背景技术
柔性截流装置是一种应用在分流井的出水口或者排口的截流设施，其结构一般包括外壳体和橡胶套筒，外壳体与橡胶套筒之间形成充压腔体，橡胶套筒的端部与外壳体的端部通过法兰盘密封连接，当向充压腔体内充入有压气体时，橡胶套筒相对向内变形，橡胶套筒内壁贴合，流通通道截止。但是由于分流井对接的排水管道或者排口的管径较大时(如管径为DN400以上)，橡胶套筒的管径，不能够和变形量均较大，此时，橡胶套筒端部与外壳体端部在较大变形下，橡胶套筒端部滑出法兰盘和外壳体端部之间，充压腔体密封不好。而且外壳体的结构一般采用刚性结构，但是安装柔性截流装置的管道也是不可变性，柔性截流装置外壳体与管道的匹配性不好，往往是将外壳体的端部与管道的端部连接，柔性截流装置不能够安装在管道内，需要占用管道端部设置安装井，当柔性截流装置规格较大时所需要的安装井也越大，基础建设工程量大，施工效率低成本高，且后期维护不方便，因此，亟待一种能够解决密封问题方便安装的柔性截流装置。

(2)本发明的一种带有安装结构的橡胶套筒内设置一个独立的充压腔或者两独立的充压腔，橡胶套筒除了具有传统的关闭流通通道的功能以外，还具有截流功能，可以只对下充压腔进行充压，下充压腔的内层橡胶层向上隆起，充气变形后的橡胶套筒的下半部相当于一座可以调节高度的调节堰，当水位上升至截流高度以上时，水可以从上面进行溢流。这样可以拦截管道底部的积泥或者分流井内的积泥，防止底部的积泥随雨水进入自然水体，对自然水体造成污染。另外用在排水口处，能够根据自然水位情况，调节橡胶套筒下半部的截流高度，防止自然水体的倒 灌，在防倒灌的同时从橡胶套筒下半部的顶部溢流不影响行洪。
(3)本发明的一种带有安装结构的橡胶套筒设计成三向或者四向变形关闭截流通道的，将密封件填充于橡胶套筒关闭位置处的间隙中，且橡胶套筒关闭所使用的气压较小，可以实现在较低的压力(低于2bar)下即可实现零泄露，密封效果好，气压低，密封结构简单，也不影响流通通道的通行能力。

具体实施方式
下面结合附图及具体实施例对本发明作进一步的详细描述。
实施例1
参见图1至图13所示，本发明提供一种带有安装结构的橡胶套筒，包括橡胶套筒1和安装结构，橡胶套筒1设有贯穿的流通通道10，橡胶套筒1呈一体结构，且橡胶套筒1内设有至少一独立充压腔11，橡胶套筒1为一体化结构，且橡胶套筒1内设置至少一独立充压腔11每一所述充压腔11所在位置处的橡胶套筒1具有外层橡胶层12和内层橡胶层13；每一所述充压腔11的外层橡胶层12上设置进出孔，进出孔与该充压腔11联通；该安装结构包括两限位部2，两所述限位部2固定于橡胶套筒1的两端，夹持橡胶套筒1。本实施例中的形成充压腔11的橡胶结构与其他位置的橡胶结构为一体结构，由于橡胶套筒1并没有与其他部件共同组成充压腔11，无需设置密封结构用于密封充压腔11，以防止充压腔11泄露，结构简单，方便安装，适用范围广。橡胶套筒1只在两端固定，不在橡胶套筒1的管身上设置安装结构，拆卸方便，安装维护易操作。
优选地，作为具体实施方式，橡胶套筒1的结构具有以下几种形式：
橡胶套筒1的结构形式一，参见图2所示，本实施例中橡胶套筒1为圆筒状，橡胶套筒1内的充压腔11也为圆筒状，橡胶套筒1上设置有进出孔，通过进出孔给充压腔11充压，橡胶套筒1变形，流通通道19截止，通过进出孔给充压腔11充压，橡胶套筒1恢复变形，流通通道19导通；
橡胶套筒1的结构形式二，参见图4和图5所示，其中橡胶套筒1的截面形状为圆形，当设置一充压腔11时，充压腔11为下充压腔111，下充压腔111的截面形状为弧形下充压腔111的截面弧长小于所在截面的橡胶套筒1的周长，下充压腔111所在位置处的橡胶套筒1具有外层橡胶层12和内层橡胶层13，且外层橡胶层12和内层橡胶层13以及该充压 腔11以外的橡胶套筒1呈一体结构，其中下充压腔111的弧长可以占整个橡胶套筒1周长的二分之一也可是三分之二，根据截流高度的不同，可以设计不同规格，截流高度越高则下充压腔11的弧长越趋同于橡胶套筒的周长。下充压腔111的外层橡胶层12上设置有进出孔，进出孔与该充压腔11联通，通过进出孔充压，下充压腔111的所在侧的内层橡胶层13向上隆起一定的高度，相当于一座可以调节高度的堰，当内层橡胶层13贴合上半部分的橡胶套筒1内壁时，流通通道19截止，本结构中的下半部分的下充压腔111的内层橡胶层13隆起一定高度时，其顶部空间可以溢流，能够阻挡一部分的泥沙垃圾进入下游，也能够防止下游的水位过高时倒灌；
橡胶套筒1的结构形式三，参见图6和图7所示，设置两独立的充压腔11，分别为上充压腔110和下充压腔111，上充压腔110和下充压腔111分别设置于橡胶套筒1的上下两侧，上充压腔110所在侧的外层橡胶层12设置与上充压腔110连通的上进出孔，下充压腔111所在侧的外层橡胶层12设置与下充压腔111连通的下进出孔。
橡胶套筒1的结构形式四，参见图8所示，设置三独立的充压腔11，沿橡胶套筒1的周向分割成三份，每一份橡胶套筒1设置一充压腔11；或，参见图9所示，设置四独立的充压腔11，沿橡胶套筒1的周向分割成四份，每一份橡胶套筒1设置一充压腔11，每一充压腔11设置一进出孔。作为优选第，橡胶套筒1应当等份的分成三份或四份，保证每一份橡胶套筒1的内层橡胶层的变形相同，充压相同，方便控制。相对尺寸较大的橡胶套筒1，如采用上一或两个半体结构相对变形使得流通通道10截止，若是流通通道10的管径较大时，上下两侧的橡胶套筒1的变形量较大，所需要的压力较大，不仅密封效果不好，流通通道10不能实现零泄漏，而且存在爆炸的安全隐患，使用本实施例的三向或者四向变形关闭流通通道，每一独立充压腔的内层橡胶层变形量小，所需的压力较小，安全可靠，密封效果好，使用范围广。
进一步优选地，本实施例中的进出孔可以为设置在外层橡胶层12上的进孔和出孔的两孔，也可以为设置在外层橡胶层12上的一孔，在与该孔相连的输送管路上设置进管路和出管路。
进一步优选地，本实施例中限位部2的具体结构有以下几种形式：
限位部2的结构一，参见图3所示，限位部2包括折弯件和膨胀螺栓，折弯件具有具有连接一体的水平部20和竖直部21，水平部20设有安装孔，通过膨胀螺栓将水平部20固定在管道内，竖直部21的外侧抵持于橡胶套筒1的端部，两端限位部2的竖直部21共同作用夹持所述橡胶套筒1，其中折弯件为多个，间隔设置在橡胶套筒1的端部，方便拆卸，或者将折弯件设置为一体结构，折弯件的竖直部21的形状与橡胶套筒1端部的形状相适配，折弯件的水平部20的形状与安装环境下的管道的端口的形状适配；
限位部2的结构二，参见图13所示，限位部2包括折弯件，折弯件具有具有连接一体的水平部20和竖直部21，水平部20和竖直部21均设有安装孔，水平部20设有安装孔，通过膨胀螺栓将水平部20固定在管道内，橡胶套筒1的端部设置有连接板22，竖直部21与连接板22相连，其中橡胶套筒1的端部设置有安装连接板22的周向安装槽，且安装槽靠近竖直部21的一侧的截面宽度小于另一侧的截面宽度，呈横“T”型结构，折弯件的竖直部21的形状与连接板22的形状适配，折弯件的水平部20的形状与安装环境下的管道的端口的形状适配；
限位部2的结构三，参见图14所示，限位部2包括相连的固定端23和吊钩24，橡胶套筒1的端部设置有耳板25，耳板25与吊钩24可拆卸连接，其中固定端23为膨胀螺栓，安装状态下，将膨胀螺栓一端固定在管道或偏口的端口内，将吊钩24连接在膨胀螺栓的另一端，耳板25与吊钩24连接，当需要拆除时，将耳板25与吊钩24拆除，在将吊钩从膨胀螺栓的端部拆卸下来，安装维护简单易操作。
限位部2的结构四，参见图15-17所示，可以理解，在两个限位部 2中，其中的一个限位部2包括压板41和第一固定环421，该第一固定环421为一个环状结构的金属环，其内嵌在橡胶套筒1的一个端部上，压板41上设置有安装孔，安装时可通过膨胀螺栓一端穿过该安装孔固定在管道的端口部位处，而同时压板41抵压在橡胶套筒的一个端部上，以实现将该橡胶套筒1的一个端部固定在管道的端口部位处。另一个限位部2包括第二固定环422，该第二固定环422为一个环状结构的金属环，其内嵌在橡胶套筒1的另一个端部上。结合附图15-17，本领域技术人员可以理解，在该种限位部2的结构方式中，该橡胶套筒1可以直接塞入现有管道进行直接安装，结构简单，安装空间小，且为了橡胶套筒1的外壁与管道的内壁能够接触更加紧密，在本实施例中还设置有外罩体44，该外罩体44套设在橡胶套筒1的外围部位，并位于橡胶套筒1的外壁和管道的内部之间，使得橡胶套筒1在管道内的安装更加稳固，同时通过第一固定环421和第二固定环422可分别对橡胶套筒1的两端起到支撑作用，而且第一固定环421和第二固定环422可以一体化嵌入柔性套内，也可以做成可拆卸的，单独安装，达到安装维护简单易操作的技术效果。
更进一步的，在该种实施方式中，橡胶套筒1的一个端部和/或另一个端部上还可以设置有呈凸起结构的挡污部43，以阻挡管道内的淤泥、残渣等污染物流入橡胶套筒1与外罩体44之间的缝隙而造成额外的清洗、维护成本。
当然，上述限位部2的四种结构方式，仅是带有安装结构的橡胶套筒中安装结构的四种实现方式，同样的，针对橡胶套筒1的结构形式一、二、三也仅是橡胶套筒的多种实现方式，本领域技术人员可以理解，在限位部2的多种实现方式，以及橡胶套筒1的多种实现方式下的任意组合，所形成的若干种带有安装结构的橡胶套筒均是适用于本发明的，也是在本发明的保护范围之类的，不能以本发明实施例未穷尽所有组合方式而将未列入本发明实施例的其他组合方式排除在外。
实施例2
在实施例1的基础上，参见图1和图12所示，一种管道，在管道的端口3内安装有实施例1的带有安装结构的橡胶套筒；
橡胶套筒1的外壁与管道的端口3内壁贴合，安装结构2的限位部2固定于所述橡胶套筒1两端的所述管道的端口3内壁上，橡胶套筒1夹设于限位部2之间。
或者也可以参见图15-17所示的另一种管道，在管道的端口3内安装有实施例1的带有安装结构的橡胶套筒；橡胶套筒1的外壁通过外罩体44与管道的端口3内壁贴合，安装结构2的限位部2固定于管道的端口部位处，并且通过压板抵于所述橡胶套筒1的一个端部上，以及通过内嵌的第一固定环对橡胶套筒1的一个端部进行支撑，并在橡胶套筒1的另一个端部上也内嵌有第二固定环，并通过第二固定环对橡胶套筒1的另一个端部进行支撑。
本实施例中的橡胶套筒的结构，根据使用选择截流高度，下充压腔111充压隆起一定的高度，此时，下充压腔111的内层橡胶层隆起的高度相当于一座可以调节高度的堰，当充压较大时，隆起高度较高，截流高度也高，当充压较小或放压后，隆起高度较低，截流高度也较低，可根据实际使用情况而控制充压。当水位上升至截流高度以上时，水可以从上面进行溢流。这样可以拦截管道底部的积泥或者分流井内的积泥，防止底部的积泥随雨水进入自然水体，对自然水体造成污染。另外用在排水口处，能够根据自然水位情况，调节橡胶套筒下半部的截流高度，防止自然水体的倒灌，在防倒灌的同时从橡胶套筒下半部的顶部溢流不影响行洪。
本领域的技术人员可以对本发明实施例进行各种修改和变型，倘若这些修改和变型在本发明权利要求及其等同技术的范围之内，则这些修改和变型也在本发明的保护范围之内。
说明书中未详细描述的内容为本领域技术人员公知的现有技术。
