Description

说明书 一种温控隔离装置及应用温控隔离装置的设备
[1] 技术领域
[2] 本实用新型涉及自动机械技术领域， 尤其涉及一种温控隔离装置及应用温控隔 离装置的设备。
[3] 实用新型背景
[4] 许多场合对防火安全都有非常高的要求， 当一个地方着火吋需要控制火焰不能 扩散到其它地方， 通常釆用自动化的防火门隔断火焰的扩散。 而对于防火安全 有很高的要求的通讯设备来说， 如通讯设备内部着火的情况下， 火焰当然也不 能扩散到通讯设备外部， 防止对通讯设备外的其他设备有不利的影响。
[5] 在通讯设备内部燃烧的过程中， 火焰最有可能扩散出来的地方是通讯设备的出 风口。 现有技术有一种技术方案， 利用低熔点的材料将一个可以堵住出风口的 档板固定， 例如利用尼龙绳将档板拴住， 正常情况下保持出风口通风。 当设备 内部的温度太高吋， 低熔点的材料熔化， 使档板落下， 档住出风口。 由于现有 技术方案中使用的是低熔点的材料， 如尼龙等固定出风口的档板。 当设备长吋 间使用后， 这些材料可能会由于变质、 老化、 损毁、 还有可能由于震动等原因 导致档板异常脱落， 使得设备内部没有出现高温吋， 出现误动作， 将出风口档 住， 影响设备的正常工作。
[6] 实用新型内容
[7] 本实用新型的实施例提供了一种温控隔离装置及应用温控隔离装置的设备， 可 防止设备内部燃烧吋的火焰扩散到设备外部， 且可长吋间使用， 稳定可靠， 不 会出现误动作。
[8] 本实用新型实施例提供了一种温控隔离装置的实施例， 其设于设备通风口处， 当设备内温度达到临界点吋阻断通风口隔离设备内外空间， 且包括固定于设备 机架上的档板与卡位机构， 正常工作吋档板开启， 卡位机构卡住档板； 所述的 卡位机构包括双金属片； 双金属片随设备内温度变化产生变形驱动卡位机构动 作， 当设备内温度达到临界点吋双金属片驱动卡位机构脱开档板， 档板复位档 住设备通风口， 隔离设备内外空间。
本实用新型还一种具有温控隔离装置的设备的实施例， 具体是在设备的通风口 处设有所述的温控隔离装置， 当设备内温度达到临界点吋阻断通风口隔离设备 内外空间。
由上述本实用新型实施例提供的技术方案可以看出， 本实用新型所述的一种温 控隔离装置的实施例设于设备通风口处， 当设备内温度达到临界点吋， 阻断通 风口隔离设备内外空间， 可防止设备内部燃烧吋的火焰扩散到设备外部， 由于 卡位机构全部为金属部件， 由金属部件来支撑档板， 可以保证不会因为材料变 质、 老化等原因造成误动作。 即本实用新型提供的实施例具有可长吋间使用， 稳定可靠， 且不会出现误动作等优点。

图 3为本实用新型的一种温控隔离装置的实施例结构示意图三；
图 4为本实用新型的应用温控隔离装置的设备的实施例结构示意图。
实施本实用新型的方式
本实用新型实施例提供的温控隔离装置中， 具体釆用了双金属片作为控制档板 开启或关闭的卡位机构， 从而可以保证温控隔离的准确动作。
本实用新型实施例作为设备的温控隔离装置， 具体可以安装于设备中包括的设 备机架上， 即以设备机架作为固定安装所述温控隔离装置的固定支架， 所述的 温控隔离装置中： 档板在开启状态吋， 设备通风口开启； 档板在关闭状态吋， 设备通风口关闭。
本实用新型实施例所述的一种温控隔离装置如图 1所示， 所述的温控隔离装置 用螺钉或铆接等任意方式固定在设备通风口 4处， 当设备内温度达到临界点吋阻 断通风口 4隔离设备内外空间， 结构上具体包括使用活页或铰链方式固定于设备 机架 7上的档板 1与使用螺钉或铆接等方式固定于设备机架 7的卡位机构， 设备内 温度低于临界点吋， 档板 1位于开启位置， 具体是由卡位机构卡住档板 1 (如通 过互相搭接方式卡住） ； 这吋设备通风口 4为开启状态， 本实用新型实施例的卡 位机构中包括可随温度变化产生变形的双金属片 3; 双金属片 3随设备内温度变 化产生变形， 以驱动卡位机构动作， 当设备内温度达到临界点吋； 卡位机构脱 开档板 1 (如档板 1与卡位机构不再相互搭接， 而相互错开） ， 以复位至关闭状 态， 从而档住设备通风口 4， 隔离设备内外空间。
[20] 为便于对本实用新型实施例的理解， 下面将结合附图对其具体实现结构进行详 细说明。
[21] 请参阅图 1和图 2， 本实用新型实施例所述的温控隔离装置的档板 1的上端使用 活页或铰链固定于通风口 4上方的设备机架 7上， 档板 1的下端翻起后卡于卡位机 构中， 档板 1位于开启位置； 当卡位机构中的卡板 2的凸块滑入档板 1的开口 12吋 ， 卡板 2与档板 1之间不再搭接， 故档板 1将依靠自重复位至关闭位置 （即处于关 闭状态） ， 档住设备通风口 4， 隔离设备内外空间。 这种结构适用于设备通风口 4的位置可满足档板 1靠自重复位的情况下， 如设备通风口 4位于设备的侧面或底 面等。
[22] 当然， 如果设备通风口 4位于设备的顶面， 设备通风口 4无法靠自重复位的情况 下， 本实用新型实施例所述的温控隔离装置， 还包括控制档板 1复位的复位机构 ， 复位机构与档板 1连接， 如接触连接等， 当卡位机构脱开档板 1吋， 档板 1靠复 位机构驱动复位至关闭位置。 例如， 复位机构可以为一拉伸弹簧， 一端固定在 档板 1上， 另外一端固定在机架上， 类似于房门上的拉伸弹簧的应用。 复位机构 还可以为一扭转弹簧安装于档板 1与设备机架 7的铰接处。
[23] 如本实用新型的实施例的图 2与图 3所示， 所述的卡位机构具体可以包括至少一 个双金属片 3及卡板 2; 双金属片 3可通过螺钉直接固定于机架 7上， 卡板 2可在设 备机架 7上移动 （如卡板 2可通过螺钉直接安装 （可活动） 于机架 7上而螺钉孔为 长条形孔） ， 设备内温度低于临界点吋卡板 2卡住档板 1 (如通过互相搭接方式 卡住等） ， 档板 1位于开启位置； 双金属片 3固定于设备机架 7上， 双金属片 3随 设备内温度变化产生变形， 由于双金属片 3靠近卡板 2， 卡板 2在金属片 3的变形 力的推动下， 在设备机架 7上移动， 当设备内温度达到临界点吋双金属片 3驱动 卡板 2至极限位置并脱开档板 1， 此吋， 档板 1由于重力或所述复位机构进行复位 至关闭位置， 档住设备通风口 4， 隔离设备内外空间。 本例中还包括一连接板 8 ， 连接板 8固定 （可通过螺钉直接固定） 于设备机架 7上， 双金属片 3固定 （可通 过螺钉直接固定） 于连接板 8上， 连接板 8上开有滑槽 9， 卡板 2上设有滑块 10， 滑块 10在滑槽 9中移动便可以实现了卡板 2相对设备机架 7的移动， 进而控制档板 1的开启或关闭。
[24] 所述的卡板 2与档板 1之间的具体实现结构可以为：
[25] 在卡板 2上设有至少一个凸块 11， 所述凸块 11可以突起设置于卡板 2边缘处， 档 板 1上的对应位置开设有开口 12， 设备内温度低于临界点吋， 凸块 11与开口 12错 开设置， 使得卡板 2档住档板 1 ; 档板 1位于开启位置； 设备内温度达到临界点吋 ， 双金属片 3随温度变化变形， 推动和它靠近的卡板 2在机架 7上移动并相对档板 1移动， 这样， 卡板 2上的凸块 11也将随着卡板 2移动至与开口 12相对的位置， 此 吋档板 1失去与卡板 2相互搭接的支撑， 将在重力或复位机构的作用下， 复位至 关闭位置， 档住设备通风口 4， 隔离设备内外空间。
[26] 当然， 也可在档板 1上设有至少一个凸块， 所述凸块可以突起设置于档板 1的边 缘处， 并在卡板 2上的对应位置设有开口。 其实现方式与前面描述相同， 这里不 再赞述。
[27] 为了保证在正常的条件下不会因为震动等原因有误动作， 本实用新型实施例所 述的温控隔离装置还包括限制卡板 2自由移动的安全机构， 安全机构向卡板 2施 加与双金属片 3随温度变形所移动方向相反的弹性力， 限制卡板 2自由移动。 本 实施例的安全机构包括安全滑块 5与安全复位弹簧 6， 安全滑块 5与上述的滑块 10 可以为一体的， 如图 3所示， 安全滑块 5与滑块 10为同一部件 (当然, 两者也可 以为各自独立设置， 图中未示出） ， 安全滑块 5用螺钉或铆钉固定于卡板 2上， 安全复位弹簧 6—端与安全滑块 5连接， 另一端与设备机架 7连接。 安全复位弹簧 6向卡板 2施加与双金属片 3随温度变形所移动方向相反的弹性力， 保证在正常的 条件下不会因为震动等原因有误动作。
[28] 本实用新型实施例所述的温控隔离装置的上述实施方式可进行简化， 所述的卡 位机构可以只包括至少一个双金属片 3， 双金属片 3固定于 （可通过螺钉直接固 定） 机架 7上， 设备内温度低于临界点吋， 双金属片 3的侧面直接支撑档板 1 ; 档 板 1位于开启位置； 双金属片 3随设备内温度变化产生变形弯曲， 导致支撑档板 1 的部分减少， 当设备内温度达到临界点吋， 双金属片 3弯曲到最大位置和档板 1 完全分开， 即档板 1完全失去双金属片 3对其的支撑， 并将在重力或复位机构的 作用下， 复位至关闭位置， 档住设备通风口 4， 隔离设备内外空间。
[29] 本实用新型实施例所述的温控隔离装置在正常情况下， 档板 1有卡位机构支撑 ， 处于顶部位置， 设备的通风口 4没有被封堵上， 设备正常通风散热。 本实用新 型实施例所述的温控隔离装置利用对温度敏感、 并且会随着温度升高而变形的 双金属片 3的变形力作为动力， 进而驱动档板 1动作， 以档住设备通风口 4， 让火 焰只能在设备内部燃烧， 不会燃烧到设备外部。 由于卡位机构全部为金属部件 ， 由金属部件来支撑档板 1， 可以保证不会因为材料变质、 老化等原因造成误动 作。 对于设备通风口 4较宽的情况， 可以使用多个双金属片 3， 保证在任何位置 发生异常， 都可以有效的封闭设备通风口 4。
[30] 如本实用新型的实施例的图 4所示， 本实用新型的实施例提供的一种具有温控 隔离装置的设备， 具体是在设备的通风口处设有上述的温控隔离装置， 例如， 可以安装于设备中包括的设备机架上， 当设备内温度达到临界点吋， 温控隔离 装置处于关闭状态， 以阻断通风口隔离设备内外空间。
[31] 以上所述， 仅为本实用新型较佳的具体实施方式， 但本实用新型的保护范围并 不局限于此， 任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内 ， 可轻易想到的变化或替换， 都应涵盖在本实用新型的保护范围之内。 因此， 本实用新型的保护范围应该以权利要求的保护范围为准。
