本发明提供的灌胶型线缆引入结构及灌胶密封方法所具有的有益技术效果如下：
①本发明提供了一种灌胶型线缆引入结构，隔板本体设有用于穿设线缆的隔板通孔，第一凸环外壁与线帽环形槽内壁设有对应适配的螺纹段，本发明通过螺纹段拧合使得线帽连接在隔板本体外侧并在线帽与隔板本体之间形成灌胶空间，并通过线帽设有的若干与所述灌胶空间连接的灌胶功能孔实现灌胶操作，这种合理化技术方案不仅有利于优化机械结构、简化安装步骤、降低生产、装配及维修成本，更是提供了一种能够有效控制密封胶外溢及具有良好防水密封效果的线缆引入结构，避免了原料浪费，降低了产品不良率；

具体实施方式
实施例1：
在进行机械装配时，线缆往往需要通过穿孔/穿板操作，普通的引入装置由于机械连接关系往往密封不严，结构之间易出现间隙，无法做到高精度的防水，或是为达到高精度要求，往往结构较为复杂，成 本过高。因此，针对上述技术问题，本发明提供了一种灌胶型线缆引入结构，如图1所示，包括待引入线缆的隔板本体(1)、线缆(2)以及线帽(3)，隔板本体(1)设有用于穿设线缆(2)的隔板通孔(11)，在环该通孔周缘向隔板外侧延伸有第一凸环(12)，第一凸环与线帽(3)可拆卸连接在隔板本体外侧并在线帽与隔板本体之间形成灌胶空间(4)，线帽还设有若干灌胶功能孔(33)，灌胶功能孔与所述灌胶空间连接。为进一步合理化结构，本实施例具体结构如图1所示，在环通孔(11)周缘向隔板外侧延伸的第一凸环(12)外壁设置有螺纹段，线帽(3)设有与隔板通孔同轴的线缆孔(31)并环线缆孔在线帽一侧配置有内部环形槽(32)，在环形槽内壁设置有与第一凸环对应适配的螺纹段，通过螺纹拧合使得线帽连接在隔板本体外侧并在线帽与隔板本体之间形成灌胶空间，并通过线帽设有的若干与所述灌胶空间连接的灌胶功能孔实现灌胶操作，这种合理化技术方案不仅有利于优化机械结构、简化安装步骤、降低生产、装配及维修成本，更是提供了一种能够有效控制密封胶外溢及具有良好防水密封效果的线缆引入结构，避免了原料浪费，降低了产品不良率。其中灌胶功能孔(33)包括灌胶孔及出胶孔，线帽设有至少一个灌胶孔和至少一个出胶孔，为合理化灌胶过程，灌胶孔及出胶孔在线帽相对于所述线缆孔(31)径向对称布置，在本实施例中，如图2所示，线帽(3)设有四个灌胶功能孔(33)，其中包括两组将对于线缆孔(31)径向对称布置的灌胶孔及出胶孔，其中灌胶孔及出胶孔间隔设置且连线夹角为90度，在其他实施例中，可以根据需要设置更多的灌胶孔及出胶孔并尽可能均匀设置。通过合理化灌胶功能孔的数量及设置方式能够使得密封胶在灌胶空间 内的填充流向更加均衡及密集，能够减少气泡并尽可能保证不同出胶孔所需灌胶时间的统一性。
现有的线缆防水引入结构还存在因线缆不易定位造成的密封性及防水性不良的情况。为解决上述技术问题，本发明中隔板通孔(11)两侧为楔形切口，线缆(2)穿过通孔并经由楔形切口前端向线缆径向方向压缩一预设形变量，该形变量使得线缆能够正常穿过通孔同时在线缆固定时，该压缩量使得线缆对通孔产生紧贴的应力能够支持线缆无缝紧贴在通孔内侧，并能够支持在一定的灌胶压力下，线缆与通孔的紧密接合设置不会被破坏，并一定程度上促使密封胶倾向于出胶孔的方向流动；此外，这样设置还使得其他位点相对于压缩位自然状态从而在压缩位两侧形成类横向漏斗状的卡位部，使得线缆的固定更加稳定，从而进一步保证灌胶操作过程的精准度及可控性。
为进一步合理化结构，线帽(3)在环形槽(32)远端内壁设置有螺纹段并通过该螺纹段与所述第一凸环(12)对应适配拧接，线帽在螺纹段上端还一体成型有一用于抵接所述第一凸环(12)的限位块(34)，使得线帽不易移位。
灌胶功能孔(33)贯穿所述线帽并与环形槽连为一体，本实施例中灌胶孔对应环形槽开设，且直径与环形槽宽度一致。所述第一凸环(12)外侧拧接于环形槽(32)，其内侧与所述线缆(2)孔外壁之间缝隙宽度为3-10mm，外界通过所述灌胶功能孔及所述缝隙与灌胶空间(4)相连通。
实施例2：
采用灌胶方法进行密封的线缆穿墙结构受制于密封胶的流体特性，在灌胶作业时常常发生外溢，导致原料浪费及工件质量问题。为彻底解决上述技术问题，本发明在实施例1的基础上，提供了一种改进的灌胶型线缆引入结构，具体的如图3所示，在环所述隔板本体(1)通孔(11)周缘向隔板内侧延伸有第二凸环(13)，第二凸环的外壁设置有螺纹段且所述线帽(3)能够通过螺纹段对应拧合在隔板本体(1)内侧，上述设置使得线缆穿过隔板时，由线帽与隔板本体在隔板本体内外两侧分别封闭有用于注入密封胶的灌胶空间，通过灌胶操作，灌胶空间中的空气由灌胶功能孔排出并使得灌胶空间将线缆与隔板的穿设位包覆密封于内部，从而使线缆在穿过隔板时能够通过线缆引入结构进一步获得更好的气密性及防水性。
实施例3：
在实施例1和2的基础上，本实施例提供了一种船只，具有灌胶型线缆引入结构。由于船只需要设置有至少部分配置在船体外部的人机操作界面及电气部件，这些部件需要与设置于船体内部的中央控制器连接用于传输控制信号，但传统的密封方式往往密封效果较差，特别是在较高水压及流速条件下。本申请公开的船只可以根据需要在船体配置有该灌胶型线缆引入结构，使得船体内部有效区隔于船体外部水环境，并获得良好的密封性及气密性。
实施例4：
本实施例还提供了一种灌胶密封方法，能够通过观察出胶孔的溢 胶情况，预判不透明工件内部的密封胶填充情况，从而准确判断出灌胶操作的进程以及结束时间，使得灌胶密封过程获得更高的可控性及操作性，并能够有效提高良品率，具体包括如下步骤：
(a)提供一待引入线缆的隔板本体(1)、线缆(2)以及线帽(3)，隔板本体(1)设有用于穿设线缆(2)的隔板通孔(11)，在环通孔周缘向隔板外侧延伸的第一凸环(12)外壁设置有螺纹段，线帽(3)设有与隔板通孔同轴的线缆孔(31)并环线缆孔在线帽一侧配置有内部环形槽(32)，在环形槽内壁设置有与第一凸环对应适配的螺纹段；
(b)线帽(3)通过螺纹段拧合连接在隔板本体(1)外侧并在线帽与隔板本体之间形成灌胶空间(4)，线帽还设有若干灌胶功能孔(33)，灌胶功能孔与所述灌胶空间(4)连接，向灌胶型线缆引入结构的至少一个灌胶功能孔内以预设压强注入密封胶；
(c)以预设压强持续灌胶一段时间后，观察其他灌胶功能孔是否出现溢胶情况，如其他灌胶功能孔均出现溢胶情况，则停止灌胶操作。
为获得更好的灌胶效果，在步骤(b)中，应实时控制灌胶压强，以保证密封胶优先填充灌胶空间(4)，在灌胶操作结束前不会从隔板通孔(11)处溢出。
为进一步，在步骤(c)中，所述灌胶功能孔(33)包括灌胶孔及出胶孔，线帽(3)设有至少一个灌胶孔和至少一个出胶孔，如出胶孔出现溢胶情况，则停止灌胶操作，通过合理化灌胶功能孔的数量及设置方式能够使得密封胶在灌胶空间内的填充流向更加均衡及密集，能够减少气泡并尽可能保证不同出胶孔所需灌胶时间的统一性。
为进一步增强密封效果，还包括步骤(d)，环所述隔板本体(1) 通孔(11)周缘向隔板内侧延伸有第二凸环(13)，第二凸环的外壁设置有螺纹段且所述线帽(3)能够通过螺纹段对应拧合在隔板本体内侧，向隔板内侧线帽的灌胶功能孔(33)内以预设压强注入密封胶，并持续灌胶一段时间后，观察其他灌胶功能孔是否出现溢胶情况，如其他灌胶功能孔均出现溢胶情况，则停止灌胶操作。通过灌胶操作，灌胶空间(4)中的空气由灌胶功能孔排出并使得灌胶空间(4)将线缆与隔板的穿设位包覆密封于内部，从而使线缆在穿过隔板时能够通过线缆引入结构进一步获得更好的气密性及防水性。
