近些年，随着科技的飞跃式发展，各大基站也得到了大力推广，比如，5G基站等。其中，在基站的基础运行设备中，储能设备在用于储能和供能方面有着重要的意义，然而，储能设备在安全方面也有着较高的使用要求。
发明人发现，对于一般的储能设备而言，储能设备内部的电池上通常设置有泄压阀，泄压阀被配置为在电池内部的温度或压力达到阈值时释放电池的内部压力，以减少电池在使用过程中因热失控而出现爆炸的风险。但是，在储能设备的应用过程中，由于天气原因、电池老化、过度充电等异常原因常常会造成储能设备的电池出现热失控的现象，而电池排放的热失控气体极容易引发起火爆炸等安全隐患。为了降低储能设备发生起火爆炸的风险，在现有技术中，通常在储能设备的柜体内设置有点燃装置，且每个点燃装置与一个电池对应设置，通过将点燃装置与电池的泄压阀连通，使得点燃装置能够将泄压阀释放的烟气进行点燃后燃烧处理，以降低泄压阀释放的烟气在柜体内堆积后出现起火爆炸等风险。然而，这种结构的储能设置一方面由于柜体内的含氧量较低，从而极容易出现泄压阀释放的烟气燃烧处理不完善的现象，且烟气的燃烧空间有限，进而使得储能设备依旧存在烟气在柜体内堆积后引发的起火爆炸等风险，另一方面点燃装置在对泄压阀释放的烟气处理后依旧会存在有毒有害的气体，若气体直接排放至外部环境中，极容易对环境造成污染，不利于储能设备的推广和使用。
基于上述考虑，为了解决储能设备在使用过程中的使用安全性较低的问题，发明人经过深入研究，设计了一种储能设备，储能设备包括柜体、电池和集气仓。柜体具有第一壁部。电池容纳于柜体内。集气仓设置于第一壁部，且集气仓位于柜体的外侧，集气仓的内部形成有容纳空间。第一壁部上设置有与容纳空间连通的排气口，容纳空间用于容纳电池释放的排放物。
在这种结构的储能设备中，通过将集气仓设置于第一壁部背离柜体内部的一侧，且在第一壁部上设置有与集气仓的容纳空间连通的排气口，使得电池在热失控时释放的排放物能够通过排气口进入至集气仓的容纳空间内，以使集气仓能够收集并容纳电池在出现异常时释放的排放物，便于对电池释放的排放物进行集中处理，采用这种结构的储能设备一方面能够减少电池释放的排放物排放至外部环境的现象，有利于降低对环境的污染，另一方面能够便于后续对排放物进行集中处理，以减少排放物在储能设备的柜体内处理不完善的现象，且能够降低排放物在柜体内堆积而引发的起火或爆炸风险，从而有利于提升储能设备的使用安全性。
本申请实施例提供一种储能设备，其能够改善现有的储能设备在电池出现热失控现象时极容易发生爆燃或炸裂等风险，从而由此引发大面积起火爆炸等安全隐患，且极容易对外部环境造成污染，进而不利于推广和使用的问题，以下结合附图对储能设备的具体结构进行详细阐述。
根据本申请的一些实施例，请参照图1-图4，图1为本申请一些实施例提供的储能设备100的结构示意图，图2为本申请一些实施例提供的储能设备100的结构爆炸图，图3为本申请一些实施例提供的储能设备100的柜体10的结构示意图，图4为本申请一些实施例提供的储能设备100的集气仓30的结构示意图。本申请提供了一种储能设备100，储能设备100包括柜体10、电池20和集气仓30。柜体10具有第一壁部11。电池20容纳于柜体10内。集气仓30设置于第一壁部11，且集气仓30位于柜体10的外侧，集气仓30的内部形成有容纳空间31。其中，第一壁部11上设置有与容纳空间31连通的排气口111，容纳空间31用于容纳电池20释放的排放物。
其中，柜体10由多个侧壁围合而成，以在柜体10的内部形成用于装配电池20的装配空间，第一壁部11为柜体10的多个侧壁中的一个侧壁。
柜体10和容纳于柜体10内的电池20的形状均可以是多种，比如，长方体结构、三棱柱结构或圆柱体结构等。示例性的，在图2和图3中，柜体10和电池20均为长方体结构。
参见图1-图3，集气仓30设置于第一壁部11，且集气仓30位于柜体10的外侧，即集气仓30设置于第一壁部11背离柜体10内部的一侧，这种结构便于对集气仓30进行设计和装配，且能够根据实际需求设置不同大小的集气仓30，此外，便于将集气仓30内容纳的排放出导出进行统一处理。
可选地，集气仓30设置于第一壁部11上的结构可以是多种，比如，集气仓30可以是与第一壁部11为一体式结构，也可以是分体式结构。当集气仓30与第一壁部11为一体式结构时，集气仓30与第一壁部11可以采用铸造、冲压等工艺制成；当集气仓30与第一壁部11为分体式结构时，集气仓30可以采用焊接、粘接或螺栓螺接等方式连接于第一壁部11上。示例性的，在本申请实施例中，集气仓30通过螺栓螺接于第一壁部11上。
参见图2和图4，第一壁部11上设置有与容纳空间31连通的排气口111，即设置于第一壁部11上的排气口111能够连通集气仓30的容纳空间31和柜体10的内部，以使电池20在热失控时释放的排放物能够通过排气口111进入至集气仓30的容纳空间31内。
通过将集气仓30设置于第一壁部11背离柜体10内部的一侧，且在第一壁部11上设置有与集气仓30的容纳空间31连通的排气口111，使得电池20在热失控时释放的排放物能够通过排气口111进入至集气仓30的容纳空间31内，以使集气仓30能够收集并容纳电池20在出现异常时释放的排放物，便于对电池20释放的排放物进行集中处理，采用这种结构的储能设备100一方面能够减少电池20释放的排放物排放至外部环境的现象，有利于降低对环境的污染，另一方面能够便于后续对排放物进行集中处理，以减少排放物在储能设备100的柜体10内处理不完善的现象，且能够降低排放物在柜体10内堆积而引发的起火或爆炸风险，从而有利于提升储能设备100的使用安全性。
根据本申请的一些实施例，参见图2、图3和图4所示，集气仓30的一侧形成与容纳空间31连通的开口32，第一壁部11封闭开口32。
其中，集气仓30的一侧形成与容纳空间31连通的开口32，第一壁部11封闭开，即集气仓30设置为一侧开放的结构，且将集气仓30盖合于第一壁部11上。
示例性的，在第一壁部的厚度方向X上，集气仓30面向第一壁部11的一侧形成有翻边部33，翻边部33沿开口32的周向延伸并环绕开口32设置，翻边部33用于与第一壁部11相连，以实现集气仓30连接于第一壁部11上。
集气仓30的结构可以是多种，比如，长方体结构、三棱柱结构或六棱柱结构等。示例性的，在图4中，集气仓30为一侧形成开口32的长方体结构。
通过在集气仓30的一侧上设置开口32，且第一壁部11能够封闭开口32，以使集气仓30安装于第一壁部11上，从而能够实现第一壁部11上的排气口111与集气仓30的容纳空间31连接，这种结构简单，且便于制造和装配。
根据本申请的一些实施例，参照图2，并请进一步参照图5，图5为本申请一些实施例提供的储能设备100的第一密封件40的结构示意图。储能设备100还包括第一密封件40。第一密封件40设置于集气仓30与第一壁部11之间，且第一密封件40沿开口32的周向设置，第一密封件40用于密封集气仓30与第一壁部11。
其中，第一密封件40沿开口32的周向设置，即第一密封件40为沿开口32的周向延伸的环形结构。沿第一壁部的厚度方向X，第一密封件40设置于第一壁部11与集气仓30的翻边部33之间，以密封集气仓30与第一壁部11之间的间隙。
示例性的，开口32为长方形，对应的，第一密封件40为长方形环状结构。
第一密封件40的材质可以是多种，比如，橡胶、硅胶、塑料或泡棉等。示例性的，在本申请实施例中，第一密封件40的材质为泡棉，第一密封件40呈压缩状态设置于第一壁部11与集气仓30的翻边部33之间，且第一密封件40在压缩前和压缩后的压缩比为40％-60％，这种结构有利于提升第一密封件40对集气仓30和第一壁部11之间的间隙的密封效果。
通过在集气仓30与第一壁部11之间设置第一密封件40，且将第一密封件40设置为沿集气仓30的开口32的周向延伸的环形结构，使得第一密封件40能够密封集气仓30与第一壁部11之间的间隙，以减少容纳空间31内的排放物出现从集气仓30与第一壁部11之间的间隙处泄露的现象，从而有利于提升集气仓30对电池20的泄压机构21释放的排放物的收集效果。
根据本申请的一些实施例，参见图5所示，第一密封件40的宽度为D 1，满足，D 1≥5mm。
其中，第一密封件40的宽度D 1为环形结构的第一密封件40的内边缘与外边缘之间的间距。
通过将第一密封件40的宽度设置为大于或等于5mm，即将环形结构的第一密封件40的内边缘与外边缘之间的间距设置为大于或等于5mm，采用这种结构的第一密封件40能够便于集气仓30通过第一密封件40连接在第一壁部11上，比如，在第一密封件40上打孔进行螺栓连接等，以降低第一密封件40出现密封失效的风险。比如，由于需要在第一密封件40上打孔供连接集气仓30和第一壁部11的螺栓穿过，若第一密封件40的宽度小于5mm，则极容易造成第一密封件40在设置有螺栓的位置的宽度过小，从而极容易出现密封失效的现象。
根据本申请的一些实施例，请参见图2和图5所示，D 1≥8mm。
示例性的，第一密封件40的宽度D 1可以为8mm、8.5mm、9mm、10mm、11mm或15mm等。
当第一密封件40的宽度小于8mm时，第一密封件40的密封效果不佳，无法有效对集气仓30和第一壁部11之间的间隙进行封堵，从而通过进一步将第一密封件40的宽度设置为大于或等于8mm，采用这种结构的第一密封件40能够有效保证第一密封件40对集气仓30和第一壁部11的密封效果，以进一步提升集气仓30与第一壁部11之间的密封质量。
根据本申请的一些实施例，参见图2和图3所示，电池20具有泄压机构21，泄压机构21与排气口111相对设置，泄压机构21被配置为释放电池20单体的内部压力。排气口111用于连通容纳空间31和泄压机构21，容纳空间31用于容纳泄压机构21释放的排放物。
其中，泄压机构21与排气口111相对设置，即在第一壁部的厚度方向X上，泄压机构21面向第一壁部11设置，且排气口111覆盖泄压机构21的至少部分。
泄压机构21用于在电池20的内部压力或温度达到预定值时释放电池20内部的压力。示例性的，泄压机构21可以是诸如防爆阀、防爆片、气阀、泄压阀或安全阀等部件。
电池20上设置有用于释放电池20单体内部压力的泄压机构21，通过将泄压机构21与排气口111相对设置，使得泄压机构21释放的排放物能够通过排气口111直接排放至集气仓30的容纳空间31内，以减少电池20的泄压机构21释放的排放物在柜体10内堆积的现象，从而有利于降低排放物在柜体10内堆积而引发的起火或爆炸风险，以提升储能设备100的使用安全性。
根据本申请的一些实施例，参见图2、图3和图4所示，沿第一壁部的厚度方向X，泄压机构21在第一壁部11上的投影位于排气口111内。
其中，泄压机构21在第一壁部11上的投影位于排气口111内，即在第一壁部的厚度 方向X上，排气口111能够覆盖泄压机构21。
通过将泄压机构21在第一壁部的厚度方向X上的投影设置为落入排气口111内，采用这种结构的储能设备100能够有效保证泄压机构21释放的排放物直接通过排气口111进入至集气仓30的容纳空间31内，以减少泄压机构21在释放排放物时受到第一壁部11阻挡的现象。
根据本申请的一些实施例，参照图2，并请进一步参照图6，图6为本申请一些实施例提供的储能设备100的电池20与第二密封件50的连接示意图。电池20具有第一侧壁22，第一侧壁22与第一壁部11相对设置，泄压机构21设置于第一侧壁22上。
其中，第一侧壁22与第一壁部11相对设置，即电池20的第一侧壁22在第一壁部的厚度方向X上与第一壁部11面向设置。
电池20在第一壁部的厚度方向X上与第一壁部11面向设置的第一侧壁22，通过将泄压机构21设置于第一侧壁22上能够便于将泄压机构21设置为与第一壁部11上的排气口111相对设置的结构，这种结构简单，且便于装配。
在一些实施例中，请继续参见图2和图6所示，储能设备100还可以包括第二密封件50。第二密封件50设置于第一侧壁22与第一壁部11之间，且第二密封件50沿排气口111的周向设置，第二密封件50用于密封第一侧壁22与第一壁部11。
其中，第二密封件50沿排气口111的周向设置，即第二密封件50为沿排气口111的周向延伸的环形结构。
示例性的，排气口111为圆形，对应的，第二密封件50为圆形环状结构。
第二密封件50的材质可以是多种，比如，橡胶、硅胶、塑料或泡棉等。示例性的，在本申请实施例中，第二密封件50的材质为泡棉，第二密封件50呈压缩状态设置于第一壁部11与第一侧壁22之间，且第二密封件50在压缩前和压缩后的压缩比为40％-60％，这种结构有利于提升第二密封件50对第一侧壁22和第一壁部11之间的间隙的密封效果。
通过在电池20安装有泄压机构21的第一侧壁22与第一壁部11之间设置第二密封件50，且第二密封件50为沿排气口111的周向延伸的环形结构，使得第二密封件50能够密封第一壁部11和电池20的第一侧壁22之间的间隙，以缓解泄压机构21释放的排放物从第一壁部11和第一侧壁22之间的间隙泄漏至柜体10内的现象，从而能够减少排放物在柜体10内堆积而引发的起火爆炸现象，以提升储能设备100的使用安全性。
根据本申请的一些实施例，参见图2和图6所示，第二密封件50环绕于泄压机构21的外侧。也就是说，第二密封件50环绕泄压机构21设置，使得泄压机构21位于第二密封件50的内侧。
通过将第二密封件50环绕设置于泄压机构21的外侧，从而使得第二密封件50能够将泄压机构21与柜体10内的空间进行有效分隔，以降低泄压机构21释放的排放物进入至柜体10内的风险。

其中，第二密封件50的宽度D 2为环形结构的第二密封件50的内边缘与外边缘之间的间距。
通过将第二密封件50的宽度设置为大于或等于5mm，即环形结构的第二密封件50的内边缘与外边缘之间的间距为大于或等于5mm，采用这种结构的第二密封件50能够降低第二密封件50出现密封失效的风险。比如，若需要在第二密封件50上打孔供连接第一壁部11和 第一侧壁22的螺栓穿过，当第二密封件50的宽度小于5mm，则极容易造成第二密封件50在设置有螺栓的位置的宽度过小，从而极容易出现密封失效的现象。
根据本申请的一些实施例，请参见图2、图6和图7所示，D 2≥8mm。
示例性的，第二密封件50的宽度D 2可以为8mm、8.5mm、9mm、10mm、11mm或15mm等。
当第二密封件50的宽度小于8mm时，第二密封件50的密封效果不佳，无法有效对第一壁部11和第一侧壁22之间的间隙进行封堵，从而通过进一步将第二密封件50的宽度设置为大于或等于8mm，采用这种结构的第二密封件50能够有效保证第二密封件50对第一壁部11和电池20的第一侧壁22的密封效果，以进一步提升第一壁部11与电池20的第一侧壁22之间的密封质量。
