本申请的有益之处：1、在本申请的杠杆结构中，杠杆两端的左堵头和右堵头与左吸口和右吸口之间连接，杠杆通过浮球和液位的高低来实现对左吸口和右吸口的封堵，并且在左堵头和杠杆铰链之间设有的杠杆重锤能够实现杠杆结构的下落和平衡，当旋转结构对杠杆右杆进行转动的时候，杠杆重锤对左堵头有向下的压力。
2、本申请中的旋转结构的右轴向压杆和左旋杆和浮球短杆之间的配合能够实现对杠杆左杆和杠杆右杆的压制和释放，从而实现对左吸口和右吸口的封堵或释放，使得中继井具备高液位“瞬间打开常压吸口，闭合负压吸口“，低液位“瞬间闭合常压吸口，打开负压吸口”的功能。且开关果断，负压气管同常压管道的连通时间极短，节省了负压的消耗，进而达到节省吨水输送能耗的目的。
3、本申请中浮球结构中浮球短杆对旋转结构的向上和向下的拨动，实现对旋转结构的转动，浮球长杆通过与浮球的连接，浮球随着中继井内液位的高低上下浮动，并通过连接的浮球长杆的使用，使得中继井具备较大的启闭液位差的功能，同时维持较大的力臂，即使用较小的浮球即可达到驱动旋转杠杆的目的。
4、本申请进水管道上止回阀A的使用，使得中继井在泄压过程中，进水管道中保持负压而不泄压，减少了负压能的损失，排水管道上止回阀B的使用，使得中继井在抽真空过程中，排水管道中污水不倒流，提高了中继井传输污水的效率。
5、本申请可不依靠电能，以浮力、负压作为驱动力，自动周期运行，可实现高液位“瞬间打开常压吸口，闭合负压吸口”，低液位“瞬间闭合常压吸口，打开负压吸口”的功能，进而实现“中继井高液位排水，低液位进水”的功能，进而实现“中继井作为中间接力装置不依靠电能传输污水”的功能。
