Description

一种热成像靶 技术领域
本发明涉及一种射击瞄准用的靶，特别涉及一种适用于热成像瞄准镜射击用的热成像靶。
 背景技术
瞄准镜，自发明以来就因为它的准确性使它在比赛、狩猎和军事活动中得到广泛运用，而靶，或称靶纸，则是瞄准镜在使用过程中校准和检验的重要工具，靶纸简单易用、造价低廉、同时靶纸上的环都有标准的直径和大小，可以准确测量和体现射击结果。
 技术问题
随着技术的发展，热成像瞄准镜更是因为它能在黑暗环境中发现并命中目标而在狩猎和军事活动中受到特殊喜爱，但是，作为瞄准镜的一种，热成像瞄准镜却没有简单易用的靶纸，因为热成像瞄准镜看不见普通靶纸上的颜色或者色环，热成像瞄准镜只能看到靶纸上的温度差，而普通靶纸由于材质相同，靶纸上的环或靶环之间几乎没有温度差，对于热成像瞄准镜来说是几乎看不见的，从而也就无法实现它校准和检验热成像瞄准镜的功能。在现有技术的使用中，人们都是通过因地制宜的方法来实现热成像瞄准镜的校准和检验功能，有人用电加热，有人用火加热小铁块来做靶心，有人通过贴金属胶带在纸皮上然后在太阳底下暴晒从而获得目标靶上的温度差，这些方法虽然能用，但是它们要么不简单易用、要么造价不低廉从而不经济实用，要么由于材料需要重复利用，使用后还要走很远的路去回收，比如电加热和铁块等，要么由于目标靶的温度持续不了足够长的时间需要重复加热，更是谈不上准确地测量和体现射击结果。
因此，现有技术有待发展。
 技术解决方案
为了解决上述问题，本发明提出一种热成像靶，该靶具有持续时间足够长的温度差能被热成像瞄准镜清晰看见，且结构简单、使用方便、造价低廉，适用于推广应用。
本发明是通过以下技术方案实现的：
一种热成像靶，用于射击训练，其中，包括隔热层、导热层、导流层、底层以及自热包；
所述导热层与底层的边缘密封连接，并在顶端开口而形成口袋状结构；
所述自热包放置于口袋内，自热包内设置有自热材料用于产生热量；
所述导流层在口袋内支撑在导热层与底层之间并形成交叉连通的散热腔道，用于引导自热包产生的热量在口袋内交叉流动；
所述隔热层贴设于导热层的外表面；
所述隔热层的导热性能低于导热层的导热性能，以使得热量在传导过程中在导热层与隔热层上形成温度差。
其中，所述隔热层为相互间隔的环状圈，或为人物形状，或为动物形状。
其中，所述导流层为设置在口袋内上下相互交错排列的多个导流柱，每一导流柱的两端分别抵接在导热层与底层上。
其中，所述导流柱将导热层与底层之间撑起1～4mm的间隔。
其中，所述导热层与底层为尺寸匹配的方形薄膜或方形薄片结构。
其中，所述底层在非开口位置的边缘设置有粘合区，所述导热层与底层的粘合区粘合。
其中，所述导热层为导热材质。
其中，所述隔热层为隔热保温材质。
其中，所述底层为隔热保温材质。
其中，所述隔热层表面的颜色与导热层表面的颜色不同以形成人眼易辨识的颜色反差。
本发明的热成像靶，通过设置隔热层、导热层、导流层、底层以及自热包组成的结构，巧妙地使用现成的食品自热包做发热源，方便经济且没有明火安全隐患，导热层和底层形成的口袋状结构尽可能地把自热包产生的热量的保持在口袋状结构里以被用于加热导热层，导流层的导流柱的相互交错的排列方式使自热包产生的热气在口袋状结构内上升的过程中交叉流动，以避免靶纸弹孔上方的部分出现冷却区域，从而保证使用效果，隔热层贴设于导热层的外表面，且隔热层的导热性能低于导热层的导热性能，这样使得自热包产生的热量传导过程中会在导热层与隔热层形成温度差，而当隔热层设计成相互间隔的环状圈时，则会因温度差在导热层上形成一圈一圈的能被热成像瞄准镜看到的靶环。
 有益效果
本发明的热成像靶可以快速部署且简单易用、结构简单且造价低廉从而经济实惠、靶纸上的环之间有足够的温度差能被热成像瞄准镜清晰看见，且这种温度差能够持续足够长的时间来进行射击、靶纸上的环都有标准的直径和大小以实现精确校准和检验，同时靶纸上的环之间还有颜色反差，普通的瞄准镜也能使用，极大地提升成像瞄准镜校准和检验的方便度。

 本发明的最佳实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
请参考图1至图2，为本发明提供的一种热成像靶100，用于射击训练，包括隔热层1、导热层2、导流层3、底层4以及自热包5。
如图3所示，本发明的导热层2与底层4的边缘密封连接，并在顶端开口6而形成口袋状结构8。导热层2与底层4的边缘可以采用胶水密封，或者使用热熔密封。导热层2与底层4形成口袋状结构8后用于在口袋内容置自热包5，并将自热包5产生的热量保持在口袋内，同时，顶端的开口6用于将口袋内热膨胀后的气体排出，防止口袋内压力过高而破裂。
优选地，本发明热成像靶100的导热层2与底层4为尺寸匹配的方形薄膜或方形薄片结构。即两者大小，形状匹配，且为方形薄膜或方形薄片结构，易于获取或者易于加工。
进一步地，如图3和图5所示，本发明热成像靶100的底层4在非开口6位置的边缘设置有粘合区41，所述导热层2与底层4的粘合区41粘合。粘合区41的设置便于导热层2与底层4的粘合固定。
如图4所示，本发明热成像靶10的自热包5放置于口袋内，自热包5内设置有自热材料用于产生热量。自热包5产生的热量用于加热导热层2。
本发明的自热包5直接使用现有的食品自热包做发热源，方便经济且由于不用明火加热所有没有安全隐患。
自热包5由自热材料做成，自热又称无火加热，它通过自热材料和水或空气中的氧气产生化学反应从而产生大量的热量，如目前最常用的自热食品的自热材料的主要成分是镁粉，它和水产生化学反应产生热量，它的化学方程式表示为Mg + 2H2O = Mg(OH)2 + H2 [+ 热量(q)]，自热包被广泛用于自热食品行业中。
如图5所示，本发明热成像靶100的导流层3在口袋内支撑在导热层2与底层4之间并形成交叉连通的散热腔道7，用于引导自热包5产生的热量在口袋内交叉流动。
导流层3支撑在导热层2和底层4之间形成散热腔道7，使得导热层2和底层4之间保持一定的距离便于自热包5产生的热气在导热层2和底层4之间流通，同时交叉连通的散热腔道7，使得热气在口袋状结构8里交叉流动，即使口袋状结构8被子弹射穿，口袋状结构8内弹孔上方的空间仍有热气流通，避免了靶纸弹孔上方的部分出现冷却区域，保证本发明的热成像靶的使用效果。
如图1和图2所示，本发明热成像靶100的隔热层1贴设于导热层2的外表面，同时，隔热层1的导热性能低于导热层2的导热性能，这样以使得热量在传导过程中在导热层1与隔热层2上形成温度差。
优选地，本发明的导热层2为导热性能好的导热材质,如导热塑料膜或金属箔，本发明的隔热层1为隔热保温材质,如导热性能差但是隔热性能好的隔热保温塑料。这样，自热包5产生的热量能迅速在导热层2表面传导，但是由于隔热层1的隔热作用，隔热层1外表面的温度和导热层2表面的温度产生差异，这样在用热成像瞄准镜观察时，导热层2没有贴设隔热层1的区域和贴设了隔热层1的区域会形成温差而被热成像瞄准镜看到。
作为一种实施方式，本发明热成像靶100的隔热层1为相互间隔的环状圈11。相互间隔的环状圈11使得本发明的热成像靶100用热成像瞄准镜观看时可以看到标准的靶圈。
本发明的热成像靶100在使用时，自热包5产生的热气在口袋状结构8内上升的过程中被导流层3分隔使其交叉流动，同时由于导热层2良好的导热性能，使得导热层2的温度均匀升高，又由于隔热层1粘贴于导热层2且它的导热性能和导热层2完全不同，从而使得由若干相互间隔的环状圈11组成的隔热层1和底下的导热层2形成相互间隔且温度反差较大的环状区域，热成像瞄准镜正是用于感知环境的温度差的，这些由隔热层1和导热层2组成的相互间隔且温度反差较大的环状区域就像普通靶纸的环一样被热成像瞄准镜看到。
同时，导热层2和底层4形成的口袋状结构8可以尽可能地把自热包产生的热量的保持在口袋状结构8里并均匀扩散以使热量被用来加热导热层2，轻微的热量就可以使靶纸上由隔热层1和导热层2组成的相互间隔的环之间产生足够的温度差使它可以被热成像瞄准镜看到，一个常用的自热包可以使本发明的热成像靶保持30至90分钟的使用时间，从而使靶纸有足够长的时间被用来进行射击。
优选地，本发明热成像靶100的底层4也采用隔热保温材质如隔热保温塑料，这样能尽量保持住口袋内的热量，延长热成像靶的可使用时长。
具体地，如图2所示，本发明热成像靶100的导流层3为设置在口袋内上下相互交错排列的多个导流柱31，每一导流柱31的两端分别抵接在导热层2与底层4上。如图5所示，上下相互交错排列的多个导流柱31将口袋内的空腔分成交叉连通的散热腔道7。导流柱31的两端可以采用胶水或热熔的方式粘贴在导热层2与底层4上。
即本发明的多个导流柱31从自热包的上方交错排列一直延申到口袋的开口6处。多个导流柱31将自热包5产生的热量交叉散开，避免热量垂直上升，这样，当热成像靶100被子弹射穿时，口袋状结构8内弹孔上方的空间仍可由旁边的交叉连通的散热腔道7内的热气流入而使弹孔上方热量还是能均匀分布，避免了靶纸弹孔上方的部分出现冷却区域，从而保证本发明的热成像靶的使用效果。
优选地，本发明的导流柱31将导热层2与底层4之间撑起1～4mm的间隔。1～4mm的间隔使得热传导效果最佳。
可以理解，本发明热成像靶100的隔热层1的形状不一定只被限定为相互间隔的环状圈11，还可以按实际需要被做成人物形状，或为动物形状等。
进一步地，本发明热成像靶100的隔热层1表面的颜色与导热层2表面的颜色不同以形成人眼易辨识的颜色反差。隔热层1的颜色和导热层2的颜色反差虽然热成像瞄准镜看不到，但是却可以被普通瞄准镜使用或用于人眼快速读取环值。即本发明的热成像靶100也可以用于普通瞄准镜的瞄准。
本发明的热成像靶100在使用时，撕开自热包5的密封，如果是和水反应的自热包5还要从口袋状结构8的开口6注入一定量的水，自热包5产生的热气在口袋状结构8内上升的过程中被导流层3的导流柱31分隔使其交叉流动，同时由于导热层2良好的导热性能，使得导热层2的温度均匀升高，又由于隔热层1粘贴于导热层2且它的导热性能和导热层2完全不同，从而使得由若干相互间隔的环状圈11组成的隔热层1和底下的导热层2形成相互间隔且温度反差较大的环状区域，这些由隔热层1和导热层2组成的相互间隔且温度反差较大的环状区域就像普通靶纸的环一样被热成像瞄准镜看到，靶纸上的环之间有足够的温度差能被热成像瞄准镜清晰看见。
综上所述，本发明的热成像靶克服了现有技术中存在的缺点，通过巧妙地使用现成的食品自热包5做发热源，方便经济且由于不用明火加热所有没有安全隐患，通过导热层2和底层4形成的口袋状结构8尽可能地把自热包5产生的热量的保持在口袋状结构8里以被用于加热导热层2；导流层3的导流柱31的相互交错的排列方式使自热包5产生的热气在口袋状结构8内上升的过程中交叉流动以避免靶纸弹孔上方的部分出现冷却区域从而保证使用效果，隔热层1和导热层2组成的相互间隔的环状区域设计产生相互之间有温度差从而能被热成像瞄准镜看到的靶环。
本发明的热成像靶100可以快速部署且简单易用、结构简单且造价低廉从而经济实惠、靶纸上的环之间有足够的温度差能被热成像瞄准镜清晰看见，且这种温度差能够持续足够长的时间来进行射击、靶纸上的环都有标准的直径和大小以实现精确校准和检验，同时靶纸上的环之间还有颜色反差，普通的瞄准镜也能使用，极大地提升成像瞄准镜校准和检验的方便度。
尽管上面已经示出和描述了本发明的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本发明的限制，本领域的普通技术人员在不脱离本发明的原理和宗旨的情况下在本发明的范围内可以对上述实施例进行变化、修改、替换和变型。
