Description

一种精准出液的注液器 技术领域
本申请涉及太阳能电池技术领域，尤其涉及一种检测太阳能电池电位诱发衰减用的能够精准控制出液量的注液器。
背景技术
随着光伏发电在世界能源消耗中占有越来越重要的席位，在实际应用过程中，一个发电系统会集成多个光伏组件，组件会暴露在非常高的电压下，在长期高电压的作用下，组件中玻璃和封装材料之间存在漏电现象，使得大量电荷和Na+富集在电池片表面，造成表面钝化减反射膜失效，随后PN结失效，最终使得组件性能持续衰减，这种衰减被称为电位诱发衰减(Potential Induced Degration)，即PID效应。造成此类衰减的机理是多方面的，例如在上述高电压的作用下，组件电池的封装材料和组件上表面层及下表面层的材料中出现离子迁移现象；电池中出现热载流子现象；电荷的再分配削减了电池的活性层；相关的电路腐蚀；等等。近年来，在太阳能电池应用过程中，发生了诸多太阳能电池组件功率衰减的案例，严重影响了太阳能电池在各应用领域的广泛使用和推广。因此，对太阳能电池的PID监控极其重要。
目前为了能够实时监控太阳能电池片的抗电位诱发衰减性能，主要是采用在被测的太阳电池片上选取N个测量点，N为大于或等于1的自然数，取一定体积的测试液进行测量，测试该些测量点的接触角， 与标准数据库中的数据进行比较，得出被测太阳电池片是否合格的结论,从而对太阳电池片亲水性和/或亲水性阻挡层的均匀性进行有效管控。
而现有技术中，在向太阳能电池片上滴测试液时，还无法精确做到每个测试液液滴体积完全相同，而每次、每滴测试液体积不能保证一致，则对太阳能电池片的接触角测量也就不准确了，进而对太阳能电池片的抗电位诱发衰减性能监控也必然会不准确。

具体实施方式
现在结合附图对本申请作进一步详细的说明。这些附图均为简化的示意图，仅以示意方式说明本申请的基本结构，因此其仅显示与本申请有关的构成。
在申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”、“顺时针”、“逆时针”等指示的方位或位置关系为基于附 图所示的方位或位置关系，仅是为了便于描述申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对申请的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
在申请中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在申请中的具体含义。
如图1和图2所示，本申请提供了一种注液器，所述注液器2包括腔体部21和活塞杆22，所述腔体部21内设有相互连通的储液腔211、出液通道213和进液通道212，且所述储液腔211、出液通道213和进液通道212呈Y字型设置，所述腔体部21通过固定架4固定在固定物上，所述活塞杆的活塞端置于储液腔内，另一端与所述微泵的动力输出端相连接。
进一步改进为，所述活塞杆通过一U型卡件5与用于提供动力的微泵的动力输出端相连接，且所述固定物上开设有轨道孔，所述U型 卡件可沿轨道孔上下移动。
进一步改进为，所述U型卡件的一端开设有一卡口，且所述活塞杆上设有与卡口相匹配的卡槽。U型卡件的一端通过卡口卡住活塞杆，U型卡件的另一端通过螺栓固定活塞杆，此种结构使得注液器的装配及维护更加方便、快捷，便于维护。
进一步改进为，所述腔体部21为亚克力材质。亚克力材质的腔体部不仅质量轻，而且热变形温度较高，正常使用时不会发生形变，进而避免了由于腔体部形变而产生的注液量不稳定情况的发生。
进一步改进为，所述活塞杆22为氧化铝陶瓷材质。氧化铝材质的活塞杆不仅机械强度高，而且耐高温性能好，正常使用时不会发生形变，进而避免了由于活塞杆形变而产生的注液量不稳定情况的发生。
进一步改进为，所述阀门3为电磁阀，所述控制器控制电磁阀的开、关。通过电磁阀以及微泵的配合，实现了注液器的自动吸液和注液，无需人工控制阀门，实现了自动化控制，节省了人力。
进一步改进为，所述腔体部21设有一排气孔，所述排气孔与储液腔相连通，且所述排气孔与储液腔连通的通道上设有电磁阀，所述电磁阀与控制器相连接。若储液腔内有空气，则注液器的注液量必然会不准确，所以当储液腔内有空气时，控制器控制进液通道、出液通道的阀门关闭，打开控制排气孔导通的电磁阀进行排气，当气体排尽后再打开出液通道的阀门进行注液。
进一步改进为，所述流量检测设备6设置于注液器2的出液通道 上，用于检测注液器的出液量，通过流量检测设备能够对出液通道挤出的液体量进行实时检测，当检测的出液量与控制器设置的出液量不符时，控制器会进行报警提示；
所述液位计7设置于注液器储液腔上，用于实时监测注液器内的液量，当注液器内的检测液量低于控制器内的预设值时，控制器控制出液阀门关闭，打开进液阀门，进而补充检测液。
所述控制器8与阀门3、流量检测设备6、液位计7分别相连接。
本申请提供的注液器，腔体部为亚克力材质，所述活塞杆为氧化铝陶瓷材质。亚克力材质的腔体部不仅质量轻，而且热变形温度较高，正常使用时不会发生形变，进而避免了由于腔体部形变而产生的出液量不稳定情况的发生。所述活塞杆为氧化铝陶瓷材质。氧化铝材质的活塞杆不仅机械强度高，而且耐高温性能好，正常使用时不会发生形变，进而避免了由于活塞杆形变而产生的出液量不稳定情况的发生。
以上述依据本申请的理想实施例为启示，通过上述的说明内容，相关工作人员完全可以在不偏离本项申请技术思想的范围内，进行多样的变更以及修改。本项申请的技术性范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
