1、电池双极板体在安装后，保护外壳可以对电池双极板体进行防护，这样可以避免外力对电池双极板体进行直接挤压破坏；当保护外壳受到外力作用时，安装盒可以与缓冲弹簧之间相互作用，这就使得缓冲弹簧产生弹力对安装盒进行缓冲，这样可以避免电池双极板体受到外力作用后损坏的问题，延长了电池双极板体的使用寿命；1.

2、当导向块导入相应的安装盒时，导向块会与相应的楔形定位块接触且对其施加压力，这就使得楔形定位块向外滑动，此时回复弹簧被压缩积蓄弹性势能，当导向块活动到楔形定位块底部后，回复弹簧释放势能，这就使得楔形定位块恢复到初始位置且对导向块进行限制，从而使得导向块稳定安装在安装盒内，进而避免电池双极板体位置偏移，有利于增加安装的简便性；2. When the guide block is introduced into the corresponding installation box, the guide block will contact the corresponding wedge-shaped positioning block and exert pressure on it, which makes the wedge-shaped positioning block slide outward. At this time, the return spring is compressed to accumulate elastic potential energy. When the guide block moves to the bottom of the wedge-shaped positioning block, the return spring releases the potential energy, which makes the wedge-shaped positioning block return to its initial position and restricts the guide block, so that the guide block is stably installed in the installation box, thereby avoiding the position deviation of the battery bipolar plate body, which is conducive to increasing the simplicity of installation;

下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
实施例1：Embodiment 1:
参照图1-5，一种液流电池安全保护装置，包括保护外壳1，保护外壳1内侧的两端均滑动安装有安装盒2，两个安装盒2的外侧均固定安装有缓冲弹簧3，缓冲弹簧3远离相应的安装盒2的一端与保护外壳1的内壁固定连接，两个安装盒2内侧的上下两端均滑动安装有两个导向块22，导向块22的外侧均固定安装有滑块21，滑块21的外端均与同一个电池双极板体4固定连接；安装盒2的侧壁上开设有与滑块21相匹配的滑槽23，滑块21可沿着相应的滑槽23滑动。通过将导向块22导入相应的安装盒2内，同时滑块21与相应的滑槽23配合且进行滑动，这就实现了对电池双极板体4的安装，同样的，通过将导向块22直接从安装盒2内滑出也就实现对电池双极板体4的拆卸，从而可以实现对电池双极板体4的快速安装和拆卸；Referring to Figures 1-5, a flow battery safety protection device includes a protective shell 1, mounting boxes 2 are slidably mounted at both ends of the inner side of the protective shell 1, buffer springs 3 are fixedly mounted on the outer sides of the two mounting boxes 2, and the ends of the buffer springs 3 away from the corresponding mounting boxes 2 are fixedly connected to the inner wall of the protective shell 1, and two guide blocks 22 are slidably mounted at the upper and lower ends of the inner sides of the two mounting boxes 2, and sliders 21 are fixedly mounted on the outer sides of the guide blocks 22, and the outer ends of the sliders 21 are fixedly connected to the same battery bipolar plate 4; a slide groove 23 matching the slider 21 is provided on the side wall of the mounting box 2, and the slider 21 can slide along the corresponding slide groove 23. By introducing the guide block 22 into the corresponding mounting box 2, and the slider 21 cooperates with the corresponding slide groove 23 and slides, the battery bipolar plate 4 is installed, and similarly, by sliding the guide block 22 directly out of the mounting box 2, the battery bipolar plate 4 is disassembled, thereby realizing the rapid installation and disassembly of the battery bipolar plate 4;
电池双极板体4在安装后，保护外壳1可以对电池双极板体4进行防护，这样可以避免外力对电池双极板体4进行直接挤压破坏；当保护外壳1受到外力作用时，安装盒2可以与缓冲弹簧3之间相互作用，这就使得缓冲弹簧3产生弹力对安装盒2进行缓冲，这样可以避免电池双极板体4受到外力作用后损坏的问题，延长了电池双极板体4的使用寿命；After the battery bipolar plate 4 is installed, the protective shell 1 can protect the battery bipolar plate 4, so that the external force can prevent the battery bipolar plate 4 from being directly squeezed and damaged; when the protective shell 1 is subjected to an external force, the installation box 2 can interact with the buffer spring 3, so that the buffer spring 3 generates elastic force to buffer the installation box 2, so that the battery bipolar plate 4 can be prevented from being damaged after being subjected to an external force, thereby extending the service life of the battery bipolar plate 4;
保护外壳1的上下两端均安装有定位件5，定位件5包括滑杆51，滑杆51贯穿保护外壳1的内壁、且可与保护外壳1相互滑动，滑杆51的一端固定安装有楔形定位块52，楔形定位块52滑动安装在安装盒2的内侧、且可与相应的导向块22接触，滑杆51的另一端固定安装有拉块53，拉块53位于保护外壳1的外侧；滑杆51上套设有回复弹簧54，回复弹簧54位于楔形定位块52与保护外壳1的内壁之间；安装盒2上开设有与楔形定位块52相匹配的安装槽55，楔形定位块52可沿着安装槽55滑动；The upper and lower ends of the protective shell 1 are both provided with positioning members 5, the positioning members 5 include a slide bar 51, the slide bar 51 penetrates the inner wall of the protective shell 1 and can slide with the protective shell 1, one end of the slide bar 51 is fixedly provided with a wedge-shaped positioning block 52, the wedge-shaped positioning block 52 is slidably installed on the inner side of the installation box 2 and can contact with the corresponding guide block 22, the other end of the slide bar 51 is fixedly provided with a pull block 53, the pull block 53 is located on the outer side of the protective shell 1; a return spring 54 is sleeved on the slide bar 51, and the return spring 54 is located between the wedge-shaped positioning block 52 and the inner wall of the protective shell 1; a mounting groove 55 matching the wedge-shaped positioning block 52 is provided on the installation box 2, and the wedge-shaped positioning block 52 can slide along the mounting groove 55;
当导向块22导入相应的安装盒2时，导向块22会与相应的楔形定位块52接触且对其施加压力，这就使得楔形定位块52向外滑动，此时回复弹簧54被压缩积蓄弹性势能，当导向块22活动到楔形定位块52底部后，回复弹簧54释放势能，这就使得楔形定位块52恢复到初始位置且对导向块22进行限制，从而使得导向块22稳定安装在安装盒2内，进而避免电池双极板体4位置偏移，有利于增加安装的简便性；When the guide block 22 is introduced into the corresponding installation box 2, the guide block 22 will contact the corresponding wedge-shaped positioning block 52 and apply pressure to it, which makes the wedge-shaped positioning block 52 slide outward. At this time, the return spring 54 is compressed to accumulate elastic potential energy. When the guide block 22 moves to the bottom of the wedge-shaped positioning block 52, the return spring 54 releases the potential energy, which makes the wedge-shaped positioning block 52 return to the initial position and restricts the guide block 22, so that the guide block 22 is stably installed in the installation box 2, thereby avoiding the position deviation of the battery bipolar plate body 4, which is conducive to increasing the simplicity of installation;
电池双极板体4拆卸时，通过向外拉动拉块53使得滑杆51向外滑动，这就使得楔形定位块52向外移动且与导向块22脱离，此时导向块22不再受到楔形定位块52的限制，通过将导向块22直接从安装盒2内滑出也就实现对电池双极板体4的拆卸，操作十分简便；When the battery bipolar plate body 4 is disassembled, the pull block 53 is pulled outward to make the slide bar 51 slide outward, so that the wedge-shaped positioning block 52 moves outward and disengages from the guide block 22. At this time, the guide block 22 is no longer restricted by the wedge-shaped positioning block 52. The battery bipolar plate body 4 can be disassembled by directly sliding the guide block 22 out of the installation box 2, which is very simple to operate.
实施例2：Embodiment 2:

安装保护外壳1时，通过将保护外壳1外侧的卡块61直接与相应的卡座63配合，然后将固定螺栓64与卡块61上的螺孔65配合，这就使得卡块61能够稳定的安装在卡座63上；同样的，通过将固定螺栓64拆除可以实现保护外壳1的快速拆卸，这种结构大大提高了保护外壳1拆装的便捷性。When installing the protective shell 1, the block 61 on the outside of the protective shell 1 is directly matched with the corresponding socket 63, and then the fixing bolt 64 is matched with the screw hole 65 on the block 61, so that the block 61 can be stably installed on the socket 63; similarly, the protective shell 1 can be quickly disassembled by removing the fixing bolt 64. This structure greatly improves the convenience of disassembly and assembly of the protective shell 1.
