下面将参照附图对根据本申请的一些实施方式所提供的电缆防水密封结构进行详细地描述。
请参阅图1和图3，本申请提供一种电缆防水密封结构，包括电缆内芯100、电缆外皮200、紧固结构300和执行机构600。所述电缆内芯100外侧设置电缆外皮200，所述电缆外皮200为灌注成型的异型结构。所述执行机构600包括控制舱400和执行器500，所述控制舱400和所述执行器500一端开口。所述电缆内芯100穿过所述电缆外皮200，电缆内芯100一端位于所述控制舱400内，另一端位于所述执行器500内。所述紧固结构300将所述电缆外皮200密封固定在所述控制舱400和执行器500内。
在本实施例中，可选地，紧固结构300将电缆外皮200的端部分别固定在控制舱400和执行器500的开口端。从电缆外皮200端部穿出的电缆内芯100的两端分别插入控制舱400和执行器500内部。
通过紧固结构300将电缆外皮200的端部固定在控制舱400和执行器500的开口端，电缆外皮200端部能够对控制舱400和执行器500的开口端起到封堵的效果，因此从电缆 外皮200端部穿出的电缆内芯100处于密封的腔体内，从而使位于控制舱400和执行器500内的电缆内芯100与外界密封隔离。
在本实施例中，可选地，先将电缆内芯100放置在制作好的钢制型腔内，然后通过钢制型腔一次灌注成形需要的外皮材料，最终使电缆内芯100侧面附着电缆外皮200。由于电缆外皮200是同种材质一次加工灌注成形，可以避免因外界环境的冷热交替造成外皮剥落，降低了长时间使用的漏水风险，通过一次灌注包裹，也节省了大量加工时间和生产成本。
传统的线缆制作过程大多是通过一次性加工很长的且线径一致大小的外皮，然后利用防水胶直接灌封。虽然上述方法能在短时间内能起到防水密封的作用，但将两种不同的物质粘接在一起，在经过长时间冷热交替的温度变化以及高液压的环境，由于两种不同的物质收缩和膨胀系数不同，且两种物质粘接不牢等因素，最终会导致两者剥离而失去防水密封的效果。因此将电缆外皮200一次灌注成形能减少上述隐患的出现，确保装置的防水密封效果。
在本实施例中，可选地，电缆外皮200为弹性PUR材料，弹性PUR的电缆外皮200具有耐磨、耐寒、耐水和耐油污等特性。由于电缆内芯100需要很高的密封防水要求，而弹性PUR材料的电缆外皮200能够提供电缆内芯100密封防水所需的条件。因此使用弹性PUR材料的电缆外皮200能降低外部环境对电缆内芯100使用的影响，进而大大延长电缆内芯100的使用寿命。
请继续参阅图1，所述电缆外皮200包括长条形外皮210和圆盘形外皮220。所述长条形外皮210和所述圆盘形外皮220为一体结构，所述电缆内芯100从所述长条形外皮210端部穿出。
在本实施例中，可选地，电缆外皮200由两部分结构组成，包括包裹在电缆内芯100中间部分长度较长的长条形外皮210，以及成型在电缆内芯100端部的圆盘形外皮220。圆盘形外皮220的直径大于长条形外皮210的直径。圆盘形外皮220端面与对应的电缆内芯100的端部之间的距离大于长条形外皮210端面与对应的电缆内芯100的端部之间的距离，即当圆盘形外皮220与控制舱400或执行器500的开口端的端面接触时，长条形外皮210的端面位于控制舱400或执行器500内部。紧固结构300设置在圆盘形外皮220的端面外侧，紧固结构300能与圆盘形外皮220的端面紧密接触配合，使得圆盘形外皮220远离紧固结构300的端面能紧贴在控制舱400和执行器500的端面上。
若成型的圆盘形外皮220端面与同侧的长条形外皮210的端面平齐，则电缆内芯100从电缆外皮200穿出的位置刚好是电缆外皮200与控制舱400或执行器500端面接触处。一方面从圆盘形外皮220端面穿出的电缆内芯100没有电缆外皮200对其包裹过渡，不方 便电缆内芯100与控制舱400或执行器500的连接，可能会对电缆内芯100造成折损。另一方面电缆内芯100刚好处于圆盘形外皮220与控制舱400或执行器500接触配合的位置，如果接触位置产生缝隙，会直接影响到电缆内芯100。将圆盘形外皮220端面与长条形外皮210端面之间设置一定的间距，能对电缆内芯100起到防护作用。
请继续参阅图1，所述控制舱400和所述执行器500的开口端的端面均开设环形凹槽410，所述环形凹槽410与所述圆盘形外皮220配合连接。
在本实施例中，可选地，当需要对电缆内芯100进行防水密封处理时，将内部包裹着电缆内芯100的电缆外皮200两端分别插入控制舱400和执行器500内部，使得圆盘形外皮220端面与环形凹槽410内底面接触配合。圆盘形外皮220的外端面位于控制舱400和执行器500的端面外侧，紧固结构300的压力可以作用到圆盘形外皮220的端面，使得圆盘形外皮220内端面紧贴在环形凹槽410内端面，有利于提高控制舱400和执行器500的防水密封效果。
如图2所示，所述圆盘形外皮220与对应的所述环形凹槽410相对的端面成型有环形密封圈221，所述环形密封圈221能与对应的所述环形凹槽410内端面紧密贴合。
在本实施例中，可选地，当需要对控制舱400和执行器500内的电缆内芯100进行防水密封处理时，先将圆盘形外皮220插入对应的环形凹槽410内，确保圆盘形外皮220端面的环形密封圈221完整的贴合在环形凹槽410内端面上。然后通过紧固结构300对圆盘形外皮220产生向对应的环形凹槽410内的挤压力，确保环形密封圈221紧贴在环形凹槽410内端面而不产生缝隙，大大提高装置的密封防水性能。
请继续参阅图1，所述紧固结构300包括压块310和螺栓组件320。所述压块310能通过所述螺栓组件320分别固定在所述控制舱400和所述执行器500端部，同时所述压块310将所述圆盘形外皮220向所述环形凹槽410内压紧。
如图1和图3所示，所述螺栓组件320包括四颗螺栓321，所述压块310、所述控制舱400和所述执行器500端面均开设螺孔322。所述螺栓321能与所述压块310、所述控制舱400和所述执行器500上的螺孔322配合连接，从而将所述圆盘形外皮220固定在对应的所述环形凹槽410内。
在本实施例中，可选地，压块310端面、控制舱400和执行器500开口端所在的端面均沿环形均匀开设四个螺孔322，螺孔322内螺纹连接螺栓321。当需要将环形凹槽410处的圆盘形外皮220进行固定时，先将压块310贴在控制舱400和执行器500的开口端面上，并将压块310的螺孔322与控制舱400和执行器500的螺孔322对齐。然后将螺栓321拧入螺孔322内，由于圆盘形外皮220的端面位于环形凹槽410外，在拧动螺栓321时，压块310逐渐向控制舱400或执行器500一侧移动，压块310挤压圆盘形外皮220，圆盘形 外皮220与环形凹槽410之间越贴越紧，使得环形密封圈221分别将控制舱400的内外和执行器500的内外分隔开，从而达到对电缆内芯100防水密封的作用。
请继续参阅图1和图4，所述压块310包括可拆卸配合连接的第一对分压块311和第二对分压块312，所述第一对分压块311和所述第二对分压块312均能通过所述螺栓组件320固定在所述控制舱400或所述执行器500端部。
在本实施例中，可选地，第一对分压块311和第二对分压块312合拢时能形成完整的圆环结构，将长条形外皮210卡在两者之间。第一对分压块311和第二对分压块312端面与圆盘形外皮220相对的端面接触配合。第一对分压块311和第二对分压块312的端面在180°的半圆周方向上等距开设三个螺孔322。其中有两个螺孔322位于第一对分压块311和第二对分压块312搭接重合的位置，且第一对分压块311和第二对分压块312相互搭接处的两个螺孔322具有相同的轴线。螺栓组件320对圆盘形外皮220进行固定时，螺栓321能穿过第一对分压块311和第二对分压块312上的螺孔322，圆盘形外皮220无法相对控制舱400和执行器500产生移动，有利于保护电缆内芯100不受外界影响。
在本实施例中，可选地，由于第一对分压块311和第二对分压块312具有相互搭接的结构，相比普通的半圆环结构仅能实现简单的接触配合，本实施例中的第一对分压块311和第二对分压块312卡接在一起后，能通过螺栓321将两部分固定在一起。第一对分压块311与第二对分压块312之间连接的越紧密，则越不容易产生变形，对圆盘形外皮220的紧固效果也越好，对电缆内芯100的防水密封效果也越好。
在本实施例中，可选地，第一对分压块311和第二对分压块312为可拆卸的结构，当第一对分压块311或第二对分压块312发生损坏需要更换时，将螺栓321拧开即可快速对其进行更换。若第一对分压块311和第二对分压块312为一个整体的圆环结构，当第一对分压块311和第二对分压块312的结构出现部分损坏需要对其进行更换时，难以将其快速拆下，不利于进行更换。
若放任损坏的第一对分压块311和第二对分压块312继续使用，则可能导致对圆盘形外皮220的压紧效果不合格，进而影响对电缆内芯100的防水密封。若强行破坏整个圆环结构，则无法将新的圆环结构套设在长条形外皮210侧面，导致无法通过紧固结构300对圆盘形外皮220的进行紧固。若通过更换整个结构来保证电缆内芯100的防水密封，则大大提高了生产制造的成本。
