Description

挡烟闭火防蔓延智能窒息控火系统 技术领域
本申请涉及防火设备技术领域，尤其涉及一种挡烟闭火防蔓延智能窒息控火系统。
背景技术
火灾是一种会给人们造成巨大财产损失和人身伤害的恶性灾害，为防火和灭火，人们申请和制造了许许多多的设备，它们在防火和灭火中起着重要的作用。
其中，对于防火卷帘门来说，其主要用于大型超市(大卖场)、大型商场、大型专业材料市场、大型展馆、厂房、仓库等有消防要求的公共场所。当火警发生时，防火卷帘门在消防中央控制系统的控制下，按预先设定的程序自动放下，从而起到阻止火焰向其他范围蔓延的作用，为实施消防灭火争取宝贵的时间。因此，防火卷帘门在消防中起到十分重要的作用。
但是，现有的防火卷帘门主要用于大空间的场合中，其作用只是阻止火势进一步蔓延，并没有窒息灭火的功能；并对于小空间的房间而言，由于火灾都是从单个房间为起火点，故防火卷帘门并不能将火灾阻拦于小空间的单个房间内，无法使起火的单个房间窒息灭火。
因此，急需要一种挡烟闭火防蔓延智能窒息控火系统来克服上述的缺陷。
申请内容
本申请的目的在于提供一种挡烟闭火防蔓延智能窒息控火系统，应用于小空间的房间，对着火的小空间的房间具有挡烟、闭火、防蔓延及自动窒息灭火的作用。
为实现上述的目的，本申请提供一种挡烟闭火防蔓延智能窒息控火系统，包括卷帘组件及用于根据房间内环境变化而选择性地释放所述卷帘组件的自动释放装置。所述卷帘组件分别安装于房间中与门口相对应的墙体及与窗口相对应的墙体上，所述卷帘组件包含防火幕帘、用于将所述防火幕帘卷绕成卷状的卷绕轴及装配于所述防火幕帘之展开端上的配重块，所述卷绕轴可转动地装配于所述墙体上，所述配重块在所述自动释放装置释放所述卷帘组件下带动所述防火幕帘自由展开及落下，以关闭所述门口和窗口。
较佳地，所述自动释放装置包含温控释放装置。
较佳地，所述温控释放装置为一在房间内的温度变化达到阈值时自动熔断的温控熔断丝，所述温控熔断丝的一端与所述配重块或防火幕帘的展开端固定，所述温控熔断丝的另一端与所述墙体固定；或者，所述温控熔断丝将所述配重块和防火幕帘捆绑固定。
较佳地，所述窗口所对应的温控熔断丝的阈值小于所述门口所对应的温控熔断丝的阈值。
较佳地，所述自动释放装置包含用于感测房间内环境变化的传感器、用于接受所述传感器所反馈信息的控制器及用于对所述卷帘组件锁定的执行机构，所述控制器分别与所述传感器和执行机构电性连接，所述控制器根据所述传感器的反馈信息去控制所述执行机构做释放所述卷帘组件的运动。
较佳地，所述传感器为温度传感器或烟雾传感器。
较佳地，所述窗口所对应的传感器的预设值小于所述门口所对应的传感器的预设值。
较佳地，本申请的挡烟闭火防蔓延智能窒息控火系统还包括用于对所述配重块及防火幕帘中至少一者的运动提供导引的上下轨道，所述上下轨道装配于所述墙体上，所述上下轨道位于所述卷绕轴的正下方，所述配重块及防火幕帘中至少一者的侧边嵌入所述上下轨道并与该上下轨道间隙配合。
较佳地，本申请的挡烟闭火防蔓延智能窒息控火系统还包括与所述墙体装配连接的支座，所述卷线轴伸出所述防火幕帘的端部可转动地装配于所述支座 上。
较佳地，所述配重块为条形结构，所述配重块与所述防火幕帘之展开端的端部固定连接。
与现有技术相比，由于卷帘组件分别安装于房间中与门口相对应的墙体及与窗口相对应的墙体上，且卷帘组件包含防火幕帘、用于将防火幕帘卷绕成卷状的卷绕轴及装配于防火幕帘之展开端上的配重块，卷绕轴可转动地装配于墙体上，并结合自动释放装置，由自动释放装置根据房间内环境变化(例如温度变化和/或烟雾变化)而选择性地释放卷帘组件，故卷帘组件的释放更精准可靠；同时，在自动释放装置释放卷帘组件时，配重块则直接带动防火幕帘自由展开及落下，以同时关闭着火房间的门口和窗口，从而使着火的小空间的房间处于封闭状态，除起到挡烟、闭火和防蔓延作用外，更具有窒息灭火作用，这是由于着火的房间被封闭，外界氧气没法通过门口和窗口往房间内补充，且着火的房间所产生的二氧化碳无法排出而于房间内累积，二氧化碳本身具有灭火作用，真正达到了自动智慧窒息灭火的效果。另，正由于防火幕帘的自由展开及落下是由配重块的重力所带动，故简化用于驱使防火幕帘展开及落下的结构，并确保防火幕帘展开及落下的可靠性。此外，本申请的挡烟闭火防蔓延智能窒息控火系统具有体积更小、更加隐蔽、美观大方及便于装修的优点，于较小空间常开方式，不影响原来门窗的功能。

具体实施方式
为了详细说明本申请的技术内容、构造特征，以下结合实施方式并配合附图作进一步说明。
请参阅图1至图4，本申请第一实施例的挡烟闭火防蔓延智能窒息控火系统100包含卷帘组件10及用于根据房间200内的温度变化而选择性地释放卷帘组件10的自动释放装置。卷帘组件11分别安装于房间200中与门口210相对应的墙体230及与窗口220相对应的墙体240上，卷帘组件11包含防火幕帘11、用于将防火幕帘11卷绕成卷状的卷绕轴12及装配于防火幕帘11之展开端11a上的配重块13，卷绕轴12可转动地装配于墙体230(240)上。配重块13在自动释放装置释放卷帘组件11下带动防火幕帘11自由展开及落下，以关闭门口210和窗口220，关闭门口210的状态见图3所示。具体地，在本实施例中，自动释放装置包含温控释放装置，举例而言，温控释放装置为温控熔断丝20，温控熔断丝20将配重块13和防火幕帘11捆绑固定，较优的是，捆绑固定位置处位于配重块13和防火幕帘11两者的中间位置处，这样设计使得温控熔断丝20对卷帘组件11束缚固定更简单，并确保密封可靠性；故在房间200内的环境温度变化达到阈值(即熔点)时，温控熔断丝20自动熔断的，实现对卷帘组件10自动释放目的，这使得第一实施例的挡烟闭火防蔓延智能窒息控火系统100的工作更可靠，避免因使用电子器件而存在失灵的缺陷。需要说明的是，根据实 际需要，温控熔断丝20对卷帘组件11束缚方式还可以有图6所示；在图6中，温控熔断丝20的一端与配重块13固定，温控熔断丝20的另一端与墙体230(240)固定；又或者，温控熔断丝20的一端与防火幕帘11的展开端11a固定，温控熔断丝20的另一端与墙体230(240)固定，均能达到对卷帘组件11束缚固定的连接。举例而言，窗口220所对应的温控熔断丝20的阈值(熔点)小于门口210所对应的温控熔断丝20的阈值，这样设计的目的是在房间200着火后，先关闭窗口220后再关闭门口210，以及时地阻隔火焰从窗口220向上蔓延，并利于着火房间200内的人员逃离；较优的是，窗口220所对应的温控熔断丝20的阈值选择为(70±10)度，而门口210所对应的温控熔断丝20的阈值选择为(170±10)度，但不限于此。更具体地，如下：
如图2至图4所示，为提高配重块13及防火幕帘11两者自由落下顺畅性及密封性，本申请的挡烟闭火防蔓延智能窒息控火系统100还包括用于对配重块13及防火幕帘11两者的运动提供导引的上下轨道30，上下轨道30装配于墙体230(240)上，较优的是，对于墙体230来说，上下轨道30是分别埋设于墙体230用于围出门口210的左右两内侧壁处，当然，根据实际需要而分别安装于墙体230的位于门口210左右两侧外的墙面处；对于墙体240来说，上下轨道30是分别埋设于墙体230用于围出窗口220的左右两内侧壁处，当然，根据实际需要而分别安装于墙体230的位于窗口220左右两侧外的墙面处；且上下轨道30位于卷绕轴12的正下方，配重块13及防火幕帘11两者的侧边嵌入上下轨道30并与该上下轨道30间隙配合，状态见图5所示，这样设计能提升落下后的防火幕帘11和配重块13两者各与上下轨道30之间的密封效果，提升门口210和窗口220各被关闭后的房间200的窒息效果。具体地，上下轨道30呈竖直布置并位于防火幕帘11和配重块13两者的侧边111、131外，且上下轨道30内部具有上下滑行避让空间31，以便于配重块13及防火幕帘11两者的侧边111、131嵌入上下轨道30内，但不以此为限；同时，配重块13为条形结构，配重块13与防火幕帘11之展开端11a的端部固定连接，减少卷状的防火幕帘11在卷绕轴12上预留的展开端11a自由长度，且配重块13主要由前方和后方 的横载面呈L形的条形结构构成，防火幕帘11之展开端11a的端部被夹持于前后方两条形结构之间，防火幕帘11的侧边111与后方的条形结构的侧边相平齐，且两者同时嵌入上下轨道30内。可理解的是，根据实际需要，可在自动释放装置未释放卷帘组件10前，使得配重块13的侧边131或防火幕帘11的侧边111嵌入上下轨道30内，故不以上述的举例为限。
如图2所示，为便于卷绕轴12与建筑物200之间安装，本申请的挡烟闭火防蔓延智能窒息控火系统100还包括与墙体230(240)装配连接的支座40，卷线轴12伸出防火幕帘11的端部12a可转动地装配于支座40上，较优的是，对于墙体230来说，支座40是安装于墙体230位于门口210上方的墙面处，对于墙体240来说，支座40是安装于墙体240位于窗口220上方的墙面处，但不限于此。为提高卷绕轴12工作可靠性，支座40分别布置于卷绕轴12左右两侧的端部处，以使得卷绕轴12左右两侧中的端部12a与同侧中的支座40装配连接，但不以此为限。
请参阅图7及图8，展示了本申请第二实施例的挡烟闭火防蔓延智能窒息控火系统100`，其与第一实施例的挡烟闭火防蔓延智能窒息控火系统100的区别在于自动释放装置，其它与第一实施例的相同。下面对本实施例的挡烟闭火防蔓延智能窒息控火系统100`中的自动释放装置30进行详细说明。
在本实施例中，自动释放装置30包含用于感测房间200内环境变化的传感器31、用于接受传感器31所反馈信息的控制器32及用于对卷帘组件10锁定的执行机构33。控制器32分别与传感器31和执行机构33电性连接，控制器32根据传感器31的反馈信息去控制执行机构31做释放卷帘组件10的运动。具体地，在控制器32将传感器31反馈信息与控制器32设定的参数进行对比分析过程中，当传感器31反馈信息达到设定的参数时，此时由控制器32控制执行机构33做释放卷帘组件10的运动，以确保卷帘组件10释放的精确性。举例而言，传感器31包含温度传感器，此时由温度传感器将采用到的温度信息反馈给控制器32；在控制器32将温度传感器所反馈的温度值与控制器32设定的温度值进行对比分析过程中，当温度传感器所反馈的温度值达到设定的温度值时，此时 由控制器32控制执行机构33做释放卷帘组件10的运动。举例而言，窗口220所对应的传感器31的预设值【例如：针对窗梁设定的温度值为(70±10)度】小于门口210所对应的传感器31的预设值【例如：针对门口上梁设定的温度值为(170±10)度】，这样设计的目的是在房间200着火后，先关闭窗口220后再关闭门口210，以及时地阻隔火焰从窗口220向上蔓延，并利于着火房间200内的人员逃离。可理解的是，根据实际需要，传感器31可包含烟雾传感器，此时由烟雾传感器将采用到的烟雾信息反馈给控制器32；在控制器32将烟雾传感器所反馈的烟雾值与控制器32设定的烟雾值进行对比分析过程中，当温度传感器所反馈的温度达到设定的温度值时，此时由控制器32控制执行机构33做释放卷帘组件10的运动，故不以上述的举例为限。需要说明的是，传感器31是安装于房间200内，例如在房间200与门口210相对应的墙体230、与窗口220相对应的墙体240或房间200的墙顶等位置处；而控制器32可安装于房间200内或房间200外，但这都是本领域根据实际需要而灵活选择的，故不以此为限；另，传感器31可分别安装于墙体230和墙体240上，也可以只安装于墙体230或墙体240处。
如图7所示，执行机构33主要由电机331及装配于电机331之输出轴上的承托杆332构成，电机331装配于上下轨道30之上端的外面，而承托杆332位于上下轨道30的上下滑行避让空间31内，并位于配重块13的正下方，故在电机331驱使承托杆332旋转至水平位置时，使得承托杆332承托配重块13，而在电机331驱使承托杆332旋转至竖直位置时，则脱离对配重块13的承托阻挡，因而达到自动释放卷帘组件10的目的。需要说明的是，执行机构33可安装于上下轨道30上、墙体230或墙体240处。
与现有技术相比，由于卷帘组件10分别安装于房间200中与门口210相对应的墙体230及与窗口220相对应的墙体240上，且卷帘组件10包含防火幕帘11、用于将防火幕帘11卷绕成卷状的卷绕轴12及装配于防火幕帘11之展开端11a上的配重块13，卷绕轴12可转动地装配于墙体230(240)上，并结合自动释放装置，由自动释放装置根据房间200内环境变化(例如温度变化和/或烟雾 变化)而选择性地释放卷帘组件10，故卷帘组件10的释放更精准可靠；同时，在自动释放装置释放卷帘组件10时，配重块13则直接带动防火幕帘11自由展开及落下，以同时关闭着火房间200的门口210和窗口220，从而使着火的小空间的房间200处于封闭状态，除起到挡烟、闭火和防蔓延作用外，更具有窒息灭火作用，这是由于着火的房间200被封闭，外界氧气没法从门口210和窗口220往房间200内补充，且着火的房间200所产生的二氧化碳无法排出而于房间200内累积，二氧化碳本身具有灭火作用。另，正由于防火幕帘11的自由展开及落下是由配重块13的重力所带动，故简化用于驱使防火幕帘11展开及落下的结构，并确保防火幕帘11展开及落下的可靠性。此外，本申请的挡烟闭火防蔓延智能窒息控火系统100具有体积更小、更加隐蔽、美观大方及便于装修的优点，于较小空间常开方式，不影响原来门窗的功能。
值得注意者，防火幕帘11在卷绕轴12上卷绕成卷状是在安装于墙体230前已卷好的，是由操作人员手动或借助机械设备所实现，并由自动释放装置对卷好后的卷帘组件10进行束缚固定。此外，防火幕帘11、卷绕轴12、上下轨道30及支座40各由防火材料制成，例如但不限于此的不锈钢材质，以使耐火温度高达1100度。
以上所揭露的仅为本申请的较佳实例而已，不能以此来限定本申请之权利范围，因此依本申请权利要求所作的等同变化，均属于本申请所涵盖的范围。
