技术领域
本实用新型涉及换电站技术领域，具体涉及一种预制式换电站底板。
背景技术
换电站作为向电动汽车提供电池更换服务的能源补给站，随着电动汽车的推广普及，换电站也得到了普及应用。
现有的换电站都是采用集装箱作为整个站的外部结构，并且在集装箱内安装用于存储电池包的电池架、用于对电动汽车进行电池拆卸和安装的换电设备以及用于进行电池转运的电池转运设备等设备，换电站内所有的设备的安装都是通过在集装箱内的钢框架上打孔进行固定，或者采用焊接方式进行固定。
然而，这种固定方式受限于集装箱内的钢框架的位置，很容易导致设备安装位置不准确，安装精度较低；如，针对电池转运设备的安装，在安装设备之前还需要将集装箱底部的钢框架结构填平并找平，以满足安装设备的水平度要求；而且还需要增加额外的连接件进行固定。
其次，所有的设备还需要操作人员进入集装箱内对设备逐一进行安装固定，导致安装空间受限，不便于操作，极易出现部分设备或部件没有空间安装。
另外，为了满足换电站的容量需求，现有的换电站集装箱大都采用非标集装箱的一体式结构，导致生产完成的换电站整体规格非常庞大，建站成本很高，生产完成的换电站不便于运输，运输成本很高。而且，实际建站中， 还需要对建站场地进行地基处理，具体是地面找平与现浇处理，所需处理周期长，成本高。

在本方案中，通过在底板内设置减重区域，能够在不影响底板的承载性能的基础上，大幅度减轻混凝土底板的整体重量，便于运输，降低运输成本。另外，由于驱动机构的安装区域第二凹陷部已尽可能深地凹陷于底板的表面设置，因此，将第二凹陷部避让减重区域设置，能够避免第二凹陷部对应区域的强度受到影响而变形。
较佳地，所述电池转运设备还包括：至少具有两根纵梁的固定门架以及将所述轿厢连接于所述纵梁上的传动机构，所述驱动机构设置于任意的所述纵梁上，所述第二凹陷部内预埋有多个固定孔，用于对所述纵梁的底部进行固定。

较佳地，所述底板采用C30混凝土材料一体预制成型或由多模块拼接形成。
在本方案中，底板的形成过程灵活多样，可以根据实际生产需求定制，一体成型可以满足最高精度需求，节约换电站的建站周期；多模块拼接则便于运输，节约运输所需成本。
较佳地，所述第一凹陷部的深度值小于所述底板厚度的20％，所述第二凹陷部的深度值小于所述底板厚度的50％。

具体实施方式
下面通过实施例的方式进一步说明本实用新型，但并不因此将本实用新型限制在所述的实施例范围之中。
如图1至4所示，本实施例提供了一种换电站100，用于供电动汽车进行电池更换操作，具体包括电池拆卸与安装。具体地，换电站100包括作为底部结构的底板10和主体部20，底板10用于承载整个主体部20，即主体部20全部安装在底板10上。主体部20整体可划分为电池存储区21和电池更换区22，电池存储区21用于存储电池包，电池更换区22用于对电动汽车进行电池更换。具体地，电池存储区21和电池更换区22内还分别设有用于进行电池存储和电池更换的多个换电相关设备。基于此，所有的换电相关设备都将安装或固定在底板10上。
具体地，如图2所示，在电池存储区21内设置的换电相关设备包括用于存储电池包的电池架211，电池架211沿竖直方向具有多个电池仓位，每 个电池仓位分别用于存储电池包；还包括电池转运设备212，电池转运设备212具有被设置为垂直升降移动的轿厢，轿厢内设有可伸缩移动的伸出机构，通过将电池转运设备212与电池架211相对设置，使得轿厢能够与电池架211上的每个电池仓位相对准，从而通过伸出机构伸缩移动从电池仓位内取出电池包或放入电池包，实现电池转运过程。
如图3所示，底板10是一种由混凝土预制形成板状结构的预制式换电站底板，通过混凝土材料预先制成，其上一体形成有用于安装主体部20的底部结构。
在一具体实施方式中，底板10可以采用C30混凝土材料一体预制成型，满足底板10的高精度需求，节约底板10的生产周期，从而减少换电站的建站周期。另外，底板10还可以是采用C30混凝土材料预制形成多个模块，再由多模块拼接形成底板10，多模块拼接则便于运输，节约运输所需成本。由此可见，底板10的生产过程可根据实际生产需求定制，满足不同生产需要，灵活多样，适用范围广。
基于上述电池存储区21的结构，底板10在电池存储区对应的预定位置上形成有设备安装区域11，设备安装区域11用于安装电池转运设备，即设备安装区域11设置在与电池架211在底板10上的安装位置相对的位置上，从而使电池转运设备212能够被安装在合适的转运位置上。
具体地，设备安装区域11具有凹陷于底板10的表面的凹陷区，并且凹陷区与电池架211相对设置，通过凹陷区来容纳部分的电池转运设备212，一方面给能够确保电池转运设备212的准确定位与安装，从而使电池转运设备被安装在与电池架211相匹配的位置来进行电池转运，提高电池转运设备的安装精度，实现高效地电池转运过程。另一方面，能够增加轿厢的下降空间，使其能够与电池架211最底部的电池仓位进行电池转运，解决因轿厢自身厚度而占用下降行程而限制其下降移动的最低点位置，给电池架211最底部的电池仓位的电池转运带来不便；尤其是当电池架211沿竖直方向设置有 更多层的电池仓位时，每层电池仓位的高度将被最大限度压缩，极易造成最底部的电池仓位没有足够的空间进行电池转运。
在本实施例中，通过混凝土预制形成换电站底板用来安装换电站的主体部，所有安装换电相关设备所需的安装结构都可以一体形成于混凝土结构中，保证设备安装精度非常高，彻底解决了现有的换电集装箱的设备安装结构复杂、安装精度低的问题，同时也无需对建站场地进行复杂的地面处理，通过预制的混凝土底板即可满足换电站整体的水平度需求，而且通过混凝土底板对换电站的主体部进行承载，提高了换电站整体稳固性。具体地，针对换电站内用于进行电池转运的电池转运设备，该预制的混凝土底板在电池存储区的对应位置预先形成凹陷区来安装电池转运设备，满足了电池转运设备的安装精度需求，从而能够与电池存储区内的每个电池仓位对准设置，实现快速地电池转运需求，提高转运效率。
其次，基于混凝土预制形成的底板，能够在敞开的环境中直接在换电站底板上对所有的换电相关设备安装完成，使得每个换电相关设备都具有充足的安装空间，便于操作，在所有设备安装完成后再进行换电站***结构的安装，例如将集装箱罩设在底板上，使换电站的建站过程更方便，缩短换电站建设周期，降低换电站建设成本。
在具体实施时，凹陷区长度方向的尺寸与电池架长度方向的尺寸相匹配以容纳的轿厢长度；或者凹陷区的尺寸略大于电池架长度方向的尺寸，在满足容纳轿厢的同时，还可以对底板10整体的重量起到减重作用。
在一具体实施方式中，凹陷区包括第一凹陷部12，第一凹陷部12用于容纳部分的轿厢。具体地，第一凹陷部12的凹陷深度即是对轿厢的容纳量。这里只需将轿厢的长度设置为不小于第一凹陷部12的长度即可，使得可升降移动的轿厢能够下降至低于底板表面的位置，增加了电池转运设备的升降行程，增大对电池架最底部的电池仓位进行电池转运所需的空间，同时也利于增加电池架的电池仓位数量，即增加换电站的电池包容量。
在另一具体实施方式中，电池转运设备还包括用于驱动轿厢升降移动的驱动机构，基于此，凹陷区还包括第二凹陷部13，第二凹陷部13用于容纳部分的驱动机构。具体地，第二凹陷部13的凹陷深度即是对驱动机构的容纳量。这里只需在驱动机构的安装位置对应的区域内设置第二凹陷部13即可，使其可低于底板的表面设置，增加了驱动机构的安装空间，避免对电池转运设备的升降行程产生干扰或影响，结构布局更为合理。
在一优选地实施方式中，凹陷区包括一个第一凹陷部12和两个第二凹陷部13，第一凹陷部12设置于中间位置上，两个第二凹陷部13分别位于第一凹陷部12两侧的位置上。通过将可升降移动的轿厢设置在凹陷区中间的第一凹陷部12内，而驱动机构设置在两侧的第二凹陷部13内，从两侧对轿厢进行升降移动提供驱动力，保证轿厢的升降移动更平稳快速。进一步地，将第二凹陷部13的凹陷深度设置为大于第一凹陷部12的凹陷深度，这样，能够将安装驱动机构的第二凹陷部13设置在距离底板10的表面更深的位置上，为驱动机构的安装提供更多的向下空间，在满足增加轿厢的升降行程的同时还避免了驱动机构对轿厢的升降移动的干扰，整体结构更简洁。
在一具体实施方式中，底板10采用C30混凝土材料预制形成，基于该材料与结构要求，将第一凹陷部12的深度值设置为小于底板10整体厚度的20％，将第二凹陷部13的深度值设置为小于底板10整体厚度的50％。根据底板生产所采用的C30混凝土材料，通过对第一凹陷部12和第二凹陷部13的深度值进行合理限定，在满足轿厢和驱动机构的安装所需空间需求的同时，保证底板10的强度不会受到影响。
在另一实施方式中，如图4所示，为了减轻底板10的重量，底板10内形成有多个减重区域14，通过在底板10内设置减重区域14，能够在不影响底板10的承载性能的基础上，大幅度减轻混凝土底板的整体重量，便于运输，降低运输成本。基于此，由于驱动机构的安装区域第二凹陷部已尽可能深地凹陷于底板的表面设置，因此，第二凹陷部13避让减重区域14设置， 最大限度的提供驱动机构的安装空间的同时，能够避免第二凹陷部13所在区域的底板10的强度受到影响而发生变形等。
在另一实施例中，电池转运设备212的具体结构还包括：至少具有两根纵梁的固定门架以及将轿厢连接于纵梁上的传动机构，驱动机构设置于任意的纵梁上，通过驱动机构驱动传动机构带动轿厢在两个纵梁之间升降移动。
基于该结构的电池转运设备212，如图3所示，将其固定安装在凹陷区内，需要将两根纵梁对应设置在第二凹陷部13内，并且在第二凹陷部13内预埋多个固定孔15，通过固定孔15对纵梁的底部进行固定，从而对电池转运设备212整体进行固定，而驱动机构固定在任意的纵梁靠近底部的位置上，也就实现了对驱动机构的安装固定。
在该结构中，对纵梁的固定方式可以为：如图3所示，将多个固定孔15设置在第二凹陷部13的中心位置，纵梁的底部具有法兰连接面，这样，通过固定件连接法兰连接面与多个固定孔即可实现对纵梁进行固定，固定方式结构简单，进一步优化了电池转运设备的纵梁结构。
对纵梁的固定方式还可以为：如图5所示，在纵梁的底部设置固定板，固定板的长度与第二凹陷部12的宽度相匹配，固定板的两端分别设有多个连接孔，在第二凹陷部13的两端分别预埋多个固定孔15，这样，通过固定件分别连接两端的连接孔与对应的固定孔，从而对纵梁进行固定，每根纵梁通过两个位置进行固定连接，提高了电池转运设备212整体的稳定性。
在另一实施例中，如图1所示，电池架211的具体结构包括相间隔设置的两列架体，凹陷区设置于两列架体的中间区域内，因此，两列架体具有邻近凹陷区设置的四根立柱。基于该电池架211的结构，电池转运设备212的具体结构还包括：连接于轿厢的四个端部位置与对应的立柱之间的四个传动机构以及用于驱动四个传动机构的至少一个驱动机构。通过至少一个驱动机构向四个传动机构提供驱动力从而带动轿厢升降移动，这里，驱动机构的数量可以与传动机构的数量相同，也可以不同，相同时，驱动机构一一对应传 动机构提供驱动力；不同时，通过联动机构带动关联的多个传动机构即可。该电池转运设备212采用相邻设置的电池架的四根立柱进行传动机构安装以实现升降移动导向，使电池转运设备212的自身结构更简化，降低生产成本。
基于该结构的电池转运设备212，将其固定安装在凹陷区内，如图5所示，需要在第二凹陷部13内与四根立柱相对应的位置分别预埋多个固定孔15，通过固定孔15将至少一个驱动机构分别固定在与立柱相匹配的位置上，从而向对应的传动机构提供驱动力，实现驱动轿厢升降移动。这里，预埋固定孔15的位置与驱动机构的数量相关联，在需要安装驱动机构的对应位置预埋固定孔15即可，实现对驱动机构的固定安装。
在另一实施例中，换电站100的主体部20还可以设置为包括两个电池存储区21，以扩大换电站100的电池总量需求。两个电池存储区21分别设于电池更换区22的两侧，相应地，底板10则在两个电池存储区21的中间位置分别设置一个凹陷区，从而为每个电池存储区21内的电池架211提供匹配安装电池转运设备212的安装空间，使换电站100整体结构布局紧凑、更合理，而凹陷区的具体结构则与上述方案相同，也具有同样的作用效果。
虽然以上描述了本实用新型的具体实施方式，但是本领域的技术人员应当理解，这仅是举例说明，本实用新型的保护范围是由所附权利要求书限定的。本领域的技术人员在不背离本实用新型的原理和实质的前提下，可以对这些实施方式做出多种变更或修改，但这些变更和修改均落入本实用新型的保护范围。
