Description

一种水下防水插座
技术领域
本发明属于用电设备领域，特别涉及一种可用于水下防水插座。
背景技术
一般地，水具有导电性，因为水中存在大量的导电离子和杂质。而且水会引起电路短路，使设备失效，甚至损坏设备。特别地，因水或其它原因漏电，可能会对人生命安全造成威胁。所以，用电设备总是会受到用水环境的限制，比如，水下电气设备、抗洪救灾、水下维护和检修、潜水作业和沐浴房等。在这些应用场景，往往需要用到电源插座，而如何实现电源插座的防水功能，是必然要考虑的重要问题。
水下用电设备为了达到标准的防水要求，通常采用一体化设计。例如，将电源从陆地上接入，水下部分采取全封闭措施，以此来达到防水的目的。但是这种设计太僵硬和笨重，往往都需要单独定制样式，无法更换、更改。一种设计只能对应一种环境，兼容性不高，而且造价高。另外，便携式电器则会在仪器内部配置电池，提供电能，虽然这种配置可以在不同场所使用，但是其电池容量有限，续航不足。因此，迫切地需要设计一款便携式防水插座，来提供长时间、安全、方便的工作条件，以满足人们生活和生产需要，于是设计出了各种不同类型的防水插座。
传统的防水插座常采用机械式插座来实现防水功能，其结构复杂，制造成本高；其次，传统的防水插座没有考虑深水压力对插座的破坏作用，插座极易受到损伤，从而引起安全事故；另外，环境泥沙对插座还有侵蚀作用，强大的冲击力对插座会造成严重破坏，以及插座在水中可能会悬浮，这都是亟待解决的问题。随着超疏水纳米纤维的兴起，可以考虑在传统插座的插孔处增设多层超疏水纳米纤维，实现对外界水环境与插座内部的隔绝，达到防水效果。还可以通过适当的外形设计，减小深水对插座的压力，以及增设挖挂重物，实现固定插座位置等功能。
发明内容
本发明提供一种密封性能好的水下防水插座。
本发明的技术方案是：
一种水下防水插座，防水插座包括插盒和插头，插头包括插脚和绝缘橡胶；插盒上设有插孔和外接电源线，插孔由密封圈、疏水插孔和多层疏水性纳米纤维组成；疏水插孔内设所述多层疏水性纳米纤维，所述疏水纳米纤维是将含SiO2-NPs和疏水化合物异氰酸酯的悬浮液喷涂在棉纤维基材表面而形成的。
进一步地，上述纳米纤维的水表面接触角>150°，单根棉纤维基材的直径约为μm量级；喷涂的疏水涂层厚度为纳米量级。
进一步地，上述多层疏水性纳米纤维将单根纳米纤维逐层堆叠，形成总厚度为5mm疏水纳米纤维垫；再用胶水将纳米纤维垫沿纤维径向的一端固定在所述疏水插孔内。
进一步地，上述防水插座上设有防护罩，所述防护罩通过铰链与插座的塑料壳体相连。
进一步地，上述防水插座上设有配重悬挂杆。
本发明的有益效果：本纳米纤维材料具有超疏水性，可以阻止外界环境中的水气进入插盒；同时纳米纤维还其中密封效果，阻碍水分进入到插盒内部。
其次，防护罩可以有效防止鱼类撞击，或高速沙石撞击而破坏密封圈。
附图说明
图1是水下插座整体结构图；
图2是水下插座插孔局部结构图；
图3为水下插座的插口的局剖面图；
图4是插头进入插孔过程示意图。
其中：1-插盒，2-插孔，21-密封圈，22-疏水插孔，23-多层疏水性纳米纤维，3-插孔防护罩，31-铰链， 32-防护罩线孔，4-配重悬挂杆，5-电源线，6-插头，61-插脚，62-绝缘橡胶。
具体实施方式
以下结合实例和附图对本发明的原理和特征进行描述，所举实例只用于解释本发明，并非用于限定本发明的范围。
参见图1，是水下插座整体结构图，电源线5从柱状塑料壳体1的一端进入水下插座的内部，并与内部的金属簧片连接；电源线5与呈柱状塑料插盒1之间是无缝紧密接触，保证进线端不会有水进入插座内部。防护罩3通过铰链31与呈柱状塑料壳体1相连，并能自由开合。防护罩3上有预留插头出线孔32。在水下环境恶劣，防护罩3可以有效防止鱼类撞击，或高速沙石撞击而破坏密封圈21。当插上插头后，闭合上防护罩3，整个水下插座的外形结构呈现圆柱状；
配重悬挂杆4提供悬挂配重的位置；
用户可根据不同的水下作业环境，选取不同参量的悬挂物。
参见图2，为水下插座的插孔局部结构图，密封圈21与水下插座的插孔2圆形外壁紧密贴合，疏水插孔22中布置有多层疏水性纳米纤维23。标识23只展示了疏水纳米纤维的局部俯视结构。
图3为水下插座的插口的局剖面图，疏水纳米纤维23采用多层排列方式逐层堆叠。
柱状塑料插盒1采用聚氯乙烯制成，聚氯乙烯具有良好的绝缘性、耐压性和高强度等优点。
防护罩3用采用聚丙烯制成，聚丙烯具有耐压性强、透光性好等优点。将含SiO2-NPs（二氧化硅纳米颗粒）和疏水化合物异氰酸酯的悬浮液喷涂在棉纤维基材表面上形成疏水纳米纤维。所述纳米纤维与水表面的接触角>150°，因此具有超疏水性。再用502胶水将纳米纤维逐层粘贴在插孔内壁。
如图4所示；疏水纤维的厚度，即插头的拔插方向，总体设置为5mm，图4给出的插头6进入插孔过程的示意图，绝缘橡胶62附着在插脚61后端，长度设置为10mm。当插头6插入时，疏水性纳米纤维23受到力的作用下发生形变，疏水性纳米纤维23与插脚61紧密接触，在疏水纳米纤维的作用下，因此插脚61不会将水带入插头内部；插头6的根部设置的10mm的绝缘橡胶62，可以保证插头在插入后与插孔的紧密接触，保持外界水环境与插板内部的隔离状态。
所述水下防水插座的防护等级可高达IP68。
