技术领域
本申请涉及电池技术领域，例如涉及一种深海电池装置。
背景技术
相关技术中，深潜器、深潜运载器、深海救生装备等深海设备通常需要在几百米、乃至数千米的深海压力环境下工作。随着深海设备下潜的深度的增加，深海设备的电池装置承受的压力也相应增加。
电池装置通常采用压力补偿组件承受海水的压力，起到调节电池装置内外压力的作用。相关技术中的压力补偿组件通常通过螺丝安装在电池装置上，而且压力补偿组件的皮囊采用平板式结构。此设计存在以下缺陷：在承压形变的过程中，皮囊的固定端变形量大，固定端产生拉扯容易使皮囊发生破裂，导致皮囊的使用寿命短，而且皮囊破裂导致压力补偿组件失去平衡压力的作用，电池装置会因海水的压力而无法正常工作甚至损坏。

本申请的实施例的深海电池装置应用于深海作业设备，为深海作业设备提供动力。
参照图1至图3所示，深海电池装置包括外壳1、皮囊2和防护盖3，外壳1上设有减压口11，皮囊2密封减压口11，皮囊2包括主体21、缓冲部22和连接部23，缓冲部22设置在主体21与连接部23之间，连接部23夹设于防护盖3与外壳1之间，缓冲部22至少包括一个环形设置在主体21周部的缓冲凸包221，缓冲凸包221朝向外壳1的内部凸出，缓冲凸包221远离外壳1内部的一侧形成凹槽222，凹槽222的槽口朝向防护盖3，防护盖3上开设有通孔31，通孔31与主体21的位置对应，主体21低于外壳1的开设有减压口11的外侧面。在一实施例中，外壳1内填充有惰性油，皮囊2的主体21与防护盖3贴合，当海底的压力穿过通孔31作用于电池的外壳1时，会先作用在皮囊2的主体21上，驱使主体21朝向外壳1的内部方向变 形移动，然后再作用在缓冲部22上，缓冲凸包221与主体21的连接处的变形量大于缓冲凸包221与连接部23的连接处的变形量，能够大幅减小连接部23的变形量，从而避免皮囊2的连接部23因拉扯而容易发生损坏，从而保护皮囊2以提高皮囊2的使用寿命，此时皮囊2被压缩的体积大于惰性油被压缩的体积，皮囊2能够起到平衡压力的作用；而缓冲凸包221朝向外壳1的内部凸出设置，能够减少皮囊2的占用空间，从而设置更多的电池组，提高深海电池装置的能量密度；同时，由于连接部23的变形量小，在满足皮囊2平衡压力的需求的同时，皮囊2的壁厚能够采用更薄的设计，以节省材料，降低制造成本。
在一实施例中，皮囊2的壁厚为2mm。
在一实施例中，如图4所示，沿水平方向，防护盖3与连接部23的抵接面的长度大于外壳1与连接部23的抵接面的长度。此设计能够使缓冲凸包221与外壳1之间具有一定的距离a，以形成变形空间。当皮囊2发生变形时，缓冲凸包221与连接部23的连接处具有较大的弯曲角度，进一步避免皮囊2的连接部23因拉扯而破裂。
在一实施例中，主体21上朝内部凸出设置有导向凸包211，导向凸包211远离外壳1内部的一侧形成第一导向槽212，第一导向槽212的槽口朝向防护盖3，防护盖3上朝向皮囊2凸出设置有凸起33，凸起33插设在导向凸包211内，凸起33远离皮囊2内部的一侧形成第二导向槽34，第二导向槽34的槽口朝向背离皮囊2的一侧，通孔31设置在凸起33上。第二导向槽34能够将海水的压力指引至第一导向槽212内，引导海水的压力先作用在皮囊2在主体21上，以使皮囊2的变形由主体21朝向缓冲部22和连接部23依次扩散。
在一实施例中，皮囊2采用橡胶制成。在一实施例中，皮囊2采用丁腈橡胶NBR制成。在其他实施例中，皮囊2采用其他高分子复合橡胶制成，在此不对皮囊2的材质做出限定。
在一实施例中，防护盖3为金属盖，金属盖的密度为0.2g/cm 3～8.0g/cm 3。在一实施例中，金属盖的密度为2.5g/cm 3、2.6g/cm 3、2.7g/cm 3、2.8g/cm 3、3g/cm 3等。在一实施例中，防护盖3为铝合金，铝合金的密度为2.63g/cm 3～2.85g/cm 3，且具有较高的强度和良好的耐蚀性，能够承受海水的压力和抵抗海水的腐蚀，从而提高深海电池装置的结构强度。
在本实施例中，参照图4所示，外壳1包括环形设置在减压口11周部的台阶槽13，皮囊2和防护盖3通过紧固件6固定在台阶槽13的槽底，多个紧固件6沿台 阶槽13的槽底的周部间隔设置。在一实施例中，紧固件6为螺丝，皮囊2的连接部23沿周向间隔设置有多个第一开孔，防护盖3设置有多个与第一开孔对应的第二开孔，外壳1上设有螺纹孔，螺丝通过第一开孔和第二开孔与螺纹孔配合，以使防护盖3和皮囊2同时固定于台阶槽13内上，皮囊2和防护盖3低于外壳1的开设有减压口11的外侧面，能够进一步减少深海电池装置的体积，而且多个紧固件6沿台阶槽13的槽底的周部间隔设置能够保证皮囊2和防护盖3的周部受力均匀地固定在外壳1上。
在一实施例中，参照图4所示，防护盖3和皮囊2分别通过面密封安装在外壳1上。在一实施例中，连接部23沿周向凸出设置有第一密封件4，第一密封件4为皮囊2的连接部23朝外壳1凸出设置形成的第一密封筋条，外壳1包括与皮囊2连接的连接面，连接面上设置有密封槽12，第一密封筋条插入至密封槽12内。外壳1和皮囊2通过第一密封件4和密封槽12的配合形成第一密封结构，避免海水从皮囊2和外壳1的连接处流入皮囊2内部。
在一实施例中，防护盖3上设置有凸筋32，凸筋32与连接部23靠近防护盖3的一侧抵接并与第一密封件4的位置对应。凸筋32能够使皮囊2在与凸筋32抵接处朝向外壳1方向产生形变，产生的形变对第一密封件4施加一定的作用力，以使第一密封件4更加紧密地镶嵌在密封槽12内，加强第一密封件4的密封效果。
在一实施例中，第一密封件4的宽度为1.2～2mm,凸出高度为1～3mm，密封槽12与第一密封件4的尺寸相匹配。此设计能够在保证第一密封件4的密封效果的同时，将尺寸设计得更小以节省材料。
在一实施例中，外壳1的连接面上至少设置有两个第二密封件5，外壳1的连接面朝皮囊2凸出设置形成第二密封筋条，第二密封筋条为第二密封件5，两个第二密封件5分别设置在密封槽12宽度方向的两侧，第二密封件5与连接部23靠近外壳1的一侧抵接。在一实施例中，通过在密封槽12宽度方向的两侧分别设置第二密封件5与皮囊2的连接部23抵接形成第二密封结构，进一步加强皮囊2与外壳1的连接面的密封效果，保证深海电池装置平衡海水压力的能力。
在一实施例中，第二密封件5的宽度为0.8-1.1mm，凸出高度为0.5-0.9mm，第二密封件5的宽度和凸出高度分别小于第一密封件4的宽度和凸出高度，此设计更有利于密封的效果；而且皮囊2和防护盖3安装在外壳1时，皮囊2的压缩量控制在25～30％之间，保证皮囊2与外壳1的第二密封件5抵接后具有良好的密封效果，且不会对皮囊2造成损坏。
