Municipal engineering environment-friendly drainage system and drainage device

LIU WENBO / ZHAO YANMEI / HONG WEIFENG

The invention relates to the technical field of municipal drainage, in particular to a municipal engineering environment-friendly drainage system and drainage device. The municipal engineering environment-friendly drainage device comprises an embedded box installed in a drainage channel of a reservoir, a water passing cavity and a water outlet hole communicating with a municipal drainage pipe network are formed in the embedded box, a draining valve is installed in the water outlet hole and is provided with a drainage port, a plugging device is arranged below the draining valve, a magnetic control assembly is arranged in the draining valve, and a pressing transmission device connected with the magnetic control assembly is arranged on the draining valve. By pressing the pressing transmissiondevice, two permanent magnets of the magnetic control assembly move oppositely, and therefore the magnetic field intensity on the working pole face of the plugging device is added or subtracted, theaims of suction and unloading are achieved so as to open or close the drainage port of the draining valve, foreign matter is prevented from being sucked into the drainage channel of the reservoir, operation is convenient and environment-friendly, meanwhile, children are prevented from being adsorbed by the drainage port of the reservoir, and safety and convenience are achieved.

本发明涉及市政排水技术领域，具体涉及一种市政工程环保排水系统及其排水装置。市政工程环保排水装置包括安装于蓄水池排水通道内的预埋盒，预埋盒内部具有过水腔和与市政排水管网连通的出水孔，出水孔内安装有排放阀，排放阀具有排水口，排放阀的下方设置有封堵装置，排放阀内设置有磁控组件，排放阀上设置有和磁控组件相连的按压传动装置。本发明通过压迫按压传动装置，使得磁控组件的两个永磁体相对运动，从而实现封堵装置工作极面上的磁场强度的相加或者消减，从而达到吸持和卸载的目的，以此来打开或者关闭排放阀的排水口，防止异物被吸进蓄水池排水通道，方便环保，同时防止孩童被蓄水池排水口吸附，安全便利。
