Description

一种水下密封舱 技术领域
本实用新型总地涉及水下舱体技术领域，具体涉及一种水下密封舱。
背景技术
随着海洋开发事业的发展，水下舱体随之出现。水密性是水下舱体功能实现的前提和关键。目前水下舱体的密封方式，多为镜像密封及端面密封，对于应用于深水环境的硬质塑料壳体而言，无法避免塑料长期形变带来的漏水问题，因此，现阶段大多数水下舱体均使用金属作为壳体材料，重量及成本较高。
典型的端面密封结构包括密封本体，密封本体具有开口朝上的密封腔，密封腔开口边缘上设置密封圈以及安装孔。将需要密封的器件安装于密封腔中后，需将与密封腔匹配的端盖盖合在密封腔的端面上，并通过安装孔进行固定，从而实现封装。
在上述的典型端面密封结构中，可以看出，在使用硬质塑料作为水下舱体的壳体时，塑料壳体变形的一个主要原因是密封圈对塑料壳体的向外挤压导致的。这是因为密封圈一般为柔性材料制成，具有一定弹性，能够产生向外的压力，导致塑料壳体受到向外的压力产生变形，从而影响了水下舱体整体的密封性能。
实用新型内容
鉴于上述背景技术存在的问题，为了能够得到一种密封失效低且成本低廉的水下舱体，有必要提出一种新的水下密封舱。本实用新型的目的在于提供一种水下密封舱，以解决现有情况下成本高、易失效等问题。
本实用新型提供一种水下密封舱，其包括：舱体，具有侧壁；舱盖，具有侧壁，舱盖的侧壁的底部和舱体的侧壁的顶部中的一个设置有凹槽，另一个设置有凸起部，凸起部插入凹槽内；柔性密封件，位于凹槽内，并被挤压设置于凸起部与凹槽的侧壁之间。
在上述的水下密封舱中，凹槽在远离柔性密封件的一侧还设置有挡墙，挡墙紧贴于凸起部，以限制凸起部的位置。
在上述的水下密封舱中，舱盖可以选择为一体成型。
在上述的水下密封舱中，舱体可以选择为一体成型。
在上述的水下密封舱中，凹槽比凸起部的刚性大。
在上述的水下密封舱中，柔性密封件可以为橡胶密封圈。
在上述的水下密封舱中，舱盖与所述舱体之间可以填充有密封胶体，增加密封效果，亦可以不填充。
在上述的水下密封舱中，凹槽与舱盖的侧壁的底部或舱体的侧壁的顶部之间为刚性连接。
在上述的水下密封舱中，挡墙和凹槽的底部之间为刚性连接。
在上述的水下密封舱中，凸起部的顶端抵靠于凹槽的底部。
这种水下密封舱的使用能够降低水下舱体的成本，避免舱体水下长期受压变形造成的密封效果变弱，并提高了舱体的使用寿命。

具体实施方式
以下结合附图和实施例，对本实用新型的具体实施方式进行更加详细的说明，以便能够更好地理解本实用新型的方案以及其各个方面的优点。然而，以下描述的具体实施方式和实施例仅是说明的目的，而不是对本实用新型的限制。
本实用新型中的“连接”，除非另有明确的规定或限定，应作广义理解，可以是直接相连，也可以是通过中间媒介相连。在本实用新型的描述中，需要理解的是，“上”、“下”、“前”、“后”、“左”、“右”、“顶端”、“底端”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，仅是为了便于描述本实用新型和简化描述，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，因此不能理解为对本实用新型的限制。
第一实施例
本实施例提供了一种水下密封舱，具体结构如图1和图2所示。图1为本申请第一实施例的水下密封舱的整体示意图，图2为本申请第一实施例的水下密封舱的密封位置Ⅰ的结构示意图。
如图1所示，图1示出了本申请第一实施例的水下舱体的整体示意图。可以看出，第一实施例中的水下舱体主要由舱盖101和舱体103构成，舱盖101和舱体103之间设置有柔性密封件102，用来完成对水下舱体内部整体的密封。
可以看出，舱盖101和舱体103是匹配的，舱盖101和舱体103合体而成一个封闭的结构。在安装完柔性密封件102后，舱盖101和舱体103之间还可以填充胶体以使用粘结方式进行密封，在本实施例中并未使用，但是本实用新型并不对其进行限制。
在本实施例中，舱盖101由硬质材料制成，一般选择高刚度的刚性材料，一般情况下即为金属。因为刚度高的刚性材料在水下压力的作用下，更难发生形变，而舱盖101的结构稳定保障了舱体103受到舱盖101形变产生的压力不会过大。因此，若舱盖101采用高刚度的刚性材料，舱体103相比较于舱盖101的材质要求会更低。但是，舱盖101的材质并不限定于金属，亦不限定于高刚度的刚性材料，只要选用合适的硬质材料即可。在本实施例中，舱盖101由金属制成，但是本实用新型并不对舱盖101的材质进行限定。
舱盖101可以为一体成型，亦可为分别成型，然后在装配时再进行组装。本实施例中，舱盖101是一体成型的，但是本实用新型对此并不进行限制。
在本实施例中，舱体103由硬质材料制成，一般为硬质高分子材料，一般情况下可选择硬质PVC或者有机玻璃等。舱体103选择硬质的高分子材料制备主要是为了成本的考虑，但是，在不考虑成本的情况下，舱体103的材质并不限定于硬质PVC或者有机玻璃，亦不限定于硬质高分子材料，只要能够完成舱体内部的密封即可。在本实施例中，舱体103为硬质PVC材料制成，但是本实用新型并不对舱体103的材质进行限定。
舱盖103可以为一体成型，亦可为分别成型，然后在装配时再进行组装。本实施例中，舱盖103是一体成型的，但是本实用新型对此并不进行限制。
柔性密封件102一般情况下采用的即为密封圈，但是柔性密封件102并不限定于密封圈，能够产生密封效果的柔性密封件均可使用，比如柔性密封件102可以为灌胶后固化形成的固态胶。在本实施例中，柔性密封件102为橡胶密封圈，但是本实用新型并不对柔性密封件102的部件进行限定。
在本实施例中，柔性密封件102为橡胶密封圈，橡胶密封圈一般情况下即为靠柔性材料自身的弹性性能对紧靠的舱盖101和舱体103产生的外压力来对密封区域进行密封。但是，密封圈亦可采用气胎等形式，依靠密封圈内的气体对紧靠的舱盖101和舱体103产生外压力已完成密封区域的密封。本实用新型并不对此进行限制。
本实施例的水下舱体的密封位置I的结构示意图在图2中示出。
如图2所示，可以看出，舱盖101的侧壁在密封位置I处具有一个凹槽。此外，舱体103的侧壁在密封位置I中起到作用的主要为三部分，其一为凸起部103A，其二为第一平台103B，其三为第二平台103C。舱盖101在密封位置I中起到作用的主要为两部分，其一为凹槽侧壁101A，其二为挡墙101B。此外，舱盖101主要还包括第一上平台101C1和第二上平台101C2。
柔性密封件102设置于第一上平台101C1、凹槽侧壁101A的右侧、第二平台103C和凸起部103A的左侧构成的空间当中。其中，柔性密封件102的左侧紧贴于凹槽侧壁101A的右侧，柔性密封件102的右侧紧贴于凸起部103A的左侧；此外，柔性密封件102与第一上平台101C1或第二平台103C可以是接触状态，亦可以是不接触状态。在本实施例中，柔性密封件102与第一上平台101C1接触，而与第二平台103C不接触，但是本实用新型对此并不进行限制。
在本实施例中，第一上平台101C1和第二上平台101C2是非共面的，但是，第一上平台101C1和第二上平台101C2还可以是共面的，此时仅存在一个上平台，本实用新型并不对此进行限制。
此外，由图2可知，由于柔性密封件102的弹性作用产生的向外的压力，凸起部103A的右侧紧贴于挡墙101B的左侧。在本实施例中，凸起部103A的上侧抵靠于舱盖101的下平台101C，挡墙101B的下侧抵靠于第一平台103B。但是凸起部103A的上侧与舱盖101的第二上平台101C2可不接触，挡墙101B的下侧与第一平台103B亦可不接触，本实用新型对此并不进行限制。
由上述描述可知，由于柔性密封件102的向外压力，凸起部103A的右侧紧贴于挡墙101B的左侧，而由于本实施例中舱盖101为高刚度的金属材料制成，挡墙101B不易发生形变，因此紧贴于挡墙101B的凸起部103A亦不容易发生形变。这就有效地阻止了本实施例中硬质PVC制备的舱体103在受到柔性密封件102向外的压力所产生的变形，从而有效地控制了柔性密封件102的压缩量，不仅达到了密封防水要求，还降低了舱体103的形变量，从而提高了舱体103的使用寿命。
如上所述，可以看出，在本实施例中，密封位置Ⅰ处，舱盖101的侧壁具有一个凹槽，而舱体103的侧壁具有一个凸起部103A。但是亦可舱盖101的侧壁具有一个凸起部，而舱体103的侧壁具有一个凹槽，只要能够实现本实施例中的密封效果即可，本实施例并不对此进行限制。
第二实施例
本实施例在第一实施例的基础上提供了另一种水下密封舱，具体结构如图3和图4所示。图3为本申请第二实施例的水下密封舱的整体示意图，图4为本申请第二实施例的水下密封舱的密封位置Ⅱ的结构示意图。
图3示出了本申请第二实施例的水下密封舱的整体示意图，如图3所示，可以看出，相比于第一实施例，第二实施例在第一实施例的舱盖上方添加了一个附加舱盖201。因为第一实施例密封保护的主要是舱体和舱盖构成的内部空间，而第二实施例密封保护的是舱体和舱盖构成的下方内部空间及舱盖和附加舱盖构成的上方内部空间。
图4中示出了本申请第二实施例的水下密封舱的密封位置Ⅱ的结构示意图，如图4所示，因为舱体和舱盖的密封位置I已经在第一实施例中进行了描述解释，因此，第二实施例仅对密封位置Ⅱ进行描述与解释。
第二实施例中的密封位置Ⅱ主要由附加舱盖201和舱盖203构成，附加舱盖201和舱盖203之间设置有柔性密封件202，用来完成对水下舱体的舱盖和附加舱盖内部空间整体的密封。
可以看出，舱盖203的表面存在凹陷，而附加舱盖201和舱盖203的凹陷处是匹配的，附加舱盖201和舱盖203的凹陷处合体而成一个封闭的结构。在安装完柔性密封件202后，舱盖203和附加舱盖201之间还可以填充胶体以使用粘结方式进行密封，本实施例中并未使用，但是本实用新型并不对其进行限制。
在本实施例中，附加舱盖201和舱盖203的材质要求分别与第一实施例中的舱体103和舱盖101的材质要求一致，在此不进行赘述。
在本实施例中，柔性密封件202的要求与第一实施例的柔性密封件102的要求一致，在此不进行赘述。
如图3和图4所示，可以看出，在密封位置Ⅱ中舱盖203的侧壁具有一个凹槽。附加舱盖201在密封位置Ⅱ中起到作用的主要为三部分，其一为凸起部201A，其二为第一上平台201B，其三为第二上平台201C。起到作用的主要为两部分，其一为凹槽侧壁203A，其二为挡墙203B。此外，舱盖203还包括下平台203C。
柔性密封件202设置于第一上平台201B、凹槽侧壁203A的左侧、下平台203C和凸起部201A的右侧构成的空间当中。其中，柔性密封件202的左侧紧贴于凸起部201A的右侧，柔性密封件202的右侧紧贴于凹槽侧壁203A的左侧；此外，柔性密封件202与第一上平台201B或下平台203C可以是接触状态，亦可以是不接触状态。在本实施例中，柔性密封件202与第一上平台201B接触，而与下平台203C不接触，但是本实用新型对此并不进行限制。
在本实施例中，第一上平台201B和第二上平台201C是非共面的，但是，第一上平台201B和第二上平台201C还可以是共面的，此时仅存在一个上平台，本实用新型并不对此进行限制。
此外，由图4可知，由于柔性密封件202的弹性作用产生的向内的压力，凸起部201A的左侧紧贴于挡墙203B的右侧。在本实施例中，凸起部201A的下侧抵靠于舱盖203的下平台203C，凹槽侧壁203A的上侧抵靠于第二上平台201C。但是凸起部201A的下侧与舱盖203的下平台203C可不接触，凹槽侧壁203A的上侧与第二上平台201C亦可不接触，本实用新型对此并不进行限制。
由上述描述可知，由于柔性密封件202的向内压力，凸起部201A的左侧紧贴于挡墙203B的右侧，而由于本实施例中舱盖203为高刚度的金属材料制成，挡墙203B不易发生形变，因此紧贴于挡墙203B的凸起部201A亦不容易发生形变。这就有效地阻止了本实施例中硬质PVC制备的附加舱盖201在受到柔性密封件202向内的压力所产生的变形， 从而有效地控制了柔性密封件202的压缩量，不仅达到了密封防水要求，还降低了附加舱盖201的形变量，从而提高了附加舱盖201的使用寿命。
如上所述，可以看出，在本实施例中，密封位置Ⅱ处，舱盖203具有一个凹槽，而附加舱盖201具有一个凸起部201A。但是亦可舱盖203具有一个凸起部，而附加舱盖201具有一个凹槽，只要能够实现本实施例中的密封效果即可，本实施例并不对此进行限制。
上述说明提供的水下密封舱可用于水下压力舱、水下电子舱、水下浮力舱等水下舱体。但是，本实用新型提供的这种水下密封舱，不局限于水下舱体，还可以应用于水下其余需要防水的设备或者作为无水区域的气密舱或者气密结构。
最后应说明的是：显然，上述实施例仅仅是为清楚地说明本实用新型所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引申出的显而易见的变化或变动仍处于本实用新型的保护范围之中。
