The invention discloses a pulse type air supplementing municipal sewage well lid. The pulse type air supplementing municipal sewage well lid comprises a base and a cover plate which are connected, thecover plate is provided with a first mounting hole which is through up and down in the axial direction, a pressing assembly capable of moving upwards to reset is arranged in the first mounting hole in a sleeved mode, a transmission assembly is connected to the lower portion of the pressing assembly; and the transmission assembly is connected with a movable compression plate arranged below the base, and an air bag is arranged on the movable compression plate. Through the structural design, the pressing assembly, the transmission assembly and the air bag form an air passage, external air can enter the air bag through the air passage, and the external air is further introduced into a sewage pipeline system so as to improve gas-phase components in the sewage pipeline system. According to thepulse type air supplementing municipal sewage well lid, power is provided by passing pedestrians and vehicles, the pressing assembly is extruded, external fresh air is sucked into the sewage pipeline,the concentration of harmful gas in the sewage pipeline can be effectively reduced, and gathering of a large amount of flammable, combustible and toxic harmful gas is avoided.

本发明公开了一种脉冲式补气市政污水井盖，包括连接设置的基座和盖板，盖板上沿轴向开设有上下贯通的第一安装孔，第一安装孔内套设有可向上移动复位的按压组件，按压组件下方连接设置有传动组件，传动组件与设置在基座下方的活动压缩板相连，活动压缩板上设置有气囊；通过结构设计，使得按压组件、传动组件和气囊构成空气通路，外界空气可以经空气通路进入气囊，进一步将外界空气引入污水管道系统，以改善污水管道系统内的气相成分。本发明借助过往行人和车辆提供动力，挤压按压组件，将外界新鲜空气吸入污水管道内，可有效降低污水管道有害气体浓度，避免大量易燃易爆有毒性的有害气体的集聚。
