优点。 说明

本实用新型是一种模拟爆竹点燃和爆炸,特别是模拟多个爆竹逐个点燃和爆炸的声、光、机、电装置。

众所周知,爆竹主要由炸药制成。爆炸时会产生大量烟雾和碎屑,不但污染环境,影响卫生而且燃放不当还会对人畜和财产、物品产生伤害和破坏,甚至导致火灾。大量燃放爆竹还会耗去不少资源。现有的电子爆竹虽然能产生各种声响和光学效果,但离爆竹燃放的真实情景相差甚远,达不到应有的气氛。

本实用新型旨在设计一种对人畜、财产、环境安全物害,能够反复使用,逼真地模拟爆竹燃放的机电装置。

本实用新型的电子爆竹是充分论证了其制造和使用上的经济性之后设计的。图1为本实用新型的结构图。其底部为园筒形的底罩(3),里面安装有控制电路板(2)和低速电动机(12),它们均由底罩上面的安装盘(4)固定,另外还设有电池盒,变压器和220V电源插座,使本实用新型可以由电池或市电供电。在底罩外面还设有点火引信(16)及点火指示器(17),用以触发本实用新型。上部是一个三角形四面体的顶罩(8),里面朝外装有扬声器(9)。中部是本实用新型的主体外壳——园筒,园筒在各个方向上开有多个透光孔和多个垂直排列用于悬挂爆竹的小孔——悬挂爆竹孔(11),模拟爆竹可由塑料或者其它材料做成,其大小形状与真实爆竹相似,模拟爆竹中心穿过一根光纤,若干根光纤被一个具有台阶的塑料套管所束缚由外向里塞入悬挂爆竹孔内。光纤的末端敷有散光聚合物做为模拟爆竹引信。园筒内设有闪光灯和对准悬挂爆竹孔的聚光灯泡,它们均安装在升降光源盘的空间里。为使其能上、下往返运动,升降光源盘中心孔有阴螺纹,与之啮合的丝杆(7)通过连接套筒与穿过安装盘(4)并固定在安装盘下表面的低速电动机的转轴相接,如图1和图2,连接套筒又是录有爆竹爆炸声响信号的环形磁带走带的传动轴。安装盘的四周有六只动滑轮,用以传动磁带和增加其有效长度。放音磁头紧贴磁带拾取音响信号。本实用新型的控制电路,如图3所示。由传感器触发电路、延时器和定时器电路、振荡器、倍压整流、声响放大电路、高压闪光电路和声控光同步触发电路组成,并设有整流电源电路。

本实用新型的工作过程如下,接通电源后进入等待触发阶段,点火触发后传感器触发电路产生一信号送至延迟器,延迟2~3秒后,定时器开关闭合,整机电路进入工作状态,聚光灯泡和低速电动机导通,聚光灯泡对准的某一组爆竹的光纤始端,使光纤末端发亮模拟爆竹点燃的景象。低速电动机转动牵动磁带,放音磁头拾取声响信号送入声响放大电路去推动扬声器,同时声光同步触发电路触发高压闪光电路使闪光灯闪烁以产生爆竹爆炸的光、声效果。低速电动机转动同时带动丝杆(7)旋转,升降光源盘移动,使聚光灯泡移向下一组爆竹的光纤始端,模拟爆竹的逐个点燃。整机工作时间由定时器控制,一般设置在1~2分钟。到达设定时间后整机停止工作,重新进入等待触发状态。

为使各个方向均能感受到爆竹的逐个点燃和爆炸,本实用新型在顶罩的三个侧面均装有扬声器,园筒四周都开有悬挂爆竹孔,设有四个聚光灯泡分别对准四个方向的悬挂爆竹孔,两只高压闪光灯已足够使园筒壁四周上的透光孔射出闪烁的光。

本实用新型能够逼真的体现爆竹逐个点燃和爆炸的动态、表现,同时不会污染环境、安全可靠,并且能够反复使用节省资源。

附图1为本实用新型的构造图。图中,1——220V电源插座;2——控制电路板;3——底罩;4——安装盘;5——升降光源盘;6——连接套筒;7——丝杆;8——顶罩;9——扬声器;10——提手;11——悬挂爆竹;12——低速电动机;13——环形磁带;14——变压器;15——电池盒;16——点火引信;17——点火指示器。

附图2为图1中的N-N方面上的剖视图,即磁带传动装置结构图。

附图3是控制电路板的电原理图。

本实用新型的最好实施例是整体高度在650mm左右,外园筒直径150mm左右。整个外壳是一个声学共鸣箱由塑料做成,园筒由具有一定机械强度、不透明塑料制做的两个半园筒相嵌而成,其内壁开有两条垂直方向的沟槽使升降光源盘的两个凸键在其间上、下滑动。

为简化控制电路,低速电动机应具有在转动受阻后能自行反转的功能。

底罩上设有点火引信由热敏电阻做成,可用任何具有一定温度的点火用具触发整机,发光二极管做为点火触发指示器。模拟爆竹引信采用光导纤维。

整机装配顺序由下向上,由里到外。几个主要构件的连接用螺钉固紧。

Hello there! This is kind of off topic but I need some guidance from an established blog. Is it tough to set up your own blog? I'm not very techincal but I can figure things out pretty quick. I'm thinking about creating my own but I'm not sure where to start. Do you have any ideas or suggestions? Cheers|

Today, I went to the beachfront with my children. I found a sea shell and gave it to my 4 year old daughter and said "You can hear the ocean if you put this to your ear." She put the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear. She never wants to go back! LoL I know this is totally off topic but I had to tell someone!|
