Description

探测启动泄压一体式气溶胶灭火装置及安装和灭火方法 技术领域
本发明涉及消防技术领域，具体地指一种探测启动泄压一体式气溶胶灭火装置及安装和灭火方法。
背景技术
目前，随着储能行业的不断发展，储能站以及储能电池箱体也在不断地迭代更新，从大方向来看不难得知目前的储能站以及电池PACK的内部越来越紧凑，传统的灭火装置安装在储能站或电池PACK内部往往又需要增设专门的探测装置。
部分气溶胶灭火装置采用热敏线作为探测启动结构，可以做到不增设额外的电子探测设备，但是热敏线本身具有一定的危险性以及环境污染性，因此需要相应的启动机构解决这一问题。
气溶胶灭火装置主要是通过气溶胶发生剂启动后产生大量的气体以及气溶胶灭火物质实施灭火，产生气体和灭火物质的速度取决于气溶胶发生剂的启动面积，但是随着灭火装置的体积不断变小，气溶胶灭火装置内部压力也越来越大，这种环境下气溶胶发生剂的启动面积会因为高压而发生变化，造成灭火装置内部压力骤增，因此也需要设计泄压装置来解决这一问题。
另外，现有的气溶胶灭火装置，例如CN2023200802967-一种带启动防护器的灭火装置，其启动部件均安装于壳体后端，所以在安装点火头时，需要将点火头的启动线沿着灭火剂往壳体后端穿出，才能连接启动部件，这种安装方式造成启动线穿设过程复杂，费时费力，影响了灭火装置的生产效率。
发明内容
本发明的目的在于克服上述不足，提供一种探测启动泄压一体式气溶胶灭火装置及安装和灭火方法，以解决背景技术中提出的问题。
本发明为解决上述技术问题，所采用的技术方案是：一种探测启动泄压一体式气溶胶灭火装置，包括壳体，所述壳体内设有灭火剂，所述壳体前端开设有喷口，所述灭火剂端面与点火头接触，所述点火头为无桥点火头，点火头的启动线穿出壳体前端并与压电陶瓷输出端连接，压电陶瓷安装于壳体前端的泄压槽内，压电陶瓷上方设有玻璃泡感温叩击装置。
优选地，所述玻璃泡感温叩击装置通过安装筒体与泄压槽配合，安装筒体外侧与泄压槽内侧接触，安装筒体内侧下方设置压电陶瓷。
优选地，所述玻璃泡感温叩击装置包括设于安装筒体内侧上方的撞击杆，所述撞击杆顶部与安装筒体内顶部接触，撞击杆底部设有撞击盘，所述撞击盘上表面与安装筒体顶部之间设有压缩弹簧，压缩弹簧穿设于撞击杆表面，所述撞击盘下表面与玻璃泡顶部接触，玻璃泡底部与压电陶瓷顶部接触，靠近玻璃泡区域的安装筒体侧部开设有多个镂空槽。
优选地，所述玻璃泡上侧和下侧均设有限位槽。
优选地，所述点火头包埋于点火药包内，点火药包内设有气溶胶发生剂粉末。
优选地，所述灭火剂顶面与喷口之间还设有冷却剂；所述灭火剂为气溶胶发生剂粉末或气溶胶发生剂粉末压制而成的药柱结构。
优选地，所述冷却剂上侧和下侧均设有隔网，位于下侧的隔网底部与灭火剂顶面之间还设有支撑件。
优选地，所述壳体前端与前盖螺纹配合，前盖上开设喷口和泄压槽，泄压槽内还设有用于对压电陶瓷限位的台阶，喷口表面设有膜片。
本发明还公开上述探测启动泄压一体式气溶胶灭火装置的安装方法，它包括如下步骤：
S1：打开壳体前端的前盖，向壳体内装入灭火剂，然后将点火头安装到灭火剂顶面，并向上牵引出启动线，然后在灭火剂顶部设置冷却剂；
S2：将启动线上端从前盖的泄压槽向上穿出，与安装在泄压槽内的压电陶瓷输出端连接；
S3：将前盖与壳体前端安装固定，在压电陶瓷外表面与泄压槽内表面之间的缝隙插装好安装筒体，然后安装好安装筒体上侧的玻璃泡感温叩击装置。
本发明还公开上述探测启动泄压一体式气溶胶灭火装置的灭火方法，它包括如下步骤：
S1：当火情发生时，玻璃泡通过镂空槽感受高温而膨胀破碎，从而解除对撞击盘的限位作用，在压缩弹簧弹力的作用下，撞击盘向下移动并撞击压电陶瓷；
S2：压电陶瓷受撞击后启动而产生感应电流，通过启动线传导至点火头使其工作，从而引燃灭火剂；
S3：灭火剂燃烧而产生灭火物质，然后经过冷却剂后从喷口位置喷出，进行灭火过程。
本发明的有益效果：
本发明通过设置于泄压槽所在区域的安装筒体、压电陶瓷和玻璃泡感温叩击装置，使得探测、启动和泄压功能集成于一个较小区域，其结构精简、探测灵敏、启动安全；在压力异常骤增的情况下，压电陶瓷及安装筒体能够及时喷出而露出泄压槽，实现泄压过程；并且由于 在安装过程中，启动线上端从前盖的泄压槽向上穿出，与安装在泄压槽内的压电陶瓷输出端连接，这种启动线穿设过程简单，同时本发明的启动线还在泄压过程中承担着保护线的作用，防止压电陶瓷及安装筒体喷出而造成安全事故。

具体实施方式
下面结合附图和具体实施例对本发明作进一步的详细描述。
如图1和2所示，一种探测启动泄压一体式气溶胶灭火装置，包括壳体1，所述壳体1内设有灭火剂2，所述壳体1前端开设有喷口3，所述灭火剂2端面与点火头4接触，所述点火头4为无桥点火头，点火头4的启动线4.1穿出壳体1前端并与压电陶瓷5输出端连接，压电陶瓷5安装于壳体1前端的泄压槽6内，压电陶瓷5上方设有玻璃泡感温叩击装置7。
优选地，所述玻璃泡感温叩击装置7通过安装筒体8与泄压槽6配合，安装筒体8外侧与泄压槽6内侧接触，安装筒体8内侧下方设置压电陶瓷5。在本实施例中，安装筒体8可以起到三个作用，一是可以方便玻璃泡感温叩击装置7在泄压槽6内的安装过程，二是方便对压电陶瓷5进行限位，三是方便在泄压过程中，压电陶瓷5和安装筒体8能够脱离泄压槽6，从而露出泄压通道。
优选地，所述玻璃泡感温叩击装置7包括设于安装筒体8内侧上方的撞击杆7.1，所述撞击杆7.1顶部与安装筒体8内顶部接触，撞击杆7.1底部设有撞击盘7.3，所述撞击盘7.3上表面与安装筒体8顶部之间设有压缩弹簧7.4，压缩弹簧7.4穿设于撞击杆7.1表面，所述撞击盘7.3下表面与玻璃泡7.5顶部接触，玻璃泡7.5底部与压电陶瓷5顶部接触，靠近玻璃泡7.5区域的安装筒体8侧部开设有多个镂空槽7.2。在本实施例中，当火情发生时，玻璃泡7.5通过镂空槽7.2感受高温而膨胀破碎，从而解除对撞击盘7.3的限位作用，在压缩弹簧7.4弹力的作用下，撞击盘7.3向下移动并撞击压电陶瓷5；压电陶瓷5受撞击后启动而产生感应电流，通过启动线4.1传导至点火头4使其工作，从而引燃灭火剂2，完成启动过程。
优选地，所述玻璃泡7.5上侧和下侧均设有限位槽7.6。通过限位槽7.6可以对玻璃泡7.5进行限位，防止其发生横向晃动。
所述点火头4包埋于点火药包12内，点火药包12内设有气溶胶发生剂粉末。本实 施例中点火头4采用无桥点火头，由于无桥点火头的两根点火导线之间留有一定的间隙，通过提供一定的电流或感应电流以后会发生跳弧现象而启动接触的引燃药，在本实施例中点火药包12作为引燃药，其将点火头4包埋其中，点火头4启动后点燃点火药包12内的气溶胶发生剂，从而迅速产生热量而引燃附近的灭火剂2，其大大提高了点火头4启动成功的概率。
优选地，所述灭火剂2顶面与喷口3之间还设有冷却剂9；所述灭火剂2为气溶胶发生剂粉末或气溶胶发生剂粉末压制而成的药柱结构。通过冷却剂9可以对灭火剂2点燃产生的高温灭火物质进行降温，防止从喷口3喷出的温度过高。在本实施例中，灭火剂2为气溶胶发生剂，可以采用两种状态，一种为粉末状，其燃烧较为剧烈，产生气体速度快，另一种采用压制而成的药柱结构，其燃烧较为平稳，产生气体速度平稳，在实际生产中，可根据实际情况来选择。
优选地，所述冷却剂9上侧和下侧均设有隔网10，位于下侧的隔网10底部与灭火剂2顶面之间还设有支撑件11。在本实施例中，冷却剂9本身为颗粒状，所以通过上下两侧的隔网10可以起到限位作用，在本实施例中隔网10与壳体1内壁之间并没有固定连接，而只是与壳体1内壁之间保持接触状态。另外支撑件11可以防止下侧的隔网10直接压迫点火头4所在区域，防止对其点火过程造成影响而导致点火失败。
优选地，所述壳体1前端与前盖1.1螺纹配合，前盖1.1上开设喷口3和泄压槽6，泄压槽6内还设有用于对压电陶瓷5限位的台阶，喷口3表面设有膜片。在泄压槽6内设置台阶后，可以方便压电陶瓷5的安装过程，同时台阶顶面也可以对安装筒体8底部进行限位；喷口3表面设置膜片后，可以在灭火装置正常储运过程中，防止空气中的水分通过喷口3进入到壳体1内导致灭火剂2吸潮，另外在灭火过程中，壳体1内部气压增大时，容易冲破膜片，不影响喷口3的正常喷放过程。
本发明还公开上述探测启动泄压一体式气溶胶灭火装置的安装方法，它包括如下步骤：
S1：打开壳体1前端的前盖1.1，向壳体1内装入灭火剂2，然后将点火头4安装到灭火剂2顶面，并向上牵引出启动线4.1，然后在灭火剂2顶部设置冷却剂9；
S2：将启动线4.1上端从前盖1.1的泄压槽6向上穿出，与安装在泄压槽6内的压电陶瓷5输出端连接；
S3：将前盖1.1与壳体1前端安装固定，在压电陶瓷5外表面与泄压槽6内表面之间的缝隙插装好安装筒体8，然后安装好安装筒体8上侧的玻璃泡感温叩击装置7。
本发明还公开上述探测启动泄压一体式气溶胶灭火装置的灭火方法，它包括如下步骤：
S1：当火情发生时，玻璃泡7.5通过镂空槽7.2感受高温而膨胀破碎，从而解除对撞击盘7.3的限位作用，在压缩弹簧7.4弹力的作用下，撞击盘7.3向下移动并撞击压电陶瓷5；
S2：压电陶瓷5受撞击后启动而产生感应电流，通过启动线4.1传导至点火头4使其工作，从而引燃灭火剂2；
S3：灭火剂2燃烧而产生灭火物质，然后经过冷却剂9后从喷口3位置喷出，进行灭火过程。
本发明公开上述探测启动泄压一体式气溶胶灭火装置的泄压方法，它包括如下步骤：
S1：在灭火过程中，若壳体1内压力异常而发生骤增现象时，安装筒体8及压电陶瓷5在气压作用下向上脱离泄压槽6；
S2：气体从泄压槽6处喷出，实现泄压功能；
S3：压电陶瓷5向上移动过程中通过启动线4.1带动点火头4上移，点火头4上移至接触下侧的隔网10时，带动隔网10一起上移；
S4：隔网10向上移动而逐渐压缩冷却剂9，逐渐压缩的冷却剂9对隔网10形成缓冲，隔网10停止移动后，点火头4也受阻挡而停止移动，进而通过启动线4.1牵拉压电陶瓷5停止移动，防止压电陶瓷5及安装筒体8喷出而造成安全事故。在这一步骤中，逐渐压缩的冷却剂9对隔网10形成缓冲，可以防止隔网10速度移动过快而拉断启动线4.1。
上述的实施例仅为本发明的优选技术方案，而不应视为对于本发明的限制，本申请中的实施例及实施例中的特征在不冲突的情况下，可以相互任意组合。本发明的保护范围应以权利要求记载的技术方案，包括权利要求记载的技术方案中技术特征的等同替换方案为保护范围。即在此范围内的等同替换改进，也在本发明的保护范围之内。

  9. 一种权利要求1至8任一项所述探测启动泄压一体式气溶胶灭火装置的安装方法，其特征在于：它包括如下步骤：
    S1：打开壳体(1)前端的前盖(1.1)，向壳体(1)内装入灭火剂(2)，然后将点火头(4)安装到灭火剂(2)顶面，并向上牵引出启动线(4.1)，然后在灭火剂(2)顶部设置冷却剂(9)；
    S2：将启动线(4.1)上端从前盖(1.1)的泄压槽(6)向上穿出，与安装在泄压槽(6)内的压电陶瓷(5)输出端连接；
    S3：将前盖(1.1)与壳体(1)前端安装固定，在压电陶瓷(5)外表面与泄压槽(6)内表面之间的缝隙插装好安装筒体(8)，然后安装好安装筒体(8)上侧的玻璃泡感温叩击装置(7)。
  10. 一种权利要求1至8任一项所述探测启动泄压一体式气溶胶灭火装置的灭火方法，其特征在于：它包括如下步骤：
    S1：当火情发生时，玻璃泡(7.5)通过镂空槽(7.2)感受高温而膨胀破碎，从而解除对撞击盘(7.3)的限位作用，在压缩弹簧(7.4)弹力的作用下，撞击盘(7.3)向下移动并撞击压电陶瓷(5)；
    S2：压电陶瓷(5)受撞击后启动而产生感应电流，通过启动线(4.1)传导至点火头(4)使其工作，从而引燃灭火剂(2)；
    S3：灭火剂(2)燃烧而产生灭火物质，然后经过冷却剂(9)后从喷口(3)位置喷出，进行灭火过程。
