Description

一种长效全封闭水封防臭同层排水地漏 技术领域
本发明涉及建筑排水系统的同层排水地漏，尤其是一种全封闭水封防臭同层排水地漏。
背景技术
地漏是建筑领域中排水系统所采用的常用排水件，它是连接排水管道系统与室内地面的重要接口。地漏的用途是排除地面水，将水中的固体物、纤维物、毛发、易沉积物等进行过滤，同时，通过形成的水封隔绝排水管道中的废气，具有防止排水管道堵塞、防臭的作用。
在房屋装修中，地面的铺设层往往只有3cm至8cm，而国家标准GB50015－2003《建筑给水排水设计规范》节选4.5.9中规定水封高度不得小于5cm。目前，为达到国家标准对水封高度的要求，往往采用：(1)在下层铺设了存水弯，即采用隔层排水方式；(2)在同层排水中采用降板或升板安装方式。但是，隔层排水中排水横管和存水弯会占用下层楼层的空间而造成一系列麻烦和隐患，包括产权不明晰、噪音干扰、渗漏隐患和空间局限等，而且由于采用存水弯，容易发生堵塞。而在同层排水中，降板或升板安装方式会增加工程成本。因此，地漏问题是同层排水技术中的一个瓶颈。
目前，许多生产同层排水产品的厂家都在为开发新型的同层排水地漏而努力，市面上出现了多种用于同层排水的地漏，如：静水封横排地漏、自带水封防返溢侧墙地漏、自护水封防返溢多通道地漏、浮动罩防返溢多通道地漏等产品，虽然这些产品在一定程度上满足地漏的使用要求，但是，仍存在具有以下问题：
①地漏的密封不佳，且无防干涸作用，水封的水在长时间没有水补充的情况下，容易蒸发，无法起到防臭作用。
②受水封高度限制，地漏往往比较厚，对建筑结构和立管位置有要求，在 安装时不能灵活布置。
③安装、维修不方便：现有的各种地漏由于不能完全拆解或只可部分拆解，使用时地漏本身特别是管道出现堵塞，就不能进行拆解维修(疏通)并重新安装使用，只能破坏性拆除，令安装和维修非常不方便。
④防返水性能差，尽管大多数已有的地漏都在设计上考虑了防返水，但由于地漏内排水通道上存在钩挂毛发及纤维的结构，使用时因钩挂了毛发及纤维而使防返水失效。
⑤无阻隔，顺畅的排水效果差：同上，在原本就狭小的排水通道空间上，使用时因结构和钩挂了毛发及纤维的阻隔，而令过水面积进一步缩小，故不能达到顺畅排水的效果。
发明内容
本发明的目的是提供一种长效全封闭水封防臭同层排水地漏，可长时间保持水封，密封水不易蒸发，即使长时间不使用，也能有效地起到防臭防虫的作用。
本发明的目的可以通过以下技术措施来实现的：一种长效全封闭水封防臭同层排水地漏，包括同层地漏主体、地漏箅子和水封结构，所述地漏主体的侧壁具有至少一个管道接口，位于地漏主体内的水封结构是由水封外套与水封内套相套构成的竖截面为“山”字形水封，其特征是，在所述水封内套的下端与地漏主体底面之间空间里增设一个带气腔的防护浮子，所述防护浮子主体为一个与水封外套的内腔内径相适配的盘面，其盘面上靠近边缘的区域沿周边分布数个平衡孔，所述气腔设置在盘面的中部，凸起在所述水封内套中，用于利用地漏存水的浮力浮起至水封内套下端边缘以关闭所述水封内套的下端口；同时，在水封外套上方设置一环形的水封面板，该水封面板套于水封内套上，用于在地漏存水时在自身重力和气压的作用下与水封外套的顶端紧密接触，封闭水封内套与水封外套两者侧壁之间的竖向水道的上端口，并与防护浮子一起形成双密封圈，以便长久保留所述竖向水道中的水体和防护浮子主体与地漏主体底面之间的底部水体构成的杯状水体，达到长久水封的目的。
本发明在使用时，排水经过箅子的孔洞流入水封内套中时，由于水流的冲 力作用，防护浮子被下压而向下滑动，其下方的存水经压力平衡孔排至上方，防护浮子被压向地漏主体的底部，从而打开水封内套的下端口，接着排水进入竖向水道托起水封面板，使整个地漏与所述管道接口连接的排水管连通，令排水能顺利地通过地漏排入排水系统中。当排水完成后，地漏内部的存水会与水封外套的顶端平齐，同时，水封面板在重力作用下降至水封外套的顶端将所述竖向水道的上端口封闭，防护浮子则在其上方的水经平衡孔进入防护浮子下方空间时，在水体浮力的作用下向上浮起，止位于水封内套下端而封闭所述竖向水道的下端口，由于防护浮子封堵了水封内套的下端口以及水封面板封堵了所述竖向水道的上端口，构成双向密封，令水封内套、水封外套、防护浮子、水封面板所围闭的空间中的杯状水体不会被蒸发而干涸，即使水封内套中的水逐渐蒸发减少，由于负压的作用，防护浮子仍始终保持与水封内套接触的状态。如果排水管污水倒灌，所述的水封面板就能有效地阻挡住它，不至于返水至室内地面，同时双向密封还能长期有效地隔绝下水道的臭气。
本发明的目的还可以通过以下技术措施来实现的：一种全封闭水封防臭同层排水地漏，包括同层地漏主体、地漏箅子和水封结构，所述地漏主体的侧壁具有至少一个管道接口，位于地漏主体内的水封结构是由水封外套与水封内套相套构成的竖截面为“山”字形水封，其特征是，在所述水封内套的下端口与地漏主体底面之间空间里增设一个带弹簧防护浮子，该防护浮子包括片状浮板和弹簧，所述浮板与水封内套的下端口相适配，所述弹簧位于地漏主体底面和浮板之间，其两端分别抵于浮板底部与所述地漏主体的底面，在所述弹簧的作用力下，浮板抵住所述水封内套的下端口以封闭该下端口；同时，在水封外套上方设置一个环形的水封面板，该水封面板套于水封内套上，用于在地漏存水时在自身重力和气压的作用下与水封外套的顶端紧密接触，封闭水封内套与水封外套两者侧壁之间的竖向水道的上端口，利用所述的两道密封结构能够长久保留所述竖向水道中的水体和弹簧浮板与地漏主体底面之间的底部水体构成的杯状水体，达到长久水封的目的。
作为本发明第一种技术方案的一个实施例，所述防护浮子包括盘面和底托，所述盘面中部具有凸起的气腔，气腔的开口向下，所述底托是一个可拆式的密封气腔的封盘，其竖起的盘边上设置密封圈，使底托能密封住盘面气腔的开口。
本发明的第二种技术方案可以有以下的改进：
所述的防护浮子中的浮板可以采用金属薄板制成，或者采用其他能耐100℃高温的材料制成，以便在地漏在遇到接近100℃高温热水排水时，不会发生变形，从而提高密封的可靠性和使用场所的适应性。
所述浮板外轮廓与地漏的水封外套的内径相近，以确保浮板封闭水封内套下端口的可靠性，同时为确保浮板下方的水量补充顺畅，在浮板靠近边缘即大于水封内套直径的区域设置有均匀分布的数个平衡孔，以便使浮板上浮时能让其上方的水体顺畅地填充入浮板下方的空间中。
为了方便浮板的装拆及浮板始终能平稳地上下移动，所述防护浮子增设一个底壳，所述底壳为与水封外套的内腔内径相适配的带底面的圆筒，其筒内壁上设置至少二个或以上沿内壁周边对称分布的纵向限位结构，所述浮板的外廓尺寸与所述底壳内腔尺寸相适配，其周边也设有与底壳内壁上的纵向限位结构相对应并适配的限位结构，如底壳内壁上设置限位凸筋，相应的，浮板外廓上设置限位槽，或者两者对调，所述浮板和底壳通过相互配合的限位结构做滑动连接，使浮板在底壳内沿直线升降而不会发生偏移；在所述浮板周边对称均布有数个缺口作为平衡孔；所述弹簧位于底壳底面与浮板之间的空间内，其两端分别抵于浮板底部与底壳的底面。
进一步地，所述底壳内壁与浮板相配合的纵向限位结构为限位凸筋，4条限位凸筋沿底壳周圈均布在底壳内壁上，相应地，浮板外廓的限位结构为限位槽，浮板沿周边设有4个均布并与底壳的限位凸筋对应的限位槽，并且浮板上的平衡孔与限位槽合二为一，即限位槽同时也是平衡孔。
还可以分别在所述底壳底面和浮板底面对应设置弹簧定位槽，所述弹簧的两端分别安装在两个定位槽内，使弹簧中轴线和底壳以及浮板中轴线位于同一直线上，用于避免使用中因弹簧位置偏移而受力不均，浮板不能平稳地上、下移动，以确保浮板完全与水封内套下端口抵触密封。
所述底壳上端口设置限制浮板脱出的止脱结构，用于阻挡浮板从底壳中脱出，使第一密封结构成为一单独的组件，既方便装、拆第一密封结构，使之易于 更换维护；又有利于防止弹簧掉出受损。作为本发明的一个实施例，所述底壳上的止脱结构为止脱块，所述止脱块位于所述底壳的限位凸筋的顶端并从凸筋上向底壳中心方向径向凸起。相应地，所述浮板上也设置与底壳的止脱结构相对应并配合的止脱结构，所述浮板上的止脱结构为止脱台，它位于浮板的限位槽的下部，当浮板通过限位槽沿底壳限位凸筋移动至底壳上端时，所述止脱台与底壳上的止脱块相抵触，从而将浮板限制在底壳的高度内活动。
本发明以下的改进措施均适用于上述第一和第二并列的技术方案：
所述的水封结构是筒形的水封外套安装在地漏主体的底部，筒形的水封内套上缘具有外翻边，该外翻边的外径大于水封外套的外径，以便将水封内套安装在地漏主体上端口上；所述水封内套位于水封外套的内腔内，水封内套的外壁与水封外套内壁间具有环形水道，水封内套的下端与地漏主体底部之间具有间距，该间距与水封内套内腔和所述环形水道形成竖截面为“山”字形的地漏水封。
作为本发明的一种改进：所述防护浮子主体的盘面边缘向上延伸形成导向折边，该导向折边可避免防护浮子在受力不均时发生翻侧而卡在水封外套内，使防护浮子在水封外套内能顺畅地上下滑动。作为本发明的一个实施方式，所述导向折边的高度可以在5mm至10mm范围内。
本发明可以做以下改进：为适应地漏安装的楼板厚度和同层排水管安装深度不同的情况，所述地漏箅子与地漏主体上端口安装位之间设有可调节高度的管状箅子连接件，该箅子连接件外壁具有若干环形凹槽，可以根据地漏安装时的高度截取合适高度的箅子连接件，使箅子与水封内套的外翻边之间具有1cm至2cm间距。
本发明在以上改进措施的基础可以进行以下的改进：所述水封内套的上缘向外横向翻折后再竖向向下弯折形成拱形檐，所述拱形檐的下缘边是水封内套安装于地漏主体上端口的安装部位，所述水封外套的顶端伸入所述水封内套外壁和拱形檐内壁间的环形空间内，并与拱形檐的横向折面之间具有供水封面板上下活动的空间，所述水封面板位于所述空间内，同时，由于该水封内套的拱形檐设计使得水封内套的安装部位低于水封内套上端面，水封内套上端可伸入箅子连接件内，从而既满足了水封高度和水封面板活动行程的高度要求，又能尽可能地减小 地漏主体的高度，使得地漏做得更薄。
本发明还可以做以下的改进：所述水封内套的外壁上设有沿周边设一个用于承托水封面板的环形凸缘，该环形凸缘与水封外套的顶端齐平，所述水封面板在自身重力和气压的作用下与水封外套顶端和环形凸缘同时接触，以增强水封面板封闭环形水道的密封性。
本发明还可以再进行以下的改进：所述水封面板在其外边缘与环形水道外边缘之间的区域上沿一周分布数个气孔，使水封面板上部的气压与排水管道的气压一致，另外，所述水封面板的外边缘向下或向上或上下同时设置导向折边，使水封面板上下活动更为顺畅，即使在受力不均时也不会发生卡位，而影响其密封作用。作为本发明的一个实施方式，所述导向折边的高度可以在5mm至10mm的范围内。
本发明还可以进一步做以下的改进：所述水封内套的下端设有密封圈，该密封圈在与防护浮子主体紧密接触时起加强水封内套与防护浮子之间的密封性的作用。
本发明推荐的一个实施例是，在所述地漏本体的上端开口处增设一个用于水封内套和箅子或者箅子连接件定位安装的顶盖，该顶盖外环边缘向下翻折形成折边与地漏本体的上端开口处形成可拆式密封连接，其内环边缘向下延伸并形成两层台阶，其中，第一层台阶为箅子或者箅子连接件安装位，所述箅子或者箅子连接件可拆式密封连接于第一层台阶，第二层台阶为水封内套安装位，水封内套可拆式密封连接于第二层台阶。
本发明还可以进一步将所述地漏主体的内腔底部制成凹槽状，使所述水封外套的底端能够可拆式密封连接于该凹槽内，这样，本发明的地漏便成为可拆卸式地漏，地漏中的水封结构全部可拆卸出来，以便能够非常方便地清理地漏中的杂物、清洗地漏及疏通排水管道。
本发明还可做进一步改进，所述地漏箅子的中部设有用于穿插洗衣机出水管的通孔，该通孔的边缘向下延伸形成管体，在该管体下端套设掐管密封环，在箅子下方设置可密封箅子孔洞区域的环状防溢面板，该防溢面板套于所述管体上并 由掐管密封环的顶端承托，当进入地漏中的水量较大且无法及时排出时，防溢面板在水的浮力和冲击力作用下上升至与箅子接触，封闭箅子上的孔洞，防止水从箅子的孔洞反溢至地面。
本发明所述防溢面板可以是包括环形空心底座以及固定与底座顶面的环形密封圈，环形密封圈与箅子底面接触密封箅子的孔洞，提高防溢性能。所述防溢面板还可以只是一个环形密封圈。
与现有技术相比，本发明具有以下有益效果：
(1)本发明第一个技术方案是在所述水封内套的下端与地漏主体底面之间空间里增设一个带气腔的防护浮子，利用地漏存水的浮力浮起与水封内套下端边缘关闭水封内套下端口，同时，在水封外套上方设置一环形的水封面板，该水封面板在地漏存水时在自身重力和气压的作用下与水封外套的顶端紧密接触，封闭竖向水道的上端口，与防护浮子一起形成双向密封，封闭竖向水道中的水体和底部水体构成的杯状水体，不被蒸发而干涸，得以长久保留，达到长久水封的目的，能起到长效防臭防虫的作用。
(2)本发明第二个技术方案是在所述水封内套的下端与地漏的底盖的底面之间空间里设置弹簧浮板构成的防护浮子，利用弹簧的作用力将浮板始终抵触在水封内套的下端口，比第一个技术方案更为可靠：一是其封闭状态不会受地漏中的存水量的多寡影响，二是无需像第一个技术方案那样要顾虑对浮力的影响而只能选择轻薄塑料制作防护浮子，可以选择金属薄板或者能够耐100℃高温的其他材料制造浮板，令防护浮子不会因遇接近100℃高温的排水而导致变形，影响封闭效果。
(3)由于本发明的水封内套的顶端具有拱形檐，使得水封内套的安装部位可以低于水封内套上端面，水封内套上端可伸入箅子连接件内，从而既满足了水封高度和水封面板活动行程的高度要求，又能尽可能地减小地漏主体的高度，使得地漏做得更薄，即使地漏主体的高度在5cm以下，也能起到良好的水封效果，因此，地漏可以根据不同的铺设层厚度做成不同的厚度，且对建筑结构和立管位置没有特殊要求，能非常灵活地布置。
(4)本发明设置的箅子连接件可根据铺设层的厚度来调整地漏的高度，使地漏可适应各种厚度的铺设层的安装要求。
(5)本发明的水封结构各部件与地漏主体均为可拆卸连接，不但方便安装，而且特别方便地漏的清洗、清理和维护。

具体实施方式
实施例一：
图1和2所示的长效全封闭水封防臭同层排水地漏，包括同层地漏主体1、地漏箅子8和水封结构，地漏主体1的内腔底部制成凹槽状，其侧壁具有两个管道接口11，该两个管道接口11上设有管道连接件9，用于与排水管道连接。地漏主体1的的上端开口处设有用于定位安装的顶盖6。为适应地漏安装的楼板厚度以及同层排水管安装深度不同的情况，地漏箅子8与顶盖6安装位之间设有可调节高度的管状箅子连接件7，该箅子连接件7外壁具有若干环形凹槽，可以根据地漏安装时的高度截取合适高度的箅子连接件7，使地漏箅子8与水封内套3的外翻边之间具有1～2cm间距。
位于地漏主体1内的水封结构是由水封外套2与水封内套3相套构成。筒形 的水封外套2的底端可拆式密封连接于地漏主体1的内腔底部的凹槽内。筒形的水封内套3位于水封外套2的内腔内，水封内套3的外壁与水封外套2内壁间具有竖向环形水道，水封内套3的下端与地漏主体1底部之间具有间距，该间距与水封内套3内腔和环形水道形成竖截面为“山”字形的地漏水封。在水封内套3的下端与地漏主体1底面之间空间里增设一个带气腔44的防护浮子4，防护浮子4主体为一个与水封外套2的内腔内径相适配的盘面41，其盘面41上靠近边缘的区域沿周边分布数个平衡孔43，气腔44设置在盘面41的中部，凸起在水封内套3中，用于利用地漏存水的浮力浮起至水封内套3下端边缘以关闭所述水封内套3的下端口。同时，在水封外套2上方设置一环形的水封面板5，该水封面板5套于水封内套3上，用于在地漏存水时在自身重力和气压的作用下与水封外套2的顶端紧密接触，封闭环形水道的上端口，并与防护浮子4一起形成双向密封，以便长久保留竖向水道中的水体以及防护浮子4与地漏主体1底面之间的底部水体构成的杯状水体，达到长久水封的目的。水封内套3的上缘向外横向翻折后再竖向向下弯折形成拱形檐。拱形檐横向折面的折边的外径大于水封外套2的外径。拱形檐的下缘边是水封内套3安装于地漏主体1上端口的安装部位，水封外套2的顶端伸入水封内套3外壁和拱形檐内壁间的环形空间内，并与拱形檐的横向折面之间具有供水封面板5上下活动的空间，水封面板5位于该空间内，同时，由于该水封内套3的拱形檐设计使得水封内套3的安装部位低于水封内套3上端面，水封内套3上端可伸入箅子连接件7内，既满足了水封高度和水封面板5活动行程的高度要求，又能尽可能地减小地漏主体1的高度，使地漏能做得更薄。
水封内套3的外壁上设有沿周边设置的用于承托水封面板5的环形凸缘32，该环形凸缘32与水封外套2的顶端齐平，水封面板5在自身重力和气压的作用下与水封外套2和环形凸缘32同时接触，以增强水封面板5封闭环形水道的密封性。水封内套3的下端设有密封圈31，该密封圈31在与防护浮子4主体紧密接触时起加强水封内套3与防护浮子4之间的密封性的作用。
水封面板5在其外边缘与环形水道外边缘之间的区域上沿圆周分布数个气孔51，使水封面板5上部的气压与排水管道的气压一致，另外，所述水封面板5的外边缘上下同时设置导向折边，使水封面板5上下活动更为顺畅，即使在受力 不均时也不会发生卡位，而影响其密封作用。导向折边的高度在5mm至10mm的范围内。
防护浮子4由盘面41和底托42构成，盘面41中部具有凸起的气腔44，气腔44的开口向下，底托42是一个可拆式的密封气腔44的封盘，其竖起的盘边上设置密封圈，使底托42能密封住盘面41气腔44的开口。盘面41边缘向上延伸形成导向折边，该导向折边可避免防护浮子4在受力不均时发生翻侧而卡在水封外套2内，使防护浮子4在水封外套2内能顺畅地上下滑动。导向折边的高度可以在5mm至10mm范围内。
顶盖6外环边缘向下翻折形成折边与地漏本体1的上端开口形成可拆式密封连接，其内环边缘向下延伸并形成两层台阶，其中，第一层台阶为箅子连接件7安装位，箅子连接件7可拆式密封连接于第一层台阶，第二层台阶为水封内套3安装位，水封内套3的拱形檐的下缘边可拆式密封连接于第二层台阶。
在使用时，排水经过地漏箅子8的孔洞流入水封内套3中时，由于水流的冲力作用，防护浮子4被压而向下滑动，其下方的存水经压力平衡孔43排至上方，防护浮子4被压向地漏主体1的底部，从而打开水封内套3的下端口，接着排水进入竖向水道中托起水封面板5，使整个地漏与管道接口11连接的排水管连通，令排水能顺利地通过地漏排入排水系统中。当排水完成后，地漏内部的存水会与水封外套2的顶端平齐，同时，水封面板5在重力作用下降至水封外套2的顶端将环形水道的上端口封闭，防护浮子4则在其上方的水经平衡孔43进入防护浮子4下方空间，使防护浮子4在水体浮力的作用下向上浮起，止位于水封内套3下端而封闭其下端口，由于防护浮子4封堵了水封内套3的下端口及水封面板5封堵了竖向水道的上端口，构成双向密封，令水封内套3、水封外套2、防护浮子4、水封面板5所围闭的空间中的杯状水体不会被蒸发而干涸，即使水封内套3中的水逐渐蒸发减少，由于负压的作用，防护浮子4始终保持与水封内套3接触的状态。如果排水管污水倒灌，水封面板5能有效地阻挡住污水倒灌，不至于出现返水至室内地面的情况，同时双向密封还能长期有效隔绝下水道的臭气。
实施例二：
如图3所示，与实施例一不同的是：筒形的水封内套3上缘具有外翻边，该 外翻边的外径大于水封外套2的外径，外翻边的外边缘可拆式密封连接于顶盖6的第二层台阶上。
实施例三：
如图4所示，与实施例一或二不同的是：地漏箅子8的中部设有用于穿插洗衣机出水管的通孔，该通孔的边缘向下延伸形成管体81，在该管体81下端套设掐管密封环82，在地漏箅子8下方设置可密封箅子孔洞区域的环状防溢板10，该防溢板10套于管体81上并由掐管密封环82的顶端承托，当进入地漏中的水量较大且无法及时排出时，防溢板10在水的浮力和冲击力作用下上升至与箅子接触，封闭地漏箅子8上的孔洞，防止水从地漏箅子8上的孔洞反溢至地面。
防溢板10由环形空心底座以及固定于底座顶面的环形密封圈，环形密封圈与地漏箅子底面接触，密封地漏箅子8孔洞区域部分，提高防溢性能。
实施例四：
如图5所示，与实施例二不同的是：在水封内套3的下端与地漏主体1底面之间设置的防护浮子4由片状浮板45和弹簧46构成。浮板45由金属材料制成，以便在地漏在遇到接近100℃高温热水排水时，不会发生几何变形，从而提高密封的可靠性和使用场所的适应性。浮板45外轮廓与水封外套2的内径相近，其靠近边缘的区域沿周边即大于水封内套直径外的区域对称并均匀分布有4个平衡孔43，弹簧46位于地漏主体的底面与浮板45底面之间，其两端分别抵于浮板45底部与地漏主体1的底面，使浮板45在弹簧46的作用力下抵住水封内套3的下端口以封闭该下端口；在本实施例中，弹簧46的具体安装方式为：地漏主体1的底面和浮板41底面对应设置有固定弹簧的定位槽48，弹簧46的两端分别安装在两个定位槽48内，使弹簧46中轴线和地漏主体1以及浮板45中轴线位于同一直线上，这样能避免使用中因弹簧位置偏移而受力不均的情况，让浮板45平稳地上、下移动，确保浮板45完全与水封内套3的下端口接触密封。浮板45的边缘向下设置有导向折边，使浮板45上下活动更为顺畅。
实施例五：
如图6-8所示，与实施例四不同的是：
在水封内套3的下端与地漏主体1底面之间设置的防护浮子4由片状浮板45、弹簧46和底壳49构成。浮板45和底壳49均由耐100℃高温的材料制成，以便地漏在遇到接近100℃高温热水排水时，不会发生几何变形，从而提高密封的可靠性和使用场所的适应性。弹簧46位于底壳49底面与浮板45之间的空间内，其两端分别抵于浮板45底部与底壳49的底面。底壳49内腔底面和浮板41底面对应设置有固定弹簧的定位槽48，弹簧46的两端分别安装在两个定位槽48内，定位槽48使弹簧46中轴线和底壳49以及浮板45中轴线位于同一直线上。浮板45靠近边缘的区域沿周边即大于水封内套直径的区域对称并均匀分布有4个缺口451作为平衡孔。
底壳49为一个与水封外套2的内腔内径相适配的带底面的圆筒，该圆筒内壁上设置四个沿内壁周边对称分布的纵向限位结构，这四个纵向限位结构为限位凸筋47；浮板45的外轮廓尺寸与底壳49内腔尺寸相适配，其周边也设有与底壳49内壁上的纵向限位凸筋47相对应并适配的限位结构，该限位结构为限位槽452；浮板45和底壳49通过相互配合的限位槽452和限位凸筋47做滑动连接，使浮板45在底壳49内沿直线升降而不会发生偏移。
防护浮子4的底壳49的上端口还设置了限制浮板45脱出的止脱结构，该结构用于阻挡浮板45从底壳49中脱出，使防护浮子4成为一个单独的组件，既方便拆装，又便于维护，还有利于防止弹簧46掉出而受损。底壳49上的止脱结构为止脱块471。该止脱块471位于底壳49的限位凸筋47的顶端并从限位凸筋47上向底壳49中心方向径向凸起。相应地，浮板45上也设置与底壳49的止脱结构相对应并配合的止脱结构，该止脱结构为止脱台453，位于浮板45的限位槽452的下部，当浮板45通过限位槽452沿底壳49的限位凸筋47移动至底壳49的上端时，止脱台453与底壳49上的止脱块471相抵触，从而将浮板45限制在底壳49的高度内活动。
在本实施例中，水封内套3的下端密封圈31包裹水封内套3下端口的边缘。
本发明的实施方式不受上述实施例的限定，利用本领域的普通知识和惯用技术手段，在不脱离本发明技术思想的前提下，可对本发明做出其它形式的修改和替换，但经过修改和替换的技术方案均应落在本发明权利保护范围内。
