Urban sewer filter device capable of preventing backward flow
The invention discloses an urban sewer filter device capable of preventing backward flow, and relates to the field of municipal environment. The problem that in the prior art, an urban sewer cannot prevent backward flow at the stormy weather can be solved, and the device comprises a sewer branched pipe which is mounted below the ground, the sewer branched pipe communicates with a sewer main pipe,a filter net and an upper cover are arranged in the sewer branched pipe, a net plate fixing base is mounted in the sewer branched pipe, the lower end of the net plate fixing base is provided with a conical opening, the upper end of the net plate fixing base is fixedly connected with a fixed net plate, the lower end face of the fixed net plate is provided with a guide rod, the guide rod is sleevedwith a plug assembly, the lower end of the plug assembly is provided with a buoyancy assembly capable of pushing the plug assembly to float upwards when the sewage in the sewer main pipe surges upwards, and the density of the buoyancy assembly is smaller than that of water. According to the device, a sewer can be prevented from backward flowing effectively, and the street environment is protected.
本发明公开了一种防止反水的城市下水道过滤装置，涉及市政环境领域，解决了现有技术中城市下水道在暴雨天气无法防止反水的问题，其技术要点是：包括下水管分管，下水管分管安装到地面以下，且下水管分管连通下水管总管，下水管分管内设有过滤网和上盖，下水管分管内还设有网板固定座，网板固定座的下端设有锥形开口，网板固定座的上端固定连接有固定网板，固定网板的下端面上设有导向杆，导向杆上套设有堵头组件，堵头组件的下端设有能够在下水管总管内污水上涌时推动堵头组件上浮的浮力组件，浮力组件的密度小于水的密度；本发明能够有效的防止下水道反水，保护街道环境。
